- said housing has a longitudinal axis; and
- each of said slots includes a first portion extending from the outer edge of said housing generally parallel to the longitudinal axis of said housing, a second portion connected to said first portion and extending generally perpendicularly thereto and a third portion connected to said second portion and extending generally perpendicularly thereto and generally parallel to the longitudinal axis of said housing in a direction toward the outer edge of said housing.
- 4. A cup dispenser according to claim 3 wherein
- said lugs have a length and width, said first and second slot portions have a width and said third slot portion has a width and height; and
- the width of said lugs is less than the width of said first and third slot portions, the height of said lugs is greater than the width of said second slot portion and the height of said third slot portion is greater than the width of said second slot portion.
- 5. A cup dispenser according to claim 4 wherein
- said housing has tab-like portions defined by the outer edge of said housing and said first, second and third slot portions, said tab-like portions being flexed from a normal position in a direction toward the outer edge of said housing to a flexed position in response to movement of said lug through said second slot portion during relative movement of said collar and said housing from the unlocked position toward the locked position and returning to its normal position when said lug reaches said third slot portion; and
- said collar includes a circumferentially extending ledge projecting radially inwardly from the inner surface of said collar in the vicinity of each of said slots, said ledge extending over the outer edge of said housing and having a recess in the vicinity of each of said tab-like portions for accommodating movement of said tab-like portions to the flexed position.
- 6. A cup dispenser according to claim 1 wherein
- said housing normally has a circular cross section; and
- said collar includes a plurality of circumferentially spaced guide means for engaging the discharge end of said housing, when the cross section of the discharge end of said housing has an out of round shape, and moving the discharge end of said housing back to its normal round shape during assembly of said collar and said housing.
- 7. A cup dispenser according to claim 6 wherein
- the discharge end of said housing has an inner wall; and
- each of said guide means includes a generally L-shaped guide member having a first leg extending radially inwardly from the inner surface of said collar and a second leg depending from said first leg and having a tapered guide surface which engages the inner wall of said housing and cams the discharge end of said housing radially outwardly toward said collar.
- 8. A cup dispenser according to claim 7 including a pair of said guide members circumferentially spaced and located on opposite sides of each of said lugs.
- 9. A cup dispenser comprising
- an elongated tubular housing for storing a plurality of cups nested in a stack and having an exterior surface, an interior and a discharge end through which cups are dispensed and including an outer edge;
- an annular collar surrounding the exterior surface of said housing and having an inner surface;
- locking means on said collar and said housing cooperating to provide a removable connection between said collar and said housing at a location adjacent the discharge end of said housing and further cooperating to afford relative movement of said collar and said housing between a locked position wherein relative longitudinal and rotational movement of said collar and said housing are restrained and an unlocked position wherein relative movement of said collar and said housing is permitted to separate one from the other, said locking means comprising a plurality of circumferentially spaced lugs extending radially inwardly from the inner surface of said collar, and a plurality of circumferentially spaced generally J-shaped slots in said housing and extending from the outer edge of said housing for receiving said lugs, portions of the inner surface of said collar and said locking means exposed to the interior surface of said housing in the vicinity of the discharge end, said collar and said locking means being connected together to eliminate the presence of crevices or cavities which can trap bacteria; and
- an annular retaining ring carrying a cup holding member and removably mounted on said collar whereby said cup holding member is disposed over the discharge end of said housing to control removal of cups from the stack.
- 10. A cup dispenser according to claim 9 wherein
- said housing has a longitudinal axis;
- each of said slots includes a first portion extending from the outer edge of said housing generally parallel to the longitudinal axis of said housing, a second portion connected to said first portion and extending generally perpendicularly thereto and a third portion connected to said second portion and extending generally perpendicularly thereto and generally parallel to the longitudinal axis of said housing in a direction toward the outer edge of said housing; and
- said lugs have a length and width, said first and second slot portions have a width and said third slot portion has a width and height; and
- the width of said lugs is less than the width of said first and third slot portions, the height of said lugs is greater than the width of said second slot portion and the height of said third slot portion is greater than the width of said second slot portion.
- 11. A cup dispenser according to claim 10 wherein
- said housing has tab-like portions defined by outer edge of said housing, said first, second and third slot portions, said tab portions being flexed from a normal position in a direction toward the outer edge of said housing to a flexed position in response to movement of said lug through said second slot portion during relative movement of said collar and said housing from the unlocked position toward the locked position and returning to its normal position when said lug reaches said third slot portion; and
- said collar includes a circumferentially extending ledge projecting radially inwardly from the inner surface of said collar in the vicinity of each of said slots, said ledge extending over the outer edge of said housing and having a recess in the vicinity of each of said tab portions for accommodating movement of said tab portions to the flexed position.
- 12. A cup dispenser according to claim 11 wherein
- said housing normally has a circular cross section; and
- said collar includes a plurality of circumferentially spaced guide means for engaging the discharge end of said housing, when the cross section of the discharge end of said housing has an out of round shape, and moving the discharge end of said housing back to its normal round shape during assembly of said collar and said housing.
- 13. A cup dispenser according to claim 12 wherein
- the discharge end of said housing has an inner wall; and
- each of said guide means includes a generally L-shaped guide member having a first leg extending radially inwardly from the inner surface of said collar and a second leg depending from said first leg and having a tapered guide surface which engages the inner wall of said housing and cams the discharge end of said housing radially outwardly toward said collar.
