Definitions
- the present invention relates to a cup-shaped receptacle and to a lid for such a receptacle.
- the outer surface of the outer leg wall of the lid recess extends downwards just slightly beyond the height position of the constriction.
- the cone angle and the outer diameter of the outer surface are matched with the cone angle and the inner diameter of the receptacle wall such that outer surface does not get in significant contact with the receptacle wall even when the bead of the receptacle, which is implemented as a curled rim, fully is seated on the clamping groove.
- the clamping groove tilts inwards during the clip-on movement; this hinders the bead to smoothly move over the whole circumferential length past the constriction. It is necessary to first manually centre the lid with the clamping groove neatly on the bead and then to clip on the lid by pressure directly acting on the upper wall of the clamping groove with a sliding rotating movement of the hand. This clip on action is troublesome, time-consuming and increases the risk that the bead does not properly snap into the clamping groove at some locations along the circumference of the cup opening. This has the effect that liquid may leak through when the full cup is tilted. The lid easily pops off inadvertently if the full receptacle falls over, because the cup opening region easily gets deformed radially.
- the outer leg wall has a relatively long downward extension
- the U-web of the lid recess, and the inner leg wall commonly constitute a rigid centring and guide projection which slidingly contacts the receptacle wall at least already while the bead moves past the constriction.
- the clamping groove automatically is precisely centred on the bead, and the bead is clipped-on virtually at one go and along its whole circumferential length, past the constriction into the clamping groove by applying pressure essentially only on the dome top wall.
- the sliding contact between the outer surface and the receptacle wall guides the constriction uniformly over the bead, since thanks to guidance and centring, the bead generates uniform resistance against the lid downward movement everywhere.
- the guiding projection converts the pressure applied to the dome into a downwardly oriented pulling force uniformly distributed along the constriction to pull the constriction uniformly past the bead, until the bead is correctly positioned in the clamping groove.
- This advantageous effect of the centring and guide projection, which actually is a cone or a cylinder, and the uniform force transmission, in co-action allow to provide a strong force fit between the bead and the clamping groove, said force fit resulting from a relatively narrow dimensioning between the bead and the clamping groove and the given elasticity. This assures that the clipped on lid prevents leakage, and that the bead does not even locally leave the clamping groove if the full cup falls over.
- the shape of the dome and of the lid recess result in a rigid structure integrated into the lid, by which structure the applied clip-on force effectively clips on the lid without significant buckling of the lid.
- the clipped on lid markedly stiffens the opening area of the receptacle resulting in excellent spill-proofness and good leakage-proofness as well.
- a particularly important aspect of the invention is a circumferentially continuously operating hinge mechanism integrated into the lid. This allows to easily clip-on the lid, in practice by a quick grasp of the hand. As soon as pressure is applied at least on the dome top wall, the dome is lowered, the dislocated inner leg wall tilts the U-web downwardly about the hinge formed at the transition between the U-web and the outer leg wall as soon as the resistance to movement of the constriction over the bead starts to increase. The tilting movement of the U-web temporarily tends to pull the outer leg wall away from the inner wall of the receptacle. The contact between the bead and the constriction tilts the constriction outwards and the clamping groove diverges somewhat.
- the bead Due to the clip-on pressure or, if necessary, by automatically also or alternatively pressing on the outer lid periphery when the dome is pushed downwardly, the bead passes the constriction easily and in one go.
- the hinge mechanism re-establishes the fit of the lid, i.e., the U-web returns into a position essentially perpendicular to the axis of the lid and firmly holds the outer leg wall against the inner wall of the receptacle.
- the constriction is returned behind the bead until the bead is in a tight and hermetically sealed force fit in the clamping groove.
- the upwardly protruding dome allows to actuate the joint mechanisms by first lowering the dome relative to the clamping groove and to open the clamping groove before the bead slips through. Then the dome returns into its initial elevated position. During clip-on the dome top wall may be lowered by the applied pressure until the palm of the hand assists at the lid periphery to easily complete the clip-on action.
- the bead of the receptacle can be formed as a curled bead or a full rolled rim, or a partially curled bead or half rolled rim, or instead as an outwardly bent edge flange.
- An easy and comfortable clip-on action of the lid is achieved in any case, resulting in the final leakage-proofness and the stable lid holding effect.
- One lid design fits many bead designs.
- the lid is designed in view to an optimised and easy clip-on action, despite a powerful force fit in the clipped on condition. Thanks to its shape the lid is relatively stiff in its central region such that the bead easily and completely can be clipped-in the clamping groove into a tight form fit and force fit just by pressing in clip-on direction, assisted by the guidance of the guide projection, and by temporarily opening the clamping groove by a movement of the dome relative to the constriction.
