ABSTRACT:
A plastic container and a one-piece molded plastic lid for the container are provided with a tamper resistant, hermetic seal. The lid includes a top wall and a surrounding depending sidewall. The sidewall has a thin upper web upper portion and a relatively thick lower skirt portion. The mouth of the container includes a circumferential lip. The thin web deforms as the lid is snap fitted onto the container. The deformable web stretches into close conformity and sealing engagement with the lip of the container, the lower skirt region of the lid maintaining the web in a tightly constricted configuration about the lip. The skirt is sealed to the sidewall of the plastic container by a circumferential sealing strip formed integrally with and extending downwardly from the lower edge of the lid skirt. The lower portion of the sealing strip is attached directly to the sidewall of the plastic container by adhesive or welding. The connections between the sealing strip and both the container and the lower edge of the skirt of the lid are narrow to define weakened tear lines. A portion of the tear strip is formed to protrude and define a starter tab which may be gripped easily by the user to initiate tearing of the tear strip.
