  By the way, regarding the lid member, it is difficult to visually recognize all the locking portions formed on the lower surface of the lid member when the sleeve is covered. For this reason, for example, when the width of the groove formed for inserting the sleeve in the locking portion is substantially the same as the thickness of the sleeve, there is a concern that the operation of covering the cover member on the sleeve may be hindered.

  On the other hand, when the groove width of the locking portion is relatively wide compared to the thickness of the sleeve, the workability of covering the cover member on the sleeve can be improved, but the cover member does not rattle against the sleeve. There is a concern that this may occur easily or the sleeve configured to be foldable may be inadvertently deformed.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a lid member capable of stabilizing the mounting state while improving workability when being put on a sleeve. There is.

  In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to a corresponding means are added as needed.

Means 1. A lid member that covers a foldable sleeve in the shape of a square cylinder that is erected on a base member on which an article can be placed,
With a substantially rectangular plate-like lid body capable of closing the opening above the sleeve,
On the lower surface side of the lid body, there is provided a groove constituting portion that is formed along the outer peripheral edge of the lid body and into which the upper side portion of the sleeve can be inserted,
The groove constituting portion includes an outer wall portion and an inner wall portion that face each other in the outer peripheral direction of the lid body, and a support wall portion that connects the upper side portion of the outer wall portion and the inner wall portion, and has a substantially U-shaped cross section that opens downward. Shape
Corresponding to at least two opposing side portions of the lid body, a guide rib extending from the inner peripheral surface of the lid body of the inner wall portion is provided,
The lid member is characterized in that the lower side portion of the guide rib is inclined upward toward the outer peripheral side of the lid body and is connected to the lower side portion of the inner wall portion.

  According to the means 1, on the lower surface side of the lid main body, the guide rib whose lower side portion is inclined upward toward the outer peripheral side of the lid main body is provided on the inner peripheral side of the lid main body with respect to the groove constituting portion. The lower side portion is connected to the lower side portion of the inner wall portion of the groove constituting portion. For this reason, the upper side portion of the sleeve and the lower side portion of the guide rib of the lid member are in contact with each other, so that the upper side portion of the sleeve is relatively guided by the guide rib toward the lower side portion of the inner wall portion and thus inside the groove constituting portion. It becomes easy. Accordingly, when the cover member is put on the sleeve, even if the horizontal position of the upper side portion of the sleeve and the groove constituting portion of the cover member is displaced, the upper side portion of the sleeve and the lower side portion of the guide rib of the cover member are If it is in a contact state, the upper side portion of the sleeve can be inserted into the groove constituting portion of the lid member relatively smoothly. As a result, it is possible to improve workability when the cover member is put on the sleeve.

  Moreover, the groove | channel structure part is provided with not only the outer wall part but the inner wall part. For this reason, the deformation of the sleeve inserted into the groove constituting portion can be restricted by the outer wall portion and the inner wall portion, and the situation where the sleeve is accidentally folded can be prevented more reliably. Further, by providing the guide rib as described above, the width of the groove component (the distance between the outer wall portion and the inner wall portion) can be reduced while avoiding deterioration in workability when the cover member is put on the sleeve. Can do. Therefore, the effect of preventing the sleeve from being deformed between the outer wall portion and the inner wall portion can be more reliably achieved, and rattling of the lid member with respect to the sleeve in the horizontal direction can be more reliably prevented. As a result, it is possible to stabilize the mounting state of the lid member, and thus the state in which the base member, the sleeve, and the lid member are assembled into a box-shaped container.

  The lower side portion of the inner wall portion may be formed obliquely so as to be flush with the lower side portion of the guide rib. In this case, the sleeve in contact with the guide rib can be guided relatively smoothly to the groove constituting portion. Further, instead of “corresponding to at least two opposing side portions of the lid body”, “corresponding to four side portions of the lid body” may be used. In this case, the guiding effect when the cover member is put on the sleeve is further enhanced.

