Description

Technical Field

[0001] This disclosure relates to the field of skincare technology, specifically to a bottle for preserving lotion. Background Technology

[0002] As people's living standards improve, consumers are placing higher demands on the quality and efficacy of skincare products. Skincare products, such as lotions, creams, and serums, typically contain a large amount of water, organic ingredients, and easily oxidized active substances. During production and use, they are highly susceptible to external environmental influences, such as air, moisture, light, and microorganisms, leading to degradation, spoilage, or bacterial growth of active ingredients, affecting the product's safety and efficacy. Currently, preservatives are commonly added to extend shelf life, but these can cause skin irritation or allergic reactions, failing to meet current consumer demands for "gentle and safe" skincare. Furthermore, while skincare products are often packaged in sealed containers, these containers cannot effectively prevent the entry of air and contaminants after opening, resulting in poor preservation after opening. Utility Model Content

The terms “connected” or “linked” and similar terms are not limited to physical or mechanical connections, nor are they limited to direct or indirect connections.

[0021] To address the aforementioned technical problems, an exemplary embodiment of this disclosure provides a milk preservation bottle, such as... Figure 1 As shown, the device may include: a bottle body 110, a cap 120, a needle 130, and a dispensing assembly. The milk preservation bottle can be in a storage state or a usage state. The storage state refers to the factory-shipped state of the milk preservation bottle. When the bottle is in storage, meaning it has not been used, the user cannot obtain milk from it. In this state, the milk is isolated from the outside environment by the bottle, providing good sealing and preservation performance. When the bottle is in use, the user can obtain milk from it. The bottle body 110, cap 120, and their mating structure ensure that the milk inside the bottle body 110 is sealed by the cap 120, preventing contact with the outside environment and providing good preservation performance. While preserving freshness, when the user uses the bottle in its usage state, the milk can flow out from the dispensing assembly to meet the user's needs.

[0022] The bottle body 110 has an internal space for containing emulsion. A dispensing section 111 is formed at the bottom of the bottle body 110, and the bottom surface of the dispensing section 111 is covered with a sealing film 115 to isolate the emulsion inside the bottle body 110 from the outside environment. The bottle body 110 may be cylindrical and hollow, with an internal space for containing emulsion. The dispensing section 111 at the bottom of the bottle body 110 has a dispensing port at its bottom end, allowing the emulsion in the bottle body 110 to flow outward through the dispensing section 111. The bottom surface of the dispensing section 111 may be covered with a sealing film 115, which seals the dispensing port, thus ensuring a high degree of airtightness of the bottle body 110 when the emulsion is in storage. The emulsion in bottle 110 can avoid contact with external air, water and impurities during storage, so that the emulsion stored in bottle 110 has a good sealing effect during storage, thereby achieving the preservation of the emulsion in bottle 110.

[0023] A bottle cap 120 is disposed on the lower part of the bottle body 110. The outer periphery of the bottle cap 120 extends upward to form a first cavity 121 for accommodating at least a portion of the bottle body 110, and the outer periphery of the bottle cap 120 extends downward to form a second cavity 122. The first cavity 121, which extends upward from the outer periphery of the bottle cap 120, can accommodate at least a portion of the bottle body 110. The bottle cap 120 can be disposed on the lower part of the bottle body 110 such that the liquid outlet faces the bottle cap 120, thereby sealing the bottle body 110. The second cavity 122, which can be a cylindrical space, can be used to install a liquid dispensing assembly. The first cavity 121 at the top of the bottle cap 120 can also be a columnar cavity, so that the inner wall of the first cavity 121 can fit with the bottle body 110, so that at least the lower part of the bottle body 110 is installed in the first cavity 121.

