[0002] Generally, bottles used for packaging beverages, foods, medicines, etc. are provided with flip-top bottle caps, which have an upper cover and a lower cover that can be opened and closed, and the lower cover is connected to the bottle mouth of the bottle. A tear strip for the user to tear and pull open is provided between the upper cover and the lower cover. When the tear strip is torn and pulled open, the user can flip the upper cover relative to the lower cover, thereby realizing the function of opening and closing the bottle cap. For the specific structure, reference can be made to the patent product structure of patent number CN201520578499.4, which is named a new type of anti-theft bottle cap. However, when using this bottle cap structure, it must be ensured that the tear strip is firmly connected before it is pulled open and will not fall off easily. At the same time, when the user pulls the tear strip, the tear strip can be easily pulled open. Therefore, the stress performance of the tear strip when it is torn open is very important for the performance of the corresponding product, and it is particularly important to test the stress of the tear strip during the product production process.
