The invention relates to a closure for bottles, cans, in particular containing medicaments etc. with the counting or display device actuated by the opening and closing movements.

Containers with lids have already been used for the packaging of medicines, which containers divided into individual compartments, each containing a specific number of tablets for each intake are. With the help of a marking on the lid and container edge it can be determined when z. B. the next dose is required. These pill dispensers have the major disadvantage that Variations in the dose to be taken are only possible if the intake times are not displayed as more or fewer tablets than are available in a compartment may be administered have to.

These disadvantages can e.g. B. made using the display closure according to the invention Containers to be overcome, since the one-time opening the container to be removed The number of tablets can be any and is only determined by the therapeutic requirements.

Furthermore, the closure according to the invention can also be used in connection with containers containing powders or liquids and indicating when to return to the container to be opened or how often it has already been opened.

Such a new closure for bottles, cans, etc. with the opening and closing movement actuated counting or display device is by a rotatably mounted on a lower part of the closure body marked with a display or counting disc arranged between the lower part and the closure body. The closure body has a display opening, and there is a nose on the lower part, on the closure body elevations and on the indicator disc approaches for adjusting the disc by the relative movement between the closure body and the lower part during an opening and Closing movement provided.

The elevations and essentially all of the approaches preferably provide ratchet notches or -latch, and the nose and a shoulder are designed as ratchet latches.

Furthermore, the closure body can have a groove in its edge in which the flange of the lower part slides.

The in F i g. Display closure 10 according to the invention shown in FIGS. 1 to 8 includes a lower part 12 designed as a container, a cover or closure body 14 and a display or counting disk 16. The container 12 has an open head end 18 which is surrounded by the upper edge 20 . In the cylindrical

809 598/16

Wall 24 of the container 12 is provided with a rectangular opening 22 reaching up to the upper edge 20. On the outside essentially enclose a narrow flange 26 and one aligned with it Stool 27, the wall 24. The upper edge 20 has a nose 28 with an inclined surface 29, so that the Nose - as explained below - serves as a latch. This nose 28 is immediately adjacent to the Breakthrough 22 on.

The closure 10 counter used with the closure 10 for displaying successive bodies 14 has a flat upper part 30 with a cylindrical edge 32 hanging downward dividing the relative movement between the cover 14. The edge 32 and the counting disk 16 can be viewed
lies close to the wall 24 and has an opening. In the closed position of the cover 14, the lies

36. The edge 32 is on the inside with a groove projection 38 on an edge 64 of the opening 22. 34 with a closed end 35 at the opening 15 is used to open the lid 14 with respect to the 36 provided. The groove 34 is rotated with the flange 26 in the container 12, so that the

wisely provided with characters 60, which denote the different days of the week. The nose 28, the bumps 44 and the lugs 56 and 58 cooperate in this closure 10 to the counting disc 16 to rotate so that the successive characters 60 when using the shutter 10 through the window-like opening 40 become visible. The characters 60 and the window-like opening 40 can thus as a cooperating display means of a

Engagement, thereby preventing the lid 14 from being moved away from the container 12. The opening 36 operates with the aperture 22 during use of the closure 10 - as explained below - together.

«When the lid 14 is mounted on the container 12, there is a small, provided inside on the edge 12, to the opening 36 adjoining projection 38 in the opening 22. In this way, when turning of the lid 14 with respect to the container 12 prevents the opening 36 from the opening 22 is located away. In the upper part 30 of the cover 14 there is a small window-like opening 40 intended. The upper part 30 also includes in the middle one arranged centrally with respect to the edge 32 cylindrical extension 42 a.

In the cover 14, several ratchet-like elevations are still on the upper part 30 adjacent to the edge 32 44 provided. These elevations are directly opposite the upper edge 20 when the cover 14 is placed on the container. All elevations 44 are shaped identically and at equal intervals arranged from each other. Each of the elevations 44 has an inclined surface 46 and perpendicular to the upper part 30 an end face 48.

The counting disk 16 has a hole 50 surrounded by a spacer flange 52 in the middle. The hole 50 is designed so that the counting disk 16 is rotatably mounted on the extension 42 by sliding it on can be. In this position, the flange 52 rests on the upper part 30 and holds the main part of the counting disk 16 at a relatively short distance from this upper part 30. If necessary, can a small retaining flange 54 at the outer end of the attachment 42 are arranged to prevent the counting disk 16 from sliding off this approach.

