Oct. 16, 1962 T. G. MAIRS DISPLAY PANEL SUPPORTS Filed Aug. 17, 1960 m m M Ba 5' Thomas 6. Mai/as BY gwmam- Af-gw rates This invention relates to an improvement in display panel supports and deals particularly with a simple means of holding a display panel in upright position.

Many displays are formed by leaving certain of the panels of a rectangular container connected and folding them down along diagonal fold lines during shipment. Thus the display forms the container for the shipment of the goods to be displayed. When the container is opened, the display panel, together with the adjacent panels which act as Supporting panels, are folded into upright form to form the display. Normally, the inside surface of the container is printed so that the panels may form an attractive display for the goods contained.

One of the difliculties which has been experienced with displays of this type lies in the fact that after the supporting panels which are designed to support the display panel in upright position have been diagonally folded for a period of time, difficulty is experienced in maintaining them on a common plane. In other words, the supporting panels tend to buckle inwardly, allowing the display panel to incline forwardly. It is the purpose of the present invention to provide a simple and effective means for holding the supporting panels in parallel upright planes, thereby supporting the display panel in a vertical position.

A feature of the present invention resides in the fact that no added attachments are required or no extra paperboard is required in the accomplishment of the result. The entire result is accomplished by the provision of two angular cut lines which may be formed at the time the display is die cut and creased.

A feature of the present invention resides in terminating the diagonal lines of fold in the supporting panels short of the juncture between the supporting panels and the lower panels of the container. An angular cut line extends along the line of fold connecting the supporting panel to the bottom panel for a short distance and then extending upwardly to the end of the diagonal fold line. This angular cut defines a triangular tab which is integral with the portions of the supporting panel above the diagona-l fold line and folds in conjunction therewith. Accordingly, the cut lines do not interfere with the folding of the supporting panels into horizontal position. However, when the supporting panels are folded into upright position, and the generally triangular tabs are forced back into position, the tendency for the supporting panels to collapse inwardly is entirely lost.

These and other objects and novel features of the present invention will be more clearly and fully set forth in the following specification and claims.

In the drawings forming a part of the specification:

FIGURE 1 is a perspective View of the display container in closed position.

FIGURE 2 is a perspective view of the display container in open position.

FIGURE 3 is a sectional view through the container, the position of the section being indicated by the line 33 of FIGURE 1.

FIGURE 4 is a perspective view of the upper portion of the container in partially folded condition.

FIGURE 5 is a diagrammatic view of the blank from which the display container is formed.

While the present structure has been described as a display container, it is obvious that the same principle atent Patented Oct. 16, 1962' can be used in conjunction with any pair of panels hav-v ing flaps foldably connected to an end which is designed to fold from horizontal position to upright position. One of the most common uses of such a structure however, is in a display container, and it is for this reason that the arrangement is shown as such.

The blank for forming the display container A is shown in FIGURE of the drawings as including a front panel 10, a side wall panel 11, a rear wall panel 12, and a side wall panel 13 which are foldably connected along parallel lines of fold 14, 15 and 16. A glue or stitch flap 17 may be connected to one end panel of the series, such as the panel 13, by a fold line 19. Alternatively, the flaps 17 may be omitted and the walls secured in tubular relation by tape.

Bottom closure flaps 20, 21, 22 and 23 are foldably hinged to the lower ends of the panels 10, 11, 12 and 13 respectively along the line of fold 24. In the arrangement illustrated, these bottom closing flaps fold into edge abutting relation as the display is shown as being square in cross section.

A panel 25 is hingedly connected to the top of the front wall panel 10 along a fold line 26. A display panel 27 is hingedly connected to the rear wall panel 12 along a continuation of the same fold line 26. Supporting panels 29 and 30 are hingedly connected to the upper edges of the side wall panels 11 and 13 respectively along this fold line 26. Diagonal fold lines 31 and 32 extend partially across the panels 29 and 30 respectively, these diagonal fold lines normally being at substantially 45 degrees from the fold line 26 so that the parts of the panels 29' and 30 on opposite sides of the diagonal fold lines may fold into face contact. The diagonal fold line 31 is directed toward the juncture between the fold lines 26 and 15 while the fold line 32 is directed toward the intersection between the fold lines 26 and 16.

Angular cut lines are provided in the panels 29 and 30, these out lines forming the basis of the present invention. The out line in the panel 29 includes a portion 33 which extends along the fold line 26 for a short distance and is angled to provide a portion 34 which is at right angles to the cut line portion 33- and which extends to the inner end of the diagonal fold line 31. The cut line portions 33 and 34 form a triangular projection connected to the upper portion 35 of the panel 29 between the diagonal fold line 31 and the fold line 15. The cut lines in the panel 30 include a portion 36 which extends along the fold line 26 fora short distance, and a generally right angular portion 37 which extends generally parallel to the fold line 16 to the end of the diagonal fold line 32. The cut line portions 36 and 37 form a generally triangular projection attached to the upper portion 39 of the panel 30 which lies between the diagonal fold line 30 and the fold line 16.

In use, the container is secured in fiat tubular form by securing the manufacturers joint in any suitable manner. When used, the bottom closing flaps are folded into right angular relation to the panels to which they are hinged and are adhered in this position. In closing the upper portion of the container, the lower portions 40 and 41 of the side wall flanges 29 and 30 are folded inwardly and downwardly and the display panel 27 is simultaneous- 'ly folded inwardly and downwardly. The upper portions 35 and 39 of the panels 29 and 30 thus fold between the lower portions 40 and 41 of these panels 29 and 30 and the display panels 27. The triangular projections formed by the cut lines remain in the plane of the upper portions 35 and 39 of the panels 29 and 30, as indicated in FIGURES 3 and 4 of the drawings.

If the diagonal fold lines described extend to the corners of the container, as is usual practice, difficulty is experienced in folding the side wall panels 29 and 30 in upright position, as they tend to buckle inwardly toward the position illustrated in FIGURE 4. However, with the present construction, when the triangular projections are forced back into the plane of the side walls 11 and 12, they frictionally engage the portions of the container from which they are cut and these portions hold the side wall or supporting panels 29 and 39 in upright position as indicated in FIGURE 2 of the drawings.

Either the inner surface of the containers may be printed, or both surfaces may if desired so as to provide an attractive display when the case is in open position.

In accordance with the patent statutes, I have described the principles of construction and operation of my improvement in display panel supports, and while I have endeavored to set forth the best embodiment thereof, I desire to have it understood that changes may be made within the scope of the following claims without departing from the spirit of my invention.
