2. Claims. (Cl. 15-=-136) The herein disclosed invention relates to shaving brushes and has for an object to provide a shaving brush utilizing as the handle a collapsible disposable receptacle in which the soap is contained and which upon squeezing injects the soap into the spaces between the bristles of the brush.

Another object of the invention resides in providing a construction in which leakage is prevented.

A still further object of the invention resides in providing a brush having a body with a cavity therein and bristles mounted in and issuing from the body and in further providing a flexible receptacle having a neck received within said cavity andhaving an opening therein and in further providing a stopper received in said opening and closing the receptacle.

Another object of the invention resides in constructing said stopper with a nozzle projecting outwardly therefrom and said body with a conical seat against which said nozzle is seated.

An object of the invention resides in constructing the stopper with a shoulder engageable with the end of the neck, and the neck and body with threads adapted to urge the nozzle against the seat and the neck against the shoulder.

A feature of the invention resides in providing a tube attached to and extending inwardly into the receptacle for bringing the spaces between the bristles into communication with the interior of the receptacle.

Other objects of the invention reside in the novel combination and arrangement of parts and in the details of construction hereinafter illustrated and/or described.

In the drawing:

Fig. 1 is an inverted end View of a shaving brush illustrating an embodiment of the invention.

Fig. 2 is an elevational longitudinal sectional view taken on line 22 of Fig. 1.

Fig. 3 is a cross sectional view taken on line 3-3 of Fig. 2.

In the drawing a shaving brush has been shown comprising a body having bristles attached thereto and extending outwardly therefrom. Associated with the body is a collapsible disposable receptacle constructed with a neck issuing outwardly therefrom. The body is formed with a cavity in which the neck extends and threads acting between the neck body serve to attach the receptacle to the body. The neck of the receptacle is constructed with an opening closed by means of a stopper. The stop per has a conical shaped nozzle projecting outwardly therefrom and which is adapted to seat on a conical seat formed in the body. This nozzle extends through an opening in the body and into a passageway formed in the bristles of the brush. A tube attached to said stopper and extending inwardly into the receptacle brings the interior of the receptacle into communication with the passageway in the bristles whereby the soap may be injected into the spaces between the bristles when the tube is collapsed. The stopper is formed with a shoulder engageable with the end of the neck and which is urged into engagement therewith concurrently with the nozzle being urged into engagement with said seat upon screwing of the neck into the body.

'The invention consists of a body 10 constructed of some plastic material adapted to be molded and formed into the desired shape. This body has a cavity 11 in one end thereof and a bore 12 in its other end and communicating with said cavity. In the bore 12 are cast bristles 13 which are held in place by means of an adhesive adapted to solidify upon setting which impregnates the bristles and forms an end structure at the base of the bristles. This end structure is formed with an opening 16 therein communicating with an axial passageway 17 in the bristles 13 and which in turn communicates with the space between the bristles outwardly of the body.

Cooperating with the body 10 is a collapsible receptacle 18 constructed of some suitable flexible plastic material adapted to collapse when pressure is applied to the same. The receptacle 18 has a wall structure 19 and a base 21 connected thereto and situated at one end of said wall structure. The other end of the wall structure has issuing inwardly therefrom a flange 22 which terminates in an outwardly extending neck 23. The body 10 is constructed with internal threads 24 while the neck 23 is constructed with external threads 25 adapted to screw into the threads 24 and hold the receptacle attached to the body. The neck 23 is further constructed with an axial opening 26 through which soap may be inserted into the receptacle.

For closing the opening 26 a stopper 27 is employed which is adapted to be inserted into said opening. This stopper is constructed with a nozzle 28 projecting outwardly therefrom having a tip 31 and an adjoining conical portion adapted to seat against a conical seat 15 formed on the end structure 14 in the body 10 and encircling the opening 16 therein. The said stopper is also constructed with a shoulder 29 adapted to seat against the end 30 of said neck. The tip 31 of the nozzle 28 extends through the opening 16 and into the passageway 17. This nozzle has a passageway 32 communicating with the passageway 17 in the bristles 13 and also with the bore 33 of a tube 34. Tube 34 is received in a socket 35 formed in the stopper 27 which terminates short of the nozzle 28 and said tube extends inwardly into the receptacle 18 to within a short distance of the base 21 of said receptacle.

In the manufacture of the receptacle the same is filled with soap and the stopper 27 having the tube 34 attached thereto inserted into the opening 26 in said receptacle. A temporary cap, not shown in the drawings, is then screwed on the threads 25 of the receptacle to close the same until desired for use. In the use of the invention the temporary cap is first removed and discarded. The receptacle 18 is then screwed into threads 24 in body 10 until the parts occupy the position shown in Fig. 2. When properly applied the nozzle 28 is seated on seat 15 and shoulder 29 engages the end 30 of neck 23. Soap may now be injected into the passageway 17 in bristles 13 and from said passageway the soap finds its way into the spaces between the bristles. This is accomplished by squeezing the wall structure 19 of receptacle 18. When a sufiicient quantity of soap has been injected into the bristles the brush is used in the customary manner.

The advantages of the invention are manifest. The device is extremely simple and foolproof and avoids the r' mess ordinarily encountered in the use of shaving soap applied to the brush in the customary manner. By means of the seat formed in the body of the brush and against which the nozzle seats, leakage of soap out of the handle of the brush is prevented. At the same time the shoulder on the stopper prevents leakage between the stopper and the receptacle. When the parts are screwed together the threads simultaneously urge the shoulder against the neck and the stopper against the seat. The device can be constructed at a nominal expense and will operate indefinitely without inconvenience. If desired, the parts can be readily disassembled and cleaned. When the receptacle is empty the same can be removed and discarded and a new filled receptacle substituted.

Changes in the specific form of the invention, as herein described, may be made within the scope of what is claimed without departing from the spirit of the invention.

Having described the invention, what is claimed as new and desired to be protected by Letters Patent is:
