Document Type and Number:
Japanese Patent JP3388781
Kind Code:
B2
Abstract:
PURPOSE: To enable drinking of a beverage after the time elapsing from packing or unsealing in the state of enhanced taste by molding the outer layer of a packaging container of a composite material formed by mixing a food perfume which enables the recognition of the beverage with a resin.
CONSTITUTION: An aluminum foil layer 5 forms a barrier for light and gas to the beverage housed in the packaging container 1 to prevent the deterioration in the properties of the beverage and the dissipation of the food perfume. Two adhesive resin layers 4 improve the adhesiveness between a paper material 3 and the aluminum foil layer 5 and the adhesiveness between the aluminum foil layer 5 and a polyethylene(PE) resin layer 6. On the other hand, the outer surface of the paper material 3 is coated with a perfume-contg. resin layer 7 to form the exterior surface. The composite material formed by mixing the food perfume which enables the recognition of the beverage with the PE resin is extrusion molded, by which the container is obtd. The amt. of the food perfume to be released is increased when the container is irradiated with light and is decreased when the container is not irradiated with the light if the container is molded of the composite material formed by mixing, for example, a photosensitive perfume-including material of a microcapsule material with the resin.
