CONTAINER 2 Sheets-Sheet 2 Filed Dec. 10, 1958 INVENTOR. C. 57'? IC KER 7 United States Patent 3,118,559 (IQNTAENER Henry C. Striclrer, 3L, Edgerton, Win, assignor, by inesne assignments, to Highway Trailer industries, inc Edgerton, Wis, a corporation of Delaware Filed Dec. lb, 195%, Eer. No. 779,442 4 Claims. (ill. 22--9) This invention relates to containers, and more particularly to containers which are often described as shipping or warehousemans containers.
Containers of the class to which this invention relates, are most commonly used for shipment of goods overseas, and as such are returned and re-usable for subsequent shipment. Such containers often are intended to enclose and keep in usable condition products which are serniperishable and often times such products as are adversely affected by moisture.
As a particular example of products which are shipped in containers of the class described, it may be noted that coffee beans are often handled in this manner, the beans being placed in bags and the bags in turn in metal containers which are usually of light metal such as aluminum or the like for the obvious reasons of weight saving purposes.
f /hen containers of metal are used, these being generally more easily reinforced and thus subject to more frequent handling with less damage, condensation ithin the container often develops by reason of the change in climate to which the containers are subjected in srdprnent from countries such as South America to the United States. Gbviously condensation promotes certain fun-gas growth which is damaging to the products and desirably necessarily eliminated as much as possible.
The present invention is, generally speaking, directed to the particular phase of containers which relates to the development of condensation therein and is intended to eliminate damage caused by such condensation, so as to provide suitable dry containers, irrespective of the varying climates through which the containers may pass before reaching their destination to have the goods therewitlin removed therefrom.
h the foregoing general understanding set forth it is a principal object of this invention to provide a container which is suitable for shipment of goods therein, which container will eliminate the damage caused by condensation, permitting circulation into the container and substantially excluding condensation from developing therein in such a manner as to damage goods enclosed thereby.
It is a still further object of this invention to provide a container in which a double skin so to speak is availed of :to provide for the entrance of air and the egress of moist air from within the container to thereby cause the condensation to drain to the exterior of the container and prevent the same from passing into the interior thereof in such a manner as would damage the contents.
An even more particular object of the invention is to provide a container in which the inner and outer walls are arranged in conjunction with the structural members of the container to comprise a series of cells arranged in such a manner as to permit air circulation through the cells to the interior of the container and permit likewise the condensation developing to pass downwardly through the cells and out to the outside of the container.
Yet another object of the invention is to pr vide a suitable ceiling arrangement within the container whereby the said ceiling is perforated in such a manner as to permit the moisture laden vapor to pass outwardly therethrough and if condensation takes place on the under side of the top or roof of the container said condensation in dripping downwardly will pass downwardly toward the "ice sides and into the cellular construction of the sides and hence downwardly and outwardly from the container.
Another important object of the invention, is to provide for what may be termed drainage and breather units arranged in the wall construction in such a manner as to receive condensation passing downwardly between the inner and outer walls and cause said condensation to be directed outwardly of the container entirely through suitable openings provided in the outer wall therefor.
A still further object of the invention is to provide a container in which the ceiling construction is perforated as set forth hereinbefore, the perforations having lip-s therearound extending upwardly from the upper side of the ceiling whereby moisture running down over the surface or" the upper side of the ceiling will be prevented from passing back into the perforations and more particularly be directed toward suitable drainage and breather units at the lower most portions of the container so as to be removed from the container by gravity.
Other and further objects of the invention will be understood rom a consideration of the specification appended hereto and shown in the drawings wherein:
FZGURE 1 is a perspective View of a container embodying the invention hereof, certain elements being broken away to more particularly illustrate the construction of the container.
FIGURE 2 is an end elevation in section of the container shown in FIGURE 1 likewise further illustrating further details of construction.
FEGURE 3 is a somewhat enlarged fragmentary sectional view showing the manner of connecting the ceiling with the roof joists.
FIGURE 4 is a fragmentary sectional view of one part of the connection of the ceiling and inner wall of the container.
5 is a somewhat enlarged fragmentary sectional view showing the relation of the drainage and breather units With the wall construction.
Pl -URE 6 is a perspective view showing a drainage and breather unit.
FIGURE 7 is a side view illustrating the said drainage and breather unit in somewhat enlarged detail.
Turning now to a consideration of the drawings, the container hereof which has been previously suggested is of the so-oalled warehousenrans type, is shown in FEGURE l in perspective as including th top 1, sides 2 and 3, the front side being designated 4. The rear side in this particular instance is formed by a pair of doors 5 and 6 which are suitably hingedly connected at 7 for example to the sides 2 and 3, said doors being swingable and perrnitting access to the interior of the container. As will be probably understood, the containers of this nature are of rather large size and facilitate the placement therein of quantities of foods such as coffee beans by hand trucks or other means, the containers being of such a size as to permit access by individuals as necessary. The doors 5 and 6 may be provided with any suitable latch means designated 8 and not otherwise shown in detail. The
door construction is largely identical to the side con- 1 struction and the construction of the side such as f. illustrates the similarity, although the side 3 wih be described in particular detail with reference to FIGURE 2 and subsequent figures.
