Description

Technical Field

[0001] The utility model relates to the technical field of packaging containers, in particular to an anti-counterfeiting and anti-mis-opening plastic barrel. Background Art

[0002] Plastic barrels are used to store solid particles or solutions such as food, medicine, and paint, and are widely used in various fields. Plastic barrels generally consist of a barrel body and a lid, which is detachably connected to the barrel body via threads or snaps. To facilitate quick opening, more and more plastic barrels are adopting snap-on connections, which presents numerous problems. For example, when children come into contact with a plastic barrel, out of curiosity or restlessness, they may simply pull the latch and slot to release the connection, thereby accidentally opening the lid. This exposure, or even accidental ingestion of toxic and hazardous substances within the barrel, can significantly impact their health and pose a significant safety hazard. Another example is that simple snap-on connections lack certain anti-counterfeiting features. Once the barrel is empty, unscrupulous merchants may recycle and refill the contents, refilling them with lower-quality products, and then re-covering the barrel, passing them off as genuine goods. Therefore, anti-counterfeiting is a crucial factor that must be considered during the production of plastic barrels. Utility Model Content

[0003] The technical problem to be solved by the present invention is that in the prior art, plastic barrels lack an anti-mistaken opening structure, which poses certain safety hazards and has no anti-counterfeiting function. Based on this, the present invention provides a plastic barrel with anti-counterfeiting and anti-mistaken opening functions.

[0004] The technical solution adopted by the utility model to solve its technical problems is: an anti-counterfeiting and anti-misopening plastic barrel, comprising a barrel body and a barrel cover detachably arranged at the open end of the barrel body, a locking tongue being arranged on the edge of the barrel cover, the locking tongue and the barrel body being connected by a plurality of snap structures, a rotating ring being rotatably installed on the outside of the barrel body below the locking tongue, the upper surface of the rotating ring being fitted with the lower end of the locking tongue, an operating space being formed between the locking tongue and the barrel body, a slot being arranged on the rotating ring and communicating with the operating space, the rotating ring being connected to the barrel body by a connecting point, and the connecting point can be broken by rotating the rotating ring relative to the barrel body, so that the slot is aligned with the snap structure.

[0005] Furthermore, the snap-fit ​​structure includes an outer protrusion and an inner protrusion ring, the outer protrusion is fixedly connected to the outer wall of the barrel body, the inner protrusion ring is connected to the inner wall of the lock tongue, and the bottom of the outer protrusion can be snap-fitted with the top of the inner protrusion ring.

[0006] Furthermore, the locking tongue is an annular structure, the inner convex ring is an annular structure, the outer protrusion is an arc-shaped structure, there are multiple outer protrusions, and they are evenly arranged along the circumference of the barrel body.

[0007] Furthermore, the number of the slots is the same as the number of the external protrusions and corresponds one to one.

[0008] Furthermore, the bottom of the inner convex ring is set as a slope, the slope is smoothly transitioned to the inner wall of the lock tongue, and the slope is tilted from top to bottom and from inside to outside.

[0009] Furthermore, an upper limit ring and a lower limit ring are provided on the outer wall of the barrel body protruding radially outward along the barrel body, and the rotating ring is rotatably mounted on the outside of the barrel body, with the upper surface of the rotating ring fitting against the upper limit ring and the lower surface of the rotating ring fitting against the lower limit ring.

[0010] Furthermore, the connection point is connected between the rotating ring and the lower limit ring, and the connection point, the rotating ring and the lower limit ring are fixedly connected by hot melt welding.

[0011] Furthermore, a first mark is provided on the outer circumferential surface of the rotating ring, and a second mark is provided on the outer wall of the locking tongue.

[0012] Furthermore, a mounting groove is formed on the upper surface of the barrel body in a downward depression, a sealing member is installed in the mounting groove, and the barrel cover squeezes the sealing member.

[0013] The beneficial effects of the present invention are as follows: when opening the lid of the anti-counterfeiting and anti-mistaken-opening plastic barrel of the present invention, it is necessary to first rotate the rotating ring with force to break the connection point between the rotating ring and the barrel body, and continue to rotate the rotating ring to move the slot to align with the buckle structure. At this time, the user can insert his finger into the operating space through the slot and push the lock tongue outward to release the snap connection between the lock tongue and the barrel body, thereby further removing the barrel lid. After the connection point is broken, it cannot be restored, which has a good anti-counterfeiting effect. At the same time, children cannot release the connection between the lock tongue and the barrel body by a simple pulling action, which plays a role in preventing the lid from being opened by mistake, eliminates safety hazards, and is suitable for popularization and use.

[0020] The present invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0021] See also Figures 1-4 The utility model provides an anti-counterfeiting and anti-misopening plastic barrel, comprising a barrel body 1 and a barrel cover 2. The barrel body 1 is a hollow barrel structure with an opening at the upper end. The barrel cover 2 is detachably connected to the open end of the barrel body 1. A locking tongue 21 is provided on the edge of the barrel cover 2. The locking tongue 21 and the barrel body 1 are connected by multiple snap structures 3. A rotating ring 4 is rotatably installed on the outside of the barrel body 1 below the locking tongue 21. The upper surface of the rotating ring 4 is in contact with the lower end of the locking tongue 21. An operating space 210 is formed between the locking tongue 21 and the barrel body 1. A slot 41 communicating with the operating space 210 is provided on the rotating ring 4. The rotating ring 4 is connected to the barrel body 1 through a connecting point 42. Rotating the rotating ring 4 relative to the barrel body 1 can break the connecting point 42 and align the slot 41 with the snap structure 3.

[0022] The anti-counterfeiting and anti-mistaken-opening plastic bucket of this utility model utilizes multiple snap-fit ​​structures 3 to securely connect the locking tongue 21 to the bucket body 1, thereby achieving a fixed connection between the bucket lid 2 and the bucket body 1. In the initial state, the slots 41 and the snap-fit ​​structures 3 are offset. When a user inserts their finger through the slot 41 into the operating space 210 and pushes outward against the locking tongue 21, the snap-fit ​​structures 3 cannot be released, preventing further opening of the bucket lid 2. This prevents children from accidentally opening the bucket lid 2, eliminating the safety hazards posed by such accidental opening.

[0023] When the user needs to open the lid, the user rotates the rotating ring 4 relative to the barrel body 1 to break the connection point 42 between the two. Then, the user continues to rotate to move the slot 41 to align with the buckle structure 3. At this time, the user inserts a finger through the slot 41 into the operating space 210 and pushes the lock tongue 21 outward to release the buckle structure 3 at the corresponding position, thereby further removing the barrel lid 2. In addition, once the connection point 42 is broken, it cannot be restored, which has a good anti-counterfeiting effect.

[0024] Please refer again Figure 2 In this embodiment, the snap-fit ​​structure 3 includes an outer protrusion 31 and an inner protrusion ring 32. The outer protrusion 31 is fixedly connected to the outer wall of the barrel body 1, and the inner protrusion ring 32 is connected to the inner wall of the lock tongue 21. When the snap-fit ​​structure 3 is in a snap-fit ​​state, the bottom of the outer protrusion 31 and the top of the inner protrusion ring 32 are snap-fitted to each other.

[0025] The locking tongue 21 is an annular structure, the inner convex ring 32 is an annular structure, and the outer protrusion 31 is an arc-shaped structure. There are multiple outer protrusions 31, and they are evenly arranged along the circumference of the barrel body 1. The number of slots 41 is the same as the number of outer protrusions 31, and they correspond one to one. Rotating the rotating ring 4 can align the slots 41 with the corresponding outer protrusions 31. At this time, by pushing the locking tongue 21 from the inside to the outside with your fingers, the inner convex ring 32 can be separated from the outer protrusion 31 at the corresponding position, thereby facilitating the removal of the barrel cover 2 from the barrel body 1. As a preferred embodiment, the number of slots 31 and the number of outer protrusions 31 are both three.

[0026] Furthermore, the bottom of the inner convex ring 32 is provided with a sloped surface 321, which smoothly transitions to the inner wall of the locking tongue 21. The sloped surface 321 is arranged to be inclined from the inside to the outside from the top and bottom. Thus, when closing the lid 2, one only needs to press the lid 2 downward to allow the locking tongue 21 to fit over the open end of the barrel body 1. Under the action of the sloped surface 321, the locking tongue 21 is squeezed outward by the outer protrusion 31, and finally the outer protrusion 31 is engaged with the inner convex ring 32.

[0027] In addition, the barrel body 1 and the outer protrusion 31 are integrally formed, and the barrel cover 2, the locking tongue 21, and the inner protrusion ring 32 are integrally formed, which facilitates processing and helps control production costs. Furthermore, the barrel body 1 and the barrel cover 2 are both made of plastic to have elastic deformation capabilities, thereby facilitating the engagement of the snap structure 3.

[0028] In the present embodiment, an upper limit ring 11 and a lower limit ring 12 are provided on the outer wall of the barrel body 1, protruding radially outward along the barrel body 1. The upper limit ring 11 is located above the lower limit ring 12. The rotating ring 4 is a hollow ring structure. The rotating ring 4 is rotatably mounted on the outside of the barrel body 1. The upper limit ring 11 is located above the rotating ring 4 and fits with the upper surface of the rotating ring 4. The lower limit ring 12 is located below the rotating ring 4 and fits with the lower surface of the rotating ring 4. The upper limit ring 11 and the lower limit ring 12 limit the rotating ring 4. In this way, while ensuring that the limit ring 4 can rotate relative to the barrel body 1, it also avoids the rotating ring 4 from moving axially along the barrel body 1. In the present embodiment, the upper limit ring 11 and the lower limit ring 12 are both made of plastic, and the two are fixedly connected to the barrel body 1 by ultrasonic welding.

[0029] In addition, the upper surface of the rotating ring 4 fits with the lower end of the lock tongue 21, ensuring that there is no gap between the upper surface of the rotating ring 4 and the lower end of the lock tongue 21 for fingers to insert into the operating space 210, thereby preventing children's fingers from opening the lock tongue 21 without passing through the slot 41.

[0030] Furthermore, the connection point 42 is made of plastic, and the connection point 42 is connected between the rotating ring 4 and the lower limit ring 12. The connection point 42 and the rotating ring 4 and the lower limit ring 12 are fixedly connected by hot melt welding. Since there is only one connection point 42, when the rotating ring 4 is rotated forcefully relative to the barrel body 1, the connection point 42 can be pulled apart, thereby further rotating the rotating ring 4.

[0031] Please combine Figure 2 、 Figure 4 In this embodiment, a first mark 43 is provided on the outer circumference of the rotating ring 4, and a second mark 211 is provided on the outer wall of the lock tongue 21. By rotating the rotating ring 4, the first mark 43 and the second mark 211 can be aligned or staggered. When the first mark 43 and the second mark 211 are aligned, the slot 41 is aligned with the outer protrusion 31. At this time, the rotating ring 4 is rotated into position, and the user can reach into the operating space 210 to push the lock tongue 21 outward, thereby unlocking the buckle structure 3, greatly facilitating user operation. The first mark 43 and the second mark 211 can be structures such as protrusions, grooves, or vertical strips, which are not limited here.

[0032] Please combine Figure 2 、 Figure 3 As a preferred embodiment, a mounting groove 13 is formed on the upper surface of the barrel body 1, and a sealing member 14 is installed in the mounting groove 13. The sealing member 14 is squeezed by the barrel cover 2 when the barrel cover 2 is installed, thereby sealing the connection between the barrel body 1 and the barrel cover 2. The sealing member 14 can be made of silicone or rubber material, which is not limited here.

[0033] The anti-counterfeiting and anti-mistaken-opening plastic bucket of the present invention has a good anti-counterfeiting and anti-mistaken-opening operation. When opening the lid, it is necessary to first rotate the rotating ring 4 with force to break the connection point 42 between the rotating ring 4 and the barrel body 1, and continue to rotate the rotating ring 4 to move the slot 41 to align with the buckle structure 3. At this time, the user can insert his finger into the operating space 210 through the slot 41 and push the lock tongue 21 outward to release the snap connection between the lock tongue 21 and the barrel body 1, so as to further remove the barrel lid 2. After the connection point 42 is broken, it cannot be restored, which has a good anti-counterfeiting effect. At the same time, children cannot release the connection between the lock tongue 21 and the barrel body 1 by a simple pulling action, which plays a role in preventing the lid from being opened by mistake, eliminates safety hazards, and is suitable for popularization and use.

[0034] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the scope of the present invention. The technical scope of this utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
