11 Claims.

My invention relates to paper containers open at one end and particularly to the construction.

for closing the open end of the container.

An object of the invention resides in pro- 5. viding a construction in which the closure may be readily stitched to the body of the container by the ordinary stitching or stapling machine.

Another object of the invention resides in providing a construction in which the open end of the container is greatly reinforced. A still further object of the invention resides in constructing the container with a flange disposed upon the exterior of the wall structure of the container and attached at one of its edges to the wall structure and free from the wall structure throughout the remainder thereof to permit of inserting the anvil of a stitching me.-

chine between said flange and the wall structure of the container to secure the closure thereto.

Another object of the invention resides in constructing the body flange integral with the wall structure of the container and in folding the same back from the upper edge of the wall structure and upon the exterior thereof.

A still further object of the invention resides in constructing the wall structure of the container tapered, the flange thereof being disposed at the larger end of the container to cause the freeedge of the flange to be spaced from the wall structure of the container to facilitate the insertion of the anvil of a stitching machine therebetween.

A feature of the invention resides in the construction of the container so that the flange may be doubled back upon the body without breaking the stock from which the container is constructed.

An object of the invention resides in constructing the body of the container from a blank of paper scored transversely to provide 'a'number of side walls and scored longitudinally near the ends of the side walls to provide a flange foldable upon the exterior of the wall structure of the container.

Another object of the invention resides in constructing the length of the flange equal to the perimeter of the body of the container at the end thereof to which the flange is attached, and in constructing the wall structure at predetermined intervals with gathers to take up the excess material occasioned by the disposition of the flange upon the exterior of the wall structure of the container.

A feature of the invention resides in providing 5 slits in the blank of the container body, extending along the longitudinal score line and inter-' secting the transverse score lines, said slits permitting of the formation of gathers upon the interior of the wall structure in the folding up of the container blank. 5

Other objects of the invention reside in the novel combination and arrangement of parts and in the details of construction hereinafter i1- lustrated and/or described.

In the construction of containers from paper a considerable difliculty has been encountered in devising a container inexpensive in construction and provided with a cover or closure which could be easily and quickly applied thereto. The present invention provides a container in which the closure may be attached to the body of the container-by wire stitching-or stapling.

My container comprises a body in open at its ends which is closed at the lower end by means of a bottom It and which is adapted to be closed 40 at its upper end by means of 'a closure l2. The body I0 is preferably constructed tapered in form so that the contents thereof may be easily removed from the container and is most advantageously constructed polysided, preferably 45 with a number of sides greater than four. In the drawings a container having eight sides has been shown, though it can be readily comprehended that any number may be used. The various partsof the container will now be ie-' scribed in detail. I

The parts of my improved container are constructed of any suitable kind of paper board, flber or other similar material and are secured tog ther by stitching or stapling. The body ill is 3,

constructed from a blank l3 illustrated in Fig. 2 which is elongated and arcuate in form. Blank I3 is scored transversely along lines I4, I 5, l6,

l1, l8, I9, 20, and 2| and is sheared at its ends along lines 22 and 23, all of said lines converging at a single point, not shown in the drawings. The blank is further sheared along an irregular line 25 which is similar to the arc of a circle having as its center the center of convergence of the score lines and shear lines but which consists of a number of rectilinear parts 26 which are at right-angles to the median lines between the shear line 22 and the various score lines l4 to 2|. The blank is further sheared along a line 21 similar to the line 25 which bounds the blank at the upper end thereof. In addition to the score lines l4 to 2| the blank is constructed with a longitudinal score line 24 which is parallel to the shear line 21 and which intersects the score lines l4 to 2|. The blank is also constructed with a number of short slits 38 which extend along thescore line 24 and which intersect the score lines l4 to 28 inclusive. By means of the various score lines and shear lines, the blank is formed with tapered side walls 28, 29, 30, 3|, 32, 33, 34, and 35 and an end flap 36 which constitute the wall structure of the container, in addition to a flange 31 which is disposed at the ends of the side walls 28 to 35.

The various score lines in the blank are all formed upon the inner surface of the container. In erecting the container the blank I3 is folded simultaneously along the score lines l4 to 2| inclusive and the score line 24, the flange 31 being folded in the opposite direction to the folds of the walls of the container. This causes the flange 31 to overlie the wall structure of the container upon the exterior thereof. When the parts have been properly folded, flap 36 is stitched to the side wall 28 by means ofstaples 42.

The ends of the flange 31 are telescoped as best shown in Fig. 6. To cause the rim of the container indicated at 40 and formed by the fold of the flange 31 along score line 24 to lie in a single plane, a slot39 is cut in the flap 36 and the flange 31 which slot extends from the free edge 22 of the blank up to the score line 2| and which is disposed medially with respect to the score line 24. This slot is of a width substantially equal to twice the thickness of the paper board or other material from which the container is constructed. This leaves a tongue 4| on the end of the flange 31 which is inserted between the other end of said flange and the wall 28. These various overlapping parts are held in position by means of a staple 43 which passes jointly through all of said parts.

