If present, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in the present application are only for illustrative purposes and do not represent the only implementation.

[0052] Referring to Figures 1 to 13 As shown, the present application provides a dropper container, which comprises a container body 1000 and a dropper body 2000, the inside of the container body 1000 has a container chamber, the container body 1000 is provided with a container bottle shoulder 1100, the bottle mouth of the container bottle shoulder 1100 communicates with the container chamber. Wherein, the container body 1000 can be connected with the container bottle shoulder 1100 by ultrasonic welding sealing, and the container body 1000 can also be provided with a detachable container bottom cover 1300. The container chamber can be configured to store essential oil liquid.

[0053] The dropper body 2000 comprises a dropper cover body 2100, a deformation capsule body 2200 and a liquid guide tube body 2300, the inside of the dropper cover body 2100 has a cover body chamber, the deformation capsule body 2200 is assembled in the cover body chamber of the dropper cover body 2100, the deformation capsule body 2200 can be made of rubber or other materials, the deformation capsule body 2200 has a capsule body inner cavity, the deformation capsule body 2200 is configured to have an expanded state and a contracted state, so that when the deformation capsule body 2200 is subjected to an external force such as extrusion or pressing, the state of the deformation capsule body 2200 can be changed due to the external force, so that the deformation capsule body 2200 is converted from the expanded state to the contracted state, so that the air in the capsule body inner cavity forms a vacuum negative pressure state.

[0054] The shape-changing capsule 2200 has a liquid guide end hole 2201 communicating with the capsule inner cavity, and the inner channel of the liquid guide tube 2300 communicates with the capsule inner cavity of the shape-changing capsule 2200 through the liquid guide end hole 2201, so that the shape-changing capsule 2200 is forced to change from the expanded state to the contracted state, so that when the air in the capsule inner cavity forms a vacuum negative pressure state, the vacuum negative pressure can suck liquid through the inner channel of the liquid guide tube 2300, similar to manually squeezing the shape-changing capsule 2200 to suck liquid through the inner channel of the liquid guide tube 2300.

[0055] Different is that the dropper cover 2100 is movably assembled on the container bottle shoulder 1100, so that the dropper cover 2100 can move relative to the container bottle shoulder 1100, for example, the dropper cover 2100 is movably assembled on the container bottle shoulder 1100 by threaded rotation, when the dropper cover 2100 can move relative to the container bottle shoulder 1100, the dropper cover 2100 can drive the shape-changing capsule 2200 and the liquid guide tube 2300 to move synchronously relative to the container main body 1000 and the container bottle shoulder 1100, at this time, based on the synchronous movement relative to the container main body 1000 and the container bottle shoulder 1100, the shape-changing capsule 2200 can be configured to be in direct or indirect force contact with the container main body 1000, for example, when the dropper cover 2100 is closed (e.g., clockwise rotation), the dropper cover 2100 presses the shape-changing capsule 2200 upward, compressing the air in the capsule inner cavity of the shape-changing capsule 2200, at this time the shape-changing capsule 2200 is in the contracted state, when the dropper cover 2100 is separated (e.g., counterclockwise rotation), the compressed part of the shape-changing capsule 2200 returns to its original state.

[0056] The shape-changing capsule 2200 moves synchronously relative to the container main body 1000 and the container bottle shoulder 1100, and the force acting on the shape-changing capsule 2200 relative to the container main body 1000 changes, different force acting on the shape-changing capsule 2200 can cause the shape-changing capsule 2200 to change from the expanded state to the contracted state to different degrees, and the vacuum negative pressure state of the air in the capsule inner cavity also changes synchronously.

[0057] In one of the embodiments, when the dropper cover 2100 is movably assembled on the container neck 1100, the dropper cover 2100 is fixedly moved relative to the container neck 1100 from the beginning of the assembly of the dropper cover 2100 on the container neck 1100 to the end of the assembly of the dropper cover 2100 on the container neck 1100. Therefore, the force generated by the force contact between the deformable capsule 2200 and the container body 1000 is fixed during the entire assembly process. The fixed force eventually causes the deformable capsule 2200 to be in a fixed contracted state, and the vacuum negative pressure formed by the air in the capsule cavity is also fixed.

