A water-in-oil (W/O) emulsion ink for stencil printing is provided, which is excellent in emulsion stability and drying, high in printing density and low in blurring and seep through. The W/O emulsion ink has an oil phase and a water phase, in which an acid anhydride containing water-soluble polymer is contained together with a water-insoluble colorant in said water phase. The acid anhydride containing water-soluble polymer is preferably an acid anhydride containing olefin copolymer, more specifically, an isobutylene-maleic anhydride copolymer, or an acid anhydride containing vinyl copolymer, more specifically, a styrene-maleic anhydride copolymer. Preferably, the oil phase comprises at least a solvent and an emulsifier, and the water phase comprises a water-in-oil (O/W) emulsion of resin and/or a water-soluble resin.

A container for fluidal materials, including a bag member made of a flexible film material originally constructed in a flattened shape with some foldings, a port member mounted to the bag member at its longitudinal end, and a plate member mounted over the bag member as originally constructed in a flattened annular sheet member made of a relatively stiff and elastic sheet material such as a cardboard, wherein the plate member is expanded into a tubular shape when the bag member is charged with a fluidal material but is readily flattened for disposal after the fluidal material has been discharged from the bag member.

A container for a fluid includes a carton of a long hollow shape having an inner surface, and an inner bag attached to the inner surface of the carton for containing the fluid in it. The flexible inner bag has a fluid-discharge port. The inner bag is separated from the carton according to discharging of the fluid. The container also includes a separation detecting device. This device is disposed along a separating direction of the inner bag, which is separated according to taking out of the fluid.

A container is provided which comprises a cylindrical main body having an end wall at an end thereof; an outlet projecting from an outer surface of the end wall for allowing a content to be supplied; and a protecting member disposed on the outer surface of the end wall so that it surrounds the outlet and defines a groove portion between the outlet and the protecting member. The protecting member is preferably a continuous or discontinuous annular projection. A conduit of a pump can be coupled to the groove portion by engaging an inner circumferential surface of the protecting member with an outer circumferential surface of the conduit, or by engaging an outer circumferential surface of the outlet with an inner circumferential surface of the conduit.

A liquid container is provided, which comprises a container body provided as an elongated flexible bag having a closed end face at an end thereof, a pouring outlet formed at the closed end face of the container body, and a support means for preventing deformation of a side face of the container body in its front portion adjacent to the closed end face, whereby a rear portion of the container body which is not reinforced by the support means is housed into the front portion as the contained liquid is discharged, in which the liquid container further comprises a stopper which is disposed on the side face of the rear portion of the container body for engaging with the front portion of the container body, whereby after the stopper has been engaged with the front portion, portion of the rear portion in front of the stopper is prevented from being further housed into the front portion. The liquid container allows the length of the container after use to be reduced to less than one half the length before use, and furthermore even in the case where the length of the container body is long, allows the rear portion to be well housed in the front portion, for stably allowing the contained liquid to be taken out.

An ink bottle mounting apparatus comprising a bottle mounting apparatus body 11 having an ink bottle 1 and a bottle insertion chamber 12 into which the ink bottle 1 is inserted, wherein the ink bottle mounting apparatus further comprises a bottle lock member 15 which is engaged with a groove 5 formed on a side peripheral surface of the ink bottle 1 to prevent the ink bottle 1 from being pulled out when the ink bottle 1 is mounted to the bottle mounting apparatus body.
摘要:
An ink container has a cylinder provided with an ink discharge port at its leading end and a piston fitted in the cylinder to be slidable along the inner surface of the side wall of the cylinder. Ink is filled into the space defined by the cylinder and the piston. Resistance generated by friction between the cylinder and the piston when the piston is slid toward the ink discharge port with the ink container held empty is not lower than 1.0N.
摘要:
The present invention provides a cylinder/piston type volume reduction container which does not occupy much space for storage and transportation, and is easy in disposal and recovery. The container comprises a head tubular body (1) an end of which is closed by an end wall (11) having an outlet (12) for content, a rear tubular body (2) which is fitted in the head tubular body and movable in an axial direction of the head tubular body, and a piston member (3) which is fitted in the rear tubular body and movable in an axial direction of the rear tubular body. The rear tubular body may comprise a plurality of tubular bodies nested in telescopic manner. The rear tubular body and the piston may respectively be fitted in the head tubular body and the rear tubular body by way of scraping members (21, 22, 31, 32) provided on an outer peripheral surface of the rear tubular body or the piston. A spacer (25) may be provided protruding from the outer peripheral surface of the rear tubular body toward the inner peripheral surface of the head tubular body.
