Serial No. 484,825.

My invention relates to shipping containers adapted for self-refrigeration and the shipment of perishable food products.

One obj ect of my invention is to provide an inexpensive shipping container for the shipment of perishable food products, such as meat, which may be utilized in combination with anhydrous refrigerant or natural water ice.

Another object of my invention is to provide a container of the class described, which has suiiicient strength and rigidity to be handled and stacked in shipment in the manner in which Wooden boxes are ordinarily handled and stacked, yet be light in weight, avoiding unnecessary tare.

Referring now to the drawings:

Figure 1 shows a preferred type of wirebound skeleton wooden crate.

Figure 2 represents the crate shown in Figure 1, in which has been inserted a fibre carton.

Figure 3 represents the crate of Figure 1 with the fibre container of Figure 2, into which has been inserted a waxed bag and corrugated inserts.

Figure 4 is a view of Figure 3 in cross section.

Figure 5 is a transverse section showing the drain spout.

In one embodiment of the invention there is contemplated a skeleton wire bound crate in which is inserted a solid fibre carton. The carton extends at its upper end above the top of the crate and is foldable inwardly of the carton and crate over goods which ma be disposed within the container thus forme The crate is preferably rovided with a lid, which may be a hinge lid 1, through the instrumentality of the wires 1b used in making up the wire bound crate, and the ends 1 of the wires may be hooked, twisted or in any other well known manner connected together, as is obvious, to fasten the lid in Aclosed position, as will be readily understood from the disclosure, particularly such as shown in Figs. 1 and 2, wherein the lid is shown in open position.

If it is desired to use the container in combination with an anhydrous refrigerant, or for any other purpose, for that matter, a waxed bag y3 may be inserted in the container within the aforesaid carton 2, within which the products may be placed along with a suitable quantity of anh drous refrigerant such as solidified carbon dioxide. The sides of the waxed bag are extended upwardly beyond the upper edge of the crate, as in the case of the carton, and these extended sides of the waxed bag are inherently foldable along with the inherently foldable sides of the carton forl disposition under the lid when the latter is in closed position. This waxed bag acts as a seal against escape of carbon dioxide gas, preventing a too ra id disinte- .gration of the refrigerant. If esired, corrugated or other liners 4 and 5 may be placed within the waxed bag within the container, and upper and lower corrugated pads 8 and 7, res ectively, may be disposed within the waxe bag of the container. The lower pad 7 is preferably disposed on the bottom of the waxed ba while the upper pad 8 is preferably of a size so that the ed thereof rest upon. the upper edges of t e liners 4 and 5, as shown vparticularly in Fig. 4.

Where` it is desired to use the container in combination with natural or artificial water ice, small drain spouts 9 may be provided, and these spouts may lead from -the bottom of the ,waterproof waxed bag, .draining 0E the water and thus preventing waterlogging of the fibre container.

It is understood that changes may be made in the manner of makin and construction ofthe container without departing from the spirit of the invention, as defined in the claims which follow. v

I claim:

1. A shipping container comprising a relatively rigid and strong skeleton crate that provides bottom and upright wall portions, a libre carton tted within the crate and providing bottom, upright wall or side, and foldable top portions and constructed so thatl the foldable portions of the u right wall or side portions extend above t e to of the crate and so that said portions w ich ex- 10 tend above the top of the crate are inwardly foldable into horizontal position to com lete a closed carton, a waxed bag fitted within the fibre carton and having upright wall or 5 side portions that extend above the top of the crate whereby the portions of the bag which extend above the top of the crate are inwardly foldable to horizontal position to complete a closed bag, wall liners disposed within the waxed bag along the upright inner faces of the latter and provided for maintaining the upright wall portions of the waxed bag adjacent the inner upright faces of the fibre carton, horizontally extending pads arranged at the bottom and top of the container, the bottom pad being located with# in the waxed bag and resting thereupon, the wall liners being disposed so that the lower r edges thereof en age the edge portions of the bottom pad, t e top pad having its edge portions resting upon the upper edge portions of the aforesaid wall liners and located in a plane adjacent but slightly below the top of the upri ht walls of ythe crate, the upwardl exten ing portions of the carton and of t e bag being foldable over the upper pad, and a lid for the skeleton crate whereby when closed it causes the crate to encase the carton on the top as well as at the bottom and about the vertical walls of the latter.

2. A shipping container as defined in and by the claim last preceding, which is constructed for receiving a refrigerating medium and which is provided with conduit means leading from the interior 0f the waxed bag through the carton to the exterior of the container.

Signed at Chicago, Illinois, this 23rd day of September, A. D. 1930.
