YFirearm Secession, and JAMES G. Burris,

all citizens o the United States, residing in the borough of Brooklyn, lsew "York cttw, in

the county o Kings and State of New i ark,

have invented certain new and useful lmprovements in Folding Paper Boxes, of which the following is a speeiiication.

This invention relates to folding paper boxes made ont of a blank having a middle plain zone creased into panels to form the four sides of tbe box, am tivo parallel finale hesive tape, or bye pasted flap forming en extension of one of the end panels, or by some equivalent method; but this makes a weak joint m a vulnerable place, and our invention has :for its object tu doau'ay with such a joint. We accomplish this by pro- Vriding a box wlxichlxas its joint at an interwith its ends united to form a tube.

" mediate line iu one of the side panels and the adjacent tiaps, and we also provide an imrored form of joint for this location.

represents a plan vietv ofthe blank for a box constructed according to our invention. Fig. 2 represents a perspective vieu' of said blank Fig. 3 represents'a similar view showin two of the flaps folded down to startthe Lbottom closure. Fig. 4 represents a similar vieu' of the box with closed bottom and open top. Fig.

-5 represents a similar vieu showing the box completely closed. Fig. 6 represents a plan view of a modified form of blank.

The blank shown in l? ig. 1 may be formed by any suitable method out of material such as straw-board, corrugated board, etc., in a single piece comprising;r a middle zone which consists of a line of intermediate

full panels

10, 11, 12 and

end artpanels

13, 14 to form the sides of the ox, together with two parallel marginal zones transversely slitted at'15. 15 to form

full flaps

ilaps

tne panels

11 and 13, le..v We also prefer to 'iorm the edge o one of the part-panels, as 33, with recesses :23 and the edge of the other, is, with complemental projections 24 constituting a dove-tail or interlocking joint. tvbcnthe blank ends are brought together. In constructing the box fromA the bis the latter is first. formed into a let tube by bringing its ends togetlier end interlocking the dove-tails and t en pasting a suitable strip or tape, such as a cloth tape 25 over the union. Fig. 2 shows this tube opened ont. into rectangular form. Since the joint. of this box occurs intermediate of one of the side panels and traverses both this panel and the adjacent a s it can be made much more secure and is ess vulnerable than the old forni of joint which it was customary to make at one of the corners between adjacent side panels. 'With this old corner jointthe sealing tape or the extension flap which united the panels could not. be extended bevond the upper and lower edges of these panels. and its ends were easilyv started, so that the joint was much inferior to our improved form and location of joint. It is to be noted. also that we retain the advantage of the old construction which enables the blank to be formed into a tube by joining its ends, and shipped lat in this doubled shape from the maker to the user, which tended blank. bile a box-blank could be shipped doubled without havin its ends joined. our joined blank or box-tu is more marketable than either an unjoined blank or a corner-joined one inA that it saves to the customer the time and labor of joining the ends, besides affording a more. secure an extensive joint and one whose extremities are protected in the complete box, as nereinafter tinted out. Y

The c ove-tails or interlocking recesses and

projections

23, 24, While notindispensable to our invention, serve to strengthen the joint. against pulling apart, and since they are lo cated in a flat. panel under the adhesive tape 25, we. prevent any springin of the yinterthc box. The panels are marked Vo6 from locking members which woud tend to uplock them or loosen the tape, as in certain causes it to oecu less room than a ullv exeach other and from the a s by crease-lines i meeting edges to form a secure joint. or

the plane of the inetaneesvrhere dereteiis here at a corner idiot with e dierentiy-arrenged blank. These doveeiis eis@ resist strain in enel i3. '.tl better than 4corner dore-tails, y reason of their lying K entirely within said piene.

it is of course not esscntiai that the ioint `'shall come exactly in the middle of the f panel ia. i4.. 1o

When the fiat. tube reaches the user and is to ,be formed into a box, it is opened out into a rectangular tube end one or' the ends ris reversed as shown in Fig. tend is then ready to receive its contents through the o enl top end, the weight. of said contents, if

ey are of a heavy character, serving to hold the adherentJ bottom a, .s under ressureend after the box has een lle the top iaV s may be closed in the seme manner as the ottoni flaps, that is by first bending in the

jointed flap

19, 20 carrying the end of tape 25, and its opposite flap 17, applying adhesive material if desired, and then bending in the other tia )s 16, 1S. This coiniletes the closure of t e box. and the top und ottoni joints may if desired be perfected by covering them with pasted strips 2G of paper or cloth.

Fi 6 shows a blank of the same form as in Flg. l, without the dove-tail interlocking members. and this blank may be made up into a tube and then into a box in the manner above-described.

le *M A e A W'e do not claim novelty for the blank shown 1n Fig. 6 as it has been proposed i to use a blank of this general form, but folded in a dilerentmanner, so that the top 'well ermed by the part-panels and the peroeps, wmcn are teit open or enjoined until the box is filled. This of course ren t' I ders :mgirectieeble the use of oor improved form of joint and the method o melting it. @er invention possesses the advantages, among others, that the blank can be parielly closed to form e tube es described, the K. l

gioint of 'which may taped to make e. strong union before being sent out. by the menueetorer, and our box furthermore does not require any jig or form in setting it up i to be filled.

We cleinn- .1. A collapsed tubular paper box, made from e blanleseored to form side panels and slit to form top and bottom -aps, the :loint of said tube being on a line intermediate one of the side panels and the adjacent flaps, the :deps of said blank being adapted to be bent over to form the top and bottom walls,

and a nested strip covering the joint-linc across t e jointed panel and aps and leaving the a is free to be folded or unfolded.

2. A co apsed tubular :iper box, ,made from a blank scored vto orm side panels and slit to form top and bottom flaps, the

joint. of said tube being on a line interme- .diate one of the side panels and the adjacent flaps, the meeting edges of the said joint beineP provided with interlockin dovetailed mem ers, the flaps of said bunk being adapted to be bent over to fol-m the top and bottom walls. and a pasted strip covering the joint line across the jointed panel and flaps and leaving the ilapsfree to be folded or unfolded.

In testimony whereof we have hereunto set our hands in the presence of two snb- I scribing witnesses, this second day of Muy GEORGE W. GAIR.
