Description

[Technical Field]

[0001] The present invention relates to a receiving member for a transport container (hereinafter simply referred to as a receiving member) that is installed on a transport container for the purpose of fixing items such as products and parts stored in the transport container, and in particular to a receiving member that includes a receiving tool having a receiving portion that supports the items, a holder that holds this receiving tool, and an attachment that is used when attaching this holder to the transport container. [Background technology]

[0002] Containers used for transporting and transporting products (hereinafter referred to as transport containers) often have support members installed to prevent products, parts, and other items from being scratched or broken. For example, a known support member has a support portion with a three-dimensional curved surface formed by vacuum forming to conform to the shape of the item so that the item can be securely fixed to the transport container. However, conventionally, such support members have been fixed to the transport container using bolts and nuts, which poses a problem of time-consuming installation and removal from the transport container.

[0003] To address these issues, for example, Patent Document 1 discloses an invention entitled "Method for manufacturing a support member for a transport container and a preform used therefor," which relates to a method for manufacturing a support member and a preform used therefor, which is less likely to reduce the strength of the part that supports the product or part and can be easily attached to the plate material that makes up the transport container. Explaining using the symbols shown in the drawings of Patent Document 1, the preform 1 disclosed in Patent Document 1 is made of a plate material formed by injection molding of a thermoplastic resin and having an approximately rectangular shape in a plan view, and is structured to include a molding target portion 2 in which a storage item receiving portion 15a is formed by vacuum molding, a boundary portion 3 that surrounds the molding target portion 2 and is arranged to protrude from the second surface 1b, a first connecting portion 4 and a second connecting portion 10 that are arranged outside the boundary portion 3 and have side surfaces 1c and 1d corresponding to the two parallel sides that make up the above-mentioned rectangle, a protruding portion 5 that has a flat surface parallel to the first surface 1a and is arranged on the first surface 1a of the first connecting portion 4, and an engaging claw 12 that is arranged symmetrically with a rectangular opening 9 provided on the flat surface, with respect to the second connecting portion 10, across the molding target portion 2. The engaging claw 12 comprises a flat portion 13 extending from the seat plate 10a of the second connecting portion 10 and bent at a right angle toward the first surface 1a, and an engaging portion 14 extending from the flat portion 13 so as to protrude in a direction away from the molded part 2 when the seat plate 10a is viewed in a plane and bent at an acute angle toward the second surface 1b, and is characterized in that the flat portion 13 and the engaging portion 14 become sized to be placed within the opening 9 by elastically deforming them so that the angle between them becomes small, and the elastic deformation recovers so that the angle becomes large, allowing the engaging claw 12 to engage with the opening 9.

[0004] When the plate material used for the transport container has through holes in which the protrusions 5 and engaging claws 12 can be placed, preform 1 having the above structure and a receiving member manufactured using this preform 1 are arranged with their first surfaces 1a facing each other and the plate material sandwiched between them, and when one of the engaging claws 12 is engaged with the opening 9 of one of the protrusions 5 through the through hole of the plate material, the receiving member and preform 1 are fixed to both sides of the plate material. In other words, preform 1 having the above structure has the effect of being easily attached to the plate material used for the transport container by combining it with a receiving member manufactured from it.

[0005] In addition, Patent Document 2 discloses an invention titled "Manufacturing method of receiving member for transport container and mold used therefor" that relates to a method for inexpensively manufacturing a receiving member that can be detachably attached to a component that makes up a transport container. Using the symbols shown in the drawings of Patent Document 2, the receiving member 1 disclosed in Patent Document 2 has a storage item receiving portion 1a formed on a part of a flat plate material made of thermoplastic resin, and has multiple rod-shaped protrusions 1c formed so that the storage item receiving portion 1a protrudes in one direction. In a receiving member 1 with this structure, unlike conventional technology in which the storage item receiving portion 1a supports the item over its entire surface, the area of ​​contact between the item and the storage item receiving portion 1a is small, making it less likely for the stored item to be damaged. Also, since there are fewer restrictions on the shape of the portion of the storage item receiving portion 1a that does not contact the item, it is possible to set the processing precision of this portion lower than that of other portions, and this reduces the manufacturing cost of the vacuum forming mold used to form the storage item receiving portion 1a. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent No. 7309249 [Patent Document 2] Patent No. 7333682 Summary of the Invention [Problem to be solved by the invention]

[0007] The preform described in Patent Document 1 and the receiving member described in Patent Document 2 must be capable of injection molding and vacuum forming, so the materials that can be used are limited. For example, even if the part (receiving portion) that supports the article stored in the transport container is made of a flexible material such as rubber, such a material is not suitable for vacuum forming and cannot be used for the above-mentioned preform or receiving member. In other words, the inventions disclosed in Patent Documents 1 and 2 have the problem that it is not easy to impart properties different from those of the preform to the receiving portion.

