Abstract
A fluid dispenser which includes a container having a collapsible, recoverable portion and a valve assembly connected thereto which includes a flexing flap for closing and opening an air opening extending into the container for permitting air to enter the container, the air being compressed and used to dispense fluid from the container through a valve nozzle in response to the actuation of the collapsible, recoverable portion.
Claims2
In a fluid dispenser having a container provided with a bellowed wall portion to form a chamber, and which is capable of compressing and recovering in response to the application of a force thereon, a molded valve assembly connected to said container, which comprises:
- a lower member having a base provided with an aperture therein,
- a dispensing tube communicating with said aperture,
- a flex type flap member integrally connected to and extending from said base in a substantially similar plane, said flap member having a thickness relatively smaller than that of the base, and
- an upper member having a body portion removably connected to said base and which forms a dispensing nozzle when connected to said base, a head portion extending from said body portion, and a formed air opening extending through said head portion for communication with the chamber of the container, said air opening being located in spacial relationship with the container chamber such that one side of the flex type flap member is in normally intimate contact with the formed air opening and the other side of the flap member is exposed to the container chamber, the member capable of being moved from said air opening in response to external air passing through said air opening into the container and being moved against said air opening upon compressed air being generated within the container for forcing fluid from the chamber through the dispensing tube and dispensing nozzle.
