BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a draining bag used for a kitchen sink or the like.

[0002]

2. Description of the Related Art Generally, the shape of a draining bag is shown in FIG.
A tubular sheet with one end sealed as shown in (a), a gusset-folded tubular sheet with one end sealed as shown in FIG. 8 (b), and two folds as shown in FIG. 8 (c) For example, there is a seal on both sides of the seat.

[0003]

In the above-mentioned and the above-mentioned and the above-mentioned and the other cases, when the kitchen garbage is put in, the bottom portion is not formed, and the capacity of the draining bag is small, and the drainage is poor. There is. In addition, in the case of, although the bottom is formed when the kitchen waste is put,
As shown in (b), the gusset shape has a drawback that three layers of sheet overlapping portions 11 are formed at the bottom, which results in poor drainage. Further, in order to solve these problems, a method of changing the material of the draining bag or a method of lowering the basis weight can be considered, but it is often difficult due to the influence of the strength reduction of the draining bag itself.

On the other hand, as described above, in order to eliminate the poor drainage of the kitchen draining bag, it is necessary to form a flat bottom portion in which the sheets do not overlap with each other when dust is put in. is necessary. However, the water-permeable effect of the material sheet itself cannot sufficiently exert the water-draining effect due to the flat bottom portion being formed and the surface area of the water-draining bag being expanded. As a result of various studies from such viewpoints, the present inventors have reached the conclusion that gusset folding is necessary and hole formation is further required to form the bottom when kitchen waste is put in, and the present invention is obtained. Has arrived.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1A and 1B are schematic views showing the drainage bag of the present embodiment. FIG. 1A is a plan view and FIG. 1B is a sectional view taken along the line AA ′ of FIG. FIG.
As shown in FIG. 3, the drainage bag 1 of the present embodiment has a free end 3a obtained by folding two nonwoven fabrics 2 made of a thermoplastic resin and combining them.
3b is the opening 4 of the draining bag 1 and is opposed to the free end 2
The folded end 5 is the bottom of the draining bag 1. Then, at the bottom of the drainage bag 1, the two-fold end portion 5 is gusset-folded inward to form a gusset fold portion 6 to form a Σ-shaped cross section.

At this time, the width of the portion of the gusset folding portion 6 which is folded back inward may be appropriately selected depending on the purpose of the drainage bag (a drainage basket for a sink, a triangular corner, etc.). Further, depending on the application, it may be a vertically long draining bag as in this embodiment, or may be a horizontally long draining bag.

Further, when the material sheet is folded in two, the free ends 3a and 3b do not necessarily need to be aligned as shown in FIG. 1, and as shown in FIG. The opening may be facilitated. In addition, the free end is cut straight as in this embodiment,
It can be formed in any shape, such as by forming it into an arbitrary shape or folding it back to a certain width.

Both sides of the material sheet 2 are heat-sealed, and heat-sealed portions 7a and 7b are formed to form a bag shape. At the gusset folding parts of the heat seals 7a, 7b, the gusset folding parts 6a, 6b, 6c,
Although 6d is heat-sealed as one sheet, the gusset folding parts 6a and 6b and the gusset folding parts 6c and 6d may be separately sealed. It is preferable to seal the both sides of the drainage bag by heat sealing, but other heat bonding, for example, hot melt sealing, fusing sealing, etc.,
Also, other known means may be used.

FIG. 3 is a perspective view from below when the kitchen waste 10 is put in the bag 1 of FIG. As described above, when the kitchen waste 10 is contained, the bottom portion 8 is formed in the draining bag 1 due to the gusset portion being expanded. Further, the non-woven fabric overlapping portions 9a and 9b formed by gusset folding are formed on the side portions of the bag. Therefore, the bottom 8 of the bag has no overlapping portion of the non-woven fabric and is continuous with the side surfaces 11a and 11b, so that water easily escapes from the kitchen waste 10 and the drainage property is extremely good.

The drainage bag having the above-mentioned configuration needs to be made of a material sheet having excellent water permeability, and therefore, in the present invention, it is used as a material sheet that has been subjected to perforation processing.

Although the material sheet is made of non-woven fabric in this embodiment, it may be made of film, net, split cloth or Japanese paper. The material of the material sheet is not particularly limited, and examples thereof include synthetic resin and pulp. From the viewpoint of sealing suitability, thermoplastic resins such as polyester, polyamide, polypropylene, and polyethylene are preferable. These may be used alone or in combination of two or more. Examples of the combination of two or more include a non-woven fabric composed of pulp and synthetic resin, a non-woven fabric composed of polyethylene-polypropylene composite fibers and polyester fibers.

When a nonwoven fabric is used as the material sheet, the single yarn fineness of the fibers forming the nonwoven fabric is preferably 20 de or less, and particularly preferably 3 to 15 de. Single yarn fineness is 20d
If it exceeds e, the gap between the fibers becomes large and the collection property for fine suspension becomes poor. Further, the basis weight of the non-woven fabric is preferably 15 g / m ² or more, particularly 15 to 25
g / m ² is preferred. If the basis weight is less than 15 g / m ² , the repairability for fine suspensions also deteriorates.

Among such nonwoven fabrics, the single yarn fineness is 1d.
A material having a weight of less than e or a weight per unit area of more than 60 g / m ² is usually a non-woven fabric that is dense and does not have good drainage, but can be made into a material sheet having good drainage by making a hole.

The non-woven fabric used in the present invention is preferably one that can be drilled by a spunlace method using a water jet or one that can be drilled by pin rolls, and that both sides of the draining bag can be sealed. Therefore, a dry non-woven fabric containing a composite fiber formed of a thermoplastic resin is particularly preferable.

