. the interstices or pores of such libre board or 15 linings,` particularly the exposed layers. Ingeneral, such compositions have the inherent weakness in that they tend to introduce foreign chemicals or ingredients into the product carried in the container either through reaction with the 20 material or through separation from the layer pores or surfaces to which they have beenapplied, with resulting contamination of the products.

It is an ,object of this invention to provide for an oil and water-proof container of the spiral' wound laminated wall formation, through the application of a lining of Cellophane, in conjunction with the fibre o'r chip board layers, and serving'; to provide an oil, grease and water-proof sealing medium for the container, the lining and the respective bre Aor chip-board layers being successively and concentrically spirally wound and adhesively united at their adjacent faces.

Specifically, it is an object of this invention to provide a container formed of laminated fibre board, and having its inner lining of Cellophane wound so as to provide a butt-jointrelationship of its edges, and with an additional layer of Cellophane co-extensive with the butt-joint of the inner Cellophane layer, the respective inner and intermediate Cellophane layers being united to one another at their co-extensive surfaces andl to the fibre board layer with adhesives. v Still further, it is an object of this invention to provide, in conjunction with the Cellophane inner lining aforesaid, a layer or lining of-Cellophane intermediate of the several laminations of bre board forming the body of the container, said Figure 2 is an elevation in cross-section of a.v j

modiiied form of our invention.

Figure 3is an elevation in cross-section showing a container formation incorporatingl our invention.

Figure 4 is a perspective view of a container incorporating our invention.

Referring to the reference characters in thev drawing, numeral lll-discloses the laminated wall formationlfor containers adapted to carry uids or solids of oily or-greasy composition; said wall formation beingl produced by the spiral 'winding of material along the mandrel forming lengths' o'f a"cylin'drical construction, which may be cut into.sections of desired length. The material applied is generally in'the form of rolls having a width less than that of the desired sections to form the body of the container'.`

1- AS shown in Figure 1, the laminatedwall built up by spiral winding comprises of an inner layer vor lining A of substantially water and oil-proof Cellophane,'coated on its rear'face with a'n adhesive G, the spirallylwound sections A-I, A-2

. and A-3, being wound about a mandrel so thatr the adjacent edges m-'I and m-Z of the respective sections are in abutting relationship.

The next adjacent layer B is formed of Water and oil-proof Cellophane coated on its faces with an adhesive G, the respective sectionsB-I,

B-2,`etc., forming the spiral winding, being spaced from one another and being disposed so as to be coextenslve with the edges m-I and m-Z of the sections A-|, A-2 and A--3 of the inner Cellophane layer A, thereby to back up and form `a. seal at the butt-joint between such sections.

A series of layers, C, D, E and F, formed of libre or chip board are next formed by applying in spiral winding respectively, sections C-i to C3, D-I to'D--3 and E-l to E- 3, each of such sections having glue G on their inner faces, lthe spiral windingybeing arranged so that the butt-joints of the sections of. each layer are spaced with respect to the butt-joints of the section of the next adjacent layer. The number of layers of bre orchip board may be varied, dependent upon the thickness and rigidity of the laminated wall desired.

' The exposed surface O of the outer layer F may be coated with a composition for sealing the pores thereof as, for example, varnish or thelike, although in general the label or paper cover which may be applied to such outer layer with an adhe- `sive may be vof such impervious stock as to-eliminatethe necessity for coating such outer layer,

or a layer of asphalt may be applied on the inner face of the layer-E to act as an adhesive and waterproofing medium for the wall structure.

In the modification' shown in Figure 2., the 1aminated wall construction involved essentially is the same as that shown in Figure 1, except that there is disposed between layers D and E a layer H formed of water-proof Cellophane, the sections H-|, H-Z and H-3 preferably being lap wound at the edges 1v1-I and n-2 thereof. It is Vpointed out that layer E has no glue coating on its inner surface, as differentiated from the rest of the nbre or chip board layers, so that the Cellophane layer H has no adhesive between it and the adjoining faces of layers D and E, such Cellophane layer being maintained in position only by the pressure of the winding and the surfaces of the nbre or chip board layers contacting therewith.

Itis pointed out that the inner layer A Cellophane, the butt-joints of which are sealed by layer B, serves as a grease-and oil-proof inner Wall formation to prevent seepageoutwardly through the nbre or chip board walls, while the layer'H of Cellophane serves as a water-resistant formation serving to prevent the penetration of water or moisture from the exterior towards the interior of the container.

As shown in Figure 3, the end of a section formed by transversely cut elongated wall formation to provide a cylinder fora container and having a raw edge, by virtue of the cutting operation, is coated or sealed with an adhesive L of the nature of relatively water-free latex or vegetable matter, so that liquid or moisture may not penetrate downwardly through the layer formation of the wall, while at the same time providing means forv causing cover K, which ,is crimped thereon, to be rigidly adhered thereto.

It is obvious that various changes and modifications may be made to the details of construction without departing from the-general spirit of the invention as set forth in the appended claims.
