ABSTRACT:
A neck structure for a bottle-shaped container formed of synthetic resin, and associated with a rolled cap member having a top-closed cylindrical shape and constructed of thin aluminum plate at a cylindrical neck portion of the bottle-shaped container. The cylindrical neck portion has threads circumferentially formed on the outer periphery of the upper end of the cylindrical neck portion; at least one thick cylindrical portion of relatively large diameter is formed between the upper end of the cylindrical neck portion and the lower end of the cylindrical neck portion. The connecting portion is formed with a plurality of longitudinal strips on the outer periphery thereof and recesses between the longitudinal strips. The neck structure of the synthetic resin bottle-shaped container is constructed to be adapted to be associated with a tamper-proof-cap such that the lower end of the tamper-proof-cap is relatively increased in height.
