Description

Technical Field

[0001] The present application relates to the field of cosmetic packaging, and in particular to a cosmetic packaging bottle. Background Art

[0002] Lip gloss is a cosmetic specially used for lips. It can make lips moist, plump and shiny after application, and is very popular among modern consumers. However, due to its own texture, existing lip gloss will produce stratification after long-term storage.

[0003] In order to solve the problem of stratification, a lip gloss packaging bottle capable of stirring is introduced on the market. For example, publication number CN220571714U discloses a lip gloss cosmetic with stirring function, which includes a bottle body, an upper cover, a central rod installed inside the upper cover, and a stirring sleeve that can rotate inside the bottle body, wherein the central rod can drive the stirring sleeve to rotate when rotating inside the bottle body. Therefore, when using cosmetics, one only needs to twist the upper cover to drive the central rod to rotate, and at the same time, the stirring sleeve can be driven to rotate left and right, thereby stirring the cosmetics evenly to restore the normal shape.

[0004] However, the volume of the stirring sleeve in the above-mentioned packaging bottle is relatively large, which occupies the cosmetic space in the bottle body. On the other hand, most of the existing lip gloss bottles are made of transparent materials, and the existence of the stirring sleeve makes the overall appearance less beautiful.

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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] See also Figure 1 to Figure 5 An embodiment of the present application provides a cosmetic packaging bottle, including a bottle body 200 with a bottle mouth 220 for containing cosmetics and a cover body 100 that cooperates with the bottle mouth 220 to close the bottle body 200. In the figure, the cover body 100 is threadedly connected with the bottle mouth 220, that is, an internal thread is provided in the cover body 100, and an external thread is provided on the outer periphery of the bottle mouth 220, and the internal thread and the external thread cooperate to achieve the fixation of the two.

[0044] The cover body 100 is connected with a brush rod 300 extending from the bottle mouth 220 into the bottle body 200 and a brush head 301 fixed at the end of the brush rod 300 for smearing. An inner plug 400 with a perforation 432 is provided at the bottle mouth 220, and the brush rod 300 passes through the perforation 432 and transitionally fits with it. In the figure, the brush head 301 is provided with a positioning column 302, and the brush rod 300 is provided with a positioning hole 303 that is engaged with the positioning column 302, and the two cooperate to achieve fixation. The transition fit between the brush rod 300 and the perforation 432 is used to scrape off the residual liquid, which can be either a clearance fit or an interference fit. The so-called clearance fit means that the gap is small enough to scrape off most of the liquid, and the two are more preferably interference fits.

[0045] In order to improve the problem of cosmetic stratification, the existing packaging bottle generally has a stirring sleeve inside the bottle body 200. On the one hand, the stirring sleeve is large in size and occupies a large space. On the other hand, the overall aesthetics is poor.

[0046] Therefore, in order to solve this problem, the brush rod 300 of the present application is rotationally connected to the cover body 100, and the brush rod 300 has a spiral section 311. When the spiral section 311 passes through the through hole 432, the inner plug 400 acts on the brush rod 300 to drive it to rotate.

[0047] When the brush rod 300 is inserted or pulled out, that is, when the spiral segment 311 passes through the through hole 432, the inner plug 400 will exert a tangential force on the spiral segment 311, thereby causing the brush rod 300 to rotate, and the brush rod 300 will drive the brush head 301 to rotate in the bottle body 200, thereby stirring the cosmetics in the bottle body 200 and improving the problem of cosmetic stratification.

[0048] See also Figure 1 to Figure 3 The brush rod 300 includes a rod body 310 and a joint 320 plugged with the cover body 100, and the spiral section 311 is a part of the rod body 310. Considering the problem of structural strength, the rod body 310 and the joint 320 in the figure are integrally formed. In order to facilitate the connection with the cover body 100, one of the cover body 100 and the joint 320 is provided with an annular groove 321, and the other is provided with a protrusion 110 engaged with the annular groove 321, and the two cooperate to achieve axial fixation.

[0049] In this embodiment, the annular groove 321 is disposed on the outer wall of the joint 320 , and the protrusion 110 is an annular structure, disposed on the inner wall of the cover body 100 and located above the internal thread.

[0050] To facilitate fixation, the joint 320 has a conical guide portion 322 that guides the protrusion 110 and is inserted into the annular groove 321. During the specific assembly, since the protrusion 110 is located above the internal thread, the position is relatively deep, and a large force is required to force the guide portion 322 to pass over the protrusion 110. The overall assembly is more troublesome, and the forced passing process may cause deformation of the components, affecting the smoothness of the subsequent rotation of the brush rod 300.