Mean 2. The upper surface side of the lid body is provided with a protruding portion that protrudes upward from the upper surface of the lid body at a position above the guide rib,
When the lid members are stacked one above the other and the outer peripheral edges of the lid members stacked one above the other are aligned, the protruding portion of the lower lid member is connected to the lower side portion of the guide rib of the upper lid member and the outer wall. The lid member according to claim 1, wherein the lid member is accommodated in a space between the first member and the second member.

  According to the means 2, the protrusion is provided on the upper surface side of the lid member, and when the lid members are stacked vertically (stacked), the protrusion of the lower lid member becomes the upper lid member. It is accommodated in a space between the lower side of the guide rib and the outer wall. Therefore, when stacking the lid members, it is not necessary to separately form a recess for inserting and locking the protruding portion of the lower lid member. It is possible to prevent a situation where the member falls off the lower lid member.

  Further, when the lid members are stacked, even if the horizontal positions of the upper and lower lid members are shifted, the upper surface of the protruding portion of the lower lid member and the lower side portion of the guide rib of the upper lid member are If the upper cover member is inclined, the protruding portion of the lower cover member is relatively positioned in the space between the lower side portion of the guide rib of the upper cover member and the outer wall portion. It becomes easy to be guided to. For this reason, the outer periphery of a cover member can be aligned comparatively smoothly. As a result, it is possible to improve workability when stacking the lid members.

  In addition, it is good also as "the upper surface of the said protrusion part is comprised so that the same inclination angle as the lower side part of the said guide rib may be made." In this case, no matter which part of the upper surface of the protruding portion of the lower lid member abuts on the lower side portion of the guide rib of the upper lid member, the protruding portion of the lower lid member is the lower side of the guide rib of the upper lid member. It becomes easy to guide relatively to the space between the part and the outer wall part. For this reason, when the lid members are stacked one above the other, the guidance effect can be obtained even when the lid members are largely displaced in the horizontal direction. Therefore, the workability at the time of stacking the lid members can be further improved.

Means 3. The upper surface of the lid body is provided with an installation portion that supports the supporting leg portions protruding downward from a plurality of locations on the lower surface of the base member, and that can regulate the movement of the supporting leg portions in the horizontal direction.
The lid member according to means 2, wherein the installation part is formed adjacent to the projection part, and an upper surface of the projection part is inclined downward toward the installation part side.

  According to the means 3, the upper surface of the protrusion is inclined downward toward the installation part adjacent to the protrusion. Therefore, when the base member is stacked on the upper side of the lid member, even if the horizontal position of the installation portion of the lid member and the support leg portion of the base member is shifted, the upper surface of the protruding portion of the lid member and the base member If the lower surface of the support leg portion is in contact with the support leg portion, the support leg portion is easily guided to the installation portion side by the upper surface of the protruding portion. For this reason, the support leg portion of the base member can be installed on the installation portion of the lid member relatively smoothly. As a result, the workability when the base member is stacked on the lid member can be improved.

It is a partial expanded sectional view of FIG. It is a perspective view which shows the state which mounted the cover member on the pallet.

  Hereinafter, an embodiment will be described with reference to the drawings. As shown in FIG. 1, the assembly-type container 1 includes a pallet 2 as a base member on which an article can be placed, a square cylindrical sleeve 3 erected on the upper surface side of the pallet 2, and an upper part of the sleeve 3. And a lid member 4 that covers the sleeve 3 so as to close the opening. When an article is transported using the assembly type container 1, the outer periphery of the article placed on the pallet 2 is held by the sleeve 3, so that the article is prevented from falling off and placed on the pallet 2. Since the covered article is covered and protected by the sleeve 3 and the lid member 4, damage to the article is prevented.

