9 claims. 1m29- 14) meat, food, medicine, beverages or other items which must be kept cool, are often needed for Vstoring and cooling such items. Since such containers are often transported from place to place, as when used to carry beverages for consumption at picnic outings, shipping lish or fowl or transporting medicines, and the like, the containers should be light in weight so that they may be easily portable and adapted to air transport. Furthermore, since they may be subjected to rough handling they should be rugged in construction and capable of being locked closed. They should also lend themselves to stacking. Moreover, since the articles may be stored in the containers for prolonged periods of time before being used, the construction of the containers must be 'such that the passage of heat into the interior of the containers is at an exceedingly slow rate so that the rate of melting of the ice which cools the contents will be as slow vas possible. Containers presently used for containing ice for cooling articles stored in the containers are made of metal and are, therefore, very heavy. In addition, their cost of manufacture is relatively high.

It is desirable, therefore, that a container be provided which is strong but relatively light in weight which will hold ice for prolonged periods of time, 'and which may be easily and economically manufactured, and such are objects of this invention.

lt is also an object of this invention to provide a new and improved container made of paper board or the .like

for containing ice to cool articles stored in the container.

A further object of the invention is to provide a container of the Ycharacter described which may be assembled from a plurality of easily assembled knocked down parts, so that the parts may be shipped in at knocked down condition and may be erected and assembled at the point of use.

Another object of the invention is to provide a carton for containing ice made of corrugated paper board and having spaced air insulating chambers for preventing the passage of heat into the interior of the carton.

Still another object of the invention is to provide a new and improved paper board carton having spaced inner and outer walls providing insulating air chambers therebetween.

A particularly important object of the invention is to provide a new and improved carton in which a moisture impervious paper board or like tank is disposed in a cardboard container, the container and the tank having flaps which space the walls of the tank from the Walls of the container to provide heat insulating air spaces or chambers therebetween.

Additional objects and advantages of the invention will be readily apparent from the reading of the following ICC 2,766,921

description of a device constructed in accordance with theinventi'on and reference to the accompanying drawings thereof, wherein:

Figure 1 is fa perspective view of a container, constructed in accordance with the invention, for containing ice to cool articles stored in the container,

Figure 2 is a vertical sectional view of the container taken on the line 2 2 of Figure l,

. Figure 3 -is "a vertical sectional view 'of 'the 'container taken onthe line 3-3 of Figure 2,

Figure 4 is a bottom plan View of the container,

Figure 'Sis a perspective view of the container with the top removed and with Vportions of the container broken away toshow the tank in position,

Eigure 6 is a perspective view of the moisture impervious tank, and

vFigure 7 is a'plan view of a blank for forming the outer container.

In the drawings, the numeral It? designates a container which is provided with a cover 11 and a moisture impervious tank 12. The container 10 is formed of a blank 13 cut from a sheet of material, preferably cardboard or the like, perforated and scored and ready for assembly. As clearly vshown in Figure 7, the Vcontainer blank vis scored to provide a back wall panel '14, an adjacent end `wall panel 15, a front wall panel 16 substantially identical in size with the b'ack side Wall panel 14, a second end wall panel A17 adjacent the front wall panel, and a ap 18. The various wall panels are outlined by vertical imperforate scored lines .19 which provide for ready folding of the container blank into the rectangular form shown 'in Figures l, 4 and 6, whereby the flap 18 may be secured by staples 26, 'or in any other suitable manner, to the inner surface 'of the back wall panel 14 to form the rectangular walls of the container 10.

Integral bottom closure portions 21 and 22 are formed integral with the back and front wall panels 14 and 16, respectively, and are dened by the imperforate scored fold lines 23 and 24, respectively. The upper bottom closure portion 21 overlies the lower bottom closure 22 (Figures 2 and 3). A pair of opposed bottom closure aps -25 and 26 are formed integral with the end wall panels 15 and 17, respectively, and are defined by the transverse imperforate scored lines 27 and 28, respectively. The bottom closure llaps 25 and 26 are provided with reduced or narrowed end portions 29 and 30, respectively, which are adapted to pass through the perforation or slot 31 in the lower bottom closure portion 22. The reduced end portions 29 and 30 are ea'ch provided with a pair of imperforate scored fold lines 32 which enable the reduced end portions to bebent up and through the slot 31 and'then down to lie between the upper and lower bottom closure portions 21 and 22, as clearly shown in Fgure- 2. It will be evident that when the upper bottom closure 'portion 21 is folded down to abut the reduced end portions, the end portions are held fast thereby, and the bottom structure is positively locked in erected position. It will also be evident that the reduced end portions space the upper and lower bottom closure portions from each other to form an air space or chamber 33 therebetween.