- the U-web extends substantially planar and substantially perpendicularly to the lid axis, and that the inner leg wall is substantially parallel to the lid axis. Due to those structural features the integral hinge mechanism is acting well when downward pressure is applied on the lid, mainly since for mechanical reasons the inner leg wall behaves more rigid than the outer leg wall when the U-web is tilted such that consequently the outer leg wall has to yield inwards and then temporarily opens the clamping groove from the inner side.
- the outer diameter of the outer surface should correspond, at the height position of the constriction, at least approximately to the inner diameter of the receptacle wall in the opening area so that the centring and guide effect already starts before the bead reaches the constriction.
- the bead snaps into the clamping groove, especially the softer material of the receptacle will yield in the bead and in the receptacle wall so that a strong positive engagement will be established, when the lid is clipped-on.
- the outer leg wall of the lid recess may slightly yield inwards, as a consequence of the contact pressure between the outer surface and the receptacle wall.
- the outer diameter of the outer surface in the clamping groove even may be markedly larger than the inner diameter of the receptacle wall in the opening area, i.e. where the inner wall curves outwardly into the bead. This measure guarantees that during the whole movement of the bead past the constriction into the clamping groove a significant guidance and centring will take place.
- the lid may be clipped-on by mere application of pressure substantially only on the dome.
- the outer surface may have at least 2.5 times the height of the clamping groove. Providing 3 times the height, or even 4 times the height of the clamping groove may be still better. It is to be noted that, due to the pressure between the outer surface and the receptacle wall and by a large contact area an extremely effective sealing effect will result complementary to the sealing effect of the bead in the clamping groove.
- a cone angle between approx. 6° and 12° i.e. an overall cone angle between approx. 12° and 24°, may be expedient.
- a preferred angle range amounts to between approx. 8° and 10°, i.e. between approx. 16° and 20° in total.
- depressions formed where the top of the dome top wall merges with the outer dome wall facilitate the easy clip-on action of the lid and increase the rigidity of the dome. Furthermore, the depressions provide visual clues where to apply the fingers and define gripping spots for comfortably removing the lid from a lid-stack. Undercut depressions do not only provide a hand grip, but even may define lid stacking shoulders. Each lid may only rest with the shoulders of the depressions on the dome top wall of the next lid such that the lids in the stack can not get jammed.
- the radial thickness of the bead should be larger than the radial interior width of the clamping groove.
- the radial thickness of the bead should be between 10% and 20%, preferably approx. 15%, larger than the average radial interior width of the clamping groove. This dimensioning results in a good sealing effect and, simultaneously, only moderate forces will be necessary for clipping the lid onto the receptacle.
- the radial interior width of the clamping groove may decrease in a direction opposite to the clip-on direction; expediently with the cone angle of the receptacle wall.
- the clamping groove will, in this way, produce a wedge effect until the bead finally settles in position.
- At least one belt-like zone with an increased coefficient of friction ought to be provided at the outer surface of the outer leg wall and/or at the inner wall of the receptacle. This might result in an increased friction engagement between the lid and the receptacle and a stiff cup opening region.
- the constriction may consist of successive deeper and shallower depressions formed from the exterior.
- the deeper depressions are longer in circumferential direction than the shallower depressions. This facilitates the clip-on action but results in a stable and durable holding effect, and stiffens the lid periphery.
- a plurality of upwardly protruding beverage distinguishing protrusions in the dome top wall may be provided to allow identification of the type of liquid from outside, e.g. coke, diet coke, orange juice, etc.
- the protrusions may be push-in buttons.
- a further generally important aspect is a penetration region formed in the dome top wall.
- This region may have a thinner wall thickness than at least the dome top wall, and has intersecting score lines through which a straw comfortably may be introduced by breaking the score lines.
- the reduced wall thickness allows to insert the straw more easily.
- the reduced wall thickness may be produced by locally compressing the material of the lid.
- the region with reduced wall thickness is particularly useful for a relatively stiff lid having a somewhat thicker wall than such conventional lids. Providing the thinner region, however, is of general advantage for all such lids, because this measure generally facilitates the introduction of a straw.
- the penetration region for introducing a straw expediently is provided at the bottom of a recess e.g. located in the centre of the dome top wall.
- the reduced bottom wall thickness increases the rigidity of the dome in view to the easy clip-on action.
- the penetration region may be curved inwardly to facilitate the introduction of a straw and to increase the resistance against buckling outwards by liquid pressure.
- the curvature also leads to an automatic closing effect of the broken score lines after the straw is withdrawn and when liquid pressure acts from inside on the flaps defined by the broken score lines.
- a contour of the recess corresponding to two ellipses the main axes of which are offset to each other by 90° increases the rigidity of the dome and offers an attractive appearance of the dome design.
- the score lines expediently are formed along the main axes of both ellipses. It might suffice to have only a thin walled core portion of the bottom instead to facilitate the introduction of a straw.
- a further important aspect of the invention is directed to an easy clip-on lid for a conical double wall paper or cardboard receptacle.
