  • Patent number: 11459167
    Abstract: A pouch container generating hydrogen water is provided. A beverage containing at least water and a hydrogen generating substance that reacts with water to generate hydrogen gas are contained in a pouch container that is sealed. Even when hydrogen in a gas form leaks from a sealed part or the like of the pouch container to the outside, new hydrogen gas is generated by the reaction of the water and the hydrogen generating substance in the pouch container. Hydrogen water having sufficient hydrogen gas dissolved therein can be provided even after the long-term preservation. For example, the hydrogen generating substance may be contained in a straw or may be kneaded into an exterior sheet material.

  • Patent number: 10765603
    Abstract: A hydrogen-generating substance that reacts with moisture (liquid water or water vapor) in a medical substance or moisture in air introduced into a medical container is kneaded into an exterior sheet 40 of the medical container that encloses the medical substance therein. The medical container can be a bag-shaped medical container, a tube-shaped medical container, a medical container with a sealing fastener or the like. The medical substance containing moisture can be blood, an injection solution, a drug solution, a nutrient solution, a replenishment solution (an infusion solution), an instillation solution or the like. A solid preparation is preferably enclosed within the medical container with the sealing fastener. For example, the hydrogen-generating substance to be kneaded can be metal magnesium and is preferably fine-powdered ceramics obtained by firing the mixture of a hydrogen-generating substance and a mineral substance such as calcium.
