Application December 30, 1932, Serial No. 649,662

Renewed November 21, 1933 2 Claims. (Cl. 229-51) This invention relates to paper 'containers such as are described inthe application of Elmer Zeb-` ley Taylor Serial No. 570,427.filed 22nd. October 1931, and in that of- Edmund Paul Herrmann 5 Serial No. 632,598 led 10th. September 1932, and comprising in `each, case a conical double-walled vbody in one end of which a bottom is secured. After filling a closure is to'be applied to the other end, and special means are described in both of the said prior applications for subsequently opening the container, consisting in the formation of two weakening linesy around that part of the blank which forms the end of the body at which the container is to be opened, so that the strip l5 between such weakening lines -can be torn out,

thus enabling thatv end of the body and the closure secured therein to be removed, or if the 4'weakening lines are interrupted at a suitable point to be turned as on a hinge, in either case y exposing the contents' for use as required.

The present invention relates particularly to containers of this class in which the weakening lines are interrupted, so that the end with its closure can be turned as on a hinge, and consequently can be readily replaced if required, and it consists in so arranging the weakening lines that a tab will be left on the hinged closure which Will when the latter is closed down again fit over the outside of lthe body and so prevent the closure from entering the contents or going too far into the container.

The accompanying drawing shows in Fig. 1

part of the container made according to the invention, Fig. 2 showing same on a larger scale and at right angles to Fig. l with the strip torn out to open it and the closure portion opened on the hinge, and in broken lines part of such closure closed down again. Figs. 3 and 4 are plan views of the blank for the conical body of the con- '40 tainer, showing two suitable arrangements'of the weakening lines with the special features of the present invention applied thereto.

Referring to Figs. 3 and 4 it will be seenthat the blank 1 for the conical body 2 of the container is formed with two weakening lines 3, 4,

extending right across such blank except at the portion 5 which when the container is made and opened constitutes the hinge. Such weakening lines 3, 4, may as described in the application of Elmer Zebley Taylor Serial No. 570,427 above referred to be arranged, as shown in Fig. 4 of the accompanying drawing so that the line 3 extends substantially parallel to the edge of the blank throughout its length, while the line 4 is parallel thereto along that part which forms the inner wall of the body when rolled up and then widens out spirally along the part that forms the outer wall, a tab 11 being lpreferably left on the blank between the ends of the weakening lines to enable the strip 7 between the latter to be easily 60 torn out when the container is to be opened. Or

4such weakeninglines 3, 4, maybe arranged as shown in Fig. 3 and described in the application of Edmund Paul Herrmann also aboveJ referred to, in which they are parallel with each other throughout their length but wider apart in that part ofthe blank 1 which forms the outer wall of the body of the container when rolled up, a cut 6 being formed at a suitable point which can be grasped to tear out the whole of the strip 7 be- 70 tween the weakening lines 3, 4, when it is desired to open the container.

In either case the weakening lines 3, 4, are stopped at a point 5 which preferably coincides with the lapped joint when thebody is rolled 75 up, so that this part will not be removed when the strip is torn out and will be left to form a hinge on which the upper end of the container with the closure 8 secured therein can be turned when desired to gain access to the contents. The essential feature of the presentiinventionconsistsin the formation of the weakening line 3 with a bend 9, the eifect of which is that when the strip 7 is torn out a tab 10 will be left depending from the closure part, which tab when 85 such closure partis turned down again to the position shown yin broken lines in Fig. 2`wi1l prevent the closurepart from being pushed down too far into the container, as such tab 10 ts over the outside of the uncovered inner wall.

'I'he bend 9 is preferably formed in weakening line 3 at a point that will bring it when the blank is rolled up immediately opposite the point 5 where the weakening lires. 3, 4, are interrupted to form the hinge. y

The end closure 8 is shc wn as being secured in the end of the body 2 by turning over the upper edge of the latter into contact with the ange of the end closure, but it will be understood that same may be secured in position in any other suitable manner.

Also it will be understood that although the weakening lines 3, 4, are shown in the drawing as being arranged at the smaller end of fthe con- 105 taincr, so that the latter is to be opened at that end, such weakening lines 3, 4, may be formed at the opposite end of the blank if it is desired that the container shall be opened at the larger end.`

What I claim and desire .to secure by patent isz- 1. In a paper container comprising a doublewalled body and suitable end closures, and formed from a body blank having weakening lines around same to enable a strip to be torn out when it is desired to open the container, such weakening lines being interrupted at a suitable point to leave a hinge on which the closure end of the container can be turned, one of such Weakening lines at a point spaced fromthe hinge forming a bend which projects toward the other weakening line and which bend forms the out- Leonesa LOUIS FREDERICK FAILOWS.