[0024] Needle 130, such as Figure 1As shown, a needle 130 is installed in the middle of the bottle cap 120, connecting the first cavity 121 and the second cavity 122. The needle 130 extends towards the bottle body 110, with at least a portion of the needle 130 located within the first cavity 121. When the bottle is in storage, the needle 130 is spaced apart from the sealing film 115. When the bottle is in use, the needle 130 passes through the sealing film 115 to deliver the emulsion. The needle 130 can be installed in the center of the bottle cap 120, allowing the first cavity 121 and the second cavity 122 to communicate through the needle 130. The needle 130 can extend towards the bottle body 110, allowing its tip to reach into the first cavity 121. When the bottle is in storage, the needle 130 and the sealing film 115 are spaced apart, ensuring a sealed state for the bottle body 110 and providing good sealing and preservation effects. When the milk preservation bottle is in use, the bottle body 110 can be pressed down, causing the needle 130 to pass through the sealing film 115. The end of the needle 130 facing the second cavity 122 can communicate with the dispensing component, allowing the milk to flow through the needle 130 to the dispensing component, thus discharging the milk from the outside of the milk preservation bottle. When the milk preservation bottle is in use, the milk inside the bottle body 110 can only flow outwards through the needle 130. Since the bottle cap 120 is located at the bottom of the bottle body 110, it further preserves the milk while the bottle is in use, preventing the milk from contacting the outside air and effectively blocking the entry of air and contaminants. This ensures that the milk preservation bottle maintains good preservation effects when used, effectively preventing the oxidation or microbial growth of moisture, organic matter, and active ingredients in the milk when using the milk preservation bottle provided by this disclosure. The use of the preservative-grade lotion bottle provided in this disclosure offers superior preservation, resulting in better stability of the active ingredients, significantly extending the lotion's shelf life, reducing waste, and improving product efficiency. Furthermore, the superior preservation effect of the lotion bottle ensures that its texture, color, and odor remain stable during use, leading to a better user experience.

[0025] Liquid dispensing components, such as Figure 1 As shown, the dispensing assembly, at least partially disposed within the second cavity 122, communicates with the needle 130 for dispensing emulsion. The dispensing assembly can be at least partially disposed within the second cavity 122, such that one end of the dispensing assembly is connected to the side of the needle 130 facing the second cavity 122. Thus, when the emulsion bottle is in use, the bottle body 110 communicates with the dispensing assembly via the needle 130. When the emulsion bottle is in use, the emulsion within the bottle body 110 can flow from the needle 130 to the dispensing assembly, and finally be discharged out of the emulsion bottle along the dispensing assembly, thereby supplying emulsion to the user.

[0026] The fresh-keeping emulsion bottle provided in this disclosure effectively solves the problem that existing emulsions are susceptible to intrusion by air, moisture, and contaminants during storage or use, leading to emulsion deterioration, loss of active ingredients, or microbial growth. When the fresh-keeping emulsion bottle is in storage, the emulsion is sealed inside the bottle body 110 and completely isolated from the outside environment by a sealing film 115, significantly improving the emulsion's freshness preservation performance during transportation and storage, and preventing oxidation or microbial contamination. When the fresh-keeping emulsion bottle is switched to use, a needle 130 punctures the sealing film 115 to establish communication between the bottle body 110 and the dispensing component. The emulsion enters the needle 130 from the bottle body 110, then flows along the needle 130 to the dispensing component, and finally is discharged from the fresh-keeping emulsion bottle. Throughout the process of emulsion discharge, a relatively closed transport path is maintained, preventing direct contact between the emulsion and air, thus achieving a better preservation effect. Furthermore, the bottle body 110 and cap 120 of the fresh-keeping lotion bottle employ a fitted sealing structure, which, while achieving the dispensing function, further enhances the sealing during the lotion dispensing process, effectively preventing the lotion from flowing back and becoming contaminated or oxidized or polluted upon contact with the outside environment. The lotion only flows out as needed when in use, and the lotion can be dispensed and supplied to the user within a sealed structure, significantly reducing the ease with which the lotion in the bottle is susceptible to air, moisture, and contaminants, thus preventing spoilage, loss of active ingredients, or microbial growth. This fresh-keeping lotion bottle provides excellent preservation, significantly extending the shelf life of the lotion, ensuring the stability and effectiveness of its active ingredients, and improving the texture stability, scent consistency, and user experience during use, achieving highly efficient preservation of skincare products during storage and use.

[0027] In some embodiments, when the milk bottle is in storage, the periphery of a first position at the bottom of the bottle body 110 engages with the top of the side wall of the first cavity 121. When the milk bottle is in use, the periphery of a second position at the bottom of the bottle body 110 engages with the top of the side wall of the first cavity 121, wherein the first position is located below the second position. When the milk bottle is in storage, the periphery of the first position at the bottom of the bottle body 110 can engage with the top of the side wall of the first cavity 121, so that the bottom of the bottle body 110 and the needle 130 are spaced apart, and the connection between the bottle body 110 and the cap 120 has a certain stability. In the event of shaking or slight vibration, the connection between the bottle body 110 and the cap 120 remains stable, and the periphery of the first position at the bottom of the bottle body 110 remains engaged with the top of the side wall of the first cavity 121. When the milk bottle is in use, the user can change the connection position between the bottle body 110 and the cap 120 by pressing down on the bottle body 110. In the storage state, the first position of the bottom of the bottle 110 mates with the top of the side wall of the first cavity 121, with the first position located below the second position. When the user presses down on the bottle 110, the height of the portion of the bottle 110 installed inside the first cavity 121 increases, and the second position of the bottom of the bottle 110 mates with the top of the side wall of the first cavity 121. In the use state, the needle 130 can pierce the sealing film 115, allowing the milk bottle to discharge milk for the user. When the milk bottle is in use, the bottle 110 and the cap 120 are tightly fitted, and the bottle 110 is only connected to the needle 130, preventing contact with external air, water, and contaminants, thus providing high sealing and preservation performance. After the milk in the bottle 110 is used up, the bottle 110 can be removed from the cap 120 and replaced with a new bottle 110.

