Abstract

A cup-shaped receptacle (c) has an outer bead (10) in its opening area for clipping on a plastic lid (D). The lid has a circumferentially continous clamping groove (1) for receiving the bead. The clamping groove is continued outwards by an elastically deformable constriction (14), and inwards by an outer wall ( 6) of a circumferentially continuous, U-shaped lid recess, the U-web (22) of which is situated below the height position of the constriction and the inner leg wall (23) of which forms a part of a dome (2) wall of a dome which extends upwardly beyond the height position of the constriction. The lid recess extends downwards beyond the height position of the constriction and has an outer diameter at its outer surface which is adapted to the inner diameter of the receptacle wall such that the lid recess functions at least as a centring and guide projection for the lid-clip-on action, which projection slidingly co-operates with the receptacle wall already at least while the bead passes the constriction.

Description

Cup-shaped receptacle and lid

Technical field

The present invention relates to cup-shaped receptacle and the lid that is used for such container.

Background technology

For U.S. Patent No. 5,253, folder following formula (clip-on) vinyl cover on the cup-shaped receptacle among 781 A, the outside face of the outer leg wall of lid depression extends the height and position just over compression piece downwards.The cone angle of the cone angle of outside face and external diameter and wall of container and inside face are arranged in clamping slot to coupling fully even work as the crimping (it is implemented as the edge of rolling) of container like this, and outside face does not significantly contact with wall of container yet.Because the relatively short outside face of the U-shaped sheet metal of lid depression and bigger radial dimension, clamping slot slopes inwardly in the process of motion on folder; This has stoped crimping to move reposefully on whole circumferential lengths by compression piece.This is just must be at first manual to be registered to the clamping slot that is positioned at dexterously on the crimping with lid, rotatablely moves with the slip of hand then and presss from both sides the above lid by the pressure on the upper wall that directly affacts clamping slot.This folding action is a trouble, and is consuming time and increased crimping in the danger that does not suitably snap in the clamping slot on some positions of the girth of cup-shaped openings.This effect that has is that liquid may leak when whole cup tilts.If entire container overturning, described lid are easy to be not intended to flick, because the cover gab zone is easy to radial deformation.

Summary of the invention

The lid that the purpose of this invention is to provide a kind of container and be suitable for described container, by described container, even unskilled people operates on the folder that also can be easy to realize covering, the lid that is clipped on like this provides and has prevented from leakage function and be difficult to when entire container goes over to flick.Even the invention is intended to realize higher lid confining force and compactness in working order, described lid must be clipped on easily.

According to the present invention, because outer leg wall has relatively long downward extension, the U-shaped sheet metal of lid depression and interior leg wall constitute rigidity centering and guide hump usually, and when crimping was by compression piece, described projection contacted with the wall of container that has existed slidably at least.Clamping slot is accurately felt relieved on crimping automatically, and described crimping almost presss from both sides quickly and along its whole circumferential lengths, by only pressure being applied on the dome top wall basically compression piece is passed through in the clamping slot.Moving contact between outside face and the wall of container evenly guides compression piece on crimping, because guiding and centering, every place of the lid that crimping moves downward relatively produces uniform resistance.The pressure that guide hump will be applied to the top is converted to along compression piece and is orientated the well-distributed pulling force downwards, with the pulling compression piece evenly by crimping, until crimping correct location in clamping slot.Be actually this advantageous effects and the uniform force cooperative transmission of taper or columniform centering and guide hump, cooperate with the power that allows to provide stronger between crimping and clamping slot, described power cooperates because the size of the relative narrower between crimping and the clamping slot and given elasticity cause.This has guaranteed that the lid on the folder can prevent to leak, and if whole cup overturning crimping almost do not leave clamping slot in the part.The shape of top and lid depression forms the rigid construction that is integrated in the lid, and power is clipped in effectively and covers on the folder that applies by described structure cup, and crooked described lid significantly not.The lid that is caught on makes the open area hardening of container significantly, produces good anti-spilled and leakage prevention capability preferably.

