Description

DISPENSER H. W. JENNINGS Filed Jan. 30, 1939 INVENTOR.

ATTORNEYS.

Patented Apr. 23, 1940 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to the art of dispensing containers adapted especially for vanity powder to be carried in the ladys purse.

Heretofore it has been the practice to waste face powder by taking from the vanity more than actually required at any given time, since there has been no means for dispensing the powder in any predetermined quantity or for discouraging waste.

It is, therefore, the object of my present invention to devise a neat and compact form of container with means for dispensing the powder therefrom in predetermined quantity.

A further object is to provide such a device in which the structure is decidedly simple and which can be manufactured and assembled with comparative ease and in which the powder supply can be renewed from time to time in a very simple manner.

Other objects will appear from the following description and claims when considered together with the accompanying drawing.

Fig. 1 is an elevation of my improved form of device; and

Fig. 2 is a vertical section therethrough.

It is to be understood that the present form of disclosure is merely for the purpose of illustration and that there may be devised various modifications Without departing from the spirit of this invention as herein set forth and claimed.

In the present specific form of disclosure, the main body I of the container has the readily removable front and rear ends 2 and 3, respectively, which are here shown as having screwthreaded engagement. The front end has a centrally disposed discharge opening 2a of cylindrical form which is adapted to be closed by the correspondingly formed portion 4 on the forward end of the plunger rod 5. That is, the portion 6 is of substantially the same size as the discharge opening so as to allow a sliding fit for movement of the closure portion 4 through the opening 2a. The main body of the rod 5 is of the same form and size and there is provided an annular concave reduced portion (5 immediately to the rear of the closure portion 4, this reduced portion being so formed and arranged that it will occupy position within as well as forwardly and rearwardly of the discharge opening when the same is opened by forward movement of the plunger rod 5.

Near the rear end of the rod 5 there is mounted the plunger which comprises the metal disks 1 and 8 and the intermediate leather disk 9 which are held together by the nuts H! on the rod 5.

The disks 7 and 8 are free of the inner surface of the container wall while the leather disk 9 has sealing engagement with the container wall for effective plunger action. Upon the extreme rear end of the rod 5 there is the nut H which I is adapted to be engaged by the hand or finger of the user in order to actuate the plunger, as will be readily understood. The nut II will serve also to limit the extent of movement forwardly of the plunger as it engages the rear end of the 10' container, while the nut ID at the rear of the plunger will serve to limit the extent of the rearward movement of the plunger. The plunger is normally forced rearwardly by the coil spring l3 which has abutment against the front end of 1 the container and against the plunger. The spring l3 will serve also as a means of agitating the powder, during actuation of the spring, so as to prevent or overcome any caking of the powder within the container.

Upon pressing the nut II, the forward movement of the plunger will cause a certain air pressure to be built up within the container before the rod 5 has been moved sufficiently to remove the portion l from the discharge open- 25 ing 2. Then when the closure portion 4 has been moved out of the opening 2, such air pressure and that caused by the further forward movement of'the plunger will cause the ejection of powder through the clearance allowed by the reduced portion 6. As the powder is forced in more or less of a blast past the reduced portion 6 within the discharge opening during the discharge period, the discharged powder will strike against the larger portion of the rod just forward 35 of the reduced portion 6, with the result that the powder will be deflected in more or less of a spray upon the hand or pad which receives the powder for application to the face of the user.

It will be observed that the end 3 has a flange 40 3a. and that the nut I I is substantially flush with the flange, the purpose being to have the flange protect the plunger against accidental actuation and also to add to the appearance of the device.

It is to be noted also that the front end 2 can 45 be readily removed without disturbing the rest of the device, the container can then be refilled with powder and the end closure replaced for continued use in the manner explained. In order to re-fill the container, this may be done by 50 emptying the contents of a pack of predetermined quantity corresponding to the capacity of the container, these filled packs to be supplied by the merchant. Or, loose powder can be filled into the container; or it may be filled in any 55 other suitable manner. In any event, this device possesses the advantage of being readily refilled by virtue of the convenient manner in which the front end can be removed and then replaced after re-filling the container and without disturbing the rest of the device.

The container can be made of any suitable form] of material as for instance the many attractive composition materials which are available in various colors .for decorative purposes. This device can be manufactured and sold at a popular price and is thought to serve a very useful purpose in a most efiicient manner. It is .to be understood, of course, that this same dispenser structure can be used in connection with various forms of powder and other materials as well.

What I claim is:

1. A dispenser comprising a container having a removable front end with a centrally located dispensing opening therethrough, a single plunger rod extending co-axially through said discharge opening and through the rear end of the container, said rod having a forward end portion of the same cross section as said discharge opening so as to constitute a sliding fit closure for said opening, said rod having also a reduced portion immediately to the rear of said closureportion so arranged as to occupy position in the opening and permit discharge of the contents past said reduced portion and out through said discharge opening when the closure is in open position, a plunger on said rod for forcing the contents forwardly, and a spring normally tending to force said plunger towards withdrawn position and said closure towards closed position.

2. A dispenser comprising a container having a removable front end with a centrally located cylindrical opening for discharge therethrough, a single cylindrical plunger rod extending co-axially through said discharge opening and through the rear .end of the container, said rod having a forward end portion of the same cross section as said discharge opening so as to constitute a sliding fit closure for said opening, and said rod having a sliding fit through also said rear end of the container, said rod having a reduced portion immediately to the rear of said closure portion so arranged as to occupy position in the opening and permit discharge of the contents past said reduced portion when the closure occupies open position, a plunger on said rod for forcing the contents forwardly out through said discharge opening, a coil spring surrounding said rod and having abutment against said plunger and said front end so as to normally force said plunger towards Withdrawn position and. said closure towards closed position and so as to serve also as an agitator for the contents, and stop means on said rod adapted toengage the inside and outside of the rear end of the container so as to limit the extent of movement of the plunger in both directions.
