ANTI-LEAKAGE PIECE STRUCTURE FOR REFILL POLYVINYL RESIN CONTAINER

摘要

The present invention relates to a structure of the leak-proof piece which is integrally installed to prevent the contents contained in the refilled vinyl container from leaking through the discharge port during transportation or storage, and the present invention is a discharge port (2) to achieve this The leakage preventing piece 10 is integrally formed to prevent leakage of the contents in the container to the outside before opening, but the leakage preventing piece 10 is located at the upper side of the outlet to prevent the leakage of contents requiring less airtightness. The separation surface 14 is formed and opened by the connecting piece 12 connected to the upper peripheral surface of the opening end portion 2b, and the gripping protrusion for having a pressing force according to the gripping to the outer circumferential side of the leak-proof piece 10. The holding part 16 provided with 18 is formed. In addition, the leakage preventing piece 100 is separated from the connecting piece 12 which is located on the inner circumferential surface of the outlet and connected around the edge closest to the inner circumferential surface of the outlet 2 in order to prevent leakage of the contents requiring much airtightness. (14) is formed to be opened, the gripping portion 16 having a gripping protrusion 18 to have a pressing force according to the gripping to the central portion of the leak-proof piece 100 is a certain height to the outside of the outlet (2) By being exposed as much as it is possible to easily separate the leak-proof piece.
