Description

Technical Field

[0001] This utility model relates to the field of anti-counterfeiting technology, and in particular to a structure for a hidden anti-theft information code on a bottle cap. Background Technology

[0002] Information codes are often found on bottle caps in the market to help customers verify the authenticity of the wine, or to provide discounts for promotional purposes. However, traditional information codes are usually placed on the outside of the bottle cap, making them easy to steal. Moreover, once the anti-counterfeiting code is stolen, the bottle cap can be easily restored, concealing the traces of the theft. This allows situations where the bottle cap is restored to its original state and the wine can continue to be sold after the information code is stolen, increasing the losses for merchants. Utility Model Content

[0003] To overcome its shortcomings, the technical problem to be solved by this utility model is: how to reduce the risk of the information code on the bottle cap being stolen.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A structure for a bottle cap with a concealed anti-theft information code includes a bottom cap for connecting to the outlet of a container and a flow restrictor fitted inside the bottom cap. The outer wall of the bottom cap has a first mounting portion and a second mounting portion. A locking sleeve is fitted onto the outer side of the first mounting portion, and an inner cap is threaded onto the outer side of the second mounting portion. An information code is provided on the outer wall of the inner cap. The end of the inner cap near the first mounting portion has a first protruding edge, and the end of the locking sleeve near the second mounting portion has a second protruding edge. The end of the inner cap with the first protruding edge extends to the first mounting portion. The upper end of the locking sleeve is fitted onto the upper part of the inner cap with an interference fit, and the first and second protruding edges abut against each other, facilitating the fitting of the top cap and the locking sleeve. The upper part of the locking sleeve covers part of the information code; a top cover is sleeved on the outer side of the inner cover, and the top cover completely covers the part of the information code that is not covered by the locking sleeve; a slider is provided on the inner wall of the top cover, and a spiral groove is provided on the outer wall of the inner cover; when the top cover is rotated so that the slider slides to abut against the inner wall of the spiral groove away from the locking sleeve, the part of the information code that is not covered by the locking sleeve is exposed.

[0006] Furthermore, the lower end of the top cover is provided with a flexible snap-fit ​​edge, and a protrusion is provided on the upper side of the aforementioned information code. The snap-fit ​​edge and the aforementioned protrusion are in an interference fit.

[0007] Furthermore, the inner wall of the inner cover is provided with a first positioning block, and the outer wall of the bottom cover is provided with a second positioning block that engages with the positioning block.

[0008] Furthermore, the lower end of the top cover is provided with an elastic tightening part, and the outer wall of the inner cover is provided with an arc-shaped protrusion. The information code is set on the outer wall of the arc-shaped protrusion. The elastic tightening part and the arc-shaped protrusion are interference-fitted. When the top cover is rotated so that the slider slides to abut against the inner wall of the upper end of the spiral groove, the elastic tightening part is sleeved on the upper part of the arc-shaped protrusion.

[0009] Furthermore, the outer wall of the top cover is vertically provided with a relief groove. During assembly, the relief groove is used to cause the top cover to deform outward by applying force to the inner wall of the top cover. The upper edge of the top cover is provided with an inclined surface, and the spiral groove is located below the inclined surface. When a downward force is applied to the top cover, the top cover deforms to the circumference, and the slider slides relative to the inclined surface and continues to slide downward into the spiral groove.

[0010] Furthermore, the outer wall of the aforementioned flow restrictor is provided with a groove, and the inner wall of the aforementioned bottom cover is provided with a protrusion that engages with the aforementioned groove.

[0011] Furthermore, the top cover is provided with a positioning groove, and the inner wall of the inner cover is provided with a positioning protrusion that slides in conjunction with the positioning groove.

[0012] The beneficial effects of this utility model are:

[0013] (1) The information code is set on the outside of the inner cover, so that the top cover and the locking sleeve cover the outside of the information code. When the top cover is rotated, the slider slides upward in the spiral groove and abuts against the inner wall of the upper end of the spiral groove. The top cover moves up and exposes the upper part of the information code, but the lower part of the information code is blocked by the locking sleeve, avoiding the risk of the information code being completely exposed and stolen. Moreover, when it is necessary to open the cover normally, the top cover is rotated again. The slider acts on the inner wall of the upper end of the spiral groove. The top cover drives the inner cover to rotate synchronously, so that the inner cover moves up from the second mounting part. The first and second protrusions are elastically separated, and the lower part of the inner cover is completely separated from the locking sleeve, so that the information code can be fully displayed. At this time, the first and second protrusions abut against each other, and the outer part of the inner cover cannot be inserted into the locking sleeve again, so that the inner cover cannot be restored. This means that the information code can only be fully obtained when the cover is opened normally. During the opening process, the information code on the side of the inner cover is gradually revealed in stages, which improves the anti-counterfeiting effect.

[0014] (2) By interfering with the elastic tightening part and the arc-shaped convex plate, when the top cover moves upward until the elastic tightening part and the arc-shaped convex plate are separated, the elastic tightening part contracts elastically, and the lower end of the elastic tightening part and the upper end of the arc-shaped convex plate abut against each other, so that the top cover cannot be reset downward and the side information code is always partially displayed, further improving the anti-counterfeiting effect.

