  • Patent number: 10450117
    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.

  • Patent number: 9970431
    Abstract: A hand-held pump apparatus has a peristaltic pump head and a container for a liquid to be dispensed. The pump head has a rotatable peristaltic pump member and a flexible dispensing tube in fluid connection with the inside of the container. A finger-actuated trigger is arranged to drive the peristaltic pump member when actuated so as to cause the peristaltic pump member to turn and pump fluid through the dispensing tube. The pump head has a thumb hole disposed through it, the thumb hole being disposed within an area around which the peristaltic pump member turns when actuated.

  • Patent number: 9790939
    Abstract: A pump apparatus (1) comprises a pump head (2) and a container (20) for a liquid to be dispensed. The pump head (2) has a flexible dispensing tube (4) in fluid connection with the inside of the container (20). The fluid connection between the dispensing tube (4) and the inside of the container (20) is provided by a supply tube (28) which co-operates with the dispensing tube (4) to provide a non-return valve function. An end (48) of the supply tube (28) is disposed within an end of the dispensing tube (4) and the non-return valve function is provided by a hole (46) through a side wall of the supply tube (28) in a region where the dispensing tube (4) overlaps the supply tube, whereby the dispensing tube (4) provides a seal over the hole (46) to prevent ingress of fluid when the internal pressure is lower than the external pressure. Another aspect of the invention provides a container (20) for use in the pump apparatus.
