Abstract: Bottle and barrel packaging is a common form of packaging for wine, and the opening torque of the bottle cap is one of the important properties of bottled or bottled wine, which is related to the convenience of opening and the overall sealing of the package. Opening torque test paper wine bottle glass bottles for example, describes a method for detecting a cap opening torque, and the scope of application, etc. parameter information, Labthink torque meter NJY-20 were involved in the test The introduction helps the company to understand the test process of opening torque and related detection principles, so as to provide reference for the opening performance of the company's monitoring related products.

1 , meaning

    "Liquor" can be divided into edible wine, medical alcohol and industrial alcohol according to the use, and the edible wine packaging is generally packaged in glass bottles or plastic drums. The opening torque value of the bottle in the transportation and storage links has an important impact on the quality of the container packaging and the final consumption. Therefore, it has become one of the process parameters for the offline or online key control of the wine production enterprise.

The cap opening torque is the amount of torque required to unscrew the cap and is a physical quantity that characterizes the ease with which the cap is opened. If the opening torque value of the bottle cap is low, it will bring certain risks to the sealing performance of the package, and it is prone to problems such as leakage of liquid and alcohol evaporation, thereby affecting the taste and total volume of the wine; and the opening torque value of the cap is over Larger, it will make the opening of the package more difficult, and it needs to be opened by other external forces, which not only increases the difficulty of the consumer, but also may cause scratches and other accidents due to opening the package. Therefore, it is important to control the opening torque of the appropriate cap.

2 , standard situation

China's bottle cap torque testing standard GB/T 17876-2010 "packaging container Plastic anti-theft caps, BB/T 0025-2004 " 30/25mm plastic anti-theft caps" and BB/T 0034-2006 "aluminum anti-counterfeit caps", etc., this article refers to the standard GB/T 17876-2010 for sample testing .

3 , test samples

5 , the test process

(1) Turn on the torque meter power switch and set the parameter information such as test mode and statistics.

(2) Place the specimen on the clamp and clamp it.

(3) Click the test option and unscrew the cap by hand. The instrument automatically tests the maximum torque value of the sample during the opening of the cap and shows the opening torque of the specimen.

6 , test results

Article 5 samples were tested, five samples opening torque were 3.675 N · m, 3.276 N · m, 2.957 N · m, 3.146 N · m, 3.382 N · m.
