摘要： The invention relates to an implement, especially a writing implement, for applying a liquid onto a base by means of an application element (12). Said implement comprises a liquid-containing chamber (6) for receiving a supply of liquid and a capillary liquid duct (16) for supplying the application element (12) with the liquid. The implement is further provided with a capillary reservoir (18) for temporarily receiving liquid when the air pressure and/or the temperature changes, said reservoir directly contacting the liquid duct (16) outside the liquid-containing chamber, and with an aeration path (22, 4) which at least partially extends through a capillary material (4) and through which air flows into the liquid-containing chamber when the liquid volume taken up in the liquid-containing chamber decreases. The capillary actions of the liquid duct are greater than those of the capillary material of the aeration path and the capillary actions of the reservoir are smaller than those of the capillary material of the air intake. At least a part (4) of a wall (2, 4) of the liquid-containing chamber (16) consists of a capillary material and constitutes a part of the aeration path (22, 4). The smallest capillary action of the capillary material of the aeration path is greater than those of the major part of the reservoir (18) and is smaller than the smallest capillary action of the liquid duct (16).

摘要： A writing instrument (10) is disclosed having a barrel (12) defining an internal passage including an ink reservoir. A venting mechanism (20) is positioned at least partially within the internal passage of the barrel adjacent and anterior end portion thereof. The venting mechanism (20) includes an elongated body defining an axial bore therethrough in communication with the ink reservoir (24), and a plurality of spaced apart fins (32) peripherally surrounding the elongated body and defining a plurality of annular channels between the fins. Each of the fins defines a groove thereon to interconnect the annular channels. The writing instrument further includes a point support member (16) supporting a writing point (18) and positioned adjacent an anterior end portion of the venting mechanism and defining an axial bore aligned with the axial bore of the venting mechanism. A first ink supply rod (48) is disposed within the axial bore of the venting mechanism and has a posterior end portion in communication with the ink reservoir to convey ink from the ink reservoir to an anterior portion of the venting mechanism. A second supply rod (50) conveys ink from a posterior end portion disposed within the bore in the venting mechanism and contacting the first supply rod to an anterior end portion disposed within the bore of the point support member, to the writing point. A circuitous air path is provided to vent the ink reservoir at the posterior end portion to the writing tip portion.

摘要： A reservoir type writing pen having a micro-porous straight-liquid structure comprises a writing pen core (9); wherein the micro-porous straight-liquid structure includes an air pressure balance plug (3), a liquid storage pipe (11) configured for storing liquid ink, and a liquid guiding device configured for leading the liquid ink in the liquid storage pipe (11) into the writing pen core (9). The present application adopts the gap between the relaying pen core and the writing pen core, the ventilating core and the nano breathing plate to realize keeping the inner air pressure of the liquid storage space and the outside atmosphere pressure consistent. The writing pen of the present application has a simple structure, and the producing processes of the ventilating core have been matured, which can reduce the producing cost greatly.

摘要： Provided is a writing instrument, having high cartridge replaceability and excellent convenience, that is capable of suppressing inappropriate ink leakage that easily occurs when a used cartridge container is pulled out even when the writing instrument uses a replacement ink cartridge with a plug to be press opened. A writing instrument includes: a replacement ink cartridge including a bottomed cylindrical container that has an opened front end and a closed rear end and a plug fitted into an inner circumferential surface of an opening of the container; and a projection inserted into the opening of the container to press the plug rearward, thereby opening the plug of the ink cartridge, wherein the projection and the plug are fitted when the plug is press opened, and when the cartridge is replaced, the fitting between the projection and the plug is released and the plug is locked again in the opening of the container.

摘要： A pressure fluctuation buffering mechanism 180 includes a buffer space K connected to a brush 120 via a paint flow space (a paint tank 140 and a paint feeder 160) through which paint flows. The pressure fluctuation buffering mechanism 180 buffers pressure fluctuation in the paint tank 140 by the flow of paint and air between the paint flow space and the buffer space K. The pressure fluctuation buffering mechanism 180 includes: a first buffer space forming member 183 for forming a first buffer space K1 in the buffer space K; and a second buffer space forming member 184 for forming a second buffer space K2 in the buffer space K. The paint between the first buffer space K1 and the paint flow space flows more easily than the paint between the second buffer space K2 and the paint flow space.
