Description

Technical Field

[0001] The utility model relates to a container sealing cover, in particular to a cover assembly with good anti-counterfeiting effect. Background Art

[0002] For many containers, especially those filled with more valuable solutions, such as more expensive wines or beverages, not only are the solutions valuable but the containers are also of high value. When the solution in the container is used up, it will be recycled by some lawless elements and refilled as inferior products, causing damage to the interests of consumers and disrupting the market.

[0003] For this reason, many original manufacturers will set corresponding anti-counterfeiting marks on the container packaging.

[0039] The following is combined with Figure 1-7 The implementation modes of the present utility model are described in detail. Example

[0040] like Figure 1-5 As shown, the utility model is a cap assembly with good anti-counterfeiting effect, comprising a base 1, an upper cover 2 is connected to the upper part of the base 1, a liquid outlet 3 is provided on the base 1, an anti-counterfeiting assembly 4 is provided on the liquid outlet 3, the anti-counterfeiting assembly 4 comprises an anti-counterfeiting tray 41 connected to the liquid outlet 3, and an anti-counterfeiting member 42 is provided on the anti-counterfeiting tray 41, which can move outwards when subjected to external force to prevent the anti-counterfeiting assembly 4 from being taken out of the container mouth; the cap assembly also includes a top-pressing linkage mechanism 5 for causing the anti-counterfeiting member 42 to move outwards when used for the first time. When the utility model is used for the first time, the top cover causes the anti-counterfeiting member to move outwards through the top-pressing linkage mechanism, so that the anti-counterfeiting assembly as a whole gradually increases in the radial direction, thereby preventing the anti-counterfeiting assembly from being taken out of the container mouth, and has the characteristics of being easy to use and having good anti-counterfeiting effect.

[0041] The utility model arranges the anti-counterfeiting tray on the liquid outlet pipe and below the anti-counterfeiting piece, so that the anti-counterfeiting tray can prevent the anti-counterfeiting piece from moving downward relative to the liquid outlet pipe and can only move to both sides.

[0042] like Figure 2 As shown, when the utility model leaves the factory (before first use), the upper cover is pressed together with the anti-counterfeiting assembly through the pressing linkage mechanism, the sealing ball, the driving seat, the anti-counterfeiting ball and the anti-counterfeiting assembly to ensure that each component in the cover assembly is fixed relative to the base, avoiding damage caused by collision between the components and extending the service life.

[0043] like Figure 3 As shown, after the utility model is used for the first time, the upper cover is pressed and matched with the anti-counterfeiting component through the pressing linkage mechanism, the sealing ball, and the driving seat.

[0044] like Figure 1-5 As shown, a guide structure 6 for guiding the moving path of the anti-counterfeiting member 42 is provided between the anti-counterfeiting member 42 and the liquid outlet pipe 3, and the guide structure 6 includes a guide window provided on the liquid outlet pipe 3 and used for the anti-counterfeiting member 42 to slide and guide therein. The utility model facilitates the anti-counterfeiting member to move outward stably and smoothly along the radial direction of the liquid outlet pipe through the cooperation between the anti-counterfeiting member and the guide window.

[0045] like Figure 1-5 As shown, the anti-counterfeiting member 42 includes an anti-counterfeiting baffle 421 connected to the anti-counterfeiting tray 41, and an anti-counterfeiting protrusion 422 is provided on the outer wall of the anti-counterfeiting baffle 421, and the anti-counterfeiting protrusion 422 cooperates with the guide window. In the utility model, when the anti-counterfeiting protrusion 422 moves outward to a preset position, the outer wall of the anti-counterfeiting baffle 421 cooperates with the inner wall of the liquid outlet pipe to prevent the anti-counterfeiting protrusion from falling out of the guide window, ensuring normal use, and also making the connection between the anti-counterfeiting member and the liquid outlet pipe stable and reliable (the outer wall of the anti-counterfeiting baffle 421 fits with the inner wall of the liquid outlet pipe to increase the contact area between the anti-counterfeiting member and the liquid outlet pipe).

