<P>PROBLEM TO BE SOLVED: To provide a liquid mixture injection appliance capable of preventing the detention of air in its inside. <P>SOLUTION: A mixture injection appliance body 10 of this liquid mixture injection appliance A consists of a chamber part 11, and a downstream branch tube 12, an upper branch tube 13 and an upstream branch tube 14 extending from the chamber part 11 in different directions respectively. The upper branch tube 13 is attached with a rubber plug 20 with a slit 23 to close the upper branch tube 13, and a male lure portion 28a is inserted into the slit 23 to communicate the interior of the chamber part 11 with the male lure portion 28a. The rubber plug 20 consists of a fixed piece 22 fixed to an opening part side of the upper branch tube 13, and a rubber plug body 21 connected to the fixed piece 22 and being pushed in the inside of the upper branch tube 13 by inserting the male lure portion 28a into the slit 23. The rubber plug is so constituted that, when the rubber plug body 21 is pushed in the inside of the upper branch tube 13, the lower face of the rubber plug body 21 becomes an approximately horizontal face. <P>COPYRIGHT: (C)2008,JPO&INPIT |
