Pull-off cap

Abstract

The present invention discloses a pull-out, break-off petal bottle cap, comprising an outer cap, a middle cap, an inner cap, and a lower sleeve, and further comprising an anti-counterfeiting fastener. The anti-counterfeiting fastener is used to limit the axial movement of the middle cap and the outer cap when pulled out. The anti-counterfeiting fastener breaks when pulled out, and the broken portion of the anti-counterfeiting fastener is located outside the outer cap. The middle cap and the outer cap can rotate relative to the anti-counterfeiting fastener when they are rotated. When the bottle cap of the present invention is pulled out, the snap-fit ​​buckle is broken, which can visually reflect that the bottle cap is pulled open, thereby playing a first anti-counterfeiting role. When the bottle cap is rotated open, the snap-fit ​​buckle is damaged by axial and radial forces, thereby playing a second anti-counterfeiting role. At the same time, when the bottle cap is rotated open, the middle cap and the outer cap move upward relative to the inner cap by a height H, thereby playing a third anti-counterfeiting role.

Description

Technical Field

[0001] The invention relates to the technical field of bottle cap anti-counterfeiting, in particular to a pull-out, break-off petal bottle cap. Background Art

[0002] Anti-counterfeiting bottle caps are widely used in alcoholic beverages, and there are various ways to make them. Currently, a commonly used anti-counterfeiting bottle cap includes an inner cap, a middle cap, an inner sleeve, a lower sleeve, an outer cap, and an inner plug. The inner plug is arranged inside the inner sleeve, the inner cap is sleeved on the upper part of the inner sleeve through a threaded connection, the lower sleeve is sleeved on the lower part of the inner sleeve, the middle cap is sleeved on the inner cap, and the outer cap is sleeved on the lower sleeve. The outer cap is connected to the middle cap and is located on the outside of the middle cap. A time-delayed locking mechanism is provided between the middle cap and the inner cap. When opening the bottle cap, the outer cap is rotated so that the middle cap moves upward a certain distance H relative to the inner cap under the action of the time-delayed locking mechanism, and the outer cap also moves upward a certain distance H relative to the lower sleeve. As a result, the outer cap, the middle cap, and the inner cap form an integral part that is opened by rotating from the inner sleeve along the thread. When the bottle cap is opened for the first time, the outer cap has moved upward a certain distance H relative to the lower sleeve and the middle cap has moved upward a certain distance H relative to the inner cap from the position before opening. At this time, if the bottle cap is put back into the inner sleeve, the inner cap can still be installed in place, while the outer cap and the middle cap cannot be installed in place. Since the outer cap and the middle cap cannot be reinstalled in place, an anti-counterfeiting effect is achieved, such as the patent with publication number CN211108827U.

[0003] However, the aforementioned anti-counterfeiting bottle cap has the following defects: if the outer cap is forcibly pulled out with external force, the outer cap and the middle cap will be subjected to force together, and finally the middle cap and the inner cap will be separated. After the middle cap and the inner cap are separated, the aforementioned anti-counterfeiting function of the bottle cap cannot be realized when the inner cap is unscrewed. As a result, unscrupulous vendors can replace the wine to counterfeit it and then install the bottle cap. Summary of the Invention

[0004] The object of the present invention is to overcome the shortcomings of the prior art and provide a pull-out broken-petal bottle cap. When the bottle cap is pulled, the snap buckle is destroyed, which can intuitively reflect that the bottle cap is pulled open, thereby playing a first anti-counterfeiting role; and when the bottle cap is rotated to open, the snap buckle is destroyed by axial and radial forces, thereby playing a second anti-counterfeiting role. At the same time, when the bottle cap is rotated to open, the middle cover and the outer cover are moved up to a height H relative to the inner cover, thereby playing a third anti-counterfeiting role.

[0005] The object of the present invention is achieved through the following technical solutions:

[0006] The pull-out cap and broken-flap bottle cap comprises an outer cap, a middle cap, an inner cap and a lower cover, and also comprises an anti-counterfeiting fastener, which is used to limit the axial movement of the middle cap and the outer cap when pulling. The anti-counterfeiting fastener breaks when pulling, and the broken part of the anti-counterfeiting fastener is located on the outside of the outer cap; and the middle cap and the outer cap can rotate relative to the anti-counterfeiting fastener when rotating.

[0015] Furthermore, at least one first anti-pullout platform is uniformly distributed on the outer wall of the inner cover along the circumferential direction, and a second anti-pullout platform corresponding to the first anti-pullout platform is provided on the inner wall of the middle cover.

