JP-A-8-198370

  In the conventional transport container described above, since the cylindrical core member is merely inserted into the rib protruding from the bottom, the core member is removed from the bottom when the article is removed from the core member. There is a problem that the ribs projecting from the ribs are removed, the remaining articles collapse, and the articles are damaged.

  In the case of a transport container in which the core member is detachably attached, when returning an empty transport container to the manufacturing site of the article, the core member is removed from the main body of the transport container and transported. The main body of the container and the core member are managed separately, and there is a problem that the core member is lost.

  An object of the present invention is to solve the problems of the above-described conventional transport container.

  In order to achieve the above-described object, the present invention provides a transport container including a container body and a core member that is detachably attached to a bottom portion of the container body. First, the core member includes the container body. The core member is prevented from being pulled upward by rotating the core member from a pullable state that can be pulled upward while being fitted to a fitting member erected on the bottom of the core. Secondly, a fitting member is erected on the bottom of the container body, and a pair of latches are provided on the outer peripheral side surface of the fitting member. A locking cylinder body having a protrusion protruding thereon is provided, and the locking cylinder insertion hole into which the locking cylinder body can be inserted and the locking protrusion in the vicinity of the end of the core member Forming a locking annular body in which a recess is formed, The fitting member is fitted into the fitting space of the core member, and the locking cylinder is inserted into the locking cylinder insertion hole of the locking annular body. After inserting the locking projection protruding from the locking cylinder into the recess formed in the locking annular body, the core member is rotated to protrude into the locking cylinder. The locking protrusion provided and the recess formed in the locking annular body are configured so as not to overlap, and thirdly, the locking annular body is disposed in one direction of the core member. An anti-rotation rib in the opposite direction that allows only the rotation of the core member and prevents the core member from rotating in the opposite direction, and an inclined surface and a horizontal plane on which the locking protrusion protruding from the locking cylinder can ride. A thick portion having an over-rotation prevention rib for preventing over-rotation of the core member, and fourth, an outer periphery of the fitting member An annular recess is formed on the upper surface of the bottom so as to surround the surface. Fifth, a fitting member comprising a cylindrical support and a top plate is erected on the bottom of the container body. In addition, a locking female member having a locking male projection insertion opening formed on one side is formed, and a locking male projection to be inserted into the locking female member is formed on the end surface of the core member. Sixth, the container body is a container body that can be nested and stacked.

  The core member is fitted to a fitting member standing on the bottom of the container body, and the core member is pulled upward by rotating the core member from a pullable state where the core member can be pulled upward. Since the core member is pulled out from the bottom when the article is extracted from the core member, the remaining article collapses and the article is damaged. Can be surely prevented.

  A fitting member is erected at the bottom of the container body, and a locking cylinder having a pair of locking projections projecting from an outer peripheral side surface is erected on the top of the fitting member, A locking annular body is formed in the vicinity of the end of the core member, in which a locking cylinder insertion hole into which the locking cylinder can be inserted and a recess into which the locking projection can be inserted are formed. The fitting member is fitted into the fitting space of the core member, and the locking cylinder is inserted into the locking cylinder insertion hole of the locking annular body, and Then, after inserting the locking projection protruding from the locking cylinder into the recess formed in the locking annular body, the core member is rotated to thereby rotate the locking cylinder. Since the projecting locking projection and the recess formed in the locking annular body do not overlap, the core member is fitted with the core member standing on the bottom. Even if a load such as pulling out from the material is applied, the locking protrusion protruding from the locking cylinder comes into contact with the locking annular body formed on the core member. It can be surely prevented from being pulled out of the fitting member.

