A refillable ink box proofed against the formation of airlocks during filling includes an ink storage chamber, a seat, and an insertion tube. The box includes a bottom plate, and first and second side walls. The bottom plate and first and second side walls form the ink storage chamber. The seat protrudes to the exterior and carries insertion tube, ink outlet, and air guiding port. The insertion tube defines the ink inlet and also an air vent. The ink inlet communicates with the ink outlet port, the ink outlet communicates with the ink storage chamber. The air guiding port equalizes gas pressure with outside atmosphere and is positioned above the ink outlet.

A liquid supplying apparatus includes a support table on which a container for storing liquid can be placed, a liquid flow path detachably connected to the container, a movable section configured to push up the container placed on the support table. A force of the movable section pushing up the container is smaller than a weight of the container at full capacity. As the residual amount of liquid decreases, the container placed on the support table is pushed up by the movable section and displaced while remaining connected to the liquid flow path.

The container includes an ink well and a base for the ink well. The ink well has a side defining an open top. It also has a bottom surface. The base includes a base wall configured to receive the well. The base wall has an upper section surrounding and engaging the well side proximate the open top of the well. It also has a lower section extending downwardly from the upper section. The lower base wall section includes at least one set of spaced legs. The spaced legs define a recess adapted to receive a leg of another similarly shaped container in order to interlock the containers in various arrangements.

The liquid cartridge for an industrial inkjet printer for printing goods has a film bag, a connector stub connected thereto, and a lower cap. The connector stub has an opening which is closed by the lower cap which has a lower rubber layer, a plastic layer formed by the connector stub, and a lower holder. The lower holder has a lower window which is situated above the opening. The lower holder is fastened to an outer side of the connector stub. The lower rubber layer and, underneath it, the plastic layer are situated below the lower window, and they are in contact with one another and with the lower holder.

It is an object to provide a cylindrical molded article that is also excellent in smell retention properties for smelling substances in addition to oxygen barrier properties and is also excellent in the fine appearance of a cut surface when cut, and a barrier plug, a barrier plug-attached container, and an tube for storing ink each using the same. A cylindrical molded article comprising a cylindrical resin layer comprising a resin having a melting point of 140 C. or more; and a vapor-deposited layer disposed on an outer peripheral surface of the resin layer, the vapor-deposited layer comprising at least one selected from the group consisting of silicon oxide, aluminum oxide, and diamond-like carbon, and the cylindrical molded article having a total thickness of 100 m or more.

It is an object to provide a cylindrical molded article that can inhibit the transmission of components having SP values in a relatively wide range. A cylindrical molded article having a cylindrical resin layer I comprising a vinylidene chloride copolymer; and a cylindrical resin layer II disposed inside the resin layer I and comprising a resin having an SP value of 12.0 (cal/cm.sup.3).sup.1/2 or more, and having a total thickness of 100 m or more.

An inkwell apparatus comprises an inkwell vessel and a cap for covering a vessel opening in an apparatus storage position. The cap has a protruding tip upon which to support the inkwell in an apparatus spinning position or a pooling position. A bottom (e.g. support surface) of the inkwell forms at least one of: i) a central region providing a tip engaging surface dimensioned to receive the tip in the spinning position; or ii) at least one tip engaging latch surface, each tip engaging latch surface dimensioned to receive the tip in the pooling position. Methods of use relate to the spinning position and the pooling position. The cap can comprise a seal ring to seal the opening or to provide support assistance in the spinning or pooling position(s). Ribs in the inkwell can provide deflection of ink when stirred such as by spinning.
