Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging technology, and in particular to a self-sealing essence bottle. Background Technology

[0002] As a highly concentrated and active skincare product, serums are extremely sensitive to environmental factors, especially light, temperature, and oxygen, in terms of their core active ingredients. Therefore, the core function of serum packaging is not only storage and retrieval, but also maximizing the protection of the contents, maintaining their stability and freshness, and ensuring efficacy from the first use to the last.

[0003] Currently, most mainstream serum packaging bottles on the market adopt a traditional wide-mouth bottle structure, mainly consisting of a bottle body, a cap, and possibly an inner stopper or dropper. The top of the bottle has an open opening, which is connected to the cap via a threaded or snap-fit ​​mechanism to achieve a seal. To use, the user unscrews or pulls off the cap, pours out the serum, or uses the included dropper to draw it from the bottle. After use, the cap is closed again.

[0004] However, the sealing of this traditional open-top bottle relies on user habits and is unreliable. This sealing method depends entirely on the user tightening the cap promptly and accurately after each use. In real-world scenarios, users may fail to seal properly due to haste, negligence, or loss of the cap, leaving the bottle open for extended periods. This greatly accelerates the oxidation, deterioration, and contamination of the serum, and may even cause the contents to spoil prematurely before their expiration date. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a self-sealing essence bottle. This self-sealing essence bottle allows for convenient pouring of the essence when needed, and automatically seals the bottle after use, preventing users from failing to properly seal the bottle due to haste, negligence, or loss of the cap.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a self-sealing essence bottle, comprising a bottle body, a bottle mouth on the bottle body, a self-sealing assembly inside the bottle mouth, the self-sealing assembly including a fitting part having a liquid outlet channel that seals with the bottle mouth, a sealing member movably disposed within the liquid outlet channel, the sealing member including a plug and an elastic part connected to the bottom of the plug, a limiting part abutting against the elastic part within the liquid outlet channel, and the sealing member further including a pressing part connected to the top of the plug and extending out of the liquid outlet channel, pressing the pressing part to create a liquid outlet gap between the sealing member and the side wall of the liquid outlet channel. When using this self-sealing serum bottle, the bottle is inverted and the pressing part is pressed to create a gap between the plug and the side wall of the dispensing channel. The serum flows out along the gap. After use, the plug automatically resets due to the elasticity of the elastic part, automatically sealing the outlet of the dispensing channel. This prevents the bottle from failing to seal properly due to the user's haste, negligence, or loss of the cap.

[0007] In the above technical solution, preferably, the pressing part is a guide rod with an outer diameter matching the inner diameter of the outlet side of the liquid outlet channel. The guide rod has a flow groove on its side wall, and the flow groove communicates with the liquid outlet gap. This structure guides the movement trajectory of the plug, preventing the plug from deflecting and causing the outlet of the liquid outlet channel to fail to seal effectively after resetting.

[0008] In the above technical solution, preferably, the flow groove is arranged along the axial direction of the guide rod.

[0009] In the above technical solution, preferably, the elastic part includes a plurality of spiral ribs evenly distributed around the outer edge of the bottom of the plug, the plurality of spiral ribs being integrally injection molded with the plug, and the bottom of the spiral ribs abutting against the limiting part. This structure facilitates the processing of the sealing component; during processing, the spiral ribs and the plug can be integrally injection molded, eliminating the need for a spring and preventing the metal elements in the spring from reacting with the essence.

[0010] In the above technical solution, preferably, the bottom of the spiral rib is integrally injection molded with a flexible positioning ring, and the inner end of the liquid outlet channel is provided with the limiting part, which is a first limiting ring. The bottom of the flexible positioning ring abuts against the first limiting ring. This structure integrates the plug, spiral rib, and flexible positioning ring into a single injection mold, facilitating the processing of the sealing component and making installation convenient. The plug is inserted upwards into the liquid outlet channel, and then the flexible positioning ring is deformed by extrusion pressure, passing through the first limiting ring, with its bottom abutting against the first limiting ring to complete assembly.

[0011] In the above technical solution, preferably, the bottom of the first limiting ring is provided with a flared portion to guide the flexible positioning ring. By providing the flared portion, the flexible positioning ring can be deformed and guided when squeezed, further facilitating assembly.

[0012] In the above technical solution, preferably, the liquid outlet channel has a narrowing section with a gradually decreasing diameter near the outlet side. This structure allows the gap between the plug and the inner wall of the liquid outlet channel to gradually widen as the plug is pushed into the outlet channel when the pressing part is pressed, enabling adjustment of the pressing pressure to control the dispensing speed of the essence.

[0013] In the above technical solution, preferably, the outer wall of the mating component is provided with a second limiting ring, and the outer wall of the mating component below the second limiting ring is press-fitted with the inner wall of the bottle mouth. This structure facilitates the sealing assembly of the mating component onto the bottle mouth and ensures consistent positioning.

[0014] In the above technical solution, preferably, the outer wall of the bottle mouth is threadedly fitted with the bottle cap.

[0015] In the above technical solution, preferably, the inner wall of the top of the bottle cap is provided with an annular protrusion. When the bottle cap is closed, the annular protrusion abuts against the mating part to seal the liquid outlet channel, and the pressing part is located inside the annular protrusion. This structure can further increase the sealing of the liquid outlet channel when the bottle cap is screwed onto the bottle neck, avoiding accidental leakage of the essence due to factors such as violent shaking.

