A storage container is used. For example, Patent Literature 1 describes a substrate storage container that includes a container body that stores a plurality of substrates and a lid that closes an opening of the container body.

JP 2015-162476 A

In the substrate storage container described in Patent Document 1, a gasket is provided on the periphery of the lid to improve sealing performance, and a retainer is provided on the rear surface of the lid to restrict movement of the substrate in the front-rear direction. ing. The gasket and retainer have different shapes. Therefore, since the gasket and the retainer are respectively prepared in the manufacturing process of the substrate storage container, the manufacturing takes time.

The present disclosure describes a panel container that can be simplified to manufacture.

A panel storage container according to one aspect of the present disclosure includes a container body that has an opening and stores a plurality of panels, and a lid that closes the opening. The lid body is provided in the lid body facing the plurality of panels housed in the container body in the first direction in a state where the lid body closes the opening, and the lid body is provided to provide a space between the lid body and the container body. A sealing member that seals, and a retainer that is provided on the lid body and restricts movement of the plurality of panels in the first direction. The sealing member is an elastic member that extends with a uniform cross-sectional shape. A retainer is an elastic member that extends with a uniform cross-sectional shape. The cross-sectional shape of the retainer is the same as the cross-sectional shape of the sealing member. The constituent material of the retainer is the same as that of the sealing member.

In this panel storage container, the lid body is provided with a sealing member and a retainer. The cross-sectional shape of the retainer is the same as the cross-sectional shape of the sealing member, and the constituent material of the retainer is the same as the constituent material of the sealing member. Therefore, since one type of elastic member can be used as the sealing member and the retainer, there is no need to prepare an elastic member for the sealing member and an elastic member for the retainer. In this way, the elastic member can be shared by the sealing member and the retainer, so that it is possible to simplify the manufacture of the panel storage container.

A panel storage container according to another aspect of the present disclosure includes a container body that has an opening and stores a plurality of panels, and a lid that closes the opening. The lid body is provided in the lid body facing the plurality of panels housed in the container body in the first direction in a state where the lid body closes the opening, and the lid body is provided to provide a space between the lid body and the container body. A sealing member that seals, and a retainer that is provided on the lid body and restricts movement of the plurality of panels in the first direction. The sealing member is an elastic member that extends with a uniform cross-sectional shape. A retainer is an elastic member that extends with a uniform cross-sectional shape. The cross-sectional shape of the retainer is the same as the cross-sectional shape of the sealing member.

In this panel storage container, the lid body is provided with a sealing member and a retainer. The cross-sectional shape of the retainer is the same as the cross-sectional shape of the sealing member. Therefore, since a common mold can be used as a mold for manufacturing the sealing member and the retainer, there is no need to prepare a mold for the sealing member and a mold for the retainer. In this way, the mold can be shared by the sealing member and the retainer, so that it is possible to simplify the manufacture of the panel storage container.

A panel storage container according to still another aspect of the present disclosure includes a container body having an opening for storing a plurality of panels, and a lid for closing the opening. The lid body is provided in the lid body facing the plurality of panels housed in the container body in the first direction in a state where the lid body closes the opening, and the lid body is provided to provide a space between the lid body and the container body. A sealing member that seals, and a retainer that is provided on the lid body and restricts movement of the plurality of panels in the first direction. The sealing member is an elastic member that extends with a uniform cross-sectional shape. A retainer is an elastic member that extends with a uniform cross-sectional shape. The constituent material of the retainer is the same as that of the sealing member.

In this panel storage container, the lid body is provided with a sealing member and a retainer. The constituent material of the retainer is the same as that of the sealing member. Therefore, since the sealing member and the retainer can be manufactured using one type of material, there is no need to prepare a material for the sealing member and a material for the retainer. In this way, the sealing member and the retainer can share the same constituent material, so that it is possible to simplify the manufacture of the panel storage container.

In some embodiments, the container body may accommodate a plurality of panels arranged in a second direction intersecting the first direction. The retainer may include a first restricting portion and a second restricting portion facing the plurality of panels in the first direction in a state where the lid closes the opening. The first restricting portion and the second restricting portion may extend in the second direction and be arranged in parallel in a third direction intersecting the first direction and the second direction. In this case, the first restricting portion and the second restricting portion face each panel in the first direction while the lid closes the opening. Therefore, since each panel is restricted from moving in the first direction at two locations, it is possible to more reliably restrict movement of each panel in the first direction.

