Description

Technical Field

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

[0002] In order to ensure the safety and integrity of liquids during transportation, they are usually stored in special containers and sealed with bottle caps. For liquid products such as alcohol, the bottle caps widely used in the market are mainly composed of plastic parts such as inner caps and inner sleeves.

[0003] However, due to the material characteristics of plastic components, they have defects such as not being resistant to high temperatures and insufficient strength, which makes it easy for the matching structure between the inner and outer plastic parts to separate in a high temperature environment, resulting in bottle caps being prone to counterfeiting phenomena such as "high-temperature cap removal" and "bottom-out cap removal", which not only destroys the sealing of the product, but also seriously disrupts the market order and brings potential risks to consumers. Summary of the invention

[0004] Based on this, it is necessary to provide a bottle cap assembly and a container to address the problem that the bottle cap is prone to counterfeiting and affects the use effect.

[0005] According to one aspect of the present application, there is provided a bottle cap assembly, comprising an inner plug, an inner cap, an inner sleeve and an appearance part;

[0029] In order to make the above objects, features and advantages of the present application more obvious and understandable, the following will describe in detail the specific embodiments of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0030] In the description of the present application, it should be understood that if there appear these terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.

[0031] In addition, if there appear these terms "first", "second", these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first", "second" may explicitly or implicitly include at least one of such features. In the description of the present application, if there appears the term "plural", the meaning of "plural" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0032] In this application, unless otherwise clearly defined and limited, if terms such as "installed", "connected", "linked", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] In this application, unless otherwise clearly defined and limited, if there is a description such as the first feature being "on" or "under" the second feature, its meaning can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature can be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0034] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0035] During the liquid transportation process, it is usually necessary to use a container for holding and seal it with a bottle cap. For liquids such as liquor, the existing bottle caps are mainly composed of plastic parts such as an inner cap and an inner sleeve. However, these plastic parts have obvious defects: they not only have poor high-temperature resistance but also insufficient strength. And in the new national standard "GB 4806.7-2023", there are clear requirements for plastic materials that come into contact with white liquor or other strong liquor products with an alcohol concentration higher than 52%. Some materials with excellent heat resistance and impact resistance are prohibited from contacting high-concentration alcohol, so they cannot be used as the inner sleeve.

[0036] These problems have led to the current situation in the liquor market where criminals take advantage of defects such as the poor strength of bottle cap plastic parts, the plastic's inability to withstand high temperatures, and the easy separation of the inner and outer plastic parts. They commit fraud through "high-temperature cap removal" (the bottle cap is easily pulled out in a high-temperature environment), "bottom-up cap removal" (it can be easily pried open at the bottom), and "packaging material recycling". This not only affects the sealing and safety of the product, but also poses potential health risks to consumers.

[0037] In summary, the present application provides a bottle cap assembly with an inner sleeve that combines two materials, which solves the problem of restrictions on usage scenarios due to different properties of different materials, meets national food safety requirements, and increases the difficulty of counterfeiting behaviors such as high-temperature capping and bottom-covering capping. The bottle cap can be damaged when it is pulled out at high temperature or by the bottom cover, so as to remind consumers that the bottle cap has been opened and prevent the recycling of packaging materials, thereby achieving the purpose of preventing counterfeiting and solving the above-mentioned problems.

[0038] See also Figure 1 , an embodiment of the present application provides a bottle cap assembly for a bottle body 5 of a container. The bottle cap assembly includes an inner plug 1, an inner cover 2, an inner sleeve 3 and an appearance part 4. Among them, the inner sleeve is used to fit tightly with the bottle mouth to form a first sealing line of defense to prevent leakage of wine. The inner cover 2 is used to cooperate with the inner sleeve to form a second sealing line of defense, further enhancing the sealing performance of the bottle cap. The inner plug 1 is used to cooperate with the inner cover 2 and the inner sleeve to play a role of sealing and anti-theft. The appearance part 4 is used to protect the inner cover 2 and the inner sleeve 3 to prevent them from being damaged during transportation and use, and to beautify the bottle cap and enhance the product image.