The one side of particular importance of the present invention is to be integrated into the circumferential continuous handling linkage that covers.This allows to be easy to press from both sides loam cake, is to catch rapidly by hand in practice.As long as pressure is applied on the dome top wall at least, the top is lowered, when the resistance that move of compression piece on crimping begins to increase, the hinge that the interior leg wall of dislocation forms on the transition portion that is formed between U-shaped sheet metal and the outer leg wall has a down dip the U-shaped sheet metal is past.The banking motion of U-shaped sheet metal temporarily is tending towards outer leg wall is pulled out from the inwall of container.Contact between crimping and the compression piece is outward-dipping with compression piece, and clamping slot has certain bifurcated.When the top down promotes because the folder upward pressure, perhaps if necessary also automatically by or be expressed to alternatively around the enclosing cover, crimping is easy to and passes through compression piece quickly.When the pressure disappearance, linkage rebulids the cooperation of lid, and promptly the U-shaped sheet metal is got back to substantially perpendicular to the position of the axis that covers and the inwall of relative container and kept outer leg wall securely.Compression piece cooperates until crimping tight seal power in clamping slot after getting back to crimping.The top that raises up allows by at first relative clamping slot reduction top and opened clamping slot before crimping slides through to start joint mechanism.In the process of folder upper top roof, can reduce by applied pressure, around lid, assist to operate up to palm to be easy to finish on the folder.

The crimping of container can form crooked crimping or the edge of rolling fully, and the perhaps crimping rolled of part or the edge of partly rolling are perhaps as bandy limit flange.Easy and the comfortable folding action of lid can realize that under any circumstance this just can obtain final anti-leak and stable lid and keep effect.The a plurality of bead designs of lid design fits.

Described be stamped in view of optimize and easy folding action and being designed, although under situation about being caught on, need force fit.Because its shape, described lid heart zone therein is harder relatively, just by extruding in the direction on folder and the guiding by guide hump with open clamping slot by the motion of the relative compression piece in top temporarily, crimping can be easily and is fully clipped in the clamping slot and closely cooperate and force fit with formation like this.

In order to realize this function, the basic plane of U-shaped sheet metal and being basically perpendicular to covers that axis extends and interior leg wall is basically parallel to that to cover axis be very important.Because these architectural features, when downward pressure is applied to when covering, the linkage effect of one fine is mainly due to the reason of machinery, the outer leg wall rigidity when the U-shaped sheet metal tilts of interior leg wall wall is bigger, and so then outer leg wall curves inwardly and opens clamping slot then from the inboard temporarily.

Before crimping begins the described compression piece of elastic deformation, when outside face is cooperated with wall of container slidably, be favourable.This effect that has is that clamping slot and compression piece almost are respectively put on the crimping on the position of ingenious centering, and crimping will overcome essentially identical resistance with by its whole circumferential lengths like this, and be easy to thus and clip in the clamping slot equably.

Roughly the same when the cone angle of outside face and wall of container, the internal diameter of the wall of container of the external diameter of outside face in the height and position of compression piece must at least roughly corresponding open area is felt relieved like this and is guided effect to begin before crimping arrives compression piece.When rolled edge connection in clamping slot, especially the softer material of container is will be in crimping and wall of container crooked, when covering when being caught on, can set up stronger just cooperation like this.In addition, because the result of the contact pressure between outside face and the wall of container, the outer leg wall of lid depression can curve inwardly a little.

The external diameter of the outside face in the clamping slot even can be bigger than the internal diameter of the wall of container in the open region, promptly inwall curves outwardly in the crimping.This measure guarantees in crimping enters whole moving process in the clamping slot by compression piece, and significant guiding and centering will take place.Diameter dimension is excessive to be approximately 3.5%, is favourable in the scope between about 1.5% and 5% promptly, and this depends on the size of container.

The centering and the guiding effect of extending significantly downwards intention that outside face surpasses the height and position of compression piece are important.Described lid can be by substantially only on applied pressure presss from both sides on the top.Outside face can have at least 2.5 times of height of clamping slot.3 times height is provided, perhaps or even the height of 4 times clamping slot also can be better.Must be noted that because the pressure between outside face and the wall of container also passes through bigger area of contact, extremely efficient sealing effect will be replenished the sealing effectiveness of crimping in clamping slot.