  The pallet 2 includes a substantially rectangular plate-like deck 11 on which articles are placed, and a support leg 12 that protrudes downward from the lower surface of the deck 11 and supports the upper surface of the deck 11 substantially parallel to the installation surface (floor surface). I have. The support legs 12 are provided at the four corners of the deck 11, the intermediate position of the side of the deck 11, and the center of the deck 11. Between the support legs 12, a forklift or a hand lift (not shown) is provided. A gap (fork insertion portion) into which the fork can be inserted is formed.

  Further, on the upper surface side of the deck 11, a base side groove constituting portion 13 for supporting and standing the square cylindrical sleeve 3 is formed along the outer peripheral edge of the deck 11. And the sleeve 3 is supported by the pallet 2 and the horizontal displacement is prevented by inserting the lower side portion of the sleeve 3 into the base side groove constituting portion 13 having a substantially U-shaped cross section opening upward. It will be.

  The sleeve 3 includes four side wall portions 21 so as to form a rectangular tube shape, and the side wall portions 21 are connected to each other via a hinge portion (not shown). Further, the pair of opposing side wall portions 21 among the four side wall portions 21 is configured by two plate-like bodies 23 arranged on the left and right sides being flexibly connected by a hinge portion (not shown). With this configuration, the sleeve 3 can be folded so that the side wall portion 21 formed by the two plate-like bodies 23 is folded inward.

  The lid member 4 includes a substantially rectangular plate-like lid body 31 that can close the opening above the sleeve 3, and on the lower surface side of the lid body 31 on the outer peripheral edge of the lid body 31 as shown in FIG. 2. A lid side groove constituting portion 32 that is formed along the upper side portion of the sleeve 3 can be inserted. As shown in FIG. 3 and the like, the lid-side groove constituting part 32 includes a support wall part that connects the outer wall part 33 and the inner wall part 34 that face each other in the outer peripheral direction of the lid body 31 and the upper side part of the outer wall part 33 and the inner wall part 34. 34, and has a substantially U-shaped cross section that opens downward. The width of the support wall 34 (the distance between the outer wall 33 and the inner wall 34) of the lid side groove constituting part 32 is configured to be slightly larger than the thickness of the sleeve 3. The lid member 4 of this embodiment is integrally formed of polypropylene by molding.

  As shown in FIGS. 2, 3, and the like, reinforcing ribs 37 extending in a lattice shape are formed on the lower surface side of the lid body 31 in parallel with the side portions of the lid body 31. In the present embodiment, since the lid-side groove constituting portion 32 is continuously formed on the lower surface of the lid main body 31 over the entire circumference of the outer peripheral edge, the reinforcing rib 37 is more than the lid-side groove constituting portion 32. Is provided on the inner peripheral side.

  Further, as shown in FIGS. 3, 4, etc., in the present embodiment, a rib (hereinafter referred to as an “adjacent rib”) that faces the lid-side groove constituting portion 32 as a portion of the reinforcing rib 37 that is positioned closest to the outer peripheral side of the lid member 4. 38 ”), a guide rib 39 is provided to connect the inner wall portion 34 of the lid side groove constituting portion 32. The lower side portion of the guide rib 39 is connected to the lower side portion of the adjacent rib 38 and the lower side portion of the inner wall portion 34. Further, the lower side portion of the inner wall portion 34 of the lid side groove constituting portion 32 is located above the lower side portion of the reinforcing rib 37 (adjacent rib 38), and the lower side portion of the guide rib 39 is on the outer peripheral side of the lid main body 31. It is inclined upward. Furthermore, the lower side portion (lower surface) of the inner wall portion 34 of the present embodiment is formed obliquely so as to be flush with the lower side portion of the guide rib 39.

  With this configuration, even when the position of the upper side portion of the sleeve 3 and the position of the lid side groove constituting portion 32 of the lid member 4 are slightly shifted in the horizontal direction during the operation of covering the sleeve 4 with the lid member 4, the upper side of the sleeve 3. Since the portion abuts against the lower side portion of the guide rib 39 of the lid member 4, the upper side portion of the sleeve 3 is relatively easily guided by the guide rib 39 toward the lid side groove constituting portion 32. For this reason, the cover member 4 can be covered on the sleeve 3 relatively easily.

