Bottle Cap Torque Tester

Bottle Cap Torque Tester
A bottle cap torque tester (also known as a torque meter or bottle cap torque apparatus) is primarily used to measure the torque value of bottle caps on bottled products such as beverage bottles, mineral water bottles, and baby bottles during the locking and unlocking process.

Bottle cap torque testers are crucial for ensuring the sealing, quality, and consumer experience of packaged products, and are widely used in quality control processes in the food, pharmaceutical, and cosmetic industries.

I. Main Testing Applications of Torque Testers

Bottled Containers: Suitable for testing the locking and unlocking torque value of bottle caps on bottled food and pharmaceutical products (threaded connections). Examples include beverage bottles, mineral water bottles, pharmaceutical glass bottles, and liquor bottles.

Tube Packaging Products: Suitable for testing the locking and unlocking torque value of bottle caps on tube-packaged food, pharmaceutical, and cosmetic products, such as eye drop bottles, hand cream bottles, and shoe polish (threaded connections).

II. Test Principle of Bottle Cap Torque Meter

The bottle body is fixed in the lower clamping device, and the bottle cap is clamped by the upper clamping device. The bottle cap is rotated at the user-set rotation speed (or manually). The torque sensor connected to the clamping device reads the real-time torque value, thereby measuring the opening or locking force of the bottle cap.