  An anti-rotation rib for the opposite direction that allows the locking annular body to rotate in only one direction of the core member and prevents the rotation of the core member in the opposite direction, and a locking protrusion protruding from the locking cylinder. Since a thick part having an inclined surface and a horizontal surface that can be ridden and an over-rotation prevention rib that prevents over-rotation of the core member are formed, the opposite direction anti-rotation rib causes the opposite direction to the thick part of the cylindrical member Can be prevented, and the thick part can press the end face of the core member against the upper surface of the bottom part to prevent the movement of the cylindrical member. Over-rotation can be prevented, and the locking projections protruding from the locking cylinder can be prevented from coming off the thick portion.

  Since the annular recess is formed on the upper surface of the bottom so as to surround the outer peripheral side surface of the fitting member, the burrs formed on the end surface of the semi-cylindrical core are the upper surface of the annular recess and the article positioned at the bottom. Therefore, the burr does not come into contact with the lower surface or the central hole located near the core member of the article located at the bottom, and therefore, the half cylinder The burrs formed on the end face of the core can prevent the article located at the bottom from being damaged.

  A fitting member comprising a cylindrical support and a top plate is erected at the bottom of the container body, and a locking female member having a locking male projection insertion opening formed on one side is formed. Since the locking male projection to be inserted into the locking female member is formed on the end surface of the core member, a load that pulls the core member from the fitting member standing on the bottom is applied to the core member. In addition, since the locking male protrusion formed on the core member comes into contact with the locking female member, the core member can be reliably prevented from being pulled out of the fitting member.

  Since the container body is a container body capable of nesting and stacking, the core member removed from the empty container body is positioned between the bottom of the container body positioned above and the bottom of the container body positioned below in the nesting state. Since the container main body is nested, the storage space for the empty transport container can be reduced, and accordingly, the empty transport container can be stored. Storage efficiency can be improved.

This is a through-hole for the mold to be pulled out.

  Next, the core member C1 that is supported by the fitting member 4 that is erected on the bottom 1 described above will be described with reference to FIGS. The transport container B is composed of the container body B 'and the core member C1 described above.

  The core member C1 is formed by joining a pair of semi-cylindrical core bodies C1 'having the same configuration in the shape of a half of a cylinder.

  The semi-cylindrical core body C1 ′ includes a semi-cylindrical body c1 ′ having a half-cylinder shape, and a flat plate-shaped semicircular body c2 ′ for partition walls formed on the inner wall surface near the center of the semi-cylindrical body c1 ′. And a semicircular body c3 ′ for locking formed on the inner wall surface near both ends of the semicylindrical body c1 ′. In this embodiment, an example in which two partition semicircles c2 'are formed is shown.

  The locking semi-annular body c3 ′ is formed by cutting out the central portion of the linear end edge of the flat semicircular plate into a semicircular shape. Is formed with a flat semicircular portion c3a ′ and a half hole c4a ′. Further, the locking semi-annular body c3 ′ is formed with a rectangular recess c4b by notching the central portion of the semi-peripheral edge c4a ″ of the half hole c4a ′, and the recess c4b has an opposing edge c4b. 'And the back edge c4b ".

  The surface of the semi-annular portion c3a ′ constituting the locking semi-annular portion c3 ′ located on the opposite side to the partition semicircle c2 ′ is formed as a flat surface, and the semi-annular portion c3a ′ has a partition wall. As shown in FIG. 9 and the like, a thick body c7 having an anti-rotation rib c5, an anti-rotation rib c6 in the opposite direction, and an inclined surface c7 ′ is formed on the surface facing the semicircular body c2 ′. Has been.

  The over-rotation preventing rib c5 is one corner portion of opposing corner portions formed by the substantially linear end edge c3a ″ of the semi-annular portion c3a ′ and the semicircular peripheral edge c4a ″ forming the half hole c4a ′. It is formed as an elongated plate-like body extending from c8a ′ to the inner wall surface of the semi-cylindrical body c1 ′ substantially perpendicularly to the substantially linear edge c3a ″ of the semi-annular part c3a ′.

