PURPOSE:To feed very small amount of liquid accurately without relying on the feeling by providing a cylinder section for containing liquid of intermediate/ high viscosity while having a needle-type delivery port and a circuit for feeding compressed air of uniform pressure continually into the cylinder section. CONSTITUTION:Predetermined amount of adhesive having intermediate/high viscosity is contained in the cylinder section 10 then a cover body 14 is fitted to the opening at the upper end of cylinder section and sealed thereafter projected to the lower end of cylinder section and sealed. Then a needle-type delivery port 12 projecting to the lower end of cylinder section is applied to the screw- lock section of the system to depress a push button switch 34 on the upper face of the cover body. Consequently, a timer 24 will function for predetermined time to feed the compressed air through a compressed air supply circuit 22 into the upper sction of cylinder section 10 while the liquid of intermediate/high viscosity in the lower section of cylinder section 10 will flow out to the outside thus to feed very small amount of liquid in the cylinder section to the screw- lock section of machine with predetermined time.
