である。In order to overcome this drawback, it is known to use a water-permeable sheet such as a non-woven fabric as the material for the container (Japanese Patent Application Laid-open No. 142410/1982), and a thermal adhesive is used instead of a water-soluble adhesive. It is known that the bag is designed so that a water-soluble adhesive having the following properties is applied in advance and dried, and then the bag is closed by heat sealing when storing detergent.
-39640, JP-A-62-287861). These individual packaged detergents are particularly useful with the spread of fully automatic washing machines. That is, in a fully automatic washing machine, laundry and detergent are first loaded. Then, when the washing process begins, water is forced in for the first time, and the detergent dissolves in the water.However, since the water is poured in gradually afterwards, if powdered detergent is added directly, it will not dissolve completely. This is because there is a problem in that unused detergent becomes lumps and adheres to a part of the clothes.

としても十分なシールができないという問題が生した。<Problems to be Solved by the Invention> However, using the above-mentioned technology, a water-soluble adhesive is applied to a water-permeable sheet and dried to form a bag.
If you try to store detergent, the water-permeable sheet is relatively porous, so even if you apply a water-soluble adhesive, the water-soluble adhesive will seep into the sheet, making it difficult to close the bag. A problem arose in that sufficient sealing could not be achieved.
また、上記水浸透性シートは印刷適性が悪く、商品とし

The permeable sheet and the other packaging material form an adhesive dissolving layer made of a water-soluble adhesive having thermal adhesive properties, or a water-dissolving layer and a thermoadhesive resin layer in this order, on at least the intended opening portion of the plastic film. It consists of an impermeable sheet with an adhesive dissolving layer.
Both sheets are heat-sealed via the adhesive dissolving layer,
It is an individually packaged detergent. In addition, the above-described adhesive dissolving layer is formed on at least the area where the opening is planned on the plastic film, the water-permeable sheet is layered to seal the periphery leaving an opening, and then a predetermined amount of powdered detergent is applied to the opening. This is a method for producing an individual packaged detergent, characterized in that the opening is sealed after filling the detergent.

のである。The embodiment shown in Fig. 1 consists of a water-permeable sheet (1) and an impermeable sheet (2), and the impermeable sheet (2) is a water-soluble adhesive that has thermal adhesion properties to a plastic film (21). An adhesive dissolving layer (22) is formed by applying an adhesive and drying it.

だけ大きな目の不織布を用いることが好ましい。なお、
耐水性のない紙等は、使用時に洗濯機中で分解・分散し
てしまい、洗濯物を汚染してしまうので好ましくない。The water-permeable sheet (1) can be a water-insoluble sheet such as a non-woven fabric or a perforated plastic film. It is preferable to use a nonwoven fabric with a mesh that is finer than the average particle diameter of (4) and as large as possible. In addition,
Paper or the like that is not water resistant is undesirable because it decomposes and disperses in the washing machine during use, contaminating the laundry.
この点からすれば、不織布は短繊維のものでなく、長繊
維のものが好ましい。From this point of view, it is preferable that the nonwoven fabric be made of long fibers rather than short fibers.

まうので水の浸透性が不十分である。Since the nonwoven fabric must be permeable to water, it is preferably hydrophilic. Specifically, cellulose-based nonwoven fabrics, polyvinyl alcohol-based nonwoven fabrics, etc. are preferable.
For example, hemp fibers coated with viscose can be used. On the other hand, hydrophobic nonwoven fabrics such as polyolefin nonwoven fabrics and polyester nonwoven fabrics repel water and therefore have insufficient water permeability.

