Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to an RFID bottle cap and bottle that prevents unauthorized opening. Background Technology

[0002] With the booming development of the liquor market, this sector has also become a major area for counterfeiting. Therefore, most high-end liquor brands currently use bottle caps containing RFID for anti-counterfeiting. Patent document CN202765503U discloses an anti-counterfeiting bottle cap, including a liner with a main recessed groove and an inner cap with a main protrusion. The main protrusion can rotate within the main recessed groove to a certain extent. When the user opens the bottle cap, the anti-counterfeiting label is destroyed by the relative rotation of the liner and inner cap.

[0003] Because RFID tag data is transmitted via electromagnetic waves, and metal materials have a shielding effect on electromagnetic waves, the outer cap of this type of bottle cannot be made entirely of metal; most are made of plastic. Heating softens the plastic material of the bottle cap, allowing it to be removed without damage, thus enabling the complete removal of the RFID tag for reuse. Utility Model Content

Detailed Implementation

[0029] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0030] Example 1 like Figure 1 and Figure 2 As shown in the figure, this embodiment provides an RFID bottle cap to prevent abnormal opening, including: an outer cap 1, a middle part 2, an inner cap 3, and an RFID tag.

[0031] The outer cover 1 and the inner cover 3 are movably connected. The intermediate component 2 is movably connected to both the outer cover 1 and the inner cover 3. The axial bonding force between the intermediate component 2 and the inner cover 3 is less than the axial bonding force between the intermediate component 2 and the outer cover 1. Therefore, when the outer cover 1 is abnormally disassembled and removed, the intermediate component 2 will separate from the inner cover 3 along with the outer cover 1. Simultaneously, in this embodiment, the RFID tag can be disposed in the gap between the intermediate component 2, the inner cover 3, and the outer cover 1, at least partially connected to the inner cover 3 and at least partially connected to the intermediate component 2. Thus, when the intermediate component 2 separates from the inner cover 3, the RFID tag will be torn and damaged, greatly increasing the difficulty of disassembling the outer cover 1.

[0032] To ensure that the axial bonding force between the intermediate component 2 and the inner cover 3 is less than the axial bonding force between the intermediate component 2 and the outer cover 1, in this embodiment, the inner sidewall of the outer cover 1 is provided with a first limiting member 101, such as a limiting strip, and the outer sidewall of the intermediate component 2 is provided with a second limiting member 201 at a position corresponding to the first limiting member 101, such as... Figure 3 , Figure 4 As shown, the second limiting member 201 can be a limiting groove or limiting rib surrounding the outer wall of the intermediate member 2. The outer cover 1 and the intermediate member 2 are axially limited by the first limiting member 101 and the second limiting member 201, realizing a movable connection between the intermediate member 2 and the outer cover 1. Under axial limitation, the first limiting member 101 and the second limiting member 201 can rotate relative to each other. Figure 3 As shown, the second limiting member 201 uses a limiting rib to engage between the first limiting member 101 and the top surface of the outer cover 1; as Figure 4 As shown, the second limiting member 201 uses a limiting groove to engage the first limiting member 101. The outer cover 1 and the intermediate member 2 can be installed by utilizing the elasticity of the materials of the outer cover 1 and the intermediate member 2 to directly engage the first limiting member 101 of the outer cover 1.

[0033] like Figure 5 , Figure 6 , Figure 7 As shown, the connection between the intermediate component 2 and the inner cover 3 is presented in three ways in this embodiment. Method 1: As shown... Figure 5 As shown, the intermediate component 2 is a ring structure connected to the end (top) of the inner cover 3 facing the outer cover 1. The top of the inner cover 3 has a protrusion that fits the hollowed-out portion in the middle of the ring structure. The ring structure is fitted onto the protrusion to achieve horizontal positioning. The RFID tag is at least partially connected to the outer wall of the closed end of the inner cover 3 and at least partially connected to the ring structure on the same side. Methods two and three: as shown... Figure 6 , Figure 7 As shown, the intermediate piece 2 extends downwards from the top of the inner cover 3 and fits the inner cover 3 inside. The intermediate piece 2 has an opening on one side near the top of the inner cover 3, forming a barrel-shaped structure with an open top.

