<p>Methods and apparatus are disclosed for a lid for use in closing container openings on a range of containers having openings of different sizes. One method includes the steps of selecting an elastic material and forming the lid (10) out of the elastic material with a closure panel (12) and a gripping zone (14) along the periphery of the closure panel. The lid is made of a size which is smaller than the smallest size container opening so that the lid is resiliently stretched to be fitted over any of the container openings (34) for the resiliency of the lid to keep it engaged with any of the containers over such an opening. The size of the lid and the elasticity of the material are selected in relation to the anticipated sizes of the openings so that the resiliency of the material of the lid will be sufficient to provide a sealing engagement with any of the containers. The invention further provides a lid constructed in accordance with the above method.</p> |