- Double wall paper or cardboard receptacles conventionally, have an opening area where the inner receptacle wall is deformed outwardly at a step and is connected with the outer receptacle wall. The bead is formed on the upper end of the inner receptacle wall.
- the cone angle of the conical inner wall of the double wall receptacle is bigger below the widened upper opening area which forms a continuation of the lower receptacle wall by a circumferential shoulder and has a smaller or even zero cone angle than the lower receptacle wall.
- the lid placed on the bead already contacts the widened opening area inner wall by the centring and guide cone when the bead reaches contact with the constriction.
- the lid is centred and guided over the bead.
- the centring and guide projection is pulled inwardly due to the deformation taking place between the pressed down dome and the clamping groove such that the bead more easily passes the constriction.
- the lid when clipped-on, provides high leakageproofness and stiffness in the receptacle opening region.

Abstract
Description
- The present invention relates to a cup-shaped receptacle and to a lid for such a receptacle.
- Of the clip-on plastic lid on the cup-shaped receptacle in
US 5,253,781 A , the outer surface of the outer leg wall of the lid recess extends downwards just slightly beyond the height position of the constriction. The cone angle and the outer diameter of the outer surface are matched with the cone angle and the inner diameter of the receptacle wall such that outer surface does not get in significant contact with the receptacle wall even when the bead of the receptacle, which is implemented as a curled rim, fully is seated on the clamping groove. Due to the comparatively short outer surface and the large radial dimension of the U-web of the lid recess, the clamping groove tilts inwards during the clip-on movement; this hinders the bead to smoothly move over the whole circumferential length past the constriction. It is necessary to first manually centre the lid with the clamping groove neatly on the bead and then to clip on the lid by pressure directly acting on the upper wall of the clamping groove with a sliding rotating movement of the hand. This clip on action is troublesome, time-consuming and increases the risk that the bead does not properly snap into the clamping groove at some locations along the circumference of the cup opening. This has the effect that liquid may leak through when the full cup is tilted. The lid easily pops off inadvertently if the full receptacle falls over, because the cup opening region easily gets deformed radially. - It is an object of the present invention to provide a receptacle as well as a lid which is suitable for said receptacle, by means of which an easy clip-on action of the lid can be achieved, even by unskilled persons, such that the clipped on lid provides leakage-proofness and hardly pops off when the full cup falls over. Even though the invention intends to achieve a high lid holding force and perfect tightness, the lid ought to be clipped on easily.
- Since, according to the invention, the outer leg wall has a relatively long downward extension, the U-web of the lid recess, and the inner leg wall commonly constitute a rigid centring and guide projection which slidingly contacts the receptacle wall at least already while the bead moves past the constriction. The clamping groove automatically is precisely centred on the bead, and the bead is clipped-on virtually at one go and along its whole circumferential length, past the constriction into the clamping groove by applying pressure essentially only on the dome top wall. The sliding contact between the outer surface and the receptacle wall guides the constriction uniformly over the bead, since thanks to guidance and centring, the bead generates uniform resistance against the lid downward movement everywhere. The guiding projection converts the pressure applied to the dome into a downwardly oriented pulling force uniformly distributed along the constriction to pull the constriction uniformly past the bead, until the bead is correctly positioned in the clamping groove. This advantageous effect of the centring and guide projection, which actually is a cone or a cylinder, and the uniform force transmission, in co-action allow to provide a strong force fit between the bead and the clamping groove, said force fit resulting from a relatively narrow dimensioning between the bead and the clamping groove and the given elasticity. This assures that the clipped on lid prevents leakage, and that the bead does not even locally leave the clamping groove if the full cup falls over. The shape of the dome and of the lid recess result in a rigid structure integrated into the lid, by which structure the applied clip-on force effectively clips on the lid without significant buckling of the lid. The clipped on lid markedly stiffens the opening area of the receptacle resulting in excellent spill-proofness and good leakage-proofness as well.
- A particularly important aspect of the invention is a circumferentially continuously operating hinge mechanism integrated into the lid. This allows to easily clip-on the lid, in practice by a quick grasp of the hand. As soon as pressure is applied at least on the dome top wall, the dome is lowered, the dislocated inner leg wall tilts the U-web downwardly about the hinge formed at the transition between the U-web and the outer leg wall as soon as the resistance to movement of the constriction over the bead starts to increase. The tilting movement of the U-web temporarily tends to pull the outer leg wall away from the inner wall of the receptacle. The contact between the bead and the constriction tilts the constriction outwards and the clamping groove diverges somewhat. Due to the clip-on pressure or, if necessary, by automatically also or alternatively pressing on the outer lid periphery when the dome is pushed downwardly, the bead passes the constriction easily and in one go. When the pressure ceases, the hinge mechanism re-establishes the fit of the lid, i.e., the U-web returns into a position essentially perpendicular to the axis of the lid and firmly holds the outer leg wall against the inner wall of the receptacle. The constriction is returned behind the bead until the bead is in a tight and hermetically sealed force fit in the clamping groove. The upwardly protruding dome allows to actuate the joint mechanisms by first lowering the dome relative to the clamping groove and to open the clamping groove before the bead slips through. Then the dome returns into its initial elevated position. During clip-on the dome top wall may be lowered by the applied pressure until the palm of the hand assists at the lid periphery to easily complete the clip-on action.