  In addition, as shown in FIG. 2, the upper surface side of the lid body 31 is configured to be slidable in the outer peripheral direction of the lid body 31 at a pair of opposite side portions of the lid member 4. A lock member 41 capable of projecting inside 32 is provided. On the other hand, as shown in FIG. 1, a locking hole 25 penetrating in the thickness direction of the sleeve 3 is formed in a portion of the sleeve 3 to be inserted inside the lid side groove constituting portion 32. Then, in a state where the sleeve 3 is inserted into the lid-side groove constituting portion 32, the lock member 41 is protruded into the lid-side groove constituting portion 32, whereby the tip of the lock member 41 is inserted into the locking hole 25 of the sleeve 3. . As a result, the sleeve 3 and the lid member 4 are fixed, and the falling off of the lid member 4 is more reliably prevented.

  Although not shown in the drawings, the pallet 2 is also provided with a lock member that can project inside the foundation side groove constituting portion 13, and the lock member is inserted into the locking hole 25 at the lower portion of the sleeve 3. Thus, the pallet 2 and the sleeve 3 are fixed, and the sleeve 3 is more reliably prevented from falling off. Further, the outer peripheral shape of the lid main body 31 of the lid member 4 and the outer peripheral shape of the deck 11 of the pallet 2 are the same, and the lid member 4 is directly placed on the upper side of the pallet 2 as shown in FIG. It is also possible. In this case, positioning ribs 42 provided by partially extending the outer wall portion 33 of the lid side groove constituting portion 32 of the lid member 4 downwardly formed on the base side groove constituting portion 13 (outer wall portion) of the pallet 2. It is inserted into the positioning recess 15 thus prevented from being displaced in the horizontal direction.

  As shown in FIGS. 1, 3, and the like, a protrusion 43 that protrudes upward from the upper surface of the lid body 31 is provided on the upper surface side of the lid body 31 at a position above the guide rib 39. As shown in FIG. 4 and the like, the protrusion 43 has an outer plate portion 44 formed so as to extend the inner wall portion 34 of the lid-side groove constituting portion 32 to the upper surface side of the lid main body 31, and more than the outer plate portion 44. An inner plate 45 located on the inner peripheral side of the lid body 31 and facing the outer plate 44 with a predetermined distance therebetween, and an upper plate 46 connecting the outer plate 44 and the upper side of the inner plate 45. And. The outer plate portion 44 extends upward from the inner plate portion 45, and the upper plate portion 46 constituting the upper surface of the protruding portion 43 is inclined downward toward the inner peripheral side of the lid body 31. In particular, in this embodiment, the inclination angle of the lower side portion of the guide rib 39 is the same as the inclination angle of the upper plate portion 46 of the protruding portion 43 positioned above the guide rib 39. Further, the inner plate portion 45 is located on the outer peripheral side of the lid main body 31 with respect to the adjacent rib 38.

  With this configuration, as shown in FIG. 5, when the lid members 4 are stacked up and down (stacked) with their outer peripheral edges aligned, the protrusion 43 of the lower lid member 4 becomes the upper lid. The member 4 is accommodated in a space between the adjacent rib 38 of the member 4 and the outer wall portion 33, more specifically, a space between the lower side portion of the guide rib 39 and the outer wall portion 33. In addition, when stacking the lid members 4 together, even if the horizontal positions of the upper and lower lid members 4 are slightly shifted, the upper surface of the protruding portion 43 of the lower lid member 4 remains on the upper lid member 4. By contacting the inclined lower side portion of the guide rib 39, the protruding portion 43 of the lower lid member 4 is relatively moved toward the lid-side groove constituting portion 32 side of the upper lid member 4 by the guide rib 39 of the upper lid member 4. It becomes easy to be guided. For this reason, the lid members 4 can be stacked relatively easily.

