Referring now in detail to the numeral 10 denotes a co ntainer constructedin accordance with the presentinvention to serve standard double edged blades 83 longitudinally slottedat 85 as shown in Fig. 2. two separately formed parts 12 and 14 (see Fig. 2) made of any preferred or desired material, such as forexample a commercial synthetic plastic. Part 14 is the base or ,lower'part and part 12 is the upper part.

The upper part 12 of the container includes two depending side walls 18, 19 (Fig. 6), front depending end wall 20 (Fig. 5), rear end wall 21 and top wall 22. A continuous step 24' runs around the top edge of its front end and extends along the major length of the sides. A slot 26 shown as of a width greater than that of a razor blade to be fed therethrough, is formed in the vertical front part of said step. Slot 26 is shown a of a height slightly greater than the thickness of a bare razor blade.

drawings, the reference The container body is shown as comprised of One feature of the invention contemplatesthat the I l'y-ing relation to the already entered used blade. It

topmost of a stack of blades-in the containenbe'inoved through discharge slot 26 by finger engagement through opening 28 provided through top wall 22 of the upper part and whose width is defined by the spacing between side edge portions 28' which define the opening. This width is shown as such that a finger, preferably the human thumb, is enterable thereinto sufficiently to engage its fleshy underpart with those portions of the topmost blade which are rendered accessible thereto by opening 28 and the following provisions are made whereby the thumb is guided into opening 28 and therealong to advance the blade, thumb engagement with the topmost blade is facilitated and thumb movement controlled against slippage. Among these provisions are the following: the side edges 28 are extended rearwardly as shown at 28 to define channel portion 30 to the rear of opening 28 and thus extend rearwardly the passageway between its edges 28; these side edge extensions 28 are continued rearwardly to the rear end of the container as side edge portions 32, which are however directed angularly outwardly to provide the passa eway between edge portions 28 and 28 with. an enlarged mouth 34 which gradually increases in width toward the rear end of the container; the edges 28, 2S and 32 which define the passageway are bevelled upwardly and outwardly from the level indicated at a in Fig. 6; a platform 45 to the rear of opening 28 and extending forwardly from rear wall 21 to initially seat the thumb, is levelled to the top of discharge mouth 26 and the undersurfaces of edge portions 28 and 32; portions of the top surface of top 22 to opposite sides of the passageway defined by edges 28', 2S and 32, are provided with inclined grooves 36 generally parallel to the outwardly diverging edge portions 32, each groove having its rear wall vertical and its front wall inclined upwardly and forwardly relatively thereto.

As a result when the thumb is seated on top surface 46 of platform 45 and then advanced, it will be guided visually and physically by the edges 32 into the narrow portion of the passageway wherein it will be pinched sufiiciently by the side edges 28 to depress the fleshy parts of the undersurface of the thumb downwardly through opening 28 and into effective. engagement withthe blade and in such advancement the diagonal grooves 36 will tend to prevent thumb slippage.

Base 12 is provided with an upstanding peripher flange 47 inset from the periphery of the base at all points except at the front end. The flange is adapted to' snugly fit within the walls of the upper'part of the container.

-An inlet slot 50 is provided in the lower left corner of the container so that it opens downwardly through the bottomand also forwardly through the front. This slot shown as somewhat wider than a razor blade and slightly deeper than major blade thickness, is extended rearwardly by opening 52 in said base, immediately to the'rear thereof and into which the slot opens for its full length. This arrangement permits the advanced end of a used blade to be entered substantially horizontally into inlet 50.

The transverse edge portion of the bottom whichdefines the rear end of bottom opening 52, is bevelled at a relatively low angle, upwardly and rearwardly from the base bottomto the base top, to provide ramp 54, which'will engage the advanced edge of the blade being entered through mouth 50 and direct it upwardly so that the fully entered blade will seat itself onto the base bottom.

The lower portion'of ramp. 54 is recessed centrally as shown at 56 for entry of the pushing finger (human)- to assure entry of the distal end of the blade approximately to the innermost portion of the recess. When so fully entered, the used blade will present that portion of its distal end which overhangs the unrecessed upper ramp portion in spaced relation thereto, so that the entry of a following used blade will be guided thereby into under- 3, be understood that used blade entry is resisted by the downward pressure of overlying spring 62, so that overthrow of the blade is minimized.

The base is assembly with the upper part and the two are he'l'd together as will now be described to present inlet slot 50 and ejection slot '26 at the top and bottom of the front end of the container, for convenience of operation.

The side walls of the upper part '12 are each provided with spaced apart downwardly extending tabs 109 (Fig. contoured, dimensioned and located to engage in notches 110 provided in the side portions of step 24 of the lower member 14 to thus guide the two parts into assembled relation. The two parts are locked in this relation upon their assembly by engagement of projections 112 which extend outwardly from the upper end of flange 47 of the lower member, in indentations 114 provided on the inner I surfaces of the side walls of the upper member. it will be observed that projections 112 and indentations 114 are located vertically above cutouts 110 and tabs 109, respectively.

This assembly operation must include and be preceded by the step of loading the parts 12 and 14 with blades and spring 62. One manner of effecting this is as follows: spring 62 is entered into and seated on lower member 14 and blades are entered into upper part 12 preferably while this part is held upside down; the upper and lower parts are then assembled in locked relation, as already explained. In this final assembly step, it is advisable that the blades and spring be held by hand in their respective parts.

