(Cl. G-16) 13 Claims.

This invention relates. tov an improved razor blade pack of the type in which a seriesof blades are mounted on a flexible carrier strip with the strip itself being contained in a protective covering in such a manner as to constitute a. blade dispensing slide. The invention is herein exemplified as embodied in a package of safety razor blades of the Well known double-edged type. a1- though it is not limited to that type or to blades of any speoiiic shape.

It is a general object of the invention to improve blade packaging methods, and to provide an inexpensive blade dispensing packagey which will insure an exceedingly keen shaving edge of the blade against impairment from the time. it leaves the manufacturer up to the time it is selected by the user. It is. a further object of the invention to devise a razor blade pack hav'- ing a novel' blade dispensing aperture from which individual blades may, by means ofa relatively simple slide movement, be drawn forth with a minimum of eii'ort and simultaneously raised into an upright position to facilitate handling.

In one aspect the present invention is a solution of the problem of satisfactorily dispensing individual unwrapped, blades as distinguished from blades protected by individual packing or envelopes. The removalV of a thin safety razor blade from an individual envelope is not only somewhat troublesome for the user but is likely to cause impairment of: the shaving edge by accidental contact with the fold of the envelope. There is also involved' some danger to the user from cutting.

Much of thel unnecessary handling and inconvenience arising out of the removal of individual blade wrappers is eliminated in the blade dispensing package of the invention by arranging a series of blades directly in- Contact with one another on a carrier strip, with the ends of the blades being heldin longitudinally overlapping relation. The strip is slidably received in a sheath member so that the cutting edges on both sides of each blade are protectively encased between two opposite sheath surfaces which extend beyond these cutting'edges. In place of the usual operation of unwrapping eachy blade the user merely has to slide thevcarrier strip a short distance out oi the sheath to have `at handen un- L wrapped blade ready to be inserted in a razor and used. During this slide movement, the sheath or casing is held in Aone hand` and the strip pulled out with the otherhand; Danger of Z is only in contact with the fingers for a snortinterv-al at the time the blade is transferred from the pack to the rar/lorV body. Even thisv contact may, if desired, be avoided by engaging the razor directly in the blade slot, while the blade is still supported in the pack.

Another feature. of the invention consists in a series, of blades attached to a carrier strip in spaced-apart stepped relation so that each blade when not resiliently held in the sheath, normally presents a` free end extending angularly upward in an unobstructed position, from which it is convenient to tip or up-end the blades into a completely upright position. Combined with the blade and strip assembly noted is an open sheath or easing which is constructed withl guide mem.- bers extending throughout a part only oi'- the length of the sheath, thus dening a blade dispensing aperture from whichblades may be withdrawn.

In another aspect, the present invention consists in a bladeV package for blades having Well dened unsharpened end portions such as those found in safety razor blades of the double-edged type. Such blades are provided with corner notches whichdene each end of the blade and elongated unsharpened end portions of reduced Width as compared to the body of the blade. These end portions are further characterized by the presence of transverse openings. In `accordance with the invention, it is proposed'to package this type of razor bladez by inserting the reduced end portions through transverse slits in the carrier strip member, thus avoiding any need for separate fastening means. In order to loosely hold the blades in the strip as. they are Withdrawn from the sheath, the strip isfurther provided vvith longitudinally.extending tongue portions included between the extremities of the slits. The tongue portions-are bent upwardly and then caused to extend through the transverse openings in end portions of respective blades, thus affording a convenient holding means by which the blades can be pulled `along with the strip.

Another feature` of the bladepackage of the invention is a stop member centrally formed in one side of the sheath member'and projecting upwardly into contact with the strip so that' it liesfin the path of movement of the-reduced blade ends. ProvisionA is made for holding the blades and strip firmly against the sheath by means of tabs located at opposite edges of thev sheath. With` this-arrangement, as the strip is moved out cutting isthus greatly minimized since theY blade of the` sheath, the reducedendoi the-foremost blade is positively engaged against the stop member, and the tongue extending through the blade thereupon draws the engaged blade upwardly, pivoting it into an upright position. The blade is then easily detached from the strip, with the reduced end sliding out from between slitted portions of the strip and with the tongue falling away from the slot as the blade is pulled away.

These and other objects and novel features of the invention will be best understood and appreciated from the following description of the preferred embodiment selected for purposes of illustration and shown in the accompanying drawings, in which Fig. 1 is a plan view of the razor blade pack of the invention in position for removal of the rst blade;

The principal parts of the blade dispensing package shown in the drawings comprise a sheath which is open along `one side to form a blade dispensing aperture, and a blade carrier member slidably supported in the sheath in a manner such that it may move blades into register with the blade dispensing aperture. The carrier member consists of a rectangular strip I0 of thin cardboard, plastic or any stiff but exible material. I0 is formed with a. series of spaced-apart transverse slits I2 which are interrupted to define 1ongitudinally extending tongue portions I4. The sheath is generally denoted by arrow S.

Blades I6, I8, 2D, 22 and 24, as shown in the illustrated pack, are double-edged and each is further formed with a median slot 28. Each blade also has corner notches which denne elongated unsharpened end portions denoted in the case of blade I6 for example by the numeral 30. The end portions are reduced in width relative to the body of the blade and the outline of the end portions is emphasized by employing notches 'of re-entrant contour. It will also be seen that the median slot 2B has spaced enlargements c`onstituting openings 28 which extend transversely of the reduced end portions.

