2 Claims.

The present invention relates to new and useful improvements in refrigerating devices and more particularly to a refrigerant holding attachment for use in cartons or other shipping containers to cool or preserve the contents thereof.

An important object of the invention is to provide a refrigerant holding attachment which may be easily and quickly placed in a shipping carton to support a cake of carbon dioxide, commercially known as Dry Ice; in a position for cooling the contents of the carton.

A further object is to provide an attachment of this character which may be attached to the lid of the carton to support the refrigerant in close proximity to bottles of beverages or other bottles or containers therein, whereby the contents may be kept cool for long periods.

Another object is to provide a refrigerant holder of this character of simple and practica1 construction, which is efficient and reliable in use, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a perspective view of the refrigerant holding attachment;

Figure 2 is a vertical sectional view of a carton showing the attachment supported under the lid thereof. and

Figure 3 is a plan view of the blank from which the attachment is formed.

Referring now to the drawing in detail, wherein for the purpose of illustration we have disclosed a preferred embodiment of our invention. the numeral 5 designates the refrigerant holder generally and which is constructed from a blank 6 of suitable sheet material of rectangular shape having chambers I formed at each end and projecting from one surface of the material.

The central or body portion of the blank comprises an attaching plate 8 at each end of which the chambers l are preferably formed by cutting or stamping the material adjacent each end along lines 9 and I0 parallel to the side edges of the lank to form a central tongue I I between a pair of side strips or legs I2 which are bent at right angles to the plane of the attaching plate 8 and the material outwardly from tongue II is then bent in the shape of a rectangular chamber I with the end portion I3 of the blank extending inwardly and looked under the tongue I I.

The ends I4 of the chambers are open and openings I5 and I6 are also formed in the sides and bottom of the chambers to expose the surrounding air to the cooling effect of cakes of carbon dioxide I! placed in the chambers.

The device is placed in a carton I8 by attaching the attaching plate 8 to the underside of the lid I9 of the carton by staples or other fasteners 28 to support the chambers 1 between the necks of rows of bottles 2| in the carton to thus cool the contents of the bottles.

In view of the foregoing description taken in conjunction with the accompanying drawing it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary- It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is: v

A refrigerating attachment for containers comprising an attaching plate, and a perforated chamber integrally formed at an edge portion of the plate and adapted for holding a refrigerant, said chamber having a pair of opposed walls, one of said walls being united with the plate and projecting downwardly therefrom and the other of said walls being united with the first wall at the lower portion of the latter, and said second named wall having an inwardly projecting upper free edge forming a top for the chamber, and a tongue integrally formed with the plate and overlying the top to hold the top of the chamber closed.

2. A refrigerating attachment for containers comprising an attaching plate, and a chamber at least at one end of the plate adapted for holding 4 REFERENCES CITED The following references are of record in the file of this patent:
