Description

Technical Field

[0001] This utility model relates to the field of massage bottle technology, and in particular to a ball bearing liquid storage bottle. Background Technology

[0002] As people's living standards improve, they are paying more and more attention to the health and appearance of their skin, leading to the increasingly widespread use of skincare products. Skincare products are usually liquid, requiring users to apply them to their skin. However, pouring the product from a container can easily result in too much being poured out, and applying it with fingers is often not evenly distributed.

[0003] In response to this, some manufacturers have introduced rollerball-type liquid bottles. A rollerball is installed at the mouth of the liquid bottle, and the rollerball fits the mouth of the bottle. The rotation of the rollerball carries the skin care product out of the bottle to help users apply the cosmetics to their skin. However, the rollerball of this product sometimes gets stuck, causing problems such as uneven liquid dispensing. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a ball bearing liquid storage bottle.

[0005] A ball bearing liquid storage bottle includes: a bottle body assembly having a receiving cavity, the top of the bottle body assembly having at least two liquid outlets, the two liquid outlets respectively communicating with the receiving cavity; a fixing member connected to the top of the bottle body assembly; and a ball bearing assembly including a first ball and a second ball, the first ball and the second ball respectively having a clearance fit with the two liquid outlets, and both being rotatably connected to the fixing member.

[0006] This design allows the internal cavity of the bottle assembly to hold skincare products such as serums, oils, and lotions. Two dispensing outlets connect to the cavity, allowing the products to flow outwards. When using the rollerball dispenser, the first and second rollerballs contact the skin, rotating to dispense the product evenly. Because the rollerball dispenser has at least two rollerballs, even if one becomes stuck, the other rollerball can continue to dispense evenly, preventing the problem of dispensing failure due to jamming. Furthermore, the spaced arrangement of the first and second rollerballs better conforms to non-flat areas of the body, such as the area around the eyes. When the bottle contains eye cream or other eye serums, the first and second rollerballs can conform to the contours of the eyes, allowing for better application.

[0007] In one embodiment, the fixing member has a first fixing groove and a second fixing groove, the first ball is installed in the first fixing groove, the second ball is installed in the second fixing groove, and the bottom of the first fixing groove and the bottom of the second fixing groove are both provided with the liquid outlet.

[0008] In one embodiment, the diameter of the opening of the first fixing groove is smaller than the diameter of the first ball, and the diameter of the opening of the second fixing groove is smaller than the diameter of the second ball.

[0009] In one embodiment, the opening of the first fixing groove extends radially inward and abuts against the first ball; the opening of the second fixing groove extends radially inward and abuts against the second ball.

[0010] In one embodiment, at least two ribs protrude radially inward from the opening of the first fixing groove, and the two ribs are spaced apart along the axial direction of the bottle body assembly; and / or,

[0011] At least two ribs are provided on the radial inner side of the opening of the second fixing groove, and the two ribs are spaced apart along the axial direction of the bottle body assembly.

[0012] In one embodiment, the bottom of the first fixing groove is provided with a step, the step being in clearance fit with the first ball, and the first ball being able to abut against the step in response to an external force; and / or,

[0013] The bottom of the second fixing groove has the step, the step is in clearance fit with the second ball, and the second ball can abut against the step in response to external force.

[0014] In one embodiment, the bottle assembly includes a body and a mounting base, the top of the body having an opening, the mounting base being installed in and sealing the opening, and the mounting base having the liquid outlet.

[0015] In one embodiment, the fastener is integrally formed with the mounting base.

[0016] In one embodiment, the ball bearing reservoir further includes a cap assembly, which includes an inner cap and an outer cap, the inner cap being connected to the inside of the outer cap and connected to the bottle body assembly.

[0017] In one embodiment, the cap assembly further includes a gasket that is mounted on the bottom of the inner cap and abuts against the ball bearing assembly.

[0018] Compared to existing technologies, this invention features at least two dispensing ports and at least a first and a second ball bearing on the bottle body. The two dispensing ports are connected to the receiving cavity, allowing skincare products to flow outwards. When using the ball bearing reservoir, the first and second ball bearings contact the skin, rotating to draw out the skincare product from the receiving cavity and achieve even dispensing. Because this invention provides a ball bearing reservoir with at least two ball bearings, even if one of the first or second ball bearings becomes stuck, the other ball bearing can still function normally to continue dispensing evenly. This avoids the problem of dispensing difficulties due to jamming, and the two-ball structure is suitable for more body parts. Attached Figure Description

[0028] Please see Figures 1-2 This utility model provides a ball bearing liquid storage bottle 100 with at least two balls, which makes the liquid dispensing of the ball bearing liquid storage bottle 100 more uniform and reduces the failure rate.

