ATTORNEYS United States A Patent 2,998,129 REUSABLE TRANSPORTATION ICONTAINER Robert Q. Bekins, P.0. Box '2267, Tulsa, Okla. Filed Mar. 20, 1959, Ser. No. 800,806 6 Claims. (Cl. 20G- 46) This invention relates to a shipping container for articles of mixed sizes and shapes.

More particularly, the shipping container of this invention is intended for packing fragile articles, such as dishes, glassware, bric-a-brac, small statuary and innumerable other articles of a similar nature, found about the average household. l

. During the past two decades there has been a large increase in the long distance movement of` households and during that same time, there have been substantial increases in the cost of labor employed in the packing and handling of household goods. Because no two households present the same problems of packing and moving, a substantial amount of individual attention must be given to each job. Since the articles pass through several hands during packing, transportation and unpacking, it is sometimes difficult to iix the responsibility for damage resulting from a household move.

The apparatus of this invention is designed to provide a uniform and standardized method of packing, adaptable to substantially all types of fragile articles of household use. Itis adapted to require a minimum amount of packing labor while providing adequate safeguards for the articles packed. Heretofore, it has been usually necessary to employ time-consuming wrapping methods and dust-- creating packing materials. Such methods and materials frequently caused the loss of some articles in the packing material and made it necessary for the housewife to Wash each article after unpacking.

The present invention provides clean, dust-free packing material and utilizes it in such manner that wrapping is eliminated, thus avoiding loss of small articles in the packing material as well as the labor of wrapping and unwrapping the articles packed.

Although the packing apparatus of this invention is somewhat more costly than some of the previously used materials, it is capable of repeated reuse so that the actual cost per move is materially less expensive.

This invention is to be distinguished from various shipping packages specically designed to handle a plurality of articles of uniform size and shape. It is usually possible to design specific packages to handle odd shaped articles, even those presenting special problems, when many such articles are to be shipped, since the cost and effort are distributed over many packages. This invention proposes to deal with an unpredictably wide variety of articles, where no two shipments are the same.

For a fuller understanding of my invention, reference should be made to the accompanying drawing, wherein- FIGURE l is a cross-section, in elevation,of a shipping container, packed with a variety of articles;

'. .In the drawings, it will be seen that the numeral 10 represents generally the outer casing of a shipping container. At the present time, the industry has largely standardized upon a rectangular box of heavy corrugated board, 18" square and 30 deep. The subject matter a'tented Aug. 29, 1.9 61

"ice

of this invention is designed for use with this standard shipping container, although it will be apparent from a description as it proceeds, that the technique is equally applicable to other standardized sizes of shipping containers. Since it is important that the various like elements of the system shall be completely interchangeable, the advantages of standard sizes will be immediately apparent. y

It will also be apparent that thesidewalls 12 of the container 10 shall be parallel to provide the container 10 with uniform cross-section from top to bottom. A series of trays, indicated by reference numerals 14 to 20 inclusive, are employed; for convenience, the reference numeral 14 will be employed to designate these trays as a class, except where the description is specifically applicable to the single type.

The trays 14 are constructed of heavy corrugated board of the same general type as that from which container 10 is formed. Thewalls 22 of the trays are formed preferably, by turning up the edges of the body of the sheet of board from which the tray is formed. Although not speciiically shown in the drawings, it is desirable that the lapping tabs, where thesidewalls 22 are joined at the corners, shall be formed on the inward side of the tray 14. Similarly, if twoadjacent sidewalls 12 of the container 10 be joined by a lapped seam, the lapped portion should be on the outside of the container 10. Thus', the facing portions ofwalls 12 and 22 are substantially unobstructed by any irregularity that might otherwise impede the movement of the trays, vertically within the container 10. In order to minimize any needless movement of the contents of the container, in sidewise manner, it is preferred to make the external dimensions of the trays 14 just sufficiently smaller than the internal dimensions of the container 10, so that they will freely slide up and down in the container 10, without unnecessary play. To facilitate lifting the trays up out of the container, one or more hand holes 2S may be pro.- vided, for lifting the tray out of the shipping container.

At least the floor of each tray 14 is lined with alayer 26 of resilient foamed padding. There is a considerable choice of such materials presently available, such as foam rubber, polyurethane and polyester foams. The foam material employed must be characterized by a high degree of recovery after prolonged indentation. An especially convenient source of material for this purpose is had in the commonly Aavailable materials for rug padding since these are intended to resist wear and, at the same time, are available in thin sheet form, well suited for the lining purpose intended.

