Liquid dispensing device

Abstract

A liquid dispensing device includes a resilient receptacle for receiving a liquid and attached to a cover device and having an accordion structure for providing a resilience to the receptacle and for forcing the liquid out of the receptacle, and a controlling device for controlling the liquid to flow out of the cover device, the receptacle includes two or more folds each having an upper peripheral wall inclined downwardly and outwardly, and a lower peripheral wall inclined downwardly and inwardly and more inclined relative to the upper peripheral wall, for allowing the peripheral walls of the folds to be folded toward each other to a compact folding structure.

Description

[0001]The present invention is a continuation-in-part of U.S. patent application Ser. No. 11 / 827,586, filed 11 Jul. 2007, pending.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a liquid dispensing device, and more particularly to a liquid dispensing device including a resilient or vacuum and disposable carriage or bladder or receptacle for containing the liquid or viscous fluid and for forcing the liquid or viscous fluid out of the resilient receptacle and for allowing the liquid dispensing device to be erectly disposed without being disposed up side down and for allowing the disposable receptacle to be changed or replaced with new ones.[0004]2. Description of the Prior Art[0005]Typical liquid dispensing devices comprise a casing disposed in an outer housing for containing the liquid or viscous fluid, in which the casing and the outer housing should be disposed up side down for allowing the liquid or viscous fluid to flow downwardly ...

AI Technical Summary

Benefits of technology

"The present invention is a liquid dispensing device that includes a resilient or vacuum receptacle for containing liquid and a controlling device for controlling the liquid to flow out of the device. The device can be erectly disposed on a table or the like without being disposed up side down. The receptacle has a foldable upper peripheral wall and a lower peripheral wall that can move upwardly and downwardly as the liquid is consumed. The cover device has a compartment for receiving the liquid forced out of the receptacle and includes a check valve and a tube with a valve member for selectively opening and closing the orifice of the bottom wall. The device also includes a knob with a conduit for allowing the liquid to flow out through the mouth, a spring member for biasing the knob, and a container for receiving the receptacle. The technical effects of the invention include providing a convenient and efficient liquid dispensing device that can be easily moved and replaced with new receptacles."

Problems solved by technology

However, it is required to attach or to mount the casing and the outer housing onto the supporting wall, and it will be inconvenient for the users to mount the casing and the outer housing onto the supporting wall by themselves.

However, after the liquid or viscous fluid has been completely flown out of the casing or after the casing has been emptied, the casing and / or the outer housing or the whole typical liquid dispensing devices should be discarded and may not be recycled or changed or replaced with the other casings that are filled with liquid or viscous fluid.
