A container of the present invention has an inner surface formed of an olefin resin layer that includes an organic bleeding lubricant and in which an inorganic porous agent is blended.

A device that assists with equalizing air pressure within a bottle with the atmospheric air pressure as liquid is being poured from the bottle and includes one or more relatively short air tubes. The air tubes are situated with an upper inlet rim of the air tubes located flush with or relatively near the bottle rim. Whether an insert or integrated into the manufacture of a container, the one or more air tubes that extend partially into the container allow air to pass into the container as the liquid exits the container. The pressure equalizer not only minimizes or prevents the common glugging effect, but it allows liquid from a bottle to be poured smoothly at any angle and orientation. A cap incorporating a detachable pressure equalizer is also described.

The present invention relates to devices for liquid storing and using, namely a frame structure supporting stand with swing joining elements and a bottle with the necks for pouring out the contents and the tubes for overflow of the contents. The holder with the bottle contains a frame consisting of vertical rods mounted between two support platforms within which the bottle is placed. The bottle is attached to the frame through a support platform. The frame is fixed on the holder axes with the possibility of rotation about the holder due to the swing joint. Additional external elements are provided on the support platforms, they allow opening/closing of the bottle neck. The holder has a mounting stand. The swing joints of the holder and the frame are configured to fix the frame with the bottle in the desired position relative to the axis of the holder.

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.
