Title:
SYNTHETIC RESIN MULTILAYER BOTTLE
Document Type and Number:
WIPO Patent Application WO/2019/069794
Kind Code:
A1
Abstract:
Provided is a synthetic resin multilayer bottle in which it is possible to reliably prevent contents that comprise a liquid seasoning, including soy sauce, from degenerating due to oxygen, etc., in the outer air. The synthetic resin multilayer bottle 1 comprises an outer shell bottle 2 that is capable of returning to an original shape in response to deformation by pressure, an inner container body 3 that deforms due to pressure, and an air channel 23 that guides outer air between the outer shell bottle 2 and the inner container body 3. The synthetic resin multilayer bottle 1 comprises oxygen permeability properties such that, after the inner container body 3 has been completely filled with distilled water from which dissolved oxygen was removed, an inner opening 17 has been sealed, and the distilled water has been allowed to stand for 60 days at a temperature of 20°C while the air channel between the outer shell bottle and the inner container body was in an open state, the amount of dissolved oxygen in the distilled water is 3 ppm or less.
