DETAILED DESCRIPTION OF THE DRAWINGS
With reference to the drawings, a digestible pharmaceutical capsule in accordance with the invention is designated generally by the reference numeral 10. The capsule 10 is in the form of a hard shell gelatine capsule comprising, broadly, a capsule body 12, a diaphragm 14 and an end cap 16. The capsule 10 defines a first chamber 18 and a second chamber 20 for holding substances therein.
The capsule body 12 has an open end 22 and a closed end 24 and a cylindrical side wall 26 extending between the ends. The side wall 26 is resiliently deformable and defines a circumferential indent which defines a first locking formation in the form of a circumferential inwardly-extending ridge 28 at an inner side of the indent and a second locking formation in the form of a corresponding circumferential outwardly-facing groove 30.
The diaphragm 14 is located within the capsule body and has an open end 32, a closed end 34 and a cylindrical side wall 36 which extends between the ends. The cylindrical side wall of the diaphragm is resiliently deformable and defines a circumferential indent providing a locking formation in the form of a circumferential outwardly-facing groove 38 and a corresponding inwardly-extending circumferential ridge 40 at an inner side of the indent. The end cap 16 has a closed end 42, an open end 44 and a resiliently deformable cylindrical side wall 46 which extends between the ends. The cylindrical side wall 46 defines a circumferential indent which defines a locking formation in the form of an inwardly-extending circumferential ridge 50 and a corresponding outwardly-facing groove 48 at an outer side of the indent.
In use, the locking formations in the form of circumferential ridges and complementary circumferential grooves provide for location and locking of the diaphragm to an inner side of the capsule body location and locking of the end cap to an outer side of the capsule body by engagement of the complementary locking formations wherein the ridges are seated within the complementary grooves.
With reference to Figures 4A and 4B, the invention extends to a method of manufacturing the capsule 10 which includes providing the capsule body 12, the diaphragm 14 and the end cap 16, telescopically inserting the diaphragm into the capsule body (see Figure 4A) until the locking formations are mechanically locked by engagement of the locking formations when the circumferential ridge 28 of the capsule
body is received and seated within the circumferential groove 38 of the diaphragm (see Figure 4B) and telescopically locating the end cap 16 over the open ends of the capsule body and the diaphragm (see Figure 4B) and pushing the end cap onto the capsule body until the circumferential ridge 50 of the end cap is received and seated within the circumferential groove 30 of the capsule body. In this manner, the diaphragm is mechanically locked to an inner side of the capsule body while the end cap is mechanically locked to an outer side of the capsule body.
The joint formed by the overlapping walls and engaged locking formations of the diaphragm, capsule body and end cap is braced and thus strengthened by the locking of the end cap onto the capsule body.
With reference to Figures 5A - 5C, resistance to displacement of the diaphragm relative to the capsule body when the locking formation of the diaphragm is engaged with the locking formation of the capsule body, is illustrated. As can be seen in Figures 5B and 5C, displacement of the diaphragm in direction "A" relative to the capsule body in response to a force being applied to the diaphragm in direction "A", results in a build up of internal hoop stress resisting movement of the diaphragm relative to the capsule body and causing deformation of the diaphragm. The separation force is resisted by the engagement of the locking formations which, as a result, contribute significantly to maintaining the structural integrity of the capsule. The Applicant envisages that the lower chamber 20 will typically have a gas and/or a liquid contained therein which is prone to expansion at elevated temperatures while the capsule itself may be subjected to lower ambient pressures, for example, during air travel. This may result in a pressure differential between ambient pressure and internal pressure within a chamber of the capsule which may tend to exert a force on the diaphragm for displacement of the diaphragm relative to the capsule body in a direction for separating the diaphragm from the capsule body thereby potentially compromising the hermetic seal of the chamber 20. With reference to Figure 6 of the drawings, another embodiment of a capsule in accordance with the invention is designated by the reference numeral 100. The capsule
100 is similar to the capsule 10, with the only difference being that the capsule 100 comprises three chambers 70.1 , 70.2 and 70.3 defined by two diaphragms 14 which are mechanically locked by complementary locating formations to an inner side of an elongated capsule body 112. In Figure 6, features of the capsule 100 which are the same as and/or similar to features of the capsule 10, are designated by the same and/or similar reference numerals.
The locking formations of the capsules 10 and 100 assist in maintaining the structural integrity of the capsules and also assist in ensuring uniformity in the structure of capsules. More specifically, the locking formations provide for uniform location of the diaphragm(s) and end cap relative to the capsule body of each capsule in a batch manufacturing process thereby ensuring that the volumes of the chambers remain constant throughout the batch. This is a significant benefit for ensuring optimal volumetric consistency in the chambers of capsules manufactured in a batch process. It will be appreciated that diaphragms inserted too deep into a capsule body will besides reducing the volume of the chamber for holding a substance, also affect the structural integrity of the capsule as the pressure within the chamber is increased with a reduction in volume.
