This invention relates 4to safety razor blades, and particu arly to packages for slotted blades.

A broad ob'ect of the invention 1s to sunplify the pa aging of safety razor blades and to provide aI container that will ve adequate protection to the delicate cutting edge or edges 'of a razor blade, and that will `permit of the `ready and convenient removal of the blades therefrom by the user.

As is well known, most safety razor blades are .used as they come from the package, without sharpenin therefore, it is important that the blade well protected by the package to revent impairment of its delicate cutting e ge or edges during shipment and hanlin Hretofore, blades have been commonly packed by wrapping each blade in wax paper, then placing it in an individual envelope, and placing a number of blades so protected in an ordinary cardboard container. This method of packin is objectionable because of the large num r of operations necessary to wrap each blade, the fact that the delicate cutting edges may come into direct contact with the Wrapping, and the inconvenience of havmg to free each blade from its multitudinous individual wrappings before it can be used.

in accordance with the present invention il eliminate the necessity of wrapping slotted razor blades individually,by providing a container havinga central guide adapted to fit in the slots in the blades and thereby center them in the container so that the cutting with the walls of the This simplifies the original packaging of the blades and their subsequent removal from the package by the consumer, and also gives more complete protection against mechanical injury to the cutting edges of the blades than is given by individual wrappings.

The invent-ion will now be explained with reference to the accompanying drawing in which Figure 1 is a perspective view of the component parts of my package with blades positioned therein;

ackages for v Figure 2 is a. perspective view of a portion of the package with the blades removed;

Figure 3 is a cross sectional view of a closed container containing blades Figure 4` is a cross sectional IV-IV of Figure B;

Figure 5 is a perspective view of a blade separator that may be tainer; and

. Figure 6 is a perspective view of an alternative form of construction to that shown in Fi re 2.

y package comprises an inner retaining member 1 and an outer telesco ing container 2, into which the member 1 is adlapted to slide.

view in the The inner 'member 1 is preferably madef of cardboard or heavy paper and has secured thereto a guidemember 3, which is also preferably made ofcardboard or heavy paper. The member 3 may be constructed and attached to the member 1 in various Ways but l have found it convenient to form the upper projecting tongue 4 b doubling the material back on itself an then forming wings 5 b bending the ends of the folded piece at rig 't angles to the tongue 5. Wings 5 may then be secured tothe member 1 by glue or other suitable adhesive.

The member 1 is scored at points 6 to facilitate the bending back of the ends over the central portion to which the guide member 3 is attached, and one end is provided with a slot 7 adapted to it over the top of the tdngue 4 when it is folded flat.

' An alternative method of forming the member 1 is shown in Figure 6 in which parts corresponding to those of Figure 2are indicated b the same numerals with the suliix a ad ed. ln this instance the tongue 4a is formed by cutting out and bending back a section of the member 1a itself. If desired,

the slot in the cover portion 10a may be conused with my conand a slot midway between the edges. These blades are packaged in accordance with my invention by simply placing them on the base member 1, the tongue 4 extending upward through the slots in the blades and holding them firmly in proper position. lf desired, the blades may be separated by slotted sheets of wax paper of the shape shown in Figure 5 to prevent contact between adjacent blades and to aid in preventing moisture from reaching the blades. These wax sheets are preferably slightly larger than the blades, as shown in Figure 5, in which a blade 8 is shown positioned between two waxed sheets 9. Suiiicient blades, with or without waxed sheets therebetween, are stacked on the member 1 to almost but not quite reach the top of the ton e 4. The end 10 of the member 1 contaimng slot 7 is then folded over on top of the blades so that the slot 7 engages the top of tongue 4. The opposite end 11 of member 1 is then folded down on top of the end 10 and the complete assembly inserted in the outer cover 2. The positions of all the elements of the package when it has been filled and closed are clearly shown in the cross sectional view of Figure 3.

llt should be particularly noted that the edges of the blades, supported as described by the tongue 4, are positively prevented from contacting the walls of the package. Thus, referring to Figure 4, it will be seen that the base 1'is of greater width than the blades to be packaged and that the edges of member 1 contact with the edges of the outer container 2. @bviously the member 1, because of its greater width, positively prevents the blades moving laterally into contact with the edges of member 2.

'llhe provision of a slot in the end 10 of member 1 which folds down on top of the blades in thepackage is also most important as this slot engages the upper end of the tongue 4 and thus centers the tongue with respect to the sides of the cover 2. Even should the whole package be crushed so that it assumes the shape shown in dotted lines in Figure 4, the tongue 4 is at all times maintained by the slotted end 10 in parallel relation to the sides of the outer container 2, thus preventing the edges of the blades from contacting with the container. Another practical advantage of the present container is that the removal of the blades therefrom is greatly simplified. Thus, the only operations necessary to obtain a. blade from this package are, first, the

removal ofthe inner member 1 from the cover 2, fsecond, folding back the ends 11 and 10. and, third, lifting a blade from the stack surrounding the tongue 4.

l claim:

A. container for slotted razor blades comaeeaava aged, a tab' of sheet material extending perpendicularly from said base portion to engage with slots in blades to be :vv ckaged and retain them in position, one othe ends of said base element being extended to fold back Hat against blades positioned on said tab and having a slot therein for receiving the up ver edge of said tab and the other end of sald) base element being extended to4 fold back lat on top ofsaid first end, said other end being substantially imperforate whereby it rests against the top edge of said tab projecting t rough said slot in said first end, and outer enc osing means for maintaining said ends flat against each other and against blades in the ackage.'
