[0027] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0028] like Figures 1 to 8 As shown, a cosmetic container with a replaceable inner bottle in this embodiment includes a container body 1, wherein the container body 1 includes an outer shell 12, a packaging inner bottle 13 and a liquid discharge head 14, a second connecting component that can be detachably connected to the liquid discharge head 14 is provided on the top of the packaging inner bottle 13, a sleeve cavity 121 for being sleeved on the outside of the packaging inner bottle 13 is provided in the outer shell 12, an upper assembly port 122 for the second connecting component to pass through is provided on the top of the outer shell 12, and a lower assembly port 123 for the packaging inner bottle 13 to enter and exit is provided at the bottom of the outer shell 12, the sleeve cavity 121 is communicated with the upper assembly port 122 and the lower assembly port 123 respectively, and a positioning component that can position and assemble the packaging inner bottle 13 into the sleeve cavity 121 is also provided between the sleeve cavity 121 and the packaging inner bottle 13.

[0029] Such a design allows the user to replace the inner bottle 13 of the package separately without replacing the outer shell. This design not only helps to reduce plastic waste and conform to the concept of environmental protection, but also allows the user to reuse the outer shell in a more economical way, achieving the concept of saving, reducing emissions and practicing environmental protection.

[0030] Specifically, the inner bottle 13 of the package in this embodiment is provided with a sleeve cavity 121 in the outer shell, and a lower assembly port 123 is provided at the bottom of the outer shell, so that the inner bottle 13 of the package can be easily entered and exited from the sleeve cavity 121 through the lower assembly port 123, and quick replacement is achieved without the use of tools or complicated steps. The user can directly take out the used inner bottle 13 of the package through the lower assembly port 123 and insert a new inner bottle, thereby improving the convenience of use. In addition, the inner bottle 13 of the package is correctly and firmly positioned in the sleeve cavity 121 through the positioning component, so that the inner bottle 13 of the package will not be positionally shifted in the sleeve cavity 121, which is conducive to the inner bottle 13 of the package assembled with the outer shell, and connected to the liquid outlet head 14 through the second connecting component.

[0031] Preferably, the design of the positioning component can realize the positioning and assembly of the inner bottle 13 and the outer shell of the package. The user can directly hold the outer shell to realize the positioning connection between the inner bottle 13 and the liquid outlet head 14 through the second connecting component, thereby improving the assembly efficiency and the correctness of the assembly and improving the user experience.

[0032] like Figures 1 to 8 As shown, the positioning assembly of this embodiment includes an outer wall of the inner bottle 13 and an inner wall of the sleeve cavity 121. The shape of the outer wall of the inner bottle 13 is similar to or the same as the shape of the inner wall of the sleeve cavity 121, and the outer wall of the inner bottle 13 is similar to or abuts against the inner wall of the sleeve cavity 121. This design ensures that the inner bottle 13 can fit tightly in the sleeve cavity 121, thereby achieving accurate positioning and stable assembly.

[0033] Specifically, the outer wall of the inner bottle 13 of the package is close to or against the inner wall of the sleeve cavity 121, which means that there is almost no gap or only a very small gap between the two. This tight fit helps prevent the inner bottle 13 of the package from moving or rotating in the sleeve cavity 121, thereby achieving the positioning and assembly of the inner bottle 13 of the package and the outer shell.

[0034] During the assembly process, the user only needs to insert the inner bottle 13 into the sleeve cavity 121. Due to the high matching of the shapes of the two, the inner bottle 13 will be automatically positioned in the correct position. This design simplifies the assembly steps and improves the assembly efficiency.

[0035] When the inner bottle 13 of the package needs to be replaced or cleaned, the user can easily remove the inner bottle 13 from the sleeve cavity 121 , and due to the tight fit of the positioning assembly, the disassembly process is also simple and quick.

[0036] like Figures 1 to 8 As shown, the cross-sectional shape of the outer wall of the inner bottle 13 of the package in this embodiment is polygonal.

[0037] Specifically, the polygonal cross-sectional shape enables the outer wall of the inner bottle 13 of the package to form a tight fit with the inner wall of the sleeve cavity 121. This design can ensure the accurate position of the inner bottle 13 of the package in the sleeve cavity 121 and prevent it from rotating or moving during use.

[0038] Preferably, the polygonal structure provides more contact points, increasing the contact area between the inner bottle 13 of the package and the sleeve cavity 121, thereby improving the overall stability. The polygonal cross-sectional shape allows the inner bottle 13 of the package to be easily aligned with the sleeve cavity 121 during assembly, simplifying the assembly process. At the same time, it is also relatively easy to disassemble, and the user can easily remove the inner bottle 13 of the package from the sleeve cavity 121 for cleaning or replacement.

