[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.
[0032] like Figures 1 to 6 As shown, this invention provides a cosmetic dropper. To facilitate easy opening of the inner shell 2 for users to replace cosmetic products, and to facilitate the operation of the cosmetic dropper, as well as to prevent accidental placement of the cosmetic dropper when not in use, the three settings are designed as one-piece droppers, greatly simplifying user operation. In this embodiment, the cosmetic product is eye cream, but it can also be other cosmetic products.
[0033] Specifically, it includes an outer shell 1, which has a first cavity 101 extending vertically; an inner shell 2, which has a second cavity 201 for holding cosmetic products; and an elastic pump assembly 3 for driving the cosmetic products is installed at the lower end of the inner shell 2, with an outlet 301 at the lower end of the elastic pump assembly 3. The inner shell 2 can be inserted into the first cavity 101 of the outer shell 1, and by pressing the inner shell 2 under the action of the elastic pump assembly 3, the cosmetic products are expelled from the outlet 301. There is also a rotating structure between the inner shell 2 and the outer shell 1, allowing the inner shell 2 to be quickly opened from the outer shell 1 and enabling dropper operation. Furthermore, for ease of pressing, the upper end of the inner shell 2 is exposed outside the inner shell 1.
[0034] The rotational structure between the inner shell 2 and the outer shell 1 is specifically described as follows: The upper outer wall of the inner shell 2 is provided with a first protrusion 202 and a second protrusion 203 that are staggered in height; the upper port of the inner wall of the outer shell 1 is provided with a first channel 102 for the first protrusion 202 to slide into or out, a third protrusion 103 corresponding to the second protrusion 203 and serving to restrict the upward movement of the inner shell 2, and a second channel 104 for the first protrusion 202 to slide downward; the rotational structure is formed by the cooperation of the first protrusion 202, the second protrusion 203, the first channel 102, the third protrusion 103, and the second channel 104.
[0035] When the first protrusion 202 is inserted into the first channel 102, the second protrusion 203 and the third protrusion 103 are staggered, so that the inner shell 2 can be opened quickly, realizing the function of first-stage disassembly or assembly.
[0036] When the first protrusion 202 is rotated into the second channel 104, the third protrusion 103 is located above the second protrusion 203. At this time, the inner shell 2 can only move downwards, and the inner shell 2 realizes the working state of the dropper and realizes the second working function.
[0037] Therefore, it can be designed in two modes, with both quick-opening and dropper operation functions.
[0038] To facilitate positioning, after the first protrusion 202 is fully inserted into the first channel 102, a very small part of the second protrusion 203 is located below the third protrusion 103. When it is pressed in, there will be a click to achieve positioning, so as to facilitate the next rotation.
[0039] Prioritized for ease of rotation and to serve as a spacer, the first channel 102 and the second channel 104 are separated by a fourth protrusion 105.
[0040] The inner wall of the outer shell 1 is also provided with a third channel 106 at the port, into which the first protrusion 202 can slide. The third channel 106 is at the same height as the first channel 102, further forming the rotating structure.
[0041] When the first protrusion 202 is rotated into the third channel 106, the third protrusion 103 is located between the second protrusion 203 and the first protrusion 202, and the inner shell 2 is locked inside the outer shell 1 and cannot move, thus realizing the third locking function.
[0042] Specifically, it should be noted that, in order to facilitate the downward movement of the inner shell 2, the second channel 104 is longer than the first channel 102 and the third channel 106. In this embodiment, the first channel 102 and the third channel 106 have the same depth.
[0043] Prioritizing ease of rotation and serving as a spacer, the second channel 104 and the third channel 106 are separated by a fifth protrusion 107. In other words, the first channel 102, the second channel 104, and the third channel 106 are designed to be adjacent to each other for convenient rotation.
[0044] To ensure greater stability during rotation, a sixth protrusion 108 is provided on one side of the upper inner wall of the outer shell 1. The sixth protrusion 108 is flush with the third protrusion 103 at the same height and is located below the third channel 106. A seventh protrusion 204 is provided on one side of the upper outer wall of the inner shell 2. The seventh protrusion 204 is flush with the second protrusion 203 at the same height.
[0045] Specifically, the first protrusion 202 is higher than the second protrusion 203 and the seventh protrusion 204.
[0046] Due to the addition of the sixth protrusion 108 and the seventh protrusion 204, the corresponding structures for the first gear disassembly / assembly function, the second gear operation function, and the third gear locking function are as follows:
[0047] When the first protrusion 202 is inserted into the first channel 102, the second protrusion 203 and the third protrusion 103 are misaligned, and the seventh protrusion is also misaligned with the third protrusion 103 and the sixth protrusion 108, so that the inner shell 2 can be opened quickly to realize the function of first-stage disassembly or assembly.
