  • Patent number: 8668923
    Abstract: Washing with conventional filmy soaps cannot bring about clean detergent effect because of the remaining sliminess due to the ingredient essential for forming soap into films. Further, when moisture adheres to conventional filmy compositions, the water-soluble polymer or other ingredients contained in the compositions dissolve in the moisture to cause the blocking of filmy compositions, which makes it impossible to take out the filmy compositions one by one. Detergent effect without sliminess and the antiblocking of filmy compositions can be attained by incorporating a granular component into a filmy composition containing a water-soluble polymer. The filmy compositions of the invention are used as filmy facial masks, whitening masks, sheet soap, cleansing sheets, sheet shampoos, sheet rinses, sheet bath additives, and so on.

  • Patent number: 7841488
    Abstract: A sheet member container from which sheet members housed in a stacked state can be taken out reliably and in which occurrence of a wrinkle in a next sheet member in a returning operation of a sheet feeder is reduced. The sheet member container includes a container body having a top face opening for containing stacked sheet members; a lid member for openably/closably closing with respect to a top face opening of the container body; and a sheet feeding mechanism provided for the lid member for feeding the sheet members one by one from the top via a slot formed in either one of the container body or the lid member. The sheet member container includes a mechanism for bending the sheet members housed in the container body in a direction orthogonal to a feeding direction of the sheet members.
