Abstract

A hinged door dispensing toothbrush includes a localized toothpaste filled reservoir comprising only the top quarter (or one fifth ⅕) of the toothbrush. No piston is required. The toothpaste is filled and localized directly behind the bristles for easy application. A hinged door located proximately behind the bristles doubles as both plunger to communicate the toothpaste on the bristles through a hole(s) near the bristles and as a loading device revealing an open chamber or magazine for loading toothpaste pellets. After loading the tooth paste pellets in the toothbrush and closing the hinged door, application of toothpaste onto the bristles occurs by pressing the hinged door plunger forcing toothpaste onto the bristles.

Description

The improvement regarding cleanliness enables the toothbrush to be used on multiple occasions making it different than several other U.S. patents (including U.S. Pat. No. 7,331,731) regarding dispensing toothbrushes that are disposable.

BRIEF SUMMARY AND DESCRIPTION

The object of the hinged door dispensing toothbrush is to provide an environmentally safe ‘one for all’ toothbrush for the user. Cleanliness is the cornerstone in the reliable design of this dispensing brush. The toothbrush as designed is operated by sliding the latch that holds the hinged door shut inserting toothpaste (or toothpaste pellets); shutting the hinged door; sliding the latch shut and then placing the thumb with force on the hinged door plunger moving toothpaste through hole(s) onto the bristles. After use, the user re-opens the hinged device washing it out readying the device for continued use.

BRIEF DESCRIPTION OF DRAWING

Attached with this application is a single drawing showing the toothbrush from three views: the top, bottom and side view. Also shown independently is the hinged door bubble applicator. The top view shows the latch that is described above that releases the hinged door bubble applicator. The side view shows the hinged door bubble door applicator in its opened view. The bottom view simply shows the other side of the toothbrush with bristles.

Claims

1. A simple designed hinged door doubling as both a loading chamber or magazine to load toothpaste pellets and an applicator being a self contained bubble plunger located within the hinged door. It is materially different than U.S. Pat. No. 7,478,960 in that does not contain or require a piston. Localization of the toothpaste pellets behind the bristles allows pressure from the adjacent bubbled door plunger to apply the toothpaste within the bristles. It is also materially different from U.S. Pat. No. 7,350,526 in that the bubble applicator does not slip over the toothbrush devise, but is located within a hinged door that allows both loading and application (i.e. the bubble is actually part of the device). One major improvement of this design over all other dispensing toothbrush designs is it can be cleaned by opening the hinged door and washing it out; a major improvement for safety and cleanliness. The simple designed hinged door also makes it materially different than U.S. Pat. No. 7,367,737 in that toothpaste does not have to travel through the length of a hollow shaft once again improving cleanliness.
