Abstract
A dispenser for comestibles having a container which is supported by a casing. The casing has a frame there which, in turn, supports an axially movable ratchet mechanism. The ratchet is moved by an actuator which is operatively interconnected with a handle each manipulation of which will advance the ratchet by one tooth pitch towards the container. The container has a piston head formed on its bottom wall and engaged by the ratchet end. The advance of the ratchet, will cause the bottom of the container to move into the container so as to displace an equal volume comestible and force the displayed quantity of comestible out of a container dispensing orifice.
Claims4
An apparatus for discretely dispensing predetermined quantities of a comestible comprising:
- a. a container having an open bottom and a quantity of comestible disposed therein;
- said container having a dispensing orifice;
- a piston head having a substantially conical shape positioned along the open bottom of said container in order to retain the comestible within the container;
- a means for moving said piston head upwardly into the container;
- b. a casing having said container removably mounted thereon;
- a frame slidably received within said casing, said frame positioned immediately below said piston head to provide support therefor, an elongate ratchet member axially and slidably arranged in said frame;
- said ratchet extending upwardly through the frame so as to contact said piston head;
- and
- c. an actuating means comprising a flexible pawl connected to said ratchet;
- a handle pivotally connected to said casing, said pivotal connection including a pin and a spring means positioned between and interconnecting said handle and said pawl so as to enable the movement of the handle to flex the flexible pawl whereby upon such flexing the pawl incrementally advances said ratchet member towards the piston head and displaces the head upwardly into the container so as to dispense a quantity of comestible corresponding to the displaced volume in said container, said frame having a latch means, said latch means comprising a pawl having a tab extending from within the casing, said pawl being attached to pegs extending from said frame, said pawl being positioned on the opposite side of the ratchet relative to said handle, said pawl having a tooth which engages said ratchet on the opposite side that the flexible pawl engages the ratchet to restrain the ratchet from movement away from the container.
