Description

Technical Field

[0001] The utility model relates to the field of anti-counterfeiting bottle caps, in particular to an anti-counterfeiting bottle cap which is easy to assemble. Background Art

[0002] Bottle caps generally achieve anti-counterfeiting, anti-theft, and anti-adulteration features through structural destructibility and anti-counterfeiting features on the outer packaging. Current bottle caps are screwed onto the bottle mouth via a threaded connection. A breakable connection mates with a ring fixed to the bottle mouth to seal the bottle body. A gasket inside the cap seals the bottle mouth. To open the bottle cap, the cap is rotated to break the breakable connection between the cap and the ring, allowing it to open. The connection between the breakable connection points is typically welded together, requiring not only press-fit assembly but also spot welding, making the assembly process cumbersome. To address this issue, we designed an easy-to-assemble anti-counterfeiting bottle cap. Utility Model Content

[0003] In order to solve the technical problem that not only press-fit assembly but also spot welding is required during assembly, which makes the assembly process more complicated, the utility model provides an anti-counterfeiting bottle cap that is easy to assemble.

[0004] The utility model is realized by the following technical solutions: an anti-counterfeiting bottle cap that is easy to assemble, comprising a neck sleeve, a bottle mouth is sleeved inside the neck sleeve, an inner plug is sleeved inside the bottle mouth, an outer ring surface of the inner plug is sealed with the inner wall of the bottle mouth, the upper half of the bottle mouth is placed above the neck sleeve, and the upper half of the bottle mouth is screwed and connected with a white cover, an upper cover is provided above the neck sleeve, the white cover extends into the interior of the upper cover, a top cover is clamped above the upper cover, and a glass head is clamped above the top cover;

[0005] Among them, positioning protrusions are provided on the front and rear sides of the lower inner part of the lower end of the upper cover, and the positioning protrusions on both sides are symmetrically distributed, and two limiting plates are symmetrically distributed on the front and rear sides of the top of the neck sleeve, and a plurality of equally spaced connecting strips are integrally connected between the limiting plates and the top of the neck sleeve, and a gap is formed between two adjacent connecting strips, and the positioning protrusion is snapped into the gap.

[0006] As a further improvement of the above scheme, abutment plates are provided on the front and rear sides of the lower inner part of the lower end of the upper cover, and the two abutment plates are respectively opposite to the positioning protrusions on the front and rear sides, and the abutment plates are in contact with the surfaces of the limit plates and the connecting strips. When the upper cover is inserted from top to bottom onto the top of the neck sleeve, the abutment plates are on the inner side of the limit plates and in contact with them. The abutment plates will abut against the limit plates and the connecting strips to prevent them from being deformed or damaged, while the positioning protrusions will be deformed. When the upper cover is in full contact with the neck sleeve, the positioning protrusions are clamped in the gap formed by the connecting strips and the limit plates. At this time, the upper cover is installed with the neck sleeve, and the two can only be rotated but cannot be pulled up and down.

[0007] As a further improvement of the above solution, two positioning columns are further provided at the top of the neck sleeve, and two positioning holes matching the positioning columns are provided at the bottom of the upper cover. The positioning columns are interference-connected to the positioning holes to improve the connection strength between the two.

[0008] As a further improvement to the above solution, the upper end of the top cover is integrally formed with a connecting arc portion, and the outer surfaces of the glass head on both sides are designed with an arc-shaped structure, and the glass head is plugged into the connecting arc portion;

[0009] The bottom end of the glass head is also provided with a pressing head with a hexagonal structure, and the top end of the upper cover is provided with a pressing groove with a hexagonal structure. The pressing head and the pressing groove are interference connected. After the glass head is pressed and connected to the top cover, it is also connected to the upper cover for the second time, thereby improving the overall connection strength of the glass head.

[0010] As a further improvement of the above solution, the upper half of the upper cover is a regular hexagonal structure, and a plurality of evenly distributed connecting protrusions are provided on the side surface of the upper half of the upper cover. The inner wall of the top cover is provided with a plurality of connecting grooves matching the connecting protrusions. The connecting protrusions are snapped into the connecting grooves, and the top cover is pressed from top to bottom onto the upper half of the upper cover. During the process of contacting with the top of the upper cover and pressing downward, the inner wall of the top cover will deform to a certain extent. When the upper cover and the top cover are completely connected, the connecting protrusions will be snapped into the connecting grooves, thereby completing the connection between the two, and they cannot be disassembled again.

