Description

Technical Field

[0001] This utility model relates to the field of paper-plastic technology, and in particular to a paper-plastic structure with high fitting tightness. Background Technology

[0002] Chinese Patent Publication No. CN 220866007 U, published on April 30, 2024, discloses a paper-plastic packaging structure for an oven. The structure includes an upper tray and a lower tray. The upper tray has a first decorative element and a first load-bearing element, with the first load-bearing element embedded within the first decorative element. The lower tray has a second decorative element and a second load-bearing element, with the second load-bearing element embedded within the second decorative element. The first and second decorative elements are positioned opposite each other at opposite ends of the oven. This invention packages the oven between the first and second decorative elements. The first load-bearing element is embedded within the first decorative element, increasing its structural strength. The lower tray has a second decorative element and a second load-bearing element, which is also embedded within the second decorative element, further increasing the structural strength of the first decorative element. This design increases the structural strength of the upper and lower trays while reducing the volume of the paper-plastic cushioning packaging, increasing container capacity, and lowering transportation costs. The existing technology has the following drawback: the protruding edge on the open side of the load-bearing component typically abuts against the inner wall of the packaging box. However, due to the weak elasticity of the paper-plastic material, deformation of the protruding edge affects the stability of the product. To compensate for this stability deficiency, additional cushioning components are added during daily use to ensure the product does not shift, which complicates the internal structure of the packaging. Therefore, an improvement is urgently needed. Utility Model Content

[0003] Based on this, the purpose of this utility model is to provide a paper-plastic structure with high fitting tightness, with an auxiliary reset structure at the protruding edge to reduce the probability of deformation of the protruding edge and improve the fitting tightness between the paper-plastic and the inner cavity of the packaging box.

[0004] This utility model provides a paper-plastic structure with high fitting tightness, including a paper-plastic body, the upper surface of which has a raised edge formed around the opening, and an auxiliary reset structure; the auxiliary reset structure includes a rectangular ring and a corrugated paper layer circumferentially formed on the outer side of the rectangular ring; the raised edge is circumferentially folded to form an inclined pressing surface; the auxiliary reset structure is correspondingly sleeved on the upper part of the outer side of the paper-plastic body and its position corresponds to the raised edge, and the crest of the corrugated paper layer contacts the inner side of the inclined pressing surface.

[0005] Preferably, the inner surface of the paper-plastic body is formed with a decorative velvet layer.

[0006] Preferably, finger clearance grooves are formed on the upper parts of opposite sides of the paper-plastic body in the width direction.

[0007] Preferably, the rectangular ring body is interference-fitted with the outer surface of the paper-plastic body.

[0008] Preferably, the inner and outer walls of the paper-plastic body are both reinforced with ribs.

[0009] The beneficial effects of this utility model are as follows: by setting an auxiliary reset structure, the crest of the corrugated paper layer contacts the inner side of the inclined pressing surface, and the corrugated paper layer provides a supporting reset force to the inclined pressing surface, reducing the probability of deformation of the convex edge and improving the tightness of the fit between the paper and the inner cavity of the packaging box.

[0013] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with specific embodiments and accompanying drawings.

[0014] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] Please refer to Figure 1-2As shown, this utility model provides a paper-plastic structure with high fitting tightness, including a paper-plastic body 10. A raised edge 11 is formed on the upper surface of the paper-plastic body 10 around the opening. It also includes an auxiliary reset structure 16. The auxiliary reset structure 16 includes a rectangular ring 14 and a corrugated corrugated paper layer 15 circumferentially formed on the outer side of the rectangular ring 14. The raised edge 11 is circumferentially folded to form an inclined pressing surface 12. The auxiliary reset structure 16 is correspondingly fitted onto the upper part of the outer side of the paper-plastic body 10 and its position corresponds to the raised edge 11. The crests of the corrugated corrugated paper layer 15 contact the inner side of the inclined pressing surface 12. The rectangular ring 14 is interference-fitted with the outer side of the paper-plastic body 10.

[0016] The inner surface of the paper-plastic body 10 is formed with a decorative velvet layer, which enhances the decorative effect and gives users a good visual experience and tactile feel.
