Title:
BLOW-MOULDED CONTAINER USED WITH OIL FILM FORMED ON INNER SURFACE
Document Type and Number:
WIPO Patent Application WO/2019/031171
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a blow-moulded container onto which an oil film can be formed without unevenness across the entire inner surface of the container by coating the inner surface with an oil-based liquid. The blow-moulded container thereby exhibits stable lubricity with respect to a contained substance, and is capable of effectively inhibiting the contained substance from adhering to the inside of the container and remaining as residue. The blow-moulded container has an inner surface (1a) made of an olefin resin, and is characterised in that said inner surface (1a) uses a medium-chain fatty acid triglyceride as a standard oil, and when 0.8μl of said standard oil, maintained at 23°C, is dropped, the oil droplet dispersion, defined by the length of the major axis of a dropped oil droplet, is no less than 5.0mm.
