Hereinafter, with reference to FIGS. 1 to 11, the laminate and its manufacturing method according to the first embodiment of the present invention will be described. The laminate 10 is a body of the box 20 and the foam Y. The box 20 has a top plate 1, a bottom plate 2 and a side plate 3. The foam Y is filled in the hollow X of the box 20. The box 20 is a member covering the outer side of the foam Y which is the core material. In this example, the laminate 10 is substantially rectangular when viewed from above, and the four corners are rounded (arc) shapes. Therefore, it is suitable for multi-layer display and can prevent customers from being injured. Furthermore, for the corner member 7 of the four corners, a material different from the material of the box body 20, such as resin, can also be used. In this case, the corner member 7 is embedded in the cut corner of the box body 20. When the laminate 10 is a polygon with 6 or more corners, the arc shape may also be omitted.

In the laminate 10, as the box body 20, metals such as steel plates, aluminum plates, and stainless steel plates, or non-metal plates such as resin plates containing reinforced fibers can be cited. Among them, metal plates such as steel plates with a thickness of 0.25 to 0.35 mm are preferable in terms of being lightweight and having high strength, and being able to bond with the core material, that is, the foam to form a single body.

In the laminate 10, the box body 20 may be in the shape of a container in which the top plate 1, the bottom plate 2 and the side plates 3 are integrated, or may be formed by fitting a plurality of members. In this example, the box body 20 is a fitting body of a lid-shaped upper member 1A with a lower opening and a box-shaped lower member 1B with an upper opening. The upper member 1A has a top plate 1 and an upper side plate 3, and the lower member 1B has a bottom plate. 2 and the lower side panel 4. Both the upper side plate 3 and the lower side plate 4 have four side plates, namely, left and right side plates and front and rear side plates. That is, the inner dimensions of the length, width and height of the upper member 1A are approximately the same as the outer dimensions of the lower member 1B (refer to FIG. 5). Thereby, the fitting body of the upper member 1A and the lower member 1B has a structure in which the entire lower member 1B except the bottom plate 2 is covered by the upper member 1A. For the fitting of the upper member 1A and the lower member 1B, it is not necessary to separately provide a locking portion, and it is only necessary to cover the upper member 1A on the lower member 1B with substantially no gap. Preferably, the upper member 1A and the lower member 1B are processed by sheet metal.

In addition, although there is no particular limitation on the joining form of the side plates of the upper member 1A and the lower member 1B, for example, as shown in FIGS. 6 and 7, the short side direction of the upper side plate or the lower side plate as the outer periphery of the fitting body The front end is in a state of being folded toward the inside, and preferably, the front end exposed to the outside is rounded. That is, as shown in FIG. 6, the short-side front end 311 of the side plate 31a of the upper member 1A is a folded bent portion, and the front end 311 is exposed to the outside in a rounded shape. Therefore, it will not hurt the hand of the customer who takes the product. In addition, as shown in FIG. 7, the short-side front end 321 of the side plate 32a of the upper member 1A is a folded bent portion, and the front end 321 is exposed to the outside. Rounded. Therefore, it will not hurt the hand of the customer who takes the product. Furthermore, in the side plate 32a of FIG. 7, the difference from the side plate 31a of FIG. 6 is that the height of the side plate of the lower member 1B is small, and the height of the inner plate of the side plate of the upper member 1A that is folded toward the inside is small. aspect. In addition, in FIGS. 6 and 7, the state may be upside down, that is, the upper member 1A may be the lower member and the lower member 1B may be the upper member. In this case, the rounded corner of the bent portion exposed to the outside becomes the upper end (tip).

In addition, the box body 20 is not limited to the form shown in FIGS. 1 and 2, and as the outer shape of the box body, a circle, an ellipse, a polygon other than a quadrilateral, and an indefinite shape when viewed from the top may be mentioned. That is, the side panel of the present invention includes a round side panel (peripheral side panel), an elliptical side panel, a polygonal side panel, and an indefinite side panel.

The core material of the laminate 10, that is, the surface of the foam Y and the inner peripheral surface of the box 20, are bonded or welded (hereinafter referred to as "bonding"), and the two are integrated. That is, the foam Y is formed by injecting a foaming agent stock solution into the hollow portion of the box 20 from the outside, and foaming and hardening inside, and there is no internal gap. Thereby, it is different from prefabricating a foam of a predetermined shape and using an adhesive or double-sided tape to mount the top plate, bottom plate and side plates on the foam layer. That is, in the laminate 10 of the present invention, the adhesive or double-sided tape can be omitted, and the box and the foam can be firmly integrated.

