[0002] In the prior art, lotion pumps are widely used in cosmetics and bath products. When the lotion is needed, the required lotion can be taken out by pressing the pump head. This method is convenient and hygienic.

[0003] The Chinese utility model patent "A New Lotion Pump" (application number: 201320109153.0) with authorization announcement number CN203127397U discloses a structure, which includes a push head, which is set on the upper end of the screw thread, and a clamping position is provided at the bottom of the push head corresponding to the inside of the screw thread. The bottom of the push head cooperates with the buckle line set at the upper end of the screw thread. A main column is provided inside the screw thread, and the top of the main column and the inside of the push head are chamfered and matched with each other. A secondary column is also provided below the main column, a spring is provided between the main column and the secondary column, and a straw is provided at the lower end of the screw thread. The lotion pump with the above structure adopts a locking connection between the bottom of the push head and the internal position of the screw thread. The switch can be switched by pressing the push head and rotating it 90 degrees. The inside of the push head and the top of the main column are chamfered to match each other. Suction and pumping effects can be generated when the push head moves up and down. The total height of the pump changes when the push head is locked or unlocked. Once the push head is opened, it cannot be closed. If you want to close it, you must press the head cap down, which will cause the liquid to flow out from the liquid outlet hole of the push head.

[0038] The present invention is further described in detail below with reference to the accompanying drawings.

[0039] like Figures 1 to 8As shown, the cosmetic container of this embodiment includes an inner bottle body 1, a pump body assembly 2, a head cap 3, a clamp ring 4, an outer bottle body 5, an inner sleeve 6, a clamping sleeve 7 and an adjustment mechanism 8. The inner bottle body 1 is used to hold fluid and can be replaced in this embodiment. The pump body assembly 2 is arranged at the upper port of the inner bottle body 1 and is used to pump out the fluid in the inner bottle body 1. The pump body assembly 2 is a conventional pump body structure used in cosmetic containers and will not be described in detail here. The head cap 3 is connected to the liquid outlet of the pump body assembly 2 and has a nozzle 31 for fluid output.

[0040] The clamp ring 4 is sleeved on the outer periphery of the pump body assembly 2 and is detachably connected to the top of the inner bottle body 1. The clamp ring 4 is clamped on the outer periphery of the pump body assembly 2 and is threadedly connected to the top of the inner bottle body 1. The lower part of the pump body assembly 2 is inserted into the inner bottle body 1, and the upper part of the pump body assembly 2 is located above the clamp ring 4. The head cap 3 is connected to the upper end of the pump body assembly 2, and a fourth guide strip 32 extending vertically is provided on the inner peripheral wall of the head cap 3. The upper part of the clamp ring 4 is provided with a third guide groove 41 that cooperates with the fourth guide strip 32 for guidance.

[0041] The outer bottle body 5 has a top opening 51, the inner sleeve 6 is arranged in the outer bottle body 5 so as to be movable up and down, the inner bottle body 5 is inserted in the inner sleeve 6, and the clamp ring 4 is detachably connected to the top of the inner sleeve 6 and moves up and down with the inner sleeve 6. The outer peripheral wall of the lower part of the clamp ring 4 is provided with a first clamping groove 42 arranged along the circumferential direction, and correspondingly, the inner peripheral wall of the inner sleeve 6 is provided with a clamping strip 61 elastically clamped with the first clamping groove 42. Figure 7 As shown, the inner sleeve 6 is provided with a notch 62 extending downward from the upper end, and the notch 62 divides the upper portion of the inner sleeve 6 into at least two elastic sheets 63 . The clamping strip 61 is arranged on the inner peripheral wall of the elastic sheet 63 .

[0042] like Figure 3 As shown, the above-mentioned clamping sleeve 7 is arranged in the outer bottle body 5 and is located at the upper part, and is used to limit the upward position of the inner sleeve 6. An annular groove 71 is opened on the outer peripheral wall of the clamping sleeve 7, and correspondingly, a convex ring 52 is arranged on the inner peripheral wall of the outer bottle body 5 to engage with the annular groove 71. When the head cap 3 is hidden in the outer bottle body 5, the lower end of the head cap 3 abuts against the upper end of the clamping sleeve 7, and the upper end surface of the head cap 3 is roughly flush with the upper edge of the outer bottle body 5.

[0043] The adjusting mechanism 8 of this embodiment can be movably arranged at the bottom of the outer bottle body 5 up and down, and is used to push the whole composed of the inner sleeve 6, the inner bottle body 5, the pump body assembly 2, the head cap 3, and the clamping ring 4 up and down so that the head cap 3 is exposed from the top opening 51 of the outer bottle body 5 or hidden in the outer bottle body 5. The adjusting mechanism 8 also has a limiting structure that can constrain the position of the inner sleeve 6 when the head cap 3 is exposed from the top opening 51 of the outer bottle body 5 or hidden in the outer bottle body 5.