[0008] The present invention was made to address such conventional circumstances, and is characterized by providing a support member for a transport container in which the material of the part that supports the item is different from the material of the part used for attachment to the transport container. [Means for solving the problem]

[0009] In order to achieve the above-mentioned object, the first invention is a receiving member for a transport container that is installed on a transport container for the purpose of fixing stored items, and is characterized in that it comprises a receiving device made of a plate material provided with a receiving portion that supports the items, a holder that holds the receiving device, and an attachment device used when attaching the holder to the transport container, and the holder and attachment device that are detachably attached to the transport container are molded from a material that can be used for both injection molding and vacuum forming, the holder has a hooking means that can be hooked onto a hooking portion provided on the receiving device, and the material of the receiving device is not limited to one that can be used for injection molding or vacuum forming.

[0010] In the first invention, the material of the receiving tool is not limited to those that can be injection molded or vacuum formed, which has the effect of imparting properties to the receiving portion that the holder does not have. For example, low-toughness (brittle) materials such as CFRP, HDPE, and conductive compound materials, and flexible materials such as elastomers cannot be used for preforms even if they can be injection molded, because the hooking and engaging means provided on the preform do not function properly. Furthermore, nylon and CFRP are not suitable for vacuum forming. Therefore, these materials are difficult to use for the holder, but can be used for the receiving tool. Furthermore, when elastomer, nylon, CFRP, and HDPE are used for the receiving tool, the receiving portion will have flexibility, wear resistance, conductivity, and oil resistance, respectively. In addition, in the first invention, when the hooking means of the holder is hooked to the hooking portion of the receiving device, the receiving device is held by the holder, and when the hooking state of the hooking means to the hooking portion is released, the receiving device can be removed from the holder. Furthermore, since the holder and the attachment tool are detachable from the transport container, the first invention has the effect of easily attaching them to and detaching them from the plate material used in the transport container.

[0011] A second invention is characterized in that, in the first invention, the holder is provided with a first fitting portion that can be fitted into the receiving portion of the receiving tool. In the second invention of the above structure, in addition to the effect of the first invention, the receiver is positioned relative to the holder by the first fitting portion fitting into the receiving portion.

[0012] A third invention is characterized in that, in the second invention, the mounting fixture is provided with a second fitting portion that can be fitted into the first fitting portion of the holder. In the third invention of the above structure, in addition to the effect of the second invention, the second fitting portion fits into the first fitting portion, thereby providing the effect that the mounting tool is positioned relative to the holder.

[0013] A fourth invention is characterized in that in the second invention, the first fitting portion of the holder has a rod-shaped projection formed so as to project in one direction. In the fourth invention of the above structure, in addition to the effect of the second invention, the rod-shaped protrusion of the first fitting portion has the effect of being easily formed by vacuum molding using a mold consisting of a plurality of pins made of a cylindrical or cylindrical body and a block on whose upper surface the pins are erected.

[0014] A fifth invention is characterized in that in any one of the first to fourth inventions, the holder is made of polypropylene. In the fifth invention, since polypropylene has the property (hinge property) of not being broken even when repeatedly bent, when a locking claw is provided on the holder as a locking means and a locking hole through which this locking claw can be inserted is provided on the receiving device as a locking portion, in addition to the effect of any of the first to fourth inventions, the locking claw is less likely to be damaged even when the locking claw is bent to lock into the locking hole, or when the bent locking claw is straightened out and returned to its original shape to release the locking state in the locking hole. [Effects of the Invention]

[0015] According to the first invention, by giving the receiving part characteristics suitable for the items stored in the transport container, it is possible to appropriately secure the items within the transport container. In addition, since the receiving device can be easily detached from the holding device, it is easy to separate the items during recycling even if they are made of different materials. Furthermore, according to the first invention, since the holding device and mounting fixture can be easily attached and detached to the plate material that makes up the transport container, the work of installing the items within the transport container can be performed efficiently.

[0016] In the second invention, the receiver is positioned relative to the holder by engaging the first fitting portion with the receiving portion, making it easier to align the latching means of the holder with the latching portion of the receiver. Therefore, in addition to the effects of the first invention, the second invention has the effect of allowing the holder to be attached to the receiver efficiently in a short time. Furthermore, even if the rigidity of the receiving portion is low, the strength of the receiving portion can be increased by engaging the first fitting portion provided on the holder, which has higher rigidity than the receiver, with the receiving portion.

[0017] In the third invention, the mounting fixture is positioned relative to the holder by engaging the second engaging portion with the first engaging portion, which in addition to the effect of the second invention has the effect of allowing the mounting fixture to be attached to the holder efficiently in a short time.

[0018] According to the fourth invention, the first fitting portion of the holder can be easily formed using a vacuum forming mold with a simple structure, which has the effect of reducing the cost required to form the first fitting portion in the holder in addition to the effect of the second invention.

[0019] According to the fifth invention, when a locking claw is provided on the holder as a hooking means and a locking hole through which the locking claw can be inserted is provided on the receiving device as a hooking portion, the locking claw is less likely to be damaged even if it is bent or straightened, and therefore, in addition to the effects of any of the first to fourth inventions, the effect of being able to reduce manufacturing costs by commonly attaching multiple receiving devices with different receiving portion shapes and materials to the same holder is achieved.

