4 Claims. (Cl..3-47) .This invention relates to .a collapsible razorl andfmore particularly'to acollapsible razor wherein the razorfwhen.
notzlnuoperating position is housed in a cover, approximately'the. same s1ze as a paper match box cover, but
iszadapted tobeexpanded to the normal razor size. In.
addition,.the.razor is constructed of such a .material and inasuch a manner that it may readily. be disposed of` without .any measurable. financial loss.
There often arises instances wherein men find themselveszina situation where it is imperative that they have animmediate shave, but find to their dismay` that there. iszno barbar shop open or available or that they` have 11o razor with which to shave themselves. With the standard razors presently available on the market, it is` notpractical to purchase anew one 1n such a sltuation: and isince you cannot always foresee when th1s calamity-v .It is therefore a primary object of this invention toprovide an inexpensive and economical collapsible razor.
It is a further object of this invention to provide a collapsible razor that may be housed in a small compact housing when not in use, but which may be expanded when in use so as to conform with a standard razorssize, shape and form.
It is an additional object of this invention to provide aninexpensive and economical collapsible. razor so that it may be disposed of after being used one or more times Without being prohibitive in cost. A still further object of`this.invention is to provide a means of constructing a collapsible razor out of-paper' or cardboard so that it may readily be disposed of after a single use.
Anr additional object of this invention is to provide a collapsible razor that may be simply and readily expandedlinto'a normal razors-Ysize, shape and-form.
Other and-more specific objects and advantageswill become apparent from the following detailed description, when read in conjunction with the accompanying drawings which illustrate a collapsible razor in accordance with one embodiment of this invention. It should be understood, however, that this invention is not limited to any particular form, but that various changes may be made in details, but within the scope of the appended claims without departing from the spirit of this invention.

v.Figure 7 is another; embodiment .ofthe :razor head 'employedin:thefconstructionof the collapsible razor.
:Referring to'thevdrawings, there isshownin Figuressla, through 1d, the collapsible razor 1l. disassembled and completelyincased in thehousing 12.' In this position the: razor is approximately two (2) inches by oneand one-half (11%) inches` and'has the general appearance of afstandard closed paper match cover. The cover for the :housing 12umay. be constructed of a single: sheet of water-'repellent paper, cardboardj orV other suitable materialland for. purposes ofl illustration only, applicant will describe one "embodiment constructed out `of a single sheetl of water-repellent paper 14 of approximately four and-.one-half (4l/2') inches in-length and one and onehalf (l1/2.) inches in width. It should bey noted that the'dimensions are only given for purposes of describing a preferred embodiment of applicants invention; but in no fway is meant to limit applicants invention.
'Ille'inside cover'15 of housing 12 is scoredin various areas tofacilitatethe-assembling of the razor as willbe hereinafter more fully described. Running the lengthv of: theinside .coverl are twofslightly divergingscored` lines 16 as shown in Figures 2 and 4. Transversingfthe. inside.r cover 15, are two'parallel scored lines.17. rlfhe purpose .of whichwill be describedin detail infra. Referringt to Figure. l'b there isv shown: a third transverse' scored line 18 whichjoins with two thirty degree (30) diagonalv cuts 19 ini the cover 1S. One. edge 21 of the: housinglZ isbent tofform a'ap 22 which is usedto house the razor head 31, both of which willbe. more fully described below.
Therazor head 31 isconstructed of a razor guard32, constructed.ofanysuitable material such as plastic. and, a razor `blade.33. Both the razor blade 33 and'guard S12-arek mounted-in a base 34 which in turn is incasedv andhoused in an areaformed by bending flap 22, las shown in vFigure 3. The entire razor head is then secured in position'by any suitable means such as a staple 36, shown in Figures la and 1b and Figures 2 and 4.
.In Figure 7 there is shown another embodiment of razor head31 which shows the razor guard 32 andbase 34 Vconstructed `of a single piece of material such as plastic. withtherazor blade 33 mounted therein. This is merely a variationthat may beemployed in the construction l of r the 'razor head.
Mountedon the Ainside-cover 15 of housing 12iis shaving soap `41secured thereto by any vsuitable gluing agent. Itlshould be noted thatthe shaving soap is so shaped and positioned so as to lit within the area defined by scoring lines 1'6 and 17. If desired, an aseptc pencil may be mountedin the upper area defined by scored line -16 and 17, although the same is notshown in the drawings. The scoring on the inside cover 15 serves the following purposes: The transverse scoring 17 permit the cover for the housing 12 to form the top of the housing 34 as shown in Figure 1c. The diagonally divergng scoring 16 permits flaps 44 to be bent to their desired position as shown in Figure 4 and which will be more fully described hereinafter. The third transverse scoring 18 together with the 33 degree angle cuts 19 permit the razor head 31 to be positioned at the required thirty degree (30) angle as shown in Figure 5 and which will be more fully described below.
On the rear cover there are two vertical cuts 46, the area surrounded by the cuts 46 is reinforced by a suitable metallic strip such as a thin gage aluminum strip 47, one end of which is secured to the inside cover 15 of the housing 12 at point 48; the other end of strip 47 is mounted under the staple 36 as shown in Figures 2, 4, 5 and 6. The purpose of the cuts 46 and aluminum strip 47 is to brace the razor head 31 when in operating position and to further act as a stop when in said position as shown in Figures 5 and 6. When in said position, the end of the aluminum strip 47 mounted under the staple 36 is extended beyond said staple and bent as is at 49 so as to act as a lock as shown in Figure 5.
The procedure in assembling and operating the collapsible disposable razor is as follows: As shown in Figures 1a through ld, the razor is disassembled and housed in cover 12, when in such a position the razor gives the appearance of a paper match book cover as it is approximately the same size. In such a position the razor is easily and safely portable without any danger of receiving any cuts from an exposed razor blade since the same is completely incased in housing 12. To assemble the razor, one end of cover 15 is extended, as shown in Figure 2, flaps 44 are then bent along the diagonally diverging scored line 16 and turned toward the rear as shown in Figure 4. The two thirty degree (30) angle diagonal cuts 19 permit the flaps 44 to be bent at ninety degree (90) angles to the central portions S1 of the inside cover 1S without any buckling at said points.
The razor head 31 is then bent at a sixty degree (60) angle from the vertical position as shown in Figure 5. The ends of flaps 44 provide a support for the razor head 32 when so positioned. The aluminum strip 47 is then adjusted as shown in Figure to further support the razor head and is then bent at 49 to lock the razor head in operating position. When the above steps have been followed, the razor is then assembled and ready for use. The soap 41 may be removed and used to lather the face. The razor is constructed of such a material that it would be practical to dispose of the same after a single use.
From the foregoing, it will be evident that a collapsible razor constructed in accordance with this invention provides many advantages over conventional standard razor; is simple in construction, practical, inexpensive and highly efficient.
