Abstract
Abstract A dispensing system for use with a container of a product to be dispensed, in which the system includes a combination fluid pressure supply and regulator unit for detachable association with a dispenser unit received on a product container, in which the combination dispenser unit is removably locked in position engaging the dispenser unit associated with the container. The combination supply and regulator unit includes a pressure regulator unit and a discharge valve which is actuated to supply pressure to the container only when the supply and regulator unit is locked in position of use within the dispenser. Removing the supply and regulator unit closes the valve therein, and the combination unit may then be used in association with another similar container and dispenser. The dispenser includes a product discharge means including a dip tube, a product outlet, a valve for controlling product flow, and a valve for preventing escape of pressurizing fluid from the container.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
183 words
A combination fluid pressure supply and regulator unit for detachable engagement with a dispenser associated with a container desired to be pressurized, said unit comprising a chamber for holding a supply of pressurizing fluid at a first, higher pressure, means at least partially defining a second, lower pressure chamber, a regulator passage extending between said higher and lower pressure chambers, said lower pressure chamber having a discharge passageway associated therewith, said discharge passageway terminating in a discharge outlet, and a discharge valve within said unit for controlling fluid flow through said outlet, said means defining a portion of said lower pressure chamber being movable in response to the pressure within said chamber and further including a valve for opening and closing said regulator passage between said chambers, and means for detachably locking said unit in position adjacent dispenser means associated with a container for supplying pressurizing fluid thereto, said discharge valve being normally closed and adapted to be opened by engagement of a portion thereof with a portion of said dispenser means when said unit is held in position by said locking means.
Claim 2
Dependent Claim
183 words
A combination fluid pressure supply and regulator unit for detachable engagement with a dispenser associated with a container desired to be pressurized, said unit comprising a chamber for holding a supply of pressurizing fluid at a first, higher pressure, means at least partially defining a second, lower pressure chamber, a regulator passage extending between said higher and lower pressure chambers, said lower pressure chamber having a discharge passageway associated therewith, said discharge passageway terminating in a discharge outlet, and a discharge valve within said unit for controlling fluid flow through said outlet, said means defining a portion of said lower pressure chamber being movable in response to the pressure within said chamber and further including a valve for opening and closing said regulator passage between said chambers, and means for detachably locking said unit in position adjacent dispenser means associated with a container for supplying pressurizing fluid thereto, said discharge valve being normally closed and adapted to be opened by engagement of a portion thereof with a portion of said dispenser means when said unit is held in position by said locking means.
Claim 3
Dependent Claim
43 words
A combination unit as defined in claim 1 in wHich said higher pressure chamber comprises a body, a cover therefor, sealing means disposed between said body means and said cover means and means for piercing a cartridge having a supply of fluid therein.
Claim 4
Dependent Claim
38 words
A combination unit as defined in claim 1 in which said means responsive to said pressure comprises a piston and in which a portion of said lower pressure chamber comprises a cylinder surrounding said piston in fluid-tight relation.
Claim 5
Dependent Claim
74 words
A combination unit as defined in claim 1 in which said combination unit includes a regulator body and in which said low pressure chamber is disposed within said body, said outlet passage extends through a face of said body, in which said discharge valve is disposed within said passage and includes a stem extending outwardly from said body for contacting an actuator associated with said dispenser means for supplying pressurizing fluid to a container.
Claim 6
Dependent Claim
134 words
A product dispensing system which includes a combination fluid pressure supply and regulator unit as defined in claim 1, and, detachably associated therewith, a dispenser means for supplying pressurizing fluid to a container, said dispenser means including means for reception of a container in fluid-tight relation, passage means for supplying said fluid to the interior of said container, product discharge means for discharging the contents of said container, and means for controlling the flow of product in said product discharge means, said means for supplying said fluid to said container including locking means for engaging said locking means on said combination supply and regulator unit, and actuator means for opening said discharge valve when said combination unit is in a locked position in association with said means for supplying said fluid to said container.
Claim 7
Dependent Claim
47 words
A combination as defined in claim 5 in which said dispenser includes valve means associated with said passage means for supplying said fluid to said container, said valve means permitting passage of fluid into said container in one direction and restricting flow therethrough in an opposite direction.
Claim 8
Dependent Claim
89 words
A combination as defined in claim 5 in which said dispenser means for supplying said fluid to said container has an opening therein of a shape corresponding to the shape of a portion of said supply and regulator unit, and in which said locking means are adapted to register with said combination supply and regulator unit in a single position thereof, and in which said dispenser means includes manually operable means for holding said locking means in a locked position and for permitting release thereof to an unlocked position.
Claim 9
Dependent Claim
91 words
A combination as defined in claim 5 in which said locking means on said combination fluid pressure supply and regulator unit comprise a generally U-shaped locking portion having two leg portions, a bight extending therebetween and defining an opening, and in which said locking means on said dispenser comprises an at least partially manually operable means having a portion thereof of a shape complementary to said opening defined by said legs and said bight, for positioning therein to retain said combination supply and regulator unit in locked association with said dispenser.
