Description

Technical Field

[0001] The utility model relates to the technical field of quantitative coating of liquid cosmetics, in particular to a quantitative coating cosmetic bottle. Background Art

[0002] Existing quantitatively coated cosmetic bottles generally use bottles with bottle caps, and the bottle is inverted or squeezed to allow the material to enter the silo and then reach the scalp through the discharge head. After the ball at the front of the discharge head contacts the scalp, it is squeezed backward to compress the spring, and a gap is formed between the ball and the head of the discharge tube, and the material flows out. Or the bottle is equipped with a pressure pump and a bottle cap, and the material is squeezed into the silo by pressing the pressure pump and then reaches the scalp through the discharge head. When in use, it is necessary to pull the cover upward to form a silo, and the cover is installed or pulled out through the limit assembly. Usually, when assembling the quantitatively coated cosmetic bottle in the prior art, the limit assembly needs to be assembled axially. Therefore, the resistance encountered when the cover is installed downward cannot be too large, otherwise it will affect the assembly. However, while ensuring the assembly requirements, the limit effect of the cover when it is pressed will be reduced. When the pressing pressure is large, the cover is prone to move, affecting the use. At the same time, when the force to pull the cover upward is large, it is also easy for the cover to move upward too much and detach from the bottle. Utility Model Content

[0003] The purpose of the utility model is to overcome the technical problems in the prior art that the cover of a quantitatively coated cosmetic bottle is easily moved downward due to a large pressing pressure when in use or is easily separated from the bottle body due to a large pulling force when being pulled out, and to provide a quantitatively coated cosmetic bottle, the cover of which is not easily moved downward due to a large pressing pressure when in use, and is not easily separated from the bottle body due to a large force when the cover is pulled out, and has strong stability during use and the pulling out process.

[0005] Optionally, when the first limiting protrusion is in the use position, the side that abuts against the axial groove wall of the second limiting groove is the first limiting surface, and the groove wall surface of the second limiting groove abutting against the first limiting surface is the second limiting surface, and both the first limiting surface and the second limiting surface are planes arranged perpendicular to the axis of the feeding end.

[0006] Optionally, the side of the second limiting protrusion that abuts against the axial groove wall of the second limiting groove when the second limiting protrusion is in the use position is a third limiting surface, and the groove wall surface of the second limiting groove abutting against the third limiting surface is a fourth limiting surface, and the third limiting surface and the fourth limiting surface are both planes arranged perpendicular to the axis of the feeding end.

[0007] Optionally, the mounting groove includes a retaining portion for retaining the first limiting protrusion, and the retaining portion is arranged corresponding to the initial position of the first limiting protrusion in the circumferential direction. When the first limiting protrusion is located in the retaining portion, it abuts against the groove wall surface of the mounting groove away from the opening of the cover body.

[0008] Optionally, the first limiting protrusion, the second limiting protrusion, the first limiting groove and the second limiting groove are all strip structures extended along the circumferential direction, the first limiting protrusion and the first limiting groove have the same length and width, and the first limiting protrusion and the second limiting groove have the same length.

[0009] Optionally, a groove wall surface of the installation groove arranged close to the first limiting groove and the second limiting groove in the circumferential direction is a first inclined surface, and the first inclined surface is a plane inclined toward the outer side of the installation groove.

[0010] Optionally, when the first limiting protrusion and the second limiting protrusion are located in the installation groove, the side of the first limiting protrusion facing the first inclined plane is the second inclined plane, and the side of the second limiting protrusion facing the first inclined plane is the third inclined plane, and the inclination direction of the second inclined plane and the third inclined plane is consistent with the inclination direction of the first inclined plane.

[0011] Optionally, a groove wall surface of the first limiting groove arranged axially close to the second limiting groove is a fourth inclined surface, and the fourth inclined surface is a plane inclined toward the outside of the first limiting groove.

[0012] Optionally, when the first limiting protrusion is located in the first limiting groove, a side facing the fourth inclined surface is a fifth inclined surface, and an inclination direction of the fifth inclined surface is consistent with an inclination direction of the fourth inclined surface.

[0013] Optionally, it also includes: a discharging head and a button; the discharging head is arranged on the outer end surface of the cover body, the discharging head includes a ball, a spring, a discharging tube and a limiting cylinder, the limiting cylinder is sleeved on the bottom of the discharging tube and connected to the outer end surface of the cover body, the ball is located at one end of the discharging tube close to the outlet, the spring is located in the discharging tube, the two ends of the spring are respectively connected to the ball and the bottom of the limiting cylinder, the silo, the limiting cylinder and the discharging tube are connected in sequence; the button is arranged at the end of the bottle body away from the feeding end, and the bottle body quantitatively transports the internal material from the feeding end to the silo by pressing the button.

