  However, in the packaging box described in the above-mentioned Patent Document 1, there is a problem that the finger-hanging portion becomes waste and the disposal processing is necessary. On the other hand, in the packaging box described in Patent Document 2, a part of the cover plate tongue piece is left on the front plate. For example, when the opened packaging box is packed into a predetermined size storage box and managed in a predetermined unit (for example, a plurality of dozens) due to the structure of the packaging box in which the remaining part of the cover plate tongue is left on the front plate There is a problem that the arrangement form when stacked due to the presence of the remaining part of the cover plate tongue piece tends to be shifted and unstable.

  The present invention has been made to address the above-described problems, and its purpose is to provide a packaging box that does not generate waste when it is displayed as opened, and that can maintain a stable arrangement form even when stacked in a plurality. There is to do.

In order to achieve the above object, a packaging box of the present invention comprises a cylindrical or container-like box body and at least one lid body extending continuously from one end edge of the open end of the box body, At least one of the box body is an openable / closable lid that can be rotated with the edge of the box body as a fold line, and the box body can be opened and closed according to the rotation of the open / close lid,
The box body or the lid is formed with a predetermined shape of a pressing piece surrounded by a cut line and a bending line connecting both ends of the cut line, and the cover piece is arranged so as to overlap the back side of the push piece. ,
The base end of the cover piece is integrated with the box body or lid, and the free end of the cover piece is allowed to move inward of the box body with the base end as a fulcrum as the pushing operation proceeds. In a cantilever state,
When the pushing piece is pushed away from the box body or the cover body to a predetermined depth, the pushing piece gets over the free end of the cover piece and turns to the back side of the cover piece, and a part of the surface of the cover piece is It is exposed through an opening formed in the box body or the lid, and can be visually recognized as an opened display.

  In the packaging box of the present invention, the pushing piece is pushed toward the inside of the box main body, so that it passes over the free end of the cover piece and turns around to the back side of the cover piece. As a result, a part of the surface of the cover piece is exposed through the opening formed in the box body or the lid due to the separation of the pushing piece, and a part of the surface of the cover piece is visually recognized by the user as an unsealed display. It becomes like this. In this case, it is not necessary to use a specially shaped packaging box as described in Patent Document 2, and the pushing piece is prevented from moving outside the box body by the cover piece and protrudes outside the box body. Therefore, in the packaging box after resealing, the side surfaces can be stacked in a state of surface contact with each other, and a stable arrangement can be maintained. Furthermore, according to the present invention, a packaging box having an opened display function can be formed by simply providing a cover piece that is integral with or separate from the box body or lid, while providing a cut line in the existing box body. Therefore, since the existing box body can be used effectively, the manufacturing cost can be set at a low cost.

The first side plate 11, the front plate 12, the second side plate 13, the back plate 14 and the glue margin 15 are separated by fold lines (fold ruled lines, creases, edges) L1, L2, L3, L4 extending in parallel. It has been. The adhesive margin 15 is affixed to the back surface of the first side plate 11 in the assembled state of the box body 10 by the adhesive B1 (see FIG. 3B) applied to the surface. Thereby, the box main body 10 is integrated in the circumferential direction so as to form a rectangular tube shape.

  As shown in FIGS. 3A and 3B, the lid 20 includes an inner lid member 21, an outer lid piece 22, and flaps 23 and 24. The inner lid member 21 extends from one end edge of the front plate 12, and a first inner lid piece 21a, a second inner lid piece 21b, and a reseal piece 21c are connected in this order. The first inner lid piece 21a, the second inner lid piece 21b, and the reseal piece 21c are delimited by fold lines (folded crease lines, creases, and edges) L5 and L6 that extend in parallel.

  The first inner lid piece 21a shares an end edge with the front plate 12, and is formed in an isosceles trapezoidal shape having the end edge as a lower base. Specifically, the shared edge is composed of a fold line L7 located in the middle portion thereof, and cut lines C1 and C2 extending from both ends of the fold line L7 along the edge of the front plate 12, respectively. Is formed.

