ABSTRACT:
A bottle with a prealigned closure means comprising a bottle with a neck on the top thereof provided with a threading and a collar at the base thereof having stop shoulders, said shoulders each having an oblique side with an associated inclination angle, a capsule with a closed end provided with an interior threading adapted to engage the threading of the bottle neck, a hollow cap means with the capsule axially disposed therein and provided with means to immoveably secure the capsule with respect to the cap, the lower edge of the capsule being provided with two diametrically opposite grooves in the form of a right-angle triangle whose side opposite the smaller of the acute angles is parallel to the axis of the capsule, the said smaller acute angle determining the inclination of the oblique side of the said right-angled triangle, said smaller acute angle being greater than the inclination angle of the stop shoulders of the bottle with which the grooves are destined to cooperate.
