There is provided a bottle formed of a synthetic resin material into a cylindrical shape with a bottom, a bottom wall portion of the bottom includes: a ground contact portion which is positioned at an outer circumferential edge portion; a rising peripheral wall portion which is connected to the ground contact portion from an inner side of a bottle radial direction and extends upward; an annular movable wall portion which protrudes from an upper end portion of the rising peripheral wall portion to the inner side of the bottle radial direction; and a depressed peripheral wall portion which extends upward from an inner end portion of the movable wall portion in the bottle radial direction.

A porous silica which can be formed into various shapes excellent transparency, capable to be nanoparticulated, capable to be obtained at a high efficiency even when a cationic surfactant having 7 or less carbon atoms is used. Alkoxysilane is dispersed with a cationic surfactant in which a hydrophobic moiety has 2 to 7 of carbon atoms, and added water of which pH is adjusted to 0-2 with the amount of 2-4 equivalents to the alkoxysilane, and mildly hydrolyzed to obtain a monolithic mesoporous silica of which a pore diameter is not less than 0.5 nm and less than 2 nm. A pore diameter can be controlled by adding an organic silane to the system. By adding polyethylene glycol to the synthesis system, a monolithic mesoporous silica nanoparticle is obtained.

The bottle is provided with a base portion installed on the outer circumference brim of the bottom, a central recess installed inside the base portion and recessed toward the inside of the bottle, an annular wall portion installed between the base portion and the central recess and inclined so as to elevate gradually from the base portion to the central recess, and a plurality of ribs installed side by side at the annular wall portion in the circumferential direction of the bottom and protruding toward the inside of the bottle. The ribs are provided with a rising wall portion rising toward the inside of the bottle and an inclined wall portion inclined from the upper brim of the rising wall portion toward the lower brim of the rising wall portion of an adjacent rib. The rising wall portion is inclined more steeply than the inclined wall portion.
摘要:
A method for preparing corneocytes specimen, which comprises stripping off corneocytes from the surface of a skin using an adhesive material, staining the corneocytes in a solution of stain in solvent containing a water-miscible organic solvent, and mounting the stained corneocytes into an oil and fat constituent and/or composition that is liquid at 1 atm, 25° C.
