In addition, as shown in FIG. 7, a guide protrusion 46 is provided that protrudes downward from the lower surface of the bottom of the release member insertion portion 45, and when the lock member 21 slides, the guided protrusion of the lock member 21 28 is in sliding contact with the guide protrusion 46, so that the direction of sliding displacement is guided. Further, as shown in FIG. 12, the width of the operating portion 25 in the direction orthogonal to the sliding direction of the locking member 21 is configured to be slightly shorter than the width of the short side of the locking member accommodating portion 32. During sliding displacement, the side portion of the operating portion 25 comes into sliding contact with the side portion of the locking member accommodating portion 32, so that the sliding displacement is guided.

As shown in FIGS. 7, 12, and 18, a through hole 47 communicating with the locking member accommodating portion 32 is provided at the bottom of the release member insertion portion 45. As shown in FIGS. In this embodiment, a pair of through holes 47 are provided in each release member insertion portion 45 in correspondence with a pair of locking portions 23 of each lock member 21 . As shown in FIG. 19 etc., the pair of contact parts 43 of the release member 41 can be inserted into the pair of through holes 47 of the release member insertion part 45, and the depth of the through hole 47 (the depth of the release member insertion part 45) The length is longer than the thickness of the bottom.

Furthermore, as shown in FIG. 14, when the lock member 21 is in the locked state and the locking part 23 is in the locked state, the outside of the container 1 (the top surface of the second lid body 3b in the closed position) The locking protrusion 27 (upper surface of the locking protrusion 27) is configured to be visible from the side) through the through hole 47 (in plan view, the formation range of the through hole 47 and the locking protrusion 27 are installed). (overlapping the location). Therefore, as shown in FIG. 19 etc., by inserting the release member 41 into the release member insertion portion 45 so that the contact portion 43 is inserted into the through hole 47, the tip of the contact portion 43 can be It comes into contact with the locking protrusion 27 of the locking portion 23.

As shown in FIGS. 3, 18, etc., the locking protrusion 27 is located on the upper surface that is visible through the through hole 47, and is located at the front end of the release member 41 in the insertion direction of the abutting portion 43 into the through hole 47. A release slope portion 48 that slopes in a direction away from the displacement direction toward the side where the locking state of the locking portion 23 (locking piece 26) is released (in this example, the direction approaching the extension portion 24). It is equipped with Furthermore, as shown in FIGS. 6, 19, etc., the contact portion 43 extends in a direction substantially parallel to the release slope portion 48 at a position where it can contact the release slope portion 48 when inserted into the through hole 47. The contact portion slope portion 49 is provided. Therefore, by inserting the abutting part 43 into the through hole 47, the abutting part inclined part 49 of the abutting part 43 and the release inclined part 48 of the locking protrusion 27 come into contact with each other, and the release is continued as it is. By pushing the member 41 in a direction (downward) substantially perpendicular to the sliding direction of the locking member 21, the locking portion 23 (locking piece 26) is moved between the release inclined portion 48 and the locking piece 26, as shown in FIG. It is guided by the contact part inclined part 49 and is displaced (elastically deformed) toward the extension part 24 . As a result, the locking protrusion 27 is displaced and the locking state of the locking part 23 and the locked part 35 is released, and as shown in FIG. 25 to slide the lock member 21 toward the center in the width direction of the second lid body 3b, the lock member 21 is brought into an unlocked state. Furthermore, when the locking member 21 is in the unlocked state, the locking portion 23 returns to its original linearly extending state based on its own elasticity, and when the locking member 21 is displaced toward the locked state, The locking protrusion 27 comes into contact with the unlock restricting portion 37, and further displacement toward the locked state is inhibited (see FIG. 12).

Note that, as shown in FIG. 3 and the like, the locking portion 23 has a thick portion at the tip end side in the protruding direction including the locking protrusion 27. Furthermore, as shown in FIG. 18 and the like, the tip of the locking protrusion 27 in the direction of protrusion from the locking piece 26 is not only the inclined part that is the releasing slope part 48, but also the tip of the locking protrusion 27 when the second lid body 3b is in the closed position. In some cases, it also includes a portion extending substantially vertically. In addition, as shown in FIGS. 12 and 14, the operating portion 25 of the locking member 21 can be operated by an operator even when the locking member 21 is in the locked state or the unlocked state. The locking member 21 is exposed to the outside, and the operating portion 25 is operated when the locking member 21 is displaced.

