United States Patent RAZOR BLADE PACKAGE Barfllqlomew A. Holollan, Little Neck, N. Y., assignmto Club Razor Blade Mfg. Company, Newark, N. J., a corporation of New Jersey Application July 11, 1956, Serial No. 597,250

1 Claim. (Cl. 206-16) This invention relates to magazines for razor blades or the like, and more particularly, to a novel magazine of this type arranged to contain a plurality of blades separated by paper strips acting as lubricators and in which all of the blades are removed from the same end of the magazine.

This application is a continuation in part of my copending application Serial No. 559,862 filed January 18, 1956.

The modern trend in dispensing razor blades is to sell packages of such blades in magazines of relatively rigid material such as metal or plastic composition materials. This magazine contains springs normally maintaining the blades engaged with one or more lugs extended through the blade slots. Most present magazines are relatively complicated in that the blades must be alternately removed from opposite ends of the magazine, which requires that the blades be so placed that arrows imprinted thereon indicate the removal direction. In addition, should the magazine be subjected to moisture, the blades tend to become rusted or stuck together.

In accordance with the present invention, a novel magazine is provided in which paper strips are disposed between adjacent blades. The magazine includes a pair of posts or pins or the like engaged through holes in the paper strips so that these latter are permanently held in the magazine. Also, the paper strips have cut-outs corresponding in size and location to the usual access opening for placing a finger against a blade so that normally the paper strips are invisible.

The magazine comprises a bottom or base section having side walls and one end wall, the side walls being curved downwardly toward the open end, and a cover curved at one end to conform to the side wall curvature. This cover carries a pair of ribs parallel to the side walls and serving as seats for a spring urging the stacked alternating blades and paper separators toward the base. The edges of the cover are formed for snap interlocking with the base side walls.

The stacked blades and separators are pushed by the spring against positioning posts around the access opening in the base. These posts are of such a height as to maintain the blades above the lower edge of the lug extending from the cover and engaged in the blade slots. If a blade is pressed to move toward the discharge slot between the cover and base at the open end of the base, it remains in engagement with the lug until such time as the end of the blade slot engages with a rearwaid extension of the lug. At this time, the reduced end portion of the blade falls between a pair of spaced posts, which lowers the blade sufliciently to pass beneath the lower end of the lug for withdrawal.

The paper separators not only act as lubricators separating the individual blades but also have tabs entering the blade slots to lock underlying blades against movement when the outermost blade is being withdrawn.

For an understanding of the invention principle, reference is made to the following description of a typical 2,870,905 Patented Jan. 27', 1959 embodiment thereof as illustrated in the accompanying drawings. In the drawing:

Figs. 1 and 2 are, respectively, top and bottom plan views of the loaded magazine;

Fig. 3 is a sectional view on the line 3--3 of Fig. 2;

Fig. 4 is an exaggerated side elevation view of the blades and separators, illustrating the locking tabs on the separators;

Fig. 5 is an inside view of the base;

Fig. 6 is a sectional view on the line 66 of Fig. 5;

Fig. 7 is a plan view of the spring;

Fig. 8 is a side elevation view of the cover; and

Fig. 9 is a planiview of a paper separator strip.

Referring to the drawings, the magazine includes a base member 10, a cover or closure member 20, and a spring 30. Members 10 and 20 are formed of any suitable relatively rigid material such as metal or a plastic compositionmaterial.

Member 10 includes a flat wall portion 11 formed with an oval access opening 15 around which are short posts 12 having their outer ends ina common plane. Extending from wall 11 are parallel side walls 13, having curved forward ends 14, and an end wall 16. Just rearwardly of opening 15 a pair of pins 17 project from wall 11 for a purpose to, be described. A lip 18 extends across the forward open end of wall. 11.

Member 20 includes a main wall 21 arranged to lie between walls 13 of member 10 and curved, as at 22, to conform to the curvature of the forward ends of walls 13. Wall 21 seats in grooves 31 in base side walls 13 and has lugs 32 along its side edges formed for snap engagement beneath lugs 33 on walls 13.

