Disposable Toothbrush with In-built Toothpaste Reservoir
Presently available toothbrush designs with in-built toothpaste reservoirs, have been based upon a host of ways to activate a piston inside the toothbrush handle, to extrude the contained toothpaste at the brush head.
Little effort has been concentrated upon how evenly, the extruded toothpaste is presented within the bristle area, prior to use.
The present invention, addresses this problem through the utilisation of a common conduit within the brush head, which branches into three shorter conduits, which serve as separate points of emergence to assist in more even dispersion of the extruded toothpaste, throughout the bristle area.
Further to this, the present invention relates to a toothbrush that has toothpaste, stored in an in-built reservoir, (formed by a hollowed section within the handle of the toothbrush) and a means of transferring that stored toothpaste, where it may be used at the head of the toothbrush.
The transferral of toothpaste from this reservoir within the handle, is conducted by means of a plunger assembly, mounted within this handle/reservoir and behind the stored area of toothpaste. By depressing the plunger inwardly towards the Λhead' of the toothbrush, toothpaste is conveyed from the reservoir through a network of conduits, to exit points, located within the head of the toothbrush, adjacent to the base of the cleaning bristles. Moistening of this area, with water now makes the toothbrush ready for use. The present invention will be better understood with reference to the attached drawing, "Drawing 1 of 1", where Figure 1 is a Plan View of the present invention, with hidden outlines depicted and Figure 2 is a Sectional Front Elevation of the present invention.
With reference to figure 1 and/or Figure 2 of Drawing 1 of 1, cap 1 is fitted to handle/reservoir 3 to protect plunger 2 from unintentional depression.
Handle/reservoir 3 is snap fitted' into head and bristle assembly 5.
Toothpaste 4 is contained ahead of plunger 2, in handle/reservoir 3, ready to be transferred to head and bristle assembly 5, (via conduits 6) through depression of plunger 2.
Upon such depression of plunger 2, toothpaste conveyed through channel 6, emerges at three exit points 7 at the base of the bristle components of head and bristle assembly 5.
Wetting of the emerged toothpaste and the bristle components of head and bristle assembly 5, renders the present invention, ready for use.
In the present invention, head and bristle assembly 5, is comprised of two matching components, so that the system of conduits may be produced, as described above. These matching components are 'snap-fitted' together by virtue of special projections and corresponding indentations (not visible in Fig. 1 or Fig. 2) that are moulded into each of these matching components. However, in some circumstances, particularly with contained toothpaste of very high viscosity it may become evident that stronger joining methods for these components of head and bristle assembly 5, will need to be employed. In such a circumstance, these two components of head and bristle assembly 5 may be joined by virtue of automated welding methods (such as high frequency (and ultra high frequency) welding) as commonly used, to join moulded plastic components.
Similarly, should these two components of head and bristle assembly 5 be moulded in plastic types that are conducive to joining by adhesive methods, then such methods may also be employed for joining.