DETAILED DESCRIPTION OF THE INVENTION

[0021] The structure of the receiving member for a transfer container according to the present invention and the operation and effects of the invention will be specifically described with reference to FIGS. In the following description, an example is given in which the receiving member is installed on the bottom plate of the transport container, but the receiving member need not be entirely flat; it may be a member having at least a plate-like portion in which an opening can be provided, or it may be installed on a plate-like member other than the bottom plate. Even when the receiving member is installed on such a member, the functions and effects of the present invention described below are similarly exhibited. In this specification, the surface of the transport container facing the plate material and the surface opposite thereto are referred to as the "first surface" and the "second surface," respectively. [Example]

[0022] Fig. 1(a) is an external perspective view of a receiving member 1a according to a first embodiment of the present invention, and Fig. 1(b) is an external perspective view of a mounting fixture 4 which constitutes the receiving member 1a together with the receiving fixture 2 and holder 3 shown in Fig. 1(a). Also, Fig. 2(a) is an enlarged perspective view of the first connecting portion 6 and the second connecting portion 13 in Figs. 1(a) and 1(b), Fig. 2(b) is an enlarged perspective view of the engaging claw 15, and Fig. 2(c) is a perspective view showing the state in which the engaging claw 15 is engaged with the opening 12 of the protruding portion 8. Furthermore, Fig. 3 is an external perspective view of the holder 3 shown in Fig. 1(a).

[0023] As shown in Figures 1(a) and 1(b), the receiving member 1a includes a receiving device 2 having a receiving portion 23 for supporting items such as products and parts stored in a transport container, a holder 3 for holding the receiving device 2, and an attachment device 4 used to attach the holder 3 to the transport container. 1(a) and 1(b) and 2(a) and 3, the holder 3 and the fixture 4 are made of a plate material formed by injection molding of a thermoplastic resin such as polypropylene, polyester, polyolefin, polyamide, or polycarbonate and having a generally rectangular shape in plan view, and are equipped with a molding target portion 5 to be vacuum formed, and a first connecting portion 6 and a second connecting portion 13 provided on the outside of this molding target portion 5 and having side surfaces 3c and 3d or side surfaces 4c and 4d corresponding to two parallel sides constituting the rectangle. A pair of recesses 7, 7 having a rectangular shape in plan view are provided symmetrically on the first surface 4a of the fixture 4 so as to sandwich the molding target portion 5 therebetween. In addition, the molding target portion 5 of the holder 3 is provided with a first fitting portion 20 (see Figure 3) with a stepped structure that can fit with the receiving portion 23 of the receiving device 2, and the molding target portion 5 of the mounting device 4 is provided with a second fitting portion 25 that can fit with the first fitting portion 20 of the holder 3. The recess 7 is provided for the purpose of reducing deformation due to shrinkage during injection molding, and may be omitted depending on the thickness of the part and the conditions of injection molding.

[0024] The first connecting portion 6 consists of a seat plate 6a having a rectangular shape in a plan view, and a protrusion portion 8 and protrusion portions 9, 10 provided on the first surface 3a or the first surface 4a of this seat plate 6a, and the seat plate 6a has circular through holes 11a, 11b provided near the side surfaces 3e, 3f or the side surfaces 4e, 4f that are perpendicular to the side surfaces 3c, 3d or the side surfaces 4c, 4d, respectively. The protruding portion 8 is composed of a pair of side plates 8a, 8a that are perpendicular to the seat plate 6a and parallel to the side surfaces 3c, 4c, a flat top plate 8c that connects the upper ends of the pair of side plates 8a, 8a and is parallel to the first surfaces 3a, 4a, a pair of side plates 8b, 8b that are perpendicular to the seat plate 6a and connect the top plate 8c to the pair of side plates 8a, 8a, and four reinforcing plates 8d (see FIG. 1(a)) that are placed parallel to the side plate 8b and connect the pair of side plates 8a, 8a, and a pair of openings 12, 12 are provided in places of the protruding portion 8 where the reinforcing plates 8d are not provided. Note that the opening 12 is formed by cutting out a part of the inner wall surface that corresponds to one of the long sides of the rectangle in a plan view, so that a pair of locking portions 12a, 12a are formed on the side farther from the molding target part 5. Furthermore, the upper surface plate 8c of the protruding portion 8 is provided with protrusions 9 (see FIG. 1(b)) at both ends in the longitudinal direction, and with a protrusion 10 at approximately the center.

