Abstract
A fluid drainage bag comprises a sealed bag body and a tab member integrally formed on the bag body. When the tab member is laterally pulled away from the bag body by the attendant, the bag body tears to form a permanent outlet opening through which fluid may be drained from the bag body.
Claims5
A fluid drainage bag comprising:
- a bag body including a top edge and an adjoining side edge, said top edge and said adjoining side edge together defining a corner section of said bag body;
- an internal fluid chamber within said bag body having an inlet port and an outlet port;
- an outlet extension portion communicating with said outlet port and having a sealed end portion spaced from said outlet port, said outlet extension portion located within said corner section of said bag body, the material of said outlet extension portion in the area of said outlet port is not weakened by a score line or similar means;
- a seam in said corner section defining a preformed section of a tear line extending from said top edge of said bag body toward said outlet extension portion;
- a tab member formed intermediate said seam and said top edge of said bag body, said tear tab adapted when initially pulled laterally toward said outlet extension portion to cause the bag body to tear along said preformed tear seam and further adapted when pulled further to cause the bag body to tear across the previously unweakened material of said outlet extension portion to thereby create an opening at said outlet port to facilitate drainage of fluid from said internal fluid chamber within said bag body.

A fluid drainage bag comprising:
- a bag body having an internal fluid chamber therein, said internal chamber having an inlet port and an outlet port;
- an outlet extension portion communicating with said outlet port and having a sealed end portion spaced from said outlet port, the material of said outlet extension portion in the area of said outlet port is not weakened by a score line or similar means;
- a tear tab having a free edge formed integral with one edge of said outlet extension portion, a seam extending along the juncture between said tear tab and said outlet extension portion, said free edge of said tear tab intersecting said seam at a stress point, said seam adjacent said stress point being reinforced so that when said tear tab is pulled laterally toward said outlet extension portion it will cause the bag body to tear across the previously unweakened material of said outlet extension portion to thereby create an opening at said outlet port to facilitate drainage of fluid from said internal fluid chamber within said bag body.