[0028] According to the fresh-keeping milk bottle provided in this embodiment, such as Figure 1 , Figure 2As shown, in the storage state, the liquid outlet at the bottom of the bottle 110 is completely sealed by the sealing film 115, effectively isolating the entry of external air, moisture, and microorganisms, significantly improving the storage stability and preservation performance of the emulsion, and extending the product's shelf life. In the usage state, the user presses or pushes down the bottle 110, causing the needle 130 to pierce the sealing film 115, allowing the emulsion to flow along the needle 130 through a closed path from the bottle 110 to the dispensing component. This allows for on-demand dispensing of the emulsion, ensuring that only the emulsion flowing to the dispensing component is discharged outside the bottle and exposed to the outside environment, preventing the emulsion inside the bottle 110 from contacting the outside environment with the outside each time it is used, further reducing the risk of oxidation or contamination. In both the first and second positions, the bottle 110 can be fixed with the bottle cap 120, ensuring the overall structural stability of the emulsion bottle. In the storage state, the bottle 110 and bottle cap 120 are fixed in the first position, maintaining the sealing film 115 and the needle 130 at intervals, while maintaining overall structural stability. In use, the bottle body 110 and the cap 120 are fixed together in the second position to ensure smooth dispensing and to make the lotion bottle more stable overall. The lotion bottle provided in this embodiment achieves better preservation, preventing the lotion inside the bottle 110 from coming into contact with the outside environment, which could lead to the deactivation or deterioration of active ingredients. This ensures that the texture, color, and odor of the lotion stored in the bottle remain stable throughout its entire usage period, effectively maintaining the functional properties of its active ingredients and enhancing skincare effects.

[0029] In some embodiments, such as Figure 1 , Figure 2As shown, the bottom of the bottle body 110 extends downward to form a liquid outlet 111. The outer diameter of the liquid outlet 111 is smaller than the outer diameter of the upper part of the bottle body 110, resulting in an annular stepped surface 112 at the bottom of the bottle body 110. The bottle cap 120 is recessed in the middle to form a mounting groove 123 for accommodating the liquid outlet 111. When the fresh milk bottle is in use, the liquid outlet 111 is installed in the mounting groove 123. The bottom of the bottle body 110 can extend downward to form a liquid outlet 111 with an outer diameter smaller than that of the upper part of the bottle body 110. The cross-sectional area of ​​the liquid outlet 111 is also smaller than that of the upper part of the bottle body 110, resulting in a bottle body 110 with a structure that is wider at the top and narrower at the bottom, forming an annular stepped surface 112. The middle of the bottle cap 120 can be recessed to form a mounting groove 123. The inner diameter of the mounting groove 123 can match the outer diameter of the liquid outlet 111, allowing the liquid outlet 111 to be installed in the mounting groove 123. The needle 130 can be partially disposed within the mounting groove 123. When the fresh milk bottle is in use, the dispensing part 111 is installed in the mounting groove 123, and the needle 130 can pass through the sealing film 115 on the bottom surface of the dispensing part 111, so that the bottle body 110 is in communication with the needle 130, and the milk can flow out along the needle 130 to the outside of the bottle body 110. When the fresh milk bottle is in storage, the first position periphery of the bottom of the bottle body 110 mates with the top of the side wall of the first cavity 121, and the dispensing part 111 can be located outside the mounting groove 123. The user can press down the bottle body 110 of the fresh milk bottle in its storage state, so that the second peripheral side of the bottom of the bottle body 110 connects with the top of the side wall of the first cavity 121. The dispensing part 111 is pressed down into the mounting groove 123, and the needle 130 pierces the sealing film 115 covering the bottom surface of the dispensing part 111, allowing the milk to flow out of the bottle body 110 along the needle 130, and the fresh milk bottle is in use. The mounting groove 123 restricts the horizontal movement of the dispensing part 111. While restricting the horizontal movement of the bottle body 110 by the side wall of the first cavity 121, the mounting groove 123 further restricts the movement of the dispensing part 111, making the connection between the bottle body 110 and the cap 120 highly secure and stable. When the fresh milk bottle is in use, the bottom plane of the mounting groove 123 can abut against the bottom plane of the liquid outlet 111, thereby further improving the connection and sealing between the bottle body 110 and the cap 120. In use, it can further ensure the sealing of the milk in the fresh milk bottle, prevent the milk from contacting the outside world, and have better preservation performance.

