Abstract
A fluid-carrying bag (10) or container is provided as well as a method for forming such a bag. The bag (10) has identifiers (28a, 28b) indicating a status of the contents of the bag (10). To this end, a first layer and a second layer of preferably flexible material are sealed to form an interior (14) capable of holding a fluid. A flap (18) is provided wherein at least one hole (28a) may be punched through the flap (18) which is capable of detection by a sensor to indicate treatment of fluid within the interior (14) of the bag (10). One or more polarizing pieces (116a,b) may be provided between the fused layers (102, 104) in the flap (112) at a location through which the at least one hole (116a,b) is punched indicative of treatment of the fluid in the interior (108) of the bag (110).
Claims19
A fluid-carrying bag comprising:
- a first layer;
- a second layer sealed to the first layer to form an interior capable of holding a fluid wherein a portion of the first layer and the second layer is fused to form a flap wherein the flap has at least one hole punched therethrough capable of detection by a sensor to indicate treatment of the fluid in the interior;
- and
- a first polarizing piece between the fused layers in the flap at a location through which the at least one hole is punched.
A method for forming a bag having identifiers indicating a status of the bag, the method comprising the steps of:
- providing a first layer;
- providing a second layer sealed to the first layer to form an interior capable of holding a fluid;
- providing an area in which the first layer and the second layer are fused together;
- punching a hole through the area, the hole capable of sensing by a detector and providing an indication of the status of the bag:
- and
- providing a polarizing layer in the area in which the first layer and the second layer are fused together.
A container having an interior capable of carrying a fluid, the container comprising:
- a first flexible layer;
- a second flexible layer fused to the first flexible layer to form the interior;
- and
- a first polarizing piece constructed and arranged between the first flexible layer and the second flexible layer remote from the interior.
