BLADE CONTAINING AND DISPENSING DEVICE Filed Jan. 27, 1947 Patented Jan. 1, 1952 BLADE CONTAINING AND- DISPENSING DEVICE Nicholas Testi, Boston, Mass., assignor to Gillette Safety Razor Company, Boston, Mass., a corporation of Delaware Application .lanuary 27, 1947, Serial No. 724,680,,

7 Claims. (Cl. 206 1'6) The present invention comprises anew and improved device for containing anddispensingsafety razorblades.

An object of the invention is to provide a device at low cost which may be filled by the blade manufacturer, which will adequately protect the blades against damage in the storage, distribution and sales intervals, and, which will provide the user with a convenient reservoir from which he; can draw the individual blades as required for use.

The fine cutting edge of a safety razor blade is so delicate-in, its structure, that it may be easily damaged byany chance contact occurring before actual use. It is desirable that the manufacturer, who is best qualified, to produce the fine. edge of the blade, should also protect and pack the blades so that they may arrive safely in the users hands.

The device of the present invention meets all the requirements above discussed and has other advantages, which will be pointed out hereinafter. Among these is the capacity for conveniently handling double-edged slotted blades of, a Well known type.

Going more into detail, the device of my in,- vention comprises a base having spaced upright studs thereon for use or in combination with a stack of slotted blades, arranged instaggered relation on; the base, with alternate blades inrpaled on difierent studs, but each blade being free to move in one direction only, and a. top or cover portion or-member secured to the base, at least partially covering and holding the, blade stack in place while exposing a substantial area of the uppermost blade in the stack whereby the latter may be engaged by the user and displaced for removal.

The studs are separated by an open, unobstructed space and thuseach slotted blade is free to move longitudinally a distance determined by the length of space between the studs. It is believed' that slotted blades have not heretofore been positioned in staggered relation on studs having an open'space between them and such combination and arrangement constitutes a further feature of the present invention.

These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof selected forpurposes of illustration and shown.v in theaccompanying drawings in which:

Fig: l. isa. view in perspective of the device on an. enlarged scale Eig; 2 :is:a.v-i'e w-- in longitudinal section on the. linezwl ofFiga. 1;; and.

Fig. 3- is a view in perspective showing a blade displaced for removal.

An important feature of the blade containing and dispensing device herein shown is that it may be constructed at such moderate cost that the manufacturer can aiford'to supply it merely as an item of blade packing which may be discarded when it has served its purpose. I I

The illustrated device comprises a rectangular base 10 having parallel longitudinal ribs orflanges at its opposite edges and spaced upstanding longitudinally-aligned studs [3' and I4 located in its median axis. The base It may be molded of'any suitable synthetic resin such as Vinylite orthe like. attached to the base III by dowels but it will be understoodthat as a general thing these studs will be molded as an integral part of the base. They are long and narrow in contour, located an equal distance within the ends of the base l ll and'have rounded inner vertical faces.

Attached to the base I0 is a metallic top or cover member l5. This may extend across the middleof the bottom of the base I0, and may be held inplace by a dowel stud it which fits snugly into a hole provided for it in the bottom of the base. The cover member extends upwardly across the outer walls of the ribs I l' and I2 of the base and then inwardly in the form of opposed wide U-shaped flanges l! and la; The cover member I5 is formedjof spring metal and its flanges l1 and I 8 tend always to spring downwardly toward theinner face of the base Ill. The two cut-out portions of the flanges l'! and I8 provide an open-f ing of substantial area the device as a whole.

