Description

Stacked pallets

The present invention relates to a tray that can contain articles, and particularly relates to a stacked tray that can be used by stacking a plurality of trays on top of each other.

In recent years, the forms of trays for storing various items including food, tools, plants, stationery, documents, etc. have also become diverse. Among such pallets, it is particularly advantageous that the stacked pallet, which can be stacked up and down, can contain many items in a limited space.

However, even if the conventional laminated pallets such as aluminum pallets for food are not used, their overall height in the stacked state is not different from when in use, so the storage performance when not in use is poor. The problem. Therefore, a laminated pallet whose laminated height is changed when in use and when not in use has also been proposed.

For example, the stacked tray disclosed in Non-Patent Document 1 can be stacked up and down in a state of being housed in a cold box for fishing, and its stacked height can be changed when it is in use and when it is not in use. Specifically, when the stacked tray is in use, a storage space can be secured between the upper and lower trays and the fish caught by squid and other fish can be stacked and stored in the cold box, but when not in use, it can be stored in the bottom The trays stacked on the upper side are inserted into the accommodating space of the pallets on the side and accommodated, achieving a lower stack height than when in use.

However, in the stacked tray disclosed in Non-Patent Document 1, only when the upper and lower trays are relatively rotated by 180 degrees and are stacked in a state of opposite left and right (as a result, the upper and lower trays are arranged in a staggered arrangement). A storage space can be secured between the upper and lower trays (in use state). At the same time, the upper and lower trays can be stacked in the same direction by aligning the left and right sides without rotating relative to each other, so that the lower tray can be embedded and stacked on the upper side. The tray is stored (unused (storage) state), so every time you transfer from the used state to the unused state or from the unused state to the used state, you must change the direction of the tray (left and right opposite), processing operability (workability) )difference.

In addition, the laminated tray disclosed in Non-Patent Document 1 is constructed by assembling resin members on the left and right sides of the stainless steel tray body. Therefore, a gap is generated in the assembly part, and foreign matter and the like are easy to enter and accumulate in the gap. Clean up (so it is prone to stuffy smell). Moreover, since stainless steel is used, the overall weight is heavy and expensive.

Moreover, it is not limited to the laminated tray disclosed in Non-Patent Document 1. General metal trays made of stainless steel or aluminum may also need to be handled carefully so as not to produce burrs or edges due to processing conditions. The presence of edges causes injuries, and when such burrs or edges are used in a resin container such as a cold box, the container may be scratched.

In addition, in the conventional laminated trays used for items that should be stored together with ice or water, such as fresh foods or plants, there are also laminated trays equipped with drainage holes for drainage. In most types of trays, the water stacked on the upper tray is discharged into the storage space of the lower tray through the drain hole intact, and the water remains in the tray without being discharged to the outside. Furthermore, in relation to this, in the stacked tray disclosed in the aforementioned Non-Patent Document 1, although water can be drained to the outside through the drain hole, there are cases where the tray stacked on the upper side is caused by the location of the drain hole. When the water is discharged into the storage space of the tray on the lower side, it cannot be said that the drainage to the outside is sufficient.

The present invention is based on the above-mentioned problems, and its purpose is to provide a method that can ensure easy transfer between the use state and the storage state, good handling operability (workability), good drainage to the outside, and difficulty in accumulating foreign matter. A lightweight and inexpensive laminated pallet that is easy to clean and safe.

In order to solve the above-mentioned problems, the present invention is a stacked tray, which is a tray that can store articles, and a stacked tray in which a plurality of the aforementioned trays can be stacked up and down, characterized in that: the aforementioned tray has a main body and a side wall A storage space is defined on the inside with the bottom wall; and state switching parts are respectively provided at both ends of the main body, and can be switched to ensure the use state of the storage space between the trays when the trays are stacked up and down , And in a state where the trays are stacked up and down to fill the storage space, the storage state of the trays can be fitted together, the state switching section has: a plate, which is installed on the main body, can be protruding in the corresponding use state Move between the position and the introduction position corresponding to the storage state; and a support structure that supports the plate at the protruding position of the other tray stacked on the upper side, and the storage space is secured between the tray stacked on the upper side, The plate is supported on the supporting structure of the other tray stacked on the lower side at the protruding position, and the storage space is secured between the other tray stacked on the lower side. In the use state, at the introduction position, it does not interfere with the supporting structure of the other tray stacked on the lower side, so as to cause the body part to be embedded in the storage space of the other tray stacked on the lower side. Storage state.

