Description

Technical Field

[0001] The utility model relates to the technical field of packaging barrels, in particular to a one-time packaging structure and a packaging barrel. Background Art

[0002] Packaging drums refer to a variety of barrel-type packaging containers, often used to hold various liquid products. Based on their material, packaging drums can be categorized as plastic, metal, or iron, each used to package and transport products with different characteristics.

[0003] The barrel and lid of a packaging barrel are mostly injection-molded, with the lid attached to the upper end of the barrel. Because the threaded connection between the barrel and lid lacks sealing performance, a snap-on or snap-on method is often used for packaging. For example, the inner ridges on the inner circumference of the lid and the outer flange on the barrel circumference cooperate to press the lid onto the barrel; or the outer edge of the lid is bent inward and extends deep into the barrel, with the outer curl of the lid pressing against the outer curl of the barrel.

[0004] Although the above packaging method can achieve a seal between the barrel body and the barrel lid, it is often necessary to pry open the barrel lid when opening the packaging barrel, which makes opening difficult. In addition, whether it is the first time or multiple times, the effect after the lid is installed is the same as the first packaging. Users cannot determine whether the product in the packaging barrel has been opened, which may cause disputes. Utility Model Content

[0005] In order to achieve a seal between the barrel body and the barrel cover, and at the same time facilitate opening and judging whether the packaging barrel is unsealed, the present application provides a one-time packaging structure and a packaging barrel.

[0006] The present application provides a one-time packaging structure and a packaging barrel that adopts the following technical solutions:

[0007] In the first aspect, the present application provides a one-time packaging structure, comprising a barrel body and a barrel cover, wherein the barrel cover is mounted on the upper end surface of the barrel body, and further comprises a sealing ring and an insert, wherein the sealing ring comprises a packaging annular surface, a snap-locking structure and a fixing portion, wherein the packaging annular surface surrounds the connection between the barrel body and the barrel cover, the snap-locking structure is rotatably connected to the packaging annular surface, and the fixing portion is connected to the packaging annular surface. When the packaging is completed, the snap-locking structure and the fixing portion jointly open a accommodating cavity, and the insert is arranged in the accommodating cavity.

[0008] By adopting the above technical solution, when the packaging barrel is sealed, the barrel lid is installed on the upper end surface of the barrel body, and the sealing ring surrounds the connection between the barrel lid and the barrel body. The locking mechanism is rotated, and the locking mechanism moves toward the fixed portion. At this time, the barrel lid and the barrel body are clamped together using the sealing ring. The plug-in is inserted into the receiving cavity formed by the locking mechanism and the fixed portion, and the locking mechanism is locked. At this point, the packaging barrel can be unsealed. At the same time, the packaging barrel can be opened by simply rotating the locking mechanism back, which is convenient. Rotating the locking mechanism will damage the plug-in. The plug-in status can be used to determine whether it has been opened, thus achieving anti-theft and anti-counterfeiting functions.

[0009] Optionally, the locking structure includes a first fixing seat, a second fixing seat, a handle and a connecting rod, the first fixing seat and the second fixing seat are both connected to the packaging ring surface, the handle is rotatably connected to the first fixing seat, and the two ends of the connecting rod are respectively rotatably connected to the second fixing seat and the handle, and when packaging, the handle rotates toward the fixed part, and the accommodating cavity is opened in the handle and the fixed part.

[0010] By adopting the above technical solution, the handle is rotated so that the end of the handle away from the connecting rod moves in the direction away from the connecting rod, and drives the connecting rod to rotate. At this time, the sealing ring holds the barrel body and the barrel cover tightly to achieve the sealing of the packaging barrel.

[0011] Optionally, the packaging ring surface is provided with a retractable fracture, the locking structure is used to adjust the size of the fracture, the first fixing seat and the second fixing seat are respectively located on both sides of the fracture, and the fixing part is located on the same side of the first fixing seat.

[0012] By adopting the above technical solution, by arranging the first fixing seat and the second fixing seat at the two ends of the fracture respectively, when the handle and the connecting rod are rotated, the two ends of the packaging ring surface approach each other, the fracture is reduced, and the sealing ring undergoes elastic deformation to hold the barrel cover and the barrel body tightly. When the fracture expands, it is convenient to remove the sealing ring and the barrel cover.

