Product example 1
Referring to fig. 3, which is a schematic cross-sectional view of a first cushioning structure for packaging of the present invention, in one embodiment of the present invention, a cushioning structure 10 for packaging is provided, which includes at least one base material layer 11 and at least one cushioning layer 12. The substrate layer 11 is a sheet, for example, a support sheet. The buffer layer 12 includes a plurality of hollow tubes 12A fixedly disposed on one side surface of the substrate layer 11.
The hollow tube 12A extends along the axial direction thereof, and the axial direction of the hollow tube 12A is parallel to the plane of the base material layer 11. That is, each hollow tube 12A is disposed along the surface of the base material layer 11, extending in the axial direction.
In a preferred embodiment of the present invention, as shown in fig. 1, in the consent buffer layer 12, a plurality of hollow tubes 12A are arranged in parallel with each other.
In a specific embodiment of the present invention, the cross section of the hollow tube 12A is a hollow circle, a hollow ellipse, a hollow fan shape or their approximate shape, that is, the hollow tube 12A may be a hollow cylindrical tube or an approximate cylindrical tube, an elliptical cylindrical tube or an approximate elliptical cylindrical tube, a fan shape tube or an approximate fan shape tube, etc., wherein the hollow cylindrical tube is the most ideal case, and in application, may be adjusted according to practical situations.
In a preferred embodiment of the invention, the outer diameters (outer diameters) of the plurality of hollow tubes 12A are all the same buffer layer 12.
In the buffer structure for packaging of the present invention, a plurality of hollow tubular objects 12A arranged in parallel are fixedly arranged on a base material layer 11 to form a buffer layer 12; when the structure is subjected to external force, the hollow tubular object 12A deforms and rebound resilience is generated, so that the buffer performance is provided for the whole packaging product, and the impact force of the external force on the content is relieved; when the buffer structure for packaging is specifically applied, the deformation degree and whether the buffer structure is damaged or not can be used for judging the violent transportation condition; in addition, paper, PLA, natural fiber or other degradable materials can be adopted to realize the packaging buffer structure, so that the environment-friendly packaging buffer product is obtained.
In a preferred embodiment of the present invention, in the same buffer layer 12, the minimum distance X between adjacent hollow tubular objects 12A is greater than zero and less than or equal to the outer tube radius d of the hollow tubular objects 12A.
With the packing cushioning structure of the preferred embodiment, when it receives an external force, the hollow tubular member 12A is deformed to some extent; when the deformation is continuous and reaches a certain degree, the adjacent hollow tubular objects 12A are mutually abutted, and then a supporting force is generated between the adjacent hollow tubular objects, so that the external force can be resisted, and the adjacent hollow tubular objects are prevented from being flattened to a certain degree; when the external force is removed, the counteracting/supporting forces between adjacent hollow tubular objects can promote their rebound again; the inventor finds out in the research and development process that a certain gap needs to be reserved between the adjacent hollow tubular objects 12A so as to provide a certain space for the deformation of the hollow tubular objects 12A when stress is applied, provide a buffering margin and prevent the whole buffer layer from being too hard; in addition, the gaps (minimum intervals) between the adjacent hollow tubular objects 12A are smaller than or equal to the radius, so that the hollow tubular objects 12A can be guaranteed to be mutually abutted before being completely flattened, a supporting force is generated between the hollow tubular objects, the external force can be supported and resisted, resilience is promoted, and good buffering performance is provided for the whole packaging product.
In a preferred embodiment of the present invention, when the hollow tubular objects 12A in the buffer layer 12 are made of paper, the minimum distance X between adjacent hollow tubular objects 12A in the same buffer layer 12 is greater than zero and less than or equal to the outer tube radius d of the hollow tubular objects 12A.

Regarding the fixing manner of the hollow tubular objects 12A and the base material layer 11, in a preferred embodiment of the present invention, in the buffer layer 12, the hollow tubular objects 12A are fixed on one side surface of the base material layer 11 by means of adhesion, for example, each hollow tubular object 12A may be formed by separate processing and then sequentially adhered and fixed on one side surface of the base material layer 11, for example, a plurality of hollow tubular objects 12A may be formed directly by processing and fabricating folding lines according to a predetermined dimension on a sheet material and then pressing inward (in actual production, the tube wall of the hollow tubular object 12A may leave an unsealed gap), and then the whole body thereof is adhered to one side surface of the base material layer 11.
In particular, in this embodiment, as shown in fig. 3, the packaging cushioning structure 10 includes a base material layer 11 and a cushioning layer 12; the buffer layer 12 comprises a plurality of hollow tubular objects 12A which are arranged in parallel and are adhered and fixed on one side surface (the upper surface shown in fig. 3) of the substrate layer 11; in the buffer layer 12, the outer tube diameters of the plurality of hollow tubes 12A are uniform, and the minimum distance X between adjacent hollow tubes 12A is greater than zero and equal to or less than the outer tube radius d of the hollow tube 12A.