[0039] It is understandable that the cap of the liquor bottle is usually composed of an outer cap 41 component and an inner plug 1 component disposed inside the outer cap 41 component, which effectively plays the main roles of sealing and anti-theft. The outer cap 41 component usually includes an outer cap 41 and a jacket 42, which is presented on the outside of the liquor bottle cap; the inner plug 1 component usually includes an inner plug 1 and an inner plug 1 seal, which can only be observed after the outer cap 41 is opened or destroyed.

[0040] See also Figure 1 and Figure 2 In the specific setting, one axial side of the inner sleeve 3 is sleeved on the inner plug 1, and is configured to press the inner plug 1 into the bottle mouth of the bottle body 5, and the other axial side of the inner sleeve 3 is accommodated in the inner cover 2 and connected to the inner cover 2, the inner plug 1, the inner cover 2, and the inner sleeve 3 together constitute the inner plug 1 assembly, and the inner cover 2 and the inner sleeve 3 together constitute the inner plug 1 seal.

[0041] Specifically, the inner kit 3 has a channel 34 for liquid circulation. The inner plug 1 is arranged in the channel 34 and is coaxially communicated with the channel 34. When the inner plug 1 is pressed into the mouth of the bottle body 5 driven by the inner kit 3, the inner kit 3 is sleeved on the bottle lip of the bottle body 5 to closely cooperate with the bottle lip, improving the sealing effect. In addition, anti-rotation ribs are usually designed on the inner sleeve, which cooperate with the anti-rotation teeth on the bottle mouth to limit the radial rotation of the inner sleeve and ensure the stability of the inner sleeve during use.

[0042] The inner cap 2 includes a cap body 21 and a sealing ring 22. The sealing ring 22 is arranged inside the cap body 21 and cooperates with the inner circumferential surface of the cap body 21 to enclose a sealing space. The other axial side of the inner kit 3 is received in the sealing space, and the inner circumferential surface of the channel 34 of the first inner sleeve 31 abuts against the outer circumferential surface of the sealing ring 22. The outer circumferential surface of the second inner sleeve 32 is threadedly connected to the inner circumferential surface of the cap body 21, so as to realize the detachable connection and sealing between the inner kit 3 and the inner cap 2 at the same time.

[0043] Refer to Figure 1 、 Figure 2 and Figure 5 As shown in, the inner kit 3 includes a first inner sleeve 31 and a second inner sleeve 32 made of different materials. The two axial sides of the first inner sleeve 31 are respectively connected to the inner plug 1 and the inner cap 2. The first inner sleeve 31 has a channel 34 for liquid circulation. The second inner sleeve 32 is arranged around the outer circumferential surface of the first inner sleeve 31 and has a claw portion 33 that can be engaged with the bottle body 5. The appearance part 4 is arranged around the outer circumferential surfaces of the inner cap 2 and the second inner sleeve 32.

[0044] It can be understood that in the embodiment of the present application, the first inner sleeve 31 that is connected to the inner plug 1 and the inner cap 2 and has a channel 34 for liquid circulation can be made of a food-grade material, so that the inner kit 3 does not affect the contact with the liquid during use and meets the national food safety requirements. The second inner sleeve 32 connected to the appearance part 4 can be made of a material with excellent heat resistance and impact resistance but prohibited from contacting the liquid to be contained, so that the inner kit 3 is not easily pulled out.

[0045] More specifically, since the inner circumferential surface of the second inner sleeve 32 has a claw portion 33 that can be engaged with the bottle lip of the bottle body 5, when the bottle cap assembly is assembled on the bottle body 5, the claw portion 33 is engaged with the bottle lip. When the bottle cap assembly is forcibly pulled out, the claw portion 33 engaged with the bottle lip will drive the second inner sleeve 32 to deform, so that the appearance part 4 deforms under the extrusion of the deformation, reminding the consumer that the bottle cap assembly has been opened, preventing packaging material recycling, etc., and achieving the purpose of preventing counterfeiting.

[0046] In addition, the tensile strength of the second inner sleeve 32 is greater than that of the bottle mouth of the bottle body 5, so that when the bottle cap assembly is forcibly pulled out, the claw part 33 can drive the bottle mouth to be damaged under the action of external force, so as to remind consumers that the bottle cap assembly has been opened, prevent the recycling of packaging materials, etc., and achieve the purpose of preventing counterfeiting.