[0013] Optionally, the handle is provided with a placement groove, through holes are provided on both sides of the handle, and openings are provided in the middle of the fixing part and the packaging ring surface. When the packaging is completed, the fixing part is located in the placement groove, and the positions of the through holes and the openings correspond to each other to form the accommodating cavity.

[0014] By adopting the above technical solution, the provision of the accommodating cavity facilitates the insertion of the plug-in, and the plug-in can further lock the handle.

[0015] Optionally, the packaging ring surface is provided with an upper flange and a lower flange, the upper end surface of the barrel body is provided with a curling edge, the barrel cover is provided with an edge, the upper flange abuts against the upper end surface of the edge, and the lower flange abuts against the lower end surface of the curling edge.

[0016] By adopting the above technical solution, the arrangement of the upper flange and the lower flange makes it easier to determine the position of the packaging ring surface, while enhancing the sealing performance.

[0018] By adopting the above technical solution, the arrow facilitates the insertion of the plug-in into the accommodating cavity, and is arranged to abut against the middle part of the side wall of the accommodating cavity. The plug-in cannot be pulled out of the accommodating cavity and will be damaged when the packaging barrel is opened, thereby realizing the anti-theft and anti-counterfeiting functions.

[0019] Optionally, the pointed portion and the middle portion are both provided with an elastic strip, one end of the elastic strip is connected to the plug-in, and the free end of the elastic strip is inclined toward a side away from the plug-in.

[0020] By adopting the above technical solution, the provision of the elastic strip ensures that the plug-in can be inserted into the accommodating cavity but cannot be pulled out.

[0021] In a second aspect, the present application provides a packaging barrel, comprising the above-mentioned one-time packaging structure.

[0022] In summary, this application has at least one of the following beneficial effects:

[0023] 1. When sealing the barrel, the lid is attached to the upper end of the barrel body, with the sealing ring surrounding the connection between the lid and the barrel body.

The insert is inserted into the cavity formed by the latch mechanism and the fixed portion, locking the latch mechanism. The barrel can now be unsealed. The barrel can be opened by simply rotating the latch mechanism back, making it easy to open. Rotating the latch mechanism damages the insert, but the insert's status allows users to determine whether it has been opened, thus providing anti-theft and anti-counterfeiting features.

[0024] 2. When the handle and the connecting rod are rotated, the two ends of the sealing ring surface approach each other, the fracture is reduced, and the sealing ring undergoes elastic deformation to hold the barrel cover and the barrel body tightly. When the fracture is expanded, it is convenient to remove the sealing ring and the barrel cover. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] The embodiment of the present application discloses a one-time packaging structure and a packaging barrel. Figure 1 As shown, a disposable packaging structure includes a barrel body 1 and a barrel lid 2. The barrel lid 2 is mounted on the upper end surface of the barrel body 1. The upper end surface of the barrel body 1 is provided with a curling edge 11, and the barrel lid 2 is provided with an edge 21. The interior of the barrel lid 2 is disposed within the barrel body 1, and the curling edge 11 and the edge 21 are stacked together. The packaging structure also includes a sealing ring 3 and an insert 4. The sealing ring 3 includes a sealing ring surface 31, a locking structure, and a fixing portion 32. The sealing ring surface 31 is provided with a retractable fracture 6. The locking structure is used to adjust the size of the fracture 6. The fixing portion 32 is used to form a receiving cavity 5 with the locking structure. The insert 4 is inserted into the receiving cavity 5 to fix the locking structure.

[0034] like Figure 2-Figure 4 As shown, the sealing ring surface 31 surrounds the connection between the barrel body 1 and the barrel lid 2, and the sealing ring surface 31 can undergo elastic deformation. When the incision 6 of the sealing ring surface 31 is reduced, the two ends of the sealing ring surface 31 at the incision 6 gradually approach each other. At this time, the sealing ring 3 tightly embraces the barrel body 1 and the barrel lid 2, achieving a seal on the packaging barrel. As the incision 6 increases, the sealing ring surface 31 expands, making it easier to remove the sealing ring surface 31 and the barrel lid 2 and open the packaging barrel. The sealing ring surface 31 is provided with an upper flange 61 and a lower flange 62. The upper flange 61 abuts the upper end surface of the edge 21, and the lower flange 62 abuts the lower section of the curling edge 11. Therefore, the upper flange 61 and the lower flange 62 allow the sealing ring surface to wrap around the edge 21 and the curling edge 11, fixing the position of the sealing ring surface and enhancing the sealing performance.

