CONTAINER Filed July 3, 1935 /lllllll/llllI/IIIIIL Vllllllllllllllllllj INVENTOR BY ATTORNEYV Patented Oct. 27, 1936 UNITED` STATES CONTAINER Ralph L. Bangs, Wakefield, Mass., assignor to Forest Wadding Company, Roxbury, Mass., a corporation of` Massachusetts Application July a, 1935, serial No. 29,593

5 claims. (o1. 229-14) The present invention relates to the art of Hpackaging, particularly for the purpose of preserving food in its originalcondition. Such packing may be commonly used for packing meats', sh, dairy products or perishable vegetables during shipment, and also during the time they are exposed for sale.

In the present invention the container may sometimes be used more than once, but more often the container becomes soiled or wet after being used so that it cannot be used continually and must therefore be replaced. It is essential for this reason to make the container as cheaply as possible and yet in such a manner that it will efficiently and readily accomplish the purpose for which it is used.

The present invention is concerned more particularly with providing an inexpensive method of packing, particularly for such food stuffs as are perishable during shipment.

The present invention is an improvement on my previous application Serial No. 639,265, and inasmuch, is a more convenient and inexpensive container which in cases is preferred to the container of the prior application.

The present invention will be more fully understood in connection with the following description and the drawing showing an embodiment of the same, in Which:-

Figure 1 shows an interior liner of the container.

Figure 2 shows a section through the container in its open position,

Figure 3 the container entirely in a closed position, and,

Figure 4, a section through the inner liner of Figure 1.

The container is shown as it is used in Figure 3. In this ligure l indicates the outer box which may be constructed of corrugated paper walls with the lutings at the inside. The box may be made of one piece in the usual fashion with the top and bottom covers 2 and. 3. Within the box is held the inner container 4, which comprises a non stiff or flexible bag element 5 having a stiff bottorn cover 6 as indicated more clearly in the other gures. The bag element 5 may have waterproof face papers such as 'l and 8 shown in Figure 4 with insulating elements 9 between which may be batting or ground paper or some other suitable light exible insulating material.

As indicated in Figures 1 and 4, the inner liner is composed of the inner sheet 'l and the outer sheet 8. These sheets form a continuous lining element about the inside walls of the container.

The edges of the sheets may be lapped over or closed over by corner elements l0 as indicated in Figure l. The edge of the liner is preferably capped b-y a border Il adhered to the end face edges of both inner and outer sheets. The lower end may be sealed off if desired, but this may preferably be left open where the insulating material 9 within the sheets is such that it will not easily come out. This is true in the case of batting or wadding, and particularly in the present in vention where the lower end is sealed when the container is in use as will be presently described.

At the lower end of the liner or inside container 4, there is found a stiff corrugated sheet I2 which passes about the entire end of the container forming a border of the same. This corrugated sheet is glued or adhered to the lower end of the liner as indicated at I 3. Just opposite the end I4 of the liner is positioned a scoring line VI5 upon which the corrugated element is folded when the lower end of the liner is closed to form the bottom of the inner container.

As indicated in Figure 1, the corrugated paper is cut at the corners l1 so that they may be folded as an ordinary box. The corrugated board or paper l2 in being folded, folds over the lower end I4 of the liner thus sealing effectively the batting at the end. The lower 'end in its folded position forms a sti at bottom over the inner container, and provides as` is indicated in Figure 3 horizontal flutings I8 for circulation of the air within the container about the bottom of it, the container 4 itself not tting so tightly but what the circulation at the sides is possible. The top part of the container 4 may be closed over as indicated by the closing flaps I9 in Figure 3, and if desirable, a refrigerant may be placed above this.

The whole container, comprising the inner and outer elements may be shipped as one in a flat package with the ends lying flatly opened as indicated in Figure 2. The package may be assembled by first folding in position the lower aps of the corrugated board l2 of the inner container and then the outer cover 3 at the bottom of the outer container. The package may then be lled and covered, complete circulation being provided by'ensuring an air space between the flutings on the bottom part of the cardboard l2 which places the cardboard I2 above the bottom of the box.

If it is desired the refrigerant may be placed in the top of the box above the stiff pad to insure that the refrigerant will not come in direct contact with the material, and in this case, circulation will take place about the sides of the inner container and around the bottom between the flutings and the bottom of the outer container.

Having now described my invention, I claim:-

1. A container comprising an outer cardboard case, an inner container fitting within the same and substantially filling the space therein, said inner container having flexible Walls composed of sheets of paper in face to face relation with a layer of wadding therebetween, a corrugated sheet applied about the ends of the walls andl slit to form bottom covers for the inner container.

2. A container comprising an outer cardboard case, an inner exible container having an open top and comprising flexible walls formed of two sheets of parallelly disposed paper with a heat insulating layer therebetween, a corrugated sheet at one end of the walls forming a continuous border about the end thereof and cut at the corners whereby the sheets may be folded over to form a bottom of the inner container.

3. In a container of the type described, an inner liner comprising an element of iiexible outer material and inner heat insulating material,

said element being closed on four sides, a corrugated sheet attached to one end of the enclosed element and forming an end of a bag, said corrugated sheets being cut at the corners whereby they may be folded to form the bottom of the bag.

4. A container of the type described, an insulating liner having walls of outer paper elements and inner insulating material, a corrugated cardboard sheet attached atthe lower end of the liner on the external side thereof, said corrugated sheet being scored at a point just above the end of the liner whereby when the sheet is folded over to form the bottom of the inner container, the liner is sealed off at the end.

5. In a container of the type described, an inner liner composed of two exible paper sheets having insulating material therebetween, means sealing the insulation in the liner at one end and a corrugated sheet extending about the other open end, said corrugated sheet being scored about said end just above the end of the liner, said sheet being also cut so that it may be bent lto form a bottom over the liner.
