Description

Technical Field

[0001] The utility model relates to the technical field of bottles, in particular to a pry-proof bottle cap, a bottle body and a bottle. Background Art

[0002] my country is one of the earliest countries to make wine. As early as 2000 years ago, there was winemaking technology. Through continuous improvement and perfection, my country's winemaking technology has now developed to produce wines of various concentrations and flavors. Since the prices of wines of different concentrations and flavors are very different, some people will seek profits by recycling old wine bottles and filling them with some industrial alcohol to counterfeit real wine. The bottle cap, as the seal of the bottle, is an important part of the liquid container packaging. At present, the price of a bottle of ordinary liquor (such as Kouzijiao, the specific model is 41 degrees, 500mL Xiaochijiao) on the market is generally between 160 yuan and 180 yuan. If someone recycles the old wine bottle through the above method and fills it with other wine, and it is assumed that an old wine bottle obtained through the above operation and filled with other wine can obtain a profit of about 100 yuan, according to this calculation, the profit will be very large, almost a ten thousand profit. Because the profit is very large, some people who pursue interests will take risks to obtain huge profits through the above means. Therefore, a pry-proof bottle is needed to avoid such incidents. A general pry-proof bottle includes a bottle body and a bottle cap, wherein the bottle body includes a bottleneck, and the outer side of the bottleneck is provided with a convex ring that is sleeved on the bottleneck; the bottle cap is installed on the bottleneck and is used to open or close the bottle mouth on the bottleneck. The bottle cap includes a metal pry-proof ring, which includes a ring body and at least one buckle arranged on the ring body for buckling on the convex ring to achieve the pry-proof of the bottle body.

[0003] In the prior art, although a certain structure is used between the bottle cap and the bottle body to prevent the bottle cap from detaching along the axial direction of the bottle, if a person continues to heat the bottle cap sideways with a hot air gun, it is easy to detach the main body of the bottle cap from the anti-pry ring without damaging the bottle mouth. In addition, there is a gap between the anti-pry ring and the bottle mouth in the prior art, and the anti-pry ring also extends out of the bottle mouth for a distance. When the anti-pry ring is installed on the bottle mouth, the anti-pry ring can be pulled up and down in the axial direction of the bottle mouth (as shown in the attached manual). Figure 1 As shown in (11)-(12) in the figure, there is a force point between the anti-pry ring and the bottle mouth. The anti-pry ring can be quickly removed from the bottle body by clamping the force point with tools such as steel pliers to complete the disassembly. The entire disassembly process will not damage the bottle mouth. The specific disassembly process is as shown in the attached manual. Figure 1 As shown, after the disassembly, some inferior wine or even industrial alcohol can be secretly mixed into the bottle, and then the counterfeit bottle cap can be used on the bottle after the secret mixing, and it can be sold at a higher price, thereby achieving the purpose of obtaining high profits. At the same time, inferior wine can also cause harm to the human body. Therefore, a pry-proof bottle is needed to solve the above technical problems. Utility Model Content

[0004] In order to solve the technical problem in the prior art that the anti-pry ring is easily removed from the bottleneck, which leads to some people seeking huge profits by recycling old bottles and filling inferior wine into the bottles, the utility model provides an anti-pry bottle cap, a bottle body and a bottle.

[0005] To achieve the above objectives, the technical solution adopted by the utility model is as follows: a bottle, comprising a bottle body and a bottle cap, the bottle body comprising a bottleneck, the outer side of the bottleneck being provided with a convex ring 1 which is sleeved on the bottleneck; the bottle cap is installed on the bottleneck and is used to open or close the bottle mouth on the bottleneck, the bottle cap comprising a metal anti-pry ring, the anti-pry ring comprising a ring body 1 and at least one buckle arranged on the ring body 1 and used to buckle against the convex ring 1 to achieve anti-pry of the bottle body; the end face of the bottleneck extends outward from the convex ring 1 to form an extension ring with an outer diameter smaller than the outer diameter of the convex ring 1; the anti-pry ring also comprises a ring body 2 and a reducing ring connecting the ring body 2 and the ring body 1, the outer diameter of the ring body 2 is smaller than the outer diameter of the ring body 1, and the outer diameter of the reducing ring changes from the outer diameter of the ring body 1 to the outer diameter of the ring body 1; the ring body 2 is fitted on the outer side of the extension ring and the outermost edge of the ring body 2 is flush with the end face of the extension ring.