In some embodiments, the lid body may include a first end and a second end, which are both ends in the third direction. The first restricting portion may be provided at the first end, and the second restricting portion may be provided at the second end. In this case, the first restricting portion and the second restricting portion face the vicinity of both ends of each panel in the first direction while the lid closes the opening. Therefore, since each panel is restricted from moving in the first direction at both ends thereof, it is possible to more reliably restrict movement of each panel in the first direction.

In some embodiments, the retainer may further include a third restricting portion extending in the second direction and provided between the first restricting portion and the second restricting portion in the third direction. In this case, in a state in which the lid blocks the opening, in addition to the first restricting portion and the second restricting portion, the third restricting portion faces each panel in the first direction. Therefore, since each panel is restricted from moving in the first direction at three points, it is possible to more reliably restrict movement of each panel in the first direction.

In some embodiments, the retainer may further include a first connecting portion that connects one end of the first restricting portion and one end of the second restricting portion. For example, the retainer is attached to the lid body with one end of the retainer as a reference. For this reason, if the length of the retainer is not as designed, excess or deficiency may occur at the other end of the retainer. If the retainer includes multiple physically spaced portions, there may be excess or deficiency at the ends of each portion. In the above configuration, the retainer is a member that continues in the order of the first restricting portion, the first connecting portion, and the second restricting portion. The number of ends can be reduced. Therefore, it is possible to reduce the possibility that the number of retainers is excessive or insufficient.

In some embodiments, the retainer may further include a second connecting portion that connects the other end of the first restricting portion and the other end of the second restricting portion. In this case, the retainer has an annular shape that circulates in the order of the first restricting portion, the first connecting portion, the second restricting portion, and the second connecting portion. Therefore, since the retainer has an endless shape, it is possible to eliminate excess or deficiency of the retainer at the ends.

In some embodiments, the lid body may comprise a first mounting portion for mounting the sealing member and a second mounting portion for mounting the retainer. In this case, the sealing member and the retainer can be attached to the lid body by the first attachment portion and the second attachment portion.

In some embodiments, the first attachment portion may have a dovetail structure. In this case, the sealing member is attached to the lid body simply by fitting the sealing member into the first attachment portion. Therefore, it is possible to simplify the attachment of the sealing member.

In some embodiments, the second attachment portion may have a dovetail structure. In this case, the retainer is attached to the lid body simply by fitting the retainer into the second attachment portion. Therefore, attachment of the retainer can be simplified.

In some embodiments, the lid body may further include a first cushioning material provided between the sealing member and the lid body and having a hardness lower than that of the sealing member. In this case, since the sealing member is less likely to deform than the first cushioning material, the sealing surface of the sealing member can be flattened. When locking the lid, the first cushioning material is crushed, thereby suppressing an increase in latch torque. Therefore, it is possible to reduce the possibility of creating a gap between the sealing member and the container body, and to more reliably lock the lid. As a result, it is possible to improve the airtightness of the panel container.

In some embodiments, the lid body may further include a second cushioning material provided between the retainer and the lid body and having a hardness lower than that of the retainer. In this case, since the retainer is less likely to deform than the second cushioning material, the surface of the retainer facing the panel can be flattened. When the panel comes into contact with the retainer, the second cushioning material is crushed, thereby suppressing excessive force from being applied to the panel. Therefore, it is possible to more reliably restrict the movement of each panel and reduce the possibility of damage to the panel.

According to the present disclosure, manufacturing of the panel container can be simplified.

An insertion hole that penetrates the support 65 in the front-rear direction is provided at the tip portion of the support 65, and the shaft 62a is inserted through the insertion hole. The support 65 has an inclined surface that slopes downward from the proximal end of the support 65 toward the distal end.

A proximal end portion of the support 65 is brought into contact with the inner surface of the side wall 23, and the side plate 28, the side wall 23, and the support 65 are positioned by knock pins (not shown). In this state, a screw is inserted from the outside of the side plate 28 into an insertion hole provided in the side plate 28 and screwed into a screw hole provided in the base end portion of the support 65 . As a result, the support 65 is fixed to the side plate 28 with the side wall 23 sandwiched between the support 65 and the side plate 28 .

The stopper 63 is a member for preventing the panel from popping out and for determining the position of the front end of the panel. The stopper 63 is made of, for example, the resin material described above. The stopper 63 is provided at the end 62d of the shaft 62a. For example, the stopper 63 is attached to the shaft 62a by fitting the end portion 62d of the shaft 62a into an attachment hole provided in the stopper 63 . The stopper 63 has a disk-shaped locking piece 63a having an outer diameter larger than that of the elastic body 62b. The locking piece 63a has an inclined surface that is inclined rearward from the outer peripheral surface toward the center.

