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.

[0028] 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.

[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 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.

[0030] 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.

[0031] See also Figure 1 to Figure 6 An embodiment of the present application provides an anti-eccentric packaging bottle, comprising a bottle body 100, a shoulder sleeve 200 and a pump body 300, wherein the shoulder sleeve 200 is provided with a central hole 210 for installing the pump body 300, the bottle body 100 comprises a bottle body 110, a bottle mouth 120 radially reduced relative to the bottle body 110, and a bottle shoulder 130 extending laterally between the bottle body 110 and the bottle mouth 120, the pump body 300 can pump out the cosmetics located in the bottle body 100, wherein the pump body 300 can adopt an existing structure, which is not elaborated in detail in this embodiment.

[0032] Although the existing shoulder cover 200 and the bottle body 100 can cooperate with each other, due to improper operation during assembly, an eccentricity problem may occur between the assembled shoulder cover 200 and the bottle body 100.

[0033] In order to solve this problem, the shoulder sleeve 200 provided in the present application comprises a connecting portion 220 connected to the central hole 210 and threadedly connected to the bottle mouth 120, a decorative portion 240 connected to the bottle body 110, and a positioning portion 230 located between the connecting portion 220 and the decorative portion 240 and cooperating with the bottle shoulder 130. Figure 2 and Figure 5 ), the connection part 220, the positioning part 230 and the decorative part 240 are arranged in sequence from the inside to the outside, the inner wall of the connection part 220 is provided with an internal thread, and the outer wall of the bottle mouth 120 is provided with an external thread, and the internal thread and the external thread cooperate to realize the fixed connection between the shoulder cover 200 and the bottle body 100. Furthermore, since the internal thread is provided on the innermost connection part 220, it can also avoid the appearance of the shrinkage mark.

[0034] The packaging bottle of the present application is provided with a connecting portion 220, a decorative portion 240 and a positioning portion 230, wherein the connecting portion 220 is connected to the bottle mouth 120, and the positioning portion 230 can cooperate with the bottle shoulder 130 for positioning, and compared with the prior art, it can prevent the shoulder sleeve 200 from being eccentric.

[0035] In this embodiment, the connecting portion 220, the decorative portion 240 and the positioning portion 230 are all annular structures arranged around the central hole 210. In order to enhance the structural strength, a reinforcing rib 221 is provided between the connecting portion 220 and the positioning portion 230 to connect the two. In this embodiment, the reinforcing rib 221 is a strip structure, the number of which is specifically 6, and is evenly arranged along the circumference. Of course, the specific number can be selected according to demand, and this application does not make any special requirements. In order to further improve the structural strength of the decorative portion 240, the thickness of the decorative portion is greater than the thickness of the connecting portion 220 / positioning portion 230. Preferably, the thickness ratio is 1.5 to 3:1.

[0036] See also Figure 1-2 The heights of the decorative portion 240 , the positioning portion 230 and the connecting portion 220 decrease in sequence, and the connecting portion 220 and the positioning portion 230 are hidden inside the decorative portion 240 , making the overall appearance more beautiful.

[0037] In one embodiment, the bottle shoulder 130 has an annular boss 131, and the positioning portion 230 abuts against the outer peripheral wall of the boss 131, which can limit the deflection of the shoulder sleeve 200 and have an anti-eccentric effect. Among them, the connecting portion 220 is located above the boss 131 and close to the boss 131.

[0038] For further information, see Figure 5The distance between the connecting portion 220 and the positioning portion 230 is M1, and the distance between the positioning portion 230 and the decorative portion 240 is M2, wherein preferably, M1:M2=1:2~4.

[0039] See also Figure 1 to Figure 6 In order to prevent the pump body 300 from being separated from the shoulder sleeve 200, the center hole 210 has a radially reduced limiting portion 211, and the pump body 300 has a radially enlarged anti-detachment portion 310 higher than the limiting portion 211. In this embodiment, the anti-detachment portion 310 is specifically an annular protrusion. The pump body 300 also has a convex ring 320, which is clamped between the limiting portion 211 and the bottle mouth 120, wherein the anti-detachment portion 310 is located above the convex ring 320. When the pump body 300 and the shoulder sleeve 200 are assembled, the limiting portion 211 is engaged between the anti-detachment portion 310 and the convex ring 320 to achieve axial limitation.

[0040] In order to seal the bottle mouth 120 and improve the sealing performance, a sealing ring 400 is arranged between the convex ring 320 and the bottle mouth 120 , wherein the cross section of the sealing ring 400 is consistent with the cross section of the convex ring 320 .

[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.