  The counter-rotation preventing rib c6 in the opposite direction is along the facing edge c4b ′ located on the over-rotation preventing rib c5 side of the facing edges c4b ′ of the rectangular recess c4b formed in the locking semi-annular body c3 ′. In addition, it is formed so as to be substantially parallel to the over-rotation preventing rib c5. The opposite direction rotation prevention rib c6 is formed as an elongated plate-like body extending from the semicircular peripheral edge c4a ″ forming the half hole c4a ′ of the semiannular part c3a ′ to the inner wall surface of the semicylindrical body c1 ′. Yes.

  The inclined surface c7 ′ is the other corner portion of the opposite corner portions formed by the substantially linear end edge c3a ″ of the semi-annular portion c3a ′ and the semicircular peripheral edge c4a ″ forming the half hole c4a ′. From c8a ′, from the semicircular peripheral edge c4a ″ that is substantially parallel to the over-rotation prevention rib c5 and the counter-rotation prevention rib c6 and that forms the half hole c4a ′ of the semi-annular portion c3a ′, It is formed as a part of a strip-shaped thick body c7 extending to the wall surface, and the thick body c7 is inclined in an uphill shape from the inner wall surface of the semi-cylindrical body c1 ′ located on the opposite direction rotation prevention rib c6 side. And an inclined plane c7 ′ and a horizontal plane c7 ″ substantially parallel to the semi-annular portion c3a ′.

  c9 ′ is obtained by deleting the outer peripheral surface of the semi-cylindrical body c1 ′ near the edge extending in the direction toward the center line L1 (see FIG. 5) of the semi-cylindrical body c1 ′ by a predetermined depth, It is a step part formed by forming thin wall c10 '. An appropriate number of slots c11 are formed in one thin wall portion c10 ′ of the opposed thin wall wall c10 ′, and a horizontally long shape formed by extending a predetermined portion of the thin wall portion c10 ′ upward. A fitting protrusion c13 that is perpendicular to the belt-like extension plate portion c12 and extends outward is formed at the upper end edge of the belt-like extension plate portion c12. In addition, an appropriate number of slots c11 and fitting protrusions c13 are also formed in the other thin wall portion c10 ′ of the opposed thin wall c10 ′, with the center line L1 of the semi-cylindrical body c1 ′ sandwiched therebetween, The other thin-walled portion c10 ′ in line symmetry with the slot c11 formed in one thin-walled portion c10 ′ is formed with a fitting protrusion c13 via a belt-like extension plate portion c12, and half The other thin-walled portion c10 ′ in line symmetry with the fitting protrusion c13 formed on one thin-walled portion c10 ′ via the belt-like extension plate portion c12 across the center line L1 of the cylindrical body c1 ′. Is formed with a slot c11.

  In the slot c11 formed in one semicylindrical core C1 ′ of the pair of semicylindrical cores C1 ′ described above, the fitting protrusion c13 formed in the other semicylindrical core C1 ′. And the fitting protrusion c13 formed in one semi-cylindrical core C1 ′ is fitted into the slot c11 formed in the other semi-cylindrical core C1 ′. Thus, the pair of semi-cylindrical cores C1 ′ is assembled into the substantially cylindrical core member C1 as shown in FIG.

  By assembling the pair of semicylindrical cores C1 ′, a partition wall c2 including a pair of partition semicircles c2 ′ is formed on the inner wall surface near the center of the core member C1. On the inner wall surface in the vicinity of both ends, a locking annular body c3 comprising a pair of locking semi-annular bodies c3 ′ is formed. Further, the locking annular body c3 has a locking hole comprising a half hole c4a ′. The cylinder insertion hole c4a is formed. Further, on the outer peripheral surface of the core member C1, a groove part c9 formed by a step part c9 'forming a thin wall c10' is formed along the center line of the core member C1. A flat annular portion c3a is formed in the locking annular body c3 by the flat semicircular portion c3a 'of the pair of locking semi-annular bodies c3'.

