a 9 Claims. (01. 206-16) This invention consists in an improved package or magazine for safety razor blades or other fine edged blades. Itv may be used, if desired,

for dispensing blades in sale to the'public, to i keep a reserve supply of blades in fully protected condition and to deliver them one by one as required for use in a safety razor or other holder.

The general object of my invention is to improve packages or magazines of this type in respect to security of the product and convenience and safety of the user. It is important that a magazine should be capable of being easily filled by the manufacturer, by automatic machinery if desired, and that the blades in the magazine should be maintained with their sharp edges out of contact with all parts thereof, not only while in the magazine but when being withdrawn therefrom. If this is not done reliably the skill and care of the manufacturer in producing exceedingly fine keen cutting edges in his blades goes for naught because the slightest contact in withdrawing the blade from the magazine is likely to disturb the delicate structure of the blade edge. All these conditions are met in the package or magazine of my invention. It is provided internally with positive means for locating the stack of blades out of contact with the walls of the magazine and in line with the delivery opening. The interior of the magazine and its internal blade-locating means are fully exposed when the top or inner casing is removed, and when the magazine has been filled the two may be securely attached without in any way disturbing the blade stack.

An important feature of the invention consists in a telescopic cap or cover having, first, the function of completely closing and sealing the magazine so that the blades are completely protected from moisture and, second, the function of partially withdrawing a blade from the stack in the magazine when the cap is removed. This is accomplished as herein shown by providing the cap with an internal tooth or detent which is arranged to engage an aperture in the uppermost blade of the stack through a slot provided for that purpose in the inner casing of the magazine. Accordingly, when the cap is removed the uppermost blade in the stack is drawn after it either completely from the magazine or sufficiently to permit the user to grasp it without any danger of cutting himself.

It is important in blade packages or magazines having a narrow outlet slot to prevent positively the danger of two blades being jammed at the same time in the slot. This undesirable occurrence is positively prevented in the magazine of my invention by providing a blade depressing rib in the top of the magazine leading toward the delivery slot. When a slotted blade is drawn forwardly, and advanced through the outlet slot, its solid end portion will encounter the bladedepressing rib. The blade itself will, therefore, be depressed as its solid end passes along the rib and all the blades beneath it will be correspondingly depressed and thus carried positively below the exit slot.

Accordingly, another feature consists in a pair of blade-locating ribs arranged within the enclo sure of the magazinein" opposed relation upon the top and bottom of the enclosure and spaced slightly from each other and having mating sinuous contours. The blade stack is registered upon the lower rib except for the'uppermost blade thereof which is pushed upwardly by the stack and a spring beneath' the stack upon the uppermost rib. When that blade is ejected its solid rear end follows the sinuous contour of the upper rib and depresses all the blades below as above explained.

An optional but very attractive feature of the casing employed in the magazine of my invention is that it may be transparent so that at a glance the user can determine how many unused blades he has in reserve. Accordingly, I prefer to employ Vinylite or other transparent synthetic resin for the entire magazine or at least for sufficient of it to expose fully to view the blades contained therein.

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 drawings, in

The magazine herein shown comprises inner and outer casing members It and ii of transparent material which, in the finished magazine. are fitted together with transparent cement and form an integral rectangular enclosure. The outer casing, as shown in Fig. 10, comprises side walls and a fiat bottom II which extends forwardly beyond the ends of the side walls, the latter terminating in inclined edges. At its forward end the bottom I I carries an upstanding outwardly concave wall II, the upper edge of which constitutes the lower edge of the delivery slot of the magazine. The outer casing is also provided with a straight upstanding blade-locating rib i3 extending symmetrically between the side walls of ihe casing and spaced at its ends from both the rq-ar and the front concave wall of the casing. The upper edge of the rib I3 is straight and parallel to the bottom of the casing for little less than half its length while the forward part of its edge is concaved in a long smooth slope giving a sinuous contour to the edge as a whole.

The inner casing, as best shown in Fig. 9, is also rectangular in shape and includes side walls spaced to fit snugly within the side walls of the outer casing l and a rear wall. Its top wall l6 terminates in a concave front edge corresponding in curvature to the curvature of the concave wall I! of the inner casing. The top It of the outer casing is provided with a central longitudinal slot i! which extends inwardly for about one-half an inch from the concave front edge of the top. To the rear of the slot l1 and in alignment therewith is provided an internal depending blade-depressing rib i8 having a lower convex edge which corresponds in curvature to or mates substantially with the sinuous edge of the blade-locating rib I3 already referred to. The two rib are arranged in vertical alignment and spaced from each other by a slit that pennits the passage of a single blade with clearance between them. The rear wall of the inner casing is provided with a pair of spaced vertical ribs l9 which are arranged to engage corresponding notches formed in the corners of the blade. It will be seen that the outer casing member III has no top and the inner casing member I has no bottom. The package is completed by assem bling the two casing members as shown in Figs. 1, 3, 5 and 8 and cementing them together. Where the Package is used to dispense blades by the manufacturer to the public a stack of blades to the number of eight or ten or more may be inserted by automatic machinery'before the two casings are cemented together.

Within the complete casing is provided a leaf spring 2i best shown in Fig. 12. This is rectangular in outline and of sufilcient length and.

width to fit with clearance within the casing. It is longitudinally slotted in its main body portion at 22 to receive a blade-locating rib l3. Its ends are inturned beneath the body of the'spring and these too are slotted at 23 to receive the rib IS.

The spring may be made of Vinylite or other. vtransparent resilient plastic material or it may bemade of metal, if preferred. If it is transparent the stack of blades within the enclosure may be inspected from either the top or. bottom of the package.

The package is closed by a rectangular cap 2| best shown in Fig. 11. This is designed to telescope upon the end of the magazine having the delivery slot therein. It is herein shown as having the same width as the outer casing Ill and side walls having edges inclined to correspond to the end edges of the side wall of the outer casing II. It is of sufiicient depth to receive freely the end of the complete casing having the concave wall l2. Its upper wall is provided internally with a downwardly extending tooth or detent 18 designed to pass freely through the slot II in the top wall It of the inner casing and to engage the outer end of the slot in the uppermost blade 2| of the stack. The tooth 2B is forwardly bevelled and consequently when the cap is closed it will slightly depress the uppermost blade of the stack against compression of the spring 22 and snap into the end of the blade slot when fully in place as shown in Fig. 5. When the cap is removed, however, the tooth 26 draws the uppermost blade forwardly out through the blade exit slot to some such position as is indicated in Fig. 8 in which the end of the blade is fully exposed so that it may be conveniently grasped by the user and drawn entirely out of the magazine.

The magazine is herein shown as, containing a stack of five double-edged blades N of well-- known commercial type each provided with a central longitudinal'slot and having reentrant notches formed in its four corners thereby defining solid elongated unsharpened end portions. As the blade is drawn forwardly its slot provides clearance for the blade-depressing rib it until the solid end portion of the blade encounters the rib. When this occurs the rear end portion of the blade is gradually forced downwardly as it rides along the rib l8 and consequently all the blades in the stack below it are depressed and carried below the delivery slot It so that jamming of two blades in the slot at the same time is positively avoided. When the rear end of the blade passes beyond the end of the rib IS the spring 2| is free to move the stack and bring the next blade therein up into contact with the top ii of the magazine. a

The top edge of the rear portion of the upstanding rib i3 is spaced fromthe top ii of the enclosure to provide full clearance for the uppermost blade in the stack. Therefore, the rear solid end portion of the blade may be moved forwardly without any obstruction until it encounters the rear end of the depending rib l8 by which it begins to be depressed as explained above.