[0014] According to the above technical solution, when the limiting assembly needs to be assembled, the first limiting protrusion and the second limiting protrusion first enter the installation groove from the axial direction. Since the bottom surface of the installation groove extends to the opening of the cover body, the first limiting protrusion and the second limiting protrusion can enter the installation groove from the axial direction without hindrance, and then enter the initial position by rotating the cover body, that is, the limiting assembly is assembled from the circumferential direction. Since there is no need to consider the axial assembly requirements of the limiting assembly, the limiting strength of the first limiting protrusion when pressing the cover body downward can be greatly improved. After the first limiting protrusion enters the use position, the second limiting groove clamps the first limiting protrusion and the second limiting protrusion in the axial direction. By increasing the limiting strength between the first limiting protrusion and the second limiting groove, the cover body is prevented from moving downward during use, thereby ensuring the stability of the use process. When the cover body is pulled, the first limiting protrusion enters the second limiting groove. At this time, if the first limiting protrusion is used to limit the position when pulling the cover body upward, the cover body may move too much and detach from the bottle body when the force is large. Since the second limiting protrusion always moves in the second limiting groove, the limiting strength can be set to be very large when the cover is pulled upward by the second limiting protrusion. After the second limiting protrusion enters the use position, the limiting strength between the second limiting protrusion and the second limiting groove is increased, so that the cover is not easy to separate from the bottle body during the pulling process, thereby ensuring the stability of the cover pulling process.

[0029] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0030] In the present utility model, unless otherwise stated, the directional words "axial, circumferential" used in the mounting groove 211, the first limiting groove 2121 and the second limiting groove 2123 are based on the orientation of the cover body 21, that is, the directional words "axial, circumferential" used in all components disposed on the cover body 21 are consistent with the cover body 21. The directional words "axial, circumferential" used in the first limiting protrusion 324 and the second limiting protrusion 325 are based on the orientation of the feeding end 32, that is, the directional words "axial, circumferential" used in all components disposed on the feeding end 32 are consistent with the feeding end 32. Since the cover body 21 and the feeding end 32 are adapted structures, the axial direction of the cover body 21 is consistent with the axial direction of the feeding end 32, and the circumferential direction of the cover body 21 is consistent with the circumferential direction of the feeding end 32, therefore, all the "axial, circumferential" used in the present utility model are clearly directed. The position word "initial position" used refers to the position of the cover 21 of the cosmetic bottle when it leaves the factory, and the position of the corresponding parts is also defined as the initial position. The position word "use position" used refers to the position of the cover 21 of the cosmetic bottle when it is in use, and the position of the corresponding parts is also defined as the use position. The position words "upper, middle, lower, top, bottom" etc. used are usually based on Figure 7 and Figure 8 As for the orientation shown, this orientation limitation is only for the convenience of describing the present invention, and does not indicate that the device or component must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as a limitation on the present invention. At the same time, the dynamic change words such as "movement, movement, pulling, and crossing" involved in the present invention are based on the relativity of movement, and are only for the convenience of describing the change in the positional relationship between two components, and do not have specific limitations. For example, when the cover 21 is pulled, the bottle body 3 may remain stationary and the cover 21 may be pulled upward, or the cover 21 may remain stationary and the bottle body 3 may be moved downward, so that the cover 21 is pulled relative to the bottle body 3. The above explanation also applies to the position change of other components, which may be the movement of the component itself or the movement of the component relative to another component.

