  In the case of the storage box described in the above-mentioned Patent Document 1, the applicant can open the opening / closing lid by slightly overdoing the switching to a substantially flat folding position while folding the bottom plate to the inside of the storage box. The bottom plate is folded inward, and the contents stored in the storage box can be removed or replaced with another one. Even when the lid is closed with a tamper-proof seal, the bottom plate is moved inward. It was found that there was a problem that it was possible to push in and remove or replace the contents. Moreover, if the contents are removed or replaced in this way, the tamper-proof seal is not removed, so the discovery of the removal or replacement is delayed, making it difficult to identify the criminal, It is also possible to sell the product without knowing the replacement.

  An object of the present invention is to provide a storage box that can effectively prevent the removal and replacement of the contents by pushing the bottom plate inward.

  The first storage box according to the present invention includes four side plates and four bottom plates connected to the lower ends of the four side plates, and in the assembly posture in which the two bottom plates are assembled in a rectangular parallelepiped shape, the remaining remaining ones. And forming an overlapping portion at least partially overlapping with the bottom plate of the base plate, and extending inward from a pair of corner portions arranged on one diagonal of the bottom surface of the storage box in the assembly posture on the two bottom plates. Each bending guide line is formed, and the two bottom plates are bent along the bending guide line by joining the overlapping portion to the adjacent bottom plate outside the bending guide line. A storage box that can be switched to a folding posture, wherein the first bottom plate that is disposed on the innermost side of the storage box in the assembly posture among the four bottom plates is formed to be substantially the same size as the bottom surface of the storage box, Folding posture from the assembly posture It is provided with a first regulating structure for regulating the rotation of the first bottom plate to.

  In this first storage box, the size of the first bottom plate disposed on the innermost side of the storage box is set to be approximately the same as the bottom surface of the storage box, and is stored in the storage box between the first bottom plate and the opening / closing lid. Since the contents are always arranged, even if the bottom plate is pushed inward, the upward movement of the contents is restricted by the opening / closing lid, and the rotation of the first bottom plate to the folding posture side is restricted. . In addition, since the entire bottom surface of the storage box is closed by the first bottom plate, it is difficult to put fingers between the first bottom plate and the side plates, so that the removal or replacement of the contents is effectively prevented. Furthermore, since the first restricting structure restricts the rotation of the first bottom plate to the folding posture side, it is effectively prevented that the bottom plate is pushed inward and the contents are removed or replaced. Become.

  Here, as a first embodiment of the first restricting structure, a standing upright along a second side plate provided at the free end portion of the first bottom plate so as to face the first side plate connected to the first bottom plate. It is preferable that a raised portion is formed, and an upper edge portion of the second side plate is folded inward to form a locking portion whose lower end portion engages with the upper end portion of the raised portion. Although it is possible to restrict the rotation of the first bottom plate by pressing a part of the first bottom plate against the inner surface of the side plate or the like, as in the present invention, the upper end portion of the rising portion and the lower end of the locking portion. When the rotation of the first bottom plate to the folding posture side is restricted by engaging the portion, the rotation of the first bottom plate to the folding posture side is effectively prevented without depending on frictional resistance or the like. be able to.

  As the first restricting structure in the first embodiment, it is possible to adopt a structure in which both of them are simply faced to each other, but a part or all of the upper end portion of the rising portion is fitted between the locking portion and the side plate. It can also be arranged so as to get stuck. When the upper end portion of the rising portion and the lower end portion of the locking portion are abutted, it is preferable that the locking portion is glued to the side plate. In other words, a force that attempts to spread outward due to the restoring force of the material acts on the standing part, but a force that attempts to spread inward due to the restoring force of the material acts on the locking part. It is preferable that the engaging portion is glued to the side plate so that the upper end portion is securely brought into contact with the lower end portion of the engaging portion. In the case where it is arranged so that part or all of the upper end portion of the raised portion fits between the locking portion and the side plate, a gap is formed between the lower end portion of the locking portion and the side plate, and the first bottom plate is folded. When it is turned to the tatami posture side, the raised portion is fitted between the locking portion and the side plate, and the first bottom plate is moved to the folding posture side only up to the higher height of the raised portion and the locking portion. When configured so that it does not rotate, or when at least one of the rising portion and the locking portion is formed in a wave shape and the first bottom plate is rotated to the folding posture side, the two mesh with each other. Can be configured.

