Description

Tablet storage case

Technical field

The present invention relates to a housing for storing tablets, in particular tablets for medical purposes.

BACKGROUND OF THE INVENTION

Such capsules and reservoirs are well known and have long been used for storing pills or tablets, especially pills for medical purposes. In many cases, persons who regularly take a drug have reduced mobility, especially a fine motor function, as a result of illness or old age and are therefore desirable to be able to open or close such capsules without unnecessarily complicated rotational manipulations. Thus, the circumference of the screw threads on the lid and the cartridge portion must be as short as possible. At the same time, it is important that the cap sufficiently seal the housing to protect its contents (63). This sealing function is achieved in particular by co-operating threads, and in order to achieve a satisfactory seal, it is important that the circumference (sheath) of the threads is water.

the largest, often requiring a sheath of several revolutions. This requirement contradicts it to the need stated in the introduction that the housing is to be able to open with as little rotation angle as possible. Conventional closures either contain a compromise between the two requirements or are aimed at satisfying only one of them and ignore the other.

SUMMARY OF THE INVENTION

The purpose of the present invention is to solve this problem and to provide a cartridge housing for storing tablets which can both be easily opened and satisfy the requirement of good sealing.

dV t7

A container for storing pills or tablets (with a cartridge portion) with an opening and a lid for closing the opening, the opening being surrounded by a cylindrical portion of the cartridge

In part, the cylindrical portion is provided externally with at least one screw thread and the cap has a second cylindrical portion which is internally provided with at least one thread configured to interact with the thread on the cylindrical portion of the cartridge portion for screwing and unscrewing the cap from the cartridge portion. an inner bottom with a circular groove into which the outer portion of the cylindrical portion of the cartridge portion is axially inserted while fully screwing on the lid to achieve sealing contact therewith along at least three lines of circular-shaped gaskets which is defined by a bottom, one conical side wall and one cylindrical side wall, the bottom being provided with a comb-like projection. An effective sealing is thus achieved in a simple manner.

of

In a preferred embodiment, the ridge has a triangular cross-section with a free apex pointing from the bottom to the container part.

In a further preferred embodiment, the seal line housing has a position such that the first seal line runs along the conical side wall, the second seal line runs along a portion of the ridge (facing the container portion 11), and a third line seal. runs along a cylindrical wall (28).

Thanks to the main sealing function, which is located on the outer edge of the cartridge part in cooperation with the surfaces at the bottom of the lid and the contact between them along the three circular lines of the seal, a perfectly satisfactory sealing function is achieved without considering the sealing effect of the interlocking threads. each other. Since the sealing aspect for the threads in the sleeve of the present invention can be completely neglected, the threads may have a minimum length corresponding to the length necessary to adequately ensure that the lid does not remain on the cartridge portion and cannot accidentally be unscrewed. As a result, it is possible to produce them with a helix angle of approximately 270 ° or less. Thus, in a preferred embodiment, the sleeve has a helix angle of 270 ° ± 30 °, preferably 270 °.

According to a further preferred embodiment, the sleeve has a cylindrical portion of the cartridge portion and a cylindrical portion of the lid each provided with at least two turns, in a particularly preferred embodiment the number of turns on each cylindrical portion of both the cartridge portion and the lid is three.

The advantage of this embodiment is simplification of handling especially when screwing on the lid.

The invention is particularly intended for use with housings made of plastics. This further increases the sealing function since, due to the relatively high deformability of the material, the sealing members will be somewhat elongated (stretched) in the transverse direction and thus practically form the sealing surfaces in a ribbon shape. Thus, in a preferred embodiment of the housing, the material of the container part is and / or the lid is plastic.

According to yet another preferred embodiment, the housing has a lid on the outer surface of its cylindrical portion provided with elongate protrusions and depressions.

The invention is particularly suitable for use in security caps where an axial force is required to push the cap against the cartridge portion to allow the cap to be unscrewed. According to such a preferred embodiment, the housing has a lid that includes an outer portion and an inner portion, the lid threads being disposed on the interior of the cylindrical portion of the inner portion, the two lid portions being coupled to each other to rotate in the opening direction of the inner portion only parts.

The housing may advantageously have a ring at the end of the lid facing the container part, which is detachably connected to the lid, the detachable connection being adapted for easy separation. This provides the user with information whether the cartridge has been opened or not.

According to a further preferred embodiment, the sleeve may have protrusions on the outside of the container part, while the ring is internally provided with further protrusions arranged to engage the protrusions on the outside of the container part, the engagement of the cooperating projections defining the relative rotation angle between the ring and the container part. ).

DETAILED DESCRIPTION OF THE INVENTION

The tablet housing has a reservoir portion 1 in Fig. 1 as a talc container which is made of high density polytene. This container part 1 has an upper cylindrical part 2 provided with three threads 3, 4, 5, each having a helix angle of 270 ° and a pitch of approximately 1:10. In the present embodiment, the lower part of the cartridge part 1 of the housing in which the tablets are stored is also cylindrical, but could have any shape. Between the cylindrical part 2 provided with the threads 3, 4, 5 and the lower part of the cartridge part 1 (/ the sleeve is a cylindrical neck part 6 which is sealing and provided with four projections 7 which can be made. .....

like risers. These protrusions 7 can be seen mostly clearly in FIG. 2 and their function will be described later.