[0025] Circular through-holes 11b are provided in the seat plate 13a of the second connecting portion 13 near the side surfaces 3e, 3f or the side surfaces 4e, 4f. A pair of locking pieces 14b, 14b, which protrude in a direction perpendicular to the side surfaces 3d, 4d, are rectangular in plan view, and are divided into two by a slit 14a, are provided in approximately the center of the seat plate 13a in the width direction (the direction perpendicular to the side surfaces 3e, 3f or the side surfaces 4e, 4f). In addition, a pair of slits 13b, 13b, each having a predetermined length in the direction perpendicular to the side surfaces 3d, 4d, are provided in the seat plate 13a of the second connecting portion 13 between the pair of through-holes 11b, 11b, with a pair of engaging claws 15, 15 sandwiched therebetween. As will be described later, when the holder 3 and the mounting fixture 4 are joined, the protrusion 9 of the mounting fixture 4 abuts against the side surface 3d of the holder 3, and the protrusion 9 of the holder 3 abuts against the side surface 4d of the mounting fixture 4. In other words, the holder 3 and the mounting fixture 4 are structured such that their movements in the direction perpendicular to the side surface 3d or the side surface 4d are restricted by the protrusion 9 abutting against the side surface 3d or the side surface 4d, respectively.

[0026] As shown in FIG. 2(a), the protrusion 10 comprises a straight portion 10a parallel to the longitudinal direction of the top plate 8c of the protruding portion 8, and a pair of protruding portions 10b, 10b and 10c provided at both ends and approximately in the center of the straight portion 10a so as to be perpendicular to the longitudinal direction of the top plate 8c. As described above, when the holder 3 and the mounting fixture 4 are joined, the protruding portion 10c of one of the two is disposed inside the slit 14a, and the locking piece 14b of one of the two is disposed between the protruding portions 10b and 10c of the other. In other words, the holder 3 and the mounting fixture 4 are structured so that the movement of one of the two in directions parallel to and perpendicular to the side surface 3d or 4d is restricted by the positioning of the locking piece 14b of one of the two between the protruding portions 10b and 10c of the other of the two protrusions 10.

[0027] As shown in FIG. 2(a), the engaging claw 15 includes a seat plate 13a having slits 13b on both sides thereof, a flat portion 16 extending from the seat plate 13a and bent at a substantially right angle toward the first surfaces 3a and 4a (see FIG. 1(a) or 1(b)) as shown in FIG. 2(b), and an engaging portion 17 extending from the flat portion 16 so as to protrude away from the molding target part 5 when the seat plate 13a is viewed from above and bent at an acute angle toward the second surfaces 3b and 4b (see FIG. 2(a)). A portion of the tip of the engaging portion 17 is cut out in a substantially rectangular shape in plan view, thereby forming a wide portion 17a extending from the flat portion 16 and a narrow portion 17b continuing from the wide portion 17a. A pair of engaging end surfaces 17c, 17c are formed on both sides of the narrow portion 17b. In addition, the second surfaces 3b, 4b (see Figure 2(a)) of the seat plate 13a, to which the flat portion 16 of the engaging claw 15 extends, have thick portions 15a on both sides in the width direction (direction parallel to the side surfaces 3d, 4d). The holder 3 and the mounting fixture 4 become inseparable from each other by engaging the engagement claw 15 of one with the opening 12 of the protrusion 8 of the other, and at this time, the narrow portion 17b of the engagement portion 17 is positioned between a pair of locking portions 12a, 12a as shown in Figure 2(c).

[0028] 3, the holder 3 has a third connecting portion 18 having side surfaces 3e and 3f, which is provided on the outside of the molding target portion 5, and a seat plate 18a of the third connecting portion 18 has four notches 18b of a predetermined depth formed perpendicular to the side surfaces 3e and 3f, and rod-shaped bodies 19 parallel to the side surfaces 3e and 3f are installed near the side surfaces 3e and 3f so as to straddle the notches 18b with respect to the second surface 3b. Locking claws 21 are formed inside the notches 18b, extending from inner wall surfaces 18c (see FIG. 4(a)) of the notches 18b parallel to the side surfaces 3e and 3f and bending toward the second surface 3b.

[0029] 4(a) is an enlarged view of the locking claw 21 and its surroundings in FIG. 3, and FIG. 4(b) is a view showing the locking claw 21 in FIG. 4(a) in a bent state. As shown in Figure 4(a), the locking claw 21 has a flat portion 21a extending from the inner wall surface 18c of the cutout 18b so as to be bent at approximately a right angle toward the second surface 3b, a connecting portion 21b that protrudes in a direction away from the molded part 5 when the seat plate 18a is viewed in a plane and is bent so as to form an obtuse angle with the flat portion 21a, and a locking portion 21c extending from the connecting portion 21b and bent at an acute angle toward the second surface 3b. In addition, thick portions 22a are provided on the flat portion 21a on the side closer to the seat plate 18a and on the side closer to the connecting portion 21b, and a thin portion 22b is provided between the two thick portions 22a and parallel to the second surface 3b. That is, the locking claw 21 can be easily bent at the thin portion 22b of the flat portion 21a in a direction in which the locking portion 21c approaches the second surface 3b, and when the thick portion 22a closer to the connection portion 21b is bent at approximately a right angle to the thick portion 22a closer to the seat plate 18a, the locking portion 21c is structured to lock onto the rod-shaped body 19 as shown in Figure 4(b).