The stopper 64 is a member for determining the position of the rear end of the panel. The stopper 64 is made of, for example, the resin material described above. The stopper 64 is provided at the end 62c of the shaft 62a. The stopper 64 has a block-like shape. The stopper 64 is provided with an insertion hole for inserting the shaft 62a in the front-rear direction. With the shaft 62a inserted through the insertion hole of the stopper 64, the rear surface of the stopper 64 is brought into contact with the front surface of the column 26c, and the stopper 64 is fixed to the column 26c by screws. The stopper 64 has an inclined surface that slopes forward as it goes downward from the upper surface.

A mounting position where the panel is mounted is defined by the stopper 63, the stopper 64, and the support 65. As shown in FIG. Specifically, the stoppers 63 and 64 define the mounting position of the panel in the front-rear direction, and the four supports 65 provided on the left and right define the mounting position of the panel in the left-right direction. For example, the panel is carried into the storage space 20 by a robot and placed on one of the storage stages. At this time, the position of the panel may be slightly shifted due to an error or the like. For example, even if the front end of the panel rides on the inclined surface of the locking piece 63a of the stopper 63, the weight of the panel guides the panel to the mounting position along the inclined surface. Similarly, even if the rear end of the panel rides on the inclined surface of the stopper 64, the weight of the panel itself guides it to the mounting position along the inclined surface. Similarly, even if the side edge of the panel rides on the inclined surface of the support 65, the weight of the panel itself guides the panel to the mounting position along the inclined surface.

The pair of locking pieces 36b are provided at the tips of the pair of side walls that define the groove 36a. Each of the pair of locking pieces 36b protrudes toward the other locking piece 36b. Each of the pair of locking pieces 36b has an inclined surface that is inclined so as to approach the other locking piece 36b from the groove 36a toward the rear surface 31b. The mounting portion 36 includes a missing portion 36c in which the locking piece 36b is not provided in a portion of the groove portion 36a. In this embodiment, the mounting portion 36 includes one missing portion 36c in each groove portion 36a.

The locking mechanism 32 locks or unlocks the lid 3 by operating a key inserted into the keyhole 31h. The locking mechanism 32 has a latch (not shown). With the lid 3 attached to the flange 25, the lid 3 is locked when the latch is fitted into the locking hole 25h provided in the flange 25 by operating the key. With the lid 3 locked, the lid 3 is unlocked by operating the key to pull out the latch from the locking hole 25h.

The sealing member 33 is a member that seals between the container body 2 and the lid body 31 . The sealing member 33 is a string-like elastic member extending with a uniform cross-sectional shape. In this embodiment, the sealing member 33 extends in a rectangular annular shape, and the cross-sectional shape of the sealing member 33 is an annular shape. That is, a tubular elastic member (for example, a rubber tube) is used as the sealing member 33 . The sealing member 33 is made of an elastically deformable resin having a durometer hardness (Shore A) of about 20 degrees to 80 degrees. Examples of such resins include fluororubbers, EPDM, silicones, and urethanes. The sealing member 33 is, for example, a gasket. The durometer hardness (Shore A) is determined according to JIS K6253.

The sealing member 33 is provided on the lid body 31 . In this embodiment, the sealing member 33 is attached to the lid body 31 by the attachment portion 35 . Specifically, the sealing member 33 is provided along the groove portion 35a and held in the groove portion 35a by a pair of locking pieces 35b. The diameter of the sealing member 33 is greater than the depth of the groove 35a. Therefore, the sealing member 33 is held by the mounting portion 35 with a portion of the sealing member 33 exposed (protruded) from the pair of locking pieces 35b. A surface exposed from the pair of locking pieces 35b functions as a sealing surface 33a. The opening 2a of the container body 2 is airtightly closed by pressing the sealing surface 33a against the container body 2 (flange 25).

The retainer 34 is a member that restricts movement of the panels housed in the container body 2 in the front-rear direction (movement toward the lid body 3). The retainer 34 is a string-like elastic member extending with a uniform cross-sectional shape. The cross-sectional shape of the retainer 34 is the same as the cross-sectional shape of the sealing member 33 . The constituent material of the retainer 34 is the same as the constituent material of the sealing member 33 .