[0039] The polygonal cross-sectional shape provides design flexibility. Designers can choose different polygonal shapes such as square, hexagon or other shapes as needed to meet different functional needs and aesthetic requirements.

[0040] Furthermore, polygonal cross-sectional shapes may also be used to enhance the aesthetic appeal of a product and provide a unique identification feature for a brand. This design can make a product stand out in the market and attract the attention of consumers.

[0041] like Figures 1 to 8 As shown, the positioning assembly of this embodiment includes a positioning component, and the positioning component includes a plurality of positioning blocks 15 and corresponding positioning slots 16 , and each of the positioning blocks 15 can be inserted into a corresponding positioning slot 16 .

[0042] During assembly, the user inserts the inner bottle 13 into the sleeve cavity 121, and the positioning blocks 15 are snapped into the corresponding positioning slots 16 one by one. This process ensures the accurate position of the inner bottle 13 in the sleeve cavity 121 to prevent any movement or rotation during use.

[0043] When the inner bottle 13 needs to be replaced or cleaned, the user can perform the reverse operation to remove the inner bottle 13 from the sleeve cavity 121 . Due to the tight fit between the positioning block 15 and the positioning slot 16 , the disassembly process is also simple and quick.

[0044] Preferably, in this embodiment, the positioning block 15 is arranged at the connection between the inner bottle 13 of the package and the second connecting component, and the positioning slot 16 is arranged at the upper assembly port 122, so that the second connecting component can be accurately positioned after passing through the upper assembly port 122, thereby achieving the effect of dual positioning and assembly, that is, the second connecting component can be accurately positioned and assembled with the upper assembly port 122, and the inner bottle 13 of the package can also be accurately positioned and assembled with the outer shell 12.

[0045] like Figures 1 to 8As shown, the second connection assembly of this embodiment includes a first connection head 131, and a second connection head 141 corresponding to the first connection head 131 is provided at the bottom of the liquid outlet head 14, and the first connection head 131 and the second connection head 141 are also provided with a connecting member.

[0046] Preferably, the connection member may be a thread, a buckle or other mechanical connection method to ensure a stable connection between the first connector 131 and the second connector 141. The design of these connection members needs to take into account easy assembly and disassembly while ensuring sufficient connection strength.

[0047] Preferably, the second connecting head 141 of the present embodiment includes a third connecting head 142 and a connecting groove 143, wherein the connecting groove 143 is arranged on the outer side of the third connecting head 142, the first connecting head 131 can extend into the connecting groove 143, and the third connecting head 142 can extend into the first connecting head 131, and the connecting component includes a sliding groove 132 arranged on the outer side of the first connecting head 131 and recessed inwardly, and a linkage protrusion 144 arranged on the inner side of the connecting groove 143 and protruding outwardly, and the linkage protrusion 144 can slide in the sliding groove 132.

[0048] Specifically, the third connector 142 is designed to extend into the first connector 131 to form an insertion connection, thereby increasing the stability of the connection.

[0049] The connecting groove 143 is an annular groove surrounding the outer side of the third connecting head 142. The design of the connecting groove 143 allows a portion of the first connecting head 131 to extend into it, thereby forming another form of connection. The sliding groove 132 is designed to cooperate with the linkage protrusion 144 on the inner side of the connecting groove 143. This design allows the linkage protrusion 144 to slide in the sliding groove 132, thereby providing guiding and locking functions during assembly and disassembly.

[0050] During assembly, the user aligns the first connector 131 with the second connector 141, inserts the third connector 142 into the first connector 131, and at the same time, a portion of the first connector 131 extends into the connecting groove 143, and then, the sliding linkage protrusion 144 enters the sliding groove 132 to complete the connection locking. During disassembly, the user only needs to reverse the operation to slide the linkage protrusion 144 out of the sliding groove 132 to easily separate the first connector 131 and the second connector 141.

[0051] like Figures 1 to 8 As shown, the shape of the sliding groove 132 of this embodiment is similar to an “L” shape, and the linkage protrusion 144 and the sliding groove 132 are connected in a right-angle rotational manner.

[0052] Specifically, the sliding groove 132 is designed to be in an "L" shape, which means that it has two main parts, a horizontal groove and a vertical groove. This shape design allows the linkage protrusion 144 to be inserted through the vertical groove, and then slide in the horizontal direction through the horizontal groove, and then be locked through the outer side wall of the first connector 131 located at the top vertical part of the horizontal groove, thereby ensuring the stability and safety of the connection.

[0053] The linkage protrusion 144 is designed to be able to cooperate with the sliding groove 132 in right-angle rotation. This design not only simplifies the assembly process, but also improves the reliability of the connection.

