Abstract
A tamper evident closure member having tamper-evident breakaway strips and correctly spaced reinforced pull-tabs allowing a user to remove the closure member and separate the breakaway strips from a container by lifting the closure member at one of the pull-tabs. The closure member is configured such that the removal and separation happen in a single motion. Moreover, the tamper evident closure member includes engaging walls having a different angle than that of a rim of a container, thereby assisting in complete removal of the breakaway strips during the single motion separation. The closure member also includes vertical indicators providing enhanced tamper resistance.
Claims18
A closure member comprising:
- a center section configured to cover a container;
- a skirt surrounding the center section;
- a plurality of non-continuous breakaway strips;
- a frangible web for attaching the skirt to the breakaway strips;
- a plurality of pull-tabs formed on the skirt, wherein each pull-tab is positioned between adjacent breakaway strips;
- and
- at least one protruding edge on each of the breakaway strips, the protruding edge configured to provide single motion separation of the breakaway strips from the skirt when one of the pull-tabs is lifted upwardly.
A reclosable container comprising:
- a container having an inverted U-shaped annular rim terminating at a tip;
- and
- a lid having
- a center section,
- a skirt formed at the periphery of the center section and configured to engage the rim of the container, and
- a plurality of strips frangibly attached to the skirt, wherein each strip includes an inner edge configured to engage the tip of the rim such that a single motion separates the skirt from the strips and the lid from the container.
A closure member comprising:
- a cover section configured to cover an open end of a container;
- and
- a skirt surrounding the cover section and having a plurality of pull-tabs circumferentially spaced around the periphery of the skirt, each pull-tab being of a thicker cross section than that of the skirt and each pull-tab having at least one protrusion configured to engage an edge of an a rim of a container so as to attach the closure member to the container.
A closure member comprising:
- a center section configured to cover an open end of a container, the open end of the container terminating in an outermost tip;
- a skirt surrounding the center section and having an inverted U-shaped cross section, the inverted U-shaped cross section having a first wall connected to the center section and a second wall opposite the first wall;
- at least one pull-tab attached the second wall;
- and
- at least one breakaway strip adjacently attached to the pull-tab via vertical indicators and attached to the skirt via a perforated web, the breakaway strip having a first protrusion configured to engage the container at the outermost tip such that the vertical indicators, the perforated web, and the breakaway strips form a tamper evidencing mechanism,
- wherein the closure member further comprises three pull-tabs, each pull-tab having a pull-tab protrusion substantially similar to the first protrusion on the breakaway strip.
A closure member comprising:
- a center section configured to cover an open end of a container;
- a skirt surrounding the center section;
- a plurality of breakaway strips configured to prevent tampering;
- a plurality of weakened sections, each weakened section frangibly connecting at least a portion of each the breakaway strip to the skirt;
- and
- at least one pull-tab fixedly attached to the skirt and frangibly attached between breakaway strips such that a user lifting on the pull-tab separates the closure member from the container in a single motion.
