1 Claim.

This invention relates to wrappers or envelopes for razor blades. y

Safety razor blades are now packed individually in oiled paper and enclosed in paper envelopes. Practical experience has shown that this method of wrapping razor blades does not prevent the sharp edges thereof from rubbing against the paper wrapping so -that in many instances the sharp edges of a razor blade are dulled even before the user removes the blade from its wrapping Vfor the first time.

In my co-pending patent application, Serial Number 221,296, filed July 26, 1938, I proposed to eliminate this drawback through the provision of an envelope having cushion-lik edge portions enclosing the sharp edges of the ade.

An object of the presen-t invention is to improve a razor blade wrapper of this type by the provision of means preventing any possibility of rubbing or contact between the sharp edges of a razor blade and the wrapper.

Other objects of the present invention will become apparent in the course of the following specification.

The objects of the present inventionmay. be

realized through the provision of a razor blade wrapper having outstanding edge portions extending around the cutting edges of Ithe blade, said Wrapper also having blade holding means extending through the .wrapper and the blade or engaging the blade to maintain it in a position in which its cutting edges will be protected by the outstanding edge portions of the wrapper and will be located at a proper distance from the inner surfaces of these edge portions.

The invention will appear more clearly from the following detailed description when taken in connection with the accompanying drawing showing, by Way of example, preferred embodiments of the inventive idea.

In the drawing:

Figure 1 vis a perspective view of a wrapper enclosing a blade.

Figure 2 shows the wrapper when it is open.

Figure 3 is a section along the line 3-3 of Figure 1.

Figure 4 is a, perspective view of a somewhat different wrapper.

Figure 5 illustrates another wrapper in a perspective view.

Figure 6 shows yet another wrapper in a perspective view.

Figure 7 is a section along 4the line 'I--T of Figure 6.

The envelope I0 shown in Figures 1, 2 and 3 may consist of heavy paper or thin cardboard, or any other suitable material; it comprises a central portion II supporting a blade I2, lateral flaps I3 andl4 and front flaps I5 and I6 which are narrower than the lateral flaps I3 and I4, The outer front flap I6 is provided with a bent tongue II which facilitates the opening of the envelope.

The lateral flap I3 is bent along two lines I8 and I9 in relation to the central surface I I, therebyv forming a thin side wall 20 extending at a distance from the cutting edge 2l of the blade I2. 'I'he lateral flap I4 is similarly bent along two lines 22 and 23 forming a side wall '24 which extends at a distance from the cutting edge 25 of the blade I 2.

As shown in Figure 1, the surfaces of the envelope adjacent'to the side walls 20 and 24 are, preferably, slightlyv bent, so that these surfaces converge in the directions toward the middle of the envelope, thereby forming pockets which enclose the cutting edges 2| and 25 of the blade and the inner surfaces of which surround the cutting edges without contactingthem.

In the folded position of the envelope, the lateral flap I3 extends over the razor blade I2, the lateral apl I4 is placed over the flap I3, the inner front nap I5extends over the ap I4 and transversely thereto, while the outer front flap I6 is placed over the flap I5 and isl provided with a protruding tongue II` to facilitate the opening of the envelope.`

In accordance with the present invention, the blade I2 is held in the proper position Within the envelope vI0 by a clampor clip 26. The clip 26 jprevents the blade from shifting within the envelope and maintains its cutting edge's 2| and 25 in air pockets enclosed by the lateral Walls 20 and 24 and the adjacent surfaces of the envelope. f

Preferably, the clip 26 consists of a piece of bent wire and may be similarto-the clamps, clips or staples used for joining sheets of paper, paper matches and the like. The clip 26 has a front portion 21 extending over the upper flap I6, and two legs 28 and 29 extending at right angles to the portion 21 and passing through openings formed in the upper front flap I 6, the lower front nap I5, the lateral flaps I4 and I3 and through the central opening 30 of the razor blade I2. The diameter of the wire clip 26 is so selected, that its legs 2B and 29 conveniently pass through the central opening 30 of the blade; they may engage the sides of the central opening 30 or they may be smaller than the width of that opening.

edges of the blade from being dulled by contact'- with the surfaces of the envelope. .The blade may be conveniently removed from the envelope, since the iiaps I6, I5, I4 `and I 3 may be easily torn off the clip 26, whereupon the blade 'IZ will 4 be easily disengaged from the clip.