Bevel angle is between 6 degree are spent to 12, that is, whole cone angle is favourable between about 12 degree and 24 degree.Preferred angular range is between about 8 degree and 10 degree, promptly all between about 16 degree and 20 degree.

The local formed depression that dome top wall combines with outer top wall makes the folding action that is easy to lid become convenient and has increased the rigidity at top.In addition, described depression provides the visual cues that applies finger position and has been defined for from lid and piled up the comfortable bite that removes described lid.Undercut depression not only provides the hand folder, even the qualification lid piles up shoulder.Each lid can only be arranged on the shoulder of the depression on the next dome top wall of covering, and the Gai Buhui in piling up like this blocks.

In order to realize the strong force fit between crimping and the clamping slot, this is very important to sealing effectiveness, and the radial wall thickness of crimping must be greater than the radial of clamping slot.In case when crimping was arranged in clamping slot, the softer paper of container or the material of paper board material and crimping were crooked on the inboard and the outside respectively.With the zone of planar contact area extruding, that is, be not only the line contact, produced the sealing effectiveness of improvement.

The radial wall thickness of crimping must be greater than the 10%-20% of the average radial inner width of clamping slot, and preferably 15%.The result of this size is better sealing effectiveness, and lid is clipped to only needs suitable power simultaneously on the container.

For the maintenance effect that improves the crimping loam cake is also pushed described material gradually, the radial of clamping slot can reduce in the direction relative with direction on the folder; Favourable situation is the cone angle with wall of container.Like this, clamping slot is inserted into effect with generation and finally is set in place up to crimping.

In order to improve the maintenance effect of folder loam cake, at least one belt-like zone with friction coefficient of increase should be arranged on the inwall of the outside face of outer leg wall and/or container.This may cause covering and the cover gab zone of container and rigidity between the frictional engagement of increase.

Other important aspect of the present invention is that compression piece can be made of the darker and more shallow continuously depression that forms from the outside.Preferably, the dark more week that is recessed in makes progress longer than more shallow depression.This has made things convenient for folding action, but has caused stable and lasting maintenance effect, and hardening around the feasible lid.

A plurality of beverage identification projectioies that raise up in the dome top wall can be set up, to allow from the type of outside identification liquid for example laughable, strong suitable cola, orange juice etc.Described projection can be push-in buttons.

Further generally important aspect is formed in the penetration region in the dome top wall.This zone can have thinner than dome top wall at least wall thickness, and has the line of intersecting, and suction pipe can cosily intersecting rules inserts by tearing.The wall thickness that reduces allows suction pipe is more easily inserted.The wall thickness that reduces can produce by the material of partial compression lid.It is more useful to the harder relatively lid with wall thicker than traditional lid to have the zone that reduces wall thickness.But it is favourable to all such lids that thinner zone is provided, because this kind measure facilitates the introduction of suction pipe usually.

The penetration region that is used to facilitate the introduction of suction pipe is arranged on the bottom of depression, promptly is positioned at the center of dome top wall.Because make folding action become easily, the bottom wall thickness that is reduced has increased the rigidity at top.

Penetration region can curve inwardly to facilitate the introduction of suction pipe and the opposing resistance by the outside flexing of pressure of liquid.Bending also makes suction pipe be drawn out of afterwards and when fluid pressure acted on the tab that limits by open circuited line internally, open circuited line had the effect of auto-closing.The profile of the depression of corresponding two ellipses has increased the rigidity at top and provides attracting outward appearance to top design, and its main shaft is offset 90 degree each other.Line forms along the main shaft of two ellipses easily.The thin walled core that only has a bottom is enough, and is convenient so that suction pipe is introduced.

