Abstract

Abstract The present invention is a dispenser for liquids or solids. It includes a main hollow housing with sidewalls, an open base and an open top. The base is open to receive an activator component and the top is at least partially open for dispensing material therethrough. There are also at least two sets of vertically aligned, horizontal housing ratchets located on the inside of the housing sidewalls. They are tapered downwardly so as to permit upward movement and restrict downward movement of a push plate located within the housing. There is also an activator component inserted into the bottom of the housing, which is reciprocally movable. It has at least two sets of vertically aligned horizontal ratchets extending upwardly and aligned against the inside of the housing sidewalls. The activator component has a flexible spring portion biasing the activator component downwardly. The activator component is reciprocally movable between a first, lower position and a second, higher position, such that when the activator component is moved from a first, lower position to a second, higher position, its ratchets move the push plate upwardly at least one ratchet length, and when the activator component is moved from the second position back to the first position, it is reset to advance the push plate upwardly upon a next reciprocation.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 246 words
A dispenser, comprising: (a) a main hollow housing having an inside and an outside and having sidewalls, a base and a top, said base being open to receive an activator component and said top being at least partially open for dispensing material therethrough; (b) at least two sets of vertically aligned, horizontal housing ratchets located on the inside of said housing sidewalls, said ratchets being tapered downwardly so as to permit upward movement and restrict downward movement; (c) a push plate located within said housing and adapted so as to only be movable upwardly past said housing ratchets; (d) an activator component inserted into the bottom of said housing, said activator component being vertically and reciprocally movable within said housing, and having at least two sets of vertically aligned horizontal ratchets extending upwardly and aligned against the inside of said housing sidewalls, said ratchets being tapered downwardly so as to permit upward movement of said push plate, said activator component having a flexible spring portion biasing said activator component downwardly, whereby said activator component is reciprocally movable between a first, lower position and a second, higher position such that when said activator component is moved from a first, lower position to a second, higher position, its ratchets move said push plate upwardly at least one ratchet length, and when said activator component is moved from said second position back to said first position, it is reset to advance said push plate upwardly upon a next reciprocation.
Claim 2
Dependent Claim 246 words
A dispenser, comprising: (a) a main hollow housing having an inside and an outside and having sidewalls, a base and a top, said base being open to receive an activator component and said top being at least partially open for dispensing material therethrough; (b) at least two sets of vertically aligned, horizontal housing ratchets located on the inside of said housing sidewalls, said ratchets being tapered downwardly so as to permit upward movement and restrict downward movement; (c) a push plate located within said housing and adapted so as to only be movable upwardly past said housing ratchets; (d) an activator component inserted into the bottom of said housing, said activator component being vertically and reciprocally movable within said housing, and having at least two sets of vertically aligned horizontal ratchets extending upwardly and aligned against the inside of said housing sidewalls, said ratchets being tapered downwardly so as to permit upward movement of said push plate, said activator component having a flexible spring portion biasing said activator component downwardly, whereby said activator component is reciprocally movable between a first, lower position and a second, higher position such that when said activator component is moved from a first, lower position to a second, higher position, its ratchets move said push plate upwardly at least one ratchet length, and when said activator component is moved from said second position back to said first position, it is reset to advance said push plate upwardly upon a next reciprocation.
Claim 3
Dependent Claim 34 words
The dispenser of claim 1 wherein said top of said housing is open sufficiently to dispense a cake material and said push plate includes means for holding a portion of a cake material therein.
Claim 4
Dependent Claim 24 words
The dispenser of claim 1 wherein said top of said housing has a dispensing orifice adapted to receive a neck of a material pouch.
Claim 5
Dependent Claim 30 words
The dispenser of claim 3 further including a dispensing pouch having a neck and compressible body, said pouch neck being located in said orifice of the top of said housing.
Claim 6
Dependent Claim 27 words
The dispenser of claim 1 wherein said push plate is partially bifurcated to enhance its insertion into said housing and to enable reusing of said push plate.
Claim 7
Dependent Claim 41 words
The dispenser of claim 10 wherein said at least two sets of vertically aligned, horizontal housing ratchets is four sets of vertically aligned, horizontal housing ratchets and they are located in opposite pairs such that the activator component ratchets nest therebetween.
Claim 8
Dependent Claim 30 words
The dispenser of claim 6 wherein said activator component includes a wider lower portion which extends beyond the bottom of said housing to create a vertical handle for a user.
Claim 9
Dependent Claim 21 words
The dispenser of claim 1 wherein said activator component also includes a stanchion to prevent accidental overinsertion of said push plate.
Claim 10
Dependent Claim 34 words
The dispenser of claim 1 wherein said activator component ratchets are flanged and said housing ratchets are winged to receiver said flanges so as to enhance the reciprocal functioning and strength of the device.
