[0026] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] 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 an intermediate 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 an intermediate component.

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

[0029] 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 technical features indicated. 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, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0030] In this application, the terms "comprises" and "comprising" and any variations thereof are intended to cover non-exclusive inclusions, for example, a system, product or apparatus comprising a list of elements is not necessarily limited to those elements expressly listed but may include other elements not expressly listed or inherent to such products or apparatuses.

[0031] See also Figures 1 to 6 An embodiment of the present application provides a packaging bottle, comprising a bottle body 200 for containing cosmetics and a bottle cap 100, wherein the bottle cap 100 comprises an inner cap 120 and an outer cap 110 nested with each other, wherein the cosmetics refer to perfume, lotion, liquid foundation, etc. The outer cap 110 has a cavity for accommodating the inner cap 120, so that the inner cap 120 is completely hidden in the outer cap 110, and the two can be fixed by gluing, interference fit, etc., and this application does not make special requirements.

[0032] The inner cover 120 is formed of metal and includes a main body 130 and an elastic portion 140. Its sidewall has two axially extending and oppositely arranged cutouts 131, forming the elastic portion 140 between the two cutouts 131. The ends of the elastic portion 140 are connected to the main body 130. The elastic portion 140 bends toward the inside of the cavity and is provided with a latching protrusion 141 at the bend. The latching protrusion 141 is located in the middle of the elastic portion 140. In the figure, the latching protrusion 141 is elongated and extends circumferentially. To prevent deformation of the outer cover 110 due to stress, the wall thickness of the outer cover 110 is greater than that of the inner cover 120.

[0033] Of course, considering the stability of the bottle cap 100 and the bottle body 200 after being matched, the number of the elastic parts 140 is multiple. In this embodiment, the number of the elastic parts 140 is specifically 3, and they are evenly arranged along the circumference.

[0034] Preferably, the ratio of the length of the elastic part 140 to the length of the inner cover 120 is 1:2-3.5, the distance between the two cutouts 131 is 3mm-6mm, and the thickness of the elastic part 140 is 0.4mm-0.65mm. The elastic part 140 is thin as a whole and has good elasticity.

[0035] The inner cap 120 of the packaging bottle of the present application is made of metal. The two ends of the elastic part 140 are connected to the main body 130, and the elastic part 140 is bent toward the inner side of the cavity. The locking protrusion 141 is set on the elastic part 140. When combined with other components, the elastic part 140 has good anti-deformation ability, which can ensure that the separation force after multiple uses is still within the effective range, avoiding the problems of shaking and movement.

[0036] See also Figures 2 to 4 The bottle body 200 includes a bottle body 210 with a bottle mouth 211, a pump body 220 cooperating with the bottle body 210, and a shoulder sleeve 250 sleeved on the outer periphery of the pump body 220. The shoulder sleeve 250 is provided with an annular groove 251 cooperating with the clamping protrusion 141 to achieve axial limitation.

[0037] See also Figures 5 and 6 The pump body 220 includes a connecting portion 230 and a pressing cap 240 disposed on the connecting portion 230 (the pressing cap 240 is axially movable relative to the connecting portion 230). To connect with the bottle body 210, a snap-fit ​​structure is provided between the bottle body 210 and the connecting portion 230. In the figure, the snap-fit ​​structure includes an enlarged diameter section 212 disposed at the top of the bottle mouth 211 and a hook 231 disposed on the connecting portion 230.

[0038] In order to facilitate the engagement of the hook 231 with the enlarged diameter section 212, the connecting portion 230 is provided with a plurality of opening slots 232 extending to the bottom end surface, and a locking portion 233 is formed between the opening slots 232. The hook 231 is provided on the inner wall of the locking portion 233. Figure 6In this embodiment, there are eight open slots 232, evenly distributed along the circumference, forming eight corresponding engaging portions 233. Two hooks 231 are arranged on the inner wall of each engaging portion 233. When engaging with the expanded diameter section 212, the bottom of the hook 231 abuts against the top of the expanded diameter section 212. Then, under the action of force, the engaging portion 233 opens to allow the expanded diameter section 212 to extend until the expanded diameter section 212 is fully inserted. At this point, the hook 231 returns to engage with the bottom of the expanded diameter section 212.

[0039] In one embodiment, the bottle mouth 211 and the connecting portion 230 are hidden in the shoulder sleeve 250, and the pressing cap 240 is partially exposed to the shoulder sleeve 250 and movably cooperates with the shoulder sleeve 250 (the spring is omitted in the figure, and the movably cooperated means that under the action of downward pressure, the pressing cap 240 moves downward, and when the force on the pressing cap 240 is removed, the pressing cap 240 is reset under the action of the spring).

[0040] In one embodiment, in order to improve the sealing performance, a sealing ring 260 is installed between the connecting portion 230 and the enlarged diameter section 212 .

[0041] When the packaging bottle cap of the present application is closed, the latching protrusion 141 and the annular groove 251 are squeezed and rubbed, and the elastic part 140 is deformed outward until the latching protrusion 141 and the annular groove 251 are engaged, producing a clicking sound, indicating that the assembly is in place, and the elastic part 140 is reset at the same time.

[0042] The technical features of the above-described embodiments may be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as no contradiction exists between these combinations of technical features, they 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 deemed that the drawing also discloses examples of combinations of the various embodiments involved.

[0043] The above-described embodiments merely represent several implementation methods of the present application. 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 a person skilled in the art may make various modifications and improvements without departing from the spirit of the present application, and such modifications and improvements are all within the scope of protection of the present application.
