[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.
[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0028] In this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0029] In this application, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, for example, a system, product, or device that includes a series of units is not necessarily limited to those units that are explicitly listed, but may include other units that are not explicitly listed or that are inherent to such products or devices.
[0030] See Figures 1-5 One embodiment of this application provides a packaging bottle with a replaceable inner liner, including an outer bottle 100 and an inner liner 200 disposed inside the outer bottle 100. The inner liner 200 is used to hold creams or ointments. The outer bottle 100 includes a bottle body 120 and a bottle mouth 110. Of course, the packaging bottle of this application also includes a cap 300 that is threadedly engaged with the outer bottle 100. The cap 300 includes an inner cap 310 and an outer cap 320, which can be fixed together by glue, snaps, or other means. Since the cap 300 is not the focus of this application's improvement, it will not be described further below.
[0031] The outer bottle 100 and inner liner 200 in the existing packaging bottle are difficult to disassemble. After use, consumers cannot reuse the outer bottle 100 and can only discard the entire packaging bottle, which will cause a waste of resources.
[0032] To solve this problem, the bottom surface of the bottle body 120 of this application is provided with a through hole 142, the top of the bottle mouth 110 is narrowed to form a connecting part 111, the top of the inner liner 200 is provided with a folded edge 210, the connecting part 111 has an outer surface 112 and an inner surface 114, an axial limiting mechanism is provided between the outer surface 112 and the folded edge 210, and a circumferential limiting mechanism is provided between the inner surface 114 and the inner liner 200.
[0033] In one embodiment, the bottle opening 110 has an external thread 116, and the inner cap 310 has an internal thread that mates with the external thread 116, wherein the external thread 116 is located below the connecting portion 111.
[0034] When the cosmetics in the inner liner 200 are used up and need to be replaced, simply push the bottom of the inner liner 200 against the through hole 142 and push it upwards. After overcoming the resistance of the axial limiting mechanism, the inner liner 200 can be pushed out of the outer bottle 100. Compared with the existing technology, it is not only easier to disassemble, but also saves resources.
[0035] For details on the structure of folded edge 210, please refer to Figure 2 and Figure 5 The folded edge 210 includes a horizontally extending first folded edge 220 and a second folded edge 230 that is arranged vertically relative to the first folded edge 220 and extends downward (the second folded edge 230 is spaced a certain distance from the outer wall of the inner liner 200), and an axial limiting mechanism is disposed between the outer surface 112 and the second folded edge 230.
[0036] Furthermore, the axial limiting mechanism includes an annular groove 113 disposed on the outer surface 112 and an annular protrusion 231 disposed on the inner side of the second folded edge 230. Of course, the annular groove 113 can also be disposed on the inner side of the second folded edge 230 and the annular protrusion 231 can be disposed on the outer surface 112, as long as the two can achieve axial limiting, this application does not make any special requirements.
[0037] The top of the bottle mouth 110 is narrowed to form a step 117 at the connection position of the connecting part 111. Preferably, the end of the second folded edge 230 abuts against the step 117, and the outer peripheral wall of the second folded edge 230 is flush with the outer peripheral wall of the bottle mouth 110, making the shape more aesthetically pleasing.
[0038] Regarding the circumferential limiting mechanism, see [link / reference]. Figures 4-5The circumferential limiting mechanism includes a positioning groove 115 arranged axially on the inner surface 114 and a positioning rib 240 provided on the outer peripheral wall of the inner liner 200. In order to ensure the overall stability, there are multiple positioning grooves 115, which are arranged in a ring shape along the circumference. Correspondingly, there are also multiple positioning ribs 240, which are evenly arranged along the circumference.
[0039] Regarding the positioning rib 240, the bottom height of the positioning rib 240 is higher than the bottom height of the second fold 230, so that the second fold 230 covers the positioning rib 240, making the overall shape more aesthetically pleasing.
[0040] See Figure 2 and Figure 4 To reduce wall thickness and save materials, the bottle body 120 includes a separate cylindrical wall 130 and a bottom wall 140, with a through hole 142 located in the middle of the bottom wall 140.
[0041] In this embodiment, the bottom of the cylinder wall 130 is not circular, but roughly D-shaped. Therefore, regarding the connection between the cylinder wall 130 and the bottom wall 140, only the axial limiting of the two needs to be considered. Specifically, the bottom wall 140 has an extension 143 that extends into the inner cavity of the cylinder wall 130 and is arranged axially. The extension 143 engages with the inner sidewall of the cylinder wall 130. For example, as shown in the figure, the cylinder wall 130 has a locking protrusion 131, and the bottom wall 140 has a locking groove 144.
[0042] In one embodiment, the bottom wall 140 has a recessed area 141 in the middle, and a through hole 142 is located in the recessed area 141. The bottom of the inner liner 200 of this application protrudes downward, so the inner liner 200 is partially exposed from the through hole 142. This design is not only aesthetically pleasing, but also makes it easy to apply force to the bottom of the inner liner 200 to push the inner liner 200 out of the outer bottle 100.
[0043] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.
[0044] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