[0031] The utility model provides a quantitative coating cosmetic bottle, such as Figure 2-8As shown, the quantitative coating cosmetic bottle includes: a bottle body 3, a cover body 21, a limiting assembly and a mounting groove 211; the bottle body 3 includes a bottle body 31 and a feeding end 32 located at one end of the bottle body 31, the cover body 21 is a cylindrical structure adapted to the feeding end 32, the cover body 21 is sleeved on the outside of the feeding end 32, the side walls of the cover body 21 and the feeding end 32 are limited by the limiting assembly, and a material bin 4 is formed between the cover body 21 and the feeding end 32 after the cover body 21 is pulled, and the material bin 4 is connected to the discharge port at the end of the feeding end 32; the limiting assembly includes a first limiting protrusion 324, a second limiting protrusion 325, a first limiting groove 2121 and a second limiting groove 2123, the first limiting protrusion 324 and the second limiting protrusion 325 are axially spaced apart on the side wall of the feeding end 32, and the first limiting groove 212 1 and the second limiting groove 2123 are arranged on the inner wall of the cover body 21 at intervals along the axial direction, the initial position of the first limiting protrusion 324 is located in the first limiting groove 2121, the initial position of the second limiting protrusion 325 is located in the second limiting groove 2123, and the use positions of the first limiting protrusion 324 and the second limiting protrusion 325 are respectively located at the two ends of the axial direction in the second limiting groove 2123; the installation groove 211 is arranged on the inner wall of the cover body 21, the installation groove 211 is located on one side of the first limiting groove 2121 and the second limiting groove 2123 in the circumferential direction, the groove bottom surface of the installation groove 211 extends to the opening of the cover body 21, and the first limiting protrusion 324 and the second limiting protrusion 325 enter the initial position from the circumference of the cover body 21 through the installation groove 211. Specifically, the feeding end 32 is arranged at the top of the bottle body 31, and the inner diameter of the cover body 21 is consistent with the outer diameter of the feeding end 32. like Figure 3 As shown, the discharge port of the feeding end 32 is a first discharge port 323 arranged on the discharge surface 322. A liquid storage cavity for accommodating the material body is arranged inside the bottle body 31, and the liquid storage cavity, the first discharge port 323, and the silo 4 are sequentially connected, so that when the cover body 21 is in the use position, the material body in the liquid storage cavity enters the silo 4 through the first discharge port 323. It should be noted that the "bottom" involved in the groove bottom surface is not within the scope of the above-mentioned directional word "bottom", and the groove is only defined as including a groove bottom surface and a groove wall surface arranged around the groove bottom surface. Figure 6 As shown, the installation groove 211 has three groove wall surfaces, and the first limiting groove 2121 and the second limiting groove 2123 each have four groove wall surfaces.

[0032] According to the above technical solution, when the limiting assembly needs to be assembled, the first limiting protrusion 324 and the second limiting protrusion 325 first enter the installation groove 211 from the axial direction. Since the bottom surface of the installation groove 211 extends to the opening of the cover body 21, the first limiting protrusion 324 and the second limiting protrusion 325 can enter the installation groove 211 from the axial direction without any hindrance, and then enter the initial position by rotating the cover body 21, that is, the limiting assembly is assembled from the circumferential direction. Since there is no need to consider the axial assembly requirements of the limiting assembly, the limiting strength of the first limiting protrusion 324 when the cover body 21 is pressed downward can be greatly improved. After the first limiting protrusion 324 enters the use position, the second limiting groove 2123 axially engages the first limiting protrusion 324 and the second limiting protrusion 325. By increasing the limiting strength between the first limiting protrusion 324 and the second limiting groove 2123, the cover body 21 is prevented from moving downward during use, thereby ensuring the stability of the use process. When the cover 21 is pulled, the first limiting protrusion 324 enters the second limiting groove 2123. At this time, if the first limiting protrusion 324 is used to limit the cover 21 when it is pulled upward, the cover 21 may move too much and separate from the bottle 3 if the force is strong. Since the second limiting protrusion 325 always moves in the second limiting groove 2123, the limiting strength can be set very high when the cover 21 is pulled upward by the second limiting protrusion 325. After the second limiting protrusion 325 enters the use position, the limiting strength between the second limiting protrusion 325 and the second limiting groove 2123 is increased, so that the cover 21 is not easy to separate from the bottle 3 during the pulling process, and the stability of the cover 21 pulling process is ensured.

[0033] Alternatively, if Figure 6 As shown, a first limiting beam 213 is provided between the mounting groove 211 and the first limiting groove 2121 and the second limiting groove 2123, and the first limiting protrusion 324 and the second limiting protrusion 325 enter their respective initial positions by crossing the first limiting beam 213. A second limiting beam 2122 is provided between the first limiting groove 2121 and the second limiting groove 2123. When the first limiting protrusion 324 enters the use position from the initial position, it needs to cross the second limiting beam 2122 to enter the second limiting groove 2123, and then abut against the second limiting beam 2122 for limiting. A third limiting beam 2124 is provided below the second limiting beam 2122, and the second limiting groove 2123 is located between the second limiting beam 2122 and the third limiting beam 2124. When the second limiting protrusion 325 is located in the use position, it abuts against the third limiting beam 2124 for limiting.