Examples of foams include synthetic resin foams such as polyurethane foam, polyisocyanate foam, polystyrene foam, phenol foam, and polyethylene foam. The foaming agent stock solution of the foaming agent is obtained by spitting out the foaming agent stock solution into the box 20 and reacting, foaming, and hardening in the box 20. Among the foams exemplified above, rigid or semi-rigid polyurethane foam, polyisocyanate foam, and polystyrene foam are preferred, and particularly rigid or semi-rigid polyurethane foam is more preferred.

In the laminate 10, the legs 62a, 62b, and 62c of the anti-tilt member 6 are formed near the side end of the top plate 1, the side end in the short side direction in this example, and at a predetermined distance along the long side direction. The locking holes 8a, 8b, 8c. Thereby, the installation and disassembly of the anti-tip tool 6 can be performed freely. Moreover, the installation of the anti-dumping member 6 is stable. In addition, a tipping prevention tool 6 is provided on the layer board 10. In this way, for example, when it is set as a downwardly inclined layer board, it is possible to prevent the displayed goods from slipping forward. In the case where the layer plate 10 is provided with the anti-tip element 6, it is only necessary to insert the feet 62 a, 62 b, and 62 c of the layer plate 10 into the locking holes 8 a, 8 b, and 8 c of the layer plate 10.

In addition, in the laminate 10, a foaming agent stock solution injection port 5 is formed in the box body 20, and the injection port 5 is closed by a cover material 50 (refer to FIGS. 2 and 11). The foaming agent stock solution injection port 5 is a hole for inserting the front end of the nozzle of the foaming agent stock solution injector not shown. The formation position of the foaming agent stock liquid injection port 5 can be any one of the top plate 1, the bottom plate 2 and the side plate 3 of the box body 20. In this example, it is one of the two side plates 3a, 3a in the short side direction. When the box body 20 is a fitting body of the upper member 1A and the lower member 1B, the injection port 5 is respectively formed in the position corresponding to the upper member 1A and the lower member 1B. Thereby, the injection port 5 is formed in the fitting body of the upper member 1A and the lower member 1B. As the cover material 50, as long as it can hide the injection port 5, the decorative sticker etc. which apply|coated an adhesive on the adhesive surface can be mentioned.

In the laminate 10 of the present invention, as the joining form of the side plates of the upper member 1A and the lower member 1B, there is no particular limitation. Except for FIGS. 5 to 7, for example, as shown in FIG. 8, the side plate 33a of the upper member 1A The front end side is bent from the center in the height direction toward the inner side in the left-right direction to form a step, and the side plate 42a of the lower member 1B is overlapped at the front end of the bending. In the shape of the side plate in Fig. 8, the corners of the side plate do not protrude outward, so the hand of the customer who takes the product will not be hurt. In addition, as shown in FIG. 10, in FIG. 7, the front end portion of the folded bending portion of the side plate 32 a of the upper member 1A may be further bent inward to form a horizontal portion 322. At this time, the front end of the side plate 42a of the lower member 1B abuts against the back surface of the horizontal portion 322. Thereby, as long as the upper member 1A is covered on the lower member 1B, the positions of both can be determined. In addition, Figures 5 to 8 show the state before the foaming agent stock solution is injected, and Figure 10 shows the state after the foaming agent stock solution is injected, foamed and hardened in the box.

According to the laminate 10 of the present invention, the inner peripheral surface of the box body 20 and the outer peripheral surface of the foam Y are bonded. Or even if they are not bonded, the inner peripheral surface of the box body 20 and the outer peripheral surface of the foam Y are still joined without a gap. Therefore, even in the case of bending force, the two members still have no gap and are used as a single body. Therefore, it is lightweight and strong. In addition, there is no need to use adhesives, etc., the number of parts is small, and the core material is substantially not exposed, so the design is excellent and the display effect of the display is not reduced. In addition, the surface of the laminate 10 on which the products are placed has a little cushioning, so that an excellent display surface that does not damage the products can be formed.

Next, the manufacturing method of the laminate of the present invention will be described. The manufacturing method of the laminate of the present invention includes injecting the foaming agent stock liquid into the box from the foaming agent stock solution injection port formed in the box with the top plate, the bottom plate and the side plate, and injecting the foaming agent into the box. The step of curing the original liquid.

