Abstract

PROBLEM TO BE SOLVED: To display a commodity in a higher position by securely supporting the commodity in a lifted position.SOLUTION: In the packaging box including a bottom wall 1, a top wall 2, sidewalls 3 and end walls 15 opposite to each other respectively, the top wall 2 and both sidewalls 3 can be divided into the right and left parts. Additionally, both sides of the bottom wall 1 are provided with valley fold lines 11 extending in front-and-rear direction, and mountain fold lines 12 extending parallel to each other at the side of the corresponding end walls 15. When the box is used for a display, the top wall 2 and both sidewalls 3 are divided into right and left parts. As the bottom wall 1 is folded along the valley fold lines 11 and mountain fold lines 12, each leg 16 formed from a part extending sidewise from the corresponding mountain fold line 12 is vertically rotated together with a receiving plate part 17 sandwiched between the valley fold lines 11 and mountain fold lines 12 of the bottom wall 1, and the receiving plate parts 17 are folded back, thereby a placing part 18 sandwiched between the valley fold lines 11 of the bottom wall 1 is supported in a lifted state by the legs 16 to be placed on the receiving plate parts 17. Even if the folds along the valley and mountain folding lines 11 and 12 are liable to return by repulsion, the repulsing force acts in the direction in which the placing part 18 is further moved upward. Accordingly, a rotating force is not applied to the legs 16.

Description

  The present invention relates to a packaging box that can support and display a product in a lifted state.

  Conventionally, as a packaging box suitable for food cooking in a microwave oven, the following Patent Document 1 describes such a packaging box as shown in FIGS.

  The packaging box includes an inner tray 51 for loading food and an outer box 52 for storing the food. The outer box 52 includes a bottom wall 53, a top wall 54, a longitudinal side wall 55 and an end in the width direction that face each other. A cut line 57 that is formed from the wall 56 and has a connecting portion at substantially the center of the top wall 54 is provided, and a cutout portion 58 that extends downward with the cut line 57 as a vertex is formed on both side walls 55. A valley fold line 59 extending in the width direction from the lower end of the notch 58 is provided.

  When cooking food contained in the inner tray 51 of such a packaging box with a microwave oven, the connecting portion of the cut line 57 is cut, the top wall 54 is divided, and the folding along the valley fold line 59 is accompanied. When the leg portion 60 composed of the side portion of the mountain fold line 59 is rotated to the vertical position, the inner tray 51 is supported in the lifted state, so that the microwave of the microwave oven is also included from below the inner tray 51. The food is evenly irradiated and the food is evenly heated.

  However, when the packaging box as described above is used to make a product displayed at a store stand out, when the product is sequentially extracted from the inner tray 51 and the load is reduced, the folding at the valley fold line 59 rebounds. The lifting state of the inner tray 51 may not be maintained.

  Therefore, an object of the present invention is to ensure that a product is supported in a lifted state and can be displayed at a high position.

  In order to solve the above problems, the present invention is a packaging box comprising a bottom wall, a top wall, opposing side walls and end walls, respectively, and the top wall and both side walls can be divided into left and right sides, and on both sides of the bottom wall, A valley fold line extending in the front-rear direction and a mountain fold line parallel to the end wall side are provided, and when changing to the exhibition state, the top wall and both side walls are divided, and the bottom wall is folded along the valley fold line and the mountain fold line. Rotate the leg part that consists of the side part from the mountain fold line to the vertical position together with the valley fold line of the bottom wall and the receiving plate part sandwiched between the mountain fold lines, and when the receiving plate part is folded back, it becomes the valley fold line of the bottom wall The sandwiched mounting portion is supported by the leg portion so as to be placed on the receiving plate portion.

  In addition, a ceiling line is provided on the top wall and two side cutting lines are provided on the side wall with a space therebetween, and the top wall and both side walls can be divided into left and right in accordance with the cutting.

  Further, the two side cut lines of the side wall are inclined so that the interval is widened downward, and with the folding back of the receiving plate part, the mounting part is more than the upper end of the top wall forming the outer part of the leg part. I tried to go down.

  In this packaging box, even if the folding at the valley fold line and the mountain fold line is rebounded in a state where the placing part on which the product is placed is lifted by the leg body part, the repulsive force further raises the placing part. Since no rotational force is generated in the leg portion, the product can be reliably supported in a lifted state and displayed at a high position, and an excellent appeal effect can be obtained.

  In addition, as the receiving plate portion is folded, the placing portion is lowered from the upper end of the top wall forming the outer portion of the leg portion, and the product is supported from the outside by the top wall, thereby It is possible to prevent the product from falling.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  This packaging box with a lifting support function is a wrap-round cardboard box that collects and packages commodities such as small boxes of confectionery and is formed from a blank as shown in FIG. In this blank, the long side of the bottom wall 1, the top wall 2, the pair of side walls 3, and the passage piece 4 are connected in a row so as to form a square tube during assembly, and the inner ends are formed on both short sides of the side wall 3. An outer end plate 6 is connected to both the short sides of the bottom wall 1 and the top wall 2 of the plate 5.

  The ceiling wall 2 is provided with two parallel ceiling lines 7 extending across the side walls 3, and each side wall 3 is inclined so as to have a gap extending downward from the ceiling line 7 at the time of assembly. Two side cutting lines 8 are provided. Moreover, the side cut line 8 is provided also in the passage piece 4 so that the side cut line 8 of the side wall 3 may overlap. At the boundary between the bottom wall 1, the side wall 3 and the passage piece 4, a bottom cutting line 9 extending inward is provided following the side cutting line 8.

