It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example one
Referring to fig. 1-4, the present embodiment includes a bag body 1, a top seal 2 and a bottom seal 3 are respectively disposed at the upper end and the lower end of the bag body 1, a valve port 4 is disposed between the top seal 2 and the bag body 1, the valve port 4 is divided into a first channel 41 and a second channel 42, one end of the valve port 4 extending into the bag body 1 is the second channel 42, an inclined piece 5 is disposed between the first channel 41 and the second channel 42, a material passing opening 51 is formed on the inclined piece 5, the inclined piece 5 is provided with a shielding piece 6 matched with the material passing opening 51, the shielding piece 6 is fixedly connected with the inclined piece 5, the width of the shielding piece 6 is greater than the aperture of the material passing opening 51, the shielding piece 6 can completely cover the material passing opening 51 when turning to the material passing opening 51, and the shielding piece 6 can open the material passing; the shielding sheet 6 is arranged in the second passage 42, more than two laminated sheets 7 are arranged in the second passage 42, an overlapping area 8 is arranged between two adjacent laminated sheets 7, and two ends of each laminated sheet 7 are fixedly connected with the upper end surface and the lower end surface of the second passage 42 respectively.
The upper end of the inclined plate 5 is arranged close to the first channel 41, the lower end of the inclined plate 5 is arranged close to the second channel 42, the shielding plate 6 is arranged between the material passing opening 51 and the lamination 7, and the shielding plate 6 is arranged between the material passing opening 51 and the lower end face of the valve opening 4. When the filling nozzle passes through the material passing opening 51, if the shielding piece 6 covers the material passing opening 51, the shielding piece 6 can be easily pushed to enter the bag, and the design does not prevent the filling nozzle from extending into the bag. When the material is filled, the valve port 4 is closed to form a sealing structure, and the shielding piece 6 covers the material passing port 51 or is attached to the inclined piece 5. When the cover is covered on the material passing opening 51, the material can be effectively prevented from entering the material passing opening 51, and the sealing effect is good; when the material is attached to the inclined plate 5, if the material flows outwards along the second channel 42, the material enters the gap between the shielding plate 6 and the inclined plate 5, the shielding plate 6 can also effectively prevent the material from entering the material passing opening 51, and the sealing effect of the shielding plate 6 in this state is good.
The folding line 73 is arranged on the lamination 7, the lamination 7 is divided into a first folding sheet 71 and a second folding sheet 72 along the folding line 73, the first folding sheet 71 and the second folding sheet 72 are symmetrically arranged along the folding line 73, and the first folding sheet 71 and the second folding sheet 72 are fixedly connected with the upper end and the lower end of the second channel 42 respectively. When the bag 1 is filled with material, the material will abut against the laminate 7, and this design allows the first flap 71 and the second flap 72 to completely overlap, thereby providing a better seal for the laminate 7. With the second channel 42 closed, it is more difficult for material to enter between the first flap 71 and the second channel 42 and between the second flap 72 and the second channel 42, while it is more difficult for material flowing between the first flap 71 and the second channel 42 and between the second flap 72 and the second channel 42 to flow laterally into the overlap region 8. The second channel 42 and the overlapping area 8 make the material flow direction different, and the sealing performance is better.
The lamination 7 is made of elastic material, so that the filling nozzle can conveniently penetrate through the overlapping area 8 along the lamination 7 and enter the bag body 1.
The upper end face of the second channel 42 is fixedly connected with the top seal 2, and the arrangement can effectively ensure the stable structure of the lamination 7, so that the lamination 7 can be smoothly overlapped together after being opened.
The lower end face of the second channel 42 is provided with a forming layer, the forming layer is made of paper, the paper is not prone to wrinkling, and the valve port 4 can be ensured to be opened and closed completely, so that the first folding sheet 71 and the second folding sheet 72 can be completely folded together.
Example two

the upper end of the inclined plate 5 is arranged close to the second channel 42, the lower end of the inclined plate 5 is arranged close to the first channel 41, the shielding plate 6 is arranged between the material passing opening 51 and the lamination 7, and the shielding plate 6 is arranged between the material passing opening 51 and the upper end face of the valve opening 4. When the filling nozzle passes through the material passing hole 51, the shielding sheet 6 can be easily pushed away to enter the bag, and the design does not prevent the filling nozzle from extending into the bag. When the material is filled, the valve port 4 is closed to form a sealing structure, and the shielding piece 6 covers the material passing port 51 or is attached to the inclined piece 5. When the cover is covered on the material passing opening 51, the material can be effectively prevented from entering the material passing opening 51, and the sealing effect is good; when the material is attached to the inclined plate 5, if the material flows outwards along the second channel 42, the material passing opening 51 is behind the shielding plate 6, the shielding plate 6 can also effectively prevent the material from entering the material passing opening 51, and the sealing effect of the shielding plate 6 below the body is good.
In the utility model, the valve port 4 is opened, the filling nozzle passes through the material passing port 51 and then passes through the overlapping area 8 to extend into the bag body 1, when the bag body 1 is filled with materials, the lower end surface of the valve port 4 is pressed against the upper end surface of the valve port 4 to form a sealing structure; the sealing structure formed by the second channel 42 and the overlapping area 8 of the lamination 7 are mutually matched to prevent the material from flowing out of the bag from different directions, the sealing effect is good, the shielding piece 6 is arranged, the material can be effectively prevented from entering the material passing opening 51, and the sealing performance of the valve port 4 is further improved. The sealing structure of the first channel 41 can improve the sealing performance of the valve port 4. The utility model discloses simple structure, quadruple seal structure has improved the sealed effect of valve port 4.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
