Description

Technical Field

[0001] This utility model relates to the field of packaging paper bag technology, and in particular to a stable vertical packaging paper bag. Background Technology

[0002] Most existing packaging paper bags have a folded structure, which is used by unfolding. When placed, the bottom is flat and the sides are vertical. When placed in a three-dimensional manner, the load-bearing stability of the outer edge is relatively poor. For paper bags that require three-dimensional placement, thicker paper is usually used to ensure stability when placed, but the material cost is relatively high. Utility Model Content

[0003] The purpose of this invention is to provide a stable vertical packaging paper bag. By setting a stable support auxiliary surface on the side of the paper bag, and combining it with the outward protrusion of the main body, a stable three-dimensional placement effect can be formed. The paper bag does not need to use thick paper to achieve stable vertical placement, and the overall material cost is lower and the placement stability is better.

[0004] The technical solution of this utility model is as follows: A stable, upright packaging paper bag, characterized in that: it includes a main structure of the packaging paper bag, the front and rear sides of which are outwardly protruding arc-shaped structures, the left and right sides of which are outwardly opening arc-shaped outer three-dimensional surfaces, a conical stabilizing support auxiliary surface is provided at the lower end of the front and rear sides of the outer three-dimensional surface, the lower end of the stabilizing support auxiliary surface is an arc-shaped structure, the upper end of the stabilizing support auxiliary surface coincides with the outer edge of the outer three-dimensional surface in the width direction, the interior of the main structure of the packaging paper bag has an upwardly opening internal storage space, the inner and outer sides of the internal storage space are parallel to each other, and the lower end of the internal storage space has a uniformly distributed wave-shaped placement stabilizing and reinforcing structure.

[0005] Furthermore, the width of the upper and lower sides of the main structure of the packaging paper bag is the same.

[0006] Furthermore, the height of the stabilizing support auxiliary surface in the vertical direction is the same as the height of the outer three-dimensional surface in the vertical direction.

[0007] Furthermore, the placement and reinforcement structure is manufactured by molding.

[0008] The beneficial effects of this utility model are: This invention creates a stable three-dimensional placement effect by setting a stable support auxiliary surface on the side of the paper bag and combining it with the outward protrusion structure of the main body. The paper bag does not need to use thick paper to achieve stable vertical placement, resulting in lower overall material costs and better placement stability. Attached Figure Description

[0009] Figure 1 This is a three-dimensional structural diagram of the present invention; Figure 2 This is a front view of the present invention; Figure 3 This is a schematic diagram of the left side of this utility model; In the diagram: 1. Main structure of the packaging paper bag; 2. Outer three-dimensional surface; 3. Stable supporting auxiliary surface; 4. Internal storage space of the packaging bag. Detailed Implementation

[0010] like Figures 1 to 3 As shown, a stable upright packaging paper bag includes a main packaging paper bag structure 1. The front and rear sides of the main packaging paper bag structure 1 are outwardly protruding arc-shaped structures, which increases the internal space. The left and right sides of the main packaging paper bag structure 1 are outwardly opening arc-shaped outer three-dimensional surfaces 2. A conical stabilizing support auxiliary surface 3 is provided at the lower end of the front and rear sides of the outer three-dimensional surface 2, which improves the stability of the lower side support and makes the side strength more stable. The lower end of the stabilizing support auxiliary surface 3 is an arc-shaped structure, and the upper end of the stabilizing support auxiliary surface 3 coincides with the outer edge of the outer three-dimensional surface 2 in the width direction, which improves the overall load-bearing capacity of the outer structure. The interior of the main packaging paper bag structure 1 has an upward-opening internal storage space 4. The inner and outer sides of the internal storage space 4 are parallel to each other. The lower end of the internal storage space 4 has a uniformly distributed wave-shaped placement stabilizing and reinforcing structure, which increases the structural strength of the bottom, prevents side slippage during placement, makes the placement more reliable, and ensures a stronger load-bearing capacity. By setting a stable support auxiliary surface on the side of the paper bag, and combining it with the outward protrusion of the main body, it can form a stable three-dimensional placement effect. The paper bag does not need to use thick paper to achieve stable vertical placement, resulting in lower overall material costs and better placement stability.

[0011] Preferably, the width of the upper and lower sides of the main structure 1 of the packaging paper bag is the same, which makes the overall structural support strength better, the service life during use longer, and the overall internal space larger.

[0012] Preferably, the height of the stable support auxiliary surface 3 in the vertical direction is the same as the height of the outer three-dimensional surface 2 in the vertical direction, resulting in higher overall load-bearing strength on the outer side and stronger support when placed vertically.

[0013] Preferably, the placement and reinforcement structure is manufactured by mold pressing, which can ensure higher processing accuracy and higher production efficiency, while ensuring more reliable structural stability on the outer side. If splicing and bonding are used, the overall processing efficiency will be lower and the production cost will be higher.

[0014] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements or substitutions can be made without departing from the principle of this utility model, and these improvements or substitutions should also be considered within the protection scope of this utility model.
