Abstract
The utility model relates to a sealed packing bag with automatic exhaust, which belongs to the plastic jointing type and the packing type. The sealed packing bag with automatic exhaust is composed of a plastic bag or a paper bag [4], a sealed window [2] which is provided with a vent hole [3] and a reinforced layer [1]. After the packing bag of the utility model is sealed, the residual gas in the packing bag can be automatically discharged. The sealed packing bag with automatic exhaust not only can ensure the articles in the packing bag to be free from the erosion of the outside moist and the gas but also can prevent the fracture phenomenon of the bag which is squeezed in the transportation process. The utility model has the advantages of easy fabrication, low cost and convenient operation. The sealed packing bag with automatic exhaust is the good packing bag for the cement, the chemical fertilizer, the sugar, the chemical industry powder, etc.
Description
The utility model is a kind of self-bleeding sealing bags that engages class and packaging group about plastics.
Known sealing bags is that material is made by full paper, overall plastic or paper is compound etc., see that the Jilin daily paper " adopted the new material up-to-date technology to improve commodity packaging " March 19, this packaging bag is because of no exhaust sealing hole, often after the sack sealing, still leave certain gas in the bag in occupation of article remaining space in addition.Like this, because the existence of the gas in the packaging bag, the one, may make the article corrosion; The 2nd, in transportation carrying, because extruding, sack usually is bursting at the collision and causes unnecessary loss.
The purpose of this invention is to provide the self-bleeding sealing bags of a kind of energy, after making the packaging bag sealing, can discharge the gas in the bag automatically, guarantee that promptly bag inner packing article are not subjected to the erosion of extraneous humidity and gas, sack is burst in the extruding in preventing from again to carry again.
The utility model is provided with a self-bleeding hermetyic window of energy (2) as shown in the figure at least on plastic bag or paper bag (4), so that after the packaging bag sealing, can discharge the gas in the bag automatically.Hermetyic window (2) is added by two layers of plastic film that has a deflation hole (3) or quires at least and forms, and will seal around the hermetyic window (2).Every layer of plastic film of hermetyic window (2) or the deflation hole (3) between the paper certain distance that staggers mutually, the purposes of neglecting bag greatly of deflation hole (3) is different and different with specification, in order to make packaging bag durable in use, the outermost of packaging bag can be shaped on consolidating layer (1), and consolidating layer (1) adopts materials such as fibrous glass, chemical fibre, fiber crops, cotton spinning thing or craft paper.
The utility model manufacturing is simple, with low cost, easy to use, effect is obvious.It is the good packaging bag of article such as cement, chemical fertilizer, sugar, chemical industry pulvis.
Most preferred embodiment of the present utility model as shown in the figure, (1) is consolidating layer, (2) are hermetyic window, (3) are deflation hole, (4) are plastic bag or paper bag.
Claims (4)
1, a kind of self-bleeding sealing bags, be that material is made by full paper, overall plastic or paper is compound etc., it is characterized in that being provided with at least in the packaging bag a self-bleeding hermetyic window [2], hermetyic window [2] is added by two layers of plastic film that has a deflation hole [3] or quires at least and forms sealed air-tight around the hermetyic window [2].
2, by the described packaging bag of claim 1, every layer the deflation hole (3) that it is characterized in that hermetyic window (2) certain distance that staggers mutually, the purposes of neglecting bag greatly of deflation hole (3) is different and different with specification.
