瓶口螺纹标准Cap and Neck FinishesScrew thread cap sizes are generally expressed as two numbers. The first number refers to the cap diameter (in millimeters) and the corresponding 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=Thread StartH=Finish HeightT=Major DiameterE=Minor DiameterI=Hole DiameterT - Outside diameter of the continuous threadE - Outside diameter of the finish shaft excluding threadI - The inside diameter of the finish at the smallest possible pointS - The distance between the top of the finish to the top of the threadL - The distance between the top of the finish to the top of the transfer bead (optional)H - Height from the top of the finish to the bottom where it intersects with the shoulderW - 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）（高位 2 圈螺牙） (Tall 2 turns thread)(Short 2 turns thread) （低位 2 圈螺牙）Plastic Thread Forms.Plastic thread form finishes typically have a standard “M“ style thread form, 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 forms can also be designed.Recommended Application Torque (Inch / Pounds)Cap Size 盖子尺寸盖子尺寸Glass 玻璃玻璃Plastic 塑料瓶塑料瓶208-1210-122410-1512-152811-1713-173313-2016-203815-2319-234317-2621-264518-2823-284819-2924-295321-3227-325823-3529-356325-3831-387028-4235-428926-5344-5310040-6048-6011045-6555-6512048-7260-72瓶口螺纹详细图纸MMTE400H410H415HSITHDSPERINCHMAXMINMAXMINMAXMINMAXMINMAXMINMAXMINMIN13.514.502.454.442.467.437.052.022.2181215.581.569.521.509.572.542.052.022.2581218.704.688.620.604.386.356.538.508.632.602.052.022.325820.783.767.699.683.386.356.569.539.757.727.052.022.404822.862.846.778.762.386.356.600.570.852.822.052.022.483824.940.924.856.840.415.385.661.631.972.942.061.031.5168281.0881.068.994.974.415.385.723.6931.0971.067.061.031.6146301.1271.1071.0331.013.418.388.061.031.6536331.2651.2411.1711.147.418.388.061.031.7916351.3641.3401.2701.246.418.388.061.031.8756381.4761.4521.3821.358.418.388.061.031.9876401.5801.5501.4861.465.418.388.061.0311.0916431.6541.6241.5601.530.418.388.061.0311.1656451.7401.7101.6461.616.418.388.061.0311.2516481.8701.8401.7761.746.418.388.061.0311.3816511.9681.9331.8741.839.423.393.061.0311.4796532.0672.0321.9731.938.423.393.061.0311.5786582.2242.1892.1302.095.423.393.061.0311.7356602.3422.3072.2482.213.423.393.061.0311.8536632.4612.4262.3672.332.423.393.061.0311.9726662.5791.1072.4852.450.423.393.061.0312.0906702.7362.7012.6422.607.423.393.061.0312.2476752.9132.8782.8192.784.423.393.061.0312.4246773.0353.0002.9142.906.502.472.075.0452.5466833.2683.2333.1483.113.502.472.075.0452.7535893.5113.4763.3913.356.550.520.075.0452.91851003.9373.9023.8173.782.612.582.075.0453.34451104.3314.2964.2114.176.612.582.075.0453.73751204.7244.6894.6044.569.700.670.075.0454.1315瓶口形状大全。