The device is shown as containing a stack of 6 longitudinal slotted blades 20 of a well known commercial type, that is to say thin double-edged blades having a notch in each corner which notches together define unsharpened elongated end portions which close each end of the blade. Each blade is also provided with an elongated located at the center of median slot of" substantially the same length as the sharp edges of the blade and provided with spaced transversely-extending enlargements designed to fit the blade-locating projections of razors in which the blades are to be used. The blade slots are of such width as to fit freely over the studs !-'3' and I4 and when impaled on these studs the blades are held positively with their sharpened edges out of contact with the ribs H and" l-2of the base while permitted to movelongitudinallywithout binding on the studs. The'studs: I 3i-and Ht are so-spaced' that the blades 20 may be located in. staggered relation thereon,

As herein shown, the studs l3 and Mare with alternate blades impaled on different studs and each blade free to move longitudinally in one direction only a distance equal to the length of its slot minus the length of the stud upon which it is impaled. As shown in Fig. 1, the uppermost blade 20 is impaled upon the right-hand stud 13 with its solid end portion in contact with the outer wall of the stud and the other end portion of the blade 20 is located in substantial contact with the inner vertical face of the stud it. That blade therefore is free to move toward the right until its solid left-hand end brings up against the stud 13. Similarly the second blade in the stack is impaled upon the: stud l4 with its inner end in contact with the inner vertical wall of the stud l3, and that blade is free to move longitudinally toward the left.

In assembling the illustrating device for distribution, the blade manufacturer may supply the blades 20 to the base in the staggered relation above explained by automatic machinery or by any means which will adequately safeguard the sharp edges of the blades. The cover member I5 is then placed and attached to the base and through spring action holds the blades of the stack securely in the position shown, that is to say with the opposite ends of the blades substantially flush with the ends of the base H3 and with their sharpened edges, as already noted, safely clearing the ribs H and I2. It will be noted that the flanges I1 and I8 of the cover member may be so spaced as to permit the cover member as a whole to be slipped into its position past one or other of the studs l3 and M.

The completely loaded blade containing and dispensing device is shown in Fig. 1 as ready to be wrapped or packaged for distribution. When it reaches the user, he has only to engage the uppermost blade 20 with the fleshy portion of his thumb, as shown in Fig. 3, in the area of the blade exposed by the cut-out openings in the flanges l1 and I8 of the cover member, and to work the blade longitudinally toward the right in opposition to the yielding resistance of the cover member. In Fig. 3 the uppermost blade 20 is shown as displaced longitudinally nearly to the limit of its movement in its initial plane, that is to say, the left-hand end of its slot has been moved almost into engagement with the inner wall of the stud l3. It will be noted that the contour of the end edges of the combined flanges I1 and ii! of the cover member corresponds generally to the end contour of blade. Accordingly. when the blade 20 is moved endwise to the position shown in Fig. 3, its inner end passes substantially out from beneath the flanges of-the cover member. It is thus freed and may be conveniently grasped by the user and conveyed directly to the razor.

The blade 29' in the stack which now becomes uppermost is however impaled upon the stud I4 and is free for movement toward the left ill-- stead of toward the right end of the device. Accordingly when the user desires to remove this second blade, he proceeds as before, engaging the middle portion of the blade with his thumb and advancing it endwise out from beneath the flanges of the cover member but in the opposite direction from that in which the previous blade has been moved, unless the device has meanwhile been reversed end for end.

The resilient downwardly-extending flanges l1 and [8 of the cover member, which in the illustrated embodiment of the present invention serve as the blade-restraining means, include bladecontacting portions of relatively limited area which are located longitudinally inwardly of and below the tops of the spaced studs 13 and I4. These blade-contacting portions follow down the blade stack as it is reduced in height by the removal of successive blades. The flanges have sufiicient range of yielding movement to retain a single blade in position or to maintain a stack of five or ten or more blades in position. In each instance therefore the blade which is uppermost in the stack or the last remaining blade of the stack is yieldingly held below the tops of the studs and in the position in which it is initially placed in the device, being at the same time free for frictional movement in one direction or the other from beneath the cover member, and while the underlying blade is held against movement with it.

While the uppermost blade is free to be moved toward the right under the traction of the users thumb, the next underlying blade is held positively against movement in that direction by the engagement of its left hand solid end with the edge of the stud M. Like conditions exist as blade after blade is withdrawn. Thus the ejection of one blade at a time is efiected without ever danger of displacing a second blade.

Having thus disclosed my invention and described in detail an illustrative embodiment thereof, I claim as new and desire to secure by Letters Patent:
