Dispenser for viscous material

摘要

A dispenser for a single cartridge has a yoke (16) pivotably mounted on a stock (10). The yoke (16) has a square-section open end and a circular section closed end. One flat side on the square section end provides an abutment for defining the closed position of the yoke (16). The stock 10 has a similar flat surface that engages the flat side of the yoke (16). The flat surface on the stock (10) is easily formed in the manufacturing process.
