Specification of Letters Patent.

Patented Feb. 2a, 1914.

Application filed June 24, 1912. Serial No. 705,609.

To all whom it may concern:

Be it known that I, JOHN S. HEDDEN, a citizen of the United States, residing at Newark, in 'the county of Wayne and State of New York, have invented a new and useful Egg-Tray, of which the following is a specification.

This invention relates to a collapsible carton.

The principal objects of the invention are to provide an improved form of collapsible box and to shape the blank from which the box is formed in such manner as to effect a marked economy in material, at the same time preventing any waste or scrap mate rial, by arranging for the formation of a number of blanks from a single strip or web of material, all of the material being used.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made with in the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawing, forming part of this specification,-

Figure 1 is a plan View of an elongated strip or web of paper or other material, the ends of the strip being torn away, the strip showing one whole blank and the end portions of the two adjoining blanks; Fig. 2 is a perspective view of one of the blanks, after it has been cut and partly folded into the form of a box; Fig. 3 is a similar view showing part of a box after it has been completely formed and then collapsed; Fig. l is a perspective view showing a complete carton in expanded condition; Fig. 5 is a similar view showing the carton collapsed.

The blanks for forming the boxes of the present invention preferably are cut or stamped in any suitable manner from an elongated web or strip of paper as indicated in Fig. 1, in which one whole blank is indicated at the center and the end portions of two other blanks on opposite sides thereof.

In forming the blanks, the web or paper is cut on the full lines in Fig. 1 and then folded on the dotted lines.

Referring to the complete blank in Fig. 1, the reference numeral 1 indicates the bottom of the box which is defined by the dotted fold lines 2 2 and 3-4. Connected with the ends of the bottom 1 are bottom flaps or ends 5-5, the rear corners of which are cut away on the curved lines 66.

The back or one side of the box is indicated by the numeral 7, and is defined in the blank by the dotted lines 3-8 and 9-9. The back 7 is formed at the ends thereof with back flaps l0-10 which are arranged preferably as indicated in 1, that is to say, the back flaps 10 preferably are drawn out into pointed ends. By an examination of Fig. 1, it will be seen that the cut away portions between each back flap 10 and each bottom flap 5 is of the same shape as the back flap 10, and in forming a plurality of blanks the back flap 10 of the left hand blank, shown in Fig. 1, is cut out of the space between the back flap 10 and the bot tom flap of the middle blank. Similarly, the back flap 10 of the right hand blank in Fig. 1 is cut out of the space between the back flap 10 and the bottom flap 5 of the middle blank. The reference numeral 11 indicates the top of the box which is defined by the dotted line 8, line 12, and side lines 13-18. The top flap is indicated by the numeral 14-, and as shown best in Figs. 3 and 1, this top flap 1 1 is adapted to be tucked down inside the front of the box. The ends of the front flap 14, as indicated in Fig. 1, preferably are cut away at the corners, as indicated at 1515. The front or other side of the box is indicated by the with diagonally extending crease lines 20-2O adjacent the ends thereof, and each of the back flaps 101O of the complete blank, shown in Fig. 1, and

back flaps

10 and 10 of the two adjoining blanks, shown in F ig. 1, is formed with a crease line 21.

It will be observed that the three blanks shown in Fig. 1, are cut out of an elongated strip of material without wasting any of the paper and that consequently there is a marked economy in material.

In forming a box or carton according to the present invention, a complete blank, such as shown in Fig. 1, is employed. The bottom fiaps 5 are folded upward on the dotted lines 22; the front 16 is folded upward on the dotted line a; and the front flaps 1818 are folded rearward on the dotted line 17, so as to overlap the bottom flaps 5 on either the inner or outer sides thereof, whichever is desired. The back 7 is folded upward on the dotted line 3; the back flaps 10-10 are folded forward, preferably on the outer sides of the bottom flaps 5 and the front flaps 18. The portions or tabs 10' of said back flaps 10, that is, the portions outside of the crease lines 21, are then riveted or otherwise secured to either the adjacent bottom fiap 5 or front flap 18, or to both, as indicated by the staples 23, in Fig. i. The top 11 is folded on the dotted line 8 and the top flap 1% is folded on the dotted line 12, thereby producing the complete box, as shown clearly in Fig. a.

