Description

Technical Field

[0001] This technical solution relates to the field of cosmetic tools technology, specifically to an isolated cosmetic bottle. Background Technology

[0002] A cosmetic bottle is a tool specifically designed for use with applicators to apply cosmetics (such as foundation, lipstick, eyeshadow, concealer, etc.) evenly and precisely to specific areas of the skin or face.

[0003] For example, Chinese patent CN220001091U discloses a replaceable cosmetic container and a replaceable inner screen, including a top cover and a bottle body. The top cover and the bottle body are detachably connected. The bottle body includes an inner liner and an outer bottle. The mouth and inner wall of the outer bottle are provided with several spiral guide grooves. The outer wall of the inner liner is provided with several guide ribs that match the spiral guide grooves. The guide ribs can be screwed in or out along the spiral guide grooves.

[0004] In the aforementioned replaceable cosmetic containers, the top cover is usually equipped with a brush handle. When the top cover is connected to the bottle, the brush head at the end of the brush handle will be immersed in the makeup inside the bottle for a long time. During use, the top cover needs to be opened and closed repeatedly to apply the cream. The brush head comes into contact with the skin and may carry microorganisms (such as bacteria and mold). The brush head is in contact with the makeup for a long time, which makes it easy for it to become a breeding ground for microorganisms. Moreover, users do not have the habit of regularly deep cleaning the brush head. Wiping the surface with a tissue is not enough to completely remove the residue. The pollution continues to accumulate, causing the product to deteriorate, shorten its shelf life, and result in poor hygiene. Summary of the Invention

[0005] This technical solution aims to improve the poor hygiene caused by the brush head carrying bacteria being immersed in makeup for a long time, by providing an isolated cosmetic bottle.

[0006] The purpose of this technical solution is achieved as follows: An isolating cosmetic bottle includes a bottle body and a bottle cap. The bottle body is provided with a partition portion, which divides the bottle body into a first chamber and a second chamber. The first chamber is used to contain makeup. The bottle cap is eccentrically provided with a brush rod. The bottle cap and the bottle body are provided with a quick-release structure. When the bottle cap is detachably connected to the bottle body through the quick-release structure, the brush rod is placed in the second chamber.

[0007] Through the above technical solution, when a type of isolated cosmetic bottle is in normal use, the brush handle is eccentrically positioned so that it can be inserted into a second chamber that is also eccentrically positioned. The bottle cap can then be detachably connected to the bottle body via a quick-release structure, making assembly efficient and convenient. The makeup is completely contained in a first chamber that is independently separated by a partition. Moreover, the brush handle can avoid the position of the first chamber when inserted into the chamber. This physical isolation design effectively prevents the brush head from continuing to be immersed in the makeup after use, thereby achieving separate storage of the makeup and the brush handle after use, and improving the long-term hygiene of the product.

[0008] Preferably, the bottle cap is rotatably disposed relative to the inner core, the inner core has a mounting portion that protrudes relative to the outer bottle, and the quick-release structure includes: A snap-fit ​​portion 1 is disposed on the outer wall of the mounting portion, and the snap-fit ​​portion 1 has a guide slope 1 and an abutment surface 1; A limiting part is provided on the outer wall of the mounting part. The limiting part is located axially opposite to the outer side of the first snap-fit ​​part. A limiting channel is formed between the limiting part and the first snap-fit ​​part, and the limiting channel is used for the third snap-fit ​​part to pass through. A second snap-fit ​​part is correspondingly disposed on the inner wall of the bottle cap, and the second snap-fit ​​part has a second abutment surface; The third snap-fit ​​part is correspondingly disposed on the inner wall of the bottle cap. The third snap-fit ​​part and the second snap-fit ​​part are aligned along the rotation direction of the bottle cap and are spaced apart by a clearance groove. The third snap-fit ​​part has a guide arc surface at one end near the second snap-fit ​​part, and the third snap-fit ​​part has a guide slope two. The bottle cap moves between a first position and a second position. When the bottle cap is in the first position, the first abutting surface and the second abutting surface abut against each other, the second locking part and the limiting part abut against each other along the axial direction, the upper part of the first locking part is engaged in the relief groove, and the quick-release structure is in a locked state. After the bottle cap is guided to the second position by the cooperation of the guide arc surface and the guide slope, the quick-release structure is in an unlocked state.

