[0053] 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.

[0054] like Figure 1 , Figure 2 As shown, the cosmetic double-material mother-and-child tube provided in this embodiment includes: an upper cover component 100, a lower cover component 200, an outer tube component 300 and an inner tube component 400.

[0055] The upper cover member 100 is rotatably connected to the lower cover member 200 . Specifically, the upper cover member 100 is hingedly mounted on the lower cover member 200 , so that the upper cover member 100 can rotate relative to the lower cover member 200 .

[0056] The lower cover member 200 is provided with a total discharge hole 210. It should be noted that the total discharge hole 210 is located at an eccentric position of the top end surface of the lower cover member 200 to ensure that the total discharge hole 210 can move to switch the material body for use.

[0057] The inner tube bottle mouth of the inner tube member 400 is clamped with the outer tube member 300. Specifically, in an optional embodiment, the outer wall of the inner tube bottle mouth of the inner tube member 400 is provided with an inner tube clamping protrusion 410, and the inner wall of the outer tube bottle mouth of the outer tube member 300 is provided with an outer tube inner clamping groove 330. The inner tube clamping protrusion 410 extends into the outer tube inner clamping groove 330 to clamp the inner tube member 400 to the outer tube member 300, effectively preventing the inner tube member 400 and the outer tube member 300 from separating and falling out.

[0058] The outer tube bottle mouth end of the outer tube member 300 is provided with a first discharge hole 310 and a second discharge hole 320, and the internal cavity of the inner tube member 400 forms a first storage cavity 10. The outer diameter of the inner tube member 400 is smaller than the inner diameter of the outer tube member 300, so that the inner tube member 400 can be placed in the outer tube member 300, and the second storage cavity 20 is formed between the outer wall of the inner tube member 400 and the inner wall of the outer tube member 300. The first storage cavity 10 is connected with the total discharge hole 210 through the first discharge hole 310, or the second storage cavity 20 is connected with the total discharge hole 210 through the second discharge hole 320. When the cosmetic material in the first storage cavity 10 needs to be used, the first discharge hole 310 is connected with the total discharge hole 210, and when the cosmetic material in the second storage cavity 20 needs to be used, the second discharge hole 320 is connected with the total discharge hole 210.

[0059] The outer tube bottle mouth of the outer tube member 300 is snap-fitted with the lower cover member 200, and the outer tube member 300 is configured to be able to rotate relative to the lower cover member 200 to control the total discharge hole 210 to be connected with the first discharge hole 310 or the second discharge hole 320. Specifically, in an optional embodiment, an annular connecting tube 220 is formed in the lower cover member 200 extending toward the outer tube member 300, and the connecting tube 220 can be covered on the outer tube bottle mouth. The inner wall of the connecting tube 220 is provided with a lower cover snap-fitting protrusion 221, such as Figure 7 As shown, the outer wall of the outer tube bottle mouth of the outer tube component 300 is provided with an outer tube outer clamping groove 340, and the lower cover clamping protrusion 221 extends into the outer tube outer clamping groove 340, so that the outer tube component 300 will not fall off from the lower cover component 200, and the outer tube component 300 can rotate relative to the lower cover component 200.

[0060] like Figure 3 , Figure 4 As shown, the upper cover member 100 is provided with a pushing protrusion 110. Specifically, the end surface protrusion of the upper cover member 100 close to the lower cover member 200 is formed with a pushing protrusion 110. When the upper cover member 100 is covered on the lower cover member 200, the pushing protrusion 110 extends into the total discharge hole 210 to push the residual material in the total discharge hole 210 into the first storage cavity 10 or the second storage cavity 20.

[0061] It should be noted that in order to ensure that the residual material does not contaminate the storage chamber, when the residual material is the material body in the first storage chamber 10, the first discharge hole 310 is connected with the total discharge hole 210, and when the upper cover member 100 is covered on the lower cover member 200, the pushing protrusion 110 extends into the total discharge hole 210 to push the residual material into the first storage chamber 10; when the residual material is the material body in the second storage chamber 20, the second discharge hole 320 is connected with the total discharge hole 210, and when the upper cover member 100 is covered on the lower cover member 200, the pushing protrusion 110 extends into the total discharge hole 210 to push the residual material into the second storage chamber 20.

[0062] like Figure 6 As shown, in an optional embodiment, the outer tube bottle mouth of the outer tube member 300 is provided with a snap-fit ​​seat 350, and the snap-fit ​​seat 350 is arranged at the corner of the outer tube bottle mouth of the outer tube member 300 and the outer tube bottle body of the outer tube member 300; the end surface of the connecting tube 220 close to the outer tube member 300 extends downward to form a blocking portion 222, and the side of the blocking portion 222 can abut against the snap-fit ​​seat 350 to limit the rotation range of the outer tube member 300 relative to the lower cover member 200.

[0063] It should be noted that part of the end surface of the connecting tube 220 is provided with a blocking portion 222, while the other part of the end surface is not provided with the blocking portion 222. The clamping seat 350 moves in the area where the blocking portion 222 is not provided, ensuring that the outer tube component 300 can make a 180° rotational movement relative to the lower cover component 200 to switch the material body.

[0064] like Figure 5 As shown, in an optional embodiment, a contact protrusion 223 is provided on the end face of the connecting tube 220 close to the outer tube member 300; an abutment protrusion 351 is provided on the top of the clamping seat 350, and the abutment protrusion 351 and the contact protrusion 223 both have a certain elasticity, and the contact protrusion 223 can contact with the abutment protrusion 351, and during the rotation process, the contact protrusion 223 can continue to move over the abutment protrusion 351, and when the contact protrusion 223 can contact with the abutment protrusion 351, a sound can be made to remind the user that the material body switching rotation movement is in progress.

[0065] like Figure 8 As shown, in an optional embodiment, the inner tube bottle mouth of the inner tube member 400 extends toward the outer tube bottle mouth to form an inner tube discharge pipe 420 , and the inner tube discharge pipe 420 extends into the first discharge hole 310 .

[0066] Specifically, a protective tube is provided in the first discharge hole 310 , and the inner tube discharge pipe 420 extends into the protective tube. The material in the first storage cavity 10 flows out through the inner tube discharge pipe 420 , and then can flow from the first discharge hole 310 into the main discharge hole 210 .

[0067] In an optional embodiment, the outer side of the inner tube bottle mouth of the inner tube member 400 is recessed inward to form a discharge channel 430, and two discharge channels 430 are provided. The two discharge channels 430 are symmetrically arranged on the inner tube bottle mouth, and the discharge channels 430 are respectively connected to the second discharge hole 320 and the second storage chamber 20.

[0068] Specifically, the disposition of the discharge channel 430 can ensure that there is a channel between the inner wall of the inner tube member 400 and the inner wall of the outer tube member 300 , and the material in the second material storage chamber 20 flows along the discharge channel 430 and flows out from the second discharge hole 320 .

[0069] The cosmetic double-material mother-and-child tube provided in the present embodiment is provided with a pushing protrusion 110 on the upper cover member 100. When the upper cover member 100 is covered on the lower cover member 200, the pushing protrusion 110 extends into the total discharge hole 210 of the lower cover member 200, so that the residual material body in the total discharge hole 210 can be pushed into the first storage cavity 10 or the second storage cavity 20, so as to avoid residual material remaining in the total discharge hole 210. In addition, the whole is easy to use, and it is only necessary to drive the outer tube member 300 to rotate relative to the lower cover member 200 to control the total discharge hole 210 to be connected with the first discharge hole 310 or the second discharge hole 320, so as to switch the material body for use.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this 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. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
