Description

  The present invention relates to a packaging box for packing products and the like, and more particularly, to a packaging box having a configuration for determining whether it is opened or unopened.

  Conventionally, as a packaging box used when packing and shipping a packaged item such as a small electrical product, a precision device main body, or a replacement part, the upper lid and the inner lid are configured to overlap each other at the opening. Packaging boxes are widely used.

  In recent years, reducing the environmental impact of industrial waste has become an important issue, and replacement parts such as toner cartridges mounted on image forming apparatuses must be collected for recycling use. Has occurred. At this time, if the used replacement parts are repackaged and returned to the packaging box in which the new replacement parts were packed, the replacement parts can be easily played without rattling because the packaging material designed for the shape of the replacement parts is used. The packaging box can be reused.

  However, if the packaging box is reused, when the user or service person stores the replacement part, the packaging box containing the used replacement part and the packaging box containing the new replacement part must be placed in the same place. In this case, since the appearance of the packaging box is the same, there is a problem that it is impossible to determine whether the contents are used or new unless the packaging box is opened.

  Therefore, a method for easily determining whether the packaging box is unopened or has been opened has been proposed. For example, Patent Document 1 discloses cutting and opening zipper, perforation, tape, etc. on the flap of the packaging box. There is disclosed a cartridge packaging box including a portion, a resealing insertion tongue piece, and an insertion opening for inserting the insertion tongue piece. Moreover, in patent document 2, it overlaps with the 2nd wall part except the 1st wall part which is connected with the lid wall connected with the 1st wall part which comprises the surrounding wall of a packaging box, and the cover wall. An adhering wall, and an adhering wall adhered to the outer surface of the third wall portion excluding the first and second wall portions is connected to the lid wall, and the adhering wall has a first breaking line. There is disclosed a packaging box provided with a protruding piece portion surrounded by a lid wall.

  However, since the method of Patent Document 1 breaks and opens a part of the packaging box, there is a problem in that dust such as a packaging box or a piece of tape is generated. Moreover, in the method of patent document 2, since a sticking wall is glued at the time of product packing, facilities, such as the process of apply | coating glue (adhesive) to a packaging box, and a gluing apparatus, are needed, and a number of members and a manufacturing man-hour increase. This will increase the cost of the packaging box.

  In view of the above-described problems, the present invention provides a packaging box having a simple configuration that does not require gluing at the time of packaging, can clearly see whether it has been opened, and does not generate dust or the like at the time of opening. Objective.

  In order to achieve the above object, the present invention is composed of a bottom surface and side plates erected on the four sides of the bottom surface, the box having an open top surface, and a folding line on one side of the opening edge of the box. An upper lid that is continuously provided, an inner lid that is connected to a side of the opening edge of the box that faces the side on which the upper lid is extended, via a fold line, and that overlaps the inner side of the upper lid, and the box A lid flap that is connected to a side adjacent to the side where the upper lid extends among the opening edge of the body via a fold line, and that is formed by bending the top end of the upper lid and a lid flap that overlaps the inside of the upper lid And a first insertion hole that is formed along a boundary between the inner lid and the side plate to which the inner lid is provided, and into which the insertion piece is inserted. Tongue shape surrounded by a cut line having a convex shape and a folding line connecting both ends of the cut line In the inner lid or the lid flap, a slit is formed at a position facing the folding line, and the tongue-like piece is bent along the folding line when the box is assembled. The packaging box is characterized in that the upper lid and the inner lid are held in a closed state by being inserted into the slit and inserting the insertion piece into the first insertion hole.

  According to the present invention, in the packaging box configured as described above, a mark indicating that the upper lid has been opened is formed on the surface of the tongue-like piece.

  Further, the present invention provides a packaging box having the above-described configuration, wherein the tongue-shaped piece is formed on the upper lid by bending the tongue-shaped piece when the upper lid and the inner lid are held closed with the tongue-shaped piece inserted into the slit. A mark indicating that the upper lid is unopened is formed on the surface of the inner lid or the lid flap exposed from the formed through hole.

