Description

Technical Field

[0001] This application relates to the field of cosmetic packaging, and in particular to a cosmetic packaging bottle. Background Technology

[0002] The packaging bottles for liquid cosmetics such as lip gloss and lip balm typically consist of a bottle body, a brush handle, and a cap. Existing caps are mostly made of plastic and generally employ a multi-layered structure (e.g., including an outer cap and an inner cap). Because the plastic materials of each layer in this multi-layered structure may differ, these multi-layered composite plastic structures are often difficult to disassemble, hindering recycling and failing to meet environmental protection requirements. Therefore, further improvements are necessary. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a cosmetic packaging bottle.

[0004] A cosmetic packaging bottle includes a bottle body, a brush handle, and a cap. The bottle body has a receiving space, and the cap connects to the bottle body to close the receiving space. The cap includes an outer cap and an inner cap, both made of metal and nested within each other. The outer cap is formed by deformation of a first metal sheet, and the inner cap is formed by deformation of a second metal sheet. The inner cap has a positioning groove. The brush handle is made of metal and includes a distal end and a proximal end. The proximal end extends into the positioning groove and is fixedly connected to the inner cap by mechanical deformation. The distal end extends into the receiving space of the bottle body.

[0017] 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.

[0018] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component. When a component is said to be "set on" another component, it can be directly set on the other component or there may be an intervening component.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] join Figures 1-4 One embodiment of this application provides a cosmetic packaging bottle, including a bottle body 100, a brush handle 200, and a cap 300. The bottle body 100 has a receiving space for holding liquid cosmetics such as lip gloss or lip balm, and the cap 300 is connected to the bottle body 100 to seal the receiving space.

[0023] The existing cover 300 is generally a multi-layer composite plastic structure, which is difficult to disassemble after use, hindering recycling and is not environmentally friendly. In order to solve this problem, the cover 300 of this application includes an outer cover 310 and an inner cover 320 that are nested together and are both made of metal. The outer cover 310 is formed by deformation of a first metal sheet, and the inner cover 320 is formed by deformation of a second metal sheet.

[0024] Considering the installation of the brush handle 200, a positioning groove 331 is provided on the inner cover 320. To further facilitate recycling, preferably, the brush handle 200 is made of metal and includes a distal end 220 and a proximal end 210. The proximal end 210 extends into the positioning groove 331 and is fixedly connected to the inner cover 320 by mechanical deformation to ensure that it will not loosen during use. The distal end 220 extends into the accommodating space of the bottle body 100.

[0025] In one embodiment, the mechanical deformation method is not a single option and can be flexibly selected according to the actual production process, product strength requirements, etc., specifically including one or more of rolling, extrusion, and dotting. See also Figure 1 and Figure 4 The part where the brush rod 200 and the inner cover 320 undergo mechanical deformation is flattened. The flattening structure can not only ensure the anti-rotation effect of the two in the circumferential direction, but also improve the axial separation force, further enhancing the connection stability.

[0026] For details regarding the fit between the positioning slot 331 and the brush rod 200, please refer to [link / reference needed]. Figures 1-2 The brush rod 200 includes, from top to bottom, a connecting part 230, a sealing part 240, and an extension part 250. The connecting part 230 is adapted to the shape of the positioning groove 331 (for example, the connecting part 230 is a cylindrical structure), extends into the positioning groove 331, and is fixedly connected to it. The top of the positioning groove 331 is also provided with a vent hole 332 to prevent the connecting part 230 from rebounding when it is inserted into the positioning groove 331.

[0027] In the figure, a brush head 251 is fixed to the end of the extension 250. The brush head 251 can be a flocked brush head, a metal brush head, etc. It is preferred to use a metal brush head to further increase the metal ratio of the packaging bottle, so that the cap 300 and the brush handle 200 are both made of metal, which is convenient for recycling.

[0028] The brush handle 200 and the brush head 251 can be fixed together by adhesive. When the brush head 251 is made of metal, the brush handle 200 and the brush head 251 can also be integrally formed.

[0029] The packaging bottle of this application, including the outer cap 310, inner cap 320, and brush handle 200, is made of metal. After use, all of the above components can be recycled, which is more environmentally friendly than existing technologies.

[0030] See Figures 3-4 The inner cover 320 includes, from top to bottom, a connecting portion 330, a connecting portion 340 in the middle, and a positioning portion 350, with the radial dimensions of the connecting portion 330, the connecting portion 340, and the positioning portion 350 increasing sequentially. In one embodiment, the connecting portion 330 forms the aforementioned positioning groove 331.

[0031] In one embodiment, see Figures 1-3The connecting part 340 is threadedly connected to the bottle body 100. The bottle body 100 is provided with an external thread 110, and the connecting part 340 is provided with an internal thread 341. Due to the limitations of the thread structure, the diameter of the connecting part 340 cannot be made too large. Therefore, in this application, the positioning part 350 of the inner cover 320 is fixedly connected to the outer cover 310.

[0032] Because the gap between the connecting part 340 and the outer cover 310 is large, the connecting part 340 and the connecting part 330 will shake when only the positioning part 350 is fixedly connected to the outer cover 310. Therefore, the packaging bottle of this application also includes a connector 360 disposed between the outer cover 310 and the inner cover 320. The connector 360 is made of metal and is formed by the deformation structure of a third metal sheet.

[0033] In one embodiment, the connector 360 is a cylindrical structure open at both ends, including an upper section 361 and a lower section 362 with a reduced diameter relative to the upper section 361. The upper section 361 is fixedly connected to the outer cover 310, and the lower section 362 is fixedly connected to the connecting portion 340, maintaining the circumferential stability of the inner cover 320 to prevent shaking. The fixed connection described above can be secured using adhesive.

[0034] In one embodiment, a step 351 is formed at the junction of the connecting part 340 and the positioning part 350. Preferably, in the assembled cover 300, the lower section 362 abuts against the step 351. This structure can indicate that the inner cover 320 is assembled in place.

[0035] In one embodiment, the bottom of the outer cover 310 is provided with an inward flange 311 to prevent cuts. Furthermore, the top of the upper section 361 is also provided with an inward flange 363. See Figures 1-2 The packaging bottle includes an inner plug 120 located at the opening of the bottle body 100 (i.e., the bottle mouth), and the inner plug 120 has a perforation through which the brush rod 200 (specifically the extension 250 and the brush head 251) passes.

[0036] The inner plug 120 includes an outwardly folded overlapping portion 130, a middle transition portion 140, and a reduced-diameter scraping portion 150. After the inner plug 120 is fixed to the bottle body 100, the overlapping portion 130 is exposed outside the bottle mouth and abuts against the top surface of the bottle mouth. The outer surface of the overlapping portion 130 is flush with the outer surface of the bottle mouth, making the overall appearance more aesthetically pleasing and ensuring that there are no sharp edges at the mouth, thus eliminating the safety hazard of cutting hands.

[0037] See Figures 1-2 The outer surface of the sealing part 240 is inverted conical. When the packaging bottle is closed, the sealing part 240 can be press-fitted with the transition part 140 of the inner plug 120 to achieve the sealing function.

[0038] 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.

[0039] 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.