[0011] As a further improvement of the above solution, a plurality of evenly distributed connecting strips are provided on the lower half of the outer surface of the bottle mouth, and a plurality of evenly distributed mounting ribs are provided on the inner wall of the neck sleeve, and the plurality of connecting strips and the plurality of mounting ribs are staggered. When the bottle mouth plug is connected to the inside of the neck sleeve, the connecting strips can be snapped into the space formed by adjacent mounting ribs, thereby connecting the two, and the contact area is large, which also improves the connection strength.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model sets a limit plate and a connecting strip on the top of the neck sleeve, and sets a positioning protrusion in the upper cover. When the neck sleeve is connected to the upper cover, the positioning protrusion can be placed in the gap formed by the connecting strip and the limit plate. At this time, the upper cover is installed with the neck sleeve. The two can only be rotated but cannot be pulled up and down. The upper cover and the top cover are connected by the connecting groove and the connecting protrusion. The two can also be quickly connected. The entire anti-counterfeiting bottle cap adopts a press-fit connection, and multiple components can be quickly connected.

[0014] 2. After the neck sleeve is connected to the upper cover, it cannot be pulled up and down but can only be rotated, and the white cover is placed inside the upper cover. When using this bottle cap, the white wine can only be opened by twisting the upper cover. The rotation of the upper cover will cause the limit plate and the connecting strip to be damaged by the positioning protrusion, making it impossible to use it a second time, thereby achieving an anti-counterfeiting effect.

It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example:

[0026] Please combine Figure 1-Figure 7The present embodiment is an easy-to-assemble anti-counterfeit bottle cap, comprising a neck sleeve 4, a bottle mouth 6 is sleeved inside the neck sleeve 4, an inner plug 7 is sleeved inside the bottle mouth 6, the outer ring surface of the inner plug 7 is sealed with the inner wall of the bottle mouth 6, the upper half of the bottle mouth 6 is placed above the neck sleeve 4, and the upper half of the bottle mouth 6 is screwed and connected with a white cover 5, an upper cover 3 is provided above the neck sleeve 4, the white cover 5 extends into the interior of the upper cover 3, a top cover 2 is clamped above the upper cover 3, and a glass head 1 is clamped above the top cover 2;

[0027] Among them, positioning protrusions 34 are provided on the front and rear sides of the lower inner part of the lower end of the upper cover 3, and the positioning protrusions 34 on both sides are symmetrically distributed. Two limiting plates 41 are symmetrically distributed on the front and rear sides of the top of the neck sleeve 4. A plurality of equally spaced connecting strips 43 are integrally connected between the limiting plates 41 and the top of the neck sleeve 4, and a gap is formed between two adjacent connecting strips 43, and the positioning protrusion 34 is snapped into the gap.

[0028] The two abutment plates 33 are respectively opposite to the positioning protrusions 34 on the front and rear sides, and the abutment plates 33 are in surface contact with the limiting plates 41 and the connecting strips 43. When the upper cover 3 is inserted from top to bottom onto the top of the neck sleeve 4, the abutment plates 33 are on the inner side of the limiting plates 41 and in contact with them. The abutment plates 33 will abut against the limiting plates 41 and the connecting strips 43 to prevent them from being deformed or damaged, while the positioning protrusions 34 will be deformed. When the upper cover 3 is in full contact with the neck sleeve 4, the positioning protrusions 34 are clamped in the gap formed by the connecting strips 43 and the limiting plates 41. At this time, the upper cover 3 is completely installed with the neck sleeve 4, and the two can only be rotated but cannot be pulled up and down.

[0029] Two positioning posts 42 are further provided at the top of the neck sleeve 4, and two positioning holes matching the positioning posts 42 are provided at the bottom of the upper cover 3. The positioning posts 42 are interference-connected into the positioning holes to improve the connection strength between the two.

[0030] The upper end of the top cover 2 is integrally formed with a connecting arc portion 21. The outer surfaces of the glass head 1 on both sides are designed with an arc-shaped structure. The glass head 1 is plugged into the connecting arc portion 21.

