Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
As in figure 2 it is shown, the valve bag that the present invention provides, including bag 100 and valve mouth structure, it is provided with by the bag of bag 100
Mouth 105 sides fold two the trapezoidal sealed pieces 101 and two rectangle sealed pieces 102 formed, and by two trapezoidal sealed pieces 101
Mutually overlap the bag mouth sealing member 104 constituting rectangle with two rectangle sealed pieces 102, wherein two trapezoidal sealed pieces 101 are respectively positioned on
The top of rectangle sealed piece 102, the feed end of the passage body 110 of described valve mouth structure is positioned at that bag 100 is outside, discharge end by
Insert between trapezoidal sealed piece 101 and rectangle sealed piece 102 in bag 100, described valve mouth structure passage body 110 only upper surface
It is adhesively fixed with the trapezoidal sealed piece 101 being positioned above, between described passage body 110 and the rectangle sealed piece 102 of correspondence
Formed and insert gap；Discharge end at the passage body 110 of described valve mouth structure is provided with one-body molded with passage body 110 and folds
The fixed layer 120 formed, described fixed layer 120 be positioned at corresponding rectangle sealed piece 102 lower section and with corresponding rectangle sealed piece 102
Inner surface be adhesively fixed.
Passage body 110 in use, for tubular；And when not using, for being flattened the rectangle formed by tubular.Described fixed layer
120 lower sections being positioned at corresponding rectangle sealed piece 102 are also adhesively fixed with the inner surface of corresponding rectangle sealed piece 102, described valve port
Described in structure channel body 110 only upper surface and two, trapezoidal sealed piece 101 is adhesively fixed, it is ensured that passage body 110 upper and lower surface all with
Bag 100 is fixing to be connected, and completes the installation of valve mouth structure；Meanwhile, at described passage body 110 and corresponding rectangle sealed piece 102
Between formed insert gap, therefore, after fill completes, by passage body 110 feed end along sealing fold line 112 to
Lower folding makes it seal, and then the feed end after fold closure is folded down along inserting fold line 113 and is inserted between insertion
Gap, it is possible to avoid the feed end of passage body 110 to be externally exposed, and by more preferable for the sealing effect of fold closure；Finally, pass through
Feed end after glue coating ensures fold closure connects with between passage body 110 and the rectangle sealed piece 102 of correspondence of corresponding part
Connect stablizes, therefore, it is possible to exempt to cause passage body 110 damaged in use, transportation.
The width of passage body 110 can be less than or equal to the thickness of bag 100, it is preferred that the width of described passage body 110 with
The thickness of bag 100 is consistent, and described fixed layer 120 length is consistent with the width of passage body 110.Now, passage body 110
Feed end opening is maximum, it is possible to facilitate the fill of material；Operations area increases simultaneously, it is possible to facilitate bonding operation.
Further, owing to the width of passage body 110 and the length of fixed layer 120 are consistent with the thickness of bag 100, therefore,
In order to improve the sealing of valve bag further, between described passage body 110 upper surface and the trapezoidal sealed piece 101 above it
Bonding plane is through the width of passage body 110；Bonding plane between described fixed layer 122 and passage body 110 surface runs through
Width in passage body 110.
Further, the feed end of described passage body 110 is provided with along passage body 110 passage body reinforced structure circumferentially.
The setting of passage body reinforced structure, is the intensity in order to improve passage body 110 feed end, right with feed mechanism when facilitating fill
Connect, avoid the breakage of passage body 110 feed end simultaneously.
Above-mentioned passage body reinforced structure can be adhesively fixed on passage body 110 feed end circumference paper ring, as Fig. 1,2,3,
In embodiment shown in 4, concrete, described passage body reinforced structure is by one-body molded with passage body 110 and turn down and formed
Reinforcing ring 111 is constituted, and constitutes bilayer knot at feed end in described reinforcing ring 111 is arranged at passage body 110 and with passage body 110
Structure.Passage body reinforced structure is one-body molded with passage body 110, it is simple to its manufacture, be arranged on inside discharge end avoid use time
Damage.Passage body reinforced structure can also be arranged at outside passage body 110 feed end, and constitutes at feed end with passage body 110
Double-decker.
The valve mouth structure of above-mentioned valve bag, the discharge end at described passage body 110 is provided with fixed layer 120, described fixed layer 120
It is connected and one-body molded with the side, side of passage body 110, and is constituted this side by the edge of passage body 110 corresponding side surface discharge end
Folding line 121 between face and fixed layer 120.
In order to further facilitate manufacture, reducing operation, described fixed layer 120 is arranged in pairs, two fixed layer 120 and passage body 110
Side, both sides one_to_one corresponding, and respectively with corresponding passage body 110 side be connected.Only need to be by a rectangle material phase during manufacture
To the bonding formation in both sides passage body 110, then after the stamping-out of passage body 110 one end fold formed, easily manufactured.
Above-mentioned valve mouth structure, as it is shown in figure 1, fixed layer 120 can be protected as position limiting structure when valve mouth structure and bag assemble
Location between card valve mouth structure and bag 100；Simultaneously as the width of passage body 110 and the length of fixed layer 120 and bag
The thickness of body 100 is consistent, and therefore positioning precision is high, and the concordance of valve bag is good, it is possible to facilitate final fill operations.
