Definitions

• the present invention relates to container lids and methods for manufacturing container lids.
• the present invention further relates to a use of container lids.
• lids provided with laminated liners to hermetically seal containers such as tins or jars to protect food products from deterioration, such as for example coffee, cocoa, tea powder and/or spread.
• Known laminated liners are commonly an assembly of several layers of different materials attached to each other and fixedly positioned inside these lids, adjacent to the lids’ internal surfaces.
• the lower layer is usually detachably connected to the rest of the layers of these liners.
• the lower layer may be glued or otherwise sealed to the perimeter of the upper rim of the neck of said containers, i.e. on their opening, in order to hermetically close and isolate from the atmosphere the food products inside.
• this lower layer is sealed on the containers’ aperture, it remains so when the lid is subsequently removed for the first time, while the remaining layers ofthe laminated liner are detached from the lower layer and retained in the container lid.
• the lower layer At first opening of the container, after having removed the lid (by unscrewing it for instance), the lower layer must then be removed from the neck of the container (peeled off) in order to access the containers.
• the lower layer of these known liners is commonly a metal layer (also called foil) which provides a barrier to the atmosphere, particularly to oxygen in air, which is responsible for oxidation processes and affects quality of the food products inside the containers, reducing their shelf life.
• the remaining layers of the liner usually consist of cardboard, adhesives layers, plastic layers and/or a combination of these different materials.
• These laminated liners are usually secured into the lid by applying a force to the liners in order to push them in place.
• This assembly step may lead to several quality issues which include damage to the liner, which undergoes stress when inserted into the lid, leading to delamination or loss of barrier properties due to scratches, cracks or faults that may occur, such as through excessive bending of the liner itself, during insertion into the lid, or when the lid is attached to the containers. These faults lead to sealing issues affecting the quality of the final food products.
• the known solutions usually show rigidity of the lid structure, preventing the lid structure from absorbing stresses or strains between the container neck and the lid during attachment to the container, and increasing material costs.
• Such rigidity of the lid can cause problems when attaching the lid to a container, such that any stresses or strains applied to the lid can cause detachment of the liner from the closure panel (or one or more layers thereof), which may make the lid unusable or jeopardise the hermetic sealing of the lid and container.
• known solutions include additional expensive manufacturing processes, and result in increased cost for quality inspections of the lids after the phase of inserting the liners in the lids.
• known liners and laminated liners need to be separated from the lid before recycling the lid, as the known liners comprise materials not compatible with recycling of the plastic lids.
• a container lid comprising: a closure panel having an inside surface and an outside surface; a container fastening portion; and a liner comprising one or more layers connected to the inside surface of the closure panel, wherein the liner or at least a lowermost layer of the liner is detachable from the closure panel, characterized in that said container lid comprises a resilient portion located between said closure panel and said fastening portion.
• said liner or said at least one lowermost layer is releasably connected to the closure panel by way of an adhesive.
• the liner or said at least one lowermost layer of said liner may comprise a metal layer.
• the metal layer may comprise an aluminium layer, which may comprise a polymer-coated aluminium layer.
• the liner or the at least lowermost layer of the liner may form a container opening sealing layer, arranged in use to seal an opening of a container to which the lid is connected.
• a container lid comprising a closure panel comprising: an inside surface and an outside surface; a container fastening portion; and a laminated liner comprising at least an upper layer and at least a lower layer, the upper layer being at least partially moulded into the inside surface of the closure panel and the lower layer of the laminated liner being releasably connected to the upper layer, characterised in that the container lid comprises a resilient portion located between the closure panel and the fastening portion.
• the lower layer is releasably connected to the upper layer by way of an adhesive layer.
• the adhesive layer may comprise an adhesive material selected from a lacquer, wax, polyolefin or a combination thereof.
• the lower layer may be a container opening sealing layer, arranged in use to seal an opening of a container to which the lid is connected.
• the lower layer comprises a metal layer.
• the metal layer may comprise an aluminium layer, which may comprise a polymer coated aluminium layer.
• the upper layer may comprise material selected from cartonboard, paper, a polymeric substrate, resin or a combination thereof.
• the polymeric substrate may comprise polyethylene, polypropylene, polyethylene terephthalate, and/or polylactic acid (PLA) and/or any combination thereof.
• the lower layer may comprise a plastic substrate which is incompatible with the plastic substrate of the upper layer.
• the lower layer has the same diameter and/or dimensions as the upper layer. More preferably, the lower layer has the same shape as the upper layer.
• the shape of the liner may match the shape of said closure panel.
• the shape of the liner may comprise a shape selected from a disc, circle, oval, triangle, trapezium, rectangle, square, parallelogram or pentagon.

It is believed this allows absorption of stresses and/or strains applied to the closure panel, fastening portion or lid per se, during manufacture and/or, attachment to the container, and/or detachment from the container.
• the rim comprises a double-walled rim comprising spaced apart first and second walls.
• Said spaced apart first and second walls may comprise a gap between them. At least part of the gap may protrude above the closure panel. It is believed that this configuration assists in absorbing stresses and strains within the lid, and/or between the container neck and the lid during manufacture (especially connection of the lid to the container) and use, and to mitigate delamination of the laminated liners prematurely.

• each lid (3) is checked by a control means (which may be visual, for example a camera, but any suitable control means may be used) to detect the presence of the liner in the lids (3).
• the lids (3) which pass the control are then sent to the packaging station;
• Stage 7 -the lids (3) are applied to containers (13) filled with food or beverage ingredients in order to be sealed.
• the rim of the opening of the container(s) is provided with an adhesive, which permanently seals the lower most layer (52) of the liner (5) to the rim, as the lids (3) are attached to the container (13).
• An alternative Stage 7 may be as follows:
• Stage 7 - those lids (3) are applied to containers (13) filled with food or beverage ingredients in order to be sealed.
• a heat-sealing process is applied to the external surface of the lids (3), permanently sealing the lower most layer (52) of the liner (5) to the rim (25) of the container (13).
