Description

Technical Field

[0001] The present invention belongs to the technical field of storage of daily chemical products, and particularly relates to a liquid dispenser and a container having the liquid dispenser. Background Art

[0002] In the cosmetics industry, some liquid cosmetics need to be taken with a lid similar to a dropper structure. Ordinary lids similar to the dropper structure all adopt a structure in which a straw, a piston, a button and a spring cooperate to realize the taking of liquid cosmetics. Although the purpose of taking is achieved, when recycling the discarded cosmetic container, since the spring is made of metal material and the other components are basically made of plastic material, the container needs to be disassembled first during recycling, and the metal spring needs to be taken out before recycling separately, which results in an increase in the recycling process and an increase in time and labor costs. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a liquid dispenser that can be made of the same material as a whole and is convenient for recycling.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A liquid dispenser includes

[0005] a piston that can move up and down;

[0006] a fixing member having a liquid suction cavity for the piston to move up and down therein;

[0007] a liquid suction device that can move up and down, for driving the piston to move up and down in the liquid suction cavity;

[0008] a rotating sleeve that can rotate back and forth, for driving the liquid suction device to move up and down;

[0009] a housing, which is in non-rotating fit with the rotating sleeve;

[0010] When the housing is rotated, the rotating sleeve will rotate under the drive of the housing, and drive the liquid suction device to move up and down, and then drive the piston to move up and down along the liquid suction cavity to realize the taking and placing of liquid;

[0011] By setting the above structure, the rotating sleeve can be driven to rotate by rotating the outer shell, thereby driving the liquid suction device to move up and down, and the up and down movement of the liquid suction device will drive the piston to move up and down along the liquid suction chamber; wherein, when the piston rises along the liquid suction chamber, the pressure in the liquid suction chamber decreases, and the liquid can be sucked in to achieve the absorption of the liquid; and when the piston descends along the liquid suction chamber, the pressure in the liquid suction chamber increases, and the liquid can be discharged to achieve the taking of the liquid; it can be seen that through the coordinated arrangement of the fixing part, the outer shell, the rotating sleeve and the liquid suction device, the taking of the liquid can be achieved by rotating the outer shell, and there is no need to install a metal spring, so that the entire liquid picker and placer can be made of the same material (such as plastic), which saves material costs and is also convenient for recycling, so that the liquid picker and placer does not need to be disassembled during recycling, thereby improving the recycling efficiency and reducing the time cost; and it breaks through the conventional inherent thinking of using button springs to achieve liquid picking and placing, and has unexpected effects.

[0012] Furthermore, the liquid suction device includes an elastic portion that is at least partially elastically deformable; through the arrangement of the above structure, it is more convenient to discharge the liquid and more convenient to use.

[0013] Furthermore, when the liquid pick-up and delivery device is in an unused state, the elastic part remains uncompressed; with the above structure, the piston can move up and down in the liquid suction cavity driven by the liquid suction device. During the movement, the elastic part will never deform, so that when the liquid pick-up and delivery device is not in use, the elastic part also always remains undeformed, making it difficult for the elastic part to age or be damaged quickly due to long-term extrusion or stretching, ensuring that the elastic force of the elastic part is more durable, extending its service life, and further enabling the elastic part to be made of the same material as other components (such as plastic), making the recycling of the liquid pick-up and delivery device more convenient, without the need to separate different materials for recycling, greatly improving the recycling efficiency and reducing the recycling cost; because the elastic parts in conventional liquid pick-up and delivery devices are all made of metal springs, while other components are made of plastic materials, which is the main reason for the need to separate materials during recycling; when a conventional liquid pick-up and delivery device is tightly sealed with the bottle body, the metal spring is always in a compressed state. Due to the strong elastic force of the metal spring and its resistance to aging, it can still maintain its elastic force even when in a compressed state for a long time; if a simple metal spring is replaced with an elastic plastic part, since the plastic has a weak elastic force and is prone to aging, if the plastic part is in a compressed state for a long time, the elastic force of the plastic part will quickly disappear, greatly shortening the service life of the elastic plastic part and causing the liquid pick-up and delivery device to fail to reach its due service life; through the above analysis, it can be seen that the present application precisely through the above structure, when the liquid pick-up and delivery device is not in use, the elastic part always remains undeformed, making it difficult for the elastic part to age and having a longer service life, and further making it possible to make the entire liquid pick-up and delivery device from the same material, achieving the purpose of convenient recycling, high recycling efficiency, and low cost, which is obviously not obtained by simply replacing conventional means.