  In the first embodiment, it is also preferable that at least one of the upper end portion of the rising portion and the lower end portion of the locking portion is formed in a wave shape. When one of the rising part or the locking part is formed in a wave shape, even if one wave of the corrugated part comes off the locking part or the rising part, the remaining wave and the locking part or the rising part Is maintained, so that the rotation of the first bottom plate toward the folding posture can be effectively prevented. Moreover, when it forms in the wave shape which mutually fits the upper end part of a standing part and the lower end part of a latching | locking part, while being able to obtain the effect | action similar to the above, it latches with the upper end part of a standing part. The contact area with the lower end part of the part can be increased, and the rotation of the first bottom plate to the folding posture side can be more effectively prevented.

  As a second embodiment of the first restricting structure, it is also preferable that a restricting piece that is pressed against the inner surface of the side plate in the assembly posture is formed on the side edge of the free end portion of the first bottom plate. In this case, the rotation of the first bottom plate toward the folding posture side can be restricted with a simple configuration.

  As a third embodiment of the first restricting structure, a restricting piece is formed on the side edge of the free end portion of the first bottom plate, and a slit for fitting the restricting piece is formed on the side plate facing the free end portion of the first bottom plate. Forming is also a preferred embodiment. In this case, the rotation of the first bottom plate to the folding posture side can be effectively prevented by the engagement between the restriction piece and the slit.

  In the second and third embodiments, an erecting portion that rises along a second side plate provided facing the first side plate that is continuous with the first bottom plate is formed at the free end of the first bottom plate. And a regulation piece can be provided in the side edge of a standing part. In particular, when the rotation of the first bottom plate to the folding posture side is restricted by the engagement between the restriction piece and the slit, when the first bottom plate is turned to the folding posture, in the in-plane direction of the restriction piece. On the other hand, since force acts on the restriction piece, it is possible to effectively prevent the restriction piece from falling off the slit due to deformation of the restriction piece.

  As 4th Embodiment of the said 1st control structure, the standing part which stands | stands up along the 2nd side plate provided in the free end part of a 1st bottom plate facing the 1st side plate connected with the 1st bottom plate is provided. It is also possible to form a restricting portion that engages with the lower end of the glue margin portion for joining the end portion of the side plate to the side edge of the raised portion. If comprised in this way, the existing glue margin part can be utilized effectively and the rotation to the folding attitude | position side of a 1st bottom board can be prevented effectively.

  In addition, the 1st control structure of the said 1st-4th embodiment can be used together combining arbitrarily.

  The second storage box according to the present invention includes four side plates and four bottom plates connected to the lower ends of the four side plates, and the remaining remaining adjacent to each other in the assembly posture in which the two bottom plates are assembled in a rectangular parallelepiped shape. And forming an overlapping portion at least partially overlapping with the bottom plate of the base plate, and extending inward from a pair of corner portions arranged on one diagonal of the bottom surface of the storage box in the assembly posture on the two bottom plates. Each bending guide line is formed, and the two bottom plates are bent along the bending guide line by joining the overlapping portion to the adjacent bottom plate outside the bending guide line. A storage box that can be switched to a folding posture, wherein the first bottom plate that is disposed on the innermost side of the storage box in the assembly posture among the four bottom plates is formed to be substantially the same size as the bottom surface of the storage box, Formed the bending guide line One of the bottom plate, engages in the assembled position, is provided with a second control structure consisting of the engaging portion which indirectly restrict the rotation of the folding position of the first bottom plate.

