(Field of Industrial Application) The present invention relates to a liquid paper container containing liquid beverages such as alcoholic beverages and youth. (Prior Art) In recent years, many liquid paper containers having a spout plug such as a plastic spout attached to the opening have been put into practical use as disposable packages for alcoholic beverages, juices, milk drinks, and the like. Under these current circumstances, even if a spout plug is attached to the opening to protect the contents, the gas barrier properties may be incomplete, and sheet materials mainly made of aluminum foil to cover the spout may be used. is used. However, in order to extend the life cycle of the contents of wine, youth, etc., sulfite-based preservatives are sometimes used, and sulfur oxides (SO 2
etc.), which causes corrosion of the aluminum foil. Therefore, polyvinylidene chloride (hereinafter referred to as polyvinylidene
PVDC) coated nylon, polyethylene terephthalate (K-NY, K-, respectively)
PVDC such as K-NY and K-PET are used, especially when wine is used as the content.
There was a drawback that the coat part turned white. (Problems to be Solved by the Invention) The present invention was made to solve the above-mentioned problems, and provides a liquid paper container that has excellent gas barrier properties even when the content is alcoholic beverages, especially wine. It is something. (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention seals the opening of the container body with a sealing member, and
A liquid paper container equipped with a spout stopper such as a plastic spout stopper, characterized in that the sealing member is formed of a sheet with a laminated structure mainly consisting of a plastic film layer provided with a thin film layer of silicon oxide. It is something. (Function) According to the present invention, even if sulfur oxide (SO 2 etc.) is generated, the thin film layer of silicon oxide will not corrode like aluminum foil, or the coated part like K-NY and K-PET will corrode. will not turn white. (Example) To explain the present invention in detail using drawings, the first
The figure is an explanatory cross-sectional view of essential parts showing an embodiment of the present invention, and shows a spout plug B, which is formed by capping an opening A1 of a container body A with a screw-type cap 2 on a plastic spout body 1. This is a liquid paper container S containing wine, and a thin film layer 11 of silicon oxide of 200 to 700 mm is provided from the inside of the opening A1 .
This is a liquid container made by adhering a sealing member C made of a polyethylene adhesive layer 13 laminated to a 12μ thick PET film 12. Here, in the above embodiment, the PET film 12
For example, a polyethylene film may be used instead. Next, the oxygen permeability of the following materials was measured to confirm their gas barrier properties, and the results are shown in Table 1. (1) Measurement material PET 12μ film coated with SiO600 used in this invention. ONY (biaxially oriented nylon) thickness 15μ. K-ONY (PVDC coated biaxially stretched nylon) thickness 15μ (PVDC thickness 3μ). PET12μ. K-PET (PVDC coated PET) 12μ
(PVDC thickness 3μ). A foil 9μ thick. PET 12μ film with A evaporation 600〓.