  According to the present invention, in the packaging box configured as described above, the tongue-like piece has a tapered shape that gradually becomes narrower toward a tip portion inserted into the slit.

  According to the present invention, in the packaging box having the above-described configuration, a lid plate fixing piece that extends across the first insertion hole and reaches the inner lid is formed on the side plate on which the inner lid is connected. A second insertion hole into which the lid plate fixing piece is inserted is formed at the boundary between the insertion piece and the insertion piece.

  According to the 1st structure of this invention, in the state which the assembly of the packaging box was completed, the tongue-shaped piece formed in the upper cover was inserted in the slit in the folded state. Then, after the upper lid is once opened, the folded tongue-like piece is extended along the upper lid without being inserted into the slit when repacking. Thereby, it is possible to confirm at a glance whether or not the packaging box has been opened, and the packaging box has a simple configuration that does not require gluing and does not generate dust when opened.

  Moreover, according to the 2nd structure of this invention, in the packaging box of the said 1st structure, a tongue-shaped piece is formed by forming the mark which shows that the upper cover has been opened on the surface of the tongue-shaped piece. In the folded state, the mark is not visible, and the mark is visible when the tongue-shaped piece is extended along the upper lid. Therefore, the user can know at a glance whether or not the packaging box has been opened even for a user who does not know that the tongue-shaped piece is bent and the tongue-shaped piece is unopened. It becomes a checkable packaging box.

  According to the third configuration of the present invention, in the packaging box having the first or second configuration, when the upper lid and the inner lid are held in a closed state with the tongue-like piece inserted into the slit, When the tongue-like piece is folded, a mark is formed on the surface of the inner lid or lid flap exposed from the through-hole formed in the upper lid by bending the piece so that the upper piece is unopened. Is visible, and when the tongue-shaped piece is extended along the upper lid, the mark becomes invisible. Therefore, the user can know at a glance whether or not the packaging box has been opened even for a user who does not know that the tongue-shaped piece is bent and the tongue-shaped piece is unopened. It becomes a checkable packaging box.

The elements on larger scale of the periphery of the tongue-like piece 23 of the upper cover 9 in the state repacked using the packaging box 100 of 2nd Embodiment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an exploded view of a packaging box 100 according to the first embodiment of the present invention. In addition, in FIG. 1, a mountain fold line is displayed with a broken line. Further, the horizontal direction (horizontal direction of the packaging box 100) in FIG. 1 is referred to as an X-axis direction, and the vertical direction (vertical direction of the packaging box 100) is referred to as a Y-axis direction.

  The packaging box 100 is formed of a single sheet material such as corrugated cardboard, and is folded into four side plates 1, 2, 3, 4 connected in series via a fold line and to the lower side of the side plates 1, 3 On the bottom plates 5 and 6 connected through the bottom plate, bottom flaps 7 and 8 connected to the lower sides of the side plates 2 and 4 through the fold line, the top lid 9 connected to the upper side of the side plate 1 through the fold line, and the upper side of the side plate 3 The inner lid 10 is connected via a folding line, and the lid flaps 11 and 12 are connected to the upper sides of the side plates 2 and 4 via a folding line. The side plate 1 and the side plate 3 and the side plate 2 and the side plate 4 are formed so that the lengths in the X-axis direction are equal to each other. An adhesive piece 1a is connected to the edge of the side plate 1 via a fold line.

  An insertion piece 9a is connected to the side of the upper lid 9 facing the side plate 1 via a fold line, and the inner lid 10 has a boundary between the side plate 3 and the inner lid 10 (opening / closing support line of the inner lid 10). A first insertion hole 13 into which the insertion piece 9a is inserted is formed. The length of the first insertion hole 13 in the X-axis direction is longer than the length of the insertion piece 9a in the X-axis direction so that the insertion piece 9a can be inserted.

  Further, the side plate 3 is formed with a lid plate fixing piece 15 that crosses the first insertion hole 13 and reaches the inner lid 10, and the insertion piece 9a has a boundary between the upper lid 9 and the insertion piece 9a (the insertion piece 9a A second insertion hole 17 into which the cover plate fixing piece 15 is inserted is formed at substantially the center of the fold line. The length of the second insertion hole 17 in the X-axis direction is longer than the length of the lid plate fixing piece 15 in the X axis direction so that the lid plate fixing piece 15 can be inserted.

