  There is a type of packaging container in which the opening of the main body is closed with a single cover plate. Some containers of this type close the lid plate by inserting an insertion piece connected to the lid plate into the main body.

  In this type of packaging container, there is a case where the lid plate and the main body are bonded with an adhesive member such as a seal, or an insertion piece is engaged with the main body so that the lid plate does not open unintentionally. In this case, it is difficult to open the packaging container.

  In this specification, the technique which can open a packaging container smoothly is disclosed.

  The technology disclosed in this specification relates to a packaging container. The packaging container includes a main body having an opening, a cover plate that is connected to the main body, opens and closes the opening, and an insertion piece that is connected to an end side of the cover plate. The insertion piece is inserted into the main body from the edge of the lid plate beyond the edge of the first wall plate constituting the main body in a state where the opening of the lid plate is closed, and along the inner surface of the first wall plate. Be placed. The first wall plate is separated by a slit portion in which slits are intermittently arranged with other portions of the first wall plate in at least a part of a portion overlapping with the insertion piece of the first wall plate. And a deformable portion that is disposed adjacent to the separation portion via the slit portion and can be deformed to the inside of the main body with respect to the separation portion when pressed from the outside of the wall plate.

  In said structure, an insertion piece is inserted in a main body and a cover plate is closed. At this time, in many cases, measures are taken to prevent the lid plate from being unintentionally opened, such as bonding the lid plate and the first wall plate or engaging the insertion piece and the main body. In the above configuration, at the time of opening, the deformed portion is deformed inside the packaging container with a user's finger or the like, and the finger or the like is hooked on the edge of the separating portion on the deformed portion side and pulled outside the packaging container. Thus, the separation part can be separated from the other part of the first wall plate. The separation part is separated from the other part of the first wall plate by the slit part, and can be easily separated. As a result, since the separation part and the other part of the first wall plate are separated from each other, the packaging container can be easily opened. According to this configuration, the packaging container can be opened smoothly.

  The main features of the embodiments described below are listed. The technical elements described below are independent technical elements and exhibit technical usefulness alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. Absent.

(Feature 1) In the packaging container disclosed in the present specification, the edge of the insertion piece opposite to the cover plate overlaps with the position of the edge opposite to the edge of the first wall plate of the separation portion. It may be. The deformation part may be adjacent to the edge of the separation part via the slit part. According to this configuration, the separation portion and the insertion piece can be pulled simultaneously with the user's finger or the like inserted from the deformation portion. Thereby, when separating the separation part from the other part of the first wall plate, the cover plate can be moved by pulling the insertion piece to open the storage container.

(Feature 2) In the packaging container disclosed in this specification, the lid plate is bent with respect to the first lid plate covering the opening and the first lid plate, and overlaps with the second wall plate constituting the opening. And a second lid plate to be provided. The second wall plate may be bent and connected to the first wall plate at the end of the first wall plate. An insertion hole may be provided on the end side of the first wall plate between the first wall plate and the second wall plate. The separating portion extends from the first wall plate to the second wall plate, and may include an insertion hole. The insertion piece may be inserted into the insertion hole. According to this structure, a 2nd wall board and a 2nd cover board can be arrange | positioned doubly. Thereby, the intensity | strength of a storage container can be improved.

(Feature 3) In the packaging container disclosed in the present specification, the first wall plate has a flap that extends in parallel to the cover plate from the end side of the first wall plate in a state where the cover plate closes the opening. It may be. You may have the opening in which an insertion piece is inserted in the edge part of the edge of the 1st wall board of a flap. The separation part may surround the opening. According to this configuration, the cross section of the first wall plate can be made invisible at the end side of the first wall plate in a state where the opening of the lid plate is closed. Thereby, it can prevent that the cross section of a 1st wall board is visible to the external appearance of a packaging container in the state which has closed the cover plate. In the packaging container disclosed in the present specification, in addition to the first wall plate, a flap extending in parallel with the lid plate is disposed on the side edge of the wall plate that defines the main body of the packaging container. Also good.

According to this configuration, the packaging container can be opened without the insertion piece coming into contact with the first wall plate.

