Description

Technical Field

[0001] The utility model relates to the technical field of packaging, and more particularly to an inner liner for carton packaging, in particular to an inner liner for a tubular article packaging box. Background Art

[0002] Bulk transportation of tubular articles is usually carried out through transport boxes. In order to prevent the movement of tubular articles during transportation and to prevent the collision of tubular articles with each other, resulting in damage and scratches, etc., lining is usually added to the transport box to separate the parts. For aluminum tubes, aluminum rigid tube packaging mostly uses paper lining partitions to prevent the aluminum tubes from being bumped and damaged on the outer surface during transportation, while also limiting the displacement of the tube body and preventing the center of gravity of the box from shifting. The paper lining partition is made of cardboard as raw material and is manually assembled and inserted into shape. For example, in the disclosed Chinese patent application, publication number: CN219134875U, patent name: A packaging box lining, although the overall stability during use and transportation is increased by fixing the bottom plate and the lining grid, the original lining material, size and other parameters are not changed, saving some material investment. However, this prior art has the disadvantages of cumbersome assembly process, low material reuse rate and low boxing efficiency.

[0003] In the published Chinese patent application, the publication number is CN207242342U, and the patent name is: A lining structure for a strip-shaped tubular article packaging box. Although the lining structure is formed by stacking multiple layers of support plates to form a support member, a multi-layer accommodating layer is formed, and corresponding support grooves are set on the support plates to form support for both ends of the strip-shaped tubular articles such as rolls of paper and rolls of skin, thus forming an effect of carrying multiple layers of products, and each layer can stably store multiple products through the setting of support grooves. However, the prior art uses two vertically arranged support members at both ends to support and lift the two ends of multiple horizontally arranged strip-shaped tubular articles. Since the support members and the strip-shaped tubular articles are not effectively fixed, the support members are easily tilted due to the impact of road bumps and braking inertia during transportation, resulting in an imbalance of force at both ends of the strip-shaped tubular articles, causing damage to the strip-shaped tubular articles.

[0004] In summary, the problems existing in the prior art are: problem 1, the assembly process is cumbersome, the material reuse rate is low, and the boxing efficiency is low; problem 2, the lining structure cannot effectively support and fix the tubular articles after being affected by external forces. In order to solve the problems existing in the prior art, this application is specially proposed to solve them. Utility Model Content