Other importance of the present invention is the easier folder loam cake that is used for conical double wall paper or cardboard containers.Double wall paper or cardboard containers have the open area traditionally, at this place's inner container wall outside elastic deformation and be connected with outer vessel walls on ladder.Crimping is formed on the upper end of inner container wall.The cone angle of the conical inboard wall of double-walled container is bigger under the upper open mouth region that broadens, and described upper open mouth region forms continuous bottom container wall by circumferential shoulder and has littler even be 0 cone angle than bottom container wall.Be placed on covering when crimping contacts with compression piece on the crimping and contact the open area inwall that broadens with guide cone by centering.In the process of the action on folder, described lid is felt relieved and is guided on crimping.Centering and guide hump inwardly spur owing to the distortion that is taken place between top that is depressed and clamping slot, so the easier compression piece that passes through of crimping.When folder is gone up, cover the leak-proof and rigidity that in the vessel port zone, provides higher.

Easily, the cone angle of outside face or centering and guide hump can be 0 or less than the angle value of the cone angle of container inner wall.Harder centering and guide hump force crimping to be in leakproof in clamping slot state are set, even can make the distortion of open area of double-walled container for strengthening container edge part hardening and leak free purpose.

In the case, centering and guide hump must be used for the inside step-portion of the outer leg wall of cooperate with the pressure fitted of wall of container and continuous downward by size.Inwardly step-portion should have the cone angle of the inner container wall cone angle that equals substantially under the upper step open area.Cooperation between step-portion and the container inner wall even the sealing effectiveness of reinforcement is provided in the depths of container.

The specific embodiment

The lid D that is used for cup-shaped receptacle C is from pulling out such as the elastoplast foil material and have a wall thickness 0.3-0.5mm (Fig. 1), and described cup-shaped receptacle C is made of paper or cardboard or plastic material.Described tea cup with a cover is used for clipping to the open area 9 of container C, the mode closure of described like this container C not have to leak, and covering D like this will can not break away from, even can not when entire container C overturning yet.Lid D (Fig. 1) is provided with on every side circumferentially continuous clamping slot 1, is positioned on the plane of described clamping slot 1 top 2 vaults on the inboard of clamping slot 1.Separate by circumferential basic evenly lid depression V from clamping slot 1 at top 2, and be provided with almost planar top roof 5 and several circumferential distribution depression 3.With respect to clamping slot 1, the outer leg wall 4 of lid depression V (Fig. 2) significantly extends beyond the plane of clamping slot 1 downwards.

Lid D (Fig. 2) is by only being applied to pressure on the open area 9 that clips to container C (Fig. 3) on the dome top wall 5 in the direction on folder.Dome top wall 5 is basically parallel to the plane of covering D and extends.Lid depression V has U-shaped cross-section and centers on top 2 with one heart.Lid depression V limits by outer leg wall 4, bottom U-shaped sheet metal 22 and interior leg wall 23, and described outer leg wall 4 is tapered downwards in this embodiment, and described interior leg wall 23 forms upwardly extending exterior top wall.Outer leg wall 4 has outside face 6, and described outside face 6 extends in the clamping slot 1.Outside face 6 is provided with cone angle/2, and these can corresponding basically bevel angle α/2 of the wall of container 7 of container C at least.

On the lower end of the wall of container 7 in Fig. 3 container bottom 8 is set, simultaneously the open area 9 of container limits by wall of container 7 with to outer lug crimping 10, is preferably limited by constituting so-called curved edge 11 by the cardboard of container C or paper material.Under the situation of plastic container, crimping 10 also can form by injection molded.Crimping can be the crimping partly rolled or to the rim lip of the container of outer lug conversely.

Fig. 4 has shown the lid D on the crimping 10, and described lid forms crooked edge 11.The compression piece 14 of lid D is arranged on the crimping 10.

Outer leg wall 4 is parallel to the plane of lid in the upper end by basic extension and by circumferential baffle plate 13 and continuously.Baffle plate 13 is basically parallel to the axis that covers D and down extends to compression piece 14.Described compression piece 14 can be from exterior groove shape depression and form interior circular top part 15.Described top 15 and compression piece 14 can week upwards continuously, perhaps be the outline independent local dent of (indicated by a dotted line) continuously roughly betwixt alternatively.Compression piece 14 is down continuous by the inclined wall outward 16 that limits folder ramp 17.From wall 16, other baffle plate 18 extends downwards, and in outward flange 19 terminations.The height of other baffle plate 18 can be shorter than what show.

