[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification 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.

[0027] In this application, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating 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 the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0028] In this application, the terms "comprises" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a system, product or device comprising a series of units is not necessarily limited to those units explicitly listed, but may include other units not explicitly listed or inherent to these products or devices.

[0029] See also Figure 1 to Figure 4 An embodiment of the present application provides a convenient packaging bottle, including a cover body 100 and a bottle body 200, wherein the bottle body 200 includes a bottle body 210 and a bottle mouth 220, and the interior of the bottle body 210 is used to contain cream-type cosmetics.

[0030] In order to protect the cosmetics (to prevent the cosmetics from being oxidized due to excessive contact with the air), the top of the bottle body 200 of the existing packaging bottle is also provided with an inner cover 120, wherein the cover body and the inner cover 120 are two independent parts. When the cosmetics need to be used, the cover body and the inner cover 120 need to be removed separately before use, which is a rather troublesome overall operation.

[0031] In order to solve this problem, in the packaging bottle of the present application, the cover body 100 includes an outer cover 110 threadedly connected to the bottle mouth 220 and an inner cover 120 extending into the bottle mouth 220 and having an interference fit with the bottle mouth 220 (the interference fit can not only prevent the cosmetics from excessive contact with the air and oxidation, but also prevent the cosmetics from leaking into the outer cover 110 through the inner cover 120 when the bottle body 200 is tilted or inverted), and the edge of the inner cover 120 is engaged with the outer cover 110.

[0032] The present application sets the inner cover 120 and the outer cover 110 as a snap-fit ​​structure. When in use, the outer cover 110 can be removed to simultaneously separate the inner cover 120 from the bottle body 200. After use, only the outer cover 110 needs to be screwed on. At this time, the inner cover 120 can be interference fit with the bottle mouth 220. Compared with the existing technology that requires additional manual removal / putting on of the inner cover 120, the operation is more convenient.

[0033] join Figures 1 to 3 The inner cover 120 includes a lap joint 130 superimposed on the top surface of the bottle mouth 220, and a tightening portion 140 extending into the bottle mouth 220 and interfering with its inner circumference. When the outer cover 110 and the bottle body 200 are tightened, the lap joint 130 is clamped between the top wall of the inner cover 120 and the top of the bottle mouth 220. In order to make it more beautiful, the lap joint 130 is flush with the outer circumference of the bottle mouth 220.

[0034] In this embodiment, the tensioning part 140 is a hollow structure, which reduces the use of materials and saves energy and is environmentally friendly. Of course, in order to increase the structural strength of the inner cover 120, the middle position of the tensioning part 140 also has a protrusion 150. In this embodiment, the height of the protrusion 150 is lower than the overlapping part 130.

[0035] In order to enable the inner cover 120 and the outer cover 110 to engage smoothly, the overlap portion 130 is provided with a radially extending positioning block 131, and the outer cover 110 has a positioning groove 111 that cooperates with the positioning block 131 to limit the axial movement of the two. Considering the overall stability, the number of positioning blocks 131 and corresponding positioning grooves 111 is multiple, and the specific number can be set according to needs. In this embodiment, the number of positioning blocks 131 in the figure is 3, and they are evenly distributed along the circumference. Preferably, the positioning block 131 and the overlap portion 130 are integrally formed to increase the structural strength.

[0036] See also Figure 4 The inner wall of the outer cover 110 is provided with circumferentially arranged limiting protrusions 112, and a positioning groove 111 is formed between the limiting protrusions 112 and the top wall of the inner cover 120. In order to facilitate the positioning block 131 to pass over the limiting protrusions 112 and enter the positioning groove 111, the bottom of the limiting protrusion 112 has a transition slope.

[0037] Furthermore, in this embodiment, a circumferential limiting structure is also provided between the inner cover 120 and the outer cover 110. Specifically, the circumferential limiting structure includes a notch 132 provided on the positioning block 131, and a positioning rib 113 provided on the outer cover 110 and arranged along the axial direction and cooperating with the notch 132. Preferably, the notch 132 is located in the middle of the positioning block 131, and the positioning rib 113 extends downward from the top wall of the inner cover 120 and crosses the limiting protrusion 112.

[0038] Furthermore, considering the aesthetics of the overlapped portion 130 and the inner cover 120 after they are matched, a circumferentially arranged decorative rib 116 is provided at the top wall of the outer cover 110 to fill the gap between the overlapped portion 130 and the inner circumferential wall of the outer cover 110, wherein the decorative rib 116 is arranged to avoid the positioning block 131. Preferably, the thickness of the decorative rib 116 is the same as that of the overlapped portion 130.

[0039] See also Figures 1 to 4 The bottle mouth 220 is provided with an external thread 221, the outer cover 110 is provided with an internal thread 114 matched with the external thread 221, and an escape zone 115 is provided at the internal thread 114 to allow the positioning block 131 to pass through. In this embodiment, the escape zone 115 is arranged opposite to the limiting protrusion 112, so that the positioning block 131 can quickly pass over the limiting protrusion 112 to enter the positioning groove 111 after passing through the escape zone 115.

[0040] See also Figure 1-2 The bottle mouth 220 shrinks relative to the outer wall of the bottle body 210. When the bottle mouth 220 and the cover body 100 are tightened, the outer surfaces of the cover body 100 and the bottle body 210 are flush, so that the overall shape is more beautiful.

[0041] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0042] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