[0048] When the first protrusion 202 is rotated into the second channel 104, the third protrusion 103 is located above the second protrusion 203, and the sixth protrusion 108 is located above the seventh protrusion 204. At this time, the inner shell 2 can only move downwards, and the inner shell 2 realizes the working state of the dropper and realizes the second working function.
[0049] When the first protrusion 202 is rotated into the third channel 106, the third protrusion 103 and the sixth protrusion 108 are located together between the second protrusion 203, the seventh protrusion 204 and the first protrusion 202, and the inner shell 2 is locked inside the outer shell 1 and cannot move, thus realizing the third locking function.
[0050] As a specific description of the structure of the elastic pump body assembly 3, the elastic pump body assembly 3 includes a connector 302, a spring pump body 303, and a sealing sleeve 304; the sealing sleeve 304 is a hollow structure and is sealed and fitted onto the lower port of the inner shell 2; the upper end of the spring pump body 303 passes through the hollow part of the sealing sleeve 304 and is inserted into the inner shell 2, while the outer shell of the spring pump body 303 is also inserted and fixed to the inner shell 2; the lower end of the spring pump body 303 is sealed and inserted and fixed to the connector 302, and the outlet 301 is located at the connector 302; the connector 302 is exposed outside the outer shell 1.
[0051] To prevent cosmetics from leaking out, the cosmetic dropper also includes a stopper 4, which is slidably and sealed inside the second cavity 201. Under the action of the elastic pump assembly 3, the stopper 4 will gradually move downward in the inner shell 2 as the cosmetics are reduced.
[0052] To facilitate the installation of cosmetics, the inner shell 2 includes a main shell 205 and a detachable upper cover 206, wherein the upper cover 206 has a side hole 207 for ventilation.
[0053] Furthermore, the fourth protrusion 105 and the fifth protrusion 107 are curved surfaces, which facilitates rotation.
[0054] Specifically, it is worth mentioning that in this embodiment, the first protrusion 202, the second protrusion 203, the seventh protrusion 204, and the side hole 207 are all provided on the upper cover 206.
[0055] Preferably, in order to achieve stable rotation of the inner shell 2, the rotation structure is provided in two symmetrical arrangements. That is, the first protrusion 202, the second protrusion 203, and the seventh protrusion 204 are symmetrically arranged in two sets. Of course, the first channel 102, the third protrusion 103, the second channel 104, the fourth protrusion 105, the third channel 106, the fifth protrusion 107, and the sixth protrusion 108 are also symmetrically arranged in two sets.
[0056] Of course, it also includes end cap 5 and connecting cap 6, the connecting cap 6 being installed at the lower end of the housing 1, and the end cap 5 being installed at the lower end of the connecting cap to cover the connector 302.
[0057] When in use, put cosmetics into the inner shell 2, then put in the stopper 4, then put on the top cover 206, then switch to the second working function, press down on the inner shell 2, and under the action of the spring pump body 303, the cosmetics flow into the sealing sleeve 304 and the spring pump body 303 in sequence, and flow out from the connector 302.
[0058] like Figure 7 As shown, when the inner shell 2 is inserted, when the first protrusion 202 is inserted into the first channel 102, the second protrusion 203 and the third protrusion 103 are misaligned, and the seventh protrusion is also misaligned with the third protrusion 103 and the sixth protrusion 108, so that the inner shell 2 can be opened quickly to realize the function of first-stage disassembly or assembly.
[0059] like Figure 8 As shown, when the first protrusion 202 is rotated into the second channel 104, the third protrusion 103 is located above the second protrusion 203, and the sixth protrusion 108 is located above the seventh protrusion 204. At this time, the inner shell 2 can only move downwards, and the inner shell 2 realizes the working state of the dropper and realizes the second working function.
[0060] like Figure 9 As shown, when the first protrusion 202 is inserted into the third channel 106, the third protrusion 103 and the sixth protrusion 108 are located together between the second protrusion 203, the seventh protrusion 204 and the first protrusion 202. The inner shell 2 is locked inside the outer shell 1 and cannot move, realizing the third locking function, which facilitates transportation and storage and prevents misoperation.
[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0062] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any appropriate changes and variations made to the above embodiments within the essential spirit of the present invention fall within the scope of protection claimed by the present invention.