10 the sweep from vertical container wall 7 to crimping the radial wall thickness Y of the crimping 10 measured of transition portion can be bigger than the radial Y1 of clamping slot 1.Radial wall thickness Y can surpass inner width Y1 10%-20%, preferably about 15%.In clamping slot 1, radial Y1 reduces gradually, preferably has cone angle/2 from compression piece 14 towards wall 12.

Length L between the inboard of clamping slot 1 qualification top 15 and wall 12.Outer leg wall 4 extends beyond the height and position L1 length of compression piece 14 downwards, and described length L 1 can equal height 2.5 times of L at least, and preferably 3 times, even 4 times of height L or bigger more preferably.

The inside diameter D 7 of the wall of container 7 on the height and position of compression piece 14 on the most of at least corresponding crimping 10 of the outer diameter D 1 of the outside face 6 of the outer leg wall 4 of (for example the top 15) is promptly from vertical container wall 7 to crimping on the transition portion of 10 outside sensing sweep.With wall 12 intersection points on outer leg wall 4 outside face 6 outer diameter D 2 in addition significantly than the preferably big 1.5%-5.0% of inside diameter D 7, preferably approximately be 3.5%.

When pressure R in Fig. 4 is applied on the top 2, outside face 6 is contacting container wall 7 before crimping 10 arrives compression pieces 14 or simultaneously slidably.Cover the depression V-arrangement and become centering and guide hump K, operate on the simple folder of described projection support and convenient cap D.Even be favourable when before crimping 10 arrives compression pieces 14, having set up moving contact.As lid D still down extruding, crimping 10 is with outside elastic deformation compression piece 14; In the process of this operation, on it moves to top 15 and before snapping in the clamping slot 1, crimping 10 is distortion (Fig. 5) a little also.The indication of shadow region shown in Fig. 5 is formed into and is extruded zone 20,21 in crimping 10 and the wall of container 7, with the effect of enhanced leaktightness, maintenance and hardening.Alternatively and this other places, outer leg wall 4 also can curve inwardly a little (dotted line with 21 ' is indicated).

Lid D among Fig. 6-10 has carried out revising design to compression piece 14 with different being of lid D among Fig. 1-5, and is the depression 24 in the dome top wall 5.Compression piece 14 (Fig. 7) forms by alternately continuous darker and more shallow depression 16a, 16b.Depression 16a, 16b form snake linear (snake lineshaped) inside top 15 '.Darker depression 16a can be longer than more shallow depression 16b in circumferential direction.In addition, Fig. 7 demonstration has shown shorter baffle plate 18 with dotted line 19 '.

In Fig. 6, depression 24 has dome top wall of being basically parallel to 5 and is arranged on the bottom top area 25 of the finite size under the dome top wall 5.The wall thickness x of lid D is constant substantially.Has only zone 25 by compression described material attenuation (thickness x1).The zone 25 be set at dome top wall 5 in the heart.In order to introduce suction pipe, zone 25 is formed with the opened line 26 of intersection.Easily, zone 25 can be towards the top 2 inside bend.

Depression 3 the transition portion from dome top wall 5 to interior leg wall 23 has increased the rigidity at top 2 and has allowed by finger tip clamp cover D, for example in order more easily to remove described lid D from lid piles up, and will cover D and be placed on the container C.Power R even can apply on the folder by the depression on the top 3.But, preferably, simple folder go up operation can by with palm by on smooth dome top wall 5, carrying out.

In Fig. 6, outer leg wall 4 can have a banded circumferential zones 30 at least, and the friction coefficient in the described zone increases the maintenance effect to realize strengthening when lid D is caught on.Zone 30 can be provided with highlyer than what show, perhaps can be narrower or wider.Respectively have the zone that increases friction coefficient and also can be arranged on each wall 7, perhaps on the zone 30 that covers, perhaps be arranged on zone 30 concerted actions of covering on the D.

Circumferentially design and the shape of continuous hinge structure M by top 2 and lid depression V is integrated into and covers on the D.Linkage can assist to press from both sides loam cake D, especially shown in Fig. 6-10.

