Description

Technical Field

[0001] This utility model relates to the field of vacuum bottle technology, specifically a vacuum bottle with an ultrasonically welded bottom cap. Background Technology

[0002] As is well known, vacuum bottles for cosmetics are an important packaging container widely used for the storage and distribution of liquid or cream products such as skin care products, serums, and lotions. Their main function is to isolate the contents from the outside air through a vacuum structure, preventing them from deteriorating due to oxidation, while providing a convenient press-type dispensing method to meet consumers' needs for product freshness and user experience.

[0003] The traditional connection method between vacuum bottles and the bottom cap may result in poor sealing, easily leading to air or liquid leakage, which affects the preservation of the contents. The connection between the cap and the bottle body usually relies on a simple snap-fit ​​structure, which is prone to loosening under external force, during transportation, storage, and user use, causing the contents to leak out or become contaminated. This risk is particularly prominent for cosmetics containing high-value ingredients. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4A vacuum bottle with an ultrasonically welded bottom cap includes a bottle body 1, a bottle bottom 2, a pressing head 3, a bottle cap 4, a locking device, and a guiding device. The bottom wall of the bottle body 1 is ultrasonically welded to the bottle bottom 2. The pressing head 3 is threaded onto the top of the bottle body 1. A fixing ring 5 is fixedly installed on the top of the bottle body 1. The fixing ring 5 and the bottle cap 4 are connected by the locking device. The locking device includes a groove 6, a bidirectional screw 7, a slider 8, a driven bevel gear 9, a driving bevel gear 10, a drive shaft 11, a clamping plate 12, a positioning block 13, and a positioning groove 14. The bottom wall of the bottle cap 4 has a cavity, and the top wall of the cavity has the groove 6. The bidirectional screw 7 is rotatably installed in the groove 6. The driven bevel gear 9 is sleeved in the middle, and the driving bevel gear 10 is meshed with the top of the driven bevel gear 9. The top of the driving bevel gear 10 passes through the top wall of the bottle cap 4 and is fitted with the drive shaft 11. The sliders 8 are threaded onto both ends of the bidirectional screw 7. The clamping plates 12 are fixedly installed on the top wall of the sliders 8. The positioning blocks 13 are installed on the corresponding side walls of the two sets of clamping plates 12. The positioning grooves 14 are opened on both ends of the fixing ring 5. The positioning grooves 14 and the positioning blocks 13 are adapted to each other. In this embodiment, the bottle body 1 and the bottle bottom 2 are aligned to ensure that the welding part is clean and free of impurities. The bottle bottom 2 is firmly connected to the bottom wall of the bottle body 1 using ultrasonic welding equipment. After welding is completed... First, check the sealing and strength of the welded parts to ensure there is no risk of leakage. Then, install the press head 3 on the top of the bottle body 1 via threads and tighten it to ensure a secure fixation. The fixing ring 5 is installed on the top wall of the bottle body 1 and positioned on the outer wall of the press head 3. When it is necessary to install and lock the bottle cap 4 to the bottle body 1, place the bottle cap 4 on top of the fixing ring 5, aligning the cavity at the bottom of the bottle cap 4 with the fixing ring 5, so that the bottle cap 4 covers the press head 3. Align the positioning block 13 and the positioning groove 14 through the guide device. Then, manually rotate the drive shaft 11. The drive shaft 11 drives the active bevel gear 10 to rotate. The active bevel gear 10 meshes with the driven bevel gear 9, causing the bidirectional screw 7 to rotate. The rotation of the bidirectional screw 7 pushes the sliders 8 on both sides to move towards each other. The sliders 8 drive the clamping plate 1. The positioning block 13 on the clamping plate 12 moves inward. When the clamping plate 12 contacts the outer wall of the fixing ring 5, the positioning block 13 is embedded in the positioning groove 14 on the fixing ring 5, completing the locking of the bottle cap 4. The locking device, through the design of the bidirectional screw 7, the slider 8 and the positioning block 13, achieves precise locking between the bottle cap 4 and the fixing ring 5. After the positioning block 13 is embedded in the positioning groove 14, the bottle cap 4 cannot be easily opened, ensuring the safety of the vacuum bottle during transportation or use. The locking device not only provides a physical locking function, but also enhances the connection strength between the bottle cap 4 and the bottle body 1, preventing the bottle cap 4 from falling off due to external force. It is suitable for various scenarios. When it is necessary to unlock the bottle cap 4 from the bottle body 1, the drive shaft 11 is rotated in the opposite direction, causing the bidirectional screw 7 to rotate in the opposite direction.The slider 8 moves the clamping plate 12 and its positioning block 13 outwards, causing the positioning block 13 to disengage from the positioning groove 14 on the fixing ring 5, at which point the bottle cap 4 can be easily removed.

