[0025] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0026] Referring to Figures 1-2 , Figure 5 A folding self-standing packaging bag comprises a bag body 1 formed by heat sealing of a flexible film, the bag body 1 comprising a main face 2, a first side face 3 and a second side face 4, the first side face 3 and the second side face 4 being symmetrically arranged on both sides of the main face 2 and being heat sealedly connected with the main face 2.

[0027] A transverse pre-press folding line 5 is arranged in the middle of the main face 2, and after the main face 2 of the bag body 1 is folded along the pre-press folding line 5, the bag body 1 is converted from a flat state to a self-standing state, and the folded main face 2, the first side face 3 and the second side face 4 jointly form a supporting base for the bag body 1 to stand upright.

[0028] After the packaging bag is filled, a user manually folds the main face 2 along the pre-press folding line 5 on the main face 2 panel, and the originally flat main face 2 forms a firm V-shaped structure, which, together with the two rigid first side face 3 and second side face 4, forms a triangular cross-section three-prism supporting base, providing stable support. Even if the liquid is gradually used and the upper part of the bag body 1 is deflated, the rigid base formed by folding can still firmly stand on the plane, solving the problem of the traditional self-standing bag being tilted due to the reduction of liquid.

[0029] Referring to Figure 4 , specifically, an upper part of an intersection of the first side face 3 and the second side face 4 is provided with a discharge port 6.

[0030] Referring to Figure 3 , specifically, the discharge port 6 is provided with a cutout 7, and a peelable sealing tape 8 is arranged below the cutout 7.

[0031] The discharge port 6 is initially closed by the peelable sealing tape 8 to ensure safety in transportation and storage. When a user uses the bag for the first time, the user only needs to tear the bag body 1 along the cutout 7 and can pour out the liquid by squeezing the bag body 1. After use, the user only needs to re-press the peelable sealing tape 8 on the discharge port 6, so that reliable resealing can be realized to prevent the liquid from drying or being contaminated.

[0032] Referring to Figure 1Specifically, the main face 2 forms a V-shaped structure after being folded, and the main face 2, the first auxiliary face 3 and the second auxiliary face 4 jointly form a triangular cross-section three-prism-shaped supporting structure.

[0033] With reference to Figure 1 , Figure 4 Specifically, the main face 2 forms a flow guide channel in the inner cavity after being folded, which is folded towards the discharge port 6. When the user squeezes the bag body 1, no matter whether the first auxiliary face 3, the second auxiliary face 4 or the folded main face 2 is squeezed, the liquid flows from both sides of the bottom of the bag body 1 to the center and then flows upward to the discharge port 6, thereby reducing the liquid residue at the corners and improving the emptying efficiency.

[0034] With reference to Figure 3 Specifically, a tear opening 9 is arranged below the peelable sealing strip 8. When the liquid in the bag body 1 is almost used up, the tear opening 9 is torn to expand the opening size of the discharge port 6, so that the remaining liquid in the bag can be completely poured out, thereby further avoiding the waste caused by liquid residue. At the same time, since the opening size of the discharge port 6 is expanded, the remaining liquid can be poured out more smoothly, and the liquid is not easy to block the discharge port 6.

[0035] Specifically, the liquid level inside the bag body 1 is lower than the lower edge of the discharge port 6.

[0036] With reference to Figure 2 Specifically, the heat-sealed edges at the bottoms of the first auxiliary face 3 and the second auxiliary face 4 are horizontal straight lines.

[0037] Specifically, the inner side materials of the main face 2, the first auxiliary face 3 and the second auxiliary face 4 are aluminum foils.

[0038] Working principle: After the bag is filled, the user manually folds the main face 2 along the pre-pressing folding line 5 on the main face 2, and the originally flat main face 2 forms a firm V-shaped structure, which, together with the two straight first auxiliary face 3 and second auxiliary face 4, forms a triangular cross-section three-prism-shaped supporting base, thereby providing stable support. Even if the liquid is gradually used and the upper part of the bag body 1 is deflated, the rigid base formed by folding can still stand firmly on the plane, thereby solving the problem of the traditional self-standing bag being tilted due to the reduction of liquid.

[0039] When the user squeezes the bag body 1, no matter whether the first auxiliary face 3, the second auxiliary face 4 or the folded main face 2 is squeezed, the liquid flows from both sides of the bottom of the bag body 1 to the center and then flows upward to the discharge port 6, thereby reducing the liquid residue at the corners and improving the emptying efficiency.

[0040] The outlet 6 is initially closed by the peelable sealing band 8 to ensure safe transportation and storage, and when the user uses the bag 1 for the first time, only needs to tear the bag 1 along the incision 7, and the liquid can be poured out by squeezing the bag 1, and after use, only needs to press the peelable sealing band 8 on the outlet 6 again to realize reliable resealing, to prevent the liquid from drying or being contaminated;

[0041] When the liquid in the bag 1 is almost used up, the tear opening 9 is torn to expand the opening size of the outlet 6, so that the small amount of liquid remaining in the bag can be poured out completely, further avoiding waste caused by liquid residue, and at the same time, since the opening size of the outlet 6 is expanded, the remaining liquid can be poured out more smoothly, and the liquid is not easy to block the outlet 6.

[0042] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. In the description of the present application, it should be understood that the orientations or positional relationships indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.
