  • Patent number: 6641307
    Abstract: At least one branched chamber extends and diverges from a side wall of a pouch body. The branched chamber has an optional pouring spout at its distal end to permit the removal of the contents of the pouch. A readily unsealable seal member is optionally included to partition the branched chamber from the pouch body, thus providing a pouch wherein two or more different materials are mixed prior to removal from the pouch. A pouch having this structure provides excellent rupture protection of the readily unsealable seal member caused from, for example, handling, shipping, or dropping of the pouch.

  • Publication number: 20020058213
    Abstract: A silver halide photosensitive material in which a noncoloring compound is used as a high-boiling-point organic solvent for dissolving components of the silver halide photosensitive material that have low solubility in water. Preferably, the silver halide photosensitive material has a hydrophilic colloid layer containing a hydrophilic polymer and the noncoloring compound is contained in the hydrophilic colloid layer. The silver halide photosensitive material produces durable colored images, reduces the formation of stains, improves storability, alleviates fogging and soft-toning of emulsion during storage, inhibits migration of a dispersion medium, is inexpensive, and is produced from materials that cause little damage to the environment.
