  • Ink composition for sensing carbon dioxide gas, carbon dioxide indicator using the same, package provided with the carbon dioxide indicator, and method for sensing pinhole using the same
    Publication number: 20100224508
    Abstract: An ink composition for sensing carbon dioxide gas contains a pH indicator formed using a combination of two or more types of pH indicator components, binder, and solvent and allows easy visual observation of color changes of an indicating portion caused by the concentration of carbon dioxide gas. When the ink composition is applied to a carbon dioxide indicator and package, a pinhole and poor seal of a carbon-dioxide-ambient package are easily found.

  • Medical multi-chamber container
    Patent number: 7658279
    Abstract: A medical multi-chamber container (1) comprising a container body (3) having first and second chambers (10, 11) for storing medicaments, a weak partition seal (20) for portioning the charmers (10, 11) from each other, and an outlet (32) fitted into the container body (3) for allowing the medicaments to be delivered from the second chamber (11), the container body (3) further comprising a weak discharge seal (21) partitioning the second chamber (11) from the outlet (32) and unsealably formed so as to allow the chambers (10, 11) to communicate with each other when used, characterized in that the unsealing strength of the weak discharge seal (21) is less than that of the weak partition seal (20).

  • Ink composition for sensing carbon dioxide gas, and carbon dioxide indicator using the same, and package provided with the carbon dioxide indicator
    Publication number: 20030045608
    Abstract: An ink composition for sensing carbon dioxide gas contains a pH indicator, binder, and solvent and allows easy visual observation of color changes of an indicating portion caused by the concentration of carbon dioxide gas. When this ink composition is applied to a carbon dioxide indicator and package, a pinhole and poor seal of a gas-replaced package sealing a replacement gas which contains carbon dioxide gas are easily found.