[0051] In order to solve this problem, the joint 320 of the present application is a hollow structure, and the side wall has a longitudinally extending cutout 323, and the cutout 323 extends to the bottom of the annular groove 321. In the present embodiment, the number of the cutouts 323 is 2, which are symmetrically distributed. The two cutouts 323 divide the guide portion 322 into two symmetrical parts. In the process of the guide portion 322 passing over the protrusion 110, the protrusion 110 and the outer peripheral wall of the guide portion 322 are squeezed. At this time, the two parts are adaptively deformed inward, and the guide portion 322 can easily pass over the protrusion 110 (the cutout 323 is reset after the guide portion 322 passes over the protrusion 110), so that the annular groove 321 and the protrusion 110 can cooperate with each other smoothly.

[0052] See also Figure 2 The joint 320 is in contact and sealed with the inner plug 400, so that the cosmetics have a better sealing effect and prevent the cosmetics from being contaminated and deteriorated by the outside world.

[0053] In this embodiment, the brush head 301 is a flat brush. The flat brush can generate a greater stirring force when rotating, and can better stir the cosmetics to solve the problem of stratification.

[0054] See also Figure 4-5 The inner plug 400 is fixedly connected to the bottle mouth 220, and has an axial limiting mechanism and a circumferential limiting mechanism. Specifically, the axial limiting mechanism includes a convex ring 440 provided on the outer peripheral wall of the inner plug 400 and a groove 221 provided on the inner wall of the bottle mouth 220 and matched with the convex ring 440; the circumferential limiting mechanism includes a positioning rib 450 axially arranged on the outer peripheral wall of the inner plug 400 and a positioning groove 222 provided on the inner wall of the bottle mouth 220 and matched with the positioning rib 450. In order to make the force more uniform, the number of the positioning ribs 450 can be set according to the needs, and this application does not make special requirements. In this embodiment, the number of the positioning ribs 450 is 4, and they are evenly arranged along the circumference.

[0055] The inner plug 400 has a radially enlarged overlap portion 410, a middle connection portion 420, and an inverted tapered scraper portion 430, and a platform 431 with a perforation 432 is provided at the bottom end of the scraper portion 430. After the inner plug 400 is fixed to the bottle mouth 220, the overlap portion 410 is exposed to the outside of the bottle mouth 220 and abuts against the top surface of the bottle mouth 220, wherein the outer surface of the overlap portion 410 is flush with the outer surface of the bottle mouth 220, making the overall appearance more beautiful.

[0056] In this embodiment, the perforation 432 is non-circular, preferably, see Figure 3 and Figure 5The rod body 310 also includes a straight section 312 extending straightly to connect the spiral section 311 (the straight section 312 is located at both ends of the rod body 310, and the spiral section 311 is located in the middle of the rod body 310). The cross-sectional shapes of the straight section 312 and the spiral section 311 are consistent and can both be adapted to the perforation 432. The perforation 432 is in the shape of a rounded rectangle, which can limit the circumferential rotation of the straight section 312 and can also scrape off excess cosmetics adhering to the surface of the brush rod 300 and the brush head 301 to reduce the waste of cosmetics.

[0057] The pitch of the spiral section 311 is preferably 12.0 mm to 19.5 mm.

[0058] In another embodiment, see Figure 6-7 The cross-sectional shape of the straight section 312 and the spiral section 311 is a regular hexagon, and correspondingly, the shape of the through hole 432 is also a regular hexagon. Of course, the rod body 310 can also be set to a non-circular structure, which can be selected according to needs, and this application will not be further elaborated.

[0059] In one embodiment, the bottle body 200 includes a bottle body 210 with a uniform diameter, and the bottle mouth 220 has a shoulder 223 connected to the bottle body 210. In order to facilitate installation, the top of the bottle body 210 has a radially reduced diameter portion 211, and the inner circumferential wall of the shoulder 223 is provided with an annular groove 224 for the diameter reduction portion 211 to extend into and cooperate with. The diameter reduction portion 211 and the annular groove 224 can be fixed by glue or a snap-fit ​​structure, and this application does not make specific requirements. The outer surfaces of the bottle body 210 and the shoulder 223 are flush, and the overall shape is more beautiful.

[0060] 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.

[0061] 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.
