Specification of Letters Patent.

Patented Feb. 8, 1921.

Applicationfiled April 19, 1918. Serial No. 229,502.

To all'whom it may concern:

Be'it known that I, EDGAR B. Brenna, a

citizen of the United States, and resident of St. Louis, Missouri, have invented certaln new and useful Improvements in -Paper Cans, of which the following is a specificapaper cans, and my object is to construct a square can wholly of paper, including its seams, and in such a manner as to be least subject to distortion after forming.

My improvements consist in the novel construction, arrangement and combination of parts as will be fully, clearly and concisely set forth, definitely pointed out inmy claim and illustrated by the accompanying drawings, in which Figure 1 is a plan view, on a reduced scale, of the blank, for the walls of the can.

Fig. 2 is a fragmental plan view of the blank for the can bottom,

Fig. 3 is an enlarged fragmental, sectional elevation, taken on the line 33 of Fig. 1

showing a crimp to form one of the can corners.

Fig. 4; is an enlarged fragmental sectional elevation, taken on the line 4-4 of Fig. 1, showing a stop bead for the lid.

Fig. 5 is an enlarged fragmental sectional elevation, taken on the line 5-5 of Fig. 1 showing a channel which facilitates the securement of the bottom.

Fig. 6 is a fragmental inverted plan view showing the bottom as secured to the walls.

Fi 7 is a sectional plan taken on the line 'lr' of Fig. 8, showing the lap seam of the side walls.

Fig. 8 is an elevation, partly in section, of the complete can.

Fig. 9 is a plan of a blank for the innermost ply of the lid.

Fig. 10 is a plan of a blank for the outermost ply of the lid.

Fig. 11 is a fragmental, inverted plan showing the folded arrangement of the corner elements of the innermost plypf the lid.

Fig. 12 is a view similar to Fig. 11 showing the folded arrangement of the corner elements of the outermost ply.

Fig. 13 is an inverted plan of the complete lid.

Fig. 1a is an edge view of the lid.

Fig. 15 is an'enlarged fragmental sectional elevation, taken 011 the line 15-15 of Fig. 13.

Fig. 16 is an enlarged fragment-a1 sectional elevation, taken on the line 16-l6 of F ig. 13, and

F ig, 17 is an enlarged fraginental sectional elevationtaken on the line 1.717 of Fig. 13.

Referring; to the drawings by numerals,

18 designates the full wall sections of the wall blank and 19 and 20 the end wall sections thereof, the section 20 having greater width than the section 19.

Extending the height of the blank between the wall sections are the sectionally curved creases 21, which as shown extend to the top margin, but terminate short of the bottom blank margin, but whose lengths or heights are co-extensive with the heights of the walls proper.

At the bottom end ofeach crease 21 there is a cutout or notch, 22, forming the crimping flanges 23 which serve to secure the bottom of the can to the walls, and in each flange 23, next the lower margin of the walls-proper and for their lengths is. a pressed channel 24.

Near the'upper margin of each wall section there is a stop bead 25, paralleling the said margin.

Fig. 1 shows an. inside face view of the wall blank, and in this illustration the creases 21 are-pressed outwardly.

The stop beads 25 are pressed outwardly and the pressed channels are in the inside facesonly of the material, as shown in Figs. 3, 4 and 5, respectively.

The bottom proper26 is substantially rectangular, with dimensions between its margins 27 equivalent to the widths of the wall sections, recited, and its corners 28 are rounded and with radii corresponding to the curvatures of the creases 21 of the wall blank.

Along each margin of the bottom and approximating their lengths, save for the is held and the wall blank is positioned therearound with its pressed channels disposed to receive the flanges of the bottom, and its curved creases 21 registering with the round corners of the bottom.

Then with glue or other adhesive, which is applied prior to the assembling, the wall blank is wrapped about the bottom, commencing with thesection 19, which is approximately a half wall, then the full wall sections 18 and finally the section 20, which has been gummed along its free edge for securing or seaming to the hall wall section 19, as shown in Fig. 7.

The flanges 23, are then turned as shown in Figs-6 and 8 to embrace the flanges o'E tial that the upper margins of the walls be held in tru square in order to permit ready placement and removal of the cover, and this is accomplished, between corners by the beads 25.

' The cover 18 made up of two blanks whose bodies 81 and 32am shaped to conform with the cross section of the can, that is, each substantially rectangular and with rounded corners 33 and 3 1 of radii substantially that of the radii of the can corners.

The body or blank 31, which is the inside ply of the'cover is preferably made from V relatively heavy or thick stock and along each margin provided with a flange 35 which extends or laps beyond the cut of the round corner 33 and each lapping is such as to bring the terminals of the flanges to abut each other at the center of the round corner when the flanges are turned to a right angle relative' to the body.

The body or blank 32 which is the outside ply of the cover, is relatively thin whereby ing or can constructed of two blanks each having it may serve as a finish and its body dimensions are substantially the same as the body or blank 31, and like the blank 31' its corners are rounded, and it is further provided with flanges 36, similar to the flanges35, of the inside blank, except that the extended ends thereof project beyond the cuts for the round corners, so that they may be relatively overlapped, and to completely overlie the extended ends of the flanges 35.

By preference the whole inside faceof the blank or body 32 is supplied with adhesive or gummed and thus formed over the heavier inside blank or body 31.

7 By reference to Figs; '13, 16 and 17 it will be noted that the relatively thin outer flanges 36 are adhesively secured over the margins of the round corners of the heavier body 31, and thus I am enabled to make a neat and 'flrmrflanged cover corner on a round-cornered square can,

The heights of the flanges of the cover are approximately equal to the distance between'the bead25 and the top edge of the can so the cover will be supported by the flanges and hencenot be subjected to tearing at their corners by jamming the cover over the can to the extent of the can-top edge breaking through the cover.

By reason of the copious application of adhesive to the relatively secured flanges of the bottom and walls I obtain more than a mere securing of the flanges, for when dried the adhesive serves to strengthen and stiflen the whole bottom end of the can.

I claim-- '7 ,As a new article of manufactur a can, constructed of a single blank of paper, of substantially square section and provided with round corners, said round corners being creased in the blank prior to the squarthe can, and an end closure tor the round corners and marginal flanges the flanges of the one blank otthe closure at each corner having combined lengths equal to the linear dimension of the corner and the flanges of the other blank having combined lengths in excess of the linear dimension of the corner. 1 V EDGAR B. BICKER.
