Description

Technical Field

[0001] This utility model relates to the field of container technology, and more specifically, to a rotating inner plug and a container bottle. Background Technology

[0002] Currently, consumers require different dispensing volumes when using liquid cosmetics such as serums and moisturizing oils, depending on their specific needs. A larger dispensing volume is needed for applications like wet compresses, while a smaller volume is required for everyday use. A single container and inner stopper dispensing port cannot effectively adjust the dispensing volume, while designs using two or more inner stoppers are more complex and costly. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a rotating inner plug that can achieve different discharge volumes by adjusting the size of the discharge port. The inner plug includes an inner plug body and an inner plug cover. The inner plug cover includes a top wall with a discharge pipe located in the center. The discharge pipe extends vertically through the top wall, and two first through holes are formed at the bottom of the discharge pipe. The inner plug body includes a top plate with a recessed receiving tube located in the center. Two centrally symmetrical second through holes are formed at the bottom of the recessed receiving tube. The bottom of the discharge pipe is located on the bottom of the recessed receiving tube. The inner plug cover can rotate relative to the inner plug body, thereby changing the overlap area of ​​the first and second through holes.

[0004] Furthermore, the first through hole and the second through hole are fan-shaped holes.

[0005] Furthermore, the two first through holes are centrally symmetrical, and the two second through holes are centrally symmetrical.

[0006] Furthermore, the outer periphery of the top wall is provided with a downwardly extending outer cylindrical wall, and the discharge pipe is provided with a protruding ring on the lower outer periphery of the top wall. A positioning groove is formed between the protruding ring and the outer cylindrical wall, and the lower ends of the protruding ring and the outer cylindrical wall abut against the upper end of the top plate. The upper end of the top plate is also provided with an upwardly extending positioning ring, which is located in the positioning groove.

[0007] Furthermore, the inner circumference of the outer cylindrical wall is provided with a groove extending in a partial circumferential direction, and the outer circumference of the positioning ring is provided with a protrusion extending in a partial circumferential direction. The protrusion is embedded in the groove, and the extension length of the protrusion is less than the extension length of the groove. When the inner plug cover rotates relative to the inner plug body, the protrusion is limited by the two ends of the groove, thereby limiting the rotation angle.

[0008] Furthermore, the inner circumference of the outer cylindrical wall is provided with grooves evenly distributed in the circumferential direction, and correspondingly, the outer circumference of the positioning ring is provided with protrusions evenly distributed in the circumferential direction. The protrusions are respectively embedded in the grooves, thereby forming rotational damping when the inner plug cover rotates relative to the inner plug body.

[0009] Furthermore, anti-slip teeth are provided on the outer periphery of the outer cylindrical wall.

[0010] This utility model also provides a container bottle, including a bottle body, a bottle cap and the aforementioned inner plug. The upper part of the bottle body is provided with a bottle mouth, and the bottom of the top plate of the inner plug body is also provided with a downwardly extending annular inner plug wall. The annular inner plug wall is inserted into the bottle mouth and is interference-fitted, threaded, or snap-fitted with the bottle mouth.

[0011] Furthermore, the top of the bottle cap is provided with a downwardly protruding plug, which is inserted into the outlet of the discharge pipe to seal the discharge pipe.

[0012] Furthermore, the top of the bottle cap is provided with a downwardly extending annular cylinder, which forms a threaded fit with the outer wall of the bottle mouth, thereby sealing the bottle cap with the bottle body.

[0013] This invention adjusts the liquid output by rotating the inner plug cap relative to the inner plug body, thereby changing the overlap area between the first and second through holes. Compared to existing complex inner plug designs, this invention has a simple structure and is easy to use. Attached Figure Description

[0020] See Figures 1-5The rotating inner plug of this utility model includes an inner plug body 1 and an inner plug cover 2. The inner plug cover 2 includes a top wall 21, and a discharge pipe 22 is provided in the middle of the top wall 21. The discharge pipe 22 extends vertically through the top wall 21, and two first through holes 221 are provided at the bottom of the discharge pipe 22.