[0014] Furthermore, the liquid suction device includes a compressive part connected to the elastic part and a convex block connected to the compressive part. The convex block can move up and down back and forth along a track, and the elastic part moves up and down synchronously with the convex block under the drive of the convex block; with the above structure, the rotational cooperation between the rotating sleeve and the liquid suction device is realized, and the rotation of the rotating sleeve can drive the liquid suction device to rotate and rise at the same time.

[0015] Furthermore, the track includes an upper guiding surface for driving the convex block to descend and a lower guiding surface for driving the convex block to ascend; through the setting of the upper and lower guiding surfaces, the function of driving the entire liquid suction device to move up and down is realized, making it unnecessary to use a spring to provide the lifting force or the descending force, ensuring that the elastic part is mostly in a natural state or a slightly deformed state, thereby delaying the aging of the elastic part and enabling the elastic part to be made of plastic.

[0016] Furthermore, it also includes a connecting block connected to the anti-pressure part and a slide groove that cooperates with the connecting block for sliding and stopping rotation; when the protrusion rises and falls back and forth along the track, it drives the connecting block to slide back and forth along the slide groove; through the setting of the above structure, the anti-rotation cooperation between the fixing part and the anti-pressure part is achieved, and the structure is simple and effective.

[0017] Furthermore, the fixing member includes a fixed spacer ring, and the liquid suction device includes a pressing protrusion connected to the elastic part; when the protrusion descends to a preset height along the track, the fixed spacer ring conflicts with the pressing protrusion; through the above-mentioned structural setting, after the liquid suction device descends to the specified position, the pressing protrusion cannot descend, thereby ensuring that the elastic part will never be compressed.

[0018] Furthermore, the elastic part includes a lower ring body connected to the connecting block, an elastic strip provided on the lower ring body, and an upper ring body connected to the elastic strip.

[0019] Furthermore, the elastic strip is arranged in an arc-shaped structure, which facilitates deformation and has better elasticity.

[0020] The present invention also provides a container with high recycling efficiency and low cost;

[0021] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a container, including a container body and a cover body; the cover body is the above-mentioned liquid access device.

[0022] To sum up, the present invention, through the arrangement of the above-mentioned structure, enables the piston to move up and down in the liquid suction chamber driven by the liquid suction device while taking out the liquid, so that the entire liquid accessor and dispenser can be made of the same material (such as plastic), thereby achieving more convenient, efficient and low-cost recycling.

[0036] As Figure 1-13 shown, a liquid pick-up and placement device includes a piston 1, a fixing member 2, a rotating sleeve 3, a liquid suction device, an outer shell 7, a button 8 and a button housing 9; the fixing member 2 is made of PVC material or other materials, and the fixing member includes a connecting groove 22, a clamping edge 23, a connecting column 24, a notch 25, a ring edge 26 and a fixing body 29; the connecting groove is opened at one end of the fixing body, and at least part of its inner wall is provided with threads, so as to facilitate the connection, fixation and sealing between the liquid pick-up and placement device and the bottle body; the clamping edge 23 is formed by extending outward from at least part of the surface of the bottom of the connecting groove, and is arranged in an annular structure, and its outer diameter is slightly larger than the inner diameter of the bottle mouth, so as to form an interference fit with the bottle mouth, facilitating the sealing fit between the liquid pick-up and placement device and the bottle body; preferably, a clamping edge arc surface is opened on the outer side of the upper end of the clamping edge, facilitating the clamping of the clamping edge into the bottle mouth; the connecting column 24 is also formed by extending outward from at least part of the surface of the bottom wall of the connecting groove, and is arranged in a columnar structure. Preferably, a connecting arc surface is opened at the end of the connecting column, so as to facilitate the connection and fixation between the connecting column and the straw 100, and facilitate the suction of the items in the bottle body into the straw and taking them out; a plurality of notches 25 are opened on the inner wall of the end of the connecting groove, and the plurality of notches are evenly arranged circumferentially along the inner wall of the connecting groove. The notches can be opened in the shape of a rectangle, a triangle, a trapezoid or other shapes; at least part of the surface of the outer wall of the fixing body extends outward to form a ring edge 26, and the ring edge surrounds the fixing body for one week, and the ring edge is located on the side close to the connecting groove opened on the fixing body.

