Patented Apr. 11, 1939 UNITED STATES PATENT OFFICE 2,154,209 COMBINATION TOOTH BRUSH AND SIPPER Jack Kohn, Brooklyn, N. Y. Application June 4, 1937, Serial No. 146,335 1 Claim. (01.299-17) This invention relates to improvements in toothbrushes, and more particularly to a combination tooth brush and water sipper.

During the act of cleansing the teeth by the use of a tooth brush, it is customary for a person to rinse his or her mouth with clean water to carry away any dentifrice which may remain therein. Such tooth cleansing operation is usually performed at a wash basin or sink, but it is considered unsanitary to use a drinking glass usually provided at a basin or sink for drinking convenience, to assist in the cleansing of the mouth with water after a tooth brushing operation. Furthermore, conditions arise where a drinking glass is not available to a person when brushing the teeth which prevents rinsing of the mouth. It is therefore one of the main features of this invention to provide a novel tooth brush which may be used by the owner thereof in the manner of a straw or sipper to draw fresh water from beneath a flowing faucet or tap directly into the mouth to effect rinsing of the mouth after a tooth brushing operation.

Another feature of the invention resides in a combined tooth brush and water sipper in which the handle of the brush is utilized as a mouth piece, and through which fresh water may be drawn into the mouth of a user, it being first necessary to prime the water passage in the handle by momentarily holding the water inlet end of the passage beneath a stream of water and trap a supply therein, after which the desired suction is created by drawing at the outlet end of the handle and while still holding the tooth brush beneath the water stream, a continuous flow of water may be drawn into the mouth of a user until such time as the supply of water is sufficient to perform a thorough rinsing of the mouth. If desired, drinking water may be drawn into the mouth of the owner of a tooth brush by a similar procedure where sanitary drinking containers are unavailable.

A further feature of the invention is the pro vision of a combined tooth brush and water sipper which is simple and inexpensive of construction, convenient to use, and which may be kept in a sanitary condition to the satisfaction of the individual owner of the article.

With these and other objects in view, the invention resides in the certain novel construction, combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claim, and are illustrated in the accompanying drawing, in which:

Figure 1 is a perspective view of my combination article in use as a water sipper.

Figure 2 is a perspective view of the combined tooth brush and sipper per se.

Figure 3 is an enlarged vertical longitudinal sectional view on the line 33 of Figure 2.

Figure 4 is a vertical longitudinal sectional view on the line 4-4 of Figure 3.

Figure 5 is an enlarged vertical transverse'sectional view on the line 5-5 of Figure 2.

Figure 6 is an enlarged vertical transverse 'sectional View on the line 66 of Figure 2.

Referring to the drawing by reference characters, the numeral I0 designates my combined toothbrush and sipper in its entirety, and which includes a relatively fiat elongated handle member I! constructed of any suitable composition material similar to that from which the present tooth brushes are constructed. Formed integral with one end of the handle member II is a relatively flat head H. from which brush bristles l3 extend from the front side thereof.

The handle member H adjacent the free end thereof is provided with a mouth piece [4 which may be gripped between the teeth of the user when the device is employed as a sipper and the cross sectional shape of the mouth piece portion H as shown in Figure 5 enables the lips of the user to closely engage the same.

Extending lengthwise of the handle member H is a bore I5, the outer end of the bore terminating in a circular portion l6 around the eye l'l provided in the handle member II and which eye is utilized in the hanging of the article upon a hook or nail. Communicating with the rounded portion l6 of the bore and extending radially with respect to the axis of the rounded portion are restricted outlet passages 18. The inner end of the bore I5 is joined by branch or forked bores Ill-l9, which bores communicate through a loop 40 portion 20 disposed adjacent the head end of the handle member.

Interposed between the branch bores Ill-I9 and communicating therewith through the loop portion 2!! is a chamber 2| and passing through 5 the top wall of the chamber and opening through the back face of the brush head I2 are closely spaced elongated inlet passages 22. The passages 22 are disposed at an inclined angle in order that water may be drawn therethrough when the article is held in a natural position for use as shown in Figure 1 of the drawing. The inlet passages 22 communicate with the chamber 2| adjacent the closed end thereof in order that a quantity of water may be trapped in the chamber 2| and branch bores |9--l 9 below the level of the lowermost inlet opening 22 in order that the bore l5 may be primed to produce a continuous flow therethrough when the mouthpiece end I4 is placed in the mouth of the user with the head end disposed beneath the water stream of a faucet, as shown in Figure 1 of the drawing.

In use of the combination article, it will be appreciated that the brush portion l3 may be used in the usual manner for brushing the teeth in the same manner as a conventional tooth brush. Instead of the user appropriating a glass of water for rinsing the mouth after the tooth brushing operation to remove the dentifrice from the teeth and the mouth, the user may place the mouth piece end M in his or her mouth as shown in Figure 1, presenting the rear side of the head end of the brush beneath the stream from the faucet F. Before drawing inwardly, the user first waits until the bore [5 has been primed by trapping a quantity of water in the branch bores l9- l9 and lower portion of the chamber 2|. The user then proceeds to draw inwardly, causing the water to be drawn through the bore l5 and out through the restricted outlet passages l8 into the mouth of the user. A continuous stream may be drawn into the mouth by the user permitting the inlet passages 22 to remain in the path of the stream from the faucet F until such time as the desired amount of water has been drawn through the bore [5. The user by accumulating a supply of water in the mouth may thoroughly rinse the teeth and mouth of any dentifrice which may remain therein. Although I have described the article for use in drawing rinsing water into the mouth of the owner of the article, the device may be found useful for drinking purposes where drinking glasses are unavailable.

In view of the fact that the article is intended for individual use, it may be kept in a sanitary condition by the owner by cleansing the same after each use of the article either as a tooth brush or as a sipper.

While I have shown and described what I consider to be the most practical embodiment of my invention, I wish it to be understood that such changes and alterations as come within the scope of the appended claim may be resorted to if desired.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent of the United States, is:-

A sipper device for conveying water from a stream of faucet water into the mouth of a user comprising an elongated member having a mouth piece at one end thereof and a flat head at the other end thereof, a bore extending lengthwise within said member from the mouthpiece end thereof, the inner end of said bore terminating in an elongated loop portion within said fiat head, an elongated chamber within said head and disposed intermediate the branches of said elongated loop portion and opening into the closed end of said loop portion, and a plurality of spaced transversely disposed water inlet openings in one side of said flat head which open on their inner sides into said chamber while their outer sides open onto one of the fiat sides of said flat head.