[0016] The beneficial effects of the present invention are:

[0017] 1) When the bottle cap of the present invention is pulled, the snap buckle is destroyed, which can visually reflect that the bottle cap is pulled open, thereby playing a first anti-counterfeiting role; and when the bottle cap is rotated to open, the snap buckle is destroyed by axial and radial forces, thereby playing a second anti-counterfeiting role. At the same time, when the bottle cap is rotated to open, the middle cover and the outer cover rise by a height H relative to the inner cover, thereby playing a third anti-counterfeiting role.

[0018] 2) The bottle cap of the present invention has not only an anti-counterfeiting function in which the middle cover and outer cover are not raised but the snap buckle is broken, which visually indicates that the bottle cap has been pulled open, but also an anti-counterfeiting function in which the middle cover and outer cover are raised and the snap buckle is broken, which visually indicates that the bottle cap has been rotated open.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0029] See Figures 1-8 , the present invention provides a technical solution:

[0030] Example:

[0031] like Figures 1-8As shown, a pull-out broken-flap bottle cap comprises an outer cap 1, a middle cap 2, an inner cap 3 and a lower sleeve 4, and also comprises an anti-counterfeiting fastener 5. The anti-counterfeiting fastener 5 is used to limit the axial movement of the middle cap 2 and the outer cap 1 when pulling. The anti-counterfeiting fastener 5 breaks when pulling, and the broken part of the anti-counterfeiting fastener 5 is located outside the outer cap 1 (the broken part located outside the outer cap 1 means that the anti-counterfeiting fastener is partially exposed, and the surface of the convex part of the clamping part 12 described below is flush with the outer surface of the outer cap 1); and the middle cap 2 and the outer cap 1 can rotate relative to the anti-counterfeiting fastener 5 when they are rotated.

[0032] like Figure 4 and Figure 5 As shown, the anti-counterfeiting fastener 5 includes a snap-fit ​​buckle 6, which is connected to the lower sleeve 4. The inner wall of the snap-fit ​​buckle 6 is provided with a first snap-fit ​​groove 7 along the circumference, and the outer wall of the snap-fit ​​buckle 6 is provided with a second snap-fit ​​groove 8 along the circumference;

[0033] The middle cover 2 is provided with a first clamping platform 9 adapted to the first clamping groove 7 , and the outer cover 1 is provided with a second clamping platform 10 adapted to the second clamping groove 8 .

[0034] like Figure 5 As shown, the snap buckle 6 includes a connecting seat 11 and a snap portion 12 with an S-shaped cross-section. The connecting seat 11 is connected to the lower sleeve 4. The surface of the protruding portion of the snap portion 12 is located between the lower sleeve 4 and the outer cover 1, and the surface of the protruding portion of the snap portion 12 is flush with the outer surface of the outer cover 1.

[0035] like Figure 1 As shown, the cross section of the upper end of the clamping portion 12 is wedge-shaped, and the cross section of the second clamping platform 10 is inverted wedge-shaped.

[0036] like Figure 4 As shown, at least one tearing hole 13 is provided on the convex part of the clamping part 12. The tearing hole 13 is used to reduce the strength of the clamping part 12, thereby reducing the difficulty of breaking the clamping part 12 when the bottle cap is pulled open or rotated open.

[0037] like Figure 3 and Figure 4 As shown, the inner wall of the outer cover 1 is provided with a clearance groove 14 along the axial direction, the second clamping platform 10 is arranged on the groove wall of the clearance groove 14, and the concave part of the clamping part 12 is hidden in the clearance groove 14.

[0038] The recess 14 is provided with an anti-counterfeiting opening 15, through which the protruding portion of the clamping portion 12 extends. The anti-counterfeiting opening 15 is used to expose the clamping portion 12, and the state of the clamping buckle 6 can be directly reflected through the anti-counterfeiting opening 15 when the bottle cap is opened.

[0039] Working principle: When assembling the bottle cap: (1) Press the middle cap 2 onto the outside of the inner cap 3. When pressing, make the first clamping platform 9 and the anti-counterfeiting fastener 5 misaligned. After the middle cap 2 is pressed into place, rotate the middle cap 2 so that the first clamping platform 9 on the middle cap 2 enters the first clamping groove 7. (2) Then press the outer cap 1 onto the outside of the middle cap 2 to complete the assembly of the bottle cap. The assembly of other parts of the bottle cap, such as the inner cap 3 and the inner sleeve 20 and the lower sleeve 4, is the same as the existing technology and will not be described here. When pressing the outer cap 1, align the second clamping platform 10 on the outer cap 1 with the second clamping groove 8 and then apply pressure. Since the cross-section of the upper end of the clamping part 12 is wedge-shaped and the cross-section of the second clamping platform 10 is inverted wedge-shaped, the wedge-shaped structure plays a guiding role during the pressing process of the outer cap 1, which can ensure that the second clamping platform 10 is easily pressed into the second clamping groove 8.

