KNOCKDOWN PAPER BOX.

SPECIFICATION formingpart of Letters Patent No. 432,885, dated July 22, 1890.

Application filed October 7, T889. Serial No. 326,221, (No model.)

To aZZ whom it may concern:

Be it known that I, ALBERT C. LOHMANN, a citizen of the United States, and a resident of Akron, county of Summit, and State of Ohio, have invented certain new and useful Improvements in Knockdown Paper Boxes, of which the following is a specification, the principle of the invention being herein explained, and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My-invention relates to knockdown paper boxes; and it consists of an improved manner of forming the bottom, whereby the cornerfold flap of said bottom when the box is in set-up and complete form is held in folded position by engagement with one of the side panels, which is formed free from said corner-fold flap.

Referring to the drawings, Figure 1 is a plan view of one form of box-blank. Fig. 2'

is a side view of-t-he box in partly-closed position. Fig. 3 is a second side view of the box in position more nearly closed than that shown in the previous figure. Fig. 4 is a side View of a complete box. Fig. 5 is aplan View of another form of blank. Fig. 6 is a plan View of this second form of box in partlyclosed position. Fig. 7 is a side view of the second form of box in partly-closed position. Fig. 8 is a side view of the complete box of the form shown in the two preceding figures.

A and B are, respectively, the front and rear panels of the box.

0 is the bottom panel, and D the two primary side panels, which have formed integral with them, respectively, and also with the opposite sides of bottom panel 0, bottom cornerfold flaps E. Said bottom corner-fold flaps have a diagonal scoreethat extends from the inner common corner 6' of said primary side panels. Said bottom panel and said cornerfold flaps outwardly to the diagonally-opposite free corner of said fold-flaps. Secondary side panels F are respectively formed free from said corner-fold flaps but integral with rear panel B. Top-fold panel Gis formed integral with front panel A, while top cornerfold flaps H are integral with panel G and side panels D. Said fold-flaps H are each provided with diagonal scores h, that extend outwardly from the corner point of juncture of said fold-flap H with panel G and side panels D. Slits f are formed in the secondary side panels F and tongues 01, formed in the primary side panels D, respectively, fit into said slits and serve to hold said primary and secondary side panels in close engagement with each other when the box is in closed position. A top tuck-fold J is formed integral with rear panel B. The transverse width of side panels D is substantially equal to the width of bottom corner-fold flap E, and also with the width of side flaps F, whereby the body portion of the blank isrectangular in form and little or no paper is wasted in cutting out the same. Panels F are respectively separated from their adjacent bottom corner-fold flaps E by a out, while the remaining panels are defined by the usual scores, whereby they may be readily bent or folded into position when it is desired to set up the box in complete form.

To setup the box shown in Figs. 1, 2, 3, and4= in its complete form bottom corner-fold flaps E,

are folded upon themselves along the line of the score 6, as shown in Fig. 2, until the adjacent ends (1 of primary side panel D and bottom panel ,C are in close proximity with each other, being separated merely by the folded thickness of fold-flap E. The secondary side panels F are then folded inwardly until they are in engagement with the inner faces of primary side panels D, whereupon tongues d are interlocked with the walls of slits f. WVhen in this position, the ends f of the panels F.are in engagement with and have edge bearing against the folded cornerfiaps E along the line of scores (1', and by their hearing prevent said fold-flaps from unfolding. Thus a tight solid bottom is formed, and all liability of leakage of the box contents obviated.

Referring to the form shown in Figs. 5, 6,

"7, and 8, the proportions are varied from the form shown in Fig. 1; butin allessentials the forms are the same. Fold-flaps H are formed plain without scores, and top tuck-flap .l' is provided with a tongue.

The proportions of panels andfiaps may be varied without departing from the principle of my invention.

2 I j 432,895 b The foregoing description and accompanying drawings set forth in detail forms in embodiment of my invention; but change may be made therein, provided the principles of formation respectively recited in the following claim are employed.

I therefore-particularly point out and dis tinctly claim as my inventionbox, the c0mbinapanels F, the end of said panels F, respectively, engaging with and having edge bear- 15 ing on said corner-fold flaps along the line of jilnction of said corner-fold flaps with said panels D. V

In testimony that I claimthe foregoing to be my invention I have hereunto set my hand 20 this 2d day of October, A. D. 1889.