In the manufacturing method of the present invention, the box body 20 having a top plate, a bottom plate and a side plate is an intermediate body. Examples of the box body 20 include metals such as steel plates, aluminum plates, and stainless steel plates, or nonmetal plates such as resin plates containing reinforced fibers. Among them, metal plates such as steel plates with a thickness of 0.25 to 0.35 mm are preferable in terms of being lightweight and having high strength, and being able to bond with the core material, that is, the foam to form a single body.

In the laminate 10, the box body 20 can be a combination of the top plate 1, the bottom plate 2 and the side plates 3 The shape of an integrated container may be formed by fitting a plurality of members. In this example, the box body 20 is a fitting body of a lid-shaped upper member 1A with a lower opening and a box-shaped lower member 1B with an upper opening. The upper member 1A has a top plate 1 and an upper side plate 3, and the lower member 1B has a bottom plate. 2 and the lower side panel 4. Thereby, the fitting body of the upper member 1A and the lower member 1B has a structure in which the entire lower member 1B except the bottom plate 2 is covered by the upper member 1A. For the fitting of the upper member 1A and the lower member 1B, it is not necessary to separately provide a locking portion, and it is only necessary to cover the upper member 1A on the lower member 1B with substantially no gap. Preferably, the upper member 1A and the lower member 1B are processed by sheet metal. Hereinafter, a manufacturing method using the upper member 1A and the lower member 1B will be described.

As shown in FIG. 2, cutouts 711 and 712 are formed in the four corners of the upper member 1A and the lower member 1B, respectively, into which the corner member 7 is inserted. In addition, through holes 91a, 91b, and 91c into which the anti-tip support members 9a, 9b, and 9c are inserted are formed at predetermined positions of the lower member 1B. In addition, in the vicinity of the side end of the top plate 1 of the upper member 1A, in this example, the side end in the short side direction is formed with locking holes 8a, 8b, and 8c at a predetermined distance along the long side direction. In addition, the side plates 3a and 4a of the upper member 1A and the lower member 1B are respectively formed with foaming agent stock solution injection ports 5.

In addition, in addition to the upper member 1A and the lower member 1B, the anti-tip support members 9a, 9b, 9c and the corner members 7a to 7d are also prepared before manufacturing. The anti-tip support member 9 is arranged in the box body 20 to fix the anti-tip member 6, and a fastening longitudinal hole 94 is formed in the center of the upper part of the substantially cylindrical body, and a protrusion 92 extending downward is formed on the bottom surface . The leg portion 62 of the anti-tilt member 6 is fitted into the fastening longitudinal hole 94, and the protrusion 92 is fitted into the through hole 91 of the bottom plate 2. The protrusion length of the protrusion 92 is equivalent to the thickness of the bottom plate 2 and is not shown in FIG. 4 because it is short. In addition, as shown in Figure 3, The corner member 7 is substantially L-shaped when viewed from above, and the corner 701 is arc-shaped. The corner member 7 is fitted into the four corners of each of the upper member 1A and the lower member 1B. The corners are arc-shaped and become The shape corresponding to the corner of the box. The plate-shaped locking pieces 702 and 703 extending from the corner 701 toward both sides abut against the inner surface of each side plate of the upper member 1A or the lower member 1B, respectively. Thereby, even if the foaming agent stock solution reacts in the box 20 to foam and increase in volume, since the plate-shaped locking pieces 702 and 703 serve as stop portions, there is still no corner member 7 from the box 20. The situation where the notch 7 of the four corners falls off occurs.

First, the bottom plate 2 is lowered, and the lower member 1B is installed on the workbench. Next, the protrusions 92 of the anti-tip support members 9a, 9b, and 9c are inserted into the through holes 91a, 91b, and 91c, respectively, and the anti-tip support members 9a, 9b, and 9c are fixed to the bottom plate 2 respectively. The locking of the protrusion 92 of the anti-tip support members 9a, 9b, 9c and the through holes 91a, 91b, 91c may be such that the locking does not move when the foaming agent stock solution reacts. The protrusion 92 does not protrude from the bottom of the bottom plate 2 below. In addition, the corner member 7 is fitted into the cutout portion 712 of the four corner of the lower member 1B from the inner side to the outer side (FIG. 3(A) and (B)). Next, with the top plate 1 facing upward, the upper member 1A is fitted into the lower member 1B in a covering manner (refer to FIG. 2). That is, the lower member 1B and the upper member 1A are fitted. Thereby, a box body 20 with a hollow portion can be formed. At this time, the engaging longitudinal holes 91 of the anti-falling tool support members 9a, 9b, and 9c correspond to the locking holes 8a, 8b, and 8c of the upper member 1A, respectively. In addition, corner members 7 are arranged in the four corners of the box body 20.