[0034] Optionally, a guide groove is provided below the third limiting beam 2124, and the bottom surface of the guide groove extends to the opening of the cover body 21. When the cover body 21 needs to be rotated so that the first limiting protrusion 324 and the second limiting protrusion 325 in the mounting groove 211 enter the initial position from the circumferential direction, the guide groove plays a guiding role, and the position of the guide groove can be determined from the opening of the cover body 21, and then the orientation of the first limiting groove 2121 and the second limiting groove 2123 can be determined to determine the rotation direction. The second limiting beam 2122, the third limiting beam 2124, the first limiting groove 2121, and the second limiting groove 2123 together constitute the limiting groove portion 212. Optionally, the mounting groove 211, the first limiting groove 2121, and the second limiting groove 2123 are all grooves formed by being recessed from the inner wall of the cover body 21 to the outer wall of the cover body 21.

[0035] Optionally, the limiting components are provided in two groups, and the two groups of limiting components are symmetrically arranged relative to the axis of the feeding end 32. It should be noted that, Figure 3 The first limiting protrusion 324 and the second limiting protrusion 325 shown in FIG. Figure 6 The first limiting groove 2121 and the second limiting groove 2123 shown in FIG. 2 are not matched. In fact, Figure 3 The first limiting protrusion 324 and the second limiting protrusion 325 on the other side not shown in the figure are connected with Figure 6 The first limiting groove 2121 and the second limiting groove 2123 are matched. In other embodiments, the limiting components can also be set as one group, three groups or more. At the same time, multiple limiting components can be evenly distributed along the circumference, or unevenly distributed.

[0036] Optionally, a set of limiting components includes a mounting slot 211 and a limiting slot portion 212. In other embodiments, a set of limiting components can also be configured such that one limiting slot portion 212 corresponds to two mounting slots 211, or one mounting slot 211 corresponds to two limiting slot portions 212, as long as the design concept of the utility model can be realized.

[0037] As an embodiment, the first limiting protrusion 324 abuts against the axial groove wall of the second limiting groove 2123 when the first limiting protrusion 324 is in the use position as the first limiting surface 3243, the groove wall of the second limiting groove 2123 abutting against the first limiting surface 3243 is the second limiting surface 21221, and the first limiting surface 3243 and the second limiting surface 21221 are both planes arranged perpendicular to the axis of the feeding end 32. That is, the surfaces of the first limiting protrusion 324 abutting against the second limiting beam 2122 when the first limiting protrusion 324 is in the use position are both straight surfaces. Such a setting can greatly improve the limiting effect between the first limiting protrusion 324 and the second limiting beam 2122, can greatly enhance the limiting strength when the cover body 21 is pressed, and avoid the cover body 21 from moving when it is pressed.

[0038] As an embodiment, the side of the second limiting protrusion 325 that abuts against the axial groove wall of the second limiting groove 2123 when the second limiting groove 2123 is in the use position is the third limiting surface 3252, and the groove wall surface of the second limiting groove 2123 that abuts against the third limiting surface 3252 is the fourth limiting surface 21241. The third limiting surface 3252 and the fourth limiting surface 21241 are both planes arranged perpendicular to the axis of the feeding end 32. That is, the surfaces of the second limiting protrusion 325 and the third limiting beam 2124 that abut against each other are both straight surfaces. Such a setting can greatly improve the limiting effect between the second limiting protrusion 325 and the third limiting beam 2124, and can greatly enhance the limiting strength when the cover body 21 is pulled, thereby avoiding the situation where the cover body 21 is easily separated from the bottle body 3 due to excessive movement during the pulling process.

[0039] As an embodiment, the mounting groove 211 includes a retaining portion for retaining the first limiting protrusion 324, and the retaining portion is arranged corresponding to the initial position of the first limiting protrusion 324 in the circumferential direction. When the first limiting protrusion 324 is located in the retaining portion, it abuts against the groove wall surface of the mounting groove 211 away from the opening end of the cover body 21. That is, the movement of the first limiting protrusion 324 and the second limiting protrusion 325 in the mounting groove 211 is axially limited by the groove wall surface at the top of the mounting groove 211. Such a design can make the first limiting protrusion 324 move to the top in the mounting groove 211, and then enter the initial position by rotating the cover body 21, without the need for additional limiting structure design. Optionally, the circumferential length of the first limiting protrusion 324 is consistent with the circumferential length of the mounting groove 211, so as to limit the circumferential direction.