Each blade is separately attached to the strip by inserting one of its reduced end portions downwardly through a transverse slit in the manner indicated in Fig. 1 so that the blade is normally supported in the strip in an inclined position. From an inspection of blade I6 it may be seen that the shouldered portions of the blade engage upon uncut portions of the strip, with the re- Along its intermedi-ate portions, the strip duced end portion 30 passing through the strip and lying at the under side thereof. In the inclined position of the blade which results, the tongue portion I4 is conveniently bent upwardly and engaged through the opening 28 as suggested in Figs. 1 and 7, thus locking the blade into the strip IU so that it can be advanced along the sheath together with the strip.

The sheath member may be of any suitable material such as cardboard, plastic, thin metal and the like, and is vformed with a slide supporting surface 29 and upstanding retaining edges 3I and 32 within which the carrier strip I9 is supported. The overall width of the supporting surface and retaining edges slightly exceeds the Width of the carrier strip and the strip in turn exceeds in width the attached blades so that the cutting edges oi the blades are at all times protected. At the right-hand end of the sheath member as viewed in Fig. 1, are two guide members 34 and 36, which comprise downwardly extending sections integral with, and resiliently engaged against the slide supporting surface of, the sheath. It will be observed that the remainder .1 of that side of the sheath constructed with the guides is left open thereby defining and forming a blade dispensing aperture.

The strip and attached blades are normally packed between the flat face of the sheath and the guide members 34 and 36 in the manner illustrated in Figs. 1 and 2. It Will be seen that the ends of the blades are bent over upon one another in longitudinally overlapping relation with each blade being held in a flexed position. The

" guides extend along the sheath for an appreciable distance, thus providing an enclosure for retaining the overlapping blade ends when the carrier strip is advanced into the initial position shown in Fig. 1. The free outer end of the carrier strip normally projects well beyond the sheath in the position shown in Fig. 1 and thus furnishes a convenient tab which can be grasped between thumb and nger for withdrawing the strip and blades from the sheath.

The slide supporting surface of the sheath is formed with a centrally located upwardly projecting stop member 38 which preferably consists of a portion of the sheath upset to provide a curved edge more clearly shown in Fig. 3. The stop is spaced away from inner ends of the guide members 34 and 36 a distance slightly greater than the length of one of the razor blades so that each blade in moving out of the sheath becomes disengaged from the guides 34 and 3S before the forward end of such blade reaches the region adjacent the stop. It will be noted further that stop 38 is arranged directly in the path of movement of the blade and positive engagement of its vforward end is provided for by flexible holding elements comprising ears 40 and 42 which maintain the carrier strip ilatly against the surface of the sheath. Since the forward end of the outermost blade shown extends through the strip, its leading edge is pressed down against the sheath by the restraining action of the carrier strip and this edge comes to rest against the stop. The stop thus cooperates with the strip and its interlocking tongues to arrest movement of the forward end of a blade coming into contact therewith while the respective tongue portions tip the rearmost portion of the blade upwardly, pivoting it into an erect position such as suggested in Fig. 9.

In assembling the razor blade pack of the invention, the blades are separately attached starting at one end of the strip, with a. reduced end belng'thrist "througli itsY respective slot and the included' tongue being' brought 'into -interlocking relation with'the blade end asindcated in Figfe. The'zseveral blades th'us "assembled are then Iforceddowri upon one 'another into longitudinally overlapping position and While in the" resulting 'flexed positioninserted in the sheath between the sud@'suppcrtingsurrceand theguides. The-free end'fof the'strip ispas's'e'd' 'under the holding ele- `inei'xts atthe' end ofthe sheathV and if desired an outer Wrapper or casing vmay be att-ached to the pack to seal the blades against dust, moisture, brother foreign matter.

' "When the user desires to secure a blade, he may conveniently 'graspthe sheathin one hand and witli'theother pull out'onY the Afree end' of the strip. 'As this is done'the rst blade in the series passes out from under the endsof 'the guides 34 an'dfSBlin'to lregister with the blade dispensing aperture ofthe sheath.' "Immediately the blade Springs upwardly" intov a slightly stepped position as shown in Fig. '1.` This is due to the restraining action' ofthe strip which, in 'response to"'the pressure'of'the'holding'el'ements Ml'and V42, is directed against the underlying reduced end oi. th'ebladewith the result that aA limited fulcruming action takes place, inducing an initial upward movement of the blade. In this slightly raised position, the blade is carried forwardV a very short distance until it trips 'against the stop member. As the forward edge oi the blade comes to rest against the stop, the pull of the'strip is transerred to the respectiveinterlocking tongue which tips the blade, swinging it out through the blade dispensing a ertur-e into an upright position as shown in'Fig'fQf' The'blade' may then be picked up between nnger an-d thu-mb and slid outv of the Strip with the tongue readily, falling away.

11' Will bt nOtQd. that. the` Spacing o-f the'several blades in the series is so chosen that the next -Sulfedng blade on the stri-p remains in engagement with the` guides during the peri-od that the outermost blade iS. beineA released and upended. thus leaving the remainder o f the pack in a fully RrQteQted. @OndtQIL TQ Wthdraw'v another blade. the fivleQf Operation above described is recreated with the strip being moved outwardly` anadditiene-1 distance..
