CONTAINER.

Specification of Letters Patent.

Patented May 15, Torr.

Application filed July 14, 1915. Serial No. 39,869.

To all whom it may concern Be it known that I, Enxics'r O. lVImnLocK,

a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Containers, of which the following is a specification. I The invention relates to containers and more particularly to closures for containers or cans that are formed wholly or in part of paper or fibrous material. The invention seeks to provide improved means for securing the container cap or cover in place. A further object of the invention is to provide improved means for sealing the can or container in water tight fashion so that the same can be sterilized and used for hot liquids, as Well as other purposes, without leaking'or loosening the parts. Further objects are to provide improved sealing means that are readily detachable to afford access to the contents of the container without the use of instruments or tools; to provide means for, reinforcing and protecting the ends of the can or container from injury; and to provide improved sealing means of such a character that any attempt to open or tamper with the container will be readily detected.

The invention consists in the features of improvement hereinafter set forth, illustrated in the preferred forms in the accompanying drawings and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a round can orcontainer with parts of its body portion and cap removed to more clearly illustrate the improved sealing means.

Figs. 2 and 3 are detailed plan and sectional views illustrating the manner of applying the in'lproved sealing or binding strip. Figs. 4 and 5 are detailed sectional views of modifications.

The improved binding or sealing strip can be applied to cans and other containers of any desired shape and havi'ngvariously arranged lipped openings. In Fig. 1 a cylindrical can or container is illustrated. The same comprises a cylindrical body portion A preferably formed of heavy paper or pasteboard and open at its ends. Paper or cardboard caps or covers B having outturned flanges B fit snugly within the open ends or lips of the body portion A. A binding strip (7 is formed of soft, annealed or non-elastic metal and is preferably formed of soft annealed wire and is bent back and forth upon itself to form a plurality of connected, overlapping loops. The loops are bent transversely midway between the edges of the sealing strip, preferably to the form shown in Fig. 3, and the strip is then placed over the flange B of the cap or cover and over the edge or lip of the body A of the container, as shown in Figs. 2 and The opposite end portions of the loops are then pressed or firmly clamped upon'the flange and edge or lip of the body portion, as shown in Fig. 1, to thereby secure the cover 111 place.

In the preferred embodiment of the invention, the can body A and cover Bare formed of waterproofed paper or other fibrous material, and the loops are pressed or clamped against the cover flange and edge of the body portion tosuch an extent that they are embedded to a greater or less degree in the fibrous material of which these parts are made, to thereby form a watertight joint between the can body and its cover. If desired, the tool employed for compressing the looped sealing strip can be provided with means for forming corresponding offsets in the clamped portions, as indicated at C in Fig. 4 to thereby provide additional security in the joint between-the cap or cover B and body portion A.

The improved metal binding strip, as stated, is formed of soft. annealed or nonelastic metal and is preferably formed of soft annealed wire and is flexible so that it can readily be applied for securing the caps or covers of different shapes in place. If either the body portion of the container. or the closure therefor, or both, are formed of 'aterproofed fibrous material, the binding strip serves to form an effective water-tight joint without necessitating the use of adhesive sealing material. l urthermore. the sealing strip can be readily detached to permit the removal of the cap or closure and thereby afford access to the contents of the container without necessitating the use of tools to open the same. For convenience, in detaching the retainer strip, the latter is preferably formed of a single continuous piece of wire and at one end is provided with an extension I) which can be conveniently grasped to remove the sealing strip. In the form shown, the part D extends'inwardly over and in snug contact with the face of the cap or cover 13. When once removed, it would be extremely difficult to replace the same without leaving evidence of the fact that it had been removed, since the application of the sealing strip indents the fibrous material of Which the body portion or cap, or botlnare formed, and since it would be practically impossible to open the compressed lips and reapply the same neatly and in exact alinement With such indentations. The sealing strip also serves to reinforce and protect the end portions of the paper can or container.

In the form shown in Fig. 5, the container A is formed of glass or the like. Its mouth or opening is provided with a beaded lip a, an inwardly project-ing shoulder a and a recess a between the loop and the shoulder. In this form, the sealing strip C serves to force the edge or flange B of the paper cover B into the recess a so that the cover is secured in place in liquid-tight fashlon.

It is obvious that numerous changes may be made in the details set forth without departure from the essentials of the invention as defined in the claims.

I claim as my invention 1. A container comprising a body,having an opening therein, a cap for said opening, one of saidparts having an parallel to the edge portion 0 the other part, and a securing strip of soft, annealed metal bent over and compressed upon the flange and edge portion of said parts to secure said cap in place.

2. A container comprising a body having an opening therein, a cap for said opening,

one of said parts having an edge flange par-f allel to the edge; portion of the other part and one of "said parts being formed of 'fibrous,,- yielding material, and a flexible stripof soft, non-elastic metal bent over and compressed upon the flange and edge portion of said parts to secure said cap in place and form a tight joint between the same and the body of said container.

3. A container comprising a body having an opening therein, a cap for said opening, one of said parts having an edge flange parallel to the edge portion of the other part, and a flexible strip formed of soft, an-

nealed metal and consisting of a series of connected loops bent over and compressed upon the flange and edge portion of said parts to secure said cap in place.

A. A container comprising a body having an opening therein, a cap for said opening, one of said parts having an edge flange parallel to the edge portion of the other part and said parts being formed of yielding, fibrous material, and a flexible strip of dge flange,

soft, annealed metal and consisting of a series of connected loops bent over and compressed upon the flange and edge portion of said parts to secure said cap in place and form a tight oint between the same and the body of said container.

5. In closures, the combination of a body portion open'at its end, a cap having an outturned flange fitting within said opening, and a securing strip formed of soft, nonelastic metal and consisting of a series of connected loops bent over and compressed upon said flange and the edge of said body portion. i

6. In closures, the combination of a body portion at its end, a cap formed of fibrous material and having an outturned flange fitting Within said opening, and a detachable sealing strip of soft, non-elastic metal bent over and compressed upon said flange and the edge of said body portion to form a tight oint between the same.

7. In closures, the combination of a body portion open at its end, a cap having an outturned flange fitting within said opening, said parts being formed of fibrous material, and a detachable sealing strip of soft, nonelastic metal bent back and forth upon itself to form a plurality of loops, said loops being bent over and compressed upon the flange of said cap and the edge of said body portion and clamping the same together to form a tight joint.

8. In closures, the combination of a body portion open at its ends, a cap having an outturnedflange fitting within said opening, one of. said parts being formed of fibrous mater al, and a,cont1nuous, flexible, sealing strip of soft, non-elastic metal bent over and compressed upon the edge of said body portion and the flange of said cap to secure the same in place in moisture-tight fashion, said strip having an end portion extending inwardly over the face of said cap and adapted to be grasped to detach. said strip.

9. A flexible sealing strip disconnected at its ends and bent back and forth upon itself to form a plurality of loops, said loops being bent transversely to form a series of connectedU-shaped clamps adapted to embrace thc'overlapping edges of a container and its closure, said strip being formed of soft, non-elastic, annealed wire, whereby said U-shaped clamps are adapted to be contracted in applying said sealing strip and expanded in removing the same without tending to recover the shape from which they are forced in the application or'removal of the strip, substantially as described.