[0037] Further, a liquid suction cavity 20 is formed at one end of the fixed body 29 away from the connection groove 22. A through groove is formed in the middle of the connecting column 24, so that a straw connected to the connecting column can communicate with the liquid suction cavity through the through groove; the piston 1 is installed in the liquid suction cavity and can move back and forth along the liquid suction cavity; the piston includes a piston body 10, a piston outer ring 11, a piston connecting portion 12, a piston ring edge 13 and a piston rib 14; the piston body is formed in a cylindrical structure and is made of PVC material or other materials; at least part of the outer surface of the piston body extends outward to form the piston connecting portion 12, and the piston connecting portion is annular; at least part of the surface of the piston connecting portion extends outward to form the piston outer ring 11, and the piston outer ring is formed in an annular structure and surrounds the outside of the piston body and is connected to the piston body through the piston connecting portion. Except for the part connected by the piston connecting portion, there is a gap between the inner surface of the piston outer ring and the outer surface of the piston body, so that the piston outer ring has sufficient deformation space; at least part of the surface at both ends of the piston outer ring extends outward to form the piston ring edge 13, and the piston ring edge is formed in a flared structure, so that after the piston is installed in the liquid suction cavity 20, the piston ring edge can always be in close contact with the inner wall of the liquid suction cavity, realizing the sealing fit between the piston and the inner wall of the liquid suction cavity, so that the lifting of the piston can change the pressure in the liquid suction cavity, realizing the suction and discharge of cosmetics. At the same time, because the piston ring edge can undergo elastic deformation, it will not cause too much resistance to the lifting of the piston; at least part of the surface of the lower end surface of the piston body (close to the bottom surface of the liquid suction cavity) extends outward to form the piston rib 14, and the piston rib is formed in a "cross" structure.

[0038] Specifically, the liquid suction device is installed on the fixing member 2 and can move up and down relative to the fixing member; the liquid suction device includes a pressing part 4, a pressure-resistant part 5 and an elastic part 6. The pressure-resistant part 5 includes a pressure-resistant body 50 and a convex block 51. The pressure-resistant body is formed in an annular structure and is made of PVC material or other materials. The pressure-resistant body is sleeved outside the fixing body 29 and can slide back and forth relative to the fixing body; at least part of the outer surface of the pressure-resistant body extends outward to form the convex block 51; the pressing part 4 includes a pressing body 40, a pressing convex part 41, a pressing convex edge 42 and a pressing snap ring 43; the pressing body 40 is formed in a hollow cylindrical structure and is made of PVC material or other materials. Its outer diameter is less than or equal to the inner diameter of the liquid suction cavity 20, so that at least part of the pressing body can penetrate into the liquid suction cavity and can slide back and forth relative to the liquid suction cavity; at least part of the lower end surface of the pressing body extends outward to form the pressing convex part 41, and the pressing convex part is formed in a hollow cylindrical structure; at least part of the upper end surface of the piston body 10 is recessed inward to form a piston groove 15, and the inner diameter of the piston groove is less than or equal to the outer diameter of the pressing convex part, so that the pressing convex part can be inserted into the piston groove, enabling the piston to form an interference fit with the pressing part, so that the piston can move up and down with the lifting of the pressing part; preferably, at least part of the outer surface of the outer wall of the pressing convex part extends outward to form the pressing snap ring 43, and at least part of the inner surface of the inner wall of the piston groove 15 extends outward to form a piston snap ring 16. Through the clamping between the piston snap ring and the pressing snap ring, the anti-separation fit between the piston and the pressing part is realized, ensuring that the piston will not separate from the pressing part during the process of moving up and down with the pressing part, and the cooperation is more stable; at least part of the outer surface of the outer wall of the pressing body 40 near the upper end extends outward to form the pressing convex edge 42; and at least part of the end surface of the end of the fixing body 29 away from the connecting groove 22 is recessed inward to form a movable ring groove 27. The movable ring groove surrounds the outside of the liquid suction cavity, and a fixed spacer ring 28 is formed between the movable ring groove and the liquid suction cavity; when the pressing body 40 slides into the liquid suction cavity by a certain distance, the upper end surface of the fixed spacer ring will abut against the lower end surface of the pressing convex edge 42, thereby preventing the pressing part from completely entering the liquid suction cavity.

