Description

Technical Field

[0001] This utility model belongs to the technical field of LCD TVs, and in particular relates to an easy-tear cardboard box for packaging LCD TVs. Background Technology

[0002] Currently, there are two main types of packaging boxes for LCD TVs: one-piece and two-piece cardboard boxes. Figure 1 As shown, this is a one-piece cardboard box, mainly used for small-sized models. Because large-sized models are larger, when using a one-piece cardboard box, it is inevitable to press on the LCD screen during unpacking and handling, which can easily damage the screen. Figure 2 The existing two-piece cardboard box consists of an upper piece 11 and a lower piece 12. The two pieces need to be connected by other connectors 13 to make them a whole. Therefore, compared with a one-piece cardboard box, the two-piece cardboard box increases the production cost (fixed connection) and material cost (connectors). Summary of the Invention

[0003] Technical Solution: To solve the above-mentioned technical problems, this utility model provides an easy-tear cardboard box for packaging LCD TVs. Specifically, the cardboard box includes a box body, a tear-off portion, and a tear line. The box body is a one-piece box structure, and at least one tear-off portion is provided on at least one cross-section. The tear line is the edge line of the tear-off portion, which can separate the tear-off portion from the box body under force.

[0004] As an improvement, the carton body is a structure composed of double-layer corrugated paper.

[0005] As an improvement, the tear line is a continuous polygonal zigzag line, one end of which starts from the apex of a cross-section of the carton body, extends along the polygon, and ends at the apex of the other end of the same side of the cross-section.

[0006] As an improvement, the polygon has one side parallel to the bottom edge of the cross-section of the carton body, and the other sides are axially symmetric along this side.

[0007] As an improvement, the number of sides of the polygon is 3 to 11.

[0008] As an improvement, the tear line includes a fold line and a tangent line, the fold line and the tangent line being arranged alternately to form the tear line, wherein the fold line is a line composed of through holes, and the tangent line is a tearable line with a direction.

[0009] Beneficial effects: The easy-tear cardboard box for LCD TV packaging proposed in this utility model can meet the requirements of improving production efficiency and reducing costs. Specifically, by adding tear lines to the integrated box, large-size LCD TVs can be easily removed when opening the box, ultimately achieving the goal of being both efficient and cost-effective.

[0017] The specific embodiments of this utility model will be described in further detail below with reference to the examples. These examples are used to illustrate this utility model, but are not intended to limit its scope.

[0018] See Figure 3 The image shows an easy-tear cardboard box for packaging an LCD TV. The box includes a box body 3, a tear-off section 2, and a tear line 1. The box body 3 is a one-piece box structure, and at least one tear-off section 2 is provided on at least one cross-section. The tear line 1 is the edge line of the tear-off section 2, which can separate the tear-off section 2 from the box body 3 under force. The box body 3 is composed of double-layer corrugated cardboard.

[0019] The tear line 1 is a continuous polygonal zigzag line, with one end starting from the apex of a cross-section of the carton body 1, extending along the polygon, and ending at the apex of the other end of the same side of the cross-section. The polygon has one side parallel to the bottom edge of the cross-section of the carton body 3, and the other sides are axially symmetric along this side. Preferably, the number of sides of the polygon is 3 to 11.

[0020] Example 1

[0021] See Figure 4As shown, the tear line 1 includes a fold line 1-1 and a tangent line 1-2. The fold line 1-1 and the tangent line 1-2 are spaced apart to form the tear line. The fold line 1-1 is a line formed by through holes, and the tangent line 1-2 is a directional tearable line. The tangent line 1-2 allows the part to be torn 2 to be separated from the carton body 3, and the fold line 1-1 allows it to extend in a predetermined shape, preventing the tear line position from shifting. To prevent unnecessary tearing, the starting end is a fold line.

[0022] The working principle of this invention involves adding a tear-line structure to the front or back of the cardboard box. When opening the box, the top sealing tape 4 is removed, and the box can be easily torn open from point A at the top. After tearing open the box, the bottom of the TV can be easily lifted, avoiding pressure on the LCD screen. This allows the TV to be safely removed from the packaging. This invention, by adding a tear-line to a one-piece cardboard box, makes it suitable for large-size LCD TVs. It facilitates unpacking and handling operations and also saves on connector and production costs.

[0023] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
