Japanese Unexamined Patent Publication No. 7-62 (Japanese Utility Model Laid-Open No. 62-130072) discloses a container having a structure shown in an exploded view in FIG. This container consists of the outer cylinder (1), the inner container (2), the support (3) and the inner ring (4), and the inner container (1) is applied by one finger pressure from the back of the support (3). A drop of contents is discharged from the tip of the nozzle (2g) of 2). The role of the inner ring (4) is that the nozzle (2g) of the inner container (2) is opened or after the nozzle (2g) is opened.
When axial pressure is applied to (g), pressing force is applied to the protruding part (2a) of the inner container (2) to prevent the contents from being discharged from the tip of the nozzle (2g). It is a thing.

[0005]

A container of a type in which the body of a container with a nozzle is held and pressed by a finger to discharge the contents from the nozzle controls the discharge amount only by the holding pressure by the finger. Therefore, unless careful attention is paid to the timing of pressing and the pressure, there is a risk that several drops of adhesive may be discharged at one time.

An adhesive tool in which a cartridge-type adhesive container is inserted into a tool equivalent to a syringe controls the insertion amount of a piston into a cylinder with a finger.
After all, if you do not pay close attention, there is a risk that several drops of adhesive will be discharged at one time.