[0039] Furthermore, the elastic part 6 includes an elastic strip 61, an upper ring body 60, a lower ring body 62 and a connecting block 63; the upper ring body 60 is formed by extending outward from at least part of the lower surface of the pressing convex edge 42, and is arranged in a ring structure. There is a gap between the inner side surface of the upper ring body and the outer surface of the pressing body, so that the upper end of the fixed spacer ring 28 can penetrate into this gap; the elastic strip 61 is arranged in an arc structure. Preferably, the elastic strip in this application is arranged in a spiral structure of a half circle, and two elastic strips are installed in total, and are evenly arranged along the circumferential direction of the upper ring body; the upper end of the elastic strip is connected to the upper ring body, and the lower end is connected to the lower ring body; when the pressing part is pressed and the elastic strip is compressed, since the elastic strip is arranged in a spiral structure of a half circle, the part of the elastic strip close to the upper ring body and the part close to the lower ring body will preferentially undergo elastic deformation, so that the elastic strip requires less pressure to cause elastic deformation, making it easier for the user to press. Moreover, the elastic force of the elastic strip is greater than the frictional force between the piston and the liquid suction cavity, and at the same time, the elastic strip has sufficient elastic force to push the piston up. And because it is the part of the elastic strip close to the upper ring body and the part close to the lower ring body that will preferentially undergo elastic deformation, the elastic force of the elastic strip is more persistent, less likely to age, and has a longer service life; the lower ring body 62 is connected to the lower end of the elastic strip 61, and the lower ring body is arranged in a ring structure and is located in the movable ring groove 27 and can move up and down in the movable ring groove; at least part of the outer surface of the lower ring body extends outward to form a connecting block 63; and a sliding groove 21 is opened on the fixed body 29, and the connecting block passes through this sliding groove and is connected to the pressure-resistant body 50, and the connecting block can slide back and forth along the sliding groove, so that the liquid suction device composed of the pressing part 4, the pressure-resistant part 5 and the elastic part 6 (that is, the pressing part, the pressure-resistant part and the elastic part are of an integral structure) can move up and down as a whole and drive the piston to move up and down together.

[0040] In other embodiments, the pressing part, the elastic part and the pressure-resistant part can also be of a split structure and are connected and fixed by means of clamping, screwing, bonding or other means.

