ABSTRACT:
BACKGROUND OF THE INVENTION
1). Field of the Invention
The field of this invention is directed to whistles designed to be placed within the mouth of a human and used to produce a high pitched shrill sound by blowing air through the whistle.
2). Description of the prior Art
The construction of whistles has long been known also the construction of whistles out of a confectionery product, such as hard candy, has long been known. However, heretofore, whistles constructed of the prior art have not been designed in such a way as to maximize the creation of a high pitched shrill sound.
Whistles are commonly used as a self entertainment device. However, whistles do have utility in that they may be used as a means of getting someone's attention located at some distance away from the whistler. Also, whistles can be used as a means of instructing animals to do certain things, such as calling cows to a barn.
A primary objective of the present invention is to construct a whistle of superior quality than previously constructed whistles that are able to produce an extremely loud high pitched shrill sound.
Another objective of the present invention is to construct a whistle which can be readily manufactured from either a permanent type of material, such as plastic, or can be manufactured from an edible material such as a hard candy.
Another objective of the present invention is to construct a whistle which can be manufactured inexpensively and thereby sold to the ultimate consumer at an inexpensive price.
The whistle of the present invention is constructed of a body which has a top wall and a bottom wall which are interconnected by a sidewall. An air entry through hole is formed between the top wall and the bottom wall with this air entry through hole being located directly adjacent the sidewall. Formed within the body is an air exhaust chamber which is tapered and has straight walls connected between a narrow tip and a widened base. The air entry through hole connects with the narrowed tip. The widened base forms an air exhaust opening within the top wall. The air exhaust chamber is slantingly located within the body permitting a support stick to be mounted within the body. The portion of the body including the air entry hole is to be located within a mouth of a user, and by forcing air into the air entry opening and into the air exhaust chamber a high pitched shrill sound is produced.
