Abstract
A container comprises a first tubular body, a second tubular body disposed in the first tubular body, and a tubular cap slidably engaged with the first tubular body. The second tubular body has a chamber for containing a liquid and a neck portion protruding from the first tubular body. The neck portion has a surface at an end thereof puncturable to provide a discharge opening. The tubular cap has a first end, a second end, and a needle pin disposed inside of the tubular cap and mounted on an inner wall of the tubular cap at the first end thereof. The tubular cap is slidable on the first tubular body between a first position in which the needle pin is spaced from the surface of the neck portion of the second tubular body, and a second position in which the needle pin punctures the surface of the neck portion to provide the discharge opening. A first air-tight seal maintains the interior of the tubular cap in a hermetically sealed state when the tubular cap is in the first position. A second air-tight seal maintains the interior of the tubular cap in a hermetically sealed state when the tubular cap is in the second position.