  The front plate 12 is surrounded by a fold line L7 and an isosceles trapezoidal shape having the fold line L7 as the bottom, or a substantially U-shaped cut line C3 having both ends of the fold line L7 as a start end and an end, respectively. Opened pieces 12a are formed. Thereby, the inner lid member 21 can be separated from the front plate 12 together with the opening piece 12a by breaking at the cut lines C1, C2, and C3.

  The first inner lid piece 21a and the second inner lid piece 21b are formed in an isosceles trapezoidal shape with the fold line L5 as a common upper base, the lower bases and the heights having substantially the same length. The resealable piece 21c is formed in an arc shape at both corners at the tip. The second inner lid piece 21b is folded at a fold line L5 (see FIG. 4), and is adhered to the back surface of the first inner lid piece 21a by the adhesive B2 (see FIG. 3A) applied to the back surface thereof. The inner lid pieces 21a and 21b are accommodated in the box body 10 in an integrated state (see FIG. 2). The inner lid member 21 having the first inner lid piece 21a and the second inner lid piece 21b corresponds to the cover piece of the present invention that functions as an unsealed display.

  As shown in FIGS. 3A and 3B, the outer lid piece 22 has a rectangular shape large enough to include the folded first inner lid piece 21a and second inner lid piece 21b (see FIG. 3). 5), extending from one end edge of the back plate 14 and separated from the back plate 14 by a folding line L8. The outer cover piece 22 includes a fold line L8 and a cut line C4 having a substantially U shape (other arc shape or square shape may be used) having two points of the middle part of the fold line L8. An enclosed push-in piece 22a is formed. The pushing piece 22a is separated from the outer lid piece 22 by breaking at the cut line C4, and the pushing piece 22a after being separated can be rotated about the bending line L8 as a rotation axis.

  The flaps 23 and 24 close a part of the opening of the box body 10, and are separate from the edges of the opening ends of the box body 10 to which the first inner lid piece 21 a and the outer lid piece 22 are respectively connected. It extends from the edge. Specifically, the flap 23 extends from one end edge of the first side plate 11 and is separated from the first side plate 11 by a folding line L9. The flap 24 extends from one end edge of the second side plate 13 and is separated from the second side plate 13 by a folding line L10.

  The outer lid piece 22 is folded along a folding line L8, so that the first inner lid piece 21a is superimposed on the surface of the first inner lid piece 21a and is applied to the back surface by the adhesive B3 (see FIG. 3A). (See FIGS. 2 and 4). In this case, both the inner lid pieces 21a and 21b are accommodated between the outer lid piece 22 and the flaps 23 and 24, while the resealable piece 21c is substantially perpendicular to the second inner lid piece 21b by the fold line L6. It is bent and inserted into the inside of the box body 10 through a gap S1 formed between the edge of the flaps 23, 24 and the front plate 12. The inner lid member 21 and the outer lid piece 22 correspond to the opening / closing lid of the present invention.

  As shown in FIGS. 3A and 3B, the lid 30 includes an inner lid piece 31, an outer lid piece 32, and flaps 33 and 34. The inner lid piece 31 extends from the other end edge of the front plate 12 and is separated from the front plate 12 by a folding line L11. The outer lid piece 32 extends from the other end edge of the back plate 14 and is separated from the back plate 14 by a folding line L12.

  The flap 33 extends from the other end edge of the first side plate 11 and is separated from the first side plate 11 by a folding line L13. The flap 34 extends from the other end edge of the second side plate 13 and is separated from the second side plate 13 by a folding line L14.

  The outer lid piece 32 is folded on the folding line L12 so as to be superimposed on the surface of the inner lid piece 31 and adhered to the surface of the inner lid piece 31 with the adhesive B4 (see FIG. 3A) applied to the back surface. (See FIG. 4). In this case, the inner lid piece 31 is accommodated between the outer lid piece 32 and the flaps 33 and 34. As described above, in the first embodiment, the lid 20 is openable and closable, and the lid 30 is normally closed.

  In the packaging box 1A configured as described above, the inner lid member 21 and the outer lid are separated by cutting the opening pieces 12a of the front plate 12 along the cut lines C1, C2, C3 as shown in FIG. The piece 22 functions as an integral opening lid, and the re-sealing piece 21c is inserted into the inside of the box body 10 so that the opened packaging box 1A is closed again, and the opening and closing is repeated. You can also.