  The locking semi-annular body c3 'can be formed only in the vicinity of one end of the pair of semi-cylindrical core bodies C1'. In this case, the locking annular body c3 is formed only in the vicinity of one end of the core member C1. Thus, when the locking annular body c3 is formed only in the vicinity of one end of the core member C1, the fitting member 4 standing on the bottom 1 of the container body B ′ When the core member C1 is fitted, the end of the core member C1 on which the locking annular body c3 is formed must be confirmed by the operator one by one. The workability of the fitting operation of the member C1 is deteriorated. Therefore, it is preferable to form the locking annular bodies c3 in the vicinity of both ends of the core member C1. When the locking annular body c3 is formed only near one end of the core member C1, the end of the core member C1 where the locking annular body c3 is formed is colored. By attaching the identification label or the like, the workability of the fitting work of the core member C1 to the fitting member 4 can be improved.

  As described above, the fitting protrusion c13 formed in the other semi-cylindrical core C1 ′ is fitted into the slot c11 formed in one semi-cylindrical core C1 ′, and A pair of semi-cylindrical shapes are formed by fitting the fitting protrusion c13 formed in one semi-cylindrical core body C1 ′ into the slot c11 formed in the other semi-cylindrical core body C1 ′. The core body C1 ′ is assembled to the substantially cylindrical core member C1, and the coupling portion between the slot c11 and the fitting protrusion c13 is formed on the outer peripheral surface of the core member C1 along the center line of the core member C1. It is located in the groove c9 that is formed, and is configured not to protrude from the outer peripheral surface of the core member C1. Therefore, the center hole w1 drilled in the article W inserted in the core member C1 is caught in the fitting portion between the slot c11 and the fitting protrusion c13, and the article W can be inserted into the core member C1. It is possible to prevent the article W from being damaged or damaged.

  On the surface facing the partition wall c2 of the locking annular body c3, that is, on the inner surface of the locking annular body c3, as shown in FIG. 10 and FIG. On the other hand, a pair of over-rotation prevention ribs c5 are respectively disposed at the point target positions, and similarly, a pair of opposite directions are provided at the point target positions with respect to the center point of the locking annular body c3. Anti-rotation ribs c6 are respectively disposed, and similarly, a pair of thick portions c7 are disposed at point target positions with respect to the center point of the locking annular body c3. Further, the height D1 (see FIG. 7) from the end surface c14 of the core member C1 to the outer surface of the locking annular body c3 is the height of the fitting member 4 erected on the bottom 1 of the container body B ′. Height (distance from the upper surface 1b1 of the annular recess 1b to the upper surface of the top plate 4b of the cylindrical support 4a constituting the fitting member 4) D2 (see FIG. 3) is slightly higher. It is configured.

  Next, the attachment of the core member C1 to the bottom 1 of the container main body B 'described above will be mainly described with reference to FIGS.

  A cylindrical support 4a constituting the fitting member 4 standing on the bottom 1 is fitted into the fitting space A1 of the core member C1 formed between the end face c14 and the locking annular body c3. At the same time, the locking cylinder 5 standing on the top plate 4b of the cylindrical support 4a is inserted into the locking cylinder insertion hole c4a of the locking annular body c3 and is used for locking. The pair of locking projections 5c protruding from the cylindrical body 5 are inserted into the pair of recesses c4b formed in the locking annular body c3. As shown in FIG. 10, the fitting member 4 is fitted into the fitting space A1 of the core member C1, and the locking cylinder 5 is used for locking the locking annular body c3. In a state where the locking projection 5c inserted into the cylindrical insertion hole c4a and further protruding from the locking cylinder 5 is inserted into the recess c4b formed in the locking annular body c3, The end surface c14 of the core member C1 is in contact with the upper surface 1b1 of the annular recess 1b formed in the bottom 1, and the locking projection 5c protruding from the locking cylinder 5 is the locking annular body c3. It is configured to be located slightly above the flat plate-like annular portion c3a. Furthermore, in this state, as shown in FIG. 10, the pair of locking projections 5c approach the side surface c6a on the inclined surface c7 ′ side of the thick portion c7 of the opposite direction rotation prevention rib c6, respectively. Is located.