After the complete box has been formed, said box is collapsed as indicated in Figs. 3 and 5, by folding the front 16 backward and downward, on the crease lines 2020, and then folding the ends of the box inward on the crease lines 21.

It will be observed that the crease lines 21 constitute the sole crease lines at the ends of the box, and that the bot-tom flaps 5 and front fiaps 18 are not formed with crease lines, these flaps folding snugly against the bottom of the box without the use of crease lines.

In using the carton as an egg box, the partitions shown in Fig. 4 are inserted therein.

Particular attention is directed to Fig. 4, wherein it will be noted that the uncreased fiaps or ends 5 are provided with portions extending beyond the fold lines 21 of the fiaps 10, so that these projecting portions may swing flatly against the flaps 10 when the ends or fiaps 5 are unfolded, to limit the outward movement of the flaps 5. This is of importance, in connection with the cut away portions 6, which permit the ends of flaps 5 to fold without creasing. Thus, the ends or flaps 5 and the flaps 10 are provided with cotiperating uncreased portions adapted to swing flatly together when the carton is unfolded, to prevent excessive movement of the ends or flaps 5. lVhen the partitions are placed within the carton, it will be obvious that the sides and ends of the carton will be locked against inward movement, the ends being prevented from bulging or moving outwardly excessively, due to the contacting portions above described.

Particular attention is also directed to the fact that those corners of the cut away flaps 1O adjoining the ends 5 are cut on ogee or compound curves, or may be said to be out on reversely extending lines, inasmuch as the lines on which the said corners are cut, may be reversed so as to extend in precisely the same direction. The term reversely extending lines is thus conveniently employed for describing that line on which the corners of the flaps 10 are cut, adjoining the ends 5, whereby the cut away flaps of adjoining blanks will interfit, as clearly seen in Fig. 1. It will also be noted that the other corners of the flaps 10, or those corners remote from the ends 5, and the cut away corners of the ends are cut on reverse lines, whereby with the peculiar cut of the corners of the flaps adjoining the ends 5, the openings between the ends and flaps 10 will be precisely of the same contour as the flaps 1O themselves.

What is claimed is:

l. A collapsible carton blank comprising a bottom having sides and ends, the sides having flaps attachable to the ends, one side having a top provided with a flap, the corners of the flaps of that side having the top being cut away, and the adjoining corners of the ends being cut away, those corners of the cut away flaps adjoining the ends being out on reversely extending lines, and the other corners of the said flaps and the cut away corners of the ends being cut on reverse lines, in order that the opening between the ends and the cut away flaps will be precisely of the formof the cut away flaps.

2. A collapsible carton blank comprising a bottom having foldable sides and ends, one side having a foldable top and foldable flaps to cooperate with the ends, said flaps having diagonal fold lines forming tabs attachable to the ends, the other side having foldable flaps attachable to the ends, the adjoining corner portions of the first mentioned flaps and ends and the other corner portions of the first mentioned flaps being cut away, those corners of the cut away flaps adjoining the ends being cut on reversely extending lines, and the other corners of the said flaps and the cut away corners of the ends being cut on reverse lines, in order that the openings between the first mentioned flaps and ends will be the same as those of the first mentioned flaps, the ends having portions to project beyond the fold lines of the first mentioned flaps when the In testimony that I claim the foregoing as tabs are attached to the ends to swing my own, I have hereto affixed my signature against the first mentioned flaps when the in the presence of two Witnesses.

ends are unfolded, so as to limit the move- JOHN S. I-IEDDEN. ment of the ends, the cut away portions of the ends permitting the ends to fold Without creasing.