[0030] Fig. 5(a) is an external perspective view of the receiving device 2 shown in Fig. 1(a), and Fig. 5(b) is an external perspective view showing the receiving device 2 shown in Fig. 5(a) held by the holder 3 shown in Fig. 3. Also, Fig. 6(a) is a cross-sectional view taken along line AA in Fig. 5(b), and Fig. 6(b) is a side view showing the state in which the mounting device 4 shown in Fig. 1(c) is attached to the holder 3 in Fig. 1(a). As shown in Figure 5(a), the receiver 2 is made of a plate material made of thermoplastic elastomer and has a rectangular shape when viewed from above. The receiver 2 has a stepped receiver portion 23 that can fit into the first fitting portion 20 (see Figure 6(a)) of the holder 3 and is provided perpendicular to the first surface 2a and protruding toward the second surface 2b. Four circular locking holes 24 are provided along each of the side surfaces 2c and 2d that correspond to the two parallel sides that make up the rectangle. Furthermore, as shown in Figures 5(b) and 6(a), in the receiving device 2, eight locking holes 24 are formed at locations that can be simultaneously inserted through the eight locking claws 21 of the holder 3 when the first fitting portion 20 of the holder 3 is fitted into the receiving portion 23. That is, first fitting portion 20 has the function of positioning receiver 2 relative to holder 3 by fitting with receiving portion 23. Therefore, with receiving member 1a, it is easy to align locking claw 21 of holder 3 with locking hole 24 of receiver 2. Therefore, with receiving member 1a, the work of attaching holder 3 to receiver 2 can be performed efficiently in a short time. Furthermore, even if the rigidity of receiving portion 23 is low, the strength of receiving portion 23 can be increased by fitting first fitting portion 20 provided on holder 3, which has higher rigidity than receiver 2, into receiving portion 23.

[0031] In Figure 5(b), when the thick portion 22a of the locking claw 21 near the connection portion 21b is bent at approximately a right angle to the thick portion 22a near the seat plate 18a, the locking claw 21 cannot be removed from the locking hole 24 of the receiving device 2, and the receiving device 2 is held by the retaining device 3 as shown in Figure 1(a). In Figure 1(a), the first surface 4a of the mounting fixture 4 is faced to the first surface 3a of the holder 3, and the second fitting portion 25 of the mounting fixture 4 is fitted into the first fitting portion 20 of the holder 3, and the engaging claw 15 of the holder 3 is brought close to the opening 12 of the protruding portion 8 of the mounting fixture 4, and the engaging claw 15 of the mounting fixture 4 is brought close to the opening 12 of the protruding portion 8 of the holder 3. In this way, when the second fitting portion 25 is fitted into the first fitting portion 20, the mounting tool 4 is positioned relative to the holder 3, which makes it easy to align the engagement claw 15 on one side with the opening 12 of the protrusion 8 on the other side. Therefore, with the receiving member 1a, the mounting tool 4 can be attached to the holder 3 efficiently in a short time.

[0032] From this state, when the mounting tool 4 is brought closer to the holder 3, the engaging claw 15 elastically deforms so that the angle between the flat portion 16 and the engaging portion 17 decreases, allowing the flat portion 16 and the wide portion 17a of the engaging portion 17 to pass through the opening 12. Then, when the wide portion 17a of the engaging portion 17 passes through the opening 12, the elastic deformation of the engaging claw 15 is restored, and the narrow portion 17b of the engaging portion 17 is positioned between the pair of locking portions 12a, 12a, and the pair of locking end surfaces 17c, 17c formed on both sides of the narrow portion 17b are locked with the pair of locking portions 12a, 12a, respectively. As a result, the mounting tool 4 is fixed to the holder 3 as shown in FIG. 6(b). That is, the holder 3 and the mounting fixture 4 are inseparable from each other by the engagement claw 15 of one engaging with the opening 12 of the protruding portion 8 of the other. 6(b), when the tip of narrow portion 17b of engaging portion 17 is held with the fingers, and engaging claw 15 is elastically deformed in a direction that reduces the angle between flat portion 21a and engaging portion 17 until flat portion 21a and wide portion 17a of engaging portion 17 can pass through opening 12, the engagement between engaging claw 15 and opening 12 of protruding portion 8 is released. When engaging claw 15 is then removed from opening 12 of protruding portion 8, holder 3 and mounting fixture 4 become separable.

