Abstract
Abstract A container of the plastic ''''squeeze bottle'''' type having two compartments which are in communication through a reduced neck portion or restriction which is closed by a tubular stem on a screw cap when the bottle is closed thereby to keep two liquid components separated until they are to be commingled at the time of dispensing. When the liquids are to be dispensed, the cap is removed and reversed to open the reduced neck portion to allow the liquids to become commingled, whereupon the resultant mixture may be dispensed through the stem of the cap by squeezing the container.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
126 words
A storage and dispensing container comprising: a hollow body formed with upper and lower compartments separated by a portion of reduced diameter forming a restricted passage between said compartments, said hollow body having an opening at one end opening into one of the compartments; a reversible cap assembly releasably attached to said opening preventing commingled flow through said opening and an alternative position for permitting commingled flow through said opening; said cap assembly having an elongate portion extending through said restricted passage; an enlargement on said elongate portion sized to contact against and seal within said restricted passage; and, a removable cover on said cap assembly closing said cap assembly when said cap assembly is releasably attached to said opening for preventing flow through said opening.
Claim 2
Dependent Claim
126 words
A storage and dispensing container comprising: a hollow body formed with upper and lower compartments separated by a portion of reduced diameter forming a restricted passage between said compartments, said hollow body having an opening at one end opening into one of the compartments; a reversible cap assembly releasably attached to said opening preventing commingled flow through said opening and an alternative position for permitting commingled flow through said opening; said cap assembly having an elongate portion extending through said restricted passage; an enlargement on said elongate portion sized to contact against and seal within said restricted passage; and, a removable cover on said cap assembly closing said cap assembly when said cap assembly is releasably attached to said opening for preventing flow through said opening.
Claim 3
Dependent Claim
95 words
The invention of claim 1 wherein said cap assembly is threaded and said opening is cooperatively threaded permitting reversal of said cap assembly, and further including: a passage through said elongate portion of such length as to extend from said opening into the more remote of said compartments; said cap assembly having a second passage therethrough extending to the less remote of said compartments; said first and second passages providing ingress to said compartments permitting introduction of two fluids to said compartments after said cap assembly is in the position preventiNg flow through said opening.
Claim 4
Dependent Claim
17 words
The invention of claim 1 wherein said enlargement has an O-ring seal means on the exterior thereof.
Claim 5
Dependent Claim
97 words
The invention of claim 1 wherein said cap assembly includes: a cylindrical body having threads at both ends thereof; a centrally positioned elongate portion which has a hollow passage; a transverse member closing said cylindrical body and connected to said elongate portion; a second passage through said transverse member; a check valve in one of said passages; one of said passages being of sufficient length to communicate with the more remote of said compartments and the other communicating with the remaining compartment; and, said cover closing both of said passages in the vicinity of said transverse member.
Claim 6
Dependent Claim
39 words
The invention of claim 4 including in the passage having the check valve, an enlarged portion in the passage; a valve member; a spring; and, a shoulder defined by the enlargement and said spring forcing said valve member thereagainst.
