Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a one-time-opening RFID bottle cap and wine bottle. 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 CN110626629A discloses a chip-resistant bottle cap for RFID electronic anti-counterfeiting tags, comprising: an inner cap, an outer cap, and an RFID electronic tag chip. The outer cap covers and connects to the inner cap, and the outer and inner caps can rotate relative to each other, damaging both the RFID chip and the RFID antenna.

[0003] Because RFID tag data propagates via electromagnetic waves, and metal materials shield against these waves, these bottle caps are typically made of plastic. The plastic material of the caps softens easily when heated, allowing the entire cap to be removed from the bottle. Further disassembly of the cap, separating the outer and inner caps, allows for the complete removal of the RFID tag, significantly reducing its overall anti-counterfeiting effectiveness. Utility Model Content

[0004] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a one-time opening RFID bottle cap and wine bottle.

[0005] The one-time opening RFID bottle cap provided by this utility model includes: an outer cap, a connecting ring, an inner cap, and an RFID tag.

[0006] The bottle cap also includes a bottle spout.

[0007] The inner wall of the outer cover is provided with a tenon, a limiting strip, and a protrusion.

[0008] The connecting ring has a ring structure with a limiting groove A on its outer circumference and a limiting ring on one side.

[0009] The inner cover has a limiting groove B on its outer end face facing away from the opening, and a linkage post and a sliding groove on its outer peripheral surface. The linkage post is located in the sliding groove.

[0010] The inner wall of the inner cover is provided with internal threads.

[0011] The inner cap is threaded to the external thread of the bottle neck via the internal thread.

[0012] The outer wall of the bottle mouth is provided with an external thread that matches the internal thread, and the inner cap is threadedly connected to the bottle mouth.

[0013] The bottle nozzle includes a clamping device connected to the bottle mouth, which is clamped onto the outside of the bottle mouth.

[0014] The bottle mouth opening and the clamping device are equipped with anti-pull-out rings.

[0015] The anti-pull ring is made of metal.

[0016] Preferably, the metal material includes stainless steel.

[0017] And / or, the thickness of the metal material is 0.1~3mm.

[0018] The limiting ring is located inside the limiting groove B.

[0019] The RFID tag is partially connected to the inner cover and partially connected to the connecting ring.

[0020] Part of the RFID tag is connected to the side of the connecting ring facing away from the opening of the inner cover, and part of it is connected to the top of the inner cover facing away from the opening of the inner cover.

[0021] The outer cover is axially limited by a limiting strip, and the tenon is located in the limiting groove A; the protrusion is located in the sliding groove.

[0022] Preferably, a column is provided in the sliding groove of the inner cover at a position corresponding to the initial position of the protrusion.

[0023] The friction between the protrusion and the sliding groove is less than the friction between the internal thread of the inner cap and the external thread of the bottle mouth.

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 , Figure 2 and Figure 3 As shown, a one-time opening RFID bottle cap includes: an outer cap 1, a connecting ring 2, an inner cap 3, and an RFID tag 5. The inner wall of the outer cap 1 has a latch 101, a limiting strip 102, and protrusions 103, the number of which can be arbitrary, extending circumferentially along the inner wall of the outer cap 1. The connecting ring 2 is annular, with limiting grooves A201 on its outer circumferential surface, the number and position corresponding to the latch 101. One side of the connecting ring 2 has an axially extending limiting ring 202. The outer end face of the inner cap 3 has an annular limiting groove B301, the shape of which matches the limiting ring 202. The outer circumferential surface of the inner cap 3 has a linkage post 302 and a sliding groove 303, the linkage post 302 being located within the sliding groove 303.

[0031] The outer cover 1 is axially limited to the connecting ring 2 by the limiting strip 102, so that the outer periphery of the connecting ring 2 is axially limited to the inner side of the limiting strip 102. The latch 101 of the outer cover 1 is located in the limiting groove A201 of the connecting ring 2. When the outer cover 1 rotates, when the latch 101 touches the side wall of the limiting groove A201, it drives the connecting ring 2 to rotate together.

