Disposable air outlet channel for a vacuum compression bag and a vacuum compression bag with a disposable air outlet channel

摘要

Disclosed are a unidirectional air outlet channel for a vacuum compression bag and a vacuum compression bag with such a unidirectional air outlet channel. The unidirectional air outlet channel (6) is located in the vacuum compression pocket and is arranged between a front pocket piece (1) and a first underside (31) and / or between a rear pocket piece (2) and a second underside (32), the unidirectional air outlet channel (6) an air inlet (60) and a horizontal air path (61), an inclined air path (62) and a vertical air path (63), which are connected in series and connected to one another, and an air outlet (64), one end of which is horizontal air path (61) is the air inlet (60) connected to the interior of the bag body, and the other end is connected to the inclined air path (62), the lower end of the vertical air path (63) connected to the air outlet (64 ) and the upper end is connected to the inclined airway (62), whereby at least two turning points are formed at the points where the horizontal airway (61) with the ge inclined airway (62) or the inclined airway (62) is connected to the vertical airway (63). The unidirectional air discharge duct has a simple configuration, a fast discharge speed and a strong tightness after the discharge of air.
