differ/24y Patented Mar. 28, 1950 UNITED s'rAri-is PATENT OFFICE DISPOSABLE RAZOR Albert D. Brown, Atlanta, Ga. Application November 19, 1945, Serial No. 629,367
My invention relates to an improvement in shaving devices or safety razors, and has for one purpose to provide a dispensable razor or shaver.
Another purpose is to provide a razor or shaver adapted for a quick and emergency shave for those who find themselves without the usual shaving facilities.
Another purpose is to provide a packaged shaver which includes or carries enough brushless cream for one shave.
Another purpose is to provide an improved package assembly for dispensable shavers.
Other purposes will appear from time to time in the course of the specification and claims.
I illustrate the invention more or less diagrammatically in the accompanying drawings wherein Fig. 1 is a perspective view;
Figure 2 is a similar perspective illustrating the shaver as cut away along the section line 22 of Fig. 1;
Figure 3 is a perspective view of the shaver from a different angle, with a brushless cream container in the removed position.
Figure 4 is a perspective view illustrating a group of packaged shavers arranged in a stack; and
Figure 5 is a perspective view of a single container with its cover partly opened, and with the shaver indicated within the container.
Like parts are indicated by like symbols throughout the specification and drawings.
Referring to the drawings, I generally indicates a shaver body generally comma shaped in longitudinal section, shown as having a tubular portion, 2 with a generally cylindrical aperture, 3 which may be open at one or at both ends. The body has a handle flange or projection 4, one side of which is defined by a convex curved surface 5, shown as continuous with a generally or partially cylindrical surface 2a surrounding the cylindrical portion 2 of the body. The opposite concave face 6 of the member 4 is joined by an arcuate connecting surface I to the more or less cylindrical surface 2a of the body 2. The ends 8 of the body 2 may be plane and parallel. One plane face is shown at 8 in Figure 1. The interior aperture 3 opens to the exterior curved face 5 through a drainage slot 9, shown for example in Figure 2. Located at one side of the slot 9, and preferably permanently molded into the body I, is a razor blade l0 having a sharpened edge I I. The outer edges of the drainage slot 9 terminate in beveled flattened portions l2, 13. The parts are so proportioned in relation to the cutting edge ll of the blade it, that the so blade is properly placed and protected to obtain a safety razor efiect. The corners, or ends of the blade are inset in the body I and the cutting edge is located below or within the curved surface i. It will be noted that the handle portion, or flange 4, is so formed and positioned, in relation to the slot 9 and the razor edge II, that the user can operate the razor by grasping the handle with his fingers and drawing the body portion across the face in any desired direction. I find it desirable to position within the aperture 3 a supply of shaving cream. For example, as shown in Figs. 1 and 3, I illustrate a capsule formed of the telescoped parts 20 and 2|, which contains enough brushless shaving cream for at least one shave.
The body I may be formed of any suitable material. I may employ any suitable plastic, for example, a transparent plastic. I prefer to employ a cheap material in order that the unit may be so priced as to make it practical and economical to use it once and then throw it away. It will be understood, however, that under some circumstances it may be practical to so mount the blade in that it can be removed and replaced. For example, where slightly elastic material is employed for the body, I, the blade may be removably held frictionaily in place at the proper location for shaving. However, I prefer to employ my invention in connection with a disposable shaver, in which the blade is permanently molded into the body, and in which the whole unit may be discarded after a single use.
In dispensing the device, I prefer to provide a sealed container shaped to protect the cutting edge of the blade and to provide minimum stacking space. Referring to Figs. 4 and 5, I illustrate a container which may be of any suitable material such as a transparent plastic, or of opaque material with cellophane or otherwise transparent window portions. With reference to Fig. 5, I illustrate the container as having a rear end wall 30 of maximum height and a front end wall 3 I, of minimum height, and connecting side walls 32 which have inclined upper edges 33 from which folds or tabs 34 are inwardly folded. The cover 35 is bent or hinged as at 36 to the upper edge of the end wall 30 and has a forward flap 31 which may be inserted between the adjacent edges of the flaps 34 and the end wall 3|. A removal tab Ila may be used. It will be observed that when the container thus formed is closed, it holds the dispensable shaver unit in position with the blade edge ll located in the bottom or corner space 38 of the container, where it is out of contact with the container itself and protected by the container. It will be understood that before inserting the shaver in the container, the shaver may be sterilized and the edge of the blade II protected by an oil film. The container, which may be readily formed from a single piece or blank, may be sealed in the closed position. Preferably it is made airtight, for example through the medium of any suitable sealing tape. Any suitable tab 3la. may be provided to permit the easy opening of the container.
The abovedescribed container is so proportioned that it can be stacked in pairs, each pair forming together a rectangular body as shown at small a, small b of Fig. 4. As many pairs as desired, arranged to form such rectangular bodies, may be stacked or packaged in a large container. In Fig. 4 I illustrate six containers arranged in three pairs, which, after being stacked or assembled, may be packaged or handled as a larger unit Also they may be loosely stacked, as shown in Fig. 4, for handy disposition in a show case or on a counter.
It will be realized that whereas I have described and illustrated a practical and operative device, nevertheless many changes may be made in the size, shape, number and disposition of parts, without departing from the spirit of my invention. I therefore wish my description and drawings to be taken as in a broad sense illustrative or diagrammatic, rather than as limiting me to my precise showing.
The use and operation of follows:
My dispensable shaver is adapted to provide a quick emergency shave for those who find themselves without the usual shaving facilities. The shaver is shown as formed with a single plastic body, generally indicated at l with an integral concave-convex handle, and an aperture 3 in which the cream capsule 20, 2| is stored. In order to remove the capsule all that the user has to do is to tilt the body i and to permit the capsule to drop out by gravity. The user then. separates the capsule parts 20, 2| and applies the the invention are as cream to his face. The inside curved surface 6,
1 provides an efficient resting place for the second joint of the second finger, the thumb and index finger, grasping the ends of the body I. For shaving the upper lip downwardly the handle portion 4 of the body may be grasped with the thumb on the convex side and the index and second finger on the concave side. For shaving upwardly the shaver body is inverted and theindex finger is placed on the concave curved portion 6, I with the thumb and second finger grasping the ends of the body. Thus, I have provided a simple, small, compact shaving body which is adapted for shaving in a variety of directions and with a variety of finger The general contour of the shaver, in connection with the fact that the edge if has no exposed corners and is located within the curved surface 5, makes the likelihood of less than that arising from the use of the conventional safety razors now on the market. The shaver can be supplied as a sterilized article and can therefore be stored for long periods without deterioration. The blade is protected from rust by the oil film, and the shape of the container, as shown in Figs. 4 and 5, is such that the shaver and its blade are protected from injury in handling. The unit is self-contained and includes its supply of brushless cream. It is ideally adapted for sale or dispensing in drug stores. hotel lobbies, news stands, vending machines, hotel wash rooms, air line, railroad and bus terminals and club locker rooms. It is also a handy article for travelers to carry to protect themselves from emergency. A supply may also be kept in a private home to care for unexpected visitors.