  By the way, in the present Example 1, the outer cover piece 22 is affixed on the 1st inner cover piece 21a, and the inner cover member 21 is arrange | positioned so that it may overlap with the pushing piece 22a partially. In this case, assuming that the vertical dimension of the outer lid piece 22 is D3 and the height dimension of the first inner lid piece 21a is D4, D3> D4 is set, and the pushing piece 22a is set along the cut line C4. When pushed into the inside of the box body 10 while being cut off, the pushing piece 22a is configured to easily go over the free end portion on the distal end side of the inner lid member 21 and turn around to the back side of the inner lid member 21.

  Specifically, as shown in FIGS. 6 and 7A, the pushing piece 22a is moved in the direction of the arrow in the state in which the inner lid member 21 is opened from the box body 10 by a predetermined angle or more (for example, 45 ° or more). When pushed in, the pushing piece 22a is separated from the outer lid piece 22, and turns inside the box body 10 with the bending line L8 as the turning axis (FIG. 7B).

  The inner lid member 21 is affixed to the outer lid piece 22 in the vicinity of the lower bottom of the first inner lid piece 21a, and this affixed part is used as a base end E1 and the first inner lid piece 21a and the second inner lid. The part near the upper base of the piece 21b is a free end E2, and the base end E1 is a fulcrum part so as to be allowed to be displaced inward of the box body 10. Thereby, the inner lid member 21 is displaced inward of the box body 10 following the displacement of the pushing piece 22a accompanying the pushing operation (FIG. 7B).

  When the pushing piece 22a is separated from the outer lid piece 22 and pushed to the inside of the box body 10 to a predetermined depth, the pushing piece 22a is free ends E2 of the first inner lid piece 21a and the second inner lid piece 21b. Go over to the back side (Fig. 7 (c)). In this state, when the resealable piece 21c is inserted into the inside of the box body 10 and the box body 10 is closed, the pushing piece 22a receives a slight reaction force based on the elastic return of the flaps 23 and 24 and the like, and the inner lid member 21 And the flaps 23 and 24 (FIG. 7D).

  At this time, when the outer lid piece 22 is viewed from the front, the first through the opening 22b formed in the outer lid piece 22 by the separation of the pushing piece 22a (that is, the hole surrounded by the cut line C4 and the folding line L8). The surface of the upper bottom side intermediate portion 21a1 of the inner lid piece 21a is exposed (FIG. 7E).

  As is clear from the above description, in the first embodiment, the pushing piece 22a is pushed toward the inside of the box body 10 so that the pushing piece 22a forms the free end E2 of the inner lid member 21 (cover piece). Get over and go around to the back side of the inner lid member 21. Thereby, the surface of the inner lid member 21 is exposed through the opening 22b formed in the outer lid piece 22 due to the separation of the pushing piece 22a, and a part of the surface of the first inner lid piece 21a in the inner lid member 21 is obtained. The (upper bottom side intermediate portion 21a1) is visually recognized by the user as an unsealed display.

  In this case, the pushing piece 22a is prevented from moving outside the box body 10 by the inner lid member 21, and there is no possibility of projecting outside the box body 10. Can be stacked while being in surface contact with each other, and a stable arrangement can be maintained.

  In the first embodiment, when the inner lid member 21 and the outer lid piece 22 as the opening / closing lid are in a closed state with respect to the box body 10, the inner lid member follows the displacement of the pushing piece 22a accompanying the pushing operation. 21 and the flaps 23 and 24 come into contact with the contents 3 in the box body 10, so that the inner lid member 21 and the flaps 23 and 24 are prevented from being displaced to the inside of the box body 10, and the pushing piece 22 a is It was comprised so that climbing over the free end E2 of the member 21 might be prevented.

  That is, in the first embodiment, as shown in FIGS. 7A to 7C, the inner lid member 21 and the outer lid piece 22 are not restrained from being displaced toward the inside of the box body 10. On the condition that the lid member 21 and the outer lid piece 22 are open with respect to the box body 10, the pushing piece 22 a is moved in accordance with the displacement of the inner lid member 21 and the outer lid piece 22 toward the inside of the box body 10. It was set as the structure accept | permitted over the free end part E2 of the cover member 21 and the outer cover piece 22. As shown in FIG.

