SHEET 2 OF 4 FIG. 4 so PATE-NTED nsczz new saw u. 0F 4 MOLDED PLASTIC RAZOR BLADE DISPENSER BACKGROUND OF THE INVENTION Molded plastic injector-type razor blade dispensers are known in the art, being provided because of the advantages that plastic injection molding offers over the metal working techniques generally employed for making metal-bodied blade dispensers. Known types of plastic dispensers usually have a molded plastic body which is left open at the rear end to facilitate loading it with a stack of fresh blades, which opening is thereafter closed by inserting a suitable closure member in the dispenser body. The third essential element of the dispenser, the blade pusher with which blades are dispensed during the course of a blade change also is usually made of plastic and is retained in the dispenser body by interengaging shoulder means formed on both the pusher and the body. Dispensers of this type as known in the art, for example, the dispenser described in US. Pat. No. 3,288,328, have certain shortcomings. For example, criticality of dimensioning of the interengaging parts must be adhered to to ensure proper mating of the parts. Also these designs are usually such that they must be made by employing molding practices which inherently leave sinks and warping in the dispenser body surfaces oftentimes resulting in malfunction of the dispenser, for example, binding of the pusher with the top surface of the body.

SUMMARY OF THE INVENTION The present invention is concerned with an improved injector'type blade dispenser having a streamlined contour which makes it amenable to manufacture with plastic molding, the particular contour configuration being otherwise unattainable with the metal working bending and shaping procedures used for making metal-bodied dispensers. The dispenser is characterized by its simplicity of construction, ease of manufacture and economy of cost rendering it useful for throwaway when empty of fresh blades although it could be reused if necessary. It embodies a minimum number of parts comprising a plastic molded one-piece body having a streamline contour in which the forward end wall tapers in the direction of the rear end of the body and the bottom wall slopes downwardly from the front end wall so as to give the body a greater depth at the rear end than at the front. The interior of the body is divided into two compartments by a partitioned wall with the first or upper compartment serving as a vault for receiving a stack of fresh blades, the blades being supported within the vault on a spring that biases the blade stack upwardly in conventional manner to bring the uppermost blade in the stack in alignment with the blade exit slot as a requisite for dispensing blades. The other compartment serves as a used blade vault in which the used blade removed from the razor during blade change can be inserted through a suitable opening in the bottom wall of the body. The open rear end of the body is closed with an end clip which is provided with an angled lug at one comer serving as a blade positioning means in conjunction with a like angled lug formed at the forward end of the body adjacent the blade exit slot. The body lug and clip lug function to prevent the keen cutting edge of the blades in the stack from contacting any internal surface in the dispenser body either before or during the course of dispensing blades. Dispensing of blades is effected by sliding the uppermost blade from the stack with a pusher in the usual manner, the pusher being captively retained in the body in a slot at the top thereof, the pusher having lateral finlike projections the forward edge of which engages the rear edge of the uppermost blade. The pusher also is provided with a pair of relatively wide, relatively shallow lands which engage the upper surfaces of the dispenser body top to thereby minimize the contact surface of the pusher with the top so as to reduce the possibility of the pusher binding with the top because of irregularities in the surface of the top due to warping and other surface aberrations incident to molding operations.

An important feature of the invention in is the manner in which the body is designed to have sloping wall surfaces which facilitate molding of same and which contribute to enhancement of the appearance of the dispenser. The design of the end clip and pusher are in accordance with this thought and thus they are provided with corresponding configurations where they interengage with the body.

A modified form of end clip provides that the blade posi tioning lug instead of having an angled surface adapted to engage the angled corner of the respective blades is somewhat elongated in the direction of the dispensing end of the body and has a blade contacting face extending parallel with the cutting edge of the blade so that positioning of the blade stack can be controlled by abutment of the cutting edge of the blades against the lug, the extent of this engagement being however only along a length of blade cutting edge which when the razor blade is inserted in the injector razor is engaged by the razor head blade stops and hence is not used for shaving purposes. A similar shaped body lug is also provided at the dispensing end of the body and cooperates with the clip lug in positioning the blade stack. This arrangement thus provides positive blade positioning in the dispenser by allowing the cutting edge to make an acceptable contact against the end clip and body lugs.