  As shown in FIG. 10, the fitting member 4 erected on the bottom 1 is fitted into the fitting space A1 of the core member C1, and the locking cylinder 5 is used for locking. A locking projection 5c inserted into the locking cylinder insertion hole c4a of the annular body c3 and projecting from the locking cylinder 5 is formed in a recess c4b formed in the locking annular body c3. In the inserted state, the core member C1 is pulled out of the fitting member 4 by lifting the core member C1 upward. This state is referred to as a state in which the core member C1 can be pulled out.

  When the core member C1 is rotated in the counterclockwise direction R1 in FIG. 10 from the state described above, the pair of locking protrusions 5c protruding from the locking cylinder 5 constitutes the core member C1. The thick portion c7 of the opposite direction rotation prevention rib c6 formed on the locking annular body c3 comes into contact with the side surface c6a on the inclined surface c7 ′ side, and its rotation is prevented, and therefore the core member C1. Is still in a state where it can be pulled out (a state in which the core member C1 can be pulled out), and the attachment to the locking cylinder 5 standing on the fitting member 4 is not completed. On the other hand, in the case where the core member C1 is rotated in the clockwise direction R2 in FIG. 10, the locking protrusion 5c does not come into contact with the counterclockwise rotation prevention rib c6. Rotation is allowed.

  When the core member C1 is rotated in the clockwise direction R2 in FIG. 10, the locking protrusion 5c protruding from the locking cylinder 5 is formed on the locking annular body c3 constituting the core member C1. Ride on the inclined surface c7 ′ of the thick part c7, and then, as shown in FIG. 11, it is placed on the horizontal plane c7 ″ of the thick part c7. The locking projection 5c protruding from the locking cylinder 5 rides on the inclined surface c7 ′ of the thick part c7, and is pushed down in the direction of the upper surface 1b1 of the annular recess 1b formed in the bottom 1, The end surface c14 of the member C1 is brought into pressure contact with the upper surface 1b1 of the annular recess 1b. Therefore, the core member C1 is erected on the bottom portion 1 so as not to move with respect to the bottom portion 1. It will be attached to the fitting member 4 and the locking cylinder 5.

  Finally, as described above, the locking protrusion 5c is placed on the horizontal surface c7 ″ of the thick portion c7 formed on the locking annular body c3 constituting the core member C1. Therefore, the possibility that the core member C1 rotates counterclockwise is always less than that in the case where the locking protrusion 5c is located on the inclined surface c7 ′, and the core member C1 is in a stable state. However, it will be attached to the fitting member 4 and the locking cylinder 5 erected on the bottom 1.

  Further, when the locking projection 5c is placed on the horizontal surface c7 "of the thick portion c7 formed on the locking annular body c3 constituting the core member C1, the locking projection 5c protrudes from the locking cylinder 5. The over-rotation preventing rib c5 formed on the locking annular body c3 constituting the core member C1 is in contact with the provided locking projection 5c, and further rotation of the core member C1 is prevented. Accordingly, the locking projection 5c protruding from the locking cylinder 5 is a horizontal surface of the thick portion c7 formed on the locking annular body c3 constituting the core member C1. It is possible to prevent movement beyond c7 ″ and disengagement from the horizontal surface c7 ″ of the thick part c7. The locking projection 5c protruding from the locking cylinder 5 constitutes the core member C1. When it comes off from the horizontal surface c7 ″ of the thick part c7 formed in the locking annular body c3, the core member C1 The pressure contact with the upper surface 1b1 of the annular recess 1b of the end surface c14 is released, and the core member C1 becomes easy to move with respect to the bottom 1, and articles inserted into the core member C1 rub against each other. Will be damaged.

