Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging box technology, and in particular to a new type of packaging box blank based on traditional culture. Background Technology
[0002] It is widely used in the packaging of liquid foods such as dairy products and juices. However, traditional packaging box designs still have significant shortcomings in terms of user experience and brand differentiation. In existing technologies, the box structure mostly adopts a symmetrical folded line design.
[0003] This design has several drawbacks: 1. The box is prone to slipping when the lid is on or when the user's hands are wet; 2. When emptying the bottle, contents may remain at the bottom of the box, leading to waste; 3. The homogeneous structure makes it difficult for consumers to quickly identify specific products on the shelf. Utility Model Content
[0004] The main purpose of this utility model is to provide a new type of packaging box blank based on traditional culture, which aims to solve the technical problems of existing boxes being easy to slip, easy to leave residue on the bottom of the box, and difficult to identify.
[0005] To achieve the above objectives, this utility model provides a novel packaging box blank based on traditional culture, including a main body cut from a paper-plastic composite sheet. The main body has indentations, and the main body can be folded and glued through the indentations to form a packaging box. The packaging box has an inverted trapezoidal design for anti-slip and convenient emptying of all liquids inside the box.
[0006] Furthermore, the indentation divides the main body into several regions, namely, the bottom surface region, the side surface region, the top surface region, the top surface bonding region, the side surface bonding region, and the bottom surface bonding region.
[0007] The side areas of the box are mutually fitted inverted isosceles trapezoids;
[0008] An exit is provided on the top area of the box.
[0009] Furthermore, the bottom angle of the inverted isosceles trapezoid is α, where α is 91°-100°.
[0010] Furthermore, the packaging box is formed by bonding the inner wall of the side bonding area to the outer wall of the bottom area, the side area, and the top area; pressing the bottom, bonding the inner wall of the bottom bonding area to the outer wall of the bottom area; pressing the top, bonding the top bonding area and the joint.
[0011] Furthermore, the top area of the box is pressed with diagonal creases that overlap at the top and are symmetrical about the axis; the bottom area of the box is pressed with diagonal creases that overlap at the bottom and are symmetrical about the axis.
[0012] Furthermore, indentations are pressed into the bonding area on the top of the box and at the axis of symmetry.
[0013] Furthermore, the paper-plastic composite sheet includes an inner layer, a middle layer, and an outer layer;
[0014] The outer layer is either a high-barrier layer or a PE layer;
[0015] The intermediate layer is any one or more of the following: high barrier layer, PE layer, adhesive layer, aluminum foil layer, composite layer, and paper layer;
[0016] The inner layer is either a high-barrier layer or a PE layer.
[0017] The beneficial effects of this utility model are reflected in:
[0018] The special shape gives the packaging a natural curve, making it easier to grip and the contents easier to pour out;
[0019] Its unique appearance and structure differentiate it from traditional packaging on the shelf, making it easier to stand out and helping consumers quickly identify it among many similar products. Attached Figure Description
