[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0027] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or there may also be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used herein in the description of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0029] In this application, terms such as "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity or order of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0030] In this application, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a system, product or device including a series of units does not necessarily have to be limited to those units clearly listed, but may include other units not clearly listed or inherent to these products or devices.

[0031] See Figures 1 to 3 , an embodiment of the present application provides a cosmetic packaging bottle, including an integrally formed outer bottle 100 and an inner container 200, wherein the inner container 200 is used to contain cream-like cosmetics, and the outer bottle 100 includes a bottle mouth 110 and a bottle body 120.

[0032] Specifically, a part of the outer bottle 100 is reduced in diameter to form a bottle mouth 110. The bottle mouth 110 and the inner container 200 are of an integral structure, and there is a gap between the bottle body 120 and the inner container 200. This design not only reduces the overall material consumption, but also, when the packaging bottle is made of plastic, can avoid defects such as shrink marks that are likely to occur in the production of thick-walled plastic materials. In addition, the step of fixing the inner container 200 to the outer bottle 100 during assembly is omitted, making the assembly more convenient.

[0033] Furthermore, the bottle body 120 includes a barrel wall 130 and a bottom wall 140 that are separately arranged. In the prior art, generally, the bottom wall 140 is engaged with the inner side wall of the barrel wall 130. However, due to the characteristics of the material of the packaging bottle itself, the packaging bottle with this structure may have a situation where the bottle body 120 bulges outwards, resulting in a poor connection firmness between the bottom wall 140 and the barrel wall 130.

[0034] To solve this problem, in the cosmetic packaging bottle of this application, the bottom wall 140 has a first extension portion 141 that extends into the inner cavity of the barrel wall 130 and is arranged axially and a second extension portion 145 that extends radially. The first extension portion 141 is engaged with the inner side wall of the barrel wall 130, and the second extension portion 145 is engaged with the bottom end face of the barrel wall 130. That is, in the packaging bottle of this application, an axially limited engaging structure and a radially limited engaging structure are provided between the bottom wall 140 and the barrel wall 130. Compared with the prior art, the radially limited engaging structure can prevent the bottle body 120 from bulging outwards and improve the firmness between the barrel wall 130 and the bottom wall 140.

[0035] Specifically, referring to Figures 1 to 3 , one of the first extension portion 141 and the inner side wall is provided with an annular positioning groove 131, and the other is provided with a protrusion 142 that cooperates with the positioning groove 131. In this embodiment, the positioning groove 131 is provided on the inner side wall of the barrel wall 130, and the protrusion 142 is provided on the first extension portion 141.

[0036] Furthermore, considering the need for air exhaust when the barrel wall 130 and the bottom wall 140 are pressed and engaged and the stability after cooperation, the number of protrusions 142 is multiple, and an exhaust channel 143 is formed between adjacent two protrusions 142. Of course, the number of protrusions 142 can be selected according to requirements, and this application does not make special requirements. For example, in the figure, the number of protrusions 142 is specifically 2.

[0037] Referring to Figures 1 to 3 , the bottom end face of the barrel wall 130 is provided with an annular groove 132. Correspondingly, the second extension portion 145 has a convex ring 146 that extends into the annular groove 132. In the figure, the convex ring 146 is specifically provided at the edge portion of the second extension portion 145. Considering the overall aesthetics, the outer surface of the second extension portion 145 is flush with the bottom end face of the barrel wall 130.

[0038] To make the cosmetic packaging bottle more stable when placed, a recessed area 147 is formed by the middle part of the bottom wall 140 indenting inward (towards the inside of the barrel wall 130).

[0039] See Figure 1 and Figures 4 to 5 , the cosmetic packaging bottle of the present application further includes a cover body 300. The cover body 300 includes an outer cover 310 and an inner cover 320 which are fixedly connected. In the illustration, a first card slot 311 arranged axially and a second card slot 312 arranged circumferentially are provided on the inner peripheral wall of the outer cover 310, and a first positioning rib 327 and a second positioning rib 328 are provided on the outer peripheral wall of the inner cover 320. The first card slot 311 and the first positioning rib 327 cooperate to achieve circumferential limit, and the second card slot 312 and the second positioning rib 328 cooperate to achieve axial limit.

[0040] To facilitate the application of cosmetics, the packaging bottle of the present application further includes an application stick 313 for dipping cosmetics. As Figure 1 and 5 shown, to place the application stick 313, a sandwich layer 330 is formed between the outer cover 310 and the inner cover 320. The outer cover 310 is provided with an opening 314 for the application stick 313 to extend into the sandwich layer 330. Considering the problem of easy access, a part of the application stick 313 is exposed outside the outer cover 310, and the other part is located in the sandwich layer 330. When in use, the whole can be pulled out by operating the part exposed outside the outer cover 310.

[0041] In the prior art, a cover piece is generally provided above the inner container 200 to prevent cosmetics from being contaminated externally. However, when in use, it is necessary to first open the cover body 300 and then take out the cover piece to use, which is rather cumbersome. To solve this problem, the inner cover 320 of the present application includes a connecting portion 321 that is threadedly engaged with the bottle mouth 110 and a closing portion 325 for closing the bottle mouth 110. The closing portion 325 can directly close the inner container 200, omitting the operation of taking out the cover piece, which is more convenient to use.

[0042] Of course, to prevent cosmetics from accidentally overflowing from the inner container 200 and contaminating the packaging bottle, the closing portion 325 further has an inner plug 326 that extends into the inner container 200 and is in interference fit with the peripheral wall of the inner container 200.

[0043] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as these combinations of technical features do not conflict, they should all be considered as within the scope described in this specification. When the technical features in different embodiments are shown in the same drawing, it can be regarded that the drawing also discloses the combined examples of the respective embodiments involved.

[0044] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application.