[0040] During use: when the bottle cap is subjected to a pulling force, both the outer cover 1 and the middle cover 2 are subjected to the pulling force, and when the outer cover 1 and the middle cover 2 are pulled out, the anti-counterfeiting fastener 5 will be pulled off due to the action of the first clamping platform 9 and the second clamping platform 10, and then the anti-counterfeiting fastener 5 will be pulled off when the upper cover is pulled out. The anti-counterfeiting fastener 5 is destroyed and the anti-counterfeiting opening 15 of the anti-counterfeiting cover is exposed, thereby playing a direct anti-counterfeiting role in appearance.

[0041] During normal use of the bottle cap: The aforementioned clearance groove 14 is an arc-shaped structure, with a length of 1 / 10-1 / 3 of the circle it occupies. During normal rotation of the outer cap 1, the outer cap 1 drives the middle cap 2, causing the cap 2 to rise a distance H relative to the inner cap 3. However, when the middle cap 2 rotates until the side of the snap 6 contacts the sidewall of the clearance groove 14, the sidewall of the clearance groove 14 limits the snap 6, requiring the snap 6 to be broken before the middle cap 2 can continue to rotate. Therefore, when the middle cap 2 rotates until the guide teeth enter the guide groove, the snap 6 is broken, achieving the anti-counterfeiting effect of "opening the cap and destroying the petal."

[0042] In the process of breaking the snap buckle 6, it is not only subjected to the circumferential resistance of the side wall of the yield groove 14, but also subjected to the axial force of the first snap platform 9 and the second snap platform 10 on the snap buckle 6 due to the rising of the middle cover 2 and the outer cover 1, so that the snap buckle 6 can be easily broken when the bottle cap is opened.

[0043] When the bottle cap of the present invention is pulled, the snap buckle 6 is destroyed, which can intuitively reflect that the bottle cap is pulled open, thereby playing a first anti-counterfeiting role; and when the bottle cap is rotated to open, the snap buckle 6 is destroyed by axial and radial forces, thereby playing a second anti-counterfeiting role. At the same time, when the bottle cap is rotated to open, the middle cover 2 and the outer cover 1 rise to a height H relative to the inner cover 3, thereby playing a third anti-counterfeiting role.

[0044] The bottle cap of the present invention not only has an anti-counterfeiting function that can visually reflect that the bottle cap has been opened by pulling when the middle cover 2 and the outer cover 1 are not raised but the snap buckle 6 is broken, but also has an anti-counterfeiting function that can visually reflect that the bottle cap has been opened by rotating when the middle cover 2 and the outer cover 1 are raised and the snap buckle 6 is broken.

[0045] Further, if Figure 1 、 Figure 2 and Figure 5 As shown, a connecting notch is provided at the top of the lower sleeve 4, and the connecting seat 11 includes a connecting portion 16 with an arc-shaped cross-section and a connecting plate 17 with a rectangular cross-section. The connecting portion 16 is adapted to the connecting notch, and the connecting plate 17 is arranged in the lower sleeve 4 and fits against the inner wall of the lower sleeve 4.

[0046] The connecting portion 16 is used to cooperate with the lower sleeve 4 to provide support for the snap buckle 6, and is also used to make the outermost side of the snap buckle 6 flush with the outer surface of the outer cover 1. The connecting plate 17 is used to improve the connection strength between the snap buckle 6 and the lower sleeve 4.

[0047] Further, if Figure 6-Figure 8 As shown, the outer wall of the inner cover 3 is uniformly distributed along the circumference with at least one first anti-pullout platform 18. The inner wall of the middle cover 2 is provided with a second anti-pullout platform 19, which corresponds to the first anti-pullout platform 18 above and below it. The first anti-pullout platform 18 is located above the second anti-pullout platform 19, and the opposing sides of the two cross-sections are inclined. In this embodiment, there are two first anti-pullout platforms 18 and two second anti-pullout platforms 19.

[0048] The first anti-pullout platform and the second anti-pullout platform are used to improve the anti-pullout strength of the middle cover and the inner cover.

It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Rather, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the concept described herein through the above teachings or techniques or knowledge in the relevant field.
