Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
204 words
Device for dispensing simultaneously under pressure two fluids which are separately packaged, said device comprising a container having two closed compartments, a fluid-containing jacket in each compartment, each of said jackets opening into a valve made of a flexible material at one end of said container, one of said compartments containing a liquefied pressurizing gas and opening into a valve made of a flexible material in said container end and the other compartment being unpressurized and opening into two valves made of a flexible material in the same end of the container, the single valve of said one compartment, the valve of the jacket in said other compartment, and one of the two valves of said other compartment forming a triangle congruent to a triangle formed by the valves of the two jackets the other valve of the other compartment, a dispensing cover adapted to be mounted on the base of the container and carrying three trocars adapted to enter and open said valves, said trocars forming a congruent triangle which may be brought into register with either of the triangles hereinbefore mentioned, a passageway in said cover connecting two of said trocars and an outlet for said cover connected to the other trocar.

Device for dispensing simultaneously under pressure two fluids which are separately packaged, said device comprising a container having two closed compartments, a fluid-containing jacket in each compartment, each of said jackets opening into a valve made of a flexible material at one end of said container, one of said compartments containing a liquefied pressurizing gas and opening into a valve made of a flexible material in said container end and the other compartment being unpressurized and opening into two valves made of a flexible material in the same end of the container, the single valve of said one compartment, the valve of the jacket in said other compartment, and one of the two valves of said other compartment forming a triangle congruent to a triangle formed by the valves of the two jackets the other valve of the other compartment, a dispensing cover adapted to be mounted on the base of the container and carrying three trocars adapted to enter and open said valves, said trocars forming a congruent triangle which may be brought into register with either of the triangles hereinbefore mentioned, a passageway in said cover connecting two of said trocars and an outlet for said cover connected to the other trocar.
Claim 3
Dependent Claim
41 words
Device as claimed in claim 1 in which the five valves are made of a rubberlike material, are substantially cylindrical in form with enlarged bases, are provided at their tops with a small collar, and are pierced by an axial hole.
Claim 4
Dependent Claim
17 words
Device as claimed in claim 1 in which the jackets are tubes of a flexible plastic material.
Claim 5
Dependent Claim
16 words
Device as claimed in claim 3 in which the tubes are snapped onto the corresponding valves.
Claim 6
Dependent Claim
26 words
Device as claimed in claim 1 in which the container is a circular cylinder and the cover is cylindrical and adapted to fit over the container.
Claim 7
Dependent Claim
24 words
Device as claimed in claim 1 in which the outlet is in the top of the cover and leads to a conventional dispensing spout.
Claim 8
Dependent Claim
38 words
Device as claimed in claim 1 in which the container carries a lateral projection and the cover is provided with two slots in its lateral surface parallel to the axis thereof which adapted tO cooperate with said projection.
Claim 9
Dependent Claim
32 words

Claim 10
Dependent Claim
121 words
Device for simultaneously dispensing two fluids, which device comprises: a container having two closed compartments, first and second compressible fluid-holding tubes, one in each compartment, said first tube being partly empty; a pressurizing fluid in the compartment containing said second tube; outlet means for said container; and means for first connecting said tubes together so that the pressure in the compartment containing said pressurizing fluid will force fluid from said first tube in said pressurized compartment into said second tube in the other compartment, and for subsequently connecting said pressurized compartment to said other compartment and said second tube to said container outlet, so that the contents of said second tube are urged through said container outlet by said pressurizing fluid.
