A composite container lid includes an inner plug 1 with a flow-out port and an upper lid 3 detachably attached to a container mouth portion 80, wherein: the inner plug 1 includes an upper lid engaging cylinder 5, a container mouth portion-securing member 7 having a circumferential wall 9 that surrounds the upper lid engaging cylinder 5, and linking pieces 11 that link the inner surface of the circumferential wall 9 to the upper lid engaging cylinder 5 so as to form a flow-out port 13; the upper lid engaging cylinder 5 is provided, on the upper end portion of the outer surface thereof, with a circumferential protuberance 5a for temporary engagement; engaging pieces 37 are formed on the inner surface of a top plate 31 of the upper lid 3, the engaging pieces 37 having an undercut 37a for temporarily engaging with the circumferential protuberance 5a that temporary engages with the upper lid engaging cylinder; and a sound-suppressing protrusion 50 is provided in a region surrounded by the engaging pieces 37.

An ink refilling container includes a bottle and a cap. The bottle includes an ink outlet forming portion including an ink outlet and a valve. The valve has valve segments segmented by slits. The cap includes a top portion, which faces the ink outlet when the cap is put on the bottle. A protruding portion extending in the central axis direction is provided at the center of the top portion. An annular-shaped sealing portion is provided on the top portion radially outside the protruding portion. The radius of the protruding portion is less than the length of the slit. In a sealed state wherein the cap is in thread engagement with the bottle and wherein the sealing portion seals the ink outlet, the tip end of the protruding portion is inserted in the inside of the bottle through the slits at the center region of the ink outlet.

This disclosure relates to a lid assembly that has a lid assembly for a container, such as a drinking container, that includes a lid member, and a pouring member, wherein the lid member and pouring member are releasably connected to the container. The lid member may include a body member, a handle portion connected to the body member, an internal threaded portion, an internal receiving portion, and a lid gasket member arranged in the internal receiving portion. The pouring member may include a spout collar, a spout, and a spout opening extending through the spout, wherein the spout extends from the spout collar and includes an upper end above an upper surface of the spout collar. The lid assembly has a closed orientation that prevents liquid from flowing through the opening of the pouring member and an open orientation that allows liquid to flow through the opening of the pouring member. When the lid assembly is in the closed orientation, the lid gasket member contacts both the upper end of the spout and the upper surface of the spout collar.

A liquid storage container includes: a discharge port member including a discharge port through which liquid stored in a storage portion is discharged; a cover portion configured to be attachable to the discharge port member and to be capable of opening and closing the discharge port; and a sealing portion formed of a contact portion between the cover portion and the discharge port member. The cover portion includes a groove structure between an outer periphery of the cover portion and the sealing portion.

A liquid storage container includes: a discharge port member including a discharge port through which liquid stored in a storage portion is discharged and a coupling portion in which a male thread portion is arranged on the outside; and a cover portion including a female thread portion on the inside and configured to be attachable to the discharge port member, the female thread portion configured to be screwed to the male thread portion, in which the male thread portion is discontinuous in the coupling portion.

A storage container includes an elastomeric base having a plurality of side walls forming an interior and an opening at an upper edge of the base. The base has an annular channel positioned proximate the opening at the upper edge of the base. An inner insert is removably positionable in the opening of the base, the inner insert having an outward facing annular protrusion configured for insertion in the annular channel of the base, and a spout with a channel formed therethrough. At least a portion of the spout has external threading. An outer cap is positionable over the inner insert and has an opening for receiving the spout. A screw cap includes internal threading configured for rotational engagement with the external threading of the spout, wherein rotation of screw cap compresses at least a portion of the base between the inner insert and the outer cap.

A container lid (2) can be removed from a mouth-neck section (106) of a container without the need for a tool. Following the breakage of a breakable thin-walled line (70) in a transition region (52), the breakage of a breakable thin-walled connection wall (68) in a side wall separation region (54) can be started sufficiently smoothly in the container lid (2). For this purpose, the breakable thin-walled line (70) formed in a side wall (10) in the transition region (52) is brought into a form in which at least a part thereof extends obliquely downwardly in a counterclockwise direction.
