Heat-resistant multifunctional bottle cap

Abstract

The present invention discloses a multifunctional, heat-resistant bottle cap, comprising an assembly and a lower sleeve. The lower sleeve is disposed outside the assembly and further comprises a metal insert disposed between the inner and outer walls of the assembly. The inner wall of the lower end of the lower sleeve is provided with at least one deformation groove, which is used to deform the edge of the lower sleeve at the deformation groove when the bottle cap is pulled. The provision of the metal insert improves the assembly's bottle-hanging strength, providing the assembly with heat-resistant functionality. The provision of the deformation groove also reduces the strength of the lower sleeve. Whenever the bottle cap is pulled, the lower sleeve deforms at the deformation groove, thereby damaging its appearance and achieving a straightforward anti-counterfeiting function.

Description

Technical Field

[0001] The present invention relates to the technical field of bottle cap anti-counterfeiting, and in particular to a multifunctional bottle cap that is heat-resistant and can be pulled out. Background Art

[0002] Bottle caps are a crucial component of beverage packaging and the first point of contact for consumers. They maintain a tight seal around the contents, while also providing tamper-evident protection and safety. Consequently, they are widely used in bottled products. As an upstream industry for the food, beverage, alcohol, chemical, and pharmaceutical industries, they are a key component of bottle container packaging.

[0003] Anti-counterfeiting has long been a problem that wine producers must face. In order to improve the anti-counterfeiting and sealing performance of bottle caps, most existing wine bottle caps use a combined bottle cap structure. For example, the patent number CN215286199U discloses a universal anti-counterfeiting bottle cap for sauce-flavored wine, including an inner plug, an assembly component, an inner cover, a middle ring, an upper cover, and a lower cover; although such a bottle cap improves the anti-counterfeiting and sealing performance of the bottle cap, it has the following shortcomings: the bottle cap is made of plastic injection molding, and due to the characteristics of plastic, when it is in a high-temperature environment, unscrupulous vendors can use equipment to evenly pull the bottle cap out of the bottle mouth (specifically, the teeth of the assembly component are separated from the glass bottle mouth, making the connection between the bottle cap and the glass bottle invalid), and then replace the wine to counterfeit it and then install the bottle cap.

[0004] Prior art solutions address this issue by using a metal sleeve to hang the bottle. For example, a separate anti-counterfeiting, anti-detachment bottle cap (publication number CN218199803U) includes a separate assembly component body and a metal inner sleeve. While this bottle cap solves the aforementioned hot-detachment issue, it does not indicate that the cap has been pulled, even if it is forcibly pulled, as long as the cap is not damaged, and thus lacks a warning function. Summary of the Invention

[0005] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a multifunctional bottle cap that is resistant to heat pulling. The strength of the component for hanging the bottle is improved by setting a metal insert, so that the component has an anti-heat pulling function. At the same time, the strength of the lower sleeve is reduced by setting a deformation groove. As long as the bottle cap is subjected to pulling, the lower sleeve will be deformed at the deformation groove, thereby destroying the appearance of the lower sleeve and realizing an intuitive anti-counterfeiting function.

[0006] The object of the present invention is achieved through the following technical solutions:

[0007] A multifunctional bottle cap that is heat-resistant and can be pulled out of a container includes a component and a lower sleeve. The lower sleeve is arranged outside the component and further includes a metal insert. The metal insert is arranged between the inner wall and the outer wall of the component. The inner wall of the lower end of the lower sleeve is provided with at least one deformation groove. The deformation groove is used to deform the edge of the lower sleeve at the deformation groove when the bottle cap is pulled out.

[0008] Furthermore, the metal insert includes a metal sleeve, the metal sleeve is evenly provided with a plurality of notches along the circumference, and the bottom edges of the notches are provided with metal clips with upper ends inclined toward the center of the metal sleeve.

[0009] Furthermore, the top edge of the metal sleeve is folded inward to form a pressing platform to press on the component, and the bottom edge of the metal sleeve is folded outward to form a tensioning portion.

[0010] Furthermore, the portion of the metal sleeve below the metal clip is arranged between the inner wall and the outer wall of the component, and the portion of the metal sleeve above the metal clip is exposed to the component.

[0011] Furthermore, the metal insert is integrally formed with the component by in-mold injection molding.

[0012] Furthermore, it also includes an outer cover and an inner cover, wherein the outer cover is arranged outside the inner cover, and the inner cover is connected to the assembly;

[0013] The inner cover includes a hard connecting portion and a soft sealing portion. The connecting portion is threadedly connected to the component, and the sealing portion is sealed at the wine outlet of the component.

[0014] Furthermore, the inner cover and the outer cover are fastened together by means of a stepped buckle.

[0015] Furthermore, the stepped hanging buckle includes a first boss arranged on the inner wall of the outer cover and a second boss arranged on the outer wall of the inner cover, and two opposite surfaces of the first boss and the second boss are inclined structures.

[0016] Furthermore, a positioning groove is provided on the inner wall of the lower end of the component.

[0017] The beneficial effects of the present invention are:

[0018] 1) The bottle cap of the present invention improves the bottle hanging strength of the assembly by providing a metal insert, making the assembly anti-hot pulling function. At the same time, the deformation groove is provided to reduce the strength of the lower sleeve. As long as the bottle cap is pulled, the lower sleeve will deform at the deformation groove, thereby destroying the appearance of the lower sleeve and achieving an intuitive anti-counterfeiting function.

[0019] 2) The fastening strength of the threaded connection between the inner cover and the component is ensured by providing a hard connection part. At the same time, the soft sealing part has a good sealing effect and a certain elastic deformation, which can prevent the sealing part from being crushed during assembly; multiple functions are achieved through one component of the inner cover.

