CONTAINER Fred B. Williams, Jackson Heights, Long Island,

N. Y., assignor to Bandeau Corporation, a corporation of Delaware Application December 14, 1937, Serial No. 179,691

This invention relates to containers.

It is an object of this invention to provide a new and improved container of the fibre class having metallic ends, in which the contents may be completely insulated from all metallic parts and from the edge of the paper wall.

In the co-pending application of Hermann G. Seybold, Serial Number 149,583, there is disclosed a container of the fiber class in which a metal strip is wound between the fibre layers forming the container wall at the ends of the wall serving a container of the fibre class in which a metal and the fibre of the container wall is impregnated against the liquid. I For most purposes such containers meetevery requirement. For some liquid, however, it is desirable to insulate the contents completely from the metal end, or from the metal bonding strip or from the fibre wall.

It is an object of this invention to provide a container of the character described which will completely insulate the contents from the fibre wall or with the metal ends without the necessity of a double package and in the form of a container which. can be handled, filled and sealed by the same machinery as though the insulation were not provided.

The invention accordingly comprises an article of manufacture possessing the features, properties and the relation of elements which will be exemplified in the article hereinafter described and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature andobjects of the invention, reference should be had to the following detailed description, taken inconnection with the accompanying drawing, in

which:

Figure 1 is a central section of a container embodying this invention, after the head is in place to close the container and before it has been crimped in place.

Figure 2 is a similar view after the first crimping operation.

Figure 3 is a similar view after the second crimping operation.

Figures 4 and 5 are half sectional views of modifications.

In the drawing the numeral III represents the convolutely wound paper side wall, II the metal binding strip embedded in the container wall, and

I! the container end having a central cup shaped portion l3 fitting snugly within the container wall and an outwardly extending flange I. These parts are in accordance with the disclosure of the said Seybold, application.

s Claim- (01. 229-5.!)

In accordance with this invention the container wall is lined with an insulating strip of paper l5 extending above and below the container wall proper as shown at l6 by an amount to enter into the end-crimp as shown at H and a disc shaped piece of paper i8 fits over the interior of each end of the can having a diameter larger thanthe end wall so as to provide a peripheral wall i9 which also may be included in the crimped position of the can end. This peripheral portion may, if

desired, have a diameter less than the full diameter of'the end of the can so that the extension a of the end may first be crimped around the paper layers and .the binding strip before the final crimping tight against the container wall.

With this construction no seepage out of the crack at the crimp can reach the exposed and relatively more porous end of the paper wall and no contact can occur between the contents of the can and the paper wall or the metal end since both are separated clear into the seal.

Moreover, the can thus described can be handled, filled and sealed by the machinery ordinarily employed for the purpose without creating a new filling problem. Moreover, with this construction for many purposes a cheaper wall may be employed and yet the contents can be fully protected.

The form of the invention disclosed in Figure 4 is intended for use with commodities which are not adversely affected by contact with the metal end, if the latter be suitably protected with a pro tective coating, and in this case the paper disc i8 is omitted.

The form of the invention disclosed in Figure 5 relies uponthe inner lining IE to assist in holding the end cap in place and omits the embedded metal strip I I Since certain changes may be made in the above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained inthe above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention, which, as a matter of language, might be said to fall therebetween.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is: y

l. A container of the character described comprising'in combination a rigid paper cylindrical wall having a metal strip embedded therein at 65 one end and extending beyond said end, a paper lining within said wall extending beyond the end of said wall, a metal end for said container crimped with said metal strip and said extended end 01- said lining about the end of said rigid wall.

2. A container of the character described comprising in combination a, rigid paper cylindrical wall having a metal strip embedded therein at one end and extending beyond said end, a paper lining within said wall extending beyond the end of said wall, a metal end for said container having a central body portion closely fitting within said rigid wall and said lining and a peripheral flange crimped with the extended end of said lining and said metal strip about the end of said rigid wall.

3. A container of the character described comprising in combination a rigid paper cylindrical wall having a metal strip embedded in its end and extending out from the end of said wall, a metal end for said container, a paper lining for said end comprising a disc of paper, said end and said extended body of said metal strip and said lining being crimped together about the end of said rigid wall.

4. A container of the character described comprising in combination a rigid paper cylindrical wall having a metal strip embedded in its end and extending out from the end of said wall, a metal end for said container having a central body portion adapted to fit closely within said rigid wall and a peripheral flange, a paper lining for said and comprising a disc otipaper, said peripheral flange and said extended body of said metal strip and said lining being crimped together about the end of said rigid wall.

5. A container of the character described comprising in combination a rigid cylindrical paper wall, a lining within said paper wall extending beyond the end thereof, a metal strip embedded within said paper wall and extending beyond the end thereof, an end for said container, a lining for said end comprising a paper disc, said end and the extended portions 01 said first mentioned lining and the extended portion of said strip and the periphery of said disc being crimped together about said rigid wall.

6. A container of the character described comprising ln combination a rigid cylindrical paper wall, a lining within said paper wall extending beyond the end thereof, a metal strip embedded within said paper wall and extending beyond the end thereof, an end for said container having a central body portion fitting closely within said wall and said lining and a peripheral flange, a I

lining for said end comprising a paper disc, said peripheral flange and the extended portions of said first mentioned lining and the extended portion of said strip and the periphery of said disc being crimped together about said rigid wall.

7. A device in accordance with claim 2 in which the flange is crimped over the edge of the metal strip and bent downwardly and inwardly against the outside wall of the container.

8, A device in accordance with claim 6 in which the flange of the end is crimped over the metal strip and bent downwardly and inwardly against the outside of the paper wall.
