Description

  The present invention relates to a modified packaging box that can be used as a square box or a triangular box depending on the amount and shape of contents.

  For example, in mail order merchandise delivery, etc., as shown in FIG. 4 (a), it is composed of a blank in which side plates 51, 52, 53, and 54 that form a peripheral wall are connected, and both side edges are joined and separated. A rectangular box shape covering the end face with a rectangular lid member 55 and the side plates 51 and 54 on both sides are superposed and fixed as shown in FIG. 4B, and a separate triangular lid member 56 is placed on the end face. A packaging box that can be transformed into a triangular box shape is used.

  However, in the packaging box as described above, it is necessary to prepare two types of lid members, and the amount of adhesive tape used for fixing the lid members is large, which requires packaging materials procurement costs and management efforts. Also, there is a problem that the packing workability is not so good.

  Therefore, an object of the present invention is to provide a modified packaging box that can reduce the labor and cost of procurement and management of packaging materials and is excellent in packaging workability.

  In order to solve the above-mentioned problems, the present invention comprises a blank box in which side plates forming a peripheral wall are continuously provided, and a rectangular box shape in which both side edges are joined to close the end surfaces, and both side plates are overlapped to form end surfaces. In a packaging box that can be transformed into a closed triangular box shape, a lid member in which a rectangular lid plate and an insertion piece are sequentially provided is extended from the side plate, and a score line is formed at the boundary between the lid plate of the lid member and the insertion piece. Insert a crease line in an oblique direction from the base end side of the lid member toward the center side of the cut line, and in the square box form, close the lid plate in a square shape and insert the insertion piece along the inner surface of the peripheral wall. In the insertion and triangle box form, the tip side part is cut off from the cut line of the lid member, the lid plate is bent along the crease line, the triangular lid plate is closed, and the insertion formed on the tip side of the crease line The part was inserted along the inner surface of the peripheral wall.

  In this modified packaging box, the side plate forming the peripheral wall and the lid member are integrated, and the lid member is used in both the square box form and the triangular box form. There is no need to manage inventory.

  Further, since it is not necessary to stick the base end of the lid member to the side plate at the time of sealing, the amount of adhesive tape used can be reduced, and the labor and cost required for the procurement and management of packaging materials can be reduced.

  In addition, in the square box form as well as in the triangular box form, the end face can be easily closed and sealed by inserting the insertion piece or the insertion part at the tip of the cover plate along the inner surface of the peripheral wall, The assembled shape can be securely held.

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

  This modified packaging box is formed from a single cardboard blank as shown in FIG. In this blank, the rectangular side plates 1, 2, 3, and 4 that form the peripheral wall are successively connected via a ruled line having a long side, and a lid member is provided at both ends of the side plate 1 via a ruled line having a short side. 5 is continuously provided.

  The lid member 5 is sequentially provided with a lid plate 6 and an insertion piece 7 from the side plate 1 side, and the lid plate 6 has a square shape whose one side is slightly longer than the short side of the side plate 1. ing.

  A perforated cut line 8 is formed at the boundary between the cover plate 6 and the insertion piece 7, and an intermediate portion thereof is cut into the cover plate 6 in a V shape, and both ends are formed at the corners of the cover plate 6. Crossing diagonally. On the cover plate 6, a crease line 9 made of two ridges is put in an oblique direction from both sides of the base end of the cover member 5 to the center side of the cut line 8.

  Further, along the front end of the lid plate 6 and one of the crease lines 9, locking projections 10a and 10b are provided by making U-shaped cuts, respectively. A locking recess 11 is provided at each end edge of the side plate 3 by a notch.

  Now, to assemble the blank of FIG. 1 into a rectangular box and pack the product, as shown in FIG. 2 (a), the side plates 1, 2, 3, and 4 are bent to form a square cylindrical peripheral wall, The side edges of the side plates 1 and 4 are joined with an adhesive tape.

  Then, as shown in FIG. 2 (b), the lid plate 6 is closed in a square shape, the insertion piece 7 is inserted along the inner surface of the peripheral wall, and an adhesive tape is applied across the lid plate 6 and the side plate 3. Seal it.

  When sealed in this way, the engagement between the locking projection 10a and the locking recess 11 prevents the peripheral wall and the lid member 5 from being displaced from each other and the cover plate 6 from entering, and the assembled shape is firmly held.

  Moreover, when opening, the cover tape 6 can be easily opened by peeling off the adhesive tape and placing a finger on the locking projection 10a.

  On the other hand, in order to assemble the blank of FIG. 1 into a triangular box and pack the product, as shown in FIG. 3A, the side plates 1, 2, 3, 4 are folded so that the side plates 1, 4 on both sides overlap. Then, a triangular cylindrical peripheral wall is formed, and an adhesive tape is attached to the ridges of the side plates 2 and 4, so that the side plates 1 and 4 are fixed in an overlapped state.

  Then, the front end portion of the lid member 5 is cut away from the cut line 8, the lid plate 6 is bent along the crease line 9, and the triangular lid plate 6 is closed and folded as shown in FIG. The insertion part 6a formed on the front end side of the line of sight 9 is inserted along the inner surface of the peripheral wall, and an adhesive tape is stuck between the lid plate 6 and the side plates 2 and 3 and sealed.

  At this time, along with the cutting along the score line 8, the insertion portion 6a has a tapered shape that is easy to insert, and can be easily sealed.

  When sealed in this manner, the engagement between the locking projection 10b and the locking recess 11 prevents the peripheral wall and the lid member 5 from being displaced from each other and the cover plate 6 from entering, and the assembled shape is firmly held. .

  Moreover, when opening, the cover tape 6 can be easily opened by removing the adhesive tape and placing a finger on the locking projection 10b.

  In the packaging box as described above, the side plates 1, 2, 3, 4 and the lid member 5 forming the peripheral wall are integrated, and the lid member 5 is used in both a square box shape and a triangular box shape. There is no need to procure two types of lid members and manage their stock like the conventional one described above.

  Moreover, since it is not necessary to stick the base end of the cover member 5 to the side plate 1 at the time of sealing, the amount of adhesive tape used can be reduced, and the labor and cost required for procurement and management of packaging materials can be reduced.

  Moreover, in both the rectangular box form and the triangular box form, the end face can be easily closed and sealed by inserting the insertion piece 7 or the insertion part 6a at the tip of the cover plate 6 along the inner surface of the peripheral wall. Therefore, the assembled shape can be securely held.

  Then, by appropriately selecting a square box shape and a triangular box shape according to the quantity and shape of the product, the wasteful space is not generated in the box as much as possible, and the transportation efficiency at the time of delivery of the product is improved. be able to.

  In the above embodiment, in the triangular box form, the adhesive tape is applied to the ridges of the side plates 2 and 4 to fix the side plates 1 and 4 in an overlapped state. The side plates 1 and 4 may be engaged by means such as inserting the insertion piece provided in the slit into a slit provided at the base of the side plate 1.

  In addition, one of the two crease lines 9 put in the lid member 5 is changed to the crease line 9 to be a crease line, and in the triangular box form, by cutting the tip side portion, the insertion portion 6a is Even if it is formed only on one side of the cover plate 6, it can be sealed.
