Abstract
Abstract A dispenser designed to mix a relatively viscous concentrate contained in a disposable container removably mounted therein with a diluent and then dispense the resultant diluted mixture. A peristaltic type pump is used on a flexible conduit which is removably connected between the disposable container and a mixing nozzle assembly. The mixing nozzle assembly includes a valve arrangement for controlled mixing of the diluent with the concentrate in proper porportions immediately prior to exiting from the dispenser.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
189 words
A dispenser of the type designed to mix liquids of different densities, said dispenser of the type designed to mix liquids of different densities, said dispenser comprising: a. a removably mounted dispensing container; b. a pump assembly positioned in communicating relation with said dispensing container; c. conduit means attached to said dispensing container and positioned to operably engage said pump assembly, said pump assembly is mounted to be movable into and out of operable engagement with said conduit means, such that said dispensing container and said conduit means are removable from said dispenser and d. mixing means for combining the liquids prior to dispensing: said pump assembly comprising a rotatable shaft including a flange substantially helically mounted about the periphery thereof and, a backup plate operatively positioned to engage said conduit means in supporting relation thereto; said shaft and said backup plate being pivotally mounted so as to be movable into and out of operative engagement with said conduit means; said flange arranged to continuously depress successive portions of said conduit means during rotation of said shaft, whereby liquid from said dispensing container is forced through said conduit means.
Claim 2
Dependent Claim
189 words
A dispenser of the type designed to mix liquids of different densities, said dispenser of the type designed to mix liquids of different densities, said dispenser comprising: a. a removably mounted dispensing container; b. a pump assembly positioned in communicating relation with said dispensing container; c. conduit means attached to said dispensing container and positioned to operably engage said pump assembly, said pump assembly is mounted to be movable into and out of operable engagement with said conduit means, such that said dispensing container and said conduit means are removable from said dispenser and d. mixing means for combining the liquids prior to dispensing: said pump assembly comprising a rotatable shaft including a flange substantially helically mounted about the periphery thereof and, a backup plate operatively positioned to engage said conduit means in supporting relation thereto; said shaft and said backup plate being pivotally mounted so as to be movable into and out of operative engagement with said conduit means; said flange arranged to continuously depress successive portions of said conduit means during rotation of said shaft, whereby liquid from said dispensing container is forced through said conduit means.
Claim 3
Dependent Claim
33 words
A dispenser as in claim 1 wherein said dispenser further comprises movably mounted piercing means positioned adjacent said dispensing container and serving to puncture said dispensing container when operatively positioned within the dispenser.
Claim 4
Dependent Claim
161 words
A dispeNser of the type designed to mix liquids of different densities, said dispenser comprising: a. a removably mounted dispensing container; b. a pump assembly positioned in communicating relation with said dispensing container; c. Conduit means attached to said dispensing container and positioned to operably engage said pump assembly, and d. mixing means for combining the liquids prior to dispensing: said mixing means comprising a valve assembly for adjustably regulating the flow of at least one of said liquids and nozzle means positioned in communicating relation with both said valve assembly and said dispensing container; said valve assembly comprising a valve seat and a valve element adjustably mounted within said assembly in cooperating relation to said valve seat; said valve assembly positioned in communicating relation to a source of said one liquid; whereby the flow of said one liquid is regulated by said valve assembly dependent upon the rate of flow of at least one other liquid through said nozzle means.
Claim 5
Dependent Claim
161 words
A dispeNser of the type designed to mix liquids of different densities, said dispenser comprising: a. a removably mounted dispensing container; b. a pump assembly positioned in communicating relation with said dispensing container; c. Conduit means attached to said dispensing container and positioned to operably engage said pump assembly, and d. mixing means for combining the liquids prior to dispensing: said mixing means comprising a valve assembly for adjustably regulating the flow of at least one of said liquids and nozzle means positioned in communicating relation with both said valve assembly and said dispensing container; said valve assembly comprising a valve seat and a valve element adjustably mounted within said assembly in cooperating relation to said valve seat; said valve assembly positioned in communicating relation to a source of said one liquid; whereby the flow of said one liquid is regulated by said valve assembly dependent upon the rate of flow of at least one other liquid through said nozzle means.
Claim 6
Dependent Claim
28 words
A dispenser as in claim 3 wherein said valve element is threadedly connected within said valve assembly so as to be adjustably positioned relative to said valve seat.
Claim 7
Dependent Claim
80 words
A dispenser as in claim 3 further comprising an orifice arranged in intercommunicating relation between said valve assembly and said nozzle means, said orifice being of sufficient size to form a jet flow of said one liquid into said nozzle means, said nozzle means comprising a first channel defining the flow of another of said liquids, said orifice arranged substantially perpendicular to said first channel, whereby turbulence is created by the joining of said one liquid to said other liquid.
Claim 8
Dependent Claim
46 words
A dispenser as in claim 3 wherein said nozzle means comprises: a first flow defining channel, a second channel communicating with said first channel and arranged substantially perpendicular thereto, whereby turbulence is created by a flow of liquid from said first channel to said second channel.
Claim 9
Dependent Claim
122 words
A dispenser of the type designed to mix liquids of different densities, said dispenser comprising: a. a removably mounted dispensing container; b. a pump assembly positioned in communicating relation with said dispensing container; c. conduit means attached to said dispensing container and positioned to operably engage said pump assembly; and d. mixing means for combining the liquids prior to dispensing: said pump assembly including a rotatable shaft, an outwardly extending flange helically arranged along the periphery of said shaft and a backup plate positioned in cooperating relation to said shaft, said shaft and said backup plate movably mounted relative to said pump assembly so as to move said shaft and said backup plate into and out of operative relation to each other.
Claim 10
Dependent Claim
122 words
A dispenser of the type designed to mix liquids of different densities, said dispenser comprising: a. a removably mounted dispensing container; b. a pump assembly positioned in communicating relation with said dispensing container; c. conduit means attached to said dispensing container and positioned to operably engage said pump assembly; and d. mixing means for combining the liquids prior to dispensing: said pump assembly including a rotatable shaft, an outwardly extending flange helically arranged along the periphery of said shaft and a backup plate positioned in cooperating relation to said shaft, said shaft and said backup plate movably mounted relative to said pump assembly so as to move said shaft and said backup plate into and out of operative relation to each other.
Claim 11
Dependent Claim
38 words
A dispenser as in claim 7 wherein said pump assembly further includes unclamping means comprising a reciprocally mounted plate positioned to move said shaft and said backup plate into and out of operative engagement with said conduit means.
