PAPER CONTAINER Filed Sept. 10, 1932 F/G.4. FIG. 5. M

Patented Apr. 17, 1934 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to paper containers such as are described in the application of Elmer Zebley Taylor, Serial No. 570,427 filed 22nd October, 1931, and which consist of a conical body 5 in one end of which a bottom is secured, the other end being closed after the contents have been filled into the container. The means described in such application for subsequently opening the container consisted in the formation of two weakening lines or indentations around that end of the blank at which the container was to be opened, so that the portion between such weakening lines or indentations could be readily torn out and entirely removed, exposing the contents for use as required.

The object of the present invention is to facilitate the opening of containers formed as described in such prior application, and the improved arrangement is illustrated in the accompanying drawing, in which Fig. 1 is a plan view of the blank for the'body, while Fig. 2 is a side elevation of part of a finished container with the opening arrangement applied to the smaller end thereof, Fig. 3 a similar view thereof when the first step of the opening operation has been taken,

and Fig. 4 a similar view showing the container completely opened. Fig. 5 shows the improved arrangement for opening applied to the larger end of a container.

According to the present invention the blank 1 for the body of the container is formed with two weakening lines or indentations 2, 3, but these do not as in the prior application of Elmer Zebley Taylor above referred to extend right across the blank 1, but only about half way across same, being formed in that part A thereof which will constitute the outer wall of the body when rolled up.

These weakening lines 2, 3, are both spirally arranged in relation to the blank, and converge toward each other as shown clearly in Fig. 1, and at their inner ends they may be joined together by a short weakening line 4. From this point a single weakening line 5 extends to the end of the blank, this line 5 being preferably parallel with the edge of the latter, as shown in Fig. 1.

The end of the strip 6 between the weakening lines 2, 3, preferably extends beyond the edge of the blank 1, forming a tab 7 which is to be grasped when it is desired to open the container. By pulling on such tab the strip 6 can be torn out, removing the outer wall of that part of the container only, and leaving the inner wall which can then be easily broken ofi along the weakening line 5. The part thus removed will carry with it the end closure 9, and as (as shown in dotted lines in Fig. 2) such closure extends down below the level of the weakening line 5 the removed part with such closure still in position can be re-inserted and. used as a cover if all the contents of the container have not been poured out.

If desired the weakening line 5 may be interrupted as shown at 8 in Fig. 1, this unweakened portion then being capable of serving as a hinge on which the top can be turned back, and returned if it is desired to close the container again.

Figs. 1, 2, 3 and 4 show the improved arrangement as applied to the small end of a container, but it will be readily understood that it'can also be applied to containers which are to be opened at the large end. Such an arrangement is shown in Fig. 5, and it will be seen that in this case the downwardly depending inwardly turned upper edge of the body of the container extends below the-weakening line 5, so that when the top is removed such depending edge will, if the top is to be replaced after opening, easily enter and form a good joint in the upper part of the container.

The improved arrangement presents the advantage over that described in the prior application of Elmer Zebley. Taylor hereinbefore referred to in that it is only necessary to tear out a strip equal to one circumference of the container, whereas in the previous arrangement the strip removed was of double the length, so that the operation issimplified and there is less waste 1 material to be disposed of.

The weakening lines or indentations 2, 3, may be produced in any suitable manner, but a suitable arrangement is to form each row as a double line of short indentations in-close proximity to each other, the space between the indentations in one line being opposite the centre of the indentations in the adjacent line. The weakening lines may also be produced by scoring with a rule, suflicient pressure being applied to perish the paper to a certain extent without actually perforating it.

What I claim and desire to secure by patent is:

1. A paper container comprising a doublewalled body and suitable end closures, the portion of the blank constituting the outer wall of the body thereof being formed with two weakening lines or indentations to enable the strip between them to be readily torn out, exposing the inner wall in which a single weakening line is' formed, as set forth.

2. A paper container comprising a doublewalled body and suitable end closures, the portion of the blank constituting the outer wall of the body thereof being formed with two weakening lines or indentations arranged spirally and converging towards each other to enable the strip between them to be readily torn out, exposing the inner wall in which is formed a single weakening line parallel with the edge of the blank, as set forth.

3. A paper container comprising a doublewalled body and suitable end closures, the portion of the blank constituting the outer wall of the body thereof being formed with two weakening lines or indentations to enable the strip between them to be readily torn out, emosing the inner wall in which a single weakening line is formed, such single weakening line being in terrupted at a suitable point to form a hinge, as set forth.

4. A paper container comprising a double-- LOO
