Application October 9, 1934, Serial No. 747,586
3 Claims. (craze- 51 This invention relates to paper containers such as are describedfin the specifications of Elmer Zebley Taylors United States Patent No. 1,961,-
535 and Edmund Paul Herrmanns United States 5 Patent No. 1,963,994, in both of which containers such as are applicable for use in the delivery of milk and the like are described. These containers comprise a conical double-walled body and suitable end closures, and it was proposed to open them by tearing out -a strip of material between two weakening lines suitably disposed for the purpose.
The object of the present invention is to simplify the method of opening, and it consists in forming the container with a single wea'kening line around the outer wall thereof and a cut around the inner well, this weakening line and out being so disposed that by pressing the side of the body inwardly immediately below the weakening line the latter will be broken, when the upper end of the container can be grasped and the breaking completed by a hinging movement, enabling the upper end of the body with the closure secured therein to be removed, exposing part of the outer surface of the inner wall, the upper edge of which will be smooth and clean owing to the presence of the cut, and over which the contents can be poured if of liquid form. If
desired the separated top and closure can be replaced to form a cover if all the contents have not been removed.
The invention is illustrated in the accompanying drawing, in which Fig. 1 is a plan view of the blank for the body, Fig. 2 a side view of the upper endof a container, Fig. 3 a sectional view thereof showing the method of opening, and Fig. 4 a similar view of the opened container with the removedtop readyto be applied as a cover. Fig. 5 is a detail view of the preferred form of the weakening line in the outer wall of the body.
In Fig. 1 of the drawing it will be seen that the blank Ifor the body is formed with a weakening line 2 in that part A which is to form the outer wall when such body is rolled up, such weakening line being preferably as shown in Fig. 5 formed by a double series of perforations 5 of which those in one row are opposite the spaces between those in the other row. The weakening line 2 is preferably arranged parallel or approximately so with the edge of the blank I, and from its inner end a cut 3 extends towards such edge, and then continues parallel or approximately so therewith around the part B of the blank which is to form the inner wall of the body.
To facilitate the rolling-up operation, particularly when this is effected by automatic machinery, it is preferred to interrupt the cut 3 at suitable intervals, as I, which will have the elfect of holding the blank together, so that there will not be a narrow loose end, consisting of the part 5 marked 6, depending from the blank, and which might interfere with the rolling operation.
The blank I is intended to be rolled up to form a conical double-walled body the smaller end of which is shown in Fig. 2 in elevation, and in Fig. 3 10 in section. Into this smaller end a closure such as I is insertedin the course of manufacture, the other or larger end being left open until the container has been filled, after which a suitable closure is also to be inserted therein. It is intended that the container shall then be reversed so that the smaller end in which the opening means described are formed becomes the top.
When it is subsequently desired to open the container this can be'readily effected by press- 20 ing on the side of the container immediately be neath the weakening line 2, as shown in Fig. 3, whereby the material of the outer wall willbe broken along the weakening line. When this has been done the upper end of the container is to 2'5 be grasped at the point 8 (Fig. 3) and the-breaking of the material along the weakening line completed by a hinging movement. This movement will also break the interruptions 4 if same are formed in the cut 3, so that the entire top with 30 the closure I can be removed.
In the rolling operation themechanism employed for applying adhesive to the blank is so arranged that such adhesive shall not be applied to the part thereof which when the body is rolled 35 up is between the weakening line 2 and the cut 3, the subsequent treatment with paraffin wax or other material giving sufficient adhesion at this point until the container is opened, but readily yielding when this is done. v 40 If the removed top is to be subsequently used as a cover it is preferred that the cut 3 should beformed at such a position in the blank I that when the container. is made upv it willbe slightly above the under surface of the closure I, as shown 45 in Fig. 4, so'that a slight groove 9 will be left when the top has been removed, into which the remaining upper edge of the container (left by such cut 3) will enter if the top is replaced toserve as a cover, so making a good joint, which will be assisted by the small fillet of wax, shown at Iii in Figs. 3 and 4, which is usually obtained in carrying out the waxing operation. Before replacing the top to use it as a cover the part of the upper edge of the body which was 55 mately parallel with the edge of the blank from which the container body is made but extending around the outer wall only, and connecting with a cut around the inner wall also approximately parallel with the edge of the blank but nearer such edge than the weakening line in the outer wall, as set forth.
3. A double-walled conical paper container provided with means for opening same comprising a single weakening line extending around the outer wall, and connecting at its inner end with a cut extending around the inner wall with the exception of interruptions at suitable points, as and for the purpose set forth.