[0030] According to the fresh-keeping emulsion bottle provided in this embodiment, by designing the bottom of the bottle body 110 to have an outer diameter smaller than that of the liquid outlet 111 at the top of the bottle body 110, and by providing a recessed mounting groove 123 in the middle of the bottle cap 120, the connection structure between the bottle body 110 and the bottle cap 120 is not only more compact, but the sealing performance and structural stability of the fresh-keeping emulsion bottle in use are also significantly improved. By setting the annular stepped surface 112 and the matching mounting groove 123, a clear positioning guide can be provided during the process of pressing the bottle body 110 down into the bottle cap 120, ensuring that the liquid outlet 111 and the mounting groove 123 are precisely matched, thereby achieving stable and reliable assembly. The liquid outlet 111 is located at the bottom of the bottle body 110, and the space inside the bottle body 110 for holding the emulsion is generally wider at the top and narrower at the bottom, so that the emulsion can be more concentratedly discharged through the needle 130 during the outflow process, reducing emulsion residue, improving emulsion discharge efficiency, and reducing waste. By limiting the liquid outlet 111 through the mounting groove 123, the liquid outlet 111 can be effectively constrained in both the horizontal and vertical directions, thereby enhancing the anti-shaking ability of the connection between the bottle body 110 and the cap 120 and improving the overall structural resistance and stability. When the freshness-preserving emulsion bottle is in use, the liquid outlet 111 is pressed into the mounting groove 123 and fits tightly against its bottom plane, so that the stepped surface 112 of the bottle body 110 and the side wall of the first cavity 121 are sealed. At the same time, the bottom surface of the liquid outlet 111 and the bottom of the mounting groove 123 are also sealed. During the emulsion dispensing process, air, moisture or impurities can still be effectively prevented from seeping into the bottle body 110 from the gaps in the cap 120, thereby further enhancing the freshness preservation effect of the emulsion during use and ensuring the stability and safety of the active ingredients in the emulsion.

[0031] In some embodiments, such as Figure 2 , Figure 3 As shown, a first annular groove 113 is formed by an inward recess at the bottom of the bottle body 110. A first annular protrusion 1211 and a second annular protrusion 1212 extend inward from the top of the sidewall of the first cavity 121. The second annular protrusion 1212 is located below the first annular protrusion 1211. When the bottle is in storage, the first annular protrusion 1211 is installed in the first annular groove 113, and the top surface of the second annular protrusion 1212 abuts against the stepped surface 112. Figure 2As shown, a first annular groove 113 is formed by an inward recess at the bottom of the bottle body 110. The first annular groove 113 can cooperate with a first annular protrusion 1211 formed by an inward extension of the top of the side wall of the first cavity 121. Through the cooperation of the first annular groove 113 and the first annular protrusion 1211, the bottle body 110 and the bottle cap 120 can be connected to each other at the first position at the bottom of the bottle body 110, at which time the fresh milk bottle can be in a storage state. A second annular protrusion 1212 can be formed by an inward extension of the top of the side wall of the first cavity 121. The second annular protrusion 1212 is spaced apart from the first annular protrusion 1211, so that the second annular protrusion 1212 is located below the first annular protrusion 1211. The stepped surface 112 formed on the upper part of the liquid outlet 111 can abut against the second annular protrusion 1212. The distance in the height direction between the stepped surface 112 formed on the upper part of the liquid outlet 111 and the bottom surface of the first annular groove 113 can be equal to the distance between the first annular protrusion 1211 and the second annular protrusion 1212, so that while the first annular protrusion 1211 is installed in the first annular groove 113, the top surface of the second annular protrusion 1212 abuts against the stepped surface 112, further improving the connection stability between the bottle cap 120 and the bottle body 110.

