Application September 23, 1933, Serial No. 690,723

3 Claims.

This invention relates to paper containers such as are described in the specification of Elmer Zebley Taylors application for United States patent Serial No. 570,427 filed 22nd. October 1931 5' and of Edmund Paul Herrmanns application for United States patent Serial No. 632,598 filed th. September 1932, in each of which a container is described comprising a double-walled conical body in one end of which a bottom is secured. After filling a closure is applied to the other end, and the specifications of such prior applications describe means for subsequently opening the container consisting in different arrangements of weakening lines or indentations around that end of the blank at which the container is to be opened, so that the portion between such weakening lines or indentations can be readily torn out and entirely removed, exposing the contents for use as required.

The present invention is hereinafter shown and described as applied to containers constructed in accordance with the Herrmann application Serial No. 632,598 above referred to, in which the weakening lines are arranged parallel to each other and to the edge of the blank but are wider apart in the portion forming the outer ply than in that forming the inner ply, and a cut is formed through the blank at the point where the wider and narrower spaced weakening lines or' indentations meet, so that a tab is formed by pulling on which the portion between the weakening lines or indentationscan be torn out in a single turn around the container.

The object of the present invention is however to provide a container which while it can be opened by entirely removing the upper end thereof in the manner described in the prior applications above referred to, can if desired be only opened sufliciently to enable the contents to be poured out, the partially torn out strip being then capable of being replaced and secured to protect the contents from the entrance of dust, flies, or other deleterious influences.

The invention is illustrated in the accompanying drawing, in which Fig. 1 is a side elevation of part of a container constructed according thereto; Fig. 2 a view showing the container opened to enable the contents to be poured out;

Fig. 3 a similar view showing the strip partly replaced to close the container, and Fig. 4 a plan view of the blank for the body.

on reference to Fig. 4 it will be seen that the weakening lines or indentations 1, 2, formed in the body blank 3 arearranged parallel to each other and to the edge of the blank at the end A of the latter which forms the outer wall of the rolled-up container, and are then brought closer together at the points 4, 5, and subsequently continue parallel to each other and to the edge of the blank along the inner wall 13, a cut 6 being made through the blank between the points 4 and 5 in such a position that when the blank is rolled up it is as shown in Fig. 1 slightly outside the outer edge of the outer wall and forms a tab whichcan be grasped when it is desired to open the container. By pulling on this tab the entire strip 10 between the weakening lines 1, 2, can

be torn out by a single turn around the container, the inner narrow part of the strip being to facilitate this either partially or completely 7 secured to the outer wider part, while the adhesion resulting from the treatment with the paraffin wax or other material used for waterproofing or sterilizing the container will be sufiicient to hold the outer edges of the wider part of the strip in contact with the outer surface of the inner wall of the container until the latter is opened in the manner described.

As thus far described the arrangement is similar to that covered in the prior application of Edmund Paul Herrmann hereinbefore referred to, but it will be clearly seen on reference to Fig. 4 that according to the present invention the weakening lines or indentations-1, 2, do not continue right up to the edge '7 of the part of the blank constituting the outer wall of the rolledup body, and that from the points 1 2*, where such weakening lines are stopped

cuts

8, 9, are made through the blank, such cuts each extending inwardly from the point 1 or 2* across the strip 10 between the weakening lines 1, 2, and then turning outwardly and continuing to the extreme outer edge '7 of the blank.

The result of this arrangement is that when it is desired to open the container by pulling on the strip 10 between the weakening lines 1, 2,:

after grasping the tab formed by the cut 6, as in the Herrmann application hereinbefore referred to, the flaps 11, 12, formed by the

cuts

8, 9, will not be torn away, but will simply rise sufliciently to allow the strip 10 to pass them and will then return to their normal position against the inner wall of the container. The mechanism for applying the adhesive used in rolling up the body is so arranged that such adhesive shall not be applied 'to the flaps 11, 12, so that the latter will be free to rise as described.

The object of this arrangement is that if it should not be desired to entirely empty the container when first opened, the strip 10 may only be torn partly round as shown in Fig. 2, exposing an opening 14 between the lower surface of the closure 13 and the upper edge of the inner ply.of the body left by the removal of part of the narrower portion of the strip. This opening is quite suflicient to enable the contents to be poured out without the provision of a vent hole, and the extent to which the strip can be torn out may be previously determined if desired by arranging that the pasting mechanism employed shall definitely apply adhesive to cause the edges of the wider part of the strip 10 to be aflflxed to the inner layer of the body at a point such as 15 (Figs. 1 and 4) which would stop the tearing at that point unless, if it is desired to entirely remove the strip (as proposed in the Herrmann application above referred to) additional pressure is applied to carry the tearing action beyond such point 15.

In any case if the strip 10 has not been completely removed the present invention enables the container to be closed again if all the contents have not been poured out, as by slipping the free end of the strip under the flaps 11, 12 (the commencement of this operation being illustrated in Fig. 3) the whole strip can be returned to practically its original position as shown in Fig. I

and will be held there by the engagement of such flaps with its upper and lower edges, thus closing the opening.

To facilitate thepouring out of the contents of a container opened in the manner described, the sides of the torn portion of the strip 10 may if desired be pinched together to form a spout or trough along which the contents can pass.

Paper containers of the class to which the present invention is to be applied are usually made and sold with the closure 13 at the smaller end in position, and after filling with the milk or other contents a closure of suitable type is to be inserted at the larger end, and the container is preferably subsequently reversed so that the larger end becomes the base. The form of the closures and the method of securing them in position do not however form part of the present invention.

What I claim and desire to secure by patent is:-

1. A paper container comprising a doublewalled body and end closures and provided with means for opening same, consisting of two rows of weakening lines or indentations for the purpose of enabling the strip between them to be readily torn and turned back to leave an opening through the double walls thereof, and with means for sub sequently retaining the strip in its closing position comprising flaps adapted to engage its upper and lower edges and formed by cuts made in the outer edge of the outer wall and extending partially across the strip to the point where the weakening lines commence.

2. In a paper container comprising a doublewalled body and suitable end closures, the formation of the body blank therefor with two weakening lines spaced apart and so disposed that a wide strip can be torn out of the outer wall and a narrower strip out of the inner wall when it is desired to open the container, and cuts being formed at the outer edge of such blank to leave flaps which extend partly across the width of the strip so that after the latter has been torn it can be replaced and will be retained in its closing position by such flaps.

3. In a paper container comprising a doublewalled body and suitable end closures, the formation of the body blank with two weakening lines which are widely spaced in that part of the blank which constitutes the outer wall of the container and closer together in that part which constitutes the inner wall, a out being made through the blank at the point where the wider and narrower weakening lines meet, the weakening lines being stopped a short-distance from the outer edge of that part of the blank which forms the outer wall and cuts being formed leading from the points llii at which the weakening lines stop and extending inwardly partly across the strip and then turning 1 outwardly and continuing to the said edge of the