In forming the flange 31 it is necessary to fold the stock in the opposite direction from that in which it was folded to form the various walls of the container. Due to the score lines all being made upon the-interior of the container, such folding causes an accumulation of stock upon the interior of the fold which holds said flange away from the surface of the body of the container and leavesa space 44 between it and the wall structure of the container. In addition, the arrangement of the score lines l4 to 2| inclusive in converging manner causes the flange 31 to further gap with respect to the side walls of the container at the lowermost part thereof. This.

permits of readily inserting the anvil of a stitching machine in between said flange and the wall structure of the container to permit of securin the closure to the container, as will be hereinafter more fully described.

Due to the fact that the length of the flange 31 at its lower edge is only slightly greater than the perimeter of the wall structure of the container and at its upper edge and along the score line 28 is exactly the same length, it becomes necessary to make provision for the surplus stock which is occasioned through the folding of the various parts as described. The slits 38 in the blank l3 separate the flange 31 from the wall structure of the container at the various score lines l4 to 2| inclusive. This permits the Wall structure of the container to buckle or gather at such localities 'as shown in detail in Fig. 5. The surplus stock is indicated in this figure by the reference numeral 63 and takes the shape illustrated in said figure. This gather engages the wall structure of the container and assists in maintaining the space 44 previously referred to between flange 31 and said wall structure.

The bottom ll of the container is constructed from a blank 60 shown in Fig. 4 which is polygonal in form. The blank 68 is scored along lines 46 parallel to the edges thereof and is notched as indicated at 41 to provide a polygonal bottom proper 45 and flanges 48 issuing outwardly there from. These flanges are folded outwardly as indicated in Fig. 1. The bottom II with the flanges 48 folded is inserted into the container through the open end thereof and forced downwardly until the said bottom occupies the position illustrated in Fig. 1. The flanges 48 are then stitched to the side walls of the body ID of the container by means of staples 6|.

The closure for the container is constructed in identically the same manner as the bottom H excepting that the same is of suitable dimensions to fit about the exterior of the flange 31. The closure I2 is constructed from a polygonal blank 50 which is scored along lines 5| and notched at 52 to form a polygonal top 49 and flanges 53 projecting outwardly therefrom. When the closure I2 is to be applied, the same is placed upon the rim 40 of the body of the container and the flanges 53 folded downwardly therefrom. As the flanges are brought into position the same may be stitched to the flange 31 by means of staples 56 which is accomplished by inserting the anvil of the stitching machine into the space 44 and operating the stitching machine while the parts are'so arranged. It will thus be seen that the entire container may be easily and quickly closed and when the closure is applied, the container is permanently closed.

Where exceptionally heavy material is used in the formation of the container, I have found it necessary in order to prevent cracking of the material in the formation of the flange 31 to make provisions for the gathering of a greater amount of the material than could be accomplished by the use of a single score line. In Fig. 7 I have shown a portion of one of the blanks to procure the desired result and in Fig. 8 a detailed view of the structure formed thereby. Inasmuch as the construction shown in this form of the invention is practically the same as that previously illustrated, the description thereof will not be repeated and the same reference numerals will be used to illustrate corresponding parts. In this form of the invention portions of the score lines l4 to 2| adjacent score line 24 are dispensed with and twin score lines 51 used in place thereof which extend up to the slits 38. These score lines the construction illustrated at 63', but consider ably wider and involving a greater amount of stock. Due to the use of the twin score lines, the stock indicated at 58 projects inwardly into the container extending in the opposite direction as compared to the structure indicated at 63. The slits 38 are in such case constructed slightly longer so as to permit of sufficient gathering of the stock to form the construction illustrated without tearing.

My invention is highly advantageous in that an extremely simple and practical construction is provided whereby paper containers may be formed which can be used for the shipment of various commodities and which canjbe closed by the ordinary stitching or stapling machine after the commodities have been placed within the containers. My container can be constructed at an extremely low cost as compared to wooden tubs and similarcontainers. Due to the low cost of my container the same may be discarded after each use, thereby. eliminating the-disadvantage of having to return and recondition the containers for further use. My container is extremely sturdy in construction and will withstand the severe handling and usagewhich containers of this type are subject to. By means of the slits formed along the score line between the flange and wall structure of the container, the surplus stock in the vertical corners of the body is per-. mitted to gather, thereby preventing tearing or breaking of the stock in the formation of the flange. By bending the stock in the reverse manner to form the flange, the flange may be completely doubled back upon the wall structure of the container without breakage. My container is extremely neat and attractive in appearance and fulfills all shipping and transportation requirements.

Changes in the specific form of my invention, as herein disclosed, may be made within the scope of what is claimed without departing from the spirit of my invention. v
