[0002] Chinese patent 200520060562.1 discloses an L-shaped paper corner protector, which includes an L-shaped hollow paper tube and a corrugated cardboard core set inside the L-shaped hollow paper tube for support. The number of corrugated waves of the cardboard core is one or more. In addition, Chinese patent 200620057785.7 also discloses "a reinforced paper corner protector for paper packaging boxes", which is an L-shaped cardboard made of multi-layer cardboard , the inside of the L-shaped cardboard is provided with a metal support body, and the metal support body is a metal sheet or a metal mesh. The purpose of the above two technical solutions is to provide a paper corner protector with good compression and impact resistance, but the former uses The technical scheme of setting a corrugated cardboard core in the hollow paper tube is obviously difficult to ensure the compressive and impact strength when encountering products with heavy packaging weight. The method of attaching a metal support body in the cavity can achieve the above-mentioned purpose, but it will increase the cost in terms of technology and production.

Embodiment Construction

[0009] As shown in Figures 1 and 2 of the present invention, a paper corner protector includes a base body 1 with an L-shaped cross-section. The base body 1 is composed of an outer corner plate 11 and an inner corner plate 12. The outer corner plate is a hard plate. The above-mentioned inner corner boards are honeycomb paperboards, and the inner and outer corner boards 11 and 12 are bonded.

[0010] The above-mentioned outer corner plate 11 can be pressed and formed by hard board, and can also be made of fiberboard or other hard materials. The outer corner plate 11 can not only offset the force from the vertical direction, but also its two ends can be subjected to lateral force. Always maintain the rigidity of the paper corner. In addition, the outer corners of the above-mentioned outer corner plates can be designed as right angles or arc-shaped corners according to the shape of the outer packaging box and the inner package. Similarly, the above-mentioned inner corner plates c...
