J., assignor to Standard Container, Inc., Mon'tclair, N. J a corporation of New Jersey Application August 18, 1945, Serial No. 611,304
'This'invention relates to paper containers, and more particularly to an improvement in containers of the type used aspaper cans for the packaging of either dry or liquid stock, including stock packaged under gaseous pressure, An example of the type container to which the present invention relates is found in my Patent No.
2,304,684, dated December 8, 1942. In said patent, the advantages of affixing an end cap or closure member to the end of a tubular paper container body by means of an adhesively attached tubular paper strip, were fully set forth. The present invention-contemplates the utilization of such a paper strip for afflxing the anchoring ring or end wall of the container in place, but employs a different type of anchoring means and a double-thickness end wall having numerous features of novelty and utility.
An object of the present invention is an improved end cap for a container of this character which shall be of double thickness and thereby strongly reinforced; which shall have an interlocking engagement between the end walls, serving to not only securely unite them, but to also aid greatly in preventing leakage of the contents of the container between the layers of said end wall, as well as between the junction of said end wall and the body of the container.
Another object of the invention is to provide a closure means having all of the advantages of that disclosed in my above-mentioned prior patent, and at the same time providing a greatly strengthened, stiffened and leak-proof construction.
These and other objects are attained by the construction hereinafter described and more particularly pointed out in the claims appendedhereto.
Reference is to be had to the accompanying drawing, forming a part hereof, in which Fig, 1 is a vertical sectional view through the several parts which, when united as hereafter described, constitute the end closure for the container; Fig. 2 is a similar sectional view, showing the parts in their assembled relationship, with the assembly in readiness to have its parts interlocked; Fig. 3 is a sectional view showing the end closure in place at the end of a container body, and Fig. 4 is a side elevation of the end closure assembly of Fig. 2.
In Fig. 1 is shown the various parts employed in the end closure assembly, the part shown at M consisting of a thin, sheet-metal disk constituting an inner end wall of the closure, the same including a circumferential vertical wall portion.
3 Claims. (01. 229-55) Iiproyided at one end with an integral, radially fprojecting flange it which is subsequently turned down or bent over the edge of the paper strip 5,
as clearly shown in Figs. 2 to 4 inclusive. The base wall or bottom I! is formed with a raised portion or cup-like formation l8, this part including the vertical annular wall IS.
The outer closure member for the container is shown at 28, the same consisting of a relatively thin, sheet-metal disk having a radially project'- ing base flange 2! from which rises the cylindrical part 22 having a smaller-diameter cylindrical portion 23 extending integrally from it, as clearly seen in Fig. 1. The outer closure member 20 may, if desired, be a stamping of sheet metal.
At 5 is shown the paper strip or band which is made into cylindrical form by being wrapped about the surfaces l5 and 22 and which has its outer face adhesively coatedas at 25, or as an alternative, this face may be coated with the adhesive or cement just prior to being inserted into the end of the container body, the latter being shown at B.
The end closure unit in its assembled condition,
and just prior to interconnection of the parts 14 and 20 to thereby place it in readiness for insertion into a container body B, is shown in Figs. 2 and 3. It will therein be observed that certain portions of the end closure members [4 and 28 have been nested so that these parts serve to confine the paper strip 5 between the flanges l6 and 2|, It is to be noted that the external diameter of the part 23 is slightly less than the internal diameter of the part IS, the part 23 closely fits or nests within the part I9 and is surrounded thereby.
The tubular strip or paper band 5 extends around the wall I5 and the wall 22, and the flange I6 is bent or turned down over one edge of the paper strip so that the strip is thus confined between the turned-down flange l6 and the radiallyprojecting flange 2i on the outer end closure 20. By means of suitably applied pressure, the walls i9 and 23 are distorted laterally as clearly seen in Fig. 3, such distortion resulting in a lock seam serving to securely lock together the two end closure members it and 20,-the same then becoming, for all intents and purposes, a unitary structure.
The unit thus constructed, is placed inside of the end portion of the laminated paper or other fibrous material container body B, the cement or adhesive on the outer face 25 of the paper band or strip 5 having been rendered adherent by being moistened or otherwise treated before the insertion of the unit within the container, so that the paper strip 5 becomes firmly adhered to the inner face of wall of the container in the manner fully described in my Patent No. 2,304,684.
The radial flange 2 I, which then projects laterally beyond the container body B, is turned over mote, and a structure capable of withstanding very hard use is provided.
What I claim is: l r 1;. In a container, a tubular paper container body, a pair of disk-shaped end walls on saidcontainer body, said walls having complementary parts located within the container bodyand fitted one within the other and complementarily dis- 0 torted and thereby interlocked to hold said diskshaped walls together in overlying relation, said disk-shaped walls carrying flanges, and a paper strip located between the flanges and having a face adhesively attached to the container body.
2-. In a container, a tubular paper container body, a tubular paper strip adhesively attached to the inside face of said body, a double-walled end closure for the container body, said end 010- sure having parts of its walls located within the container body distorted to thereby interlock them and hold said walls in united relatiomthe innermost one of said walls having a flange bent over an edge of the paper strip, the outermost wall having a flange confining the paper strip between it and the first mentioned flange and also being bent over an end of the container body. v 3. In a container, a tubular paper container body, a pair of sheet metal disks having centrally located nested portions distorted to lock the disks together, the disks each having an edge flange, the flange on one of the disks being bent in a vdirection toward the flange on the other disk, a,
paper band confined between the flanges and ad- .hesively attached to the inside surface of the container body, one of the flanges being bent to form a double seam over the end of the container body.
