Liquid container having sliding closure means

A liquid container comprising a closed vessel, there being two apertures in the top of the vessel, one serving as an outlet through which liquid can be poured from the container and the other serving as a vent hole, a closure member and constraining means whereby the closure member is constrained for sliding movement relative to and in contact with the vessel between one position in which it closes the two apertures and another position in which both the apertures are open to allow a discharge of liquid from the container through the outlet;

• the closure member being a flat elongate slider which is constrained by said constraining means for lengthwise rectilinear sliding movement relative to the vessel;
• wherein a layer of elastomeric material is formed on the underside of the slider, and the means whereby the slider is constrained for sliding movement relative to, and in contact with the vessel causes the elastomeric material to be slightly compressed in reaction to its contact with the vessel.

A liquid container comprising a closed vessel which comprises an open topped portion and a hinged lid, the open topped portion comprising a base and sides of the vessel, the hinged lid being pivoted relative to the open topped portion and having two apertures formed in it, one of the apertures serving as an outlet through which liquid can be poured from the container and the other serving as a vent hole;

• a closure member;
• constraining means on the lid whereby the closure member is constrained for sliding movement relative to and in contact with the lid between one position in which it closes the two apertures and another position in which both the apertures are open to allow discharge of liquid from the container through the outlet;
• and puncture means associated with each aperture and depending from the lid, there being passages in each puncture means which provide form communication between the interior of the vessel and each aperture when the lid is closed, whereby the act of closing the lid on an appropriate sealed liquid container placed within the open topped portion causes the top of the sealed liquid container to be pierced by the puncture means so that liquid contained therein can be poured through the outlet via the respective passage in the puncture means when the closure member is in its closed position.