[0032] According to the fresh milk bottle provided in this embodiment, the mating connection between the first annular groove 113 and the first annular protrusion 1211 enables stable positioning of the bottle body 110 and the cap 120 in the radial direction, preventing the bottle body 110 from rotating or shaking. The abutment between the top surface of the second annular protrusion 1212 and the stepped surface 112 of the bottle body 110 further restricts the sinking or loosening of the bottle body 110 in the axial direction, thus achieving structural positioning and stable fit in both directions simultaneously. The fresh milk bottle provided in this embodiment significantly improves the overall structural strength and sealing effect of the packaging before the bottle is opened, preventing the bottle body 110 from loosening or leaking due to transportation, vibration, or environmental changes, thereby enhancing safety. The fresh milk bottle provided in this embodiment also ensures a reliable sealed connection between the bottle body 110 and the cap 120 during storage. This structure achieves strong airtightness without relying on additional sealing rings or adhesives, preventing air, moisture, or contaminants from entering the bottle 110 during storage, thereby effectively maintaining the stability of the emulsion's composition.

[0033] In some embodiments, such as Figure 2 , Figure 3As shown, a second annular groove 114 is formed by an inward indentation at the second position of the bottom of the bottle body 110. When the bottle is in use, the top surface of the first annular protrusion 1211 abuts against the top wall of the second annular groove 114, and the bottom surface of the second annular protrusion 1212 abuts against the bottom wall of the second annular groove 114. The second position of the bottom of the bottle body 110 can be indented to form the second annular groove 114, and the height of the second annular groove 114 is greater than the height of the first annular groove 113. When the bottle is in use, the bottle body 110 is pressed down until the liquid outlet 111 is installed in the mounting groove 123. At this time, the first annular protrusion 1211 moves outside the first annular groove 113, so that both the first annular protrusion 1211 and the second annular protrusion 1212 are installed in the second annular groove 114. The top surface of the first annular protrusion 1211 can abut against the top wall of the second annular groove 114, and the bottom surface of the second annular protrusion 1212 can abut against the top surface of the second annular protrusion 1212, so that the top wall and bottom wall of the second annular groove 114 abut against the first annular protrusion 1211 and the second annular protrusion 1212 respectively, so that the first annular protrusion 1211 and the second annular protrusion 1212 are engaged in the second annular groove 114, thereby making the installation between the bottle cap 120 and the bottle body 110 highly stable. The materials of the first annular protrusion 1211 and the second annular protrusion 1212 can undergo a certain degree of deformation. This allows the first annular protrusion 1211 and the second annular protrusion 1212 to change their installation position relative to the bottle body 110 when the user presses the bottle body 110 to change the state of the fresh milk bottle. At the same time, it ensures that the first annular protrusion 1211 and the second annular protrusion 1212 maintain the stability of their connection with the bottle body 110 whether the fresh milk bottle is in storage or in use. The bottle remains stable even under disturbances or minor impacts in any direction. The connection between the first annular protrusion 1211, the second annular protrusion 1212, and the bottle body 110 is altered only when the user presses on the bottle body 110, thus changing the state of the milk bottle. Furthermore, the lower part of the outer wall of the bottle body 110, near the side wall of the first cavity 121, can be recessed inward to form an annular platform. This annular platform can abut against the top of the side wall of the first cavity 121 when the milk bottle is in use. Alternatively, when the milk bottle is in use, a gap can be provided between the annular platform and the top of the side wall of the first cavity 121 to facilitate the connection between the first cavity 121 and the bottle body 110, improving the connection stability between the bottle body 110 and the cap 120. Therefore, the safety of the milk bottle is effectively improved, allowing it to maintain its original storage state even when subjected to shaking or impact during transportation.

[0034] According to the fresh milk bottle provided in this embodiment, by providing a second annular groove 114 at a second position at the bottom of the bottle body 110, and making the groove engage with the first annular protrusion 1211 and the second annular protrusion 1212 on the bottle cap 120, the connection stability between the bottle body 110 and the bottle cap 120 can be significantly improved when the fresh milk bottle is in use. Specifically, in use, the top surface of the first annular protrusion 1211 abuts against the top wall of the second annular groove 114, and the bottom surface of the second annular protrusion 1212 abuts against the bottom wall of the second annular groove 114, thereby forming a stable limit in three dimensions and preventing the bottle body 110 from loosening or shifting at the connection point. The annular platform formed on the lower part of the outer wall of the bottle body 110 abuts or gap-fits with the top of the side wall of the first cavity 121 when the fresh milk bottle is in use. This further enhances the limiting stability in the use state and also optimizes the transition structure between the bottle body 110 and the cap 120, making the installation process smoother and avoiding structural deformation or sealing failure caused by excessive tightness or instability. The fresh milk bottle provided in this embodiment achieves stable switching and sealing protection of the fresh milk bottle in different working states, improving the overall user experience while effectively enhancing the structural safety and freshness preservation reliability of the product during storage and transportation.

