A plurality of extending reinforcing ribs are provided side by side in the width direction of the entrance of the fork insertion portion, and the outer side of the lid member of the reinforcing rib is placed upward (when the packing unit is stacked, the fork insertion of the upper packaging unit is performed) There is a technique of inclining toward the inner side of the lid member (see, for example, Patent Document 1).

JP 2004-10129 A

  By the way, among the plurality of reinforcing ribs provided on the lid member of Patent Document 1, the reinforcing rib alone does not have such strength. For this reason, when the fork of a forklift contacts the plurality of reinforcing ribs, the reinforcing ribs themselves may be damaged depending on the relative angle and position of the fork with respect to each reinforcing rib.

  The present invention has been made in order to solve the above-described problems and the like, and the object thereof is a lid that can be used in a form combined with a pallet and can improve durability. It is to provide a member.

  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 the means to respond | correspond as needed are added.

Means 1. A lid member constituting a packing unit in which an article placed on a pallet is covered with a lid member,
A top wall having a substantially rectangular shape in plan view;
An outer wall portion extending downward from each side portion of the top wall portion, and
A plurality of reinforcing ribs projecting downward from the top wall portion and connecting the outer wall portions on the inner peripheral side of the outer wall portion;
When the packing units are stacked, in a portion arranged below the fork insertion part of the pallet of the upper packing unit, the boundary between the top wall part and the outer wall part is the top wall part, It is composed of an inclined wall part that is obliquely connected to the outer wall part,
A lid member comprising a reinforcing rib for connecting an inner surface of the inclined wall portion and the reinforcing rib.

  According to the means 1, when the fork lift fork is inserted into the fork insertion portion of the pallet in the case where the upper packing unit among the stacked packing units is sequentially transported by the fork lift, the fork tip is attached to the lid member. When the inclined wall portion comes into contact, all of the ribs connected to the inner side surface of the inclined wall portion (and the top wall portion) cooperate to support the inclined wall portion. That is, the impact of the fork coming into contact with the lid member can be distributed to all the ribs (and the top wall) connected to the inclined wall portion via the inclined wall portion. Can be prevented from being damaged or deformed. Therefore, the durability of the lid member can be improved. In particular, according to the present means 1, not only the reinforcing rib but also the reinforcing rib can be connected to the section of the outer wall portion where the inclined wall portion is provided in the circumferential direction of the lid member. Therefore, as compared with the case where the ribs provided on the lid member increase as a whole, the weight of the lid member is suppressed, and the pitch of the ribs supporting the inclined wall portion in contact with the fork as described above is more dense. The effect which prevents the deformation | transformation etc. of a contact site | part can be show | played further.

  Further, the fork of the forklift contacting the inclined wall portion is guided to the fork insertion portion side due to the inclination of the inclined wall portion (the fork can be released to the fork insertion portion side). The effect of preventing the damage of the contact part with the head is more remarkable.

  The “reinforcing ribs may be provided in a lattice shape so that the reinforcing ribs intersect each other”. In this case, the strength and rigidity of the reinforcing rib, and hence the lid member, are further increased, and the durability of the peripheral portion of the inclined wall portion is improved by providing a reinforcing rib that connects the inclined wall portion and the reinforcing rib. Such effects are more reliably exhibited. Further, the technical idea described in the means 1 may be embodied in a “packing unit in which an article placed on a pallet is covered with a lid member”. Further, the pallet includes a plurality of column portions and an upper deck portion that connects between the upper end portions of the plurality of column portions, and opens downward between the plurality of column portions, and forklifts from the side It is good also as being provided with the fork insertion part which can insert a fork.

  Mean 2. Means 1 is characterized in that a groove portion for positioning a binding band to be mounted between the lower surface side of the pallet of the packing unit and the upper surface side of the lid member is provided on the outer surface of the inclined wall portion. The lid member.