[0054] During disassembly, the user only needs to perform the reverse operation to move the linkage protrusion 144 from the horizontal portion of the sliding groove 132 to the vertical portion, and then slide along the vertical direction to easily separate the first connector 131 and the second connector 141 .

[0055] like Figures 1 to 8 As shown, an unlocking mark 145 is provided on the outer side wall of the liquid dispensing head 14 of this embodiment to ensure that the user can correctly load and unload the liquid dispensing head 14 and the inner bottle of the package.

[0056] like Figures 1 to 8 As shown, a sealing gasket 133 is provided between the top of the first connector 131 and the connecting groove 143 of this embodiment. The sealing gasket 133 is designed so that it can fit tightly between the first connector 131 and the connecting groove 143 to form an effective sealing interface.

[0057] The main function of the sealing gasket 133 is to prevent the fluid material from leaking from the connection between the inner bottle of the package and the liquid outlet head. When the first connector 131 is connected to the second connector 141, the sealing gasket 133 is compressed to fill any tiny gap that may exist, ensuring that the fluid material can only flow out and be discharged through the liquid outlet head.

[0058] During assembly, the sealing gasket 133 is placed on the first connector 131 or the connecting groove 143. When the first connector 131 is inserted into the connecting groove 143, the sealing gasket 133 is compressed between the top of the first connector 131 and the connecting groove 143 to form a tight seal. This design ensures that a good sealing effect can be maintained even under high pressure or frequent use.

[0059] like Figures 1 to 8 As shown, the liquid outlet head 14 of this embodiment includes an upper liquid outlet shell 146 and a lower liquid outlet shell 147, which are a detachable connection structure. The liquid outlet head 14 is provided with an assembly portion for assembling the peristaltic pump assembly 2. With such a design, the peristaltic pump assembly 2 can be quickly maintained.

[0060] Preferably, the assembly portion of this embodiment includes an assembly groove 148 and at least two second elastic connecting buckles 149, and the second elastic connecting buckles 149 are arranged on both sides of the assembly groove 148. The peristaltic pump assembly 2 is installed on the assembly groove 148, and the second elastic connecting buckles 149 on both sides are engaged with the outer side of the peristaltic pump assembly 2.

[0061] Specifically, each second elastic connection buckle 149 can adapt to the shape of the peristaltic pump assembly 2 through elastic deformation, and return to its original shape after the assembly is installed in place, thereby providing a stable fixing effect.

[0062] When assembling the peristaltic pump assembly 2, first place the assembly in the assembly groove 148 to ensure that it is in the correct position. Then, push the peristaltic pump assembly 2 into place, and elastically deform the second elastic connecting buckles 149 on both sides so that the second elastic connecting buckles 149 are reset inward and automatically engaged on the outside of the peristaltic pump assembly 2, ensuring that the assembly is firmly fixed in the assembly groove 148.

[0063] Specifically, the second elastic connection buckle 149 is also provided with a guiding inclined surface for the peristaltic pump assembly 2 to be inserted into the assembly groove 148 .

[0064] When the peristaltic pump assembly 2 needs to be maintained or replaced, the user only needs to pry the second elastic connecting buckle 149 outward to elastically deform it, thereby releasing the fixation of the peristaltic pump assembly 2. This design makes the disassembly process simple and quick, and facilitates necessary maintenance work.

[0065] like Figures 1 to 8 As shown, the upper liquid outlet housing 146 and the lower liquid outlet housing 147 of this embodiment have a clamping component, and the clamping component includes a connecting clamping block 17 and a connecting clamping slot 18 . The connecting clamping block 17 can be clamped into the connecting clamping slot 18 .

[0066] Specifically, the connecting block 17 is a protruding portion located on the upper liquid outlet housing 146 or the lower liquid outlet housing 147, and is designed to match the connecting slot 18. The shape and size of the connecting block 17 are precisely designed to ensure that it can be accurately inserted into the connecting slot 18, thereby achieving effective connection between the two parts.

[0067] The connecting card slot 18 is a groove located on the other part (the lower liquid outlet housing 147 or the upper liquid outlet housing 146), which is specially designed to receive the connecting card block 17. The shape and size of the connecting card slot 18 match the connecting card block 17 to ensure that the card block can be firmly inserted into the slot to form a tight connection.

[0068] During assembly, the user aligns the connecting block 17 with the connecting slot 18 and applies appropriate pressure to slide the block into the slot. Once the connecting block 17 is fully inserted into the connecting slot 18, the two parts are tightly connected together through this snap-fit ​​mechanism. This design simplifies the assembly process and improves assembly efficiency.