[0041] Specifically, the rotating sleeve 3 includes a rotating sleeve body 30, a track 31, a rotating clamping portion 32, a rotating convex edge 33 and a rotating hook 34; the rotating sleeve body 30 is provided in a hollow cylindrical structure and is made of PVC material or other materials. The rotating sleeve body is sleeved on the outside of the pressure-resistant body 50, and the inner diameter of the rotating sleeve body is equal to or slightly larger than the outer diameter of the pressure-resistant body, so that the rotating sleeve body can rotate and rise and fall relative to the pressure-resistant body; the track 31 is provided on the rotating sleeve body 30 and is provided in a spiral structure. The track includes a first section body 311, a second section body 31 2, the third section 313 and the fourth section 314; wherein the second section is opened in an arc-shaped structure, the first section and the third section are both horizontal sections, respectively connected to the two ends of the second section, and the fourth section is connected to the third section, opened in a vertical state, and is an open groove; wherein the upper wall of the second section 312 is an upper guide surface 3121, and the lower wall of the second section 312 is a lower guide surface 3122; when the rotating sleeve is arranged on the outside of the anti-pressure part, the convex block 51 on the anti-pressure part is inserted into the track, so that when the rotating sleeve rotates, the convex block The block will move along the track. When the protrusion is located in the first section, the anti-pressure part is at the highest point, and when the protrusion is located in the third section, the anti-pressure part is at the lowest point. When the protrusion moves back and forth along the second section, the anti-pressure part will rise and fall with the movement of the protrusion (when the upper guide surface applies external force to the protrusion, it will drive the protrusion to fall; when the lower guide surface applies external force to the protrusion, it will drive the protrusion to rise), thereby driving the elastic part, the pressing part and the piston connected to the anti-pressure part to rise and fall together. When the rotating sleeve needs to be removed, it only needs to make the protrusion pass through the third section. When the four-segment body is released from the slide groove, the rotating sleeve can be separated from the pressure-resistant part; at least part of the outer surface of the rotating sleeve extends outward to form a convex strip, and multiple convex strips are evenly arranged along the circumference of the rotating sleeve, and a gap is left between two adjacent convex strips, thereby forming a rotating clamping part 32; at least part of the outer surface of the rotating sleeve extends outward to form a rotating convex edge 33, and the rotating convex edge can surround the rotating sleeve body, or can be multiple convex edges evenly arranged along the circumference of the rotating sleeve body; at least part of the surface of the upper end of the inner wall of the rotating sleeve extends outward to form a rotating hook 34.

[0042] In other embodiments, the protrusion 51 can also be opened on the inner wall of the rotating sleeve 3, and the track 31 can be opened on the pressure-resistant part 5, which can also realize the rotation and lifting coordination between the rotating sleeve and the resistance part, so that the resistance part can be lifted and lowered with the rotation of the rotating sleeve.

[0043] In other embodiments, the sliding groove 21 can also be formed on the rotating sleeve 3, and then a convex block 51 is formed on the outer wall of the pressure-resistant part 5. Through the cooperation of the convex block and the sliding groove, while forming an anti-rotation fit between the pressure-resistant part and the rotating sleeve, the pressure-resistant part can also move up and down relative to the rotating sleeve; of course, it is also possible to form the sliding groove on the pressure-resistant part and the convex block on the inner wall of the rotating sleeve; then the track 31 is formed on the fixing part, and the connecting block 63 passes through the track, so that the lifting of the pressure-resistant part is realized through the cooperation between the connecting block and the track.

[0044] It should be noted that the liquid suction device in the present application can be used as an independent technical solution, or can be arbitrarily combined with other modules in the present application to form a new technical solution, or can be arbitrarily combined with other existing modules to form a new technical solution.

