Application August 28, 1948, SeralNo; 46,6789

12 Claim.` o l This invention relates to' containers' and in particular to one used for holding a nursing bottle: i

A particular object of the invention is to provide a container of the character referred to 'which controls the heat'or cold loss from a bottle the container at a certain time will be at the i proper temperature for feeding an infant at a specified time.

Further objects of the invention are to provide' means for mounting an inner tubular container in such suspended relation with an outer jacket that a single air space surrounds the sides and bottom of the container; to provide mounting means for the container so that in manufacture, the inner container and the outer jacket may each be made separately and completely to facilitate assembly; use fewer parts than heretofore found necessary in the making of similar devices; to keep the cost of the product at a minimum and produce a strong, durable, sanitary container that can be used repeatedly.

With these and other objects in View, the invention comprises certain constructions hereinafter described and then particularly pointed out in the claim and a preferred embodiment of my invention is illustrated in the accompanying drawing, in which:

Figure 1 is a view in perspective showing the outward appearance of the bottle receptacle,

Figure 2 is a vertical section through the container taken on the line 2-2 of Figure 1,

Figure 3 is a fragmentary vertical section taken at the periphery of the container and greatly enlarged to show the details of construction, and

Figure 4 is a view in section of a piece of a spacer disk used in suspending the inner tube or receptacle.

Referring to the drawing in detail, It indicates a bottle holder made from inner and outer tubular sections II and I2 respectively which will be hereinafter referred to as the container and the jacket. Both sections are made from a suitable insulating material such as cardboard,

2` asbestos or ber board and are tubuiarly shaped so that the container III positioned concentri` cally in the jacket |21 will be spaced from'the latter at its side and' bottomv to provide asingle dead airspace that'will serve as an insulatin medium. j

The lower end of the jacket I2' is closed' by a bottom disk I3 of metal or plastic whose edge is beaded as at I'4 to enfold the lower edge ofthe material to securely hold the bottom in place, and prevent air leakage. The lower end of the container I'I is likewise closed by a bottom di's'k 'I5 whose beaded edge I5Afseal`sl the bottom of the container to prevent the passage of air and also securely grips the material to provide a support for a bottle placed therein, as indicated in outline in Figure 2.

The upper end of the jacket I2 is provided with a circinate spacing disk II beaded as at I'I about its periphery for gripping attachment to the upper edge of the jacket material and shaped to provide an annular inwardly and downwardly directed flange I8. The inner diameter of the disk iiange I8 is less than the outer diameter of the container II and the lower edge of the tapered flange is slightly crimped as at 2G, to permit the ange to yield and grip the outside of the container so that, as the latter is forced downwardly through the disk, the bottom edge of the latter embeds itself in the material as shown in Figure 3.

The upper end of the container is covered by a guide band 2| beaded as at 22 over the upper edge of the container material and constituting a stop means. When the container .is forced down through the ring, the material of the container may yield, but when the lower edge of the band 2I passes the flange I8 the material no longer yields and the crimped edge 20 of the flange digs into the material to provide a locking means which prevents withdrawal or rising movement of the container out of the jacket. The band 2l and the flange I 8 coact to firmly x and hold the container axially of the jacket and the bead 22 supports the container in suspended relation to the disk I6 to provide a single insulating air chamber about the sides and bottom of the container so that a uniform insulating eiTect is obtained by the free circulation of air in the chamber. The spacer disk I6 acts as a closure for the upper part of the chamber and prevents leakage of air.

The holder is closed by a cover 24 whose tubular section 25, made of the same material as the container and jacket, extends down over the outside of the jacket with a snug sliding fit. The

cover is closed completely at one end by a crown disk 26 beaded as at 2l to grip and hold together the upper flared edge of a cup-shaped metal shell or cap 28 and the upper edge of the material. The side wall 29 of the cap abuts the inner surface of the portion 25 and serves as a reinforce for the upper end of the holder. The bottom 30 of the cap may be at as in Figure 2 or may be shaped to provide a well 3l at the center thereof as shown in Figure 3. This well increases the depth of the insulating chamber; serves as a guide in putting the cover on and also prevents excessive endwise movement of the bottle in the container.

The inner Walls of the container and jacket may be covered with foil or any material offering a slick surface that can be easily kept clean and sanitary and will allow the bottle to he easily slid into the container and withdrawn therefrom particularly when moist or damp.

My invention is not to be restricted to the precise details of construction shown since various changes and modications may be made therein Without departing from the scope of the invention or sacrificing the advantages derived from its use.

What I claim is:

A receptacle of the character described comprising concentrically spaced inner and outer tubular sections constituting an inner container and an outer jacket, respectively, bottom disks closing each section, a circinate spacing disk disposed in the upper end of the jacket and having a central opening, said disk having a peripheral 4 bead for gripping engagement over the upper edge of said jacket and a depending crimped flange bounding said opening, a relatively wide guide band tting into the upper open end of the container and having a bead for gripping engagement with the upper edge of said container, said band ccacting with said crimped flange for gripping the container and holding the saine in place concentrically of and spaced from said jacket and in spaced relation with the bottom disk of said jacket, a tubular section slidably litting over the upper end of the jacket, a cup-shaped cap closing one end of the tubular section to complete a cover for the jacket, and said cap being shaped to provide an inwardly extending well concentrically thereof and constituting a guide projecting into said band to provide a closure for the container, a crown disk fitted into the upper edge of said cap to provide with the cap a sealed air chamber and the cap being arranged to seat on said peripheral bead when the cover is in place. l l
