Summary of the Invention
Problems to be Solved by the Invention
[0005] For toilet fresheners, spray types cannot be carried onto an aircraft, and for granular types, even when placed in a case or the like, the smell may sometimes leak.
Means for Solving the Problems
[0006] The present invention aims to provide a structure that can be carried and can be flowed into a toilet or the like after use by wrapping a seamless capsule containing a fragrance made of gelatin or the like with a packaging material made of water-soluble paper.
[0007] By crushing the capsule inside the structure by hand, the oil is released and can be used as an air freshener. The packaging material dissolves in water, allowing it to be disposed of in a toilet or other suitable location afterward. [Effects of the Invention]
[0008] By forming a bag out of a single sheet of dissolvable paper with glue and placing an oil-filled seamless capsule inside, the structure prevents odor leakage, allows for easy diffusion of fragrance, and is simple to dispose of after use. [Brief explanation of the drawing]
[0009] [Figure 1] Unfolded diagram of the structure [Figure 2] Components in the process of assembly [Figure 3] Actual configuration during use [Modes for carrying out the invention]
[0010] Hereinafter, embodiments of this invention will be described with reference to the drawings. Fold part 1 of the unfolded diagram in Figure 1 inward to form a bag for holding the seamless capsule.
[0011] Figure 2 shows the seamless capsule (3) placed in the bag portion, with the lid (2) placed over it and secured with adhesive (4).
[0012] Figure 3 shows how to hold the structure containing the capsule in your hand and crush the capsule containing the packaging material for use. [Examples]
[0013] The container, which contains an oil-filled capsule, can be simply crushed with your fingers to release its fragrance, and can then be disposed of in a toilet or other suitable location. [Industrial applicability]
[0014] It can be easily carried in environments where liquids such as those in aircraft cannot be brought in, or in environments sensitive to odors such as restaurants, and can be easily discarded after use.
[0015] Since this component is 100% made of paper products, it can be used with environmental consideration.

Claims
1. A component that can be disposed of directly in a toilet or other container after use.
2. The mechanism of a portable air freshener using seamless capsules and dissolvable paper.
3. An assembly method that uses dissolvable paper and glue to create an envelope-like shape.
