United States Patent 3,106,327 FIBER CONTAINERS Clarence 0. Kari, Danvers, Mass assignor, by mesne assignments, to United Shoe Machinery Corporation, Boston, Mass a corporation of New Jersey Filed Feb..25, 1958, Ser. No. 717,468
7 Claims. (Q1. 2 29-4.5)
This invention relates in general to container structures and is more particularly addressed to inexpensive fiber containers, incorporating lapped seam COIlSlZIllCtlOIl,
'This outstanding problem is greatly aggravatedin lapped seam container or can bodies fabricated from paper, cardboard, chip board, and similar natural and synthetic available commercial fibrous materials, particularly adjacent the interior raw cut edge of the lapped seam of the container body, which edge acts to produce a wicking action for the liquid phases of the container contents.
It is also recognized that fibrous container bodies, as
a result of their inherent pervious or porous nature and interiorly exposed raw cut marginal edge adjacent a lapped seam joint in their construction, present a problem of deterioration and/or corrosive attack by many products. packaged therein, even in the dry state..
The present invention has as one of its objects the pro vision of a fiber container capable of preventing moisture seepage and/ or deterioration from within the same.
Another object of the invention isto provide a flexible fiber container body incorporating a liquid impervious lapped seam in its construction.
A further object of the invention is to provide a fiber container body having a continuous impervious and/or corrosion resistant layer or lamina on the exterior and interior surfaces of a fibrous blank from which'the container body has been fabricated. 1
Numerous other objects and advantages will be appreciated and understood from consideration of the following description, taken in conjunction with the accompanying drawing illustrating a preferred embodiment of the invention, in which: i
FIG. 1 is an edge view of a blank from which the container body is preferably fabricated;
FIG. 2 shows the body blank of FIG. 1 undergoing transformation in the formation of a container body;
FIG. 3 represents a transformed double-ply arrangement and disposition of the body blank of FIGS. 1 and 2;
FIG. 4 illustrates a fragmentary end view of a container body incorporating 'a lapped seam and fabricated from the double-ply blank of FIG. 3-; and
FIG. 5 is a partial elevational view of a container body, with a section adjacentan end cover member secured thereto, broken away. i v
A typical container body fabricated in accordance with the invention is formed from a single blank 10 of fibrous material provided on at least one major planar: surface with a layer or lamina 11 suitably attached thereto. The blank 10 maybe selected from a broad range of cellulose fibrous paper base materials, such as pulp board, cardboard,'chip board, kraft paper and similar available commercial paper stock, as Well as from synthetic fibrous stocks manufactured from Dacron, nylon, and/or mixphane, polyethylene, and the like.

. 2 tures thereof, and similar synthetic materials, any one or all of which, because of their inherent porous or pervious nature, can give rise to a problem of moisture leakage and/ or deterioration from attack by wet or dry products packaged in direct contact therewith.
The lamina or layer 11, on the other hand, is selected from a moisture-impervious and/or corrosion resistant material, such as metallic foils, or any one of the commercially available organic film materials, such as cello- The layer 11 will obviously be selected as the most efficient and desirable material for direct contact with the product or products to be packed, as well as being impervious and resistant to attack by the products in contact therewith.
The layer 11 must also be applied in the form of a continuous, unbroken layer over the entire surface area of at least one major planar surface of the base stock or blank 1t), and be adhesively or otherwise attached thereto. Any suitable commercially available adhesive exhibiting non-brittle setting properties, is preferably employed for this purpose, although the lamina 11 maybe selected with inherent heat-sealing properties permitting direct heat-sealed attachment to the blank 10.
Having selected the fibrous stock or blank 10, and liquid-impervious lamina 11 compatible with the product to be packaged, the laminated blank 1011 is folded double-ply on itself to provide the composite blank of FIG. 3., In this operation, the fibrous material 10- may be scored at 12 to a depth less than its gauge thickness to aid the folding or'doubling operation, and any suitable commercial adhesive or cement, that is non-brittle on setting, should be employed between the superimposed surfaces of the folded 'blank to insure the unitary double-ply blank of FIG. 3. V
In FIG. 4, a fragmentary end plan view of a lapped seam cylindrical container body fabricated from the double-ply blank of FIG. 3, is illustrated. It will be observed that the fibrous material or blank 10, from which the cylindrical container body has been formed, is exposed on three of its edges, termed cut or raw edges, whereas the folded or fourth edge of the blank is completely encased by the continuous unbroken impervious layer or lamina 11. It is also to be observed that the folded and lamina-encased edge is disposed on the interior of the container body at the lapped seam incorporated in its construction.
Any number of commercially available cements or adhesives may be employed to complete and secure the lapped seam of the container body, a heat-meltable or thermoplastic adhesive being preferred where the layer 11 is selected in the form of an impervious metallic foil. On the other hand, an impervious organic cellophane or polyethylene lamina 11 may be directly heat-sealed on the blank 10, as well as in the area of the lapped seam joint between such organic laminae. It is sufficient to state that the adhesive employed in the lapped seam contacting surfaces should be impervious and leak-proof in terms of the contents of the container body.
Fiber or metal end closures of covers 14 are employed .to complete the container of FIG. 5. In the event fiber covers are used, such elements would preferably be made, asby forming dies, from material in the form of the double-ply blank of FIG. 3, which would insure presence of the protective layer or lamina 11. disposed inwardly towards the contents of the container. Otherwise a metal cover or end closure 14 has been shown in FIG. 5 in clamping engagement with the peripheral wallof the otherwise open end of a cylindrical lapped seam container body constructed in accordance with the invention, as above described. The metal cover would normally be selected in the same metal employed for the metallic foil lamina 11.
The end closure 14, may, if desired, be adhesively treated, particularly on the interior surfaces defining the inverted channel-shaped marginal flange in direct surface engagement with the cut edge forming the peripheral end walls of the container body.
The exterior surface of the container body is usually printed or otherwise decorated as to the source and contents of the completed sealed container. In this connection, the exposed layer or lamina 11 would normally be printed over approximately half the length of the blank shown in FIG. 1 in a flat condition, the subsequent doubling of the blank to provide the double-ply laminate of FIG. 3 insuring an externally printed container body and finished container in accordance with FIGS. 4 and 5.
A specific example of a container made in accordance with the invention employed a single sheet 10 of 90 pound kraft paper stock coextensively and adhesively bound to a layer of aluminum foil of .00035" gauge thickness over one entire major surface area of the blank 10. The exposed foil layer or lamina 11 of the laminate thus produced was surface-printed and decorated over substantially half its area in its fiat condition, as viewed in FIG. 1, thereafter adhesively coated on its major planar fibrous surface, folded double on itself to provide the unitary double-ply blank of FIG. 3, and then transformed, as by progressively wrapping the same around a horn or mandrel, to form a tubular container body, such as illustrated in FIG. 4, and the completed container of FIG. 5.
It will be manifest that minor changes may be made in the container structures of the invention, without departing from the intended spirit and scope thereof, as defined in the appended claims.