[0006] As a further improvement of the above solution, an angle α is set between the second ring body and the central axis of the anti-pry ring, and the range of the angle α is 15°≥α≥0°.

[0007] As a further improvement of the above scheme, the anti-pry ring also includes a ring body three, which is formed by extending and expanding outward along one end of the ring body one away from the ring body two. The ring body three is a variable diameter structure, and the minimum outer diameter of the ring body three is the same as the outer diameter of the ring body one.

[0008] As a further improvement of the above solution, the buckle is an elastic buckle.

[0009] As a further improvement of the above solution, the length of the extension ring is 2mm-3mm.

[0010] As a further improvement of the above scheme, the bottleneck includes a bottleneck body and a convex ring 2, wherein the convex ring 2 is sleeved on the outside of the bottleneck body and the convex ring 2 is arranged on the side away from the extension ring; the diameter of the bottleneck body is the same as the diameter of the extension ring; the convex ring 2, the bottleneck body and the convex ring 1 are able to form a limiting groove, and the limiting groove is suitable for limiting the buckle.

[0011] As a further improvement of the above solution, the cross-section of the convex ring 1 is a trapezoidal structure, and the upper bottom surface of the trapezoid is arranged on a side close to the extension ring.

[0012] A bottle body is the bottle body included in the bottle.

[0013] A tamper-proof bottle cap is a bottle cap included in the bottle.

[0014] As a further improvement of the above scheme, the tamper-proof bottle cap also includes an outer cover assembly, a steel buckle and an inner plug. The steel buckle is arranged on the outside of the tamper-proof ring, and the steel buckle is integrally connected with the tamper-proof ring through injection molding. The inner plug is arranged inside the steel buckle, and one end of the inner plug is inserted into the bottleneck body. The outer cover assembly includes outer cover one and outer cover two. The outer cover one is installed on the upper end of the steel buckle, and the outer cover two is sleeved on the lower end of the steel buckle, and the contact surfaces of the outer cover one and the outer cover two fit each other.

[0015] As a further improvement of the above solution, the outer cover 1 and the steel buckle are threadedly connected.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) The utility model provides an extension ring, and the end of the extension ring away from the bottleneck is flush with the end of the ring body 2 away from the anti-pry ring, which can effectively solve the problem in the prior art that a gap is provided between the steel ring and the bottle mouth, which allows the anti-pry ring to be removed from the bottle mouth by tools such as steel pliers, so as to exchange inferior wine and replace the counterfeit wine bottle cap. Specifically, the utility model sets the extension ring and the ring body 2 on the anti-pry ring to be flush, and the ring body 2 is attached to the outside of the extension ring, so that there is no fulcrum between the anti-pry ring and the extension ring. Therefore, the anti-pry ring cannot be removed from between the ring body 2 and the extension ring by tools such as steel pliers. If the anti-pry ring is forcibly removed, the extension ring will break, making it impossible to seal between the bottle mouth and the bottle cap, so that even if a new bottle cap is installed, wine will leak. Therefore, the utility model can quickly determine whether the wine in the bottle has been replaced by whether the wine is leaking, which can effectively prevent some people from making huge profits by filling inferior wine into old wine bottles through such means.

[0018] (2) The utility model provides a ring body 2 and a reducing ring, and the reducing ring can connect the ring body 2 and the ring body 1, so that the diameter of the ring body 2 is much smaller than the diameter of the ring body 1. In this way, the anti-pry ring can be punched into the bottleneck through the ring body 1, and the anti-pry function can be achieved by the ring body 2 being attached to the outer side of the extension ring.

[0019] (3) The utility model provides a ring body three, and the ring body three is expanded outward along the lower end of the ring body one, so that the minimum inner diameter of the ring body three is also greater than or equal to the outer diameter of the bottleneck, so that the anti-pry ring can be inserted into the bottleneck smoothly by stamping, thereby improving the stability of the assembly between the anti-pry ring and the bottleneck.

