Four-flange child-resistant zipper and bag

Abstract:

The present disclosure relates to a plastic or polymeric container (100) with reclosable zippers or reclosures (10) which make the package child-resistant. In one typical embodiment, this is achieved by a zipper or reclosure (10) including a first profile (12) with a first lower interlocking element (28) and a first upper interlocking element (29), wherein the first profile (12) is severed through the first upper interlocking element (29) to form a lower first profile (12') and an upper first profile (12''). This severing forms at least one tab (18) extending from an upper edge of the lower first profile (12') and including a portion of the first upper interlocking element (29'). The second profile (14) includes a second web portion (30) with a second lower interlocking element (44) and a second upper interlocking element (46).
