Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper-plastic inner packaging technology, and in particular to an inner packaging structure based on corrugated springs. Background Technology
[0002] Paper-plastic lining packaging structures are widely used in the market for packaging fragile electronic products such as monitors and laptops. They can support and protect the products during transportation, preventing them from being damaged by rigid impacts.
[0003] The problem is that even within the same product category, such as monitors, which include 27-inch, 24-inch, 22-inch, and 21.5-inch models, the variety of product specifications and inconsistent shipment volumes necessitate a significant investment of engineering and technical personnel in the design and development of paper-plastic liner packaging. Each product requires a corresponding paper-plastic liner mold design, mold making, and trial molding, resulting in long development cycles, high manpower investment, and high costs. Utility Model Content
[0004] This application addresses the shortcomings of the prior art by providing an inner packaging structure based on a corrugated spring. The main structure is a long, folded or rectangular shape, with a corrugated spring structure in the middle of the main fixed part. Through the corrugated form, the structure deforms according to the principle of a spring, thereby changing the dimensions of the inner packaging in the length and width directions, thus adapting to various product packaging specifications.
[0005] The technical solution adopted in this utility model is as follows:
[0006] A corrugated spring-based inner packaging structure is characterized by comprising at least four supporting bodies for enclosing the product. The main supporting inner lining is enclosing the product along its length, and the side supporting inner lining is enclosing the product along its width. The middle of each main supporting inner lining is connected to both ends by a stretchable corrugated paper-plastic joint. The middle of each side supporting inner lining is either a disconnected structure or is composed of a stretchable corrugated paper-plastic joint connecting both ends. The inner packaging structure adaptively adjusts the product enclosure size in both length and width degrees of freedom through the corrugated paper-plastic joint or disconnected design.
[0007] Furthermore, the inner packaging structure consists of two folded paper-plastic assemblies. Each folded paper-plastic assembly unfolds in a straight line and includes two main bodies in the middle, corrugated paper-plastic connecting the two main bodies, and side ears connected to one side of each main body. Each side ear and the main body of each main body has a packaging slot for placing the product inward in the middle. Adjacent side ears and main bodies are connected by a folding structure.
[0008] Furthermore, when each of the folded paper-plastic assemblies is in the closed state, the side ears are vertically bent to the main body through the folding structure. The two main bodies and the corrugated paper-plastic in the middle constitute the main support liner. The two sets of parallel folded paper-plastic side ears are designed to be disconnected. The set of side ears that are disconnected from each other constitutes the side support liner.
[0009] Furthermore, the cross-section of the corrugated paper-plastic is a spine-corrugated type.
[0010] Furthermore, the cross-section of the corrugated paper-plastic is a grooved corrugated type.
[0011] Furthermore, the cross-section of the corrugated paper-plastic is a disc-shaped corrugation.
[0012] Furthermore, the cross-section of the corrugated paper-plastic is longitudinally corrugated.
[0013] Furthermore, the cross-section of the corrugated paper-plastic is a straight-line corrugation.
[0014] Furthermore, the inner packaging structure includes two mutually cooperating upper support structure and lower support structure. Each upper support structure and lower support structure includes four L-shaped bottom supports. The bottom supports arranged along the product length direction are connected by corrugated paper and plastic, and the bottom supports arranged along the product width direction are connected by corrugated paper and plastic. The two bottom supports in the length direction combined with the corrugated paper and plastic form the main support inner lining, and the two bottom supports in the width direction combined with the corrugated paper and plastic form the side support inner lining.
[0015] Furthermore, each bottom support of the upper support structure has an L-shaped cross-section packaging groove formed on its lower surface, and the packaging groove has at least three positions on its edge that are formed with limiting teeth.
[0016] The inner surface of each base of the lower support structure is formed with a support groove of L-shaped cross section, and a corresponding number of mating grooves are formed at the position of the limiting tooth corresponding to the support groove.
[0017] The beneficial effects of this utility model are as follows:
[0018] Compared to existing technologies, the inner packaging structure provided by this utility model includes a folding structure and an upper and lower support structure. The main structure of the folding inner packaging structure is long and narrow, with a corrugated spring structure in the middle of the fixing part and 90° rotating latches at both ends. The main structure of the upper and lower support type is a U-shaped rectangle, with components divided into an upper support and a lower support. Each component has a corrugated spring structure in the middle, and the upper and lower supports are fitted with latches. Compared to the existing single-specification inner packaging structure design that is only applicable to one model, this utility model has strong versatility and is applicable to multiple models. It can reduce development costs, shorten development cycles, be applicable to multiple models, and reduce warehousing costs. It also reduces design, mold making, prototyping, testing and other processes, and reduces warehousing materials. Attached Figure Description
