瓶口螺纹标准

瓶口螺纹标准 Cap and Neck Finishes Screw thread cap sizes are generally expressed as two numbers。 The first number refers to the cap diameter (in millimeters） and the correspondin g Glass Packaging Institute (GPI)/Society of the Plastics Industry (SPI) finish diameter. The second number refers to the height and thread configuration of the closure or finish。 Below is a selection of commonly used caps and finishes. S=S=Threa d Start H=H=Finis h Height T=T=Majo r Diamete r E=E=Mino r Diamete r I=I=Hole Diamete r T T — Outside diameter of the continuous thread E E — Outside diameter of the finish shaft excluding thread I I — The inside diameter of the finish at the smallest possible point S S — The distance between the top of the finish to the top of the thread L L - The distance between the top of the finish to the top of the transfer bead(optional) H H — Height from the top of the finish to the bottom where it intersects with the shoulder WW — The thickness of the transfer bead （optional） Standard Plastic Finishes Most Commonly Used。。。 The diameter of ClosuresStandard Neck Finishes ( 1 turn of thread) （1 圈螺牙）（ 1.5 turn of thread) （1。5 圈螺牙） (Short 2 turns thread) （低位 2 圈螺牙）（高位 2 圈螺牙）（Tall 2 turns thread) Plastic Thread s。。. Plastic thread finishes typically have a standard ”M” style thread ，shown here。An “L“ style can also be used but is not as common. The root dimension will vary depending on the threads per inch of the finish. Special thread s can also be designed.