  In the present embodiment, the positions of the inner wall portion 34 of the lid side groove constituting portion 32 and the outer plate portion 44 of the protruding portion 43 are aligned in the outer peripheral direction of the lid main body 31. Therefore, when the lid members 4 are stacked, the outer plate portion 44 of the protruding portion 43 of the lower lid member 4 and the inner surface of the outer wall portion 33 of the lid-side groove constituting portion 32 of the upper lid member 4 are arranged. A relatively large gap is formed. In this respect, in this embodiment, a backlash rib 47 that protrudes from the outer surface of the outer plate portion 44 to the outer peripheral side of the lid body 31 is provided, and the backlash rib 47 can narrow the gap, and the lid member 4. It is possible to suppress misalignment between them.

  In the present embodiment, when the lid members 4 are stacked, the entire protrusion 43 of the lower lid member 4 becomes adjacent to the adjacent rib 38 (lower side portion of the guide rib 39) and the outer wall portion 33 of the upper lid member 4. The upper surface of the lid main body 31 of the lower lid member 4 and the lower side portion of the reinforcing rib 37 of the upper lid member 4 are in contact with each other. For this reason, the height of the stacked lid members 4 as a whole can be suppressed. Furthermore, in the present embodiment, the lower edge portion of the lid-side groove constituting portion 32 (outer wall portion 33) is basically located above the lower side portion of the reinforcing rib 37, and a portion (positioning rib) that protrudes greatly downward. 42), the height is the same as the lower side of the reinforcing rib 37. Thereby, the area (grounding area | region) which supports lid member 4 itself can be increased, and suppression of a deformation | transformation (plastic deformation) etc. of the lid member 4 can be aimed at.

  In the lid member 4 of the present embodiment, the accommodating portion 48 (see FIG. 1) for accommodating the lock member 41 protrudes from the lower side portion of the guide rib 39 to the outer peripheral side of the lid main body 31 (FIG. 2). reference). For this reason, the function of relatively guiding the upper side portion of the sleeve 3 by the guide rib 39 does not sufficiently act on the pair of opposing side portions of the lid member 4 provided with the storage portion 48, but the storage portion 48. The guide effect of the sleeve 3 by the guide ribs 39 is reliably achieved at the pair of opposing side portions of the lid member 4 where no cover is provided. Further, when the cover member 4 is put on the sleeve 3, the side portion of the cover member 4 where the lock member 41 is not provided is made to correspond to the side wall portion 21 formed of the two plate-like bodies 23 of the sleeve 3. It is desirable. That is, even if the side wall portion 21 is slightly bent, the side wall portion 21 is naturally straightened by being fitted into the lid side groove constituting portion 32 while guiding the upper side portion of the side wall portion 21 with the guide rib 39 of the lid member 4. Therefore, when the cover member 4 is covered, it is not necessary to hold the side wall portion 21 formed by the two plate-like bodies 23 so as to extend straight, thereby improving workability.

  Furthermore, in the present embodiment, the protruding portion 43 provided on the upper surface side of the lid member 4 is not provided at a position where the lock member 41, and thus the accommodation portion 48 is provided. For this reason, when the lid members 4 are stacked, the protrusions 43 of the lower lid member 4 are relatively guided by the guide ribs 39 of the upper lid member 4 in all the side portions of the lid member 4. An effect is produced.

  Further, as shown in FIGS. 6 and 7, in the present embodiment, the pallet 2 can be directly placed on the upper surface of the lid member 4, and the pallet 2 is covered on the upper surface of the lid member 4. An installation recess 49 (see FIG. 1 and the like) is formed as an installation part that is recessed in a square shape at a position that supports the support leg part 12 of the pallet 2 when placed on the member 4 with the outer peripheral edge aligned. . The support legs 12 of the pallet 2 are inserted into and supported by the installation recesses 49 of the lid member 4 so that the position shift of each support leg 12 in the horizontal direction is prevented.

