UNITED, STATES PATENT? OFFICE Philip A. Derham, Rosemont,.Pa., assignor to 'Armstrong Cork Company, Lancaster, Pa., a l 1 corporationof Pennsylvania Appli ation September 17, 1943, Serial'No. 502,765.

8 Claims This invention relates to asafety' razor case or similar article, particularly adapted for use by members of the armed services and travelers where a lightweight, compact, small-sized, conveniently packed case for carrying a safety razor and blades is desired. l s

An object of this invention is toprovide a case of the sort above referred to in which the handle for the safety razor head is so arranged that it may be selectively utilized for its normal purpose and may also serve to securethe elements of the case against accidentalseparation. Another. ob-.

ject is to provide a case so constructed :and ar.-:

ranged that it may be substantially completely formed oflightweight molded plastic parts of sufficient rigidity for general use and willwithstand rough handling. A further object is to provide a case in .which the safety razor head and blades will be immediately availablefor grasping by the user when the cover is removed from the case without the necessity of inverting the case with the possibility of' dropping the blades or the head or both;

The case proper is formed with a 'compartmental base and a cover portion. The base is preferably formed with three compartments, 'one to receive a safety razor head, another to receive safety razor blades, and '-a third to .ireceivei a safety razor handle. Complementary engaging means, such as a rabbetedijoint'are provided on the base andcoverportionstto alignthem. :The'.

parts aresecured asa unit against separation by the safetyrazor handle whichpasses through anopening in the cover and into the handlecom partment. A screw threaded projectionor its equivalent, is provided in the base to receive the threaded end of the handle. Thus, the cover and basemay be drawn firmly together and all possibility of accidental separationof the partsis eliminated. The same handleserves as a handle for the safety razor when the unit is opened and the razor head withdrawn andv a blade inserted for use, The handle compartment is preferably so constructed that it serves to guide the handle into the proper alignment with the screw thread ed projection in the base andthus ,facilitates assembly and locking of the unit.

In order that the inyention may be morereadilyunderstood, I will describ'ethe same in con: nectionwith the attacheddrawing in which Figure lis a view partially in section and pare, tielly in ev ti n h w nsapreferr em qdis msnt q my int t .a.= s

Figure 2 is a top plan View showing the base tion removed;

Figure 3 i a front elevation of the case in assembled, closed position; and 7 Figure 4 is a side'elevation thereof.

The case comprises a base 2 and a cover 3, each being generally rectangular in horizontal cross section as shown inFigure .2. The base and cover portions are 'interfitted'at 4 so as to properly align both sections in assembled position. In the embodiment illustrated, this interfitting is accomplished'by means of-a so-called rabbeted joint, but other equivalent arrangements may be provided. v

The base 2 is provided with a compartment 5 which receives the head 6 of a safety razor. "A recess I, defined by a pair of ribs 8 and 9, receives the s'crew threaded' portion of the razor head'fi and limits lateral movement in'the case.- A pair 0 of ribs l0 and. H serves to-limit-downward movement of the razor head to provide that the razor head will projectslightly thereabove when the cover is removed so that the razor'head may be takenfrom the base conveniently.

5 The base 2 is also provided with a compartment I2 which receives a package of razor blades [3, or loose or wrapped'blades,if"desired. Ribs I4 and I5 are provided in the bottom 'of the base 2 to support the package of blades [3 in upright position, slightly above the-top ,of the base! when the cover is removed from the case for convenient grasp.

A third compartment I6 isprovid'ed inthe base 2 and this receives a safety razor handle II with a reasonably close fit. This is best illustrated in Figure 1, where thepartitionwalls l8 and I9 of the compartment ["6 are shown in'clo'se proximity to the safety razor handle ll. Ribs 20 and 2| (Figure 2) are provided onthe walls of the base opposite the partition walls and these ribs, in cooperationwith the partition walls l8 and I9, serve to guide the handle ll into positionfor engagement with/a projection in the formof a screw threaded metal insert 22 which, as illustrated in Figure '1, may be molded into'the base portion 2. The screw threaded formation 23 on the metal insert 22 is complemental to the thread formation on the handle [1. In place of screw threads, other complementary engaging means may be provided on the handle and insert. The safetyv razor h'ead, 6 is'providedjwith a screw thread projection25 which receivesjthe handle "when the razor is in use, the threadfor- $5 mation 24 on the handle I! being complemental to the handle engaging projections on both the razor head and the base of the case.

The cover portion 3 is provided with a downwardly projecting rib 26 which is elfective for limiting substantial upward longitudinal movement of the safety razor head 6 when the unit isassembled. A similar rib 21 is provided for limiting movement of the package of razor blades The cover 3 is provided with an openingZB of a size which conveniently passes the shank of the safety razor handle I! and an enlarged head 29 is provided on the handle IT which en-. gages the Wall of the cover surrounding the opening 28 to press the cover down onto the base.

In assembly of the unit, the cover 3 is placed on the base 2 with the rabbeted joint 4 in alignment. The handle I 7 is then inserted through the opening 28 into the compartment l6, being guided therein by the partition Walls l8 and f9 andthe ribs Ml and 2 I-. When the screw threaded end 24 of the handle [1 comes into engagement with the: screw threaded metal insert. 22, rotation is imparted to the handle I] by the user grasping the head 29.. The base. and cover portions are thus locked together against accidental separation.

In use of the case; the handle I! is unscrewed andremoved, the cover is removed and the razor head 6 is taken from the case. A. blade; is removed, and: inserted and the handle H is then screwed onto the projection 25 or the safety razor head and the razor is ready for use,

The entire case, with the exception of the metal insert 22 in the. base; may be formed by molding any of the well-known, compositions, such as Bakelite or the like. It will. be observed that the walls of the container are relatively thin and light and this is made possible primarily by reasonv of the provision of the partition. walls l8 and IS, the ribs. 8., 9, M1,. and H in the base and the ribs 26 and- Z'l in th e cover. These all serve to reinforce the. side walls of the base. and cover and prevent. mold warpage. even with such thin wall sections, The handle IT. is selectively engageable with thein'sert 22 to hold the base and cover in. locked engagement'and with the safety razor head when-used for shaving. The unit; will Withstand. rough. handling which might be encountered in travelling and by members. of the armed services, in combat dutyl The unit is small, and may be conveniently packed into a small. space as in the pack of a soldier and there is no possi ility of theparts becoming separated or the razor. head or biad'es becoming scattered throughout the duffel which might result in damage'or injury to the person or clothing of the user;

While the handleis' shown in the embodiment illustrated as extending through the cover and into engagement with a projection inthe base, it isobvious that the handle may be fitted into the base and received into a. projection in the: cover. Also, instead of having the screw threaded proiectionon the; base: and; safety razor head, the projectiongmiay be.- provided on the. handle andbe selectively engageable with a threaded recess in the head and base. In place of screw threads, a bayonet joint or other suitable interengaging means may be provided. Other changes may be made to suit the taste of the designer, for the invention is not limited, to the embodimerit, shown but maybe otherwise embodied. and practiced within the scope of the following claims,
