[Problems to be solved by the device]

 For example, in the case of a container containing laundry detergent, it is frequently used as household daily goods, and it is troublesome to transfer it to another sealed container after opening. The external vibration may cause a part of the detergent to leak out and spread its scent, so that it may adhere to other articles around the place where the container is stored, and the scent is always good and undesirable. There was a point, and I had to solve it. In addition, the scent diffuses when the product is displayed at the store before it is opened and when it is stored and stored at home. The causes are: (a) Leakage of scent from the through holes for the tacks that are drilled to attach the proximal end of the handle to the container, (b) defective sticking flap, and (c) the material of the container body. Insufficient barrier resistance. In addition, looking at the more compact size of the above-mentioned detergent container, I have attached both ends of the handle to the upper side of the body to make it convenient to carry. Holes need to be drilled in the body for attachment, and similar points to the above remain to be solved. In addition, since the manufacturing facilities of the above are large in size, there is a problem with printability, and a special printing method is required, it is impossible to manufacture the final container at low cost as compared with the above. It is believed that. The present invention is to solve the problems inherent in the above-mentioned conventional technology, and the purpose thereof is to prevent the leakage of powdery contained objects and the dissipation of fragrance, thereby improving the manufacturing efficiency and manufacturing. The aim is to propose a powder packaging container that is economical in cost and convenient in use.