  Thereby, in the said Example 1, since the surface of the 1st inner cover piece 21a cannot be made to be visually recognized as an unsealed display unless the packaging box 1A is opened by the cover body 20 side, the packaging box 1A is not opened. In spite of this, it is possible to satisfactorily prevent forgery and tampering that pretend to be opened.

  In the first embodiment, the inner lid member 21 as a cover piece is formed integrally with the box body 10. Thereby, the packaging box 1A can be assembled simply and efficiently using only one sheet for forming a box body 2A. Furthermore, in the said Example 1, the packaging box 1A can be comprised only by providing the cut line C4 in the existing box main body as shown, for example in FIG. 3 (a), 3 (b). Therefore, since the existing box body can be used effectively, the manufacturing cost can be set at a low cost.

  In the packaging box 1A of the first embodiment, the lid body 20 has two inner lid pieces 21a and 21b as the inner lid member 21, and the inside of the packaging box 1A on the condition that the lid 20 is opened with the opening piece 12a formed on the front plate 12. The lid member 21 and the outer lid piece 22 are integrated to function as an opening lid. However, the configuration is not limited to the first embodiment, and for example, a configuration as shown in FIGS. 8 to 10, the same reference numerals are given to the portions that perform the same functions as those in the first embodiment, and the description thereof is omitted.

  The packaging box 1B of Example 2 is a tack-end type carton, and is assembled into a rectangular parallelepiped shape as shown in FIG. 9 by using the box forming sheet 2B shown in FIG. The box forming sheet 2 </ b> B is formed of a single blank sheet such as cardboard, and includes a box body 10 and lid bodies 20 and 30 at each opening end of the box body 10. The box body 10 and the lid body 30 are configured in the same manner as in the first embodiment.

  The lid 20 includes an outer lid piece 22 and flaps 23 and 24, and the inner lid piece is omitted. The outer cover piece 22 is formed with a push-in piece 22a, and a re-sealing piece 22c is extended from a tip edge of the outer cover piece 22 via a fold line L6.

  A cover sheet 25, which is a separate member from the box forming sheet 2 </ b> B, is attached to the back surface of the outer lid piece 22. The cover sheet 25 is formed of, for example, a convex cardboard as shown in FIG. 8B, and as shown in FIG. 9, the sheet body 25a is arranged so as to partially overlap the pushing piece 22a, It sticks to the back surface of the outer lid piece 22 with an adhesive B5 at the protruding portion 25b. That is, the cover sheet 25 is a cantilever that is allowed to displace inside the box body 10 with the intermediate protrusion 25b as a base end E1, the sheet body 25a as a free end E2, and the base end E1 as a fulcrum part. It is in a state. The cover sheet 25 corresponds to the cover piece of the present invention that functions as an unsealed display.

  And as an example, as shown in FIG. 10 (a), when the outer cover piece 22 is opened from the box body 10 by a predetermined angle or more (for example, 45 ° or more), the pushing piece 22a is pushed in the direction indicated by the arrow, The pushing piece 22a is separated from the outer lid piece 22, and turns to the inside of the box body 10 with the bending line L8 as a turning axis (FIG. 10B). When the pushing piece 22a is separated from the outer lid piece 22 and pushed toward the inside of the box body 10 to a predetermined depth, the pushing piece 22a gets over the free end E2 of the cover sheet 25 and turns to the back side (FIG. 10). (C)).

  In this state, when the resealable piece 22c is inserted into the box body 10 and the box body 10 is closed, the pushing piece 22a receives the slight reaction force based on the elastic recovery of the flaps 23 and 24, and the like. It will be clamped by the cover piece 22 and the flaps 23 and 24 (FIG. 10 (d)). At this time, when the outer lid piece 22 is viewed from the front, the cover sheet passes through the opening 22b (that is, the hole surrounded by the cut line C4 and the folding line L8) formed in the outer lid piece 22 by the separation of the pushing piece 22a. 25, the surface of the intermediate portion 25a1 of the sheet main body 25a is exposed (FIG. 10E).