Further, as shown in FIGS. 7, 14, etc., the release member insertion portion 45 includes a protrusion 50 that protrudes from the edge of the through hole 47 to the inside of the through hole 47. As shown in FIGS. On the other hand, as shown in FIGS. 6, 19, etc., the contact portion 43 is provided with a groove portion 51 into which the protrusion 50 is allowed to be inserted when the contact portion 43 is inserted into the through hole 47. There is. That is, by aligning the positions of the protrusion 50 and the groove 51, the contact portion 43 can be inserted into the through hole 47.

In addition, as shown in FIG. 19 etc., in this embodiment, the locking part 23 is brought into contact with the bottom of the locking member accommodating part 32 together with the extension part 24, and the locking part 23 is in contact with the bottom of the locking member accommodating part 32, and In the state in which the abutting portion 43 is pressed, downward deformation of the locking portion 23 is restricted by the bottom of the locking member accommodating portion 32 . Further, as shown in FIG. 20 and the like, an opening is formed at the bottom of the locking member accommodating portion 32, into which the tip of the abutting portion 43 of the release member 41 can be inserted when the locking member 21 is in the locked state. . This allows the portion of the inner surface of the contact portion 43 where the contact portion inclined portion 49 is not formed to come into contact with the tip of the locking protrusion 27 in the direction of protrusion from the locking piece 26. Therefore, the locking portion 23 can be elastically deformed more reliably. Furthermore, in this embodiment, when the lock member 21 is in the locked state, the guided protrusion 28 and the guide protrusion 46 are locked between the pair of locking parts 23 (locking protrusions 27) of the locking member 21. It is configured to extend along the sliding displacement direction of the member 21 (width direction of the second lid body 3b), and even when the locking portion 23 is elastically deformed, the locking member 21 is configured to extend along the sliding displacement direction. Displacement (slip) in a direction perpendicular to the direction is restricted.

As described in detail above, according to the present embodiment, by using the dedicated release member 41 when the lock member 21 is brought into the unlocked state, the locking portion 23 and the locked portion 35 are connected to the container. The container 1 can be arranged so that it cannot be accessed or is difficult to contact from the outside, and a person other than the party who does not own the dedicated release member 41 can unlock the lock member 21 to change the shape of the container 1. (opening of the sealed container 1) can be prevented. Therefore, for example, it is possible to prevent a situation where the container 1 is illegally opened during transportation and the contents are looked into or taken out, and it is possible to provide the container 1 with high security performance. As a result, it is possible to prevent a situation in which the container 1 is changed from its intended form by a person other than the person concerned, and it is possible to more appropriately transport, store, etc. the goods between the parties. Note that the locking member 21 is held by the holding portion 31 even in the unlocked state, and when locking with the locking member 21 is performed, it is possible to save the effort of preparing the locking member 21 one by one.

In addition, the locking protrusion 27 and the locked portion 35 are provided with lock regulating surfaces 36 that face each other when the locking member 21 is in the locked state and are capable of abutting (flat) surfaces. Therefore, the locked state of the locking member 21 can be stabilized. Further, by providing the unlocking regulating portion 37 in the holding portion 31 (locking member accommodating portion 32), the unlocked state of the locking member 21 is stabilized (the locking member 21 is inadvertently moved to the locked state side). can be prevented from being displaced). Further, the part that the unlock regulating part 37 comes into contact with when regulating the displacement of the locking member 21 in the unlocked state toward the locked state is the locking protrusion 27 , and the part that is provided on the locking protrusion 27 is the locking protrusion 27 . The guide inclined portion 38 comes into pressure contact with the unlock regulating portion 37, thereby promoting elastic deformation of the locking portion 23 (locking piece 26), and the elastic deformation of the locking portion 23 causes the unlock regulating portion 37 to control the state. is resolved. Therefore, when an operator intends to displace the lock member 21 in the unlocked state toward the locked state, the worker can move the lock member 21 toward the locked state by simply pushing the lock member 21 toward the locked state. , it is possible to improve workability when locking the locking member 21.

Further, the locking member 21 is configured to be slid in the width direction (axial direction) of the second lid body 3b, and the locking member 21 includes an operating portion 25 that is operated when the locking member 21 is displaced, and a releasing member. 41 is configured to be pushed in a direction substantially perpendicular to the displacement direction of the locking member 21 when the locking portion 23 is released from the locked state. Therefore, while releasing the locking state of the locking portion 23 by the release member 41, the operating portion 25 can be operated to displace the lock member 21 in the locked state to the unlocked state side. Therefore, it is possible to improve the workability when bringing the locking member 21 into the unlocked state.