[0035] In some embodiments, such as Figure 2 , Figure 3 As shown, the outer wall of the dispensing part 111 extends outward to form a third annular protrusion 1111, and the inner wall of the mounting groove 123 is recessed outward to form a third annular groove 1231. When the fresh milk bottle is in use, the third annular protrusion 1111 is installed in the third annular groove 1231. The middle of the outer wall of the dispensing part 111 can extend outward to form a third annular protrusion 1111, and the inner wall of the mounting groove 123 can be recessed outward to form a third annular groove 1231 that mates with the third annular protrusion 1111. When the dispensing part 111 is installed in the mounting groove 123, the third annular protrusion 1111 can be installed in the third annular groove 1231, so that the dispensing part 111 and the mounting groove 123 of the bottle cap 120 are firmly connected. In use, shaking in the vertical or horizontal direction will not affect the fit between the dispensing part 111 and the mounting groove 123. By installing the third annular protrusion 1111 into the third annular groove 1231, the dispensing part 111 is tightly connected to the mounting groove 123 when the fresh milk bottle is in use. This ensures that there is no gap between the bottom surface of the dispensing part 111 and the top surface of the mounting groove 123, and that the connection between the outer periphery of the dispensing part 111 and the inner wall of the mounting groove 123 is stable. This effectively prevents air or external impurities from entering between the dispensing part 111 and the mounting groove 123, resulting in better sealing. This further improves the sealing performance between the bottle body 110 and the bottle cap 120, giving the bottle body 110 better freshness preservation performance.

[0036] According to the fresh milk bottle provided in this embodiment, a third annular protrusion 1111 is formed on the outer wall of the liquid outlet 111, and a third annular groove 1231 is formed on the inner wall of the mounting groove 123 to cooperate with it. When the fresh milk bottle is in use, the third annular protrusion 1111 is installed in the third annular groove 1231, which can further improve the connection stability and sealing between the liquid outlet 111 and the mounting groove 123. It can prevent the liquid outlet 111 from sliding due to gravity or reverse thrust in the vertical direction, and at the same time limit its shaking or rotation in the horizontal direction, effectively enhancing the structure's anti-disturbance capability. Through the connection between the third annular protrusion 1111 and the third annular groove 1231, the bottom surface of the liquid outlet 111 and the top surface of the mounting groove 123 can be fitted together without gap, and the outer peripheral sidewall of the liquid outlet 111 can be in close contact with the inner sidewall of the mounting groove 123, thereby preventing external impurities such as air, moisture or dust from entering the installation area and significantly improving the overall sealing performance. During the dispensing process, the emulsion flows out only through a sealed path, making it difficult for the external environment to interfere with the internal medium, thus maintaining the purity and stability of the emulsion. This not only enhances the secure fit between the dispensing section 111 and the cap 120, but also improves the preservation effect, preventing leakage, contamination, or emulsion oxidation caused by structural loosening, and further extending the shelf life of the emulsion.

[0037] In some embodiments, such as Figure 3 As shown, when the milk bottle is in use, the stepped surface 112 abuts against the bottom surface of the first cavity 121. When the milk bottle is in use, the annular stepped surface 112 formed on the upper part of the dispensing section 111 can abut against the bottom surface of the first cavity 121, i.e., the annular plane formed on the upper outer periphery of the mounting groove 123. When the milk bottle is in use, the dispensing section 111 is installed in the mounting groove 123, allowing the needle 130 to pierce the sealing film 115. To prevent external air and impurities from entering between the cap 120 and the bottle body 110 and affecting the milk stored in the bottle body 110, the stepped surface 112 abuts against the bottom surface of the first cavity 121, and the bottom surface of the dispensing section 111 abuts against the bottom surface of the mounting groove 123, ensuring a seamless connection between the cap 120 and the bottle body 110, effectively preventing gas and impurities from entering the bottle body 110 and affecting the preservation of the milk. This ensures a stable and seamless connection between the bottle body 110 and the cap 120, effectively improving the connection stability between the bottle body 110 and the cap 120, as well as the overall preservation performance of the freshness-preserving emulsion bottle.

