Abstract

An oral care system includes a dispenser comprising a product tube having a reservoir containing an oral care material and an outlet. In one embodiment, the dispenser may be configured for detachable coupling to a toothbrush. A compression device engages the product tube and pressurizes the tube contents. The oral care material may be dispensed by actuating a valve fluidly coupled to the reservoir and outlet. In one embodiment, actuating the valve includes a flow orifice movable into and out of a flow path through the dispenser. Oral care material may be dispensed by positioning the orifice in the flow path in which the pressurized material flows outwards the product tube. To stop the flow of oral care material, the orifice is removed from the flow path which blocks the path. An operating button is provided in one embodiment to change position of the flow orifice.

First claim

What is claimed is:

1. A dispenser comprising:
a housing defining a longitudinal axis;
a pressurized product tube disposed in the housing and including a reservoir containing a material;
an outlet in fluid communication with the reservoir;
a valve fluidly coupled to the outlet, the valve being movable between an open dispensing position and a closed non-dispensing position; and
a compression device disposed inside the housing of the dispenser, the compression device configured to apply pressure to the product tube for dispensing the material, wherein the compression device includes a pair of opposing pressure plates resiliently biased into engagement with opposing sides of the product tube, the plates operable to squeeze the material from the reservoir when the valve is in the open dispensing position;
wherein the valve is configured to dispense the material from the reservoir under pressure when in the dispensing position;
wherein the valve includes an orifice movable into and out of a flow path defined through the outlet; and
wherein the pressure plates are resiliently coupled together by a pair of elastomeric members each anchored to mating opposing longitudinal edges of the pressure plates along opposing lateral sides of the compression device.

2. The dispenser according to claim 1 , wherein the valve is biased towards the closed position.

3. The dispenser according to claim 1 , wherein:
when the valve is in the open dispensing position, the orifice is positioned in the flow path; and
when the valve is in the closed non-dispensing position, the orifice is positioned outside the flow path.

4. The dispenser according to claim 1 , further comprising an applicator mounted on a distal end of the dispenser in fluid communication with the reservoir.

5. The dispenser according to claim 4 , wherein the product tube includes a nozzle fluidly coupled to the applicator, the nozzle being inserted in a rearwardly open socket formed in the applicator.

6. The dispenser according to claim 1 , wherein each pressure plate is axially elongated and encloses a majority of a length of the product tube.

7. The dispenser according to claim 1 , wherein the pressure plates are transversely movable together and apart in relation to each other from a closed position to an open position, the pressure plates being biased towards the closed position by the elastomeric members.

8. The dispenser according to claim 1 , wherein the elastomeric members are formed of thermoplastic elastomers.

9. The dispenser according to claim 1 , wherein the housing is configured for insertion into a handle of a toothbrush.

10. The dispenser according to claim 1 wherein the valve is configured to dispense the material from the reservoir under constant pressure when in the dispensing position irrespective of an amount of the material contained in the reservoir.

11. An oral care system comprising:
a toothbrush including a head, and a handle coupled to the head and having an internal cavity;
a dispenser detachably mounted in the internal cavity of the handle;
the dispenser including:
a housing defining a longitudinal axis;
a pressurized tube disposed in the housing and including a reservoir containing an oral care material;
an outlet in fluid communication with the reservoir;
a valve fluidly coupled to the outlet, the valve being movable between an open dispensing position and a closed non-dispensing position; and
a compression device disposed inside the housing of the dispenser, the compression device configured to apply pressure to the product tube for dispensing the material, wherein the compression device includes a pair of opposing pressure plates resiliently biased into engagement with opposing sides of the product tube, the plates operable to squeeze the material from the reservoir when the valve is in the open dispensing position;
wherein the valve is configured to dispense oral care material from the reservoir under pressure when in the dispensing position;
wherein the valve includes an orifice movable into and out of a flow path defined through the outlet; and
wherein the pressure plates are resiliently coupled together by a pair of elastomeric members each anchored to mating opposing longitudinal edges of the pressure plates along opposing lateral sides of the compression device.

12. The oral care system according to claim 11 , wherein:
when the valve is in the open dispensing position, the orifice is positioned in the flow path; and
when the valve is in the closed non-dispensing position, the orifice is positioned outside the flow path.

13. A method for dispensing a material, the method comprising:
providing a dispenser including a housing defining a longitudinal axis, a pressurized product tube disposed in the housing and including a reservoir containing a material, and an outlet in fluid communication with the reservoir and defining a flow path for dispensing the material;
engaging opposite sides of the product tube with a compression device operably exerting an inward directed force on the reservoir;
actuating a valve fluidly coupled to the outlet of the dispenser and including a flow orifice, the orifice movable into and out of the flow path;
positioning the orifice into the flow path; and
dispensing the material from the dispenser.