The retainer 34 is provided on the lid body 31 . In this embodiment, the retainer 34 is attached to the lid body 31 by the attachment portion 36 . Specifically, the retainer 34 is provided along the groove portion 36a and is held in the groove portion 36a by a pair of locking pieces 36b. The diameter of retainer 34 is greater than the depth of groove 36a. Therefore, the retainer 34 is held by the mounting portion 36 with a portion of the retainer 34 exposed (protruding) from the pair of locking pieces 36b. The surface of the portion exposed from the pair of locking pieces 36b functions as the contact surface 34a. The forward movement of each panel is restricted by the contact surface 34a coming into contact with the front end of each panel.

The retainer 34 includes a restricting portion 41 (first restricting portion), a restricting portion 42 (second restricting portion), and a restricting portion 43 (third restricting portion). Each of the restricting portions 41 to 43 is a portion extending in the vertical direction. The restricting portion 41 is provided at one end 31c (first end), and the restricting portion 42 is provided at the other end 31c (second end). The restricting portion 43 is provided in the central portion 31d. In other words, the regulating portion 41, the regulating portion 43, and the regulating portion 42 are arranged in that order in the left-right direction and arranged substantially parallel to each other. That is, the restricting portion 41, the restricting portion 42, and the restricting portion 43 are arranged side by side in the lateral direction, and the restricting portion 43 is provided between the restricting portion 41 and the restricting portion 42 in the lateral direction.

When the lid 3 closes the opening 2a in a state in which a plurality of panels are accommodated in the container body 2, the sealing surface 33a of the sealing member 33 contacts the flange 25 and the contact surfaces of the restricting portions 41 to 43. 34a faces the front edge of each panel. Specifically, the contact surfaces 34a of the restricting portions 41 and 42 face the vicinity of both ends of the front end of each panel in the left-right direction, and the contact surface 34a of the restricting portion 43 faces the vicinity of the center of the front end of each panel in the left-right direction. . By locking the lid 3, the sealing member 33 (seal surface 33a) is pressed against the flange 25, and the contact surfaces 34a of the restricting portions 41 to 43 contact the front ends of the respective panels. As a result, the opening 2a of the container body 2 is airtightly closed, and the forward movement of the panel placed at the placement position is restricted. In a state in which a plurality of panels are accommodated in the container body 2, the front end of each panel is located behind the sealing surface of the flange 25 (the surface with which the sealing surface 33a abuts).

Next, a method for manufacturing the lid 3 (panel storage container 1) will be described. First, a plate-like back surface material that forms the back surface 31b of the lid body 31 is prepared. A cutting tool (cutter) for dovetail groove processing is pierced into a position near the periphery of the backing material, the cutting tool is moved along the periphery of the backing material, and the cutting tool is removed from the position. Thereby, the mounting portion 35 is formed. Since the pair of locking pieces 35b are not formed at the position where the cutting tool is stuck, this portion corresponds to the missing portion 35c.

Similarly, the cutting tool is pierced into the position where the lower end of the restricting portion 41 is provided, and after the cutting tool is moved to the position where the upper end of the restricting portion 41 is provided, the cutting tool is moved to the above position, and the cutting tool is moved from the above position. Tool is removed. Thereby, a mounting portion 36 for mounting the restricting portion 41 is formed. Since the pair of locking pieces 36b are not formed at the position where the cutting tool is stuck, this portion corresponds to the missing portion 36c. A mounting portion 36 for mounting the restricting portions 42 and 43 is also formed in the same manner.

Subsequently, an elongated elastic member having a uniform cross-sectional shape is prepared as the base of the sealing member 33 and the retainer 34 . Then, the sealing member 33 is prepared by cutting the elastic member to the length of the sealing member 33 and connecting the ends thereof. The sealing member 33 manufactured in this manner has an annular shape with no directivity. Similarly, the restricting portions 41 to 43 are prepared by cutting the elastic members to the lengths of the restricting portions 41 to 43, respectively.

Subsequently, the sealing member 33 is pushed into the groove portion 35a from between the pair of locking pieces 35b and held in the groove portion 35a by the pair of locking pieces 35b. Similarly, the restricting portions 41 to 43 are pushed into the groove portion 36a from between the pair of locking pieces 36b and held in the groove portion 36a by the pair of locking pieces 36b.

Subsequently, a plate-like surface material that forms the front surface 31a and the locking mechanism 32 are prepared, and the surface material, the locking mechanism 32, and the back surface material are combined. As described above, the lid body 3 is manufactured.

In the panel storage container 1 described above, the lid body 31 is provided with the sealing member 33 and the retainer 34 . The cross-sectional shape of the retainer 34 is the same as the cross-sectional shape of the sealing member 33 , and the constituent material of the retainer 34 is the same as the constituent material of the sealing member 33 . Therefore, since one type of elastic member can be used as the sealing member 33 and the retainer 34, there is no need to prepare an elastic member for the sealing member 33 and an elastic member for the retainer 34, respectively. Since the elastic member can be shared by the sealing member 33 and the retainer 34 in this manner, the manufacture of the panel container 1 can be simplified. Furthermore, it becomes possible to reduce costs.