[0016] Compared with the prior art, this utility model has the following beneficial effects: When the essence in this self-sealing essence bottle is taken out, the bottle is inverted and the pressing part is pressed to create a liquid outlet gap between the plug and the side wall of the liquid outlet channel. The essence flows out along the liquid outlet gap. After the essence is taken out, the plug is automatically reset by the elastic force of the elastic part, and the plug automatically seals the outlet of the liquid outlet channel, thereby avoiding the bottle from failing to be properly sealed due to the user's haste, negligence or loss of the bottle cap.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1 to 4 A self-sealing essence bottle includes a bottle body 1 with a bottle mouth 2. A self-sealing assembly 3 is provided inside the bottle mouth 2. The self-sealing assembly 3 includes a fitting part 5 that seals with the bottle mouth 2 and has an internal liquid outlet channel 4. A sealing part 6 is movably disposed inside the liquid outlet channel 4. The sealing part 6 includes a plug 7 and an elastic part 8 connected to the bottom of the plug 7. A limiting part 9 that abuts against the elastic part 8 is provided inside the liquid outlet channel 4. The sealing part 6 also includes a pressing part 10 that is connected to the top of the plug 7 and extends out of the liquid outlet channel 4. Pressing the pressing part 10 causes the sealing part 6 to create a liquid outlet gap with the side wall of the liquid outlet channel 4. When using this self-sealing essence bottle, the bottle body 1 is inverted and the pressing part 10 is pressed to create a liquid outlet gap between the plug 7 and the side wall of the liquid outlet channel 4. The essence flows out along the liquid outlet gap. After use, the plug 7 is automatically reset by the elastic force of the elastic part 8, and the plug 7 automatically seals the outlet of the liquid outlet channel 4, thus avoiding the bottle body 1 from failing to be properly sealed due to the user's haste, negligence, or loss of the bottle cap 15.

[0022] In this embodiment, the pressing part 10 is a guide rod 101 with an outer diameter matching the inner diameter of the outlet side of the liquid outlet channel 4. The guide rod 101 has a flow groove 11 on its side wall, which communicates with the liquid outlet gap. This structure can guide the movement trajectory of the plug 7, avoiding the inability to effectively seal the outlet of the liquid outlet channel 4 after the plug 7 is reset due to reasons such as deflection of the plug 7.

[0023] In this embodiment, the flow groove 11 is arranged along the axial direction of the guide rod 101.

[0024] In this embodiment, the elastic part 8 includes three spiral ribs 81 evenly distributed around the outer edge of the bottom of the plug 7. The three spiral ribs 81 are integrally injection molded with the plug 7, and the bottom of the spiral ribs 81 abuts against the limiting part 9. This structure facilitates the processing of the sealing part 6. During processing, the spiral ribs 81 and the plug 7 can be integrally injection molded, eliminating the need for springs and avoiding the reaction between the metal elements in the spring and the essence.

[0025] In this embodiment, a flexible positioning ring 82 is integrally injection molded at the bottom of the spiral rib 81. A limiting part 9 is provided at the inner end of the liquid outlet channel 4, and the limiting part 9 is a first limiting ring. The bottom of the flexible positioning ring 82 abuts against the first limiting ring. This structure integrates the plug 7, spiral rib 81, and flexible positioning ring 82 into a single injection mold, which facilitates the processing of the sealing component 6 and makes installation convenient. The plug 7 is inserted into the liquid outlet channel 4 with its face upward, and then the flexible positioning ring 82 is deformed by extrusion pressure, passing through the first limiting ring and abutting against the first limiting ring at its bottom to complete the assembly. The sealing component 6 is made entirely of PP material.

[0026] In this embodiment, the bottom of the first limiting ring is provided with a flared portion 12 for guiding the flexible positioning ring 82. By providing the flared portion 12, the flexible positioning ring 82 can be deformed and guided when it is squeezed, which further facilitates assembly.

[0027] In this embodiment, the liquid outlet channel 4 has a narrowing section 13 with a gradually decreasing diameter near the outlet side. This structure allows the gap between the plug 7 and the inner wall of the liquid outlet channel 4 to gradually widen as the plug 7 is gradually pushed into the liquid outlet channel 4 when the pressing part 10 is pressed. This allows for adjustment of the pressing pressure to control the dispensing speed of the essence.

[0028] In this embodiment, a second limiting ring 14 is provided on the outer wall of the mating component 5, and the outer wall of the mating component 5 below the second limiting ring 14 is press-fitted with the inner wall of the bottle mouth 2. This structure facilitates the sealing assembly of the mating component 5 onto the bottle mouth 2 and ensures that the positions are consistent.

[0029] In this embodiment, the outer wall of the bottle mouth 2 is threadedly fitted with the bottle cap 15.

[0030] In this embodiment, an annular protrusion 16 is provided on the inner wall of the top of the bottle cap 15. When the bottle cap 15 is closed, the annular protrusion 16 abuts against the mating part 5 to seal the liquid outlet channel 4, and the pressing part 10 is located inside the annular protrusion 16. This structure can further increase the sealing of the outlet side of the liquid outlet channel 4 when the bottle cap 15 is screwed onto the bottle mouth 2, avoiding accidental leakage of the essence due to factors such as violent shaking.

[0031] In this embodiment, to prevent the pressing part 10 from being pressed after the bottle cap 15 is closed, the height of the annular protrusion 16 is higher than the distance of the pressing protrusion from the liquid outlet channel 4.

[0032] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