  Furthermore, as described above, the locking annular body c3 constituting the core member C1 is provided with the anti-rotation rib c6 in the opposite direction, the thick portion c7, and the over-rotation prevention rib c5 in this order in the core member C1. Therefore, when the counterclockwise rotation prevention rib c6 is formed, as described above, the rotation of the core member C1 in the counterclockwise direction R1 is prevented. Thus, the core member C1 rotates only in the clockwise direction R2. Therefore, the locking protrusion 5c protruding from the locking cylinder 5 is placed on the horizontal surface c7 ″ of the thick part c7 and is excessive. However, if the opposite direction anti-rotation rib c6 is not formed, the core member C1 is mistakenly moved in the counterclockwise direction R1. Therefore, it will protrude into the locking cylinder 5. Before the latching protrusion 5c is moved over the thick portion c7, it comes into contact with the over-rotation preventing rib c5 and its rotation is prevented, and the latching protrusion 5c protruding from the latching cylinder 5 is , It becomes impossible to be placed on the horizontal plane c7 ″ of the thick part c7. Accordingly, it is necessary to provide the anti-rotation rib c6 in the opposite direction on the locking annular body c3 constituting the core member C1.

  As described above, the locking projection 5c protruding from the locking cylinder 5 is formed on the horizontal surface c7 "of the thick portion c7 formed on the locking annular body c3 constituting the core member C1. In the mounted state, even if the core member C1 is lifted upward, the core member C1 is not pulled out of the fitting member 4, and this state is not pulled out. It is called possible state.

  As described above, after the core member C1 is attached to the container body B ′, the container body is inserted into the core member C1 by inserting the center hole w1 of the article W as shown in FIG. The article W is accommodated in B ′.

  As described above, in a state where the core member C1 cannot be pulled out, even if a load is applied to the core member C1 such that the core member C1 is pulled out from the fitting member 4 erected on the bottom 1, Since the locking projection 5c protruding from the locking cylinder 5 comes into contact with the locking annular body c3 constituting the core member C1, the core member C1 is pulled out of the fitting member 4. This can be reliably prevented. The load of pulling the core member C1 from the fitting member 4 standing on the bottom 1 is applied to the container body B by using an automatic machine such as a manual operation or a robot to remove the article inserted into the core member C1. When the core member C1 is pulled out due to such a load, there is nothing to support the article, so that the stacked or superposed article collapses and the article is damaged. It will be.

  In addition, the locking annular body c3 is formed on the inner wall surface near both ends of the core member C1, and the partition wall c2 is formed on the inner wall surface near the center of the core member C1. Therefore, it is possible to prevent dust and dirt from entering the core member C1, and therefore, dust and dirt that have entered the core member C1 are inserted into the core member C1 and attached to the article W. This can be prevented. Furthermore, when the core member C1 is attached to the container main body B ′, the core member C1 is positioned directly below the locking projection 5c formed as a through hole for a mold that is pulled downward from the back side of the bottom portion 1. Dust or dust may intrude into the core member C1 from the through hole 6 formed in the top plate 4b of the fitting member 4 to be formed. By forming the partition wall c2, the core member from the through hole 6 is formed. Intrusion of dust or dirt into C1 can be prevented.

  All the stored articles W are taken out from the container main body B ′, and the empty transport container B is returned to the article manufacturing factory, the article storage place, etc. In the case of a transport container that cannot be transported, the storage space of the transport container is large, and therefore the transport container B has low storage efficiency. However, the transport container B having the nestable container body B ′ as described above. In this case, in the nesting state, as shown in FIG. 13, there is a space between the bottom 1 of the container body Ba ′ positioned above and the bottom 1 of the container body Bb ′ positioned below. Part A2 will be formed. Accordingly, the locked state with the locking cylinder 5 is released, and the core member C1 pulled out from the fitting member 4 can be accommodated in the space A2 and a plurality of nesting can be provided. Since the overall height of the container main body B ′ can be reduced, the storage space for the transport container B having the empty container main body B ′ can be reduced, and therefore the empty container main body B The storage efficiency of the transport container B having 'can be improved.