According to the stacked pallet constructed as described above, since only the plates of the state switching section are moved between the protruding position and the introduction position at both ends of the main body, it is possible to switch between the use state and the storage state with different stacked heights, so there is no need for such The stacked tray disclosed in the aforementioned Non-Patent Document 1 generally changes the direction of the tray every time the state is switched, and the handling operability (workability) is good.

In addition, in the above configuration, it is preferable that the laminated tray is integrally molded by resin. According to this, it is possible to avoid the occurrence of gaps due to the assembly of metal and resin in the laminated tray disclosed in the aforementioned Non-Patent Document 1, and therefore it is possible to avoid the intrusion and accumulation of foreign objects in such gaps. Furthermore, if it is possible to remove parts where dirt is likely to accumulate in this way, cleaning becomes easy, and therefore, it is possible to perform sufficient cleaning to prevent accumulation of foreign matter and the like (thus, it is possible to prevent a stuffy smell). Moreover, since the entire tray is formed of resin, the entire tray is light and inexpensive. Moreover, since there are no sharp burrs or edges of metal, the safety is also good, and the storage body for storing the stacked tray will not be scratched.

Furthermore, in the above configuration, the plate may be slidable or rotatable with respect to the main body part between the protruding position and the introducing position. Accordingly, the user can move the board between the protruding position and the introducing position with one hand. In this case, the positioning of the board to the main body is better at the protruding position and the introduction position, and accordingly, it is possible to prevent accidental switching between the use state and the storage state. Furthermore, it is better to position and fix the support structure in the state where the plate is supported on the support structure of another tray stacked on the lower side at this protruding position. According to this, the protruding position of the plate can be stably maintained, and therefore the use state of the tray can be stably maintained.

It is also possible to install the board on the main body at the protruding position. Moreover, in this configuration, when the trays are fitted into each other by stacking the trays up and down to fill the storage space, the plates can be removed from the main body, or the plates can be introduced after removal. The position is installed on the main body again. In this way, as long as the board can be freely attached to and detached from the main body, the board can be cleaned individually, and the replacement of the board is also easy.

Furthermore, in the above configuration, the state switching unit may be integrally formed with the main body, or may be detachably attached to the main body. If the state switching section is detachably attached to the main body section, the state switching section may be additionally attached to a conventional existing tray without the state switching section to obtain the aforementioned effects of the present invention. Moreover, if the state switching part is detachably attachable to the main body part in this way, if the state switching part as the movable part deteriorates and malfunctions occur, it can be replaced with a new state switching part.

According to this, it is possible to ensure good drainage to the outside. Particularly in this case, it is preferable that the plate has drainage openings that overlap each other so as to communicate with the drainage holes of the supporting structure of another tray stacked on the lower side at the protruding position. According to this, when the trays are stacked up and down to ensure the use state of the storage space, it is possible to use the drainage of the plate. Moreover, in addition, the plate has a water receiving surface facing the drainage space at the protruding position, and the water receiving surface preferably has a guide groove for guiding the received water to the drainage opening. According to this, since the drainage flow path from the plate to the drainage space can be secured and water can be actively guided to the drainage space, efficient and effective drainage can be realized.

Furthermore, in addition to such a drainage structure in the state switching portion, it is preferable that the main body portion has a through hole in the bottom wall that can drain water from the storage space toward the water receiving surface of the plate located at the protruding position. According to this, the water accumulated in the storage space can be guided to the drainage structure of the state switching part through the through hole (the drainage opening of the plate faces the drainage space of the support structure), and further drainage from the storage space to the outside can be ensured Good drainage. Moreover, in this case, it is preferable that the main body has a guide groove on the bottom wall for guiding the water in the containing space to the through hole. According to this, the water in the storage space can be actively guided to the through hole, and the drainage effect can be improved.

