[0033] According to the above structural characteristics, such as Fig.14 As shown, the bottom cover opening of the outer cover of the squeeze bottle can also be buckled with the outer diameter of the bottle body through the buckle ribs of the inner diameter of the cover opening, and the bottle mouth of the top opening of the bottle body is combined with the ring opening sleeve at the bottom of the large ring for sealing connection, and the large elastic sleeve is buckled with the upper cavity groove at the top of the large ring through the inner plug and then fixed in a limited position.

[0034] The assembly instructions of the squeeze bottle are as follows: the outer cover is assembled, the gasket groove on the top of the outer cover is bonded with the adhesive backing of the gasket, and the limiting ribs of the outer cover are fixedly matched with the bottom cover opening of the inner cover to complete the assembly. The nozzle is assembled, the upper center hole of the inner plug is fixedly matched with the small elastic sleeve, the middle plane of the small elastic sleeve is sealed and flush with the middle plane inside the upper center hole of the inner plug, and the outer diameter of the inner plug is fixedly matched with the inner diameter buckle position of the nozzle orifice; the upper cavity groove of the large circle is fixedly matched with the large elastic sleeve, and the nozzle is assembled; the outer diameter of the nozzle orifice is fixedly matched with the notch at the upper cavity groove of the large circle, that is, the sealing rib at the inner diameter of the nozzle orifice is interference-sealed with the sealing surface of the notch at the upper cavity groove of the large circle, the middle plane of the large elastic sleeve is sealed and flush with the upper center hole at the upper cavity groove of the inner plug, and finally the buckle rib at the cover opening at the bottom of the outer cover of the outer cover assembly is inserted into the outer diameter of the large circle to complete the assembly; at this time, the gasket on the top of the outer cover is interference-sealed with the spray hole 401 of the nozzle, the nozzle hole of the inner cover is gap-matched with the conical concave surface on the side of the nozzle, and is abutted against the anti-side bending ribs on both sides of the inner diameter of the nozzle hole of the inner cover to prevent the outer cover from being easily broken and separated. The finished product has the external thread at the raised bottle mouth in the middle of the top of the bottle body and the internal thread at the large circle middle sleeve that is raised downward in the middle of the bottom of the large circle through thread cooperation, the outer diameter limit block of the bottom cover of the inner cover interferes with the limiting ribs at the inner wall of the outer cover and is buckled to limit the position, the inner wall of the bottle mouth of the bottle body and the outer diameter of the large circle inner sleeve of the large circle are interfered and sealed to complete the assembly.

[0035] The working principle of the squeeze bottle is as follows: the inner plug of the squeeze bottle is equipped with two elastic sleeves, which have sealing and elastic functions. In a static state without external force, the elastic sleeves play an isolating and sealing role; when the nozzle is facing downward to squeeze the bottle body, the small elastic sleeve opens and separates from the inner plug under the action of force, and the contents go out from this gap; when the extrusion is completed (no force), the large elastic sleeve opens and separates from the inner plug under the action of air pressure (force), and air enters from this gap, and the bottle body returns to its original state, that is, it is reused.

[0036] In summary, the structure of the squeeze bottle is a two-way valve structure, which isolates the contents from the external air pressure, and the liquid is discharged only when the bottle body is squeezed under force, thereby improving the quality of use. The two-way valve head of the cosmetic container composed of the large ring, large elastic sleeve, inner plug, small elastic sleeve, and nozzle can also be used in other cosmetic containers to prevent the corresponding cosmetic container from uncontrollably discharging liquid under the action of gravity when the spray hole is facing downward during use.
