DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an epoch-making preservative antibacterial box for storage which has antibacterial properties and is less likely to cause damage to various fresh foods such as stored fresh fish and fresh vegetables, and a foam molding method thereof. .

[0002]

2. Description of the Related Art Various fresh food products such as fresh fish, semi-dried fish products (for example, horse mackerel, etc.), fresh vegetables, etc. generally pass through the wholesale market from the place of production and are subdivided into retailers' hands. Cross The fresh food is the first to keep freshness
And when the freshness drops, the price falls sharply. Especially in the summer, it is perishable and gives off a bad odor, so be careful when handling it. Therefore, at present, in the case of transportation of fresh fish and semi-dried fish products, generally, a styrofoam insulation box is filled with ice, and the fresh fish and semi-dried fish products are stored therein and transported by ice-cooling. Also, fresh vegetables such as vegetables are stored in a styrofoam heat insulation box and transported due to their heat insulating properties and lightness and ease of handling.

However, particularly in the case of fresh fish and semi-dried fish products in summer, the ice melts with time and the spoilage bacteria propagate to produce a spoiled odor, which is a commercial value There was a problem that a large amount of damage would occur if the value of the item became 0 and unsold items occurred. This was a serious problem, especially for retailers. (A comparative example will be shown later.)

On the other hand, the styrene foam insulation box is mass-produced and is very low in price for its bulk. When transporting styrofoam insulation boxes, although they are lightweight, they are bulky and the loading quantity is volumetrically limited, the transportation cost is high and the transportation range is limited. However, if you look at the manufacturer of the styrofoam insulation box, it is a product with a low profit level.

[0005]

The problem to be solved by the present invention is as follows.
On the user side, by adding anti-bactericidal property, it is possible to maintain the freshness of stored fresh food products for a long period of time, and on the manufacturer side, by adding anti-bacterial property, It is to be able to increase and differentiate products.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below with reference to illustrated embodiments. In this embodiment, a box of the type using the lid (11)
With (A), the box body (1) and lid (11) both have an anti-sterilization layer (2)
The case of forming the lid will be described as an example, but of course, the lid (11)
There is also a type without. In the box (A) of the type using the lid (11), the anti-sterilization layer (2) is formed on both or one of the box body (1) and the lid (11). The box body (1) is a box-shaped member having an upper surface opening, and a foamed resin molded body is generally used in consideration of heat insulation, lightness, strength, and mass productivity. Of course, it is not limited to this, and it may be an ordinary resin box or a wooden box. In the case of a foamed resin molded product, it is manufactured by a known foam molding method.
The above points also apply to the molding of the lid (11). A protruding strip (5) is provided on the opening edge of the box body (1), and the lid (11)
A concave strip (12) into which the convex strip (5) is fitted is formed on the outer peripheral edge of the back surface of the. Inner surface of box body (1) and lid (11)
An anti-sterilization layer (2) is formed on the back surface (= inner peripheral surface) of. Of course, it is preferable to form the anti-sterilization layer (2) on the entire inner peripheral surface of the box body (1) and the entire back surface of the lid (11) in order to exert the anti-sterilizing effect. It is needless to say that it is not limited to forming it on the entire back surface, and it may be a partial surface, only the inner peripheral surface of the box body (1) or the lid (1
Only the back side of 1) may be used.

The method for forming the anti-bactericidal layer (2) is not particularly limited, but as a first example, the inner peripheral surface of the box body (1) and / or the lid (11) can be mentioned. When the adhesive is applied to the back surface of the adhesive and the mixed powder of the anti-bactericidal powder and the far-infrared ray generating powder is sprinkled on the surface of the adhesive to form the anti-bacterial layer (2), the second example is・ Film for sterilization
When (3) is attached to the inner peripheral surface of the box body (1) and / or the back surface of the lid (11), as a third example, the inside of the box body (1) and / or
Alternatively, the case where the anti-sterilizing powder and the far-infrared ray generating powder are mixed in the lid (11) can be cited.

