  • Patent number: 11246973
    Abstract: A drainage bag is provided for a thermal control unit adapted to deliver temperature-controlled liquid to a patient in order to control the patient's temperature. The drainage bag is used to hold and transport the liquid when the liquid inside the thermal control unit is changed. The drainage bag includes a bottom layer, a top layer sealed thereto, and a float secured to the top layer that is positioned adjacent an opening in the top layer. As the liquid from the thermal control unit drains into the opening in the top layer, the liquid lifts the float and the float lifts the top layer of the bag. The bag thereby expands its volume to accommodate the liquid from the thermal control unit. The bag may further be designed to be carried without sealing the opening and without spilling the liquid. A method for using the bag is also disclosed.

    Abstract: 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.

    Abstract: A flexible packaging structure has built-in opening features in a laminate with a first structure adhesively joined to a second structure. A tear area is formed by laser ablation of the laminate along a junction between the first and second portions preferably prior to assembling the laminate into the package. Laser ablation begins at the center of the tear area and progressively moves the laser in a direction radially outward from the center of the tear area. During assembly of the package, a seal is formed between end portions of the first and second portions of the laminate. A score line and a sealant reduction area are also introduced to the package to facilitate opening. The package is opened by pulling the seal near the tear area in a direction along the score line until the contents of the package are accessible.