  In Example 2, a part of the surface of the cover sheet 25 (intermediate portion 25a1) is visually recognized by the user as an unsealed display. And also in the packaging box 1B after the reseal in this Example 2, it can pile up in the state which mutually contacted each other, and can maintain the stable arrangement | positioning form.

  Moreover, in the said Example 2, since the cover sheet 25 is comprised by the member different from the sheet | seat 2B for box bodies formation, the visual recognition effect with respect to a user is improved favorably by changing the raw material of the cover sheet 25 suitably. Is possible. Further, in the second embodiment, for example, a cut line C4 is simply provided in the existing box body as shown in FIG. 8A, for example, and a cover sheet as a separate member as shown in FIG. 8B, for example. The packaging box 1B can be configured simply by adding 25. Therefore, also in the second embodiment, since the existing box body can be used effectively, the manufacturing cost can be set at a low cost.

  In the second embodiment, the cover sheet 25 is configured to function as a cover piece. However, as shown in FIGS. 11 and 12, for example, the cover sheet 25 is omitted and the flaps 23 and 24 are covered. You may comprise so that the function as a piece may be fulfill | performed. In FIGS. 11 and 12, the same reference numerals are given to portions that perform the same functions as those in the second embodiment, and the description thereof is omitted.

  The packaging box 1C of the third embodiment is assembled using a box forming sheet based on the box forming sheet 2B of the second embodiment. However, unlike the second embodiment, even when the outer lid piece 22 is closed with respect to the box body 10, the flaps 23 and 24 that follow the displacement of the pushing piece 22 a accompanying the pushing operation are provided on the box body 10. With the displacement inward, the shapes of the flaps 23 and 24 are changed so that the pushing pieces 22a can easily get over the end edges 23a and 24a of the flaps 23 and 24 near the back plate 14. However, the size of the flaps 23 and 24 themselves can be effectively used from the existing box body and is not particularly restricted.

  That is, the gap S2 between the edge 23a of the flap 23 and the back plate 14 gradually increases from the side of the folding line L9 that is the base end of the flap 23 toward the front end that is the free end of the flap 23. The edge 23a of the flap 23 is formed in an inclined shape. Similarly, the gap S <b> 2 between the edge 24 a of the flap 24 and the back plate 14 gradually increases from the side of the folding line L <b> 10 that is the base end portion of the flap 24 toward the front end side that is the free end portion of the flap 24. The edge 24a of the flap 24 is formed in an inclined shape.

  In the third embodiment, the flaps 23 and 24 follow the displacement of the push-in piece 22a accompanying the push-in operation, and are displaced inward of the box body 10 with the bending lines L9 and L10 as the rotation axes, respectively (FIG. 12A). ). In addition to the formation of the gap S2 between the end edge 23a of the flap 23 and the back plate 14 and the gap S2 between the end edge 24a of the flap 24 and the back plate 14, the outer shape of the pushing piece 22a is formed in an arc shape. The pushing piece 22a goes around to the back side of the flaps 23 and 24 through the gap S2 without the flaps 23 and 24 coming into contact with the contents 3 in the box body 10 (FIG. 12B).

  The pushing piece 22a presses the flaps 23 and 24 to the outside of the box body 10 with a slight elastic force by its own elastic recovery or the like (FIG. 12C). At this time, when the outer lid piece 22 is viewed from the front, the flap 23 passes through the opening 22b formed in the outer lid piece 22 by separation of the pushing piece 22a (that is, a hole surrounded by the cut line C4 and the folding line L8). 24, the surfaces of the corners 23b and 24b including a part of each edge 23a and 24a are exposed (FIG. 12D).

  In Example 3, a part of the surface of the flaps 23 and 24 (corner portions 23b and 24b) is visually recognized by the user as an unsealed display. And also in packaging box 1C after this reseal in Example 3, it can be piled up in the state which mutually contacted each other, and the stable arrangement form can be maintained.

