<P>PROBLEM TO BE SOLVED: To achieve reduction in remaining amount of a lubricant, prevention of futility of the lubricant and labor saving by reducing a level difference formed in a container body as much as possible thereby preventing the lubricant to remain due to sticking of the lubricant inside the container body. <P>SOLUTION: A cartridge tank T which is made of a flexible resin and is molded by blow molding, includes: a bellows tube-like container body 1 which has one closed end and is stretchable in an axial direction; and a tube-like mounting mouth 5 which is interconnected integrally with the other end side of the container body 1 and has an opening 6 formed therein. A groove 20 extending along a circumferential direction is formed at an outer side of a base end 8 of the mounting mouth 5. When the lubricant L is filled into the cartridge tank T, an engagement member 30 is engaged and held in the groove 20 in the mounting mouth 5 and the cartridge tank T is suspended such that the container body 1 is located at a lower side. In this state, the lubricant L is poured from the opening 6 in the mounting mouth 5 and the cartridge tank T is filled with the lubricant L by allowing the container body 1 to be stretched by the weight of the lubricant L. <P>COPYRIGHT: (C)2012,JPO&INPIT |
