Claims.

My invention relates to set-up boxes and has for its object the making of a complete box of one piece of cardboard and a paper covering, to form a single unit, designed to produce a complete box including a cover.

A further object of the invention is to produce a box which can be used as a mailing carton for merchandise and whereby said merchandise may be placed in the body of the box, the cover closed down upon the body and the box sealed by dampening the extended glued flaps and sticking them to the under portion of the box, thus avoiding the necessity of additional wrapping or tying of the package. The box as thus far used has been manufactured in relatively small sizes, adapting them for enclosing books. handkerchiefs, hosiery, etc., for shipment.

With the above and other objects in view as will be hereinafter noted the invention consists,

in certain novel details of construction and alignment of parts as will be hereinafter fully described, illustrated in the accompanying drawing and specifically claimed.

In the accompanying drawing forming a part a of this specification:

Fig. 1 illustrates a blank cut from cardboard and sheet paper, ready for the formation of the box.

Fig. 2 shows a perspective view of the complete box, in an open position, after being set up and wrapped.

Fig. 3 shows a bottom perspective view of the box in a closed position with its overlying paper edges glued down upon the bottom to form a seal.

Fig. 4 shows an enlarged cross section through one edge portion of the box better to illustrate the two materials of which the box is formed and the underlying sealing flap.

Fig. 5 shows a bottom perspective view of a modified form of box in closed position, having its sealing flap running lengthwise or at a right angle to those shown in Fig. 3, and including metal fastening means as shown in Fig. 5, and

Fig. 6 shows a cross section on line 6 6 of Fig. 5, through one edge portion of the modified form of box shown in Fig. 5. I

In forming my box, a blank is cut and scored by suitable dies or otherwise from a sheet of cardboard or other pliable material. In practice a number of such blanks are cut at a single operation and the paper blanks are somewhat similarly out. The cardboard blanks are first put into a folding machine where they are folded and the paper blanks separately glued and attached thereto, one at a time, the corners being first united by overlapped portions of the cover, and pressed together while the stock is yet damp, with the exception of the sealing flaps h, which having been glued, are left to dry, as the box is 5 discharged from the machine in an open position.

The cover portion of the box is closed down on the body portion of the box by hand after the box is discharged from the machine, with 19 the sealing flaps freely projecting from the edges of the box.

In Fig. l, I have illustrated both a cardboard blank A as seen on the near side and a paper blank B on the underside which serves as covu ering for the finished box. The blanks when thus united are of a slightly greater thickness and comprises the required necessary stock for the formation of both the body C and cover portion D of the box. The upper or cover portion D of the blank shown in Fig. 1 may, if preferred and as shown, be slightly larger in length and width than the lower or body portion C, so that when the box is formed and closed the cover will more readily fit over and close the body portion, preparatory to being sealed.

Referring again to Fig. l the dimensions of the bottom i of the body portion C of the box are represented by the dotted lines a, which indicate scoring of the cardboard along which the front member I) and the opposite side members H are folded to an upright position as indicated in Fig. 2. The glued tabs dd of the paper covering blank B are folded around the adjoining ends or corner portion of the front member b and the side members 0-0 as indicated by dotted lines in Figs. 2 and 3, which serves to tie the corners of the body of the box together.

The two glued side portions f--f and the glued face of the front edge portion 9 of the paper covering are next turned over and down upon the inner face of the sides and front of the body portion of the box during the further operations on the body.

The integral cover portion D has simultane- 46 ously been somewhat similarly folded as shown in Fig. 2. In this connection the opposite side portions c'c' and the front portion b is folded up at a right angle to the base along the scored lines a whereupon the glued tabs d of the pa- 50 per covering are applied around the corners formed by the joining of the members 0' and b. The glued edge portion a is next moistened and laid over on and glued to the inner face of the front edge portion b of the cardboard which com- I pletes the formation of the box except for the closing of the same and the sealing. The latter is accomplished when the box is packed by first moistening the glued free edge portions h of the paper covering, which now extends from the sides and pressing them in under the edge of opposite sides c and glued to the underside of the bottom i as shown in Figs. 3 and 4. This obviously serves to hold the cover in place upon the body after the same has been filled with merchandise.

In Fig. 4, it will more clearly be seen how the covering paper of the body C extends across the under side of the bottom portion and then up over the sides 0 and finally disposed against and glued to the inner face of the said side member 0. The same construction is followed out in the formation of the cover or top portion B except on the sides where the sealing flaps h are provided, the latter being left freely extended as shown in Figs. 1 and 2 until the box is packed, whereupon the flaps h are laid in and stuck against the underside of the bottom i of the body as shown in Figs. 3, 4 and 5.

