HEAT-INSULATING CONTAINER Specification of Letters Patent.
Continuation of application Serial No. 120,775, led September 18, 1918. This application filed Iarch 25,
1918. Serial No. 224,661.
To aZZ whomy t may concern:
. Be it known that I, LINZY HICKS, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Heat-Insulating Containers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will en able others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in heat insulating Wall material and containers made therefrom, and more particularly to the class of containers especially adapted for storage and transportation of substances requiring maintenance of substantial uniformity of temperature 'different from atmospheric temperature.
This application is a continuation of my application Serial No. 120,775, filed September 18, 1916.
The principal objects in view are simplicity and inexpensiveness of construction and efficiency in use; the provision of containers of paper or other fibrous material formed with dead air spaces in the wall thereof and constructed with the dead air spaces as a part of the Wall; and the provision of a wall structure possessing innumerable dead air cells inherent in its formation.-v l
With these and other detail objects in view as will in part hereinafter become apparent and in part be stated, the invention comprises certain novel constructions, combinations and arrangements of 'parts as subsequently specified and claimed.
In the accompanying -drawings,
Fi re L is a vertical central lsection taken longitudinally through a container embodyingT the features of the present invention.
ig. 2 is a top plan view ofthe parts seen m Fig. 1, parts being broken away and parts being seen in section a proximately on the planes l indicated by ine 2-2 of Fig. 3 is a detail, fragmentary view taken on the same plane as Fig; 1, and shown on a reatly enlar `scale.
ig. 4 is a etail, fra entary vertical section of a further emb ment of the instantially on the plane indicated by line 9--9 of Fig. 8.
The invention is particularly applicable to containers for the transportation and other handling of substances which must be retained at a temperature differing from that of the atmosphere, and the invention is also useful in the formation of wall structures .of general application.
The container may have any desired contour but is preferably cylindrical as shown in Fig. 2, since the cylindrical form enables the use of a continuous sheet of corrugated material rolled into spiral form, producing successive layers 1, 1. A sheet of asbestos or other appropriate heat insulating material 2 is disposed between two of the layers l at one place in the Wall, other portions of the Wall being constructed without the extra intervening sheet, and it is apparent, of course, that the sheet may be entirely omitted where its insulating properties are not required. The sheet of which the several layers 1 are formed is initially constructed the same as ordinary commercial corrugated paperpwith one sheet of corrugated paper backed by one sheet of smooth flat paper, the two sheets being caused to adhere by adhesive ap lied along the ridges of the corrugated s eet. ance of two sheets, for each layer 1. I
The several layers 1 are spaced apart for forming dead air spaces, 2 additional to the air spaces provided by the grooves of the corrugations, and, in order to insure the maintenance of the dead air Spaces 2', cords 3, 3 are arranged between the several layers 1, the said cords being of sufficiently hard material lto sustain the sheets 4of corrugated paper a ainst coming into intimate contact.
This resents the ap aras clearly seen in Figo* en the device is constructed as.
. thus interposed between the mate contact with the cords 3, the cords.
extend across the corrugations of the layers and break the corrugations down crosswise and thus seal not only the spaces 2 but also the lon itudinal grooves ot' the corrufgations. he corrugated layers are pre erably moist during the rolling operation to prevent cracking or breaking of thev corrugated cells when theyaife crushed by the cords 3. This cross crushing of the ridges of the-corrugations produces a cross groove which is filled with cord 3, but it is the material of the crushed-down ridge in each instance which blockades and divides them into longitudinal cells with sealed ends. B v the inner grooves is meant the grooves next to the fiat sheet toI which the corrugated sheet is adhered.
-The ends of the tubular body of the container are given an appropriate Ifinish by 'compressing or forcing the ends of vthe layers 1 toward eachfother to render the saine more compact and to produce a taper 4 at each end of the container. A cord 3 is arranged at the line of eac-h angle formed by the taper 4 departing from the straight line of the side of the container. The cords at these points are particularly desirable to prevent the layers of corrugated material from becoming forced into intimate contact throughout their area.
A cover sheet or strip of any ordinary inaterial, such as a strong tough sheet of paper l, is placed about the terminal portions i and over the compressed ends of the layers. The several layers 1 and the sheets 5 are glued together or otherwise caused to ad here for holding the parts in their given relations.. The cords 3- are also .preferablr saturated with some toi-in of adhesive,`suc i as glue, so las to effectively connect the se'vera layers 1 and seal the dead air s aces 2.