[0029] A ball bearing liquid storage bottle 100 includes a bottle body assembly 10, a fixing member 20, and a ball bearing assembly 30. The bottle body assembly 10 has a receiving cavity 11, and at least two liquid outlets 12 are opened on the top of the bottle body assembly 10, and the two liquid outlets 12 are respectively connected to the receiving cavity 11. The fixing member 20 is connected to the top of the bottle body assembly 10. The ball bearing assembly 30 includes a first ball bearing 31 and a second ball bearing 32, the first ball bearing 31 and the second ball bearing 32 are respectively clearance-fitted with the two liquid outlets 12, and are rotatably connected to the fixing member 20.

[0030] Thus, the internal cavity 11 of the bottle assembly 10 is used to hold skincare products, such as serums, essential oils, and lotions. Two dispensing ports 12 communicate with the cavity 11, allowing the skincare products to flow outwards. When using the ball bearing reservoir 100, the first ball 31 and the second ball 32 contact the skin. As the first ball 31 and the second ball 32 rotate, they draw out the skincare products from the cavity 11, achieving even dispensing. Because the ball bearing reservoir 100 provided by this invention has at least two balls, if one of the first ball 31 or the second ball 32 becomes accidentally stuck, the other ball can still function normally to continue dispensing evenly. Therefore, the problem of the ball bearing reservoir 100 failing to dispense liquid due to sticking is avoided.

[0031] Furthermore, the structure of the two rollers 31 and 32, which are spaced apart, fits better to parts of the human body that are not flat, such as the area around the eyes. When the bottle assembly 10 contains eye cream or other eye serums, the first roller 31 and the second roller 32 can fit the contour of the eyes, allowing the eye cream to be applied better to the area around the eyes.

[0032] The fixing member 20 has a first fixing groove 21 and a second fixing groove 22. The first ball bearing 31 is installed in the first fixing groove 21, and the second ball bearing 32 is installed in the second fixing groove 22. Both the bottom of the first fixing groove 21 and the bottom of the second fixing groove 22 are provided with liquid outlets 12. In this way, the first fixing groove 21 and the second fixing groove 22 provide space for the first ball bearing 31 and the second ball bearing 32 to be installed, and prevent the first ball bearing 31 and the second ball bearing 32 from falling off when rotating.

[0033] The diameter of the opening of the first fixing groove 21 is smaller than the diameter of the first ball 31, and the diameter of the opening of the second fixing groove 22 is smaller than the diameter of the second ball 32. In this way, the first ball 31 and the second ball 32 are further limited, and the openings abut against the first ball 31 and the second ball 32 to prevent them from loosening and falling off during frequent rotation and stress.

[0034] The opening of the first fixing groove 21 extends radially inward and abuts against the first ball bearing 31; the opening of the second fixing groove 22 extends radially inward and abuts against the second ball bearing 32. In other words, the first fixing groove 21 abuts against the first ball bearing 31 only through its opening, with a gap between the groove wall and the first ball bearing 31. This allows the skincare product to pass through the gap, and through the rotation of the first ball bearing 31, the product is evenly dispensed from the gap between the opening of the first fixing groove 21 and the abutment of the first ball bearing 31. The fit between the second fixing groove 22 and the second ball bearing 32 is similar and will not be described further here.

[0035] Understandably, in other embodiments, the first fixing groove 21 may not pass through the groove opening, but instead has a protruding abutment structure on the middle side wall of the groove that abuts against the first ball 31. This also allows the first ball 31 to rotate freely while discharging liquid evenly. Alternatively, it may directly abut against the first ball 31 through the groove wall for a sliding connection, rather than being limited to the above-mentioned abutment against the first ball 31 through the groove opening.

[0036] The first fixing groove 21 has at least two protruding ribs on its radially inner side at the opening, with the two ribs spaced apart along the axial direction of the bottle body assembly 10; and / or, the second fixing groove 22 has at least two protruding ribs on its radially inner side at the opening, with the two ribs spaced apart along the axial direction of the bottle body assembly 10. The two ribs improve the limiting effect between the first fixing groove 21 and the first ball 31, increasing the number of contact points, preferably line contact, resulting in more uniform liquid dispensing. The second fixing groove 22 also has two ribs at its opening to improve the limiting effect on the second ball 32.