[0069] When disassembly or maintenance is required, the user only needs to apply force in the opposite direction to disengage the connecting block 17 from the connecting slot 18. This snap-fit ​​design makes the disassembly process simple and quick, and facilitates necessary maintenance work.

[0070] like Figures 1 to 8 As shown, the container body 1 of this embodiment also includes a sealing cover 19, which is detachably connected to the liquid discharge head 14. This is a component covering the liquid discharge head 14, used to protect the liquid discharge head 14 from external contamination and maintain the sealed state inside the container.

[0071] Specifically, the connection between the sealing cover 19 and the liquid discharge head 14 is designed to be detachable, which means that the user can easily open or close the sealing cover 19 to use the liquid discharge head 14. This design usually involves some form of snap, thread or other quick release mechanism, making the installation and removal of the sealing cover 19 simple and quick.

[0072] In a preferred design, the bottom of the sealing cover 19 abuts against the top of the outer shell 12. This design ensures that the sealing cover 19 fits tightly on the liquid outlet head 14, thereby providing a better sealing effect. When the sealing cover 19 is closed, the contact between its bottom and the top of the outer shell 12 forms a sealing interface to prevent air or contaminants from entering the interior of the container.

[0073] During assembly, the user places the sealing cover 19 on the liquid dispensing head 14 and fixes it using a detachable connection mechanism. When using the container body 1, the user can easily open the sealing cover 19, use the liquid dispensing head 14 to dispense liquid, and after use, close the sealing cover 19 to keep the container sealed.

[0074] like Figures 1 to 8 As shown, the outer curvature of the sealing cover 19 of this embodiment is close to or offset to the outer curvature of the outer shell 12, which means that the two present a coordinated appearance visually. This design makes the container body 1 look more unified and professional, enhancing the aesthetics and market appeal of the product.

[0075] Furthermore, when the bottom of the sealing cover 19 abuts against the top of the housing 12, the similar curvature of the two ensures that the sealing cover 19 can fit tightly against the housing 12, reducing possible gaps and voids. This tight fit not only improves the sealing effect, but also enhances the stability of the overall structure.

[0076] And because the curvature of the sealing cover 19 is offset against that of the outer shell 12, when the sealing cover 19 is closed, its outer side forms a continuous sealing interface with the outer side of the outer shell 12. This design effectively prevents air, moisture or other contaminants from entering the interior of the container, thereby maintaining the cleanliness of the interior of the container and the quality of the product.

[0077] During assembly, the arc design of the sealing cover 19 allows it to be easily aligned with the housing 12 and installed in place. During use, the user can intuitively feel the close fit between the sealing cover 19 and the housing 12, thereby having a higher degree of trust in the sealing performance of the product.

[0078] Specifically, a material containing assembly capable of accommodating fluid materials is provided in the inner bottle 13 of the package, and the liquid outlet head 14 is provided with a peristaltic pump assembly 2, a driving assembly 3, a suction assembly 4 and a discharge assembly 5, wherein the suction assembly 4 is located between the peristaltic pump assembly 2 and the material containing assembly, one end of the suction assembly 4 is connected to the input end of the peristaltic pump assembly 2, and the other end extends into the material containing assembly; the discharge assembly 5 is connected to the output end of the peristaltic pump assembly 2, and the driving assembly 3 is transmission-connected to the peristaltic pump assembly 2, and the driving assembly 3 can drive the peristaltic pump assembly 2 to work, so that the peristaltic pump assembly 2 absorbs the fluid material in the material containing assembly through the suction assembly 4, and then discharges the fluid material to the outside through the discharge assembly 5.

[0079] Specifically, by adopting the peristaltic pump assembly 2 as the discharge core, and accurately controlling the rotation speed of the peristaltic pump assembly 2 through the driving assembly 3, when the driving assembly 3 drives the peristaltic pump assembly 2, the peristaltic pump assembly 2 absorbs a certain amount of fluid material from the containing assembly through the suction assembly 4, and then accurately discharges the absorbed fluid material to the outside through the discharge assembly 5. With such a design, the cosmetic container of this embodiment can provide precise discharge dosage control, and the user can adjust the discharge amount as needed to avoid excessive use and waste of cosmetics, while ensuring consistency and effect of each use.

[0080] like Figures 1 to 8 As shown, the peristaltic pump assembly 2 of the present embodiment includes a pump body 21, a pump tube 22, a pump wheel 23 and a roller assembly, wherein the pump wheel 23 is rotatably disposed in the pump body 21, and the roller assembly is disposed on the pump wheel 23, the pump tube 22 is located between the pump body 21 and the pump wheel 23, and is surrounded by the outer side of the roller assembly, the input end of the pump tube 22 is connected to the suction assembly 4, and the output end of the pump tube 22 is connected to the discharge assembly 5; the pump wheel 23 is transmission-connected to the drive assembly 3.