[0040] As an embodiment, the first limiting protrusion 324, the second limiting protrusion 325, the first limiting groove 2121 and the second limiting groove 2123 are all strip structures extending along the circumferential direction, the first limiting protrusion 324 and the first limiting groove 2121 have the same length and width, and the first limiting protrusion 324 and the second limiting groove 2123 have the same length. That is, when the cover body 21 is in the initial position, the axial and circumferential limiting is performed by the cooperation of the first limiting protrusion 324 and the first limiting groove 2121. When the cover body 21 is in the use position, the circumferential limiting is performed by the cooperation of the first limiting protrusion 324 and the second limiting groove 2123, and the axial limiting is performed by the second limiting groove 2123 engaging the first limiting protrusion 324 and the second limiting protrusion 325. As another embodiment, when the cover body 21 is in the initial position, the axial limiting can also be performed by the first limiting protrusion 324 and the second limiting protrusion 325 engaging the first limiting beam 213.

[0041] Optionally, since the cosmetic bottle has a greater need for limiting when pressing the cover body 21, the first limiting protrusion 324 is longer and the second limiting protrusion 325 is shorter, and such a design is more convenient for installation and operation. As another embodiment, the length of the second limiting protrusion 325 can also be the same as the length of the first limiting protrusion 324 or longer than the length of the first limiting protrusion 324.

[0042] As an embodiment, the groove wall surface of the installation groove 211 disposed near the first limiting groove 2121 and the second limiting groove 2123 in the circumferential direction is a first inclined surface 2131, and the first inclined surface 2131 is a plane inclined toward the outside of the installation groove 211. That is, the surface of the first limiting beam 213 facing the inside of the installation groove 211 is an inclined surface. Such a design is used to enable the first limiting protrusion 324 and the second limiting protrusion 325 to cross the first limiting beam 213 through the inclined surface and enter the initial position.

[0043] As an embodiment, when the first limiting protrusion 324 and the second limiting protrusion 325 are located in the installation groove 211, the side of the first limiting protrusion 324 facing the first inclined surface 2131 is the second inclined surface 3242, and the side of the second limiting protrusion 325 facing the first inclined surface 2131 is the third inclined surface 3251, and the inclination direction of the second inclined surface 3242 and the third inclined surface 3251 is consistent with the inclination direction of the first inclined surface 2131. That is, when located in the installation groove 211, the first limiting protrusion 324 and the second limiting protrusion 325 are both inclined surfaces for contacting the first limiting beam 213. Such a design can make it easier for the first limiting protrusion 324 and the second limiting protrusion 325 to cross the first limiting beam 213 and enter their respective initial positions when the cover body 21 rotates.

[0044] As an embodiment, the groove wall surface of the first limiting groove 2121 arranged axially close to the second limiting groove 2123 is a fourth inclined surface 21222, and the fourth inclined surface 21222 is a plane inclined toward the outside of the first limiting groove 2121. That is, the surface of the second limiting beam 2122 facing the inside of the first limiting groove 2121 is an inclined surface. Such a design is used to enable the first limiting protrusion 324 to cross the second limiting beam 2122 through the inclined surface and enter the second limiting groove 2123.

[0045] As an embodiment, when the first limiting protrusion 324 is located in the first limiting groove 2121, the side facing the fourth inclined surface 21222 is the fifth inclined surface 3241, and the inclined direction of the fifth inclined surface 3241 is consistent with the inclined direction of the fourth inclined surface 21222. That is, when the first limiting protrusion 324 is located in the first limiting groove 2121, the side in contact with the second limiting beam 2122 is the inclined surface. Such a design enables the first limiting protrusion 324 to more easily cross the second limiting beam 2122 and enter the second limiting groove 2123 during the process of the cover body 21 being pulled.