[0037] Furthermore, the bottom of the first fixing groove 21 has a step 23, which is in clearance fit with the first ball bearing 31, and the first ball bearing 31 can abut against the step 23 in response to external force; and / or, the bottom of the second fixing groove 22 has a step 23, which is in clearance fit with the second ball bearing 32, and the second ball bearing 32 can abut against the step 23 in response to external force. Thus, the step 23 and the edge of the opening 131 of the liquid outlet 12 will form at least two line contact points with the first ball bearing 31 and the second ball bearing 32 respectively, thereby making the positioning of the first ball bearing 31 and the ball bearing more stable, the rotation smoother, and the liquid dispensing more even. When pressing without force, the first ball bearing 31 and the step 23, and the second ball bearing 32 and the step 23, are in clearance fit, allowing the skincare product to dispense smoothly. When pressing with more force, they abut against each other, making the positions of the first ball bearing 31 and the second ball bearing 32 more stable.

[0038] The bottle assembly 10 includes a body 13 and a mounting base 14. The top of the body 13 has an opening 131, and the mounting base 14 is installed in and seals the opening 131. The mounting base 14 has a liquid outlet 12. Thus, the mounting base 14 and the body 13 can be manufactured separately, and the body 13 and the mounting base 14 can be made of different materials. For example, the body 13 can be made of glass, and the mounting base 14 can be made of plastic. Glass has stable chemical properties and a more textured appearance, while the mounting base 14, since it needs to have a liquid outlet 12 and support the first ball bearing 31 and the second ball bearing 32, can improve the durability of the ball bearing liquid storage bottle 100 by using a more durable plastic.

[0039] For example, in this embodiment, the glass bottle is made of a dark-colored material to protect the skin care product contained in the receiving cavity 11.

[0040] Preferably, the fastener 20 is integrally formed with the mounting base 14, thereby simplifying the forming process and reducing the processing difficulty and cost.

[0041] The ball bearing reservoir 100 also includes a cap assembly 40, which includes an inner cap 42 and an outer cap 41. The inner cap 42 is connected to the inside of the outer cap 41 and is connected to the bottle body assembly 10. This combination of the inner cap 42 and the outer cap 41 increases the structural strength of the cap assembly 40, while the inner cap 42 provides limiting protection for the first and second ball bearings 31. The inner cap 42 is tightly connected to the bottle body assembly 10, improving the sealing performance of the accommodating cavity 11.

[0042] In this embodiment, the inner cap 42 is threadedly engaged with the bottle body assembly 10, i.e., the main body 13.

[0043] Preferably, the cap assembly 40 further includes a gasket 421, which is installed on the bottom of the inner cap 42 and abuts against the ball assembly 30. Thus, the gasket 421 can further provide a cushioning effect, protecting the first ball 31 and the second ball 32.

[0044] For example, in this embodiment, the first ball bearing 31 and the second ball bearing 32 are both configured as steel column structures with a diameter of 8mm. The first ball bearing 31 and the second ball bearing 32 are respectively installed at the middle position of the two liquid outlets 12. The liquid outlets 12 are all circular. The first ball bearing 31 and its corresponding liquid outlet 12 are coaxially arranged, and the second ball bearing 32 and its corresponding liquid outlet 12 are also coaxially arranged. With the center of the first ball bearing 31 extending horizontally and defining a reference surface, the straight-line perpendicular distances between the two protruding ribs at the first groove and the reference surface are 0.25mm-0.75mm and 1.85mm-2.55mm, respectively. The straight-line perpendicular distance between the upper side of the step 23 facing the bottle cap assembly 40 and the reference surface is 2.65mm-3.65mm. The straight-line perpendicular distance between the plane containing the edge of the opening 131 of the liquid outlet 12 and the reference surface is 3.53mm-4.03mm.

[0045] Compared to existing technologies, this invention provides at least two outlets 12 and at least a first ball bearing 31 and a second ball bearing 32 on the bottle body. The two outlets 12 are connected to the receiving cavity 11, allowing skincare products to flow outwards through them. When using the ball bearing reservoir 100, the first ball bearing 31 and the second ball bearing 32 contact the skin, rotating to draw out the skincare product from the receiving cavity 11 and achieve uniform dispensing. Because the ball bearing reservoir 100 provided by this invention has at least two balls, if one of the first ball bearing 31 or the second ball bearing 32 becomes stuck, the other ball bearing can still function normally to continue dispensing evenly. Therefore, it avoids the problem of the ball bearing reservoir 100 failing to dispense liquid due to sticking.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
