A container closure comprises an annular region forming a counterface against which a gas permeable, liquid impermeable sealing element may be applied so as to urge the sealing element into sealing engagement with the rim of a container opening. The annular region comprises a gas pathway from an interior space opposite the container opening to the exterior of the annular region. The gas pathway may be of closed cross-section extending through the annular region. Alternatively the gas pathway may be of open-sided cross-section and provided in the counterface. Yet alternatively the annular region may comprise a washer, with the gas pathway provided at least partly in the washer and/or at least partly in the remainder of the annular region. A gas permeable, liquid impermeable sealing foil for bonding to a container rim is also disclosed.

The present invention relates to a storage container comprising a container body, a lid placed on the container body, and at least one latch shiftable between a latched position locking the lid in the closed configuration, and an unlatched position permitting to release the lid to the open configuration. The latch is configured to include an actuator portion by which the latch is pivotal between the latched and unlatched positions, and a latch portion having a fulcrum operably carried on the top rim of the container body during the pivotal movement of the latch, and the latch portion pivots upward and downward about the fulcrum to lift and lower the lid so that the lid is movable between the closed and open configurations. The mechanism for opening and closing the storage container by implementing the latch is simple and effortless to operate.

The present invention relates to a closure means for closing the opening of a container, said closure means comprising: a) a lid assembly, comprising: a lid cover, configured to provide an upper plate and a lower plate connecting said upper plate via standing wall therebetween, said upper plate is provided with at least one hinge member; at least one wing member comprising a handling portion, a flipping portion, and a stopper portion, said wing member pivotably connecting to said lid cover at said hinge member and thus movable between a first position where said stopper portion being away from said upper plate of said lid cover and a second position where said stopper portion being engaged with said upper plate of said lid cover and thus the upward movement of said wing member with respect to said lid cover being limited; and b) a sealing element, fittingly mounted around said standing wall of said lid cover; and characterized in that, in a first configuration where said container being closed with said closure means, said wing member being moved from said first position to said second position causing said closure means being moved upwards automatically.

The present invention relates to a method for channeling gas during sealing a container with a closure means and/or unsealing a container that is sealed with a closure means, comprising the steps of: A) providing a closure means comprising: a) a lid assembly having: a lid cover, configured to provide an upper plate and a lower plate connecting said upper plate via standing wall therebetween, said upper plate is provided with at least one hinge member; at least one wing member, pivotably connecting to said lid cover at said hinge member, comprising a handling portion, a flipping portion, and a stopper portion for limiting the upward pivoting of said wing member with respect to said lid cover by engaging with said upper plate of said lid cover; and a gas channeling means; and b) a sealing element, fittingly mounted around said standing wall of said lid cover; and B) providing a container having surrounding wall having a first edge connecting to a bottom and a second edge defining an open-top for said container, wherein said second edge is configured to support said flipping portion of said wing member; and characterized in that, gas being channeled through said gas channeling means, during closing said container with said closure means and/or opening said container that is closed with said closure means.

A closure means for closing an opening of a container includes a lid assembly having a lid cover, configured to provide an upper plate and a lower plate connecting the upper plate via a standing wall. The upper plate has at least one hinge member. A wing member includes a handling portion, a flipping portion, and a stopper portion. The wing member pivotably connects to the lid cover at the hinge member and moves between a first position and a second position. The upward movement of the wing member is limited. A gas channeling means having a first configuration where the container is closed with the closure means. The gas channeling means is biased. The wing member moves from the first position to the second position causing the closure means being moved upwards automatically and causing the gas channeling means transiting from a biased condition to an unbiased condition.