  In the second storage box, like the first storage box, the size of the first bottom plate disposed on the innermost side of the storage box is set to be approximately the same as the bottom surface of the storage box, and the first bottom plate Since the contents stored in the storage box are always placed between the opening and closing lid, even if the bottom plate is pushed inward, the upward movement of the contents is restricted by the opening and closing lid, and the first bottom plate is folded. The rotation to the posture side is restricted. In addition, since the entire bottom surface of the storage box is closed by the first bottom plate, it is difficult to put fingers between the first bottom plate and the side plates, so that the removal or replacement of the contents is effectively prevented. Further, a second restriction structure comprising an engaging portion that engages with the two bottom plates formed with the folding guide lines in the assembly posture and indirectly restricts the rotation of the first bottom plate to the folding posture side. Since the engaging portions of the two bottom plates that have formed the bending guide lines in the assembly posture are engaged with each other, the rotation of the two bottom plates to the folding posture side is restricted, and accordingly Since the rotation of the first bottom plate toward the folding posture side is indirectly restricted, it is effectively prevented that the bottom plate is pushed inward to extract or replace the contents.

  Here, in the 2nd storage box which concerns on this invention, it is preferable embodiment to provide the 1st control structure of any one of the said Claims 1-7. If comprised in this way, rotation to the folding attitude | position side of a 1st bottom board can be prevented more effectively by the 1st control structure and the 2nd control structure.

  According to the storage box according to the present invention, the first restriction of the rotation of the first bottom plate to the folding posture side is provided while the one-touch type storage box can be switched between the assembly posture and the folding posture with one touch. By restricting the structure and / or the second restriction structure so that the bottom plate does not easily lift up to the inside of the storage box, it is possible to effectively eliminate problems caused by extraction or replacement of the contents stored in the storage box. Can be prevented.

The side blades 4 and 5 are tilted inward, the opening / closing lid 6 is tilted forward, and the insertion piece 12 is inserted along the inner side of the front side plate 2F, so that the opening / closing lid 6 can be closed. Yes.

  A trapezoidal left bottom plate 3L is rotatably connected to the lower end of the left side plate 2L with a crease line L9 interposed therebetween, and a substantially L-shaped right bottom plate 3R with a crease line L10 interposed between the lower end of the right side plate 2R. A substantially L-shaped front bottom plate 3F is rotatably connected to the lower end of the front plate 2F with a fold line L11 interposed therebetween, and a fold line L12 is inserted to the lower end of the rear plate 2B. A rectangular rear bottom plate 3B (this corresponds to the first bottom plate) is connected in a freely rotatable manner. The crease lines L1 to L12 are formed in order to make it easy to bend the material sheet along the crease lines L1 to L12, and are formed by a well-known method such as molding a long and narrow groove into the material sheet or half-cutting the material sheet. Is formed. The same applies to crease lines L13 and L14 described later.

  The front bottom plate 3F is formed with a folding guide line 9 extending obliquely rearward from the left front end thereof at an inclination angle of about 45 ° with respect to the crease line L11, and the right bottom plate 3R is formed with a crease line L10 from the right rear end thereof. A bending guide line 10 extending obliquely forward at an inclination angle of about 45 ° is formed, and a bending guide line 13 extending obliquely forward from the right rear end portion is formed on the rear bottom plate 3B. The bending guide lines 9, 10, and 13 are formed by molding long strips into the material sheet or half-cutting the material sheet, and forming perforations or cuts at regular intervals in the middle of the material sheet. Thus, it is configured to bend more easily than the crease line L.

