Abstract

(57) [Summary] [Object] To provide a tray having a non-slip surface which has good adhesion of the surface layer to a hard base material layer, does not cause peeling, is simple, inexpensive, and has a good finished appearance. [Structure] Base material layer 1 made of SMC, premix, ABS, polycarbonate, nylon or vinyl chloride
The surface treatment layer 2 made of two-pack type urethane, two-pack type acrylic or one-pack type olefin is applied to the upper surface of the above in advance, and then two-pack type acrylic urethane or two-pack type urethane is sprayed to form the surface layer 3. Tray.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tray, that is, a shallow dish tray, and more particularly, to a tray having a non-slip surface.

[0002]

[Prior art]

 Tray has long been used as a tray for transporting a relatively large number of dishes and other dishes, and recently there has been a demand for resin-molded trays in terms of mass productivity, easy painting, and low cost. Is popular. However, the resin-molded tray has a smooth surface, which makes it unstable for tableware transportation. Therefore, conventionally, a resin-molded tray having a non-slip surface is known.

There are generally three types of conventional surface-slip processing techniques for resin molded trays, one of which is a means for processing a special mold, for example, a surface of a mold with a satin pattern, and the other is 2 The heavy molding means, No. 3, is an adhesion means.

[0004]

[Problems to be solved by the device]

 However, since the surface of the base material layer of the hard resin itself has a satin pattern, the above-mentioned No. 1 has a poor anti-slip effect and may not be able to achieve the purpose. Since there is a risk of peeling, there was a concern that measures such as reinforcing the clamp band along the peripheral surface of the tray and cost would be required.

The object of the present invention is to provide a non-slip surface that has a good adhesion of the surface layer to a hard base material layer, does not peel off even when washed by boiling, and has a simple and inexpensive appearance and a good finished appearance. Is to provide a tray with.

[0006]

[Means for Solving the Problems]

 In order to achieve the above purpose, the tray according to the present invention has a base material layer made of SMC, premix, ABS, polycarbonate, nylon or vinyl chloride, and a two-component urethane provided on the top surface of the base material layer, and a two-component type. And a surface layer made of a two-pack type acrylic urethane or a two-pack type urethane provided on the upper surface of the ground treatment layer.

[0007]

[Action]

 Since the surface layer is sprayed after applying the undercoat layer to the hard base material layer, a non-slip surface having good adhesion (adhesion) of the surface layer to the base material layer is formed.

[0008]

【Example】

 As shown in Fig. 1, a base material layer 1 made of ABS is provided with a base treatment layer 2 coated with a two-component urethane, and the two-component urethane is sprayed on the entire top surface of the layer 2 to form a surface layer. When 3 is formed, a soft type anti-slip process is performed.

When the two-component acrylic urethane is sprayed onto the entire upper surface of the base treatment layer 2 made of the two-component urethane to form the surface layer 3, a relatively hard type anti-slip process is performed.

[0010]

[Effect of device]

 The tray according to the present invention is prepared by applying a two-component urethane, a two-component acrylic or a one-component olefin on the upper surface of a base material layer made of SMC, premix, ABS, polycarbonate, nylon or vinyl chloride in advance. Since the surface layer is formed by spraying two-component acrylic urethane or two-component urethane, the adhesion of the surface layer to the base material layer is good, it does not peel off even after boiling washing, and it is relatively simple and inexpensive. It has become possible to provide a non-slip surface with a good appearance.
