<P>PROBLEM TO BE SOLVED: To provide a spout not allowing water to remain even when contents are sterilized by heating with a cap installed on a container with the spout and to be equipped with an adapter simply. <P>SOLUTION: A screw section having two screws 7, 8 different leads is formed on the outer periphery of the spout tube 4 of the spout 1 to be attached to a container 2. The screw section comprises a small diameter screw section having a diameter ϕ<SB>2</SB>located to the spout end side and a large diameter screw section having a diameter ϕ<SB>1</SB>located to the container side. An adaptor requiring a sealing performance and easy removal property is mounted in the section of the large lead, and a cap 11 requiring a high sealing performance is mounted on the screw section having the small lead. Thus, water is not allowed to remain even if the contents in the container 3 with the spout capped with the cap 11 is sterilized by heating. The adaptor is mounted on the spout 1 simply and quickly. Operability becomes excellent thereby. <P>COPYRIGHT: (C)2007,JPO&INPIT |