[0081] Specifically, the peristaltic pump assembly 2 in this embodiment is a key part for achieving precise discharging, and its structure includes a pump body 21, a pump tube 22, a pump wheel 23 and a roller assembly. This design utilizes the working principle of the peristaltic pump, that is, the pump tube is squeezed by the rotation of the pump wheel, thereby pushing the fluid material to move in the pump tube.

[0082] Specifically, the pump body 21 is the outer shell of the peristaltic pump assembly 2, and a pump wheel 23 is arranged inside. The pump wheel 23 is rotatable in the pump body 21, and is connected to the driving assembly 3 by transmission, and realizes rotation through the power provided by the driving assembly 3. The roller assembly is installed on the pump wheel 23. The function of the roller assembly is that when the pump wheel rotates, the roller assembly squeezes the pump tube 22. The pump tube 22 is a flexible pipe, which is located between the pump body 21 and the pump wheel 23 and is arranged around the outside of the roller assembly. In addition, the input end of the pump tube 22 is connected to the suction assembly 4 for sucking the fluid material in the material holding assembly, and the output end of the pump tube 22 is connected to the discharge assembly 5 to accurately transport the fluid material to the discharge assembly 5 for user use.

[0083] When the driving assembly 3 drives the pump wheel 23 to rotate, the roller assembly squeezes the pump tube 22, so that the fluid material in the pump tube 22 is pushed forward. Due to the flexibility of the pump tube 22, the pump tube 22 will return to its original state after each squeezing of the roller assembly, and negative pressure will be generated, and the fluid material in the material holding assembly will be sucked through the material suction assembly 4, thereby forming a continuous fluid delivery process. This design can ensure that the fluid material is delivered to the discharge assembly 5 in an accurate amount, achieving accurate discharge.

[0084] Through the design of the peristaltic pump assembly 2, the cosmetic container of this embodiment can provide highly precise discharge control, and the user can adjust the discharge amount as needed to ensure consistency and effect each time of use while reducing waste of cosmetics. In addition, the peristaltic pump assembly 2 has a compact structure and can be easily integrated into the cosmetic container, providing the user with a convenient use experience.

[0085] like Figures 1 to 8 As shown, the roller assembly of this embodiment includes at least two rollers 24 , and the plurality of rollers 24 are arranged at equal intervals on the pump wheel 23 .

[0086] Specifically, the roller assembly in this embodiment is a key part of the peristaltic pump assembly 2, which directly affects the extrusion effect of the pump tube 22 and the delivery accuracy of the fluid material. The roller assembly includes at least two rollers 24, which are equidistantly spaced on the pump wheel 23. This design ensures that the pump tube 22 can be evenly and continuously squeezed by the roller 24 when the pump wheel 23 rotates.

[0087] Specifically, each roller 24 is close to the pump tube 22. When the pump wheel 23 rotates, the roller 24 moves accordingly to squeeze the pump tube 22. Since the rollers 24 are arranged at equal intervals, the pump tube 22 will be evenly squeezed when each roller 24 passes through, which helps to maintain a stable flow of fluid material in the pump tube 22. There is a certain gap between each roller 24. After each roller 24 is squeezed, the pump tube 22 will return to its original state and generate negative pressure, sucking the fluid material in the material holding component through the suction component 4, thereby forming a continuous fluid delivery process.

[0088] The design of the roller assembly not only improves the conveying efficiency of the fluid material, but also ensures the accuracy of the discharge. By precisely controlling the rotation speed of the pump wheel 23 and the number and spacing of the rollers 24, the strength and frequency of each squeezing of the pump tube 22 can be adjusted, thereby achieving precise control of the discharge amount.

[0089] In addition, the design of the roller assembly also takes into account durability and reliability. The roller 24 is usually made of wear-resistant material to withstand long-term use and repeated squeezing of the pump tube 22. At the same time, the structural design of the roller assembly is also easy to maintain and replace, ensuring the long-term stable operation of the cosmetic container.

[0090] Through the design of this roller assembly, the cosmetic container of this embodiment can provide highly precise discharge control, meeting the user's requirements for accuracy and convenience in using cosmetics.

[0091] like Figures 1 to 8 As shown, a limiting component capable of limiting the pump wheel 23 from rotating in the correct discharging direction is provided between the pump wheel 23 and the pump body 21 of this embodiment.