The sides of the container are constructed of an outer skin such as 9 wMch in many containers and in this one as an example maybe of aluminum and thus a smooth member, constituting an aluminum wall extending from a lowermost position at a skid member 19 to a top rail 11.
The inner wall denoted 12 is as shown in the FIGURE 5 disclosure constructed of plywood for example indicated at 13 to which is secured as by bonding, a metallic sheath, in this instance preferably aluminum, denoted 14. The
interior of the entire container is therefore wooden as far as the sides are concerned at least that in so far as the portion which is exposed to view.
The aluminum sheath plywood combination 13 and 14, is in turn suitably fastened to vertically extending stakes denoted 15 which are likewise preferably of aluminum and of hat-shape in cross section or any other preferred shape as will be readily understood by those skilled in the art, the inner wall 12 being spaced from said stakes 15 by means of a wood strip such as indicated in FIGURE 4 at 16, the stakes being commonly secured as by riveting at 17 to the elements previously described including the wood strips 16 and the inner wall 12.
Extending transversely from the upper rail 11 are the roof joists 18 which roof joists support a sheet aluminum roof covering 19 thereon and at their central portion are provided with a ridge pole shown in enlarged detail in FIGURE 3 at 2%, the ridge pole being secured to the joists by means of the rivets such as 21.
The ridge pole 2% is in turn provided with a pair of grooves such as 22, which in turn support the inner edges of sheathed plywood sheets such as comprise the inner walls 12, the plywood sheet being indicated at 23 and the metallic sheath being denoted 24.
The ceiling is therefore arranged as shown in the F1"- URE 2 disclosure so that it slopes outwardly from the ridge pole to the outer edges and is supported by suitable short angle members denoted 25 in turn suitably riveted at 2d to the stakes 15 whereby the outer edges of the ceiling sheets are supported on the upper edges of the inner walls 12 additionally having the ribbons 28 afiixed thereto to provide greater bearing for the outer edges of the ceiling sheets.
The ceiling sheets of the ceiling itself are arranged so as to be perforated in a manner such as is indicated in detail in FIGURE 3, suitable openings in the ceiling being provided, about one per square foot, and consisting of a half inch hole for example denoted 3G in the wood 23 of the ceiling. The metallic sheath portion is extended to form a lip such as 31 around each hole, the opening therein being somewhat smaller than the opening 39 for purposes which will be subsequently set forth. All of the perforations in the ceiling are of this nature and are provided in this manner so that moisture laden air in passing from the interior of the container upwardly through the openings 36 will condense on the under side of the roof or top 19, subsequently drop off the roof, and run downwardly over the ceiling to the cells provided by the inner and outer walls previously described in combination with the stakes as indicated.
When the moisture reaches the cells, and passes downwardly therein, it will be collected at the bottom of each cell by a drainage and breather unit generally denoted 32, and more particularly shown in FIGURE 6 as comprising a generally rectilinear member which may be formed of wood or similar material having in its upper surface a generally V-shaped groove denoted 33. The apex of such V-shaped groove at 34- causes moisture to flow into suitable vertically extending openings 65' in the body of the breather unit 32 and thence downwardly to a slot which may likewise be V-shaped in cross section as indicated at 36 in FIGURE 5. The slot 36 is arranged as shown in FIGURE 6 so that the end sections 37 and 33 are somewhat higher than the central portion 39. Thus moisture passing through the vertically extending openings 35 will collect at the juncture of the sections at 39.
The breather units 32 now being described are located in the bottoms of the cells about as indicated in FIG- URE 1 with the portions of each of the slots 36 at 39 opposite an opening such as 49, which opening 49 is in the outer wall 9 of the container. Thereby when moisture collects in the groove 33 and passes downwardly through the openings 35, thence into the slot 36, it will in turn pass outwardly through the opening 40 md thus out of the container completely. The breather and drainage units 32 are located about as shown in FIGURE 2 and FIGURE 5 in relation to the container itself so that these units are below the floor 42 and thus just above the skid members 1% and thereby are in the lowest place possible with relation to the container as a whole.
The floor 4 2 may be prefenably a hard wood floor and supported on suitable joists such as 43 fastened in any preferred manner to the rest of the container so as to completely enclose same and provide added or necessary rigidity thereby.
It will of course be understood that a drainage and breather unit will be provided at the bottom of each of the cells or between the stakes 15' as the case may be, the doors 5 and 6 being similarly arranged to provide for drainage of moisture collecting therein.
The foregoing description of the novel container hereof, discloses the unique manner in which moisture is prevented from causing harm within the container, since condensation which may take place will take place between the walls and between ceiling and roof or top as the case may be and moisture developed thereby will pass downwardly and out of the container so as not to damage goods therewithin. The drainage and breather units are so arranged as to collect the moisture and the use of metallic sheaths and wooden inner walls is such as to prevent the moisture from damaging the walls and yet availing of the insulating protective qualities of the wood with which the same is associated.