[0047] The bottle cap assembly of the present application can be applied to container bottles such as wine bottles and cosmetic bottles. In the embodiment of the present application, the bottle cap assembly is the bottle cap of a white wine bottle. The bottle cap assembly of the present application solves the problem of the limitation of different materials for different usage scenarios due to different characteristics by making the inner kit 3 composed of the first inner sleeve 31 and the second inner sleeve 32, and using different materials for the first inner sleeve 31 and the second inner sleeve 32 respectively. The first inner sleeve 31 connected to the inner plug 1 and the inner cap 2 can be made of food-grade material, which does not affect the contact with white wine and meets the national food safety requirements. The second inner sleeve 32 connected to the appearance part 4 can be made of a material with excellent heat resistance and impact resistance but prohibited from contacting high-concentration alcohol, so that the inner kit 3 is not easily pulled out, and when it is forcibly pulled out, the bottle body 5 or the appearance part 4 will be damaged, achieving the purpose of preventing counterfeiting.

[0048] In one embodiment, the material of the first inner sleeve 31 is food-grade material to ensure that the inner kit 3 does not affect the contact with white wine and meets the national food safety requirements. The material of the second inner sleeve 32 is engineering plastic or plastic alloy, so that the inner kit 3 is not easily pulled out, and when it is forcibly pulled out, the bottle body 5 or the appearance part 4 will be damaged, achieving the purpose of preventing counterfeiting.

[0049] It can be understood that considering that most of the bottle bodies of the containers currently in circulation on the market are glass bottles, the second inner sleeve 32 made of engineering plastic or plastic alloy not only has a tensile strength higher than that of the bottle mouth of the glass bottle, but also is heat-resistant, so it can effectively prevent the bottle cap assembly from being pulled out by high-temperature heating or bottom-up pulling.

[0050] Specifically, the material of the second inner sleeve 32 is polycarbonate. Through the excellent heat resistance and impact resistance of polycarbonate, the stability of the inner kit 3 is further ensured, so that the inner kit 3 is not easily pulled out, and when it is forcibly pulled out, the bottle mouth of the bottle body 5 can be broken under the clamping of the second inner sleeve 32, or the appearance part 4 can be deformed under the extrusion of the second inner sleeve 32, so as to cause damage to the bottle cap or the bottle body 5, remind consumers that the bottle cap has been opened, prevent the recycling of packaging materials, and achieve the purpose of preventing counterfeiting.

[0051] Refer to Figure 1, in one embodiment, the appearance part 4 includes an outer cover 41 and an outer sleeve 42. The outer sleeve 42 is sleeved on the second inner sleeve 32 and is connected to the second inner sleeve 32 in a snap-fit manner. The tensile strength of the outer sleeve 42 is less than that of the second inner sleeve 32, so that when the bottle cap assembly is forcibly pulled out, the appearance part 4 can be deformed under the extrusion of the second inner sleeve 32. The outer cover 41 is sleeved on the outer sleeve 42 and the inner cap 2 and is connected to the inner cap 2 in a snap-fit manner. The user can drive the inner cap 2 to be removed from the inner kit 3 by rotating the outer cover 41 to open the bottle cap assembly.

[0052] In addition, an anti-theft structure is designed between the outer cover 41 and the outer sleeve 42, such as a buckle, a pull ring or a frangible ring, etc. These structures will be damaged when the bottle cap assembly is opened, thus playing a role in anti-theft and anti-counterfeiting, preventing the bottle cap from being illegally opened and reused, and ensuring the integrity and safety of the product.

[0053] In one embodiment, the inner peripheral surface of the first inner sleeve 31 abuts against the outer peripheral surface of the inner plug 1, and the inner peripheral surface of the second inner sleeve 32 abuts against the outer peripheral surface of the inner plug 1. Specifically, a part of the outer peripheral surface of the inner plug 1 abuts against the inner peripheral surface of the first inner sleeve 31, and another part of the outer peripheral surface of the inner plug 1 abuts against the inner peripheral surface of the second inner sleeve 32, so that the second inner sleeve 32 with excellent impact resistance can cooperate with the first inner sleeve 31 with general impact resistance to realize the press-fitting of the inner plug 1 at the bottle mouth of the bottle body 5 and ensure the press-fitting effect.