  On the left rear side of the bending guide line 9 of the front bottom plate 3F, a superposed portion 7 is formed so as to be superimposed on the lower side of the left bottom plate 3L, and an adhesive portion 14 indicated by hatching shown in FIG. The front bottom plate 3F and the left bottom plate 3L are stuck together by gluing to the sticking portion 15 of the left bottom plate 3L. On the left rear side of the bending guide line 10 of the right bottom plate 3R, a superposed portion 8 is formed so as to be superimposed on the lower side of the rear bottom plate 3B, and an adhesive portion 16 indicated by hatching shown in FIG. The right bottom plate 3 </ b> R and the rear bottom plate 3 </ b> B are bonded together by gluing to the bonding portion 17 of the rear bottom plate 3 </ b> B. The left bottom plate 3L and the front bottom plate 3F are disposed below the rear bottom plate 3B, and the right end portion of the front bottom plate 3F is inserted between the right bottom plate 3R and the rear bottom plate 3B, and along the bending guide lines 9 and 10 3F and the right bottom plate 3R are bent upward, and the bottom plates 3F, 3R, 3B, and 3L are bent along the crease lines L11, L10, L12, and L9 in conjunction with the 3F and the right bottom plate 3R. It is comprised so that an edge part may mutually be spaced apart and the storage box 1 may be folded in substantially flat form.

  The rear bottom plate 3B is set to be approximately the same size as the bottom surface of the storage box 1 in the assembly posture. The folding guide line 13 of the rear bottom plate 3B is formed by bending the rear bottom plate 3B along the folding guide line 13 when the storage box 1 is switched from the assembly posture to the folding posture or vice versa. Even when the right edge of the bottom plate 3B hits the inner surface of the right plate 2R, the storage box 1 can be easily switched in posture.

  According to the present invention, in the storage box 1 having the basic configuration as described above, the rear bottom plate 3B is rotated from the assembly posture to the folding posture side at the free end portion of the rear bottom plate 3B arranged on the innermost side of the storage box 1. The first restriction structure 20 for restriction is provided.

  As shown in FIGS. 1 to 3, the first restricting structure 20 </ b> A according to the first embodiment has a rising portion 21 that rises along the front side plate 2 </ b> F in the assembly posture as a front end portion (free end portion) of the rear bottom plate 3 </ b> B. Is formed with a crease line L13 sandwiched between them, and an engaging portion 22 is formed at the upper end of the front side plate 2F and folded back inward with the crease line L14 interposed therebetween. 22 is provided so as to be able to abut with substantially no gap.

  The raised portion 21 and the locking portion 22 are preferably provided over the entire length of the rear bottom plate 3B and the front side plate 2F, but may be provided partially. The height of the upright part 21 and the latching | locking part 22 can be set arbitrarily. The locking portion 22 is folded back to the inside of the front side plate 2F and glued to the front side plate 2F. Even when a large upward force is applied to push the rear bottom plate 3B in the assembly posture, the rising portion 21 is locked to the locking portion. 22 is configured so that the upward rotation of the rear bottom plate 3B is restricted. In addition, you may stick an adhesive tape over the standing part 21 and the latching | locking part 22 after the assembly of the storage box 1. FIG.

  In the storage box 1 provided with the first restricting structure 20A having such a configuration, when the rear bottom plate 3B is pushed upward while the contents are stored, the upper end portion of the rising portion 21 is engaged with the locking portion 22. Since the rotation of the rear bottom plate 3B to the folding posture side (upper side) is restricted, it is effective to push up the bottom plate 3 to extract or replace the contents of the storage box 1 Can be prevented. Moreover, since the rear bottom plate 3B is substantially the same size as the bottom surface of the storage box 1 in the assembly posture, it is difficult to insert a finger between the rear bottom plate 3B and the side plate 2, and the contents are also removed or replaced from this point. Can be effectively prevented. Furthermore, in a state in which the contents are loaded, the contents abut against the inner surface of the opening / closing lid 6 and the upward rotation of the rear bottom plate 3B is restricted, so that the contents can be prevented from being removed or replaced. become.

