ABSTRACT:
A combination of a customized bottle and a closure. The bottle has a neck with an interior circumferential surface defining a throat with a longitudinal axis and having an end face, at least a portion of which is inclined with respect to an imaginary plane perpendicular to the longitudinal axis. The closure has a head and a cylindrical shank extending from the head and has a cross-sectional area less than that of the head and having a longitudinal axis extending through the shank and having a cross-sectional area which is less than that of the cross-sectional area of the throat in the neck of the bottle. The head has a surface facing toward the shank and has a portion thereof which is inclined with respect to an imaginary plane perpendicular to the longitudinal axis of the shank and which is complementary to the inclined surface on the face of the neck. O-ring seals are carried by the shank for forming a sealing engagement with respect to the outer surface of the shank and the interior surface of the neck and providing a frictional engagement which is greater than the force which can be applied by a human to the closure for removal of the same until at least a portion of said O-ring seals has cleared the inner surface of the neck to thereafter permit removal of the closure by a human hand pulling on the closure to complete opening of the bottle.
