Abstract
The invention relates to a capsule housing various types of substances and/or preparations which are to be swallowed. The capsule (1) is constituted by a container part (3), receiving the substance in question, and an upper part or lid (2). The upper closure part (2) consists of an inverted hat formation (4) the cylinder portion (7) of which can sealingly cooperate with and be inserted through the orifice (8) of the container part. A sufficiently wide slot (9) is arranged between the internal envelope surface (11) of the container part (3) and the external envelope surface (10) of the cylinder portion (7) to permit that, upon insertion of the cylinder portion (7) into the container part (3), air or any other undesired substance present in the container part will be expelled by pressure.
Description
Capsule
The present invention concerns a capsule adapted to house different types of compounds and/or substances which are to be swallowed. The .capsule is constituted by a container part housing, the compound and/or substance in question and by an upper part closing the container part .
The different types of capsules today on the market consist of two cylinder-shaped halves which are of approximately the same size and which, when joined telescopically, define a closed space for the drug or preparation to be swallowed by a person. Typically the capsules are manufactured in gelatine which melts when in contact with a liquid. It has turned out to be difficult to evacuate the oxygen or air remaining in the capsules after conclusion of the filling and closing steps, especially in connection with certain drugs and/or preparations such as different kinds of natural medicaments or any type of substance in integral, pulver or liquid form. This is a great problem since the remaining air reduces the activity endurance of the substance in the capsule.
The object of the present invention is to provide a new type of capsule within the category above mentioned at which this problem has been eliminated. The features characterizing the invention are set out in the claims enclosed.
Thanks to the structural character of a capsule designed according to the invention all surplus air is evacuated upon closure of the capsule because the lid closing the container part has been designed in a special way, so that the substance inside the capsule will occupy all of the interior volume of the capsule. Also, the conspicuous appearance of the capsule gives the consumer an optimal quality guarantee by informing him about the fact that no oxidazation has taken place since all oxygen has been evacuated.
Embodiments of the invention are described below by way of examples and with reference to the drawings.
Fig. 1 is a cross-sectional view of a prior art capsule not yet filled - but, upon completed filling of the lower container part and mounting of the lid part will contain a relatively large amount of air, Fig. 2 shows a first embodiments of the invention illustrating a capsule which is in its filled condition and from which all air has been evacuated in connection with the closing operation, Fig. 3 is a lateral view of a lid which has been used in the
Fig. 2 embodiment, Fig. 4 is a lateral view showing the container part of the capsule when in unfilled condition, Fig. 5 shows a lid or closure component, respectively, acording to the second embodiment comprising an extended, outer, bent flange, and Fig. 6 shows the capsule in fig. 5 as seen before the mounting of the closure component .
As appears from Fig. 1, it does show a capsule today available on the market and belonging to the category to which also the present invention relates. However, in order to make it possible upon filling of such a capsule completely to evacuate all remaining air or any other fluid and to end up with a capsule which is completely filled with the desired substance only, the lid closing the container part of the capsule has been designed according to the teaching of the present invention.
In the embodiment shown in Figs. 2-4 the lid, or the upper part 2 sealing off the container part 3 of the capsule 1, is constituted by an inverted hat formation 4 having a bottom 5, which in the example shown is flat, a cavity 6, and a cylinder portion 7 defining the cavity 6. Naturally, bottom 5 may alternatively have other configurations, such as having a convexe
surface facing the filling inside the container, or any other suitable shape adapted to the filling substance at issue. The cylinder portion 7 does sealingly cooperate with and can be inserted through the orifice 8 of the container part 3. A slot 9 is defined beetween the external envelope surface 10 of the cylinder portion 7 and the internal envelope surface 11 of the container part 3 in suxh a way that, when the lid 2 is mounted, air present in the capsule is expelled, in certain cases together with a small amount of the content of the capsule. But the amount of filling substan ce supplied is adapted to its compressibility so that over-filling is avoided. The upper portion of the container part 3 may be conical for the purpose of facilitating the mounting of lid 2.
As appears from the drawings and, more specifically, from Figs.2- 4 the lid 2 may be provided with a circumferentially extending groove 12 which cooperates with an inwardly projecting bulge 13 in order to keep the lid 2 scured to the container part 3.
In the embodiment shown in Figs. 5 and 6 the hat formation 4 of lid 2 has a flange section 13 bent around the top edge portion 18 of the container part 3 and extends a predetermined distance downwards along he external envelope surface 15 of container part 3.
To facilitate the swallowing of a capsule according to the invention the vacity 6 in lid 2 can be covered by a rounded lid portion 16 the free end edge 17 of which can be secured to the external envelope surface 15 of container part 3 by friction or by means of an adhesive.
