Definitions

• Container for storing tablets
• the present invention relates to a container for storing pills, of the type described in the preamble to claim 1.
• Such containers are well known and have long been used for storing pills or tablets , particularly pills for medicinal purposes.
• persons who regularly take medicine have reduced mobility, particularly fine motor function, as a result of illness or old age, and it is therefore desirable to be able to open or close such containers without unnecessarily complicated rotary manipulation.
• the wrap of the screw-threads on the lid and the container part should therefore be as short as possible.
• This sealing function is achieved mainly by the threads cooperating with each other and in order to achieve satisfactory sealing it is therefore important for the wrap of the threads to be as large as possible, a wrap of several revolutions often being required. This requirement is in opposition to the need mentioned in the introduction, of being able to open the container with as little angle of rotation as possible.
• Conventional closures have either involved a compromise between these two demands or have been aimed at satisfying only one of them and disregarding the other.
• the purpose of the present invention is to endeavour to solve this problem and provide a container which is both easy to open and also satisfies the demand for good sealing.
• the main sealing function being located at the outer edge of the container part in cooperation with surfaces on the bottom of the lid, the contact between them being along three circular sealing lines, a perfectly satisfactory sealing function is achieved without the sealing effect from the threads engaging in each other having to be considered. Since the sealing aspect for the threads in a container according to the invention can be entirely neglected, these can be given minimum length corresponding to that necessary to properly ensure that the lid remains on the container part and is not accidentally screwed off. It has thus been possible to make these with an extension of approximately 270° or even less.
• the bottom of the lid is provided with a circular groove to receive the container part, the sealing lines being situated close to the groove. It is advantageous to make one of the side walls of the plate cylindrical and the other conical and to provide a ridge at the bottom of the groove. Efficient sealing lines are thus achieved in a simple manner.
• the container is provided with a plurality of threads, preferably three on each part, which further simplifies manipulation, particularly when screwing on the lid.
• the invention is particularly intended for use with containers manufactured out of plastic. This further increases the sealing function since, due to the relatively great deformability of the material, the sealing lines will be somewhat extended in transverse direction and in practice form ribbon-shaped sealing surfaces.
• the invention is extremely suitable for use with lids of security type where an axial force pressing the lid against the container part is required to enable the lid to be screwed off.
• the lid is provided with a lightly applied strip or collar providing an indication as to whether the container has been opened or not.
• Figure 1 shows a longitudinal section through the container part of a container according to the invention
• Figure 2 is a view of the container part in Figure 1, seen from above,
• Figure 3 shows a partial longitudinal section through the lid of a container according to the invention in a first position
• Figure 4 shows a corresponding section through the lid in Figure 3 in a second position
• FIG. 5 shows an alternative embodiment of the lid in a section equivalent to that shown in Figure 3,
• Figure 6 is a view of the lid in Figure 6 seen from above,
• Figure 7 is an enlarged partial section of Figure 3.
• the container part 1 in Figure 1 is a jar for pills and is manufactured from HD polythene. It has an upper cylindrical portion provided with three threads 3, 4, 5, each with an angle of wrap of 270° and a pitch of approximately 1:10. In the embodiment shown the lower part of the container in which the pills are stored is also cylindrical but could have any shape. Between the cylindrical portion 2 provided with threads 3, 4, 5, and the lower part of the container 1 is a cylindrical neck portion 6, provided with four bosses 7. These can be seen most clearly in Figure 2 and their function will be described later on.
• Figure 3 shows the lid 8, 9 of the container part 1 shown in Figures 1 and 2.
• the lid consists of an inner part 8 and an outer part 9 and is made of polypropylene.
• the inner part 8 is provided with three threads 10, 11, 12 on its cylindrical part, each having an angle of wrap and pitch corresponding to the threads on the container part 1 so that they can be screwed into each other.
• the lid is of security type, constructed so that the lid parts 8, 9 must be pressed together axially for the inner part 8 to accompany the outer part 9 when this is turned in opening direction.
• Figure 3 shows the lid in this compressed position.
• the side of the inner part 8 facing the container part is provided with a strip or collar 15 secured with the aid of a number of tongues 17. These tongues are thin and can be broken with relatively little force.
• Four bosses 16 are arranged on the inner side of the collar. When the lid 8, 9 is screwed onto the container part 1 the collar 15 is located around the neck portion 6 of the container part 1. The bosses on the collar 15 and the bosses 7 on the neck portion of the container 1 are arranged to hook into each other when the lid is turned in opening direction.
• the tongues are torn off so that the collar 15 is separated from the inner part 8 of the lid and assumes a position resting around the neck portion 6 of the container part.
• This tearing of the collar 15 from the inner part 8 of the lid occurs the first time the lid 8, 9 is removed from the container part 1.
• the fact that it is separated from the lid thus serves the function of indicating that the container has been opened.
• the cylindrical outer surface of the outer part 9 is shaped with peaks 18 and valleys 19 in a wave pattern in peripheral direction in order to facilitate turning.
• the outer part 9 of the lid is provided on its upper side with gripping means 20 which for some people offers an alternative that facilitates mrning.
• the gripping means 20 is in the form of a ring standing up from the lid and having diametrically opposed slits 21.
• the lid can be opened with the aid of these by pressing the container against the edge of a slab-shaped object, e.g. the edge of a table. With the edge of the table engaged in the slits 21, the container is easily opened by turning the container part 1 while the lid is prevented from turning by the edge of the table.
• the inner part 8 of the lid is provided at the bottom with an annular holder in which a container 22 with desiccant material 23 can be applied.
• the inner part 8 of the lid is also provided with an annular flange 25 and an annular groove 26.
• the lid 8, 9 is screwed onto the container part 1, the outer edge 27 of the cylindrical portion 2 of the container part extends into the annular groove 26 and seals against the adjacent surfaces thereof.
• Figure 7 which is an enlargement of a section through the portion around the flange 25 and groove 26, shows how the outer edge 27 of the container part cooperates sealingly with the inner lid 8.
• the annular groove 26 is limited in radial direction on its inner side by the outer cylindrical surface of the flange 25 and on its outer side by a conical surface 29, half the top angle of which is approximately 25°.
• the bottom 30 of the groove is substantially flat and is provided substantially centrally with an annular ridge 31 having triangular cross section.
• the depth of the groove is approximately 5 mm and its breadth is approximately the same.
• the ridge has a height of approximately 0.3 mm and a top angle of approximately 60°.
• the figure also shows a fourth sealing line D between the conical surface 29 and the corner of a section of the cylindrical portion 2 having slightly larger diameter than at its outer edge. Sealing along this line D is less efficient, however, and is deemed passive since the true contact force in axial direction occurs along the lines A and B, this force preventing further penetration of the cylindrical portion 2 into the groove 26. Any contact occurring along the line D must therefore be rather light.
