Application July 21, 1941, Serial No. 403,261

1 Claim.

The general purpose of my present invention is the same as that of the one now on file. The specific purpose of the present invention is to provide simple means for forming the package of blades into a unitary carton that is made and formed of the covers of the package, without the use of extraneou fastenings.

A further purpose of the present invention is to comprise the package of front and back cover sheets and intermediate separator sheets between each of which I place a blade that is to be packaged into a carton.

I have found that I may make a package by forming a plurality of slits in the back cover sheet and a plurality of tongues in the front cover sheet. The respective tongues and. slits are so formed as to be placed in registry with each other so that the respective tongues formed from the front cover may be made to pass through slits that are disposed within the blades and slits that are placed within the intermediate separator sheets, so that a completed carton may be assembled and secured together by passing the tongues through the slits that are disposed within the blades and within the intermediate sheets and through the slits disposed in the back cover. This forms a carton that is not increased in total depth, and yet comprises the packed carton in such a manner as to facilitate the merchandising of the carton, as a carton without other means being employed for securing the same together.

A still further means for forming the carton, consists in first assembling the package of the desired size and number of units, and then sealing the carton by applying a sealer medium to the ends and to the edges while in a fluid state. I have found satisfactory results may be secured through the use of rubber cement, glue, or through the use of any other one of the many substances that may be employed for this purpose.

With these and incidental objects in view, the invention consists in certain novel features of construction and combination of parts, the essen- -tial elements of which are set forth in the appended claim, and a preferred form of embodiment of which is hereinafter shown with reference to the drawing which accompanies and forms a part of this specification.

In the drawing:

Fig. I is a perspective front view of a carton of blades. The carton is made up of a top and a bottom member and intermediate members with the respective members and blades being held together by tongues that are formed fromthe top unit.

Fig. II is a side view of the top unit shown removed from the carton and illustrating the tongues disposed at right angles to that of the main body of the top unit.

Fig. III is a perspective front view of a carton of holder members and blades with tabs being disposed at one end of the respective top and bottom and intermediate members between each of which a blade is placed. The tabs are each progressively longer from the top to the bottom of the carton.

Fig. IV is a side view of the top unit shown removed from the cartonjand illustrating the tongues disposed atright angles to that of the main body of the top unit.

Fig. V is a perspective front view of a carton of blades with the top, bottom and intermediate members between which the blades are disposed being of different lengths.

Fig. VI is a side view 'of the top unit shown removed from the carton and illustrating the tongues disposed at right angles to the main body of the top unit. In this view the o'utwardportion of the tongue adjacent the end is shownas being bent at right angle to the main'portion of the tongue.

Fig. VIIis a perspective front view of ,acar-J ton of blades. as being held to ether through the use of a strip of material that passes through slits that are disposed in the units of the carton and through corresponding slits that are disposed within the blades.

Figure VIII is a side view of the binding strip shown removed from the carton. Inthis view the 3 strip is bent adjacent its ends to permit the passage of the up-turned ends through the blades and separators. A second bend near the ends of: the strip is indicated by the broken-linefigures' and illustrates the final form of the strip as attached to the assembled package.

Fig. IX is a perspective front view of a carton of blades that are initially assembled and that are then bound together and sealed through the use of a binder that is applied while fluid.

Like reference characters referto like parts throughout the several views.

In the forming of a carton of blades and more particularly of razor blades, it is essential that the respective blades be separated from each other and from direct exposure to the atmosphere to prevent oxidation of the metal of the blade. It is also essential that the carton of blades be In this view the carton is shown confined to a minimum of space, because the carton of blades is usually carried by the user as a carton. It is also essential that the user be able to procure the blades one at a time, and that he be able, with a minimum of effort, to secure the blades from the carton one at a time. Through competition, it is now necessary that the carton and the blades comprising the same, be produced at a minimum of cost.

I have found that by making the carton of a top and bottom member, with intermediate filler members beingemployed and the placing of a blade between each of the top and bottom and intermediate members, that a carton can be produced at a minimum of cost. The cost is further reduced if the members of the carton other than the blades are made of a material that prevents the corrosion of the blade. By making the carton as here outlined, the individual wrapping of each of the blades, as is now generally done, is not necessary.

In the making of my carton, I use a top member I. I form connecting tongues 2 from the top member I by punching the respective tongues from the main body of the top member I, leaving the respective tongues attached to the body at one end of, the tongue. The location of the tongue is such that it will register with a slit that is disposed within the body of the blade that is to be packaged.

I may make'the carton as illustrated in Fig. III and in Fig. IV. When so made, the top member 3 has'a plurality of tongues 4 formed integral with the body I. I have here shown a pulling tab 6 disposed at one end of the top member 3. Eachof the intermediate members disposed below the top 3 and the bottommember of the carton, each have pullingtabs associated with the same end of the carton, as, illustrated at 6 to H inclusive, with the respective tabs disposed below the top tab 6 being longer than the one disposed therebelow to facilitate engaging the same with the thumb or finger nail. The tongue when formed, leaves a hole immediate the tongue. When the carton is made, as illustrated in Figs. I to IV inclusive, the length of the tongue is the thickness of the carton, less the thickness of the top member from which the tongue is punched. A slightly modified form of carton may be madeas illustrated in Fig. V and in Fig. VI. When so made, the top member of the carton l2 has tongues f3 and I4 punched therefrom; thus leaving holes I! and I8 adjacent the base end of the tongue. .I have shown in Fig. VI, tongues that are longer than the depth of the carton, in order that the tongue adjacent its outer end,

may be bent at'right angles to secure the carton,

in a state of homogeneity, when the tongues are so bent and so arranged. While in Fig. III, I showed tabs disposed at one of the ends of the carton to aid the removal of the respective members between Which the blades are placed. I have shown the members for covering the blades in Fig. V as being of different lengths, as illustrated at 23, with the ends being arranged in stepped formation. It will be readily apparent that the tabs may be placed on either end, or at both ends of the carton, or that the tabs may be arranged in stepped formation, either way from the center, to thereby lessen the overall length of the carton. The stepped formation, as shown in Fig, V may also be arranged at either end, or at both ends of the carton. The longest of the members may also be placed midway between the sides and then arrange the adjacent ones outward at either side in stepped formation. In Fig. VII I have shown the carton l 9 made in the manner as outlined above and I have secured the same together with a strip 2!). The strip is made of a width of the length of the slots in the blades to be packaged. Similar slots are made in the top, bottom and intermediate members, through which the strip material passes to act as a binder for securing the same together. I make the legs 2i and 22 suiiiciently long to pass through the carton and to permit the legs being bent adjacent their ends, to act as a binder for securing the carton and its component units together in a carton.

I have made some cartons as indicated in Fig. IX. When so made, I assemble the carton of blades, top, bottom and intermediate members together and then apply a binder agent to the edges and to the respective ends of the carton. The binder agent is applied while in a fluid state and that is quick drying in character. Some rubbe'r cements, glues, pastes, and many other binding agents may be used to produce a carton that is satisfactory and that will cost a minimum.

While. the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is understood that it is not intended to confine the invention to the embodiment herein shown and described, as it is susceptible of embodiment in various forms, all coming within the scope of the claim which follows.

What I claim is:

A razor-blade package comprising, a plurality of razor-blades and one more than an equal number of longer and wider water-resistant paper separators arranged in surface contacting alternate disposition to provide extensions of the separators beyond all edges of the razor-blades, binding means to secure adjacent separators in sequentially detachable relationship extending through the razor-blade apertures to bind the separators in mutually contacting relationship at the middle areas thereof, and cement means to bind and seal the edges of the separators in mutually contacting relationship.