[0058] Therefore, when the dropper cover 2100 is completely assembled on the container neck 1100, the air in the capsule cavity forms an expected vacuum negative pressure state to suck a fixed amount of liquid. When the dropper cover 2100 is separated from the container neck 1100 again, the force generated by the force contact between the deformable capsule 2200 and the container body 1000 disappears, and the deformable capsule 2200 is converted from the contracted state to the expanded state, and the vacuum negative pressure state in the capsule cavity sucks liquid.

[0059] Since the vacuum negative pressure state of the air in the capsule cavity is fixed, a fixed amount of liquid is automatically sucked every time the deformable capsule 2200 and the container body 1000 are separated (opened), and no additional manual operation is required. The user only needs to operate the process of opening the deformable capsule 2200 relative to the container body 1000 to simultaneously suck the expected amount of liquid, which is very convenient to operate.

[0060] The deformable capsule 2200 can be directly or indirectly in force contact with the container body 1000 in various ways. For example, when the dropper cover 2100 is movably assembled on the container neck 1100, the deformable capsule 2200 is directly pressed against the container body 1000. Alternatively, the length of the liquid guide tube 2300 is greater than or equal to the depth of the container cavity of the container body 1000. When the dropper cover 2100 is movably assembled on the container neck 1100, the liquid guide tube 2300 gradually approaches the bottom inner wall of the container cavity of the container body 1000. Thus, the deformable capsule 2200 is indirectly in force contact with the container body 1000 by the contact between the liquid guide tube 2300 and the bottom inner wall of the container cavity of the container body 1000.

[0061] Moreover, the bottom inner wall of the container chamber of the container body 1000 can also be provided with a liquid collecting groove 1001 for accommodating the bottom of the liquid guide pipe body 2300 when the liquid guide pipe body 2300 is inserted into the container chamber, so that the deformation capsule 2200 is configured to be indirectly contacted with the liquid collecting groove 1001 through the liquid guide pipe body 2300. The deformation capsule 2200 is fixed in the dropper cover body 2100, such as between the first cover body 2110 and the second cover body 2120, and the liquid guide pipe body 2300 is assembled on the deformation capsule 2200 and directly contacted with the liquid and the liquid collecting groove 1001.

[0062] Meanwhile, the bottom inner wall of the container chamber of the container body 1000 can also be provided with an inclined wall surface, so that the height gradually decreases towards the direction of the liquid collecting groove 1001, and the wall surface is inclined downward, so that all the liquid on the bottom inner wall of the container chamber of the container body 1000 can be concentrated to the liquid collecting groove 1001, and the bottom of the liquid guide pipe body 2300 can suck all the liquid when it is inserted into the liquid collecting groove 1001, and the waste of wall surface liquid.

[0063] In one embodiment, at least one locking buckle 2101 is arranged in the cover chamber of the dropper cover body 2100, the end of the locking buckle 2101 is provided with a locking part 2102, and at least one locking slide 1110 is arranged on the container shoulder 1100 of the container body 1000, the locking slide 1110 extends along the circumferential direction of the container shoulder 1100, and the number of extension circles can be one or more, at this time, the locking part 2102 of the locking buckle 2101 can be configured to slide along the locking slide 1110, thereby locking the dropper cover body 2100 and the container body 1000.

[0064] Therefore, when the dropper cover body 2100 and the container body 1000 need to be assembled or separated, the locking part 2102 of the locking buckle 2101 can be slid into or out of the locking slide 1110 by rotating, and in this way, the quick assembly or quick separation between the dropper cover body 2100 and the container body 1000 can be realized, the quick opening and closing between the dropper cover body 2100 and the container body 1000 can be realized, and the user can quickly open or close the dropper cover body 2100 and the container body 1000, and the operation is more convenient.