In a state in which the lid 3 closes the opening 2a, the restricting portions 41 and 42 face the vicinity of both ends of each panel in the front-rear direction. Therefore, since each panel is restricted from moving in the front-rear direction at two positions in the left-right direction (both ends of each panel), movement in the front-rear direction of each panel can be more reliably restricted.

In a state in which the lid body 3 closes the opening 2a, in addition to the restricting portions 41 and 42, the restricting portion 43 faces each panel in the front-rear direction. Therefore, each panel is restricted from moving in the front-rear direction at three positions in the left-right direction, so that the movement of each panel in the front-rear direction can be more reliably restricted.

The lid body 31 includes an attachment portion 35 for attaching the sealing member 33 and an attachment portion 36 for attaching the retainer 34 . Therefore, the sealing member 33 and the retainer 34 can be attached to the lid body 31 by the attaching portion 35 and the attaching portion 36 .

Specifically, since the attachment portion 35 has a dovetail groove structure, the sealing member 33 is attached to the lid body 31 simply by fitting the sealing member 33 into the attachment portion 35 . Therefore, it is possible to simplify the mounting of the sealing member 33 . Since there is no need to provide a complicated structure for holding the sealing member 33, the thickness of the lid 3 can be reduced and the structure of the lid 3 can be simplified.

Similarly, since the attachment portion 36 has a dovetail groove structure, the retainer 34 can be attached to the lid body 31 simply by fitting the retainer 34 into the attachment portion 36 . Therefore, attachment of the retainer 34 can be simplified. Since there is no need to provide a complicated structure for holding the retainer 34, the thickness of the lid 3 can be reduced and the structure of the lid 3 can be simplified.

In a state in which a plurality of panels are accommodated in the container body 2, the front ends of the panels are positioned behind the sealing surface of the flange 25. - 特許庁Therefore, the retainer 34 contacts the front end of the panel with a force smaller than the force with which the sealing member 33 is pressed against the sealing surface of the flange 25 . Therefore, even if one type of elastic member is used as the sealing member 33 and the retainer 34, it is possible to improve the airtightness of the panel storage container 1 while reducing the possibility of damage to the panel.

Note that the panel storage container according to the present disclosure is not limited to the above embodiments.

In the above embodiment, screws are used as an example of the fixing member, but another fixing member may be used instead of the screws.

The method of connecting each member of the container body 2 may be different from the above embodiment. In the above embodiment, the container body 2 is configured by combining a plurality of parts, but it may be an integrally molded product.

The cross-sectional shapes of the sealing member 33 and the retainer 34 are not limited to the cross-sectional shapes of the above embodiments. The cross-sectional shape of the sealing member 33 may be any shape as long as it can exhibit the function of the sealing member 33 . The cross-sectional shape of the retainer 34 may be any shape as long as it can exhibit the function of the retainer 34 .

For example, as shown in (a) of FIG. 6, the cross-sectional shapes of the sealing member 33 and the retainer 34 may be circular. That is, a round string-like elastic member may be used as the sealing member 33 and the retainer 34 . As shown in FIG. 6B, the cross-sectional shapes of the sealing member 33 and the retainer 34 may be triangular. As shown in (c) of FIG. 6, the cross-sectional shapes of the sealing member 33 and the retainer 34 may be plus shapes. As shown in (d) of FIG. 6, the cross-sectional shapes of the sealing member 33 and the retainer 34 may be inverted T-shaped. As shown in (e) of FIG. 6, the cross-sectional shapes of the sealing member 33 and the retainer 34 may be X-shaped. As shown in (f) of FIG. 6, the cross-sectional shapes of the sealing member 33 and the retainer 34 may be inverted Y-shaped.

The retainer 34 may include at least one of the restricting portions 41-43. For example, the retainer 34 may not include the restricting portion 43 . The restricting portion 41 and the restricting portion 42 need only be provided apart from each other in the left-right direction of the lid body 31 (back surface 31b), and need not be provided at the pair of end portions 31c. In this case as well, when the lid 3 closes the opening 2a, the restricting portions 41 and 42 face each panel in the front-rear direction. Therefore, since each panel is restricted from moving in the front-rear direction at two locations in the left-right direction, it is possible to more reliably restrict the movement of each panel in the front-rear direction.

