comma.

This invention relates to the packaging for distribution of safety razor blades and consists in a novel package of blades securely protected against becoming dulled or rusted up to the time 6 that they are actually presented to the razor by the user. The invention includes within its scope the novel protected blade herein shown as one component part of the package of my invention.

In handling safety razor blades under commer- 10 cial conditions of distribution and in the more or less casual handling by the user the extremely fine keen edge of the blade is likely to become dulled by being brought into contact with its wrapping or other objects before the blade can be actually clamped in its shaving position in the razor. On this account the best and most skillful efforts of the manufacturer in sharpening blades are often brought to naught because of the difficulty of preserving intact the very fragile and delicate structure of a blade edge which has been brought ta the keenest possible shaving condition.

With these conditions in view an important object of the present invention is to provide a novel package of protected blades in which each blade is enclosed between cover sheets projecting outside its cutting edge and protecting it from direct contact until such time as the blade has actually been presented in its shaving position in the safety razor by the user.

I have discovered that such a protective cover may be made to adhere to one or both surfaces of a safety razor blade in a clinging or slipping manner of engagement so that it may be readily removed by being drawn or slipped off the blade. Preferably and as herein shown each blade is provided with a protective cover sheet secured to its opposite surfaces in edge-free manner, that is to say, with the edges of the sheets in registration with each other but not attached to each other opposite to the cutting edges of the blade. The cover sheets thus employed to protect the blades are then bound together or fastened at one end in book form, each book or package comprising flve or six or more protected blades.

The package of my invention is particularly adapted for thin flexible blades internally apertured to receive the blade-positioning projections of a safety razor. The protective cover sheets are accordingly longitudinally slotted in registration with the apertures of the blade which they enclose. Each of the leaves, moreover, may be transversely scored or otherwise weakened so that it may be readily torn out of. the book by the user and in accordance with another feature of my invention the weakened line of each leaf is so located as to intersect the slot therein and preferably at a point adjacent to or coincide with the inner edge of the slot, that is the edge of the slot nearest the binding of the package. An advantage of this construction is that when a leaf is torn from the package on the scored line only one end of the slot in the leaf is opened. In other words, the protective cover sheet which may be originally rectangular in form and some,- what longer than the blade is, by tearing off the sheet, converted into a U-shaped configuration. It follows, therefore, that the blade thus protected may be placed by the user in his safety razor with the blade-locating projections thereof extending into the aperture of the blade. The dimensions of the slot in the cover sheet, however, are such as to clear the blade-locating projections so that the cover sheet is free to be drawn ofl from the blade in edgewise direction while the latter is held positively in place in the razor. It will be noted that the sharp edges of the blade have been protected until after the blade has been presented in its final location and is no longer liable to be damaged by contacting with its wrapping or with any part of the razor to the serious detriment of its keenness. After the protected blade has been so located the cover sheets may be withdrawn easily and with no tendency whatever to pass across or dull the cutting edges of the blade.

These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof, selected for purposes of illustration and shown in the accompanying drawing, in which- Fig. 1 is a view in perspective of the blade package, showing its outer cover in raised position;

Fig. 2 is a view in perspective of a blade-containing leaf of the package as it appears when torn from the package;

Fig. 3 is a view in perspective .of a razor for use with the blade shown in Fig. 2 is designed;

Fig. 4 is a similar view showing a blade in position in the razor and its protective covering partially withdrawn; and

Fig. 5 is a modified form of blade package.

It will be understood that my invention is in no sense limited for use in connection with any specific type of safety razor blade, and that the r particular blade shown represents merely one safety razor blade of well-known commercial type. The blade I 0 is of thin flexible steel, sharpened at its opposite edges for cutting and having corner recesses defining an elongated centrallythrough its free ends.

disposed unsharpened portion. The blade is internally apertured. being provided with a long slot l2 having spaced enlargements of characteristic outline in its length and being designed to register with and fit upon the blade-locating projections of the razor in which it is to be used.

As shown in Figs. 1 and 2, each blade is en-: closed and protected in a leaf 14, each leaf comprises two sheets of thin waxed paper or the like of the proper size and shape completely to envelop the blade and to extend in edgewise relation slightly beyond the cutting edges thereof, so as to act as a guard or fender therefor. The

sheets of each leaf, moreover, extend longitudinally a substantial distance beyond the ends of the blade and are maintained temporarily attached thereto in slipping engagement by spots I! of vaseline or the like. The sheets of each leaf are provided with a longitudinal slot l6 registeringwith the slot of the enclosed blade and preferably being slightly wider so as to clear the blade-locating projections of the safety razor when the protected blade is presented thereto.

The individual leaves, each with its enclosed blade, are bound into hook form and held to: gether by the staple fastener 20 which, as shown in Fig. l, is inserted through one end of the stack, and assembled with the blade-containing leaves is an outer cover 22 of pasteboard or the like upon which advertising matter may be advantageously displayed. The cover 22 may comprise a single piece of cardboard folded upon itself and stapled Its outer folded end '23 is scored or perforated so that it may be torn off by the user in unsealing the package.