[0020] (4) In the utility model, an angle α is set between the ring body 2 and the central axis of the anti-pry ring, and the maximum angle α cannot exceed 15°, which can effectively ensure the fit between the ring body 2 and the extension ring, and can also prevent the anti-pry ring from being removed by inserting tools such as steel pliers from the angle between the ring body 2 and the anti-pry ring. In this application, by limiting the range of the angle, it can not only weaken the assembly accuracy requirements between the anti-pry ring and the bottleneck, but also ensure that the anti-pry ring cannot be removed from the angle by tools such as steel pliers, thereby preventing people from seeking huge profits by removing the bottle cap and replacing inferior wine.

[0038] Example 1

[0039] Reference Figure 1-4As shown, a bottle provided in this embodiment includes a bottle body and a bottle cap, wherein the bottle body includes a bottleneck, and the outer side of the bottleneck is provided with a convex ring 24 sleeved on the bottleneck; the bottle cap is installed on the bottleneck and used to open or close the bottle mouth on the bottleneck, and the bottle cap includes a metal anti-pry ring 11, and the anti-pry ring 11 includes a ring body 112 and at least one buckle 116 arranged on the ring body 112 and buckled on the convex ring 24 to realize the anti-pry function of the bottle body. By providing at least one buckle 116, the anti-pry ring 11 can be effectively stuck on the bottleneck, thereby realizing the anti-pry function. The end face of the bottleneck extends outward from the convex ring 24 to form an extension ring 21 whose outer diameter is smaller than that of the convex ring 24; the anti-pry ring 11 also includes a ring body 111 and a reducing ring connecting the ring body 111 and the ring body 1 112, the outer diameter of the ring body 111 is smaller than that of the ring body 112, and the outer diameter of the reducing ring 113 changes from the outer diameter of the ring body 112 to the outer diameter of the ring body 112; the ring body 111 is fitted on the outer side of the extension ring 21 and the outermost edge of the ring body 111 is flush with the end face of the extension ring 21. The utility model provides a second ring body 111 and a reducing ring 113. The reducing ring 113 can connect the second ring body 111 and the first ring body 112, so that the diameter of the second ring body 111 is much smaller than the diameter of the first ring body 112. In this way, the anti-pry ring 11 can be punched to the bottleneck through the first ring body 112, and the anti-pry function can be achieved by the second ring body 111 being attached to the outer side of the extension ring 21.

[0040] The buckle 116 is an elastic buckle 116 .

[0041] like Figure 5-6 As shown, in this embodiment, one end of the reducer ring 113 is connected to the ring body 112, and the other end of the reducer ring 113 is connected to the ring body 2 111. The reducer ring 113 is formed by bending from the surface of the ring body 112 toward the central axis of the ring body 112. The anti-pry ring 11 is formed into an annular structure with an opening that gradually shrinks through the bending of the reducer ring 113. A corner 115 is provided at the connection between the ring body 2 111 and the reducer ring 113, and the bending direction of the corner 115 is opposite to the bending direction of the reducer ring 113. By providing the reversely bent corner 115, the corner 115 can abut against the outer side of the extension ring 21 when the anti-pry ring 11 is installed on the bottleneck, thereby further improving the installation stability between the anti-pry ring 11 and the bottleneck.

[0042] like Figure 6As shown, in this embodiment, an angle α is set between the second ring body 111 and the central axis of the anti-pry ring 11, and the range of the angle α is 15°≥α≥0°. By setting the angle α, the assembly accuracy requirement between the anti-pry ring 11 and the bottleneck can be weakened, and by limiting the range of the angle α, the fit effect between the second ring body 111 and the extension ring 21 can be effectively guaranteed, that is, the anti-pry ring 11 can be effectively prevented from being disassembled from the angle by tools such as steel pliers, thereby preventing people from seeking huge profits by removing the bottle cap and replacing inferior wine.

[0043] like Figure 6 As shown, the anti-pry ring 11 further includes a ring body 3 114, which is formed by extending outward along one end of the ring body 1 112 away from the ring body 2 111. The ring body 3 114 is a variable diameter structure, and the minimum outer diameter of the ring body 3 114 is the same as the outer diameter of the ring body 1 112. By setting the ring body 3 114 as the above structure, the minimum inner diameter of the ring body 3 114 is also greater than or equal to the outer diameter of the bottleneck, so that when the anti-pry ring 11 is inserted into the bottleneck by stamping, it can be inserted smoothly, thereby improving the assembly stability between the anti-pry ring 11 and the bottleneck.