The counting disk 16 preferably includes a projection 56 attached to its periphery so that it is opposite the elevations 44 and touches them. If desired, several approaches 56 be provided; however, this is usually not required. The counting disk 16 also has nor the same number of other approaches 58, such as elevations 44 on the upper part 30 are present. the Lugs 56 and 58 are shaped in the same way as the elevations 44; they therefore also have inclined surfaces and vertical end faces. However, these approaches 56 and 58 are designed so that they only in a direction of rotation about the axis of the edge 32 can be detected by the elevations 44.

If seven elevations 44 are used on the closure 10, the counting disk 16 is vorzugrung with the projection 56 located elevation 44 the rotational movement of the lid 14 on the counting disk 16 to rotate them simultaneously. During this rotation of the disc 16, the lugs 58 move with respect to the nose 28, whereby a new lug 58 comes into engagement with the nose 28. Such a rotation of the cover 14 with respect to the container 12 is limited by the projection 38 which strikes an edge 66 of the opening 22 opposite the edge 64. When the projection 38 rests on the edge 66 in the open position, the opening 22 is aligned with the opening 36, and any contents can be removed from the container 12.

To close the closure 10, the cover 14 is rotated in the opposite direction. Included the rotation of the counting disk 16 is prevented by the contact of the nose 28 on the adjacent shoulder 58. In this way, the counting disk 16 is not moved during the closing process the cover 14 rotates in relation to this disk, whereby the window-like opening 40 over an earlier hidden character 60 is moved. The rotation during the closing process is caused by the impact of the projection 38 is limited to the edge 64 of the opening 22.

With the stool 27, the lid 14 is closed Position held by the stool rubbing the locked end 35 that is between the stool 27 and one end of the flange 26 fits. The closed end 35 must therefore be opened and closing the lid 14 can always be moved over the stool 27.

The nose 28, the bumps 44 and the lugs 56 and 58 act to change the position the counting disk 16 to bring about the cover 14 as soon as the shutter is opened or closed will. In this case, the elevations 44 and the projection 56 serve to hold the cover 14 and the counting disk 16 rotate together in one direction, while the nose 28 and the lugs 58 the rotation of the Allow counting disc 16 with respect to container 12 in the opposite direction, but the rotation prevent opposite to this direction. The nose 28 and the lug 56 in the closure 10 thus act as pawls cooperating with the corresponding elevations 44 or projections 58, while the bumps 44 and lugs 58 are ratchets.

This effect achieved in the closure 10 by ratcheting and latching depends on the relative flexibility of the counting disk 16 with the approaches 56 and 58. The function of the

The necessary flexibility can be achieved by manufacturing the counting disk 16 from essentially any suitable material, for example from flexible sheet metal or the like. Preferably, however, this disk 16 is made of a somewhat elastic plastic, such as polystyrene, linear polyethylene or the like. The counting disk 16 can be conveniently snapped into the correct position if the cover 14 is made of a similar material. Furthermore, in this case the lid 14 can easily be snapped onto the container 12 in the correct position. The container 12 is preferably made of clear material so that its contents can be checked.

If in a closure 10 the characters 60 correspond to the seven days of the week, the opening 36 must be dimensioned such that it extends over a seventh of the circumference of the edge 32. The opening 22 must extend over the same distance plus an amount corresponding to the dimensions of the projection 38. If the closure 10 is formed so that the characters 60 correspond to any evenly numbered sequence, the widths of the aperture 22 and the opening 36 are dimensioned as indicated, the width of the opening 36 being equal to the circumferential portion of the edge corresponding to the number of characters 60 32 is. In any case, the number of elevations 44 and projections 58 must correspond to the number of such characters 60.

In Fig. 9 and 10, a modified closure 70 according to the invention is shown which essentially corresponds to the closure 10 described. To simplify the explanation, here are those Parts of the closure 70, which with the corresponding parts of the closure 10 completely or in the are essentially identical, not described separately; they are according to the embodiment 1 to 8 denoted by the same reference numerals provided with dashes.

In the case of the closure 70, the extension 42 is replaced by a circular opening 72 which has a constriction 74 in the center. In this closure 70, instead of the hole 50, a projection 78 is provided on the counting disk 16 ' which fits into the opening 72 in such a way that the counting disk 16' is held rotatably with respect to the cover 14 '. This extension 78 preferably carries a pointer 80 which can point to any of the characters 82 corresponding to the characters 60. These characters 82 are attached to the upper part 30 'of the cover 14'.
