Abstract:
A dispensing capsule (2) comprises a capsule body (4) having a first end (6) and a second end (8); a first cavity (14) and a second cavity (16) with a dividing member (18) between them within the capsule body (4), both cavities having an opening at the first end of the capsule body; a peripheral wall (24) at the first end (6) of the capsule body (4); and a flexible seal (30) bonded to the peripheral wall at the first end and to the dividing member so as to seal the contents of the first and second cavities from each other. The seal (30) is bonded less strongly to the dividing member (18) than to the peripheral wall (24). On an increase of pressure within the two cavities, the bond between the seal (30) and the dividing member (18) will eventually break, permitting the contents of the first cavity (14) to at least partly mix with the contents of the second cavity (16) while the bond between the seal (30) and the peripheral wall (24) remains intact. A burst pin (20,22) is also disposed within each cavity for breaking the bond between the seal (30) and at least some of the peripheral wall (24).
