Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1a, the present invention provides a plastic packaging lining, which combines plastic and film to provide a protective package for a product, so as to improve the versatility of the packaging structure without increasing the cost.
The plastic packaging lining mainly comprises two parts, namely a plastic lining component and an elastic film 2, as shown in figure 2a, the plastic lining component comprises a quadrilateral lining base plate 10, the lining base plate 10 is provided with a first side edge, a second side edge, a third side edge and a fourth side edge which are sequentially connected, wherein the first side edge is opposite to the third side edge, and the second side edge is opposite to the fourth side edge; the utility model also comprises a first side plate 11 connected with the first side edge and a third side plate 13 connected with the third side edge; in order to facilitate the adaptation of the product to be packaged, a shallow groove M is formed on one side of the surface of the inner substrate sheet 10.
The elastic film 2 is disposed on one side of the surface of the lining bottom plate 10 (i.e., the side formed with the shallow groove M), the elastic film 2 can cooperate with the shallow groove M to form a containing space for containing a product, and specifically, two ends of the elastic film 2 are respectively connected to the first side plate 11 and the third side plate 13. The first side plate 11 and the third side plate 13 are folded back to the side away from the elastic film 2 relative to the lining bottom plate 10, the elastic film 2 with two ends connected to the first side plate 11 and the third side plate 13 is stretched in the process, the product between the elastic film 2 and the surface of the lining bottom plate 10 is pressed onto the shallow groove M by the elastic potential energy of the elastic potential energy to be limited, and the elastic film 2 and the shallow groove M on the lining bottom plate 10 provide powerful fastening effect for the product.
In a preferred form, as shown in fig. 1b, the plastic liner assembly may further include a second side panel 12 attached to the second side edge of the bottom panel 10 and a fourth side panel 14 attached to the fourth side edge of the bottom panel 10. The second side plate 12 and the fourth side plate 14 are folded relative to the inner bottom plate to the side away from the back surface of the lining bottom plate 10, and form a space on the side of the surface of the lining bottom plate 10 to protect the product on the side of the surface of the lining bottom plate 10. Fig. 2a shows a plan expanded view of the plastic package liner, and fig. 2b shows a perspective structural view of the plastic package liner.
Of course, the lining bottom plate 10, the first side plate 11, the second side plate 12, the third side plate 13 and the fourth side plate 14 are all made of plastic, and may be specifically made of paper plastic, PET (polyethylene terephthalate) or PS (polystyrene).
Taking the plastic packaging lining shown in fig. 1b as an example, when packaging, as shown in fig. 3a, a product is placed between the elastic film 2 and the shallow groove M, the shallow groove M has a certain limiting effect on the product, then as shown in fig. 3b, the first side plate 11 and the third side plate 13 are folded back to the side away from the elastic film 2 relative to the lining bottom plate 10, the elastic film 2 with two ends connected to the first side plate 11 and the third side plate 13 is stretched in the process, the elastic potential energy of the elastic potential energy presses the product between the elastic film 2 and the surface of the lining bottom plate 10 to the shallow groove M to limit the product, and the elastic film 2 and the shallow groove M on the lining bottom plate 10 provide a powerful fastening effect for the product; next, as shown in fig. 3c, the second side plate 12 and the fourth side plate 14 are folded back relative to the inner bottom plate to a side away from the back surface of the lining bottom plate 10, and both form a space on the side of the surface of the lining bottom plate 10 to protect the product on the side of the surface of the lining bottom plate 10.
It can be seen that, above-mentioned plastic packaging inside lining in use, shallow mouthful groove M plays certain limiting displacement to the product, and elastic film 2 and inside lining bottom plate 10's shallow mouthful groove M can provide firm and safe guard action for the product, because elastic film 2's existence, shallow mouthful size of groove M can not be injectd by the product specification, can adapt the not unidimensional product, has saved manufacturing cost. Moreover, the film packaging protective lining is simple in structure, stable in protection and good in development prospect.
In particular, there are various implementations regarding the formation of the shallow slot M, as exemplified below.
Example 1
The shallow groove is formed by the lining bottom plate 10 being recessed towards the side facing away from the flexible membrane 2, and fig. 4a shows a cross-sectional view a-a of the structure of the shallow groove M in the flat developed configuration shown in fig. 2 a. The specific recess can be formed by injection molding, plastic suction molding and other processes.
Example two
The backing plate 10 forms an annular projection N towards the side on which the elastic membrane 2 is arranged, as shown in fig. 4b, which shows a cross-sectional view a-a in fig. 2a of such a shallow groove M, which is formed between the annular projection N and the surface of the backing plate 10. In one possible implementation manner, based on the structure shown in fig. 4b, the annular boss N may have a gap Q, so as to save material on the basis of forming the shallow slot M, as shown in fig. 4 c.
It should be noted that the plastic liner assembly with different shaped shallow slots M shown in fig. 4a to 4b is configured as shown in fig. 2a in a plan view.
In order to further improve the stretching and fastening effect of the elastic film 2, the elastic film 2 in this embodiment is provided with a plurality of stretching hole structures, and when the elastic film 2 is stretched, the stretching hole structures return to a certain concave-convex state relative to the plane where the elastic film 2 is located under the action of a tensile force, so that the roughness of the elastic film 2 is increased, and the clamping and fixing effect on a product is enhanced.
The length of the elastic film 2 along the direction from the first side plate 11 to the third side plate 13 needs to be defined according to the size and shape of the product to be packaged, and preferably, the length of the elastic film 2 in the direction is only longer than the length of the lining bottom plate 10.
In addition, in the embodiment, the elastic film 2 is made of thermoplastic polyurethane elastomer rubber, so that the elastic film has the advantages of high strength, high toughness and wear resistance, and can provide a better fastening effect for a product.
Based on the same invention thought, the embodiment of the utility model also provides a packing box, including the box body and any kind of film packing protective lining that the embodiment provided as above, film packing protective lining sets up in the box body, can provide good fixed protective effect for the product.
It will be apparent to those skilled in the art that various changes and modifications may be made to the embodiments of the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