[0015] (3) By setting the clearance groove and the inclined surface, the top cover can be installed stably and properly on the outside of the inner cover. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] according to Figure 1 , Figure 2 As shown in the embodiment of this application, a structure for a bottle cap concealed anti-theft information code is proposed, including a bottom cap 5 for connecting to the container outlet and a flow restrictor 4 sleeved on the inner wall of the bottom cap 5. The outer wall of the bottom cap 5 includes a first mounting part 51 and a second mounting part 52 from top to bottom. A locking sleeve 2 is sleeved on the outer side of the first mounting part 51, and an inner cap 3 is threaded on the outer side of the second mounting part 52. An information code 34 is provided on the outer wall of the inner cap 3. A first protruding edge 31 is provided on the bottom end of the inner cap 3, and a second protruding edge 21 is provided on the upper end of the locking sleeve 2. The lower end of the inner cap 3 extends to a preset position of the first mounting part 51. The upper end of the locking sleeve 2 is sleeved on the upper position of the inner cap 3 with an interference fit, and the first protruding edge 31 and the... The second protruding edges 21 abut against each other, facilitating the assembly of the top cover 1 and the locking sleeve 2; both the first protruding edge 31 and the second protruding edge 21 are annular protrusions 38, which, after being engaged with each other, cannot be disengaged within a certain range of force; the upper part of the locking sleeve covers part of the information code 34, ensuring the stability of the information code 34 in the covered state; the top cover 1 is sleeved on the outer side of the inner cover 3, and the top cover 1 completely covers the part of the information code 34 that is not covered by the locking sleeve 2; the inner wall of the top cover 1 is provided with a slider 12, and the outer wall of the inner cover 3 is provided with a spiral groove 32 extending from bottom to top; when the top cover 1 is rotated so that the slider 12 slides to abut against the inner wall of the upper end of the spiral groove 32, the part of the information code 34 that is not covered by the locking sleeve 2 is not covered.

[0021] Specifically, the bottom cover 5 is generally fixedly fitted onto the outlet of the container, such as the mouth of a wine bottle. The flow restrictor 4 is an existing flow restrictor outlet structure. The outer wall of the flow restrictor 4 is provided with a groove 41, and the inner wall of the bottom cover 5 is provided with a protrusion 38 that engages with the groove 41 to ensure the installation stability of the flow restrictor 4. The first mounting part 51 and the second mounting part 52 are connected vertically and together form the outer wall of the bottom cover 5. During the installation process, the inner cover 3 is first threadedly fitted onto the upper second mounting part 52, and then the locking sleeve 2 is fitted onto the first mounting part 51, so that the upper part of the locking sleeve 2 is interference-fitted onto the lower part of the inner cover 3 and partially covers the information code 34. At this time, the first protrusion 31 and the second protrusion 21 abut against each other. Then, the top cover 1 is fitted downwards onto the outer wall of the inner cover 3, so that the slider 12 is engaged into the spiral groove 32, so that the top cover 1 completely covers the information code 34.

[0022] First, it should be stated that the information code 34 is located on the outside of the inner cover 3, with the top cover 1 and locking sleeve 2 covering the outside of the information code 34. When the top cover 1 is rotated, causing the slider 12 to slide spirally upward in the spiral groove 32 and abut against the inner wall of the upper end of the spiral groove 32, the top cover 1 moves upward, exposing the upper part of the information code 34, but the lower part of the information code 34 is covered by the locking sleeve 2, avoiding the risk of the information code 34 being completely exposed and stolen; and when it is necessary to open the cover normally, the top cover 1 is rotated again, and the slider 12 acts on the aforementioned spiral groove 32. The inner wall of the upper end of the sliding groove 32, the top cover 1 drives the inner cover 3 to rotate synchronously, so that the inner cover 3 moves up from the second mounting part 52, so that the first protrusion 31 and the second protrusion 21 elastically disengage, and the lower part of the inner cover 3 completely disengages from the locking sleeve 2, so that the information code 34 can be fully displayed. At this time, the first protrusion 31 and the second protrusion 21 abut against each other, and the outer part of the inner cover 3 cannot be locked into the locking sleeve 2 again, so that the inner cover 3 cannot be restored. During the opening process, the side information code 34 of the inner cover 3 is gradually displayed in stages, which improves the anti-counterfeiting effect.

