Problems solved by technology

This is due to the fact that rods, sheets, strips or other simple shapes of packaging fillers cannot form an effective "hook" combination, and are dislocated under the influence of shock and vibration during transportation, resulting in changes in the migration of the packaged objects. ;The migration of the product position will change the protected state of the packaged product in transportation and circulation, and lose the proper protection under the subsequent impact and vibration
[0003] Because the structure of the existing loose filler is close to rod shape, sheet shape, strip shape and limited deformation, it cannot effectively fix the packaged product in the packaging container, so the packaged product will be affected by shock and vibration during transportation and circulation. The protected state of the product will be changed due to the migration of the position; while the loose filler with the same shape has no size specification change, and the range of the filling space is small, which reduces the scope of adaptation to the protection of the packaged object.

Embodiment 1

[0023] A kind of packaging loose-fill structure embodiment, see Figure 1 to Figure 3 , the filler structure includes a semi-arc-shaped shell 1, along the outside of the semi-arc-shaped shell, along the bottom, outward and upward, there are a plurality of curved wings 2 composed of space curved surfaces 2-1, so A rib-shaped protrusion 3 is provided on one side of the curved surface of the wing, and a groove 1-1 is provided on the top of the semi-arc-shaped shell.

[0024] The curled wing-like structure forms a "hook" shape, which makes the loose-fill structure generate hook chain nesting effect between materials during random filling, avoiding the migration of packaged products caused by the movement between loose-fill materials, and obtaining reliable The buffer protection function.

[0025] In order to obtain the best hook chain effect, the unfolded shape of the curved wings is a gourd shape with a narrow front and a wide rear, and the end surface 2-2 is a circular arc. The...

Embodiment 2

[0031] A kind of embodiment of connecting row of loose packing structure for packaging, see Figure 4 And embodiment 1, the connecting row is composed of a plurality of loose-fill structures for packaging according to embodiment 1 arranged along a plane, and the loose-fill structures for packaging include a semicircle-shaped shell, along a semicircle The arc-shaped shell is extended outward and upward along the bottom with a plurality of curved wings made of space curved surfaces 2-1. One side of the curved surface of the wings is provided with rib-shaped protrusions. The top of the arc-shaped shell is provided with a groove.

[0032]There are three curved wings extending upward along the bottom of the semi-circular arc-shaped shell, and the three curved wings are arranged at an angle of 120 degrees around the semi-circular arc-shaped shell; The unfolded shape is a gourd shape with a narrow front and a wide rear, and an arc-shaped end face. The upward bending radius of curvat...

Abstract

The invention relates to a loose filler structure body for package and a connecting bar thereof. The loose filler structure body comprises a semicircular arc-shaped shell. A plurality of curved spread wings are bent and extend outwards and upwards along the bottom of the outer edge of the semicircular arc-shaped shell; one side surface of the curved surface of the spread wing is provided with a rib-shaped boss; and the top part of the semicircular arc-shaped shell is provided with a groove. In the loose filler structure body, the semicircular arc-shaped shell can effectively bear an external force load; the structure with the curved spread wings can realize hooking and embedding of loose filler structure bodies, so that the transfer and the change of the positions of packaged products in a packaging container in the process of transportation and circulation due to vibration are avoided, the condition that the packaged products are effectively fixed by the loose filler structure bodiesis guaranteed, and further the buffering-package protecting function is guaranteed for the packaged products. The loose filler structure body is especially suitable for molded forming of degradable materials such as paper fiber, starch or polylactic acid and the like, thermoplastic materials or metallic materials.

Description

technical field [0001] The invention belongs to the field of packaging materials, in particular to a loose packing structure for packaging and a connecting row thereof. Background technique [0002] Loose-fill packaging materials are used to cushion and protect products during transportation and circulation. The loose-fill materials currently used for cushioning packaging include loose-fill materials that use cardboard as raw materials and are bent and formed into heart-shaped structures. Loose cushioning and filling material made of expanded polystyrene foam material; loose filling material made of cardboard as raw material is made of cardboard with a specified width after cutting, forming, and bonding; expanded polystyrene foam The loose cushioning packaging material made of polystyrene foam material is formed into granular loose material. The above-mentioned existing product structures are close to rod shape, sheet shape, strip shape and limited deformation, and are used...
