Abstract: When a known lid member was merely applied to a bottle that contains ink, there was room for improvement in terms of the operation of the lid member and the way how to bring attention to the handling thereof. A bottle set is provided that includes: a bottle that includes an ink container that contains ink, and an outflow port through which the ink in the ink container flows out to the outside; and a lid member that is configured to attach to and detach from the bottle, and is configured to cover the outflow port in a state of being attached to the bottle. The lid member includes a colored portion that has optical transparency and is colored with a color corresponding to a type of the ink contained in the ink container in at least a portion of the lid member.

Abstract: A printer includes: a first ink tank; a second ink tank, both mounted on an X-Y plane; and a window that enables a liquid level of each of the first and second ink tanks to be visually checked from an outside of the printer, the window being disposed in an X-Z plane or a Y-Z plane. The X-Y plane, X-Z plane and Y-Z plane are defined by X-, Y-, and Z-axes, which are mutually orthogonal to. Each of the first and second ink tanks includes a first segment and a second segment, the first segment for arranging the first ink tank and the second ink tank side by side in a direction along the Y-axis, the second segment positioned out of alignment with the first segment in the X-axis direction. At least one of the first segment and the second segment has a visual check section facing the window.

Abstract: There is provided an ink replenishment container for replenishing ink into an ink tank via an ink inlet flow path member, the ink replenishment container including a container main body, an ink outlet forming portion having a tubular portion, a spring valve having a valve body mounted in the tubular portion and a spring for urging the valve body toward the ink outlet, and a sealing member mounted in the tubular portion and having a sealing end configured to contact with the valve body in a valve close state, in which the sealing member has a cylindrical inner peripheral wall and an elastic membrane portion extending from the inner peripheral wall toward a center, and the elastic membrane portion is formed with a slit-shaped gap passing through a center portion including the center.

Abstract: There is provided an ink replenishment container for replenishing ink into an ink tank via an ink inlet flow path member having a plurality of flow paths, the ink replenishment container including a container main body, an ink outlet forming portion, and an outlet valve unit. The outlet valve unit includes a valve housing mounted to provide a gap with an inner peripheral surface of a tubular portion in the tubular portion, a sealing member, and a valve body movable between a valve close state in contact with the sealing member and a valve open state separated from the sealing member. The valve body has a partition contact portion capable of contacting a partition of the ink inlet flow path member. The valve housing has a through-hole that communicates with the gap, and the through-hole communicates with the ink inlet flow path member in the valve open state.
