摘要： PROBLEM TO BE SOLVED: To provide a heat-shrinkable packaging receptacle which is easy to manufacture and is provided with a seal which is easy to peel with a hand, and with a high-strength end seal resistant to breakdown. SOLUTION: The individual end-sealed packaging receptacle is formed, like a bag, from a heat-shrinkable film sheet, having a first edge and an opposing second edge. This packaging receptacle includes a first seal bonding the first edge and the second edge to define a tube member having a first bag wall, second bag wall, first and second opposing lay-flat bag edges, an end and an open mouth. The packaging receptacle includes a second seal through the first and second bag edges, extending laterally across the width of both the first and second bag walls and thereby closing the end. Preferably, at least one of the first and second seals is a peelable seal. The first seal may be a lap seal, a fin seal, a butt-seal, or a seal strip. A method of forming an individual, end-sealed, heat-shrinkable packaging receptacle is also disclosed. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： The present disclosure is concerned with flexible reclosable containers which have a one way valve system which provides a means to vent fluids, from the interior of container when the repeatedly reclosable closure member, is in a closed state. It is also concerned with a process for creating such a valve system using a seal bar with voids to create a channel which passes behind the closure member. The valve system which is disclosed comprises a central passageway which connects port which communicates with the environment to a port which communicates with the interior of the package. Also disclosed is the concept of using this valve system with a readily removable hermetic seal such that the port intended to communicate the environment initially communicates with the headspace between the reclosable closure member and the hermetic seal but subsequently does communicate with the environment when the hermetic seal is removed.
