Description

Technical Field

[0001] The present invention relates to the technical field of cosmetic containers, and in particular to a replaceable inner cup type cosmetic container. Background Art

[0002] As topics related to environmental protection and sustainable development are gaining more and more attention, the concept of sustainable development has also penetrated into the cosmetics field. Many domestic brands have launched environmentally friendly packaging and refills, actively moving towards sustainable development. The emergence of refills not only saves a lot of material resources, but also brings consumers certain price discounts due to its greener and lighter characteristics than bottled products.

[0003] For example, a Chinese patent with authorization announcement number CN213849201U and authorization announcement date of August 3, 2021 discloses "A replaceable inner cup-type facial cream container", which includes an outer bottle body, a bottle cap, and a replaceable inner cup arranged in the outer bottle body. After installation, the inner cup can be screwed and fixed to the outer bottle body.

[0004] During the installation of the inner cup of the patent, an annular ring at the top edge of the inner cup is arranged on the circumference of the outer bottle body (located above the tightening external thread), and the circumference of the upper end of the inner cup is in contact with the inner wall of the outer bottle body, thereby achieving positioning of the installation of the inner cup. However, during the installation process, the contact area between the inner cup and the outer bottle body (located above the tightening external thread) is large, and the inner cup and the outer bottle body need to be rotated for tightening and fixing, resulting in a large friction force on the inner cup during the installation process, thereby affecting the smoothness of the inner cup installation process. Summary of the invention

[0005] The object of the present invention is to provide a replaceable inner cup type cosmetic container, which has the function of improving the smoothness of installation.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a replaceable inner cup type cosmetic container, comprising a bottle body with a accommodating cavity, a replacement inner cup replaceably arranged in the accommodating cavity of the bottle body, and a bottle cap threadedly connected to the bottle body, the top of the outer wall of the bottle body is provided with a tightening external thread, the inner wall of the bottle cap is provided with a tightening internal thread matching the tightening external thread, the bottle cap is installed to press the top of the replacement inner cup, the replacement inner cup comprises an inner liner, and a handle cover embedded in the top of the inner liner, the top edge of the inner liner is integrally provided with a first annular ring for resting on the upper surface of the bottle body, and a plurality of handles for placing the inner liner on the circumferential side of the top of the inner liner and the first annular ring are arranged in a circumferential array between the circumferential side of the top of the inner liner and the first annular ring. A positioning strip pressed against the inner wall of the accommodating cavity, two downwardly extending arc-shaped pieces are symmetrically arranged on the first annular ring, and a buckling strip and a buckling protrusion spaced apart from the buckling strip are arranged on the inner wall of the arc-shaped piece; a notch for the arc-shaped piece of the replacement inner cup to be inserted from top to bottom and rotatable is arranged at the tightening external thread of the outer wall of the bottle body, and the notch is provided with a first movable groove for the buckling strip and the buckling protrusion to be inserted from top to bottom, and the notch is provided with a first buckling groove which is communicated with the first movable groove and for the buckling strip and the buckling protrusion to be inserted during the rotation process of the replacement inner cup, and the first buckling groove is provided with a buckling ridge which is embedded between the buckling strip and the buckling protrusion when the replacement inner cup is installed in place.

[0007] By adopting the above technical solution, when installing the replacement inner cup, first align the two arc-shaped pieces of the replacement inner cup with the two notches of the bottle body, and press the replacement inner cup downward into the accommodating cavity of the bottle body. During this process, the buckling strip and the buckling protrusion are embedded in the first movable groove from top to bottom, and multiple positioning strips abut against the inner wall of the accommodating cavity. Then, the replacement inner cup is rotated to make the buckling strip and the buckling protrusion embedded in the second sliding groove. During this process, the buckling convex ridge is embedded between the buckling strip and the buckling protrusion through the deformation of the arc-shaped piece; finally, during the installation of the replacement inner cup, the positioning strip, the buckling piece and the bottle body are locked. The contact area is small and the friction force is small. At the same time, when the snap-fitting ridge is embedded between the snap-fitting strip and the snap-fitting protrusion, the arc-shaped positioning protrusion needs to pass through the snap-fitting ridge during the deformation of the arc-shaped piece. During this process, a sound will be made to feedback the user that the installation is in place, thereby improving the smoothness of the installation of the replacement inner cup; at the same time, the groove for the movement of the arc-shaped piece is set on the tightening external thread. Compared with the design in which the groove is set above the tightening external thread in the comparative document, it will not affect the required depth of the bottle cap design, so as to ensure that the height of the bottle cap and the height of the bottle body are maintained in a suitable proportion.

