Inner sleeve body, anti-fake bottle cap and wine bottle

Abstract

The application relates to an inner sleeve body, a forgery-proof bottle cap and a wine bottle. The inner sleeve body has an axially-through inner sleeve cavity. A through window is arranged on the side wall of the inner sleeve body and is communicated with the inner sleeve cavity. A clamping element is arranged in the through window. The top end of the clamping element is connected with the top end of the through window. The bottom end of the clamping element is provided with a clamping end head. The clamping element has a deformation capacity and can be deformed radially inward under the action of external force, so that the clamping end head moves radially inward and is used for locking the bottle mouth. After the outer sleeve body is firmly sleeved on the outside of the inner sleeve body through pressing, the external force applied by the outer sleeve body to the clamping end head of the clamping element in the inner sleeve body can be kept constant. After the clamping end head is accommodated in the annular locking recess of the bottle mouth under the action of the force and the deformation of the clamping element, as long as the pressing of the outer sleeve body does not loosen, the clamping end head can be locked in the bottle mouth very firmly, so that the forgery-proof bottle cap cannot be easily pulled out from the bottle cap.

[0009] In one embodiment, the maximum height of the first protrusion protruding from the outer sidewall of the snap-fit ​​element is a first height, and the maximum height of the second protrusion protruding from the inner sidewall of the snap-fit ​​element is a second height, wherein the first height is greater than the second height.

[0010] In one embodiment, the snap-fit ​​element and the inner sleeve body are integrally formed; and / or,

[0011] The snap-fit ​​element has a sheet-like structure. The first protrusion is a first linear protrusion arranged laterally along the outer sidewall of the bottom end of the snap-fit ​​element, and the second protrusion is a second linear protrusion arranged laterally along the inner sidewall of the bottom end of the snap-fit ​​element.

[0012] In one embodiment, the inner sleeve body includes a top inner sleeve section and a bottom inner sleeve section connected along the axial direction. The diameter of the top inner sleeve section is smaller than the diameter of the bottom inner sleeve section. The top inner sleeve section and the bottom inner sleeve section are connected by a transition platform. The top inner sleeve section has a threaded structure. The through window and the snap-fit ​​element are both located in the bottom inner sleeve section.

[0013] This application provides an anti-counterfeiting bottle cap, the anti-counterfeiting bottle cap comprising:

[0014] An inner plug element for inserting into the interior of the bottle opening;

[0015] The inner sleeve body is assembled outside the inner plug element, and a receiving gap cavity for receiving the bottle mouth is formed between the inner sidewall of the inner sleeve body and the outer sidewall of the inner plug element.

[0016] An outer sleeve body is assembled outside the inner sleeve body and is used to apply an external force to the inner sleeve body that causes the locking element to deform radially inward, so that the locking end moves radially inward to lock the bottle mouth.

[0017] In one embodiment, the inner plug element includes, along the axial direction, a connected assembly element segment and an inner plug element segment, the inner sleeve body is assembled outside the assembly element segment, the inner plug element segment is used to insert into the interior of the bottle neck, and a limiting plate is provided between the assembly element segment and the inner plug element segment, the limiting plate being used to limit and engage with the end of the bottle neck.

[0018] In one embodiment, the inner wall of the outer sleeve has a receiving area and a force-applying area. The wall thickness of the receiving area in the outer sleeve is less than the wall thickness of the force-applying area.

[0023] In the aforementioned inner sleeve, anti-counterfeiting bottle cap, and wine bottle, the inner sleeve is provided with a deformable snap-fit ​​element. The deformable snap-fit ​​element can cause the snap-fit ​​end to move radially inward when subjected to external force. This structure of the inner sleeve can cooperate with the outer sleeve. Since the outer sleeve is assembled on the outside of the inner sleeve after being pressed and securely fitted to the outside of the inner sleeve, the external force applied by the outer sleeve to the snap-fit ​​end of the snap-fit ​​element in the inner sleeve can remain constant. After the snap-fit ​​element deforms under force, the snap-fit ​​end is accommodated in the annular locking recess of the bottle mouth. As long as the pressing of the outer sleeve does not loosen and the external force is continuously applied to the snap-fit ​​end, the snap-fit ​​end can be securely locked in the bottle mouth, so that the anti-counterfeiting bottle cap cannot be easily pulled out of the bottle cap.

