A storage container of a coating tool can effectively prevent a coating liquid from sticking to a handle member of the coating tool. The storage container for storing the coating tool comprises a holding container for containing the coating tool and a closure member for closing the holding container with the coating tool contained in the holding container. The coating tool is provided with a handle to be used by the user to hold the coating tool, and the closure member is provided with an opening that allows the handle to pass through. When the holding container is closed by means of the closure member with the coating tool stored in the holding container, the handle of the coating tool projects outward through the opening.

Coating tool and storage container

A container includes an inner layer portion for liquid, an outer layer having an inner shape substantially equivalent to an outer shape of the inner layer, with the outer layer having an air vent communicating from between the two layers and the ambient, and a dispensing portion. When liquid is dispensed, the inner layer peels off the outer layer. The inner layer and the outer layer are bonded, in a first region, to each other with a force such that the inner layer is peelable from the outer layer by change of pressure, and the inner layer and the outer layer are bonded, in a second region, to each other with a force which is larger than that in the first region, by which the inner layer peels off the outer layer in the second region after the inner layer peels off the outer layer in the first region.

Liquid container and liquid container manufacturing method

A liquid discharging method for a liquid head discharge head. The head has discharge ports, liquid flow paths, bubble generating areas, bubble generating means, liquid supply ports connecting the flow paths with a common liquid supply chamber, and a movable member in the flow paths supported with a minute gap to the supply ports. The area of the movable member surrounded at least by its free end and both sides continued therefrom is larger than the opening area of the supply ports. The method includes the step of setting a period for the movable member to substantially close the opening area during the period from the application of a driving voltage to the bubble generating means to the substantial termination of isotropical growth of the entire bubble by the bubble generating means. Growth of the bubble component in the direction opposite the discharge port can be suppressed, improving liquid refill.