[0033] 7(a) is a plan view of the bottom plate 26 of the transport container, and FIG. 7(b) is a side view of the bottom plate 26 with the receiving member 1a attached thereto. The transport container includes a frame made of, for example, a plurality of square pipes or the like combined to form the sides of a rectangular parallelepiped, and a plate material (hereinafter referred to as bottom plate 26) that is rectangular in plan view and is installed at the bottom opening of the frame. As shown in Fig. 7(a), bottom plate 26 is rectangular in plan view and has a pair of through holes 26a, 26a and an opening 26b that are rectangular in plan view. When bottom plate 26 is arranged parallel to first surface 3a of holder 3 (see Fig. 3) or first surface 4a of mounting fixture 4 (see Fig. 1(b)), protrusion 8 and engagement claw 15 (see Fig. 2(a)) can be simultaneously placed inside the pair of through holes 26a, 26a, and opening 26b can accommodate first fitting portion 20 of holder 3 and first fitting claw 15 of mounting fixture 4. In the case where the second fitting portion 25 of the holder 3 and the mounting fixture 4 can be arranged inside, the holder 3 and the mounting fixture 4 are fixed to the bottom plate 26 by arranging the first fitting portion 20 of the holder 3 and the second fitting portion 25 of the mounting fixture 4 inside the opening 26b with the first surfaces 3a and 4a facing each other against the bottom plate 26 of the transport container as shown in Figure 7(b), and engaging the engaging claw 15 (see Figure 2(a)) of one of the protrusions 8 with the opening 12 (see Figure 2(a)) of the other protrusion 8 through the through hole 26a. Furthermore, as already explained, when engaging claw 15 is elastically deformed in a direction that reduces the angle between flat surface portion 21a and engaging portion 17, for example by holding the tip of narrow portion 17b of engaging portion 17 with the fingers, the engagement between engaging claw 15 and opening 12 of protruding portion 8 is released, and holder 3 and mounting fixture 4 can be separated from each other. In other words, holder 3 and mounting fixture 4 can also be easily removed from bottom plate 26. In this way, the holder 3 and the fixture 4 are detachably attached to the bottom plate 26 of the transport container.

[0034] In the receiving member 1a having the above structure, the method for forming the receiving fixture 2 is not limited to injection molding or vacuum forming, so the receiving fixture 2 does not need to be made of the same material as the holder 3 or the mounting fixture 4. For example, flexible elastomers are not suitable as preform materials for mounting or holding functions and therefore cannot be used for the holder 3 or the mounting fixture 4, but they can be used for the receiving fixture 2. If the receiving fixture 2 is made of an elastomer, the receiving portion 23 will be flexible. Similarly, nylon, CFRP, or HDPE, which are difficult to use for the holder 3 or the mounting fixture 4, can also be used for the receiving fixture 2. If the receiving fixture 2 is molded from these materials, the receiving portion 23 will have wear resistance, conductivity, and oil resistance, respectively. Thus, in the receiving member 1a, the material for the receiving fixture 2 is not limited to one that can be injection molded or vacuum formed, so the receiving fixture 2 can be made of a different material from the holder 3 or the mounting fixture 4. This provides the receiving portion 23 with properties that the holder 3 or the mounting fixture 4 does not have. Therefore, in the receiving member 1a, by imparting characteristics to the receiving portion 23 that are suitable for the article stored in the transport container, the article can be properly fixed inside the transport container.

[0035] In addition, in the receiving member 1a, when the locking claws 21 of the holder 3 inserted into the locking holes 24 of the receiver 2 are bent to engage the locking claws 21 with the locking holes 24, the receiver 2 is held by the holder 3. Then, by straightening the bent locking claws 21 back to their original shape, the state in which the locking claws 21 are engaged with the locking holes 24 is released, and the receiver 2 can be removed from the holder 3. In other words, the holder 3 is provided with the locking claws 21 as a locking means that can be engaged with a locking portion consisting of the locking holes 24 provided in the receiver 2. In this way, in the receiving member 1a, the receiving fixture 2 can be easily removed from the holder 3, and therefore separation during recycling is easy even if the two are made of different materials. The latching portion and latching means may have any structure that can detachably fix the receiver 2 to the holder 3, and are not limited to the latching hole 24 and latching claw 21.

[0036] 7(a), if bottom plate 26 used in the transport container has through holes 26a into which protrusions 8 and engaging claws 15 of holder 3 and mounting fixture 4 can be placed, and openings 26b into which first fitting portion 20 of holder 3 and second fitting portion 25 of mounting fixture 4 can be placed, holder 3 and mounting fixture 4 are placed with bottom plate 26 sandwiched therebetween, and then first fitting portion 20 of holder 3 and second fitting portion 25 of mounting fixture 4 are placed inside openings 26b, and one engaging claw 15 is engaged with opening 12 of one protrusion 8 through through hole 26a of bottom plate 26, thereby fixing holder 3 and mounting fixture 4 to both sides of bottom plate 26. In this state, if engaging claw 15 is elastically deformed to release the engagement between engaging claw 15 and opening 12 of protrusion 8, holder 3 and mounting fixture 4 can be separated from each other. That is, the receiving member 1a can be easily attached to the bottom plate 26 used in the transport container and easily removed from the bottom plate 26. Therefore, the receiving member 1a can be efficiently installed in the transport container.

