the first one-way valve is arranged at the liquid outlet and can move up and down so as to open or close the liquid outlet, and the first one-way valve only allows the substances in the channel to flow out of the liquid outlet;

the valve core is arranged in the opening, can move downwards relative to the opening under the action of external force, and is in sealing connection with the inner peripheral wall of the opening;

the button is positioned above the opening and is connected with the valve core through the valve rod;

and the elastic element acts on the valve core to ensure that the valve core always keeps the trend of moving upwards.

In order to further improve the sealing property in the cavity and ensure that the cream is not polluted, a second one-way valve is further arranged at the liquid inlet and can move up and down relative to the liquid inlet so as to shield or open the liquid inlet, and the second one-way valve only allows substances in the cavity to flow into the channel.

In order to prevent the frost from being contaminated by the elastic member when flowing into the passage, the elastic member is disposed outside the passage, and the elastic member acts on the push button to keep the push button always moving upward.

In order to limit the upward movement stroke of the valve core and prevent the valve core from moving out of the opening under the action of the elastic piece, a flange which can be abutted against the upper end of the valve core is formed on the inner wall of the opening. When the valve core is abutted against the flange, the valve core cannot move upwards continuously.

In order to facilitate the arrangement of the pump seat and the positioning of the pump seat, the bottle body is provided with a step for the pump seat to be placed on, the step is the top wall of the bottle body or is formed on the inner peripheral wall of the bottle body and is arranged close to the top of the bottle body, the top of the bottle body is in threaded connection with a cover body, and the cover body enables the outer peripheral edge of the pump seat to be pressed on the step so as to position the pump seat; the cover body is provided with a liquid outlet hole communicated with the liquid outlet, and the button can be inserted on the cover body in a vertically moving mode.

In order to hide the liquid outlet hole and prevent the liquid outlet hole from being exposed and polluted, the cover is connected with a cover body through a horizontally arranged pivot, and the liquid outlet hole and the button are covered by the cover in a state that the cover is covered on the cover body. When the cream needs to be used, the cover is opened, and then the button is pressed.

In order to improve the aesthetic property of the cream bottle, a decorative cover is sleeved on the cover.

The channel can have multiple structural style, simple structure, the channel includes horizontal section and upper and lower both ends open first vertical section, second vertical section, third vertical section, first vertical section and second vertical section interval set up, the lower extreme of first vertical section and second vertical section all communicates with horizontal section, and the upper end of first vertical section is the liquid outlet, and the upper end of second vertical section is the opening, case activity cartridge is in the second vertical section, the upper end and the horizontal section of third vertical section intercommunication, the lower extreme of third vertical section is linked together with the cavity, the liquid inlet is arranged in the third vertical section, and the second check valve is arranged in the third vertical section. Therefore, a liquid outlet, an opening and a liquid inlet do not need to be additionally arranged, and the manufacturing is simple.

In order to ensure that the cavity is in a vacuum state, the space in the cavity is filled with the cream all the time, one mode is as follows: the bottle is internally provided with a piston which can move up and down relative to the bottle, the outer peripheral wall of the piston is in sealing fit with the inner peripheral wall of the bottle, and the piston and the inside of the bottle jointly enclose into the cavity. After the cream in the cavity is used, the piston can move upwards under the action of the atmospheric pressure, so that the space of the cavity is reduced, and the residual cream is filled in the cavity all the time.

In order to ensure that the cavity is in a vacuum state, and the space in the cavity is filled with the cream all the time, the other mode is as follows: the bottle body is internally provided with a deformable vacuum flexible bag, the inner space of the vacuum flexible bag is the cavity, and the top opening of the vacuum flexible bag is communicated with the liquid inlet. After the cream in the cavity is used, the vacuum flexible bag deforms under the action of the atmospheric pressure, so that the space of the cavity is reduced, and the residual cream is filled in the cavity all the time.

Compared with the prior art, the invention has the advantages that: according to the invention, the opening and the liquid outlet are arranged at intervals, the button capable of moving up and down is arranged at the opening, when the button is pressed, air in the channel is extruded, so that the first one-way valve is opened, and the button is continuously pressed, cream in the vacuum chamber can enter the channel and flow out of the liquid outlet, thus contact between the cream in the cavity and the air is avoided, and the button and the liquid outlet are arranged at intervals, so that the liquid outlet is not blocked when the button is pressed, and the use is more convenient; in addition, the button and the first one-way valve work independently, and the phenomenon that the button or the first one-way valve is blocked due to interference of the other party does not exist.
