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, additional methods for producing closures, and resulting closures are also provided.

A disposable drink-through dome lid for disposable drinking cups used in the sale of hot or cold beverages, the top of the lid elevated above the top of the beverage cup when in place. The lid's outer wall is elevated to form a drink ridge adapted to the user's lips for drinking through a generally oval-shaped drink-through orifice. Ideally, the drink-through orifice includes: a drink-through chamber having a drink flap capable of closing off a drink-through opening, thereby shielding against accidental spillage due to sloshing of the beverage while traveling; and a recessed orifice ridge on the interior side of the drink-through orifice, directs froth exiting the drink opening into a spill reservoir. A vent opening positioned near the lid's center and within a vent slot, collects and directs beverage exiting the vent into the spill reservoir.

A dispensing closure for a product container includes a plastic closure body having a top wall with a dispensing opening which is arranged in line with a dispensing passage of the container. The closure includes a self-closing valve embodied as a membrane made of a plastic foil. The membrane has a valve portion, which in use can assume an open position under influence of product pressure, and an attachment portion surrounding the valve portion. The attachment portion of the valve is sealed to an annular support surface integrally formed in the closure body along the periphery of the opening or being formed on a plastic annular insert part that is connected to the closure body along the periphery of the opening. The seal between the attachment portion and the support surface includes an annular groove and an inner annular seal zone adjoining the annular groove on a radial inner side.

A first aspect the present invention provides a thermally insulated container comprising a lid and a main body moulded from a single piece of expanded foam with outwardly tapering inner walls, necessitated by the moulding process. The container is arranged to be closed by the lid so that cool packs in the container extend from a base inside the main body to inside the lid, wherein the inner surface of the walls of the lid are tapered such that positioning the lid on the main body, with the cool packs arranged around the inner surfaces of the walls, causes the cool packs to be aligned so that they extend vertically, perpendicular to an inner surface of the base of the main body. This permits regular rectangular cool packs to be used to assist assembly and to provide a regular parallel sided space inside of the cool packs, in which a product to be shipped may be housed.

According to a second aspect of the invention there is provided a method of moulding such a container, wherein the provision or absence of an insert on the mould tool permits the container to have, or not to have, provision to accommodate an insulation panel layer, without altering the inner or outer dimensions of the container formed by the method.

The invention comprises a peelable membrane for resealably closing a metal end comprising an outer layer, a tacky layer, and a heat seal layer. The heat seal layer is permanently sealed to the metal end to cover at least one opening in the metal end. The tacky layer causes the peelable membrane to be resealable onto the metal end.