(First embodiment)
FIG. 1 shows a perspective view of the packaging container 10. The packaging container 10 is used, for example, for packaging a delivery item in a delivery service. FIG. 2 shows a blank BL in which the packaging container 10 is developed. The packaging container 10 is produced by assembling one blank BL. The packaging container 10 is made of strong paper such as cardboard. The material of the packaging container 10 is not limited to paper, and may be a material other than paper such as resin. In this specification, for the sake of convenience, the front, rear, left, right, up and down directions are defined in the direction shown in FIG. The height direction is parallel to the vertical direction.

  As shown in FIGS. 1 and 2, the packaging container 10 includes a main body 40, a lid plate 12, and an insertion piece 50. The main body 40 has an opening 42 (see FIG. 4) at the upper end. The main body 40 includes a bottom plate 20 and four side plates 18, 26, 28, 36. The bottom plate 20 and the four side plates 18, 26, 28, 36 can be called “wall plates” of the main body 40.

  The bottom plate 20 has a rectangular flat plate shape. Side plates 18, 26, 28, and 36 are connected to the four end sides of the bottom plate 20, respectively. FIG. 2 shows the four edges of the bottom plate 20, that is, the boundaries between the bottom plate 20 and the side plates 18, 26, 28, and 36 by a one-dot chain line. A concave groove is provided at a position indicated by a one-dot chain line in FIG. 2 including the boundary between the bottom plate 20 and the side plates 18, 26, 28, and 36 so as to be easily bent. Each of the side plates 18, 26, 28, and 36 has a trapezoidal flat plate shape in which the lower end side, that is, the side overlapping the end side of the bottom plate 20 is shorter than the upper end side. The side plates 18, 26, 28, 36 are each bent upward from the blank BL shown in FIG. 2 at the boundary with the bottom plate 20, thereby producing the main body 40. In the main body 40, the side plate 28 is bonded to the bonding portion 22 extending from the right end of the side plate 18 and the bonding portion 23 extending from the right end of the side plate 36. Further, the side plate 26 is bonded to the bonding portion 24 extending from the left end of the side plate 18 and the bonding portion 25 extending from the left end of the side plate 36. Thereby, in the main body 40, the side plates 18, 26, 28, and 36 are maintained in a rectangular cylindrical shape. Since the side plates 18, 26, 28, 36 are trapezoidal, the cross section perpendicular to the vertical direction of the main body 40 gradually widens from the lower end toward the upper end. The opening 42 (see FIG. 4) of the main body 40 is defined by the upper end sides of the side plates 18, 26, 28, 36.

  A flap 32 is connected to the upper end of the left side plate 26. As shown in FIG. 4, the flap 32 is bent inside the main body 40. At the boundary between the side plate 26 and the flap 32 (that is, the upper end side of the side plate 26), so-called perforations in which relatively short slits are intermittently arranged so as to be easily bent are arranged. Thereby, the user can bend the flap 32 easily. Further, an insertion slit 30 into which an insertion piece 16 to be described later is inserted is disposed at the center of the boundary between the side plate 26 and the flap 32. The insertion slit 30 passes through the boundary between the side plate 26 and the flap 32. A flap 34 is connected to the upper end of the right side plate 28. Since the relationship between the side plate 28 and the flap 34 is the same as the relationship between the side plate 26 and the flap 32, detailed description thereof is omitted.

  An insertion hole 52 is disposed at the boundary between the front side plate 36 and the bottom plate 20. The insertion hole 52 has a slit shape extending in the left-right direction, and penetrates the boundary between the side plate 36 and the bottom plate 20. Specifically, both ends of the insertion hole 52 are located on the boundary line between the side plate 36 and the bottom plate 20, and an intermediate portion of the insertion hole 52 is shifted to the side plate 36 side in a blank BL state. According to this configuration, when the side plate 36 is bent from the state of the blank BL and deformed into the main body 40, the insertion hole 52 is opened by the amount shifted to the side plate 36 side.

  In the region surrounding the insertion hole 52, a separation portion 60 is disposed. The separation part 60 extends from the vicinity of the front end of the bottom plate 20 to the upper end side of the side plate 36 beyond the front end side 20a. The separation portion 60 is separated from the other portions of the bottom plate 20 and the side plate 36 by the slit portion 54. In the slit portion 54, a short straight slit penetrating the bottom plate 20 or the side plate 36 is intermittently arranged. The shape of the slit is not limited to a linear shape, and may be bent or curved at one or more places. In other words, the slit part 54 should just be an aspect in which the other part of the bottom plate 20 and the side plate 36 and the separation part 60 can be easily separated.

