Abstract: An easily opened storage package 10 has enclosure material 10M forming storage chamber 10C within the package containing stored article 10A. Chamber access region 12A proximate edge 12E of the package, provides entrance into the chamber and access to the stored article. Band seal 14 formed by upper lamina 14U and lower lamina 14L extends along the access region, enclosing breaching bubble 16. The band seal has inner seal portion 14I between the bubble and the chamber, and outer seal portion 14O between the bubble and edge 12E of the package.

Abstract: A flexible container is provided for the storage and administration of medical solutions. The container incorporates a transparent front sheet made from a planar layer of a polymer and an opposing rear sheet. The rear sheet is made from a planar laminate layer. The front and rear sheets are sealed together along a common peripheral edge to form a volume enclosure. The volume enclosure is constructed of materials having high oxygen and moisture barrier properties which allows the container thermoplastic to be stored for extended periods of time without degrading the contents. The volume enclosure is then inflated with a pressurized gas to permanently stretch the front and rear sheets outwardly and to thereby increase the volume capacity of the container. An alternative embodiment of the container incorporates multiple compartments, separated by peelable seals, for containing a diluent and a medicament.

Abstract: A reclosable packaging having a slider/zipper assembly, a header and a tamper-evident feature which undergoes a tangible change when the slider is moved relative to the header for the first time. The tamper-evident feature comprises a layer of sticky or adhesive material placed between a surface of the header and an opposing surface of the slider, thus forming a seal. The material must have a peel strength or resistance to rupture sufficient to resist an initial movement of the slider along the zipper. If the slider is stuck or adhered to the header, this indicates that the package or bag has not been tampered with, i.e., previously opened. When sufficient force is applied, the seal can be broken, allowing the slider to move relative to the header along the zipper in the direction of opening. Once broken, the seal cannot be restored by simply returning the slider to its original position and pressing the slider against the sticky or adhesive material.
