GILLETTE SAFETY RAZOR COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OI DELAWARE Application filed 'July 8, 1928. Serial No. 290,214.

An object of my invention is to provide a package of razor blades, in which the blades may be retained in a stack in a casing and may be discharged successively without requiring the blades to be handled until discharged. 7

Another object is to provide means for guiding the blades within the casing in such a way that the sharpened edges of the blades will be kept from contact with the casing,

so as not to dull the blade edges while within or while bein discharged from the casing.

A further ob ect is to provide means for guiding the blades while being discharged in such a way that the sharpened edges of the blades will be kept from contact with the sides of the casing or its discharge opening by the action of the ejector.

In carrying out my invention I provide a go casing adapted to retain a stack of blades therein, said casing having an outlet slot for delivery of the blades, an ejector slidably carried by the casing to engage, the endmost blade of the stack to eject it, guiding means 5 within the casing for .the blades to keep their edges from engagement with the casing, and means to keep the bladessnugged within the casing in position to be ejected successively. My invention also com rises novel details so of improvement that willbe more fully hereinafter set forth and then pointed out in the claims.

Similar numerals of reference indicate corresponding parts in the several views.

The numeral 1 indicates a hollow casing adapted to contain a stack of razor blades 2. Said casing may be made of a single piece of metal drawn to shape and provided with an opening at one end to be closed by an endv wall 3 that maybe folded to closed position (Figs. 3 and 9) after the blades and other parts have been inserted within the casing. A discharge opening or slot for the blades is indicated at 4, which may be provided by making the end wall 3 of suitablewidth so that when said wall is folded to place the opening or slot 4 will be provided. The marginal portions of the outermost blade of the stack are adapted to bear against the v outer or top wall 5 of the casing, and the stack of blades is kept pressed toward said wall by springs or bottom wall 7 of the casing. The springs 6 are shown struck out from a metal plate 8 within the casing. In the form shown in Figs. 1 to 5 the plate 8 bears against the wall 7 and the springs bear against the adjacent blade of the stack, whereas in Figs. 7 to 10 the springs 6 bear against the wall 7 and the plate 8 bearsagainst the adjacent blade of the stack, to keep the blades pressed toward wall 5.

In Figs. 1 to 5 projections or posts 9 pass through openings 20 in all the blades except the endmos t blade adjacent to the wall 5 6 which oppose the opposite contact with the adjacent side walls of the casing. The projections 9 are shorter than the depth of the casing so that the outermost blade of the stack will be free from'the projections to slide through the outlet opening. The projections 9 are shown formed on the plate 8, which may be done'by bending parts of said plate laterally from said plate. The projections 9 are shown so located as to engage the outer side walls 2 of the openings 2a of the blades, (Figs. 2 and 3), and since said walls are shown curved the guiding projections 9 are shown correspondingly curved.

In the form shown in Figs. 7 to 10, in which blades having single cutting edges are shown, the heels or back edges 2" of the blades engage the side wall 10 of easing 1, and the corners. of the blades, at the ends of the. cutting edges, engage angularly disposed corners 11 of the casing, whereby the blades are guided with their cutting edges out of contact with the casing.

In order to permit the outermost blade of the stack to be ejected from casing 1, to avoid 1 danger of the users fingers engaging the cutjections 9, and so on each time the ting'edges of the blade, I provide an ejector 12 that is slidable along the wall 5 against the outermost blade of the stack, which ejector is provided with a resilient projection 12a that is adapted to enter one of the openings 2a or 2?; of the blade to push the latter through the discharge opening 4 of the casing. The ejector is shown slidably guided in a guiding recess or groove 13 (Figs. 4 and 8), which may be formed by pressing out the metal of wall 5 of the casing. Said pressed out portion of wall 5 is shown provided with a longitudinal slot 14 through which a projecting finger-piece 12 extends from the ejector in position to be engaged by the users finger to slide the ejector back and forth. When the ejector of Figs. 1 to 5 is moved to the right in Fig. 3 the outermost blade of the stack will be pushed through the discharge opening 4 of the casing in such a position as to be engaged by the fingers to pull the blade out of the casing, (Fig. 1), and the projections 9 will retain the other blades of the stack from sliding. When the ejector has been-pushed back (to the left hand side of Fig. 3) the springs 6 will push the stack of blades toward wall 5 for engagement of the ejector with the outermost blade, the latter being released from proejector is slid back and forth. In the form shown in Figs. 7 to 10 the heels of the blades and their cutting-edge corners retain the blades of the stack from displacement while the outermost blade is being ejected and while the ejector is pushed to the left in Fig. 9. In the form shown in Figs. 1 to 6 the heel 12a of the ejector 12 operates on blade 2 by enteringblade opening 2a and pushi g against the extreme ends of its wall 20, thus keeping the outermost blade inalignment while being ejected, and also serving to retain the edges of the outermost blade, that is free from the projections 9, from engaging the casing while said blade is retained in the casing, so that its cutting edges will not engage the casing. In the form shown in Figs. 7 to 11 the heel 12a of ejector 12 enters opening 26 of blade 2 (Fig. 11) and thus keeps the alignment of the blade between said ejector heel, the heel 2 of the blade and the wall 10 of the casing, (Fig. 7 and 8), while said blade is being discharged so that its cutting edgewill not engage the casing.

In accordance with my invention I provide a package of blades in which the blade edges are protected so as to avoid danger to the users'fingers in obtaining a blade from the casing, or in handling or transportation of the package, and in which the blades need not be wrapped in paper or placed in envelopes separately, as has been the custom with safety razor blades. My improved blade pacakge may be made cheaply so that the casing may be discarded when all of the blades have been ejected therefrom.

Changes may be made in the details set forth without departing from'the spirit of the appended claims.
