Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laundry product containing packaged laundry articles.

[0002]

2. Description of the Related Art There is known a one-pack detergent in which a single washing detergent is packaged and packaged with a water-soluble film or the like in consideration of consumer convenience (Japanese Patent Application Laid-Open No. 63-12467).

[0003] From the viewpoints of ease of use, low price, ease of production and molding, and printability, the powdery and granular detergents are generally used in a box-shaped container made of processed paper. The place where it is used and stored has a relatively high humidity, and a container made of processed paper absorbs moisture. Since the granular detergent is in direct contact with the inner wall of the container, an alkali agent or the like in the detergent suppresses the generation of molds and bacteria on the inner wall of the container, thereby suppressing the generation of an unpleasant odor. However, when the package is stored in a container, the detergent does not come into direct contact with the inner wall of the container.

[0004] Further, polyvinyl alcohol-based packaging materials which are preferably used as packaging materials for divided packaging detergents have extremely low gas permeability, so that components in the enclosed detergent composition, especially fragrances, are emitted. This is characterized by the fact that the flavor of the detergent composition that has passed through the polyvinyl alcohol-based packaging material and contained therein is less likely to smell. For this reason, there has been a problem that the generated off-flavor cannot be masked.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to suppress the generation of an unusual odor due to molds, fungi and the like in a container.