  Furthermore, since the annular recess 1b is formed in the bottom 1 so as to surround the outer peripheral side surface 4a1 of the cylindrical support 4a, it is located at the bottom of the articles inserted into the core member C1. The lower surface w2 and the center hole w1 positioned in the vicinity of the core member C1 of the article W1 do not contact the vicinity of the end surface c14 of the core member C1, and the lower surface w2 of the article W1 positioned at the bottom is other than the annular recess 1b. It is placed on the flat upper surface 1a of the bottom 1 located. By the way, the semi-cylindrical core C1 ′ constituting the core member C1 is integrally formed by injection molding, but burrs are formed on the end surface of the integrally-formed semi-cylindrical core C1 ′. Sometimes. When the annular recess 1b is not formed on the bottom 1 and the end surface c14 of the core member C1 is placed on the flat upper surface 1a of the bottom 1, the lower surface w2 and center of the article W1 positioned at the bottom The burr may come into contact with the hole w1, and the article W1 positioned at the bottom may be damaged. However, in this embodiment, the burr formed on the end surface of the integrally formed semicylindrical core C1 ′ is formed between the upper surface 1b1 of the annular recess 1b and the article W1 positioned at the bottom. Since it will be located in space part A3, a burr | flash does not contact | abut to the lower surface w2 and center hole w1 located in the core member C1 vicinity of the article W1 located in the lowest, Therefore, semi-cylindrical shape The burr formed on the end face of the core body C1 ′ can prevent the article W1 positioned at the bottom from being damaged.

  Next, another embodiment will be described with reference to FIGS.

  In this embodiment, the locking cylinder 5 standing on the top plate 4b of the fitting member 4 formed on the bottom 1 of the container body B 'is omitted, and the bottom 1 is fitted. Only the member 4 is formed.

  A locking female member 10 is formed on the upper surface 1 b 1 of the annular recess 1 b along the outer peripheral side surface 4 a 1 of the cylindrical support 4 a of the fitting member 4. The locking female member 10 is erected on the upper surface 1b1 of the annular recess 1b and is curved from the side wall 10a curved along the outer peripheral side surface 4a1 of the cylindrical support 4a, and the upper end of the side wall 10a. An end that extends in the direction of the outer peripheral side surface 4a1 and is curved along the outer peripheral side surface 4a1 of the cylindrical support 4a, and an end that connects one vertical end of the side wall 10a and one vertical end of the top plate 10b. And a wall 10c.

  Moreover, the top plate 10b is not in contact with the outer peripheral side surface 4a1 of the cylindrical support 4a, the edge 10b 'on the cylindrical support 4a side of the top plate 10b and the outer peripheral side surface 4a1 of the cylindrical support 4a. A gap that is slightly wider than the thickness of the semi-cylindrical body c1 ′ constituting the fitting space A1 of the core member C2 of this embodiment is formed between them. In addition, 11 is a through hole formed in the annular recess 1b located directly below the top plate 10b of the locking female member 10, and is a removal for a mold that is pulled down to form the top plate 10b. It is a through hole.

  As described above, the locking female member 10 has the side wall 10a, the top plate 10b, and the end wall 10c, and the lower portion of the locking female member 10 is a through hole that is a through hole for a mold. 11 is formed, and a locking male projection insertion opening 10d is formed on the opposite side of the end wall 10c. Further, the lower surface 10b1 of the top plate 10b includes a guide inclined surface portion 10b1 'inclined downward from the locking male projection insertion opening 10d toward the end wall 10c, and a locking position plane portion 10b1 "positioned near the end wall 10c". And have.