[0044] See also Figure 7-9 As shown, the end face of the bottleneck extends outward from the convex ring 1 24 to form an extension ring 21 whose outer diameter is smaller than that of the convex ring 1 24. The second ring body 111 fits on the outer side of the extension ring 21, and the outermost edge of the second ring body 111 is flush with the end face of the extension ring 21. In the utility model, by providing the extension ring 21, and the end of the extension ring 21 away from the bottleneck is flush with the end of the second ring body 111 away from the anti-pry ring 11, the problem that the anti-pry ring 11 can be removed from the bottle mouth by steel pliers due to the gap between the steel ring and the bottle mouth in the prior art can be effectively solved, so as to exchange inferior wine and replace the counterfeit wine bottle cap. Specifically, the utility model sets the extension ring 21 and the second ring body 111 on the anti-pry ring 11 to be flush, and the second ring body 111 is attached to the outside of the extension ring 21, so that there is no point of force between the anti-pry ring 11 and the extension ring 21. Therefore, the anti-pry ring 11 improved by the utility model cannot be removed from the gap between the second ring body 111 and the extension ring 21 by tools such as steel pliers. If the anti-pry ring 11 is forcibly removed, the extension ring 21 will be broken, so that the bottle mouth and the bottle cap cannot be sealed, so that even if a new bottle cap is installed, wine leakage will occur. Therefore, the utility model can quickly determine whether the wine in the bottle has been replaced by whether there is wine leakage, which can effectively prevent some people from making huge profits by putting inferior wine into old wine bottles through such means.

[0045] The length of the extension ring 21 is 2 mm to 3 mm. The end of the extension ring 21 away from the protruding ring 1 24 is a smooth rounded structure.

[0046] Preferably, the length of the extension ring 21 is 2.5 mm.

[0047] like Fig. 9 As shown, the cross-section of the convex ring 24 is a trapezoidal structure, and the upper bottom surface of the trapezoid is arranged on a side close to the extension ring 21, so that the inclined surface of the trapezoid is formed by expanding downward from one side of the extension ring 21, which is convenient for quickly installing the anti-pry ring 11 on the bottleneck by stamping, thereby improving its installation efficiency.

[0048] like Fig. 9 As shown, the bottleneck also includes a bottleneck body 23 and a convex ring 25, the convex ring 25 is sleeved on the outer side of the bottleneck body 23 and the convex ring 25 is arranged on the side away from the extension ring 21. There is a distance between the convex ring 25 and the convex ring 1 24. The convex ring 25, the bottleneck body 23 and the convex ring 1 24 are able to form a limiting groove 22, and the limiting groove 22 is suitable for limiting the buckle 116. The anti-pry ring 11 can be firmly installed on the bottleneck, thereby realizing its anti-pry function. The bottleneck body 23 and the extension ring 21 are an integrated structure, and the bottleneck body 23 and the extension ring 21 have the same diameter.

[0049] like Fig.10 As shown, the bottle cap also includes an outer cover assembly 12, a steel buckle 13 and an inner plug 14. The steel buckle 13 is arranged on the outside of the anti-pry ring 11. The steel buckle 13 is integrally connected with the anti-pry ring 11 by injection molding. The inner plug 14 is arranged inside the steel buckle 13. One end of the inner plug 14 is inserted into the bottleneck body 23 to ensure that the liquid in the bottle does not leak and improve the sealing of the bottle cap. The outer cover assembly 12 includes an outer cover 121 and an outer cover 2 122. The outer cover 121 is installed on the upper end of the steel buckle 13. The outer cover and the steel buckle 13 are connected by a threaded connection, so that in normal use, the liquid can be poured out through the bottleneck and the liquid outlet of the inner plug 14 by unscrewing the outer cover. The outer cover 2 122 is sleeved on the lower end of the steel buckle 13, and the contact surfaces of the outer cover 121 and the outer cover 2 122 fit each other.

[0050] The outer cover 121 and the outer cover 2 122 can be connected by a thin plastic piece. When the outer cover and the steel buckle 13 are unscrewed, the plastic piece between the outer cover 121 and the outer cover 2 122 breaks, that is, the outer cover 121 can be unscrewed from the inner plug 14, so that the liquid can be poured out of the bottle.

[0051] Example 2

[0052] See also Fig.11 As shown, the present embodiment provides a bottle, the structure of which is substantially the same as that of the bottle in the first embodiment, except for the specific structures of the second ring body 111 and the reducing ring 113.