[0092] The limiting component in this embodiment is an important part to ensure the normal operation of the peristaltic pump component 2. It is designed to limit the rotation direction of the pump wheel 23 to ensure that the pump wheel 23 can only rotate in the correct discharge direction. This design prevents the pump wheel 23 from rotating in the wrong direction, thereby ensuring that the fluid material can be transported from the suction component 4 to the discharge component 5 in a predetermined manner.

[0093] The limiting assembly usually includes some mechanical structures, such as a check device or a one-way bearing, which allows the pump wheel 23 to rotate freely in one direction but is restricted in the opposite direction. In this way, even under the action of external force, the pump wheel 23 will not rotate in the opposite direction, ensuring the one-way flow of the fluid material.

[0094] By limiting the rotation direction of the pump wheel 23, the limiting assembly ensures the stability and reliability of the peristaltic pump assembly 2. This design not only improves the operational safety of the cosmetic container, but also reduces the risk of fluid material leakage or delivery errors that may be caused by reverse rotation of the pump wheel 23.

[0095] like Figures 1 to 8 As shown, the limiting component of this embodiment includes a plurality of engaging teeth 231 provided on the pump wheel 23 and at least one elastic limiting tooth 211 provided in the pump body 21. The plurality of engaging teeth 231 are arranged in a circular array on the pump wheel 23. When the pump wheel 23 rotates in the correct discharging direction under the action of the driving component 3, the elastic limiting tooth 211 can move toward the next engaging tooth 231 along the tooth surface of one engaging tooth 231 and can engage with the next engaging tooth 231 under the action of its elasticity. This design ensures that the pump wheel 23 can only rotate in the correct discharging direction under the drive of the driving component 3, thereby realizing precise control of the rotation direction of the pump wheel 23, thereby ensuring the unidirectional flow and precise delivery of the fluid material.

[0096] Specifically, the biting teeth 231 are multiple tooth-like structures provided on the pump impeller 23, which are arranged in a circular array on the pump impeller 23. The design of these biting teeth 231 enables them to interact with the elastic limiting teeth 211 in the pump body 21. The elastic limiting teeth 211 are a tooth-like structure with elasticity, which can engage with the biting teeth 231 when the pump impeller 23 rotates.

[0097] When the pump wheel 23 rotates in the correct discharging direction under the action of the driving component 3, the elastic limiting tooth 211 will slide along the tooth surface of the engaging tooth 231. During the sliding process, the roller 24 continues to squeeze the pump tube 22 and can engage with the next engaging tooth 231 under its elastic action. After engagement, the roller 24 no longer squeezes the pump tube 22, thereby completing a discharging process.

[0098] When the pump wheel 23 rotates in the reverse direction (i.e., in the wrong direction), due to the engagement of the elastic limiting tooth 211 with the current engaging tooth 231, the free end of the elastic limiting tooth 211 will abut against the side wall of the previous engaging tooth 231, making it impossible for the pump wheel 23 to rotate in the reverse direction. This engagement ensures the unidirectional rotation of the pump wheel 23 and prevents the pump wheel 23 from rotating in the wrong direction.

[0099] The design of this limiting component not only improves the working efficiency of the peristaltic pump component 2, but also enhances the reliability and durability of the system. By precisely controlling the rotation direction of the pump wheel 23, the limiting component ensures that the fluid material can be transported from the suction component 4 to the discharge component 5 in a predetermined manner, avoiding backflow or leakage of the fluid material.

[0100] Furthermore, since the elastic limiting tooth 211 is elastic, when the elastic limiting tooth 211 slides along the tooth surface of the biting tooth 231 and engages with the next biting tooth 231, after the elastic limiting tooth 211 moves to the top of the next biting tooth 231, it will be stuck in the corresponding biting tooth 231 due to its elastic deformation and engage with it. During this process, a sound will be emitted, such as a snap, to prompt the user that the elastic limiting tooth 211 has engaged with the next biting tooth 231, that is, the peristaltic pump assembly 2 has output the material once. With such a design, the user can judge how many times the peristaltic pump assembly 2 has output the material according to the number of sounds, thereby accurately controlling the discharge amount of the material.

[0101] Preferably, the drive assembly 3 of the present embodiment includes a manual knob, and the pump wheel 23 is provided with a connecting shaft 232 connected to the manual knob. The drive assembly 3 uses the manual knob as a driving source. This is a simple and effective design, which is particularly suitable for occasions requiring manual control. The setting of the manual knob allows the user to directly drive the pump wheel 23 by rotating the knob, thereby controlling the delivery of the fluid material, and the vibration after the elastic limit tooth 211 and the bite tooth 231 are engaged can be transmitted to the manual knob, and a feedback signal is given to the user that the elastic limit tooth 211 and the bite tooth 231 have been engaged. Through the two signals of sound and physical vibration, the user is ensured to understand the engagement state and engagement frequency of the elastic limit tooth 211 and the bite tooth 231, and the occurrence or non-occurrence of these two signals can also be used to judge whether the working state of the elastic limit tooth 211 and the bite tooth 231 is good and whether maintenance is required.