The lid 3 is not limited to the configuration of the above embodiment. FIG. 7 is a rear view showing a modification of the lid. As shown in FIG. 7, the lid body 3A mainly differs from the lid body 3 in that the lid body 31 and the retainer 34 are replaced with a lid body 31A and a retainer 34A.

The retainer 34</b>A is mainly different from the retainer 34 in that the retainer 34</b>A includes a connecting portion 44 (first connecting portion) instead of the restricting portion 43 . The connecting portion 44 is a portion that connects the upper end (one end) of the restricting portion 41 and the upper end (one end) of the restricting portion 42 . That is, the retainer 34A is one member that continues in the order of the restricting portion 41, the connecting portion 44, and the restricting portion 42, and has an inverted U shape. The connecting portion 44 has a curved portion 44a and a curved portion 44b. The curved portion 44 a is a portion connected to the upper end of the restricting portion 41 . The curved portion 44 b is a portion connected to the upper end of the restricting portion 42 .

The lid body 31A differs from the lid body 31 mainly in the position where the mounting portion 36 is provided. Since the retainer 34A is one elastic member having an inverted U-shape, the mounting portion 36 includes one groove portion 36a corresponding to the retainer 34A. Accordingly, the mounting portion 36 includes one missing portion 36c.

Also in the panel storage container provided with the lid 3A, the same effects as those of the panel storage container 1 according to the above-described embodiment can be obtained with respect to the configuration common to the panel storage container 1 according to the above-described embodiment. Furthermore, the following effects are also exhibited in the panel storage container provided with the cover 3A.

For example, the retainer is attached to the lid body with one end of the retainer as a reference. For this reason, if the length of the retainer is not as designed, excess or deficiency may occur at the other end of the retainer. When the retainer 34 includes a plurality of physically separated portions (restricting portions 41 to 43) as in the above embodiment, excess or deficiency may occur at the ends of each portion. On the other hand, in the lid body 3A, the retainer 34A is one member that continues in the order of the restricting portion 41, the connecting portion 44, and the restricting portion 42. Therefore, the retainer (retainer) is composed of a plurality of physically separated members. 34), the number of edges can be reduced. Therefore, it is possible to reduce the possibility that the retainer 34A is excessive or insufficient. Note that the connecting portion 44 may connect the lower end of the restricting portion 41 and the lower end of the restricting portion 42 . The retainer 34A may further include a restriction portion 43. As shown in FIG.

FIG. 8 is a rear view showing another modification of the lid. As shown in FIG. 8, the lid 3B mainly differs from the lid 3A in that it includes a lid body 31B and a retainer 34B instead of the lid body 31A and the retainer 34A.

The retainer 34B mainly differs from the retainer 34A in that it further includes a connecting portion 45 (second connecting portion). The connecting portion 45 is a portion that connects the lower end (the other end) of the restricting portion 41 and the lower end (the other end) of the restricting portion 42 . That is, the retainer 34B has a rectangular annular shape in which the restricting portion 41, the connecting portion 44, the restricting portion 42, and the connecting portion 45 circulate in this order. The connecting portion 45 has a curved portion 45a and a curved portion 45b. The curved portion 45 a is a portion connected to the lower end of the restricting portion 41 . The curved portion 45 b is a portion connected to the lower end of the restricting portion 42 .

The lid main body 31B differs from the lid main body 31A mainly in the position where the mounting portion 36 is provided. Since the retainer 34B is an elastic member having a rectangular annular shape, the mounting portion 36 includes one rectangular annular groove portion 36a corresponding to the retainer 34B. Accordingly, the mounting portion 36 includes one missing portion 36c.

Also in the panel storage container provided with the lid body 3B, the same effect as the panel storage container 1 according to the above embodiment can be obtained with respect to the configuration common to the panel storage container 1 according to the above embodiment. Furthermore, in the panel storage container including the lid 3B, the retainer 34B has an annular shape in which the restricting portion 41, the connecting portion 44, the restricting portion 42, and the connecting portion 45 circulate in this order. Therefore, since the retainer 34B has an endless shape, excess or deficiency of the retainer 34B at the ends can be eliminated. Note that the retainer 34B may further include a restricting portion 43 .

