Description

  The present invention relates to an assembling-type packaging box used for sale with confectionery or the like stored therein, and more particularly to a dice-shaped assembling-type packaging box in which eight corners of a cube are replaced with small triangular planes to eliminate corners. .

  There are various forms of packaging boxes that store and sell confectionery for children. As a general one, there is one in which an inner box with an upper surface opening is slidably inserted into a rectangular tube having a square section. Instead of sliding the entire inner box as a slightly modified version, there is one in which one side portion of the inner box is slid and opened obliquely to take out the confectionery and the like inside (see Patent Document 1). ). In addition, there is a case in which an opening / closing opening that can be opened and closed is formed on the upper side of a rectangular parallelepiped paper packaging box without using an inner box (see Patent Document 2). Furthermore, as a slightly larger box that can also be used as a lunch box, there is an assembly-type packaging box that folds and assembles a pair of rectangular packaging plates having the same size (see Patent Document 3).

However, none of these packaging boxes have a rectangular parallelepiped shape with a simple outer shape. For this reason, the packaging box for storing and selling confectionery for children is not attractive for children. Some packaging boxes have animal shapes, mascot shapes, etc. to stimulate children's purchasing minds, but they are attractive, but have the problem of high production costs.

Accordingly, the upper outer cover piece 2 is not easily opened, and the contents opening / closing opening 3 is reliably maintained in a closed state.

  Hereinafter, an embodiment of an assembly-type packaging box according to the present invention will be described with reference to the drawings. FIG. 1 is an external perspective view of an assembly-type packaging box 1 according to the present invention, and FIG. 2 is a perspective view of a state in which an upper cover (upper outer cover piece 2) is opened so that an opening 3 for putting in and out contents can be seen. 3 and 4 are developed plan views of the constituent paper pieces, and FIG. 5 is an exploded perspective view for explaining the assembly method. As shown in FIG. 1, the assembly-type packaging box 1 has a dice shape in which eight corners of a cube are replaced with a small triangular plane (triangular piece 26).

  The assembly-type packaging box 1 is composed of five pieces of continuous paper 4 shown in FIG. 3 formed by punching cardboard of appropriate thickness, and three pieces of paper, a third side piece 5 and a fourth side piece 6 shown in FIG. They are assembled by bending them as shown in FIG. The five continuous pieces 4 are crease lines 11a to 11d in which five pieces of paper, that is, an upper outer cover piece 2, a first side piece 7, a bottom piece 8, a second side piece 9, and an upper inner cover piece 10 are provided at each boundary. Are arranged in a row in this order across the. The upper outer lid piece 2 is a piece of paper that closes the opening 3 provided in the upper inner lid piece 10 located below the upper lid piece 2 as shown in FIG. The bottom piece 8 is a paper piece forming the bottom surface of the assembly-type packaging box 1, and the first side piece 7 and the second side piece 9 are side pieces. The four paper pieces of the first side piece 7, the bottom piece 8, the second side piece 9, and the upper inner lid piece 10 are bent to form a square tube 60 as shown in FIG.

  Each piece of paper constituting the five continuous pieces 4 has a line-symmetric shape with respect to the center line in the continuous direction in the development plan view shown in FIG. The upper surface outer lid piece 2 located at one end has an octagonal shape in which four corners of a regular square are cut into a triangular shape. The length of the small side 20 cut out is equal to the length of the side of the small triangular plane (triangular piece 26) provided at the eight corners of the cube. Out of the remaining four long sides 21 other than the small side 20 in the octagonal shape, the outer lid insertion tongue piece 23 projects from the long side 21 located on the opposite side of the first side piece 7 via the crease line 11e. It is. The outer lid insertion tongue piece 23 is inserted into a later-described fourth cut 24 formed on a crease line 11d at the boundary between the second side piece 9 and the upper inner lid piece 10 during assembly.

