The invention relates to a toothbrush, having a head and a handle, wherein the head is provided with bristles.
Conventional toothbrushes (RU 2032366) have several disadvantages. For one, their hygienic properties are insufficient. In particular, bacteria can multiply unimpedingly in unused toothbrushes. Furthermore, they only perform one function, namely, for dental hygiene.
It is the object of the invention to further develop this known toothbrush in such a way that the materials from a toothpaste tube employed for dental hygiene are optimally utilized, while at the same time, contributing to the protection of the environment.
The stated object is attained by means of the characteristics of claim 1.
The basic idea of the invention is not only to design the conventional toothbrush to be more hygienic, but to develop it further, so that it also performs additional functions. In accordance with the invention it is designed to remove unused toothpaste from a tube in a better and simpler manner. Improved hygienic properties are achieved because, for example, the bristles are provided with antiseptic materials. In addition to conventional antiseptic materials, silver and other materials are used. A permanent hygienic effect of the silver is assured if the bristles are provided with a thin layer of silver. On its exterior circumference, the head of the toothbrush is provided with elastic massage elements for the gums, which are preferably arranged in parallel. A slit is cut into and through the handle of the toothbrush, wherein its length is equal to the width of a tube of toothpaste whose contents have been mostly squeezed out, and its width is equal to the thickness of a tube of toothpaste whose contents have been mostly squeezed out.
The initially emptied portion of the toothpaste tube can be inserted into the slit, and adjusted in such a way that more toothpaste can be squeezed out of the tube of toothpaste. Therefore, the toothpaste contained in the toothpaste tube can, for all practical purposes, be completely squeezed out of the toothpaste tube, so that the empty toothpaste tube can be disposed of without harming the environment.
Further advantageous embodiments of the toothbrush are apparent in the dependent claims.
It is thus possible to provide for a toothbrush that is further provided with a slit to be cut parallel to the width of the handle, or cut perpendicularly in respect to the width of the handle.
The ends of the slit terminate, convexly arched, in the handle, so that no sharp broken edges can be created at these locations when the toothpaste tube is pulled through the slit for squeezing out toothpaste.
The areas of the handle which have been weakened because of the slit can be substantially reinforced in that, in the one case, elastic metal elements are embedded in the handle underneath and above the slit or, in the other case, elastic metal elements are embedded next to the slit on both sides of the handle. Here, the elastic metal elements can extend past the length of the slit into the handle, and can preferably be injection-molded into the handle.
The head with the bristles can be an exchangeable part connected with the handle containing the slit. Differently designed heads can be connected in this way with the handle, so that only standardized heads with different bristles can be employed. In this way, careful cleaning of the teeth can be performed, good care can be given to the tongue and mouth, and the gums can be massaged.
The invention will be explained in greater detail by means of an exemplary embodiment represented in the drawings.
The invention relates to a toothbrush, having a head and a handle, wherein the head is provided with bristles. So that the toothbrush can be used for squeezing toothpaste out of a squeezed- together toothpaste tube, the invention provides that a slit is cut into the handle, and is matched in its length to the width of a squeezed-out toothpaste tube, and in its width to the thickness of a squeezed-out toothpaste tube.
So that no sharp broken edges are created at the ends of the slit, there is a concavely arched transition into the handle at the ends of the slit. Furthermore, elastic metal elements are embedded in the handle underneath and above the slit, and extend past the ends of the slit into the handle, and are embedded into the handle. Also, elastic metal elements reinforce the handle in the area of the slit, so that the weakened parts of the handle in the area of the slit can provide a considerably stronger pressure force to a toothpaste tube introduced into the slit.
10. Toothbrush head
The toothbrush has a head 10 with bristles 11 inserted into it. The head 10 is connected in one piece with a handle 13, having a slit 14 cut into it. The head 10 with the bristles 11 and the handle 13 with the slit 14 can also be embodied as separate pieces and can be connected with each other, for example, by means of a screw connection. This separation makes it possible to selectively connect differently designed heads 10 with bristles 11 to the same handle 13 having a slit 14, in order to expand the range of application and use of the toothbrush.
As represented in the exemplary embodiment in accordance with
So that no sharp broken edges are created at the ends of the slit 14, there is a concavely arched transition into the handle 13 at the ends of the slit 14. As
Elastic metal elements 15 and 16 reinforce the handle 13 in the area of the slit 14, so that the weakened parts of the handle 13 in the area of the slit 14 can provide a considerably stronger pressure force to a toothpaste tube introduced into the slit 14.
In the view of the above, on the broad side of the handle 13 in accordance with