In the panel storage container 1 , the cross-sectional shape of the retainer 34 is the same as that of the sealing member 33 , and the constituent material of the retainer 34 is the same as that of the sealing member 33 . The relationship with the retainer 34 is not limited to this relationship. The cross-sectional shape of the retainer 34 may be the same as the cross-sectional shape of the sealing member 33 , and the constituent material of the retainer 34 may be different from the constituent material of the sealing member 33 . Similarly, in the panel container provided with the lid 3A, the cross-sectional shape of the retainer 34A may be the same as the cross-sectional shape of the sealing member 33, and the constituent material of the retainer 34A may differ from the constituent material of the sealing member 33. good. Similarly, in the panel storage container provided with the lid 3B, the cross-sectional shape of the retainer 34B may be the same as the cross-sectional shape of the sealing member 33, and the constituent material of the retainer 34B may differ from the constituent material of the sealing member 33. good.

In these cases, the retainers 34 , 34 A, 34 B have the same cross-sectional shape as the sealing member 33 . Therefore, a common mold can be used as a mold for manufacturing the sealing member 33 and the retainers 34, 34A, 34B. There is no need to prepare a mold for each. In this way, the sealing member 33 and the retainers 34, 34A, 34B can share a mold, so that the cost can be reduced and the manufacturing of the panel storage container can be simplified.

In the panel storage container 1 , the cross-sectional shape of the retainer 34 may be different from that of the sealing member 33 , and the constituent material of the retainer 34 may be the same as that of the sealing member 33 . Similarly, in the panel container provided with the lid 3A, the cross-sectional shape of the retainer 34A is different from the cross-sectional shape of the sealing member 33, and the constituent material of the retainer 34A is the same as the constituent material of the sealing member 33. may Similarly, in the panel container provided with the lid 3B, the cross-sectional shape of the retainer 34B is different from the cross-sectional shape of the sealing member 33, and the constituent material of the retainer 34B is the same as the constituent material of the sealing member 33. may A modification in which the cross-sectional shape of the sealing member and the cross-sectional shape of the retainer are different and the material of the sealing member and the material of the retainer are the same will be described with reference to FIG. 9 .

FIG. 9 is a rear view showing still another modification of the lid. As shown in FIG. 9, the lid body 3C is mainly different from the lid body 3 in that the lid body 31 and the retainer 34 are replaced with a lid body 31C and a retainer 34C. The retainer 34C is a plate-like elastic member extending with a uniform cross-sectional shape. The retainer 34C is mainly different from the retainer 34 in that it includes a restricting portion 41C and a restricting portion 42C instead of the restricting portions 41-43. The restricting portion 41C differs from the restricting portion 41 mainly in the shape and the mounting method to the lid body 31C. Similarly, the restricting portion 42C mainly differs from the restricting portion 42 in the shape and the mounting method to the lid body 31C. The restricting portions 41C and 42C have a plate-like shape and are attached to the back surface 31b with an adhesive or the like.

The lid body 31C does not have a dovetail groove structure for attaching the retainer 34C to the lid body 31C. In this modified example, the adhesive material that affixes the restricting portions 41C and 42C to the rear surface 31b functions as a mounting portion. As with the retainer 34C, the sealing member 33 may also be attached to the rear surface 31b with an adhesive or the like. Note that the retainers 34, 34A, and 34B may also be attached to the back surface 31b with an adhesive or the like.

Also in the panel storage container provided with the lid 3C, the same effects as those of the panel storage container 1 according to the above-described embodiment can be obtained with respect to the configuration common to the panel storage container 1 according to the above-described embodiment. In the panel storage container provided with the lid 3C, the retainer 34C is made of the same material as the sealing member 33. As shown in FIG. Therefore, since the sealing member 33 and the retainer 34C can be manufactured using one type of material, there is no need to prepare a material for the sealing member 33 and a material for the retainer 34C. . In this way, the sealing member 33 and the retainer 34C can share the same constituent material, so that the cost can be reduced and the manufacturing of the panel storage container can be simplified. Furthermore, in the panel storage container provided with the lid 3C, there is no need to form the dovetail groove structure in the lid main body 31C, so it is possible to simplify the manufacture of the panel storage container (the lid 3C).

(a) of FIG. 10 is a diagram showing still another modification of the lid. FIG. 10(b) is a cross-sectional view taken along line Xb--Xb of FIG. 10(a). (a) of FIG. 11 is a diagram showing a state in which the lid body shown in (a) of FIG. 10 closes the opening. FIG. 11(b) is a cross-sectional view taken along line XIb--XIb of FIG. 11(a). As shown in FIG. 10(a), the lid 3D is mainly similar to the lid 3 in that it further includes a cushioning material 37 (first cushioning material) and a cushioning material 38 (second cushioning material). differ.

