Description

  The present invention relates to a display / cardboard box sheet and a display / cardboard box.

  A cardboard box for transporting goods is used as a container for collectively storing a plurality of goods from transportation of goods to display. Such a cardboard box for transporting goods is opened after transport, and the packaged goods are taken out from the cardboard box. The taken products are displayed on display shelves and cases for sale. In order to simplify the product display work consisting of taking out the products from the cardboard boxes and displaying them on the shelves and cases, the cardboard boxes in which the products are packed can be used as they are as display cases (hereinafter referred to as cardboard boxes) Have been proposed (see Japanese Patent Application Laid-Open No. 2004-83096).

  This conventional corrugated cardboard box has a square cylindrical part having a front plate and a rear plate facing each other, and a pair of side plates connected to the front plate and the rear plate, and a plurality of units connected up and down from the square cylindrical unit. And has a flap. The corrugated cardboard box includes an opening break guide wire that can be opened from a packaged state to a display state, and the break guide wire is formed on the front plate and the pair of side plates. Specifically, the break guide line is formed horizontally on the front plate, and is formed on a straight line that is inclined upward toward the rear in each side plate. The end point of the side plate is located at the upper edge of the side plate.

  In the conventional cardboard box, a notch is formed in the flap constituting the upper wall along an imaginary line connecting the end points of the side-face plates of the opening breaking guide line. And a packaging state is obtained by affixing the packaging tape so as to seal the notch. Moreover, after making it open from the said packaging state by breaking along the said breaking guide line for opening, the said packaging tape is used as a hinge part, an upper display shelf (a part above the opening breaking guide line ( By rotating the upper part of the front plate, the front and upper parts of the side plate, and the front part of the upper flap) to the upper and rear sides, a display shelf is also formed on the upper part.

  However, in the cardboard box described in the above publication, since the packaging tape is used as a hinge portion, the upper display shelf is rotated when the packaging tape is applied to the side plate. Can not be. For this reason, it is necessary to apply the packaging tape only to the flaps constituting the upper wall. However, if the packaging tape is not attached to the side plate but only to the flaps constituting the upper wall, a sufficient packaging state is obtained. May not be obtained.

  Further, the packaging tape is attached only to the front liner of the upper flap in the upper flap separated by the notch. For this reason, when the upper display shelf is rotated at the hinge (packaging tape), an excessive force acts on the front liner of the upper flap from the packaging tape, causing damage to the front liner, resulting in a display effect. There is a risk of damage.

Here, when the upper display shelf is rotated, the upper inner flap 8 breaks along the second foldable portion 12 and the upper outer flap 7 moves along the first foldable portion 11 when the cardboard box 1 is rotated. The back liner is broken, the front liner of the upper outer flap 7 remains, and this front liner functions as a hinge portion. Thus, since the front liner remains and other parts are broken when the easy-to-bend portion is rotated, the upper display shelf can be easily rotated. Furthermore, the front liner is not affixed with a packaging tape as a hinge portion unlike conventional cardboard boxes, and is not easily damaged by excessive force from the packaging tape, and easily remains with the remaining front liner. In addition, the display effect can be surely achieved.

  In addition, after the display as described above, when the number of displayed products decreases, the upper wall 24 can be removed as shown in FIG. The display and cardboard box can be placed in the separated tray state. For this reason, the display effect by the display and cardboard box can be changed according to the number of products.