[0037] While thermoplastic resins such as polypropylene, polyester, polyolefin, polyamide, and polycarbonate can be used for the holder 3 and the mounting fixture 4, it is particularly desirable to use polypropylene for the holder 3. Polypropylene has the property of not breaking even when repeatedly bent (hinge properties), so if the holder 3 is made of polypropylene, the locking claws 21 are less likely to break even when they are bent to engage with the locking holes 24, or when the bent locking claws 21 are stretched back to their original shape to release the state of engagement with the locking holes 24. In this case, multiple receivers 2 with different shapes and materials for the receiving portion 23 can be commonly attached to the same holder 3, thereby reducing manufacturing costs. [Example]

[0038] FIG. 8(a) is an external perspective view of a receiving member 1b according to a second embodiment of the present invention, and FIG. 8(b) is an external perspective view of a mounting fixture 29, which constitutes the receiving member 1b together with the receiving fixture 27 and the holder 28 shown in FIG. 8(a). FIG. 9 is an external perspective view of the holder 28. FIGS. 10(a) and 10(b) are a schematic diagram showing the configuration of a thermoforming device 34 used to manufacture the holder 28 and a flowchart for explaining a manufacturing method for the holder 28, respectively. FIG. 11(a) is an external perspective view of the receiving fixture 27, and FIG. 11(b) is a cross-sectional view taken along line BB in FIG. 8(a). Note that in FIG. 9, only one rod-shaped protrusion is designated by a reference numeral to avoid cluttering the drawing. Components already described using FIGS. 1 to 7 are designated by the same reference numerals, and their description will be omitted where appropriate. As shown in Figures 8(a), 8(b) and 9, receiving member 1b is equipped with receiving tool 27, holding tool 28 and mounting tool 29, and receiving tool 27 has receiving portion 30 provided on the molding target portion 5 instead of receiving portion 23 in receiving tool 2 constituting receiving member 1a.

[0039] The holder 28 and the fixture 29 are made of a plate material formed by injection molding of a thermoplastic resin such as polypropylene, polyester, polyolefin, polyamide, or polycarbonate and having a generally rectangular shape in plan view. They are provided on the outside of the molding target 5 to be vacuum-formed, and are equipped with a first connecting portion 6 and a second connecting portion 13, each having side surfaces 28c and 28d or side surfaces 29c and 29d corresponding to two parallel sides of the rectangle. The side surfaces 28c and 28d of the holder 28 and the side surfaces 29c and 29d of the fixture 29 correspond to the side surfaces 3c and 3d of the holder 3 and the side surfaces 4c and 4d of the fixture 4, respectively. A pair of recesses 7, 7 having a rectangular shape in plan view are symmetrically provided on the first surface 29a of the fixture 29, sandwiching the molding target 5 therebetween. The second surface 29b shown in FIG. 8(b) corresponds to the second surface 4b of the fixture 4. Furthermore, the molding target portion 5 of the holder 28 has a plurality of rod-shaped protrusions 31a (see Figure 9) formed to protrude in one direction, and a first fitting portion 31 arranged inside the receiving portion 30 of the receiving device 27 is provided in place of the first fitting portion 20 in the holder 3, and the mounting device 29 differs from the mounting device 4 constituting the receiving member 1a in that the molding target portion 5 does not have a second fitting portion 25.

[0040] 9, the holder 28 has a third connecting portion 18 having side surfaces 28e and 28f, which is provided outside the molding target portion 5, and a seat plate 18a of the third connecting portion 18 has four notches 18b of a predetermined depth formed perpendicular to the side surfaces 28e and 28f, and rod-shaped bodies 19 parallel to the side surfaces 28e and 28f are installed near the side surfaces 28e and 28f so as to straddle the notches 18b with respect to the second surface 28b. Inside the notches 18b, locking claws 21 are formed, extending from inner wall surfaces 18c (see FIG. 4(a)) of the notches 18b parallel to the side surfaces 28e and 28f and bending toward the second surface 28b. In the receiving member 1b, after the receiver 27 is placed on the holder 28 so that all of the locking claws 21 are simultaneously inserted into the eight locking holes 32 (see FIG. 11(a)), when the thick portion 22a of the locking claws 21 closer to the connection portion 21b is bent at a substantially right angle to the thick portion 22a closer to the seat plate 18a, the locking claws 21 cannot be removed from the locking holes 32 of the receiver 27, and the receiver 27 is held by the holder 28 as shown in FIG. 8(a). On the other hand, when the locking claws 21 are stretched from this state to return to their original shape, the locking claws 21 can be removed from the locking holes 32, and the receiver 27 can be easily removed from the holder 28.

