383207000 | Line of weakness delineates substantially the entire tearing path | 50 |
20080247686 | Packaging With Improved Reclosable Opening - A packaging with improved reclosable opening is disclosed having a packaging body. The packaging body has an upper front main packaging sheet; a lower front main packaging sheet and a back main packaging sheet which are sealed together to form an edge-to-edge sealing. A reclosable opening is provided for inserting objects into the packaging. A diverting is means predisposed in such a manner and has a dimension sufficient to cover the reclosable opening to direct airflow away from the reclosable opening when there is an increase in internal air pressure. A weakened sealing is formed at a part of the edge-to-edge sealing wherein the weakened sealing ruptures when the increase in internal air pressure has build up to a critical point. When increased internal air pressure has build up to a critical point, the weakened sealing ruptures to allow air to vent through. The critical point is reached when the internal pressure is greater than external pressure to a sufficient extent to rupture the weakened sealing. The weakened sealing can be created by using a heat sealing temperature which is lower than the sealing temperature used for forming the rest of the edge-to-edge sealing, having a designated sealing area smaller than the sealing area of the rest of the edge-to-edge sealing, forming a notch on part of the edge-to-edge sealing, or disposing a film between the front and back main packaging sheets on part of the edge-to-edge sealing, wherein the film is made of a second material. | 10-09-2008 |
20080253701 | Method and Apparatus for Handling Perishable Items - A first container bag according to the present invention has top and bottom seals that are considered a lockup seal and an internal peel seal that will hold the gas and product in, but will also allow for ease of opening after removal of the top seal. This bag is such as that conventionally formed by use of VFFS technology, and includes the top and bottom end seals. However, the present invention provides additional features including a peel-away or otherwise separable seal, and a perforated segment. By tearing the bag at the perforated segment, the end seal may be bypassed, thus providing access to the internal separable “peel-away” seal. This configuration allows for a bag configuration which allows for the transportation of materials via the bag from a first, loading, location to a second, unloading, location, at which the items within the bag may be removed from the bag without the use of tools, and without tear-off discharge during the bag opening process. | 10-16-2008 |
