Description

Technical Field

[0001] This utility model relates to the field of ball bearing bottle technology, and in particular to a ball bearing bottle with recirculation capability. Background Technology

[0002] Rollerball bottles are widely used in cosmetics such as essential oils. As shown in the patent application number CN202020772645.8, it includes a bottle body, an inner stopper and a roller. The inner stopper is installed at the upper end of the bottle body, and the roller is connected to the upper side of the inner stopper. When in use, the rollerball bottle is inverted, and after the roller rolls, the cosmetic in the bottle is applied to the skin.

[0003] Existing rollerball bottles, especially those used for essential oils, are very small, resulting in a small bottle opening. The cosmetics inside are somewhat sticky, and when used upside down, they move towards the bottle opening under gravity, creating negative pressure at the top of the bottle. This prevents the cosmetics from moving further down to the opening. In practice, it is often necessary to manually shake the rollerball bottle downwards to use inertia to help the cosmetics move to the opening and contact the roller before use, which is not very convenient. Utility Model Content

[0004] To address the drawback of existing roller ball bottles where a negative pressure zone easily forms at the top when inverted, preventing cosmetics from moving downwards, this invention proposes a roller ball bottle that allows outside air to be introduced to the top of the bottle via a return air pipe, preventing the formation of a negative pressure zone and enabling cosmetics to move smoothly downwards.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A ball bearing bottle with venting capability includes a bottle body, an inner stopper, a bottle cap, and a ball bearing. The inner stopper has a minimum inner diameter of d1, which is less than or equal to 2 cm. The inner stopper is installed in the bottle mouth of the bottle body. An installation groove is provided at the upper end of the inner stopper, and the ball bearing is placed in the installation groove. The bottle cap covers the upper end of the inner stopper and abuts against the upper side of the ball bearing. There is a gap between the ball bearing and the side wall of the installation groove. The ball bearing bottle also includes a venting pipe. The upper end of the venting pipe abuts against the lower side of the ball bearing and is fixedly connected to the bottle mouth of the bottle body. The lower end of the venting pipe is close to the bottom of the bottle body.

[0007] With the above settings, firstly, when the inverted ball bearing bottle is used, the vent pipe allows outside air to enter the bottle, preventing negative pressure from being generated inside the bottle and allowing the cosmetics inside the bottle to move smoothly downwards; secondly, the bottle cap seals the upper end of the vent pipe, preventing the cosmetics inside the bottle from entering the vent pipe from the lower end.

[0008] Furthermore, the distance from the lower end of the return pipe to the bottom of the bottle is d2, where d2 is less than or equal to 1 cm.

[0009] Furthermore, the outer diameter of the return pipe is d3, the inner diameter of the return pipe is d4, d3 / d1<50%, and d4 / d1>20%.

[0010] The above settings further facilitate the downward movement of cosmetics.

[0011] Furthermore, the inner plug includes an insertion section and a ball-filling section. The insertion section is vertically inserted into the bottle mouth of the bottle body, and the ball-filling section is vertically fixedly connected to the upper end of the insertion section. An installation groove is provided on the ball-filling section. The outer diameter of the ball-filling section is larger than the outer diameter of the insertion section, and the lower end of the ball-filling section abuts against the bottle mouth of the bottle body.

[0012] Furthermore, the bottle body has external threads on the outside of the bottle opening, and the bottle cap is threadedly connected to the bottle opening.

[0013] Furthermore, the upper end of the return gas pipe is coaxially and fixedly connected to the bottle mouth of the bottle body via a connecting rod.

[0014] Furthermore, the number of connecting rods can be set to three or one. Attached Figure Description

[0020] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] like Figures 1 to 5 As shown, a ball bearing bottle with venting capability includes a bottle body 3, an inner plug 4, a bottle cap 5, and a ball bearing 6. The inner plug 4 has a minimum inner diameter of d1, which is less than or equal to 2 cm. The inner plug 4 is installed in the bottle mouth of the bottle body 3. An installation groove 7 is provided at the upper end of the inner plug 4. The ball bearing 6 is placed in the installation groove 7. The bottle cap 5 covers the upper end of the inner plug 4 and abuts against the upper side of the ball bearing 6. There is a gap between the ball bearing 6 and the side wall of the installation groove 7. The ball bearing bottle also includes a venting pipe 8. The upper end of the venting pipe 8 abuts against the lower side of the ball bearing 6 and is fixedly connected to the bottle mouth of the bottle body 3. The lower end of the venting pipe 8 is close to the bottom of the bottle body 3.

