Abstract
Abstract A device comprising a jacket having a valved end and holding a first product, a container holding a second product slidable within said jacket and in sealing contact with the jacket walls, means for propelling said container toward said valved end, and a rod positioned to open an orifice in said container as it approaches the valved end of said jacket.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
154 words
A device for storing two products separately and dispensing them simultaneously, which device comprises an outer jacket, a dispensing valve at one end of said jacket, an inner container positioned within said jacket in slidable sealing contact with the walls of said jacket and with the end of said container nearest said valve defining an orifice, a plug frictionally retained in said orifice, means operable from outside said jacket for driving said container toward the valved end of said jacket, a stationary substantially axial rod between said orifice and the valved end of said jacket having an end positioned to drive said plug into said container when said container approaches the valved end of said jacket, and a cover dimensioned to close said container orifice and slidably and sealingly mounted on said rod between rod end and the valved end of said jacket so as to close said orifice when it reaches said cover.
Claim 2
Independent Claim
154 words
A device for storing two products separately and dispensing them simultaneously, which device comprises an outer jacket, a dispensing valve at one end of said jacket, an inner container positioned within said jacket in slidable sealing contact with the walls of said jacket and with the end of said container nearest said valve defining an orifice, a plug frictionally retained in said orifice, means operable from outside said jacket for driving said container toward the valved end of said jacket, a stationary substantially axial rod between said orifice and the valved end of said jacket having an end positioned to drive said plug into said container when said container approaches the valved end of said jacket, and a cover dimensioned to close said container orifice and slidably and sealingly mounted on said rod between rod end and the valved end of said jacket so as to close said orifice when it reaches said cover.
Claim 3
Dependent Claim
54 words
A device as claimed in claim 1 in which said driving in means comprises a rupturable barrier near the end of said jacket remote from said valve which separates from the remainder of said jacket, a chamber filled with a gas under pressure, and means operable from outside said jacket for rupturing said barrier.
Claim 4
Dependent Claim
87 words
A device as claimed in claim 2 in which the pressure of the gas in said chamber is sufficient to overcome the frictional resistance between said container and jacket and drive said container toward the valved end of said jacket when said barrier is ruptured at a speed permitting the contents of said container to fall into said jacket between the time at which said plug is driven out of said orifice by said rod end and that at which said orifice is closed by said cover.
Claim 5
Dependent Claim
19 words
A device as claimed in claim 2 in which said gas is under a gauge pressure of 1.5 kg./cm.2.
Claim 6
Dependent Claim
22 words
A device as claimed in claim 2 in which said cover is shaped to enter, but incapable of passing through said orifice.