The objects of the invention and its advantages will be made more fully apparent from a consideration of the preferred embodiments to be given hereinafter.

3 I DESCRIPTION OF THE PREFERRED EMBODIMENTS I The present invention is concerned with a plastic injectortype blade dispenser which is characterized by features of smooth contoured appearance embodied in a dispenser structure which is readily produced by uncomplicated plastic injection molding techniques. The dispenser is readily adapted to mass production manufacturing and is relatively inexpensive to make, thereby making it suited for throwaway once emptied of fresh blades. Moreover, the construction of the dispenser is such as to provide a high degree of reliability of operation with little likelihood of malfunction of the blade pusher, blade positioning meansand like elements.

The dispenser illustrated in FIGS. 1 and 2 is characterized by its relatively simple yet effective construction and ease with which it is assembled. It is comprised of three major component parts made of .molded plastic, a dispenser body providing a storage enclosure for a stack 12 of fresh blades, an end clip 14 for closing off the rear end of the body 10 after the fresh blade stack is loaded therein, and a blade pusher or slider 16 which is manipulated by the user to eject the topmost blade from the stack into the head of an injector-type razor when making a blade change. Turning now to a description of the specific constructional details of the several components and with continuing reference to FIGS. 17, the dispenser body 10 is an elongated molded plastic structure having a forward end wall 18 which inclines rearwardly as shown being integrally joined at its lower part with bottom wall 20, the latter sloping downwardly from front to rear since, as will appear, the body is considerably deeper at the rear than at the front. The latter not only contributes to the overall contoured appearance of the dispenser but also to a simplification of molding proceedures particularly with respect to facilitating withdrawal of core parts from the mold with which the body is formed. The top wall of the body 10 is formed by a pair of generally horizontal disposed panels 22, 24 which are spaced apart so that the inner edges of the respective panels define a slot 26 extending almost the full length of the body rearwardly from forward end wall 18, there being no communication of the slot through forward end wall 18. Thus, that part of the inner transverse edge of the forward end wall which bridges the slot 26 and which is slightly thicker than the main part of wall 18 serves as a stop abutment to limit dispensing travel of blade pusher 16 in the direction of the dispensing end. In a preferred form of the dispenser one panel 22 is slightly smaller in width than the other panel 24 providing that slot 26 is offset to one side of the longitudinal axis of the body. The body 10 also has a relatively broad front sidewall 30, a correspondingly coextensive back sidewall 32, both sidewalls being formed integral with the respective panels 22, 24, and the body also has a bottom wall with all the respective walls terminating at the rear of the body at a generally common location so as to define an open rear end therefor. As can be best noted from FIGS. 4 and 5, sidewalls 30 and 32 slope inwardly slightly from top to bottom for purposes of enhancing the appearance of the body, the inward slope of front sidewall 30 being somewhat greater than that of back sidewall 32. The interior of body 10 is also provided with a horizontal partitionwall 34 formed integral with forward end wall 18 and sidewalls 30, 32, and being of diminishing tapered width as shown, the partition wall 34 terminating a short distance from the rear end of the body in the mannerbest seen in FIG. 2, thereby allowing for recessed reception of end clip 14 within the rear end of the body. The partition wall 34 divides the interior of body 10 into an upper compartment 36 which supportingly receives a stack of fresh injector-type razor blades 12, and a lower compartment 40 serving as a used blade chamber for receiving used blades removed from the razor when making a blade change, the bottom wall being provided with a slot 35 providing access to the lower compartment 40 for inserting a used blade 15 therein (FIG. 2), the slot 35 extending through the thickness of back sidewall 32 as shown in FIG. 6. The stack of blades 12 is supported in upper compartment 36 on a bowed spring member 42 which when the pusher 16 is in its rearmost position biases the'stack upwardly (as can be best seen in FIG. 5)

urging theuppermost blade 13 against longitudinal ribs 44, 46 formed on the undersurface of panels 22, 24 respectively, in which position the uppermost blade registers with the blade exit slot 48 formed in forward end wall 18 (FIG. 3), the ribs 44, 46 terminating at the outer surface of front end wall 18. The dispenser body 10 also is provided with an integrally formed key 50 which in conventional manner is inserted in the razor head during the course of a blade change to open same and free the used blade for removal and also to properly align the dispenser blade exit slot 48 with the razor head to facilitate smooth entry of the fresh blade onto'the blade seat of the razor.

