Application December 1a, 1:546, Serial Nanette In the field ofpaper containers, and more especially with respect to milk bottles. there is still considerable to be desired to render them thoroughly practical. The principal objection is that bottles of this type are not sufllciently rugged to withstand the rough handling to which they are so frequently subjected, thereby causing breakages or ruptures which. ruin the containers and thus defeat the essentialobject soughtnamely, that of economy. Other defects reside in the excessive number of parts required to produce a container, accompanied, obviously, by an increased cost of manufacture; they do not lend themselves to economical, large scale production;

they lack the proper contour which makes for easy handling and compact storage.

I have eliminated the aforesaid inherent disadvantages by constructing a bottle from a single sheet of fibrous material, as paper, which is characterized by maximum strength and rigidity; which permits of economical quantity production; and which is fashioned in modern design to expedite handling. packing and storage.

In a general sense, the present invention comprehends a container formed from a rectangular sheet of fibrous material-paper for example which is subjected to double folding in two directions in such manner'as to produce a contraction of the original sheet into a relatively flat form incorporating a stratifled base with manifold flaps extending therefrom which are subsequently deflected upwardly to constitute the body, neck and lip portions. n

More specifically, the invention comprises a rectangular sheet of paper which is folded transversely upon. itself so that one portion overlaps the other portion. The larger portion is then folded rearwardly whereby it extends beyond the 4 Claims. (Cl. 229-3.5)

edge of the smaller portion for a distance equivalent to the overlapof the larger portion. Thereafter the forward and reverse folding operations are repeated with respect to the two portions previously folded, but at right angles to the first forward and reverse folds-presenting a rectangular form of reduced pattern which consists of corner flaps having a single thickness of paper. and medial and intermediate flaps of plural layers of paper, all of the flaps designed to be struck-up from the medial flaps, with the corner flaps creased at their diagonal centers and folded exterlorly of, and hugging. the adjacent intermediate flaps-said flapsthus constituting the body, the upper extremities of which are moulded into a tapering cap-receiving recess.

- As will be seen-in Fig. l, I begin with a rectangular sheet of paper I. which is scored or similarly weakened transversely at equidistantly spaced intervals II. l2, l3 and I4, and at right angles thereto-see II, I, I1, and I8, so that the scorings intersect centrally to form a miniature checkered design It, in the present example, consisting of nine squares II. To further facilitate folding, the corners 2i, 2!, 23 and 24 of sheet II are diagonally scored at 2!.

With the scored delineations serving as a guide,

the next step consists of folding the sheet forwardly along line ll-see Fig. 2-and reversely at It. Then with the portions folded as indicated at the front edge of Fig. 3, the sheet is folded forwardly along line H at right angles and then reversely at I, also illustrated in Fig. 3. Succinctly, each of the preceding steps involves double folding operations-forward and reverseand one set of folding operations transpires at right angles to the other set, with the result that If form a perfect rectangle of reduced pattern and incorporating a multi-ply bottom 28 with nine superimposed layers plies (Fig. 7)- or all of the triple layered intermediate flaps 21, as will be observed in Fig. 4. Thereupon, the corner flaps are folded at their diagonal scoring lines 25 and caused to assume a triangular shape. Subsequently all of the flaps are struck-up vertically from the bottom, the intermediate flaps or plies constituting the inner side walls of a square container body and the comer flaps radiating therefrom, as shown in Figs. Band 6.

The corner flaps are then wrapped spirally and anti-clockwise, about the side walls (Figs. 8 and 9) and the container takes on the form exhibited in Figs. 10 to 12 inclusive, wherein in addition to the fortified base, it will be observed that the side walls assume a multi-ply construction and that the thickness thereof is progressively increased to impart further strength and to provide an abundance of paper at the upper extremity just where it is required, that is, to permit crushing and molding of the paper by suitable com pression in the form of a tapered neck 23, with shoulders 29 reinforced by the ribs 30, and a lip 31 having an annular recess 32 to receive a suitable cap-all of which latter portions are of .ample thickness of stock to eflectively resist rough handling.- (Figs. 13-16.)

The sheet from which the container is manufactured is preferably impregnated with a'desirable waterprooLmaterial, asparafline. This serves to make the folds adhere to each other, as well as to impart rigidity to the bottle, in its entirety.

The ultimate container also possesses strength in the maximum degree. The square shape with flat sides makes this bottle easier to gripand hold; the short neck insures easy pouring like a pitcher, with no gurgling and practically no drip- D1118; these bottles pack square, requiring 43% less room in a given space than the old style round bottle; and they may be manufactured in mass quantity production at a cost of only a few pennies each, which permits of their being thrown away when emptied, and which further. avoids the expense of washing and sterilizing equipment.

I claim:

1. An open ended container iormedfrom a blank of paper or the like having pleats forming a multi-ply bottom from the central portion of the blank and multi-ply side-walls formed from and the plies of the bottom and side walls beinl 4 portions extending radially of the central poition, the free edges of the blank terminatin substantially in a common plane at the open end of the container, and the plies of the bottom and side walls being sealed together.

2. An open ended container rectangular in cross-section formed from a blank of paper or the like having pleats forming a multi-ply bottom from the central portion of the blank and multi-ply side walls formed from portions extending radially of the centra1 portion, the free edges of the blankterminating substantially in a common plane at the open end of the container,

sealed together.

3. An open ended container rectangular in cross-section formed from a rectangular blank of paper or the like having pleats forming a multi-ply bottom from the central portion of the blank and multi-ply side walls formed from portions extending radially of the central portion, the free edges of the blank terminating substantially in a common plane at the open end of the container, and the plies of the bottom and side walls being sealed together.

4. A-container blank comprising a rectangular sheet of paper or the like having two sets of four equally spaced scorings extending at right angles to each other through the medial portions of the blank and intersecting each other at the center of the sheet to define fold lines for forming'bottom and side panels for a container, and diagonal scoring extending from the points-of intersection of the two sets of scorings and defining fold lines for folding the material Joining adjacent side panels reversely.
