Abstract

Dispenser includes housing for at least two rolls of tissue paper, access opening in housing, and closure selectively closing a portion of access opening. Closure includes body, first wall movably connected to body at first edge of first wall; and second wall movably connected to body at first edge of second wall. First and second wall are urged toward each other to respectively position second edges of first and second walls opposite to first edges in a blocking position in which sliding of closure into first or second position is blocked until a predetermined amount of paper of second or first roll, respectively, has been dispensed. Closure includes first and second spring urging first and second walls, respectively, toward each other, spring force of first and second springs being configured to automatically return closure into first or second position, respectively, when sliding of the closure into first or second position, respectively, is blocked.

First claim

The invention claimed is:

1. A dispenser for rolls of tissue paper, comprising:
a housing for accommodating at least two of said rolls;
an access opening defined in said housing for allowing access to the rolls; and
a closure for selectively closing a portion of the access opening, the closure being slideably mounted to the housing between a first position closing a first portion of the access opening preventing access to a first roll of said rolls and a second position closing a second portion of the access opening preventing access to a second roll of said rolls,
wherein the closure comprises:
a body;
a first wall having opposed first and second edges and being movably connected to the body at the first edge of the first wall;
a second wall having opposed first and second edges and being movably connected to the body at the first edge of the second wall;
a first spring urging the first wall toward the second wall; and
a second spring urging the second wall toward the first wall,

wherein the first and second wall are urged toward each other to respectively position the second edges of the first and second walls in a blocking position in which sliding of the closure into the second position is blocked until a predetermined amount of paper of the second roll has been dispensed and in which sliding of the closure into the first position is blocked until a predetermined amount of paper of the first roll has been dispensed,
wherein spring force of the first and second springs is configured to automatically return the closure into the first position when sliding of the closure into the second position is blocked and to automatically return the closure into the second position when sliding of the closure into the first position is blocked.

2. The dispenser according to claim 1 , wherein the first and second wall each comprises a bump adjacent to the second edge, the bump of the first wall protruding toward the second wall and the bump of the second wall protruding toward the first wall.

3. The dispenser according to claim 2 , wherein the first and second walls have a concave portion from the first edges toward the second edges and a convex portion adjacent the second edges, respectively, wherein inner surfaces of the bumps facing each other are continuous with the concave portions, respectively.

4. The dispenser according to claim 1 , wherein a first end of the first spring is connected to the first wall between the first and second edges of the first wall and a second end of the first spring is connected to the body, and
wherein a first end of the second spring is connected to the second wall between the first and second edges of the second wall and a second end of the second spring is connected to the body.

5. Dispenser according to claim 4 , wherein each wall comprises a support protrusion supporting the second ends of the first and second springs, the support protrusions protruding away from the first and second walls in a direction along an axis of rotation of the first and second walls, the support protrusions operating as a stop respectively limiting the rotational movement of the first and second walls toward each other.

6. The dispenser according to claim 4 , wherein the first and second springs extend in the blocking position of the first and second walls along the sliding direction of the closure.

7. The dispenser according to claim 1 , wherein the body comprises a gradually increasing rib extending along preferably the axis of rotation of the first and second walls.

8. The dispenser according to claim 7 , wherein the rib connects at its highest position to a back wall of the body.

9. The dispenser according to claim 7 , wherein the rib is located at a center between the axis of rotation of the first and second walls on the body.