[0041] See Figures 1 to 4 As shown, this application provides an anti-counterfeiting bottle cap, which is used to install on the bottle mouth 100 of a wine bottle. A ring-shaped locking recess 100a can be provided on the bottle mouth 100 to form a space that can fix and snap the anti-counterfeiting bottle cap, so that the anti-counterfeiting bottle cap can be securely snapped on the bottle mouth 100. The anti-counterfeiting bottle cap includes an inner plug element 2000, an inner sleeve body 1000, and an outer sleeve body 3000. The inner plug element 2000 is inserted into the inside of the bottle mouth 100. The inner sleeve body 1000 is assembled on the outside of the inner plug element 2000, and a receiving gap cavity for accommodating the bottle mouth 100 is formed between the inner side wall of the inner sleeve body 1000 and the outer side wall of the inner plug element 2000. Therefore, when the anti-counterfeiting bottle cap is assembled on the bottle mouth 100, a part of the structure of the inner plug element 2000 is located inside the bottle mouth 100, and another part of the structure is assembled with the inner sleeve body 1000. At the same time, the inner sleeve body 1000 is located outside the bottle mouth 100, and the receiving gap cavity formed between the inner side wall of the inner sleeve body 1000 and the outer side wall of the inner plug element 2000 accommodates the bottle mouth 100.

[0042] An embodiment of this application provides an inner sleeve 1000 for use in anti-counterfeiting bottle caps. The inner sleeve 1000 includes an inner sleeve body and a snap-fit ​​element 1200. The inner sleeve body has an axially penetrating inner sleeve cavity. A penetrating window 1100 is opened on the side wall of the inner sleeve body, which connects to the inner sleeve cavity. The snap-fit ​​element 1200 is disposed in the penetrating window 1100. The top end of the snap-fit ​​element 1200 is connected to the top end of the penetrating window 1100. The bottom end of the snap-fit ​​element 1200 is provided with a snap-fit ​​end 1210. The snap-fit ​​element 1200 has deformation capability and can deform radially inward under the action of external force, so that the snap-fit ​​end 1210 moves radially inward to lock the bottle mouth 100. The outer sleeve 3000 is assembled outside the inner sleeve 1000 and is used to apply an external force to the inner sleeve 1000 that causes the snap-fit ​​element 1200 to deform radially inward, so that the snap-fit ​​end 1210 moves radially inward to lock the bottle mouth 100.

[0043] The bottle neck 100 has a ring-shaped locking recess 100a, which allows the anti-counterfeiting cap to be snapped and fixed onto the bottle neck 100. The snap-fit ​​element 1200 on the inner sleeve 1000 is used to snap onto the ring-shaped locking recess 100a on the bottle neck 100, thus locking the entire anti-counterfeiting cap onto the bottle neck 100. The snap-fit ​​element 1200 can be made of various materials, as long as it has a certain deformation capacity. When subjected to external force applied by the outer sleeve 3000, it deforms, causing the snap-fit ​​end 1210 to move radially inward, allowing it to enter the ring-shaped locking recess 100a of the bottle neck 100. The outer sleeve 3000 then presses and holds it within the ring-shaped locking recess 100a, thus locking the bottle neck 100. The snap-fit ​​element 1200 can be made of injection-molded material, such as conventional thermoplastics.

[0044] See Figure 3 and Figure 4As shown, it should be noted that the outer sleeve 3000 has a press-fit state and a non-press-fit state. The press-fit state of the outer sleeve 3000 means that the outer sleeve 3000 has been assembled outside the inner sleeve 1000 and an external force has been applied to the inner sleeve 1000. For example, the inner plug element 2000 is assembled inside the bottle mouth 100, the inner sleeve 1000 is assembled outside the inner plug element 2000 and the bottle mouth 100, and the outer sleeve 3000 is assembled outside the inner sleeve 1000. At this time, the outer sleeve 3000 has been press-fitted and applies the deformation effect of its press-fitted shape to the outside of the inner sleeve 1000, thus applying an external force to the inner sleeve 1000. The non-press-fit state of the outer sleeve 3000 means that the outer sleeve 3000 is not assembled outside the inner sleeve 1000 and no external force is applied to the inner sleeve 1000. For example, the inner plug element 2000 is assembled inside the bottle mouth 100, and the inner sleeve 1000 is assembled outside the inner plug element 2000 and the bottle mouth 100, but the outer sleeve 3000 is not yet assembled outside the inner sleeve 1000. Or the outer sleeve 3000 is assembled outside the inner sleeve 1000, but has not yet been press-fitted, and therefore no external force is applied to the inner sleeve 1000. In this case, the inner sleeve 1000 is not subjected to external force.

