' This invention relates to improvements in receptacles to contain a series of superposed edged blades adapted to prevent the edge or ed es of the blades from contacting with a wall of the receptacle M a More particularly the invention relates to receptacles cont' ining razor blades, particu larly of the safety razor type, from which i the blades can be removed in a predeter- 1 ined succession and into which the blades gammy can beintr'oduc'ed in a predeterinined Succession. A fuither objebt (if the inyention is to provide alanine of manufacture comprising a plurality of Superimposed razor blades contained in a receptacle of the character described in such a manner that the edges of the blades cannot Contact with the walls of the receptacle and from which the blades can bereadily removed in a predetermined succession and afternse can be readily inserted into the receptacle or box successively lu aneath the blades remaining in the recep- I appli able to a dresser-box and is of substantlallycylind-i ical form. It comprises a base nine or box.

2 Uther objects and features of the invention will more fully appear from the following description and t e accompanying drawings and will be particularly pointed ou't'i'n the claiins. d y i As is wellknow-n, razor blades, such as blades for safety, shaving apparatus, retain an edge when used, onlyfor a relatively short time and are in general not intended for re-g'rinding. Likewise it i'sa known conclition that the edge of a razor or shaving apparatus blade is improved by non-use, or so to speak becomes better by lying, if the same without regrinding or stropping is left unused for some time. The invention is 40 based upon this characteristic of edged blades and comprises nieans 'for permitting such improvement in the edge of the'blade by causing the same to; be unused during a considerable period before it is again em,

pleyed.

tion, illustrated comprises a receptacleor box for holding shaving blades in uch amanner that a suitable number of blades which are laid therein in superposed relation can be removed from. the receptacle or boz r only] used blades are inserted in itin such a. man:

The'particular ernbodirn'ent of the invenner that the last one but in else the last one to be removed from the receptacle.

Thus the blades whichfa're successively re in'oved for'use and returned to the receptacle 1n the same order are given an opportunity to improveby lying? during a 'sulfieient time before they are again used; H v I Preferred embod'n'ients of the inveiitien are illustrated in the "accompanying draw,

ings, in which, i a

Fig. 1 1s a longitudinal sectional view,

about twice the normal size, of a bo'x -or receptacle containing a plurality of super imposed safety razor blades; i Fig. '2 is a plan View of th in 1 of approximately 'norinal sifie Fig. 3 is a bottom plan view of a different construction embodying the ,ii1i enti0n,c and box illustrated a Fig. its a longitudinal seaie niviw of a r'eeepa ie 'or box embed ing the invention having hinged lids direct op osite ti) each other. i V i i t I t The co struction'illnstrat diii is 1 a surrounding wan 2, nd a top, a which ma be of integral const'ructi'on, thetcp a having a peripheral fl nges aiaptedcp fit over the [edge of the enmunuangwnl P2.

The base 1 is also provided with a preferabl semi-cylindrical, lid -7 having a peripheral flange 8. fitting the "surrounding wall 2. The

base 1 desirably is provided with an aperture 9, directly beneath the lid \4, through {which the finger of the operator inay beinserted to raise the pile of superimposed blades ,sufiifciently t6 enable the uppermost tnaemuuy to be withdrawn from the box.

The lidsfi and 7, of course, need not be 'of semlcylindrical forrn, nor need they be hinged to thetOp Qr'bottoin of the box [If sliding lid or one which is whbllyremoyab e although I such; construction would be less Suitable if applied to afcylind ri'cal boxtf The superimposed blades desirably are Separated from each other by intermediate layers of water-repellan't material, such as impregnated paper. 1 These layers, when a cylindrical b is empl ed, desirably" are of circular form.

' out of contact at all times.

provided with substantially circular ends and the cylindrical wall 2 of the box desirably is complementary to the circular ends of the blades and ofa slightly greater diameter than the maximum length of the blades. By reason of this construction the circular Wall of the box is adapted to engage the ends of the blade in such a manner as to maintain the blades in parallelism even though they rotate within the box and also acts to prevent the edges from coming into contact with the Wall of the box.

The box can be made of any suitable material and provided with any desired ornamentation.

A box of the character described with a predetermined number, such, for example, a dozen blades, is sold as an article of manul/Vhen it is desired to use a blade the lid 4 of the box is opened, as illustrated, and the finger of the operator inserted through the aperture 9 in the bottom thereof a sutficient distance to lift the superimposed blades until the uppermost blade lies slightly above the edge of the surrounding wall 2 of the box. The uppermost blade can then be slipped readily from the box and used. After the blade has been used it should be returned to the box at the bottom of the pile of superimposed blades. This can be done by op'ening the lid 7 of the bottom of the box and inserting the blade beneath the pile of blades therein. Of course, the separating member can be removed from the box at the time the blade is removed, and inserted in the bottom of the box before the used blade is returned to it, thus maintaining the blades By thus, each time, removing the uppermost blade for use, and after use inserting the same beneath the pile of blades remaining in the box, each blade is given a period of rest suflicient to improve by lying.

In Fig. 3 a modified construction is illustrated in which the receptacle or box is of general rectangular form, the side walls 10 and'll being parallel to the edges of the blades and the end walls 12 complementary to the circular ends of the blades. In this construction, however, the blades desirably are provided with recesses 13 centrally of their ends and the end walls 12 of thebox arepreferably provided with indentations 14 complementary to'the recesses 13 in the ends of the blades.

The recesses in the blades when engaging the inwardly projecting indentations of the wall prevent sufiicient lateral movement of the blades to enablethe edges thereof to engage the side walls 10 and 11 of the receptacle. In this construction care must be taken to prevent the edges of the blades from engaging the walls 10 and 11 of the box when the blades are removed or inserted. In this type of construction a sliding lid or a wholly removable lid may be employed.

In this construction a lid 15 is hinged to the'top of the box, preferably about midway of the length thereof, and a corresponding lid 16 is similarly hinged to the bottom of the box. The bottom of the box desirably -is provided with an aperture 17 for the intively to the top 18 and bottom 19. The lids are provided with

complementary side flangesv

23 and 2 1 and overlapping

end flanges

25 and 26 either adapted to, or having means to clamp the same together when they are swung into closed position, as illustrated in dotted linesin Fig. 4.

Cheaper commercial packages'canbe constructed by providing the box with one lid only. This will, however, necessitate the removal of the'entire pileof blades when a used blade is to be inserted in the proper order above described.

The embodiments of the invention disclosed herein are of an illustrative character and are not restrictive. It will, therefore, be understood that other forms of boxes may be employed and that various changes in construction and arrangement of parts may be made within the spirit and scope of the following claims.

Having thus described the invention, What is claimed as new, and desired to be secured by Letters Patent, is:

1. A box for a plurality of like superim posed blades comprising a casing to enclose said blades having means to engage the ends of the. blades acting to prevent engagement of the edges thereof with thewall of the box and means for permitting the removal of the blades in predetermined succession from one side of the box and the insertion of the blades in the same succession into the other side of the box.

2. A box for a plurality of like superinn' posed edged blades comprising a casing having a base, a surrounding side wall formed to engage the ends of the blades and acting to prevent engagement of the'edge or edges of the blades with thesurrounding' wall and a top having a hinged lid section to permit the removal of said blades successively for use, and an aperture'in the bottom beneath said lid.
