Abstract: Provided is an ink container suitable for forming a stable high-quality print image and obtaining stable operation of a printing device by enabling precipitates of coarse-grained ink etc. standing in an ink container body to be left in the ink container body and by eliminating troubles due to the supply of such precipitates of coarse-grained ink etc. to the printing device. A region for residual ink liquid 4 and a sheet-entry preventing member 6 as shape retaining means 5 are provided on the bottom 2a side of a bag-like ink container body 2 formed from a flexible sheet. The region for residual ink liquid 4 is disposed in a position lower than one end 3a of an ink supply opening part 3 fixed to the ink container body 2. When the sheet composing the ink container body 2 moves, the sheet-entry preventing member 6 prevents the sheet from entering the region for residual ink liquid 4, thereby keeping the shape and volume of the region part for residual ink liquid 4.

Abstract: An ink container filling structure comprising an ink container removably mountable in a recording device, and an ink container filling section having a fit section in which the ink container is filled and which fits in the delivery port of the ink container, wherein when the ink container is removed from the ink container filling section, the ink is prevented from dripping from the ink delivery port to soil the operator's hand or the ink container filling section peripherals. It is arranged that the direction (the direction of arrow (A)) of fitting the fit section (20) in the delivery port (11) of the ink container (1) is obliquely downward with respect to the horizontal direction.

Abstract: An ink container loading structure includes an ink container provided with a container body in which ink is stored and an ink discharge port through which ink in the container body is discharged and an ink container loading portion provided with an ink container engagement portion in which the ink container is loaded and with which the ink discharge port of the ink container is engaged. The ink container engaging direction of the ink discharge port of the ink container with the ink container engagement portion is directed obliquely downward with respect to the horizontal.

Abstract: 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.

Abstract: 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.

Abstract: A variable volume container includes a cylindrical main body having an end wall at an end thereof; an outlet projecting from an outer surface of said end wall for allowing a content to be supplied; a piston member fitted into said main body sealingly and slidably in an axial direction of said main body for defining a variable volume storage chamber between itself and said end wall; a plug member detachably mounted to said outlet; and an impact resisting reinforcement disposed at said end wall. The reinforcement may be a part of said end wall having a thickness gradually increased toward said outlet, or may be a rib shaped projection. Such a variable volume container placed upside down in packaging or transport is reinforced at the end wall of the main body where the outlet is disposed. Thus, impact is not concentrated at the root portion of the outlet but distributed, so that the outlet is prevented from being damaged, and the container is placed more stably.

Abstract: 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.

Abstract: A liquid container is provided, which comprises a bag-forming flexible container body, a pouring outlet provided to communicate with an inside of the container body, and a support member provided in the container body for inhibiting deformation of the container body occurring near the pouring outlet when the contained liquid is sucked, in which the support members is a member reinforcing the container body with a form like a funnel narrowed at the pouring outlet. If the funnel-like reinforcing portion occupies almost one half of the surface area of the container proper, it can be prevented that the pouring outlet is closed even if the non-reinforced portion of the container body is housed in the support member when the contained liquid is discharged. Therefore, a contained liquid can be smoothly taken out, and the container is especially suitable for containing a liquid having a relatively high viscosity or a liquid sensitive to the contact with air and the like.

Abstract: 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.
