To achieve the above object, the present invention adopts the technical scheme that：
A kind of valve bag with automatic open function, including paper bag body, upper bottom portion, lower bottom part；With the paper bag sheet
Body is matrix, and the upper bottom portion is separately positioned on the upper end and lower end of paper bag body with the lower bottom part；It is characterized in that：Upper bottom
Portion is provided with valve mouth structure；One end of the valve mouth structure is arranged on the side edge of paper bag body, and the other end is arranged on paper bag sheet
The inside of body；
Further improve, the valve mouth structure is the valve mouth structure of automatic open；
Further improve, the valve mouth structure includes paper, and is crowded around and formed by the paper；
Further improve, the valve mouth structure is shaped as flat compression shape；
Further improve, the upper bottom portion of the paper bag body is provided with knuckle area, and the knuckle area is provided with glue, is first
Glue；The valve mouth structure is bonded in the knuckle area by the glue；
Further improve, the paper bag body includes paper and PE films；The paper is arranged on the outside of PE films, the paper
Open and glue is provided between the PE films, be the second glue；The paper is bonded together by the glue and the PE films；
Further improve, the paper is one or more layers paper；
Further improve, the PE films are high intensity Obstruct membrane.
Compared with prior art, using such scheme, the beneficial effects of the invention are as follows：The present invention utilizes being capable of automatic open
Valve mouth structure realize the automatic open of paper bag, so canned when, because paper bag being capable of automatic open, it is not necessary to artificial
Valve bag is opened, in the process of packaging production, the time is saved, also just improves the canned efficiency in packaging process, it is whole
Individual product structure is simple, practical, substantially increases the efficiency of canned production.

Embodiment
The present invention is further described with example below in conjunction with the accompanying drawings.
As shown in Figure 1,2,3, 4, a kind of valve bag with automatic open function, including paper bag body 1, upper bottom portion 2, under
Bottom 3；It is matrix with the paper bag body 1, the upper bottom portion 2 is separately positioned on the upper end of paper bag body 1 with the lower bottom part 3
And lower end；It is characterized in that：Upper bottom portion 2 is provided with valve mouth structure 4；One end of the valve mouth structure 4 is arranged on paper bag body 1
Side edge, the other end are arranged on the inside of paper bag body 1；
The valve mouth structure 4 is the valve mouth structure 4 of automatic open；The valve mouth structure 4 includes paper, and passes through the paper
Crowd around and form；The valve mouth structure 4 is shaped as flat compression shape；
The upper bottom portion 2 of the paper bag body 1 is provided with knuckle area 16, and the knuckle area 16 is provided with glue, is the first glue
17；The valve mouth structure 4 is bonded in the knuckle area 16 by the glue；
The paper bag body 1 includes paper and PE films 5；The paper is arranged on the outside of PE films 5, the paper with it is described
Glue is provided between PE films 5, is the second glue 10；The paper is bonded together by the glue and the PE films 5；The paper
It is one or more layers paper to open；The PE films 5 are high intensity Obstruct membrane；
Specific embodiment one：As shown in Figure 1 and Figure 2, a kind of valve bag with automatic open function, including paper bag body
