Toothbrush assembly

Abstract

A toothbrush assembly comprising a head component, a handle component detachably attached to the head component, and a toothpaste cartridge removably received within the handle component. The head component comprises a first body member having a first cavity and a plurality of holes configured on a front end portion, and a plurality of bristles configured on the front end portion of the first body member. The handle component comprises a second body member having a second cavity, a rotatable member coupled to a distal end portion of the second body member, and a first turning lug coupled to the rotatable member. The toothpaste cartridge comprises an enclosure member for storing toothpaste therein, a rod positioned within the enclosure member, a second turning lug coupled to the rod, and a plunger member movably mounted on the rod.

1 . A toothbrush assembly comprising:
 a head component comprising
 a first body member having a first cavity extending within the first body member from a rear end portion of the first body member, and a plurality of holes configured on a front end portion of the first body member, the plurality of holes fluidically coupled to the first cavity, wherein the first cavity includes a first diameter at the rear end portion and a second diameter at the front end portion, where the first diameter is greater than the second diameter and a segment of decreasing diameter where said segment of decreasing diameter starts at the first diameter and decreases to the second diameter, and 
 a plurality of bristles configured on the front end portion of the first body, the plurality of bristles surrounding the plurality of holes; 
   a handle component detachably attached to the head component, the handle component comprising
 a second body member having a second cavity extending within the second body member from a proximal end portion to a distal end portion of the second body member, 
 a rotatable member coupled to the distal end portion of the second body member, and 
 a first turning lug coupled to the rotatable member in a manner such that the first turning lug is disposed within the second cavity of the second body member; and 
   a toothpaste cartridge removably received within the handle component, the toothpaste cartridge comprising
 an enclosure member capable of being received within the second cavity of the second body member, the enclosure member storing toothpaste therein, 
 a rod member positioned longitudinally within the enclosure member, 
 a second turning lug coupled to an end portion of the rod member and disposed outside the enclosure member, the second turning lug operatively coupled to the first turning lug, and 
 a plunger member movably mounted on the rod member, 
   wherein the plunger member is adapted to move along the rod member upon rotating the rotatable member for dispensing the toothpaste from the enclosure member to the first cavity of the first body member, thereby receiving the dispensed toothpaste by the plurality of bristles through the plurality of holes.   
   
   
       2 . The toothbrush assembly of  claim 1 , further comprising a cap member adapted to be removably coupled to the first body member of the head component for enclosing the plurality of bristles within the cap member. 
   
   
       3 . The toothbrush assembly of  claim 2 , wherein the cap member is removably coupled to the head component by a snap-fit coupling. 
   
   
       4 . The toothbrush assembly of  claim 3 , wherein the cap member comprises a protruded portion, and the rear end portion of the first body member of the head component comprises a groove portion capable of receiving the protruded portion of the cap member for enabling the snap-fit coupling between the cap member and the first body member of the head component. 
   
   
       5 . The toothbrush assembly of  claim 2 , wherein the cap member comprises a plurality of vents configured thereon. 
   
   
       6 . The toothbrush assembly of  claim 1 , wherein the detachable attachment between the head component and the handle component is enabled by a threadable coupling. 
   
   
       7 . The toothbrush assembly of  claim 6 , wherein the first body member of the head component comprises internal threads configured on the rear end portion of the first body member, and the second body member of the handle component comprises external threads configured on the proximal end portion of the second body member, the external threads coupled to the internal threads for enabling the threadable coupling between the head component and the handle component. 
   
   
       8 . The toothbrush assembly of  claim 6 , further comprising an O-ring adapted to be positioned between the head component and the handle component for strengthening the threadable coupling therebetween and the seal created thereby. 
   
   
       9 . The toothbrush assembly of  claim 1 , wherein the enclosure member comprises a rim portion configured on an edge of the enclosure member. 
   
   
       10 . The toothbrush assembly of  claim 9 , wherein the toothpaste cartridge further comprises a peel-off cover adapted to be disposed on the rim portion of the enclosure member for enclosing the toothpaste stored within the enclosure member. 
   
   
       11 . The toothbrush assembly of  claim 1 , wherein the plunger member is movably mounted on the rod member by a threadable arrangement. 
   
   
       12 . The toothbrush assembly of  claim 1 , wherein, upon depletion of the toothpaste contained therein, said cartridge may be replaced with another cartridge that contains toothpaste.