The cushioning material 37 is an elastic member having hardness lower than that of the sealing member 33 . In this example, the durometer hardness (Shore A) of the sealing member 33 is about 50 to 70 degrees, and the durometer hardness (Shore A) of the cushioning material 37 is about 20 to 30 degrees. The cushioning material 37 is, for example, sponge rubber. The cushioning material 37 is provided between the sealing member 33 and the lid body 31 . In the example shown in (a) of FIG. 10 , the cushioning material 37 is provided along the groove 35 a and positioned between the bottom wall of the groove 35 a and the sealing member 33 . The cushioning material 37 is provided over the entire sealing member 33 .

The cushioning material 38 is an elastic member having hardness lower than that of the retainer 34 . In this example, the durometer hardness (Shore A) of the retainer 34 is about 50 to 70 degrees, and the durometer hardness (Shore A) of the cushioning material 38 is about 20 to 30 degrees. The cushioning material 37 is, for example, sponge rubber. A cushioning material 38 is provided between the retainer 34 and the lid body 31 . In the example shown in FIG. 10( a ), the cushioning material 38 is provided along the groove 36 a and positioned between the bottom wall of the groove 36 a and the retainer 34 . A cushioning material 38 is provided over the entire retainer 34 .

Also in the panel storage container provided with the lid body 3D, the same effects as those of the panel storage container 1 according to the above-described embodiment can be obtained with respect to the configuration common to the panel storage container 1 according to the above-described embodiment. Furthermore, the panel storage container provided with the lid body 3D also has the following effects.

For example, in the panel storage container 1, if only the sealing member 33 having a low hardness is laid in the groove portion 35a, the sealing member 33 is easily deformed. Unevenness may occur on the sealing surface 33a. As a result, even when the lid 3 is locked, a gap is generated between the sealing member 33 and the container body 2 (flange 25), and the airtightness of the panel storage container 1 (accommodation space 20) may be impaired. There is When only the sealing member 33 having high hardness is laid in the groove portion 35a, the sealing surface 33a of the sealing member 33 is flat, but the sealing member 33 is hard to be crushed. The latch torque of mechanism 32 is increased. As a result, the locking of the lid body 3 becomes insufficient, and there is a risk that the airtightness of the panel storage container 1 (accommodation space 20) will be impaired.

On the other hand, in the lid 3D, a cushioning material 37 is laid in the groove 35a, and the sealing member 33 is laid on the cushioning material 37. As shown in FIG. In this case, even if the surface of the cushioning material 37 on which the sealing member 33 is provided becomes uneven, the sealing member 33 provided thereon is less likely to deform, so the sealing surface 33a of the sealing member 33 is flattened. be able to. When the lid 3 is locked, the cushioning material 37 is crushed, so that an increase in the latch torque of the locking mechanism 32 can be suppressed. Therefore, it is possible to reduce the possibility of creating a gap between the sealing member 33 and the container body 2 (flange 25), and to lock the lid 3 more reliably. As a result, it is possible to improve the airtightness of the panel container.

Similarly, when only the retainer 34 having a low hardness is installed in the groove portion 36a, the contact surface 34a of the retainer 34 may become uneven. As a result, when the lid 3 closes the opening 2a, a gap is created between the contact surface 34a of the retainer 34 and the front end of the panel, and there is a possibility that the movement of the panel in the front-rear direction cannot be sufficiently restricted. . When only the retainer 34 having high hardness is laid in the groove 36a, the contact surface 34a of the retainer 34 is flat, but the retainer 34 is hard to be crushed, so excessive force is applied to the front end of the panel and the panel is damaged. There is a risk.

On the other hand, in the lid 3D, a cushioning material 38 is laid in the groove 36a, and the retainer 34 is laid on the cushioning material 38. As shown in FIG. In this case, even if the surface of the cushioning material 38 on which the retainer 34 is provided becomes uneven, the retainer 34 provided thereon is less likely to deform, so the contact surface 34a of the retainer 34 can be flattened. When the cover 3 is locked and the front end of the panel abuts against the retainer 34, the cushioning material 38 is crushed to prevent excessive force from being applied to the front end of the panel. Therefore, it is possible to more reliably restrict the movement of each panel in the front-rear direction, and reduce the possibility of damage to the panel.

In the panel storage container including the lid body 3D, the cross-sectional shape of the sealing member 33 and the cross-sectional shape of the retainer 34 are the same, and the material constituting the sealing member 33 and the material constituting the retainer 34 are different. Alternatively, the cross-sectional shape of the sealing member 33 and the cross-sectional shape of the retainer 34 may be different, and the constituent material of the sealing member 33 and the constituent material of the retainer 34 may be the same.
