Pop can cap structure
Technical field
The utility model relates to pop can cap structure.
Background technology
Pop can is a kind of common manner of packing.In order to provide the commodity information of food or drink, usually bar code can be printed at the body of packing foods or drink or can body.Bar code (barcode) is the multiple secret note and blank that are not waited by width, according to the arrangement of certain coding rule, in order to express the graphical identifier of one group of information.Common bar code is the pattern of parallel lines that the secret note that differed greatly by reflectivity and informal voucher are lined up.Bar code can store goods information.The defect that bar code exists is that to store information limited, is usually mainly used in logistic industry and various sales field, and usually used as the use of stock and sale buret.Along with social development, the more and more rich and varied change of commodity information, also tend to facilitates customer's quick search more simultaneously.
If suitably can improve the packaging of pop can, enable to store comparatively multiple data quantity, convenient inquiry again, then necessarily have good market outlook simultaneously.
Summary of the invention
The utility model is for the problems referred to above, and provide a kind of pop can cap structure, this cap structure can store more commodity information.
According to the technical solution of the utility model: a kind of pop can cap structure, comprise top cover, described top cover top is provided with recessed district, closure plate is formed by closed line of weakness in recessed district, pulling-on piece is connected with closure plate by rivet, it is characterized in that: described pulling-on piece has the region for the formation of readable matrix code away from rivet one side surface, and this region comprises recess, protuberance.
As further improvement of the utility model, described readable matrix code is arranged at pulling-on piece upper surface.
As further improvement of the utility model, described readable matrix code is arranged at pulling-on piece lower surface.
As further improvement of the utility model, the junction of described pulling-on piece and rivet is provided with draw ring hole.
Technique effect of the present utility model is: the utility model product structure is simple, reasonable in design ingenious, and pop can top cover in use can be made can to store more commodity information.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further described.
In Fig. 1, comprise top cover 1, recessed district 2, closure plate 3, pulling-on piece 4, draw ring hole 4-1, readable matrix code 4-2, recess 4-3, protuberance 4-4, rivet 5, line of weakness 6 etc.
As shown in Figure 1, the utility model is a kind of pop can cap structure, comprise top cover 1, described top cover 1 top is provided with recessed district 2, closure plate 3 is formed by closed line of weakness 6 in recessed district 2, pulling-on piece 4 is connected with closure plate 3 by rivet 5, and described pulling-on piece 4 has the region for the formation of readable matrix code 4-2 away from rivet 5 one side surface, and this region comprises recess 4-3, protuberance 4-4.
Readable matrix code 4-2 can be arranged at upper surface or the lower surface of pulling-on piece 4; Pulling-on piece 4 is provided with draw ring hole 4-1 with the junction of rivet 5.Owing to arranging readable matrix code 4-2, the position of this draw ring hole 4-1, near rivet 5 side, is arranged at draw ring hole 4-1 in prior art and has larger difference away from rivet 5 position.
The method that in the utility model product, readable matrix code 4-2 can be " CN103718195A " patent disclosure by publication number forms readable matrix code 4-2 on top cover 1.Readable matrix code 4-2 by laser printing or spray printing in specific region, top cover 1 top, i.e. the region that formed of recess 2-1 and protuberance 2-2.The readable matrix code formed by above-mentioned patented method can by smooth and easy reading on on-plane surface, and this readable matrix code all can be successfully read on image, picture in addition, namely also can normally read under polyenergetic background.Owing to adopting this readable matrix code, can on the pulling-on piece 4 of pop can top cover first spray printing pattern, and then laser printing or spray printing readable matrix code, the readable matrix code obtained effectively can be read by all kinds of barcode scanning equipment.
The setting of the readable matrix code 4-2 in the utility model product is according to the direct spray printing of maturation method conventional at present or print on pulling-on piece 4.
