[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection", etc. should be understood in a broad sense, for example, it can be a fixed connection (such as clamping, threaded connection, riveting, welding), or a detachable connection, or an integral connection; of course, it can also be a mechanical connection or an electrical connection; in addition, it can also be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The following are embodiments of the present application:

[0039] like Figure 1-12 As shown, a controlled amount smear packaging bottle comprises an outer cover 1, an inner cover 2, a liquid storage cover 3, an smearing device 4, an inner plug 5, and a bottle body 6. The inner cover 2 is fixedly connected to the outer cover 1, the inner cover 2 is threadedly connected to the bottle body 6, the inner plug 5 is inserted into the upper opening of the bottle body 6 and is clamped with the bottle body 6, the inner plug 5 is provided with a guide column 501 and an elastic body 502 integrally formed with the guide column 501, the smearing device 4 is sleeved on the elastic body 502, the liquid storage cover 3 is sleeved on the smearing device 4, the lower end of the liquid storage cover 3 is clamped with the inner plug 5 in a relatively rotatable manner, the outer peripheral wall of the guide column 501 is provided with at least one convex rail 5011 (preferably 3-5), and the inner cavity of the smearing device 4 is provided with support ribs 401 with the same number as the convex rails 5011. A second intercepting ring 403 is provided on the smearing device 4, and a second contact wall 301 is provided on the liquid storage cover 3.

[0040] As shown in Figures 9 and 10, when the inner cap 2 is unscrewed, the support rib 401 spirally rotates upward along the convex track 5011 until it passes the top position of the convex track 5011. At this time, the smearing device 4 also moves to the top position. At this position, the second intercepting ring 403 abuts against the second contact wall 301. The second intercepting ring 403, the liquid storage cap 3, and the inner plug 5 form a second chamber 8. When the bottle body 6 is inverted, a certain amount of liquid to be applied will be pre-accommodated in the second chamber 8.)

[0041] Furthermore, the number of the raised rails 5011 is preferably 2-4, and the upper end surface of the raised rail 5011 is inclined.

[0042] Furthermore, if Fig.11As shown, the smearing device 4 is provided with a first intercepting ring 402, the inner plug 5 is provided with a first contact wall 504, and an avoidance groove 5012 is provided between each convex rail 5011 on the outer peripheral wall of the guide column 501. When the smearing device 4 is pressed by the user, the support rib 401 will be forced to move downward and insert into the avoidance groove 5012 until it reaches the first position of the avoidance groove 5012. Even when the first intercepting ring 402 and the first contact wall 504 are against each other, the lower end of the support rib 401 is at the minimum position relative to the bottom end of the avoidance groove 5012. At this position, the first intercepting ring 402, the inner plug 5 and the liquid storage cover 3 are closed to form a first chamber 7. At this time, the first chamber 7 contains a single fixed volume of liquid to be applied.

[0043] like Fig. 9 As shown, the movement trajectory of the support rib 401 on the convex rail 5011 is as follows in chronological order: initial state a, when the inner cover 2 is unscrewed, the support rib 401 spirally rotates upward along the convex rail 5011 - state b, after the inner cover 2 is unscrewed, the lower end of the support rib 401 rotates upward over the top position of the convex rail 5011 - state c, after the application device 4 is pressed by the user, the support rib 401 is forced to move downward and insert into the avoidance groove 5012 - state d, the elastic body 502 recovers the compression deformation, and the support rib 401 is forced to move upward to the entrance of the avoidance groove 5012 - state e (same as initial state a).

[0044] Furthermore, a rotating tooth 404 is provided on the middle cylindrical surface of the coating device 4, and the liquid storage cover 3 is provided with at least two transmission ribs 302 distributed circumferentially around the rotating tooth 404. A protrusion 3021 is provided at the bottom of the transmission rib 302 to engage with the rotating tooth 404, so as to drive the coating device 4 to rotate when the liquid storage cover 3 is rotated.

[0045] like Figure 5 As shown, the rotating tooth 404 is relatively gentle along the tightening direction of the inner cover 2 (which may be counterclockwise, clockwise or other tightening directions), and is relatively steep along the unscrewing direction of the inner cover 2 (which may be counterclockwise, clockwise or other tightening directions). When the application device 4 is obstructed by the rotation, the transmission rib 302 can be elastically deformed and jump to the next rotating tooth 404.

[0046] Furthermore, the coating device 4 is provided with a coating head 405, the liquid storage cover 3 is provided with a liquid outlet 305, the coating head 405 passes through the liquid outlet 305 and blocks the liquid outlet 305, and at least two grooves 4051 are provided at the end of the coating head 405, such as Fig.11 As shown, when the coating head 405 is squeezed, the groove 4051 can be connected to the first chamber 7 in the liquid storage cover 3, so as to achieve the effect of squeezing out the liquid.

[0047] Furthermore, at least two baffles 304 (preferably 3-5) are integrally provided on the outer side of the liquid storage cover 3, and at least two convex strips 202 are provided on the inner wall of the inner cover 2. When the inner cover 2 is subjected to force when the user rotates it, the liquid storage cover 3 is driven to rotate by the mutual movement of the convex strips 202 and the baffles 304.

[0048] Furthermore, the liquid storage cover 3 is provided with a clamping groove 303, and a clamping ring 505 corresponding thereto is provided at the outer wall of the opening on the inner plug 5. After the liquid storage cover 3 is clamped with the inner plug 5, it can rotate relative to the inner plug 5.

[0049] Furthermore, the inner cover 2 is provided with a sealing ring 201 at the outer wall of the liquid outlet 305 corresponding to the liquid storage cover 3 , so as to strengthen the sealing of the liquid outlet 305 .

[0050] Furthermore, the inner plug 5 is open at the top and bottom, and at least one through hole 503 is provided at the bottom of the guide column 501 to facilitate the flow of liquid.

[0051] Usage method: The utility model provides a controlled-quantity smear packaging bottle. After the user unscrews the inner cover and the outer cover, the smear packaging bottle can be inverted and applied to the area to be applied. Since the liquid output is a set single-use amount, the user can squeeze the smear head toward the area to be applied to squeeze out the liquid until the set single-use amount is used up; then screw on the inner cover and the outer cover to end the use, and repeat the above-mentioned cap-unscrewing and inverted smearing process for the next use.

[0052] The utility model has the following beneficial effects:

[0053] First of all, the controlled-quantity smear packaging bottle controls the amount by switching the two intercepting rings up and down to isolate the liquid, which solves the problem of difficult-to-control usage in traditional packaging without adding some complicated and difficult-to-understand operations. The user can directly unscrew the lid and squeeze and apply it on the area to be applied to achieve the effect of controlled quantity. It is particularly suitable for application to areas with blind spots in the field of vision, such as scalp care, and can effectively avoid the problem of excessive use.

[0054] Secondly, compared with the existing traditional packaging that is divided into multiple pieces, the utility model integrates the applicator and the container into an integrated design, which has the beneficial effects of being easy to operate and carry, improving the convenience during the care process and improving the user's efficiency.

[0055] Finally, it should be noted that the above embodiments are only preferred embodiments of the present invention to illustrate the technical solution of the present invention, rather than limiting it, and certainly not limiting the patent scope of the present invention; although the present invention has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention; that is to say, any changes or embellishments made to the main design concept and spirit of the present invention that have no substantive significance, and the technical problems they solve are still consistent with the present invention, should be included in the protection scope of the present invention; in addition, the direct or indirect application of the technical solution of the present invention in other related technical fields is also included in the patent protection scope of the present invention.
