Universal toothbrush

Abstract

A universal toothbrush formed to provide overcoming drawbacks of the prior arts with elastic pump-dispenser for impeccable supplying of toothpaste on surface of the bristles with comfortable design for use and simple manufacturing. A toothbrush is formed from three separate branches; a replaceable brush, a conic annular resilient pump formed with cover for short elastic push-button, located on horizontal axis with opposite bulges in chamber, means to divide the paste in order to control the supply. The pump located in conical plastic compartment having on vertical axis an inlet valve with a ball and an outlet flap valve, which hermetical connected with resilient pump, and a replaceable/refillable cartridge for the toothpaste, made from tubing, which bypasses expensive equipment, it has inside a special piston that capture the paste and indexes. First support to slide up easily the piston behind toothpaste and second do not slide down under weight of the paste. Said design allows an impeccable supplying of the toothpaste on the surface of the bristles.

1 . An universal toothbrush has a vertical axis (opening) between an end of a brush head and end of the cartridge, and comprising three separate parts: a replaceable brush head, a conical annular pump's compartment is made as a single plastic unit with an outlet swing flap valve, located in upper neck and inlet valve with ball, located in lower end on a vertical an opposite axis of compartment, the two necks of the valves are hermetical connected with inside resilient pump-dispenser formed with outside short button on which installs plastic covering (button), located on horizontal axis with opposite bulges in oblong chamber, means for divide the toothpaste, for controlled supply owing to pressing of the push-button for creating sufficient pressure for pushing out the toothpaste toward the bristles from cartridge.
 In one embodiment of the universal toothbrush include a cover, which protects the brush head and pump's button in trip, etc. It also covered inside a cover for opening between bristles.   In retail an inlet valve with ball will has an elastic temporary stopper used to shut the valve for to divide the empty pump from cartridge with toothpaste.   The bottom part of the pump-dispenser connects with a replaceable/refillable cartridge for the toothpaste, made from tubing in which slide up a special piston that has niche and opening in plate, both captures the toothpaste for support to slide the piston behind the paste when in chamber creates vacuum after release the button.   The piston has in bottom part indexes, which does not give room to slide the piston down under, weight of the paste.   In set of the universal toothbrush could be included a brush holder for the wall that can be gathered each to other and collar for fill out the cartridge from any soft tubes with toothpaste.   
   
   
       2 . The universal toothbrush described in  claim 1  wherein said a replaceable brush head with a separate cover that close an opening between bristles and pump's button is covered by special detachable cover means for transportation, etc. 
   
   
       3 . The universal toothbrush described in  claim 1  wherein said pump has on opposite vertical axis an inlet valve with ball and an outlet swing flap valve, which could have one or few swing able flaps. 
   
   
       4 . The universal toothbrush described in  claim 1  wherein said resilient pump-dispenser formed with short button located on horizontal axis with one or two bulge located opposite in oblong chamber, means for divide the toothpaste, for controlled supply, etc. 
   
   
       5 . The universal toothbrush described in  claim 1  wherein said the resilient pump-dispenser has the short button on which installs the plastic cover (button) for easily creating of sufficient pressure, by pushing out the toothpaste toward the bristles from cartridge. 
   
   
       6 . The universal toothbrush described in  claim 1  wherein said inlet valve with ball temporary covered by stopper used to shut empty pump for to divide the cartridge with toothpaste in retail and then it take apart before using. 
   
   
       7 . The universal toothbrush described in  claim 1  wherein said pump-dispenser connects with a replaceable/refillable cartridge for the toothpaste that could make from tubing, thus bypassing expensive equipment for production, in said cartridge slide up a special piston. 
   
   
       8 . The universal toothbrush described in  claim 1  wherein said piston has niche and opening in plate, both captures the toothpaste for support to slide easily the piston behind the paste when in chamber is creates vacuum after release the button, the piston has also in the bottom end the indexes, which does not give room to slide the piston down under, weight of paste.