  Further, the protruding portion 43 is provided adjacent to a side portion extending along the outer peripheral edge of the lid main body 31 in the installation concave portion 49. In other words, the installation concave portion 49 is provided adjacent to the inner plate portion 45 of the protruding portion 43. Further, as described above, since the upper surface of the protrusion 43 is inclined downward toward the inner peripheral side of the lid body 31, the installation recess 49 is placed when the pallet 2 is placed on the upper side of the lid member 4. Even if the support leg 12 is slightly displaced in the horizontal direction, the lower surface of the support leg 12 abuts on the upper surface of the protrusion 43 so that the support leg 12 is guided to the installation recess 49 by the upper surface of the protrusion 43. It becomes easy to be done. For this reason, the pallet 2 can be mounted on the lid member 4 relatively easily.

  As described in detail above, according to the present embodiment, the lower side of the lid body 31 faces the outer peripheral side of the lid body 31 on the inner circumferential side of the lid body 31 relative to the lid-side groove constituting portion 32 on the lower surface side of the lid body 31. A guide rib 39 that is inclined upward is provided, and the lower side portion of the guide rib 39 is connected to the lower side portion of the inner wall portion 34 of the lid-side groove constituting portion 32. For this reason, the upper side portion of the sleeve 3 and the lower side portion of the guide rib 39 of the lid member 4 come into contact with each other, whereby the upper side portion of the sleeve 3 is relatively moved by the guide rib 39 to the lower side portion of the inner wall portion 34, and thus the lid side groove. It becomes easy to be guided inside the component 32. Accordingly, when the cover member 4 is put on the sleeve 3, even if the horizontal position of the upper side portion of the sleeve 3 and the cover side groove constituting portion 32 of the cover member 4 is shifted, the upper side portion of the sleeve 3 and the cover member If the lower side portion of the four guide ribs 39 is in contact, the upper side portion of the sleeve 3 can be inserted into the lid side groove constituting portion 32 of the lid member 4 relatively smoothly. In particular, in this embodiment, since the lower side portion of the inner wall portion 34 is formed obliquely so as to be flush with the lower side portion of the guide rib 39, the sleeve 3 that is in contact with the guide rib 39 is more smoothly covered with the lid side groove constituting portion. 32 can be guided relatively. As a result, it is possible to improve workability when the cover member 4 is put on the sleeve 3.

  The lid-side groove constituting portion 32 includes not only the outer wall portion 33 but also the inner wall portion 34 (over the entire circumference of the outer peripheral edge of the lid main body 31). For this reason, the deformation of the sleeve 3 inserted into the lid-side groove constituting portion 32 can be restricted by the outer wall portion 33 and the inner wall portion 34, and the situation where the sleeve 3 is accidentally folded can be prevented more reliably. be able to. Furthermore, by providing the guide rib 39 as described above, it is possible to avoid a reduction in workability when the cover member 4 is put on the sleeve 3, while reducing the width of the cover side groove constituting portion 32 (the outer wall portion 33 and the inner wall portion 34. (Distance between them) can be reduced (in this example, equivalent to the thickness of the side wall 21 of the sleeve 3). Therefore, the outer wall portion 33 and the inner wall portion 34 can more reliably prevent the sleeve 3 from being deformed, and more reliably prevent the cover member 4 from rattling in the horizontal direction with respect to the sleeve 3. . As a result, it is possible to stabilize the mounted state of the lid member 4, that is, the state in which the pallet 2, the sleeve 3, and the lid member 4 are assembled to form the assemblable container 1.