[0102] Preferably, the connecting shaft 232 is the key connecting component between the pump wheel 23 and the manual knob, one end of which is connected to the manual knob and the other end is fixed to the pump wheel 23. When the user rotates the manual knob, the connecting shaft 232 transmits the rotational torque to the pump wheel 23, causing the pump wheel 23 to rotate in the correct discharging direction.

[0103] This design ensures that the rotation direction of the pump wheel 23 is consistent with the rotation direction of the manual knob, thereby ensuring the unidirectional flow and precise delivery of the fluid material.

[0104] As a part of the driving assembly 3, the design of the manual knob also needs to take into account the convenience and comfort of user operation. The size, shape and rotational resistance of the knob should be designed according to ergonomic principles to ensure that the user can easily and accurately control the rotation of the pump wheel 23. The size of the manual knob in this embodiment is suitable for the user to operate with one hand. In other embodiments, the user can also use both hands to rotate the manual knob. The appropriate design can be selected according to actual needs.

[0105] Through this careful design, the cosmetic container of this embodiment can provide highly precise and reliable discharge control. The synergistic effect of the manual knob and the connecting shaft 232 not only enhances the functionality of the peristaltic pump system, but also improves the reliability and operational safety of the system. This innovative design provides users with a more efficient and safe cosmetic use experience, and also provides new ideas for the design and manufacture of cosmetic containers.

[0106] Moreover, by adopting such a design, compared with a peristaltic pump structure driven by a motor, the manually driven peristaltic pump structure can reduce the volume of the cosmetic container as much as possible, making the structure of the cosmetic container more compact.

[0107] In other embodiments, the driving component 3 can also select structures such as a push button or a sliding rod, and a suitable design can be selected according to actual needs.

[0108] Preferably, the manual knob is also provided with marking symbols, and the marking symbols mark the correct rotation direction and the wrong rotation direction to ensure that the user can correctly rotate the manual knob to control the correct discharging direction of the cosmetics.

[0109] like Figures 1 to 8 As shown, the pump body 21 of this embodiment is provided with an avoidance hole 212, and the avoidance hole 212 is arranged corresponding to the elastic limiting tooth 211, which can provide a deformation space for the elastic limiting tooth 211. This design ensures that the elastic limiting tooth 211 can freely perform elastic deformation during the rotation of the pump wheel 23, thereby effectively engaging with or separating from the engaging tooth 231.

[0110] Specifically, the avoidance hole 212 is arranged corresponding to the elastic limiting tooth 211, which means that the position and size of the avoidance hole 212 are designed according to the size and movement trajectory of the elastic limiting tooth 211. When the pump wheel 23 rotates in the correct discharging direction under the action of the driving component 3, the elastic limiting tooth 211 will slide along the tooth surface of the biting tooth 231 and enter the avoidance hole 212 for deformation when necessary.

[0111] The existence of the avoidance hole 212 enables the elastic limiting tooth 211 to undergo necessary deformation without being hindered by other parts of the pump body 21. This deformation is the key to the engagement between the elastic limiting tooth 211 and the engaging tooth 231, which ensures the unidirectional rotation of the pump wheel 23 and prevents the pump wheel 23 from rotating in the wrong direction.

[0112] In addition, the design of the avoidance hole 212 also takes into account the overall structural strength and stability of the pump body 21. Although the avoidance hole 212 provides deformation space for the elastic limiting tooth 211, its design also ensures the structural integrity and durability of the pump body 21 in other aspects.

[0113] Preferably, the avoidance hole 212 of this embodiment is a through hole on the pump body 21, which can provide the largest deformation space possible, and can provide a transmission path for the sound generated during the engagement process of the elastic limiting tooth 211 and the engaging tooth 231, ensuring that the sound can be heard by the user.

[0114] like Figures 1 to 8 As shown, the pump body 21 of this embodiment includes an upper pump shell 213 and a lower pump shell 214, and a first connecting component is provided between the upper pump shell 213 and the lower pump shell 214 to enable the two to be detachably connected. This split design is convenient for assembly and maintenance. The connection between the upper pump shell 213 and the lower pump shell 214 adopts a detachable first connecting component. This design makes the assembly and disassembly of the pump body 21 easier and faster.