Furthermore, in the above configuration, the main body has a spacer rib that abuts the side wall of the other tray so that a part of the side wall protrudes from the storage space of the other tray stacked on the lower side in the storage state. In this way, in the storage state of the tray in which the trays are fitted, a part of the side wall is protruded from the storage space of the other tray stacked on the lower side by the spacer ribs (that is, the upper and lower sides overlap each other in a fitted state). The upper ends of the side walls of the tray are separated from each other up and down), when the tray is switched from the stored state to the used state, grasp the upper end of the side wall of the tray protruding from the stacked body of the tray in the mated state and use them one by one The tray separation operation becomes easy, making it possible to quickly switch from the storage state to the use state.

Furthermore, in the above configuration, it is preferable that the plate has a finger hook hole for catching a finger that moves the plate from the introduction position to the protruding position. According to this, it is possible to easily move the plate from the introduction position to the protruding position with fingers. Moreover, in this case, the finger hook hole can also have a drainage function. Accordingly, the drainage capacity of the tray can be further improved. Furthermore, in relation to the finger hook hole, it is preferable that the drainage space of the support structure also has a hand-reachable space for the finger hook hole of the user who handles the stacked tray. If such an access space is provided, it is easy to hook the fingers in the finger hook holes, and the drainage space also has this access space. The existing space can be effectively used to ensure the access space, and the convenience can be improved without increasing the size of the tray. .

According to the present invention, it is possible to obtain a light weight and low cost that can ensure easy transfer between the used state and the stored state, and has good handling operability (workability), good drainage to the outside, and difficult accumulation of foreign matter, easy cleaning and high safety. Stacked pallets.

In the protruding position shown in the chain line and FIG. 5, the top surface 40a of the supporting structure 40 of the other pallet 1 stacked on the lower side in the stacked state of the pallets is caused The aforementioned use state of the storage space S is ensured between the other trays 1 (see FIG. 5). In the introduction position shown by the solid line in FIG. 1 and in FIG. 4, it is not stacked with the other tray 1 stacked on the lower side. The supporting structure 40 interferes and is introduced to the inside of the tray to cause the aforementioned storage state in which the main body portion 10 is inserted into the storage space S of the other tray 1 stacked on the lower side (see FIG. 4). In addition, the rotating plate 30 is formed of nylon, polypropylene (PP), polyacetal (POM), or the like. Furthermore, as clearly shown in FIG. 3, the rotating plate 30 has a pair of locking portions 50a rotatably locked to the hinge portion 50, and end edges on both sides.

In addition, the state switching unit 20 further has positioning means for positioning the plate 30 with respect to the main body 10 at the protruding position and the introduction position. In this embodiment, this positioning method is realized by the engagement between the protrusion and the opening. Specifically, as shown in FIGS. 1 and 3, the positioning means for positioning the plate 30 to the main body 10 at the protruding position is composed of a pair of protrusions 49, 49 and engagement holes 43, 43. 49, 49 are arranged in such a way that the drainage space F is sandwiched in the back surface 10cb of the bottom wall 10c near the short side wall 10a of the main body 10, and the engaging holes 43, 43 are arranged to be able to interact with the protrusions 49 and 49 are arranged on both sides of the longitudinal direction of the plate 30 in a manner of separation and engagement. The plate 30 is located at the protruding position shown by the one-dot chain line in FIG. 1, and the protrusions 49, 49 and the engaging holes 43, 43 are It is engaged and the plate 30 is positioned at the protruding position. On the other hand, the positioning means for positioning the main body 10 at the introduction position of the plate 30 is composed of a protrusion 47 and a pair of engaging holes 45, 45. The protrusion 47 is arranged away from the protrusions 49, 49 from the longitudinal inner side of the tray. On the back surface 10cb of the bottom wall 10c of the main body 10, the pair of engaging holes 45, 45 are separated from the engaging holes 43, 43 from the longitudinal direction of the tray in a manner capable of engaging and separating with the protrusions 47, 47. The inner side is arranged on the plate 30. As soon as the plate 30 is positioned at the introduction position shown by the solid line in FIG. 1, the protrusions 47 and 47 are engaged with the engaging holes 45 and 45, and the plate 30 is positioned at the introduction position.

In addition, the plate 30 has drainage openings that overlap each other so as to communicate with the drainage holes 42 of the supporting structure 40 of the other tray 1 stacked on the lower side at the protruding position. In this embodiment, the drainage opening is formed by the engaging holes 45 and 45. That is, at the protruding position of the plate 30, the engagement holes 45, 45 whose engagement with the protrusions 47, 47 are released function as drainage openings.

