2 Claims. (01. 22917) This invention relates to a pour containenland more particularly, to a non-drip pour container and to a type of container which may be shipped or transported in stacked relation with similar sealed containers carrying fluid contents such as liquids, cereal, or other particulate materials that flow. The invention is particularly useful in connection with thepackaging of milk; cream and other liquid.

An object of the invention is to provide a container so arranged as to provide a tight seaifor the transportation of liquids or particulate flowing materials, while being readily opened to provide a pouring spout or channel, while eliminating dripping.

Yet another object is to provide a container adapted to be sealed in a square or other form the top of the container being arranged for opening to expose folded portions providing a pour spout, etc.

Other objects and advantages will appear as the specification proceeds:

The invention is illustrated in preferred embodiments by the attached drawings in which- Figure l is a perspective view of a container embodying my invention;

Figure 2, a view similar to Fig. l, but showing the top flap raised;

Figure 3, a perspective View of the container turned to pouring position;

Figure 4, a broken detailed sectional view, the section being taken as indicated by line 4-4 of Fig. 1;

Figure 5, a broken detailed sectional view, the section being taken as indicated at line of Fig. 1;

Fig. 6, a top plan view of the die-cut sheet from which the container is formed;

Figure '7, a vertical section View, the section being taken as indicated at line 'l| of Fig. 1;

Figure 8, a broken sectional view similar to Fig. 7, but showing a modified form of structure.

In the illustration given a fiat strip of paper is die-cut, as shown in Fig. 6 and preferably indented to form fold lines. The other lines are indicated by solid lines in Fig. 6, while the folded lines are indicated by the dotted lines Ill. The side walls of the container are formed by the sides H, [2, I3 and I4 as indicated in Fig. 6 and the flaps I5 and [6 are provided for reinforcing the sealing joint. The lower flaps l1, l8, l9 and are folded to form the bottom of the container, as in usual practice,

The top flap 2| serves an important function in providing a seal for the top of the container.

2 This flap is provided atone end with a; cut out or aperture 22 to permit the flow of liquid there through. The flap 23 forms the top or outside seal for the container. The flap 24 is adapted to be folded inwardly at an intermediate point and above the adjacent flap 25. 'The adj'aceiit' flap 25 is folded upon itself at the fold'lin'e 26. As will be later described, the flaps 25 and 24 co operate'in forming the spout for the pouring of the milk, etc. and the bottom ofthe channel of the spout is the folded line 21.

I prefer to equip the flap I6 with an upper 'ex tension 28 inorder' that this pull flap 28 may be utilized in the opening of the container top.

The container may be folded and united by glue, Wax or by any other sealing means. The container itself may be formed of paper rendered waterproof by plastic materials, waxes or any other well known means or it may be formed of other flexible material such as plastic sheets, etc. The flat sheet, as shown in Fig. 6 is folded upon itself as illustrated in Figs. 1 to 5 and 7 inclusive so as to form a square container and the finished sealed container appears as shown in Fig. l. I prefer to have the flap 23 provided with an extension 29 and with a pour pull. flap 30, as shown more clearly in Figs. 1 and 6.

The finished container may be left with the flaps 2|, 23, 24, 25 and 28 extended for the fillin operation and. thereafter the flaps may be folded inwardly, first the flap 2| being brought into sealing position Within the container. Next the flap 25 is folded into position, the flap 25 being folded upon itself. The outer fiap 23 forms the closure for the container and the overlapped portion 29 provides a reinforced front edge. The top portion or tab 28 provides a seal which at the same time can be readily pulled to open the container. If desired, flaps 29 and 39 may be omitted or may be varied in shape as desired for sealing. The flap 29 may be slit to improve the seal.

When it is desired to open the container for pouring the milk or other liquid, the flap 39 is grasped and drawn upwardly as shown in Fig. 2. The flap 24 is then drawn forwardly to the position shown in Fig. 3 for pouring. This causes the channel portion formed by the two flaps 24 and 25 as shown in Fig. 3, to be aligned with the aperture provided in the corner of the flap 2| so that liquid or fiowable particulate materials may flow readily from the container and through the spout which may be indicated as an entirety by the numeral 32 as shown in Fig. 3.

In the modification shown in Fig. 8, the structure is identical as that heretofore described except that I have provided the lowermost flap within the container, namely, flap 2| a with attachment flanges 2 lb and the attachment flanges are preferably cemented to the side walls of the container, thus providing a rigid sealing wall 2 la fixed firmly to the interior walls of the container and providing a single outlet 33.

The invention has been described by way of example, in connectionwith a container for milk; In the case of materials such as sugar, materials and other materials consisting of small flowabl'e solids, it may be desirable to vary the size or shape of the aperture 22 in flap 2|.

While in the foregoing specification, Ihave set forth a specific structure in much detail for the purpose of illustrating one embodiment of myin-- vention, it will be understood that such details of structure may be varied widely by those skilled in the art without departing from the spirit of my invention.