  In addition, when the clearance is formed between the lower end part of the latching | locking part 22 and the front side board 2F like the 1st control structure 20B shown in FIG. 4, and it is going to rotate the rear bottom board 3B to the folding attitude | position side, The rising portion 21 may be inserted between the locking portion 22 and the front side plate 2F. In this case, when the rear bottom plate 3B is pushed upward, the upright portion 21 needs to move upward while tearing the adhesive portion between the locking portion 22 and the front plate 2F, and the rear bottom plate 3B is folded. When the rotation to the posture side is restricted and the rising part 21 moves upward to the turning part 23 between the locking part 22 and the front side plate 2F, the upper end part of the rising part 21 is located inside the turning part 23. Since the abutting and the upward movement of the rear bottom plate 3B are restricted, it is possible to effectively prevent the contents from being extracted or replaced.

  Further, one of the upper end portion of the rising portion 21 and the lower end portion of the locking portion 22 in the first embodiment may be formed in a wave shape that alternately protrudes in the vertical direction. For example, like the first regulating structure 20C of the storage box 1C shown in FIGS. 5 and 6, a trapezoidal corrugated corrugated portion 24 is formed at the upper end portion of the rising portion 21C, and the upper end portion of each corrugated portion 24a is locked. It can comprise so that a slight clearance may be opened and the lower end part of the part 22 may face. In this case, for example, even if the engagement between one wave portion 24a and the locking portion 22 is disengaged, the engagement with the other locking portion 22 is maintained, so that the contents are removed or replaced. This can be prevented more effectively. Moreover, like the 1st control structure 20D of the storage box 1D shown in FIGS. 7-9, the semicircle part which protrudes to the upper side and the lower side is alternately formed in the upper end part of the standing part 21D, and the lower end part of the latching | locking part 22D. It is also possible to form the corrugated portions 25 and 26 connected to each other so that the corrugated portions 25 and 26 face each other with a slight gap. In this case, even if one of the wave portions 25a and 26a constituting both the waveform portions 25 and 26 is disengaged, the engagement of the other wave portions 25a and 26a is maintained, and the rising portion 21 and Since the contact area with the locking portion 22 can be set large, it is possible to more effectively prevent the contents from being extracted or replaced. Furthermore, it is also possible to form one of the upper end portion of the rising portion 21 and the lower end portion of the locking portion 22 in a wave shape set so that the amplitude is in the front-rear direction. In this case, even if the positional relationship in the front-rear direction between the upright portion 21 and the locking portion 22 is slightly deviated, it is preferable because the rotation of the rear bottom plate 3B to the folding posture side can be restricted.

  Furthermore, one of the upper end portion of the rising portion 21 and the lower end portion of the locking portion 22 is formed in a wave shape that alternately protrudes in the vertical direction and is formed in a wave shape that alternately protrudes in the front-rear direction. Or it can also comprise so that the corrugated part of the latching | locking part 22 may mesh with the straight part or corrugated part of the latching | locking part 22 or the standing part 21. FIG. For example, in the storage box 1 </ b> C shown in FIGS. 5 and 6, the wave portions 24 a of the corrugated portions 24 are alternately projected forward and backward, and the intermediate position in the front-rear direction of the wave portions 24 a that projects the lower end of the locking portion 22 forward and backward. When the rear bottom plate 3B is pushed upward, the locking portion 22 is engaged with the wave bottom of the wave portion 24a of the wave portion 24, and the upward movement of the rising portion 21 is restricted. You can also

  In the first restricting structure 20A, the locking portion 22 may be omitted, and the rising portion 21 may be extended to substantially the same height as the upper edge of the front side plate 2F. In this case, when the rear bottom plate 31B is pushed upward, the upper end portion of the rising portion 21 comes into contact with the opening / closing lid 6 and the rotation of the rear bottom plate 31B to the folding posture side is restricted. . Note that it is preferable that the rising portion 21 is positioned on the fold line L7 side of the opening / closing lid 6 because the upper end portion of the rising portion 21 becomes inconspicuous when the opening / closing lid 6 is opened.

