Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainer bag used in a kitchen, a kitchen or the like (hereinafter simply referred to as a kitchen).

[0002]

2. Description of the Related Art Garbage generated in kitchens, such as food scraps, fish bones, vegetable scraps, cooking scraps, food packaging materials, coffee, green tea and tea leaves, cooking scraps such as fruit scraps, leftovers, and oil. BACKGROUND OF THE INVENTION Drainage bags are used to collect dust and the like, remove water by separating it to some extent, and discard the remaining solid matter as raw garbage.

Such a drainage bag is required to have a drainage property in order to filter only water to leave a solid substance, and a required strength to hold the weight of the solid substance. Conventionally, such drainage bags are generally made of non-woven fabric made of synthetic resin such as polypropylene, polyethylene, polyester, nylon, polyurethane or the like, a woven fabric or a net formed into a bag shape, a bag of synthetic resin film having a drainage hole, etc. ing.

[0004]

Among the above-mentioned water draining bags, the non-woven water draining bag has relatively good dust trapping property and drainage property, but has a small oil adsorption amount. This is because the basis weight cannot be increased so much because it is necessary to keep the drainage property moderate. Therefore, in conventional drainage bags, oil leaks out along with water and adheres to kitchen sinks and drains as oil stains, causing problems in hygiene and maintaining aesthetics, and in extreme cases, oil drains. There were problems such as accumulation inside the mouth and clogging of the drainage port.

The present invention has been made for the purpose of solving the above problems, and maintains proper drainage without increasing the basis weight, improves oil absorption, and improves hygiene and aesthetics in kitchens and the like. The purpose of the present invention is to provide a drainage bag that can be maintained and further prevent environmental pollution due to clogging of drainage ports and outflow of oil.

[0006]

The drainage bag of the present invention is characterized by using a composite non-woven fabric in which a non-woven fabric composed of continuous long fibers and a dry non-woven fabric composed of short fibers are partially or wholly laminated. According to the drainage bag of the present invention, the oil absorbency is significantly improved by the dry nonwoven fabric. Among the composite non-woven fabrics used for the drainage bag of the present invention, the non-woven fabric composed of continuous long fibers is a spunbonded non-woven fabric made of polyester resin, polyethylene, polyolefin resin such as polypropylene as a raw material, and among them, the heat of the dry non-woven fabric From the viewpoint of fusion processability, a spunbonded nonwoven fabric of polyolefin resin is preferable.

The polyolefin resin is preferably a polymer containing propylene as a main component, that is, a homopolymer of propylene, or a copolymer of propylene and another compound copolymerizable with the propylene. Other compounds copolymerizable with propylene include, for example, α such as ethylene, 1-butene, 1-pentene and 1-octene.
-Olefin, vinyl chloride, vinyl acetate, methacrylic acid esters, acrylic acid esters and the like may be mentioned, and these may be used alone or in combination of two or more in the polyolefin resin. Specific examples of the polyolefin resin include propylene / ethylene copolymers and propylene / 1-butene copolymers.

A nonwoven fabric made of continuous long fibers has a basis weight of 3
˜80 g / m ² , preferably 8 to 25 g / m ² , thickness of 0.1 to 20 mm, preferably 0.1 to 0.8 mm, fiber diameter of 5 to 50 μm, preferably 10 to 30 μm
It is a degree. On the other hand, as the dry non-woven fabric composed of short fibers, any fiber that can be carded, such as polyester fiber and polyolefin fiber, can be used.

The dry non-woven fabric has a basis weight of 5 to 80 g /
m ² , preferably about 8 to 25 g / m ² , with a thickness of 0.1
~ 20 mm, preferably about 0.1-3 mm, fiber diameter 5
50 μm, preferably 10 to 30 μm, fiber length 1
It is preferably about 0 to 100 mm, preferably about 20 to 75 mm, and a web formed as bulky as possible has high oil absorption and is desirable.

Heat-embossing is desirable for the attachment of continuous long-fiber non-woven fabric and dry non-woven fabric because of its high productivity,
In addition, processing methods generally used for bonding non-woven fabrics such as ultrasonic sealing and needle punching can be used. As shown in FIG. 2, as shown in FIG. 2, two sheets of a composite nonwoven fabric 7 in which a continuous long-fiber nonwoven fabric 1 and a dry nonwoven fabric 6 are bonded by heat embossing are stacked with the dry nonwoven fabric side inside, and a bottom edge 2 and both side edges are formed. It shows an example in which three sides 3 and 4 are heat-sealed to form a drainage bag 5.

The above-mentioned draining bag may be formed such that the dry non-woven fabric side is outside, or the dry non-woven fabric side and the long fiber non-woven fabric side are inside each other. In the present method, heat fusion can be performed by, for example, fusing seal using a heat cutter, pressure bonding using a high frequency welder, or the like. It is desirable that the drainage bag obtained as described above has hydrophilicity in order to maintain drainage and allow water to pass through smoothly, and also to prevent the put dust from decaying or causing mold to grow. It is desirable to have antibacterial and antifungal properties.

In order to make the drainage bag hydrophilic, a hydrophilic agent may be kneaded into the resin, but normally, for example, glycerin fatty acid ester, sorbitan fatty acid ester, polyethylene glycol fatty acid ester, polyoxypropylene, poly Using an aqueous solution in which a hydrophilic agent such as an oxyethylene block polymer is dissolved in water, a continuous long fiber nonwoven fabric and / or a dry nonwoven fabric or a composite nonwoven fabric is coated with, for example, a gravure roll coater.
In order to provide antibacterial and antifungal properties, the resin may be, for example, an imidazole 2- (4-thiazolyl) benzimidazole, or an inorganic antibacterial and antifungal agent such as zirconium phosphate carrying metallic silver. It is advisable to knead the agent or to coat the raw material with the solution in which the antibacterial and antifungal agent is dissolved as described above.

[Table 1]

Next, using the composite non-woven fabric prepared as described above, a folding diameter of 23.5 cm and a depth of 25 were obtained by heat sealing.
I made a cm drainer bag. Drainage was examined by injecting 500 cc of water into each of the bag obtained as described above and the bag obtained in the same manner using the above-mentioned product name Syntex PK-805. As a result, both drained within a few seconds.

Next, food was actually put in each of the above bags and a practical performance test was conducted. That is, when a commercially available retort curry bag was put in each of the above-mentioned bags as a food, water quickly escaped. When the liquid dripping from the bag is dropped into the basin containing water after the water has escaped, the liquid dripping from the bag made of the product name Syntex PK-805 mentioned above spreads widely on the water surface of the basin. Although the oil spreads, the liquid dripping from the bag made by the present invention has extremely little oil,
The oil was found to be well absorbed in the bag and retained in the bag.

[0019]

According to the drainage bag of the present invention, it is possible to improve the oil adsorbability without impairing the drainage property, and the oil adsorbability is superior to the conventional ones.
The oil that separates from the oil residue does not leak, the hygiene and aesthetics of the kitchen and the like are maintained, and the oil content can prevent clogging of the discharge port and environmental pollution.

Further, as a nonwoven fabric made of continuous long fibers,
If a spunbonded non-woven fabric of polyolefin resin is used, it has good heat fusion processability with dry non-woven fabric, and if continuous continuous fiber non-woven fabric and dry non-woven fabric are pasted together by heat embossing, productivity can be increased. . Furthermore, a water-repellent bag treated with hydrophilicity allows water to pass through smoothly, resulting in better drainage, and a drainer bag subjected to antibacterial and antifungal treatment prevents the put-in dust from decaying. , Mold grows bad.