[0045] Since the outer sleeve 3000 is press-fitted onto the outside of the inner sleeve 1000, the external force applied by the outer sleeve 3000 to the snap-fit ​​end 1210 of the snap-fit ​​element 1200 in the inner sleeve 1000 can remain constant. After the snap-fit ​​element 1200 deforms under the force, the snap-fit ​​end 1210 is accommodated in the annular locking recess 100a of the bottle mouth 100. As long as the press-fitting of the outer sleeve 3000 does not loosen and the external force is continuously applied to the snap-fit ​​end 1210, the snap-fit ​​end 1210 can be securely locked in the bottle mouth 100, so that the anti-counterfeiting bottle cap cannot be easily pulled out of the bottle cap.

[0046] The snap-fit ​​end 1210 can adopt various structures. For example, the snap-fit ​​end 1210 of the snap-fit ​​element 1200 can be designed to be thick enough or large enough. After the snap-fit ​​element 1200 is subjected to the pressing force of the outer sleeve 3000, the snap-fit ​​element 1200 deforms inward in the neck direction, so that the snap-fit ​​end 1210 is accommodated in the annular locking recess 100a to form a snap, and is held in the annular locking recess 100a under the holding action of the outer sleeve 3000, thereby locking the bottle mouth 100. In one embodiment, the snap-fit ​​end 1210 includes a first protrusion 1210a located on the outer side wall of the bottom end of the snap-fit ​​element 1200. When the outer sleeve 3000 is fitted onto the outside of the inner sleeve 1000, the outer sleeve 3000 will contact the first protrusion 1210a, thereby applying an external force to the snap-fit ​​end 1210 on the snap-fit ​​element 1200 by means of the first protrusion 1210a. Therefore, the first protrusion 1210a is used to receive the external force, causing the snap-fit ​​element 1200 to deform radially inward. The snap-fit ​​end 1210 includes a second protrusion 1210b, which is located on the inner sidewall of the bottom end of the snap-fit ​​element 1200. When the snap-fit ​​element 1200 is deformed radially inward by an external force, the snap-fit ​​end 1210 is accommodated in the annular locking recess 100a to form a snap, and is held in the annular locking recess 100a by the holding action of the outer sleeve 3000, thereby locking the bottle mouth 100.

[0047] In one embodiment, the first protrusion 1210a protrudes beyond the outer wall of the locking element 1200 to a maximum height of a first height, and the second protrusion 1210b protrudes beyond the inner wall of the locking element 1200 to a maximum height of a second height, with the first height being greater than the second height. This causes the first protrusion 1210a to protrude further beyond the outer wall of the locking element 1200, thus allowing the outer sleeve 3000 to apply a greater external force to the inner sleeve 1000 when the outer sleeve 3000 is fitted over the inner sleeve 1000. This results in a greater radial inward deformation of the locking element 1200, thereby allowing the second protrusion 1210b to be more securely accommodated within the annular locking recess 100a of the bottle neck 100, more securely locking the bottle neck 100 and preventing the anti-counterfeiting cap from being easily pulled out.

[0048] In one embodiment, the snap-fit ​​element 1200 and the inner sleeve body are integrally formed. The snap-fit ​​element 1200 is a sheet-like structure. The first protrusion 1210a is a first linear protrusion arranged laterally along the outer sidewall of the bottom end of the snap-fit ​​element 1200. Therefore, the first protrusion 1210a can linearly receive external force in the circumferential direction of the outer sleeve body 3000. The second protrusion 1210b is a second linear protrusion arranged laterally along the inner sidewall of the bottom end of the snap-fit ​​element 1200. Therefore, the second protrusion 1210b can linearly accommodate in the annular locking recess 100a in the circumferential direction of the bottle mouth 100, thereby improving the locking ability.

