ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a heat tank apparatus and more particularly pertains to a new substance holding and heating apparatus for preventing sand and water from freezing.
2. Description of the Prior Art
The use of heat tank apparatus is known in the prior art. More specifically, heat tank apparatus 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. No. 5,193,906; U.S. Pat. No. 121,351; U.S. Pat. No. 1,875,516; U.S. Pat. No. 4,452,535; U.S. Pat. No. 277,277; and U.S. Pat. No. Des. 373,021.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new substance holding and heating apparatus. The inventive device includes a rectangular base member which is essentially a housing, and also includes a substance holding member having side walls and being securely disposed upon the housing and extending upwardly therefrom, and further includes a lid member having a top wall and side walls extending downwardly from the edges of the top wall and further having a handle member securely attached to an exterior of the top wall with the lid member being closeable over the open top of the substance holding member, and also includes a heating element diposed inside the housing and beneath the substance holding member, a switch member connected to the heating element, and a power cord connected to the switch member and being adapted to plug into a power source.
In these respects, the substance holding and heating apparatus 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 preventing sand and water from freezing.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of heat tank apparatus now present in the prior art, the present invention provides a new substance holding and heating apparatus construction wherein the same can be utilized for preventing sand and water from freezing.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new substance holding and heating apparatus which has many of the advantages of the heat tank apparatus mentioned heretofore and many novel features that result in a new substance holding and heating apparatus which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art heat tank apparatus, either alone or in any combination thereof.
To attain this, the present invention generally comprises a rectangular base member which is essentially a housing, and also includes a substance holding member having side walls and being securely disposed upon the housing and extending upwardly therefrom, and further includes a lid member having a top wall and side walls extending downwardly from the edges of the top wall and further having a handle member securely attached to an exterior of the top wall with the lid member being closeable over the open top of the substance holding member, and also includes a heating element diposed inside the housing and beneath the substance holding member, a switch member connected to the heating element, and a power cord connected to the switch member and being adapted to plug into a power source.
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.
Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application. The abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
It is therefore an object of the present invention to provide a new substance holding and heating apparatus which has many of the advantages of the heat tank apparatus mentioned heretofore and many novel features that result in a new substance holding and heating apparatus which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art heat tank apparatus, either alone or in any combination thereof.
It is another object of the present invention to provide a new substance holding and heating apparatus which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new substance holding and heating apparatus which is of a durable and reliable construction.
An even further object of the present invention is to provide a new substance holding and heating apparatus 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 substance holding and heating apparatus economically available to the buying public.
Still yet another object of the present invention is to provide a new substance holding and heating apparatus 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 substance holding and heating apparatus for preventing sand and water from freezing.
Yet another object of the present invention is to provide a new substance holding and heating apparatus which includes a rectangular base member which is essentially a housing, and also includes a substance holding member having side walls and being securely disposed upon the housing and extending upwardly therefrom, and further includes a lid member having a top wall and side walls extending downwardly from the edges of the top wall and further having a handle member securely attached to an exterior of the top wall with the lid member being closeable over the open top of the substance holding member, and also includes a heating element diposed inside the housing and beneath the substance holding member, a switch member connected to the heating element, and a power cord connected to the switch member and being adapted to plug into a power source.
Still yet another ob