Further, the release member insertion portion 45 overlaps a part of the lock member accommodating portion 32 (the range where the locking portion 23 etc. are arranged when the lock member 21 is in the locked state) on the outer side (upper side) of the container 1. A through hole 47 is provided at the bottom of the release member insertion portion 45 and communicates with the lock member accommodating portion 32 and into which the abutting portion 43 of the release member 41 is inserted. Therefore, the locking part 23 in the locked state is placed in a position where it is difficult to contact from the outside of the container 1, and the contact part 43 of the release member 41 is brought into contact with the locking part 23. can be released from the locked state. Further, when inserting the release member 41 into the release member insertion portion 45 to release the locked state of the locking portion 23, and furthermore, when inserting the contact portion 43 of the release member 41 into the through hole 47, the release member insertion The posture of the release member 41 can be guided (suppressed from falling) by the side portions of the portion 45 . Therefore, the locking state of the locking portion 23 can be released more accurately and smoothly while ensuring security performance.

Further, the locking protrusion 27 of the locking portion 23 has a side on which the locking state of the locking piece 26 is released toward the front side in the insertion direction of the contact portion 43 of the release member 41 into the through hole 47. A releasing inclined part 48 is provided which is inclined in a direction away from the displacement direction, and when the locking member 21 is in the locked state and the locking part 23 is in the locked state, the through hole 47 can be opened from the outside of the container 1. The release slope portion 48 is configured to be visible through the opening. That is, when releasing the locked state of the locking part 23, the contact part 43 can be brought into contact with the releasing inclined part 48 by inserting the contact part 43 of the release member 41 into the through hole 47. Furthermore, by bringing the abutting portion 43 into pressure contact with the releasing inclined portion 48, the locking portion 23 can be elastically deformed more accurately and smoothly due to the inclination of the releasing inclined portion 48. Therefore, the work of releasing the locked state of the locking portion 23 can be performed more suitably.

In addition, the contact portion 43 includes a contact portion slope portion 49 extending in a direction substantially parallel to the release slope portion 48 at a position where the contact portion 43 can contact the release slope portion 48 when inserted into the through hole 47. ing. Thereby, elastic deformation of the locking portion 23 when releasing the locked state of the locking portion 23 can be assisted more reliably. Furthermore, the area in which the contact part 43 and the locking part 23 contact can be increased, and when the contact part 43 and the locking part 23 contact each other, the contact part 43 and the locking part 23 are not damaged. Such situations can be prevented.

Further, the release member insertion portion 45 includes a protrusion 50 that projects from the edge of the through hole 47 to the inside of the through hole 47, and the abutment portion 43 of the release member 41 has a protrusion 50 that extends from the edge of the through hole 47. A groove 51 into which the protrusion 50 is inserted is provided. With this configuration, when the abutting part 43 is inserted into the through hole, the protrusion 50 can guide the position and posture of the abutting part 43 (suppressing falling down). Therefore, it is possible to improve the workability of releasing the locked state of the locking portion 23. Furthermore, by providing a plurality of shapes and arrangement patterns of the protrusions 50 and grooves 51, it is possible to improve security performance and convenience (for example, to accommodate multiple customers individually). can. Furthermore, the through hole 47 is narrowed by the protrusion 50, and the action of inserting a jig other than the release member 41 into the through hole 47 to release the locked state of the locking portion 23 is more reliably inhibited. Can be done. Therefore, it is possible to make it more difficult to release the locked state of the locking portion 23 with anything other than the release member 41, and the security performance can be further improved.

It can also be used as the main body. Moreover, it is also possible to embody the container in which the entire container body is integrally formed. Furthermore, it is also possible to embody a container in which at least one of the side walls is detachably attached to the bottom wall component.

