Plastics Company TOP The TEN Caps The TEN cap is a plastic cap for use in PET bottles, and it has an excellent tamper evidence function that shows if the cap has been tampered with. It has a band and packing structure developed originally by Nihon Yamamura Glass. When the process of opening the bottle starts, the mechanical band is cut and outside air enters the bottle. In fact, the outside air enters the bottle after the mechanical band breaks off completely. This band and packing structure make it possible to verify that the bottle has been opened, so bottle tampering can be immediately discovered, which has proven to be very effective for preventing tampering in stores. The packing uses polyethylene, which does not have any artificial coloring or lubricant added to it and does not affect the smell or taste of the contents. The packing is also recyclable. Stable Tampering Evidence Indicator Currently caps for 28 diameter beverages used domestically have a tampering evidence indicator that works by the cutting of a bridge. A special feature of the TEN Cap is to prevent tampering by always breaking the bridge and starting a leak when the cap is opened. The TEN-PH5RT CAP consists of two parts such as a shell and packing, which we originally designed and developed. The packing has an inner ring, which forms a stable sealing by direct contacting to the inside and top of the bottle mouth. When the process of opening the bottle starts, the packing is fixed to the bottle mouth, and then lifted up by a screw on the top of the shell. This mechanism causes a leak to begin after the bridge-break, when the LB angle is positive. * The LB angle is L (the leak angle) minus B (the bridge-break angle). When it is greater than zero, then protection against tampering is ensured. The packing that touches the liquid has an additive free polyethylene, so it has no harmful effect on the flavor. The flap structure uses a design that we originally developed, which makes possible a stable bridge-break when the bottle is opened. The design also makes it easy for capping and is flexibly applicable to capping any bottle when the bottle is capped. Nihon Yamamura Glass has licensed the cap band to more than 30 companies in 18 countries, and has licensed the cap itself to Chinese, Taiwanese, and Korean companies.