The spring 62 hereinabove referred to, comprises a body portion 66, shown as flat and dimensioned and contoured to be received initially within peripheral flange 47 of lower casing portion 12. Its ends are upturned to provide flanges 68 which serve to guide its up and down movement and also to prevent used blades from being inserted thereabove.

Spring 62 has two laterally related spaced apart spring fingers 70 and 72 extending upwardly from and transversely of the middle of the spring body or base 66 and a spring finger'74 extending upwardly from the rear portion of base 66 and to the rear of fingers 70 and 72. Said three fingers all extend generally in the same direction and it is contemplated that the spring be positioned in the casing so that these three fingers be forwardly directed toward the mouth as shown in Fig. 3, so that the upper curved free ends thereof all face in the same direction. The spacing between and the location-of fingers 70 and 72 is such that these fingers engage the blade portions of the lowermost blade of the stack to opposite sides-of its longitudinal slot 85. The width of finger 74 is such that its central location assures its engagement across and to opposite sides 'of blade slot 85. It will be observed that fingers 70 and 72 engage and elevate the front end of the stack and that finger 74 engages and elevates the rear end of the stack and that the three fingers are directed toward the container front. The position within a container stacked only with new blades, of spring 62 and its aforementioned fingers 70, 72 and 74, is shown in Fig. 3.

An upwardly and forwardly directed centrally located spring'finger90 is interposed in the space between spring fingers 70 and 72 of a character and for a purpose to be set forth sholtly.

The body "66 of the spring is located by pairs of projections 99, 100, 101, 102 on the upper part. One pair of projections is disposed in spaced apart relation, on the inner surface of the rear end of the upper part of the dispenser. The other pair of projections are disposed respectively on the inner surfaces of side walls 18 and 19. These projections taper downwardly at their lower ends into their respective Walls and terminate at a level which clears the flange 47 ofthe lower part 14 for the assembly of the parts, all as shown in Fig. 3. The spring will lie initially below the projections and will be guided thereby when elevated by the entry of used blades therebeneath.

The container is provided with means for locating and holding the blades with their shaving edges in vertical registration and held out of contact with the container walls and it will here be premised that the container shown in the drawing is designed to take 20 new blades, although a specific number is not required by the invention. The blade locating means comprise a rib 80 extending longitudinally, centrally downwardly from top wall 22, and centrally located upwardly and forwardly directed finger 9-0 of spring 62. The Width of rib 80 and ifinger 9.0 are no greater and preferably less than the narrowest widths of the irregularly shaped slot of the standard blade so as to be enterable thereinto. The length of rib 80 is such that its engagement through the slot of the topmost blade, will :locate :that ;blade in the stack and also guide it rectilinearly as it is advanced through mouth 26. its depth is such that this engagement is not only with the topmost blade but also with a few (about five or six) blades immediately therebelow. Its location is immediately to the front of opening 28, and its front end is spaced from exit mouth 26 by a distance slightly greater than the length of the unslotted front end portion of blade '83 which will be free to seat between rib 80 and mouth 26. The lower surface of rib 80 is curved or beveled upwardly at its front 81 and also at its rear 82 as shown in Fig. 3.

As a result, advancement of the topmost blade can be effected freely by thumb engagement without flexing the blade until the rear unslotted end thereof engages bevel '82 and is flexed downward to pass under and clear it, which is practically feasible where the rib depth engages up to about 5 or 6 blades. It will be observed that where the advancement of the topmost blade carries with it the blade immediately therebelow, mouth 26 will prevent advancement 'therethrough of this second blade.

The length and location of centrally located finger is such that where the casing parts are loaded and fully assembled, its free end will be entered into the registered slots of the blade stack through the bottom thereof .to engage its curved top free end 91 with the underface of rib 80 with a sulficient pressure to effect its intended purpose. Finger 90 therefore serves for the blades below rib 80, a purpose similar 'to that served by the rib for the blades thereabove.

A further provision to retain the blades stacked above spring 62 against lateral shift and with their edges registered and protected against contact with the container walls, comprises depending flange 87 at the front of platform 4'5 having forwardly directed and upwardly extending ribs 83, located so as to engage in the cut away cornerportions at the blade end which characterize this standard blade (see Fig. 2) and receive therebetween the extreme end lobe of the blade, left by the corner cutouts.

A blade moved out of the container through top mouth 26 for placement in a razor, will be replaced by the discarded blade when it is entered into the magazine below spring 62 and the pressure of the spring will therefore remain constant. It will however rise gradually in the container with successive replacements.

What I claim is:

l. A blade dispenser comprising an elongated enclosure having an exit slot at one end and a recess-opening at the top wall located rearwardly of said exit slot through which a finger may engage the topmost blade to advance it and a platform to the rear of the opening presenting a top surface which is leveled to the top of the slot, an enclosed stack of double-edged blades underlying .said opening, said stack of blades having cut away corner portions, said platform having a flange depending therefrom to present a front wall Whose depth is at least equal to the .depth of the blade stack, said front wall presenting spaced apart ribs to enter the cutaway corner portions of the standard double edged .slotted blade 10 thus locate the .rear end .of the stack withreference to the opening through .the top.

2. A blade dispenser comprising an elongated enclosure having an exit slot at one end and a recess opening at the top wall located rearwardly of said exit slot through which a finger may engage the topmost blade to advance it, and a platform to the rear of the opening presenting a top surface which is leveled to the top of the slot, an enclosed stack of double-edged blades underlying said opening, said platform having a front wall whose depth is at least equal to the depth of the blade stack, said front wall including means cooperating with portions of the blades to locate the rear end of the stack with reference to the opening through the top.