  According to the means 2, the situation that the binding band attached to the packing unit is shifted can be suppressed. In particular, by providing a groove in a portion where the boundary between the top wall and the outer wall is an inclined wall, for example, the boundary between the top wall and the outer wall is connected at a substantially right angle. Compared with the case where the binding band is hung, the deformation of the boundary portion is suppressed (as described above, the reinforcing rib is additionally provided on the inner surface side of the inclined wall portion, so that the effect becomes more remarkable. In addition, the groove portion can be provided with a wider area at a suitable position.

  Further, for example, the binding band may be positioned by providing a pair of ribs on the inclined wall portion. In this case, however, the ribs are damaged when the fork of the forklift comes into contact with the ribs. (Folding), there is a concern that positioning may become impossible. In this regard, by positioning the binding band by providing the groove portion on the inclined wall portion, for example, even if the fork of the forklift contacts the groove portion, there is a possibility that the groove portion may be damaged to the extent that the binding band cannot be positioned. Low. Accordingly, it is possible to stabilize the attachment state of the binding band.

  Means 3. The lid member according to claim 2, wherein the groove portion is provided continuously from the inclined wall portion to the top wall portion and the outer wall portion.

  According to the means 3, the attachment state of the binding band can be further stabilized, and the positioning effect of the binding band can be further enhanced.

The binding band 31 attached to the groove portion 32 of the lid member 4 of the packaging unit 1 and the pallet side groove portion 17 of the pallet 2 extends in the vertical direction.

  As described above in detail, according to the present embodiment, when the packing units 1 are stacked in the lid member 4, the portion disposed below the fork insertion portion 14 of the pallet 2 of the upper packing unit 1. , The boundary portion between the top wall portion 21 and the outer wall portion 22 is configured by an inclined wall portion 28 that obliquely connects the top wall portion 21 and the outer wall portion 22. Further, the lid member 4 includes a reinforcing rib 30 that connects the inner side surface of the inclined wall portion 28 and the reinforcing rib 23. For this reason, when the upper packaging unit 1 among the stacked packaging units 1 is sequentially transported by a forklift or the like, when the fork of the forklift is inserted into the fork insertion portion 14 of the pallet 2, the tip of the fork is a lid member. When the four inclined wall portions 28 are contacted, all of the ribs (the reinforcing ribs 23 and the reinforcing ribs 30) connected to the inner surface of the inclined wall portion 28 (and the top wall portion 21) are In cooperation, the inclined wall portion 28 is supported. That is, the impact of the fork coming into contact with the lid member 4 can be distributed to all the ribs (and the top wall portion 21) connected to the inclined wall portion 28 via the inclined wall portion 28. Can be prevented from being damaged or deformed. Therefore, the durability of the lid member 4 can be improved. In particular, regarding the section X in which the inclined wall portion 28 is provided in the circumferential direction of the lid member 4 in the outer wall portion 22, not only the reinforcing rib 23 but also the reinforcing rib 30 is connected. Therefore, the rib pitch for supporting the inclined wall portion 28 in contact with the fork as described above is reduced while suppressing the weight of the lid member 4 as compared with the case where the ribs provided on the lid member 4 are increased as a whole. The effect of preventing the deformation of the contact portion and the like can be further enhanced.

  Further, the fork of the forklift contacting the inclined wall portion 28 is guided to the fork insertion portion 14 side by the inclination of the inclined wall portion 28 (the fork can be released to the fork insertion portion 14 side). Therefore, the effect of preventing the contact portion with the fork from being damaged is more prominent. In addition, the strength of the outer peripheral portion of the lid member 4 can be effectively increased by the reinforcing rib 30, and the shape can be stabilized. The reinforcing ribs 23 are provided in a lattice shape so that the reinforcing ribs 23 intersect each other. For this reason, the strength and rigidity of the reinforcing rib 23 and thus the lid member 4 are further increased, and the reinforcing rib 30 that connects the inclined wall portion 28 and the reinforcing rib 23 is provided to provide a peripheral portion of the inclined wall portion 28. The effect of improving the durability of is more reliably achieved.

