I BY z% 444 im ATTQQMEYi Patented Jan. 22, 1946' UNITED STATES PATENT OFFICE REFBIGERATING CONTAINER Charles EJiadsell, Los Angeics, Calif.

' Application January 18, 1944, Serial No. 518,'i07 1 Claim. (01. 62-1) This invention relates to improvements in refrigerating containers. An object of the invention is to provide a container adapted to receive and contain a plurality of articles that are to be kept or' maintained in a cooled or refrigerated condition, such as for example bottled drinlm, wherein the container is provided with means for maintaining in position therein one or more partitions. The partitions employed are removably positioned in the container and are hollow containing a refrigeratable medium. In the preferred form of construction the walls of the partitions may be formed of flexible' material although this. is not essential. In this manner, the partitions can be removed from the container and greatly cooled or even frozen, and when in this condition they may be inserted in the container to divide the container into a plurality of compartments each of which may receive the articles or bottled drinks that are to be cooled. The partitions thus serve a double function for maintaining the articles in proper position in the container and also cooling them with a minimum loss of refrigeration inasmuch as the cooling partitions are in close proximity to the articles that are to be cooled. As the parti- ;tions eventually absorb heat and consequently ever, during the warming process of the partitions there is no melting of the refrigerant and consequently, there is'no objectionable liquid or gas released in the container.

Another object of the invention is to provide a refrigerating container wherein a wall thereof, such as the cover, may have a recess formed therein adapted to receive and hold a refrigerating device which, as it absorbs heat will neither release objectionable liquid or gas.

With the foregoing and other objects in view, which will be made'manifest in the following detailed description and specifically pointed out in the appended claim, reference is had to the accompanying drawing for an illustrative embodiment of the invention, wherein:

in similar reference characters designate similar parts throughout, the improved refrigerating container consists of a suitable box-like structure III which may bein the nature of a bottle carton. Any suitable form of container structure. maybe used and the walls thereof may or may not be formed of a heat insulating material. In opposite walls of the container there are formed redium l6. The refrigerating medium may be any type of brine usually employed for refrigerating purposes. It may be any liquid susceptible of being greatly cooled. The walls l4 and I5 of thepartitions are'preferably formed of flexible material, such as for example heavy pliofilm or any Figure 1 is a longitudinal vertical section.

through one form of refrigerating container embodying the present invention;

Fig; 2 is a horizontal section taken substanone of the synthetic plastic compounds which will not become brittle under the temperature conditions to which the partitions may be subjected. It is not essential in all instances that the walls of the partitions be formed of flexible tions may then be inserted in the grooves ii and the articles to be refrigerated, such as for example, bottled drinks B may be positioned in the compartments l3. The partitions as long as they are still serve to maintain the bottles in proper positions in the container. At the same time as they are highly cooled and are in close proximity to the surfaces of the bottles they will serve to emciently cool the bottles and their contents. As heat is absorbed by the partitions warming up the refrigerant l6 therein no liquid or gas is released from the partitions which might be obiectionable. When the partitions are warmed sufficiently so that they no longer adequately cool the bottles and their contents, the partitions can be removed from the container and re-cooled or refrigerated and thereafter reinserted in the container.

i! and will descend over the contents in the container. In this construction it will also be noted that as the cooling device warms up there is no objectionable release of liquid or gas.

From the above-described construction it will be appreciated that an improved refrigerating container is provided wherein partitions in the container constitute the cooling medium by enahling eiiicient cooling of the articles placed in be cooled by the cooling device mounted in recess the container and avoiding the objections of releasing liquid or gas on cooling.

Various changes may be made in the details of construction without departing from the spirit and scope of the invention as defined by the appended claim, wherein I claim:

A refrigerating container having grooves in I opposed walls thereof, partitions having their ends receivable in said grooves and dividing the container into compartments, each partition being in the form of a flexible impervious container containing a liquid adapted to be frozen, whereby when the liquid is frozen the partitions will be still and may be positioned in their grooves in the containers as still partitions and serve to cool the compartments formed thereby, and upon melting the liquid will be entirely retained within the partitions forming containers.
