[0002] Cosmetics, such as lotions, are commonly used beauty and skin care products in daily life. For this reason, manufacturers have launched a variety of cosmetic storage products to facilitate people's use and storage within a reasonable time.

[0003] Therefore, providing products that enable people to use cosmetics more conveniently and store them more safely is a goal and task that manufacturers need to research and develop and improve in the long term. Utility Model Content

[0004] The purpose of the utility model is to provide a press-to-extrude type lotion storage bottle, which has a good manual liquid discharging device and a liquid storage structure, is convenient for users to use and can safely store lotion.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A press-to-extract lotion storage bottle comprises a liquid storage bottle and a manual liquid discharging device. The liquid storage bottle is provided with a piston that cooperates with the inner side surface of the liquid storage bottle, the bottom of the piston is provided with a bracket, an air pressure space is provided between the bottom of the piston and the inner bottom surface of the liquid storage bottle, the bracket is provided in the air pressure space, and the inner bottom surface of the liquid storage bottle is provided with an air vent that cooperates with the air pressure space; the manual liquid discharging device comprises a top cover, a connecting seat, a button, an inner plug, and two one-way valves. The top cover is sealed with the top of the liquid storage bottle and forms a liquid storage space between the piston. The middle of the top cover is provided with a There is a liquid outlet channel isolated from the edge part, a top cover valve hole is provided in the middle of the liquid outlet channel, the top cover valve hole is provided with a first one-way valve allowing liquid in the liquid storage space to flow to the liquid outlet channel, the connecting seat is tightly attached to the upper part of the top cover and seals the liquid outlet channel, the connecting seat is provided with a button hole and a liquid outlet hole isolated from each other, the button hole and the liquid outlet hole are respectively connected to the liquid outlet channel, the button is made of soft material and is in a cover shape, the button hole is sealed with the button, and the liquid outlet hole is provided with a second one-way valve allowing liquid in the liquid outlet channel to flow to the outside.

[0007] This solution uses a cover-shaped soft button with two one-way valves as a tool for extracting and squeezing out the emulsion. A one-way valve is installed between the liquid outlet channel and the liquid storage space (only allowing the liquid in the liquid storage space to flow into the liquid outlet channel), and a one-way valve is installed between the liquid outlet channel and the outside (only allowing the liquid in the liquid outlet channel to flow out). Before squeezing the button, the pressures among the outside, the liquid outlet channel, and the liquid storage space are balanced. When the button is pressed, the air in the liquid outlet channel is squeezed out, and the one-way valve on the valve hole of the top cover is closed by air pressure, preventing air from entering the liquid storage space. The one-way valve on the liquid outlet hole is opened by air pressure, and the air is discharged from the liquid outlet hole. Out; release the button, and the button returns to its original shape under the action of elasticity. At this time, the air in the liquid outlet channel is partially discharged and the pressure is reduced. The one-way valve on the liquid outlet hole is closed, while the pressure in the liquid storage space remains unchanged. Therefore, the one-way valve on the valve hole on the top cover is opened, and the pressure in the liquid storage space and the liquid outlet channel is balanced but still lower than the external air pressure. The air pressure space at the bottom of the piston is connected to the outside through the air vent to maintain the pressure unchanged. Therefore, the piston is pushed upward until the pressure in the liquid storage space and the liquid outlet channel is the same as that outside. When the piston is pushed upward, the emulsion in the liquid storage space is squeezed into the liquid outlet channel; after pressing the button again, the emulsion in the liquid outlet channel is squeezed out from the liquid outlet hole.

[0008] As a preferred embodiment of the present invention, the liquid storage bottle comprises an outer bottle, an inner bottle, and a bottom cover. The bottom of the outer bottle is connected to the bottom cover, the inner bottle is disposed between the bottom cover and the top cover, the piston is disposed within the inner bottle, the side surface of the piston is in sealing contact with the inner side surface of the inner bottle, an air pressure space is defined between the bottom of the piston and the inner bottom surface of the inner bottle, and the inner bottle and the bottom cover are provided with air holes. The outer bottle and bottom cover of this embodiment protect the inner bottle, preventing the inner bottle storing the emulsion from directly rupturing in the event of an impact, and forming an air layer outside the inner bottle to reduce the degree to which the emulsion stored in the inner bottle is affected by the ambient temperature.

[0009] As a preferred embodiment of the present invention, the top of the outer bottle is provided with an inner step and an outer step, the outer edge of the top cover is provided with a right-angle buckle that abuts against the inner side of the inner step, the outer side of the inner step abuts against the inner side of the outer edge of the connecting seat, and the outer side of the connecting seat is provided with a middle section, the inner side of the outer edge of the middle section abuts against the outer step. The arrangement of the outer bottle, top cover, connecting seat, and middle section of this embodiment allows for interlocking and improved sealing of the liquid outlet passage.

[0010] As a preferred embodiment of the present invention, the edge of the button hole on the top side of the connecting base is provided with a downwardly-facing annular groove, the outer edge of the annular groove opening is provided with a buckle edge that protrudes into the annular groove, the bottom opening edge of the button is located within the annular groove, and a sealing ring is further provided within the annular groove, the sealing ring being secured to the outside of the button by the buckle edge. This embodiment provides a good seal between the button and the button hole through the sealing ring.

[0011] As a preferred embodiment of the present invention, the top side of the connecting seat is provided with an upwardly protruding liquid outlet platform, the liquid outlet platform being hollow inside, the liquid outlet hole being provided on the liquid outlet platform, the bottom side of the connecting seat being provided with a downwardly extending liquid outlet pipe that cooperates with the liquid outlet hole, an inner plug being provided between the outer side of the liquid outlet pipe and the inner side of the liquid outlet platform, and a one-way valve seat being provided within the liquid outlet pipe. The inner plug of this embodiment reduces the liquid outlet area and improves the sealing between the liquid outlet channel and the liquid outlet pipe. A hollow tube is provided in the middle of the one-way valve seat as the liquid outlet, which is connected to the liquid outlet pipe via ribs. The bottom of the one-way valve extends into the liquid outlet and covers the entire liquid outlet hole.

[0012] As a preferred solution of the present invention, the outer side of the connecting seat is provided with an annular middle section and an outer cover, the outer side of the middle section is provided with an outer cover step, and the bottom edge of the outer cover is provided on the outer cover step. The outer cover of this solution can be used to protect the connecting seat.
