Abstract: A squeeze bottle forces substantially all of the liquid to be dispensed toward a top of the bottle. A valving arrangement reduces or eliminates a likelihood of air contacting the liquid to be dispensed. A top cap has a nozzle with a one-way valve allowing liquid to leave a liquid bag. A bottom cap has a one-way valve allowing air to enter an airbag. The liquid bag and the airbag are positioned within a sealed third chamber. The liquid bag and the airbag have a controlled interaction within the sealed third chamber, which results in substantially complete emptying of the liquid bag by squeezing the 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.

Abstract: This invention is a squeeze bottle that forces all of the liquid to be dispensed at the top of the bottle. The invention also prohibits air from contacting the liquid to be dispensed. This bottle is composed of the following: A top cap has a nozzle with a one-way valve allowing liquid to leave the container. A bottom cap employs a one-way valve that allows air to enter an airbag. The caps attach to the body of the squeeze bottle. The liquid is in a bag that is referred to as the first chamber. This first chamber is airtight with the only egress for the liquid being through the top one-way valve. The bottom chamber is an airbag distinct from the liquid bag. This second bag forms a distinct second chamber that is also airtight. The second chamber communicates exclusively to the outside air, only allowing air in through the one-way valve at the bottom.