As previously mentioned, the open rear end of body 10 and into vertical steps 65,65a formed at the front sidewall 30 I and back sidewall 32, respectively, as shown in FIG. 4 thereby to complete the end closure as shown with the upper part extending forwardly a distance surrnounting partition wall 34. The end clip 14 is closely received within the dispenser body and is provided with a wedgelike projection 68 which extends outwardly from sidewall 60 and engages in a slot formed in the body back sidewall 32 so as to act as a locking means for retaining the end clip 14 securely in the body, the body back sidewall being amenable to sufiicient outward flexure to accommodate passage of the projection 68 preliminary to its en: gagement in slot 70 when inserting the end clip 14 in body 10. As can be best discerned from FIG. 4, the end clip sidewalls 60, 62 are closely conformed to the body walls 32, 30 respectively, and are dimensioned to tightly engage these surfaces to 1 ensure closure of the rear end of the body..Furthermore, the

steps 67, 65 and 65a which receive the rear wall of the end clip serve to prevent used blades present in compartment 40 from lining up with the seam formed by the end clip rear wall and. dispenser body walls and thus preclude accidental removal of same from the compartment. The end clip 14 in addition to closing off the rear end of body 10 provides means with which the stack 12 of fresh blades is positioned within the dispenser body in such manner as to maintain the keen cutting edges thereof out .of contact with surfaces of the body that could cause damage to the blade cutting edge. Positioning of the stack of blades, as best seen in FIG. 1, is provided by an angled lug 74 formed at the corner of the end clip defined by the juncture of clip front wall 64 and sidewall 62, the lug 74 having a vertical edge surface 75 disposed at an angle of substantially 45 with the longitudinal axis of the dispenser body, the

lug surface 75 being adapted to engage with the similarly angled comers 77 of the razor blades in the'stack 12. In positioning the stack of blades, the lug 74 functions in conjunction with a like-shaped but oppositely facing lug 76 formed integral with the forward end wall 18 and spaced a distance from the comer formed by the forward end wall and the front sidewall 30. As can be best noted in FIG. 1, the blade stack is main-.-

tained within the dispenser body in a position'in which the.

transverse edges thereof are held a parallel with the plane of the front wall 64 of end clip 14 and uniformly spaced from the.

forward end wall 18 with the stack however being capable of limited planar movement in the directions X-X and Y-Y as shown in FIG. 1. Thus movement in the lateral direction Y is limited by the inner surface of back sidewall 32 and lateral movement in direction Y and longitudinal directions X, and 1 X is limited by the clip lug 74, body lug 76 and body stop 76"-' the latter being formed on the forward end wall 18 spaced inwardly a distance from back sidewall 32 and having an abutment face surface extending perpendicular to the longitudinal axis of the dispenser body. Under normal conditions, the blade stack does not make contact with all of the just described surfaces simultaneously inasmuch as the blades must be free to move upwardly to position the uppermost blade 13 in register with the blade exit slot 48.

End clip 14 also serves to strengthen the overall rigidity of the dispenser body and particularly the prevention of any outwardly directed movements of the front and back sidewalls 30, 32 which otherwise would be possible by reason of the presence of slot 26 in the top of the body. For that purpose, the front wall 64 of end clip 14 is stepped down at its center part as at 130 leaving the upper part of the front wall 64 at the ends in snug fit with the underside of the dispenser body top and more particularly nested in the undercut slots 132, 134 of top panels 22, 24 respectively (FIG. 5). Thus, the ends of the upper part of the frontwall 64 closely fit behind longitudinal ribs 44, 46 so that outwardly movement of the top panels and hence the front and back sidewalls is not possible. Additionally, the ends of the upper part of the front wall serve to prevent the topmost blade in the blade stack from sliding toward the rear end of the dispenser body to the extent that the forward edge of the finlike projectionson the blade pusher 16 could not engage the rear end of the topmost blade as a preliminary to dispensing same from the body.

