This invention relates to refrigerated containersand particularly to containers in which frozen foods andother commodities'may be transported or stored in refrigerated condition.
An object of the invention is to'provide a light weight, inexpensive, shipping container which may be readily'collapsed'for return shipment or compact inactive storage, and onewhich may be quickly set up and'placed in refrigerated condition' for active service;
Another object of the invention is the provision of a container of the character referred to, which isfcon'structed with interchangeable members which may be readily replaced in the event of damage in transit.
A furthero-bject of the invention is the provision of a collapsible shipping container which is'adapted to employ dry ice as the refrigerating medium, the container being so constructed and arranged that the sublimation of the dry ice is regulated and temperature control is eifected.
. It'is an objectof the invention to provide a devicehaving self-contained refrigerating means, whereby less than car load lots of frozen foods and the like, may be shipped'and stored, independent of the usual large scale equipment heretofore required to' be employed for such purposes.
"Another object of the invention is theproVisiOnv of a device of the character referred to which is Ii assembled from disconnected sections or panels and held together by straps or other flexible elements, whereby varying degrees of air tightness may; be effected between the'several sections.
Another object of theinve'ntion is the provision of a" device of the character referred to which -may be employed as a container for shipping perishable merchandise to a destination point,
utilizing dry ice as the refrigerant enroute, and at the point of destination a portable mechanical refrigerating machine can be set in to replace the dry ice, and thedevice can then be employed indefinitely as a storage container. V
Theforegoing objectsand other advantages of the inventionwill appear as the description proceeds, reference being made from time to time to the accompanying drawings, in which:

' Referring now'more particularly theldra'w i ings, it will be understood that in the embodiinentherein disclosed (Figs. 1 and 2), my im-' proved shipping container isjmade up'of side walls :2, end walls l3, top, bottom l5, top shell I6 and bottomshell l1, all of whichare constructed and assembled ashereinafter described. The shells l6 and I 1 are preferably provided with metal reinforcing corners Ilia. The side walls IZ (Fig.6) are preferably constructed of several thicknesses of heat insulating material includ ing an outside layer [8 of substantially hard fibrous material, such as fiber board or the like. Securedto the inside of the layer 18 by any suitable'means, such as gluing or the like, is a second section of insulating material H] which is as sembled in the following manner. Two U-shaped shells of corrugated cardboard 29 and 2! (Fig. 7)
are arranged to telescope one another with the corrugations of one shell running at right angles to the corrugations of the second shell, to effect a rigid construction} The void betweenthe shells 26 and ll is preferably filled With kapok 22 or other effective heat insulating medium. A third section 23 (Fig. 6) is secured to the intermediate section l9 by any suitable means. The section 23 is fabricated and constructed in the same manner as the section I9' hereinabove described. In order to increase the rigidity of the side Walls,
7 I provide reinforcing members 25a, which are preferably formed of a corrugated fiber board,
bent and rebent to form a plurality of tunnel i members as shown in Figs. 7 andf1 3} The tune nel members 21a of the section I9 are disposed in a vertical position, and the tunnel members 2la of, the section 23 are disposed in a horizontalposition. The sides of the tunnel members; ltd
are secured to the inside Walls iii'the shells 2| by The.
means of glue or other suitable means. voids of the tunnel membersil arefilled with kapok 22, or other effective heat insulatin'g' ma terial, as hereinabcve described. Secured to the. id 0? th walls. an like! m a s f apl 23'; or othersuita ble meansfis of.

" In 'Ffig; 12, 1 illustrate a modified form of mechanism for controlling the'flow of CO2 gas- 25 aspreviously described. Superimposed on the fioor member 59 is a'fixed panel lifland two slidable panels 6| and 62. i The panels 5i and 62 are provided with cut-outs 63, which are adapted to communicate with the openings-in the tunnels 25. The slidable panels El and 62 are joined by means of a link 64 which is pivoted in the center as at 65 and slotted at the ends as at fi lajwhich slots are adapted to engage pins Ma an 62a. The link fi l maybe provided withpo'inters'ili, which are adaptedto co-operate with calibrations 67; whereby different degrees of'a'djustment of the panels GI and 82 ma be registered. The panel 60 ispreierably covered witlra heat insulating medium such as felt 60a. .Itw'ill be noted that the tunnels '25 positioned-at the ends remain open at all times, whereas the tunnels 25 positioned along the sides may be covered and uncovered by-means of'the slidable panels 6i and 62, whereby the flow of CO2 gas and air in the side tunnels 25 may be controlled to effect varying degrees o-f 'temperature in the storage compartment.
In Fig. 13, I illustrate another modified for'm of container which may be constructed in'general of three nesting cartons 68. 69 and '70; each of which is provided with a closed bottom and sealed corners. The outside carton 68. is preferably made of a' substantially stronger material than the interior cartons 69 and Hi. In some applif) cations it may be desiredfto have the exterior carton made ofa fireproof material. The intermediate carton St is preferably l in'ches smaller in all of itsdimensionsjthan the outside carton G8, and the inside carton i0 ,is correspondingly smaller than the intermediate carton B9.
interposed between the wallsof the carton 68 are reinforcing tunnel-like members II, which are formed as previously described. Theftunnellike members "H are preferably secured to the outside surfaces of the walls of the carton'69 in a similar manner. The tunnel" members H.
which are interposed between the wallsofthe cartons Edandfifi, are preferably'disposed: in a vertical position, whereas the tunnel members "ll interposed between the walls of thecartons 69 m and Iii, are preferably disposed in a horizontal This insuresa rigidconstruction for the device. The voids betweenthe wallsof the several cartons and the voids in the tunnels ,are.
filled with any. suitable heat. insulating .r'nate-j The tunnel members 25 are secured to the inthe bottom shell I1, and then introducing one end wall'l'3 and the side Wallsl2, leaving the second end wall l3 to be set in position after the shelf 39 is inserted. After the walls and the shelf 30 are in position, the horizontal straps 36 are made fast and the container is ready to be loaded with frozen foods or other perishable commodities.
When the storage compartment is sufliciently filled, the floor 26 of thecooling compartment and the'control panels 44 are then placed in position on the tunnel members 25. then set in place and the control panels are ad justed to the proper position to effect the desired temperature control in the storage compartment. The device is now ready for the dry ice or'other refrigerant. When the container is charged with the'proper amount of refrigerant, the top member- [4 is set in position and the top shell 16 is set in place, the vertical'straps 39 are then made fast and the device is ready for shipping.
Having described my invention, what I claim and desire to secureby Letters Patent is;
15A refrigerating container for the shipment and storage of frozen foods and the like, com