For a purpose to be described, the rear end of wall 21 is recessed, as at 23, and formed with a tapered or feathered portion 24. Ribs 28 extend parallel to the side edges of wall 21 and lie against walls 13 of member 10. A projection 25 extends from wall 21 and has a rearwardly projecting arm 26 and a sloping guide surface 27,

the lower surface of arm 26 being substantially in the common plane of the ends of posts 12.

Before assembly of members 10 and 20, the magazine is filled with blades 40 separated from each other by paper strips 45. The blades 40 are arranged with their reduced outer ends 41 engaged between posts 17, and paper strips 45 have holes 47 receiving these posts. The assembly of alternating blades and paper strips is pressed toward wall 11 of member 20 by spring 30, with the blades resting on posts 12 around opening 15. Strips 45 have cutouts 46 conforming to opening 15, so that only the blades are exposed at this opening.

As best seen in Figs. 3, 5 and 7, spring 30 is bowed and formed with a slot 34 to engage lug 25. The bowed surface of the spring engages cover ribs 28 and the spring ends engage the stacked blades and separators.

The blades are normally locked in position by engagement of lug 25 in blade slots 42. To discharge a blade. a finger is pressed against a blade through opening 15 to slide the blade toward lip 18. During this movement, slot 42 remains in engagement with lug 25. As the end of the slot reaches extension 26, the end of the blade is pressed between this extension and posts 12 with blade extension 41 dropping between the forward pair of posts 12. The blade then slips along guide surface 26 for removal through the open front of the magazine.

The paper strips 45 are held in the magazine by engagement of posts 17 through holes 47, and act as separating lubricators between the blades. These strips thus prevent the blades from sticking together due to'rusting or the like. Strips 45 have tabs 48 which enter the slots of underlying blades, as seen in Fig. 4-, to lock these blades against movement while a blade is being withdrawn.

3 It will be noted that the height of posts 12 is such that the blades are kept above the lower edge 27 of abutment 25 until such time as the blade has been withdrawn so i that the rear edge of slot 42 engages extension 26. At this time, reduced end 41 of blade 40 falls between forward posts 12 so that the blade is now below edge 26 and can be withdrawn.

Used blades are stored in a chamber defined by the inner surface of wall 21, the longitudinally extending ribs 28 and the bowed surface of spring 30.

While a specific embodiment of the invention has been shown and described in detail to illustrate the application of the invention principles, it will be understood that the invention may be embodied otherwise without departing from such principles.

What is claimed is:

A razor blade dispensing magazine comprising, in combination, a disengageably interconnected base and cover cooperably providing a pair of spaced substantially parallel walls arranged to form a blade discharge opening at one end of the magazine; the base wall having an access opening therein and posts around 'said opening having their outer ends in a substantially common plane parallel to the base Wall; the cover wall having a lug projecting therefrom for engagement in the usual central slot of razor blades; said lug being between such access and discharge openings and extending inwardly to at least such substantially common plane; a plurality of blades disposed in said magazine; a plurality of paper separator strips disposed in said magazine in alternation with said blades; interengaging means on said strips and in said magazine retaining said strips in said magazine as the blades are dispensed, said interengaging means in said magazine engaging the ends of said blades furthest from said discharge opening to prevent movement of said blades in a direction away from said discharge opening; and spring means engaged with said cover wall to bias the blades toward said posts whereby outward movement of the blades is limited by engagement of said lug in the blade slots; said posts including a pair at the discharge end of said recess spaced laterally substantially the width of the usual reduced end of a blade whereby, when a blade engaging said posts is moved outwardly to near the limit provided by engagement of said lug in the blade slot, the reduced width end of the blade, moving between said pair of posts, will displace the blade inwardly for outward movement beneath said lug, each strip having a tab extending into a'blade slot to retain underlying blades against movement when the blade engaging said pair of posts is dispensed.
