' Sept. 6, 1932. F. D. WILSON CARTON Filed May 8, 1929 2 Sheets-Sheet 2 Patented Sept. 6, 1932 UNITED STATES FRANK D. WILSON, 01 OAK PARK, ILLINOIS qan'ron Application filed May 8, 1929. Serial No. 361,298.

This invention relates to containers, and more particularly to a carton for packing eggs. It has for its principal object to produce a simple, inexpensive and practical paper container or carton in which the contents may be sealed or secured against removal and substitutes without first mutilating the carton or opening a specially prepared portion of the outer casing.

The invention has for its further object to produce a novel structure whereby a portion may be removed from its outer wall or casing without unduly weakening or destroying the container. 1

Other objects and advantages to be attained will more fully appear in the following description:

In the accompanying drawings forming part of this specification, and illustrating the preferred embodiments of the invention,

Fig. 1 is a perspective view of a container comprising an open-ended, rectangular, tubular, outer casing with a cellular insert or filler, and having provision for opening a major portion of its top wall and corner portion of the adjacent side wall.

Fig. 2 is a transverse section on line 22 of Fig. 1, the severable portion of the outer casing being shown in open position.

Fig. 3 is a perspective view of a modification of the structure shown in Fig. 1.

Fig. 4: is a perspective, view of a further modification, the outer casing being closed at its ends, and having two removable portions in its top wall.

Fig. 5 is a section on the line 55 of Fig. 4; and V Fig. 6 is a perspective view of a further modification.

Referring now more particularly to Fig. 1 of the drawings, in which is illustrated a preferred and practical embodiment of the invention, the numeral 10 designates a rectangular, open-ended, tubular outer shell or casing of heavy paper or cardboard, in which a filler 11 is inserted, said filler preferably comprising a plurality-of individual cells or receptacles 12 for the respective eggs 13.

lihe filler 11 may be secured against removal after insertion in the casing 10 by .engaged with thethe finger nail and drawn any suitable means, mechanical or otherwise, but forpractical purposes and economy it is preferably secured by an adhesive substance which may be applied just prior to the insertion of the filler, said adhesive being designated by the numeral 14, and shown more clearly in Fig. 2 of the drawings.

The top wall 15 ofthe outer casing is preferably weakened by scoring or providing a series of closely arranged perforations along the transverse lines 16 at the ends of the carton, said lines of scoring ,or perforations extending entirely from side to side of the carton, and for a slight distance from the top wall 15 downward on the front wall 17 as at 18, said portions 18 being connected at their ends by a line of scoring or perforations 19 paralleling the adjacent corner portion of the carton. Preferably, the middle portion of the line 19 is slitted arcuately, as at 20, thereby providing a segmental portion or tongue 21.

By the foregoing construction, the contents are normally sealed or held securely within the carton, and cannot be removed without mutilating the carton or properly opening it in the-manner provided. When it is desired to remove the contents, it is an easy matter to insert a knife blade or other relatively sharp implement through the slitted portion 20 in the side wall 17, and then sever said side wall and the top wall 15 along the lines 19, 18, and 16, respectively, whereupon the major portion of the topwall 15 may be swung upwardly from the rear corner 22. Should a cutting implement not be conveniently at hand, the tongue portion 21 in the region of the arcuate slit 20 may be readily outwardly or it may be pressed inwardly with the end of the finger, and by careful manipulation with the fingers, the outer casing 10 of the carton may be severed along the lines of perforations 19, 18 and 16, respectively.

Should it not be desired to remove all of the eggs or other contents from the carton at one time, the severed top wall portion may be closed, as the carton is still held intact by the transverse end portions 23 remaining as integral cross braces for the side walls after the major intermediate portion of the top wall 15 has been severed.

a considerable extent even after the carton has been opened as above set forth.

In Fig. 3 the structure is substantially the same as that shown in Fig. 1, except that the transverse scoring or lines of perforation 16 do not extend down into the side wall of the carton, but they are connected by line 19 extending longitudinally of the top wall 15 at the middle thereof, and said line 19' being slitted for a short distance midway between its ends as at 20. In this structure the stay bars 23 are provided precisely the same as in Fig. 1 when the carton is opened, but the top wall 15 opens in two sections 2 1 and 25 instead of a single flap as shown in Fig. 1.

In Fig. 4; the carton is closed by end walls 26, and the filler, as shown more clearly in Fig. 5, is somewhat different from the filler 11 hereinbefore described, in that the cells of the filler 11 are conformed to the contour of the eggs, whereas in the present modification the respective compartments 12 are rectangular and are provided by crossed longitudinal and transverse partition members 27, and there being also provided pads 28 having concaved seat portions 29 for the respective eggs. In this modification, also, the filler may be either fastened or placed loosely in the carton, as may be desired, as the ends of the carton are sealed.

Instead of scoring or perforating the top wall 15 of the outer casing of the carton transversely and longitudinally as in the two hereinbefore described structures, said top wall is provided with two sets of rectangular lines of scoring or perforations 30, one line of each set being preferably slitted as at 31. To remove the contents of this last described carton, it is necessary to sever the two panels 32, 33, and they may be entirely removed or, if severed only along two opposite side lines and one cross-connecting line, the respective panels may be swung upwardly on the unsevered line as shown in Fig. 5 of the drawings, and indicated by the numeral 33'. This structure affords an additional cross brace 23 and the upper corner portions, front and rear of the carton, are further stiffened by the narrow marginal portions 34 and 35 remaining after severance of the two panels 32 and 33. A further modification is shown in Fig. 6, wherein the end walls 26 are omitted, in which case, of course, the filler 11' must be cemented or otherwise fastened within the tubular outer casing 10 as in the modifications shown in Figs. 1 to 3 inclusive. In this modification the top wall 15 is scored or perforated as at 30 to provide a single removable panel 36.

Obviously the structure admits of considerable further modification without departing from the spirit and scope of the invention as defined by the amended claims.

The invention, therefore, is not limited to the specilc constructions and arrangements shown in the accompanying drawings.

What I claim as new and desire to secure by Letters Patent is:

1. A carton of the character described, comprising a substantially rectangular, openended tub'ular case and a compartmental filler inserted endwise and retentively secured in said case, one side wall of said case having opening panel portions and fixed transverse bracing panels, said panels being defined by transverse lines of closely arranged perforations adjacent the opposite ends of the carton, and a central longitudinal line of like perforations connecting said transverse lines of perforations.

2. A carton of the character described, com prising a substantially rectangular tubular case, and a compartmental filler inserted endwise and retentively secured in said case,

one side wall of said case having opening panels and transverse fixed panels at its opposite ends, the defining lines of severance between said panels being perforated throughout the general extent thereof, and a portion of the lines being slitted.

In testimony whereof I have signed my name to this specification.

FRANK D. WILSON.