In addition, the lid is omitted (instead of the upper part of the container body being closed), and an opening is provided in a predetermined side wall, and a door is provided to open and close the opening, and a door that opens and closes the opening is provided. It is also possible to implement the container with a locking member that maintains its condition. In this case, the container body and the door constitute container components. That is, the object whose displacement is regulated by the lock member 21 and whose restricted state is released by the dedicated release member 41 is not limited to the door body 3, but also the opening and closing of the lid body and the door body, the assembly of the container body, and the like. Concerning a container whose form can be changed, such as by folding, change from a predetermined form can be regulated (a predetermined container constituent member in a predetermined form and a container constituent member adjacent to the predetermined container constituent member) It may also be configured to include a locking member (capable of regulating relative displacement) and a release member capable of releasing the regulation state by the locking member. By adopting this configuration, the container may be changed from its intended form by someone other than the person concerned (for example, if a door body is provided on the side wall, the door body may be opened inadvertently and the contents may be damaged). It is possible to prevent situations such as items being washed away, and it is possible to more appropriately transport and store items between the parties. Note that which form of the container is maintained by the locking member can be changed as appropriate; for example, the locking member may maintain the assembled state of the container body 2 or maintain the folded state of the container main body 2. It may be configured to do so. Furthermore, how the predetermined form of the container is maintained by the lock member can be changed as appropriate. For example, in order to maintain the assembled state of the container body 2, the short side side wall portion 6 and the bottom wall forming portion A lock member may be provided to restrict relative displacement between the short side side wall portion 6 and the long side side wall portion 5. Furthermore, locking members are provided to maintain a plurality of different configurations in one container (for example, a locking member 21 that maintains the configuration in which the lid 3 is placed over the container body 2, and a locking member 21 that maintains the configuration in which the lid 3 is placed over the container body 2, and a locking member 21 that maintains the configuration in which the container body 2 is in a folded state) are provided. It is also possible to provide a locking member that maintains this configuration.

In addition, in the above embodiment, the container 1 is made of polypropylene, but it may be made of other resin materials such as polyethylene, PET, and polyamide.

Alternatively, the clasp 13 may be omitted and one can be placed in the open position while the other is in the closed position from either side of the first lid 3a and the second lid 3b (in this case, For example, one locking member may be provided on each of the first lid and the second lid), or the outer size and shape may be approximately the same as the container body 2 in plan view (the opening of the container body 2 may be (having a shape that covers the entire container body 2), it may also be a lid body that is detachable from the container body 2. In addition, although the lid 3 for closing the opening of the container body 2 is composed of two lids, the first lid 3a and the second lid 3b in the above embodiment, it covers the entire opening. It may be composed of one, or it may be composed of three or more that share and cover the opening.

(c) In the above embodiment, one locking member 21 is provided with two locking portions 23, but the number of locking portions 23 may be one. However, when a plurality of locking portions 23 are provided in one locking member 21, it is more difficult to release all the locking portions 23 unless a dedicated release member 41 is used. As a result, security performance can be further improved, and the shapes and arrangement patterns of the protrusions 50 and grooves 51 can be made more diverse.

Further, in the above embodiment, the locking member 21 is provided so as to be slidably displaceable along the width direction (axial direction) of the second lid 3b, but may be configured to be rotatably displaceable. For example, a portion near one short side of a substantially rectangular plate-shaped locking member is pivoted to the second lid 3b such that the thickness direction of the second lid 3b is in the axial direction, and the locking member is With the displacement, the state of the locking member including the other short side changes between a state where it is engaged with the locked portion 34 of the short side frame component 7b and a state where the engaged state is released. A locking portion is provided on the one short side of the locking member, and the locking portion is locked to a locked portion provided on the second lid body when the locking member is in a locked state, and is released. The locking state may be released by elastically deforming the locking portion (by displacing the lock regulating surface) using the member (by pushing the release member in the direction of the rotational axis of the locking member).

Further, in the above embodiment, the locking portion 23 is configured to be elastically deformable with the locking piece 26 and the locking protrusion 27, but instead of this configuration, the locked portion 35 is configured to be elastically deformable. It may also be configured to be elastically deformable by having a locking protrusion. In addition, the lock member 21 is displaced to the unlocked state simply by inserting the release member 41 into the release member insertion portion 45 (for example, the locking portion protrudes from the operating portion toward the lock portion, and the abutment portion When the locking portion is pressed, the locking portion may be elastically deformed toward the extension portion and also pushed toward the unlocked state. Further, it may be configured such that when the locking member 21 is in the locked state, the locking member 21 cannot come into contact with the operating portion 25, or it becomes difficult to come into contact with the operating portion 25.

In addition, in the above embodiment, when releasing the locked state of the locking member 21 (releasing the locked state of the locking portion 23), the release member 41 is moved relative to the release member insertion portion 45 in the direction of displacement of the locking member 21. However, the direction in which the release member 41 is pushed is, for example, the direction in which the lock member 21 is displaced. (the side that is in the locked state or the side that is in the unlocked state), or a direction that intersects with the direction of displacement of the locking member 21, including a direction that is substantially orthogonal to the direction of displacement of the locking member 21. (oblique direction). Further, in the above embodiment, the release member insertion part 45 is omitted, and when releasing the locked state of the lock member 21, from the outside of the lid 3 (second lid 3b) (the lock member 21 is placed in a container different from the lid 3). In a modified example in which the release member 41 is attached to a component, the release member 41 may be pushed in from the outside of the container component.