- The bead of the receptacle can be formed as a curled bead or a full rolled rim, or a partially curled bead or half rolled rim, or instead as an outwardly bent edge flange. An easy and comfortable clip-on action of the lid is achieved in any case, resulting in the final leakage-proofness and the stable lid holding effect. One lid design fits many bead designs.
- The lid is designed in view to an optimised and easy clip-on action, despite a powerful force fit in the clipped on condition. Thanks to its shape the lid is relatively stiff in its central region such that the bead easily and completely can be clipped-in the clamping groove into a tight form fit and force fit just by pressing in clip-on direction, assisted by the guidance of the guide projection, and by temporarily opening the clamping groove by a movement of the dome relative to the constriction.
- For this function it may be important that the U-web extends substantially planar and substantially perpendicularly to the lid axis, and that the inner leg wall is substantially parallel to the lid axis. Due to those structural features the integral hinge mechanism is acting well when downward pressure is applied on the lid, mainly since for mechanical reasons the inner leg wall behaves more rigid than the outer leg wall when the U-web is tilted such that consequently the outer leg wall has to yield inwards and then temporarily opens the clamping groove from the inner side.
- It may be expedient when the outer surface slidingly co-operates with the receptacle wall already before the bead starts to deform the constriction elastically. This has the effect that the clamping groove and the constriction, respectively, are put over the bead at a neatly centred position so that the bead will have to overcome essentially the same resistance to passage over its whole circumferential length and therefore easily and uniformly is clipped into the clamping groove.
- When the cone angles of the outer surface and of the receptacle wall are approximately identical, the outer diameter of the outer surface should correspond, at the height position of the constriction, at least approximately to the inner diameter of the receptacle wall in the opening area so that the centring and guide effect already starts before the bead reaches the constriction. When the bead snaps into the clamping groove, especially the softer material of the receptacle will yield in the bead and in the receptacle wall so that a strong positive engagement will be established, when the lid is clipped-on. Additively or alternatively, also the outer leg wall of the lid recess may slightly yield inwards, as a consequence of the contact pressure between the outer surface and the receptacle wall.
- The outer diameter of the outer surface in the clamping groove even may be markedly larger than the inner diameter of the receptacle wall in the opening area, i.e. where the inner wall curves outwardly into the bead. This measure guarantees that during the whole movement of the bead past the constriction into the clamping groove a significant guidance and centring will take place. A diameter oversize of approx. 3.5%, i.e. in a range between approx. 1.5% and 5%, depending on the size of the receptacle, may be expedient.
- A markedly downward extension of the outer surface beyond the height position of the constriction is important for the intended centring and guiding effect. The lid may be clipped-on by mere application of pressure substantially only on the dome. The outer surface may have at least 2.5 times the height of the clamping groove. Providing 3 times the height, or even 4 times the height of the clamping groove may be still better. It is to be noted that, due to the pressure between the outer surface and the receptacle wall and by a large contact area an extremely effective sealing effect will result complementary to the sealing effect of the bead in the clamping groove.
- A cone angle between approx. 6° and 12°, i.e. an overall cone angle between approx. 12° and 24°, may be expedient. A preferred angle range amounts to between approx. 8° and 10°, i.e. between approx. 16° and 20° in total.
- Depressions formed where the top of the dome top wall merges with the outer dome wall facilitate the easy clip-on action of the lid and increase the rigidity of the dome. Furthermore, the depressions provide visual clues where to apply the fingers and define gripping spots for comfortably removing the lid from a lid-stack. Undercut depressions do not only provide a hand grip, but even may define lid stacking shoulders. Each lid may only rest with the shoulders of the depressions on the dome top wall of the next lid such that the lids in the stack can not get jammed.
- In order to achieve the strong force fit between the bead and the clamping groove, which is important for the sealing effect, the radial thickness of the bead should be larger than the radial interior width of the clamping groove. The soft paper or paperboard material of the receptacle and the material of the bead, respectively, yield on the inner side and on the outer side as soon as the bead is seated in the clamping groove. Squashed zones with planar contact areas, i.e. not only line contacts, result in an improved sealing effect.
- The radial thickness of the bead should be between 10% and 20%, preferably approx. 15%, larger than the average radial interior width of the clamping groove. This dimensioning results in a good sealing effect and, simultaneously, only moderate forces will be necessary for clipping the lid onto the receptacle.