[0053] In this embodiment, the cross section of the reducer ring 113 is an arc-shaped structure, which is bent from the upper end of the ring body 112 toward the central axis of the anti-pry ring 11. The second ring body 111 is a ring body with an equal diameter structure, and the second ring body 111 is vertically arranged. The outer diameter of the second ring body 111 is the same as the minimum diameter of the reducer ring 113. The second ring body 111 is formed by extending upward along the end of the reducer ring 113 away from the first ring body 112. The inner wall of the second ring body 111 fits the outer wall of the extension ring 21, so that there is no gap between the second ring body 111 and the extension ring 21, so that personnel cannot remove the anti-pry ring 11 from the bottleneck from the second ring body 111 by tools such as steel pliers. If the anti-pry ring 11 is removed from the second ring body 111, the bottleneck will be damaged, so that even if a new bottle cap is installed, wine leakage will occur.

[0054] Example 3

[0055] See also Fig.12 As shown, the present embodiment provides a bottle, the structure of which is substantially the same as that of the bottle in the first embodiment, except for the specific structures of the second ring body 111 and the reducing ring 113.

[0056] In this embodiment, the cross section of the reducer ring 113 is an arc-shaped structure, one end of the reducer ring 113 is connected to the ring body 1 12, and the other end of the reducer ring 113 is connected to the ring body 2 111. The length of the ring body 1 12 along the axial direction of the anti-pry ring 11 is greater than the length of the ring body 1 112 along the axial direction of the anti-pry ring 11 in the embodiment. The ring body 2 111 is a ring sheet, and the ring body 2 111 is horizontally arranged. In other words, the reducer ring 113 of this embodiment can actually be regarded as a chamfered ring body formed at the connection between the ring body 1 12 and the ring body 2 111.

[0057] In this embodiment, the minimum inner diameter of the second ring body 111 abuts against the outer diameter of the extension ring 21, and the upper surface of the second ring body 111 is flush with the upper surface of the extension ring 21. By providing the reducing ring 113 and the second ring body 111 of the above structure, the reducing ring 113 and the second ring body 111 can be wrapped around the outside of the extension ring 21, so that there is no point of force between the anti-pry ring 11 and the extension ring 21, and people cannot remove the anti-pry ring 11 through the space between the second ring body 111 and the extension ring 21, thereby improving the anti-pry effect of the entire anti-pry ring 11.

[0058] Example 4

[0059] See also Fig.13 As shown, the present embodiment provides a bottle, the structure of which is substantially the same as that of the bottle in the first embodiment, except for the specific structures of the second ring body 111 and the reducing ring 113.

[0060] In this embodiment, the reducing ring 113 and the second ring body 111 can be regarded as an integral structure, and one end thereof is bent from the first ring body 112 to the outer diameter of the extension ring 21, and during the bending process, it is necessary to ensure that the outermost edge of the second ring body 111 is flush with the end surface of the extension ring 21. Thus, the reducing ring 113 and the second ring body 111 can wrap the gap between the first ring body 112 and the extension ring 21, so that people cannot dismantle the anti-pry ring 11 through the gap between the second ring body 111 and the extension ring 21, which greatly improves the anti-pry effect of the anti-pry ring 11.

[0061] Example 5

[0062] See also Fig.14 As shown, the present embodiment provides a bottle, the structure of which is substantially the same as that of the bottle in the first embodiment, except for the specific structures of the second ring body 111 and the reducing ring 113.

[0063] In this embodiment, the cross section of the reducer ring 113 is an arc-shaped structure, and the reducer ring 113 is formed by bending from the end surface of the ring body 1 12 toward the central axis direction of the anti-pry ring 11. The cross section of the ring body 2 111 is an inverted L-shaped structure. One end of the ring body 2 111 is connected to the reducer ring 113, and the other end of the ring body 2 111 abuts against the outer side of the extension ring 21, and the upper end surface of the ring body 2 111 is flush with the end surface of the extension ring 21. By setting the reducer ring 113 and the ring body 2 111 to the structure of this embodiment, there is no fulcrum between the anti-pry ring 11 and the extension ring 21, and personnel cannot remove the anti-pry ring 11 through the space between the ring body 2 111 and the extension ring 21, thereby improving the anti-pry effect of the entire anti-pry ring 11.
