Abstract: 694,361. Package; cases for razor blades. GILLETTE SAFETY RAZOR CO. Dec. 16, 1949, No. 32378/49. Classes 18 and 94(i) An assemblage of bare razor blades has the blades mounted on a carrier in,substantial longitudinal alignment with each blade above the lowermost blade overlapping the immediately underlying blade and with one end only of each of the blades so detachably secured to the carrier that the blades may be readily successively removed from the assemblage. The reduced ends 19, Figs. 1, 2, of unwrapped razor blades 18 are inserted through longitudinally spaced transverse slits 12, cut in a carrier 10 which is of a width greater than that of the blades, so that the blades lie in staggered longitudinally overlapping relationship. The inserted ends 19 are secured by a non-drying adhesive 14 to the underside of the carrier 10 and a transparent cover is stuck by a non-drying adhesive to the topside margin of the carrier so as to cover the blades. Transverse scored fold lines 16 are formed on the carrier 10 in line with the slits 12 to aid removal of a blade. The carrier and blades may be inserted in an open-ended envelope. In another embodiment of the invention. Fig. 15, blades 30 are stuck together at one end in longitudinally overlapping relationship and are secured by a non- drying adhesive 36 at the same end to a cardboard or paper carrier 34. The carrier and blades are inserted in an envelope 60 closed at one end and formed with spaced inwardly directed tabs 52 at the other, open, end adapted to engage a tab 40 on the carrier 34 to prevent complete extraction of the carrier. In another embodiment, Fig. 16, a boxlike carrier 72 of rigid material, open at the top and one end, has its closed end 74 formed with stepped blade-receiving recesses 75 into which the reduced ends of blades 76 are inserted. A depression 78 in the bottom of the carrier contains a non-drying adhesive 80 which secures half the bottom blade and the ends of the other blades to the carrier. A groove 82 in the carrier base facilitates withdrawal of the blades. A transparent cover strip 84 is secured over the top of the carrier by a non-drying adhesive. In a further embodiment, Fig. 18, the reduced ends of blades 104 are inserted through slots 98 in a carrier 90 and secured by a non-drying adhesive to the back thereof. A backing strip secured to the back of the carrier 90 covers the reduced ends of the blades and may be stuck to them. The carrier is folded on a hinge line 109 and a tongue 92 at one end inserted in a slot 110 at the other end to close the package. In a further arrangement, Fig. 22, the inserted ends 128 of the blades are held in position by a backing strip secured to the side margins of the carrier, and a transparent cover on the top of the carrier completes the package. In a further embodiment, Figs. 25, 28, the reduced ends of the razor blades are inserted through slots 142 in a carrier 140 and tongues 141 cut from the carrier inserted through slots in the blades. The blades are then bent back on the carrier through 180 degrees and held in this flexed position by a sheath 152, Fig. 28. In a further embodiment the tongues and slots are formed as at 232 in Fig. 35 and blades on such a carrier are placed in a metal box 266, Figs. 39, 41, formed with side flanges 273 and end tabs 270, 272 and having a sliding cover plate 274. Specification 694,093 is referred to as describing a razor which may be used to disengage a blade from its assemblage.