- In order to enhance the holding effect of the lid on the bead and to gradually squash the material, the radial interior width of the clamping groove may decrease in a direction opposite to the clip-on direction; expediently with the cone angle of the receptacle wall. The clamping groove will, in this way, produce a wedge effect until the bead finally settles in position.
- In order to improve the holding effect for the clip-on lid at least one belt-like zone with an increased coefficient of friction ought to be provided at the outer surface of the outer leg wall and/or at the inner wall of the receptacle. This might result in an increased friction engagement between the lid and the receptacle and a stiff cup opening region.
- A further important aspect of the invention is that the constriction may consist of successive deeper and shallower depressions formed from the exterior. Preferably, the deeper depressions are longer in circumferential direction than the shallower depressions. This facilitates the clip-on action but results in a stable and durable holding effect, and stiffens the lid periphery.
- A plurality of upwardly protruding beverage distinguishing protrusions in the dome top wall may be provided to allow identification of the type of liquid from outside, e.g. coke, diet coke, orange juice, etc. The protrusions may be push-in buttons.
- A further generally important aspect is a penetration region formed in the dome top wall. This region may have a thinner wall thickness than at least the dome top wall, and has intersecting score lines through which a straw comfortably may be introduced by breaking the score lines. The reduced wall thickness allows to insert the straw more easily. The reduced wall thickness may be produced by locally compressing the material of the lid. The region with reduced wall thickness is particularly useful for a relatively stiff lid having a somewhat thicker wall than such conventional lids. Providing the thinner region, however, is of general advantage for all such lids, because this measure generally facilitates the introduction of a straw.
- The penetration region for introducing a straw expediently is provided at the bottom of a recess e.g. located in the centre of the dome top wall. The reduced bottom wall thickness increases the rigidity of the dome in view to the easy clip-on action.
- The penetration region may be curved inwardly to facilitate the introduction of a straw and to increase the resistance against buckling outwards by liquid pressure. The curvature also leads to an automatic closing effect of the broken score lines after the straw is withdrawn and when liquid pressure acts from inside on the flaps defined by the broken score lines. A contour of the recess corresponding to two ellipses the main axes of which are offset to each other by 90° increases the rigidity of the dome and offers an attractive appearance of the dome design. The score lines expediently are formed along the main axes of both ellipses. It might suffice to have only a thin walled core portion of the bottom instead to facilitate the introduction of a straw.
- A further important aspect of the invention is directed to an easy clip-on lid for a conical double wall paper or cardboard receptacle. Double wall paper or cardboard receptacles, conventionally, have an opening area where the inner receptacle wall is deformed outwardly at a step and is connected with the outer receptacle wall. The bead is formed on the upper end of the inner receptacle wall. The cone angle of the conical inner wall of the double wall receptacle is bigger below the widened upper opening area which forms a continuation of the lower receptacle wall by a circumferential shoulder and has a smaller or even zero cone angle than the lower receptacle wall. The lid placed on the bead already contacts the widened opening area inner wall by the centring and guide cone when the bead reaches contact with the constriction. During the clip-on action the lid is centred and guided over the bead. The centring and guide projection is pulled inwardly due to the deformation taking place between the pressed down dome and the clamping groove such that the bead more easily passes the constriction. The lid, when clipped-on, provides high leakageproofness and stiffness in the receptacle opening region.
- Expediently, the cone angle of the outer surface or the centring and guide projection either may be zero or has a value which is smaller than the angle value of the cone angle of the receptacle inner wall. The rigid centring and guide projection forces the bead into a leakageproof seated condition in the clamping groove and even may cause a deformation of the opening area of the double wall receptacle for intensified receptacle rim portion stiffening and sealing purposes.
- The centring and guide projection, in this case, ought to be continued downwardly by an inward stepped portion of the outer leg wall dimensioned for a press-fit co-action with the receptacle wall. The inwardly stepped portion should have a cone angle essentially equal to the cone angle of the inner receptacle wall below the upper stepped opening area. The co-action between the stepped portion and the receptacle inner wall provides an intensified sealing effect even deep inside the receptacle.

