CONTAINER Filed Dec. 23, 1932 INVENTOR M /e44 ORNEY8 Patented Nov. 24, 1936 UNITED STATES PATENT OFFICE CONTAINER Sardik Incorporated, poration of Delaware Application December 2 2 Claims.

This invention relates to containers and more particularly to containers adapted to form sealed sales packages especially for loose material.

Containers for packaging loose material such,

5 for example, as pipe tobacco are usually too cumbersome to be carried in a pocket, while those that are suitable for this purpose are so made that the material rapidly dries out especially after the package has been opened.

An object of this invention is to provide a container adapted to form a sealed sales package for loose material which can be used to carry the material in the pocket and which is constructed and arranged to keep the material from drying out 15 even after the seal is broken.

This and other objects which will be apparent to those skilled in this particular art are accomplished by the invention illustrated in the accompanying drawing in which,

Fig. 1 is a plan view of a strip of material adapted to be used to make a container according to one embodiment of this invention;

Fig. 2 is a perspective view of the container during the process of making;

Fig, 3 is an elevation of the finished container with the flap extended; and

Fig. 4 is a perspective view of the sealed package.

In the illustrated embodiment of this invention, 30 a container is formed from an elongated strip of whatever material it is desired to use in making the container, but which in the case of a container for tobacco comprises material which is substantially impervious to air and atmospheric moisture.

35 The material must be flexible, sufficiently strong to'withstand ordinary handling and is preferably transparent so that the contents are visible to the purchaser. Viscose or sheets of regenerated cellulose are especially satisfactory in making con- 40 talners of the type herein contemplated.

The strip 5 has a section 6 of greater width than the remainder of the body portion. A rip cord 1 is first secured in the end of the strip by folding and closing the end thereof over the cord in the 45 manner illustrated, the corners B at each edge being preferably cut away. The rip cord is so arranged that when employed to open the package it will be entirely removed therefrom and not left loosely hanging from one end. This is accomplished by providing either or both ends of the rip cord with an enlargement or anchor 1', which prevents the cord being drawn longitudinally through the enclosing fold without breaking the 55 seam, but which when the cord is used as herein- Jersey City, N. J., a cor- 3. 1932, Serial No.. 648,536

after described to break the seam permits the cord being entirely removed and thrown away.

After the rip cord is secured in place the wide section 6 of the strip is folded upon itself to form a flap 8. The edges of the wide portion are also folded so as to close the seams between the edges of the flap and the body portion of the strip and thus form a material-holding pocket. Preferably, the edges are folded in such a way as to effectively close not only the seams along the sides of the pocket but to insure the closing of the joint formed by the seam at the bottom of the pocket. For example, the edges 9 of the body portion of the material are folded inwardly and located between the'flap 8 and the body portion, while the edges Ill of the flap are folded so as to extend around or embrace the edges of the body portion adjacent the folds 9 and engage the rear face of the body portion. A suitable sealing composition is applied to the foldedledges to secure the edges in place and seal the seams against the passage of air and moisture, rendering the joints air and moisture tight. The inwardly folded edge 9 provides a surface on which to apply the sealing composition to seal the same'against the inner face of the flap 8 and the folded edge i provides a similar surface and is sealed against the rear face of the body portion of the container.

It will be apparent that the rip cord I is positioned adjacent the open mouth of the materialreceiving pocketl One or both ends of the' cord are accessible for the purpose of opening the sealed package, and the anchors prevent the'cord being drawn longitudinally without breaking the sea After the material, such as tobacco, has been placed in the pocket, the mouth is sealed closed by a suitable sealing composition applied to the surface ll of the foldededge containing the rip cord for sealing the folded edges and the material of the strip together. The extended flap is folded around the pocket in the manner illustrated to enclose and protect the same. The container is air tight and the material is thoroughly protected thereby. When it is desired to open the package the flap is unfolded and an exposed end of the rip cord or string pulled to cut through the edge of the associated fold and open the pocket mouth, the anchor I holding the opposite end of the cord in place until the fold has been entirely 50 ripped through whereupon the cord can be thrown away. It will be apparent that the folded edge II will be left adhering to the strip at the line of the mouth so as to reinforce the strip at that point. After the mouth of the pocket has been 55 opened to give access to the material, the pocket can be closed and satisfactorily sealed to protect the material and prevent drying out thereof merely by folding the container and wrapping the flap around it in the manner illustrated. For this purpose the size of the pocket relative to the amount of material carried is preferably such as to permit the container being folded along a line l2 below the mouth of the pocket but above the material. When so folded and the flap wrapped around it, the mouth of the pocket is closed and the material will be kept from drying out.

We claim:--

1. A container having in combination a flexible strip of material substantially impervious to air and moisture, a pocket formed in said strip, the edge of said strip at the mouth of said pocket being folded inwardly and the surface of said fold adjacent said strip being sealed to said strip so as to close the mouth of said pocket, and means located in said fold for severing said folded edge to open said mouth while leaving the material of said folded edge adhering to the strip of material to provide a reinforcement at said mouth.

2. A container having in combination a flexible strip of material substantially impervious to air and moisture, a pocket formed in said strip, the edge of said strip at the mouth of said pocket being folded inwardly and the surface of said fold adjacent said strip being sealed to said strip so as to close the mouth of said pocket, and a rip cord located in said fold for severing said folded edge to open said mouth while leaving the material of said folded edge adhering to the strip of material to provide a reinforcement at said mouth.
