ABSTRACT:
A valved squeeze bottle for viscous products has a valve comprising two plastic parts cooperatively forming a chamber into which the viscous product can be squeezed by squeezing the squeeze bottle, to elastically separate the parts which together form a sleeve valve opened by the separation of the parts and which recloses when the bottle squeeze pressure is released so the parts return, one of the parts forming a check valve permitting entrance of air into the bottle. The squeeze bottle and the valve parts are made of elastically deformable plastic which after being deformed, springs back to its original shape.
