If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0052] See also Figures 1 to 13 As shown, the present application provides a dropper container, the dropper container includes a container body 1000 and a dropper body 2000, the container body 1000 has a container chamber inside, the container body 1000 is provided with a container bottle shoulder 1100, and the bottle mouth of the container bottle shoulder 1100 is connected to the container chamber. The container body 1000 can be sealed and connected to the container bottle shoulder 1100 by ultrasonic welding, 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 includes a dropper cover 2100, a deformable capsule 2200 and a liquid guide tube 2300. The interior of the dropper cover 2100 has a cover cavity. The deformable capsule 2200 is assembled in the cover cavity of the dropper cover 2100. The deformable capsule 2200 can be made of rubber and other materials. The deformable capsule 2200 has a capsule inner cavity. The deformable capsule 2200 is configured to have an expanded state and a contracted state. Therefore, when the deformable capsule 2200 is subjected to a force such as squeezing or pressing, the state can be changed due to the force, so that the deformable capsule 2200 is transformed from an expanded state to a contracted state, so that the air in the capsule inner cavity forms a vacuum negative pressure state.

[0054] The deformable sac 2200 has a liquid conducting end hole 2201 connected to the inner cavity of the sac, and the inner channel of the liquid conducting tube body 2300 is connected to the inner cavity of the deformable sac 2200 via the liquid conducting end hole 2201. Therefore, when the deformable sac 2200 is subjected to force to transform from an expanded state to a contracted state, so that the air in the inner cavity of the sac forms a vacuum negative pressure state, the vacuum negative pressure can absorb liquid through the inner channel of the liquid conducting tube body 2300, similar to manually squeezing the deformable sac 2200 to absorb liquid through the inner channel of the liquid conducting tube body 2300.

[0055] The difference is that the dropper cover 2100 is movably mounted on the container bottle shoulder 1100, and the dropper cover 2100 can move relative to the container bottle shoulder 1100. For example, the dropper cover 2100 is movably mounted on the container bottle shoulder 1100 by means of threaded rotation. When the dropper cover 2100 can move relative to the container bottle shoulder 1100, the dropper cover 2100 can drive the deformation capsule 2200 and the liquid guide tube body 2300 to move synchronously relative to the container body 1000 and the container bottle shoulder 1100. At this time, based on the relative to the container body 100 0 and the container bottle shoulder 1100 move synchronously, the deformable capsule 2200 can be configured to be used for direct or indirect force contact with the container body 1000. For example, when the deformable capsule 2200 is in the closed state (such as unscrewing clockwise) of the dropper cover 2100, the dropper cover 2100 squeezes the deformable capsule 2200 upward, compressing the air in the capsule cavity of the deformable capsule 2200. At this time, the deformable capsule 2200 is in a contracted state. When the dropper cover 2100 is separated (such as unscrewing counterclockwise), the compressed part of the deformable capsule 2200 returns to its original state.

[0056] As the deformable sac 2200 moves synchronously relative to the container body 1000 and the container shoulder 1100, the magnitude of the force generated by the force contact between the deformable sac 2200 and the container body 1000 will change. Different magnitudes of the force can cause the deformable sac 2200 to transition from the expanded state to the contracted state to different degrees. At the same time, the state of the vacuum negative pressure formed by the air in the sac body cavity will also change synchronously.

[0057] In one embodiment, when the dropper cover 2100 is movably assembled on the container bottle shoulder 1100, the process of the dropper cover 2100 moving relative to the container bottle shoulder 1100 is fixed from the beginning of the assembly of the dropper cover 2100 relative to the container bottle shoulder 1100 until the assembly of the dropper cover 2100 relative to the container bottle shoulder 1100 is completed. Therefore, during the entire assembly process, the magnitude of the force generated by the force contact of the deformable capsule 2200 relative to the container body 1000 is also fixed, and the fixed force will eventually cause the deformable capsule 2200 to present a fixed contracted state, and then the vacuum negative pressure state formed by the air in the capsule cavity is also fixed.

[0058] Therefore, when the dropper cover 2100 is assembled with respect to the container shoulder 1100, the air in the inner cavity of the capsule will form a predictable vacuum negative pressure state, and a fixed amount of liquid will be absorbed. When the dropper cover 2100 is separated from the container shoulder 1100 again, the force generated by the force contact between the deformable capsule 2200 and the container body 1000 will disappear, so that the deformable capsule 2200 will be transformed from the contracted state to the expanded state again, and the liquid will be absorbed based on the vacuum negative pressure state in the inner cavity of the capsule.

[0059] Since the vacuum negative pressure formed by the air in the inner cavity of the capsule is fixed, a fixed amount of liquid will be automatically absorbed each 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 a process to open the deformable capsule 2200 relative to the container body 1000 to synchronously absorb the expected amount of liquid, which is very convenient to operate.

[0060] The deformable sac 2200 can be directly or indirectly in force contact with the container body 1000 in a variety of ways. For example, when the dropper cover 2100 is movably assembled on the container bottle shoulder 1100, the deformable sac 2200 will be directly squeezed with the container body 1000. Alternatively, the length of the liquid guide tube 2300 is greater than or equal to the depth of the container chamber of the container body 1000. When the dropper cover 2100 is movably assembled on the container bottle shoulder 1100, the liquid guide tube body 2300 will gradually approach the bottom inner wall of the container chamber of the container body 1000. Therefore, the contact between the liquid guide tube body 2300 and the bottom inner wall of the container chamber of the container body 1000 can be utilized to make the deformable sac 2200 indirectly in force contact with the container body 1000.

