Description

I Aug. 19, 1947. R. L. STEVEN HEATED FOOD PACKAGE Filed May 12, 1944 r INVENTOR. RAY 1.. STEWN ATTORNEY Patented Aug. 19, 1947 UNlTED STATES PATENT OFFICE 2 Claims.
This invention relates to article packaging and more especially to a package for food containers adapted to be heated prior to opening the food container.
An object of the invention is to provide a simple, practical and inexpensive food package of the character described.
Another object is to provide a food package having exothermic properties upon the addition of water to a chemical therein contained.
An additional object is to provide a food package adapted to be self-heating and adapted to receive standard food containers.
Other objects and advantages will appear and be brought out more fully in the following specification, reference being had to the accompanying drawing wherein:
Fig. 1 is an elevation View in central section of an embodiment of my invention.
Fig. 2 is a perspective View of the expansible wall shown in Fig. 1.
Fig. 3 is a view similar to Fig. 1 showing the lower portion of a modified form of the invention, and
Fig. 4 is a sectional View taken along the line 4-4 of Figure 3.
Referring more particularly to the drawing I show a food package comprising a shell lil having spaced wall portions ll adapted to retain therewithin a heat insulating material l2 such as asbestos or the equivalent, there being an annular opening 13 at the bottom for interfitting engagement with a bottom disc M of a construction similar to shell I6 and adapted to provide support for a supporting disc member I5. Disc I 5 has an annular flange l5 and a space I! provided with lateral openings or passages l8 as shown. A standard food container 1 9 which may comprise a metallic can or the like is adapted to be positioned on flange l6, and a substantially cylindrical expander 20 is positioned between shell Ill and container l9, and provided with a tongue and groove connection iii to permit the wall portion thereof to expand. A space 22 is provided between shell I!) and expander 20 to provide room for expansion of the expander and within the expander is a cartridge or sleeve 23 composed of lime or other suitable chemical which, when water is added thereto, will generate heat which is conducted into can I9 but is prevented by the insulating properties of shell l6 and disc l4 from escaping.
A cover receptacle 24 is shown as having a flange portion 25 for the top of shell l9 and an annular flange 26 positioned above cartridge 23. A plurality of holes 2! are formed through receptacle 24 providing passages for the flow of water 28 which may be placed in receptacle Z4 and conducted to and into the space containing the chemical 23. Cover 24 is provided with a neck 29 having a bore 30 which gives access to the top of can l9 for puncturing with a suitable tool in order to permit the escaping of air pressure developed within the can I9 when heated.
The operation-of the invention as thus described should be clear. The package in dry condition is readily transportable and adapted to receive any standard can [9 suitable for the size of the package, and when it is desired to heat the can a quantity of water is placed in receptacle 2 which passes through holes 21 into the chemical compartment 23, forming an efiervescing solution which is exothermic, a portion of which passes through passages l8 into space H, thus heating the side portions and bottom of the can. This efi'ervescing solution expands and thus expands expander 20 into space 22. Before or during the heating process the top of the can may be punctured by a sharp pointed tool inserted through neck 29 to permit the escape of air pressure within the can.
The package may be used repeatedly by pressing the bottom disc l4 upwardly to remove the spent cartridge 23 which may be replaced with a fresh cartridge.
In Figs. 3 and 4 I show a modified form of the invention which comprises a shell 3| of any suitable thin walled material on a base 32 which latter supports a spacer block 33 for support of a can 34. Block 33 has a plurality of lateral passages 35 which lead between a central chamber 33a and an external space. Immediately within shell 3! is a corrugated Wall 36 positioned in an expansion chamber or space and an exothermic cartridge 31 is positioned between wall 36 and can 34.
This package may be made exothermic in substantially the manner shown in Fig. 1 by suitably supplying water to cartridge 31 which becomes an efiervescent solution, a portion of which passes through passages 35 into chamber 330. below can 34, the expansion of which solution may occur in the space formed by the envelope of corrugated wall 36 or by deforming the same.
Having described my invention what I claim is:
l. A heated food package as described comprising an insulating shell having a cavity to receive a food container, a food container in said cavity, a chemical cartridge around said container, a wall forming an expansion chamber between said cartridge and said shell, and a cover and receptacle element for water having aperture means to convey water to the chemical cartridge, said cover having a neck adapted to expose a portion of the top of the food container for puncturing.
2. A heated food package as described comprising an insulating shell having a cavity to receive a food container, a food container in said cavity, a chemical cartridge around said container, a Wall forming an expansion chamber between said cartridge and said shell, and a cover and receptacle element for water having means to convey water to the chemical cartridge, said shell having a removable bottom Wall section to facilitate replacement of said chemical cartridge and food container.