  A deforming portion 58 is disposed on the rear end side of the separation portion 60 of the bottom plate 20. The deformation part 58 is adjacent to the separation part 60 via the slit part 54. The deformation portion 58 has a rectangular shape, the front end side is in contact with the separation portion 60 via the slit portion 54, and the left and right end sides are respectively connected to other portions of the bottom plate 20 via the slit 56. It is delimited. The slit 56 passes through the bottom plate 20.

  The lid plate 12 is connected to the upper end of the rear side plate 18. A so-called perforation in which relatively short slits are intermittently arranged is arranged between the side plate 18 and the lid plate 12 so as to be easily bent. The lid plate 12 has two lid plates 13 and 14. The lid plate 13 has a rectangular flat plate shape. The lid plate 13 has the same shape as the opening 42 of the main body 40. The opening 42 can be opened and closed by rotating the lid plate 13 with respect to the side plate 18 at the upper end of the side plate 18. Insert pieces 16 are connected to the left and right ends of the cover plate 13 in the center in the front-rear direction. The insertion piece 16 is bent downward with respect to the cover plate 13 and inserted into the insertion slit 30. Thereby, it can suppress that the cover plate 13 bends and the clearance gap is formed between the cover plate 13 and the main body 40 in the state in which the cover plate 13 is closed.

  A lid plate 14 is connected to the front end of the lid plate 13 (the rear end of the lid plate 13 in FIG. 2). The lid plate 14 is bent downward with respect to the lid plate 13. The cover plate 14 has the same shape as the side plate 36 except for a configuration in which the lower end corner is rounded. The lid plate 14 is provided over the entire length of the lid plate 13 in the left-right direction.

  An insertion piece 50 is connected to the center of the lower end side 14a of the cover plate 14 (the rear end of the cover plate 14 in FIG. 2). As the insertion piece 50 is separated from the cover plate 14, the width in the left-right direction is narrowed. The maximum width in the left-right direction of the insertion piece 50 (that is, the end of the insertion piece 50 on the cover plate 14 side) is substantially the same as the length of the insertion hole 52 in the left-right direction. The length of the insertion piece 50 in the front-rear direction is the same as the length in the front-rear direction of the portion of the separating portion 60 disposed on the bottom plate 20.

  When the packaging container 10 is closed, the cover plate 12 is arranged such that the insertion piece 16 is inserted into the insertion slit 30, the cover plate 13 closes the opening 42, and the cover plate 14 overlaps the outside of the side plate 36. The insertion piece 50 is inserted into the main body 40 from the insertion hole 52 (in the direction of the arrow in FIG. 5), and is disposed along the inner surface of the bottom plate 20 beyond the front end side 20 a of the bottom plate 20. In this state, as shown in FIG. 5, the rear end side 50 a of the insertion piece 50 overlaps the slit portion 54 at the rear end of the separation portion 60.

  In the packaging container 10, in order to prevent a situation in which the insertion piece 50 is detached from the insertion hole 52 and the lid plate 12 is opened during transportation, the lid plate 14 and the separation portion 60 of the bottom plate 20 are separated at the center in the left-right direction. There may be a case where a sticker SL is applied. At the time of opening, the user pushes the deformable portion 58 into the main body 40 with a finger. The deformed portion 58 is easily separated from other portions of the bottom plate 20 by the slit 56 and the slit portion 54 except for the rear end side. For this reason, the deformation | transformation part 58 rotates centering on a rear-end side with a pressing force. The user can deform the deformable portion 58 with a relatively weak force.

  When the deforming portion 58 is deformed, the finger F is inserted into the packaging container 10. Thereby, the user can hook the finger F on the part where the insertion piece 50 and the separation part 60 overlap. The user hooks the finger F on the insertion piece 50 and the separation portion 60 and pulls it to the outside of the main body 40, thereby moving the separation portion 60 from the bottom plate 20 and other portions of the side plate 36 along the slit portion 54. Can be separated. Thereby, the user can open the packaging container 10 without peeling or breaking the seal SL.

  As shown in FIG. 4, even if the separation portion 60 is separated from the bottom plate 20 and the side plate 36, the separation portion 60 is engaged with the insertion piece 50, thereby preventing the separation portion 60 from being separated from the lid plate 12. can do.

  Further, the deformable portion 58 has a size enough to insert one finger F of the user. By making the deformation part 58 as small as possible, it is possible to prevent the deformation part 58 from being unintentionally deformed.