The linkage M of lid D is made of top 2, interior leg wall 23, U-shaped sheet metal 22 and outer leg wall 4.Outer leg wall 4 in U-shaped sheet metal 22 and U-shaped sheet metal 22 define hinge 29 to the transition portion in the interior leg wall 23.The longitudinal axis that interior leg wall 23 is basically parallel to lid extends, simultaneously U-shaped sheet metal 22 be the plane and perpendicular to the lid axis.Must be noted that because the rigidity at top 2 and because the relation of the bigger diameter of the littler diameter of interior leg wall 23 and outer leg wall 4, outer leg wall will leg wall 23 easier bendings in internal ratio.This effect is used to open clamping slot 1 temporarily and realizes simple lid folding action.

In Fig. 8, lid D is placed on the crimping 10 of container C, and the whole circumferential extension of compression piece 14 will be felt relieved on crimping 10 like this.Outer leg wall 4 contacting container walls 7.Present folder is gone up power R and is applied to such as dome top wall 5, for example is by flat hand, reduces (Fig. 9) up to dome top wall 5.

In Fig. 9, antagonistic force R ' goes up power R with folder and acts on the contrary, because compression piece 14 is located on the crimping 10.Interior leg wall 23 passes through inner hinge 29 downward-sloping U-shaped sheet metals 22 at the transition portion from interior leg wall 23 to U-shaped sheet metal 22.Because the radial rigidity at top 2, the inclination of U-shaped sheet metal 22 has produced the power 28 that acts on the outer hinge 29.Power 20 discharges outer leg wall 4 from wall of container 7, like this in addition clamping slot 1 can on the inboard, open to a certain extent.Baffle plate 18 outwards moves on the direction of arrow 27 by antagonistic force R ', like this in addition clamping slot 1 can on the outside, open definitely temporarily.Under the effect of power R on the folder, because dome top wall 5 is lowered, also can be pressed into then on the wall 12, crimping 10 slides through compression piece 14 and clips to stably in the clamping slot 1 at last up to it.

In Figure 10, power R disappears on the folder.U-shaped sheet metal 22 is got back to by elasticity and is basically perpendicular to direction and the outer leg wall 4 of relative wall of container 7 extruding that covers axis.Baffle plate 8 also returns by elastic force.Clamping slot 1 keeps crimping 10 securely.Feel relieved protruding K and clamping slot 1 makes the opening portion hardening of container C significantly.

In Figure 11, depression 24 has the flower-shaped wall profile of pintongs, and promptly its profile can come flag sign, main shaft skew 90 degree of described ellipse by unidimensional ellipses such as two.Line 26 main shaft along two ellipses in zone 25 extends.Figure 12 has shown wall thickness x in the zone 25 and difference between the wall thickness X1 with magnification ratio.Zone 25 can be to curve inwardly, and as shown in the figure, perhaps can be parallel to dome top wall 5.The wall thickness x1 that is reduced is N/Rs to whole regional 25.When making when cover D by only providing the thin-walled core just enough to regional 25 such as compression material.

The radial width of the annular U-shaped sheet metal 22 among Fig. 6-10 can reach the about 10% of the external diameter that covers D, and the diameter of dome top wall 5 can reach about 60% of the external diameter that covers D simultaneously.

The embodiment of lid D among Figure 13,14 is similar to the embodiment among Fig. 6-12, but the beverage that is provided with regular distribution extraly in dome top wall 5 is distinguished protruding 5a.For example, have four oval beverage to discern protruding 5a, each has mark and/or can press the button at its top.This is the standard set-up of many lids on the market.Projection 5a is with the very little radial distance setting in the outside of leaving dome top wall 5 and also leave the very little radial distance setting of central concave 24.In addition, depression 3 is shaped on undercutting, and they pile up when removing by the easier clamping of finger tip (as shown in Figure 15) from several lids at lid D like this.Each caves in and 3 can limit side direction shoulder 3a, and described side direction shoulder 3a can be used for the drg that piles up as shown in figure 15, and shoulder 3a is arranged on the dome top wall 5 of the next one lid D that piles up like this.Shoulder 3a prevents that advantageously the lid that piles up from getting jammed within each other because covering of piling up shoulder 3a be arranged on the dome top wall 5 and outside the leg wall place of contacting with each other contact with each other.This feature causes orderly and fine and close piling up, and from described piling up, each covers D and can cosily remove.In an illustrated embodiment, be provided with eight depressions 3.