  One of the differences between the core member C2 in the present embodiment and the core member C1 in the above-described embodiment is that, in the core member C2, the semicylindrical body c1 ′ constituting the core member C2 has a locking semi-annular shape. The body c3 is not formed, and instead of the locking semi-annular body c3, a partition wall c2 is formed. Therefore, in the core member C2 in this embodiment, four partition walls c2 are formed. ing. Another difference of the core member C2 in the present embodiment from the core member C1 in the above-described embodiment is that the semicylindrical body c1 ′ is formed on one end surface of the semicylindrical body c1 ′ constituting the core member C2. A flat male protrusion 5c ′ perpendicular to the outer peripheral surface of the plate is formed. The thickness of the locking male projection 5c ′ is formed between the lower surface 10b1 and the upper surface 1b of the annular recess 1b on the top plate 10b positioned in the back of the locking member 10 (located in the vicinity of the end wall 10c). It is formed approximately the same as the gap.

  In order to attach the core member C2 to the fitting member 4 of the container body B ′, first, it is formed between the end surface c14 of the core member C2 and the partition wall c2 formed in place of the locking annular body c3. The cylindrical support 4a that constitutes the fitting member 4 erected on the bottom 1 is fitted into the fitting space A1, and the core member C2 is rotated so that the outer peripheral surface of the core member C2 is rotated. The protruding locking male protrusion 5 c ′ is inserted into the locking male protrusion insertion opening 10 d of the locking female member 10. When the core member C2 is further rotated from this state, the locking male protrusion 5c ′ moves in the direction of the end wall 10c along the guide inclined surface portion 10b1 ′ of the locking female member 10, and finally, FIG. As shown in FIG. 22, the locking male projection 5c ′ is fitted into a gap T1 formed between the locking position flat surface portion 10b1 ″ of the locking female member 10 and the upper surface 1b1 of the annular recess 1b. Note that when the locking male projection 5c ′ contacts the end wall 10c of the locking female member 10, the further rotation of the core member C2 is stopped.

  As described above, the locking male projection 5c ′ formed on the core member C2 has an annular shape with the locking position plane portion 10b1 ″ of the locking female member 10 formed on the upper surface 1b1 of the annular recess 1b of the container body B ′. When the core member C2 is lifted upward when inserted into the gap T1 formed between the upper surface 1b1 of the recess 1b, the core member C2 is not pulled out of the fitting member 4 The member C2 is in a state where it cannot be pulled out.

  Note that the locking male projection 5c ′ formed on the core member C2 from the above-described state where the core member C2 cannot be pulled out is the locking male projection insertion opening of the locking female member 10 formed on the container body B ′. By rotating the core member C2 so as to move in the 10d direction, the locking male protrusion 5c ′ formed on the core member C2 is discharged from the locking male protrusion insertion opening 10d of the locking female member 10, The core member C2 can be lifted upward, and the core member C2 can be pulled out of the fitting member 4.

  In the embodiment described above, an example is shown in which one locking male protrusion 5c ′ is formed at each end of the core member C2, but a plurality of locking male protrusions 5c ′ are formed at one end of the core member C2. It can also be formed. Thus, when a plurality of locking male protrusions 5c ′ are formed at one end of the core member C2, a plurality of engagements are provided on the container body B ′ corresponding to the locking male protrusions 5c ′. The stop female member 10 is formed.

  In this embodiment, instead of the locking semi-annular body c3 ′ formed with the over-rotation preventing rib c5, the opposite direction anti-rotation rib c6, and the thick body c7, a flat plate-shaped partition semicircle c2 ′ is used. Therefore, the configuration of the core member C2 is simplified as compared with the above-described core member C1, and therefore the manufacturing cost of the core member C2 can be reduced.

  Further, in this embodiment, instead of the locking semi-annular body c3 ′, a flat plate-shaped partition semicircular body c2 ′ is formed, so that both ends of the core member C2 are for the locking cylinder. Instead of the locking annular body c3 having the insertion hole c4a, a partition wall c2 in which such a locking cylinder insertion hole c4a is not formed is located, and accordingly, dust into the core member C2 is located. Invasion of dust and the like can be reliably prevented.