[0008] The present invention is further configured as follows: two positioning protrusions are provided on the top of the bottle body, and a positioning groove is provided on the lower surface of the first annular ring which is embedded in the positioning protrusion when the replacement inner cup is installed in place, and when the positioning protrusion is not embedded in the positioning groove, the buckling strip and the buckling protrusion can be embedded in the first buckling groove during the rotation of the replacement inner cup through the deformation of the arc-shaped piece.

[0009] By adopting the above technical solution, a positioning protrusion is provided on the top of the bottle body, and a corresponding positioning groove is provided on the lower surface of the first annular ring of the replacement inner cup, so as to further position the installation of the replacement inner cup; at the same time, when the snap-fit ​​strip and the snap-fit ​​protrusion are in the first movable groove, the positioning protrusion can be provided to create a gap between the first annular ring and the upper surface of the bottle body. At this time, the positioning groove and the inner wall of the accommodating cavity are separated to reduce the friction during the removal of the replacement inner cup, thereby facilitating the removal of the replacement inner cup.

[0010] The present invention is further configured as follows: the peripheral side of the inner liner is spaced apart from the inner wall of the accommodating cavity, and the bottom of the inner liner is spaced apart from the bottom of the accommodating cavity.

[0011] By adopting the above technical solution, after the inner liner that replaces the inner cup is installed, the surrounding side of the inner liner is spaced apart from the inner wall of the accommodating cavity, and the bottom of the inner liner is spaced apart from the bottom of the accommodating cavity, so that the space formed between the two has the effect of heat preservation and insulation.

[0012] The present invention is further configured as follows: an annular groove is provided at the connection between the inner wall and the upper surface of the inner container, a second annular ring embedded in the annular groove is integrally provided on the periphery of the handle cover, and an annular protrusion is integrally provided on the periphery of the handle cover which presses against the inner wall of the inner container when the handle cover is installed in place.

[0013] By adopting the above technical scheme, the annular groove of the inner liner and the second annular ring of the handle cover can realize the positioning of the handle cover during installation. The annular protrusion on the peripheral side of the handle cover presses against the inner wall of the inner liner when the handle cover is installed in place, thereby slightly fixing the installed handle cover through friction, thereby preventing the handle cover from falling off directly without the action of external force.

[0014] The present invention is further configured as follows: the bottle cap includes an outer cap, an inner cap bonded inside the outer cap and having a tightening internal thread, and a sealing gasket embedded inside the inner cap and pressed against a replacement inner cup during the installation of the bottle cap; a plurality of anti-slip strips are arranged in a circumferential array on the circumferential side of the inner cap and pressed against the inner wall of the outer cap during the process of being embedded in the outer cap, a downwardly recessed glue injection groove is arranged on the upper surface of the inner cap, a glue injection hole connected to the glue injection groove is arranged on the inner cap, a separating ring is arranged in the glue injection groove and abuts against the inner part of the outer cap after the inner cap is installed, the glue injection hole is located in the separating ring, and a fixed glue layer is formed between the inner cap and the outer cap after the glue injection is solidified.

[0015] By adopting the above technical solution, during the process of embedding the inner cover into the outer cover, the anti-slip strips in a circumferential array can be pressed against the inner wall of the outer cover to achieve firm fixation, and the friction resistance of the inner cover will not be too large during the process of embedding the inner cover into the outer cover; and by setting the glue injection groove and the glue injection hole, the outer cover and the inner cover can be bonded and fixed after the glue is injected, and the setting of the separation ring can prevent the glue from overflowing from the connection gap between the inner cover and the outer cover during the injection process.