  Three paper pieces of the first side piece 7, the bottom piece 8, and the second side piece 9 in the five continuous pieces 4 have the same shape, and an octagon having the same shape as the top cover piece 2 is formed at the center of each piece of paper. It is surrounded by a crease line. Since the three paper pieces have the same shape and are symmetrical with respect to the center line in the continuous direction, the shape of each of the extended paper pieces extended to the peripheral edge thereof is the upper side of the first side piece 7 in FIG. Will be described as an example.

  On the small side 20a of the first side piece 7 on the upper surface outer lid piece 2 side, a regular triangular triangular piece 26a constituting a small triangular plane provided at the eight corners of the cube is extended. A first folding piece 28a extends through a crease line 27a on the right side (side on the upper surface inner lid piece 10 side) of the triangular piece 26a in the protruding direction. The first folding piece 28a extends from the entire length of the crease line 27a in a short band shape in a direction that forms an angle of 45 ° with the upper long side 21a of the first side piece 7a. In the state assembled by forming an angle of 45 ° with the upper long side 21a, the right side (side on the upper surface inner lid piece 10 side) 33a of the first folding piece 28a is the upper side length of the first side piece 7. It will be in the state corresponding to the crease line along the edge | side 21a. Near the tip of the first folding piece 28a, there is provided a first cut 32a extending from the edge of the left side 50a at a right angle in the direction of the right side 33a (toward the center of the first side piece 7).

  A second folding piece 30a extends from the upper long side 21a of the first side piece 7 via a crease line. The second folded piece 30a extends in a strip shape in parallel with the first folded piece 28a from the entire length of the upper long side 21a. Therefore, the second folded piece 30a also extends at an angle of 45 ° with the upper long side 21a. The length of the right side (side on the upper surface inner lid piece 10 side) 30a of the second folded piece 30a is equal to the length of the side of the triangular piece 26a. The front end side 42a at the end in the extending direction of the second folding piece 30a is formed to form an angle of 135 ° with the right side 30a. In the assembled state by being formed in this way, the right side 30a of the second folding piece 30a coincides with the small side 27b of the triangular piece 26b of the bottom piece 8 adjacent to the first side piece 7, and the tip side 42a is in a state where it coincides with the upper long side 21b of the bottom piece 8.

  A second cut 34a parallel to the upper long side 21a is provided from the center of the tip side 42a of the second folded piece 30a. The second cut 34a is engaged with the first cut 32b provided in the first folded piece 28b of the second side piece 9 during assembly. The first cut 32b and the second cut 34a are provided at positions where they can be engaged with each other during assembly. Furthermore, a third cut 35a is formed along the crease line at the center of the crease line along the upper long side 21a of the first side piece 7.

  A third folded piece 36a having a triangular shape smaller than the triangular piece 26a extends through a crease line on the remaining small side 20aa of the first side piece 7 where the triangular piece 26a is not provided.

  The upper inner lid piece 10 located at the other end of the five continuous pieces 4 is also formed in substantially the same shape as the first side piece 7. The difference is that a trapezoidal fourth folding piece 37 is formed on the right long side 44 located on the opposite side of the second side piece 9 via a crease line 11f, and the central portion is used for taking in and out contents. This is a point where a rectangular opening 3 is formed. A trapezoidal opening piece 40 extends from two opposing sides of the rectangular opening 3 via a crease line 38.

  Along the crease line 11d at the boundary between the upper surface inner lid piece 10 and the second side surface piece 9, a fourth cut 24 for inserting an outer lid insertion tongue piece 23 provided on the upper surface outer lid piece 2 at the center thereof. Is formed. A semicircular notch 41 having a diameter shorter than the length of the fourth notch 24 is formed on the second side piece 9 side that is in contact with the fourth notch 24, and the center thereof is the fourth side piece 4. It is located at the center of the cut 24. This notch 41 is for facilitating the drawing of the outer lid insertion tongue piece 23 inserted into the fourth cut 24.

