Patent ID: 8365416

Claim:
A hand held device comprising: a. a handle comprising i. a proximal end forming a product dispensing aperture; ii. a distal end, opposite said proximal end, said distal end forming a cavity for housing a fluid disposed within said handle, wherein said product dispensing aperture and said cavity are in fluid communication via a supply channel; iii. a peristaltic pump disposed on said handle between said proximal end and said distal end, said peristaltic pump comprising a rotating actuator physically engaged with said supply channel, wherein rotation of rotating actuator directs said fluid from the vicinity of the cavity to said product dispensing aperture via said supply channel; iv. a flexible barrier positioned between said rotating actuator and said supply channel, and v. wherein said flexible barrier comprises a rotating actuator contacting surface and a supply channel contacting surface, and wherein the flexible barrier comprises more than one layer, wherein the layer forming the rotating actuator contacting surface has a lower coefficient of friction than the layer forming the supply channel contacting surface; and b. a device head, operably connected to said proximal end.
