A lid of molded plastic construction, includes a lid body and a cap attached to the lid body by a tether. The tether is substantially continuous with an adjacent peripheral edge of the lid body, with a tear zone between the tether and the adjacent peripheral edge of the lid body formed during molding of the lid. The tear zone is disruptable by application of a tearing pressure to free the tether from the peripheral edge.

A canister including a lid and storage canister. The lid incorporates a gasket that is overmolded onto the lid during its manufacture. The gasket is exposed on both the upper and lower surfaces of the lid in order to provide a non-slip surface at the top portion of the lid and a sealing surface at the bottom of the lid for sealing a storage canister.

A stopcock controls the flow of a liquid under pressure through a dispensing tube with an upstream portion separated by the stopcock from a downstream portion. The stopcock includes a housing portion with a chamber defined by a housing peripheral wall surrounding a longitudinal z-axis. The housing peripheral wall has an inner surface of revolution with a housing inlet opening connectable to the upstream portion of the dispensing tube. The stopcock includes an outlet connector connectable to the downstream portion of the dispensing tube and comprising an outlet opening. A plug defined by a plug outer peripheral wall snugly fitting the inner surface of revolution of the housing peripheral wall. The plug can rotate within the chamber about the longitudinal z-axis. The plug has a through-channel extending from an upstream opening located on the plug outer peripheral wall, to a downstream opening, such that the plug can be rotated about the longitudinal z-axis from a flow position to a sealed position, wherein, the plug outer peripheral wall comprises a seal protrusion topped by a ridge and forming a closed loop defining a blank area of the plug outer peripheral wall, such that, in the sealed position, the housing inlet opening of the housing peripheral wall faces the blank area and is circumscribed within the seal protrusion. The plug outer peripheral wall has a flow protrusion topped by a ridge circumscribing the upstream opening such that, in the flow position, the inlet opening of the cylindrical chamber peripheral wall is circumscribed by the flow protrusion, wherein said flow protrusion preferably shares a common portion of protrusion with the seal protrusion.

A mold is provided for forming caps for closing containers by compression molding doses of plastic material, where a bottom wall of the cap, or at least one portion of the bottom wall is very thin. The mold includes two half-molds axially movable towards each other which assume an end closed position without a dose. A tubular element is slidable around the second half-mold and partially defines the cavity. The tubular element contacts an axial abutment of the first half-mold at one side and an axial end stop of the second half-mold at the other side to prevent hard contact between the half-molds.

A method of forming a bi-injected closure, comprising the steps of: forming a cap with a top plate and a depending sidewall, in a first injection moulding phase using a first mould part, the cap formed so as to include one or more external sealing areas; changing the first mould part for a second mould part, the second mould part sealing against the or each sealing area on the cap; and forming an outer ring around the cap sidewall whilst the second mould part is sealed against the sealing area/s in a second moulding phase.

A rubber stopper for a medicine container has a rubber stopper body and a coating layer directly applied to a surface exposed in the medicine container. The coating layer is more flexible than a forming material of the rubber stopper body. The said coating layer comprises a composition containing a silicone-based resin which comprises a condensate of a reactive silicone having a terminal silanol group, and wherein the condensate contains a siloxane bond derived from the silanol group.

A method for forming an article includes providing a sheet of material, optionally conditioning the sheet with a surface of a roller, forming the sheet to provide a web, and separating an article from the web to provide the article. An apparatus adapted to form the article from a sheet is provided.

A discharge member used for discharging contents accommodated in a container includes: an attachment part to be attached to the container; and a tubular part that is formed into a tubular shape, through which the contents from the container pass, the tubular part being provided with a tubular member in which a functional resin layer is disposed as an intermediate layer inside in a radial direction. The functional resin layer provided to the tubular member is disposed closer to the outer circumferential surface among the outer circumferential surface and the inner circumferential surface of the tubular member.

A method for manufacturing a closure constructed for being inserted and securely retained in a portal-forming neck of a product-retaining container is provided. Such method may include intimately combining a plurality of particles comprising cork and having a specified particle size distribution with a plastic material including one or more thermoplastic polymers, optionally in combination with other constituent(s) to form a composition, heating the composition to form a melt, extruding or molding a closure precursor from the melt to provide a specified water content range, and optionally cutting and/or finishing the closure precursor. A composition for use in manufacturing a closure for a product-retaining container includes a plurality of particles comprising cork and having a specified particle size distribution with a plastic material including one or more thermoplastic polymer, optionally in combination with other constituent(s). Methods for producing particulate material, cork composite material, and additional methods for producing closures are also provided.

A seal member is provided that may prevent fluids from leaking from a drinking bottle, such as a reusable water bottle. The seal member may be overmolded into a lid of the bottle such that the seal chemically and mechanically bonds to the lid. Overmolding the seal member eliminates gaps that could form between the seal and the lid, thus enhancing the cleanability of the seal member and the lid.
