SUMMARY OF THE INVENTION
The present invention is that of a newly designed toothbrush that has a replaceable head. The head of the toothbrush and the base of the toothbrush would have complimentary dove tail shapes ensuring that the pieces would fit together snugly. In addition, the present invention would have a mechanism for securing the two components together. The mechanism would either allow the brush head to be secured to the handle with a locking pin that slips through the head and into a hole in the base of the toothbrush, or alternatively, a locking tab that snaps into the hole in the brush handle.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of descriptions and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regard as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
It is therefore an object of the present invention to provide a new and improved toothbrush with a disposable head which has all of the advantages of the prior art and none of the disadvantages.
It is another object of the present invention to provide a new and improved toothbrush with a disposable head which may be easily and efficiently manufactured and marketed.
It is yet another object of the present invention to provide a new and improved toothbrush with a disposable head which is of durable and reliable construction.
It is still another object of the present invention to provide a new and improved toothbrush with a disposable head which is economically affordable and available to the buying public.
Other objects, features and advantages of the present invention will become more readily apparent from the following detailed description of the preferred embodiment when considered with the attached drawings and appended claims.