[0009] With the above technical solution, when the bottle cap is placed on the mounting part, it is initially in the second position (unlocked state). During the process of switching the bottle cap from the second position to the first position by rotating the bottle cap, the third locking part slides into the limited channel through the second guide slope. The third locking part advances radially along the limited channel until the second abutting surface abuts against the first abutting surface, restricting further rotation. The upper end of the first locking part is correspondingly limited in the relief groove, the arc surface is opposite to the first guide slope, and the second locking part abuts against the first limiting part axially, restricting the bottle cap from being pulled out axially from the mounting part. At this time, the bottle cap is in the first position, and the quick-release structure is in the locked state. When unlocking is required, the bottle cap is rotated in the opposite direction, the arc surface slides along the first guide slope, the third locking part slides into the limited channel and continues to retract until it returns to the second position. The quick-release structure is in the locked state, and the bottle cap and bottle body can be separated. The bottle cap can be quickly disassembled by rotating it at a small angle, which is convenient to operate and use.

[0010] Preferably, the size of the second snap-fit ​​portion is larger than the size of the defined channel, and the size of the third snap-fit ​​portion is smaller than that of the second snap-fit ​​portion.

[0011] Through the above technical solution, the size of the locking part three is small, ensuring that it can be squeezed through the limited channel, while the size of the locking part two is large, which restricts its passage through the limited channel, preventing the quick-release structure from being unable to lock and the bottle cap from continuously rotating, thereby improving structural stability.

[0012] Preferably, at least two quick-release structures are provided, and the two quick-release structures can switch between locked and unlocked states simultaneously.

[0013] With the above technical solution, two quick-release structures are set along the circumference of the bottle cap, and the multi-point fixing structure further improves the stability of the disassembly and assembly between the bottle cap and the bottle body.

[0014] Preferably, the mounting part has an annular groove along its outer peripheral wall, and a sealing ring is embedded in the annular groove.

[0015] With the above technical solution, after the bottle cap is installed, the inner wall of the bottle cap and the sealing ring are tightly abutted, reducing the connection between the bottle cap and the mounting part, thereby improving the internal sealing performance.

[0016] Preferably, the depth of the first chamber is less than that of the second chamber; The span from the end of the brush rod furthest from the bottle cap to the lower edge of the bottle cap is adapted to the cavity depth of the first chamber.

[0017] Through the above technical solution, the second chamber with a larger cavity depth is adapted to the length of the brush handle so as to fully accommodate it; when the brush handle dips in makeup, the lower edge of the bottle cap will inevitably touch the upper edge of the mounting part. By using the first chamber with a smaller cavity depth, combined with the usable length of the brush handle extending relative to the bottle cap, it is ensured that the brush head can smoothly contact and dip in the makeup at the bottom, thereby reducing the difficulty of dipping in dead corners and improving the utilization efficiency of makeup.

[0018] Preferably, the inner core is provided with a compartment cover, which engages with the opening end of the first chamber, and the compartment cover has an edge-blocking portion along its edge.

[0019] The above technical solution achieves a sealing effect on the first chamber by fitting the opening end of the first chamber with the appropriate opening latch, which helps to keep the inside of the chamber clean and reduce the risk of cosmetic contamination. The edge part abuts against the edge of the opening of the first chamber to ensure that the lid is securely closed, and by prying open the edge part, it is easy to remove the lid from the opening.

[0020] Preferably, the inner core has a limiting portion protruding along the outer wall, and the inner wall of the outer bottle has a corresponding limiting groove for fitting the limiting portion.

[0021] The above technical solution, through the fitting structure of the limiting part and the limiting groove, restricts the relative rotation of the inner core after it is installed on the outer bottle, thereby improving assembly stability.

[0022] Preferably, the partition portion is arc-shaped.

[0023] With the above technical solutions, most cosmetic bottles are cylindrical or curved. The curved partition can make full use of the internal space of the bottle, ensuring that the brush handle can rotate back and forth in the second chamber, while reducing the space ratio of the second chamber to the first chamber, thus accommodating more makeup.

