[Industrial applications]

 The present invention relates to a synthetic resin molded product provided with a slip stopper, which is mainly used for trays, tableware, etc., but can also be used for other pallets, tables, shelves, floors, etc.

[0002]

[Prior Art]

 In recent years, almost all synthetic resin molded products have been widely used as containers for foods and the like. The reason is that wood products and metal products are not suitable for cleaning, and they are unsanitary due to corrosion and rusting due to water absorption during cleaning, and they are heavy and heavy and have a short service life. is there.

In comparison, synthetic resin molded products have stable quality, can be produced in large quantities, are light and easy to handle, and are hydrophobic against water, so they do not rot or rust. In addition, it can be easily washed off dirt, and it has a wide range of uses because it has excellent aspects such as hygiene for food applications.

However, these synthetic resin molded products have a problem that they are extremely slippery depending on the application, and accidents due to slipping often occur, which is very dangerous. For example, in trays made of synthetic resin products used in cafeterias, the tableware placed on the tray sometimes slipped off when carrying the tableware. In addition, when an article is placed in a container that is made of synthetic resin and is transported, there is a risk that the article may slip and the center of gravity may shift, causing imbalance and falling.

[0005]

[Problems to be solved by the device]

 As a method of preventing these slips, for example, in the tray etc., the surface of the tray is provided with irregularities such as a decorative pattern to prevent it from slipping, but by providing this irregularity, the contact area is reduced. It was slippery.

As another method, a non-slip rubber sheet or the like is attached to prevent slippage, but if it is used for many purposes such as washing with water, the molded product and the sheet may peel off, which may result in long-term use. Could not be used over.

The present invention has been made in view of the above problems, and is a synthetic resin molding provided with a non-slip having excellent physical properties such as anti-slip property, cleaning property, abrasion resistance, strength property, and impact resistance. It provides equipment.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the synthetic resin molded article having a non-slip of the present invention is a synthetic resin molded article obtained by combining a thermoplastic polyurethane resin sheet or a thermoplastic polyurethane film and a cloth to form an integrated anti-slip material. The polyurethane resin surface is formed on the outer surface of the part where slip prevention is required.

The thermoplastic polyurethane resin used in the present invention includes polyester-based, polyether-based, polycarbonate-based, polycaprolactone-based, etc., but a polyether-based resin excellent in hydrolysis resistance and mildew resistance is used. Is good. The surface of the thermoplastic polyurethane resin surface may be provided with necessary irregularities depending on the application.

The cloth joined and integrated with the thermoplastic polyurethane resin sheet or film is a woven or non-woven fabric made of chemical fibers and natural fibers, and a pattern printed with a pattern may be used if necessary. .. Also, an adhesive layer may be provided. Filaments, spun yarns, and slit yarns are used as yarns for woven and non-woven fabrics, but spun yarns are preferable in view of fusion property, adhesiveness, compatibility with synthetic resin during molding. ..

Any resin may be used as the synthetic resin used in the molded product. For example, as the thermoplastic resin, vinyl chloride resin, styrene resin, olefin resin, polyamide resin, polyester resin, acrylic resin may be used. Resins and polycarbonate resins are used. As the thermosetting resin, melamine resin, phenol resin, urea resin, epoxy resin, unsaturated polyester resin, etc. can be used. Antioxidants, UV absorbers, antistatic agents, anti-twist agents, foaming agents, fillers, etc. can be added to these resins depending on the application.

The synthetic resin molding method may be manufactured by any molding method, and for example, injection molding, extrusion molding, vacuum molding, casting method and the like are used. The location of the anti-slip is different for each container, but for containers such as trays and trays, it is installed on the bottom surface that is the contact surface with the product, and pallets and steel plates are installed on the surface.

[0013]

[Action]

 Since the thermoplastic polyurethane resin surface is provided at the place where the synthetic resin molding is required to be non-slip, it is flexible and has a large frictional resistance, so that the contained article can be held in a stable state without slipping or collapsing.

[0014]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. (Example 1) 1 is a polypropylene tray main body, and a plain weave base cloth 2b (20/1 × 20/1, 27 × 30 / inch) made of cotton and polyester fibers is provided on the bottom with a polyurethane resin. The sliding base material 2 to which 0.5 mm of film 2a is attached is integrated with the tray main body 1 so that the polyurethane resin film 2a is the outer layer surface.

(Example 2) 11 is a polypropylene tray mainly, the bottom surface of which is printed with a pattern 13 on a non-woven fabric 12b made of cotton and polyester fibers, and a thermoplastic polyurethane resin transparent film 12a 0.5 mm is provided on one side. The laminated sliding base material 12 is integrated with the tray main body so that the polyurethane resin film 12a is the outer layer surface.

In the above embodiment, the example of the tray and tray has been described, but the present invention is not limited to this, and it goes without saying that it is also used for pallets, shelf boards, various floor boards and the like. ..

[0017]

[Effect of the device]

 The present invention uses a non-slip material made by adhering and integrating a thermoplastic polyurethane resin sheet or a thermoplastic polyurethane film to a place where slippage of a synthetic resin molding device is required so that the polyurethane resin surface is the outer surface. Since it is related to the synthetic resin molding equipment provided, it is flexible and has a large frictional resistance even when the goods are stored or placed in the equipment, and the stored goods are stable without slipping or collapsing. Can be transferred at.

Further, since the polyurethane resin is integrally bonded to the molded product, it does not peel off even by washing or the like, has strength, and can be used for a long period of time.
