A closure and filter for a multi-use water bottle. The closure has a main body having an outlet through which fluid passes to be consumed by the user and an air valve remote from the outlet to provide an air channel through the closure distinct from the fluid outlet to allow flow of air into the bottle as fluid passes through the outlet.

A display container includes an enclosure having a container body and a lid mounted to the container body for enclosing an interior chamber of the enclosure. The lid has an integrated lens positioned over the interior chamber and a plurality of ports extending through the lid adjacent the lens. The display container further includes a slide valve assembly for selectively opening and closing the ports. The slide valve assembly includes a track fixed relative to the lid in alignment with the ports, and a slide plate slidably received in the track. The slide plate is slidable back and forth along the track between a first position in which the slide plate blocks the ports and a second position in which the ports are unblocked.

A drinking vessel may include a tumbler having an inner surface dimension, a first portion, and a second portion. The first portion may include a proximal surface having a first dimension and a first rim coupled to the proximal surface and having a second dimension, the first dimension being larger than the second dimension. The second portion may include a collar having an outer dimension substantially similar to the first dimension, an inner dimension substantially similar to the second dimension, and a second rim connected to the collar and having an outer dimension substantially similar to the second dimension and the inner surface dimension.

A container for heating and cooking food includes: a lower containment body; an upper cover hermetically coupling with the lower containment body; and an automatic valve, in the shape of a cap, integrated in the upper cover, allowing steam to vent. The automatic venting valve includes: a control member controlling the pressure inside the container; and an elastic tongue associated and moulded in one piece with the control member. The control member is housed and rotatable in a recess in the upper cover. The elastic tongue has a deformed configuration, applying an elastic force pressing and closing the control member against a through hole in the bottom of the recess housing the control member, preventing the steam from exiting the container. When the steam pressure reaches a critical value, the control member rotates and tilts, removing the control member from the through hole, allowing the steam to vent.

Disclosed herein is a lid for mounting on a cup opening defined by a brim of a cup body. The lid comprises a cover having a substantially planar portion and a recessed opening disposed on the cover; a side wall disposed around the periphery of the cover; a flange extended from the bottom edge of the side wall and forms a trench space for accommodating the brim of the cup body when the lid is mounted on the cup opening; and a breathable film disposed below the substantially planar portion and covered the recessed opening of the cover. The cover and the breathable film of the present lid are integrally formed into a single piece.

A cover device (2) for a drink container comprises a basic assembly (9) which is provided with a drink opening (32), and a valve arrangement (20) for blocking or unblocking a passage to the drink opening (32) from a drink container side of the cover device (2). The valve arrangement (20) comprises a valve element (26) having two portions (27, 28) which are connected to each other through an area of the valve element (26) at a position where the valve element (26) is hingably associated with the basic assembly (9), and wherein only one of the two portions (27, 28) is in direct communication with the drink opening (32) of the basic assembly (9), so that a smallest total moment of force may be realized on the one portion (28) when the valve element (26) is subjected to pressure from the drink container side of the cover device (2).

A container and closure combination, for the containment of fluids and extraction therefrom by way of an extraction tube. The container comprises a closed volume with an opening configured to close the opening of the container; the closure is provided with an aperture such that the closure, upon fitment to the container opening, cannot be removed therefrom. The aperture of the closure comprises a unitary elastic unidirectional valve member that can operate in a first, closed condition, to prevent a flow of fluid from the container; and a second, operational condition, with an extraction tube sealingly engaged with respect to the valve, to permit an extraction of fluid from the container through the tube.

The present invention provides a treatment liquid exhibiting excellent selectivity in dissolving SiGe in a case where the SiGe is etched with the treatment liquid. The present invention also provides a treatment liquid container relating to the treatment liquid.

The treatment liquid according to an embodiment of the present invention contains a fluoride ion source, an oxidant, an acetate solvent, and an additive, in which the additive is an additive that does not contain a Si atom.

A lid for a drinking container includes a lid body, a poppet mouthpiece and a resilient sealing member. The lid body defines a longitudinal axis and includes an outer surface with a vent hole. The mouthpiece seals against a first inner surface of the lid body via an annular seal ring. The mouthpiece is movable between a closed position and an open position to allow fluid inside the container to flow through the mouthpiece. The sealing member is fitted on the lid body to sealingly engage the lid body to an open end of the container. The sealing member includes an annular flange sealingly engaging a second inner surface of the lid body. The flange includes a groove that defines a location on the lid where ambient air flowing into the vent hole can enter a container interior as fluid flows out of the container through the mouthpiece.

A leak resistant lid assembly for a beverage container where the lid assembly has a straw or similar means for a user to drink liquid is disclosed. The lid assembly may include a base, a straw that extends through the base, a gasket, and a grommet. The base may have a primary opening that receives the straw and a secondary opening in the top of the base, where the secondary opening acts as a vent to prevent a vacuum from occurring when drinking from a straw. The grommet may have a spiral ring may help create a flow path for air from inside the beverage container to the exterior environment.
