PACKING BOX.

Application filed January 7, 1920. Serial No. 850,051.

To all whom it may concm:

Be it known that I, JOHANNES RUDOLPH SURMANN, a citizen of Bremen, residing at Bremen, 156/160, am Wall, Germany, have invented certain new and useful Improvements in Packin Boxes, of which the following is a speci cation.

The invention is directed to a packing box, constructed of cardboard or the like, wherein the various sections are so interfolded and associated as to provide a closed box of unusual strength and durability without the necessity of any fastening for holding the various sections together.

It has heretofore been proposed to manufacture boxes or containers of cardboard by folding strips or ieces of particular form together, and has een also proposed to employ cardboard strips laid crosswise for packing goods. For example, it has been proposedto, take a strip of cardboard and fold it into five portions at relative right an les, then place it atthe joint upon the mi dle panel of a similar cardboard strip also folded into five portions, and then to sli the ends of the two strips under the mi dle panel of the first strip to form the box.

In accordance with the present invention, the cardboard strips are folded into five parts and are disposed at right angles or crosswise, with the middle panels of the two strips in register. The ends are then folded around a frame to complete the box. If desired, and as'contemplated, the frame be a strip folded into frame form with the ends disconnected and so arranged that such non-connected ends meet together in the middle of one of the sides of the main cardboard strips,then the improved box may be constructed with the strips adapted to be. arranged perfectly flat when not in box forming positions, to facilitate transportation.

The invention in its preferred form is illustrated in the accompanying drawings, in which:

Fig. 1 is a plan of the cardboard strips preferably corrugated in initial position.

Fig. 2 1s a perspective view of the frame.

Fig. 3 is'a perspective view of the completed box section.

Fig. 4 is a perspective view, showin the use of an additional frame structure, w ereby the box of Fig. 3 is provided with a flange extension to receive a cover.

The improved box is preferably constructed of cardboard or the like, and primarily of two substantially identical sections a and b, scored or adapted for folding along the predetermined lines 1, 2, 3, and 4 of each strip. The folding is such that between the lines 1 and 3 of each strip, there is presented a panel 5 having a size commensurate with that desired for the box, the sections between the lines of fold 3 and 4 and between the lines of fold 4 and the free end of each strip are commensurate with the desired depth of the box. In conjunction with the strips a and b, the improved box contemplates a frame d made u of cardboard and folded into rectangular orm commensurate with the desired size of box, the meeting ends of this strip being preferably arrange mid-length one side, as at c.

In forming the box, the strips a and b are arranged with the panels 5 in registry. The frame 41 is laid upon the box overlying the edges of the aligned panels and the projecting sections of the strips are folded around the edges of the frame. in an obvious manner. Thus the box shown in Fig. 3 is completed.

If it be desired that a box he formed provided with a cover, it is only necessar to duplicate the box formation shown in ig. 3, and to arrange in one of said box sections a strip 7', formed of cardboard and of a size to snugly fit within one of the box sections and project above the upper edge of the same, thus providing a flange to receive the other box section, formed as previously described, as a cover. The strip f forming the flange is also made of an unconnected stri the meeting edges of which are preferab y arranged at one corner of the box section at which the flange is positioned, as for example, at 6, Fig. 4.

I claim- 1. A separable cardboard box made u of three strips of card board having each f our folding lines, two of which strips being arranged in super-imposed relation forming a rectangular frame and set upon t bent to a e bottom,

the outer portions of said two first strips being bent around the said frame so as to 5 form triple closed side walls.

2. A separable card board box made up of three strips of card board having each four foldin lines, rangecl 10 double bottom, and the third bein rectangular frame and set upon two of which strips being arin super-imposed relation forming a bent to a e bottom,

the outer portions of said two first strips having sue a bight equal to the width of the said frame and being bent around the sides of the frame so as to form triple 1 closed and fixed side walls.

j In testimony whereof I affix my signature in the presence of two witnesses.