Next, as shown in FIG. 9, the intermediate body, which is the box 20, is fixed with a fixing jig 150 in a manner that restricts the movement in the thickness direction. The fixing jig 150 is used to clamp the upper member placed on the top plate 1 and the lower member placed under the bottom plate 2 with the pad placed under the bottom plate 2 by connecting members such as bolts. In this example, although a plurality of long strips are used, they can also be compared to the top One of the large area of 1 or bottom plate 2 is sandwiched between the plates. Thereby, even if the foaming agent stock solution is injected into the box 20 from the outside and reacts in the box 20, the shape of the box 20 of the intermediate body can still be maintained.

Next, a step of injecting the foaming agent stock solution from the foaming agent stock solution injection port 5 formed in the box body 20 into the box body and hardening the foaming agent stock solution in the box body is performed. As the foaming agent stock solution, as long as it can form synthetic resin foam such as polyurethane foam, polyisocyanate foam, polystyrene foam, phenol foam, polyethylene foam, etc. after the reaction, known stock solution, including hardening The original solution of the foaming agent and the foaming agent is sufficient. For example, in the case of polyurethane foam, a polyol mixture containing polyol components, amine-based compounds, water, and catalysts, and isocyanate components and other foaming agent stock solutions are mixed and stirred, and injected The machine injects the obtained mixture into the box 20 from the injection port 5, and reacts, foams, and hardens in the box 20 (refer to FIG. 9).

After the foaming agent stock solution is foamed and hardened in the box 20, it becomes the foam Y. At this time, the three anti-tip support members 9a, 9b, and 9c are fixed to the bottom plate 2, and the fixed position will not slide by injecting the foaming agent stock solution. In addition, the four corner members 7a to 7d, although the arc portions protrude from the cutout portions 711, 712, because the locking portions 702, 703 abut on the inner surface of the side plate of the upper member 1A or the lower member 1B, they are not It is provided in the cutout parts 711 and 712 with a gap, and does not fall off. In this way, in the box body 20, the core material, that is, the surface of the foam Y and the inner peripheral surface of the box body 20 are adhered or tightly joined, and there is no internal gap between the two, and they become one body.

Next, it is preferable to cover the entire outer peripheral surface of the box body 20 except for the corner members 7a-7d and the locking holes 8a, 8b, 8c with a decorative sheet. In addition, it is preferable that the foaming agent stock solution injection port 5 formed in the box body 20 is covered with a cover material, which is covered by a sticker 50 in this example. Thereby, the laminate 10 having the foam Y as the core material can be obtained. And, according to If necessary, an anti-tip element 6 is provided on the layer board 10. The anti-tip element 6 can be arranged in the locking holes 8a, 8b, and 8c by locking the legs 62a, 62b, 62c of the anti-tip element 6. Thereby, when the layer board 10 is installed in a downwardly inclined forward direction, the goods can be prevented from slipping forward.

Next, referring to Figs. 12 to 14, the laminate 10a of the second embodiment of the present invention will be described. In FIGS. 12 to 14, the same components as those in FIGS. 1 to 11 are given the same reference numerals and descriptions are omitted, and differences are mainly described. That is, in the laminate 10a of Figures 12 to 14, the difference from the laminate 10 of Figures 1 to 11 lies in the following points: the box body 20a is attached to the left and right side panels of the box body 20 and the second left and right sides are installed Side plates 17, 17; the corners of the layer plate 10a are not rounded; the layer plate 10a is not formed with through holes 91a, 91b, 91c for the anti-tip support members 9a, 9b, 9c, and for the anti-tip member 6 The locking holes 8a, 8b, 8c into which the legs 62a, 62b, 62c are inserted; and the second left and right side plates 17, 17 are formed on the left and right side plates of the box body 20a.

That is, the layer plate 10a has an integral body which is an integral body of the box body 20a and the foam body Y. The box body 20a has a top plate 1a, a bottom plate 2a, left and right side plates 3a', and front and rear side plates 3b'.
