INJECTOR HAVING INJECTION DELAY MEMBER

摘要

PROBLEM TO BE SOLVED: To provide injector to delay the injection of contents in a container. SOLUTION: This equipment is provided with a barrel-shaped cylinder 2 which has a through port at the central recess of its bottom and has a locking pawl 2' at the outer periphery of its top edge; a piston 4 which is penetrated through the central small-diameter barrel part communicated by fluid with the through port of the cylinder is airtightly fitted into the cylinder; an injection delay member 7 having a microporous member 10 is fitted onto the piston; a cylinder cover 3 is disposed to be put on the piston from above; the cylinder cover is coupled to the cylinder, by which the space formed therebetween is made into the hermetic space when the through port of the cylinder is closed; this space is compartmentalized by the piston 4 to an upper chamber 13 and a lower chamber; a push button 5 is inserted into the central small-diameter barrel part of the piston 4 from above, by which the structure integral with the piston 4 is formed and a cap 1 is disposed around the cylinder in such a manner that the locking relation with the locking pawl is maintained.
