ABSTRACT:
A snap-on flexible lid for a container comprises a flat lid face and an annular, peripheral flange extending normally of the lid face to enclose and grip an annular lip of a container. The term "annular" is intended to include all closed loops, for example those of rectangular containers. The flange comprises spaced panels angled inwardly from the remainder of the flange to engage the underside of the container lip. This promotes retention of the lid on the container and permits a container where the flange is essentially free of circumferential tear lines, avoiding problems of lid pop-off, and undesired tearing of the circumferential tear lines in the event the container is dropped. The angled panels are defined between pairs of cutting apertures to permit the separation of the sections defining the panels by a pair of vertical cuts, for opening of the container.