The lid is adapted to be clipped on anopening area 9 of the receptacle C such that said receptacle C is closed in a leakage-free manner and such that the lid D will not come off, not even if the full receptacle C falls over. The lid D (Fig. 1 ) is provided with a peripheral, circumferentiallycontinuous clamping groove 1, above the plane of which adome 2 vaults on the inner side of the clampinggroove 1. Thedome 2 is separated from the clampinggroove 1 by a circumferential substantially uniform lid recess V and is provided with an essentially planar dometop wall 5 and several circumferentially distributeddepressions 3. Relative to the clampinggroove 1, anouter leg wall 4 of a lid recess V (Fig. 2 ) extends markedly downwards beyond the plane of the clampinggroove 1. - The lid D (
Fig. 2 ) is clipped onto theopening area 9 of the receptacle C (Fig. 3 ) by applying pressure R e.g. only on the dometop wall 5 in clip-on direction. The dometop wall 5 extends essentially parallel to the plane of the lid D. The lid recess V has a U-shaped cross-section and concentrically surrounds thedome 2. The lid recess V is bound by theouter leg wall 4, which in this embodiment tapers conically downwards, alower U-web 22, and aninner leg wall 23 which forms an upwardly extending outer dome wall. Theouter leg wall 4 has anouter surface 6 which extends into the clampinggroove 1. Theouter surface 6 is arranged at a conical angle α/2, which may correspond at least essentially to the conical angle α/2 of areceptacle wall 7 of the receptacle C. - At the lower end of the
receptacle wall 7 inFig. 3 , a receptacle bottom 8 is arranged, whereas theopening area 9 of the receptacle is delimited by thereceptacle wall 7 and an outwardly projectingbead 10, preferably a so-called curledrim 11 consisting of the paperboard or paper material of the receptacle C. In the case of a plastic receptacle, thebead 10 may also be produced by injection moulding. The bead instead may be only a half curled bead or an outwardly projecting receptacle rim flange. -
Fig. 4 shows the lid D on thebead 10, which is formed as a curledrim 11. Aconstriction 14 of the lid D rests on thebead 10. - The
outer leg wall 4 is continued, at the upper end by awall 12 which extends approximately parallel to the plane of the lid and by acircumferential apron 13. Theapron 13 extends approximately parallel to the axis of the lid D down to theconstriction 14. Theconstriction 14 may be a scorelike depression from the outside and forms an interiorrounded crest 15. Thecrest 15 and theconstriction 14 can be continuous in circumferential direction, or alternatively can be formed by individual local depressions between which (indicated by broken lines) the outer contour approximately continues. Theconstriction 14 is continued downwardly by an outwardlyinclined wall 16 defining a clip-onramp 17. Fromwall 16, afurther apron 18 extends downwards, terminating at anexterior flange 19. The height of thefurther apron 18 could be shorter than shown. - The radial thickness Y of the
bead 10, measured at the transition from thestraight receptacle wall 7 to the curvature of thebead 10, may be larger than the radial interior width Y1 of the clampinggroove 1. The radial thickness Y may exceed the interior width Y1 by 10% to 20%, preferably by approx. 15%. In the clampinggroove 1 the radial interior width Y1 gradually decreases, preferably with the cone angle α/2 from theconstriction 14 towards thewall 12. - The clamping
groove 1 defines a length L between thecrest 15 and the inner side of thewall 12. Theouter leg wall 4 extends downwards beyond the height position of theconstriction 14 by a length L1 which may be equal to at least 2.5 times the height L, preferably 3 times, and even more preferably 4 times the height L or more. - The outer diameter D1 of the
outer surface 6 of theouter leg wall 4 at the height position of the constriction 14 (e.g. the crest 15) at least largely corresponds to the interior diameter D7 of thereceptacle wall 7 at thebead 10, i.e. at the transition from thestraight receptacle wall 7 to the outwardly directed curvature of thebead 10. The outer diameter D2 of theouter surface 6 of theouter leg wall 4 at the junction withwall 12 is even markedly larger than the interior diameter D7, preferably by approx. 1.5% to 5.0%, preferably by approx. 3.5%. - When pressure R is applied on the
dome 2 inFig. 4 theouter surface 6 already slidingly contacts thereceptacle wall 7 before or as soon as thebead 10 reaches theconstriction 14. The lid recess V forms a centring and guide projection K which supports and facilitates the easy clip-on operation of the lid D. It will be expedient when the sliding contact is established even before thebead 10 reaches theconstriction 14. When the lid D is pressed down still further, thebead 10 will deform theconstriction 14 elastically outwards; in the course of this process, also thebead 10 is slightly deformed before it moves over thecrest 15 and snaps into the clamping groove 1 (Fig. 5 ). The criss-cross hatched regions shown inFig. 5 indicate squeezedareas bead 10 and thereceptacle wall 7, to promote the sealing, the holding and the stiffening effects. Alternatively or additively, also theouter leg wall 4 may slightly yield inwards (indicated in broken lines at 21'). - The lid D in
