Patented l5, 1929- @UNITED STATES PATENT OFFICE Y RIDGWAY RKENNEDY, OF"PHILADELPHIA, PENNSYLVANIA, ASSIGNOR T0 .ABBOTTS DAIRIES, INC., F PHILADELPHIA,PENNSYLVANIA, A CORPORATION Ien-CREAM PACKAGE Application lfiled. November 27, 1928. Serial No. 322,118.

My invention'is aportable vendible package adapted for elliciently and safely refrigerating frozen confections by solidified gasef ous refrigerant which, in absorbing heat,

'5 gives olf vapor developing considerable pressure in a tightly enclosed container.

My invention is designed to provide a simply made and readily assembled package consisting of one or more rectangular boxes containing a block or blocks of the confection and an outer container or receptacle, preferably cylindrical, housing the box or'boxes and a refrigerant.' The diameter of the inside of the outer container is preferably so proportioned to the size of the inner boxes that passages of arcuate cross section, are formed on all four sides of the boxes to permit free circulation of the refrigerant gas.

The joints of the outer container are normally suiiciently tight to prevent or minimize leakage of warm air into the package but suliiciently yielding to permit escape of gas generated from the refrigerant when the lpressure within the package rises slightly above atmospheric. The escaping refrigerant gas forms a layer of cold gas between inner and outer laminas of the outer container and. checks ingress of warm air to the interior thereof. i

A further obj ect of my invention is the provision of a package of which either end may be treated as the bottom and the opposite end as a lid which may be removed without disturbing. the refrigerant or confection within the container.

In the' preferred embodiment of my invention, a cylindrical carton of laminated faced corrugated board has telescoped on opposite ends thereof duplicate casings or closuresconsisting of anged cylinders having therein yielding end disks formed of faced corru' gated board, the number of disks being preferably greater than the number of laminations of the corrugated board in the cylinder. When the ends of the carton-are pressed against the disks, a close joint is normally formed preventing leakage of warm air into the package. When, however, the evolution of gas within the package raises the pressure slightly above atmospheric, the end disks companying drawings in illustration of a yield slightly to the pressure, thereby unseating them from the edges of the carton and opening the joints so that gas escapes outwardly and passes between the outer walll of the carton and the inner walls 0f the external casings. The edges of vthe external casings are preferably slightly spaced from one another at the middle of the package to permit escape of gas. 1

The characteristicfeatures and advantages of my improvements will more fully appear from the following description andthe acpreferred embodiment thereof. l

In the drawings, Fig. 1 is a broken perspective view of an ice cream package embodying my improvements; Fig. 2 lis a longitudinal sectional view thereof on a reduced scale; and Fig. 3 is a transverse sectional view 'taken on the line 3 3 of Fig. 2.

As illustrated in the drawings, the cylindrical casings l, preferably rolled from paper board, have fixed to the edges thereof thereenforcing flanges 2 forming seats for disks 3 of faced corrugated paper. The peripheries of the disks 3 fit closely in the'casings 1 so as to form tight joints therewith.

A cylindrical carton 4, preferably wound I from a plurality of laminations of faced corrugated paper fastened along a longitudinal joint, as y rivets, staples or adhesive,'is telescoped within and makes a close fit with one of the casings 1. The edge of the carton 4 normally closely abuts against the upper disk 3 in the telescoped casing. A refrigerant 6, such as solidified carbon dioxide gas, is placed in the carton and bricks of ice cream contained in square boxes 7 are deposited on the refrigerant. A second block of refrigerant 6 is placed on top of the ice cream boxes and the container is closed by telescoping the secand casing 1, containing disks 3, over the open end of the carton. As willbe observed from Fig. 3, the sides of the ice cream boxes are surrounded byvpassages of arcuate crosssection permitting free circulation of refrigerant gases.

When the package is originally closed, the edges of the carton 1 make close contact with the surfaces of disks 3 and prevent ingress of warm air into the package. When, however, carbon dioxide gas begins to form, the pressure of the gas unseats the yielding disks from 'the edges of the carton 1. The gas is thus permitted to escape between the walls of the cylinders 1 and 4, the former being preferably made of unyielding material and the latter of yielding material. The gas passesY out through the narrow mouth 8 between the edges of the disks 1.

Having described my invention, I claim:

1. A. frozen confection packa e consisting of cylindrical casings telescope upon a carton of corrugated sheet material, said carton having its ends covered by disks seated in said casings, and a rectangular confection box housed within said carton and having its sides surrounded by refrigerant circulating passages of arcuate cross section.v

2. 'A package for a gaseous refrigerant and foodv product comprising a cylinder of corrugated sheet material having open ends, casings telescoping over opposite ends of said cylinder and having therein disks of corrugated sheet material yieldingly sealing the ends o f said cylinder.

3. A package for a gaseous refrigerant and a food product consisting of an .open ended carton of insulating sheet material, closures vof yielding insulating material engaging the ends of said cartoon, and a flanged casing telescoped over each end of said carton and having their inner edges slightly spaced from one another when fully telcscoped on said carton.

4. A frozen confection package consisting of similar cylindrical casings telescoped upon opposite ends of a carton of corrugated sheet material, corrugated paper disks seated in said casings against the edges of said carton, solidified gaseous refrigerante at opposite ends of said carton, and a rectangular confection box within said carton between said refrigerants. y

In testimony whereof I have hereunto set my hand this seventh day of November, 1928.

R. R. KENNEDY.
