After the unsealed lead bag is filled with glue and used, the plastic diversion nozzle is removed, and the inner layer is equipped with rubber, and the surface layer is equipped with multi-layer plastic films. The cover will seal the outlet, and store it with the seal facing down. If you want to use it again, unscrew the cover, and then there will be a piece of plastic film close to the glue outlet, and then pierce it with a sharp object and install the plastic diversion nozzle. use. Because the inner layer of the cover has rubber with elasticity, and the outer layer has multiple layers of film, each use will consume a layer of film, but the elastic film of rubber can be used to seal the glue outlet tightly, and the glue can be turned upside down. Leakage and volatilization will not occur.
