2 Claims.
This invention relates to container construction and more particularly to a container construction of paper, cardboard, or like material.
One of the objects of this invention is to provide a simple, eflicient, economical and practical container construction made of a material like heavy paper, cardboard, or other fibrous or cellulose or like material. Another object is to provide a container construction that will be simple and inexpensive to manufacture and well adapted to meet certain kinds of uses, such as, for example, where the container body and its bottom should be tight but need not meet certain peculiar requirements of liquid-tightness, and the like, of other fields of container uses. Another object is to provide a container construction particularly adapted for handling bulk materials which may or may not be wet, also materials that are plastic in consistency, like ice cream, and the like, and that will be strong and durable and sufficiently tight or liquid-proof to meet the requirements of such materials, while at the same time maintaining simplicity and inexpensiveness of manufacture. Another object is to provide a container construction of the above-mentioned character that will be light, strongand durable. Other objects will be in part obvious orin part pointed out hereinafter.
The invention accordingly consists in the features of construction, combinations of elements, arrangements of parts, and in the several steps and relation and order of each of the same to one or more of the others, all as will be illustratively described herein, and the scope of the application of which will be indicated in the following claims.
In the accompanying drawing in which are shown several of the various possible embodiments of the mechanical features of my invention,
Figure 1 is a development or plan view ofa blank out of which the container body may be formed;
Figure 2 is a perspective view showing the blank in certain stages of the folding operations performed on it;
Figure 3 is a side elevation of the container body; and V Figure 4 is a view as seen from the bottom in Figure 3.
Similar reference characters refer to similar parts throughout the several views in the drawmg.
Referring first to Figure 1, I have there shown bounded by preferably parallel edges and 2| and end edges 22 and 23, the latter being shown as broken away in order to indicate that the top or closure portion of the container body may be made up in any appropriate or suitable form. The blank is made of a suitable material, preferably a paper product such as heavy paper, cardboard, or other analogous or fibrous or cellulose material, hereinafter termed simply paper.
Intermediate of the parallel side edges 20 and 2| there extend across the blank two parallel score lines 24--2628 and 25-2'l-29, and centrally thereof is outlined a bottom A by the score lines 26 and 2! and the transverse fold or score lines 30, 3 I, the bottom A being quadrangular and illustratively square. Score lines 28, 3| and 29 thus encompass an end wall B and score lines 24, 30 and 25 encompass an end wall C, these being also quadrangular and where the ultimate container is not to' be tapered for nesting or like purposes, end walls B and C are preferably rectangular or square. v
To each side of the end wall B are side wall portions E and F encompassed within the score line 28, edge 20, and an interconnecting score line 32, and by score line 29, edge 2|, and an interconnecting out line 33, respectively; where the container body is not to be tapered, score lines 32 and 33 are straight-line extensions of the score line 3|.
In similar manner, the end wall C has side wall extensions G and H excepting that the blank is out along the line 34, which, with score line 35 is in line with the score line 30. Also, a diagonal line of cutting 36 extends from the upper righthand corner of the side wall portion G to the upper right-hand corner of the bottom A and in a similar or symmetrical manner there is a line of cutting 31 extending from the lower left-hand corner of the side wall portion F to the upper right-hand corner of the side wall portion I-I.
Preferably, but not by way of limitation, the quadrangle formed by the triangular flaps A and El is equal to the quadrangle of thebottom A, as is also the quadrangle formed by the triangular flaps A and H In forming the container body, folding operations, as indicated in Figure 2, are carried on in appropriate sequence after applying a suitable adhesive, as indicated in Figure 1, to the flaps A E side wall portion E, and flaps A and H and side wall portion H. The parts Gr, C and H as a unit may first be folded about the fold line 39 (see Figure 2), and the side wall portion G bent or folded to an appropriate extent about fold line 24 to bring the lower edge of the Wall portion G, as viewed in Figure 2, into substantial coincidence with the fold line 26 of the bottom A,
whereupon the flap A is folded upwardly about" I and comprising a four-sided bottom, two opposed the fold line 25 against the lower portion of the side wall portion G, thus bringing into action the adhesive carried by flap A which becomes secured to this side wall portion.
