20100119180 | PAPER VALVE SACK WITH INNER CATCH - A description is given of a paper valve bag with an inner panel which is located at the paper-bag end which is located opposite the paper-bag end with valve, and, on its surface which is directed toward the sack interior, the inner panel has an opening aid which has a higher modulus of elasticity than the inner panel. The opening aid, which may be a tear-open strip or a tear-open thread, projects beyond the inner panel at at least one surface-area end of the latter. Such paper valve bags are used for fine-grain, pulverulent and/or free-flowing materials, in particular ready-to-use mortar. | 05-13-2010 |
20110293207 | EASY OPEN BAG - An easy open bag and method for making the same. A film is fed into a jaw assembly comprising a first seal jaw comprising a blade gap and a second seal jaw comprising a removable insert. The removable insert comprises a blade pin. When the first and second seal jaws are mated, a notch is formed. The film also comprises a score line in the outer layer. Upon tearing the notch the tear propagates along the score line. Thus, the package can be easily opened by initiating a tear at a tear notch. | 12-01-2011 |
20130272630 | Packaging Receptacle For Making Packaging Article Exhibiting Combination of Linear Tear and Directional Curl - A packaging receptacle, made from a flexible film, has a first side sealed to a second side, a top edge and an open top, an interior chamber, and a tear initiator. A product is placed in the internal chamber within the packaging receptacle, and the receptacle sealed closed. The flexible film has a linear tear property and an imbalanced internal stress so that the film exhibits a linear tear property in combination with the torn edges curling outwardly and away from the interior chamber within the packaging article. The packaging receptacle is particularly suited for the packaging of medical products to be sterilized while in the package. Also disclosed is a manually-openable packaged product, a process for preparing and transferring a product, and a process of opening a packaged product made from a packaging receptacle. | 10-17-2013 |

20100278462 | Package With One or More Access Points For Breaking One or More Seals and Accessing the Contents of the Package - An easy to open package is described. The package includes a sealed compartment having a tab region. The tab region is formed by connecting together a first panel to a second panel. Within the tab region, however, are a pair of opposing peel tabs. The peel tabs comprise an area within the tab region where the first panel is not sealed to the second panel. The peel tabs extend from the tab region to an edge of the package. In this manner, a user can peel apart the peel tabs to separate the first panel from the second panel and open the sealed compartment. In one embodiment, at least one of the peel tabs can be coated with a material to prevent the first panel from sealing to the second panel. | 11-04-2010 |

20130209003 | BAG PACKAGING - A pouch-type packaging for packaging pourable contents and having a front wall and rear wall made from at least one flexible packaging film is such that the front wall and the rear wall are joined together via a sealing seam. The sealing seam is extended in a region bordering a sealing zone oriented away from the sealing edge with a free end furthest removed from the sealing edge. The front wall of the pouch exhibits an outer layer on the side directed towards the outside of the pouch. The outer layer and the part of the front wall of the pouch lying under the outer layer delimit a outlet zone for the contents in an area which encloses the free end of the sealing zone and extends to an edge of the sealing edge. The application of pressure produces a tear in the part of the front wall of the pouch lying under the outer layer in the region of the free end of the sealing zone and the contents enter the outlet zone and emerge from the pouch at the edge of the sealing edge. | 08-15-2013 |

20150314924 | Film Bag for Storing a Fluid and Device for providing a Fluid - A film bag for storing a fluid, in particular a reagent or an auxiliary agent for a biochemical analysis method, includes a film, a seam, and an irreversibly destructible predetermined breaking point. The film is impermeable to the fluid and constituents of the fluid. The seam is formed in a fluid-tight manner between a first sub-region of the film and a second sub-region of the film and forms the film into a fluid-tight bag for accommodating the fluid. The bag is configured to be arranged in a chamber of a device that provides a fluid for a biochemical evaluating unit. The predetermined breaking point is formed from the film and is fluid-tight when a fluid pressure in the film bag is below a limit. The predetermined breaking point is destroyed when the fluid pressure is above the limit. | 11-05-2015 |
