[0025] The following is combined with Figure 1-5 This application is described in further detail.

[0026] Embodiment 1: This embodiment of the present application discloses a push-type cosmetic bottle. Figure 1 and Figure 2 The push-type cosmetic bottle includes a bottle body 1, a push head 2, and an inner liner bottle 3. The push head 2 is sleeved at the bottle mouth of the bottle body 1 and the push head 2 is threadedly mounted on the bottle body 1. The inner liner bottle 3 is threadedly mounted on the bottom of the push head 2 and inserted into the bottle body 1. The inner liner bottle 3 contains cosmetics. When the cosmetics in the inner liner bottle 3 are used up, the inner liner bottle 3 can be directly removed and thrown away and replaced with a new inner liner bottle 3, thereby reducing resource waste.

[0027] Reference Figure 1 and Figure 2 The inside of the pressing head 2 is provided with a vacuum pressing pump 21, and the cosmetics in the inner liner bottle 3 can be extracted by the vacuum pressing pump 21. The bottom of the pressing head 2 is integrally formed with a plug sleeve 22, which is connected to the pressing pump, and the plug sleeve 22 is inserted into the inner liner bottle 3 from the bottle mouth of the inner liner bottle 3. The plug sleeve 22 is provided with an external thread, and the bottle mouth of the inner liner bottle 3 is provided with an internal thread. After the bottle mouth of the inner liner bottle 3 is sleeved on the plug sleeve 22, the thread is installed on the pressing head 2.

[0028] Reference Figure 1 and Figure 2 The inner bottle 3 is provided with a vacuum piston 31. After the pressing head 2 is squeezed by the pressing pump, the inner bottle 3 forms an air pressure difference with the outside under the action of the vacuum piston 31. After the pressing head 2 is released, the cosmetics in the inner bottle 3 will be discharged from the bottle body 1 through the plug-in sleeve 22 under the action of the air pressure difference for use. Under the action of the vacuum piston 31 and the vacuum pressing pump 21, even if the cosmetic bottle is placed upside down, the cosmetics in the inner bottle 3 can be squeezed out under the action of the air pressure difference.

[0029] In addition, a sealing ring groove 32 is provided at the top of the mouth of the inner bottle 3, and a sealing gasket 33 is installed in the sealing ring groove 32. The side of the sealing gasket 33 that is away from the bottom of the sealing ring groove 32 protrudes out of the sealing groove. When the inner bottle 3 is tightened on the plug-in sleeve 22, the side of the sealing gasket 33 that is away from the sealing ring groove 32 will be pressed against the pressing head 2, thereby improving the sealing between the inner bottle 3 and the pressing head 2, so that the cosmetics in the inner bottle 3 are not easy to leak out from the gap between the mouth of the inner bottle 3 and the pressing head 2.

[0030] The implementation principle of a press-type cosmetic bottle in an embodiment of the present application is as follows: some people often go out and always carry large bottles of cosmetics when going out, so they put the cosmetics in the large bottles into the smaller inner bottle 3. When the cosmetic bottles in the inner bottle 3 are used up, the press head 2 is unscrewed from the bottle body 1, and the inner bottle 3 is pulled out from the inside of the bottle body 1, and then the inner bottle 3 is unscrewed from the press head 2 and thrown away, and then the same cosmetics or different cosmetics are poured from the large bottle into the new inner bottle 3 and the new inner bottle 3 containing cosmetics is installed on the press head 2, and finally the press head 2 is installed on the bottle body 1.

[0031] Example 2: Reference Figure 3 and Figure 4 The difference between this embodiment and the first embodiment is that: a convex ring 23 is integrally formed at the bottom of the pressing head 2, the plug-in sleeve 22 is located inside the convex ring 23, and the central axis of the convex ring 23 coincides with the central axis of the plug-in sleeve 22. The mouth of the inner liner bottle 3 is located between the convex ring 23 and the plug-in sleeve 22, and the inner liner bottle 3 is not threadedly installed on the plug-in sleeve 22, that is, there is no internal thread at the mouth of the inner liner bottle 3; there is no external thread on the plug-in sleeve 22. A locking block 24 is provided on the inner wall of the convex ring 23, and a locking groove 34 is provided on the outer wall of the mouth of the inner liner bottle 3 for the locking block 24 to be inserted and the inner liner bottle 3 is limited to the pressing head 2 by rotation.

[0032] There are two locking blocks 24, and the two locking blocks 24 are evenly spaced and arranged circumferentially inside the convex ring 23. Since there are two locking blocks 24, there are also two locking grooves 34, and the two locking grooves 34 are evenly spaced and arranged circumferentially on the inner bottle 3, and the two locking grooves 34 correspond to the two locking holes one by one. The following takes the matching relationship between one locking block 24 and one locking groove 34 as an example for explanation.

[0033] Reference Figure 3 and Figure 5, the convex ring 23 is integrally formed with the pressing head 2, and the locking block 24 is integrally formed with the convex ring 23. The locking groove 34 includes a vertical groove 35 and a horizontal annular groove 36, and the vertical groove 35 and the horizontal annular groove 36 are connected to each other and form an L-shaped groove. The vertical groove 35 is opened at the top of the bottle mouth of the inner liner bottle 3, and the vertical groove 35 extends downward in the vertical direction, and the vertical groove 35 passes through the outer wall of the inner liner bottle 3. One end of the horizontal annular groove 36 is connected with the end of the vertical groove 35 away from the bottle mouth of the inner liner bottle 3, and the other end extends along the circumference of the inner liner bottle 3. When the inner liner bottle 3 is installed, the locking block will first be inserted into the vertical groove 35 and slide in the vertical groove 35 to the end of the vertical groove 35 close to the horizontal annular groove 36; then the inner liner bottle 3 is rotated so that the locking block 24 is completely transferred to the horizontal annular groove 36, so that the inner liner bottle 3 is installed on the pressing head 2 and is not easy to be directly pulled off from the pressing head 2.

[0034] Reference Figure 3 and Figure 5 The outer edge of the top of the locking block 24 near the transverse annular groove 36 is set to a chamfered angle, so that the locking block 24 can enter the transverse annular groove 36 more smoothly when the inner bottle 3 rotates. In addition, a locking inclined surface 37 that allows the locking block 24 to interfere with the transverse annular groove 36 is provided on the groove wall of the transverse annular groove 36 near the bottle mouth of the inner bottle 3. The locking inclined surface 37 gradually tilts toward the bottom of the inner bottle 3 along the direction in which the locking block 24 enters the transverse annular groove 36, so that the locking block 24 can interfere with the transverse annular groove 36.

[0035] The implementation principle of a push-type cosmetic bottle in the embodiment of the present application is: to install the inner bottle 3, it is only necessary to insert the locking block 24 into the vertical groove 35, and then rotate the inner bottle 3 to make the locking block 24 interfere with the rotation into the horizontal annular groove 36, thereby making the entire process of replacing the inner bottle 3 more convenient and quick.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
