A device for dispensing a stick-formed spreadable food comprising:
- a housing defining a chamber for holding the food, the housing having four substantially flat walls, each wall having inner and outer surfaces and upper and lower ends;
- an inlet defined by the upper ends of the walls;
- at least one inwardly and downwardly extending tongue formed at the lower end of one of said walls;
- and
- an outlet defined in part by a lower end of said at least one tongue;
- and
- a piston, slidable in one direction from the inlet to the outlet within the housing and having a lower face engageable with an upper end of the food for moving the food through the housing so that the food protrudes beyond the at least one tongue, wherein the housing further comprises a plurality of detents engageable by the piston for retaining the piston against motion in a direction opposite to the one direction and retaining the piston in a plurality of positions within the housing, the piston being slidable through the housing so that the piston is removable through the outlet.

A dispenser for spreadable, stick-shaped food in combination with the spreadable, stick-shaped food, the combination comprising:
- a stick-shaped spreadable food;
- a hollow housing having first and second ends, the food being disposed in the housing, the first end having an opening for receiving the food and the second end comprising means for resiliently engaging the food, proximate one end of the food, to hold the food within the dispenser;
- a piston for exerting force on the other end of the food for pushing the food through the dispenser, so that the one end of the food extends from the dispenser for application as desired;
- and
- wherein the housing further comprises detents and the piston further comprises means for engaging the detents, and the piston is slidable through the housing from the first end to the second end so that the piston is removable through the second end of the housing, wherein the detents and means for engaging prevent motion of the piston in a direction from the second end to the first end.
