PHILIP S. CAMPBELL, 0F HOUSTON, TEXAS, ASSIGNOR 0F ONE-HALF T0 MARCH CUL- MORE, 0F HARRIS COUNTY, TEXAS CONTAINER Appncation ined February 1, 1929. serial No. 336,729.

This invention relates to new and useful i-mprovements in a container.

One object of the invention is to provide a container ot' the character described specially designed for containing perishable merchandise such as fruits and the like which must be .kept cool to prevent decay.

Another object of the invention is to provide a container for a. compartment for the articles to be preserved and also havingv a compartment for a frigid substance to cool the compartment containine the fruit or other articles to be preserve A further feature of the invention resides in the provision of a container which is very compact and wherein the articles of merchandise to be preservedas well as the refrigerant may be contained as well as inclosed and which is convenient for storage or shipment. y

With the above and other objects in view the invention has particular relation to certain novel means of construction, arrange'- nient of parts, operation and use, an example ot' which is given in this specification and illustrated in the accompanying drawing wherein:

Figure l shows a perspective View of the container shown in open position.

Figure 2 shows a sectional view thereof.

Figures 3 and 4 show top and bottom `views of the cover.

Figure 5 shows a bottom plan View of the inside cover plate.

Figure 6 shows a lan view thereof, and Figure 7 shows a p an view of the outside cover plate. l

Referring now more particularly to the drawing, wherein like numerals'iof reference designate similar parts in each of the figures, numeral l designates abox like container composed of any suitable material, preferably of wood or other non-conducting material and vhaving thick walls and the numeral 2 designates generally the cover which is hinged to said container. The container is designed to contain the articles to be stored .or shipped. -In the cover 2 there is a compartment 3 to receive a refrigerant as 4. 'I' his refrigerant is a chemical prc duct commonly known as dry ice which melts, or dissolves very slowly. The cover 2 has a sheet metal inside plate 5 having a plurality of depending tubes 6 and the plate 5 is lined with a thin sheet preferably formed of balsam wood, having the perforations as 8 aligned with the tube and the refrigerant rests on said sheet. 'lhe margins of the plate 5 and its lining sheet 7 are countersu'nk into the cover 2 and suitably secured thereto the cover 2 has an outside removable cover plate 9, counter sunk into and suitably secured to the cover 2 and which is provided with the vents 1U, l() and the handle 11. The cold gas in the chamber 3 passes down through the tubes and is distributed throughout the contents of the container 1, the surplus fumes passing out through the vents 10. The tubes 6 are specially provided for conducting the CO2 gas well down into the container 1 and may be made of any length for this purpose.

lVhile I have shown what I now consider to be-the preferred form of the invention it is obvious-that mechanical changes may be made therein and equivalents substituted for the part-s shown within the principle of the invention.

IVhat I claim is A container having a storage compartment, a cover therefor, said cover having a refrigerant compartment, the bottom of said refrigerant compartment beingvformed 1of a perforated metal plate having a wood lining, tubes. aligned with the perforations of said plate and depending into the storage compartment, said cover having an outside removable cover plate forming the top of the refrigerant compartment and having vents therethrough.

In testimony whereof I have signed my name. i

PHILIP S. CAMPBELL.