[0049] In one embodiment, the inner sleeve body includes, along the axial direction, connected top inner sleeve section 1000a and bottom inner sleeve section 1000b. The diameter of the top inner sleeve section 1000a is smaller than the diameter of the bottom inner sleeve section 1000b. The top inner sleeve section 1000a and the bottom inner sleeve section 1000b are connected by a transition platform 1000c, which can bridge the diameter difference between the top inner sleeve section 1000a and the bottom inner sleeve section 1000b. The top inner sleeve section 1000a has a threaded structure 1000d, such as an external thread on the outside of the top inner sleeve section, so that the top inner sleeve section 1000a can be used to thread-install an outer cap. The through window 1100 and the snap-fit ​​element 1200 are both located in the bottom inner sleeve section 1000b. The bottom inner sleeve section 1000b is used to fit the bottle neck 100 and locks the bottle neck 100 using the snap-fit ​​element 1200.

[0050] In one embodiment, the inner plug element 2000 includes, along the axial direction, connected assembly element segment 2000a and inner plug element segment 2000b. The inner sleeve body 1000 is assembled outside the assembly element segment 2000a. The inner plug element segment 2000b is inserted into the bottle neck 100. A limiting latch 2000c is provided between the assembly element segment 2000a and the inner plug element segment 2000b, and the limiting latch 2000c is used for limiting engagement with the end of the bottle neck 100. The top inner sleeve segment 1000a and the assembly element segment 2000a are diametrically matched, and the bottom inner sleeve segment 1000b and the inner plug element segment 2000b are also diametrically matched. The top inner sleeve segment 1000a and the bottom inner sleeve segment 1000b are connected via a transition platform 1000c, so that the transition platform 1000c also engages with the limiting latch 2000c.

[0051] In one embodiment, the inner wall of the outer sleeve 3000 has a receiving region 3000a and a force-applying region 3000b. The receiving region 3000a is located below the force-applying region 3000b, and the receiving region 3000a and the force-applying region 3000b are connected. The wall thickness of the receiving region 3000a in the outer sleeve 3000 is less than the wall thickness of the force-applying region 3000b. The receiving region 3000a is used to receive the snap-fit ​​end 1210 of the snap-fit ​​element 1200, and the force-applying region 3000b is used to apply external force to the snap-fit ​​end 1210. For example, the receiving region 3000a is a recessed region formed on the inner wall of the outer sleeve 3000. Because this recessed region is lower than the inner wall of the outer sleeve 3000, therefore... It can be used to accommodate the snap-fit ​​end 1210. During the process of the outer sleeve 3000 being fitted into the inner sleeve 1000, the snap-fit ​​end 1210 of the snap-fit ​​element 1200 on the inner sleeve 1000 can first be accommodated in the accommodating area 3000a, such as in the recessed area. When the outer sleeve 3000 continues to press down, the snap-fit ​​end 1210 will move from the accommodating area 3000a to contact the force application area 3000b. Because the wall thickness of the accommodating area 3000a is less than the wall thickness of the force application area 3000b, when the force application area 3000b contacts the snap-fit ​​end 1210, it will apply an external force to the snap-fit ​​end 1210, causing the snap-fit ​​element 1200 to deform and push the snap-fit ​​end 1210 to lock the bottle mouth 100.

[0052] In one embodiment, at least one of the inner sleeve 1000 and the outer sleeve 3000 is provided with a positioning mechanism 3000c, and the inner sleeve 1000 and the outer sleeve 3000 are positioned and assembled by the positioning mechanism 3000c. For example, the positioning mechanism 3000c includes a protrusion and a groove. If the inner sleeve 1000 is provided with a groove, then the outer sleeve 3000 is provided with a protrusion; if the outer sleeve 3000 is provided with a groove, then the inner sleeve 1000 is provided with a protrusion. Those skilled in the art can configure it according to their needs, and no limitation is made here.

[0053] This application provides a wine bottle, comprising a bottle body and an anti-counterfeiting cap. The bottle body has a bottle mouth 100, which has an annular locking recess 100a. The anti-counterfeiting cap is fitted onto the bottle mouth 100, wherein the inner sleeve 1000 of the anti-counterfeiting cap is used to lock the bottle mouth 100. Since the specific structure, functional principle, and technical effects of the anti-counterfeiting cap and the inner sleeve 1000 have been described in detail above, they will not be repeated here. Any technical content regarding the anti-counterfeiting cap and the inner sleeve 1000 can be found in the preceding description.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application.
