Abstract
Abstract Storage and dispensing device comprises a storage container for holding one liquid under pressure and a dispensing container in which another liquid is stored. The two containers are connected by a connecting tube along which one of the containers is axially slidable. Such sliding movement opens valves on both containers, so that liquid from the pressurized storage container is driven into the dispensing container, which is then separated from the tube and storage container and used as a dispenser.

Total Claims: 11
Claim 1
Independent Claim
229 words
In combination with a pair of storage containers for storing separately two products which are to be dispensed simultaneously, each of said containers being provided with a valve having an externally projecting outlet tube which opens said valve when depressed, and each being provided with an external abutment, the improved means for connecting said containers which comprises: a rigid cylindrical connecting member having snap fastening means at one end thereof shaped and dimensioned to snap over the abutment means on one of said containers, and removable fastening means at the other end of said connecting member for detachably engaging the abutment means on the other of said containers, said connecting member serving to hold said containers in a fixed position relative to each other when said fastening means are in engagement with said abutments, but to permit said containers to be forced toward each other along the axis of said connecting member when said removable fastening means is detached, and a transfer spigot slidably mounted inside the connecting member between said containers, said spigot simultaneously engaging the outlet tubes of the two valves of the two containers and defining a duct bringing said outlet tubes into communication with each other when said containers occupy said fixed position, said spigot being dimensioned to depress said outlet tubes and thereby open said valves when said containers are forced toward each other.

Claim 3
Dependent Claim
49 words
The combination claimed in claim 1 in which one of said containers is a storage container holding one of said products under the pressure of a pressurizing gas and the other is a dispensing container holding the other product under a pressure less than that in said storage container.
Claim 4
Dependent Claim
25 words
Device as claimed in claim 2 essentially characterized by the fact that the spigot is conical in shape with its base toward the dispensing container.
Claim 5
Dependent Claim
44 words
Device as claimed in claim 2 in which the part of the spigot near the storage container is provided with a projection adapted to abut the wall of said storage container after movement of the spigot for a limited distance within the connecting member.
Claim 6
Dependent Claim
17 words
Device as claimed in claim 2 in which the pressurizing gas in the storage contaiNer is nitrogen.
Claim 7
Dependent Claim
25 words
Device as claimed in claim 2 in which the storage container holds an oxidation hair dye whereas the dispensing container holds a liquid oxidizing composition.
Claim 8
Dependent Claim
46 words
Device as claimed in claim 2 in which the storage container holds, in addition to the liquid to be dispensed a certain quantity of a liquefied gas other than the insoluble pressurizing gas, and the dispensing container holds the liquid to be dispensed under atmospheric pressure.
Claim 9
Dependent Claim
88 words
Device as claimed in claim 2, in which the storage container holds only one of the liquid products to be dispensed and an insoluble non-liquefied pressurized gas and the dispensing chamber holds a flexible fluid-tight bag attached to the valve of said dispensing container, said bag holding the other product to be dispensed, but having an inner volume sufficient to also contain the products initially held in the storage container, said flexible bag being subjected to an external pressure inside the dispensing container due to a pressurizing gas.
Claim 10
Dependent Claim
50 words
Device as claimed in claim 2 in which the storage and dispensing containers are generally cylindrical in form and each has at one end a conical portion supporting a cap in which its valve is mounted, said cap being crimped to the end of the lateral wall of the container.
Claim 11
Dependent Claim
29 words
Device as claimed in claim 9, in which the connecting member is slidable with respect to the dispensing container and rests on the conical portion of the storage container.