[0024] The key and beneficial technical effects of this technical solution compared to existing technologies are: 1. This technical solution physically separates the first chamber and the second chamber through a partition. The first chamber contains the makeup and the second chamber contains the brush handle. This allows for the separate storage of the brush head and makeup after use, effectively preventing the brush head from contaminating the makeup and improving the hygiene of the product for long-term use. 2. This technical solution uses an eccentric setting for the brush rod and a second chamber corresponding to the brush rod position, so that when the brush rod needs to be inserted into the second chamber, it does not need to pass through the position of the first chamber, thus reducing the occurrence of impurities falling out. 3. This technical solution makes the depth of the first chamber smaller than that of the second chamber. When the brush handle picks up makeup, the lower edge of the cap will abut against the upper edge of the mounting part, ensuring that the brush head can smoothly contact and pick up the makeup at the bottom, thereby reducing the difficulty of picking up makeup in dead corners and improving the utilization efficiency of makeup.

Sealing ring. Detailed Implementation

[0027] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0028] Example: See Figure 1 , Figure 3 and Figure 4 An isolated cosmetic bottle has a cylindrical shape and includes a bottle body 1 and a bottle cap 4. The bottle body 1 includes an outer bottle 11 and an inner core 12. The outer bottle 11 has a cavity inside. The lower part of the inner core 12 is embedded in the cavity of the outer bottle 11. The upper part of the inner core 12 protrudes from the outer bottle 11 and has a mounting part 7.

[0029] The inner core 12 can be made by one-time injection molding. Its outer wall has two symmetrically arranged limiting parts 161 protruding. The outer bottle 11 has two limiting grooves 162 corresponding to the positions of the two limiting parts 161 along its inner peripheral wall. Each limiting groove 162 has an opening that extends upward and outward, so that the two limiting parts 161 can be fitted into each other through the through ends of the two limiting grooves 162, initially limiting the relative rotation between the inner core 12 and the outer bottle 11. Subsequently, it can be further reinforced by bonding, hot melting, or snap-fitting to fix the inner core 12 and the outer bottle 11.

[0030] The inner core 12 has an integrally formed partition 2, which is arc-shaped. The partition 2 divides the inner core 12 into two independent first chambers 31 and second chambers 32. The arc surface of the partition 2 protrudes towards the first chamber 31. The first chamber 31 is C-shaped (or approximately semi-circular crescent-shaped) and is used to hold makeup. Its opening size is larger than that of the second chamber 32, and its depth is less than that of the second chamber 32. The design of a large opening combined with a shallow depth makes it easy for the brush to pick up makeup. The inner core 12 is provided with a cover 14, which is shaped to match the first chamber 31. The cover 14 has a ring of abutment 15 along its edge. When the cover 14 is snapped into the first chamber 31, the abutment 15 abuts against the edge of the inner core 12 corresponding to the opening of the first chamber 31, thereby achieving a sealing effect on the first chamber 31.

[0031] The mounting part 7 has an annular groove 18 along its outer peripheral wall. A suitable sealing ring 19 is embedded in the annular groove 18. When the bottle cap 4 is installed, the sealing ring 19 abuts against the bottom of the annular groove 18 and the corresponding inner side wall of the bottle cap 4, reducing the gap between the mounting part 7 and the bottle cap 4, improving the sealing performance of the internal space of the bottle body 1 and the bottle cap 4, and reducing leakage.

[0032] See Figure 4 , Figure 5 and Figure 6 The bottle cap 4 is rotatably mounted relative to the bottle body 1. A quick-release structure 6 is provided between the bottle cap 4 and the bottle body 1. The bottle cap 4 is detachably connected to the bottle body 1 through the quick-release structure 6. Specifically, there are at least two quick-release structures 6 that can be detachably connected. Each quick-release structure 6 includes a first snap-fit ​​part 61, a limiting part 62, a second snap-fit ​​part 63, and a third snap-fit ​​part 64. The first snap-fit ​​part 61 and the limiting part 62 both protrude from the outer wall of the mounting part 7. The limiting part 62 is located axially opposite to the outside of the first snap-fit ​​part 61. A limiting channel 10 is formed between the limiting part 62 and the first snap-fit ​​part 61. The width of the channel is limited to the span distance between the opposite side walls of the limiting part 62 and the first snap-fit ​​part 61. The first snap-fit ​​part 61 has a guide slope 81, which is inclined downward toward the outer bottle 11. The other end of the first snap-fit ​​part 61 away from the guide slope 81 has an abutment surface 91.

