Title:
NOZZLE AND METHOD OF USING IT
Document Type and Number:
Japanese Patent JP2003239524
Kind Code:
A
Abstract:

To make it possible to accurately abut a nozzle on a construction place without allowing it to come into contact with the construction place in a condition in which it is inclined for the construction place and there is a clearance even if the nozzle is once separated from the construction place and is abutted on it again.

A cartridge (storage member) 3 of filler K is fitted in play into a barrel 2 of a calking gun 1, namely, it is mounted in such a way that it can be shrunk in the longitudinal direction of the barrel 2 and can turn in the axial direction. A nozzle 4 is detachably screw-fitted in its tip. The nozzle 4 is provided with a distinguishing part 4a which is linear in the longitudinal direction in a semiperipheral part 4A on one side, and a semiperipheral part 4B on the other side can be distinguished by the distinguishing part 4a. When the distinguishing part 4a is put at a position just on a side of the nozzle 4 using the distinguishing part 4a as a mark prior to calking work, a position just above (central line C) becomes just a boundary of the semiperipheral part 4A on one side and the semiperipheral part 4B on the other side. When cutting from the position of the boundary as shown by a dotted line L, it is securely cut in such a way that the distinguishing part 4a becomes just a central line of the semiperipheral part 4A on one side, a tip opening part 5 of the nozzle 4 is opened in an elliptical shape. The semiperipheral part 4A on one side protrudes forward, and the semiperipheral part 4B on the other side is formed into a backward recessed condition.
