Description

Technical Field

[0001] This invention relates to container caps, and more particularly to a cap assembly with multiple functions. Background Technology

[0002] Many containers, especially those containing expensive solutions such as fine wines or beverages, are not only valuable in themselves but also in their containers. Once the solution in these containers is used up, they are often recycled by unscrupulous individuals who refill them with inferior products, thus harming consumers' interests and disrupting the market.

[0003] Therefore, many original manufacturers will set corresponding anti-counterfeiting labels on the packaging of containers. However, these anti-counterfeiting labels cannot prevent criminals from reusing empty containers for secondary or even multiple refills.

[0004] In addition, currently on the market, containers are used in conjunction with anti-counterfeiting cap components to make the containers anti-counterfeiting. When in use, the user breaks the anti-counterfeiting component on the cap component and drops it into the container cavity to achieve anti-counterfeiting. However, when the cap component is separated from the container opening, the container outlet opens, causing the anti-counterfeiting component that fell into the container cavity to flow out, thus failing to guarantee the container's anti-counterfeiting function.

[0005] Therefore, this invention addresses the aforementioned problems. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multifunctional cap assembly that can improve the problems existing in the prior art.

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1-10 The embodiments of the present invention will be described in detail. Example 1

[0028] like Figure 1-5 As shown, this invention provides a multifunctional cap assembly, including a hollow base 1 with openings at the top and bottom. The lower end of the base 1 is connected to the opening of a container. A deformable anti-counterfeiting sleeve 2, capable of extending into the container's inner cavity, is connected to the lower opening of the base 1. The anti-counterfeiting sleeve 2 has a cross-section that is wider at the top and narrower at the bottom, and is provided with a first liquid outlet hole 21 that connects the container's inner cavity to the upper opening of the base 1. A first sealing ball 22, movably disposed within the anti-counterfeiting sleeve 2, is used to open or block the first liquid outlet hole 21. An anti-counterfeiting element 3 is provided on the anti-counterfeiting sleeve 2, which can move outward under external force to prevent the anti-counterfeiting sleeve 2 from being removed from the container opening. An upper cover 4 or a tearable sealing element is connected to the upper opening of the base 1. In use, the upper cover is first separated from the base to open the upper opening of the base, as shown... Figure 2 As shown, next, rotate the base so that the opening on the base tilts downwards, as... Figure 3 As shown, during this process, the first sealing ball rolls towards the opening on the base due to its own gravity, opening the first liquid outlet. The liquid inside the container can then flow out through the first liquid outlet and the opening on the base. When the required amount is poured out, the base is flipped to reset the opening on the base. During this process, the first sealing ball, due to its own gravity, blocks the first liquid outlet, thus isolating the container's interior from the opening on the base. Figure 2 As shown, the present invention can open or block the first liquid outlet hole in a timely and automatic manner, with good sealing performance, convenient use, and reasonable design.

[0029] This invention prevents counterfeit sleeves from extending into the container cavity, such as... Figure 1 , 2 As shown, the liquid inside the container cannot be completely poured out, leaving some residue. To completely empty the liquid from the container, the anti-counterfeiting sleeve must be detached from the lower opening of the base, allowing the lower opening to open and the anti-counterfeiting sleeve to fall into the container's interior. Figure 5 As shown, when the base is tilted, the liquid inside the container flows out through the lower and upper openings of the base. Because the anti-counterfeiting sleeve separates from the lower opening, it significantly compromises the integrity of the cap assembly, making the anti-counterfeiting effect more pronounced. Simultaneously, when the anti-counterfeiting sleeve separates from the lower opening, the anti-counterfeiting component is moved outward by external force, causing the anti-counterfeiting sleeve to enlarge as a whole. Figure 4As shown, this ensures that the anti-counterfeiting sleeve cannot be removed from the container opening, providing a good anti-counterfeiting effect. Additionally, this embodiment can also be designed to allow the anti-counterfeiting sleeve 2 to extend into the container's inner cavity to control the amount of liquid residue inside the container.

[0030] like Figure 1-5 As shown, to prevent the first sealing ball from rolling out of the opening on the base and falling to the ground, thus becoming contaminated or lost, a first baffle 23 is provided between the base 1 and the anti-counterfeiting sleeve 2 to restrict the first sealing ball 22 from rolling out of the opening on the base 1. In this embodiment, the first baffle 23 is located on the inner wall of the anti-counterfeiting sleeve 3.

[0031] like Figure 1-5 As shown, to improve sealing, a second liquid outlet 24 is provided between the base 1 and the anti-counterfeiting sleeve 2, which connects the first liquid outlet 21 to the opening on the base 1. A second sealing ball 25 for opening or blocking the second liquid outlet 24 is movably provided between the base 1 and the anti-counterfeiting sleeve 2. In this embodiment, the second liquid outlet 24 is located inside the anti-counterfeiting sleeve 2.

