Description

Technical Field

[0001] The utility model relates to the technical field of packaging cartons, in particular to an environmentally friendly, pressure-resistant and shock-proof packaging cartons. Background Art

[0002] Cardboard boxes are widely used in the packaging industry due to their light weight and low cost. However, compared to wooden boxes, cardboard boxes have lower compressive strength. To improve their compressive and shock-absorbing properties, the common practice is to increase the thickness of the cardboard boards, but this also significantly increases production costs and weight.

[0003] Furthermore, packaging cartons are often sealed with tape or cable ties, which are single-use and cannot be resealed after opening. New tape or cable ties are required, resulting in significant cost and environmental impact. Furthermore, cable ties require specialized tools to secure the joints, and removal typically involves cutting with scissors, which is also impossible with bare hands and warrants improvement.

[0017] Figure 3 yes Figure 2 BB cross-sectional view. DETAILED DESCRIPTION

[0018] The following combination Figures 1 to 3 The technical solution of the present utility model is further illustrated by specific embodiments.

[0019] like Figure 1 and Figure 2 The environmentally friendly, pressure-resistant and shock-proof packaging carton shown includes: a carton base 1, a pad 5, a pull piece 6, a support 4, a base 3 and a cover 2. The carton base 1 is arranged on the base 1, and the cover 2 is arranged on the top of the carton base 1. In this embodiment, the carton base 1 adopts a square closed carton structure surrounded by carton boards, and the base 1 adopts a paper shell with an open top surrounded by carton boards. The bottom of the carton base 1 is placed on the base 1 to reinforce the bottom of the carton base 1.

[0020] The cover 2 is made of a carton board to form a paper shell with an open bottom, which can cooperate with the carton base 1 to seal the top of the carton base 1. The cover 2 is easy to open and close, and no tape or tie is required.

[0021] The pad 5 is set at the bottom of the inner cavity of the carton base 1. In this embodiment, the pad 5 is made of at least one layer of corrugated cardboard, which has a good shock absorption effect. The pad 5 is used to separately thicken the bottom of the inner cavity of the carton base 1 to improve the shock absorption effect of the packaged goods.

[0022] like Figure 2 and Figure 3 As shown, the support members 4 are vertically arranged on each corner of the inner cavity of the carton base 1. In this embodiment, the support members 4 adopt a carton board bending structure with an L-shaped cross-section, and the height of the support members 4 corresponds to the height of the inner cavity of the carton base 1. The support members 4 can be used to support the four corners of the carton base 1, thereby improving the pressure resistance effect while controlling the cost and weight.

[0023] like Figure 3 As shown, the corners of the pad 5 are provided with card slots 51 corresponding to the support members 4, and the card slots 51 are used to position the support members 4 at the corners of the inner cavity of the carton base 1, thereby improving assembly convenience and structural stability.

[0024] like Figure 1 As shown, first waist holes 21 extending laterally are respectively provided around the cover body 2, and second waist holes 31 corresponding to the first waist holes 21 are respectively provided around the base 3, so as to facilitate the insertion of fingers, and simplify the disassembly, assembly and transportation operations.

[0025] The pull member 6 is arranged around the carton base 1 and between the base 3 and the cover 2. The pull member 6 includes a first positioning block 61, a second positioning block 62 and a pull rod 63. The first positioning block 61 is arranged in the first waist hole 21, and the second positioning block 62 is arranged in the second waist hole 31. The pull rod 63 is vertically arranged between the first positioning block 61 and the second positioning block 62. In this embodiment, the first positioning block 61, the second positioning block 62 and the pull rod 63 are an integrated plastic structure, which realizes the pulling and securing of the base 3 and the cover 2, and improves the stability of the cover 2 after sealing the top of the carton base 1.

[0026] like Figure 2 As shown, the thickness of the first positioning block 61 and the second positioning block 62 are respectively greater than the thickness of the pull rod 63. The pull rod 63 is thin and can pass through the gap between the base 3 and the inner wall of the cover 2 and the outer wall of the carton base 1 without affecting the structure of the base 3 and the cover 2.

[0027] In addition, in this embodiment, the top of the outer side of the first positioning block 61 is provided with a chamfer 64, which makes it easier for the first positioning block 61 to enter the gap between the inner wall of the cover body 2 and the outer wall of the carton base 1 during assembly, thereby entering the first waist hole 21 to complete the assembly. When disassembling the cover body 2, the first positioning block 61 is pressed inward to disengage the first positioning block 61 from the first waist hole 21, and the pull rod 63 can be pulled down to release the lock on the cover body 2. The pull piece 6 can be reused, which reduces costs and does not require tape or cable ties, making it more environmentally friendly.

[0028] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
