ABSTRACT:
A combination of a bottle (1) and a closure (2) for containing a drink, having an improved sealability. The bottle (1) is produced by a blow-molding process with a resin comprised mainly of a polyethylene terephthalate, so that a bottle neck (3) is in a non-crystalline state while a bottle body (5) is given an improved heat durability by a bi-axial orientation followed by a heat treatment for relaxation. The closure (2) is made of a thermoplastic resin such a a polyolefin and provided with a top wall and a side wall having a thread (7) on the inner surface (9) thereof corresponding to a thread (4) on the outer surface (12) of the bottle neck (3). The closure (2) has an annular shoulder (10) on the inner surface (8) of the top wall thereof which is engageable with the upper surface (11) of the bottle neck (3) and with the outer surface (12) of the bottle neck (3) adjacent thereto and an annular rib (13) protruded downward from the top wall at a place inside of the shoulder (10) to be resiliently engageable with the inner surface (14) of the side wall of the bottle neck (3).