[0054] More specifically, a part of the outer peripheral surface of the second inner sleeve 32 is threadedly connected to the inner cap 2, and another part of the outer peripheral surface of the second inner sleeve 32 is connected to the outer sleeve 42 in a snap-fit manner. When the bottle cap assembly is forcibly pulled out by pulling the outer cover 41, the inner cap 2 can give a pulling force to the second inner sleeve 32, and the claw part 33 of the second inner sleeve 32 engaged with the bottle lip will drive the second inner sleeve 32 to deform, so that the outer sleeve 42 is deformed under extrusion, reminding the consumer that the bottle cap assembly has been opened, preventing the recycling of packaging materials, etc., and achieving the purpose of preventing counterfeiting.

[0055] In one embodiment, the first inner sleeve 31 and the second inner sleeve 32 are an integrally injection-molded structure. Integral injection molding can manufacture parts with extremely strict tolerances and consistent dimensions, ensuring that each part meets precise specifications. Injection-molded parts exhibit excellent structural integrity and performance in terms of wear resistance, impact resistance and resistance to environmental factors due to their uniform material distribution.

[0056] Specifically, the first inner sleeve 31 can be injection-molded from a first material, and the second inner sleeve 32 is injection-molded on the first inner sleeve 31 with a second material to form the inner kit 3. More specifically, refer to Figures 3 - 5, The specific injection molding process can be as follows: First, use the first material to inject and form the first inner sleeve 31 in the first cavity of the two-color injection molding machine. Then, rotate the mold by a preset angle, so as to transfer the first inner sleeve 31 formed by injection molding in the first cavity to the second cavity with a larger space. Then, inject the second material into the second cavity to form the second inner sleeve 32 on the first inner sleeve 31, thereby preparing the inner sleeve 3 of the bottle cap assembly.

[0057] In one embodiment, the first inner sleeve 31 and the second inner sleeve 32 are connected by snap-fit. The snap-fit connection facilitates the disassembly and replacement of the first inner sleeve 31 and the second inner sleeve 32, reducing the maintenance cost and time. In addition, compared with the integral injection molding structure, the snap-fit connection molding does not require a complex injection mold, and the mold cost is significantly lower than that of integral injection molding, which is more cost-effective in small batch production.

[0058] Specifically, the first inner sleeve 31 can be injection molded from the first material, and the second inner sleeve 32 is injection molded from the second material and is snap-fitted with the first inner sleeve 31. More specifically, the second inner sleeve 32 has an annular side wall inside, and a first snap-fit structure is provided on the annular side wall. A second snap-fit structure is provided on the outer peripheral surface of the first inner sleeve 31. The first inner sleeve 31 is sleeved on the second inner sleeve 32, and the outer peripheral surface of the first inner sleeve 31 is attached to the annular side wall of the second inner sleeve 32, and the first snap-fit structure is engaged with the second snap-fit structure.

[0059] It can be understood that in some embodiments, the first snap-fit structure is a block structure, and the second snap-fit structure is a groove structure. In other embodiments, the first snap-fit structure is a groove structure, and the second snap-fit structure is a block structure.

[0060] Refer to Figure 1 , According to another aspect of the present application, a container is provided, which includes a bottle body 5 and a bottle cap assembly as described in any one of the above embodiments. The bottle cap assembly is arranged at the bottle mouth of the bottle body 5. Specifically, the bottle cap assembly includes an inner plug 1, an inner cap 2, an inner sleeve 3, and an outer appearance part 4.

[0061] When specifically arranged, the inner plug 1 is press-fitted into the bottle mouth of the bottle body 5. One axial side of the inner sleeve 3 is sleeved on the inner plug 1, and the other axial side of the inner sleeve 3 is accommodated in the inner cap 2 and is connected to the inner cap 2. The inner sleeve 3 includes a first inner sleeve 31 and a second inner sleeve 32 made of different materials. The two axial sides of the first inner sleeve 31 are respectively connected to the inner plug 1 and the inner cap 2. The first inner sleeve 31 has a channel 34 for liquid to flow through. The second inner sleeve 32 is disposed around the outer peripheral surface of the first inner sleeve 31. A claw portion 33 is provided on the inner peripheral surface of the second inner sleeve 32, and the claw portion 33 is engaged with the bottle lip of the bottle body 5. The outer appearance part 4 is disposed around the outer peripheral surfaces of the inner cap 2 and the second inner sleeve 32.

