RECEPTACLE FOR FROZEN PRODUCTS Filed Feb. 1, 1930 Patented June 21, 1932 UNITED STATES PATENT OFFICE WILLIAM R. WILLAUEB, OF PHILADELPHIA, PENNSYLVANIA, ABSIGNOB TO Hm- THON PAPER HILLS COMPANY, 01' ROTHSCHILD, WISCONSIN, A CORPORATION OF WISCONSIN BEOEPTAGLE FOR FROZEN PRODUCTS- Application filed February 1, 1980. Serial 110. 425,228. 4

This invention relates to a receptacle for frozen products, such as, ice-cream or the like; and more particulagly .to a receptacle for refrigerating such pr ucts during transportation or storage.

My invention, in its broadest aspect, contemplates the use of a double-walled container for frozen products and a tube for a solidified gaseous refrigerant centrally positioned in the container, the tube and container being interconnected so as to provide for a circulation of the refrigerating medium after conversion to the gaseous state through the space between the double walls of the container to thus completely surround the frozen products with said medium.

It is accordingly an object of this invention to provide a refrigeratin receptacle for frozen products wherein a so id refrigerant that is normally gaseous is employed and wherein the receptacle is so constructed as to provide for the insulation of the same by means of such refrigerant when converted into the gaseous state.

Itisafurther object of this inventionto provide a refrigeratin receptacle for ice-cream and the like where y such products may be efiiciently and readily transported and stored without a substantial change in their physical form.

Other and further important objects of this invention will become apparent from the following description and appended claims.

Referring now to the drawing which discloses a preferred form of my invention:

Figure 1 is an isometric view of my receptace, parts thereof being shown in section an Figure 2 is a detail in isometric of a portion of the paper board plies forming the end members of said recptacle. 1

The improved receptacle of this invention indicated generally by the reference numeral 1, comprises a container '2, of sulfurized fibre board or the like, for the frozen products.

The ends of the container 2 are closed by friction closures 3 and 41, each of which have a flange 5 for gripping the ends of said container. The closure members 3 and 4 are also made of sulfurized fiber board.

The inner face of each closure 3 and 4 is provided near its center with a cup-shaped member or socket 6, secured thereto by means of brads or similar conventional fastening means 7. An inwardly extending flange 8 on saidmembers 6 fits about and frictlonally grips the open ends of a tubular refrigerant rece tacle 9 to thereby close the ends of said tube and support the same in said container 1. The tube 9 1s adapted to be filled with a solidified gaseous refrigerant, such as solid carbon dioxide or the hke. The socket members 6 and end members 3 and 4 are provided with communicating openings or passages 10 for a purpose to be later described.

Surrounding the frozen products container 2, is a jacket or casing 11, said jacket bein composed of a plurality of plies of corrugated fibre board 12 and 13, as clearly shown in the section C in the lefthand side of Fig. 1. Each ply of said fibre board comprises a wall 14 having a corrugated sheet 15 secured thereto, so that when the plies are assembled to form a jacket as shown in Fig. 1, the spacing provided by the corrugated sheets 15 will form open ended passages extending the full length of the jacket 11. The ends of jacket 11 are closed by means of end disks '16 and 17 which fit against the end members of container 2. Said end disks are securedto the jacket 11 by means of strips 18 of sealing paper or the like.

The end disks 16 and 17 are also constructed of a plurality of plies of corrugated fiber board in the same manner as the plies forming the body portion of jacket 11. When the end disks are secured on the jacket 11, the passages occurring in the main body portion of the jacket between the container 2 and the wall 14 of the outer ply of the jacket will overlie the corrugated sheet 21 of the inner ply 20 of said end disks. Said corrugated sheets 21 are perforated as shown at 26 in Fig. 2 as is each of the walls 22 oftheinnerplies20. The interior of tube 9, by means of the apertures 10 in the sockets 6 and perforations 26 in the corrugated sheets 21 and walls 22 of the jacket end members is thus placed in communication with the above described passages in the jacket body 11 so that when the solidified carbon dioxide in tube 9 takes up heat from the frozen products in container 2, and is converted to a gas, the gas will clrculate from said tube 9, to and through the bottom disk, of the jacket 11, through the jacket 11 and into the top end disk of said jacket. In this way the container 2 and 1ts enclosed frozen products will be completely surrounded by said gas, which is in itself an insulator, and thereby reatly increase the refrigerating efiiciency of the receptacle.

In assembling the device, it is merely necessary to roll a pair of plies of corrugated fiber board over the container 2, to form the jacket 11. The lower end disk is then placed on said acket and secured thereto. The container 2 is then filled with frozen products and tube 13 with a stick of solidified carbon dioxide. The cover 3 is then placed over the container 2 and the upper end disk over the jacket 11.

The device so formed will comprise in effect a container composed of spaced apart walls, the space between the walls containing an insulatmg gas.

By constructing the device in this manner the as space required to retain the carbon dioxi e is materially reduced. Furthermore,

- the efliciency of the refrigerant is augmented by producing the lowest temperature of the frozen products at the center of the same.

It has been calculated by employing my device, that at the average summer heat of 75 F. a five gallon can of ice-cream, leaving the storage room at 0 F. will be retained at approximately that temperature for a period of eighteen hours.

It is, of course, to be understood that details of my construction may be varied without departing from the spirit of the invention disclosed and, hence, I do not purpose to limit myself except as is necessitated by the prior art.

I claim as my invention: Y

1. A refrigerating device for frozen products comdprising a container having spaced apart si e and end walls with a gas space between said spaced walls, a tube for a solidified gaseous refrigerant centrally positioned in said container and extending the full length thereof, said tube and gas space being interconnected whereby said refrigerant when converted to the gaseous state will circulate from said tube into said gas space.

2. A receptacle for frozen products comprising a container for said frozen products, a tube for a solidified gaseous refrigerant positioned centrally in said container, means for closing said container and tube, a jacket surrounding said container, said jacket being formed of a plurality of plies of corrugated fiber board arranged one on the other to provide gas passages in said plies, said tube and gas passages being interconnected whereby said solidified refrigerant when converted to tube into said tainer walls whereby to the gaseous state will circulate from .said