The container body is provide with a' bottom formed of disks 6, 6, of corrugated materialV similar to the layers 1, the assembled mass of disks being covered by a sheet of paper 7, or other appropriate material, adhering to the edges of the disks and to the exposed faces of the terminal disks. Asbestos o1- other similar heat insulating material 8 is disposed between two parts ot the bottom, and the entire bottom is retained inposition in the lower end of the container body by glue or other similar adhesive.

terial and being provided with insulating material 10. The plug or closure is propo.-4 tioned to ittightly within the u per end oi the container body and to extent prefcrabl within the container for the greater portion of the length ot' the tapered portion l. flexible grip or handle 1l is embedded williin and fixed tothe plug for facilitating manual removal. The plug may be tapered downwardly when the interior of the crimped or'cruslied portion -l is flared so as to insure a close, tight joint between thev plirg and the container.
ie interior ot tlie`container is prefer-- ablyfinished with a sheet of parafiin paper or like material 12 for rendering the con tainer impervious to moisturel so that food or liquid substances may be deposited directly in the container and stored or transported therein. In the instance of use ot' the container for the preservation. yof icecream, the can in which the cream is frozen may be set directly in the container if pre- ()f course, the container is useful for storage and transportation 'of any products whose preservation or preparation rcquires the maintenance of a temperature different from atmospheric temperature.
It is obvious, of course, that the layers l may be distinct cylinders or parts of a continuous spiral where tlhe container is a cylinder, and will be. otherwise appropriately shaped where the shape of the container is different from that of a cylinder. It will also be obvious that various means may be employed for protecting the container against injury during shi nient, such protecting means being especial y desirable, for-containers of large dimensions.
In Fig. 4 is illustrated, diagrammatically. a container body provided with a protecting guard for the bottoni. This guard consists of a band of metal 13 fixed to a block oi' wood or other appropriate substance 14. the band being designed to receive the lower end of a container .body15 and to sufficiently tightly engage the same to retain the block 14 in position as a false bottom designed to receive shocks and ars during the course oi liandlin the container and to prevent injuryto the ottoni plug or closure 16 of the container.
In Fig. 6 there is illustrated a modified form of the invention wherein the tapering end 17 ofthe container is compressed or crimped suiiiciently to collapse the corrugations 18 beyond the cords 3. This construction eectually seals the outer ends of the cells of the layers, and they may be held together in crushed position by the strip 5 secured in place by an adhesive or the like.
Utl
` corrugated surfaces. Adead air spaces are provided between the Another modification is shown in Fig. 7 wherein the tapering portion 19 of the container body is crushed or crimped to break down the corrugations 20, and the ends of the layers are held together by `an adhesive with the strip 5 eliminated. The adhesive here used is of cementitious matter having a substantial body so as to fill the interstices at the end of the container, as indicated at 20. The cement when set and hard adds to the ri 'dity of the end of the body.
' In Fig. 8 a urther modification of the invention is shown, wherein the layers 21, corresponding toA the layers 1 of Fig. 1, are
. arranged alternately'back to back and face to face. In other-words, one layer 21 has itsI smooth surface presented toward the smooth surface of an adjacent layer 21 and has its corrugated surface presented toward the corrugated surface of another adjacent layer. The cords 3 are employed in the same manner and for the same purpose as in the structure above described, but it is obvious that where the cord ap ears between two ad jacent corrugated sur aces it produces the cross groove or crushed-down portion in both corrugated surfaces, and where the cord ap pears between two smooth surfaces it forms a cross groove by denting in the smooth sheets and crushing the corrugations in the rea-r of such sheets. The corrugations 22 are thus cross grooved and the longitudinal dead air spaces sealed between the In addition. tov this,
smooth surfaces spaced by the interposed cord 3. In this form of the invention, the tapering end 23 of the container body may be formed by compressing the ends of the layers together suiiciently to bring the smooth faces of the layers 21 into surface contact and to bring the ridges of corrugations 22 into contact. The air spaces within the corrugations 21 between the cords 3 and the extremities of the container body are sealed by the strip 5 held in place by an adhesive or the like.
Of course, the container may be built up of any combination of the various above-disclosed forms for sealing the spaces or cells within the wall of the container and providing a plurality of dead air areas to resist the passage of heat units through the walls in either direction.
It should be noted that the range of materials of whichV the insulating container may be formed is very wide and may include almost any form of fibrous substance, such as above described, and it will be, of course. further apparent that the invention will in no sense be departed from by the employment of fanciful finish or the addition of any appropriate metallic or other receptacle in which the insulating container may be placed for protection, and that various ad- 2.
