Pet container cap with simultaneously separable end ring

A PET container cap with a simultaneously separable end ring, which provides tight blocking for preservation of contents in a state of being provided on and coupled to an injection part and provides a sealing function enabling awareness of openness, the cap comprising:

• a cap body provided on and coupled to the injection part to provide tight blocking for preservation of the contents;
• and
• an end ring integrally formed on a lower side of the cap body, restricted by an annular protrusion protruding from a lower side of an outer circumference of the injection part, exhibiting a sealing function enabling grasping of openness of the cap body, and causing transformation in a separation process of the cap body by a user, so the end ring is separated together with the cap body from the injection part,
• wherein the end ring comprises:
• an interference protrusion restricted by the annular protrusion when the cap body is coupled to the injection part;
• a plurality of transformation parts transformed to flare out, thus allowing the interference protrusion to pass over the annular protrusion when the cap body is separated from the injection part, due to a “”-shaped cut part extending horizontally and vertically from a boundary of the cap body;
• and
• a sealing projection protruding from an upper end of each of the transformation parts to be integrally connected to a lower end of the cap body, fractured in the separation process of the cap body, and enabling the openness of the cap body to be identified depending on a fractured state.

• a plurality of interference protrusions formed on an inner circumference of a boundary between the cap body and the end ring to protrude at regular intervals, connecting the cap body and the end ring, restricted by the annular protrusion when the cap body is coupled to the injection part, and changed in shape to pass over the annular protrusion in the process of separating the cap body;
• and
• a sealing projection formed on the inner circumference of the boundary, connecting a lower end of the cap body and an upper end of the end ring, fractured in the separation process of the cap body, and enabling the openness of the cap body to be identified depending on the fractured state.