[0041] The rod-shaped protrusion 31a of the holder 28 is disposed inside the receiving portion 30 of the receiving device 27, thereby preventing the receiving device 27 from shifting relative to the holder 28 and ensuring the rigidity of the receiving portion 30. Furthermore, in holder 28, the proportion of the area where rod-shaped projections 31a contact the inner surface 30a of receiving portion 30 (see FIG. 11(b)) is smaller than the proportion of the area where receiving portion 23 of receiver 2 contacts the inner surface 20a of first fitting portion 20 of holder 3 (see FIG. 6(a)). Since there are fewer restrictions on the shape of the portion where rod-shaped projections 31a do not contact the inner surface 30a of receiving portion 30, the processing precision of this portion can be set lower than that of other portions. Therefore, holder 28 having the above structure reduces the manufacturing cost of vacuum forming mold 36 (see FIG. 10(a)) used to form rod-shaped projections 31a.

[0042] Here, a method for manufacturing the holder 28 will be described with reference to Figure 10. Figures 10(a) and 10(b) are a schematic diagram showing the configuration of a thermoforming device 34 used to manufacture the holder 28 and a flowchart for explaining the method for manufacturing the holder 28, respectively. In the following description, the state before the molding target portion 5 is vacuum-formed in the holder 28 will be referred to as a preform 33. 10(a), in addition to a heating booth and fasteners (not shown), the thermoforming device 34 is equipped with a plug 35 and a mold 36. The plug 35 is a member for pressing the molded part 5 from above to bring the molded part 5 into close contact with the mold 36, and is placed above the preform 33 which is fixed to the thermoforming device 34 using fasteners so as to be approximately horizontal. On the other hand, the mold 36 is equipped with a plurality of pins 37 which are installed so as to protrude upward, and is placed below the preform 33. The plug 35 may not be used.

[0043] As shown in FIG. 10(b), first, a substantially rectangular preform 33 is formed by injection molding a thermoplastic resin (step S1). Next, the preform 33 is placed in a heating booth (not shown) of a thermoforming device 34, and the molding target part 5 is heated until it reaches a predetermined heat distortion temperature (step S2). After the heated preform 33 is placed in the thermoforming device 34, the mold 36 is pressed from below against the first surface 28a (see FIG. 8(a)) of the molding target part 5 while suctioning air present in the space between the preform 33 and the mold 36, and a plug 35 is pressed from above against the second surface 28b (see FIG. 9) of the molding target part 5 (step S3). Finally, the preform 33 is sufficiently cooled and then removed from the thermoforming device 34 (step S4). According to this method, the holder 28 can be easily manufactured by vacuum forming using the mold 36, which reduces the manufacturing cost of the receiving member 1b and increases the manufacturing efficiency.

[0044] 11(a) and 11(b), receiver 27, which is made of a plate material made of thermoplastic elastomer and has a rectangular shape in a plan view, has receiving portions 30, which are structured so that rod-shaped protrusions 31a of holder 28 can be placed inside, provided so as to protrude perpendicularly from first surface 27a, and has rectangular locking holes 32 provided in four locations along side surfaces 27c and 27d corresponding to two parallel sides constituting the rectangle. Note that these eight locking holes 32 are formed at locations where eight locking claws 21 of holder 28 can be inserted simultaneously when rod-shaped protrusions 31a of holder 28 are placed inside receiving portions 30 of receiver 27, as shown in FIG. Therefore, when the flat portion 21a of the locking claw 21 inserted into the locking hole 32 is bent at approximately a right angle in a direction in which the locking portion 21c approaches the second surface 28b, the locking claw 21 becomes unable to come out of the locking hole 32 of the receiving device 27, and the receiving device 27 is held by the retaining device 28 as shown in Figure 8(a).

[0045] In receiving member 1b having the above structure, as in the case of receiving member 1a, by using a material for receiving fixture 27 that is different from the material for holder 28 and mounting fixture 29, receiving portion 30 is endowed with properties that are not possessed by holder 28 and mounting fixture 29. Therefore, in receiving member 1b as well, by imparting properties to receiving portion 30 that are suitable for an item stored in the transport container, the item can be properly fixed within the transport container. Furthermore, in the case of receiving member 1b, as in the case of receiving member 1a, receiving fixture 27 can be easily removed from holder 28, so that separation during recycling is easy even if the two are made of different materials. Furthermore, the receiving member 1b can also be easily attached to and removed from the bottom plate 26 used in the transport container, so that, as with the receiving member 1a, the installation work inside the transport container can be carried out efficiently.

[0046] Furthermore, if the holder 28 is made of polypropylene, the locking claws 21 are less likely to break, and therefore, by commonly attaching multiple receivers 27 with different shapes and materials for the receiving portion 30 to the same holder 28, manufacturing costs can be reduced. Furthermore, in the holder 28, the rod-shaped protrusion 31a of the first fitting portion 31 can be easily formed by vacuum molding using a mold 36 consisting of a plurality of pins 37 made of a cylindrical or cylindrical body and a block on whose upper surface the pins 37 are erected, thereby reducing the cost required to form the first fitting portion 31 in the holder 28. As with receiving member 1a, the material of receiving element 27 for receiving member 1b is not limited to those that can be injection molded or vacuum formed, and therefore receiving element 27 can be made of a material other than a thermoplastic elastomer. [Industrial Applicability]