[0034] In order to prevent the outer cap 1 from being pulled out by heating the RFID bottle cap and softening its plastic material (especially the first limiting member 101 and the second limiting member 201), in this embodiment, the first limiting member 101 and the second limiting member 201 are made of metal, such as stainless steel, and the thickness can be set to 0.1~3mm to prevent the material from softening after being heated.

[0035] Based on the above structure, this embodiment further provides two connection methods between the RFID bottle cap and the bottle opening. Method 1: An internal thread 301 is provided on the inner sidewall of the inner cap 3, and the inner cap 3 is directly screwed onto the external thread of the bottle opening via the internal thread 301. Method 2: As... Figure 8 , Figure 9 As shown, the RFID bottle cap also includes a bottle nozzle 4, which includes a clamping device 401 connected to the bottle mouth 5. The outer wall of the bottle nozzle 4 is provided with an external thread 402 that matches the internal thread 301. The inner wall of the inner cover 3 is provided with an internal thread 301, and the inner cover 3 is screwed onto the bottle nozzle 4. In this embodiment, the clamping device 401 is clamped onto the annular structure on the outer side of the bottle mouth.

[0036] To prevent the RFID bottle cap from softening due to heating (especially the clamping device 401) and being pulled out entirely, in this embodiment, the bottle mouth 4 is also provided with an anti-pull-out ring 403. The anti-pull-out ring 403 is connected inside the opening of the bottle mouth 4 and inside the clamping device 401. The anti-pull-out ring 403 is made of metal, such as stainless steel, and its thickness can be set to 0.1~3mm to prevent the material from softening when heated.

[0037] Example 2 Based on Embodiment 1, this embodiment provides a bottle including the aforementioned RFID bottle cap to prevent unauthorized opening, which is screwed onto the external thread of the bottle mouth via the internal thread of the inner cap 3. Alternatively, the bottle mouth 4 is connected to the bottle mouth 5, and the inner cap 3 is screwed onto the bottle mouth 4.

[0038] When rotating the outer cover 1 normally, in Figure 1 , Figure 2In the middle section, a latch 103 and a protrusion 102 are provided on the inner side of the outer cover 1. During rotation, the latch 103 will first contact the side wall of the limiting groove 202 formed between the two adjacent second limiting members 201 of the middle section 2, thereby realizing the rotation of the middle section 2 by the outer cover 1. At this time, the inner cover 3 has not yet rotated, and the rotation of the middle section 2 will damage the RFID tag connecting the middle section 2 and the inner cover 3. A sliding groove 302 is provided on the outer side of the inner cover 3. The protrusion 102 is limited and slidably connected in the sliding groove 302, realizing the relative rotation between the outer cover 1 and the inner cover 3. A linkage post 303 is provided at the end of the sliding groove 302. During continued rotation, when the protrusion 102 rotates and contacts the linkage post 303, the outer cover 1 will drive the inner cover 3 to rotate synchronously, realizing the opening of the cover. In the barrel-shaped middle section 2, a protrusion that cooperates with the sliding groove 302 and linkage post 303 of the inner cover 3 is provided on the inner side of the middle section 2. This invention does not limit the scope of the invention in this regard. The principle of destroying RFID tags by rotating the bottle cap can be achieved using existing structural designs. For example, a limiting structure located in the direction of rotation can be provided between the outer cap 1 and the intermediate component 2. The intermediate component 2 rotates synchronously with the outer cap 1, and the RFID tag connected to the intermediate component 2 and the inner cap 3 will be destroyed by the rotation. Alternatively, a frosted surface with a certain roughness can be provided on the inner surface of the outer cap 1, and the RFID tag can be destroyed by the wear and tear caused by the rotation of the outer cap 1. This invention does not limit the scope of the invention in this regard.

[0039] When attempting to separate the outer cap 1 and the intermediate component 2 by heating to obtain the complete RFID tag, as the outer cap 1 is pulled upwards, because the force between the intermediate component 2 and the inner cap 3 is less than the force between the intermediate component 2 and the outer cap 1, the outer cap 1 will pull the intermediate component 2 out together. At this time, the RFID tag simultaneously attached to the top of the intermediate component 2 and the inner cap 3 will be torn. Alternatively, when heating to separate the bottle cap and the bottle to obtain the complete bottle cap structure, because the anti-pull ring 403 in the clamping device 401 below the bottle mouth 4 is made of metal, it will not soften when heated, thus preventing the bottle cap from being pulled out of the bottle mouth, thereby preventing the bottle cap from being improperly disassembled.
