2 Claims. ICI. 229-16) This invention relates to polygonal paperboard boxes and more particularly I;o a reinforced bot tom structure fr such boxes.

It is the object of the invention to provide a polygonal paperboard box of eight or more sides forming the vertical walls that can be folded flat m; shiprnent or storage and that has a bottom that isformed by fiats hinged to the vertlcal walls that interfit and fold to produce a bottom structu re w hieh has substantial load sustaining capacity' and that interiorly engages the vertical walls-Izdhold the box to shape.

With the above and other objects in view, the invention may be said to comprise the box as illustrated in the accompanyi'ng drawings and hereinafter described, together with such varia tions and modifications thereof as will be apparent to one skilled in the art to which the invention pe rtains.

Reference should be had to the accompanylng d'rawing's forming a part of this speclfication, inwhich:

Figure 1 is a perspective view of the box in inverted position;

Fig. 2 is a vertical section taken on the line indicated at 2-2 in Fig. 1;

Fig;-'3 is a perspective view cf the box in invett cl position showing the flaps whieh form the bottom structure; and

Fig. 4 is a plan view of the one-piece blank of whiehthe box is formed.

The box of the present invention is formed from a one-pieee paperboard blank which is divided by a series of parallel fold lines I0 into rectangularportions II, I2, I3, I4, I5, I6, II and I8 which form the vertical walls of the box and an end tabl9 at the edge o1. the wall portion II at one -encl of the blank which is adapted to be secured td the inner face of the Wall I0 to form the tubular body of the box.

The bottom of the box is formed by means of a seriesof flaps which are formed integrally with the vertical walls I I to I8 inclusive and hinged to their bottom edges. The walls II and I which in the completed box are dizmetrically opposite and parallel to one another, are each provlded with a pair o1 integral flaps 20 and 2I whlch a're separated by a narrow central slot 22. The flaps 20 and 2I serve as supportlng flaps for the bottom structure and are hingedly connected to the walls II and I5 by means oi fold llnes 23 whlch permit the fiaps to be moved to horizontal positlon as shown in Fig. 3. The slots 22 are centrally disposed so that when the flaps20 and 2I are dis'p0sed in horizontal position' the slots 22 2 are in alinement and disposed diametrically of the box bottom.

The walls I3 and I1 which are parallel to each ot her and at right angles to the walls II and I5 are each provided with an integral flap 24 that is of polygonal shape and that conforms to the bottom end of the box the peripheral edges o! the polygonal fiaps corresponding in length to the bottom edges of the vertical walls of the box, one edge of each of the polygonal flaps being integral with the vertical wal1 I3 or I'l and being hingeclly connected thereto by a fold line 25.

Each of the intermediate walls I2, I4, I6 and I8 has a triangular flap 26 hingedly connected thereto by means of a. fold line 21. Each of the triangular fiaps 26 has a side edge 28 which is disposed at an angle to the adjacent edge of a supportihg flap 2I or 22 such that when the flaps are positioned horizontally as shown in Fig. 3, the edges 28 abut the adjacent side edges of the flaps 20 and 2I to brace the same and stiften the bottom structure.

Each of the flaps 24 has a wide crease or donble fold line 29 extending diametrlcally across the same parallel the fold line 25 dividing the polygonal flap into two equal sections so that the outer end portions of the.fiaps may be inserted through the slots 22 and the outer halves of the fiaps folded against the interior faces o1 the flaps 20, 2I and 26 as shown in Fig. 2. Since the fiaps 24 each conforrn to the bottom end of the box, the outer end portions of the flaps folded against the inner faces of the flaps 20, 2I and 26 engage with the inner faces of the vertical walls II to I6 inclusive and hold the box against collapse. The flaps 20, 2I and 26 which lie between the inner and outer portions of the bottom forming flaps 24 also brace the walls of the box to retain the same in their proper positions.

II: is I;o be understood that in accordance with the provisions of the patent statutes, variations and modifications of the specific devlces herein shown and described may be made wlthout departing from the spirit of the invention.

What I claim is:

l. In a paperboard box having a pair of diametrically opposite parallel side walls, a second pair of diametrically opposite parallel side walls disposed at right angles to the side walls of the first pair and four side walls intermediate the side walls disposed at right angles to one another to form a tubular body octagonal in transverse section, a bottom structure comprising a pair o! supporting fiaps hlnged to the bottom edge o1 each o1 the parallel walls of the first pair. the

' supportlng flaps of each palr belng spaced apart to provlde a narrow elongated slol, therebetween.

the slots between said flaps being in allnement when the flaps are disposed in a transverse plane, a bracing flap hinged to the bottom edge of each of saicl intermediate walls, each o! said bracing flaps having an edge that abuts an edge of a supporting flap when the braclng and supporting flaps are disposed in a. transverse plane and two octagonal flaps, each hinged to one 01 said second pair of parallel walls and each conforming substantially to the transverse cross section o! the box, each of said octagonal flaps having a diametrical crease parallel to its hinged edge and providing a. hinged end sect.ion adapted to be inserted through the slots between the supporting flaps and folded against the inner faces of said supporting and bracing flaps to form a self sustaining knock down octagonal bottom closure structure having supporting parts hinged to all eight side walls.

2. A knock down paperboard box having eight parallel side walls joined edge to edge to form a tubular body that is octagonal in transverse section, each of a first pair of diametrlcally opposite side walls having a pair of bottom supporting flaps that are spaced apart to provide a narrow elongated slot therebetween, each of the four side Walls adjolning one 01 said first palr of side walls having a triangular bracing bottom flap hinged therebo each of said bracing flaps abutting the adjacent supporting flap in edge to edge each of the remaining diametrieally opposite side walls having an octagonal bottom flap hlnged thereto that substantially conforms the transverse section cf said shel1. each of said octagonal flaps having a diametrical crease parallel to its hinged edge and to the slots between said pairs of supporting flaps, whereby, when the braclng and su}aporting flaps are disposed in parallel transverse planes, the diametrically creased portions ot both of said octagonalflaps may be received in said slots with the ends cf the octagonal flaps folded back against the inner faces o! said supporting and bracing flaps to form a bottom closure structure of interlocked flaps integrally hinged to and supported by each o1 said elght side walls.
