Description:
TITLE OF THE INVENTION

TOOTH BRUSH ASSEMBLY

FIELD OF THE INVENTION

[0001] The present invention relates generally to the field of toothbrush devices and more specifically relates to a tooth brush assembly comprising a reservoir disposed within the handle of the toothbrush structured and arranged for retaining up to a 3-month supply of toothpaste therein having a sliding actuator in mechanical communication with a plunger which enables a user to push a desired amount of toothpaste through a plurality of apertures disposed around the bristles of the toothbrush head.

BACKGROUND OF THE INVENTION:

[0002] A toothbrush is an oral hygiene instrument used to clean the teeth, gums, and tongue. It consists of a head of tightly clustered bristles mounted upon a handle which facilitates the cleaning of hard to reach areas of the mouth. Toothbrushes are available with different bristle textures, sizes, and forms. Most dentists recommend using a soft toothbrush since hard bristled toothbrushes can damage tooth enamel and irritate the gums.

[0003] Toothpaste is a past or gel dentifrice used with a toothbrush as an accessory to clean and maintain the aesthetics and health of teeth.

Toothpaste is used to promote oral hygiene: it serves as an abrasive that aids in removing dental plaque and food from the teeth, assists in suppressing halitosis, and delivers active ingredients (mostly common fluoride) to help prevent tooth decay (dental carries) and gum disease (gingivitis). Salt and sodium bicarbonate (baking soda) are among materials that can be

substituted for commercial toothpaste. Toothpaste is not intended to be swallowed due to the fluoride content, but is generally not very harmful if accidentally swallowed in small amounts; however, one should seek medical attention after swallowing abnormally large amounts.

[0004] Currently there are a number of solutions for a toothpaste dispensing toothbrush. Some of these solutions attempt to combine the two products into one, but these solutions fail to meet the needs of the industry because in one example, it is inefficient to unscrew the toothbrush head to dispense toothpaste onto the toothbrush and then screw the toothbrush head back onto the device to clean one’s teeth. Other solutions attempt to dispense toothpaste through the bristles of the toothbrush, but these solutions are similarly unable to meet the needs of the industry because there is no level of control present to prevent an excess of toothpaste from being dispensed. Still other solutions seek to contain a replaceable toothpaste dispensing canister that is inserted into the bottom of the toothbrush, but these solutions also fail to meet industry needs because of the expense and need for replacing the toothpaste canister.

[0005] Ideally, a tooth brush assembly should be user-friendly and safe in use, and yet would operate reliably and be manufactured at a modest expense. Thus, a need exists for a tooth brush assembly comprising a reservoir disposed within the handle of the toothbrush, and structured and arranged for retaining up to a 3-month supply of toothpaste therein having a sliding actuator in mechanical communication with a plunger which enables a user to push a desired amount of toothpaste through a plurality of apertures disposed around the bristles of the toothbrush head so as to avoid the above- mentioned problems.

SUMMARY OF THE INVENTION

[0006] In view of the foregoing disadvantages inherent in the known toothbrush device art, the present invention provides a novel tooth brush assembly. The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a tooth brush assembly comprising a reservoir disposed within the handle of the toothbrush, and structured and arranged for retaining up to a 3-month supply of toothpaste therein, and having a sliding actuator in mechanical communication with a plunger so as to enable a user to push a desired amount of toothpaste through a plurality of apertures disposed around the bristles of the toothbrush head.

[0007] A tooth brush assembly comprising: an elongated main body; a toothpaste container; a slider member; and a brush head. The elongated main body includes: a proximal end; a distal end having an aperture therethrough, and a slot therethrough; and a hollow interior volume. Wherein said hollow interior volume extends between said proximal end and said distal end.

[0008] The toothpaste container includes a proximal end; a distal end having an aperture therethrough; an interior volume; and toothpaste. Wherein the toothpaste is stored within the interior volume and is adapted to flow through the distal end aperture. Wherein the toothpaste container is located within the hollow interior volume of the elongated main body. [0009] Wherein the slider member is slidably connected to the elongated main body via the slot, and is adapted to push upon the toothpaste container so as to thereby push the toothpaste through the distal end aperture thereof and through the distal end aperture of the hollow interior volume.

[0010] The brush head includes: a proximal end having an aperture therethrough; a mid-section having an aperture therethrough; a hollow interior volume; a tongue scraper; and a plurality of bristles.

[0011] Wherein the hollow interior volume extends between the proximal end and the mid-section. Wherein said tongue scraper is attached to an exterior surface thereof and is adapted to be used to scrape the tongue of a user. Wherein the plurality of bristles are attached to and extend from an exterior surface of the mid-section of the brush head and spaced from the tongue scraper. Wherein the proximal end is connected to the distal end of the elongated main body such that the aperture of the distal end of the elongated main body aligns with the proximal end of the brush head and the toothpaste of the toothpaste container can pass therethrough and out of the aperture of the mid-section of the brush head and between the plurality of bristles.
