2 Claims. (01. 229-7) The object of this invention is to provide a paper container suitable for use in cafeterias and elsewhere for containing milk, orange juice, or other drink, and from which the liquid is to be withdrawn through a straw.

The improved container is illustrated in Fig. 1 of the accompanying drawing, while Fig. 2 shows the blank from which the body po'rtionor side wall thereof may be made. Figs. 3, 4 and 5 show modifications in the method of carrying out the invention. Fig. 6 is a detail sectional view on a larger scale of one comer of the container.

Referring to Fig. 2 it will be seen that the blank I is mainly of the curved shape necessary 5 for the formation of a conical container, and is of such a size that when rolled up it will form a double-walled body. The part 2 thereof to the left of the broken line A forms the inner ply of the side wall, while the part 3 to.the right of such line forms the outer ply. In a suitable position in the irmer portion 2 of such blank a hole 4 is formed larged enough for the easy insertion of a straw, and at the outside edge of the part 3 perforations or weakening lines 5 are formed in such a position that when the blank is. rolled up to form a conical body of the container the part enclosed by such perforations orweakening lines will lie over and close the hole 4,

as shown in Fig. 1. A tab or extension 6 is 30. preferably formed at the edge of the blank I, for the purpose hereinafter described.

In the process of manufacture of the improved container the blank I is first rolled up into conical form and secured by a. suitable adhesive, 35 very little if any of the latter being applied to the part of the blank between the perforations or weakening lines 5.

For the closure at the smaller end of the container it is preferred to employ a flanged disc I, 10 and to secure same in the body by rolling the edge of the latter over into contact with the flange of such disc and continuing the rolling operation so that both flange and body" are rolled together. The closure'l mayhowever be secured in position in any other desired manner.

It is intended that the container thus formed.

with a closure at its smaller end shall then be treated with paraflin wax or other suitable substance for waterproofing and sterilizing it, this treatment being relied on to give sufficient adhesion to the part between the weakening lines '5 to maintain a suitable covering over the hole 4 in the inner ply of the side wall and prevent leakage of the contents of the container therethrough. e

The container is to be fllled with its larger end uppermost, and, after filling, the closure at such larger end is to be inserted. Suchv closure is also preferably in the form of a flanged disc 8, and is to be inserted into the body until it 5 comes in contact with a shoulder 9 formed in the latter, and the edge of the body is then preferably rolled down onto the flange and the rolling continued including such flange, in the same way as at the other end.

The container thus filled and completed is delivered with its smaller end at the top'as shown in Fig. 1, and when it is desired to open same to partake of the contents the tab 6 is grasped and the part between the weakening lines 5 can then 15 be easily turned back to expose the hole 4, through which a straw can be inserted for drawing off the contents.

- If desired the rows of perforations or weakening lines 5 may be joined at their inner ends, as 20 shown in broken lines in Fig. 2, so that the part thus surrounded can' then be entirely removed.

In some cases it may be preferred to insert the straw through one of the end closures instead of through the side wall of the container, and to en- 5 able this to be effected arrangements such as are shown in Figs. 3, 4 and 5 may be adopted.

In Fig. 3 the end closure is formed of two layers of material, in the inner of which (when in position in the container) a hole 4 is formed, while in the outer layer perforations orweakening lines 5 are formed, the arrangement being therefore substantially the same as that shown in Figs. 1 and 2. The-two layers are secured together in any suitable manner and as in the form shown-in Figs. 1 and 2 the treatment with paraifin wax or thelike may be relied on to give suificient adhesion .to the part which is to be raised to uncover the hole. f

A similar result may be obtained by the means shown in Fig. 4, in which instead of forming theend closure of two layers of material it is formed of one only, a hole 4 being made therein as in the other arrangements. This hole is to be covered by a separate piece of material, .as III, which is secured to the closure by means of adhesive applied to the part lshown shaded in Fig. l the remaining portion (which constitutes a tab by means of which the piece Hi can be lifted and removed to uncover the hole) being left free from 5 adhesive the treatment with paraffin wax or the like being again depended upon to hold such unpasted part down sufliciently well for the purpose until it is desired to gain access to the contents I of the container.

Fig. 5 illustrates a further modification, in which the end closure is again formed of a single layer of material. 'In this case the hole 4 is to be punched only about half way through the thickness of the material, from the underside, while the weakening lines or perforations 5 are punched also half way through the material but from the upper side. With this arrangement the container can be easily opened by raising the part enclosed by the half out through weakening line'5 at the point II, when such enclosed part will in rising take with it the part closing the hole 4, and so afford access to the contents.

What I claim as my invention, and desire to secure by patent, is:-

1. A paper container comprising a tubular body having its wall composed of an inner layer and an outer layer, said layers being formed from a longitudinally curved blank and being continuous from end to end of the blank, said inner layer having an opening near the center of said blank constituting the point of junction between the inner and outer layers, and said outer layer in the portion thereof which covers said opening having weakened lines defining sides of a. tab to uncover said opening, said tab extending to the exposed end of said outer layer.

2. A paper container comprising a tubular body having its wall composed of an inner layer and an outer layer, said layers being formed from a blank of the curved shape necessary for the formation of a conical container, said inner layer having an opening near the center of said blank constituting the point of junction between the inner and outer layers, and said outer layer in the portion thereof which covers said opening having weakened lines defining sides of a tab to uncover said opening, said tab extending to the exposed end of said outer layer.
