Abstract
The utility model relates to the technical field of packaging bottles, and discloses a self-sealing valve element liquid outlet bottle which comprises a bottle body, a shoulder sleeve and a cover, an inner plug is installed in an inner cavity of the shoulder sleeve, a liquid outlet channel is arranged in the shoulder sleeve, a liquid outlet assembly is arranged in an inner cavity of the liquid outlet channel, and the liquid outlet assembly comprises a plug and a spring. An annular part is arranged on the outer side of the surface of the plug and makes contact with the inner wall of the liquid outlet channel. The plug is supported through the spring, the annular portion and the conical portion on the plug abut against the inner wall of the liquid outlet channel to form the first sealing point, liquid outlet can be achieved by pressing the plug in the using process, sealing is achieved through elasticity of the spring in the sealing process, an inner cavity of the liquid outlet channel is plugged again, using is convenient, and after the cover is installed, the sealing effect is good. The inner wall of the fixed sealing sleeve is in contact with and attached to the outer side of the top end of the shoulder sleeve to form a second sealing point, then second-layer sealing is achieved, the second sealing point is used in cooperation with the first sealing point, double sealing is achieved, and liquid leakage can be effectively avoided.