[0046] As an implementation method, Figure 1-2 and Figure 7-9 As shown, the quantitative coating cosmetic bottle also includes: a discharge head 22 and a button 33; the discharge head 22 is arranged on the outer end surface of the cover body 21, the discharge head 22 includes a ball 221, a spring 224, a discharge pipe 222 and a limiting cylinder 223, the limiting cylinder 223 is sleeved on the bottom of the discharge pipe 222 and connected to the outer end surface of the cover body 21, the ball 221 is located at one end of the discharge pipe 222 close to the outlet, the spring 224 is located in the discharge pipe 222, the two ends of the spring 224 are respectively connected to the ball 221 and the bottom of the limiting cylinder 223, the silo 4, the limiting cylinder 223, and the discharge pipe 222 are connected in sequence; the button 33 is arranged at one end of the bottle body 3 away from the feeding end 32, and the bottle body 3 quantitatively transports the internal material from the feeding end 32 to the silo 4 by pressing the button 33. The discharge head 22 and the cover body 21 together form the liquid discharge portion 2. Figure 6 and Fig. 9 As shown, the end surface of the cover body 21 is provided with a second discharge port 214, and the number of the second discharge ports 214 is consistent with the number of the discharge heads 22 and is arranged one by one. Correspondingly, the bottom of the limiting cylinder 223 is provided with a third discharge port 2231 connected to the second discharge port 214, and the third discharge port 2231 is also connected to the bottom opening of the discharge pipe 222, and the caliber of the third discharge port 2231 is smaller than the caliber of the bottom opening of the discharge pipe 222. During installation, the top of the spring 224 is connected to the ball 221, and the bottom is connected to the limiting cylinder 223, and then installed from the bottom opening of the discharge pipe 222, and finally the limiting cylinder 223 is sleeved on the outside of the bottom of the discharge pipe 222. When the cover body 21 is partially pulled out and is in the use position, the liquid storage cavity, the first discharge port 323, the silo 4, the second discharge port 214, the third discharge port 2231, and the discharge pipe 222 are connected in sequence.

[0047] Optionally, the number of the discharge heads 22 is six, and the six discharge heads 22 are evenly distributed. As other embodiments, the number of the discharge heads 22 can also be one, two, or other numbers. The multiple discharge heads 22 can also be unevenly distributed.

[0048] Alternatively, if Figure 1 and Figure 2 As shown, the quantitative coating cosmetic bottle further includes a bottle cap 1, which is disposed on the outside of the cover body 21 and engages with a limiting portion 321 disposed at the connection between the feeding end 32 and the bottle body 31. Specifically, the bottle cap 1 abuts against the end face of the limiting portion 321 with a larger outer diameter, and the cover body 21 abuts against the end face of the limiting portion 321 with a smaller outer diameter when the cover body 21 is in the initial position. Figure 3 As shown, the end surface of the limiting portion 321 with a smaller outer diameter is located above the end surface with a larger outer diameter, and the limiting portion 321 is an annular structure with a stepped cross-section.

[0049] Working principle:

[0050] When the cover 21 and the bottle body 3 need to be assembled, the first limiting protrusion 324 and the second limiting protrusion 325 are made to enter the installation groove 211 from the axial direction. When the first limiting protrusion 324 moves to abut against the groove wall surface at the top of the installation groove 211, the cover 21 is rotated in the direction of the guide groove, so that the first limiting protrusion 324 and the second limiting protrusion 325 respectively cross the first limiting beam 213 and enter their respective initial positions. The first limiting protrusion 324 enters the first limiting groove 2121, and the second limiting protrusion 325 enters the corresponding position in the second limiting groove 2123. At this time, the cover 21 is in the initial position, and the cover 21 and the feeding end 32 are limited in the axial and circumferential directions by the cooperation between the first limiting protrusion 324 and the first limiting groove 2121, and then the bottle cap 1 is covered to complete the assembly of the cosmetic bottle in the factory state.

[0051] When the cosmetic bottle needs to be used, the bottle cap 1 is opened, and then the cover body 21 is pulled upward, so that the cover body 21 moves upward a certain distance, and a material bin 4 is formed between the cover body 21 and the feeding end 32. Accordingly, the first limiting protrusion 324 crosses the second limiting beam 2122 and enters the second limiting groove 2123 and abuts against the second limiting beam 2122, and the second limiting protrusion 325 moves downward in the second limiting groove 2123 to a position abutting against the third limiting beam 2124. At this time, the cover body 21 is in the use position, and the cover body 21 and the feeding end 32 are circumferentially limited by the cooperation of the first limiting protrusion 324 and the second limiting groove 2123, and the second limiting groove 2123 is axially engaged with the first limiting protrusion 324 and the second limiting protrusion 325 for axial limitation.

[0052] When in use, aim the discharge head 22 at the part that needs to be coated, such as the skin of the head (or the skin of other parts), and convey the material inside the bottle body 3 from the feeding end 32 to the silo 4 by pressing the button 33. The material then enters the discharge pipe 222 from the silo 4, and then presses the skin through the discharge head 22 to form a gap between the ball 221 and the discharge pipe 222, and the material flows into the skin from the gap for coating and massage.
