 The present invention relates to a plastic shelf for a food transport trolley, and more particularly to a plastic shelf for a food transport trolley having an antibacterial agent and / or a fungicide.

[0002]

[Prior art]

 For example, when eggs are shipped from a poultry farm or displayed in large quantities at supermarkets and other sales floors, food transport carts with multi-tiered shelves are used. The shelves for food transport trolleys usually include metal shelves and plastic shelves. Metal-made shelves are bulky and rust when used for a long period of time. But the demand is increasing.

[0003]

[Problems to be solved by the invention]

 However, such conventional plastic shelves for food transport trolleys have not been subjected to antibacterial processing or antifungal processing. Therefore, it is known as a pathogenic Escherichia coli O-157, which has become a topical causative agent of food poisoning today, and a causative agent of hospital-acquired infections on the surface of plastic shelves for some reason during use. Staphylococcus aureus (MRSA), Salmonella bacteria causing food poisoning of raw eggs, and the like adhered, and there was a possibility that they would propagate on the surface of the shelf.

[0004] Similarly, various molds such as black mold, ketomium, black mold, blue mold and black mold must be propagated on the surface of the plastic shelf board. Conventionally, as a countermeasure against bacteria and mold on such plastic shelves for food transport trolleys, for example, the plastic shelves are periodically removed from the trolley and dipped in boiling water, or an antibacterial agent is applied to the surface of the shelves. Only temporary measures were taken, such as spraying.

[0005]

[Purpose of the invention]

 The purpose of this invention is to provide a plastic shelf board for food transport trolleys that has antibacterial and / or antifungal properties not only on the board surface but also inside the board.

[0015]

[Action]

 According to the invention as set forth in claims 1 to 6, an antibacterial agent and / or a fungicide are added to the synthetic resin to intermediately produce a shelf board molding material, which is then placed in the mold. The plastic shelves having the antibacterial effect and / or the antifungal effect are manufactured by putting and compression molding. As a result, bacteria and mold spores attached to the surface of the plastic shelf are inhibited from growing or killed, so that bacteria and mold do not propagate on the surface of the shelf. Moreover, the plastic shelf has antibacterial and antifungal properties not only on the surface of the shelf but also on the inside of the shelf, so that, for example, the surface of the shelf is shaved or worn during use. However, it maintains good antibacterial and antifungal properties.

In particular, according to the invention of claim 2, since a special cationic antibacterial agent having an antibacterial agent and a fungicide is added to the synthetic resin to form the shelf board molding material, there has been a recent problem. Good antibacterial properties are obtained even against toxic bacteria such as pathogenic Escherichia coli O-157, Staphylococcus aureus (MRSA) and Salmonella.

In the invention according to claim 4, the compounding ratio of the synthetic resin, which is a component of the molding material for the shelf board, to the antibacterial agent and / or the antifungal agent is set to 9: 1. Antibacterial and antifungal effects can be obtained at relatively low cost.

[0019]

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a use state of a plastic shelf board for a food transport trolley according to an embodiment of the present invention. In FIG. 1, reference numeral 10 denotes a plastic shelf board for a food transport trolley (hereinafter, may be simply referred to as a plastic shelf board) according to one embodiment. The plastic shelf board 10 is an egg (chicken egg) E which is an example of food. Is a plate material of a predetermined size on which is placed, and is arranged in four stages on an egg transporting cart 11 which is an example of a food transporting cart. The egg transporting trolley 11 has a vertically long dorsal pipe plate 13 having a pair of casters 12 arranged at the lower part of both sides bent forward, and both sides bent forward of the dorsal pipe plate 13 in plan view. It has two U-shaped pipe plates 14 on both sides of which a caster 12 is provided.

On each inner surface of the pipes 14 on both sides, a total of four pairs of latch plates 15 having an L-shaped cross section, on which the side walls of each plastic shelf board 10 are latched at predetermined intervals and at opposing height positions. It is fixed. Accordingly, each plastic shelf board 10 is supported between the L-shaped horizontally bent lower portions of the corresponding plate of the latch plate 15.

Next, each plastic shelf board 10 will be described in detail. Each of the plastic shelves 10 can bend a front shelf 16 having a relatively high front wall and a rear shelf 17 having a relatively low rear wall by a hinge (not shown). It is a concatenation. The plastic shelf board 10 is one in which the front shelf section 16 and the rear shelf section 17 are individually injection-molded by using an injection mold using a shelf board molding material. The shelf plate molding material is mainly made of ABS (trade name: TECHNO ABS 150 Technopolymer Co., Ltd.), which is a kind of synthetic resin, and contains a special cationic antibacterial agent which is an antibacterial agent and a fungicide. : 1 added at a compounding ratio. The compounding ratio can be changed within a predetermined range according to the resin material and the purpose of use (such as the use environment of the shelf).

In using the plastic shelf board 10 for a food transport trolley, each plastic shelf board 10 that has been folded around the hinge is straightened, and then the L of the latch plate 15 of the corresponding step is used. Each of the plastic shelves 10 is set between the horizontally bent lower portions of the character shape. Then, the eggs E in a pack (pack case) are placed on each plastic shelf board 10. When transporting, the operator pushes the egg transport cart 11 by hand.

Since a special cationic antibacterial agent which is an antibacterial agent and a fungicide is added to the synthetic resin, bacteria and fungal spores adhered to the surface of the plastic shelf plate 10 are inhibited from growing. Be killed or killed. Thereby, bacteria and mold do not propagate on the surface of the shelf 10. Moreover, since the plastic shelf board 10 has an antibacterial agent and a fungicide mixed in the resin, it has antibacterial properties and antifungal properties not only on the surface of the board but also inside the board. In addition, the same antibacterial property can be exhibited even in a hard-to-clean portion such as a corner of a shelf board. As a result, for example, even if the surface of the plastic shelf board 10 is worn for some reason during use, a good antibacterial effect and a good antifungal effect can be maintained. In addition, since a special cation-based antibacterial agent is used as an antibacterial agent / antifungal agent added to the synthetic resin, for example, O-157 which is a pathogenic Escherichia coli, Staphylococcus aureus (MRSA), It has good antibacterial properties against bacteria such as Salmonella. Of course, it is also excellent in mold resistance.

Furthermore, since the mixing ratio of the synthetic resin and the special cationic antibacterial agent is set to 9: 1, a good antibacterial effect and a fungicidal effect can be obtained at a relatively low cost. Since the plastic shelf can be folded into two, the plastic shelf 10 can be easily attached to and detached from the egg transport trolley 11. For example, when the plastic shelf 10 is removed from the trolley 11 and stored in a warehouse, The plastic shelf board 10 becomes compact, and the degree of freedom of storage increases. In addition, this resin shelf board is easy to handle as a whole with heated hot water, hot air washing, and the like. Even if the weight is reduced, the strength is sufficient.

The inorganic antibacterial agent is entirely composed of an inorganic substance. Therefore, at a temperature of about 200 to 300 ° C., which is the molding temperature of the resin, the state hardly changes. Silver-based antibacterial agents such as silver thiosulfato complex and silver zeolite are used. This is because the antibacterial effect is higher and the safety is higher than copper-based antibacterial agents and zinc-based antibacterial agents. It is preferable that the silver-based antibacterial agent is mixed into the plastic at a temperature lower than 200 ° C.
