The 2015 version of the drug packaging material standard YBB00402003-2015 "Aluminum plastic composite caps for infusion bottles" specifies the detection indicators for the opening force of aluminum-plastic composite caps for infusion bottles; The so-called opening force value refers to the force value at which the plastic cover and aluminum cover separate.

　　Why test the opening force of aluminum-plastic composite caps for infusion bottles？

Repeated manual lifting of aluminum-plastic composite caps by nursing staff can easily cause finger pain and injury. When a large amount of medication is needed in clinical practice, the workload of opening the cap is heavy and tedious, and repeated operations can cause hand pain and fatigue, which can easily lead to accidental injuries due to occupational fatigue.

　　Standard requirements for testing the opening force of aluminum-plastic composite caps for infusion bottles；

【 Opening Force 】 Plastic removal force: Take an appropriate amount of this product and conduct a test on a stretching device, as shown in Figure 3, with a test speed of 100mm/min ± 100mm/min. It should comply with the provisions in Table 1.

　　Aluminum plastic composite cap opening force detection equipment for infusion bottles；

The YYB-03 aluminum-plastic combination cap opening force tester for infusion bottles is used to determine the opening performance of aluminum-plastic combination caps for various drug packaging. This instrument has the characteristics of simple structure and easy operation. Its main technical performance and indicators comply with the provisions of YBB00402003-2015 "Aluminum plastic composite caps for infusion bottles" standard, and can be used by relevant production and research departments.

Aluminum plastic composite cap opening force tester for infusion bottles

　　Principle of testing the opening force of aluminum-plastic composite caps for infusion bottlesClamp the sample between the two clamping heads of the film tensile strength tester fixture, and make relative movements between the two clamping heads. Through the force sensor located on the moving clamping head and the displacement sensor built into the machine, collect the changes in force and displacement during the test process, and calculate the performance indicators such as tensile strength, tearing strength, and deformation rate of the sample.

　Experimental method for opening force of aluminum-plastic composite caps for infusion bottles

(1) Randomly select 5 infusion bottles from the test sample and cover them with aluminum-plastic composite caps.

(2) Take one of the samples, fix the bottle cap in the lower fixture, and hang the pull tab hook in the upper fixture.

(3) In the control software of the device, set parameter information such as sample name, test speed, and test frequency. Click on the test option to start the test. The upper fixture moves upward, and the device software displays the force value change curve during the pulling process. After the test is completed, the test value is displayed.

(4) Clamp and test the other 4 samples separately, and record the actual test values of each sample in sequence.

　　Aluminum plastic composite cap opening force tester YYB-03 for infusion bottles maintenance and upkeep：

1. After the experiment is completed, wipe the surface of the instrument clean and apply engine oil to the surface and sides of the base.

2. The screw should be kept clean regularly.
