Jan. 3, 1956 s. c. HARVEY LATHER FOAM DISPENSER Filed April 5, 1951 United States PatentO LATHER FOAM DISPENSER Salmon C. Harvey, Brooklyn, N. Y.

Application April 5, 1951, Serial No. 219,400

1 Claim. (Cl. 299-90) This invention relates to a shaving brush construction.

It is an object of this invention to provide a shaving brush construction with a dispensing handle adapted to contain the soap solution and which can be squeezed to elfect a discharge of the soap solution to the brush bristles and wherein the reservoir serves as the handle for the brush.

Other objects of the invention are to provide a shaving brush structure with a removable head having bristles and serving as a cap for the reservoir which is of simple construction, inexpensive to manufacture, has a minimum number of parts, light in weight, compact, sanitary and elficient in use.

For a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

Fig. l is a perspective view of the brush structure embodying the features of the present invention and surrounded by a container in which the same is disposed when not in use.

Fig. 2 is a longitudinal sectional view of the brush structure.

Fig. 3 is a perspective view of one of the check valve elements.

Fig. 4 is an elevational view of the structure with the top portion broken away to show the position of the check valve element mounted on the top thereof.

Fig. 5 is an elevational view of the brush structure showing a check valve element in the bottom of the reservoir.

Fig. 6 is a perspective view of the wire which is disposed in the upward end of the tube to diifuse the upward flow of the soap solution, leaving the reservoir and to distribute it to all sides of the brush bristles.

Referring now to the figures, 10 represents a handle reservoir formed of flexible plastic and of the nature of a squeeze bottle, now commonly in use and having a neck 11 that is threaded to receive a cap 12 that carries a brush structure 13. This brush structure includes forwardly extending bristles 14. The brush structure is threaded upon the neck 11 of the reservoir and can be easily removed to refill the reservoir with the soap solution. In the top of the reservoir there is provided a check valve element 15 that will permit the insertion of air into the reservoir. A similar check valve element 16 can be provided in the bottom of the reservoir.

These check valve elements are shown in Fig. 3 to include a rounded top shaped formation closed at its end to provide cross slits 17 and a flange 18. Air will pass downwardly into the top shaped formation of the element and through the slits as the pressure on the sides of the reservoir is released. Upon applying pressure, for prac tical purposes no liquid can. escape. A long tube 19 is fixed within the opening in the neck portion 11 and extends downwardly into the bottle and to the bottom thereof. This tube extends also upwardly through a bore 26 in the brush structure. A wire element 21 is disposed in the upper end of the tube 19 in order that the liquid as it is projected from the tube will be distributed well within an opening 22 in the brush bristles 14 to distribute it upon all sides thereof. Upon applying the brush to the face, the lather will form thereon. It will be seen that there has been provided a reservoir that serves as a handle for the brush. The brush structure is detachable from the reservoir or handle. The reservoir can be used again and refilled or it can be made sufl'iciently cheap so that it can be thrown away when the contents thereof have been spent.

The brush structure is made of the conventional badger, of nylon or cow hair.

The tube 19 is of semi-flexible plastic and extends the entire length of the reservoir. It tightly fits within the opening within the brush base 13.

If the reservoir is delivered without the brush structure, an extra cap can be provided and the tube 19 can be made a part of the brush structure.

The reservoir is pierced at various places for receiving the tight fitting check valve elements 15and 16. There may be one or several of these elements in the reservoir and they may be disposed in the base alone, as shown in Fig. 5, or any place around the neck, as shown in Fig. 4, and as indicated at 15. There may be a series of such elements around the neck or around the bottom.

The reservoir contains a fluid soap solution which can lather rapidly. It is delivered to the brush bristles by lightly pressing in on the sides of the reservoir. The reservoir immediately regains its shape by the action of the check valve elements, which suck air in when pressure on the reservoir is released. Without these valve elements, the reservoir could not regain its former shape because of the extremely high viscosity of the soap solution, which acts as a barrier to the intake of air through the tube 19 and moreover mats the bristles around the upper end of the tube 19 so that at times air intake is impossible. The wire loop pin 21 has a double action in that it forks the soap stream and delivers it to each side of the brush and it acts as a ball valve preventing any spilling of the solution regardless of the position of the brush, and its combined reservoir.

It is to be understood that the check valve elements 15 and 16 may be made from rubber, synthetic rubber or any other desirable material.

When shaving, the brush is first moistened in Water. The soap solution is then delivered to the tip of the brush as above described, and then the dry beard is lathered. For sanitary purposes a container 23 having a screw perforated cover 24 may be provided. When the brush is not in use, it can be kept in this container.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.

What is claimed is:

A lather foam dispenser for use with a brush including the combination of a flexible reservoir having a threaded neck at one end thereof with an outlet port therethrough providing an outlet for said reservoir, an elongated flexible tube extending inwards through said port in said neck into the reservoir, a cap with an internal thread fitting upon the threaded neck, said cap having an opening registering with the outlet port of said neck for receiving the outer end of said flexible tube therethrough so that said outer end opens to the surface of said cap, and a check valve in an end wall of said flexible reservoir, a short wire loop having the engaging ends twisted relative to each other, said engaging ends being disposed in the outer end of said tube and the loop portion extending a short distance from the end beyond the outer end of the said cap.