[0032] like Figure 1-5 As shown, in order to prevent the second sealing ball from rolling out of the opening on the base and falling to the ground and being contaminated or lost, a second baffle 26 is provided between the base 1 and the anti-counterfeiting sleeve 2 to limit the second sealing ball 25 from rolling out of the opening on the base 1.

[0033] like Figure 1-5 As shown, the upper cover 4 is provided with a top pressure rod 41. The lower end of the top pressure rod 41 abuts against the second sealing ball 25 to keep the second sealing ball 25 blocking the second liquid outlet 24, and the second sealing ball 25 abuts against the first sealing ball 22 to keep the first sealing ball 22 blocking the first liquid outlet 21. During storage and transportation, the top pressure rod 41 prevents the first and second sealing balls from shaking, thereby ensuring that the first and second liquid outlets are always blocked by the first and second sealing balls, ensuring airtightness.

[0034] To reduce manufacturing costs, the top pressure rod 41 and the upper cover 4 are integrally formed.

[0035] like Figure 1-5As shown, a driving component is movably provided between the base 1 and the anti-counterfeiting sleeve 2, which can drive the anti-counterfeiting component 3 to move outward along the width direction of the anti-counterfeiting sleeve 2. When the anti-counterfeiting component 3 moves outward, the driving component can drive the anti-counterfeiting sleeve 2 to detach from the base 1 and fall into the inner cavity of the container. The driving component includes a first sealing ball 22, and the lower opening edge of the anti-counterfeiting sleeve 2 is provided with a blocking part 20 for blocking the first sealing ball 22. When the liquid inside the container cannot flow out of the anti-counterfeiting sleeve and it is necessary to separate the anti-counterfeiting sleeve from the base, the user operates the first sealing ball to move downward relative to the base. During this movement, the first sealing ball drives the anti-counterfeiting component to move outward along the width direction of the anti-counterfeiting sleeve. Then, the first sealing ball 22 abuts against the blocking part 20, and the first sealing ball drives the anti-counterfeiting sleeve to move downward relative to the base, thereby causing the anti-counterfeiting sleeve to separate from the lower opening of the base and fall into the container cavity. In addition, when the anti-counterfeiting component is driven outward by the first sealing ball, the first sealing ball can also prevent the anti-counterfeiting component from moving inward relative to the anti-counterfeiting sleeve and resetting, ensuring that the anti-counterfeiting sleeve that has fallen into the container cavity cannot be taken out from the container opening.

[0036] like Figure 1-5 As shown, there are multiple anti-counterfeiting components 3, which are integrally formed on the side wall of the anti-counterfeiting sleeve 2 along the circumferential direction. The inner side wall of the anti-counterfeiting component 3 is inclined, and the inner side wall of the anti-counterfeiting component 3 and the inner wall of the blocking part 20 form a limiting space for the first sealing ball 22 to enter. When the first sealing ball enters the limiting space, it can restrict the movement of the first sealing ball relative to the anti-counterfeiting component, thereby ensuring that the first sealing ball always abuts against the inner side wall of the anti-counterfeiting component 2.

[0037] like Figure 1-5 As shown, a driving assembly is movably provided between the base 1 and the anti-counterfeiting sleeve 2, which can drive the anti-counterfeiting component 3 to move outward along the width direction of the anti-counterfeiting sleeve 2. When the anti-counterfeiting component 3 moves outward, the driving assembly can drive the anti-counterfeiting sleeve 2 to detach from the base 1 and fall into the container cavity. The driving assembly includes a first sealing ball 22 and a second sealing ball 25. The lower opening edge of the anti-counterfeiting sleeve 2 is provided with a blocking part 20 for blocking the first sealing ball 22. When the liquid in the container cavity cannot flow out of the anti-counterfeiting sleeve and it is necessary to separate the anti-counterfeiting sleeve from the base, the user operates the second sealing ball to move downward relative to the base. During this movement, the second sealing ball pushes the first sealing ball downward, thereby causing the first sealing ball to drive the anti-counterfeiting component to move outward along the width direction of the anti-counterfeiting sleeve. Figure 4 As shown, the first sealing ball 22 then abuts against the blocking part 20, causing the first sealing ball to move the anti-counterfeiting sleeve downwards relative to the base, thereby causing the anti-counterfeiting sleeve to separate from the lower opening of the base and fall into the inner cavity of the container, as shown. Figure 5 As shown. Example 2

[0038] The difference between Example 2 and Example 1 is that, as Figure 6As shown, the second liquid outlet 24 is located on the base 1 and between the upper and lower openings of the base 1. Example 3

[0039] The difference between Example 3 and Example 1 is that, as Figure 7 As shown, the anti-counterfeiting sleeve 2 is open at the top and sealed at the bottom, and the blocking part 20 is formed by the inner bottom of the anti-counterfeiting sleeve 2. The second liquid outlet 24 is provided on the base 1 and located between the upper and lower openings of the base; the first baffle 23 is provided at the lower edge of the second liquid outlet 24. Example 4