1 and 5, the plate 30 faces the drainage space F of the support structure 40 from the lower side, and the surface facing the drainage space F is formed as a water receiving surface 39 (see Figure 3). . Particularly in the present embodiment, the water receiving surface 39 is formed by a recessed guide groove that guides the received water to the engagement holes 45 and 45 as drainage openings.

In addition, in the present embodiment, the main body 10 has a through hole 19 (see FIGS. 1 and 2) through which water can be drained from the housing space S toward the water receiving surface 39 of the plate 30 located at the protruding position in the bottom wall 10c. Especially in this embodiment, the through holes 19 are respectively provided at the four corners of the bottom wall 10c. Furthermore, the main body 10 has a guide groove for guiding the water in the storage space S to the four through holes 19 on the bottom wall 10c. Especially in this embodiment, the guide grooves are provided on the surface 10ca of the bottom wall 10c facing the accommodating space S as shown in FIG. 2 and have: two extending so as to cross the center of the substantially rectangular bottom wall 10c A first guide groove 11a; two second guide grooves 11b extending along the same long side wall 10b near the two long side walls 10b of the main body 10 to communicate with each of the two first guide grooves 11a . In this case, both ends of the second guide groove 11 b are connected to the through hole 19.

In the case of stacking a plurality of stacked pallets 1 constructed as above to be used, the rotating plates 30 of the state switching parts 20 on both sides of each stacked pallet 1 to be stacked are rotated toward the protruding position, Each of the rotating plates 30 is placed and supported on the top surface 40a of the supporting structure 40 of the other laminated pallet 1 adjacent to and located on the lower side. According to this, the storage space S is maintained (secured) between the stack-type trays 1, resulting in a use state (see FIG. 5). An example of this state of use is shown in FIG. 6. In this example, five stacked trays 1 are arranged in the cold storage box 70 in a stacked state, and the squid 72 can be housed in a state where ice 73 and the like are added to each storage space S to be packed.

Furthermore, in this state of use, the water in the storage space S of each stacked tray 1 is guided to the through holes 19 via the guide grooves 11a, 11b, and passes through the bottom wall 10c of the main body 10 from the through holes 19 and rotates. The gap between the plates 30 flows to the water receiving surface 39 of the rotating plate 30. The water received by the water receiving surface 39 flows into the engagement holes 45, 45 as drainage openings, and passes through the supporting structure 40 of the other laminated tray 1 stacked on the lower side aligned with the engagement holes 45, 45 The drainage hole 42 flows down to the drainage space F of the other stacked tray 1. The water flowing down to the drainage space F is discharged to the outside as it is, or flows through the engagement holes 45 and 45 and the drainage hole 42 in order to another drainage space F on the lower side and is finally discharged to the outside.

On the other hand, when the stacked trays 1 are not used but are stored in a stacked state, the rotating plates 30 of the state switching parts 20 on both sides of each stacked tray 1 are rotated toward the introduction position to make the body part 10 is located in a position as embedded in the containing space S of another stacked tray 1 stacked on the lower side. According to this, as shown in FIG. 4, a storage state in which the stack height is lower than the use state can be created.

As described above, according to the stacked pallet 1 of this embodiment, since the rotating plate 30 of the state switching section 20 is moved between the protruding position and the introduction position at both ends of the main body section 10, the use state and In the stored state, it is not necessary to switch the direction of the tray every time the state is switched like the stacked tray disclosed in the aforementioned Non-Patent Document 1, and the handling operability (workability) is good.

