Abstract
The utility model provides the valve port moisture-proof construction of valve bag, and including the interior moisture-proof film flush-mounted in valve port, described moisture-proof film one end extends along valve port into valve bag.Due to moisture-proof film flexible relative, it can be closed at when valve port after valve bag fills powdery type material is closed flush-mounted in valve port in described and along the moisture-proof film that valve port extends into valve bag, effectively steam is stopped to enter in valve bag that powdery type material becomes damp and rotten in caused valve bag from valve port, and then avoids in valve bag powdery type material from becoming damp and rotten and cause damages to user.
Description
Technical field
The utility model relates to the valve port moisture-proof constructions of packaging bag technical field, especially valve bag.
Background technique
Valve bag is to be widely used as saving at present, transport, the packaging bag of sale kinds of goods material, especially powdery type material
Preservation, transport, in sale, valve bag is most commonly used, but requirement of the packaging bag of powdery type material to moisture resistance is compared
Strictly, the moisture-proof valve bag and on existing market, only bag body is moisture-proof and non-moistureproof at valve port, and the time has been grown or operated not
It is careful usually to cause to become damp and rotten powdery type material is from valve port in valve bag or even whole bag powdery type material cannot be normal
It uses, finally causes damages to user.
Utility model content
In view of the above shortcomings of the prior art, the utility model provides the valve port moisture-proof construction of valve bag, can prevent
Powdery type material becomes damp and rotten from the valve port of valve bag, and then avoids in valve bag powdery type material from becoming damp and rotten and make to user
At loss.
The utility model is realized in above-mentioned purpose:
The valve port moisture-proof construction of valve bag, including the interior moisture-proof film flush-mounted in valve port, described moisture-proof film one end is along valve
Mouth extends into valve bag.
Wherein, the moisture-proof film along valve port around formed with the matched moisture-proof film set of valve port, moisture-proof film set is to valve
One end imbricate extended in pocket.
Wherein, the moisture-proof film be upper and lower two panels, valve port be closed when moisture-proof film covering valve port fit closely one end to
Extend in valve bag.
Wherein, the valve port is folded by sheet material, and valve port is divided into moisture-proof film and is embedded in portion and the portion that is adhesively fixed, and bonding is solid
Determine the valve port installation place that portion's outer wall is adhesively fixed on valve bag, the moisture-proof film that moisture-proof film is inlaid in valve port is embedded in portion and valve port
Between bag inner wall.
Wherein, the valve port is folded by sheet material, and moisture-proof film one end is inlaid between valve port sheet material, and the other end is in valve
Between mouth and valve bag inner wall.
It is interior flush-mounted in valve port and along valve port to valve port the utility model has the beneficial effects that due to moisture-proof film flexible relative
Bag in extend moisture-proof film can after valve bag fills powdery type material valve port be closed when be closed at, effectively stop steam from
Valve port enters in valve bag that powdery type material becomes damp and rotten in caused valve bag, so avoid in valve bag powdery type material by
Tide goes bad to cause damages to user.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawing:
Fig. 1 is the valve port moisture-proof construction figure of the utility model；
Fig. 2 is the partial cross sectional views 1 of A in Fig. 1；
Fig. 3 is the partial cross sectional views 2 of A in Fig. 1.
In above-mentioned figure, 1. valve ports, 101. damp-proof membranes are embedded in portion, and 102. are adhesively fixed portion, and 2. moisture-proof films, 201. is anti-
Damp thin-film covering, 3. valve bags, 301. valve bag inner walls, 302. valve port installation places.
Specific embodiment
As shown in Figure 1, the valve port moisture-proof construction of valve bag, described moisture-proof including the interior moisture-proof film 2 flush-mounted in valve port 1
2 one end of film extends along valve port 1 into valve bag 3.It is described interior flush-mounted in valve port 1 and along valve due to 2 flexible relative of moisture-proof film
The moisture-proof film 2 that mouth 1 extends into valve bag 3 can be when valve port 1 be closed by material pressure after valve bag 3 fills powdery type material
It fits closely simultaneously and wraps valve port 1, steam is effectively stopped to enter in valve bag 3 powdery type in caused valve bag 3 from valve port 1
Material becomes damp and rotten, and then avoids in valve bag 3 powdery type material from becoming damp and rotten and cause damages to user.
As shown in Figure 1, the moisture-proof film 2 surround formation and the matched moisture-proof film 201 of valve port 1 along valve port 1, it is moisture-proof thin
One end imbricate that film 201 extends into valve bag 3 extends and imbricate after valve bag 3 fills powdery type material
Moisture-proof film 201 is fitted closely by material compressing in valve bag 3 and wraps valve port 1 together, more effectively stops steam from valve
Mouth 1, which enters in valve bag 3, causes powdery type material in valve bag 3 to make moist.
As shown in Figure 1, the moisture-proof film 2 is upper and lower two panels, moisture-proof film 2 covers valve port 1 and closely pastes when valve port 1 is closed
Unification end extends into valve bag 3, and upper and lower two panels moisture-proof film 2 is fitted closely by material compressing in valve bag 3 and covered together
Valve port 1 is wrapped up, more effectively stopping steam to enter in valve bag 3 from valve port 1 causes powdery type material in valve bag 3 to make moist.
As shown in Fig. 2, for convenience powdery type material it is filling when guarantee 1 intensity of valve port enough and moisture-proof film 2 not by
Damage or the moisture-proof function for shifting and influencing moisture-proof film 2, the valve port 1 are folded by sheet material, and valve port 1 divides for moisture-proof film
It is embedded in portion 101 and the portion 102 that is adhesively fixed, 102 outer wall of portion that is adhesively fixed is adhesively fixed on the valve port installation place 302 of valve bag 3, prevent
The moisture-proof film that damp film 2 is inlaid in valve port 1 is embedded between portion 101 and valve bag inner wall 301.
As shown in figure 3, for convenience powdery type material it is filling when guarantee 1 intensity of valve port enough and moisture-proof film 2 not by
Damage or the moisture-proof function for shifting and influencing moisture-proof film 2, the valve port 1 are folded by sheet material, described 2 one end of moisture-proof film
It is inlaid between 1 sheet material of valve port, one end is between valve port 1 and valve bag inner wall 301.