[0115] Preferably, the first connecting assembly includes at least two first elastic connecting buckles 215, which are located at corresponding positions of the upper pump shell 213 and the lower pump shell 214. When the upper pump shell 213 and the lower pump shell 214 are aligned and close to each other, the first elastic connecting buckles 215 will automatically clamp the other shell to achieve a tight connection between the two. This connection method is not only firm but also easy to operate. The user can complete the assembly or disassembly of the pump body without using any tools.

[0116] The elastic buckle is designed to have sufficient elasticity and strength to ensure that the pump body 21 will not accidentally loosen during operation.

[0117] Preferably, the first connection assembly for realizing the detachable connection between the upper pump housing 213 and the lower pump housing 214 can adopt a variety of structural designs to adapt to different application requirements and design preferences. The following are some common detachable connection structures:

[0118] Threaded connection: The upper pump casing and the lower pump casing can be connected by the cooperation of internal and external threads. This design requires rotating the pump casing to achieve connection or separation, and usually requires a small rotational force.

[0119] Snap-on connection: In addition to the first elastic connection snap-on 215, other types of snap-on designs may also be used, such as a press-on snap-on or a rotational snap-on.

[0120] Magnetic connection: By installing magnets on the contact surface of the pump housing, a magnetic adsorption connection between the pump housings can be achieved.

[0121] Pin connection: Use a pin or dowel to secure the two parts of the pump casing.

[0122] Quick Release Clamps: Use quick release clamps or clips to secure the pump housing.

[0123] Buckle connection: Similar to the buckles on clothing, the pump housing is connected by the combination of buckles and buttonholes.

[0124] Slide-lock mechanism: Locks or unlocks the pump housing by sliding the parts.

[0125] You can choose the appropriate design according to actual needs.

[0126] like Figures 1 to 8 As shown, the discharge assembly 5 of this embodiment includes a discharge cutout 51, which remains closed in a default state, thereby preventing accidental leakage of cosmetics or other fluid materials and air and pollutants from entering the housing through the discharge cutout.

[0127] Furthermore, designing the discharge portion as a cutout can simplify the switch mechanism because no complicated valves or nozzles are required, thereby reducing manufacturing costs and failure rates.

[0128] When the user rotates the manual knob, the pump wheel 23 is driven to rotate, and the roller 24 moves accordingly, squeezing the pump tube 22. The fluid material inside the pump tube 22 is forced to flow to the discharge incision 51, and the pressure of the fluid material forces the discharge incision to open, and the fluid material is discharged through the discharge incision 51. After squeezing, the pump tube 22 returns to its original state, and the discharge incision automatically closes due to the reduction of internal pressure, and negative pressure is generated in the pump tube 22. The fluid material in the material holding component is sucked through the suction component 4 for the next use. The discharge incision 51 can remain in a normally closed state without turning the manual knob, ensuring that the fluid material will not come into contact with the air when not in use, thereby maintaining its stability and quality.

[0129] Preferably, the discharge assembly 5 of this embodiment also includes an output nozzle 52 connected to the output end of the pump tube 22, and the discharge cutout 51 is arranged at the top of the output nozzle 52, and the output nozzle 52 is detachably connected to the liquid discharge head. A detachable connection design is adopted between the output nozzle 52 and the liquid discharge head, which means that the user can easily install or remove the output nozzle as needed. This design is not only convenient for cleaning and maintenance, but also allows the user to replace output nozzles of different styles or functions according to personal preferences.

[0130] Preferably, the discharge cutout 51 is located at the top of the discharge nozzle 52. Such a design ensures that the cosmetics can flow out directly from the cutout, reduces the fluid path, and thus improves the efficiency and accuracy of the discharge.

[0131] like Figures 1 to 8 As shown, the material containing assembly of this embodiment includes a material containing cavity 11 disposed in the inner bottle of the package and a soft material bag disposed in the material containing cavity 11 .

[0132] Specifically, the soft material bag is usually a flexible, squeezable packaging material, which can store fluid materials inside. During the suction process of the peristaltic pump assembly 2, the soft material bag is continuously contracted and squeezed to force the fluid material inside it to move toward the pump tube 22, and when the peristaltic pump assembly stops working, the soft material bag will not expand, and will continue to maintain the contracted state, continuously forcing the fluid material to prepare for the next discharge action. In addition, because the soft material bag can completely collapse when the material is used, the amount of remaining fluid material can be minimized to reduce waste.

[0133] Preferably, the suction assembly 4 includes a suction nozzle connected to the pump tube 22, and the suction nozzle extends into the soft material bag.

[0134] Preferably, in some other embodiments, the material containing assembly may only include the material containing chamber 11, and the material suction nozzle extends into the material containing chamber 11 and extends to the bottom of the material containing chamber 11 to completely absorb the fluid material in the material containing chamber 11 as much as possible.

[0135] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
