ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to toothbrushes and more particularly pertains to a new toothbrush with paste dispenser for brushing teeth.
2. Description of the Prior Art
The use of toothbrushes is known in the prior art. More specifically, toothbrushes heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
Known prior art includes U.S. Pat. Nos. 5,066,155; 4,291,995; 1,362,937; 4,277,194; 4,890,732; and Des. 378,957.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new toothbrush with paste dispenser. The inventive device includes a housing with a reservoir portion and a head portion extending from the reservoir portion. The reservoir portion has toothpaste therein. The head portion has a plurality of bristles coupled to a bristled portion thereof. The head portion has a tube extending therethrough an opening in the bristled portion and in communication with the reservoir portion. The toothpaste is forced through the tube such that a portion of the toothpaste and dispensed onto the bristles. An ejection means ejects the toothpaste from the reservoir portion.
In these respects, the toothbrush with paste dispenser according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of brushing teeth.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of toothbrushes now present in the prior art, the present invention provides a new toothbrush with paste dispenser construction wherein the same can be utilized for brushing teeth.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new toothbrush with paste dispenser apparatus and method which has many of the advantages of the toothbrushes mentioned heretofore and many novel features that result in a new toothbrush with paste dispenser which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art toothbrushes, either alone or in any combination thereof.
To attain this, the present invention generally comprises a housing with a reservoir portion and a head portion extending from the reservoir portion. The reservoir portion has toothpaste therein. The head portion has a plurality of bristles coupled to a bristled portion thereof. The head portion has a tube extending therethrough an opening in the bristled portion and in communication with the reservoir portion. The toothpaste is forced through the tube such that a portion of the toothpaste and dispensed onto the bristles. An ejection means ejects the toothpaste from the reservoir portion.
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 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 of 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 description 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 regarded 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 toothbrush with paste dispenser apparatus and method which has many of the advantages of the toothbrushes mentioned heretofore and many novel features that result in a new toothbrush with paste dispenser which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art toothbrushes, either alone or in any combination thereof.
It is another object of the present invention to provide a new toothbrush with paste dispenser which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new toothbrush with paste dispenser which is of a durable and reliable construction.
An even further object of the present invention is to provide a new toothbrush with paste dispenser which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such toothbrush with paste dispenser economically available to the buying public.
Still yet another object of the present invention is to provide a new toothbrush with paste dispenser which provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith.
Still another object of the present invention is to provide a new toothbrush with paste dispenser for brushing teeth.
Yet another object of the present invention is to provide a new toothbrush with paste dispenser which includes a housing with a reservoir portion and a head portion extending from the reservoir portion. The reservoir portion has toothpaste therein. The head portion has a plurality of bristles coupled to a bristled portion thereof. The head portion has a tube extending therethrough an opening in the bristled portion and in communication with the reservoir portion. The toothpaste is forced through the tube such that a portion of the toothpaste and dispensed onto the bristles. An ejection means ejects the toothpaste from the reservoir portion.
Still yet another object of the present invention is to provide a new toothbrush with paste dispenser that may be disposable, thereby urging the user to replace the toothbrush when all of the paste is gone rather than using the toothbrush after the bristles begin to lose effectiveness.
These together with other objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be made to the accompanying drawings and descriptive matter in which there are illustrated preferred embodiments of the invention.