である。The water-soluble adhesive of the adhesive dissolving layer (22) has thermal adhesive properties and has the property of dissolving (including decomposition and dispersion) in water, and is a seal that can sufficiently seal the bag. It is strong and dissolves quickly when washed. The sealing strength is preferably 150g/15m-width or more in T-peel, and the water solubility is 150g/15m-width or more under actual washing conditions.
Specific examples of water-soluble adhesives that can be used as water-soluble adhesives that are preferably such that the bag can be opened within minutes, more preferably within 15 seconds are disclosed in the aforementioned Japanese Patent Publication No. 63-39640 and Japanese Patent Application Laid-Open No. 62-1999. As shown in Japanese Patent No. 287861, for example, polyvinyl alcohol resin alone, polyvinyl alcohol resin, polyvinyl pyrrolidone resin,
Examples include mixtures of pre-water-soluble components such as dextrin and heat-adhesive components such as polyvinyl acetate, ethylene-vinyl acetate copolymers, and polyacrylic esters. In particular, the material disclosed in JP-A-62287861 is a preferred material because the sealing strength and water solubility can be changed by changing the types and mixing ratio of both components.

Approximately 20 g/rrr is good; for example, when using a mixture of polyvinyl alcohol and ethylene-hinyl acetate copolymer at a ratio of 35:65, it is 10 to 15 g/rrf.
Good heat sealability and opening properties can be obtained by applying . In addition, when opening only a part of the bag, the adhesive dissolving layer (
22) may be provided only in the intended opening portion (3); in this case, a suitable adhesive or the like is applied to the other sealing portions to enable sealing.
第２図は本発明の他の実施例を示す断面図である。この
実施例は、接着溶解層（２２）が若干具なるほかは、第
１の実施例とほぼ同様である。FIG. 2 is a sectional view showing another embodiment of the present invention. This embodiment is substantially the same as the first embodiment, except that it includes a slight adhesive dissolving layer (22).
接着溶解層（２２）は、水溶解層（２２１） 、熱接着

ばよく、別々にコートすることに利点がある。For the water-soluble layer (221) and the heat-adhesive resin layer (222), the pre-water-soluble component and heat-adhesive component of the water-soluble adhesive used in the first embodiment can be used, respectively. In the case of this embodiment, since the water-soluble layer (221) and the heat-adhesive resin layer (222) are coated separately, there is an advantage that each coating agent and coating work can be easily managed. In addition, if you want to open only a part of the water-dissolved layer (
221) is applied to the part to be opened, and the thermoadhesive resin layer (222) is applied to the entire part to be sealed; there is an advantage in coating them separately.

すれば問題がない。The water-soluble layer (221) is a plastic film (21)
The thermoadhesive resin layer (222) may be formed as a film on top of the plastic film (21) to a thickness that does not directly contact the plastic film (21), and may be coated at 2 to 10 g/rrf. (222) is preferably provided at 3 g/rd or more in order to have sufficient adhesive strength. Furthermore, during use, water must enter from the water-permeable sheet (1) and reach the water-soluble layer (221). Therefore, the thermoadhesive resin layer (222) must be provided in a state that allows water to pass through.

ものと考えられる。To use the individual packaged detergent of the present invention, it is only necessary to put the individual packaged detergent into the washing machine together with the clothes, and when water is injected, the water permeates through the water-permeable sheet and dissolves the water-soluble adhesive. The bag then opens and the detergent is released. Note that the opening of the bag and the release of detergent are facilitated by agitation by a washing machine. In other words, if water is simply injected, the adhesive will dissolve, but the bag will be difficult to open completely, and the bag will be able to be opened.
It is thought that it is completely opened and released by receiving the movement of water.

きわめて有用なものである。<Effects of the Invention> Since the individual packaged detergent according to the present invention has the above-described structure, when it is put into the washing machine together with the laundry, it automatically opens and the detergent is released during washing, making it easy to use. It's good. The adhesive dissolving layer is applied to the plastic film in advance and dried, and is formed in a sufficient amount and can be sealed by heat sealing.
There is no problem of adhesive penetration and poor sealing as in the past, and industrial manufacturing is possible, and sufficient sealing performance can be obtained. In addition, during use, water quickly penetrates and reaches the entire seal part from the water-permeable sheet, and the adhesive dissolving layer quickly dissolves, allowing the detergent to be released immediately and leaving no residue after dissolving the detergent. Above all, it is extremely useful.
