Abstract

A container includes a main body having an outlet for supplying fluid from the main body and a sliding member movable in the outlet according to relative movement of a withdrawal member fitting the sliding member during the supply of fluid from the main body through the withdrawal member, thereby providing a simple detachable structure which does not leak.

a main body having an outlet for supplying fluid from said main body, said outlet having a slit through which said fluid is supplied; and

a sliding member movably disposed for sliding member movement in a direction within said outlet according to relative movement of said withdrawal member and having a portion into which said withdrawal member fits, said sliding member comprising a guiding member engaged with said slit for guiding the sliding member movement and closing said outlet, wherein said slit and said guiding member prevent said sliding member from separating from said main body and said fluid is supplied through a portion of said slit when said sliding member is moved by said withdrawal member.

2. A container according to claim 1, wherein said slit is provided in an inner wall of said outlet along the direction of the sliding member movement and said guiding member comprises a projection portion for closing said outlet and a protruding portion for guiding the sliding member movement.

3. A container according to claim 1, wherein a sliding resistance between said outlet of said main body and said sliding member is smaller than a fitting resistance between said sliding member and said withdrawl member.

4. A container according to claim 1, wherein said sliding member forms a fluid passage in said outlet for fluid flowing from said slit.
