Claims.

This invention relates to articles of commerce and anobject of the invention is to provide a tooth brush, enclosed in a wrapper, and the handle of the brush provided with an aperture 5 for receiving a container of dentrifice therein.

Another object of the invention is in the provision of a flexible wall container for dentifrice or the like which may be inserted in anaperture provided in the handle of a tooth brush or the like, the aperture being of a size to slightly collapse the walls of the container to hold the same 7 in the aperture.

Another object of the invention is to provide a tooth brush provided with an aperture-of a size to slightly compress the walls of a flexible container for dentifrice, to maintain the same in position in. the handle but which will permit the removal of the container by pressure exerted at right angles to the pressure exerted by the side walls of the aperture-upon the container.

Another object "of'the invention is to provide an article of commerce which consists-of a sterilized tooth brush and a quantity of dentifrice 2 sufiicient for only one application and the brush the complete outfit comes to the user in a sterilized condition; Another object of the invention is in the provision of an article of commerce consisting of a 3 tooth brush and a quantity of dentifrice sufiicient for one application the entire package being so cheaply made as to permit the user to dispose of the tooth brush after using the same only once. These objects and the several novel features of the invention are hereinafter more fully described and claimed and the preferred form of construction by which these objects are attained is shown in the accompanying drawing in which- I Fig. 1 is a perspective view of the wrapper for the brush. Fig. 2 is a perspective view of the brush and the dentifrice holder installed therein.

Fig. 3 is a section taken substantially on line 3-3 of Fig. 2..

Fig. 4 is a section taken on line 4-4' of Fig. 3. It is a well known fact in oral hygiene that the oral cavity contains a multitude of germs which'are transferred to the tooth brush when the same is applied to the teeth. As a general rule no attempt is made by the average user to sterilize the brush after it has been used'to brush and dentifrice enclosed in a wrapper softhat thereof.

the teeth and in fact it has been found 'impos- (Cl: 15167) w l bristles of the brush. With our device itis intended that the brush be used only for one application and inasmuch asthe brush and dentifrice will come to the user in a sterilized package it will be seen that this unsanitary condition will not exist. as the whole device will be so. cheaply made that the average user can eco-. nomically use one of these brushes every time they desire to'brush their teeth.

Referring to the drawing it will be seen that the brush handle 1 is provided with the usual bristles 2 near one end thereof and the handle on the brush is provided with an aperture 3 extending completely through the handle. A flexible wall container 4, preferably of capsule form, contains a dentifrice which may be in powdered form and by referring to Figs. 3 and 4 it will be seen that the aperture 3 is slightly less in width than the diameter of the container 4 and likewise that the length of the aperture 3 is slightly less than the length of the container 4 so that the container will beheld in place in the handle by pressure on the side walls It will be understood that it is not necessary to have the distance between the end walls of the aperture less than the length of the container 4 as the pressure on the side wallsof the container will be sufficient to hold the same in position in the handle. A wrapp r 5, which may be tubular'ifi' form, is of a size to receive the tooth brush and container 4 therein and the same may be made of cellophane or heavy paper ,or the like. It will be further understood that the amount of dentifrice in the capsule 4 is only sufiicientfor one application to the brush.

When the brush andthe container 4 are re-' moved from the wrapper 5. it is only necessary to apply a slight pressure to the exposed portion of the container 4 to force the same out of the aperture 3. The container may be then disassembled and the dentifrice therein shaken out if in powdered or liquid form or squeezed out 10 if in the form of paste, and applied to the bristles of the brush. Whenthe teeth "have been brushed the tooth brush will preferably be discarded and a new one used when it is desired to brush the teethagain. I 10 From the foregoing description it becomes evident that we have provided an article of commerce consisting of a tooth brush and a container of dentifrice sufficient for a single application both encased in a wrapper so that they will come to the user in a sanitary condition and which will be so cheaply made and sold to the user as to permit him to discard the brush after it has been used one time, thereby preventing germs'from entering the mouth through the bristles of the brush.

Having thus fully described our invention, its utility and mode of operation, what we claim and desire to secure by Letters Patent of the United States is 1. A tooth brush having a handle provided with. an elongated aperture extending completely through the handle and having substantially parallel side walls, a frictionally closed, separableflexible wall container for dentifrice inserted in the aperture and maintained therein by pressure ofthe side walls of the aperture on the Walls of the container.

2. A toothbrush having a handle provided with an aperture extending through the handle, a frictionally closed, separable container for dentifrice inserted in the aperture and maintained therein by pressure of the side walls of the aperture upon the walls of the container.

maintained. in place by pressure exerted by the walls of the aperture on the walls of the con-' tainer.

5. Atooth brush having a handle provided with an elongated aperture extending completely through the handle and having substantially parallel side and end walls, a frictionally closed, separable container for dentifrice capsule like in form inserted therein, and maintained in place by pressure exerted by the side and end walls of the aperture respectively upon the side and end walls of the container. 1
