<p>A slotted rear-mounted screw cap, comprising a screw cap (1) mounted with an elastic arched part (2) on the back of the screw cap (1); the arched part (2) is provided with a slotting (21) thereon, and located on both ends or a single end of the back of the screw cap (1); the slotting (21) is located at any position on the surface of the arched part (2); the arched part (2) is made of resin material, metal spring piece or rubber; and the resin material is nylon resin. The present invention replaces an original steel ball with a flexible arched part disposed on a screw cap, has a simple manufacturing process, and increases production efficiency. When the screw cap is in use, squeezing force applied on the arched part is released from the slotting, such that the arched part serves as a flexible support; and when the screw cap is not in use, the arched part immediately restores to the original state for the next use.</p> |