[0022] With the above settings, firstly, when the inverted ball bearing bottle is used, the vent pipe 8 allows outside air to enter the bottle body 3, preventing negative pressure from being generated in the bottle body 3, and allowing the cosmetics in the bottle body 3 to move smoothly downwards; secondly, the bottle cap 5 blocks the upper end of the vent pipe 8, preventing the cosmetics in the bottle body 3 from entering the vent pipe 8 from the lower end of the vent pipe 8.

[0023] The maximum outer diameter of the bottle body 3 in this application is less than 5 cm, and the minimum inner diameter of the inner stopper 4 is less than or equal to 2 cm. The rollerball bottle has a small volume and is mainly suitable for cosmetics such as essential oils in small quantities. Due to the small volume of the bottle body 3, when the cosmetic has viscosity, the cosmetic in the bottle body 3 is less likely to fall out. The inner stopper 4 is a tubular structure running vertically through the bottle, with its lower end inserted into the bottle opening. Figure 2 As shown, the upper end of the inner plug 4 is flared to form a mounting groove 7. The opening of the mounting groove 7 is slightly concave to prevent the ball bearing 6 from falling out of the mounting groove 7. The bottom of the mounting groove 7 is provided with an annular support surface that abuts against the lower side of the ball bearing 6 to seal the inner plug 4 and prevent cosmetics in the bottle 3 from leaking out. The ball bearing 6 abuts against the upper end of the return air pipe 8 to seal the upper end of the return air pipe 8, which can prevent cosmetics in the bottle 3 from entering the return air pipe 8 from the lower end, thereby preventing the return air pipe 8 from becoming blocked. In use, if... Figure 3 As shown, after removing the cap 5 and inverting the bottle 3, the ball bearing 6 moves downward under gravity and disengages from the vent pipe 8. When the cosmetics in the bottle 3 move downward under gravity, outside air can enter the upper part of the bottle 3 through the lower end of the inner stopper 4 and the vent pipe 8, preventing the formation of a negative pressure zone at the upper part of the bottle 3 due to the downward movement of the cosmetics. This ensures that the air pressure inside and outside the bottle 3 is consistent, allowing the cosmetics in the bottle 3 to move smoothly downward under gravity into the inner stopper 4 and contact the upper side of the ball bearing 6. When using the bottle upside down, users do not need to shake the ball bearing bottle, making it more convenient to use.

[0024] As one implementation method, the distance from the lower end of the return pipe 8 to the bottom of the bottle body 3 is d2, where d2 is less than or equal to 1cm.

[0025] The distance from the lower end of the return gas pipe 8 to the bottom of the bottle body 3 is specifically 8mm. When the bottle body 3 is used upside down, the outside gas can smoothly reach the upper end of the bottle body 3.

[0026] As one implementation method, the outer diameter of the return air pipe 8 is d3, the inner diameter of the return air pipe 8 is d4, d3 / d1<50%, and d4 / d1>20%.

[0027] The above settings further facilitate the downward movement of cosmetics.

[0028] In this application, d3 / d1 = 45% and d4 / d1 = 25%. On the one hand, the gap between the outer side of the return air pipe 8 and the inner plug 4 is large enough to facilitate the downward movement of cosmetics through the inner plug 4. On the other hand, the channel inside the return air pipe 8 is relatively large to facilitate the return of air.

[0029] As one implementation, the inner plug 4 includes an insertion section 41 and a ball-filling section 42. The insertion section 41 is vertically inserted into the bottle mouth of the bottle body 3, and the ball-filling section 42 is vertically fixedly connected to the upper end of the insertion section 41. The mounting groove 7 is provided on the ball-filling section 42. The outer diameter of the ball-filling section 42 is larger than the outer diameter of the insertion section 41, and the lower end of the ball-filling section 42 abuts against the bottle mouth of the bottle body 3.

[0030] The insertion section 41 and the ball-filling section 42 of this application are integrally formed. The outer diameter of the ball-filling section 42 is larger than that of the insertion section 41, which facilitates the setting of the installation groove 7 in the ball-filling section 42. A conical surface is provided on the lower outer periphery of the insertion section 41 to facilitate insertion into the bottle mouth.

[0031] As one implementation method, the bottle body 3 has an external thread on the outside of the bottle opening, and the bottle cap 5 is threadedly connected to the bottle opening of the bottle body 3.

[0032] As one implementation method, the upper end of the return air pipe 8 is coaxially and fixedly connected to the bottle mouth of the bottle body 3 via the connecting rod 9.

[0033] As one implementation, the number of connecting rods 9 can be set to three or one.

[0034] like Figure 4 As shown, when three connecting rods 9 are provided in this application, the three connecting rods 9 are evenly arranged around the air pipe 8; in another embodiment, as... Figure 5 As shown, the connecting rod 9 is set as one, which makes the space between the inner plug 4 and the return air pipe 8 larger, which is more conducive to the downward movement of cosmetics.

[0035] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
