Foam generation assembly
First Claim
1. A foam generation assembly for a container comprising:
- a foam generator for producing foam;
a first channel for allowing either air or liquid into the foam generator; and
a second channel, the second channel capable for allowing either air or liquid into the foam generator, the second channel allowing air into the container if the first channel allows liquid into the foam generator and the second channel allowing liquid into the container if the first channel allows air into the foam generator.

Abstract
An improved foam generation assembly for a container includes a foam generator for producing foam. Two channels allow air or liquid into the foam generator. However, if one channel provides air for the foam generator, then the other channel provides liquid. A tube is attached to one channel, and extends near the base of the container. Thus, when the container is in is squeezed while in a generally upright position, liquid enters the tube and passes through a channel into the foam generator. Air enters the foam generator through the other channel. When the container is squeezed in a generally inverted position, air enters the tube and passes through a channel into the foam generator. Liquid enters the foam generator through the other channel. A valve is provided to seal the channels when foam is not being produced by the foam generator. A vent located in the exterior of the foam generation assembly allows air to return to the container.
