Furthermore, the terms "first," "second," and the like are used merely to distinguish one description from another, and are not to be construed as indicating or implying relative importance.

Referring to fig. 1 and 2, an embodiment of the present invention provides a packaging bag 10, where the packaging bag 10 is used for containing articles, such as washing powder and salt, which need to be taken for multiple times, in this embodiment, the packaging bag 10 is used for containing washing powder.

The package 10 is made of a plastic composite film, and the material of the package 10 can be referred to the prior art.

The packaging bag 10 includes a bag body 110, and the overall shape of the bag body 110 is not limited, such as a rectangle, an irregular shape, and the like, and in the present embodiment, the shape of the bag body 110 is a rectangle.

The bag body 110 has two opposite bag sheets 111, and the two bag sheets 111 are a front bag sheet 111 and a rear bag sheet 111, respectively.

The peripheries of the two bag pieces 111 are sealed, a beading machine can be selected for pressing in a sealing mode, the pressing mode can be combined after being melted by heating, a containing cavity is formed between the two bag pieces 111, and washing powder can be contained in the containing cavity.

In the prior art, the bag body 110 is generally made by the following two methods:

first, as shown in fig. 1, the bag body 110 is an integral film, and is folded in half, the folded part is located in the vertical middle of the rear bag sheet 111, and then the folded part and the upper and lower ends are respectively pressed. Of course, in actual production, the folded portion and the bottom of the bag body 110 may be pressed together first, and then the top of the bag body may be pressed together after the washing powder is injected into the accommodating cavity.

Secondly, as shown in fig. 2 and 3, the bag body 110 is formed by bonding two independent bag sheets 111, and then the peripheries of the bag body 110 are respectively pressed. Of course, in actual production, the bottom and the two side portions of the bag body 110 may be pressed first, and then the top portion may be pressed after the washing powder is injected into the accommodating cavity.

In the second scheme, the two bag sheets 111 are independent from each other, and the bag body 110 is provided with press-fit edges 115 at the periphery.

The production mode of the first bag body 110 is simple, but because the side part is formed by bending the film, the two bag pieces 111 on the side part are difficult to completely attach, and the two bag pieces 111 can be easily attached by the arrangement mode of the second bag body 110, in the embodiment, the second mode can be selected for the bag body 110.

One of the corners of the bag body 110 is a pouring corner 112, the pouring corner 112 means that a user can open the bag body at this position, and the opening mode can be cutting with scissors or directly tearing, as shown in fig. 3.

The pouring corner 112 is provided with a stitching portion 113, the number of stitching portions 113 is not limited, and may be two, three, etc., for example, and the stitching portions 113 have a strip shape.

The two sheets 111 of the bag body 110 are pressed at the pressing part 113, the processing mode of the pressing part 113 can be the same as the edge pressing mode of the packaging bag 10, and the pressing can be performed by using the existing edge pressing machine.

The direction of the stitching portion 113 is not limited, and in the present embodiment, the following two schemes can be adopted, but not limited:

in the first scheme, the plurality of stitching portions 113 are arranged side by side, the stitching portions 113 extend in the vertical direction, and the direction of the stitching portions 113 may be substantially parallel to the side edges.

With such an arrangement, the maximum pouring speed can be controlled by exposing the pouring passages 114 at different positions according to the size of the shearing opening.

In the second scheme, the pressing portion 113 and the top of the bag body 110 form an included angle, and the inclination angles of the different pressing portions 113 with respect to the top of the bag body 110 are gradually increased in the direction from near to far from the top of the bag body 110.

The pressing portions 113 are radially distributed, and can flow out from the pouring channels 114 with different numbers according to the inclination angle of the packaging bag 10, so that the pouring amount and the pouring speed can be more accurately controlled.

Both sides of the nip 113 are pouring channels 114, the maximum flow at each pouring channel 114 being smaller.

In addition, at the same opening, the opening area without the pressing portion 113 is larger than the opening area with the opening and closing portion.

For example, without considering the width of the nip 113, there is no opening of the nip 113: the length of the opening is 3cm, namely, the two bag sheets 111 are both 6cm at the opening, the opening is circular when the area is the largest, 2 pi R =6, R is the radius, and the largest area is pi R ² And (3) = 9/pi. There are two openings for the press-fit portion 113: divide the opening into three pouring channels 114, then 2 π r 3=6, r is the radius, the largest areaIs pi r ² *3＝3/π。

Further, the opening is cut at different positions, and the increase of the opening area without the nip portion 113 is larger than the increase of the opening area with the nip portion 113, so that even if the position of the opening is deviated, the influence on the size of the opening of the nip portion 113 is small.

Referring to fig. 4, the package 10 further includes a sealing strip 121, the sealing strip 121 is obliquely disposed at the pouring corner 112, and the sealing strip 121 can be fastened or separated to seal and open the pouring corner 112.

The structure of sealing strip 121 can refer to prior art, and sealing strip 121 includes first rubber strip and second rubber strip promptly, and first rubber strip and second rubber strip set up respectively in the opposite side of two bag pieces 111, are provided with banding catching groove on the first rubber strip, are provided with banding profile buckle strip on the second rubber strip, and the profile buckle strip can insert the catching groove and make sealing strip 121 sealed, and simultaneously, the profile buckle strip can be opened when breaking away from in the catching groove.

In addition, because the washing powder needs to be taken out for multiple times, only a small part of the washing powder is used each time (except the case of taking out the washing powder once and pouring the washing powder into other storage devices), if the traditional press-fit type sealing strip 121 is adopted, the washing powder needs to be opened and closed each time, and the washing powder is complex and inconvenient to use.

Therefore, in the present embodiment, the following is provided: the package 10 further includes two electrostatic absorption strips 120, and the electrostatic absorption strips 120 are disposed obliquely and adjacent to the pouring angle 112.

The electrostatic adsorption strip 120 is made of a plastic sheet with static electricity, i.e., an electrostatic film, which is already common in the prior art, and the electrostatic adsorption strip 120 has certain flexibility and can deform along with the deformation of the bag sheet 111.

In this embodiment, the electrostatic absorption strip 120 is a rectangular strip structure, the two electrostatic absorption strips 120 are respectively disposed on opposite sides of the two bag sheets 111, the periphery of the electrostatic absorption strip 120 is pressed with the bag sheets 111 or the electrostatic absorption strip 120 is integrally pressed with the bag sheets 111, and the pressing manner may be the same as the pressing manner of the pressing portion 113 and the pressing manner of the pressing edge 115.