[0046] like Figure 2-4 As shown, in order to prevent the anti-counterfeiting member from moving inwards and resetting during use and ensure the anti-counterfeiting effect, a driving seat 7 is movably provided on the inner side of the liquid outlet pipe 3 for driving the anti-counterfeiting member 42 to move outwards and for preventing the anti-counterfeiting member 42 from moving inwards and resetting when the anti-counterfeiting member 42 moves outwards to a preset position. The driving seat 7 can be linked to a corresponding action by the top-pressing linkage mechanism 5, which is convenient for operation and use.

[0047] like Figure 2-5 As shown, in order to prevent the driving seat 7 from interfering with the anti-counterfeiting member 42 and affecting the use, a guide slope 71 is provided at the lower part of the driving seat 7. In other embodiments, the inner end of the anti-counterfeiting member 42 is provided with a guide slope that cooperates with the driving seat 7.

[0048] like Figure 2-5As shown, the push linkage mechanism 5 includes a driving rod 51 provided on the upper cover 2 and a push rod 52 movably provided on the inner side of the liquid outlet pipe 3 and located above the driving seat 7, and the push rod 52 can be driven by the driving rod 51 to move accordingly. The driving rod 51 and the push rod 52 are connected by threaded transmission, and a rotation-stopping structure 8 for enabling the push rod 52 to move up and down relative to the liquid outlet pipe 3 is provided between the push rod 52 and the liquid outlet pipe 3 or the base 1, and the rotation-stopping structure 8 includes a fixed blocking member 81 provided on the base 1 and a dynamic blocking member 82 provided on the outer side wall of the push rod 52 and used to block and cooperate with the fixed blocking member 81. In this embodiment, the driving rod 51 and the push rod 52 are connected by reverse threaded transmission, and the upper cover 2 and the base are connected by forward threaded transmission. When in use, the upper cover drives the pressing rod 52 to rotate relative to the base through the driving rod 51. At this moment, the pressing rod 52 can only move downward under the action of the anti-rotation structure 8, and the lower end of the pressing rod 52 presses the anti-counterfeiting ball 10 downward through the sealing ball 32 and the driving seat 7, and the anti-counterfeiting ball 10 acts on the anti-counterfeiting part 42 to move outward. When the lower end of the anti-counterfeiting ball 10 conflicts with the anti-counterfeiting tray 41 and forces the anti-counterfeiting tray 41 to separate from the anti-counterfeiting part 42 (the anti-counterfeiting tray still remains connected to the liquid outlet pipe and does not fall into the container cavity), the anti-counterfeiting part 41 is acted upon by the driving seat 7 to continue to move outward (or the driving seat 7 moves between multiple adjacent anti-counterfeiting parts 42 to prevent the anti-counterfeiting part 42 from moving inward and resetting, that is, the anti-counterfeiting part 42 has moved outward to the preset position), and the driving seat 7 continues to press the anti-counterfeiting tray 41 through the anti-counterfeiting ball 10 until the anti-counterfeiting tray 41 is separated from the liquid outlet pipe 3 and the anti-counterfeiting tray 41 and the anti-counterfeiting ball 10 fall into the container cavity.

[0049] In this embodiment, in order to make the overall structure of the cover assembly more compact and reduce the overall length of the cover assembly in the vertical direction, the push rod can be movably mounted on the driving rod.

[0050] like Figure 2-5 As shown, in order to prevent the push rod 52 from separating from the driving rod 51 and affecting normal use, a limiting structure 9 is provided between the push rod 52 and the driving rod 51 to prevent the push rod 52 from separating from the driving rod 51. The push rod 52 is sleeved on the driving rod 51; the limiting structure 9 includes a limiting column movably provided on the driving rod 51, and the lower end of the limiting column is blocked and matched with the driving rod 51.

[0051] like Figure 3As shown, in order to cooperate with the anti-counterfeiting part to achieve a dual anti-counterfeiting effect and further improve the anti-counterfeiting effect, the anti-counterfeiting tray 41 is connected to the anti-counterfeiting part 42, and the anti-counterfeiting tray 41 is configured to be able to be separated from the anti-counterfeiting part 42 by the top pressure linkage mechanism 5 when the anti-counterfeiting part 42 moves outward to a preset position, and then the anti-counterfeiting tray falls into the inner cavity of the container. At this time, the container can be shaken to make the anti-counterfeiting tray collide with the inner wall of the container to produce a sound, and the user can understand whether the container has been opened and used according to whether there is a collision sound in the inner cavity of the container.