[0016] The present invention is further configured as follows: an ejection mechanism is provided at the bottom of the accommodating cavity for driving the replacement inner cup to move upward when the snap-fit ​​strip and the snap-fit ​​protrusion are in the first movable groove; a first mounting groove is provided at the bottom of the accommodating cavity, and the ejection mechanism includes an ejection sleeve telescopically arranged in the first mounting groove, and a driving component for driving the ejection sleeve to move upward to drive the replacement inner cup to move upward.

[0017] By adopting the above technical solution, the replacement inner cup can be rotated and fastened by pressing downward. It is convenient to press the replacement inner cup downward and turn the knob. However, when taking out the replacement inner cup, it is convenient to rotate the replacement inner cup, but it is more difficult to take out the replacement inner cup. Therefore, an ejection mechanism is provided to drive the ejection sleeve in the first movable groove to move upward through the driving assembly, thereby facilitating the removal of the replacement inner cup.

[0018] The present invention is further configured as follows: a regular polygonal groove is provided at the top of the ejector sleeve, a regular polygonal portion embedded in the regular polygonal groove is provided at the bottom of the replacement inner cup, the driving assembly includes a mounting plate bonded to the bottom of the first mounting groove, a connecting ring, and a first compression spring fixedly arranged between the connecting rings of the mounting plate, the bottom of the ejector sleeve is rotatably connected to the middle part of the connecting ring, a plurality of second movable grooves extending in a vertical downward direction are provided on the inner wall of the first mounting groove, a second snap-fitting groove which is communicated with the bottom of the second movable groove and extends in a horizontal direction is provided on the inner wall of the first mounting groove, a snap-fitting block is provided on the circumferential side of the ejector sleeve, and in the process of pressing the replacement inner cup downward and rotating to snap-fit, the snap-fitting block moves downward along the second movable groove and snaps along the second snap-fitting groove.

[0019] By adopting the above technical solution, in the process of pressing the replacement inner cup downward and rotating to engage, the engaging block moves downward along the second movable groove and rotates along the second engaging groove to engage, so that the ejection sleeve can be engaged in the second engaging groove of the first mounting groove to limit the position, and no continuous force will be applied to the bottom of the replacement inner cup to avoid deformation of the bottom of the replacement inner cup. At this time, the wall thickness of the replacement inner cup can also be thinner during design to avoid excessive material waste, which is in line with the concept of environmental protection; at the same time, when the engaging strip and the engaging protrusion are in the first movable groove, the engaging block also rotates into the second movable groove. At this time, the elastic force of the first compression spring can drive the ejection sleeve to move upward, thereby driving the replacement inner cup to move upward, so as to facilitate the removal of the replacement inner cup.

[0020] The present invention is further configured as follows: the first mounting groove is square, a second mounting groove which is connected to the first mounting groove and has a "convex"-shaped cross-section is provided at the bottom of the bottle body, the driving assembly includes a knob which is arranged in the second mounting groove and the bottom of which is flush with the bottom of the lower surface of the bottle body, a connecting plate which is telescopically arranged in the first mounting groove, a rotating shaft which is arranged on the knob and passes through the connecting plate, a second compression spring which is arranged at one end of the rotating shaft passing through the connecting plate, an anti-detachment end cover which is arranged at the upper end of the rotating shaft and prevents the second compression spring from falling off, a linkage which is arranged between the connecting plate and the knob and drives the connecting plate to overcome the elastic force of the second compression spring and move upward during the rotation of the knob, and the ejection sleeve is arranged on the connecting plate and drives the replacement inner cup to move upward during the upward movement of the connecting plate.

[0021] By adopting the above technical solution, similarly to the setting of the drive component, no continuous force will be applied to the top of the replacement inner cup when not working, so as to avoid deformation of the bottom of the replacement inner cup; when the replacement inner cup needs to be ejected upward, by turning the knob, the linkage drives the connecting plate to overcome the elastic force of the second compression spring and then move upward, driving the ejection sleeve to drive the replacement inner cup to move upward.

[0022] The present invention is further configured as follows: the linkage member includes a first linkage ring arranged on the upper surface of the knob and surrounding the rotating axis, and a second linkage ring arranged on the lower surface of the connecting plate and surrounding the rotating axis, the upper surface of the first linkage ring is an inclined surface, and the lower surface of the second linkage ring matches the upper surface of the first linkage ring.