  Further, a protrusion 43 is provided on the upper surface side of the lid member 4, and when the lid members 4 are stacked, the protrusion 43 of the lower lid member 4 is adjacent to the adjacent rib 38 of the upper lid member 4. It is accommodated in a space between the (lower side portion of the guide rib 39) and the outer wall portion 33. For this reason, when stacking the lid members 4 together, it is not necessary to separately form a recess for inserting and locking the protruding portion 43 of the lower lid member 4, while suppressing the complexity of the configuration, It is possible to prevent a situation in which the upper lid member 4 falls off the lower lid member 4.

  Further, when the lid members 4 are stacked, even if the horizontal positions of the upper and lower lid members 4 are shifted, the upper surface of the protrusion 43 of the lower lid member 4 and the guide ribs of the upper lid member 4 If the lower side portion of the upper cover member 4 is in contact, the inclined guide rib 39 of the upper cover member 4 causes the protruding portion 43 of the lower cover member 4 to contact the adjacent rib 38 of the upper cover member 4. It becomes easy to be guided relatively to the space between the outer wall portion 33. For this reason, the outer periphery of the cover member 4 can be aligned relatively smoothly. As a result, it is possible to improve workability when stacking the lid members 4 together.

  In addition, the upper surface of the protrusion 43 is configured to have the same inclination angle as the lower side of the guide rib 39. For this reason, even if the upper surface of the protruding portion 43 of the lower lid member 4 and the lower side portion of the adjacent rib 38 of the upper lid member 4 are in contact, the protruding portion 43 of the lower lid member 4 is It becomes easy to be guided relatively to the space between the adjacent rib 38 of the lid member 4 and the outer wall portion 33. For this reason, when the lid members 4 are stacked one above the other, the guidance effect can be obtained even when the lid members 4 are largely displaced in the horizontal direction. Therefore, the workability at the time of stacking the lid members 4 can be further improved. Furthermore, it is possible to increase the contact area between the upper surface of the protruding portion 43 of the lower lid member 4 and the lower side portion of the guide rib 39 of the upper lid member 4. Can be suppressed.

  Further, the upper surface of the protruding portion 43 is formed to have the same inclination angle as the lower side portion of the guide rib 39, thereby forming an inclined surface that is inclined downward toward the inner peripheral side of the lid main body 31. Further, an installation recess 49 is provided adjacent to the inner peripheral side of the lid body 31 of the protrusion 43. Therefore, when the pallet 2 is stacked on the upper side of the lid member 4, even if the horizontal position between the installation concave portion 49 of the lid member 4 and the support leg portion 12 of the pallet 2 is shifted, the protrusion 43 of the lid member 4 If the upper surface and the lower surface of the support leg portion 12 of the pallet 2 are in contact with each other, the support leg portion 12 is easily guided to the installation recess 49 side by the upper surface of the protruding portion 43. For this reason, the support leg 12 of the pallet 2 can be installed in the installation recess 49 of the lid member 4 relatively smoothly. As a result, the workability when the pallet 2 is stacked on the lid member 4 can be improved.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the above embodiment, the locking hole 25 for locking the tip of the locking member 41 is formed in the sleeve 3, but the configuration for engaging the upper portion of the sleeve 3 and the lid member 4 is particularly limited. Is not to be done. For example, the locking hole 25 may be omitted, or a recess may be formed in place of the locking hole 25 so that the locking member 41 is pressed against the sleeve 3 to prevent the sleeve 3 from falling off. May be. In addition, the lock member 41 can be omitted.

  Moreover, in the said embodiment, although the accommodating part 48 for accommodating the locking member 41 protrudes in the outer peripheral side of the cover main body 31 rather than the lower side part of the guide rib 39 extended diagonally, it is comprised so that it may not protrude. Also good. In this case, it is necessary to displace the lock member 41 larger than that in the above-described embodiment in order to cause the lock member 41 to appear inside and outside the lid-side groove constituting portion 32, but when the cover member 4 is put on the sleeve 3, the lock member 41 Also with respect to the side portion of the lid member 4 provided with 41, the guiding effect due to the inclination of the lower side portion of the guide rib 39 can be enjoyed, and the workability when the lid member 4 is put on the sleeve 3 is further improved. Can be planned. In addition, the said effect is show | played similarly when the lock member 41 and the accommodating part 48 are abbreviate | omitted.