A modified form of end clip 120 is shown in FIG. 7 which differs from that just described with respect to the construction of the clip lug 122 which is used to position the blade stack within the dispenser body in conjunction with the body lug 124. Instead of having a blade positioning surface aligned at an angle with the longitudinal axis of the dispenser body and corresponding with the corner angle of the blades, the lug 122 has a blade positioning surface 123 which extends parallel with said axis. Similarly, the body lug 124 has its blade engaging surface I26 extending parallel with the body axis. The squareness of the blade stack with respect to the body exit slot and superposition of the respective blades is maintained by means of a body stop 77 formed integral with the forward end wall of the dispenser and having a blade abutment face extending perpendicular to the dispenser body longitudinal axis. The length of keen cutting edge of the blades that can engage with the end clip lug 122 and the body lug 124 corresponds generally to the part of the cutting edge which makes engagement with the blade stops in the razor head so that although engagement of the keen cutting edge with the lugs in the dispenser may damage same, it is an acceptable condition because the damage occurs along nonshaving lengths of the cutting edge. Furthermore damage to the cutting edge is minimized by the use of plasticfor the dispenser body and end clip. Obviously, the uppermost blade in the stack when raised up to dispensing alignment with blade exit slot 48 clears with lug 122 and 124, since the latter extend only to a height level with the secondmost blade in the stack.

Dispensing of blades is effected by using blade pusher 16 to slide the uppermost blade 13 from the stack 12 and through the blade exit slot 48 into the razor head, the procedure attending a blade change in an injector-type razor being well understood by those skilled in the art. The blade pusher 16 is a molded one-piece plastic element having a relatively wide upper or top part 79 which merges with a rearwardly inclined serrated surface 80. An important feature of providing the blade pusher with an inclined or downwardly sloping surface is that the latter provides an inclined plane facilitating the ease with which the pusher may be digitally manipulated, i.e., it enables the user to manipulate the blade pusher with the thumb alone, the inclined surface thus is adapted to receive a finger or thumb in such manner that simple articulation of the finger or thumb is sufficient to slidably displace the pusher.

The undersurface of the serrated upperpart of the blade pusher is formed, as best seen in FIGS. 2 and 3, with relatively narrow, laterally extending shallow lands 82 which engage and ride on the upper surface of the panels 22, 24 thus maintaining the major widened undersurface of the blade pusher upper part out of contact with the top of the dispenser and minimizing the prospect of binding of the pusher on the dispenser body in the course of the sliding travel of the former. The blade pusher also has a vertical lower part which is narrowed as at 84 to extend through body slot 26, the lower part widening as at 86 and extending forwardly a distance of the front edge of the upper part. The widened lower part 86 is provided with a set of flexible lateral finlike projections 88 which closely engage the undersurface of ribs 44, 46 and which present a front edge part on the blade pusher which engages with the rear edge of the topmost blade 13 in the stack in the course of dispensing. The finlike projections 88 are preferably about .066 inch thick and being in close contact with the ribs 44, 46, it is possible then for them to engage only the topmost blade in the blade stack since the latter also is engaged with the ribs 44, 46 but as common with most single-edge-type blades is .OlO inch thick. As seen in dashed lines in FIG. 1, the leading edge 90 of the pusher is, in the manner used in this type of dispenser, angled rearwardly from the front side to the back side of the dispenser body.

