QJGNTB John G. Bell, Broo, N. Y. Application April 4, 1942, Serial No. 437,650 it claims. (or. sea-4.5)

This invention relates to a new and useful improvement in containers made of paper or other sheet material, and in particular, to containers of this character intended principally for holding various semi-fluids, such as ice cream as it comes from the freezer, semi-solids and solids. Some of the important features of the container of this invention are a body composed of two sleeves of paper or other sheet material, one ilt-' ting snugly within the other, made of the same or different kinds and weights of material, a bottom, and, usually, a top. All of these parts are oi extremely simple shapes, easily and inexpensively produced and. assembled. Aside from the body sleeves, the edges of each of which are overlapped and fastened together by adhesive or stapling, the entire container can be assembled without the use of adhesive or metallic parts. The double-walled construction produced by two separate sleeves, one within the other, not only provides a structure of adequate rigidity, and considerable insulating merit, but one which is substantially puncture-proof in that the outer sleeve can be damaged without affecting the inner. The double-sleeve construction also permits the use of two different materials, for example, a high-grade paper for the inner sleeve, suitable for contact with food, and a less expensive outer sleeve for strength, etc. In short, this construction gives the greatest possible lattitude in the nature of the inner and outer sleeves, so that the container can be adapted for the greatest number of uses at a minimum of cost.

One form of the invention is shown in the drawings, of which;

Figure 1 is an illustration in perspective of a container complete;

Figure 2 is a similar illustration of the top of'this container;

Figure 3 is a similar view of the bottom of this container;

Figure 4 illustrates diagrammatically the blank from which the outer sleev of the container is made;

Figure 5 is a similar illustration of the blan Figures 6 and 7 illustrate, respectively, the outer and inner'sleeves after the folding of the top lower part of the inner sleeve on the line ll i I of Figure 9;

Figure 12 is an illustrated sectional view showing how the bottom is inserted into and positioned in the inner sleeve;

Figure 13 is a similar view illustrating the initlal position of the top of the container;

Figure 14 is a sectional view illustrating the manner in which the outer sleeve is slipped over the inner sleeve and the top;

Figure 15 is also a sectional view showing the outer sleeve in its final position with respect to th inner sleeve and the top; and

Figure 16 is a section of the container along the line l8i6 of Figure 15.

The blanks from which the inner and outer sleeves are made are shown in Figures 4 and 5. As will b seen the shape of each i such that when edges 4 and-5 and 6 and 1, respectively, are overlapped and secured by gluing or stapling, tapered sleeves with tops. and bottoms in parallel planes result.

As shown in Figure 5, the inner face of inner sleeve 2 is provided with parallel scorings 8 and 3 adjacent its lower edge, so spaced from the edges and from each other that the edge may be folded upon scoring 8 and then again upon scoring 9 to make a double fold iii, upon the inside of the sleeve, as shown in Figures '7, 9, 11

and 12. A third scoring 9a may also be included, if desired, positioned just above the double fold i0 into which the bottom can be snapped.

Double-fold i0 is the major support for the bottom ll of the container. This bottom may consist of the disk H, which is simply slipped into the upper end of inner sleeve 2, as shown in Figure 12 in dot and dash lines, and forced downwardly until it rests upon the double fold It). If scoring 91: is included, the diameter of the bottom I I should be slightly larger so that it will extend into the scoring by which it will be held against accidental displacement.

The outer sleeve I is provided with a pair of scorings l3 and :4 similar to those already described, but located at the top instead of at the bottom, as in the case of the inner sleeve. These scorings l3 and I4 permit of the inward folding of the upper edge of the outer sleeve to make a,

double fold 15, similar to double fold l0.

Top I6 of the container consists, preferably, of

a disk I'I having a circular scoring I8, the diameter of which corresponds to that of the top of inner container 2, and an outwardly-extending skirt I9 bent downwardly as shown in Figure 2.

This top I6 is placedupon the top of inner sleeve 2, edge down as shown in Figure 13, and then the bottom of outer sleeve I is passed over it as shown in Figure 14.

As outer sleeve 2 moves downwardly its decreasing diameter will cause it to engage skirt I 9 of top I6, forcing it towards the inner sleeve'until, when outer sleeve I comes to rest in close contact with inner sleeve 2, edge I9 01 the top will be held tightly between the two sleeves and also against the top of inner sleeve 2' by the doublyfolded upper edge I of outer sleeve I, as shown in Figure 15. Also the lower end of outer sleeve I will then have been forced over the bead pro- I9 of top H, and at the lower end by outwardly projecting bead produced by scoring 9a reinforced by bottom I I. Conversely, the engagement of bottom I I with scoring 9a is made more secure by the inward pressure of outer sleeve 2 against the bead, resulting from this scoring.

In assembling the sleeves I and 2 it is preferable to locate the overlapped ends 4 and 5 of sleeve I opposite the overlapped ends 6 and I of the sleeve 2, as illustrated in Figure 16. This p0 sitioning of these overlapping ends is not absolutedy necessary, but when heavy substances are packed'in the completed container, the resistance of the container to bursting strains is greatly increased.

The container is now complete, the frictional engagement between the inner and outer sleeves and between these sleeves and the top makes it unnecessary to ,fasten the two sleeves together. The result is a double-walled container, all of the parts of which are assembled without gluing or other attachment with the exception of the overlapped edges of the sleeve blanks already described, which must be attached together in order to form the sleeves.

Although a container of this character may not be absolutely liquid-tight, it is admirably adapted for holding all sorts of solids, semi-solids and even semi-liquids, such as ice-cream as it comes from the freezer. It may be made absolutely liquid-tight, if desired, by coating it with paraffine or other suitable material, without affecting its I construction or the general method of assembly.
