技术领域Technical Field
本实用新型涉及防伪标签技术领域，具体为一种食品变色防伪标签。The utility model relates to the technical field of anti-counterfeiting labels, in particular to a food color-changing anti-counterfeiting label.
背景技术Background Art
防伪标签是能粘贴、印刷、转移在物体的表面上，具有防伪作用的标识，防伪标签的防伪特征以及识别的方法是防伪标签的主要结构，食品包装上往往会张贴变色防伪标签，以便于消费者及工作人员对食品真伪进行识别。An anti-counterfeiting label is a mark that can be pasted, printed, or transferred on the surface of an object and has an anti-counterfeiting function. The anti-counterfeiting features and identification methods of the anti-counterfeiting label are the main structure of the anti-counterfeiting label. Color-changing anti-counterfeiting labels are often posted on food packaging to facilitate consumers and staff to identify the authenticity of the food.
如实用新型：“一种光学变色防伪标签”，公告号为：“CN213458103U”，该专利通过在成像层上表面镀制光变层，根据光变层多层复合膜光学干涉原理，可实现从不同角度观测成像层时，显现不同颜色的防伪图案，提高防伪标签的防伪效果，然而该专利在实施过程中，PET基材内部并未设置弹性结构，使得PET基材在受到挤压时，其内部的光变层容易受力变形，容易造成防伪标签损坏，因此，本实用提供一种食品变色防伪标签用于解决上述问题。For example, the utility model: "An optically color-changing anti-counterfeiting label", with the announcement number: "CN213458103U", this patent plates an optically variable layer on the upper surface of the imaging layer. According to the optical interference principle of the optically variable layer multi-layer composite film, when the imaging layer is observed from different angles, anti-counterfeiting patterns of different colors can be displayed, thereby improving the anti-counterfeiting effect of the anti-counterfeiting label. However, during the implementation of this patent, no elastic structure is provided inside the PET substrate, so that when the PET substrate is squeezed, the optically variable layer inside it is easily deformed by force, which can easily cause damage to the anti-counterfeiting label. Therefore, this utility model provides a food color-changing anti-counterfeiting label to solve the above problem.

进一步的，密封底片2的底部安装有防护贴片1，可通过防护贴片1遮挡住粘合通口6，避免液体和灰尘通过粘合通口6进入密封底片2内部。Furthermore, a protective patch 1 is installed at the bottom of the sealing bottom film 2 , and the protective patch 1 can shield the bonding opening 6 to prevent liquid and dust from entering the inside of the sealing bottom film 2 through the bonding opening 6 .
进一步的，防护贴片1的一端安装有防滑撕条13，且防滑撕条13的外侧设置有防滑纹，便于将防护贴片1从密封底片2底部撕下。Furthermore, an anti-skid tear strip 13 is installed at one end of the protective patch 1, and the outer side of the anti-skid tear strip 13 is provided with anti-skid grooves, so as to facilitate tearing the protective patch 1 off from the bottom of the sealing bottom film 2.
工作原理：Working principle:
使用时，可先通过防滑撕条13将防护贴片1从密封底片2下方撕下，然后将密封底片2放置于指定位置处；When in use, the protective patch 1 can be torn off from under the sealing bottom film 2 through the anti-slip tear strip 13, and then the sealing bottom film 2 can be placed at a designated position;
工作人员可向下按压变色防伪标签PET基材3，使得密封底片2受力并挤压切口12位置处，并通过折痕部14使密封底片2折叠，即可将黏胶层7从粘合通口6内部推出，可使黏胶层7直接黏贴在食品包装袋上；The staff can press down the color-changing anti-counterfeiting label PET substrate 3, so that the sealing bottom film 2 is stressed and squeezes the position of the cutout 12, and folds the sealing bottom film 2 through the crease 14, so that the adhesive layer 7 can be pushed out from the inside of the bonding opening 6, so that the adhesive layer 7 can be directly adhered to the food packaging bag;
使用过程中，若变色防伪标签PET基材3受到外界挤压力时，弹性橡胶圈5受力形变，并使第一弹性橡胶片15和第二弹性橡胶片16受力形变，通过弹性橡胶圈5可缓冲挤压力，避免变色防伪涂层9直接受力变形，且在挤压结束后，弹性橡胶圈5、第一弹性橡胶片15和第二弹性橡胶片16的弹性作用可帮助变色防伪标签PET基材3复原，避免变色防伪标签PET基材3受力变形。During use, if the color-changing anti-counterfeiting label PET substrate 3 is subjected to external squeezing force, the elastic rubber ring 5 is deformed under the force, and the first elastic rubber sheet 15 and the second elastic rubber sheet 16 are deformed under the force. The elastic rubber ring 5 can buffer the squeezing force to prevent the color-changing anti-counterfeiting coating 9 from being directly deformed by the force. After the squeezing is completed, the elastic effect of the elastic rubber ring 5, the first elastic rubber sheet 15 and the second elastic rubber sheet 16 can help the color-changing anti-counterfeiting label PET substrate 3 to recover to prevent the color-changing anti-counterfeiting label PET substrate 3 from being deformed by the force.