[0020] 3) When the outer cap and inner cap are pressed together, the inclined surface acts as a guide, facilitating assembly. The inner cap and the assembly are connected by a stepped thread. As the cap opens, the contact area decreases, reducing friction and torque. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0032] See Figures 1-9 , the present invention provides a technical solution:

[0033] Example:

[0034] like Figures 1-9As shown, a multifunctional, heat-resistant bottle cap includes an assembly 1 and a lower sleeve 2. The lower sleeve 2 is disposed outside the assembly 1. The lower end of the assembly 1 is engaged with the lower end of the lower sleeve 2 via a hook. The assembly 1 also includes a metal insert 3 disposed between the inner and outer walls of the assembly 1. The inner wall of the lower end of the lower sleeve 2 is provided with at least one deformation groove 4. The deformation groove 4 is used to deform the edge of the lower sleeve 2 at the deformation groove 4 when the bottle cap is pulled. The deformation groove 4 is located below the hook.

[0035] The metal insert 3 includes a metal sleeve 5 , which is evenly provided with a plurality of notches 6 along the circumference. A metal clip 7 with an upper end inclined toward the center of the metal sleeve 5 is provided on the bottom edge of the notch 6 .

[0036] like Figure 2 and Figure 3 As shown, the top edge of the metal sleeve 5 is folded inward to form a pressing platform to press on the component 1, and the bottom edge of the metal sleeve 5 is folded outward to form a tensioning portion 8.

[0037] The portion of the metal sleeve 5 below the metal clip 7 is disposed between the inner wall and the outer wall of the component 1 , and the portion of the metal sleeve 5 above the metal clip 7 is exposed outside the component 1 .

[0038] The metal insert 3 is integrally formed with the component 1 by in-mold injection molding.

[0039] Among them: 1. The transparent bottle mouth adopts a combination of transparent plastic and metal semi-encapsulation, which has higher strength and lower difficulty in injection molding; that is, the aforementioned "metal sleeve 5 is arranged between the inner wall and the outer wall of the component 1 below the metal flap 7, and the metal sleeve 5 is exposed to the component 1 above the metal flap 7". 2. The plastic part adopts a special plastic that is resistant to high temperatures of 100-200°C, which can be but not limited to PTFE. 3. After the metal insert 3 is integrally formed with the component 1 by in-mold injection molding, the metal flap 7 on the metal insert 3 is wrapped in plastic to form a double-layer structure with a metal clip plate inside and a plastic claw outside the component 1. In this way, the strength of the component 1 can be improved on the basis of realizing the anti-heat-pulling function of the component 1. 4. The metal insert 3 is made of a single metal or alloy.

[0040] Working principle: When the bottle cap is heated, the metal insert 3 is provided inside the component 1, and the strength of the metal insert 3 is not easy to soften compared with the plastic component 1 after heating, thereby keeping the metal clip 7 in the bottle hanging state, preventing the bottle cap from being pulled out as a whole during heating.

[0041] At the same time, due to the presence of the deformation groove 4, the strength of the lower cover 2 is reduced at the deformation groove 4. When the bottle cap is pulled outward by force, the lower cover 2 is deformed at the deformation groove 4, thereby achieving an anti-counterfeiting effect of destroying the appearance.

[0042] The bottle cap of the present invention improves the bottle hanging strength of the component 1 by providing a metal insert 3, so that the component 1 has an anti-heat pulling function. At the same time, the strength of the lower sleeve 2 is reduced by providing a deformation groove 4. As long as the bottle cap is subjected to a pulling effect, the lower sleeve 2 will be deformed at the deformation groove 4, thereby destroying the appearance of the lower sleeve 2, thereby realizing an intuitive anti-counterfeiting function.

[0043] Furthermore, if Figure 2 、 Figure 4 、 Figure 8 and Figure 9 As shown, it also includes an outer cover 9 and an inner cover 10, wherein the outer cover 9 is arranged outside the inner cover 10, and the inner cover 10 is connected to the component 1;

[0044] The inner cover 10 includes a hard connecting portion 11 and a soft sealing portion 12. The connecting portion 11 is threadedly connected to the component 1, and the sealing portion 12 seals the wine outlet of the component 1. The connecting portion 11 can be made of, but is not limited to, ABS, and the sealing portion 12 can be made of, but is not limited to, silicone.

[0045] By providing a hard connecting portion 11, the fastening strength of the threaded connection between the inner cover 10 and the component 1 is ensured. At the same time, the soft sealing portion 12 has a good sealing effect and a certain elastic deformation, which can prevent the sealing portion 12 from being crushed during assembly; multiple functions are achieved through one component 1 of the inner cover 10.

[0046] Furthermore, if Figure 2 and Figure 4 As shown, the inner cover 10 and the outer cover 9 are fastened together by a stepped hook 13 .

[0047] The stepped hook 13 includes a first boss 14 provided on the inner wall of the outer cover 9 and a second boss 15 provided on the outer wall of the inner cover 10 , wherein the two opposing surfaces of the first boss 14 and the second boss 15 are inclined structures.

[0048] With such arrangement, when the outer cover 9 and the inner cover 10 are pressed together, the inclined surface has a guiding function, which facilitates assembly.

[0049] There is a stepped thread between the inner cover 10 and the component 1. As the bottle cap is opened, the contact area of ​​the stepped thread decreases continuously, which can reduce the friction force of opening the bottle cap and lower the opening torque.

[0050] Furthermore, if Figure 6 As shown, the inner wall of the lower end of the component 1 is provided with a positioning groove 16. The positioning groove is used for positioning the metal insert and the component with the mold during injection molding.

[0051] The foregoing description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Rather, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the concept described herein through the above teachings or techniques or knowledge in the relevant field. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the appended claims.