  (B) In the above embodiment, on the upper surface of the lid main body 31, when the pallet 2 is placed on the lid member 4, the lid of the part where the fulcrum part 12 is installed as the installation part that contacts and supports the fulcrum part 12 The installation concave portion 49 is formed by denting the upper surface of the main body 31 downward. That is, if the protrusions 43 are provided at a plurality of locations adjacent to the portion where the support leg 12 is installed as in the above-described embodiment, the position shift of the support leg 12 is caused by the inner plate part 45 of the protrusion 43. Can be regulated. Of course, by forming the installation recess 49 as in the above embodiment, it is possible to more reliably prevent the displacement of the pallet 2 placed on the lid member 4.

  (C) In the above embodiment, the width of the support wall portion 34 of the lid side groove constituting portion 32 is configured to be slightly larger than the thickness of the sleeve 3, but may be larger than the above embodiment. However, from the viewpoint of positioning the sleeve 3 (preventing displacement in the horizontal direction), it is desirable that the sleeve 3 be configured as narrow as possible (a little larger than the thickness of the sleeve 3).

  Moreover, in the said embodiment, although the position of the outer-plate part 44 of the protrusion part 43 and the position of the inner wall part 34 of the cover side groove | channel structure part 32 are the same in the outer peripheral direction of the lid | cover main body 31, especially like this It is not limited to a simple configuration. That is, the outer plate portion 44 is positioned on the inner peripheral side of the lid main body 31 with respect to the outer wall portion 33, the inner plate portion 45 is positioned on the outer peripheral side of the lid main body 31 with respect to the adjacent rib 38, and the lid members 4 are stacked. In this case, the protruding portion 43 of the lower lid member 4 only needs to be accommodated between the outer wall portion 33 of the upper lid member 4 and the adjacent rib 38. For example, the outer plate portion 44 of the protruding portion 43 is positioned on the outer peripheral side of the lid main body 31 with respect to the inner wall portion 34 of the lid-side groove constituting portion 32, and the protruding portion 43 is opened upward (the upper plate portion 46 is omitted). Instead, a rib for connecting the outer plate portion 44 and the inner plate portion 45 may be provided).

  Furthermore, in the said embodiment, although the upper surface of the protrusion part 43 becomes the inclined surface of the same angle as the inclination angle of the lower side part of the guide rib 39, an inclination angle may differ. That is, even when the inclination of the upper surface of the protruding portion 43 is different (for example, a horizontal surface), when the lid members 4 are stacked, the upper surface of the protruding portion 43 of the lower lid member 4 is If it contacts the lower side portion of the guide rib 39 of the lid member 4, the guiding effect is similarly obtained. Further, as long as the upper surface of the protruding portion 43 is inclined downward toward the adjacent installation concave portion 49, a guiding effect when the pallet 2 is placed on the lid member 4 is exhibited.

  (D) In the above embodiment, the pallet 2 provided with the support legs 12 is employed as the base member, but the configuration of the base member is not particularly limited. For example, the support legs 12 are omitted. A simple base member may be employed. Further, the number of the support leg portions 12 of the pallet 2 is not particularly limited, and may be provided at least at the four corners of the deck 11. Further, the sleeve 3 of the above embodiment has a configuration that can be folded by folding the side wall portion 21 including the two plate-like bodies 23 inward, and each of the sleeves 3 is constituted by one plate-like body. The four side wall portions 21 may be configured to be foldable so that a predetermined corner portion and a diagonal corner portion are brought close to each other by hinge-connecting the four side wall portions 21 to each other.

  (E) In the above embodiment, the lid member 4 is made of polypropylene, but may be made of other resin materials such as polyethylene, PET, and polyamide.