[0040] like Figure 8-10 As shown, the present invention provides a multifunctional cap assembly, including a hollow base 1 with openings at the top and bottom. The lower opening of the base 1 forms a first liquid outlet hole 21 that connects the upper opening of the base 1 to the inner cavity of a container. A first sealing ball 22 for opening or sealing the first liquid outlet hole 21 is movably provided inside the base 1. A top cover 4 or a tearable seal is connected to the upper opening of the base 1. An anti-counterfeiting component 3 that can extend into the inner cavity of the container is connected to the lower opening of the base 1. The anti-counterfeiting component 3 has an anti-counterfeiting blocking part 31 that prevents the anti-counterfeiting component 3 from being removed from the container opening after it extends into the inner cavity of the container. This prevents the anti-counterfeiting component from being removed from the container opening. If the anti-counterfeiting component needs to be removed, the container needs to be destroyed to ensure the anti-counterfeiting effect. In addition, the first sealing ball can automatically open or seal the first liquid outlet hole, providing good sealing and ease of use.

[0041] In this embodiment, the anti-counterfeiting blocking part 31 is an elastic sheet that can be elastically deformed and is provided on the periphery of the anti-counterfeiting part 3. The elastic sheet is inclined outward and upward relative to the anti-counterfeiting part.

[0042] As shown in 9 and 10, in this embodiment, the first liquid outlet 21 is blocked by the upper end of the anti-counterfeiting component 3, which further improves the sealing performance of the cover assembly before first use.

[0043] like Figure 9 As shown, to prevent the first sealing ball from rolling out of the opening on the base and falling to the ground, thus becoming contaminated or lost, the base 1 is provided with a first baffle 23 to restrict the first sealing ball 22 from rolling out of the opening on the base 1. In this embodiment, the first baffle 23 is used to prevent the first sealing ball 22 from blocking the second liquid outlet 24 during the liquid extraction process, ensuring smooth liquid discharge.

[0044] like Figure 9 , 10 As shown, in order to improve the sealing performance, the base 1 is also provided with a second liquid outlet 24 that can connect the first liquid outlet 21 with the opening on the base 1, and a second sealing ball 25 for opening or blocking the second liquid outlet 24 is movably provided in the base 1.

[0045] like Figure 9 As shown, in order to prevent the second sealing ball from rolling out of the opening on the base and falling to the ground and being contaminated or lost, the base 1 is also provided with a second baffle 26 for limiting the second sealing ball 25 from rolling out of the opening on the base 1.

[0046] like Figure 9 As shown, the upper cover 4 is provided with a top pressure rod 41. The lower end of the top pressure rod 41 abuts against the second sealing ball 25, keeping the second sealing ball 25 blocking the second liquid outlet 24. The second sealing ball 25 also abuts against the first sealing ball 22, keeping the first sealing ball 22 blocking the first liquid outlet 21. During storage and transportation, the top pressure rod 41 prevents the first and second sealing balls from shaking, thereby ensuring that the first and second liquid outlets are always blocked by the first and second sealing balls, ensuring a tight seal.

[0047] like Figure 9 , 10 As shown, a driving assembly is movably provided between the base 1 and the anti-counterfeiting component 3, which can drive the anti-counterfeiting component 3 to separate from the base 1 and fall into the inner cavity of the container. The driving assembly includes a top pressure rod 41 provided on the upper cover 4 and a top pressure sliding sleeve 42 threadedly connected to the top pressure rod 41 and capable of moving up and down relative to the base 1. In use, when the upper cover is rotated relative to the base, the top pressure rod 41 drives the top pressure sliding sleeve 42 to move downward relative to the base. The top pressure sliding sleeve 42 pushes the second sealing ball 25 and the first sealing ball 22 downward relative to the base, causing the first sealing ball 22 to push the anti-counterfeiting component 3, thereby causing the anti-counterfeiting component 3 to separate from the base 1 and fall into the inner cavity of the container. When dispensing liquid, the top cover is operated to open the opening on the base. Then, the base is flipped so that the opening on the base tilts downward. During this process, the second sealing ball rolls towards the opening on the base due to its own gravity, opening the second liquid outlet. The first sealing ball also rolls towards the opening on the base due to its own gravity, opening the first liquid outlet. The liquid inside the container can then flow out through the first liquid outlet, the second liquid outlet, and the opening on the base. When the required amount is dispensed, the base is flipped so that the opening on the base returns to its original position. During this process, the first sealing ball blocks the first liquid outlet due to its own gravity, and the second sealing ball blocks the second liquid outlet due to its own gravity, thus isolating the container cavity from the opening on the base. Therefore, this invention can open or seal the first and second liquid outlets in a timely and automatic manner, providing good sealing, ease of use, and a reasonable design.

[0048] like Figure 10 As shown, the outer wall of the top pressure sleeve 42 is provided with an anti-rotation protrusion 421 extending along its length direction, and the base 1 is provided with an anti-rotation groove 11 for the anti-rotation protrusion 421 to be inserted to prevent the top pressure sleeve 42 from rotating relative to the base 1.