  Moreover, in the said Example 3, the flaps 23 and 24 are comprised so that the function as a cover piece may be fulfill | performed. Thereby, the opened display function can be realized with a simple configuration. Further, in the third embodiment, the packaging box 1C can be configured simply by providing the cut line C4 (see FIG. 8) in the existing box body as shown in FIG. Therefore, also in the third embodiment, since the existing box body can be effectively used, the manufacturing cost can be set at a low cost.

  In the said Example 3, it was comprised so that the flaps 23 and 24 might fulfill | perform the function as a cover piece, For example, as FIG.13 and FIG.14 shows, a part of the glue margin 15 of Examples 1-3 is used. You may comprise so that the used inner piece 16 may function as a cover piece. In FIGS. 13 and 14, parts having the same functions as those in the first to third embodiments are denoted by the same reference numerals and description thereof is omitted.

  The packaging box 1D of Example 4 is assembled using a box forming sheet 2D based on the box forming sheet 2B of Example 2 described above. However, unlike the second embodiment, the pushing piece 11 a is formed on the first side plate 11. Further, the adhesive margin 15 of the second embodiment is reduced to about half the length, and the remaining inner piece 16 to which no adhesive is applied functions as a cover piece.

  In the fourth embodiment, following the displacement of the pushing piece 11a accompanying the pushing operation, the inner piece 16 is displaced to the inside of the box body 10 with the bending line L4 as the rotation axis. Then, the pushing piece 11a goes around to the back side of the inner piece 16 through the gap S3 between the end edge 16a of the inner piece 16 and the outer lid piece 22. In this case, the pushing piece 11 a and the inner piece 16 are set so as not to contact the contents 3 in the box body 10.

  The pushing piece 11a presses the inner piece 16 toward the back surface of the first side plate 11 with a slight elastic force by its own elastic recovery or the like. At this time, when the first side plate 11 is viewed from the front, the opening 11b (that is, a hole surrounded by the cut line C4 and the folding line L9) formed in the first side plate 11 due to the separation of the pushing piece 11a. The surface of the corner 16b including a part of the edge 16a of the inner piece 16 is exposed.

  In Example 4 described above, a part of the surface of the inner piece 16 (corner portion 16b) is visually recognized by the user as an unsealed display. And also in packaging box 1D after the reseal in this Example 4, it can pile up in the state which mutually contacted each other, and can maintain the stable arrangement | positioning form.

  Moreover, in the said Example 4, the inner piece 16 using a part of glue margin 15 is comprised so that the function as a cover piece may be fulfill | performed. As a result, as in the third embodiment, the opened display function can be realized with a simple configuration. Further, in the fourth embodiment, for example, the existing box body as shown in FIG. 13 is simply provided with the cut line C4, and the inner piece 16 is formed by effectively using the existing glue margin. 1D can be configured. Therefore, also in the fourth embodiment, since the existing box body can be effectively used, the manufacturing cost can be set at a low cost.

  In the first to fourth embodiments, the lid 30 is normally closed. However, an opening / closing type having a pushing structure similar to that of the lid 20 may be employed, or a normal opening / closing type that is not a pushing structure may be employed. It is good also as a structure of a formula.

  Further, for example, in the first to third embodiments, the formation position of the pushing piece 22a can be appropriately changed along the folding line L8, or alternatively, any position in the outer lid piece 22 away from the folding line L8. It can also be a position. The same applies to the pushing piece 11a of the fourth embodiment.

  In addition, the packaging boxes 1A, 1B, 1C, and 1D of the above-described Examples 1 to 4 are only one application example of the present invention. Can be implemented in a manner in which various changes are made to the packaging boxes 1A, 1B, 1C, and 1D without departing from the spirit of the invention.

  The present invention is not limited to the packaging boxes 1A, 1B, 1C, and 1D of the first to fourth embodiments. For example, a lock bottom carton (a box that can be assembled with a single touch) or a collapsible carton with a lid (container shape) The present invention can be applied to various packaging boxes such as a box in which a lid is connected to the box body. Furthermore, the present invention is not limited to a rectangular parallelepiped shape in the assembled state such as the packaging boxes 1A, 1B, 1C, and 1D of the first to fourth embodiments. For example, a solid body other than the rectangular parallelepiped shape such as a cylindrical shape or a triangular prism shape is used. It is possible to apply to various packaging boxes having a shape.
