A shut-off system for a dispenser includes a pinch member that moves relative to a guide and which is normally biased against a flexible outlet tube that is disposed therebetween. The flexible outlet tube that carries material, such as soap, supplied from a pump to an outlet nozzle. The pump and the pinch member are in operative engagement with an actuator, such that when the actuator is not engaged, the pinch member closes the outlet tube to prevent residual material retained in the outlet tube from flowing or drooling out of the outlet nozzle. Correspondingly, when the actuator is engaged, the pump is compressed, and the pinch member is moved away from the outlet tube, allowing the material to be pumped through the outlet tube and dispensed from the outlet nozzle.

1. A dispenser to dispense material comprising: a pump having an inlet adapted to receive material, and an outlet;an outlet tube in fluid communication with the outlet, the outlet tube extending in a first direction and having an outlet nozzle; anda clip comprising: a base member;a cap member having a top surface extending in the first direction and lying within a plane, wherein at least one of: the base member is movable relative to the cap member between an opened position and a closed position, orthe cap member is movable relative to the base member between the opened position and the closed position; anda sealing arm extending from the cap member, a first portion of the sealing member lying on a first side of the plane, and a second portion of the sealing member lying on a second side of the plane, wherein: in the closed position the clip is disposed relative to the outlet tube such that the sealing arm applies a first force to the outlet tube in a direction from the cap member toward the base member, the first force sufficient to compress the outlet tube; andin the opened position the clip is disposed relative to the outlet tube such that the sealing arm does not apply a force to the outlet tube sufficient to compress the outlet tube;wherein when the pump is compressed, the material is urged through the outlet tube in a direction from the outlet toward the outlet nozzle at a second force sufficient to overcome the first force to allow the material to be dispensed through the outlet nozzle. 2. The dispenser of claim 1, wherein the cap member is pivotably joined to the base member. 3. The dispenser of claim 1, wherein the base member includes a lock aperture, and the cap member includes a tab to be received within the lock aperture to retain the cap member to the base member. 4. The dispenser of claim 1, wherein the clip is removable from the outlet tube. 5. The dispenser of claim 1, wherein the clip is integral with the outlet tube. 6. The dispenser of claim 1, wherein the outlet tube includes at least one retention tab in operative engagement with the clip to prevent the clip from sliding along the outlet tube. 7. The dispenser of claim 1, wherein the base member and the cap member are attached to one another by a living hinge. 8. A dispenser to dispense material comprising: a pump having an inlet adapted to receive material, and an outlet;an outlet tube in fluid communication with the outlet, the outlet tube having an outlet nozzle; anda clip comprising: a base member; anda cap member comprising: an upper edge wall;a lower edge wall spaced apart from the upper edge wall;a first lateral edge wall attached to the upper edge wall and the lower edge wall; anda second lateral edge wall attached to the upper edge wall and the lower edge wall, the second lateral edge wall spaced apart from the first lateral edge wall, the lower edge wall extending between the first lateral edge wall and the second lateral edge wall, wherein at least one of:the base member is movable relative to the cap member between an opened position and a closed position, orthe cap member is movable relative to the base member between the opened position and the closed position, wherein: in the closed position the clip is disposed relative to the outlet tube such that a first force is applied to the outlet tube in a direction from the cap member toward the base member, the first force sufficient to compress the outlet tube; andin the opened position the clip is disposed relative to the outlet tube such that the clip does not apply a force to the outlet tube sufficient to compress the outlet tube;wherein when the pump is compressed, the material is urged through the outlet tube in a direction from the outlet toward the outlet nozzle at a second force sufficient to overcome the first force to allow the material to be dispensed through the outlet nozzle. 9. The dispenser of claim 8, wherein the base member and the cap member are attached to one another by a living hinge. 10. The dispenser of claim 8, wherein the lower edge wall extends continuously between the first lateral edge wall and the second lateral edge wall. 11. The dispenser of claim 10, wherein the upper edge wall, the lower edge wall, the first lateral edge wall, and the second lateral edge wall define an aperture extending through the cap member. 12. The dispenser of claim 11, wherein the clip comprises a sealing arm attached to the upper edge wall and extending into the aperture, the sealing arm surrounded by the upper edge wall, the lower edge wall, the first lateral edge wall, and the second lateral edge wall and configured to apply the first force to the outlet tube. 13. The dispenser of claim 8, wherein the outlet tube comprises a first retention tab and a second retention tab projecting outwardly from an outer surface of the outlet tube, the first retention tab spaced apart from the second retention tab to define a space. 14. The dispenser of claim 8, wherein, in the closed position, the base member extends parallel to the cap member. 15. A dispenser to dispense material comprising: a pump having an inlet adapted to receive material, and an outlet;an outlet tube in fluid communication with the outlet, the outlet tube having an outlet nozzle, the outlet tube comprising a first retention tab and a second retention tab projecting outwardly from an outer surface of the outlet tube, the first retention tab spaced apart from the second retention tab to define a space; anda clip comprising: a base member comprising: a first wall; anda second wall spaced apart from the first wall to define a retaining channel configured to receive the outlet tube;a cap member attached to the base member, the cap member comprising: an upper edge wall;a lower edge wall spaced apart from the upper edge wall;a first lateral edge wall attached to the upper edge wall and the lower edge wall; anda second lateral edge wall attached to the upper edge wall and the lower edge wall, the second lateral edge wall spaced apart from the first lateral edge wall; anda sealing arm attached to the upper edge wall;wherein when the outlet tube is received within the retaining channel between the first wall and the second wall and the cap member is attached to the base member a first force is applied to the outlet tube by the sealing arm in a direction from the cap member toward the base member, the first force sufficient to compress the outlet tube, and wherein the cap member is received within the space between the first retention tab and the second retention tab such that the first retention tab and the second retention tab limit movement of the clip relative to the outlet tube, the first retention tab adjacent to the upper edge wall and the second retention tab adjacent to the lower edge wall, the lower edge wall disposed between the sealing arm and the second retention tab;wherein when the pump is compressed, the material is urged through the outlet tube in a direction from the outlet toward the outlet nozzle at a second force sufficient to overcome the first force to allow the material to be dispensed through the outlet nozzle. 16. The dispenser of claim 15, wherein the lower edge wall extends between the first lateral edge wall and the second lateral edge wall. 17. The dispenser of claim 16, wherein the upper edge wall, the lower edge wall, the first lateral edge wall, and the second lateral edge wall define an aperture extending through the cap member. 18.