[0045] Specifically, the housing 7 includes a housing body 70, a first housing groove 71, a second housing groove 72, a housing edge 73 and a housing clamping edge 74; the housing body 70 is made of PVC material or other materials, and the housing body is formed in a hollow cylindrical structure and sleeved outside the rotating sleeve 3; at least part of the outer surface at the lower end of the housing body extends outward to form a housing convex part 75, and the housing convex ring is formed in a structure with a smaller upper part and a larger lower part, and the outer wall is arc-shaped, so that the overall appearance is more beautiful and the installation is more stable; the housing edge 73 is formed by at least part of the inner wall at the lower end of the housing body 70 extending outward. When the fixing part 2 is installed in the housing, the clamping edge 23 can just abut against the housing edge, and the lower end surface of the fixing part is flush with the lower end surface of the housing; the first housing groove 71 is formed by at least part of the inner wall surface of the housing body recessing inward, and at least part of the surface of the bottom wall of the first housing groove extends outward to form a plurality of convex strips 76, and there is a gap between adjacent two convex strips. The combination of the plurality of convex strips and the gaps is evenly arranged circumferentially along the bottom wall of the first housing groove. After the rotating sleeve 3 is installed in the housing 7, the rotating clamping part 32 can just be embedded in the first housing groove, and the convex strips forming the rotating clamping part can just be embedded in the gaps between adjacent two convex strips formed on the bottom wall of the first housing groove. Correspondingly, the convex strips formed on the bottom wall of the first housing groove can just be embedded in the gaps between adjacent two convex strips forming the rotating clamping part, so that an anti-rotation fit is formed between the housing and the rotating sleeve; the housing clamping edge 74 is formed by at least part of the inner wall of the housing body extending outward, and the cross section is formed in a semi-circular structure; a second housing groove 72 is formed between the housing clamping edge and the first housing groove, and the rotating convex edge 33 is embedded in the second housing groove, and the rotating convex edge is clamped through the cooperation between the second housing groove and the housing edge, so as to realize the anti-disengagement fit between the housing and the rotating sleeve.

[0046] Specifically, the button housing 9 includes a button housing body 90, a first convex edge 91, a second convex edge 92 and button housing bars 93. The button housing body 90 is made of PVC material or other materials, and is formed in an arc-shaped structure, bulging upward, which is more convenient to press and has a better hand feeling. The first convex edge 91 is formed by extending outward from at least part of the lower surface of the outer edge of the button housing body 90, and its outer diameter is smaller than the inner diameter of the housing 70. The second convex edge 92 is formed by extending outward from at least part of the surface of the lower surface of the button housing body 90. The button housing bars 93 are formed by extending outward from at least part of the surface inside the second convex edge, and a plurality of button housing bars are evenly arranged along the circumference of the second convex edge, with a gap left between adjacent two button housing bars.

[0047] Specifically, the button 8 includes a button body 80, a first button edge 81, a second button edge 82, a button catch 83, a button strip 84, a button boss 85 and a button groove 86; the button body 80 is made of PVC material or other materials, is formed in an arc structure and protrudes upward, so that when the button housing covers the button, the upper surface of the button body fits with the lower surface of the button housing body; at least part of the lower surface of the outer edge of the button body extends downward to form the first button edge 81, and the outer diameter of the first button edge is slightly larger than the inner diameter of the second convex edge 92, so that the first button edge can form an interference fit with the second convex edge; at least part of the outer surface of the lower end of the first button edge extends outward and then downward to form the second button edge 82, and a step groove is formed at the junction of the second button edge and the first button edge; and the outer diameter of the second button edge is smaller than the inner diameter of the rotating sleeve 3, and at least part of the inner diameter of the second button edge is larger than the outer diameter of the fixed body 29; at least part of the outer surface of the lower end of the second button edge extends outward to form the button catch 83, so that when the button 8 is inserted into the upper end of the rotating sleeve 3, the button catch cooperates with the rotating catch, realizing the anti-disengagement fit between the button and the rotating sleeve; preferably, the inner wall of the second button edge is formed in an inclined state, and the diameter gradually increases from the end close to the first button edge to the end far from the first button edge, so that when the button is pressed, the distance between the inner surface of the second button edge and the outer surface of the fixed body 29 gradually decreases until they come into contact with each other, thus playing a role in decelerating the button and reducing the noise or abnormal noise generated by the mutual impact of each component; at least part of the outer surface of the first button edge extends outward to form the button strip 84, and a plurality of button strips are arranged evenly along the circumference of the first button edge, and there is a gap between adjacent two button strips; when the button 8 is connected to the button housing 9, the button strip will be embedded between adjacent two button housing strips 93, and the button housing strip will be embedded between adjacent two button strips, thus realizing the anti-rotation fit between the button and the button housing; at least part of the lower surface of the button body extends outward to form the button boss 85, and a pressing groove 44 is formed on the pressing body 40, and the outer diameter of the button boss is slightly larger than the inner diameter of the pressing groove, so that after the button boss is inserted into the pressing groove, the two can form an interference fit; a button groove 86 is formed between the button boss and the first button edge, and the pressing body can just be placed in the button groove.

