rlhis invention relates generally to conteiners but more particularly to e. unique and novei reirigeretory conteinera @ne o' the objects oit ti 'e invention is the provision of e combined refrigerant container and refrigerator chamber vvith speciel reiference to the smell or portable type.. v y Another object is to provide e. enit the ebove type that permits of tree end cosy so lo cess to the interior ot both chembers.

Another end more specio object is to prou vide e, container o the vecuurn type, ing the above features, end one thet may used in. e manner to utilize the uil odventeges of the vacuum or when not in use to compnet the unit by collapsing the vecunni providing section.

Another object is the provision oie oonvertible r rigeretory conteiner in which the refriferent either surrounds the refrigerator chemer or is surrounded by it, as desired.

A stiil further object is to provide e re- 'rigeretory container of the ebove type pecu lierly edepted Qtouse solid carbon dioxide es the reirigersnt.

it will be epperent by reference to the iollowing speoiiicntion end claims teiten in connection 'with the accompanying drevvings how ll ettein these and other objects, which ere bronght out more fully hereineiter.

Referring to the eccompenying drawings,

Fig. l is e side elevation of one forni of the invention;

'which generally would be used es the refrigt container and placed es shown Within 'the container provided to hold the liquid or materiel to be reirigereted.

rThis construction provides 'the vacuum specs 8, refrigerator chamber 9 end refrigernnt conteiner specs if). n

@ne end oi the container 'if' the opening il therein to eliovv 'for teccessi to the interior thereof end e screw threr-.ded or other suitnble plug l2 is provided to close tle entrance il end to hold the refrigerant therein. Cerbon dioxide ges sublimed trom the solidiiied carbon dioxide within the refri erent container wili escape by the plug or through any conventional opening es shown et i3.

lit is Well known that carbon dioxide ges is quite difcult to maintain yWithin en enclosure or container unless particular eiorts ere mede to moire the container ges tight, and `unless the plug is very eccuretely ntted to the openin P, the carbon dioxide ges Wili escape thereiioin, thus obvieting the necessity for e. positive vent. However, il have shown e conventional vent through the plug itself. @he plug ll can be ci any suitable type either being threaded or held in piece by wedv'ing.

in one end of the container 6, prefereb y et the end opposite the opening il is en opening le to permit of eccess to the chamber 9, end has any suitable closure l5, either threaded or otherwise, covered by the outer cover 17 `which is mede in the form of e cup .and may be used for drinking purposes.

The straps 18 ere provided to hold the Vacuum section in collapsed position against tension of the springs 5. v

Fig. 3 is e regmentsry section, on an en- `of any suitable material and the springs 5" may be attached to these strips and the container 6 in any suitable manner.

The operation` of the device is simple and obvious, being as follows: l

The plug 12 is removed and the solid carbon dioxide in the desired quantities is placed within the container 7, the plug then being 15 replaced. -The liquid or material to be refrlgerated is placed within the container 6 through the opening 14. The air has previ-v ously been exhausted from the space 8 and the same hermetically sealed, thus providing' a vacuum around the longitudinal' Walls of the container 6, the springs 5 normally urginv the outer casing to extended position.

ElVhen it is desired to compact the unit, pressure may be applied against the springs, thus collapslng the outer casing and the same may be held in collapsed position by means of the straps 18.

Y At times it may be desirable to supply a larger amount of refrigerant than the ca acen one is travelling and needs to have a charge of refrigerant that will last an unusually long time, or it might be desirable to refrigerate the product to a lower temperature than is normally required or .even to freeze the same, in such case` the container 7 may be converted to a refrigerator -`chamber and the container 6 converted to a refrigerant container. l y. 40 From the above it will be seen that I have provided an etlicient, simple and compact unit e 1n which may be embodied the vacuum principle for supplying heat insulation and at the same time a simple and inexpensive structure in which may be utilized the unusual refrigerating qualities of solid carbon dioxide. I have also supplied a refrigeratory container in which neither the refrigerant nor the gas therefrom comes in contact with d0 the material to be refrigerated.

Fig. 4 is a slight modification disclosed without the outer vacuum providing casing which may or may not be placed thereon. In this modification the entrances to both the 55 refrigerant container and refrigerator chamber are in the Same end of the unit. This fornis particularly adaptable in the larger refrigeratory containers especially of the Water bottle type. The bottle 1b has the 0 opening 2b therein and the refrigerant container 3b locatedtherein, the entrance 4b of the' container 3b being closed preferably by screw threaded plug 5b and is shown as having therein the conventional vent 6b. ,This

construction is more applicable to the type ityx of the containery 7 this might come a out v w that requires to be charged either with a refrigerant or material7 to be refrigerated generall only once a day, it is especially adaptab e in lace of the ordinary large water bottle. Ilf it is desired to maintain a very low temperature within the container 1b, the same form of outer vacuum providing means, as shown in Figs. 1, 2 and 3 may be ap lied.

llVhile the forms I have disclosed are preferable, nevertheless any number of chan es or modifications might be made without eparting from the spirit or scope of the invention and I do not mean to be limited to the specific structures here shown.

Having thus described my invention, what .I claim as new and desire to secure by United States Letters Patent is:

1. In a device of the class described, the combination with an exterior collapsible container, of an interior bottle connected with the container, inverted U-shaped springs pivotally connected at one end to the bottle, metallic strips secured to thc inner sides of the container, and the other ends of the springs being connected to the metallic strips, to normally urge the collapsible container into open condition. v

2. In a device of the class described, the combination with an interior bottle, of an exterior collapsible container hermetically connected therewith and presenting a vacuum therein, springs, for'normally ur 'ng the collapsible container into 'open position, and straps secured to the said collapsible contain- I er and arranged for holding the collapsible container in colla sedv position. v

3. A device of t eI class described, comprising an interior bottle, an exterior collapsible `container hermetically connected therewith and' presenting a vacuum therein, a means for normally urging the collapsible container into open position, and a means arranged for holding the collapsible container in collapsed position.

4. A' device of the class described, comprising a container adapted for holding liquids and provided with a chamber arranged for holding a'refrigerant, this chamber being integral with and formed within the outer surface of the container, and a second contain.- er hermetically-sealed and presenting a vacuum therein, surrounding and attached to the said container, together with an exterior protective casin for said second container.

5. A device o the class described, comprising a container adapted for holding liquids -and provided with a chamber, arranged for holding a refrigerant, this chamber being formed within the outer surface of the con` tainer, and accessible thru the bottom of the container, said container being arranged for providin accessibility to the' interior there- 'of thru tie top, and a second container hermetically sealed and presenting a vacuum ,tliex'ein surrounding and nttaclfiedA to the sides o he container.

6. A container of the vacuum type comprising an inner refrigerant conta1ner,an outer container surroundin said inner refrigerant container and adapte to contain the material to be refrigerated, and a collapsible outer casing surrounding said outer container, said outer casing being arranged to maintain a vacuum around said outer container.

7. A container of the vacuum type comprising a refrigerant container and a refrigerated chamber, said refrigerantn container and said refrigerated chamber being made integral and an outer collapsible casin adapted to maintain a vacuum around sai integral structure.

ln testimony whereof I have amxed my signature.

JOSEPH WENSTEIN.
