  • Patent number: 5934457
    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.

  • Patent number: 4056109
    Abstract: A hair-curler of the non-electrothermal type comprising a cage-like tubular core formed at its one end with at least two slots intersecting each other at the center of the end, a hollow cylindrical cover of cellular synthetic resin covering the tubular core, a frame support fitted in the other end of the tubular core and rotatable relative to the tubular core, and a rectangular holding frame having one end pivoted to the support and the other end provided with an engaging projection detachably engageable in one of the slots so that the hair is wound onto the cover while rotating the tubular core relative to the holding frame and is then held to the cover with the holding frame by engaging the projection in the slot. The hair can be readily effectively held in place by the holding frame in the desired angularly displaced position of the tubular core without using a separate hairpin for holding the hair.