[0025] Preferably, in this embodiment, the guiding device includes a fixing block 15, a guide strip 16, and a guide groove 17. The fixing blocks 15 are installed at both the front and rear ends of the cavity, and the guide strip 16 is installed at one corresponding end of each of the two sets of fixing blocks 15. The guide groove 17 is provided at both the front and rear ends of the fixing ring 5. The guide strip 16 and the guide groove 17 are slidably connected. When installing the bottle cap 4, the cavity of the bottle cap 4 is aligned with the fixing ring 5, and the guide strip 16 is aligned with the guide groove 17 on the fixing ring 5. Because the guide strip 16... The guide groove 17 is designed for sliding connection. This structure can guide the bottle cap 4 to quickly enter the correct position. As the bottle cap 4 moves downward, the guide bar 16 slides along the guide groove 17, further ensuring that the position between the bottle cap 4 and the fixing ring 5 is accurate. This sliding process is smooth and stable, avoiding jamming or damage caused by misalignment. When the bottle cap 4 completely covers the fixing ring 5, the guide bar 16 is fully embedded in the guide groove 17. At this time, the bottle cap 4 and the fixing ring 5 are precisely aligned, preparing for the operation of the subsequent locking device.

[0026] Preferably, in this embodiment, a knob 18 is installed at the top of the drive shaft 11. The knob 18 is designed to increase the operating area at the top of the drive shaft 11, making it easier for the user to rotate the drive shaft 11 by hand. Compared with directly rotating the thin drive shaft 11, the knob 18 provides a larger lever arm, reducing the force required for the user to operate.

[0027] Preferably, in this embodiment, the sidewall of the knob 18 is provided with an anti-slip strip 19 in a ring shape. The anti-slip strip 19 significantly improves the friction between the knob 18 and the finger by increasing the roughness of the contact surface, effectively preventing slippage.

[0028] Preferably, in this embodiment, the clamping plate 12 is arc-shaped. The arc-shaped design makes the contact area between the clamping plate 12 and the outer wall of the fixing ring 5 larger, and can better fit the outer wall of the fixing ring 5. It can also distribute pressure more evenly, thereby improving the stability and reliability during locking.

[0029] Preferably, in this embodiment, both the guide bar 16 and the guide groove 17 are semi-cylindrical designs. Due to the good fit of the semi-cylindrical structure, the gap between the guide bar 16 and the guide groove 17 is small, thereby reducing the shaking of the slider 8 during the movement and improving the overall accuracy.

[0030] Preferably, in this embodiment, both the positioning block 13 and the positioning groove 14 are cylindrical in design. The cylindrical structure has good impact resistance and is not easily dislodged or damaged when subjected to external vibration or impact, thus enhancing the reliability of the product.

[0031] Preferably, in this embodiment, the top wall of the bottle cap 4 is equipped with a rotation indicator 20. The two sets of indicator 20 are distinguished by color to clearly indicate the "locking" and "unlocking" directions. With clear directional indication, the user can accurately judge the rotation direction and avoid the bottle cap 4 failing to lock or being accidentally opened due to incorrect operation.