[0023] By adopting the above technical solution, the linkage part includes a first linkage ring and a second linkage ring. At this time, when the knob overcomes the elastic force of the second compression spring and rotates one circle, the function of automatic reset of the ejection sleeve after moving upward is realized. While facilitating the ejection of the replacement inner cup, there will be no resistance to the installation of the replacement inner cup.

[0024] The present invention is further configured as follows: a third mounting groove which is communicated with the second mounting groove and has a "convex"-shaped cross-section is provided at the bottom of the bottle body; the driving assembly includes a flexible sac body which is embedded in the third mounting groove and whose lower surface is flush with the lower surface of the bottle body, an air bag which is provided in the first mounting groove and bonded to the ejection sleeve, and an air tube provided between the air bag and the flexible sac body; in the process of pressing the flexible sac body, the air bag is inflated to drive the ejection sleeve to move upward; when the flexible sac body is released, the flexible sac body gradually recovers its deformation.

[0025] By adopting the above technical solution, when the ejection sleeve needs to be driven to move upward, the flexible bladder is pressed, and the airbag is inflated to drive the ejection sleeve to move upward. When the flexible bladder is released, the flexible bladder will gradually restore its deformation. During the installation of a new replacement inner cup, the gas can be returned to the flexible bladder by squeezing the inflated airbag, so that the flexible bladder can quickly restore its deformation.

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0029] Embodiment 1: A replaceable inner cup type cosmetic container, such as Figures 1 to 3 As shown, it includes a bottle body 1 with a accommodating cavity 11, a replacement inner cup 2 that can be replaceably arranged in the accommodating cavity 11 of the bottle body 1, and a bottle cap 3 threadedly connected to the bottle body 1. The top of the outer wall of the bottle body 1 is provided with a tightening external thread 12, and the inner wall of the bottle cap 3 is provided with a tightening internal thread 321 matching the tightening external thread 12. After the bottle cap 3 is installed, the top of the replacement inner cup 2 is pressed tightly.

[0030] like Figures 2 to 5As shown, the replacement inner cup 2 includes an inner liner 21 and a handle cover 22 embedded in the top of the inner liner 21. The top edge of the inner liner 21 is integrally provided with a first annular ring 211 for resting on the upper surface of the bottle body 1. A plurality of positioning strips 212 for pressing against the inner wall of the accommodating cavity 11 are arranged in a circular array between the circumferential side of the top of the inner liner 21 and the first annular ring 211. Two arc-shaped pieces 213 extending downward are symmetrically arranged on the first annular ring 211. A buckling strip 214 and a buckling protrusion 215 spaced apart from the buckling strip 214 are arranged on the inner wall of the arc-shaped piece 213. A notch 13 is provided at the tightening external thread 12 on the outer wall of the bottle body 1 for the arc-shaped piece 213 of the replacement inner cup 2 to be inserted from top to bottom and can be rotated. The notch 13 is provided with a first movable groove 131 for the buckling strip 214 and the buckling protrusion 215 to be inserted from top to bottom. The notch 13 is provided with a first buckling groove 132 which is communicated with the first movable groove 131 and for the buckling strip 214 and the buckling protrusion 215 to be inserted during the rotation process of the replacement inner cup 2. The first buckling groove 132 is provided with a buckling ridge 133 which is embedded between the buckling strip 214 and the buckling protrusion 215 when the replacement inner cup 2 is installed in place.

[0031] like Figure 4 and Figure 5 As shown, two positioning protrusions 14 are arranged on the top of the bottle body 1, and a positioning groove 216 is arranged on the lower surface of the first annular ring 211 to be embedded in the positioning protrusion 14 when the replacement inner cup 2 is installed in place. When the positioning protrusion 14 is not embedded in the positioning groove 216, the buckling strip 214 and the buckling protrusion 215 can be embedded in the first buckling groove 132 during the rotation process of the replacement inner cup 2 through the deformation of the arc-shaped piece 213. The peripheral side of the inner liner 21 is spaced from the inner wall of the accommodating cavity 11, and the bottom of the inner liner 21 is spaced from the bottom of the accommodating cavity 11.