(Second embodiment)
With reference to FIGS. 5-8, a different point from the packaging container 10 of 1st Example is mainly demonstrated. FIG. 5 shows a state where the packaging container 100 is closed, and FIG. 6 shows a state where the packaging container 100 is opened. 5 and FIG. 6 have different viewpoints. FIG. 7 shows a development view of the packaging container 100, and FIG. 8 shows a perspective view of the packaging container 100 after opening as seen from a viewpoint similar to FIG. The packaging container 100 includes a main body 140 and a lid plate 102. The main body 140 has a rectangular parallelepiped shape having four side plates 118, 126, 128, 136 and a bottom plate 120. The bottom plate 120 is divided into four parts, each of which is rotatably connected to the lower end side of each of the four side plates 118, 126, 128, 136. The opening 142 at the upper end of the main body 140 is closed by the lid plate 102. The cover plate 102 is rotatably connected to the upper end of the side plate 118.

  The cover plate 102 has an insertion piece 104 that is bent downward and inserted into the main body 140 in a state where the cover plate 102 closes the opening 142. The insertion piece 104 is located at the center in the left-right direction of the lid plate 102. The lateral width of the insertion piece 104 is smaller than the lateral width of the cover plate 102. The insertion piece 104 is connected to the front end side 102 a (the upper end side in FIG. 6) of the lid plate 102. The insertion piece 104 is disposed so as to overlap the inner surface of the side plate 136 beyond the upper end side 136 a of the front side plate 136.

  The side plate 136 has a flap 136b disposed on the upper end side 136a. The flap 136b has a trapezoidal flat plate shape. One bottom side of the flap 136b overlaps the upper end side 136a over the entire length in the left-right direction, and the other bottom side of the flap 136b is separated from the upper end 136a and is shorter than the one bottom side. The flap 136b is rotatably connected to the front end portion of the side plate 136. The flap 136b overlaps the lid plate 102 in parallel with the lid plate 102 closing the opening 142. An opening 136c into which the insertion piece 104 is inserted is disposed at the center in the left-right direction on the upper end side 136a side of the flap 136b. The opening 136c penetrates the side plate 136.

  The length of the opening 136c in the front-rear direction is substantially the same as the plate thickness of the insertion piece 104, and the length in the left-right direction is substantially the same as the left-right direction of the insertion piece 104. In the flap 136b, a separating portion 108 is disposed by a slit portion 106 surrounding the opening 136c. The separating portion 108 extends from the end of the flap 136b on the side plate 118 side to the upper end side 136a and extends downward from the upper end side 136a. The separation part 108 is distinguished from other parts of the side plate 136 by a slit part 106 similar to the slit part 54. The left and right widths of the separating portion 108 are widened upward. The slit portion 106 at the lower end of the separation portion 108 is disposed at a position overlapping the lower end side of the insertion piece 104. The width in the left-right direction of the separating portion 108 is smaller than the width in the left-right direction of the insertion piece 104. Further, the width of the separation portion 108 of the flap 136b is narrowed toward the rear from the upper end side 136a.

  A deforming portion 112 similar to the deforming portion 58 is disposed at the lower end of the separating portion 108 via the slit portion 106. The deformable portion 112 is separated from other portions of the side plate 136 by a pair of slits 110.

  The flaps 126b and 128b are also arranged on the upper end sides 126a and 128a of the side plates 126 and 128, respectively. The flaps 126b and 128b are rotatably arranged, respectively. The flaps 126b and 128b overlap the cover plate 102 in parallel with the cover plate 102 closing the opening 142. Since the flaps 126b, 128b, and 136b are disposed, the cross section of the end portion of the side plates 126, 128, and 136 can be hidden while the cover plate 102 closes the opening 142. Moreover, it can suppress that the contents of the packaging container 100 fall from between the cover plate 102 and the main body 140.

  Similarly to the packaging container 10 of the first embodiment, the user presses the deformed portion 112 of the packaging container 100 with a finger, inserts the finger into the main body 140, and places the finger on the insertion piece 104 and the separating portion 108. By pulling and pulling, the packaging container 100 can be opened without peeling off the seal SL. As a result, as shown in FIG. 8, even if the separation portion 108 is separated from the side plate 136, the separation portion 108 is engaged with the insertion piece 104, so that the separation portion 108 is separated from the lid plate 102. Can be prevented.