[0032] The limiting ring 202 is located in the limiting groove B301 of the inner cover 3, which radially limits the connecting ring on the top surface of the inner cover 3. The protrusion 103 of the outer cover 1 is located in the sliding groove 303. When the outer cover 1 rotates, when the protrusion 103 touches the linkage post 302 in the sliding groove 303, it drives the inner cover 3 to rotate together, thereby opening the cover.

[0033] Part of the RFID tag 5 is connected to the top of the connecting ring 2, and part is connected to the top of the inner cover 3, which can usually be achieved by adhesive bonding.

[0034] The inner wall of the inner cap 3 is provided with an internal thread 304. In this embodiment, the inner cap 3 can be directly threaded onto the external thread of the bottle mouth.

[0035] When the bottle cap is opened normally, the outer cap 1 is rotated. The outer cap 1 drives the connecting ring 2 to rotate through the latch 101 and the limiting groove A201 on the connecting ring 2. Since the sliding groove 303 is relatively long, the protrusion 103 slides in the sliding groove 303 at this time and has not yet contacted the linkage column 302. The top of the connecting ring 2 and the top of the inner cap 3 rotate relative to each other, thereby damaging the RFID tag 5.

[0036] To prevent the inner cap 3 from being directly driven by friction when rotating the outer cap 1, in this embodiment, the friction between the protrusion 103 and the sliding groove 303 is less than the friction between the internal thread 304 of the inner cap 3 and the external thread of the bottle mouth. Simultaneously, a column 305 is provided in the sliding groove 303 of the inner cap 3 at a position corresponding to the initial position of the protrusion 103 to increase the friction between the protrusion 103 and the sliding groove 303 during initial rotation, preventing the bottle cap from opening with slight force (the inner cap 3 and the bottle mouth rotate to open).

[0037] When the protrusion 103 inside the outer cap 1 contacts the linkage post 302 on the outside of the inner cap 3, the relative movement of the outer cap 1, connecting ring 2, and inner cap 3 stops. If rotation continues, the outer cap 1 drives the inner cap 3 to rotate through the protrusion 103 and linkage post 302, thereby unscrewing the bottle cap.

[0038] Example 2 like Figure 4 and Figure 5 As shown, this embodiment, based on embodiment 1, further adds a bottle nozzle 4, which connects to the bottle mouth and the inner cap 3. The outer wall of the bottle nozzle 4 is provided with an external thread 402 that matches the internal thread 304 of the inner cap 3, and the inner cap 3 is threadedly connected to the bottle nozzle 4. The bottle nozzle 4 includes a clamping device 401 for connecting with the bottle mouth, and the clamping device 401 is engaged with the outer flange portion of the bottle mouth.

[0039] Similarly, the friction between the protrusion 103 and the sliding groove 303 is less than the friction between the internal thread 304 of the inner cover 3 and the external thread 402 of the bottle mouth 4, so as to avoid the inner cover 3 being directly driven by friction when the outer cover 1 is rotated.

[0040] Considering that the inner cap 3 is made of plastic, which softens easily when heated, making it easy to pull the cap off the bottle as a whole, this embodiment also includes an anti-pull ring 403. The anti-pull ring 403 is connected to the inside of the opening end of the bottle mouth 4 and the inside of the clamping device 401. The anti-pull ring 403 is made of metal, which will not soften when heated, preferably stainless steel, with a thickness of 0.1~3mm. This prevents the bottle cap from being pulled off by heating without affecting the normal operation of the RFID tag 5.

[0041] When attempting to remove the bottle cap entirely from the bottle opening by heating it to soften it, the locking device 401 at the bottle mouth 4 below the cap is made of metal and will not soften when heated, thus preventing the cap from being pulled out. When attempting to separate the outer cap 1 from the inner cap 3, pulling the outer cap 1 upwards will pull out the connecting ring 2 as well. At this time, the RFID tag 5 attached to both the connecting ring 2 and the top of the inner cap 3 will be torn, similarly preventing the cap from being completely disassembled.

[0042] Example 3 A wine bottle includes a one-time opening RFID bottle cap as described in Embodiment 1 or Embodiment 2, the one-time opening RFID bottle cap being connected to the bottle mouth 601 of the wine bottle 6.
