    摘要: A tamper-evident plastic lid is welded to a plastic container at a welded portion and a detachable, replaceable lid portion is formed by tearing a frangible portion on the lid's skirt thereby leaving a torn tamper-evident, welded lid portion fixed to the container rim. The illustrated lid is a plug-fit lid which has a plug-shaped portion comprising a depressed central panel and an encircling, upstanding wall that engages an inner side of the container rim wall to retain the separated lid portion when it is replaced on the container. An energy director preferably in the form of an encircling bead on the lid initiates the softening of the plastic of the bead for welding with the plastic of the container rim. The preferred frangible portion is a reduced cross-sectional thickness web in a horizontally and radially extending skirt wall on the lid skirt overlying a horizontally and radially extending rim wall on the container rim. The frangible portion may be located radially inwardly of the welded portion. A pull tab may be provided on the replaceable lid portion to assist in initiating the fracturing of the thin frangible web. A pry slot may also be provided to aid in locating where and how to separate the replaceable lid portion from the welded portion which is permanently attached to the container.

    摘要: An oxygen scavenging polyolefin composition and methods of making thereof are described herein. In one approach, the composition includes a continuous non-polar polyolefin matrix having oxygen scavenging domains dispersed therein. The oxygen scavenging domains include an oxidizable polymer, a transition metal catalyst or salt thereof, and a catalytic promoter effective to bind with oxygen passing through the continuous non-polar polyolefin matrix. The oxygen scavenging domains forming a discrete polar region within the continuous non-polar polyolefin matrix. The composition further includes a polymeric compatibilizer having a polar moiety and a non-polar moiety and in amounts effective to uniformly disperse the polar oxygen scavenging domains in the continuous non-polar polyolefin matrix.