  A cut line 20 is formed in a substantially central portion of the upper lid 9. The cut line 20 is formed in a convex shape in plan view toward the insertion piece 9 a, and both ends of the cut line 20 are connected by a folding line 21. A substantially pentagonal region surrounded by the cut line 20 and the folding line 21 is cut and raised along the cut line 20 to form a tongue-like piece 23. On the surface of the tongue-like piece 23, characters “opened” (see FIG. 4) are printed. The folding line 21 can be formed by a crease line, a perforation, a half cut line, or the like. Further, the inner lid 10 is formed with a slit 25 at a location facing the folding line 21 when the upper lid 9 is overlapped. The slit 25 has a minimum width into which the tongue-like piece 23 can be inserted.

  Next, the assembly procedure of the packaging box 100 of this invention is demonstrated. First, after folding the fold line between the side plates 1 to 4, the adhesive piece 1 a is bonded to the inside of the side plate 4 to form the body portion of the packaging box 100. Then, the bottom plates 5 and 6 and the bottom flaps 7 and 8 connected to the lower sides of the side plates 1 to 4 are bent inward to engage the protrusions of the bottom plate 6 and the bottom flaps 7 and 8 with the recesses 5a of the bottom plate 5, The bottom surface of the packaging box 100 is formed. Thereby, as shown in FIG. 2, a box 30 having a rectangular shape in plan view and having an opening 31 at the upper end surrounded by the bottom surface and the side plates 1 to 4 is formed.

  Next, after a replacement part (for example, a toner cartridge), which is an object to be packed, is stored in the box 30 from the opening 31, the lid flaps 11, 12, the inner lid 10, and the upper lid 9 are arranged in this order along the fold line. The box 30 is bent inside. FIG. 3 shows a state in which the lid flaps 11 and 12, the inner lid 10 and the upper lid 9 are bent.

  Next, as shown in FIG. 4, the portion surrounded by the cut line 20 and the folding line 21 of the upper lid 9 is pressed with a finger to cut the tongue-like piece 23 inward. Then, the tip of the tongue-like piece 23 is inserted into the slit 25 of the inner lid 10. Since the tongue-like piece 23 has a tapered shape gradually becoming narrower toward the tip end portion inserted into the slit 25, it can be smoothly inserted into the slit 25.

  Then, as shown in FIG. 5, the insertion piece 9 a of the upper lid 9 is inserted into the first insertion hole 13 provided in the inner lid 10. Finally, the assembly of the packaging box 100 is completed by inserting the cover plate fixing piece 15 of the side plate 3 into the second insertion hole 17 of the insertion piece 9a. In this state, since the tongue-like piece 23 is inserted into the slit 25, the characters “opened” printed on the tongue-like piece 23 cannot be visually recognized.

  When repacking used replacement parts in the packaging box 100, after the replacement parts are stored in the box 30 from the opening 31, the lid flaps 11, 12, the inner lid 10 and the upper lid 9 are folded in this order. Bend along the line to the inside of the box 30. At this time, since the tongue-like piece 23 tries to return from the bent state by the restoring force of the sheet material, the tongue-like piece 23 overlaps the surface of the inner lid 10 without being inserted into the slit 25 as shown in FIG. As a result, the tongue-like piece 23 is sandwiched between the upper lid 9 and the inner lid 10 and the bent state is extended.

  Then, the insertion piece 9a of the upper lid 9 is inserted into the first insertion hole 13 provided in the inner lid 10, and the lid plate fixing piece 15 of the side plate 3 is inserted into the second insertion hole 17 of the insertion piece 9a for repacking. Is completed. In this state, since the tongue-like piece 23 is not inserted into the slit 25 and extends along the upper lid 9, the through-hole 27 is closed again by the tongue-like piece 23 as shown in FIG. The characters “opened” printed on the tongue-like piece 23 can be visually recognized from the outside.