[0038] According to the fresh-keeping emulsion bottle provided in this embodiment, the stepped surface 112 abuts against the bottom surface of the first cavity 121, ensuring that after the liquid outlet 111 is installed, there are no gaps in the contact areas between the bottle body 110 and the bottle cap 120. This effectively blocks the possibility of air, moisture, or small particulate impurities entering the interior of the bottle body 110 from the gaps in the side wall of the bottle cap 120, improving the connection stability and sealing performance between the bottle cap 120 and the bottle body 110. The tight fit between the stepped surface 112 and the bottom surface of the first cavity 121 not only enhances the axial positioning stability of the bottle body 110, preventing shaking or dislocation caused by compression or rebound during use, but also significantly improves the overall vibration resistance and sealing integrity of the structure. This seamless structural fit allows the fresh-keeping emulsion bottle to maintain a highly efficient sealed state during storage, transportation, and use, further improving the overall sealing effect and preservation ability of the bottle, making the emulsion quality more stable and safer during use.

[0039] In some embodiments, the tip extension length of the needle 130 is less than or equal to the height of the dispensing portion 111. Since the tip of the needle 130 needs to pierce the film covering the bottom of the dispensing portion 111 during use, the emulsion in the bottle 110 can flow out along the needle 130, enter the dispensing assembly, and finally flow out to the outside. When the remaining amount of emulsion in the bottle 110 is low, and the emulsion level is lower than the height of the needle tip 130, the emulsion will accumulate in the bottle 110 and cannot be supplied to the user, resulting in waste. Therefore, the length of the needle tip extending into the bottle 110 can be less than or equal to the height of the dispensing portion 111, allowing more emulsion to pass through the needle 130 into the dispensing portion 111, reducing emulsion waste. Since the cross-sectional area of ​​the dispensing portion 111 is smaller than the cross-sectional area of ​​the upper part of the bottle 110, there is less emulsion at the dispensing portion 111, and making the tip extension length of the needle 130 less than or equal to the height of the dispensing portion 111 further reduces emulsion waste. In addition, in some embodiments, an inwardly inclined slope can be formed from the top of the liquid outlet 111, so that the emulsion can flow back into the needle 130 along the slope, making the liquid outlet smoother and avoiding waste caused by the accumulation of emulsion on the plane above the liquid outlet 111.

[0040] According to the emulsion bottle provided in this embodiment, by setting the length of the tip of the needle 130 extending towards the bottle body 110 to be less than or equal to the height of the dispensing section 111, the emulsion in the bottle body 110 can be utilized to the maximum extent, reducing emulsion residue and waste. When the emulsion gradually decreases and approaches the bottom of the bottle body 110, if the tip of the needle 130 is located at or near the bottom of the dispensing section 111, even if the emulsion level is lower than other parts of the bottle body 110, the remaining emulsion can still be smoothly discharged through the needle 130, ensuring more efficient use of the emulsion, extending the usage cycle, and reducing waste. The top of the dispensing section 111 can also be provided with an inwardly inclined slope structure. This structure can effectively guide the emulsion to naturally converge along the slope to the needle 130 inlet. Even if the emulsion adheres to the inner wall or periphery of the dispensing section 111, it can be guided back by the slope, thereby avoiding residue and waste caused by the accumulation of emulsion on a local plane.

[0041] In some embodiments, such as Figure 2 , Figure 3 As shown, the liquid dispensing assembly may include: a conduit 140 and a liquid dispensing pipe 150. The fresh milk bottle may also include: a pump body 160 and multiple movable rotors 170.

[0042] A conduit 140 is disposed within the second cavity 122 and communicates with the needle 130. The conduit 140 can be a flexible tube, disposed within the second cavity 122 such that one end of the conduit 140 communicates with the needle 130 and the other end communicates with the dispensing tube 150. When the milk bottle is in storage, the needle 130 is separated from the plastic film, and there is no milk in either the needle 130 or the conduit 140. When the milk bottle is in use, the needle 130 punctures the plastic film, allowing the milk to flow out from the needle 130. The milk flows into the conduit 140 connected to the needle 130 and then along the conduit 140 to the dispensing tube 150, thus dispensing the milk.

