Abstract

A hair removal device is provided, comprising a handle and a collapsible reservoir suitable for containing a fluid to be dispensed during use of the hair removal device, the hair removal device additionally comprising a container enclosing the collapsible reservoir, a fluid outlet adapted to allow fluid to exit both the collapsible reservoir and the container, an orifice adapted to allow air to flow in or out of the container, and a suction device, adapted to suck fluid out of the collapsible reservoir through fluid outlet, wherein the fluid outlet comprises an applicator. The container can be rigid, deformably rigid, or a combination of both.

First claim

What is claimed is:

1. A hair removal device comprising a handle and a collapsible reservoir suitable for containing a fluid to be dispensed during use of the hair removal device, the hair removal device additionally comprising a container enclosing the collapsible reservoir, a fluid outlet adapted to allow fluid to exit both the collapsible reservoir and the container, an orifice adapted to allow air to flow in or out of the container, and a suction device, said hair removal device further comprising a razor cartridge head, said suction device comprising a chamber, said chamber comprising a chamber outlet comprising a first one way valve in fluid communication with said fluid outlet, a chamber inlet comprising a second one way valve in fluid combination with said collapsible reservoir, wherein a pressure applied to said chamber causes said first one way valve to open to allow fluid to dispense from said chamber to said razor cartridge head, while closing said second one way valve, wherein when said pressure is removed, said second one way valve opens to allow fluid to enter said chamber from said collapsible reservoir.

2. The hair removal device of claim 1 , wherein the handle comprises the container.

3. The hair removal device of claim 1 , wherein the razor cartridge head comprises one or more razor blades.

4. The hair removal device of claim 3 , wherein the suction device is a pump, and the razor cartridge head is reciprocally received on the handle, such that applying a depression force to depress the razor cartridge head from its rest state actuates the pump and dispenses fluid onto the skin of a user.

5. The hair removal device of claim 1 , wherein the suction device comprises an airless pump which is manually powered.

6. The hair removal device of claim 1 , wherein the handle is detachable.

7. The hair removal device of claim 1 , containing a shaving preparation.

8. The hair removal device of claim 1 , wherein the fluid is a depilatory.

9. The hair removal device of claim 1 , wherein the handle is deformably rigid.

10. The hair removal device of claim 1 , wherein the handle is rigid.

11. The hair removal device of claim 1 , wherein said pressure is a depression force created by a manually actuable button on said handle.
