As shown in Figure 1 and Figure 2, Fig. 1 is the sectional view of the individual packaging unit of the embodiment of the application one, and Fig. 2 is the application reality Apply the top view of the packaging structure of example.The present embodiment provides packaging structure to be used to be made product packaging, and product packaging is used for filling Fluid food, such as milk, Yoghourt, so that fluid food is transported and is sold.The product that the packaging structure provided by the application is made Product packaging ensure that product is not in that Quick Response Code is stolen situation about sweeping before sale.
Specifically, packaging structure has multiple individual packaging units 100, each individual packaging unit 100 includes base material 10, First paster 20 and one second paster 30, wherein, the base material 10 of each individual packaging unit 100 has a through hole 101 and a two dimension Code 102.
First paster 20 is fixed on the one side of base material 10, for covering through hole 101 and at least partly Quick Response Code 102.Two Dimension code 102 cannot be identified equipment and distinguish out information when being covered by the part of the first paster 20.
Second paster 20 is fixed on the another side of base material 10, for covering through hole 101.
Specifically, the base material of each individual packaging unit is integrally formed.
Quick Response Code can be the Quick Response Code of any standard, and the Quick Response Code on each individual packaging unit is different.
Through hole can be circular hole, elliptical aperture etc., and the application is not construed as limiting to the concrete shape and size of through hole.
First paster and the second paster can be square, rectangle, circle or irregular figure etc., and the application is to first The concrete shape and size of paster and the second paster are not construed as limiting.In order to increase interest, can also be in the first patch figure printed on chip Case, product operation instruction etc..
Second paster is used for proof strength and sealing, prevents through hole from easily being ruptured because extruding or shaking.First Paster is used to supply user's pull-up, so as to obtain through hole.Optionally, for the ease of the first paster on user's pull-up through hole, first At least part of fringe region of paster is not fixed on base material.
In some implementation methods, in order to avoid the first paster is oversized because of covering Quick Response Code, so that waste of materials, two Dimension code is arranged at around through hole.
In some implementation methods, the first paster and the second paster can be fixed by way of hot pressing.In other embodiment, First paster and the second paster can also be fixed by gluing mode.The application is to the specific fixation side of the first paster and the second paster Formula is not construed as limiting, and can be used as long as not influenceing the mode of food security.
In some implementation methods, the first paster and the second paster are bonded to each other in through hole, so that in pull-up first The second paster can be simultaneously pulled open during paster, packaging is opened through hole and is opened wide.
In some implementation methods, the first paster includes aluminium foil layer and PE layers, and the aluminium foil layer is located at the PE layers of top.Second Paster includes PE layers.
In some implementation methods, base material is made up of basic unit, printing layer and waterproof layer, and printing layer is located at the top of basic unit, is prevented Water layer is located at the top of printing layer;Quick Response Code is arranged in printing layer.Other regions of printing layer are printed with the information of product, example Such as, advertisement design pattern, production relevant information etc..
Further, base material also includes gas barrier layer and sealant layer, and gas barrier layer and sealant layer are sequentially located under basic unit Side.
In some implementation methods, base material includes basic unit, printing layer, the first waterproof layer, coating and the second waterproof layer.Printing layer Positioned at the top of basic unit, the first waterproof layer is located at the top of printing layer, and at least part of region is coated with coating on the first waterproof layer, Spray printing has Quick Response Code or is pasted with two-dimension code label on coating, and the second waterproof layer is located at Quick Response Code or two-dimension code label top.
As shown in figure 3, flow charts of the Fig. 3 for the packaging structure production method of the embodiment of the present application.Specifically, method bag Include:
Step 301:The base material that production has the base material of multiple individual packaging units, each individual packaging unit has a two dimension Code.During specific implementation, the Quick Response Code on each individual packaging unit is different.
Step 302:A through hole is made on the base material of each individual packaging unit.
Step 303:First paster is fixed on the one side of base material, so that the first paster covering through hole and at least part of two Dimension code.
Second paster is fixed on the another side of base material, so that the second paster covering through hole.
During specific implementation, the first paster and the second paster can be also secured on the base material of individual packaging unit;Or first will First paster is fixed on the one side of base material, then the second paster is fixed on the another side of base material;Or first consolidate the second paster The another side of base material is scheduled on, then the first paster is fixed on the one side of base material.
Describe the detailed process of step 302 and step 303 in detail with a specific embodiment below.
The base material 10 that step 301 is produced is placed on production line shown in Fig. 4.Base material 10 is constantly transmitted by motor, is beaten Aperture apparatus 401 make a call to a through hole every Fixed Time Interval on base material;Or punched according to punching instruction, punching instruction Produced according to the witness marker (witness marker can be recognized by inductor) on individual packaging unit by controller.Paster sticker 402 paste the first paster and the second paster so that the first paster and the second paster covering one every Fixed Time Interval on base material Through hole;Or pasted according to instruction is pasted, stickup instruction is produced by controller according to the witness marker on individual packaging unit It is raw.First paster is brought into close contact in through hole with the second paster by hot pressing, so that can be in the first paster of pull-up simultaneously The second paster is pulled open, packaging is opened through hole and is opened wide.
As shown in Figure 5, Figure 6, Fig. 5 and Fig. 6 is the product packaging schematic diagram of the embodiment of the present application, and the product packaging is using upper The individual packaging unit stated in the packaging structure described in any embodiment is made.
Specifically, the product packaging described in the present embodiment can be standard cuboid, or be middle concave or convex Polyhedron, the application is not limited its concrete shape.
User can open through hole by way of the paster of pull-up first, while obtaining Quick Response Code, can effectively prevent Bacterium is set to enter in product because insertion suction pipe opens through hole.Separately, at least part of region of two-dimension code structure is covered by the first paster Lid, is prevented from product and occurs Quick Response Code before sale being stolen the situation for sweeping failure, and (code is product bag to protection consumer barcode scanning The Quick Response Code loaded onto) participation activity rights and interests.
The above is merely to illustrate the technical scheme of the application, any those of ordinary skill in the art can without prejudice to Spirit herein and under the scope of, above-described embodiment is modified and is changed.Therefore, the rights protection scope of the application should be regarded Right is defined.
