Abstract
A cartridge type liquid feeding container is capable of being used by refilling or replacing a liquid instead of throwing away the container itself, and can feed out the liquid inside the cartridge. The liquid feeding container includes a body, a manipulating body which is mounted movable with respect to the body and is made capable of being manipulated from an outside, a cartridge which is loaded into the body so as to be attachable and detachable, a liquid supplying body for supplying the liquid inside the tank portion to the outside, a piston rod which is workable on the piston to press the piston of the cartridge forward, and movable inside the cartridge case and body, and a conversion mechanism for converting a manipulating force applied to the manipulating body into forward movement of the piston rod.
Claims8
A cartridge type liquid feeding container, comprising:
- a body;
- a manipulating body capable of being manipulated from an outside;
- a cartridge which is loaded into said body so as to be attachable and detachable, and has a cartridge case, a tank portion located inside the cartridge case for housing a liquid, and a piston which slidably moves in the tank portion;
- a liquid supplying body for supplying the liquid inside the tank portion to the outside;
- a piston rod which is workable on the piston to press the piston of said cartridge forward, and is movable inside said cartridge case and body;
- and
- a conversion mechanism for converting a manipulating force applied to said manipulating body into forward movement of the piston rod,
- wherein said conversion mechanism comprises a thread engagement between the piston rod and the cartridge case, for screwing the piston rod into the cartridge case, and moving the piston rod forward by relative rotation between the manipulating body and the body, and
- wherein said thread engagement between the piston rod and the cartridge case is detachable.

- wherein said conversion mechanism comprises a thread engagement between the piston rod and the cartridge case, for screwing the piston rod into the cartridge case, and moving the piston rod forward by relative rotation between the manipulating body and the body,
- wherein the piston rod is biased in a direction to go away from the cartridge, inside the body;
- and
- wherein said thread engagement screws the piston rod into the cartridge case when the cartridge is located in a mounting position inside the body, whereas when the cartridge is out of the mounting position inside the body, said thread engagement loosens the screwing of the piston rod and the cartridge case.
