RATION OI AMERICA, OF CHICAGO, ILLINOIS, A CORPORA- Application filed April 11, 1925. Serial No. 22,888.

This invention relates to i boxes made of fibre or paper sists of the matters hereina and more particularly pointed out in the appended claim.

The invention relates more especially to mprovements in v board and contransverse section through the box, and in fter described part an end elevation.

Such boxes are of great strength, more particularly in Figures 1 to 5;--the particularly at the ends and are in wide use. box is made up of a body "blank 10 and of In many cases it is desirable to use what w like n a k 1, 11. Th b dy blank is known as the top-loader -that is to is provided with parallel, longitudinally exsay, a box wherein the tubular body of the tending crease lines 12, which divide said box includes-flaps or cover wings adapted to blank into a bottom part 13, two side parts ends of the box, which are both ap open one side of the box and to close on the 14, 14 and narrow cover flaps or wings 15, plied and 15. The end blanks 11 are each cut and Figure 8 is a view in which are shown the secured to the body when the box is set up creased to provide an end wall l6, two narv for loading. The object of the present inrow side flaps 17 17 ,\a narrow bottom flap vention is to provide a recessed end box, 18, and a narrow flap 19 at the top to which with all the advantages due to the construcis connected a cover flap extension 20, which tion of the ends of such a box,

The box-is set up and the blanks are at r loading after tached together in the well-known manner in secured which recessed end boxes are made, with the in place and to be closed and sealed after narrow side flaps 17, 17 securedto the mar;

After the box is packed and ready for sealing the Figure 2 is a view in.perspective shogving narrow " cover wings 15, 15. connected to the in K nFigure 3' are shown pl several which goto m down on-the' contents of.the box and the anvieivs of the end cover flap extensions 20 connectedlto ake up the box. the end blanks are then folded down upon I the box partially opened up ready for sides 14, 14 of the body blank are turned top of 'the'side wings 15, 15, whereupon'the box is sealed by the application of a transversely-extending sealing strip 22, as shown in Figures 1 and 5.

It will be noted from an examination of Figure 5 that when theend flap extensions 20, 20 are folded down upon top of the side wings 15, 15, as above described, the marginal parts of the wings 15, near the ends of the box are embraced between the narrow flap 19 at the top of the end wall 16 and the end cover flap extension 20.

Thus not only is a closure made, Without gaps, adjacent the end wall of the box,-but

in addition, a very strong construction is produced.

The one sealing strip 22 efiiciently' closes and seals the box. But, if desired and for purposes of additional strength, staples may be applied to rigidly connect the cover flap extensions 20, the flaps 19 and the marginalparts of the side wings 15 embraced between them, rigidly together, as indicated by the staples shown at 25 in dotted lines in Fig-.

ure 1. a I

The construction described presents a recessed end box in the form of a"top .loader and has. allthe advantages of strength at the ends of such a box, combined with the convenience of packing of a top loader? In addition, it has the advantage that the box may be absolutely sealed with the use of the one sealing strip, where, heretofore, it has been necessary to use three sealing strips.

Instead of the sealing strip, the cover flap extensions 20, 20 may be sealed and attached to the cover wings 15, 15 (and to each other at their ends, when they overlap) by cement,

silica or other suitable material generally used in the art for attaching a board in flat engagement with another paper board. .In

66 blank is dispensed with, there being but the 7 single cover flap extension 2O at the top a of said blank. Here, again, the end cover flap extensions are'made of such length as to butt together, asshown in Figure 6, or to overlap, as shown in Figure 10. But, they are folded down uponthe narrow side cover wings 15 of the body and are at-- tached together by a single sealing strip 22 as before.

Both types ofbox illustrated represent manifestly a considerable saving in material when compared to the usual top loadergi since the necessity for extending the cover wings 15, 15 to cover the entire top of the box is eliminated.

' I claim as my invention A top loading recessed end box comprising a body blank and two end blanks, the body blank being creased to provide the bottom and two sides of the box and two side cover Wings, each end blank being-cut and creased to provide an'end of the box, with narrow strips-at the sides, bottom and top thereof, the side and bottom strips being attached within the marginal end of the body blank so that the end of the box is recessed within said body, and the top strip having a cover extension which folds back onsaid top strip, the two side cover wings resting on the end top strips, and the two top cover extensions folding down upon the side cover wings and being sealed thereon, the side, bottom and top strips of each end blank cooperating with the body of the box and the top cover extensions to form an outwardly extending reinforcing rib at each end of the box.

In testimony that I claim the foregoing as myinvention, I aflix my signature this 8th day of April, A. D. 1925.

HARRISON B. WALTER.