[0023] Furthermore, the lower end of the top cover 1 is provided with an annular elastic tightening part 13, and the outer wall of the inner cover 3 is provided with an arc-shaped protrusion 33. The information code 34 is provided on the outer wall of the arc-shaped protrusion 33. The elastic tightening part 13 and the arc-shaped protrusion 33 are interference-fitted. When the top cover 1 is rotated, the slider 12 slides to abut against the inner wall of the upper end of the spiral groove 32, and the elastic tightening part 13 is sleeved on the upper part of the arc-shaped protrusion 33. That is, during the normal opening process, rotating the top cover 1 causes the slider 12 to slide in the spiral groove 32, causing the top cover 1 to move upward relative to the inner cover 3, so that the part of the information code 34 not covered by the locking sleeve 2 is gradually exposed. When the top cover 1 is rotated, the slider 12 slides away from the spiral groove 32 and away from the locking sleeve 2. When the inner wall of one end of the tight sleeve 2 abuts, the elastic tightening part 13 is completely ejected from the outside of the arc-shaped protrusion 33, which positions the top cover 1 and prevents it from returning to its original position. When the top cover 1 continues to rotate, the slider 12 abuts against the spiral groove 32 away from the inner wall of one end of the locking sleeve 2, and the force is greater than the effect of the threaded engagement of the inner cover 3 and the second mounting part 52, causing the inner cover 3 to rotate relative to the second mounting part 52. At the same time, the inner cover 3 is displaced relative to the locking sleeve 2. When it is rotated to the preset position, the first protrusion 31 and the second protrusion 21 are elastically disengaged, so that the information code 34 is fully exposed. At this time, neither the top cover 1 nor the inner cover 3 can return to their original position normally. They are in a fully open state, which prevents criminals from stealing the information code 34 and restoring the structure to its original state, thus improving the anti-counterfeiting effect.

[0024] The inner wall of the inner cover 3 is provided with a first positioning block 37, and the outer wall of the bottom cover 5 is provided with a second positioning block 53 that engages with the positioning block 36, so as to ensure that the inner cover 3 can be installed in place during the installation process.

[0025] Furthermore, the top cover 1 is provided with a positioning groove 14, and the inner wall of the inner cover 3 is provided with a positioning protrusion 36 that slides with the positioning groove 14, so as to ensure stable assembly of the top cover 1 and the inner cover 3 and ensure stability.

[0026] To ensure that the top cover 1 can be stably assembled to the outside of the inner cover 3, a clearance groove 11 is vertically provided on the outer wall of the top cover 1. The clearance groove 11 is used to deform the top cover 1 outward by applying force to the inner wall of the top cover 1. An inclined surface 35 is provided on the upper edge of the top cover 1. The spiral groove 32 is located below the inclined surface 35. When a downward force is applied to the top cover 1, the top cover 1 deforms to the circumference. The slider 12 slides relative to the inclined surface 35 and continues to slide downward into the spiral groove 32. During assembly, the top cover 1 is placed above the top of the inner cover 3, and a force is applied to the top cover 1 so that the slider 12 abuts against the inclined surface 35 and slides relative to the inclined surface 35, causing the top cover 1 shell on both sides of the clearance groove 11 to undergo outward elastic deformation. When the slider 12 slides into the spiral groove 32, the top cover 1 shell returns to its original shape, completing the installation process of the top cover 1.

[0027] In summary, this utility model proposes a structure for a bottle cap with a hidden anti-theft information code, including a bottom cap 5 for connecting to the container outlet and a flow restrictor 4 fitted inside the bottom cap 5. The outer wall of the bottom cap 5 is provided with a first mounting part 51 and a second mounting part 52. A locking sleeve 2 is fitted onto the outer side of the first mounting part 51, and an inner cap 3 is threaded onto the outer side of the second mounting part 52. An information code 34 is provided on the outer wall of the inner cap 3. A first protruding edge 31 is provided on the outer end of the inner cap 3 near the first mounting part 51. A second protruding edge 21 is provided on the inner end of the locking sleeve 2 near the second mounting part 52. The end of the inner cap 3 with the first protruding edge 31 extends to the first mounting part 51. The upper end of the locking sleeve 2 is fitted onto the upper part of the inner cap 3. The position and fit are interference fit, and the first protruding edge 31 and the second protruding edge 21 abut against each other. The upper part of the locking sleeve covers the information code 34. The outer side of the inner cover 3 is fitted with a top cover 1, which completely covers the part of the information code 34 that is not covered by the locking sleeve 2. The inner wall of the top cover 1 is provided with a slider 12, and the outer wall of the inner cover 3 is provided with a spiral groove 32. When the top cover 1 is rotated so that the slider 12 slides to abut against the inner wall of the spiral groove 32 away from the locking sleeve 2, the part of the information code 34 that is not covered by the locking sleeve 2 is exposed. The information code 34 is innovatively set on the side of the inner cover 3. The locking cover and the lower sleeve together hide the information code 34, making the information code 34 difficult to steal and with high anti-counterfeiting properties. During the opening process, the side information code 34 on the inner cover 3 gradually appears in stages. Only when the cover is opened normally, the first mating part of the locking cover rotates above the limiting protrusion, the locking cover is locked and cannot be reset, and the side information code 34 is partially displayed. If the cover is opened further, the edge of the inner cover 3 pops out from the limiting edge, and the side information code 34 is fully displayed, allowing for scanning to verify authenticity. When criminals attempt to steal the information code 34 by pulling the locking cover upwards, usually the locking cover is pulled out, but the edge of the inner cover 3 is still at the lower limiting edge, and part of the side information code 34 remains hidden at the lower limiting edge, not fully displayed, and cannot be stolen, thus achieving the purpose of preventing the theft of the information code 34.