[0043] A discharge pipe 150 is installed on the side wall of the second cavity 122 and communicates with the conduit 140. The discharge pipe 150 can be a conduit 140 fixedly installed on the side wall of the second cavity 122. The discharge pipe 150 can be L-shaped, with one end of its outer wall fixedly installed on the side wall of the second cavity 122, thus communicating with the interior of the second cavity 122. The discharge pipe 150 communicates with the conduit 140 inside the second cavity 122, allowing the emulsion within the conduit 140 to flow to the discharge pipe 150 and be discharged outwards. The other end of the discharge pipe 150 extends vertically downwards, forming an outlet at its lower end for the emulsion to flow out. The emulsion can flow along the extension direction of the discharge pipe 150 and ultimately flow out through the outlet to the outside of the preservation emulsion bottle, supplying it to the user. The tight connection between the outlet pipe 150 and the conduit 140 ensures good sealing of the emulsion as it flows from the conduit 140 to the outlet pipe 150, preventing it from coming into contact with the outside environment.

[0044] A pump body 160 is disposed within a second cavity 122. The pump body 160 may be disposed within the second cavity 122, and an annular track for mounting a movable rotor 170 may be provided within the pump body 160. This allows the rotor shaft of the movable rotor 170 to be mounted on the track within the pump body 160 and to slide along the track. The pump body 160 may be a peristaltic pump, allowing the movable rotor 170 to rotate under the drive of a motor 190 and slide along the track within the pump body 160.

[0045] Multiple movable rotors 170 are installed inside the pump body 160, and a conduit 140 surrounds the outside of the movable rotors 170. The movable rotors 170 are used to rotate and compress the conduit 140 under the drive of the motor 190. The movable rotors 170 can be installed inside the pump body 160, so that the movable rotors 170 can rotate inside the pump body 160 under the drive of the motor 190. The distance between two adjacent movable rotors 170 is fixed. The rotors can compress the conduit 140, and the movable rotors 170 can gradually push the air or emulsion in the conduit 140 outward as the motor shaft rotates. Because the movable rotors 170 compress the conduit 140, the conduit 140 forms an independent sealed space between two adjacent movable rotors 170, and the distance between two adjacent movable rotors 170 is fixed, so that the amount of air or emulsion squeezed outward with each rotation is limited and the same. This allows for precise control of the liquid output each time while achieving good airtight preservation performance.

[0046] According to the fresh-keeping emulsion bottle provided in this embodiment, a closed, controllable, and stable emulsion delivery system is constructed by setting up a conduit 140, an outlet pipe 150, a pump body 160, and multiple movable rotors 170. This system achieves efficient emulsion export while effectively preventing the emulsion from contacting outside air during the delivery path, significantly improving the product's freshness preservation performance and dispensing accuracy. The conduit 140 is located within the second cavity 122, communicating with the needle 130, and employs a flexible hose structure, which can adapt to the complex spatial layout within the bottle body 110 and cap 120, improving internal arrangement flexibility. After the fresh-keeping emulsion bottle switches from storage to use, the needle 130 punctures the sealing film 115, allowing the emulsion to flow into the conduit 140 through the needle 130 and then be discharged through the outlet pipe 150, forming a stable and closed delivery path. The conduit 140 and the outlet pipe 150 are tightly connected, forming a continuous sealed path to prevent emulsion leakage or air contamination, thereby improving the safety and cleanliness of the emulsion. The pump body 160 contains multiple movable rotors 170 that can be driven to rotate by a motor 190. The movable rotors 170 contact and press against the conduit 140, and as driven by the motor 190, sequentially push the liquid within the conduit 140 to flow in the discharge direction. The distance between the multiple movable rotors 170 is fixed and they can move synchronously. The conduit 140 rotates with the movable rotors 170, ensuring a constant and controllable dosage of emulsion discharged with each rotation.

[0047] In some embodiments, such as Figure 2 , Figure 3 As shown, the fresh-keeping emulsion bottle may further include a sealing cover 180, which covers the bottom of the second cavity 122. The sealing cover 180 covers the bottom of the second cavity 122, allowing the pump body 160 to be securely installed within the second cavity 122. Simultaneously, the sealing cover 180 seals the second cavity 122, preventing the emulsion in the conduit 140 and the outlet pipe 150 within the second cavity 122 from contacting the outside environment, further enhancing the sealing effect of the fresh-keeping emulsion bottle. According to the fresh-keeping emulsion bottle provided in this embodiment, by setting the sealing cover 180, the entire second cavity 122 can form a closed space when the bottle body 110 is in use, effectively isolating the conduit 140, the outlet pipe 150, and the pump body 160 from air exchange with the external environment, thereby preventing the evaporation of moisture or oxidation of active ingredients in the emulsion, and achieving the preservation of the emulsion. The sealing cover 180 can also ensure the stable installation of the pump body 160 inside the bottle cap 120, preventing it from shifting due to shaking or sliding down due to gravity, thus improving the stability of the fresh milk bottle.