For packing plates 3i), a deep tray 18 may be used,

- stacking the plates on edge as shown in FIGURE 1, separated by resilient paperboard (not shown) of the type widely used for this purpose. Small amounts of remaining space may be lled in with one or more layers of corrugated board. Parallel stacks of plates may be sep. arated one from the other by means of partitioningdividers 32, extending from oneside 22 to the opposite side and extending substantially as high thereof. Toll out any space left by a row ofsmaller plates 34, a quantity ofcrumpled tissue 36 is added at the top of'tray 18; The tray 18 is covered by horizontally extendingpartition cover 38 formed of one or more sheets 'of heavy corrugated board.

A quantity of glassware 40, of generally uniform height, may be arranged in a shallow tr-ay 14, as sholwn in FIGURE l. Minor irregularities in height will be taken up by theresilient lining 24. A single short piece of glassware may be given increased effective height by a small piece of crumpled tissue. The glassware 40 is held in place by partition member orfollower 42 having afoam surface 44 in contact with the glassware.

A large article having substantially parallel top and bottom surfaces, such -as punch bowl 46 may be placed in one of the shallow trays and held in place by the cushioned partition orfollower 42.

A group of trays, when placed in the container Should ll the container slightly above the edges of thesidewalls 12 so that when telescopic Vcover 58 is applied to the container with its deep dependingrim 52, the various horizontally extending layers of cushioning material and 44 Will be compressed to rmly hold the packed articles in position. tlf necessary, a ller piece 48 of any suitable configuration may be used to distribute the pres- Sure with substantial uniformity from one tray to the next. The telescopic cover is held in compressed condition on the shipping container by any suitable strappingmaterial 54 such as adhesive tape, steel band strapping, or its equivalent.

As shown in FIGURE 2, thedeep trays 20 not vonly have -cushion material 24 on the floor thereof butadditional cushion material 26 upon the sides and thevertical partition members 56 havecushion material 58 on one or both sides thereof. This affords additional protection to larger articles of more irregular shape.Article 60, which does not extend upwardly suiciently to be held directly by the horizontally extending member above it, :is held against movement by a quantity of crumpledtissue 36.

It will be seen that the primary force holding each of the various articles against both sidewise as well as vertical movement, is the compressive force applied to the articles since, when compressed, the foam does not permit sidewise movement of the article bearing against it. Where tissue is employed, it is not used for wrapping but merely to provide a snug t. Thus, the packer does not need to handle and manipulate the article to be packed, as he would if he were wrapping it. A single movement of the hand and arm lifts the tissue, crumples it and pushes it down against the article to be held in position. Similarly, when unpacking, it is only necessary to lift the tissue out and discard it.

It will also be observed that the trays and partitions are essentially dust-free, thus preventing soiling of the articles packed. lIf desired, the padding material may be treated with an antiseptic germicide or a padding material may be selected that has inherent germicidal properties, as a result of its method of manufacture. Thetissue 36 similarly is inherently free of tendency to soil the articles packed. If, after reuse, the padding of any of the trays 14, appears to have accumulated soil, a single sheet of tissue may be laid, uncrumpled, upon the tray before placing articles upon it.

Some of the most diflicult household articles to pack are smallceramic gurines 62 and other yanalogous articles of irregular configuration. These may be eiectively handled in the present invention by placing them in shallow -trays 16 provided with bothiloor cushioning 24 andwall cushioning 26. The articles are placed usually with the attest portion downwards in the tray. Generous quantities of crumpledtissue 36 are placed throughout the tray to prevent sidewise movement of the articles, with sufcient amounts of the tissue extending above the rim of thewalls 22 of the tray. When a cushioningmember 42 is placed upon thetray 16, the downward pressure lthereon will compress thetissue 36 to prevent any movement of thearticles 62 during shipment. Here again, it is to be pointed out that the basic rule has again been followed that no wrapping has been taken place. The packing material has all been positioned by vertical movement and it can be removed in the same manner. Adherence to this principle is effective in saving labor, both in packing and unpacking; it minimizes the danger of loss of yany of the -articles in the packing material and it is effective in transporting the articles in a.

4 clean and sanitary manner, free of soilage from the packaging material.

The various elements of packing material are freely interchangeable, for versatility; and of sturdy construction, for protection of the articles shipped and for economy of reuse. A comparatively small number of types of packing material are capable of being combined in a Wide number of arrangements, enabling the handling of articles of almost any configuration.

The nature of the invention is such that this specification enumerates only a few of the many possible ways in which the elements of the invention can be combined according to the problems confronting the packer and accordingly, it is to be understood that the foregoing speciiication is presented for illustrative purposes and is in nowise limitative.