[0065] In one of the embodiments, the container body 1000 is provided with a container bottle shoulder 1100, which is provided with at least one guide slide 1120, which is in communication with the locking slide 1110, and the locking buckle part 2102 of the locking buckle 2101 is configured to slide along the guide slide 1120 to the locking slide 1110, and at least a part of the surface of the locking buckle part 2102 is configured as an arc surface. Based on the above-mentioned guide slide 1120, the locking buckle part 2102 of the locking buckle 2101 can be quickly introduced into the locking slide 1110, especially when the surface of the locking buckle part 2102 is configured as an arc surface, the arc surface can be quickly introduced into the guide slide 1120 at any angle, thereby being able to slide into the locking slide 1110 more quickly, realizing the quick opening and closing of 360 degrees.

[0066] In one of the embodiments, the dropper body 2000 includes a dropper rubber head 2400, which can be made of a deformation material such as rubber, and the dropper rubber head 2400 is arranged on the dropper cover body 2100, the inside of the dropper rubber head 2400 has a tube head inner cavity, the dropper rubber head 2400 is provided with a tube head cavity opening communicating with the tube head inner cavity, the deformation capsule 2200 has a gas guide end hole 2202 communicating with the capsule inner cavity, and the tube head cavity opening of the dropper rubber head 2400 is in sealed communication with the gas guide end hole 2202 of the deformation capsule 2200. Therefore, the capsule inner cavity of the deformation capsule 2200 and the tube head inner cavity of the dropper rubber head 2400 can jointly form a closed overall inner cavity.

[0067] In one of the embodiments, the dropper cover body 2100 includes a first cover body 2110 and a second cover body 2120, the inside of the first cover body 2110 has a first chamber, the top of the first cover body 2110 is provided with a first through hole penetrating through the first chamber, and the dropper rubber head 2400 is arranged in the first through hole. The inside of the second cover body 2120 has a second chamber, the top of the second cover body 2120 is provided with a second through hole penetrating through the second chamber, and the deformation capsule 2200 is arranged in the second through hole.

[0068] The second cover body 2120 is assembled in the first chamber of the first cover body 2110, and the first cover body 2110 and the second cover body 2120 have a pressing gap 2111, and part of the structure of the deformation capsule 2200 and part of the structure of the dropper rubber head 2400 are sealingly assembled in the pressing gap 2111 between the first cover body 2110 and the second cover body 2120, so that the tube head cavity opening of the dropper rubber head 2400 is in sealed communication with the gas guide end hole 2202 of the deformation capsule 2200.

[0069] For example, the edge of the air guide end hole 2202 of the shape-changing capsule 2200 and the edge of the tube head cavity of the dropper rubber head 2400 are clamped and sealed in the pressing gap 2111 between the first cover 2110 and the second cover 2120, so that the tube head cavity of the dropper rubber head 2400 is in sealed communication with the air guide end hole 2202 of the shape-changing capsule 2200.

[0070] In one embodiment, an inner cover 2130 is arranged in the second cavity of the second cover 2120, and the liquid guide tube 2300 is movably arranged in the inner cover 2130. The inner cover 2130 has at least one limiting portion 2131, such as a limiting portion 2131 arranged at the bottom, top or middle of the inner cover 2130. The limiting portion 2131 of the inner cover 2130 is configured to limit the position of the shape-changing capsule 2200, thereby limiting the maximum expansion state of the shape-changing capsule 2200, and defining that the dropper cover 2100 is fully assembled relative to the container bottle shoulder 1100. The air in the capsule cavity forms an expected vacuum negative pressure state, and a fixed amount of liquid is sucked.

[0071] In one embodiment, the tube channel of the liquid guide tube 2300 includes a main channel 2301 and an end channel 2302 connected in series. The end channel 2302 is arranged at the bottom of the liquid guide tube 2300, and the size of the end channel 2302 gradually decreases from the top to the bottom of the liquid guide tube 2300.
