Application May 6, 1933, Serial No. 669,666

25 Claims.

(Granted under the act oi March 3, 1883, as

amended April 30, 1928; 370 0. G. 757) The invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment to us of any royalty thereon.

This invention relates to a container and to a method of forming the blank from which the container is to be made.

In containers formed by wrapping a thin and flexible material about an article and then sealing the joints, it has been proposed to employ a separate strip or band, which may or may not be made integral with the blank by adhesive union, and terminates in or cooperates with a projecting portion that is to be grasped and pulled in eflecting an opening of the container.

The purpose of this invention is to provide the blank with a. band which, instead of being made integral with the blank by adhesive union, is formed directly therein to provide an area of increased thickness of the material.

. To these and other ends, the invention consists in the construction, arrangement and combination of elements described hereinafter and pointed out in the claims forming a part of this specification.

Several practical embodiments of the invention are illustrated in the accompanying drawing, wherein:

Fig. 1 is a perspective view of a container provided with the improved means of opening the same.

Fig. 2 is a plan view of the blank from which the container is formed.

Fig. 3 is an exaggerated sectional view on the line 3-3 of Fig. 3.

Fig. 4 is a modification showing a variation of the cross-section of Fig. 3.

Figs. 5, 6, 7, and 8 are modifications.

Referring to Fig. 2, there is shown a blank 5 which is a thin sheet of 'flexible material, imperforate and substantially impermeable, adapted to be wrapped about a package or articlefi and have its overlapping ends 'l-1 secured by an adhesive union to provide sealed joints.

A tab 8 projecting from the blank is arranged, after the container is formed by wrapping the blank about the article, to extend beyond the sealed'joint and project from the container. This tab indicates the portion to be grasped in openingthe container.

As clearly shown in Figs. 3 and {the material of the blank is formed with an increased thickness, this area constituting a band 9 which includes and is in continuation of the tab 8.

The band of extra thickness may be included in the primary preparation of the material forming the blank, or it may be provided secondarily by the application to a sheet of material, of a liquid or plastic of the same or similar composition as the material and therefore capable of solidifying so as to provide a homogeneous .or coalesced structure. The second method facilitates the application of bands having a color different from that of the sheet or blank.

The lines of junction i9i0 established between the band and the adjoining portions of the sheet or blank preferably meet the angles H-il between the tab 8 and the edge of the blank This provision coupled with the reinforcement supplied by the increased thickness of the band will insure the starting of tears in the material across the sealed joint and a continuation of the tears along the general intended lines of separation.

If the lines of junction i2, as shown in Fig. 5 do not meet the angles I3 but are inside of the angles, the tears may converge until they meet the lines of junction I2.

,The extra thickness provided by the band will not interfere with the formation of a sealed joint between overlapping ends. I

In the modification shown in Fig. 6 the blank is formed with two spaced bands l4|4 and the intermediate portion l5 constitutes a band of less thickness and is in continuation of the tab I6.

In Fig. 7 two spaced bands lll'| are in continuation of two tabs Iiil8. In this case either one of the banded portions may be selectively removed. The portion between the banded portions is preferably adhesively united to the article with in the container so that when one part of the container is removed the other part will remain in place and still be provided with a tear strip.

In Fig. 8 the band I9 is supplied by an adhesive union between the material of the blank and the article to be wrapped. The tab 20 when pulled will cause separation of the containeron the line of junction 21 and the left hand portion of the continuation of the intermediate portion between the banded portions.

2. A container for a package formed of a substantially impermeable material having sealed joints and having an overlapping end, a portion of said end projecting from the container beyond the sealed joint of said end and forming an angle beyond the sealed end so as to provide a point at the apex of the angle for the purpose of starting a tear in the overlapping end across the sealed joint, said container having spaced homogeneous banded portions of increased thickness in general continuance of the sides of the projecting end.

3. In combination with an article, a container for the article formed of a substantially impermeable material having sealed joints and havin'g an overlapping end, tabs on the overlapping end projecting from the container beyond the sealed joint of said end and forming angles beyond the sealed end so as to provide points at the apices of the angles for the purpose of starting tears in the overlapping end across the sealed joint, said'container having spaced homogeneous banded p0rtions of increased thickness in general continuation of the tabs,and the intermediate portion between said banded portions adhesively united to the article within the container.

4. A container for an article formed of a substantially impermeable material having sealed joints and having an overlapping end, tabs on the overlapping end projecting from the container beyond the sealed joint of said end and forming angles beyond the sealed end so as to provide points at the apices of the angles for the purpose of starting tears in the overlapping end across the sealed joint; said container having spaced homogeneous banded portions of increased thickness in general continuation of the tabs.

5. In combination with an article, a container for the article formed of a substantially impermeable material having sealed joints and having an overlapping end, a. portion of said end projecting from the container beyond the sealed joint of said end and forming an angle beyond the sealed end so as to provide a point at the apex of the angle for the purpose of starting a tear in the overlapping end across the sealed joint, a banded portion of the container adhesively united to the article in the container and the line of junction between such adhesively united portion and the adjoining portion of the container being generally in continuation of the apex of the angle formed by the projecting portion.
