| 摘要 |
The invention concerns a bag comprising two generally parallel sheets (16, 18) forming the bag main walls, matching closing sections (20, 22) respectively fixed on said sheets and a slider (50) actuating the sections (20, 22) for closing and opening. The invention is characterised in that it further comprises, parallel to the closing sections (20, 22), between said sheets (16, 18) and at the bag opening (12), additional raised relief means (100) designed to ensure tightness by forming a barrier between the sheets (16, 18), when the bag is closed, said additional raised relief means (100) being placed opposite the slider (50) flanks (52, 54) to be urged towards their sealing position by the slider (50) when the slider is moved towards the sealing position. |