The lid D of Figure 13-15 also has centering and guide hump K (guide cone) and the linkage M that is used to make things convenient for folding action.

Figure 16 and 17 has shown the simple folder loam cake D that is used for double-walled container CD.Double-walled container CD has inwall 7 and outer wall 7c, has a. g. therebetween so that thermal insulation effect to be provided.Crimping 10 is formed on the upper end of inwall 7.Double-walled container CD at first forms cone angle/2 of arriving crimping 10 continuously.In the process that forms, the top of inwall 7 outwards broadens, and produces cone angle like this '/2 less than cone angle/2 or even be almost 0 open area 9a, form shoulder 7b like this.Double-walled container CD has centering and the guide hump K that has illustrated with lid D.In the case, protruding K is formed, like this outside face 6 or cylindrical (as shown in the figure) or have 0 degree (cylindrical) or to the value of cone angle ' but/2 similar '/2 less than cone angle between small-angle β/2.Outside face 6 or outer leg wall 4 are continuous by inside stepped wall portion 4b, and shoulder 4 is formed like this.The outer surface part 6a of the 4b of wall portion tilts with cone angle/2.The bottom of centering and guide hump K forms by U-shaped sheet metal 22, and described U-shaped sheet metal 22 is basically perpendicular to central lid axis and extends.The diameter D7 of open area 9a in the zone of the basic corresponding crimping 10 of diameter D1 of outside face 6.In the 9a of open area, the exterior section of the interior section of inner container wall 7a and outer leg wall 4 and the 4b of wall portion are instructed to distortion or press from both sides double-walled container CD fully and enter compacting pressure and contact when covering D.

In Figure 16, lid D feels relieved on double-walled container CD, like this crimping 10 from the bottom close compression piece 14.Then, outside face 6 has contacted inwall container 7a with on folder upward pressure R is applied to such as dome top wall 5 when (not showing) in Figure 16 in the 9a of open area, suitably feels relieved and guides described lid D.

Promote compression piece 14 through on the crimping 10 at the folder upward pressure, outside face 6 is used for pilot cap D.Downward-sloping when U-shaped sheet metal 22, what as above illustrated is such, and outer leg wall 4 moves inward a little, and compression piece 14 is outwardly-bent simultaneously.This has made things convenient for compression piece 14 to be easy to slip on crimping 10 until arriving position shown in Figure 17.Crimping 10 is from the outside and inboard clamping then.Contact wall portion (20 and 20 ') can be extruded.Shoulder 4a or be arranged on the shoulder 7b perhaps is closed into shoulder 7b at least.Specific contact pressure is realization in zone 20 ', causes except by between clamping slot 1 and the crimping 10 and the extra sealing effectiveness outside the sealing effectiveness that cooperation realized between leg wall 4 and the 7a of inner reservoir wall portion.In Figure 17, the rigid dome structure of lid D even can force between the 7a of inner reservoir wall portion and the outer leg wall 4 and become parallel relation, thereby higher confining force of generation and good effect and the remarkable hardening of opening portion of closed container CD.

In addition, the cooperation between shoulder 4a, the 7a can produce folder and go up the restriction brake component, prevents that rolled edge deformity is too many.Adjacent shoulder 4a, 7b even can in the prestrain closure condition, keep crimping 10 and clamping slot 1, and it is characterized in that having higher anti-leak and to the higher confining force of lid D.

Figure 18 is the section drawing of the folder loam cake D on the one-wall vessel C.Similar to Fig. 5.Crimping 10 is fully inwardly to curl.The clamping slot 1 of lid D is a circular cross section.The shade hatching represents than strong contact, for example even the zone of the surface portion that is extruded a little.Clamping slot 1 and crimping 10 the girth of crimping 10 greater than 180 degree on closed contact.Outer leg wall 4 makes the remarkable hardening in upper shed zone and does not have radial deformation.
