Controlled Collapse Bottle

Abstract

This invention is a squeeze bottle that forces all of the liquid toward the nozzle and then collapses in a controlled way to hold the liquid compressed toward the nozzle. Air is not allowed to enter the bottle to contact the liquid at all. The invention is comprised of a cap and a bottle. The cap has a nozzle with a one-way valve that lets the liquid out but no air in. The bottle is molded with variations in the thickness of the walls of the bottle. These variations cause the bottle to collapse in a controlled way so that the liquid is held against the cap at all times.

The container also prohibits the exposure of the liquid in the container to air. The container also collapses in a controlled way to accomplish this. Sometimes the container can also be designed to collapse in a way that the liquid is forced toward the nozzle and yet the container retains a shape capable of ...

AI Technical Summary

Benefits of technology

[0013]The object of the present invention is to provide a container that alleviates the drawbacks discussed in regards to the existing inventions. This new type of bottle will be inexpensive to manufacture and package in. This bottle will prohibit outside air from contacting the packaged liquid during dispensing and also during the life of the bottle. This will increase shelf life and sanitation as well as eliminating the problems associated with air-cured liquids such as clogged nozzles. This bottle will also be easy to use; it will not be necessary to shake the bottle or to store the bottle upside-down in order to use it.

Problems solved by technology

This valve allows liquid to escape when the bottle is squeezed, but does not allow air to enter the bottle.

The bottle would also have a thick non-collapsible base, but the walls would be thin near the base so they would start collapsing near the base first, and the collapse would work its way up the bottle.