Examples of the anti-bactericidal powder include shell powder (a powder of shell as it is) and calcined shell powder (a shell of which is heated and calcined and then processed into powder). The shell powder and shell fired powder are not artificial and are processed in nature, so they are harmless when eaten, and are effective when used as an anti-bactericidal powder. The shell used is not particularly limited,
Oyster shells are preferred. The particle size is, for example, about 200 mesh and is a white fine powder. Needless to say, the particle size may be coarser or smaller than this. The composition of the powder is such that calcium is about 60% (50 to 70%) as a main component, and magnesium (400 to 600 mmg / 100 g), iron (40 to 60 mmg / 100 g), phosphorus (10 to 30 m).
mg / 100g), potassium (3 to 15 mmg / 100)
It contains minerals such as g). As a medicinal effect, it is effective in suppressing the growth or sterilization of various food-poisoning bacteria such as Bacillus, Staphylococcus aureus, Escherichia coli, and Salmonella typhi, and spoilage bacteria, as well as various molds such as yeast, black mold, red mold, blue mold and black mold.

Carbon powder, especially seaweed charcoal, is a good example of the far infrared ray generating powder. The raw material of the seaweed charcoal is not particularly specified, but may be any of postal algae, green algae, red algae, for example, seaweed, alame, kelp, hondawara, ascofilm, hijiki, tsunomata, giraffe, and resonia. And these dried products (water content 3-5%) are used.

As a method for producing seaweed charcoal, for example, the above seaweed is calcined at 400 to 600 ° C. for 2 to 6 hours to form an ash, and the ash is extracted with PH 5 to 14 to remove the separated residue. Use it as it is or bake it so that the whiteness of the hunter is 30 or more. This baked product is pure white seaweed.

Examples of the water extraction solvent include deionized water, distilled water, tap water, acidic water such as organic acid or inorganic acid, and other aqueous solvents. Further, the amount of water extraction solvent is not particularly limited, but is, for example, 4 to 2 per 1 part of ash.
0 parts.

As the extraction method, a commonly used dipping method is adopted, and the extraction is performed at 10 to 40 ° C. for 1 to 24 hours with stirring. As the extraction progresses, the extract becomes more alkaline due to its mineral component, but the pH of the extract is adjusted to 5 to 14, preferably 5 to 8 while adjusting the pH by adding an organic acid, an inorganic acid or the like. Set to the range and extract. This is because minerals such as Ca, Mg, Fe and Zn are excessively extracted when PH is less than 5.

A known method such as filtration or centrifugation is adopted for separating the extract and the residue. Then, the obtained residue is dried and pulverized into powder. The powder is
If the particle size is about 200 mesh, the surface area becomes sufficiently large to efficiently radiate far infrared rays, which is preferable. The powder also has a function as a far-infrared radiator, but the residue is re-reacted again.
A material having a higher emissivity for far-infrared rays can be obtained by blackening by heating again at about 00 to 600 ° C, preferably about 580 ° C.

The reason why seaweed is particularly effective as a far-infrared radiator is that many kinds of elements are taken in from seawater, and due to the variety of kinds of such elements, a relatively wide wavelength range and a low temperature of 40 ° C. or lower are used. This is because it is possible to obtain high emissivity and radiant intensity in the state.

Far infrared rays generally have a wavelength range of 4.0 to 1.
It is 000 μm, and its photon energy is smaller than that of near-infrared rays, but its penetrating power is strong, so radiant heat (radiant heat) can efficiently heat the inside of the object to be heated without unnecessarily increasing the surface temperature. is there. Especially in the wavelength range 8-12
Far-infrared rays of about μm penetrate well into moisture and exert their effect. In addition, as a secondary effect of far-infrared rays, the flavor of food is improved (disappearance of fishy odor and sweetness of fruit, etc.).
It also has antibacterial properties as described above.

Explaining the shell powder and the seaweed carbon powder used for the antibacterial layer (2), the shell powder and the seaweed carbon powder have an optimum weight ratio of about 1: 1 (usable range 1: 0.7-).
The mixture is uniformly mixed in 1.3), kneaded with 30% by weight of the mixture (usable range 15 to 45% by weight) of water, and then fired again to be powdered for use. As the method of use, as described above, there are surface spraying, film mixing, and box resin mixing. Anti-bacterial film
In the case of using (3), one example thereof will be briefly described. Extrusion molding is carried out by mixing a proper amount of a mixture of anti-bactericidal powder, which is a medicinal component, and far-infrared ray generating powder into a film substrate for inflation molding. While extruding in a cylinder from the tip while heating and kneading with a machine, blow hot air from the periphery to near the frost line of the cylindrical extrudate to heat it, expand it while heating and greatly expand its diameter, and finally The side is cut along the bus bar to form a film, which is wound up.