[0048] Operation instructions during use: When the liquid dispenser is not in use, it is in a state of being tightly screwed with the bottle body. At this time, when the outer shell 7 is turned, the outer shell will drive the rotating sleeve 3 to rotate. The rotation of the rotating sleeve 3 will cause the bump 51 placed in the track 31 to move along the track. As the rotating sleeve continues to rotate, the bump rises along the second section 312, which will drive the pressure-resistant part 5 to rise, thereby driving the elastic part 6, the pressing part 4, the piston 1, the button 8 and the button housing 9 connected to the pressure-resistant part 5 to rise. As the piston 1 rises, a negative pressure is formed in the liquid suction cavity 20, and the cosmetics in the bottle body will be sucked into the straw connected to the liquid suction cavity, realizing the suction of cosmetics; when the bump 51 enters the first section 311 and then the outer shell 7 is continuously rotated, the screwing connection between the fixing part 2 and the bottle body will be released, and the cover can be removed from the bottle body; at this time, since the pressure-resistant part 5, the elastic part 6, the pressing part 4, the piston 1, the button 8 and the button housing 9 have all risen, the fixed spacer ring 28 has withdrawn from the gap between the upper ring body 60 and the pressing body 40, and there is also enough space between the upper edge of the fixed body and the lower edge of the first button edge, so that the button can be freely pressed. At this time, when the button housing 9 is pressed, it will drive the button 8 to descend, thereby driving the pressing part 4 to descend and compress the elastic part 6, and further driving the piston 1 to descend, increasing the pressure in the liquid suction cavity, and squeezing out the cosmetics in the straw connected to the liquid suction cavity, realizing the use of cosmetics; at this time, when the external force is withdrawn, the piston 1, the pressing part 4, the button 8 and the button housing 9 will rise and reset under the elastic force of the elastic part 6 (it can be seen that before the button housing is pressed by an external force, the elastic part is not compressed and is in a natural state).

[0049] After use, when the cover is fixed to the bottle body again, rotate the outer shell 7, and the fixing part 2 will be screwed to the bottle body. At the same time, as the outer shell rotates, the rotating sleeve 3 will also rotate, so that the bump 51 located in the first section 311 descends along the second section 312, and drives the pressure-resistant part 5, the elastic part 6, the pressing part 4, the piston 1, the button 8 and the button housing 9 to descend together (since the elastic part descends with the pressure-resistant part, the elastic part is not compressed). As the piston 1 descends, the space in the liquid suction cavity 20 decreases and the pressure increases, which will discharge the cosmetics or air in the straw connected to the liquid suction cavity, preparing for the next suction of cosmetics; when the bump 51 moves into the third section 313, the outer shell 7 and the rotating sleeve 3 will form a one-way anti-rotation fit relative to the fixing part 2, so that by continuing to rotate the outer shell, the fixing part can be tightened with the bottle body, realizing the screw connection and sealing fixation of the liquid dispenser and the bottle body (at this time, the pressing part, the piston, the button and the button housing are not subject to a downward external force, so the elastic part remains in the uncompressed state at this time).

[0050] The present application also provides a container, which includes a container body and a cover. The cover is the above-mentioned liquid pick-up and placement device, and the container body is a bottle for storing liquid. The bottle is a prior art and will not be elaborated here. The bottle can be screwed to the fixing member 2 to achieve the connection, fixation and sealing between the container body and the cover.

[0051] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