The envelope 40 shown in lFigure 4 is provided with raised portions 4I andx42extending along edges separating the lateral flaps of the envelope. from its central or middle portion which carries' the blade. The folds of the envelope extend substantially through the middle of the raised portions 4| and 42, so that air cushions are formed which completely surround the sharp edges of 4the blade and prevent them from contacting the envelope. Two elongated front flaps or tongues 43 and 44 are situated on opposite sides of the central blade-supporting portion of the envelope and are placed over the lateral flaps of the envelope and one over the other when the envelope is folded. The upper flap 44 is glued to the lower ap 43, and is provided with a bent tongue 45. This constructionvis substantially similar to that described in my .aforesaid patent application.

A razor blade I2 is firmly held in itsproper position within the envelope 40 by two clips. 46 and 4l which embrace the shoulders 48 and 49 of the razor blade.` The clip 46 has a central por-- tion extending over the upper surface of the ap 44 and two inwardly bent legspassing through openings formed in the flap 44 and the lateral fia-ps and on both sides ofthe shoulder 48 of the razor blade. These vlegs extend through the central portion ofthe envelope and are bent `in- .wardly over the outer surface of this central portion. Similarly,the clip 46 extends over the flap 43 and has legs passing throughthis flap 44 and the lateral flaps and on both sides of the shoulder 49 of the blade,y these legs extending through the central portion of Athe envelope and `being bent inwardly over the outer surface of the central portion;

Thus the razor blade is firmly held within the envelope 40 either by direct contact with the legs of the clip 46 and 41, or by pressure exerted by the two clips upon the shoulder portions 48 and 49 of the razor blades.- l

The envelope 59 shown in Figure 5 is substantially similar to the envelope 40 in Figure 4 and includes raised portions 5I and 52 and flaps 53 and 54.A In this construction, a razor blade is AI2 and lateral flaps 62 and 63 which do not overone another.

lap each other, but terminate at a distance from Two raised portions 64 and 65 extend along the edges separating the flaps 62 and 63, respectively, from the middle portion 6I, the fold of the envelope extending substantially I ,through the middle of the raised portions. Two

front naps or tongues 66 and 61 are placed over the adjoining edges of the flaps 62 and 63 when -theenvelope is folded.

The blade I2 is held in place within the envelope 6|] by yflaps 68 and 69 which extend through a central opening 19 formed in the flaps 66 and 61 and the middle portion 6I. The opening 'IIJ is situated above and below the central opening t 30 of the razor blade I2 and may be in alinement with the opening 30. The adjacent edges of the lateral'flaps 62 and 63 are situated on both sides of the opening 10. The flaps 68 -and 69 are integral with or firmly joined to the central portion 6I Vof the envelope; they extend through the opening 'l0 of the envelope and the opening 30 of the razor blade and are bent out- `wardly over, the adjacent edges 0f the flap 61.

Thus the flapst 68 and 69 hold the blade I2 rmly in` itsl required position within the envelope 60. It is apparent that the specific illustrations shown above have been given by way of illustration and not by way of limitation, and that the structures above described are subject to wide variation .and modification without departing from the scope or intent-of the invention, all of which variations and modifications are tobe included within the scope of the present invention.

l What is claimed is:

A razor-blade envelope, comprising a blade- ,supporting portion, naps for covering a blade .carried by said blade-supporting portion and a metal clip having a middle portion extending over the uppermost of vsaid naps, and legs ex tending through openingsr formed in said flaps and said blade-supporting portion and through a `central razor-engaging opening formed in said blade said clip being disposed in its entirety over said central razor-engaging opening, said legs having bent ends extending in opposite directions 'over the outer surface of said blade-supporting portion, whereby said blade is maintained in its position upon said blade-supporting portion.
