REFRIOERATED PORTABLE BOTTLE VENDOR Original Filed Oct. 25, 1940 2 Sheets-Sheet 2 and outer walls are in co prises a base metal contact between walls 40 and I2 and either floor 28 or rack 26. No metal part of container 35 that yis capabler ofA heat transfer isin contact with any portion of case I2 or its component parts and therefore, the cooling of the bottle 'compart- Having thus described the invention, what is claimed as new and desired to be secured by Letment is effectively accomplished without loss of y cooling medium.
The form of container 56 illustrated in Fig. 6 is slightly diierent from that just described in that it has an open upper end, and the gas formed by sublimation of the dry ice,rspills over the edge o1' container 56 at the topthereof. An even and desirable heat transfer is established throughout the entire length of container 56, however, because sheet metal walls 58 are brought together along four vertical lines to present a metal-tometal relation capable of heat transfer. laterally toward bottles il in the circumscribing path which skirts container 56.'
For the reasons above mentioned, with respect to container 36, the form of container 56 shown in Fig. 6 should have a base 60 of insulating material that may be pressed into well 30.
s2 umstratea in Fig. 5 of wood or other insulating materiali! from one side of which extends inner and -The form of container outer walls 66 and 68 respectively, having insu1at ing material 10 packed therebetween. Inner wall 56 projects upwardly, outwardly and thence downwardly along the outer surface of outer Wall 42 to present an uninterrupted sheet metal memaged goods surrounding scribed, a closed case; a floor ber that is capable of' conducting heat units.
Heat exchange between the air surrounding botv tles il and the dry ice within container 62 therefore, is insured.
The length of downwardly projecting portion 12 oi' wall 66 may be varied to suit conditions for 4the longer this portion`12 is made, the greater the heat exchange will be. Either of the three forms of containers shown in Figs. 4, 5 and 6 is usable in bottles I l case I2 and will adequately cool al1 therein.
ters Patent is:
1. In a vending machine of the character dewithin said case a rack icr packscribed, a closed case: a oor having a well formed therein; aged goods on the iioor surrounding the well; and a refrigerant cotainer having a base seated in said well, said'container having inner and outer metallic walls contiguous to each other at intervals along vertical lines to effect transfer of heat radially from the container toward said rack.
2. VIn a vending machine of the character described, a closed case: a floor within said case having a well formed therein; a rack for packcontainer for dry ice well, said container having radial outlet porta near its base for escape of gas created through sublimation oi the dry ice.
3. In a vending machine of thecharacter described, a closed case; a. floor within said case having a well formed therein; a rack forpackaged goods surrounding the well; and a container for dry ice having a base of non-conducting material removablyk 'seated in said well; said container having spaced inner and outer metallic walls and insulation therebetween, the inner walll projecting outwardly and downwardly along a partial length of the outer wall for radial heat exchange between air surrounding the packaged goods and dry ice within said container.
4. In a vending machine of the character dewithin said case having a well formed therein: a rack for packaged goods on the iloor surrounding the well; 'and l a refrigerant container having a base of nonconducting material seated in said well, said container having'an inner metallic wall of angular cross section andan outer metallic wall of circular cross section in contiguousv relation with angles of said inner wall to effect transfer or heat:
