Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing accessories for packaging containers, in particular to an anti-counterfeiting closure for steel drums. Background Technique

[0002] As is well known, steel drum containers are widely used in industries such as petroleum, chemical industry, pesticides, and food to package liquid products. These steel drums for packaging liquid products must be in their original state before final use, and the closures on the steel drums are not allowed to be opened. However, the steel drum closures produced according to the current national standard GB132151-2008 can be reused repeatedly, and there is no difference before and after opening. Even if the closure is opened, the liquid product in the steel drum is replaced, or counterfeit products are injected into an empty steel drum, it cannot be detected before use, which has brought great negative impacts to the manufacturers and caused great losses.

[0003] After retrieval, the anti-counterfeiting closure for steel drums disclosed in the patent application No. CN201020647565.6 includes a barrel plug, and a cylindrical anti-counterfeiting ring is arranged on the barrel plug. The anti-counterfeiting ring is connected to the barrel plug through a connecting plate. The number of connecting plates is four, and a plurality of notches are evenly distributed on the side wall of the anti-counterfeiting ring. The anti-counterfeiting closure uses an anti-counterfeiting ring connected to the cover. After opening, the anti-counterfeiting ring remains on the steel drum, making the closure unable to be reused.

[0004] In the above patent, after the barrel plug is opened, the anti-counterfeiting ring on the barrel plug will be damaged, which indeed has a certain degree of recognition and can play a certain anti-counterfeiting role. However, for counterfeiters, if a brand-new (the anti-counterfeiting ring is not damaged) barrel plug is replaced, the anti-counterfeiting ability will be reduced.

[0005] Therefore, there is an urgent need to develop a device for anti-counterfeiting of steel drum containers. Content of the Utility Model

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1-8 , an anti-counterfeiting closure for a steel barrel of the present utility model, comprising a barrel body 1 and a barrel opening 2 provided on the barrel body 1. A sealing cover 3 is installed on the barrel opening 2. A retaining edge 4 is provided on the outer wall of the sealing cover 3. A fixing ring 5 surrounding the barrel opening 2 is fixedly provided on the barrel body 1. An anti-counterfeiting retaining ring 6 is connected inside the fixing ring 5. The inner diameter of the anti-counterfeiting retaining ring 6 gradually decreases from top to bottom. The smallest inner diameter of the anti-counterfeiting retaining ring 6 is greater than the outer diameter of the retaining edge 4. A plurality of anti-counterfeiting retaining pieces 7 are provided on the fixing ring 5. One end of the anti-counterfeiting retaining piece 7 is fixedly connected to the fixing ring 5, and the other end of the anti-counterfeiting retaining piece 7 is detachably connected to the anti-counterfeiting retaining ring 6.

[0027] The smallest inner diameter of the anti-counterfeiting retaining ring 6 is slightly greater than the outer diameter of the retaining edge 4. The bottom of the retaining edge 4 is chamfered. The upper surface of the bottom of the anti-counterfeiting retaining ring 6 is chamfered. When the retaining edge 4 moves downward, it will press down the anti-counterfeiting retaining ring 6, causing a small downward deformation of the anti-counterfeiting retaining ring 6. The small deformation of the anti-counterfeiting retaining ring 6 will not cause the anti-counterfeiting retaining piece 7 and the anti-counterfeiting retaining ring 6 to break.

[0028] When the sealing cover 3 is opened, the upward movement of the retaining edge 4 will cause a large upward deformation of the anti-counterfeiting retaining ring 6. The large upward deformation of the anti-counterfeiting retaining ring 6 will cause the breakage between the plurality of anti-counterfeiting retaining pieces 7 and the anti-counterfeiting retaining ring 6. There is an obvious mechanical anti-counterfeiting mark before and after opening, playing an anti-counterfeiting role.

[0029] Among them, anti-slip lines are provided on the outer wall of the sealing cover 3, playing an anti-slip role.

[0030] In summary, for this steel drum anti-counterfeiting closure, during production, materials are injected into the drum body 1 from the drum opening 2. After the injection is completed, the sealing cover 3 is placed on the drum opening 2. During the process of placing the sealing cover 3 on the drum opening 2, the retaining edge 4 moves downward and presses down the anti-counterfeiting retaining ring 6, causing the anti-counterfeiting retaining ring 6 to deform slightly downward. The slight deformation of the anti-counterfeiting retaining ring 6 will not cause the anti-counterfeiting tab 7 and the anti-counterfeiting retaining ring 6 to break;

[0031] When the sealing cover 3 is opened, the upward movement of the retaining edge 4 will cause the anti-counterfeiting retaining ring 6 to deform significantly upward. The significant upward deformation of the anti-counterfeiting retaining ring 6 will cause the breakage between multiple anti-counterfeiting tabs 7 and the anti-counterfeiting retaining ring 6. There are obvious mechanical anti-counterfeiting marks before and after opening, and the difficulty of restoring the deformation of the anti-counterfeiting retaining ring 6 and the breakage of the anti-counterfeiting tab 7 is significantly increased. Therefore, it has good anti-counterfeiting ability.