[0062] The bottle cap assembly of the present application is formed by combining an inner kit 3 with a first inner sleeve 31 and a second inner sleeve 32. By using different materials for the first inner sleeve 31 and the second inner sleeve 32 respectively, the first inner sleeve 31 that is connected to the inner plug 1 and the inner cap 2 and has a channel 34 for liquid circulation can be made of food-grade material, so that the inner kit 3 does not affect contact with the liquid during use and meets the national food safety requirements. The second inner sleeve 32 that is connected to the appearance part 4 can be made of a material with excellent heat resistance and impact resistance but prohibited from contacting the liquid to be contained, making the inner kit 3 not easily pulled out.

[0063] In addition, since the claw part 33 of the second inner sleeve 32 is engaged with the bottle lip of the bottle body 5, when the bottle cap assembly is forcibly pulled out, the claw part 33 engaged with the bottle lip will drive the second inner sleeve 32 to deform, so that the appearance part 4 will deform under the extrusion of the deformation, reminding the consumer that the bottle cap assembly has been opened, preventing the recycling of packaging materials, etc., and achieving the purpose of preventing counterfeiting. The tensile strength of the second inner sleeve 32 is greater than the tensile strength of the bottle mouth of the bottle body 5, so that when the bottle cap assembly is forcibly pulled out, the claw part 33 can drive the bottle mouth to be damaged under the action of external force, thereby reminding the consumer that the bottle cap assembly has been opened, preventing the recycling of packaging materials, etc., and achieving the purpose of preventing counterfeiting.

[0064] The bottle body 5 of the container of the present application can be a wine bottle, a cosmetic bottle, etc. In the embodiment of the present application, the bottle body 5 is a wine bottle. For the container of the present application, by making the inner kit 3 of the bottle cap assembly composed of a first inner sleeve 31 and a second inner sleeve 32, and using different materials for the first inner sleeve 31 and the second inner sleeve 32 respectively, the problem of the limitation of different materials for different usage scenarios is solved. The first inner sleeve 31 connected to the inner plug 1 and the inner cap 2 can be made of food-grade material, which does not affect contact with white liquor and meets the national food safety requirements. The second inner sleeve 32 connected to the appearance part 4 can be made of a material with excellent heat resistance and impact resistance but prohibited from contacting high-concentration alcohol, making the inner kit 3 not easily pulled out, and when it is forcibly pulled out, the bottle body 5 or the appearance part 4 will be damaged, achieving the purpose of preventing counterfeiting.

[0065] In one embodiment, the material of the first inner sleeve 31 of the bottle cap assembly is food-grade material to ensure that the inner kit 3 does not affect contact with white liquor and meets the national food safety requirements. The material of the second inner sleeve 32 of the bottle cap assembly is engineering plastic or plastic alloy, making the inner kit 3 not easily pulled out, and when it is forcibly pulled out, the bottle body 5 or the appearance part 4 will be damaged, achieving the purpose of preventing counterfeiting.

[0066] It can be understood that considering that most of the bottle bodies of the containers currently in circulation on the market are glass bottles, the second inner sleeve 32 made of engineering plastic or plastic alloy not only has a tensile strength higher than that of the bottle mouth of the glass bottle, but also is heat-resistant, so it can effectively prevent the bottle cap assembly from being pulled out by high-temperature heating or bottom-up pulling.

[0067] Specifically, the material of the second inner sleeve 32 of the bottle cap assembly is polycarbonate. Due to the excellent heat resistance and impact resistance of polycarbonate, the stability of the inner sleeve 3 is further ensured, making it difficult to pull out the inner sleeve 3. When it is forcibly pulled out, the bottle mouth of the bottle body 5 can be broken under the clamping of the second inner sleeve 32, or the appearance part 4 can be deformed under the extrusion of the second inner sleeve 32, resulting in the damage of the bottle cap or the bottle body 5, reminding consumers that the bottle cap has been opened, preventing the recycling of packaging materials, and achieving the purpose of preventing counterfeiting.

[0068] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0069] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