When a film made of synthetic resin is used as the material sheet, the thickness of the film is preferably 8 to 100 μm, more preferably 14 to 40 μm. When the thickness of the film is less than 8 μm, the strength as a drainage bag is insufficient, while when it exceeds 100 μm, it is not preferable in terms of cost. The formation of the film may be appropriately selected depending on the synthetic resin used, such as the T-die method and the inflation molding method.

When a net or split cloth is used as the material sheet, it is preferably made of polyethylene.

The method of punching the material sheet may be appropriately selected depending on the type of the material sheet. For example, a method of punching using a pin roll, or a spunlace with water jet when the material sheet is a non-woven fabric. Law, etc.

In the spunlacing method using a water jet, for example, as shown in FIG. 4, an apparatus comprising a water jet head 20 and a water jet suction 21 is used to remove the nonwoven fabric 23 on the net pattern 22 from the water jet head 20. This is a method of drilling with a jet water jet ejected from the jet nozzle 24. As shown in FIG. 5, the non-woven fabric perforated by the spunlace method has fiber fluff around the periphery of the opening of the hole so as to close the hole, so that fine dust is also captured by the fluff. It is preferably used in the present invention.

The method for making holes using the pin rolls is not particularly limited, and it can be carried out according to a conventional method using the heated pin rolls 30 and the receiving rolls 31 (FIG. 6). The temperature of the pin roll is preferably in the range of its melting temperature when the material sheet is thermoplastic.

The size of the hole is preferably 1 mm or more in diameter, and particularly preferably 1.0 to 3.0 mm. If the size of the holes is less than 1 mm, clogging tends to occur when used as a drainage bag, resulting in poor drainage. In addition, the pitch of the holes is preferably 1.5 mm or more, and when the material sheet originally has water permeability, it is 3.0 to 10
mm is more preferable, and if it does not originally have water permeability, 2.0 to 10 mm is more preferable. If the pitch of the holes is less than 1.5 mm, the strength of the sheet itself is liable to be insufficient, and there is a possibility that the sheet may be easily broken when dust enters. In this example, holes having a diameter of 1.5 mm and a pitch of 3.0 m were provided by a spin-lace method using a water jet.

When using a pin roll for drilling, the entire material sheet may be drilled or only the portion corresponding to the lower portion of the draining bag may be drilled. FIG. 7 shows a draining bag made using such a material sheet. Further, the pitch of drilling does not necessarily have to be uniform and may be changed depending on the position. In this embodiment, the material sheet is punched and then folded, but the material sheet may be folded or further sealed and then punched. that's all,
Although the present invention has been described with reference to the embodiment, the present invention is not limited to this embodiment.

Test Example 1 Composite fiber of polyethylene and polypropylene (single yarn fineness 1
0 de) 60% by weight and recycled PET (polyethylene terephthalate) fiber (single yarn fineness 15 de) 40% by weight, a non-woven fabric having a basis weight of 20 g / m ² was perforated by a spunlace method using a water jet to have a diameter of 1.
Holes of 5 mm were formed with a pitch of 3.0 mm. This hole-punched nonwoven fabric is gusset-folded and both sides are heat-sealed, so that the outer dimensions are 120 mm × 115 mm in the opening,
A draining bag having a depth of 260 mm was formed. The water drainage bag thus obtained was subjected to the following water drainage effect test. Table 1 shows the results.

Test method for drainage effect Made of stainless steel having a height of 130 mm and a diameter of 111 mm,
The drain bag is inserted into the drain metal fitting consisting of the side mesh and the bottom punch plate, set in the drain outlet of the sink, and the rubber lid for the drain outlet is put on. Pour 200 cc of boiling water into the miso soup (immediate powder product) and stir. Pour 200cc of boiling water into 10g of bancha. Sprinkle instant ochazuke nori (1 bag) on 100g of rice and pour 200cc of boiling water. Pour boiling water into instant noodles (1 cup type). 1 bag of retort curry is diluted with boiled water to 500 cc. After 5 minutes, pour into the sink in the order of ~ (when flowing into the sink, make sure that the dust flows evenly from the entire circumference of the drain port). After 5 minutes, pour 10 liters of water at once into the sink to even out the trash. The time required for the water to flow out (the time when there is no water in the sink) is measured as the filtration time.

Comparative Test Examples 1 and 2 Other than the conventional drainage bag shown in FIG. 8A (Comparative Test Example 1) and the same shape as the same (Comparative Test Example 2) shown in FIG. 8C. In the same manner as in the above-mentioned test example, a draining bag was prepared using a non-woven fabric of the same material that was perforated, and a drainage effect test was conducted. Table 1 shows the results.

EFFECT OF THE INVENTION Since the kitchen drainer bag of the present invention is constructed by sealing the side of the bag having the gusset fold formed on the bottom of the punched material sheet, the gusset portion of the bag bottom is gusseted. It is easy to use and spreads easily, and it is also easy to insert into wide-mouthed items such as draining baskets and triangular corners of the kitchen drain. Further, since the bottom of the bag has no seal portion, the bag is not damaged by the weight of dust containing water. Furthermore, since the bottom area of the bag is increased by expanding the gusset portion, it is easy to remove water from the dust,
Very good drainage due to the holes formed on the side and bottom of the sheet. Therefore, according to the present invention, the water drainage from the bottom of the water draining bag is remarkably superior to the conventional product, and the water draining property of the entire water draining bag is significantly improved.
