ABSTRACT:
The present invention relates to an extremely useful air-tight cap for bottle, and more particularly an air-tight cap adapted for use in a so-called positioning container wherein a bottle of a non-circular cross section such as a polygonal or oval form is closed by a cap of a same cross section when it is brought to a determined positional relationship with respect to said bottle and capable of achieving tight closure of the cap in such determined position to maintain air tightness and to completely prevent the leak of the content by means of a structure capable of achieving maximum packing effect.
