Abstract
A dispenser for semiliquid materials. The dispenser includes a cylindrical housing which is wall-mountable and which has an upper, closed end and a downwardly opening open end. The housing has a column coaxial within the housing attached to the closed end. The column serves as a fixed piston in cooperation with a cup which is threadedly engaged with the housing to telescopically sheath the piston. Rotation of the cup telescopically moves the cup over the piston thereby displacing the material in the cup through a spout in the base of the cup. The material may be either encapsulated and the capsule placed in the cup or the cup may serve as a container for a bulk quantity of material.
Claims6
A wall-mountable dispenser for encapsulated semiliquid materials comprising:
- a cylindrical housing having an open end and a closed end, the internal wall of the housing being threaded;
- means for removably mounting the housing on a vertical surface with the housing in a generally vertical orientation having the open end of the housing downward;
- a raised ridge circumscribing the housing adjacent the closed end;
- a removable fixture for placement on the housing in abutment with the raised ridge comprising (a) a semicylindrical wall having an inside diameter dimensionally corresponding to the outside diameter of the housing and a height greater than the distance between the raised ridge and the closed end of the housing so as to form a basin at the closed end of the housing and (b) a shelf extending outwardly from the wall and having article-receiving apertures therein;
- a coaxial piston fixed to the closed end of the housing and spaced from the housing wall, the piston having side walls parallel with the walls of the housing and extending an incremental distance from the open end of the housing;
- a cup configurated to telescopically cooperate between the housing and the piston, the cup having thread engaging means for engaging the threaded wall of the housing, the cup having a polygonal spout receiving hole in the bottom of the cup;
- a cylindrical capsule for semiliquid materials and having a spout at one end and a cap for the spout, the spout having a polygonal base dimensionally corresponding to the polygonal hole, the capsule being dimensionally configurated to be received in the cup with the spout extending through the hole in the cup and the polygonal base preventing rotation of the capsule in the cup when the cap for the capsule spout is removed and replaced;
- and
- means for moving the cup relative to the piston to squeeze the capsule between the cup and the piston to force the semiliquid materials through the spout, said means comprising a hand gripping portion around the base of the cup to accommodate hand rotation of the cup to cause a corresponding axial movement of the cup into the housing.

A dispenser for encapsulated semiliquid materials comprising:
- a cylindrical housing having an open end and a closed end, the internal walls of the housing being threaded;
- means for removably mounting the housing on a vertical surface with the housing in a generally vertical orientation comprising at least one suction cup attached to the housing by a bracket;
- a raised ridge circumscribing the housing adjacent the closed end of the housing;
- a semicircular shelf removably attached to the housing, the shelf extending perpendicular to the axis of the housing and being adapted to be placed in abutment with the raised ridge;
- a piston coaxial with the housing, the piston being fixed to the closed end of the housing and spaced from the housing wall, the piston extending an incremental distance beyond the confines of the housing;
- a cup adapted to be telescopically received between the housing and the piston, the cup having a polygonal spout receiving hole in the bottom and thread engaging means around the lip of the cup to threadedly engage the threads of the housing;
- means for forming a seal between the piston and the cup to inhibit materials in the cup from being forced from the cup between the cup and the piston;
- structure selectively insertable into the cup to selectively adapt the cup to bulk and encapsulated materials comprising a separate spout embodiment operable to fit in the bottom of the cup to adapt the cup to bulk, semiliquid materials and interchangeable with a cylindrical capsule for semiliquid materials configurated to be received in the cup and be compressed between the cup and the piston, the capsule having a spout oriented to extend through the hole in the cup;
- and
- finger engaging means on the cup for hand rotation of the cup thread engaging means in mating relationship with the housing threads to accommodate axial movement of the cup against the piston to compress the capsule and force material therefrom.
