This invention relates to a functionally and structurally improved container, and in its more specific aspects aims to providean article of this nature which will be of particular value for use in 5 .connection with the storage and shipment of liq=-' uids such as oil, although it may obviously be employed to advantage in other associations. It is an object of the invention to furnish a receptacle of this type which may be manufactured from paper or fiber so that the weight and bulk of the receptacle will be minimized. The inventionadditionally contemplates a construction such that, although paper and similar materials maybe employed, this will be done without any effective sacrifice either with respect to the strength of the receptacle or its durability.

" A further object is that of constructing a receptacle which 'may readily be sealed, and which, when so sealed, will prevent any tampering with or withdrawal of its contents without giving obvious indication that such an attempt has been made.

A still further object is that of furnishing a unit of this character which will prevent any leakage onthe part of its contents, and which, moreover,

will guard such contents against evaporation o deterioration. An additional object is that of providing a receptacle, the several. parts of which may be expeditiously and inexpensively manufactured, largely by means of methods'and machinery as atpresentexisting, so that a unit will be produced which will offer at least the foregoing advantages, and which,

Fig. 4 is a similar view illustrating the second stage of such application; and 50 Fig. 5 illustrates the final stage of such applia cation.

' formed ofpaper, pulp orsimilanmaterial, and which'may be impregnated or coated in any de- 55 sired manner to prevent the escape of moisture therethrough, and also (if desired) to preserve the material of the body against deterioration. As illustrated-this body is shapedto provide a cylinder. This is inmany respects the preferred configuration, but it will be apparent that any "5 desired shape might be employed.

Such a body may have one of its end portions closed at the'time of its manufacture. Again, preferably, however, both ends are left open and are sealed by similar closure elements. While 10, these elements may be directly in contact with the faces of body ID, I have found that in order to guard against leakage, even in the case of extreme conditions, it is preferable to coat at least the end portions of the cylinder with a layer of 15 sealing material as hereinafter described. Such coating may conveniently be furnished by simply dipping the ends 'of the body into a fluid bath of the same, and this coating has been indicated at ll.

Now referring to the end seals for the body, and which have been generally identified by the reference numeral l2, it is observed that these are preferably formed of metal, and include end disks l3 domed outwardly towards the container end and 25 continued adjacent their edge portions in an upstanding fiange I4, which has an exterior diameter equal to the inner diameter of body In. Accordingly, a sealing contact will occur between the outer flange face and the inner receptacle face. 30 v Beyond this flange the seal is continued outwardly, as at l 5, for a distance corresponding substantially to the thickness of body I0, and beyond this outward portion Hi the seal extends upwardly and initially in a direction parallel to and in intimate contact with the outer face of the wall of body ID. This condition has been exemplified in Fig. 3, where that portion of the seal beyond the upwardly extended portion has been identified at It. Portion I6 is now swung inwardly as indi- 4.0

cated in Fig. 4, and the outer edge of the same is turned inwardly upon itself, as indicated at Hi. This inwardly turned portion or bead may, of course, be formed at any desired time, but in any event the parts are swung inwardly and forced into intimate contact with the outer face of body l0 in the manner shown in Fig. 5. a

In this figure it will be observed that the .bead -I 8 has been somewhat flattened, and that following a manipulation of the parts in accordance with the 1 v foregoing and by the use of a suitable clamping In these views, the numeral Ill-indicates a body mechanisrmthe outersurface of the seal provides a relatively enlarged base portion I9 within which those portions of the wall I0 adjacent its edge may be fully expanded. Immediately beyond the same is a relatively, constricted portion l1 whichprevents any accidental withdrawal of the wall In, in that throughout the zone of this portion the material of the wall is 'tightlycompressed. Beyond this portion l'l the outer part of the seal presents of bead l8 the parts are under relatively heavy compression. I

Now referring to the coating H, I have found that a number of substances may be employed.

For example, gum benzoin dissolved in alcohol or a latex compound may beutilized. This is especially effective, having in mind that the body Ill preferably comprises a laminated structure, and if no coating were employed air pockets might remain adjacent the edge or penetrate between the individual layers of laminations, and such pockets could result in oxidation of the receptacles contents, particularly in the case of oil. Also, the seal would be broken at this point and seepage might occur. However, by employing this coating, the end edges of body III are sealed, and this seal also includes a sealing of the individual layers of "such body.

It is, of course, apparent that while in certain respectsthe layer H is preferably to be applied by immersing the ends of the receptacle, it might likewise be applied by coating or filling the end seals with the material.

In any event, it will be appreciated that as a consequence of the foregoing structure, end members are furnished whichyin cooperation with] the container body, provide a multiplicity of sealing and keying zones such that accidental displacement or detachment of the seal is prevented. This will be true even if the receptacles are filled with relatively heavy material such as oil. More'- over, incident to these seals, it is found that any danger of the receptacle contents escaping or leaking is precluded, and this is especially trueif a coating such as that heretofore described is employed. Moreover, such a. coating serves to preclude spoilage or deterioration of the receptacles contents and, in effect, binds the end seals or members to the container body in such manner that they are, in effect, integral therewith.

It is additionally obvious that with a construction of this nature, the ends of the tube or container body are reinforced to such a. degree that any danger of crushing is avoided, even although the containers are subjected to a great amount of abuse.

1. A container including in combination a body presenting an'open end portion, an end seal for such portion and comprising a material layer from the edges of which an outwardly extending flange projects and whichis continued in the form ofan inwardly extending portion spaced from and parallel to said outwardly extending portion, the edge of said container being disposed between said outwardly and inwardly extended portions and with its inner and outer faces immediately adjacent such portions, said inwardly extending portion being of lesser height than said outwardly extending portion and being crimped and grooved inwardly to engage and compress the body of the container throughout a plurality of spaced zones, and a layer of plastic material interposed between the inwardly and outwardly extended portions and the adjacent container faces, said plastic layer contacting the outer and inner faces to a point beyond the outwardly and inwardly extended portions and merging into such portions.

2. A container including in combination a multi-ply body presenting an open end portion, an end seal for such portion and comprising a material layer from the edges of which an outwardly extending flange projects and which iscontinued in the form of an inwardly extending portion spaced from and parallel to said outwardly ex-.

. outer and irmer faces to a point beyond the outwardly and inwardly extended portions and 1 merging into such portions and said plastic layer also keying between the layers of the multi-ply.

body forming the container and adjacent the end edge thereof.