  A groove 32 for positioning the binding band 31 is provided on the outer surface of the inclined wall portion 28. For this reason, the situation where the binding band 31 with which the packaging unit 1 was mounted | worn can shift | deviate. In particular, the groove portion 32 is provided in a portion where the boundary between the top wall portion 21 and the outer wall portion 22 is the inclined wall portion 28, so that, for example, the top wall portion 21 and the outer wall portion 22 are substantially perpendicular to each other. Compared to the case where the binding band 31 is hung on the connected boundary portion, deformation or the like of the boundary portion is suppressed (as described above, the reinforcing rib 30 is additionally provided on the inner surface side of the inclined wall portion 28. Therefore, such an effect becomes more conspicuous), and the groove 32 can be provided with a wider area at a suitable position.

  Further, for example, it is conceivable to position the binding band 31 by providing a pair of ribs projecting from the both side positions of the binding band 31 in the inclined wall portion 28. There is a concern that when the fork comes into contact, the rib is damaged (broken), making positioning impossible. In this respect, by positioning the binding band 31 by providing the groove portion 32 in the inclined wall portion 28, for example, even if the fork of the forklift contacts the groove portion 32, the groove portion 32 cannot position the binding band 31. Is unlikely to be damaged. Therefore, stabilization of the mounting state of the binding band 31 can be achieved.

  In addition, the groove portion 32 is provided continuously from the inclined wall portion 28 to the top wall portion 21 and the outer wall portion 22. For this reason, the mounting state of the binding band 31 can be further stabilized, and the positioning effect of the binding band 31 can be further enhanced.

And may extend. In addition, the extending directions of the plurality of reinforcing ribs 30 connected to the same inclined wall portion 28 may not be aligned in the same direction, and extend so as to be away from each other or approach each other. Also good.

  (D) In the above embodiment, the groove portion 32 provided in the inclined wall portion 28 of the lid member 4 is also provided continuously in the outer wall portion 22 and the top wall portion 21, but the outer wall portion 22 and The groove portion 32 may not be provided in either one of the top wall portions 21, or the groove portion 32 may be provided only in the inclined wall portion 28 as shown in FIG. 9. In addition, in the above-described embodiment, the depth of the groove portion 32 may be configured to be the same as the thickness of the binding band 31 or deeper than the thickness of the binding band 31. In this case, positioning of the binding band 31 installed in the groove portion 32 is more reliably performed, and the situation where the fork of the forklift comes into contact with both side portions of the binding band 31 accommodated in the groove portion 32 can be suppressed. And damage to the binding band 31 can be suppressed.

  Further, as shown in FIG. 10, on the outer surface side of the lid member 4 (the inclined wall portion 28, the top wall portion 21, and the outer wall portion 22), it is slightly (for example, about 1 mm) from a portion adjacent to both side portions of the groove portion 32. It is good also as providing the auxiliary | assistant protrusion 41 which protrudes. In this case, positioning of the binding band 31 installed in the groove 32 is more reliably performed without increasing the depth of the groove 32 as in the case of increasing the depth of the groove 32 as described above. The effect of is produced. Furthermore, by making the protrusion length of the auxiliary protrusion 41 as small as possible, even if the fork of the forklift contacts the auxiliary protrusion 41, damage to the auxiliary protrusion 41 can be suppressed.

  Further, although not particularly mentioned in the above embodiment, the reinforcing ribs 23 and the reinforcing ribs 30 may be connected to the inner surface of the groove portion 32. In this case, deformation of the groove 32 can be effectively prevented. In addition, in the said embodiment, although the groove part 32 is comprised by denting the applicable location of the cover member 4 inward of the cover member 4, the inclined wall part 28 is thicker than the top wall part 21, for example. While configuring, it is good also as comprising a groove part by making the applicable location of the inclination wall part 28 thin.

  (E) In the above embodiment, the pallet 2 and the lid member 4 are made of polypropylene, but may be made of other resin materials such as polyethylene, PET, and polyamide. Further, the pallet 2 of the above embodiment is embodied as a two-way insertion type pallet 2 in which a fork of a forklift can be inserted from two side surfaces out of four side surfaces constituting the outer peripheral surface of the pallet 2. It is also possible to adapt to a four-way type pallet.