(3) is stretched between the foam molding male and female molds (9) and (10) as shown in FIG. 4, and the movable mold (9) is closed from this state as shown in FIG. Depressurize the inside of the mold (9) and extend the film (3) along the convex surface (9a) of the mold cavity (6) to make it convex.
Be in close contact with (9a). It is preferable to preheat the film (3) so that it can be easily stretched. Continuing with FIG.
Gun (7) the pre-expanded granules (8) into the mold cavity (6) as
Then, high temperature steam is introduced into both molds (9) and (10) to further foam the pre-expanded granules (8) to bond them to each other, and finally to cool them from the molds (9) and (10). Take out and cut off unnecessary parts of the film (3) to make the anti-sterilization heat insulating box body (1). The lid (11) is also manufactured by the same method,
The antibacterial film (3) will be attached to the back side.

Further, anti-bactericidal powder and far-infrared ray-generating powder are mixed in expanded beads, and the mixed beads are pre-expanded, and the pre-expanded beads are used to internally form the anti-sterilizing powder and far-infrared ray-generating powder. Box body containing and
The (1) and the lid (11) are molded by a known foam molding method. In this case, one of the foam particles that make up the box body (1) and lid (11)
The anti-bactericidal powder and the far-infrared ray-generating powder are distributed one by one to exert the anti-bactericidal action.

In the case described above, the box body (1) and lid (11)
The case where the foam molding was performed using the foam beads containing the anti-sterilization powder and the far-infrared ray-generating powder was explained, but the box body (1) was formed using the normal foam beads as shown in FIG. Then, the member (1a) to be the anti-sterilization layer (2) is foam-molded with anti-sterilization powder or far-infrared generating powder-containing foam beads,
It is also possible to fit this member (1a) into the box body (1). In both cases, the locking projections (1b) on the side surface of the member (1a) are fitted and fixed in the locking holes (1c) on the inner surface of the box body (1). This also applies to the lid (11), the lid body (11a) is foam-molded with ordinary foam beads, and the member (11a) to be the anti-sterilization layer (2) is used as anti-sterilization powder or far infrared rays. The foamed beads containing the generated powder are foam-molded, and the member (11a) is fixed to the back surface of the lid body (11a).

FIG. 2 shows another embodiment of the box body (1).
There are multiple vertical grooves (13) on the inner surface of the partition plate.
(4) can be fitted. An anti-sterilization layer (2) is formed on the outer peripheral surface of the partition plate (4). The method for forming the antibacterial / sterilizing layer (2) may be a coating method, a film sticking method, a mixed bead method or the like, as in the case of the box body (1). As a result, the inside of the box body (1) is subdivided into multiple rooms and stored in each room, so the position of the anti-sterilization layer (2) is closer to the stored items, and the anti-sterilization effect is Is improved.

<Experimental Example 1> A freshness preservation test was carried out using fresh horse mackerel flounder. Used anti-sterilization box (A)
Is a partition plate (4), which is used to resist and sterilize the entire inner surface of one room partitioned by the partition plate (4) (the inner surface of the box body (1) and one surface of the partition plate (4)). A layer (2) is formed, and the anti-sterilization layer (2) is not formed in the other rooms, both rooms are filled with ice, and the fresh horse mackerel is stored in it and the lid (1
1) was performed and the change was observed at appropriate times. An anti-sterilization layer (2) was formed on the back half (= anti-sterilization room side) of the lid (11), and no anti-sterilization layer (2) was formed on the rest. Therefore, the entire anti-sterilization room side is surrounded by the anti-sterilization layer (2), whereas the non-anti-sterilization room side does not have the anti-sterilization layer (2). << Table 1 >> Inspection part Anti-sterilization room side (invention) Non-anti-sterilization room side (Comparative example) Day 1 Fisheye transparent Same as left daytime Skin color Beautiful Same as left temperature Elasticity Abdominal stiffness Same left 30 ° C Freshness Product value 100 % Same as the left Fish meat Same as the left : Day 3 Fisheye Almost transparent Little cloudiness Daytime Skin color Little change Little change Temperature elasticity Little change Abdominal stiffness slightly softer 30 ° C Freshness Good product value Falling fish meat Firm still Firm : Day 7 Fisheye : slightly cloudy , slightly cloudy , daytime, skin color slightly changed, fins are shining, the entire body loses shine, cloudy temperature Elasticity slightly changes, abdomen softens, slumpy, 30 ° C, freshness, commercial value, commercial value: 0 fish The body is still firm and soft.