[0044] Specifically, Figures 3 to 6As shown, the above-mentioned adjustment mechanism 8 includes a rotating sleeve 81, a base 82 and a first elastic member 83. The rotating sleeve 81 can move up and down and is arranged in the outer bottle body 5 and supported on the bottom of the inner sleeve 6 so as to rotate circumferentially. The base 82 can move up and down at the bottom of the outer bottle body 5. A plurality of vertically extending first guide strips 53 are arranged on the inner peripheral wall of the outer bottle body 5, and a first guide groove 54 is formed between two adjacent first guide strips 53. Correspondingly, a second guide strip 811 that can cooperate with the first guide groove 54 and limit the circumferential rotation of the rotating sleeve 81 when the rotating sleeve 81 moves up and down is arranged on the outer peripheral wall. The upper end surface of the base 82 is provided with a first convex tooth 821, and correspondingly, the lower end of the rotating sleeve 81 is provided with a second convex tooth 812 arranged opposite to the first convex tooth 821; the upper end surface of the first guide bar 53 is formed with a first inclined surface 531a and a second inclined surface 531b extending from bottom to top along the reverse direction of the rotating sleeve 81 and in a Z shape, and the heights of the upper ends of the first inclined surface 531a and the second inclined surface 531b are substantially equal. When the rotating sleeve 81 moves up and down, the first convex tooth 821 is arranged corresponding to the tooth gap 813 between two adjacent second convex teeth 812 and is offset in the rotation direction of the rotating sleeve 81; when the rotating sleeve 81 moves up to the state where the second guide bar 811 is separated from the first guide groove 54, the rotating sleeve 81 rotates with the base 82 moving up so that the second guide bar 811 is misaligned or aligned with the first guide groove 54. The second protruding teeth 812 are a plurality of triangular structures and are connected to each other at the lower end of the rotating sleeve 81. A triangular tooth gap 813 with the tip facing upward is formed between two adjacent second protruding teeth 812. There are four first protruding teeth 821 and they are spaced and distributed on the upper end surface of the base 82. The first protruding teeth 821 are triangular structures that can match the tooth gap 813. The bottom of the base 82 has a bottom plate 823. The rotating sleeve 81 has a supporting plate 814 that abuts against the bottom of the inner sleeve 6. The first elastic member 83 is a spring that is elastically compressed between the bottom plate 823 and the supporting plate 814 to keep the base 82 always moving downward.

[0045] In this embodiment, a third guide strip 822 extending vertically is provided on the outer peripheral wall of the base 82, and correspondingly, a second guide groove 55 guiding and cooperating with the third guide strip 822 is provided on the inner wall of the outer bottle body 5. This structure can not only guide the base 82 to move up and down, but also limit the base 82 in the circumferential direction to prevent it from rotating in the circumferential direction. A support ring 64 is provided on the outer peripheral wall of the inner sleeve 6, and a guide block 641 is convexly provided on the edge of the support ring 64. Correspondingly, a fourth guide groove 56 guiding and cooperating with the guide block 641 is provided on the inner peripheral wall of the outer bottle body 5. A second elastic member 9 is provided between the ferrule 7 and the support ring 64, which can keep the inner sleeve 6 always moving downward, and the second elastic member 9 is a spring.

[0046] The base 82 of this embodiment is equivalent to the switch member of the cosmetic container. When the cosmetic container of this embodiment is used, when the head cap 3 is completely hidden in the inner bottle body 5, the second guide strip 811 cooperates with the first guide groove 54, such as Figure 8 As shown, only the upper part of the first convex tooth 821 is located in the tooth gap 813 and is biased on one side of the tooth gap 813; the base 82 is pushed upward by hand, thereby pushing the inner sleeve 6, the inner bottle body 5, the pump body assembly 2, the head cap 3, and the clamping ring 4 to move upward. Since the base 82 and the rotating sleeve 81 can only move up and down at this time, the matching position of the first convex tooth 821 and the tooth gap 813 remains unchanged; when the lower end of the rotating sleeve 81 corresponds to the upper end of the first guide bar 53, the second guide bar 811 escapes from the first guide groove 54. At this time, the base 82 continues to move upward, and the matching position of the first convex tooth 821 and the tooth gap 813 changes. The first convex tooth 821 gradually gets stuck in the tooth gap 813 and drives the rotating sleeve 81 to rotate counterclockwise. When the first convex tooth 821 is completely stuck in the tooth gap 813, , no longer drives the rotating sleeve 81 to rotate circumferentially. At this time, the base 82 is loosened, and the base 82 is reset downward under the action of the first elastic member 83, and the lower end of the second guide strip 811 abuts against the first inclined surface 531a at the upper end of the first guide strip 53, and under the elastic force of the second elastic member 9 and the guiding action of the first inclined surface 531a, the rotating sleeve 81 continues to rotate counterclockwise by half the tooth gap 813. At this time, the lower end of the second guide strip 811 abuts against the limiting groove 532 formed by the lower end of the first inclined surface 531a and the first guide strip 53, so that the rotating sleeve 81 does not move downward, and the overall position of the inner sleeve 6, the inner bottle body 5, the pump body assembly 2, the head cap 3, and the clamping ring 4 is limited. At this time, the head cap 3 is exposed outside the outer bottle body 5, and the cosmetic container is in an open state. Pressing the head cap 3 can be used;

[0047] Moreover, in this state, the whole composed of the inner bottle body 5, the pump body assembly 2, the head cap 3, and the clamp ring 4 can be pulled upwards, so that the clamping strip 61 and the first clamping groove 42 can be separated from each other, so as to be taken out, and the inner bottle body 1 can be unscrewed from the clamp ring 4 for replacement;

[0048] When the cosmetics are not in use, the base 82 is pressed upward, and the first protruding tooth 821 at the upper end of the base 82 gradually fits into the tooth gap 813 to drive the rotating sleeve 81 to rotate. When the first protruding tooth 821 is completely inserted into the tooth gap 813, it no longer drives the rotating sleeve 81 to rotate circumferentially. At this time, the base 82 is released until the lower end of the second guide bar 811 is against the second inclined surface 531b at the upper end of the first guide bar 53, and under the elastic force of the second elastic member 9 and the guiding action of the second inclined surface 531b, the rotating sleeve 81 continues to rotate counterclockwise by half the tooth gap 813. At this time, the lower end of the second guide bar 811 is aligned with the first guide groove 54, and the inner sleeve 6, inner bottle body 5, pump body assembly 2, head cap 3, and retaining ring 4 as a whole move downward under the action of the second elastic member 9 until the head cap 3 is completely hidden in the outer bottle body 5.
