摘要:
Exemplary embodiments of dispensers and refill units are disclosed herein. An exemplary refill unit for a soap, sanitizer or lotion includes a non-collapsing container. The non-collapsing container includes a neck. An annular projection is located at least partially on the neck. A one-way valve is located proximate the annular projection. The one-way valve allows air to flow into the non-collapsing container once the vacuum pressure in the container reaches the cracking pressure of the one-way valve and the one-way valve prevents liquid from flowing out of the annular projection. In addition, a pump for pumping the contents of the container out of the container is also included.

Exemplary embodiments of pumps, refill units and dispensers are disclosed herein. Some embodiments include a container for holding a fluid and a pump housing secured to the container. The pump housing includes an annular collar for securing the pump housing to the container. The pump housing includes an air chamber and a vent valve located at least partially within the air chamber. One or more air passageways are provided in the collar for providing air to the air chamber. A compressible liquid pump chamber is also located in the housing. The exemplary embodiment includes a liquid inlet valve for allowing liquid to flow from the container into the compressible pump chamber; and a liquid outlet valve located downstream of the pump chamber.

A foam dispensing pump container having a suction inlet capable of introducing a large amount of external air while preventing ingress of water and foam certainly. In the foam dispensing pump container, a suction inlet 45 is opened to an opposite side of a discharging outlet 43 of the nozzle member 4. The suction inlet 45 is communicated with an air course formed between an inner cylinder 41and an outer cylinder 42 through a through hole 46. A skirt shaped cover portion 47 is formed to extend downwardly from an outer circumferential edge of the ceiling of the nozzle member 4 to a level lower than the suction inlet 45. In order to divide and shut off an inner space of the skirt shaped cover portion 47 (i.e., a space between an inner face of the cover portion 47 and the outer cylinder 42), at least one pair of partitions 49 are formed on both sides of the suction inlet 45 in the circumferential direction of the nozzle member 4.