Giant. 3 shows the lid 40 of the cartridge part 1 of the housing shown in FIGS. 1 and 2. The lid 40 consists of an inner part 8 and an outer part 9 and is made of polypropylene. The inner part 8 of the lid 40 is provided with three threads 10, 11, 12 on its cylindrical part, each having a helix angle and a pitch corresponding to the threads 3, 4, 5 on the cartridge part 1 so that they can be screwed into each other. The lid 40 is of a safety type and is designed such that its portions 8, 9 have to be compressed axially together so that the inner portion 8 accompanies the outer portion 9 when it is opened in the direction of opening of the housing. Giant. 3 shows the cap 40 in this compressed position. If the portions 40 of the cap 8.9 are not compressed, they assume the position shown in FIG. 4 with respect to each other. In this position, the outer portion 9 causes only rotation of the inner portion 8 in the housing closing direction, while the outer portion 9 will rotate freely around the inner portion 8. if rotated in the opening direction. The link members 13 and 14 on these two portions only allow rotation, from which they will open when the portion 40 / lid 40 is depressed.

·) -I

The side of the inner part 8 facing the cartridge part 1 is provided with a strip or ring 15 secured by a row of pens Γ7. These tongues are thin and can be broken by a relatively small force. On the inner side of the ring 15 are provided four protrusions 16. When the lid 40 is screwed onto the cartridge part 1, the ring 15 is disposed on the cartridge part around the tapered, and the ring 15 and the projections 7 on the tapered part of the cartridge 1 are arranged were hooked into each other if they did

the ring 15 is held by the cooperating protrusions 7 and 16, peeling off perayse so that the ring 15 is separated from the inner part 8 of the caps to assume a position resting around the tapered part of the cartridge part.

When the cap is removed from the cartridge portion L The fact that the ring 15 is detached from the cap 40 functions as a function indicating that the cap 40 has been opened.

As can be seen in Figures 4 and 5, the cylindrical outer surface of the outer portion 9 is wave-shaped with peaks 18 and seats 19 in the circumferential direction to facilitate rotation.

In the embodiment of FIGS. 6 and 7, the outer portion 9 of the lid 40 is provided with clamping means 20 on its top side of the gear, which, for some, provide an alternative to facilitating rotation.

The clamping device 20 is in the form of a circle standing out of the lid 40 and having a completely opposite plate-like object, e.g. against the edge of the table. When the edge of the table is inserted into the slots 21, the housing is easily opened by rotating the cartridge part 1, while this edge of the table prevents rotation of the lid 40.

As can be seen in FIG. 3, the inner part 8 of the lid 40 is provided with an annular holder at the bottom,

It is also provided with an annular flange 25 and an annular groove 26. When the lid / outer edge 27 of the cylindrical portion 2 of the cartridge portion 1 is screwed onto the cartridge portion 1, it extends into the annular groove 26 and from there sealing against adjacent surfaces.

Figure 7, which is an enlarged cross-sectional view of the portion around the flange 25 and groove 26, shows how the outer edge 27 of the cartridge portion 18 cooperates in sealing with the inner portion 8 of the lid.

The annular groove 26 is limited in the radial direction on its inner side outer.

the cylindrical surface of the flange 25 and on its outer side the tapered piston is!

·) -Ί

The -6Diao g ”half apex angle is approximately 25 °. The bottom 30 of the groove 26 is substantially flat and is provided with a substantially centrally annular ridge projection 31 having a triangular cross section. The groove depth / e is approximately 5 mm and its width is approximately the same. The ring is about 0.3 mm high and the apex angle is about 60 °.

When the cap 40 is fully screwed onto the cylindrical portion 2 of the cartridge portion 1, the active seal runs along the three active lines A, B, C of the seal running annularly between the inner portion 8 of the cap 7 and the outer edge 74 of the cylindrical portion. The groove 26 is dimensioned so that the contact extends substantially simultaneously along lines A and B of the seal. The contact force at the seal line A provides an effective seal against the corresponding corner of the edge 27, which is thus slightly deformed. Due to the conical shape, the contact force on line A of the seal acquires a radial component that pushes the outer end of the annular portion 2 inwardly adjacent to the inner surface 128 of the flange 25 so that an effective sealing member with a corresponding contact force is formed in the line region. C seal. The flat surface of the edge 27 will be pressed against said ridge projection 31Hehc / the tip will be slightly deformed, and an effective seal is also achieved in the region of the seal line B.

Thanks to these three lines A, B, C of the gasket, where the respective contact runs under pressure along all three, an efficient gasket is obtained which eliminates the need for the screw threads to have any sealing function. The figure also shows the fourth seal line D between the conical surface 29 and the corner of a portion of the cylindrical portion 2 having a slightly smaller diameter than its outer edge. Seal along this line

However, D is less effective and appears passive, since the actual contact force in the axial direction acts along lines A and B of the seal, preventing this further penetration of the cylindrical portion 2 into the groove 26. Any contact running along line D of the seal must therefore be light enough .

The embodiments described above ₍ are intended only to illustrate the nature of the invention and are not to be construed as limiting in any way. The invention may be modified in various ways and is limited only by the object or purpose defined in the main claim. it is not limited to use with a safety type lid, but can also be used on simple screw-on lids.