[0033] Both the second snap-fit ​​part 63 and the third snap-fit ​​part 64 protrude from the inner wall of the bottle cap 4, and are arranged at intervals along the rotation direction of the bottle cap 4, so that a clearance groove 13 is left between the second snap-fit ​​part 63 and the third snap-fit ​​part 64. The thickness of the third snap-fit ​​part 64 is less than the thickness of the second snap-fit ​​part 63. The end face of the second snap-fit ​​part 63 near the third snap-fit ​​part 64 has a second abutment surface 92. The end of the third snap-fit ​​part 64 opposite to the second abutment surface 92 has a guide arc surface 17, and the other end opposite to the guide arc surface 17 also has a guide slope 82. The second guide slope 82 is arranged in the opposite direction to the first guide slope 81.

[0034] See Figure 7 The bottle cap 4 is fitted on the outside of the mounting part 7 and can rotate between the first position and the second position. The inner side of the bottle cap 4 is eccentrically connected to the brush rod 5, the end of which is usually equipped with a brush head (such as bristles). When the brush rod 5 is inserted into the second chamber 32, the rotation of the bottle cap 4 will drive the brush rod 5 to move synchronously due to the eccentric setting of the brush rod 5, so that it can move within the length of the opening of the second chamber 32. Both quick-release structures 6 are arranged within the movable range of the brush rod 5 and can be triggered simultaneously within this range. This ensures that even if the brush rod 5 comes into contact with the inner wall of the second chamber 32 during the movement, the quick-release structure 6 can still be triggered normally, avoiding the failure of the quick-release function due to the position restriction of the brush rod 5.

[0035] When the bottle cap 4 is in the first position, the quick-release structure 6 is in the unlocked state. At this time, the locking part 3 64 is aligned with the limiting channel 10. During the process of rotating the bottle cap 4 from the first position to the second position, the guide slope 2 82 of the locking part 3 64 contacts the locking part 1 61. The slope guides the locking part 3 64 into the limiting channel 10. As the bottle cap 4 continues to rotate, the locking part 3 64 advances along the limiting channel 10 until the abutting surface 2 92 of the locking part 2 63 abuts against the abutting surface 1 91, preventing the bottle cap 4 from rotating further. At this time, the bottle cap 4 reaches the second position. The guide surface 17 is opposite to the guide slope 1 81, and the upper end of the locking part 1 61 is correspondingly limited in the relief groove 13. When the bottle cap 4 is pulled out axially upward from the mounting part 7, the locking part 2 63 abuts axially against the limiting part 62, restricting the bottle cap 4 from being pulled out. Both quick-release structures 6 can switch between the locked and unlocked states at the same time. At this time, both quick-release structures 6 are in the locked state.

[0036] When the bottle cap 4 needs to be removed, rotate the bottle cap 4 from the second position back to the first position. The guide surface 17 of the locking part 3 64 slides along the guide slope 81 of the locking part 1 61, guiding the locking part 3 64 to slide back into the limiting channel 10 and continue to retract along the channel until the bottle cap 4 returns to the first position. Then, the quick-release structure 6 is unlocked, the bottle cap 4 is separated from the bottle body 1, the bottle cap 4 can be pulled out, and the brush rod 5 can be used to pick up makeup. The bottle cap 4 can be quickly disassembled by rotating it at a small angle, making it convenient to operate and use. The distance from the end of the brush rod 5 away from the bottle cap 4 to the lower edge of the bottle cap 4 is adapted to the cavity depth of the first chamber 31. When picking up makeup, the lower edge of the bottle cap 4 abuts against the upper edge of the mounting part 7. At this time, the length of the brush rod 5 that can be inserted into the first chamber 31 is adapted to the cavity depth of the first chamber 31, ensuring smooth and sufficient picking up of makeup. This reduces the difficulty of picking up makeup in hard-to-reach areas and improves the efficiency of makeup utilization.

[0037] The specific work process of this plan is as follows: This technical solution features a quick-release structure 6 between the bottle cap 4 and the bottle body 1. The bottle cap 4 is detachably connected to the bottle body 1 via the quick-release structure 6. At this time, the brush handle 5 on the bottle cap 4 is placed in the second chamber 32 separated by the partition 2, while the makeup is completely contained in the independent first chamber 31. This physical isolation design effectively prevents the brush head of the brush handle 5 from continuing to be soaked in the makeup after use. In the second chamber 32, the makeup and the brush handle 5 are stored separately after use, improving the long-term hygiene of the product.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this technical solution. Those skilled in the art should understand that this technical solution is not limited to the above embodiments.