Furthermore, in this embodiment, since the laminated tray 1 is integrally molded by resin, the occurrence of gaps due to the assembly of metal and resin like the laminated tray disclosed in Non-Patent Document 1 can be avoided. It can avoid the intrusion and accumulation of foreign objects in this gap. Furthermore, if it is possible to remove parts where dirt is likely to accumulate in this way, cleaning becomes easy, and therefore, it is possible to perform sufficient cleaning to prevent accumulation of foreign matter and the like (therefore, it is possible to prevent a stuffy smell). Moreover, since the entire tray is formed of resin, the entire tray is light and inexpensive. Moreover, since there are no sharp burrs or edges of metal, the safety is also good, and the storage body for storing the stacked tray will not be scratched. Furthermore, in relation to the integral molding of the resin, in this embodiment, the tray 1 may be formed of a colored transparent resin, for example, a transparent resin slightly bluish (of course not limited to blue, but any color may be used). In order to be able to visually recognize the existence of the contents in the storage space S enclosed in the stacked state of the trays from the outside. This kind of transparent resin has a good appearance and is effective when a tray is used to contain, for example, squid. In addition, this point is also the same in the second embodiment described later.

Furthermore, in this embodiment, since the stacked tray 1 rotates the main body 10 between the protruding position and the introduction position, it is possible to move the plate 30 between the protruding position and the introduction position with one hand. . Moreover, because of this situation, the plate 30 is positioned against the main body 10 at the protruding position and the introduction position, so that it is possible to prevent accidental switching between the use state and the storage state.

Moreover, in this embodiment, the support structure 40 delimits the drainage space F outside the accommodating space S, and at the same time has drainage holes 42 leading to the drainage space, and the plate 30 has: to be stacked at the protruding position The drainage openings 45 overlap each other in such a way that the drainage holes 42 of the support structure 40 of the other tray on the lower side communicate with each other, so that good drainage to the outside can be ensured.

Moreover, in this embodiment, the main body 10 has the bottom wall 10c with the guide grooves 11a, 11b and the through hole 19 that can discharge water from the accommodating space S toward the water receiving surface 39 of the plate 30 located at the protruding position, so that it can accommodate The water in the space S is guided to the drainage structure of the state switching part 20 through the through hole 19, and it is possible to ensure that the water from the storage space S is further well drained to the outside.

In this case, the upper end of each side wall 10a, 10b is formed with the flange part 17 which is bent into an L shape and protrudes to the outside. Moreover, at both ends of the main body 10 in the longitudinal direction (the short side wall 10a side) are respectively provided with a state switching section 20 that can switch between the use state (the state of FIG. 15) and the storage state (the state of FIG. 16). (State of FIG. 15) In a state where the tray 1A is stacked up and down, a storage space S is secured between the trays 1A and 1A. This storage state (the state of FIG. 16) fills the storage with the tray 1A stacked up and down The trays 1A and 1A can be fitted into each other in the form of the space S.

The state switching unit 20 has: a protruding position (the position shown in FIGS. 14 and 15) that is installed on the main body 10 and that corresponds to the aforementioned use state and an introduction position (the position shown in FIG. 13) that corresponds to the aforementioned storage state The plate 30A that moves between; the supporting structure 40 that supports the plate 30A at the protruding position of the other pallet 1A stacked on the upper side and secures the storage space S (refer to FIG. 15) between the stacked pallet 1A . In this case, the supporting structure 40 is formed integrally with the main body 10 by resin, and as the resin forming the main body 10 and the supporting structure 40, polycarbonate (PC) or polystyrene ( polystyrene)(PS), etc.

The support structure 40 constituting the state switching portion 20 is the same as the aforementioned first embodiment, and the longitudinal ends in the storage space S are adjacent to the short side walls 10a of the main body 10, and are regarded as being from the bottom of the main body 10 The cross section of the wall 10c extending so as to stand upright upward is formed as an L-shaped bulge, and it extends along the short side wall 10a with a predetermined gap C between the wall 10c and the long side wall 10b. Specifically, each of the support structures 40 has: a top surface 40a extending from the short side wall 10a side of the main body 10 toward the accommodating space S with a predetermined width; and a top surface 40a that is erected from the bottom wall 10c of the main body 10 The two first side surfaces 40b extending at a predetermined height and facing the long side wall 10b; the second side surface 40c connecting the first side surfaces 40b and extending slightly parallel to the short side wall 10a of the main body 10, according to Therefore, a drainage space F is defined outside the storage space S. In this case, the portion of the short side wall 10a of the main body 10 that faces the drainage space F is excluded, so that the drainage space F is exposed to the outside (see FIG. 7). That is, the stacked tray 1A is due to the existence of the drainage space F, and its longitudinal end portions are recessed inward to form a recessed shape.