Figs 6 to 10 differs from the lid D ofFigs 1 to 5 by a modified design of theconstriction 14 and by arecess 24 in the dometop wall 5. The constriction 14 (Fig. 7 ) is formed by alternating successive deeper and shallower depressions 16a, 16b. The depressions 16a, 16b form a snake line shaped inner crest 15'. The deeper depressions 16a may be longer in circumferential direction than the shallower depressions 16b. Furthermore,Fig. 7 shows by dotted line 19' a shortenedapron 18. - In
Fig. 6 therecess 24 has abottom dome region 25 of limited size substantially parallel to and situated below the dometop wall 5. The wall thickness x of the lid D is substantially constant. Only theregion 25 is thinner (thickness x 1), e.g. by compressing the material. Theregion 25 is situated in the centre of the dometop wall 5. For introducing a straw theregion 25 is formed with crossing breakable score lines 26. Expediently, theregion 25 may be curved towards the inner side of thedome 2. - The
depressions 3 in the transition from the dometop wall 5 to theinner leg wall 23 increase the rigidity of thedome 2 and allow to grip the lid D by the finger tips, e.g. in order to more easily remove the lid D from a stack of lids, and to put the lid D on the receptacle C. The clip-on force R even may be applied via thedepressions 3 on the dome. However, preferably the easy clip-on action may be carried out by pressing the palm of the hand on the even dometop wall 5. - In
Fig. 6 theouter leg wall 4 may have at least onebeltlike circumferential zone 30 in which the coefficient of friction is increased in order to achieve an intensified holding effect as soon as the lid D is clipped-on. Thezone 30 may be situated higher than shown, or may be narrower or wider. A respective zone with an increased coefficient of friction also could be provided at thereceptacle wall 7, either instead ofzone 30 at the lid, or in co-action with thezone 30 provided at the lid D. - A circumferentially continuous hinge mechanism M is integrated into the lid D by the design and the shape of the
dome 2 and the lid recess V. The hinge mechanism may assist in clipping-on the lid D, as particularly shown inFigs 6 to 10 . - The hinge mechanism M of the lid D consists of the
dome 2, theinner leg wall 23, theU-web 22, and theouter leg wall 4. The transitions of theouter leg wall 4 intoU-web 22 and ofU-web 22 intoinner leg wall 23 define hinges 29. Theinner leg wall 23 extends essentially parallel to the longitudinal axis of the lid, while theU-web 22 is planar and perpendicular to the lid axis. It is to be noted that due to the rigidity of thedome 2 and due to the smaller diameter of theinner leg wall 23 in relation to the bigger diameter of theouter leg wall 4, the outer leg wall will yield inwardly easier than theinner leg wall 23. This effect is used to temporarily open the clampinggroove 1 and to achieve an easy lid clip-on action. - In
Fig. 8 the lid D is put on thebead 10 of the receptacle C such that the entire circumferential extension of theconstriction 14 will become is centred on thebead 10. Theouter leg wall 4 contacts thereceptacle wall 7. Now a clip-on force R is applied e.g. to the dometop wall 5, e.g. by the flat hand until the dometop wall 5 lowers (Fig. 9 ). - In
Fig. 9 a reaction force R' acts counter to the clip-on force R, since theconstriction 14 seats on thebead 10. Theinner leg wall 23 tilts the U-web 22 downwards by theinner hinge 29 at the transition from theinner leg wall 23 into theU-web 22. Thanks to the radial rigidity of thedome 2 the tilting of the U-web 22 results in aforce 28 acting at theouter hinge 29. Theforce 20 relieves theouter leg wall 4 from thereceptacle wall 7 such that even the clampinggroove 1 may open somewhat at the inner side. Theapron 18 is displaced outwards in the direction of an arrow 27 by the reaction force R', such that even the clampinggroove 1 temporarily may open somewhat at the outer side. Under the clip-on force R, and, because dometop wall 5 is lowered, by then possibly also pressing on thewall 12, thebead 10 slides past theconstriction 14 until it finally snugly is clipped into the clampinggroove 1. - In
Fig. 10 the clip- on force R has ceased. The U-web 22 returned by elasticity into the orientation essentially perpendicular to the lid axis and presses theouter leg wall 4 against thereceptacle wall 7. The apron 8 also returned by elasticity. The clampinggroove 1 firmly holds thebead 10. The centring projection K and the clampinggroove 1 both significantly stiffen the opening portion of the receptacle C. - In
Fig. 11 therecess 24 has a wall contour like a four leaves clover, i.e. a contour which may be characterised by two equally sized ellipses the main axes of which are offset by 90°. The score lines 26, in theregion 25 extend along the main axes of both ellipses.Fig. 12 shows the difference between the wall thickness x and the wall thickness X1 inregion 25 in exaggerated scale. Theregion 25 may be curved inwardly, as shown, or may be parallel to the dometop wall 5. The reduced wall thickness x1 is not needed for theentire region 25. It could suffice to provide only a thin walled central portion of theregion 25, e.g. by compressing the material when producing the lid D. - The radial width of the annular U-web 22 in
Figs 6 to 10 may amount to about 10% of the outer diameter of the lid D, while the diameter of the dometop wall 5 may amount to about 60% of the outer diameter of the lid D. - The embodiment of the lid D of