These folding operations may take place with respect to a suitable block of a volume and shape corresponding to those of the ultimate interior of the container body and the next folding steps may comprise a folding upwardly about the fold line'3! of the parts E, B and F as a unit, throughout about 90 where there is to be no taper in the container body; the side wall portion E is thereupon folded about score line 28 to bring its adhesive-bea'ring face against the outer face of part G and the outer face of flap A which had already been adhesively secured to'part G, flap E projecting downwardly. In a similar manner side wall portion'F is folded about score line 29 to bring its left-hand edge, as seen in Figure 1, into coincidence with the score line 2'! of the bottom A, then flap A is folded upwardly about score line 2'! to bring its adhesive-bearing face against the outer face of portion F. Side wall portion H is then folded about score line 25 to bring its adhesive-bearing face against the outer faces of the now overlapped parts A and F, leaving flap H projecting downwardly, like flap E Thereupon, flaps E and H are folded about their respective fold lines 32 and 35 up against the under face of the bottom A to which they become secured through the adhesive which they carry and against which they are laid and secured to appear as shown in Figure 4 in which it will be seen that, assuming, as in the preferred case, that the flaps are appropriately dimensioned with respect to the bottom A, the two triangular flaps E and H completely cover over the under face of the bottom A.
Thus, the bottom A- becomes reinforced in several ways. For example, it may thus be given two thicknesses or two plies of the material, thus also to resist wear and tear better, but also, because the fiaps E and H are integral with the side wall portions E and H, respectively, the latter parts take part in carrying the load or strain imposed upon the bottom A itself. Furthermore, this construction also reinforces the junction of the bottom A-along its score lines or edges 25 andlll to the composite side walls GE- and HF, between the portions of which the upwardly extending flaps A and A (Figures 2 and 3) extend and are secured, and thus, if desired, flaps A and A may be made smaller and also the parts of which these composite side walls are made may individually be made smaller or given shapes to eifect additional saving in paper or raw materials. But flaps A A become securely anchored between the two last of the respective side walls G-E, and H-F and thus aid the flap E and F respectively, in transmitting the load on the bottom to the respective side walls.
sides'of which are extended to form opposed end walls, the latter each having lateral extensions, juxtaposed lateral extensions being overlapped and adhesively secured together thereby to form opposed side walls, said bottom having flap extensions one at each of its two remaining sides and each flap extension being joined to said bottom throughout the length of the said side of the bottom, whereby said two remaining bottom sides form axes about which said flap extensions may be respectively folded, said flap extensions being folded about their respective said axes upwardly and respectively received in between and adhesively secured to the overlapped lateral extensions of said two side walls, the latter having flap extensions which are respectively complements to said two flap extensions of said bottom and which complement each other when folded respectively about the aforesaid axes and against said bottom, together matching the area of the latter, said side wall flap extensions being so folded against said bottom and adhesively secured to said bottom to cover over the latter and reinforce it throughout its area.
2. A paper container made of a single sheet and comprising a four-sided bottom, two opposed sides of which are extended to form opposed end walls, the latter each having lateral extensions, juxtaposed lateral extensions being overlapped and adhesively secured together thereby to form opposed side walls, said bottom having flap extensions one at each of its two remaining sides and each flap extension being joined to said bottom throughout the length of the said side of the bottom, whereby said two remaining bottom sides form axes about which said flap extensions may be respectively folded, said flap extensions being folded about their respectiv said axes upwardl and respectively received in between and adhesively secured to the overlapped lateral extensions of said two side walls, the outermost of each of said overlapped lateral extensions that form said two side walls having downwardly directed flap extensions which, where they respectively join the outermostof said overlapped lateral extensions, are of dimensions at least equal respectively to the lengths of said two remaining sides of said bottom and are folded about said respective axes against and adhesively secured to the under face of the bottom, whereby the two angles formed by the bottom and said two side walls are, throughout their respective 'apexes which are formed by said axes, at least double-walled, said two side wall flap extensions being together of an area completely covering over said bottom when adhesively'secured thereto, thereby to make said bottom at least double-walled.