  As shown in FIG. 4, the third side piece 5 and the fourth side piece 6 have an octagonal shape in which four corners of the same square as the upper outer cover piece 2 are cut into a triangular shape. Then, a side piece insertion tongue piece 43 to be inserted into a third cut 35 a provided on a piece of paper other than the upper surface outer cover piece 2 in the five continuous pieces 4 is provided at the center of each side of the regular square before being cut off.

  Next, a method of assembling the assembling-type packaging box 1 using three pieces of paper, that is, the five continuous pieces 4, the third side piece 5, and the fourth side piece 6 will be described with reference to FIG. First, five paper pieces constituting the five continuous pieces 4 are bent at right angles to the inner side of the assembling-type packaging box 1 along the boundary crease lines 11a to 11d. The fourth folding piece 37 of the upper surface inner lid piece 10 is also bent at a right angle in the same direction, and the crease line 11f at the base end is aligned with the crease line 11a at the boundary between the upper surface outer lid piece 2 and the first side piece 7. Next, the upper surface outer cover piece 2 is overlaid on the upper surface inner cover piece 10, and the outer cover insertion tongue piece 23 of the upper surface inner cover piece 10 is bent at a right angle along the crease line 11e of the base end portion to obtain the upper surface inner cover piece. 10 and the 4th notch 24 provided in the boundary of the 2nd side piece 9 is inserted. Thereby, the 5 continuous piece 4 is fixed to a square cylinder shape.

  As the next step, a large number of small paper pieces provided on the four paper pieces other than the upper surface inner cover piece 10 in the five continuous pieces 4 are folded to form the peripheral portions of the left and right openings 46 of the rectangular tube 60. Since the four corner peripheral portions are folded in the same manner, the corner peripheral portion in which the first side piece 7 and the bottom piece 8 form a right angle will be described. First, the triangular piece 26b of the bottom piece 8 overlaps the small triangular third folded piece 36a of the first side piece 7, and the first folded piece 28b extended to the triangular piece 26b It folds so that the 2nd folding piece 30a of 1 side piece 7 may overlap. And the 1st cut 32b provided in the 1st folding piece 28b of the bottom face piece 8 and the 2nd cut 34a provided in the 2nd folding piece 30a of the 1st side piece 7 are mutually engaged. . At that time, the base end portion of the second folded piece 30b of the bottom piece 8 is folded so as to hold the engagement from above. Such folding is performed at the left and right corner peripheral portions. As a result, a rectangular tube 60 is formed in which the peripheral edge portions are formed by folding the left and right openings 46 as shown in the center portion of FIG. The square tube 60 is firmly fixed by the engagement of the first cut 32b and the second cut 34a, and is not broken even when the upper outer cover piece 2 is opened upward as shown in the figure.

  Next, each of the four side piece insertion tongue pieces 43 of the third side piece 5 and the fourth side piece 6 is bent at a right angle, and the first side piece 7, the bottom piece 8, the second side piece 9, and the upper inner lid piece. 10 is inserted into the third cuts 35a to 35d provided in the left and right openings 10 to close the left and right openings 46 of the rectangular tube 60. As described above, the dice-shaped assembly-type packaging box 1 is completed in which the eight corners of the cube shown in FIGS. 1 and 2 are replaced with a small triangular plane (triangular piece 26).

  The assembly-type packaging box 1 having such a configuration can be assembled in a short time without using an adhesive by using only three pieces of paper, that is, the five continuous pieces 4, the third side piece 5, and the fourth side piece 6. This has the advantage that the manufacturing cost is reduced. Since it is plate-shaped before assembly, transportation fare and storage space can be reduced. Since the eight corners of the cube have been replaced with small triangle planes, the corners will not break even if dropped or rolled. Since the appearance is a dice shape, it is more attractive than a simple cube and can be rolled to play, so it is suitable as a packaging box for selling candy for children. In addition, a large number of items can be stacked at a high density.