Figs 13 and 14 is similar to the embodiment ofFigs 6 to 12 but additionally is provided with regularly distributedbeverage distinguishing protrusions 5a in the dometop wall 5. There are, e.g., four ovalbeverage distinguishing protrusions 5a, each having a marking and/or a pushable button in its top. This is standard equipment of many lids on the market. Theprotrusions 5a are located with a small radial distance from the outer edge of the dometop wall 5 and also with a small radial distance from thecentral recess 24. Furthermore, thedepressions 3 are made undercut such that they may be gripped more easily by the finger tips when the lid D has to be removed from a stack of several lids (as shown inFig. 15 ). Eachdepression 3 may define alateral shoulder 3a which may serve as a stacking stop as shown inFig. 15 such thatshoulder 3a rests on the dometop wall 5 of the next lid D of the stack. Theshoulder 3a expediently prevents that the stacked lids get jammed within each other, because the stacked lids contact each other mainly where theshoulders 3a rest on the dometop wall 5 and where the outer leg walls contact each other. This feature results in an orderly and dense stack from which each lid D can be removed comfortably. In the embodiment shown, eightdepressions 3 are provided. - The lid D of
Figs 13 to 15 also has the centring and guide projection K (a guide cone) and the hinge mechanism M for facilitating the clip-on action. -
Figs 16 and17 show an easy clip-on lid D for a double wall receptacle CD. The double wall receptacle CD has aninner wall 7 and an outer wall 7c with an air gap in-between to provide a thermal insulating effect. Thebead 10 is formed at the upper end of theinner wall 7. The double wall receptacle CD first is formed with a cone angle α/2 which continues to thebead 10. During the forming process the upper part of theinner wall 7 is widened outwards such that theopening area 9a results where the cone angle α'/2 is smaller than the cone angle α/2, or even almost zero, and such that ashoulder 7b is formed. The lid D for the double wall receptacle CD has the already described centring and guide projection K. In this case the projection K is formed such that theouter surface 6 either is cylindrical (as shown) or has a small cone angle β/2 between 0° (cylindrical) or a value similar but smaller than the cone angle α'/2. Theouter surface 6 or theouter leg wall 4 is continued by an inwardly steppedwall portion 4b such that ashoulder 4a is formed. The outer surface portion 6a ofwall portion 4b is inclined with cone angle α/2. The bottom of the centring and guide projection K is formed by the U-web 22 which extends substantially perpendicular to the central lid axis. The diameter D1 of theouter surface 6 corresponds essentially to the diameter D7 of theopening area 9a in the region of thebead 10. In theopening area 9a inner parts of theinner receptacle wall 7a and outer parts of theouter leg wall 4 and thewall portion 4b are indicated to be deformed or to get into intimate pressure contact when the lid D is fully clipped-on the double wall receptacle CD. - In
Fig. 16 the lid D is centred on the double wall receptacle CD such that thebead 10 has approached theconstriction 14 from below. Then theouter surface 6 already contacts theinner receptacle wall 7a in theopening area 9a to properly centre and guide the lid D when the clip-on pressure R is applied e.g. on the dome top wall 5 (not shown inFig. 16 ). - While the clip-on pressure forces the
constriction 14 over thebead 10, theouter surface 6 is guiding the lid D. When theU-web 22 is tilted downwardly, as already explained above, theouter leg wall 4 is somewhat dislocated inwardly, while theconstriction 14 yields outwardly. This facilitates that theconstriction 14 easily slips over thebead 10 until the position ofFig. 17 is reached. Thebead 10 then is gripped from the outer side and the inner side. The contacting wall parts (20 and 20') may become squeezed. Theshoulder 4a either is seated on theshoulder 7b or at least is close toshoulder 7b. A particular contact pressure is achieved in the region 20' resulting in an additional sealing effect in addition to the sealing effect achieved by the co-action between the clampinggroove 1 and thebead 10 and between theouter leg wall 4 and the innerreceptacle wall portion 7a. InFig. 17 , the rigid dome structure of the lid D even may force the innerreceptacle wall portion 7a into a parallel relationship to theouter leg wall 4 resulting in a high holding force and an excellent effect and a markedly stiffened opening portion of the closed receptacle CD. - Additionally, the co-action between the
shoulders shoulders bead 10 and the clampinggroove 1 in a preloaded closing condition characterised by high leakage-proofness and high holding force for the lid D. -
Fig. 18 is a sectional view of clipped-on lid D on one-wall receptacle C, similar toFig. 5 .Bead 10 is fully curled inwards. Clampinggroove 1 of the lid D is of round cross-section. The criss-cross hatched areas represent zones of strong contact, e.g. of even slightly squeezed surface portions. There is tight contact between the clampinggroove 1 and thebead 10 over more than 180° of the circumference of thebead 10. Theouter leg wall 4 significantly stiffens the upper opening region against radial deformation.