[0032] like Figure 5 and Figure 6 As shown, an annular groove 217 is provided at the connection between the inner wall and the upper surface of the inner liner 21, a second annular ring 221 embedded in the annular groove 217 is integrally provided on the peripheral side of the handle cover 22, and an annular protrusion 222 is integrally provided on the peripheral side of the handle cover 22 which presses against the inner wall of the inner liner 21 when the handle cover 22 is installed in place.

[0033] like Figure 3 and Figure 7As shown, the bottle cap 3 includes an outer cover 31, an inner cover 32 bonded inside the outer cover 31 and having a tightening internal thread 321, and a sealing gasket 33 embedded inside the inner cover 32 and pressed against the replacement inner cup 2 during the installation of the bottle cap 3; a plurality of anti-slip strips 322 are arranged in a circumferential array on the circumferential side of the inner cover 32 and pressed against the inner wall of the outer cover 31 during the embedding process of the outer cover 31, a downwardly recessed glue injection groove 323 is arranged on the upper surface of the inner cover 32, a glue injection hole 324 connected to the glue injection groove 323 is arranged on the inner cover 32, a separating ring 325 is arranged in the glue injection groove 323 and abuts against the outer cover 31 after the inner cover 32 is installed, the glue injection hole 324 is located in the separating ring 325, and a fixed glue layer 325 is formed between the inner cover 32 and the outer cover 31 after the glue injection is solidified.

[0034] Implementation effect: When installing the replacement inner cup 2, first align the two arc-shaped pieces 213 of the replacement inner cup 2 with the two notches 13 of the bottle body 1, and press the replacement inner cup 2 downward into the accommodating cavity 11 of the bottle body 1. During this process, the buckling strip 214 and the buckling protrusion 215 are embedded in the first movable groove 131 from top to bottom, and the plurality of positioning strips 212 abut against the inner wall of the accommodating cavity 11. Then, the replacement inner cup 2 is rotated to make the buckling strip 214 and the buckling protrusion 215 embedded in the second sliding groove. During this process, the buckling ridge 133 is embedded between the buckling strip 214 and the buckling protrusion 215 through the deformation of the arc-shaped piece 213; finally, during the installation of the replacement inner cup 2, the positioning strip 212 and the buckling protrusion 215 are locked. The contact area between the fitting and the bottle body 1 is small, and the friction force it is subjected to is small. At the same time, when the snap-fitting ridge 133 is embedded between the snap-fitting strip 214 and the snap-fitting protrusion 215, the arc-shaped positioning protrusion 14 can only pass through the snap-fitting ridge 133 during the deformation of the arc-shaped piece 213. During this process, a sound will be made to feedback to the user that the installation is in place, thereby improving the smoothness of the installation of the replacement inner cup 2; at the same time, the groove 13 for the movement of the arc-shaped piece 213 is set on the tightening external thread 12. Compared with the design in which the groove 13 is set above the tightening external thread 12 in the comparative document, it will not affect the required depth of the bottle cap 3 when designing, so as to ensure that the height of the bottle cap 3 and the height of the bottle body 1 are maintained in a suitable proportion.

[0035] By setting a positioning protrusion 14 on the top of the bottle body 1 and setting a corresponding positioning groove 216 on the lower surface of the first annular ring 211 of the replacement inner cup 2, the installation of the replacement inner cup 2 is further positioned; at the same time, when the buckle strip 214 and the buckle protrusion 215 are in the first movable groove 131, the positioning protrusion 14 can make a gap between the first annular ring 211 and the upper surface of the bottle body, and the positioning groove and the inner wall of the accommodating cavity 11 are separated to reduce the friction during the removal of the replacement inner cup 2, which has the effect of facilitating the removal of the replacement inner cup 2. After the inner liner 21 of the replacement inner cup 2 is installed, the surrounding side of the inner liner 21 is spaced from the inner wall of the accommodating cavity 11, and the bottom of the inner liner 21 is spaced from the bottom of the accommodating cavity 11, so that the space formed between the two has the effect of heat preservation and heat insulation. The annular groove 217 of the inner liner 21 and the second annular ring 221 of the handle cover 22 can realize the positioning of the installation of the handle cover 22. The annular protrusion 222 on the side of the handle cover 22 presses against the inner wall of the inner liner 21 when the handle cover 22 is installed in place, so that the installed handle cover 22 is slightly fixed by friction, and the handle cover 22 is prevented from falling off directly without external force. In the process of the inner cover 32 being embedded in the outer cover 31, the anti-slip strips 322 of the circumferential array are pressed against the inner wall of the outer cover 31 to achieve a firm press and fixation, and the friction resistance of the inner cover 32 in the process of being embedded in the outer cover 31 will not be too large; and by setting the glue injection groove 323 and the glue injection hole 324, the outer cover 31 and the inner cover 32 can be bonded and fixed after the glue is injected, and the separation ring 325 can be set to prevent the glue from overflowing from the connection gap between the inner cover 32 and the outer cover 31 during the injection process.

