Label constructing method for labeling at low-lying parts of deeply recessed containers

Abstract

The invention relates to a label constructing method for labeling at low-lying parts of deeply recessed containers. The label constructing method is characterized in that in order to prevent a two-dimensional code on a packaging container from being read through stealing before a consumer purchases a product, improve code identification sensitivity and prevent the product in the container from being contaminated by printing ink, the adopted label structure for the deeply recessed containers is formed by the steps of: arranging optically readable code on the back surface of a transparent thin film, and printing a background printing ink layer on the code, wherein the size of the background printing ink is larger than the code area and is smaller than a die cutting portion or the low-lying parts of the deeply recessed containers; spraying a non-setting adhesive layer larger than the background area on the background printing ink layer; and spraying a silicone oil on the non-setting adhesive, and adhering a protective layer on the silicone oil. The label constructing method can realize high-speed mass tagging on bottle caps or deeply recessed containers which are generally impossibleto be tagged, and can prevent the food and beverage from being contaminated by the printing ink.

Description

【Technical Field】 [0001] The invention belongs to a method for labeling a mark on a low-lying part of a recessed container in the field of image processing. 【Background technique】 [0002] With the concrete application of the concept of the Internet of Things, people finally see the practicality of de-conceptualization with low investment and quick results, which is between the popular mobile phone reading to connect products to the Internet to realize product promotion. technology. [0003] Therefore, regardless of the product, the realization of mass mobile phone identification through variable information coding has become a trend, but how to perform product coding with high efficiency and low cost has become a topic of attention. [0004] For this reason, in the past year or so, there have been many publications of patents related to this aspect. In China, the German coding professional Domiruo Company published a report entitled "A bottle cap with a QR code on the top or side o...

AI Technical Summary

Problems solved by technology

[0017] The first purpose of the present invention is to solve the problems of low coding efficiency of lasers, large restrictions on coding materials, and low coding quality that is not easy to identify, especially for bottle caps that have been produced, especially for brand companies. A product that cannot be changed, providing a solution to all the problems caused by the current laser coding through the direct coding process without changing the existing bottle cap material and structure

[0019] The third purpose of the present invention is: to provide a method of spraying protective film to solve the problem that jet printing ink cannot contact beverage or food