[0031] The bottom end of the glass head 1 is also provided with a hexagonal pressing head 11, and the top of the upper cover 3 is provided with a hexagonal pressing groove. The pressing head 11 and the pressing groove are interference connected. After being pressed and connected with the top cover 2, the glass head 1 is also connected to the upper cover 3 for the second time, thereby improving the overall connection strength of the glass head 1.

[0032] The upper part of the upper cover 3 is a regular hexagonal structure. The side of the upper part of the upper cover 3 is provided with a plurality of evenly distributed connecting protrusions 31. The inner wall of the top cover 2 is provided with a plurality of connecting grooves 22 matching the connecting protrusions 31. The connecting protrusions 31 are snapped into the connecting grooves 22. The top cover 2 is pressed from top to bottom to the upper half of the upper cover 3. During the process of contacting with the top of the upper cover 3 and pressing downward, the inner wall of the top cover 2 will deform to a certain extent. When the upper cover 3 and the top cover 2 are fully connected, the connecting protrusions 31 will be snapped into the connecting grooves 22, thereby completing the connection between the two and cannot be disassembled again.

[0033] A plurality of evenly distributed connecting strips 61 are provided on the lower half of the outer surface of the bottle mouth 6, and a plurality of evenly distributed mounting ribs are provided on the inner wall of the neck sleeve 4, and the plurality of connecting strips 61 and the plurality of mounting ribs are staggered. When the bottle mouth 6 is plugged into the interior of the neck sleeve 4, the connecting strips 61 can be snapped into the space formed by the adjacent mounting ribs, thereby connecting the two, and the contact area is large, which also improves the connection strength.

[0034] The implementation principle of an easy-to-assemble anti-counterfeit bottle cap in the embodiment of the present application is as follows: when assembling the anti-counterfeit bottle cap, first, the inner plug 7 is plugged into the inside of the bottle mouth 6. At this time, there is a certain space between the outer wall of the inner plug 7 and the inner wall of the bottle mouth 6, which can be used to fix on the bottle mouth of the wine bottle, and the inner plug 7 is placed inside the bottle mouth. The white cover 5 is screwed on the bottle mouth 6, and then the neck sleeve 4 is pressed onto the bottle mouth 6 from top to bottom. When the bottle mouth 6 is plugged into the inside of the neck sleeve 4, the connecting ribs can be snapped into the space formed by the adjacent mounting ribs, so that the two are connected, and the contact area is large, which also improves the connection strength;

[0035] When the neck sleeve 4 is connected to the upper cover 3, the upper cover 3 is directly pressed from top to bottom onto the neck sleeve 4. The positioning column 42 is interference-connected to the positioning hole, and the abutment plate 33 is on the inner side of the limiting plate 41 and contacts it. The positioning protrusion 34 will be deformed. When the upper cover 3 is completely in contact with the neck sleeve 4, the positioning protrusion 34 is clamped in the gap formed by the connecting strip 43 and the limiting plate 41. At this time, the upper cover 3 is completely installed with the neck sleeve 4. The two can only be rotated but cannot be pulled up and down. The glass head 1 is pressed onto the connecting arc 21, and then the top cover 2 is connected to the connecting protrusion 31 of the upper cover 3 through the connecting groove 22, thereby completing the assembly of the entire anti-counterfeiting bottle cap.

[0036] By providing a limiting plate 41 and a connecting strip 43 on the top of the neck sleeve 4, and providing a positioning protrusion 34 in the upper cover 3, when the neck sleeve 4 is connected to the upper cover 3, the positioning protrusion 34 can be placed in the gap formed by the connecting strip 43 and the limiting plate 41. At this time, the upper cover 3 is completely installed with the neck sleeve 4, and the two can only be rotated but cannot be pulled up and down. The upper cover 3 is connected to the top cover 2 through the connecting groove 22 and the connecting protrusion 31, and the two can also be quickly connected. The entire anti-counterfeiting bottle cap adopts a press-fit connection, and multiple components can be quickly connected;

[0037] After the neck sleeve 4 is connected to the upper cover 3, it cannot be pulled up and down but can only be rotated, and the white cover 5 is placed inside the upper cover 3. When opening the bottle of white wine using this bottle cover, the upper cover 3 must be twisted to open it. The rotation of the upper cover 3 will cause the limiting plate 41 and the connecting strip 43 to be damaged by the positioning protrusion 34, making it impossible to use it a second time, thereby achieving an anti-counterfeiting effect.

[0038] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
