Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. 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, one end of the valve port 4 extending into the bag body 1 is an extending end 41, two or more laminated sheets 6 are disposed at the extending end 41, an overlapping area 7 is disposed between the two laminated sheets 6, and the overlapping area 7 is disposed along the height direction of the extending end 41.

The laminated sheet 6 is arranged in the extending end 41, the laminated sheet 6 is fixedly connected with the extending end 41, and the bag body 1 is communicated with the outside through the overlapping area 7.

The folding sheet 6 is provided with a folding line 63, the folding sheet 6 is divided into a first folding sheet 61 and a second folding sheet 62 along the folding line 63, the first folding sheet 61 and the second folding sheet 62 are symmetrically arranged along the folding line 63, and the first folding sheet 61 and the second folding sheet 62 are fixedly connected with the upper end and the lower end of the valve port 4 respectively. When the bag 1 is filled with material, the material will abut against the laminate 6, and this design allows the first flap 61 and the second flap 62 to completely overlap, thereby providing a better seal for the laminate 6. After the extending end 41 is closed, the material is hard to enter between the first flap 61 and the extending end 41 and between the second flap 62 and the extending end 41, and the material flow between the first flap 61 and the extending end 41 and between the second flap 62 and the extending end 41 is more difficult to flow transversely into the overlapping area 7. The second channel and the overlapping area 7 make the material flow direction different, and the sealing performance is better.

The lamination 6 is made of elastic material, so that the filling nozzle can conveniently open the lamination 6 to enter the bag body 1.

The upper end face of the valve port 4 is fixedly connected with the top seal 2, and the arrangement can effectively ensure the stable structure of the lamination 6, so that the lamination 6 can be smoothly overlapped together after being opened.

The lower terminal surface of valve port 4 is equipped with the shaping layer, and the shaping layer is the paper, and the difficult fold phenomenon that takes place of paper can guarantee that valve port 4 can open completely and closed to guarantee that first folded piece 61 and second folded piece 62 can fold together completely, this setting does benefit to the sealed effect of guaranteeing lamination 6.

In this embodiment, the lamination 6 is plural, and an overlapping area 7 is provided between two adjacent laminations 6. The filling nozzle can enter the bag through any one of the overlapping areas 7, and the design is favorable for the smooth entering of the filling nozzle into the bag.

Example two

This embodiment is substantially the same as the first embodiment, except that:

referring to fig. 5, the laminated sheet 6 is disposed outside the extending end 41, and the embodiment further includes two side sheets 5, the two side sheets 5 are respectively disposed at two sides of the valve port 4, more than two laminated sheets 6 are disposed between the two side sheets 5, and two ends of the laminated sheet 6 are respectively fixedly connected with the upper end and the lower end of the extending end 41.

The side piece 5 is made of elastic material, so that the side piece can be opened and closed together with the valve port 4, and the opening and the folding of the lamination 6 are facilitated. In the present embodiment, the laminate 6 and the side sheet 5 are both PE films.

In the utility model, the valve port 4 is opened, the filling nozzle extends into the bag body 1 from the overlapping area 7 between the laminated sheets 6, when the bag body 1 is filled with materials, the lower end surface of the valve port 4 is abutted against the upper end surface of the valve port 4, and a sealing structure is formed; the second flap 62 and the first flap 61 are folded together to form a sealing structure, the overlapping area 7 prevents the material from entering the valve port 4 in the left-right direction, and the sealing structure of the valve port 4 prevents the material from entering the valve port 4 in the front-back direction. The sealing in the dual different directions can effectively prevent the material in the bag from flowing out of the bag, the utility model discloses simple structure, the sealing effect of valve port 4 is good.

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.