[0021] The inner plug body 1 includes a top plate portion 11, with a recessed receiving tube 12 disposed in the middle of the top plate portion 11. Two second through holes 121 are formed at the bottom of the recessed receiving tube 12. The bottom of the discharge pipe 22 is located on the bottom of the recessed receiving tube 12. The inner plug cover 2 can rotate relative to the inner plug body 1, thereby changing the overlap area of ​​the first through hole 221 and the second through hole 121. Preferably, both the first and second through holes are fan-shaped and centrally symmetrically distributed. Those skilled in the art will understand that arc-shaped through holes extending circumferentially can also achieve the effect of changing the overlap area during rotation.

[0022] To ensure smooth rotation between the inner plug body 1 and the inner plug cover 2, a downwardly extending outer cylindrical wall 23 is provided on the outer periphery of the top wall 21. A protruding ring 222 is provided on the lower outer periphery of the discharge pipe 22 located on the top wall 21. A positioning groove 24 is formed between the protruding ring 222 and the outer cylindrical wall 23. The lower ends of the protruding ring 222 and the outer cylindrical wall 23 abut against the upper end of the top plate portion 11. An upwardly extending positioning ring 111 is also provided on the upper end of the top plate portion 11, and the positioning ring 111 is located within the positioning groove 24. Preferably, the top wall 21, the discharge pipe 22, the protruding ring 222, and the outer cylindrical wall 23 are integrally formed.

[0023] Furthermore, the inner circumference of the outer cylindrical wall 23 is provided with a groove 231 extending in a partial circumferential direction, and the outer circumference of the positioning ring 111 is provided with a protrusion 112 extending in a partial circumferential direction. The protrusion 112 is embedded in the groove 231, and the extension length of the protrusion 112 is less than the extension length of the groove 231. When the inner plug cover 2 rotates relative to the inner plug body 1, the protrusion 112 is limited by the two ends of the groove 231, thereby limiting the rotation angle.

[0024] As an alternative to the slots 231 and the protrusions 112, the inner circumference of the outer cylindrical wall 23 is provided with grooves evenly distributed circumferentially. Correspondingly, the outer circumference of the positioning ring 111 is provided with protrusions evenly distributed circumferentially. The protrusions are respectively embedded in the grooves, thereby forming rotational damping when the inner plug cover 2 rotates relative to the inner plug body 1. Those skilled in the art will understand that, since the outer cylindrical wall and the positioning ring 111 have a certain height, the grooves and protrusions can be added on the basis of the slots 231 and the protrusions 112. The grooves / protrusions and the slots / protrusions are at different heights, thereby limiting the rotation angle on the one hand and forming rotational damping on the other.

[0025] Furthermore, anti-slip teeth 232 are provided on the outer periphery of the outer cylindrical wall 23 to facilitate the user to rotate the inner plug 2.

[0026] See Figures 3-6 The container includes a bottle body 31 and a bottle cap 32. The upper part of the bottle body is provided with a bottle mouth 33. At the bottom of the top plate portion 11 of the inner stopper body 1, there is also a downwardly extending annular inner stopper wall 13. The annular inner stopper wall 13 is inserted into the bottle mouth 33 to form an interference fit, a threaded connection, or a snap-fit ​​connection. The top of the bottle cap 32 is also provided with a downwardly protruding cap plug 34. The cap plug 34 is inserted into the outlet of the discharge pipe 22, thereby sealing the discharge pipe 22.

[0027] Furthermore, the top of the bottle cap 32 is provided with a downwardly extending annular cylinder 35, which forms a threaded fit with the outer wall of the bottle mouth 33, thereby sealing the bottle cap 32 with the bottle body 31.

[0028] In use, the bottle cap 32 is opened, the stopper 34 disengages from the discharge pipe 22, and the inner stopper 2 is rotated to change the overlap area between the first through hole 221 and the second through hole 121, thereby adjusting the liquid output. Compared with the existing complex inner stopper design, the structure is simple and easy to use.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