  Further, a horizontal cutting line 10 is provided in the middle part of each side wall 3, extending along the two side cutting lines 8, with the central part bulging in an arc shape toward the top wall 2 side.

  The top cutting line 7, the side cutting line 8, the bottom cutting line 9, and the horizontal cutting line 10 are perforated cut lines in which cuts and connecting portions are alternately interrupted, and are cut when the connecting portions are broken.

  On both sides of the bottom wall 1, a valley fold line 11 extending in the width direction and a mountain fold line 12 extending in the width direction on the outer end plate 6 side are provided following the inner end of the bottom cut line 9. The valley fold line 11 is a ruled line entered from the front side of the cardboard, and the mountain fold line 12 is a lead ruled line between the ruled line entered from the back side of the cardboard and the cut line.

  The valley fold line 11 exists only in a portion near the boundary between the side wall 3 and the passage piece 4 of the bottom wall 1, and a U-shaped projecting outward is projected on a portion sandwiched between the valley fold lines 11 on the same line. A cut line 13 is provided. The mounting line 13 is a perforated cut line in which cuts and connecting portions are alternately interrupted.

  In the passage piece 4, an auxiliary ruled line 14 is provided on the extension line of the valley fold line 11 with a cut in order to allow bending when changing to the display state.

  When assembling such blanks and packaging products such as confectionery, as shown in FIG. 2, the bottom wall 1, the top wall 2 and the pair of side walls 3 are folded into a rectangular tube shape and the product is wrapped. Then, the passage piece 4 is affixed to the inner surface of the side wall 3 on the opposite side, and the inner end plate 5 and the outer end plate 6 are sequentially bent and bonded together to form a pair of end walls 15 and sealed.

  On the other hand, when the product packaged in this way is delivered to a retail store and is switched from the packaged state shown in FIG. 2 and FIG. As shown in FIG. 3, the horizontal cutting line 10 is cut, the portion directly above the horizontal cutting line 10 is lifted, the two side cutting lines 8 and the ceiling cutting line 7 above the horizontal cutting line 10 are cut, and the ceiling cutting line 7 and The strip-shaped portion sandwiched between the side cut lines 8 is cut off, and the top wall 2 and the side walls 3 are divided into left and right.

  Next, as shown in FIG. 4 and FIG. 6B, after cutting the two side cut lines 8 below the transverse cut line 10 on the side wall 3, the bottom cut line 9 is cut, and the valley fold line 11 is pivoted. As described above, the leg portion 16 composed of the side portion of the mountain fold line 12 is rotated in the vertical direction together with the valley fold line 11 and the receiving plate portion 17 sandwiched between the mountain fold line 12.

  Then, as shown in FIG. 6 (c), from the state where the leg portion 16 and the receiving plate portion 17 stand upright, as shown in FIGS. 5 and 6 (d), the valley fold line 11 and the mountain fold line 12 conflict. When the receiving plate portion 17 is folded back along with the bending in the direction, the placing portion 18 sandwiched between the valley fold lines 11 is supported in the lifted state by the leg portion 16 so as to be placed on the receiving plate portion 17.

  At this time, since the part between the valley fold lines 11 projects to the left and right according to the shape of the mounting line 13, the product G is stably supported in the left and right direction. In addition, the remaining portions of the side wall 3 connected to the front and back of the placement portion 18 are held in an upright state when they are along the inner side of the side wall 3 of the leg portion 16 while bending both end portions thereof.

  In the packaging box as described above, the product G is sequentially extracted in a state where the placing portion 18 on which the product G is placed is lifted by the leg body portion 16 and the load is reduced, and the folding at the valley fold line 11 and the mountain fold line 12 is performed. Even if it tries to return due to repulsion, the repulsive force acts in a direction that further raises the mounting portion 18, and no rotational force is generated in the leg portion 16, so that the leg portion 16 is stabilized in an upright state.

  For this reason, the product G can be reliably supported in the lifted state and can be displayed at a position higher than the fall prevention wall of the storefront fixture, and the product G can be made conspicuous and an excellent appeal effect can be obtained.

  Further, as the receiving plate portion 17 is folded back, the placing portion 18 is lowered from the upper end of the top wall 2 that forms the outer portion of the leg body portion 16, so that the product G is supported from the outside by the top wall 2, The product G can be prevented from falling sideways from the placement unit 18, and the product G can also be prevented from falling in the front-rear direction by the remaining portion of the side wall 3 rising from the front and back of the placement unit 18. it can.

  Furthermore, since the leg part 16 is connected via the mounting part 18, the conversion operation from the packaging state to the display state can be easily performed, and one blank having the same outline as a normal packaging box Therefore, the amount of cardboard used does not increase, and the packaging cost can be reduced.

  In the above embodiment, two ceiling lines 7 are exemplified, but in a packaging box having a small longitudinal dimension, only one ceiling line 7 may be provided.

  Moreover, although the top cutting line 7, the side cutting line 8, the bottom cutting line 9, and the horizontal cutting line 10 are illustrated as perforated cut lines, the top wall 2, the side wall 3 and its ridges, the side wall 3 and the bottom wall 1 are illustrated. Alternatively, the ridges and the like may be partially punched to provide through windows, and cutting may be continued through the through windows.

  Further, although a wrap round type cardboard box has been illustrated, a lifting support function can be imparted by a similar configuration also in a grooving cardboard box, a tack end carton, or the like.
