Abstract:
Provided is a screw-top non-cover-opening assembly, comprising a base (1); the base (100) is open at both ends and is hollow; the opening of the base (100) is connected to an upper cover (200); the upper cover (200) is provided with a liquid outlet window (201); the upper cover (200) is directly or indirectly connected to a movable plug (300) which can extend movably into the inner cavity of the base (100); a sealing member (101) which blocks the openings at both ends of the base (100) is disposed in the base (100) and under the movable plug (300); the side wall of the base (100) is also provided with a liquid outlet sleeve (102) which is used for communicating the inner cavity of the base (100) with the outside and which can be used in conjunction with the liquid outlet window (201); the upper cover (200) being connected to the opening of the base (100) causes the base (100) to have a multi-stage sealing structure to ensure that a substance in a container does not deteriorate for a long time; furthermore, the liquid outlet sleeve (102) and the liquid outlet window (201) can be used together to ensure that the upper cover (200) can, without being separated from the base (100), be used by a user for pouring out the substance in the internal cavity of the container; therefore the invention has the characteristics of good sealing performance, smooth liquid discharge, easy operation, and convenience and hygiene, and the upper cover is not prone to be lost, such that the invention has the feature of being environmentally friendly.
