       BACKGROUND 
       [0004]    (1) Field of the invention 
         [0005]    Relating to improvements in devices used for oral hygiene. 
         [0006]    Men and women have always sought to keep themselves clean in order to appear fresh and presentable to themselves and to their neighbors. They primarily do this by maintaining proper hygiene using a simple routine of daily showering using soap and shampoo as well as proper cleaning of the mouth through the use of a toothbrush. There are many forms of brushes available on the market today that are typically made to support the needs of different users; amongst these are electric brushes, brushes designed with bristles having varying surface patterns, ergonomic brushes supporting different hand postures and brushes with angled brush head. 
         [0007]    Amongst the electric type there are electric toothbrushes including those that are battery powered as well as those that are powered by a conventional wall outlet. However, a problem arises in that the brushes described previously are of no help whatsoever in the event that you can not get a tube of toothpaste. Perhaps the store has run out of a user&#39;s favorite brand of toothpaste or there simply is no brand available locally so that a user must turn to another alternative to keep his or her mouth fresh and clean. Additionally, perhaps a user does not want to purchase a new one since he or she already has a costly expensive electric one at home. Thus, there needs to be some solution that overcome the aforementioned deficiencies found above in the prior art.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0017]      FIG. 1   a  illustrates a back elevation view of an embodiment of the Disposable Toothbrush device Having an Internal Toothpaste Cartridge. The toothbrush of  FIG. 1   a  has three main components, namely, a head having a thin deformable plastic cap  115 , a support arm  105  and a handle  100 . The device of  FIG. 1   a  is made from plastics for the arm and handle, nylon for the bristles in the head. Rubber is also useable for ergonomic improvement of the handle and heated glue is used to bind the components together.  FIG. 1   b  illustrates a front elevation view of an embodiment of the Disposable Toothbrush Having an Internal Toothpaste Cartridge. This view again shows the extendible support arm  105  and the ergonomic handle  100 . Additionally, it shows the toothbrush head having three delivery ports  310  found amongst the head&#39;s bristles for the expulsion of toothpaste from the thin deformable plastic cap on the other side of the head. 
         [0018]      FIG. 2   a  illustrates a side cross-section view of an embodiment of the Disposable Toothbrush Having an Internal Toothpaste Cartridge featuring a fully extended handle and arm configuration. A plastic support arm  105  is integrated with the head and has bristles inserted therein and a thin deformable plastic cap  115  is attached to the back side of the head as discussed below. Further, a toothpaste gel  110  is placed within the thin deformable plastic cap with a dispensing device so as to prepare the thin deformable plastic cap for compression and release of the gel  110  into the delivery ports  310  shown in another figure. A rectangular oblong solid support arm  105  has an integral portion of the same formed as an plastic oblong rectangular solid  215  of greater dimensions in width and thickness than the support arm  105 . 
         [0019]    Additionally, this integral portion  215  has a rectangular locking protrusion  225  that extends outwards from the front face of the integral portion at the bottom of the integral portion  215 . This locking protrusion  225  slides under a corresponding first auxiliary locking protrusion  220  that extends outwards from the inner wall of the ergonomic handle  100 . The first auxiliary locking protrusion  220  holds the support arm  105  in place by sitting atop a ledge formed by the extended locking protrusion  225  as it flows back into the front surface of the integral portion  215  of the support arm  105 . A second auxiliary locking protrusion  230  extends at an angle from the inner surface of the ergonomic handle  100  such that it is wedged underneath the lip of the locking protrusion  225 . 
         [0020]    Finally, the ergonomic handle  100  has a hollow or cavity  235  running down the inside longitudinally so as to permit the extension of support arm  105  along with the integral portion  215 . The device is forbidden from going further by the bottom of the integral portion  215  impacting the inner walls of the hollow cavity  235  as it slopes inwards reducing the dimensions of the cavity; alternatively, the neck of the handle impacting the underside of the tooth brush head. Further, the device is forbidden from extending further by the locking protrusion  225  snapping into a space that hollows out above the second auxiliary locking protrusion  230  and beneath the first auxiliary locking protrusion  220 .  FIG. 2   b  illustrates a side cross-section view of an embodiment of the Disposable Toothbrush Having an Internal Toothpaste Cartridge featuring a extendable handle and arm configuration as discussed above. Finally, there is a transition from round shaft to square shaft shown in  210 . 
         [0021]      FIG. 3   a  illustrates an exploded front view of an embodiment of the brush head  325  including the bristles portion of the toothbrush having delivery ports  310  for expulsion of the toothpaste material; these delivery ports are shown more clearly with regards to  FIGS. 3   b - 3   c.    FIG. 3   b  illustrates an exploded side view cross section of an embodiment of the bristles portion and the thin deformable plastic cap-paste portion of the toothbrush having delivery ports for expulsion of the toothpaste material with the thin deformable plastic cap not connected to the brush head. A thin deformable plastic cap  110  is to be pressed into the head of the toothbrush having a concavity shown in  FIG. 3   a  that allows for more paste; this thin deformable plastic cap  110  covers the toothpaste gel  315 .  FIG. 3   c  illustrates an assembled side view cross section of an embodiment of the bristles portion, the thin deformable plastic cap-paste portion of the toothbrush having delivery ports for expulsion of the toothpaste material with the thin deformable plastic cap connected to the back of the brush head. 
         [0022]    The thin deformable plastic cap  110  is connected to the head  325  of the toothbrush through a downwards lip  320  running along the perimeter of the brush head at its bottom edge; this thin deformable plastic cap is connected to the back of the brush head through the use of an adhesive or by being heat treated with a heating element during manufacturing; this fuses the head and thin deformable plastic cap together thereby making a completed device. When a user wishes to expel toothpaste gel through delivery ports  310  all he or she has to do is press down on the back of the thin deformable plastic cap  110  compressing it until the gel is expelled through delivery ports  310  into the bristles. These three circular delivery ports  310  perforate the head  325  of the toothbrush from one side until the other side of the head  325 . 
         [0023]      FIG. 4   a  illustrates a side view of a hollow handle  100  of an embodiment.  FIG. 4   b  illustrates a side section view of a thin deformable plastic cap  110  of an embodiment.  FIG. 4   c  illustrates a section side view of a toothpaste portion  315  of an embodiment.  FIG. 4   d  illustrates a support arm  105  and associated brush bristle head.  FIG. 4   e  illustrates a section side view section of a completed device having the support arm  105 , associated brush bristle head  325 , thin deformable plastic cap and gel in an embodiment where the support arm is inserted as far as possible  400  into the handle.  FIG. 4   f  illustrates a section side view of a completed device having the support arm  105  associated brush bristle head  325 , thin deformable plastic cap and gel in an embodiment where the support arm is fully extended. 
         [0024]      FIG. 5   a  illustrates a working side view of a user opening the toothbrush of an embodiment. A user grasps ahold of the handle with one hand and with the head with another hand. Using both hand the user pulls  500  the head and support arm from its initial position until it opens completely. Then as shown in  FIG. 5   b - 5   c,  the user compresses  505  the toothpaste  315  so as to make the substance flow through the delivery ports in the head of the brush down into the bristles  510  of the brush head so as to be made useable for brushing the teeth of the user. 
         [0025]      FIG. 6   a  illustrates an initial position for a support arm in a side view for a Disposable Toothbrush Having an Internal Toothpaste Cartridge  600  and  FIG. 6   b  illustrates the packaging  605  used by the device. 
         [0026]    The invention has thus been described in such clear and precise terms as to enable one of ordinary skill in the art to understand its fundamental principles.