Each leaf is made of a single strip folded upon itself and is weakened in a definite location as by being provided with a transverse scored line "I which intersects the slot [6. As herein shown the scored line l8 coincides substantially with the inner edge of the slot It. This facilitates the removal of any individual leaf from the book by tearing, leaving the stub end of the leaf secured in the back of the book-like package. It will be noted that since the location of the scored line I8 is such as to intersect the slot, the effect of tearing out one of the leaves is to open the inner end of the slot 16 and convert the leaf from rectangular to U-shaped configuration.

Fig. 7 represents the package as unsealed by the removalof the end 23 and Fig. 2 represents a leaf torn from the package,.the scored line l8 defining the ends of the side portions of the U-shaped cover. In this condition the two sheets of the cover are maintained temporarily or yieldingly in place by spots of Vaseline I! or otherwise. The two sheets of the leaf are separate and unconnected at their longitudinal edges and joined by a fold at one end.

In Figs. 3 and 4 is shown one type of safety razor particularly adapted to receive a protected blade of the character herein disclosed. This.

razor is the subject matter of my co-pending application Serial No. 683,356 filed August 2, 1933, to which reference may be had for further details of construction, Briefly stated the razor comprises a guard 24' or blade-supporting member and cap sections 26 pivotally'mounted upon the guard, cooperating therewith to flex the blade and maintain it clamped for shaving in a condition of transverse curvature. The bladelocating projection of the razor in this case comprises a longitudinal rib 28 and upon this the slot l2 of the blade is adapted to fit and so maintain the blade accurately in proper position as to its edge exposure for shaving. The razor is provided with a handle 30 and .with operating meohanism not herein shown for swinging the cap sections to and from blade clamping position.

In presenting a protected blade to the razor shown in Figs. 3 and 4 the user has only to place the blade upon the guard 24 in the usual manner without regard to the protective cover thereof, whereupon the rib 28 enters the slot l2 and becomes effective to locate the blade and also to hold it against displacement in the razor. The blade may be thus presented either end about as best suited to the convenience of the user. Having thus located the blade the user has only to grasp the projecting end or tab of the cover l4, and slip it endwise from the blade I0, as suggested in Fig. 4. The adhesive spots ll do not interfere with this operation but permit the cover to be conveniently withdrawn leaving the blade fully exposedand accurately located in shaving position and without any possibility of objectionable contact having been made with its cutting edges. Upon closing the cap sections 26 the assembled razor is ready for use. Meanwhile the remaining blades are retained safety in the package ready for removal and use as desired.

In Fig. 5 is shown an alternate form of package similar to that above described except that the protective covers 34 are formed with openended slots 36. As herein shown they are bound together by a staple fastener 38 in covers 40. In using this form of package there is no necessity for tearing out the respective leaves. Each leaf may be presented to the safety razor and the blade Ill located upon the guard 24 in registration with the rib 28 and then the cover 34 removed from the blade by drawing the leaf and package away from it in an endwise direction while the blade is so held.

While the package is herein shown as bound or fastened by a staple 20 it will be apparent that any other suitable fastener may be employed, such for example as an eyelet or tubular rivet.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is,-

1. A package of protected safety razor blades, comprising a series of double leaves of sheet material connected at one end, each leaf enclosing the ends and edges of an internally apertured blade, being slotted to clear the blade-locating projections of a safety razor and scored so that it may be torn oif on a line intersecting the slot therein.

2. A package of protected safety razor blades, comprising a plurality of leaves connected at one end and each enclosing an internally apertured blade, each leaf being longitudinally slotted in registration with the aperture of the blade and transversely weakened across one end of its slot, whereby the slot is opened when the leaf is torn from the package.

3. A package of protected safety razor blades, comprising a plurality of leaves connected at one end in book form and scored transversely, each leaf enclosing an internally apertured blade and extending outwardly beyond the end of the blade and being also longitudinally slotted to clear the blade-locating projections of a safety razor, the scoring of each leaf intersecting the slot in the 4. A package of protected safety razor blades, comprising a plurality of leaves in book form temporarily attached in edge-free condition to the opposite faces of an internally apertured blade, the leaves being longitudinally slotted to clear the blade-locating projections of a safety razor and transversely scored on a line so located as to open the slot in the leaves when they are detached with an enclosed blade.

5. A package of protected safety razor blades, comprising a book of leaves attached temporarily in edge-free condition to the opposite surfaces of interleaved double edged razor blades and extending beyond the cutting edges and beyond both ends thereof, said blades being internally apertured and eachleaf being slotted in an area to clear the blade-locating projections of the razor and scored in a manner to present an open-ended slot when separated from the package.

6. A protected double edged blade internally apertured for engagement with the locating projections of a safety razor and having edge-free w anwnz lza e15, We.

cover sheets securedto its opposite faces by an adhesive, the cover sheets being slotted to clear the projections of the razor, being initially rectangular in outline and scored transversely in a location whereby they may be converted to U-shaped configuration by tearing.

7. A protected double edged blade having a long internal slot for engagement with the bladelocating rib of a safety razor and having rectangular cover sheets attached to its opposite faces by an adhesive, the coversheets having a longitudinal slot of such dimensions as to clear the blade-locating projections of the razor and a transverse score line upon which the cover sheets may be parted to open the end of the slot outside the end of the blade thereby leaving only the end portion of the blade bridging across the slot ofthe cover.