[0036] Embodiment 2: A replaceable inner cup type cosmetic container, based on Embodiment 1, with Figures 8 to 10 As shown, the difference from Example 1 lies in that: an ejection mechanism is provided at the bottom of the accommodating chamber 11 for driving the replacement inner cup 2 to move upward when the snap-fit ​​strip 214 and the snap-fit ​​protrusion 215 are in the first movable groove 131; a first mounting groove 15 is provided at the bottom of the accommodating chamber 11, and the ejection mechanism includes an ejection sleeve 41 telescopically arranged in the first mounting groove 15, and a driving component 42 for driving the ejection sleeve 41 to move upward to drive the replacement inner cup 2 to move upward.

[0037] Based on Example 1, Figures 8 to 10As shown, a regular polygonal groove 411 is provided on the top of the ejection sleeve 41, and a regular polygonal portion 217 embedded in the regular polygonal groove 411 is provided on the bottom of the replacement inner cup 2. The driving assembly 42 includes a mounting plate 421 bonded to the bottom of the first mounting groove 15, a connecting ring 422, and a first compression spring 423 fixedly arranged between the connecting ring 422 of the mounting plate 421. The bottom of the ejection sleeve 41 is rotatably connected to the middle of the connecting ring 422. A plurality of second movable grooves 151 extending in a vertical downward direction are provided on the inner wall of the first mounting groove 15. A second locking groove 152 communicating with the bottom of the second movable groove 151 and extending in a horizontal direction is provided on the inner wall of the first mounting groove 15. A locking block 412 is provided on the circumferential side of the ejection sleeve 41. In the process of replacing the inner cup 2 by pressing downward and rotating to lock, the locking block 412 moves downward along the second movable groove 151 and locks after rotating along the second locking groove 152.

[0038] Implementation effect: In the process of pressing down and rotating the replacement inner cup 2 to engage, the engaging block 412 moves downward along the second movable groove 151 and rotates along the second engaging groove 152 to engage, so that the ejection sleeve 41 can be engaged in the second engaging groove 152 of the first mounting groove 15 for limiting, and will not apply continuous force to the bottom of the replacement inner cup 2 to avoid deformation of the bottom of the replacement inner cup 2. At this time, the wall thickness of the replacement inner cup 2 can also be thinner during design to avoid excessive material waste, which is in line with the concept of environmental protection; at the same time, when the engaging strip 214 and the engaging protrusion 215 are in the first movable groove 131, the engaging block 412 also rotates into the second movable groove 151. At this time, the elastic force of the first compression spring 423 can drive the ejection sleeve 41 to move upward, thereby driving the replacement inner cup 2 to move upward, so as to facilitate the removal of the replacement inner cup 2.

[0039] Embodiment 3: A replaceable inner cup type cosmetic container, based on Embodiment 1, with Figure 11 to Figure 13 As shown, the difference from Example 1 lies in that: an ejection mechanism is provided at the bottom of the accommodating chamber 11 for driving the replacement inner cup 2 to move upward when the snap-fit ​​strip 214 and the snap-fit ​​protrusion 215 are in the first movable groove 131; a first mounting groove 15 is provided at the bottom of the accommodating chamber 11, and the ejection mechanism includes an ejection sleeve 41 telescopically arranged in the first mounting groove 15, and a driving component 42 for driving the ejection sleeve 41 to move upward to drive the replacement inner cup 2 to move upward.

