A collapsible container formed of paperboard which can be folded one way for shipping purposes and an alternate way for display purposes.

SUMMARY OF THE INVENTION 
This invention relates to paperboard containers and more particularly to 
containers which are adapted to be used for both shipping and display. 
It is an object of the invention to provide a container of the type 
described which has a plurality of fold lines in certain of the panels 
which will permit the structure to be folded in one way to provide a 
shipping container and to be folded in an alternate way to provide a 
display container. 
These and other objects of the invention will be apparent from an 
examination of the following description and drawings.

DESCRIPTION OF THE INVENTION 
Referring now to the drawings for a better understanding of the invention, 
it will be seen that the basic structure T illustrated in FIG. 2 and 
formed from a unitary blank B of foldable paperboard illustrated in FIG. 
1, may be either folded into the form of a closed shipping container SC as 
illustrated in FIG. 4, or may be alternately folded into the form of a 
display container DC as illustrated in FIG. 7. 
As best seen in FIGS. 1 and 2, the structure includes a body portion having 
a front wall 10 and a rear wall 12 which are interconnected by a pair of 
side walls 14 and a glue strip 16, all of which are foldably joined to 
each other in side by side relation along fold lines 17 to form the 
tubular structure T illustrated in FIG. 2. 
The lower end of the structure may be provided with a plurality of bottom 
closure flaps 18 foldably joined to front, rear and side walls 10, 12 and 
14 along fold lines 19. The flaps may be folded and secured in overlapped 
relation in a conventional manner. 
The novel portion of the invention relates to the closure arrangement for 
the upper end of the container and includes front, rear and side closure 
flaps 20, 22 and 24, respectively, and an extension 26 of glue strip 16, 
all of which are foldably joined to related walls of the body along 
aligned fold lines 27 and which are foldably joined to each other along 
fold lines 29 which are aligned with the fold lines which join the body 
walls and glue strip to each other. 
The invention includes the provision of a plurality of fold lines in 
certain of the walls and flaps, as hereinafter described, which enable the 
structure to be folded either into the form of the shipping container SC 
or the display container DC. 
Each side closure flap includes a fold line 31 which extends from fold line 
27 to the opposite edge of the flap and which is located midway between 
and parallel to related fold lines 29. Flap 24 also includes a pair of 
upwardly converging fold lines 33 which extend diagonally from the lower 
corners of the flap to the point where fold line 31 intersects the free 
edge of the flap. 
Front wall 10 includes a transverse fold line which extends across the wall 
between related fold lines 17 and which is located between and parallel to 
related fold lines 19 and 27. Wall 10 also includes a pair of upwardly 
converging fold lines 37 which extend from the intersections of fold lines 
35 and 17 upwardly through front closure flap 20 to the approximate 
midpoint of the free edge of flap 20. 
Each side wall 14 includes a fold line 39 which extends from the 
intersection of fold lines 35 and 17 diagonally upward and rearward 
through related side closure flap 24 to the upper rear corner of flap 24. 
The previously described fold lines in combination with each other and with 
earlier described fold lines 17, 27 and 29 form a plurality of panels in 
the front and side walls and closure flaps. 
Front wall includes panels 40 and 42; side walls 14 each include a panel 
48; front closure flap 20 includes panels 44 and 46; and each side closure 
flap 24 includes panels 50, 52, 54, 56, 58 and 60. 
When it is desired to convert the structure T of FIG. 2 to a shipping 
container SC of FIG. 4 with a bellows closure arrangement, the side 
closure flaps 24 are folded on lines 33 and 33, as shown in FIG. 3, so 
that panels 50, 56-58, and 52-54-60 form the bellows arrangement. 
When it is desired to convert the structure T of FIG. 2 to a display 
structure DC of FIG. 7, side walls and side closure flaps 14 and 24 are 
folded on fold lines 39 and front wall 10 is folded on fold line 35 to 
provide a chair shaped display structure. 
Although the structures are not finally folded on lines 31 or 37, the 
structure can be folded on these lines as an intermediate step in either 
folding sequence. 
Thus, it will be understood that the novel structure of the invention lends 
itself to be used for two different purposes, shipping or displaying, and 
can be readily changed from one form to the other by utilizing the unique 
fold line arrangement to accomplish this purpose.
