DETAILED DESCRIPTION

[0024] like Figure 1-5As shown, the side sealing structure, semi-finished product and finished product of the packaging material of this embodiment can be a packaging box for milk, juice or other types of objects. The packaging box can be formed by combining the side A2 and the side B3. Since the packaging material is generally a paper-based composite material, it will produce a molding line when folded. The line in the figure is a simulated schematic line. When it is different from the molding line, it does not affect its protection range.

[0025] like Figure 2-3 , which forms an outer folded ear portion 11, which cannot be sealed at the transition edge 13, forming an inner groove portion 14. The problems it has include retention of beverage liquid and disinfectant, the inability to weld and seal the transition, and the folded ears are arranged outward, so the folded ears need to be welded twice. When displayed or transported in a supermarket, the outer folded ear portion 11 is easily opened due to squeezing or human intervention, thereby affecting the appearance of the packaging box / bag or box.

[0026] In order to solve the above technical problems, Figure 1 4 and 5, the side sealing structure of the packaging material in this embodiment includes a sealing side surface B5; an inner folding ear portion 15 is provided between the sealing side surface B5 and the end surface portion 1; the folding ear is formed according to Figure 1 Just fold in the direction.

[0027] The sealing side surface B5 includes a sealing cover portion 6 as a sealing portion;

[0028] The inner folded ear portion 15 is arranged in close contact with the inner side wall of the cover portion 6;

[0029] The inner folding ear portion 15 is protruding toward the inner cavity of the packaging material. Compared with the outer folding ear portion, it does not have an inner groove and can achieve better overall sealing welding without the problem of being unable to weld at the transition point. As a result, the folding ear is not exposed, thereby preventing it from being opened.

[0030] The inner folded ear portion 15 is sealed and / or the inner folded ear portion 15 and the cover portion 6 are sealed, so that the protection range is larger and the sealing effect of the inner folded ear portion 15 and the cover portion 6 is better.

[0031] The inner folded ear portion 15 includes a middle triangular area 9 connected to the end surface portion 1 through a transition edge portion 13. For the convenience of description, the triangular area may also be a trapezoid or other similar structures;

[0032] There are two side triangular areas A10 connected to the two oblique sides of the middle triangular area 9. Similarly, the triangular area can also have other similar structures, all of which are protection ranges;

[0033] The two flipped side triangular areas A10 are located between the middle triangular area 9 and the corresponding facing cover 6, and are folded together and welded into one;

[0034] The middle triangular area 9 is turned over and attached to the side triangular area A10 to form a side folded edge 16, which is welded to the cover portion 6 as a whole.

[0035] As a main structural explanation, the side triangle area A10 is connected to the side flange portion A8; the side flange portions A8 on both sides are attached to form a flange portion 12;

[0036] The cover portion 6 is connected to a side sealing portion 7;

[0037] The side sealing edges 7 on both sides are arranged in close contact with each other, thereby achieving side sealing.

[0038] The flanged portion 12 is located between the side sealing portions 7 on both sides, thereby achieving sealing welding.

[0039] As an extended protection, the packaging material side sealing semi-finished product of this embodiment includes a packaging material side sealing structure, wherein the first side surfaces A4 are connected to both sides of the end surface 1; and the first side surfaces A4 are connected to the cover surface 6 on both sides;

[0040] The front cover 6 is connected to the side sealing portion 7 to form the side surface of the packaging material.

[0041] As an extended protection, the finished product of the packaging material side sealing in this embodiment includes a semi-finished product of the packaging material side sealing.

[0042] Before filling, the folded ears are welded to prevent liquid from entering the folded ear area, and before disinfection, they are sealed to prevent disinfectant from entering, thereby avoiding the accumulation of disinfectant.

[0043] The end surface 1 can be installed with a bottle cap or a film or directly sealed. Figure 1 direction, converted into Figure 4 After the state, Figure 4 The directions are folded to form a semi-finished product.

[0044] The packaging material has a laminated film or a bottle cap.

[0045] The present invention is fully described for a clearer disclosure, and the prior art will not be listed one by one.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it; although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein with equivalents; it is obvious for those skilled in the art to combine multiple technical solutions of the utility model.
