Description

This invention relates to an assembly-type tray. Patent Document 1 discloses an assembly-type tray (waterproof tray) whose shape can be changed between tray form and storage form. This assembly-type tray comprises a bottom, a foldable frame-shaped wall, and a waterproof sheet covering the bottom and wall. Furthermore, when used in tray form, a separate bottom plate is provided at the bottom. In tray configuration, it forms a box-like structure with an open top, allowing for secure storage of contents while preventing leaks. In storage configuration, the bottom plate can be removed and the container folded for compact storage. Japanese Patent Publication No. 2017-74961 This is a perspective view of an assembly tray in tray form according to one embodiment of the present invention.This is a plan view of an assembled tray for storage according to one embodiment of the present invention.This is a plan view of the surface of the assembly tray in its disassembled and unfolded state.This is a plan view of the underside of the assembly tray in its disassembled and unfolded state.This is a plan view of the plate-like material before forming the first and second storage compartments of the aforementioned assembly tray. The following describes one embodiment of the present invention with reference to the drawings. Figure 1 is a perspective view of the assembled tray in tray form. Figure 2 is a plan view of the assembled tray in storage form. Thus, the assembled tray 1 of this embodiment can be assembled into the "tray form" as shown in Figure 1 and used as a tray, and when not in use, it can be unassembled as shown in Figure 2 and folded in half to become the "storage form". As shown in Figure 1, the assembly tray 1, in its tray configuration, comprises a rectangular base 10 and four side walls 12 rising from the periphery of the base 10. The four corners of the side walls 12 maintain their shape by engaging with connecting parts 7. This results in the assembly tray 1 becoming a box-shaped body with an open top. In the tray configuration shown in Figure 1, for example, a cooler box used for fishing, a tackle box, etc., can be stored in the assembled tray 1. The tray configuration prevents liquid from leaking out of the cooler box, thus preventing the interior of the vehicle or room from getting wet or soiled. Furthermore, the tray configuration can store not only cooler boxes and tackle boxes, but also various other types of box-shaped containers. Figure 3 is a plan view of the front surface of the disassembled and unfolded assembly tray. Figure 4 is a plan view of the back surface of the disassembled and unfolded assembly tray. The front surface (front side) 2 in Figure 3 is the side that becomes the outer periphery of the tray in the tray configuration shown in Figure 1. The back surface 3 in Figure 4 is the side that becomes the inner periphery of the tray in the tray configuration shown in Figure 1. The assembly tray 1 comprises a flat, plate-like material 4 having waterproof and flexible properties, and four connecting parts 7. The plate-like material 4 is, for example, made of resin, and in this example, is a thin, roughly rectangular plate. When the plate-like material 4 is formed from resin, ethylene vinyl acetate copolymer (EVA), polyvinyl chloride (PVC), thermoplastic rubber (TPR), etc., can be used. Ethylene vinyl acetate copolymer is particularly suitable as the material for the plate-like material 4 due to its heat resistance. Each connecting part 7 has a pair of adjacent engaging parts 5 (male) and engaged parts 6 (female) at the four corners of the surface 2 of the plate-like material 4 of the assembly tray 1. While buckles are exemplified for the connecting parts 7 in this embodiment, other means such as hook-and-loop fasteners may be used as long as the engaging parts 5 and engaged parts 6 can engage and be firmly joined. The plate-like material 4 has a rectangular bottom plate portion 11 positioned in its center, which becomes the bottom portion 10 when it is in tray form. The plate-like material 4 also has four side plate portions 13, 13, 14, 14, each provided on the four sides of the bottom plate portion 11, which become the side walls 12 (see Figure 1) when it is in tray form. Specifically, wide rectangular side plate portions 13, 13 are formed on the two long sides of the bottom plate portion 11. Rectangular side plate portions 14, 14, narrower than the side plate portions 13, are formed on the two short sides of the bottom plate portion 11. The width (height when standing) of the side plate portions 13 and 14 is the same. A thin-walled portion 15 is formed at the boundary between the bottom plate portion 11 and the side plate portions 13, 14, which is thinner than the rest of the bottom plate portion 11 and the side plate portions 13, 14. The side plates 13 and 14 can be bent relative to the bottom plate 11 at the thin-walled section 15. Each side plate 14 is provided with a handle 47 that protr