  Next, the first restriction structures 20E to 20G of the second embodiment to the fourth embodiment will be described. The storage boxes 30E to 30G of the second embodiment to the fourth embodiment are the storage boxes 1 in the above example. Since the basic configuration is slightly different, the difference will be briefly described. However, since the basic configuration of the storage boxes 30E to 30G is the same, the basic configuration of the storage box 30E will be described. The same members as those in the above embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIGS. 10 and 11, the storage box 30E includes a left bottom plate 31L having the same shape as the right bottom plate 3R in the above-described embodiment, and the left-side plate 2L with a crease line L9 interposed therebetween. The right bottom plate 31R having the same shape as the left bottom plate 3L is connected to the right side plate 2R with the crease line L10 interposed therebetween, the rear bottom plate 31B having the same shape as the front bottom plate 3F in the above embodiment, and the crease line L12 to the rear side plate 2B. The front bottom plate 31F, which is connected continuously with the raised portion 21 omitted from the rear bottom plate 3B in the above-described embodiment, is connected to the front side plate 2F with the crease line L10 interposed therebetween, the locking portion 22 is omitted, and the first The first restricting structure 20E is provided in place of the restricting structure 20A, and the rest is configured in the same manner as in the above embodiment.

  The first regulating structure 20E of the storage box 30E of the second embodiment is substantially the same as the bottom surface of the storage box 1 in the assembly posture with the front bottom plate 31F (corresponding to the first bottom plate) as shown in FIGS. The regulating pieces 33 are formed in a protruding shape on the left and right side edges of the free end portion of the front bottom plate 31F so as to be pressed against the inner surfaces of the left and right side plates 2L and 2R in the assembly posture.

  The protruding length and width of the restricting piece 33 can be arbitrarily set. However, if the length is too large, the switching operability of the storage box 1 from the folding position to the assembly position is lowered, and if too small, the front bottom plate 31F toward the folding position is reduced. Therefore, the projection length is set to 0.5 mm to 5 mm, preferably 1 mm to 3 mm, and the length is set to 3 mm to 20 mm, preferably 5 mm to 15 mm. . Moreover, it is preferable to provide the restricting piece 33 on both the left and right sides of the free end portion of the front bottom plate 31F, but it is also possible to provide the restriction piece 33 only on one side, or the free end of the front bottom plate 31F so as to protrude rearward in the assembly posture. It is also possible to configure so as to be in pressure contact with the inner surface of the rear side plate 2B, and to use both a restriction piece protruding to the left and right sides of the front bottom plate 31F and a restriction piece protruding rearward from the free end portion It is also possible to do.

  As shown in FIGS. 12 to 14, the first regulating structure 20F of the storage box 30F of the third embodiment is arranged on the inner surface of the rear side plate 2B in the assembly posture with the fold line L13 sandwiched between the free end portion of the front bottom plate 31F. A rising portion 21F extending upward along the left and right side edges of the rising portion 21F is formed in a protruding shape, and a fold line L1 between the rear side plate 2B and the left and right side plates 2 is formed. The slit 36 is formed in the vicinity of L2, and the restricting piece 35 is fitted into the slit 36 in the assembly posture, thereby restricting the front bottom plate 31F from rotating upward in the assembly posture of the storage box 1. Is.

  The protruding length and height of the restricting piece 35 can be set arbitrarily. However, if it is too large, the switching operability of the storage box 1 from the folding position to the assembled position is lowered, and if it is too small, the restricting piece 35 falls off the slit 36. Since the rotation of the front bottom plate 31F to the folding posture side cannot be sufficiently controlled, the protruding length is set to 0.5 mm to 5 mm, preferably 1 mm to 3 mm, and the height is 3 mm to mm to 15 mm. Preferably, it is set to 5 mm to 10 mm.
