Description

[Detailed description of the invention] (Industrial field of application) This invention provides a covering layer of synthetic resin with hinge properties on the surface of extruded and foamed styrene resin.
This relates to a side plate for a synthetic resin box, which is provided with a transfer layer having a glossy color on the coating layer, and when the side plate is folded to assemble the box, the coating is applied to the part of the side plate corresponding to the corner of the box. Even if the resin layer is left in place and the resin layer is cut into a V-shape from the inside and bent, it is suitable for bending and will not be damaged.The uppermost transfer layer has excellent gloss and can form patterns, making it a side plate for boxes with an extremely beautiful appearance.

(Prior Art and Problems) A synthetic resin layer with hinge properties alone has good hinge properties when cut into a V-shape and folded, but the surface condition is poor and even though it has some gloss, it is not sufficient. On the other hand, glossy synthetic resins such as polystyrene resin and acrylic resin have poor hinge properties.

Therefore, by coating a synthetic resin layer with hinge properties with a glossy transfer layer, such as a lacquer-like gloss, it is possible to create an extremely beautiful side panel with hinge properties and a rich surface gloss. Obtainable.

(Means and Effects for Solving the Problems) As shown in the drawing, the present invention provides a coating layer 2 of synthetic resin with hinge properties on the surface of extruded and foamed styrene resin, and a glossy coating layer 2 is provided on the surface of the extruded foamed styrene resin. The contents include a side plate for a synthetic resin box provided with a transfer layer 3 having a certain color tone.

As synthetic resins with hinge properties, for example, if the foamed resin of the main body is styrene-based, styrene-butadiene-based copolymer resins that are compatible with it, such as commercially available K resin (manufactured by Philips Co., Ltd.), clearene (electrochemical It is preferable to use products such as those manufactured by Kogyo Co., Ltd., as they have excellent adhesion. At the same time, if a resin with a color different from that of the foamed resin molded body of the main body is used as the coating resin layer, the molded body will have a beautiful design, and its heat and cold insulation effects will be improved.

As the transfer film, a commercially available film whose transferred surface has a lacquer-like luster, for example, is used. A suitably colored film may also be used. Printing may be used instead of a transfer film, but since the main body is polystyrene foam, there is a risk of it being attacked by solvents.
Moreover, printing on the same line is not preferable from a sanitary standpoint. The transfer process does not have these drawbacks;
It is possible to easily transfer to a desired location on the same line.

FIG. 2 is a perspective view of a box made by folding the side plate 1 of the present invention into a square and assembling the bottom plate, and FIG.
It is a front view of the side plate 1, in which a synthetic resin coating layer 2 with hinge properties is provided on the surface of an extruded styrene foam resin layer, and a transfer layer 3 is provided on the coating layer 2. When assembling the box, on the inside of the extruded polystyrene foam resin layer corresponding to the corners of the box, leave the coating resin layer and cut a V-shaped cut with the angle of the cut surface perpendicular to the board surface or at 45 degrees. A recess 4 or serration is provided at which a square box can be made by folding, but hexagonal or octagonal boxes can also be made depending on the angle of the cut surface.

As mentioned above, the present invention improves the conventional drawbacks.
It is a side plate for boxes that has hinge properties, has excellent gloss, and has a beautiful appearance.