[0052] like Figure 2-5 As shown, in order to improve the anti-counterfeiting effect, an anti-counterfeiting ball 10 is provided inside the liquid outlet pipe 3 , and the anti-counterfeiting ball 10 is located between the anti-counterfeiting tray 41 and the top pressing linkage mechanism 5 .

[0053] In some embodiments, the anti-counterfeiting tray 41 is made of plastic. When the anti-counterfeiting tray 41 and the anti-counterfeiting ball 10 fall into the inner cavity of the container, the main anti-counterfeiting ball 10 (glass ball, etc.) collides with the inner cavity of the container to produce a sound. The anti-counterfeiting tray 41 and the anti-counterfeiting member 42 can be integrally injection molded or separately manufactured.

[0054] In addition, the anti-counterfeiting tray 41 is made of non-plastic materials (such as glass, metal, etc.). At this time, after the anti-counterfeiting tray 41 and the anti-counterfeiting ball 10 fall into the inner cavity of the container, the anti-counterfeiting tray 41 and the anti-counterfeiting ball 10 collide with the inner cavity of the container to produce a sound. Among them, the anti-counterfeiting tray 41 and the anti-counterfeiting member 42 are manufactured separately.

[0055] like Figure 2-5 As shown, a lower positioning arc surface 101 for positioning the anti-counterfeiting ball 10 is formed between the plurality of anti-counterfeiting parts 42, and an upper positioning arc surface 102 for positioning the anti-counterfeiting ball 10 is formed at the lower end of the driving seat 7, which can ensure that the anti-counterfeiting ball 10 is relatively stable.

[0056] like Figure 2 , 3 As shown, in order to improve the sealing effect and realize automatic blocking, a liquid outlet 31 is provided inside the liquid outlet pipe 3 and between the upper and lower openings of the liquid outlet pipe 3, and a sealing ball 32 for blocking the liquid outlet 31 is movably provided inside the liquid outlet pipe 3 and above the liquid outlet 31.

[0057] like Figure 1-5 As shown, in order to ensure that the liquid in the inner cavity of the container is poured out cleanly, a side wall window 33 for connecting the inner cavity of the liquid outlet pipe 3 with the outside is provided on the side wall of the liquid outlet pipe 3 and below the liquid outlet 31 . Example

[0058] The difference between Example 2 and Example 1 is that Figure 6 , 7As shown, the pressing linkage mechanism 5 includes a pressing rod 52 movably arranged inside the liquid outlet pipe 3 and located above the driving seat 7 .

[0059] like Figure 6 , 7 As shown, for the convenience of resetting, a resetting member 521 for driving the push rod 52 to elastically reset is provided between the base 1 or the liquid outlet pipe 3 and the push rod 52 .

[0060] like Figure 6 , 7 As shown, the inner side of the liquid outlet pipe 3 is connected to a sliding tube 30 which can slide up and down and has an open upper end and a blocked lower end. A liquid outlet control structure for controlling the connection or isolation between the inner cavity of the sliding tube 30 and the inner cavity of the container is provided between the sliding tube 30 and the liquid outlet pipe 3. In this embodiment 2, the liquid outlet control structure includes a movable liquid outlet window provided on the side wall of the sliding tube and a fixed liquid outlet window provided on the side wall of the elastic member (silicone connecting sleeve) and aligned or misaligned with the movable liquid outlet window. Among them, the fixed liquid outlet window can be directly connected to the inner cavity of the container, or connected to the inner cavity of the container through the side wall window 33.

[0061] like Figure 6 , 7 As shown, the liquid outlet 31 is located inside the sliding tube 30 , and the sealing ball 32 is located inside the sliding tube 30 and above the liquid outlet 31 .

[0062] For the specific structure of this embodiment 2, please refer to: a convenient-to-use cover assembly with application number 2024210521748 submitted by the applicant on May 14, 2024; a convenient-to-use inner cover assembly with application number 201910177591.2 submitted on March 9, 2019, etc.

[0063] The use principle of the embodiment 2 is as follows: the user presses the push rod 52 to slide downward relative to the liquid outlet tube 2, and the lower end of the push rod 52 pushes the driving seat 7 and the anti-fake ball 10 to move the anti-fake part 42 outward, which is convenient to use.