  According to the above configuration, it can be confirmed at a glance whether or not the packaging box 100 has been opened, and it is easy to determine whether the internal replacement part is unused or used without opening the packaging box 100. Can be confirmed. Further, since no gluing is required at the time of packing using the packaging box 100, the number of members and the number of manufacturing steps can be reduced, and facilities such as a gluing device are not necessary, leading to cost reduction of the packaging box 100. Furthermore, since the packaging box 100 is not broken at the time of opening, dust such as the packaging box 100 or a piece of tape is not generated.

  FIG. 8 is a partially enlarged view of the packaging box 100 according to the second embodiment of the present invention, and is a partially enlarged view around the through hole 27 formed in the upper lid 9 in a state where the tongue-like piece 23 is bent and inserted into the slit 25. FIG. In FIG. 8, with the tongue-like piece 23 inserted into the slit 25, the insertion piece 9 a is inserted into the first insertion hole 13, and the lid plate fixing piece 15 is inserted into the second insertion hole 17, and the upper lid 9 and the inner lid 10. Is fixed in the closed state, the characters “unopened” are printed on the surface of the inner lid 10 exposed from the through hole 27 formed in the upper lid 9 by bending the tongue-like piece 23.

  According to the configuration of the present embodiment, when the replacement part used in the packaging box 100 is repacked, the tongue-like piece 23 is not inserted into the slit 25 but is extended along the upper lid 9. As shown, the through hole 27 is closed again by the tongue-like piece 23. Then, the tongue-shaped piece 23 overlaps with the characters “unopened” printed on the upper lid 10 and cannot be visually recognized from the outside. Therefore, similarly to the first embodiment in which the characters “opened” are printed on the tongue-like piece 23, it is easy to determine whether the internal replacement part is unused or used without opening the packaging box 100. Can be confirmed.

  In addition, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention. For example, the present invention is not limited to the B type type in which the bottom surface is formed by engaging the pair of bottom plates 5 and 6 and the pair of bottom flaps 7 and 8, but the side plates connected to the four sides of the rectangular bottom plate are arranged upward. It can be applied to packaging boxes of various assembling methods such as the A type type that is bent into two.

  Moreover, in each said embodiment, although the packaging box 100 of the structure which double-locks the upper cover 9 was demonstrated as an example using the insertion piece 9a and the cover plate fixing piece 15, the mechanism which locks the upper cover 9 is this. For example, the cover plate fixing piece 15 may not be used.

  Moreover, there is no restriction | limiting in particular also about the magnitude | size, shape, and arrangement | positioning of the tongue-shaped piece 23, According to the specification of the packaging box 100, it can design arbitrarily. For example, in the above embodiment, the tongue-like piece 23 is provided in the substantially central portion of the upper lid 9, and the slit 25 for inserting the tongue-like piece 23 is provided in the inner lid 10 that overlaps the inner side of the upper lid 9. It is also possible to provide the slits 25 in the lid flaps 11 and 12 with the slits 25 provided near the ends facing the lid flaps 11 and 12.

  In each of the above embodiments, the letter “opened” is printed on the surface of the tongue-like piece 23, or the surface of the inner lid 10 exposed from the through hole 27 formed in the upper lid 9 is “unopened”. The characters are printed to determine whether they are opened or unopened. However, if the characters are printed on both the surface of the tongue-like piece 23 and the surface of the inner lid 10, more reliable determination is possible. Is possible.

  Further, not only characters but also marks or symbols may be formed so as to be able to determine whether they have been opened or not. Further, if it is determined whether the tongue-like piece 23 is in a folded state (inserted into the slit 25) or in an extended state, it is not always necessary to have a mark. do not do.

  INDUSTRIAL APPLICABILITY The present invention can be used for a packaging box having an inner lid and an upper lid that are connected to the upper ends of opposing side plates. By using the present invention, it is possible to provide a packaging box having a simple configuration that is excellent in strength and airtightness, in which an open trace can be clearly recognized without the need for gluing at the time of packaging.