In the modified form illustrated in Figs. 5 and 6,1 have shown a single glued sealing flap h which in this case extends inward along the front edge portion b of the paper covering and extending crosswise, and is laid in under the front edge portion of the bottom 2 for sealing. This can be accomplished as in the other form, by first moistening the glued face of the flap and folding it in under and against the bottom i disposed with and cover held down by a suitable metal fastening E as indicated in Figs. 5 and 6.

The means for sealing the box as above described is employed when the box and its contents are to be mailed as first class matter, but if it is to be mailed as second class matter the sealing of the flap is not resorted to but metal clips E are employed instead, see Figs. 5 and 6, which is shown secured to the inner sides of the body member and left for the time being to project upward as indicated by dotted lines in Fig. 6. These clips, two of which are employed, have pointed ends that serve to readily puncture the edge portion of the cover in the manner also indicated by dotted lines in Fig. 6, in position to be bent over the opposite top edge portion of the cover and down upon the side so as to form a temporary fastening which can readily be opened should occasion require. While this metal fastening means is shown only in the modified form illustrated in Figs. 5 and 6, yet it will be obvious that the same could be used in connection with the form shown in Figs. 2, 3 and 4. This fastening can also be used along the front edge of the box if preferred instead of the two sides.

From the foregoing it will be understood that the body and cover members of the box are constructed simultaneously and very much in the same manner except that the blank for one member may be enough larger than that of the other so that when the box is formed, one member may be freely closed over the other as shown I in Fig. 4. It will also be understood that the paper blanks may be printed or colored or decorated in any suitable manner while in the flat form. The box as before suggested is particularly desirable for mailing purposes in which case such printing as may be applied can be of a character suitable for addressing and mailing purses. Having thus described my invention what 1 claim and desire to secure by Letters Patent is: 1. A paper box formed of a cardboard base and an attached paper covering, including a body portion and an associated integral cover foldably connected thereto, both the body and cover portion being scored along their side and front portions and having their sides and front portions turned up along the scored lines to form sides and front members of the box, the paper covering of the body being turned in and glued to the inner face of the said sides and front members of the body, there being an integral glued paper tab portion extended around and glued over the adjoining ends forming the corner portions of the box, the front edge of the paper covering opposite the foldable connection of cover and body being extended along its elongated edge and glued forming a "flap along its outer edge laid over on and sealed to the underside of the associated box member when closed to seal the same and form a sealed closure of the box along its front edge, one portion of the blank for the box being slightly larger than the other better to allow the cover and body to close, one within the other.

2. A paper box formed of a cardboard base and having a paper covering and including a body portion and an associated integral cover foldably connected thereto, both the body and cover portion being scored along their sides and front portions and having their sides and front portions turned up along the scored lines to form sides and front members of the box, the paper covering secured to the cover being also secured to the outer face of the sides and the front portion of the cover and having integral glued paper flaps extended beyond the edges of said cover side portions and laid over on the associated box member and when closed secured to its underside to seal the said edges of the cover to the body, the front portion of the paper cover opposite to the foldable connection of cover and body having an extended glued paper flap along its outer edge integral with said paper covering and laid over on and sealed to the underside of the body to seal the same and form a sealed closure of the box along its two opposite edges.

3. A paper box formed of a cardboard base and an attached paper covering, including a body and an associated integral coverfoldably connected to said body, both the body and cover having their sides and front portions turned up to form side and front walls, the paper covering of the body being turned in and glued to the inner faces of the side walls of the body, and the paper covering on said cover being extended beyond the edge of a wall of the cover and glued forming a flap laid over on and sealed to the underside of the body when the box is sealed closed.

4. A paper box formed of a cardboard base and an attached paper covering, including a body and an associated integral cover foldably connected along their rear edges, both the body and cover having their side and front portions turned up to form side and front walls at the edges of the body and cover, the paper covering of the body being turned in and glued to the inner faces of the walls of the body, the front edge of the paper covering opposite the foldable connection of the cover and body being extended beyond the edge of the front wall of the cover and glued forming a flap extending from the free edge of such cover wall and laid over on and sealed to the underside of the body when the box is moms? 3 10 body-being turned in and glued to the inner faces of the walls of the body, the edges of said paper covering at the sides of said cover being extended beyond the edges of the side walls of the cover and glued forming flaps extending from the free edges of such cover walls and laid over on and sealed to the underside of the body when the box is closed to seal the same and form a sealed closure along the side edges of the body and cover.
