Description

paper plastic box

technical field

The utility model relates to the field of product packaging, in particular to a paper-plastic packaging box for packaging various electronic products (especially notebook computers).

Background technique

Laptops, mobile phones, cameras and other electronic products are relatively expensive, and their own shock resistance and pressure resistance are poor, so they need to be protected during transportation and storage to prevent possible vibration, extrusion, Damaged by falling or impacting, causing unnecessary losses.

At present, in order to ensure that consumers can receive undamaged products, foam linings are provided in the packaging boxes of various electronic products (especially notebook computers and computer hosts). The outer contours are matched to play a role of cushioning and shock absorption; in addition, some manufacturers place fillers made of foam particles, shredded paper strips or plastic inflatable bags in the space between the packaging box and the product. Although foam and plastic are easy to process and low in price, they are the main environmental pollutants, cannot be recycled and reused, and are basically non-degradable in the natural environment, and will release toxic gases when burned, so a large amount of foam or plastic does not meet environmental protection requirements . At the same time, the use of foam lining or filling will increase the volume of the product packaging box, thereby increasing product costs and wasting resources.

Utility model content

In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the utility model is to provide a paper-plastic packaging box with good cushioning performance and environmental protection.

In order to achieve the above purpose, the utility model provides a paper-plastic packaging box, which includes a bottom bracket and an upper cover. The bottom bracket is provided with a storage slot. Among the four side walls of the bottom bracket, at least three of the upper edges of the side walls There are foldable flaps extending outward, and the flaps are provided with a plurality of stepped grooves distributed along the length direction of the flaps. At the bottom of the flaps, the groove bottoms of the stepped grooves form A plurality of stepped protrusions, the stepped protrusions include a lower first step and a higher second step, when the flap is folded down, the first step and the side wall where the flap is located Fittingly, the second step is clamped on the lower edge of the side wall where the flap is located.

Preferably, the upper cover is provided with a concave-convex structure for buffering.

Preferably, the upper cover is provided with a plurality of bumps which function as buffers.

Further, the storage slot includes a main slot and an accessory slot located on one side of the main slot, and there are three flaps, which are respectively located on the remaining three sides of the main slot.

As mentioned above, the paper-plastic packaging box related to the utility model has the following beneficial effects:

The paper-plastic packaging box protects the products in the storage slot through the multiple step-shaped grooves on the flap, and the cooperation between the first step, the second step and the side wall of the bottom support, thereby playing a good cushioning and shock absorption At the same time, the paper-plastic packaging box is made of environmentally friendly materials that do not consume resources such as recycled pulp, straw pulp, bamboo pulp, or sugarcane pulp. a circular economy.

Detailed ways

The implementation of the present utility model is illustrated by specific specific examples below, and those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification.

It should be noted that the structures, proportions, sizes, etc. shown in the drawings attached to this specification are only used to match the content disclosed in the specification, for those who are familiar with this technology to understand and read, and are not used to limit the implementation of the utility model Therefore, it has no technical substantive meaning. Any modification of structure, change of proportional relationship or adjustment of size shall still fall within the scope of The technical content disclosed by the utility model must be within the scope covered. At the same time, terms such as "upper", "lower", "left", "right", and "middle" quoted in this specification are only for convenience of description, and are not used to limit the implementation of the present utility model. The change or adjustment of its relative relationship, without substantive changes in the technical content, should also be regarded as the scope of the utility model that can be implemented.

The utility model provides a paper-plastic packaging box, which is made of environmentally friendly materials that do not consume resources such as recycled pulp, straw pulp, bamboo pulp or sugarcane pulp, and is used for packaging electronic products, especially notebook computers. As shown in Figures 1 to 6, the paper-plastic packaging box includes a bottom support 1 and an upper cover 2, the bottom support 1 is provided with a storage slot 11, and among the four side walls of the bottom support 1, at least three side walls There are foldable flaps 3 extending outwards from the upper edge of the flap 3, and a plurality of stepped grooves 31 distributed along the length direction of the flaps 3 are arranged on the flaps 3. At the bottom of the flaps 3, the The groove bottom of the stepped groove 31 forms a plurality of stepped protrusions 4, and the stepped protrusions 4 include a lower first step 41 and a higher second step 42. When the flap 3 is folded down, , the first step 41 is attached to the side wall where the flap 3 is located, and the second step 42 is stuck on the lower edge of the side wall where the flap 3 is located.

In the paper-plastic packaging box, the stepped groove 31 on the flap 3 and the first step 41 and the second step 42 forming the stepped protrusion 4 are the buffer structure of the bottom support 1, and they jointly face the storage slot 11 The product inside acts as a buffer and shock absorber, thereby effectively preventing the product from being damaged due to possible impact or drop during its transportation and storage, so as to ensure that consumers receive intact products. In addition, the second step 42 supports the products in the storage tank 11 together with the bottom of the storage tank 11 while playing a buffering role. At the same time, the paper-plastic packaging box is made of environmentally friendly materials, meets environmental protection requirements, and can be completely degraded, saving materials and realizing a circular economy. In this embodiment, the bottom support 1, the flap 3, and the stepped protrusion 4 are integrally formed, which facilitates processing and manufacturing, reduces the overall volume of the product packaging box, saves energy and materials, and improves the comprehensive utilization rate , Greatly reduce product packaging costs and product transportation costs.
