POCKET LIQUID COOLING DEVICE Original Filed Nov. 22, 1955 IN V EN TOR.

United States Patent 2,900,808 POCKET LIQUID COOLING DEVICE Wensan Wang, Tokyo, Japan' Original application November 22, 1955, Serial No. 548,488, now Patent No. 2,805,556, dated September -10, 1957. Divided and this application May 14, 1957,

Serial No. 659,166

4 Claims. (Cl. 62-294) This application is a division of application Serial No. 548,488, filed November 22, 1955, now Patent No. 2,805,556, and relates to a pocket liquid-cooling device.

An object of the invention is to provide a liquid cooling device of the pocket type in which the liquid may be maintained in a cooled condition for a lengthy period.

Another object of the invention is to provide a liquid cooling device of the pocket type in which the liquid is cooled by the expansion of a refrigerating gas.

Other objects and advantages of the invention will become apparent from the following description taken in conjunction with the accompanying drawings, in which:

Figure l is a top plan view of one form of this invention.

Figure 2 is a vertical sectional view through Figure 1.

Figure 3 is a bottom plan view of Figure 1.

Figure 4 is a fragmentary enlarged sectional view taken substantially on the line 44 of Figure 2, and

Figure 5 is an enlarged fragmentary sectional view taken substantially along the line 5--5 of Figure 2.

Referring to the drawings in detail, a receptacle designated generally comprises a hollow cylindrical body 12 carrying adjacent one side a handle 14. The body 12 is lined with a suitable thermal insulation 16. Positioned within and spaced from the wall 22 of the receptacle 10 is a shell 17, the space between the shell 17 and the wall 22 of the receptacle 10 defining an expansion chamber 18. A cooling coil 24 having a plurality of spaced convolutions is positioned vertically within the shell 17 and has the uppermost one of the convolutions in communication with the expansion chamber 18 adjacent the upper end thereof as at 20. The lower end of the chamber 18 is vented as at 26 to atmosphere. Carried by the lowermost convolution of the coil 24 and extending radially therefrom and through the expansion chamber 18 is a nipple 28. Extending transversely across the body 12 adjacent the lower end thereof is a cartridge chamber 30, the underside of which opens downwardly and is closed by a hinged cover 32 which carries a bolt 34 that enters a skirt 36 carried by and extending downwardly from the bottom of the receptacle 10. Extending into the receptacle 10 and communicating with the cartridge chamber 30 adjacent one end thereof is a recess 35 which communicates through a passage 37 with a duct 38 that, in turn, communicates with the nipple 28 so' as to establish communication between the cartridge chamber 30 and the expansion chamber 18. A valve 40 is carried by the body 12 and extends through the duct 38 for a purpose to be more fully hereinafter described. Seated inthe recess 35 is a gasket 42 which is adapted to engage the neck 44 2,909,808 Patented Aug. 25, 1959 carried by the body 12 and extending into the passage 37 is a needle 48 having a passage 50 extending therethrough which communicates with the passage 37 at its junction with the duct 38. Extending through the body 12 in axial alignment with the passage 37 is an internally screw threaded opening 52 in which is threadedly received a pressure plug 54 carrying wings 56 by which the plug may be turned to cause it to advance into contact with the cartridge 46, and move it in a rectilinear path through the cartridge chamber 30 and into contact with the needle 50 to puncture the cartridge and permit the contents thereof to flow through the duct 38 into the expansion chamber 18, to cool the contents thereof. In the preferred form of the invention, a cover 58 is hingedly connected as at 60, to the body 12 to close the upper open end of the receptacle 10.

In use, it will be evident that when employing the device of the invention, the punctural cartridge 46 containing refrigerant is deposited in the cartridge chamber 30 through the bottom thereof after which the cover 32 is closed and bolted into place, as illustrated in Figure 2, it being understood that the plug 54 has been turned to cause it to retract and allow room for the insertion of the cartridge. With the cartridge in place, it will be evident that when it is desired to refrigerate the contents of the receptacle 10, the plug 54 is turned to advance the cartridge into contact with the needle 50 which punctures the cartridge and permits the contents thereof to flow through the passage 37 and duct 38 into the expansion chamber 18. The rapidity with which the refrigerant enters the expansion chamber 18 may be regulated by the valve 40 and as the refrigerant expands in the expansion chamber 18, a cooling of the contents thereof will be effected. Upon expansion of the refrigerant, it is permitted to escape through the vent 26 to atmosphere. Obviously, as the cartridge 46 is advanced into engagement with the needle 50, the neck 44 thereof will be firmly pressed into engagement with the gasket 42 to efiect a fluid tight junction between the cartridge and the wall of the recess 34.

What is claimed is:

1. A pocket liquid cooling device comprising a thermally insulated lined receptacle having an open top, a shell positioned .within and spaced from said receptacle, the space between said shell and said receptacle defining an expansion chamber, a cooling coil having a plurality of spaced convolutions positioned vertically within said shell and having the uppermost one of said convolutions in communication with said expansion chambenand a nipple carried by the lowermost convolution and extending through said expansion chamber and having the free end in communication with a duct formed in said receptacle, there being a passage in said receptacle having one end in communication with said duct and having the other end in communication with a recess formed in said receptacle, said receptacle having a cartridge chamber therein which communicates with said recess, a puncturable refrigerant containing cartridge mounted in the cartridge chamber for movement in a rectilinear path therein, and a needle extending into the passage and carried by said receptacle and extending in the path of movement of the cartridge for puncturing said cartridge upon its advance toward said needle and delivering refrigerant from said cartridge through the recess, passage, duct, and convolutions of the coil, into the expansion chamber.

2. The pocket liquid cooling device according to claim 1 wherein said cartridge chamber opens through the bottom of said receptacle, and an openable and closable cover closes the open bottom of said cartridge chamber.

3. A pocket liquid cooling device according to claim 1 which includes in addition means carried by the receptacle and extending into the cartridge chamber for engaging the cartridge and advancing it toward the needle.

4. A pocket liquid cooling device according to claim 1 which includes in addition means carried by the receptacle and extending into the cartridge chamber for engaging the cartridge and advancing it toward the needle, and a References Cited in the file of this patent UNITED STATES PATENTS 735,403 Osborne Aug. 4, 1903 2,155,956 Planer Apr. 25, 1939 1 2,475,755 Pearson July 12, 1949 2,746,264 Keyes May 22, 1956 FOREIGN PATENTS 26,771 Great Britain Dec. 19, 1898
