Patent name for a bubble-like sealing device for conveniently opening a sealed package Patent applicant POPEX LLC Principal applicant address William S. Perel, California inventor; Neil S. Hayden (patent) No. 03820677.3 Date of application 2003.08.21 Certification date Approval Notice No. 1678501 Auditing announcement date 2005.10.05 Documentation CD No. D0540 Main classification number B65D33/00 Classification No. B65D33/00 Division Original application No. 2002.9.19 US 10/246,893 An easy-to-open storage package (10) has a closure material (10M) for forming a storage chamber (10C) inside the package for accommodating stored items (10A). The chamber access area (12A) is proximate to the edge (12E) of the package, providing access to the chamber and access to stored items. A band-like seal (14) formed by the upper thin layer (14U) and the lower thin layer (14L) extends along the entry region to enclose the ruptured bubble portion (16). The band seal has an inboard seal (14I) located between the bubble and the chamber and an outboard seal (14O) located between the bubble and the package edge (12E). Under the influence of external pressure exerted by the consumer, the bubble can expand to open the package. As the bubble bursts, the opposing pair of release sheets, ie, the upper release sheet (16U) and the lower release sheet (16L), are formed by relatively thin layers in the outer seal along the edge notch. These small initial release sheets are gripped by the consumer and manually peeled open to begin opening the strip seal. Slaves 1. A blister seal for conveniently opening a storage package, comprising: a closure material forming a chamber for accommodating stored items in the package; a chamber access area near the edge of the package; A strip-shaped seal formed by a relatively thin layer of a sealing material pressed into a sealed-bonded state and extending along the entry region; a bursty bubble closed within the strip-shaped seal between the relatively thin layers An inner seal located between the bubble and the chamber within the band seal, formed by the relatively thin layer; within the band seal located at the edge of the bubble and the device An outer sealing portion between the two, which is formed by the relatively thin layer; under the pressure applied, the bubble expands towards the edge of the device to separate the relatively thin layer until the bubble portion Cracking at the edge, creating an edge gap in the outer seal; and opposing peel sheets formed by relatively thin layers of the outer seal along the edge of the bubble as they break, the peel sheets being peeled apart, The relatively thin layer is separated so as to open the band seal.
