Detailed ways

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Referring to FIG. 1, the blank for manufacturing a liquid packaging container according to the first embodiment includes: a packaging material, which is divided into five lateral regions by four horizontal folds 100, that is, a first folding region 1000 and a first sidewall. The area 2000, the second folding area 3000, the second side wall area 4000, and the third folding area 5000 are sequentially disposed from top to bottom; the first folding area 1000 is provided with a first lower end surface area 1100, a first folded area 1200, and a The first folded area 1200 and the second folded area 1300 are symmetrically disposed on the left and right sides of the first lower end surface area 1100; the second folded area 3000 is provided with an upper end surface area 3100 and a third folded area. 3200 and the fourth folding area 3300, the third folding area 3200 and the fourth folding area 3300 are symmetrically disposed on the left and right sides of the upper end surface area 3100; the third folding area 5000 is provided with the second lower end surface area 5100, the fifth The folding area 5200 and the sixth folding area 5300, the fifth folding area 5200 and the sixth folding area 5300 are symmetrically disposed on the left and right sides of the second lower end surface area 5100; the left and right sides of the packaging material are provided for forming a seal Seam Sealing crease 200; upper end surface region 3100 is used to form upper end surface 1, and first lower end surface 1100 and second lower end surface 3100 are spliced together to form lower end surface 2, and first sidewall region 2000 and second sidewall region 4000 are spliced together Side walls to form a closed packaging container. Sealing creases 200 for forming a sealing seam may also be provided on the upper and lower sides of the blank.

Since the sealing creases 200 are not provided on the upper and lower sides of the blank, it is necessary to bond the inner surface of one side of the blank to the outer surface of the other side for sealing. Of course, it is also possible to provide the seal crease 200 on the upper and lower sides, and to seal the inner surface of the upper and lower sides of the blank for sealing.

Since the upper end surface is directly formed by the upper end surface region 3100 without being spliced and stitched, the circular mark or the cap mark for inserting the suction pipe can be disposed at the center of the upper end surface 1 while not exceeding the size of the upper end surface 1 Within the scope of the application, you can install a larger cap according to the actual needs. For example, when you need to hold a thicker beverage such as old yogurt, you need to use it with a spoon. At this time, install a large-sized bottle cap so that the spoon can stretch. Enter the opening of the cap to eat the food. The blank in the circular marking or cap marking area is generally thinner than the blanks in other areas to facilitate penetration by the straw and to facilitate the setting of the cap. Of course, in addition to being disposed at the center of the upper end surface 1, the circular mark or the cap marking area can be set at other positions.

Referring to FIGS. 3 and 4, in general, the upper end surface 1 and the lower end surface 2 of the packaging container are rectangular, so the upper end surface area 3100, the first lower end surface area 1100, and the second lower end surface area 5100 are both rectangular, on the upper end surface. A vertical fold 300 is disposed on both sides of the region 3100, the first lower end surface region 1100, and the second lower end surface region 5100, and the first lower end surface region and the second lower end surface region are formed after the splicing is completed for convenience of manufacture and appearance. The lower end surface 2 and the upper end surface 1 area are identical in size and shape. It is also possible to design the shape of the upper and lower sides or the upper and lower sides according to actual needs, and it is only necessary to adjust the rectangular size corresponding to the upper end surface region 3100, the first lower end surface region 1100, and the second lower end surface region 5100. Of course, the rectangle described here contains a special case of squares.

The first side wall region 2000 and the second side wall region 4000 are both provided with auxiliary creases 400 for auxiliary molding, and the intersection of the vertical crease 300 and the horizontal crease 100 is the first point 3, from each of the first points 3 extends two auxiliary creases 400. Referring to FIG. 2, the packaging container is diamond-shaped, and is more easily formed, thereby improving production efficiency. At the same time, the two auxiliary creases 400 extending from the same first point 4 can be symmetrically arranged, so that a more aesthetic appearance can be obtained.

The first lower end surface region 1100 is further provided with a fold crease 500 extending from the first point 4, and at the time of molding, due to the existence of the fold crease 500, after folding according to the fold crease 500, corresponding thereto The horizontal fold 100 and the vertical fold 300 coincide to achieve partial molding, and similarly, in the second folded region 1300, the third folded region 3200, the fourth folded region 3300, the fifth folded region 5200, and A corresponding fold position in the sixth folded region 5300 is also provided with a fold crease 500.

The blank of this embodiment is usually a multi-layer material, and all the creases are formed by pressing or characterization. The blank comprises seven layers of material, and the seven layers of material are from the outside (the outside of the packaging container after forming the packaging container) to the inside (the inside of the packaging container after forming the packaging container): PE layer, adhesive layer, paper layer, PE layer, adhesive layer, aluminum foil layer, adhesive layer, PE layer, and PE modified layer (Note: the circular marking area for the insertion straw or the material layer included in the blank for the area where the cap is set) The number is usually less than seven layers). This embodiment does not limit the number of layers of the material included in the blank and the specific materials used for the material of each layer.

Referring to Fig. 2, the packaging container of the second embodiment is formed by the blank shown in Fig. 1. The process of forming the packaging container may be: when the sealing creases 200 are not provided on the upper and lower sides of the blank, the inner surface of the blank from one side Bonding to the outer or inner surface of the other side of the blank to form a sealing seam to achieve sealing; if the upper and lower sides of the blank are provided with a sealing crease 200, the inner surface of one side of the blank and the inner surface of the other side of the blank Bonding forms a sealing seam to achieve sealing. After the lower end surface 2 is sealed, the sealing creases 200 on both sides of the blank are sealed to form a sealing seam, and the canned liquid can be used before the sealing seam is sealed on either side. The tank can also be reserved in any one of the sealing joints, and the cans are sealed after the canning is completed. The choice of the timing of the canned liquid does not limit the protection range of the present invention. Then, the current shape of the package is caged, respectively, for the first folded region 1200 and the second folded region 1300 of the first folded region 1000, and the fifth folded region 5200 and the sixth folded region of the third folded region 5000, respectively. The folded area 5300 is folded such that the first lower end surface area 1100 and the second lower end surface area 5100 are spliced together to form the lower end surface 2, and then the third folded area 3200 and the fourth folded area 3300 of the second folded area 3000 are further Folding, so that the upper end surface region 3100 forms the upper end surface 2, for the sake of beauty, the first folding region 1200, the second folding region 1300, the fifth folding region 5200, and the sixth folding region 5300 are arranged in the region thereof. The fold crease 500 is folded and folded over the lower end face 2, and the third folded region 3200 and the fourth folded region 3300 are folded toward the first side wall according to the fold crease 500 disposed in the region thereof. The side walls formed by the area 2000 and the second side wall area 4000 are folded over. If the auxiliary crease 400 is not provided, the side wall naturally forms a circular drum shape. When the auxiliary crease 400 is provided, the side wall is formed like a diamond-shaped side wall due to the auxiliary crease 400, so that the appearance is more beautiful and elegant. It is also convenient for uniform packaging after mass production of packaging containers.

As described above, the embodiments of the present invention have been described in detail, but it will be obvious to those skilled in the art that the invention may be variously modified without departing from the spirit and scope of the invention. Therefore, such modifications are also fully included in the scope of the present invention.
