Resin composition and use of same
A resin composition comprises: a modified EVOH (A) that is represented by a following formula (I), has contents (mol %) of a, b, and c based on the total monomer units satisfying following formulae (1) through (3), and has a degree of saponification (DS) defined by a following formula (4) of 90 mol % or more; and inorganic oxide particles (B), wherein a content of the inorganic oxide particles (B) is from 5 to 5000 ppm. Such a resin composition is improved in adhesion to a resin other than EVOH, secondary processability, and flexibility without decreasing the performances originally possessed by EVOH, such as gas barrier properties, transparency, flavor retention, solvent resistance, and oil resistance. Accordingly, the resin is preferably used as a molded article, a film, a sheet, a heat shrinkable film, a thermoformed article, a multilayer structure, a coinjection stretch blow molded container, a fuel container, and the like. ##STR00001##

Three-dimensionally thermo-molded footwear
Articles of footwear including a thermo-molded upper having a skin composed of one or more low melting point thermoplastic polymers. The skin may include at least one of: a base layer composed of a low melting point thermoplastic polymer and a grid layer including a yarn composed of a low melting point thermoplastic polymer. The uppers may be formed by placing a skin and an inflatable bladder into a mold cavity and heating the mold to a predetermined temperature. The inflatable bladder may be inflated such that the skin is pressed against an interior surface of the heated mold cavity to cause the skin to take on the shape of the internal surface of the mold cavity, thereby forming an upper for an article of footwear.
Method for manufacturing dual cosmetic container
Discloses is a method for manufacturing a dual cosmetic container. The method includes: molding an inner preform 40 or 40a formed with a patterned portion having one or more shapes selected from characters, pictures, figures, and helical grooves on the outer surface thereof using an upper mold 10 for the inner preform having a molding space 11 and formed with a pattern molding portion 12a on the inner circumferential surface thereof and an lower mold 14 for the inner preform having a molding space 15 for a discharge portion; inserting the inner preform 40 or 40a into a molding space 21 of an upper mold 20 for an outer preform, fixing a discharge portion 41 of the inner preform 40 or 40a to a lower mold 23 for the outer preform, feeding a liquid raw material into the molding space 21 of the upper mold 20 for the outer preform, and molding the outer preform 50 in close contact with the outer surface of the inner preform 40 or 40a formed with the patterned portion 42; and simultaneously heating the inner preform 40 or 40a and the outer preform 50 molded in close contact with each other, inserting the two heated preforms into a molding space 31 of a blow mold 30, inserting a blow tube 32 into the discharge portion 41 of the inner preform 40 or 40a, and simultaneously expanding the inner preform 40 or 40a and the outer preform 50 by blow molding to manufacture the desired dual cosmetic container in which an inner container 100 or 100a and an outer container 200 are in close contact with each other.