Dispensing of the uppermost blade 13 from the blade stack preferably involves applying a sliding force to the blade pusher 16 with the thumb held against the upper part of the pusher while grasping the razor body with the index and middle fingers and applying the sliding force with the thumb. in FIG. 2 the blade pusher 16 is shown at a location just prior to the point of maximum left-hand travel. The left-hand travel of the pusher is limited by engagement of the transverse surface of lower part 84 of the blade pusher 16 with the inner transverse edge of the forward end wall 13 bridging slot 26, the abutment surface of the latter being depicted at in FIG. 2. Maximum travel of the pusher to the right occurs when the rear trans verse edge 87 of blade pusher lower part 84 engages against the stepped upper part 69 of end clip back wall 66. when the blade pusher 16 is retracted to the full right-hand position, the under surface of the laterally directed pusher fins 88 pass clear of the blade stack permitting the spring 42 to raise to the topmost blade into register with the blade exit slot 48. The pusher is then slid from right to left with the leading edge 90 thereof engaging the rear end edge of the topmostblade 13 to apply sliding movement to said blade initiating the dispensing thereof. 7

An important feature of the present invention is the fact that blade stack 12 is positioned within the dispenser body 10 with a view to minimizing engagement of the keen cutting edges (with the exception of that associated with the construction shown in FIG. 7) of the blades against any internal surface of the dispenser body and also to orient the blade stack properly in the dispenser body to ensure proper registration with the razor head when making ablade change. This involves, as previously mentioned, employing means to keep the blade stack close against the back sidewall of the dispenser body. Concurrently, it is desirable that the blades when properly positioned, be dispensed in a plane parallel with the blade exit slot 48 and that the uppermost blade 13 when moved into register with said slot being so held that it moves parallel to the blade exit slot when being dispensed. In prior art dispensers, the under surface of the top wall of the dispenser generally merges with the back sidewall at a rounded corner, primarily a consequence of molding procedure limitations, so that at least as to the topmost blade in the stack, it is not possible to bring the back edge thereof into firm contact with the dispenser body back sidewall generally resulting in a cocking of the blade in which condition the blade cutting edge and back edge do not lie in the same horizontal plane. This problem is eliminated in the dispenser of the present invention'in the manner shown in FIG. 10 by employment of the pair of ribs 44 and 46 against which the uppermost blade l3 engages when the latter is in dispensing position. The presence of the ribs 44, 46 and especially rib 44 produces an undercut 103 in the bottom surface of the dispenser top panel 22 allowing the back edge of the blade 13 to engage the back sidewall 32 along a surface portion thereof which extends perpendicular with the plane of the blade exit slot 48. In addition to the foregoing the ribs 44 and 46 provide a level surface for the topmost blade in the stack to ride against, assuring that any irregularities or warpage in surfaces 132, 134 (FIG. will not cause the topmost blade to misalign with blade exit slot 48. The fact that the pusher finlike projections 88 also ride against ribs 44 and 46 assures a common locating surface for the blade and projections.

An alternate manner of providing dispensing of the topmost blade 13 in a plane parallel with that of exit slot 48 and also restricting lateral movement of the blade 13 in the direction of the front sidewall 30 without hazarding damage to the keen edge thereof is shown in FIGS. 8 and 9 wherein in addition to providing the underside of the top panels 22, 24 with ribs 201 202 which normally engage the flat side of the uppennost blade, the rib 202 nearest the front sidewall in corporates at 'one edge thereof an auxiliary rib 207 of rounded surface and provided at a location in which it engages the cutting edge part of the blade. The arrangement provides that this engagement occurs on the blade facet and at a location somewhat removed from the tip end of the cutting edge. The biasing effect of the stack spring maintains the cutting edge engagement with the rounded rib surface preventing lateral sideways movement and at no time in dispensing does the uppermost blade 13 move any closer'to the front inner surface of the front sidewall 30 than the position shown in FIG. 9.

From the foregoing description it is believed apparent that the blade dispenser of the present invention offers a number of important advantages over prior art constructions particularly from the standpoint of accurately controlling the positioning and dispensing of blades therefrom as well as simplifying the manufacturing and assembling procedures involved with consequent cost savings in the manufacture of the dispenser.

While there is disclosed but several embodiments of improvements of the blade dispenser of the present invention, it is possible to produce still a other embodiments without departing from the scope of the inventive concept herein disclosed, and accordingly it should be understood that all matter contained in the above description and in the accompanying drawing should be interpreted as illustrative and not in a limiting sense.
