RECEPTACLE.

Application led April 4,

To all whom t may conce/m.'

Be it known that I, EUGENE A. ROBE, a citizen of the United States, residing at New Concord, in the county of Muskingum and State of Ohio, have invented certain new and useful Improvements in Receptacles, of which the following is a specification.

This invention appertains to certain improvements in shipping or storage receptacles generally, and more particularly to a type ofthe same adapted to maintain the contents thereof at an even temperature` either hot or cold, throughout the desired period of shipment or storage.

The principal object of the inventlon 1s to provide for a receptacle or container of the class set forth, and one of la novel, eiicient and substantial construction and arrangement, but which will be comparatively light in weight and inexpensive to manufacture.

Another object of the invention is to provide for a receptacle `or container as hereinbefore characterized, and one of a double wall construction, whereby to have a vacuum created within vthe space between the walls thereof, and wherein a means is provided to strengthen these walls to withstand the ordinary hard usage to which the receptacle or container may be subjected, and without injury thereto. u

With the foregoing and other obJects 1n view, the invention resides in the certain new and useful construction and arrangement, which will be hereinafter more fully described, set forth in the appended clalms, and illustrated in the accompanying drawin ,in which'zigure 1 is a vertical section through a preferred embodiment of the receptacle or container,

Fig. 2 is a bottom plan view 'of the lower end of the intermediate reinforcingshell of lthe device, and showing one form of valved closure for the vacuum space of the container or receptacle, and,

Fig. 3 is a similar view, but showing a 'modified form of closure for the vacuum space of the container or receptacle.

Referring to the drawings, 10 indicates an outer casing open at its top and having a closed bottom 11. The body`of the casing 10, at a point removed from its open end, is formed with an outwardly extending bead 12 which provides a seat for the edge of the .ange of a cover 13, which-is employed for closmg the open end of the casing 10. The

1922. Serial No. 549,557.

cover 13, as well as the casing 10, is provided with a lining 14, such as sheet asbestos or other suitable material.

Fitted within the casing 10 is an intermediate shell 15 having on its outer surface a spiral flange or web 16 spacing the same in position with respect to the inner lined wall of the casing.' The lower open end of this shell 15 is inwardly thickened to provide an inwardly tapered annulus 17, which has its tapered face threaded to receive therein a closure 18. This closure 18 is preferably of a concavo-convex formation and is formed to provide a nippled opening 19, which has its bore threaded to receive therein a screw reinforcing ribs 21 extend across the con cavity thereof in parallel relation one with respect to the other, theinner of said ribs being spaced to either side of the valve nipple 19. The upper open end of this shell 15 is inwardly curved as at 22, and this curved portion is inturned to provide an an` nu/lar flange 23, which is threaded to receive therein the threaded open end of an inner container or receptacle 24, and, when the latter is properly positioned, it will be securely supported with its walls spaced from the walls of the shell 15, and with the edge of its upper open end Hush in the plane of the upper open end of the shell. The open end of the container or receptacle 24 is closed by an inwardly'depressed friction cover 25 having an outturned Harige 26 snugly contacting the outerwall of the curved portion 22 of the shell body, when properly positioned. To support and strengthen the center ofthe cover 13, of the outer casing 10, the inwardly depressed wall of the container cover 25 is formed to provide a centrally and outwardly disposed vconical depression or projection 27, which has its apex termi" nating in the plane of the upper surface of the flanged portion 26, whereby the inner lined-surface of the closure 13 will bear directly thereon, when placed in position on the outer casing .10, so that a dead air space is formed in the depression of the cover 25 at the outer end of the container 24.

In assembling the device as thus constructed and arrangedy the container 24 will sov be secured in position within the shell 15 and the end closure 18 at the lower end o the latter, when a vacuum will be drawn in the space between the opposed walls of the container. and the shell, the drawing of 'the vacuum being affected through the plug valve 20 in the closure 18. The assem'bled container andshellwill now be inserted into the casing 10, when the channelway of the spiral flange or web 16 will be packed with asbestos, mineral wool or the like 28, the same lling the space between the shell 15 and the interior of the casing 10 flush with the upper open end of the latter, whereby toV be tightly packed when the casing cover 1? is placed in position. The interior of the container 24 is preferably lined with waxed paper or the like 29, so that the material to be placed within the same will not come in contact with the bare wall or walls thereof.

This shipping and storage container has been designed to greatly reduce the' weight and manufacturing cost of such devices, and the reinforcing means; i. e., the spiral flange 16 of the shell 15, the ribs 21, 21', of the bottom closure 18 of the latter, and the conical projection 27 of the upper closure 25 thereof; is deemed ample to afford suficient resistance and strength to the walls ofthe outer casing 10 to withstand any and all pressures brought to bear on the same during the ordinary hard usage yaccorded articles during shipment and without injury thereto.

In its preferred embodiment, the receptacle or container in its entirety will be made in cylindrical form, substantially as shown, and preferably of aluminum, although any other suitable metal may be employed for the purpose, the intermediate shell 15 being of cast metal andthe inner container 24 andthe outer casing 10 of sheet metal. The receptacle may be conveniently and economically used for the shipment or storage of any and all classes of perishable food stuffs, either solid 'or liquid, such as fish, meat, milk, oysters, ice cream and other frozen delicacies, or the like.

It will be understood that, while apreferred embodiment of the device has been described.

and illustrated herein in specific terms and details of construction and arrangement, various changes in and modifications of the same, such, for instance, as replacing the metal container closure, indicated by the portions 25, 26 and 27 (but not necessarily including 27 in shape), with one made from cork or vthe like, may be resorted to without departranged to provide spaces between its outer wall and the inner wall of said casing and its inner wall and the outer wall of said container, said member having an inner and outer open end, said container engaging with the outer end of said member for closing it, a removable closure for an inner end of said member, a spiral element interposed between the inner wall of said casing and the outer wall of said member to strengthen said walls against injury or collapse, a packing :filling the outer space between said casing and said member and within the channelway formed by said spiral element, and means whereby a vacuum may be drawn in the space between the inner wall of said member and the outer Wall of said container.