Upper rectangular flanges 34, 35, 36 and 37 are formed integral-*with the Wall panels 14, 15, 16 and 17, respectively, and are dened by the transverse imperforate scoredfold lines 38, 39, 40 and 41, respectively. The

Aupper anges 34, 35, 36 and 37 are provided with fold lines 42 which permit the horizontal portions 43, 44, 45 and 46, respectively, to overlie the upper edges of a rectangular liner having walls 47, 4S, 49 and 5% disposed in the container 10 contiguous to the front, back and end wall panels of the container. The flanges are bent downwardly and inwardly to overlie the upper ends of the liner walls. The liner walls 47 to 50 may be integral l Patented Oct. 16,

and cut from a sheet of material, preferably cardboard or n the like, and scored to allow Vthe walls 47 to 50 to be disposed into a roughly rectangular shape to form the liner.

it will be apparent now'that the rectangular upper flanges will retain the liner wallsY in position and that the lower ends of the liner walls in lturn will prevent the upper bottom closure portion 21 from being bent upwardly to tree the reduced end portions 29 and 30 of "the bottom closure laps 25 and 26.

A pair of elongate tongue members 51 andr52 may be cut outor orm'edin the end wallV panels 15 and 17, Y respectively, `such tongue members extending to the fold lines 42 of the upper flanges 35 and 37. The tongue members vare-adapted to extend upwardly through 'slots 53 and y54 .in the cover 11, then'berbent downwardly around the outer end flanges 55 and 56 of the cover so that the -tree end portions of -the tongues may be 'disposed between the cover anges and the Vend wall 62 and a back wall 63. The front wall 62 is connected to the side Vwalls 61 and 62 by the folded triangular flap vportions 64 'and 65, and the back wall 63 is connected by'fsilnilary l'lap portions 67 68 to such side Walls.

The 'front wall 62 is provided withfa retaining flange 66 and the back wall with a llange v69 which fold outwardly and then downwardly over the upper portions of the triangular flap portionsto retain them in their Vfolded positions, the tank ilange 66 being l'disposed adjacent and abutting the container ii-ange 36 and the tank flange 69 adjacent land abutting the container ange 34 when the tankV is inserted into the container.

It will be seen now that the container anges 35 and 37V space the `end walls 60 'and 61 of the -tank from the liner walls 43 andv 50, respectively, so that heat insulating air spaces or chambers 70 :and 7K1 are formed therebetween. Similarly, the -tanky ange 66 vand the container ange 36 space the -front wall 62 of the tank from'the linerV wall 49, and the tank ange 69 and the container flange 34 space the tank rear wall 63 from the liner wall 47 Vto form the heatrinsulatin'g air spaces or chambers 72 and 73, respectively. The lfour sides and the bottom of the tank being surrounded by the air chambers 33, 70, 71, 72 and 73, in which the air is, of course, substantially at rest, the air'chambers insulate the tank and reduce iiow of heat into the tank to melt the ice which may be contained in the tank.

and lthen inwardly and upwardly inside the cover flanges v A rectangular moisture impervious cover plate 74 running along the front and back walls of the tank and container. The cover 11, of course, ioverlies the cover Vplate 74 and Vholds it in place, the tank being of such Yheight that the coverV plate Yis disposed between the liner walls and between the cover and the anges 66 and 69 and the upper edges of the end walls 60 61 of the If desired, a layer of foil metal, such as aluminum or Vtin lfoil, may be provided to cover the inner surfaces of l tively broad, iirm supporting surfaces for the cover plate the tank 12 to provide -moisture imperviousness and in-V `creased insulating value to the tank.

The container may be easily assembled by.V bending the Wall panels 14, 15, 16 iand 17 in rectangular form and then `stapling the panel diap 18 to the rear wall panel 14. The upper bottom closure 21 is bent inwardly between the wall panels and then the lowerrbottom closure 22 is bent perpendicular to the wall panels. The bottom closure flaps 25 and 26 are then bent inwardly 'and their reduced end portions 29 and 30 are passed through the slot 31 and bent downwardlyto lie over the lower bottom closure 22. The upper bottom closure is then moved into parallel relationship with the lower bottom closure portion 22 and over the reduced end port-ionsy of the closure flaps. The liner with its walls 47, 48, 49 Iand 50V is then insertedY into 'thecontainer and the anges 34, 35, 36 and 37 are bent over and down over the upper portions lof the liner walls. The

tank 12 is then placed in the container, ice 'and lthe articles to be cooled are placed in the tank,V the moisture- Vproo'ted cover, 74 Vis placed over the tank, and iinally 'the Y `cover 11 isY placed in position on the container, the tongue members 51 and 52 being folded around thecover flangesltohold the cover 11 on the container.H f

It will thus be seen that a container for holding ice and articles to be cooled has been provided which is made of cardboard or the like, and is easily assembled from a plurality of scored blanks which lform a container 10, liner walls, and a moisture-proof tank 12. It will also |be seen that the container is light in weight but of strong, rugged construction', the liner walls rein-forcing the container, and that the contents of the tank :are well insulated by means of the air chambers beneath and on the sides of the tank which minimize the passage of heat from without the container into the tank.
