July 7, 1942. F. w. BRODERICK CARTON Filed Oct. 10, 1939 BY Mi, %ORNEY has .ly is I coon w. Broderick, Newnngmon, N. m, assign or to olds Metals Com, t g, Va, a corporation of Delaware 1 Application ember t, rose, Ser No. seam c on (emcee-n).

is a continuation in portal my patent application, Serial No. 233,955, filed Gctober 8, 1938, for Carton, and contains divisible subject matter therefrom.

invention relates to new and imp cartons for packaging merchandise and particularly relates to such cartons formed from a one piece integral blank by simple die-cutting and die-sco methods, and provided, if desired, with ection cut outs, in which latter event, the carton may be provided with an exterior wrapp oi Cellophane or a like transparent wrapping medium.

Heretofore, somewhat generally similar cartons have been suggested, but these have been either dimcult or expensive to manufacture, or diiiicult to assemble, or dificult to ship, or have not been attractive. Therefore, it is an obiect of my invention to form a simpleknock-down collapsible carton, with an opening through which the goods may be inspected, from 9. preferably integral blank, which is easy and inexpensive toassemble the same-from a single sheet of material by simple die-cutting and die-scoring operations, and to also reduce. the cost 0! assembling the cartons because of the unique construction or the blanks and because gluing operations are not required.

Other'objects andadvantages of the invention will become apparent when taken in connection v with the'accompanying drawing.

My invention can be readily understood irom the accompanying drawing, which is set forth merely for purposes of illustration, and is not to be deemed as limiting the scope of the invention, and it is apparent that various modifications and changes of the combinations of elements illustrated may be made without departing from the spinimtsof my invention as defined in the appended scored blank which may be employed to form one type of carton 'embod my invention;

Fig. 2 is a perspective view of the blank shown in Fig. 1, partially assembled, and is so shown for purposes of clarity; v

Fig. 3 is an end view oi the blank shown in Fig. 1, partially assembled, and is so shown for purposes of clarity;

Fig. 4 is a lateral cross section of the carton, when assembled;

Fig. 5 is a. longitudinal cross section of a carton formed from the blank shown in Fig. l, which additionally includes an outer Cellophane wrapper and which also shows a toothbrush with the said carton;

Fig. 6 embodies an alternate form of my'invention, particularly adapted for use with orange sticks and includes an integral holdingmeans for larly adapted for packing one or more toothbrushes, and includes integral holding means for such brushes in the base of the carton.

In Figures 1-5, a carton it! is preferably made from a one piece die-cut and die-scored integral blank 82, and will normally be provided with a rounded top portion i4, and triple overlying bottom portions i6, i8 and 2i Top portion M will ordinarily be provided with a cutout opening such as 22.

Outer bottom portion, identified as It, will usually be provided at each end with an end locking flap, identified as 26, and each locking flap 24 will have upon its outer end an end compressive flap identified as 25. The outer edge portions of end flaps 26 will ordinarily be slightly curved as indicated. Also, bottom panel portions l6 and It will normally be slighly indented as indicated at 28, so that panel members it and i8 may be folded one over the other and so that the end locking, flaps may be-inwardly and upwardly bent, without bulging at the ends of the carton, and

' assume a position in the-horizontal plane (see' In.- the accompanying .dra, wherein like reference numerals are used to designate corresponding parts throughout the several views:

Fig. l is a plan view 0! a die-cut and die- Flg. 5), to lock the triplicate bottom panels a stiff rigid assembly. r In assembling the carton, top portion It will be compressed into a curve while the looking flaps 14 are pressed in the position shown in Fig. 5

members l4, l6, l8 and 20, as well as

members

24 and 26, are hingedly and swingably connected by means of score lines, such score lines being identified generally as 34. It will also be noted that panel member I6 might be eliminated entirely with the result that the structure would be less rigid, having only two panel members in the base rather .than three.

members in the blank, in Fig. 1, namely, panel In Fig. 6 there is illustrated a particular form oi carton 36 adapted for merchandise such as orange sticks, wherein the base panel 16 is provided with 2 upswinging hinged tabs identified as 38, which tabs are providedwith openings 40 to accommodate and hold the merchandise in fixed position. The tabs 38 are formed by simple diecutting and die-scoring operations, at the same time that the stamping operations are completed in respect to the carton body.

Another form of my invention, shown in Fig. 7, carton 42 is provided with a panel member l6 which is die-cut laterally in its central portion and the respective inner end portions 44 of the two resulting panel members 46 are provided with slots 48 to accommodate merchandise such as the toothbrush 50, indicated in position in the figure.

Cartons as described above have had wide commercial sale when made from light cardboard stock covered with a metallic foil such as aluminum foil. Since the shape of compressive end members 26, upon the outer edges, determines the curve of top portion I4, it is obvious that cartons embodying my invention may be made in various forms. Also, auxiliary locking means may be utilized to. firmly hold the base portion together and the compressive end flaps 28 in position, but these will normally not be utilized, particularly if an outer Cellophane wrapper is used. If desired, tabs may be provided on members 26 to aid in opening the package.

Also, it is possible to fill the openings 22 with transparent sheet material, thus providing a window, such as a Cellophane window.

It is obvious that variations may be practiced in respect to my invention above described, and therefore reference should be had to the appended claims which define the scope of my invention'.

Having described my invention, what I now claim is:

1. Inan elongated carton, formed of a flat ioldable one-piece blank, a top member and overlapping bottom members, each of which is substantially equal in size and which overlap one over the other for substantially their entire area, a single end turn-back locking flap on each end of the lower of said bottom members, adapted to lock over the end of the upper bottom member, a single end compressive flap at the end of each of the locking flaps, said end compressive flaps adapted to form end walls for the carton and to tension against the top member and to maintain the same in position.

2. In an elongated carton formed oi a flat foldable one-piece blank, a top member and overlapping bottom members, each of which is substantially equal in size and which overlap one over the other for substantially their entire area, a single end turn-back locking flap on each end of the lower of said bottom members, adapted to look over the end of the upper bottom member, a single end compressive flap at the end of each of the locking flaps, said end compressive flaps adapted to form end walls for the carton and to tension against the top member and to maintain the same in position, and adapted to frictionally engage said top member.

3. In an elongated carton formed of a fiat foldable one-piece blank,'a top member and overlapping bottom members, each oi which is substantially equal insize and which overlap, one over the other for substantially their entire area, a single end-turn-back locking fiap on each end of the lower of said bottom members, adapted to look over the end of the upper bottom member, a single end compressive flap at the end of each of the locking flaps, said end compressive flaps adapted to form end walls for the carton and to tension against the top member and to maintain the same in position, and said end locking flaps adapted to maintain the overlapping bottom members in fixed relation.

4. In an elongated carton, formed of a flat foldable one-piece blank, a rounded top member providing a top portion and side walls, overlapping bottom members, each of which is substantially equal in size and which overlap one over the other for substantially their entire area, an end locking flap upon each end of one of said bottom members, and an end compressive flap at one end 01' each of said locking flaps, said compressive flaps adapted to tension against the top member and to maintain the same in rounded form, and to irictionally engage the same.

5. A carton as defined in claim 4 which includes apertures in the rounded top member, permitting inspection of goods within the carton.

6. In a carton, formed of a flat toldable onepiece blank, a top member, triplicate overlapping bottom members all lying in the same plane, each of which is substantially of equal size to the other and'each of which overlap one another for substantially their entire area, locking members upon each end of the lower of the triplicate bottom members adapted to hold the-triplicate bottom members together, and compressive end members hingedly connected to said locking members adapted to tension against the top member and to shape the same.
