Technical Field
[0001] The present application relates to the technical field of plastic barrels, and in particular to a double-sealed plastic barrel cover and a plastic barrel. Background Art
[0002] The main materials of plastic barrels are usually high-density polyethylene, polypropylene or polyvinyl chloride. They are lightweight, corrosion-resistant, impact-resistant and highly plastic, and are widely used in chemical, food, pharmaceutical, agricultural and other industries. The structural design of plastic barrels is diverse, with common ones being round, square and rectangular, and the capacity ranges from a few liters to hundreds of liters, which can meet different usage requirements. Plastic barrel covers are usually designed in various forms such as screw caps, press caps and buckle caps. In order to ensure good sealing performance of the plastic barrel cover and prevent leakage and contamination of the contents, double-seal plastic barrel covers are usually used.
[0003] In the related art, plastic barrels are mainly sealed by double-seal plastic barrel covers. When in use, a side sealing ring is arranged on the outer wall of the cover to form a gap. When the barrel cover is placed on the plastic barrel, the side sealing ring is used to stop and close. At the same time, a groove bar and a to-be-torn ring are arranged to form a card groove for clamping and closing the side wall sealing ring of the plastic barrel, thereby achieving a double-layer seal and ensuring the sealing and stability of the barrel cover and the plastic barrel. When opening the barrel cover, it is only necessary to push the tear-off plate to tear the to-be-torn ring from the groove bar position and separate it from the side sealing ring, so that the card groove structure formed by the groove bar can be opened, so that the side sealing ring can be easily separated from the plastic barrel, thereby improving the convenience of the opening operation. However, the to-be-torn ring is generally disposable, which may not be convenient for personnel to reuse the double-seal plastic barrel cover and the plastic barrel.
