<p>A closure for a container having an opening, comprising a resilient mass of interlocked and/or otherwise associated synthetic and/or natural fibres having a density of 0.18 to 2.00 g/cm3, wherein the closure is of suitable shape and density to enable the closure to be sealingly inserted into the opening of said container.The term "fibres" refers to materials that may be formed into a yarn, textile, carpet or the like. The fibres, or a portion of the fibres, may also be present in the form of bonded "felted yarns" or "felted slivers". The closures may further comprise one or more additives which may be added, for example, to vary the resilience or density of the fibre mass; to vary the sealing properties of the closure; and/or assist insertion or extraction of the closure. The additives may also be added in order to isolate the fibre mass from the contents of the container. A method of manufacturing the closure is also claimed.</p> |