[0061] Moreover, the bottom inner wall of the container chamber of the container body 1000 may also be provided with a liquid collecting groove 1001, and the liquid collecting groove 1001 is used to accommodate the bottom of the liquid guiding tube body 2300 when the liquid guiding tube body 2300 penetrates into the container chamber, so that the deformable capsule 2200 is configured to indirectly contact the liquid collecting groove 1001 through the liquid guiding tube body 2300. The deformable capsule 2200 is fixed in the dropper cover 2100, such as between the first cover 2110 and the second cover 2120, and the liquid guiding tube body 2300 is assembled on the deformable capsule 2200 to directly contact the liquid and the liquid collecting groove 1001.

[0062] At the same time, the bottom inner wall of the container chamber of the container body 1000 can also be presented as an inclined wall surface, so that the height gradually decreases in the direction of the liquid collecting groove 1001 and tilts downward, so that all the liquid on the bottom inner wall of the container chamber of the container body 1000 can be concentrated in the liquid collecting groove 1001, and when the bottom of the liquid guide tube body 2300 extends into the liquid collecting groove 1001, all the liquid can be absorbed to avoid waste of wall liquid.

[0063] In one embodiment, at least one locking fastener 2101 is disposed in the cover body cavity of the dropper cover 2100, and a locking portion 2102 is disposed at the end of the locking fastener 2101. The container shoulder 1100 of the container body 1000 is provided with at least one locking slide 1110, and the locking slide 1110 extends along the circumferential direction of the container shoulder 1100, and the number of extended circles can be one circle or more. At this time, the locking portion 2102 of the locking fastener 2101 can be configured to slide along the locking slide 1110, thereby locking the dropper cover 2100 and the container body 1000.

[0064] Therefore, when it is necessary to assemble or separate the dropper cover 2100 and the container body 1000, the locking portion 2102 of the locking fastener 2101 can be slid in or out along the locking slide 1110 by rotating. In this way, the dropper cover 2100 and the container body 1000 can be quickly assembled or separated, and the dropper cover 2100 and the container body 1000 can be quickly opened and closed. The user can quickly open or close the dropper cover 2100 and the container body 1000, and the operation is more convenient.

[0065] In one embodiment, the container shoulder 1100 of the container body 1000 is provided with at least one guide slide 1120, the guide slide 1120 is connected with the locking slide 1110, the locking portion 2102 of the locking fastener 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 portion 2102 is configured as an arc surface. Based on the above-mentioned guide slide 1120, the locking portion 2102 of the locking fastener 2101 can be quickly introduced into the locking slide 1110, especially when the surface of the locking portion 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, and realizing 360-degree rapid opening and closing.

[0066] In one embodiment, the dropper body 2000 includes a dropper rubber head 2400, which can be made of a deformable material such as rubber, and is disposed on the dropper cover 2100. The dropper rubber head 2400 has a tube head inner cavity, and the dropper rubber head 2400 is provided with a tube head cavity opening connected to the tube head inner cavity. The deformable capsule 2200 has an air guide end hole 2202 connected to the capsule inner cavity, and the tube head cavity opening of the dropper rubber head 2400 is sealed and connected to the air guide end hole 2202 of the deformable capsule 2200. Therefore, the capsule inner cavity of the deformable capsule 2200 and the tube head inner cavity of the dropper rubber head 2400 can form a closed integral inner cavity together.

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

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

[0069] For example, the edge of the air-conducting end hole 2202 of the deformation capsule 2200 and the edge of the tube head cavity opening of the dropper rubber tip 2400 are sealed and clamped in the compression 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 tip 2400 is sealed and connected with the air-conducting end hole 2202 of the deformation capsule 2200.

[0070] In one embodiment, an inner cover 2130 is disposed in the second chamber of the second cover body 2120, and the liquid guiding tube body 2300 is movably inserted into the inner cover 2130, wherein at least one limiting portion 2131 is disposed inside the inner cover 2130, and for example, the limiting portion 2131 is located at the bottom, top or middle of the inner cover 2130. At this time, the limiting portion 2131 of the inner cover 2130 is configured to be in limiting contact with at least one position of the deformable capsule 2200, and the maximum expansion state of the deformable capsule 2200 is limited by the mutual limiting contact, thereby limiting the assembly of the dropper cover body 2100 relative to the container bottle shoulder 1100, and the air in the inner cavity of the capsule will form a predictable vacuum negative pressure state to absorb a fixed amount of liquid.

[0071] In one embodiment, the inner channel of the liquid guiding tube body 2300 includes a main channel 2301 and an end channel 2302 connected to each other, and the end channel 2302 is located at the bottom of the liquid guiding tube body 2300, and the channel size of the end channel 2302 gradually decreases from the top to the bottom of the liquid guiding tube body 2300. For example, the channel diameter of the end channel 2302 gradually decreases to form a funnel-shaped channel, and this structure can effectively alleviate the problem of liquid spraying outward.

[0072] In one embodiment, the dropper container includes a scraper barrel 1200, the scraper barrel 1200 is disposed in the container bottle shoulder 1100, the scraper barrel 1200 is configured to be used to movably penetrate the liquid guide tube 2300, and the outer wall of the tube body of the liquid guide tube 2300 is configured to contact with at least a portion of the inner wall of the barrel of the scraper barrel 1200. Therefore, the scraper barrel 1200 can be used to scrape off the residual liquid in the liquid guide tube 2300, so as to fully utilize the liquid. For example, a scraper member 1210 is disposed at the bottom of the scraper barrel 1200, and the outer wall of the tube body of the liquid guide tube 2300 is configured to contact with the scraper member 1210, and the scraper member 1210 can be a plate-shaped, ring-shaped, or other structure.