[0040] Based on Example 1, Figure 11 to Figure 13As shown, the first mounting groove 15 is square, and a second mounting groove 16 communicating with the first mounting groove 15 and having a "convex"-shaped cross-section is provided at the bottom of the bottle body 1. The driving assembly 42 includes a knob 424 arranged in the second mounting groove 16 and having a bottom flush with the bottom of the lower surface of the bottle body 1, a connecting plate 425 telescopically arranged in the first mounting groove 15, a rotating shaft 426 arranged on the knob 424 and passing through the connecting plate 425, a second compression spring 427 arranged at one end of the rotating shaft 426 passing through the connecting plate 425, an anti-detachment end cover 428 arranged at the upper end of the rotating shaft 426 and preventing the second compression spring 427 from falling off, and a linkage member 429 arranged between the connecting plate 425 and the knob 424 and driving the connecting plate 425 to move upward after overcoming the elastic force of the second compression spring 427 during the rotation of the knob 424. The ejection sleeve 41 is fixedly arranged on the connecting plate 425 by a screw (not shown in the figure) and drives the replacement inner cup 2 to move upward during the upward movement of the connecting plate 425. The linkage member 429 includes a first linkage ring 4291 arranged on the upper surface of the knob 424 and surrounding the rotating shaft 426, and a second linkage ring 4292 arranged on the lower surface of the connecting plate 425 and surrounding the rotating shaft 426. The upper surface of the first linkage ring 4291 is an inclined surface, and the lower surface of the second linkage ring 4292 matches the upper surface of the first linkage ring 4291.

[0041] Implementation effect: The setting of the driving assembly 42 will not apply continuous force to the top of the replacement inner cup 2 when not working, so as to avoid deformation of the bottom of the replacement inner cup 2; when the replacement inner cup 2 needs to be ejected upward, by turning the knob 424, the linkage member 429 drives the connecting plate 425 to overcome the elastic force of the second compression spring 427 and then move upward, so that the ejection sleeve 41 drives the replacement inner cup 2 to move upward. The linkage member 429 includes a first linkage ring 4291 and a second linkage ring 4292. At this time, when the knob 424 overcomes the elastic force of the second compression spring 427 and rotates one circle, the ejection sleeve 41 automatically resets after moving upward, and while facilitating the ejection of the replacement inner cup 2, no resistance is generated to the installation of the replacement inner cup 2.

[0042] Embodiment 4: A replaceable inner cup type cosmetic container, based on Embodiment 1, with Fig.14 As shown, the difference from Example 1 lies in that: an ejection mechanism is provided at the bottom of the accommodating chamber 11 for driving the replacement inner cup 2 to move upward when the snap-fit ​​strip 214 and the snap-fit ​​protrusion 215 are in the first movable groove 131; a first mounting groove 15 is provided at the bottom of the accommodating chamber 11, and the ejection mechanism includes an ejection sleeve 41 telescopically arranged in the first mounting groove 15, and a driving component 42 for driving the ejection sleeve 41 to move upward to drive the replacement inner cup 2 to move upward.

[0043] Based on Example 1, Fig.14As shown, a third mounting groove 17 which is in communication with the second mounting groove 16 and has a "convex"-shaped cross-section is provided at the bottom of the bottle body 1, and the driving assembly 42 includes a flexible sac 4210 which is embedded in the third mounting groove 17 and whose lower surface is flush with the lower surface of the bottle body 1, an airbag 4211 which is provided in the first mounting groove 15 and bonded to the ejection sleeve 41, and an air tube 4212 which is provided between the airbag 4211 and the flexible sac 4210. In the process of pressing the flexible sac 4210, the airbag 4211 is inflated to drive the ejection sleeve 41 to move upward, and when the flexible sac 4210 is released, the flexible sac 4210 gradually recovers its deformation.

[0044] Implementation effect: When it is necessary to drive the ejection sleeve 41 to move upward, the flexible bladder 4210 is pressed, and the airbag 4211 is inflated to drive the ejection sleeve 41 to move upward. When the flexible bladder 4210 is released, the flexible bladder 4210 will gradually restore its deformation. During the installation of the new replacement inner cup 2, the gas can be returned to the flexible bladder 4210 by squeezing the inflated airbag 4211, so that the flexible bladder 4210 can quickly restore its deformation.