[0035] The snap-lock structure is rotatably connected to the packaging annular surface. The snap-lock structure includes a first fixing seat 33 and a second fixing seat 34 that are threadedly connected to the packaging annular surface by bolts. The first fixing seat 33 and the second fixing seat 34 are respectively located on either side of the position of the fracture 6. The first fixing seat 33 is rotatably connected to a handle 35, and the second fixing seat 34 is rotatably connected to a connecting rod 36. The end of the connecting rod 36 away from the second fixing seat 34 is rotatably connected to the handle 35. When packaging the packaging barrel, the handle 35 is rotated toward the side away from the connecting rod 36, which drives the connecting rod 36 to rotate. The rotation of the connecting rod 36 drives the two ends of the packaging annular surface to gradually approach each other, reducing the fracture 6, and the packaging annular surface tightly embraces the barrel body 1 and the barrel lid 2. At this time, part of the position of the handle 35 coincides with part of the position of the connecting rod 36, and the two sides of the handle 35 are located in the middle of the connecting rod 36. The handle 35 and the fixing portion 32 form a accommodating cavity 5. When the packaging barrel needs to be opened, the handle 35 is rotated in the opposite direction, the fracture 6 of the sealing ring surface is enlarged, the two ends of the sealing ring surface are separated, and the sealing ring 3 loses its sealing performance, making it convenient to remove the sealing ring 3 and the barrel cover 2 to open the packaging barrel.

[0036] The fixing portion 32 is connected to the packaging annular surface and is located on the same side of the fracture 6 as the first fixing seat 33. The two ends of the fixing portion 32 are threadedly connected to the packaging annular surface by bolts. The middle position of the fixing portion 32 protrudes from the two ends, and an opening 53 is provided between the middle position of the fixing portion 32 and the packaging annular surface. The handle 35 is provided with a placement groove 51. When the packaging barrel is packaged, the handle 35 is rotated toward the fixing portion 32. After the packaging is completed, the fixing portion 32 is located in the placement groove 51. Through holes 52 are provided on the upper and lower sides of the handle 35. At this time, the position of the through holes 52 corresponds to the position of the opening 53, and together they constitute a receiving chamber 5. The plug-in 4 is placed in the receiving chamber 5. The insertion of the plug-in 4 restricts the locking structure to prevent the locking mechanism from automatically rebounding under the action of external force, causing the packaging barrel to lose its sealing performance.

[0037] like Figure 5 As shown, insert 4 is a disposable insert. Once inserted into cavity 5, it cannot be fully removed. When handle 35 is rotated in the opposite direction to open the packaging barrel, insert 4 may become damaged. The state of the resealed packaging barrel will differ from that of the first sealing. Therefore, the state of insert 4 can be used to determine whether the packaging barrel has been opened for the first time, providing anti-theft and anti-counterfeiting features and facilitating subsequent dispute resolution.

[0038] The specific structure of the plug-in 4 includes a pointed portion 41, a middle portion 42 and a terminal portion 43. The pointed portion 41 facilitates the insertion of the plug-in 4 into the accommodating cavity 5. The width of the pointed portion 41 is smaller than that of the accommodating cavity 5, so that the arrow portion can pass through the accommodating cavity 5. The middle portion 42 is located in the accommodating cavity 5. The pointed portion 41 and the accommodating cavity 5 are both provided with elastic strips. The elastic strips 44 are symmetrically arranged about the center line of the plug-in 4. One end of the elastic strip 44 is connected to the plug-in 4, and the other end is a free end. The elastic strip 44 is tilted, and the free end is tilted toward the side away from the center line of the plug-in 4. The elastic strip 44 can be elastically deformed to approach or move away from the center line of the plug-in 4. During insertion, the insertion of the middle portion 42 is achieved by the deformation of the elastic strip 44 close to the center line. After entering the accommodating cavity 5, the elastic strip 44 returns to its original shape and the elastic strip 44 abuts against the side wall of the accommodating cavity 5, so that the plug-in 4 can be fixedly inserted into the accommodating cavity 5 and cannot be completely pulled out. The cross section of the end portion 43 is set to be rectangular, and the width of the end portion 43 is greater than the width of the through hole 52, so that the end portion 43 abuts against the through hole 52 to achieve the connection between the plug 4 and the accommodating cavity 5.

[0039] The present application also discloses a packaging barrel, which includes the above-mentioned one-time packaging structure. The packaging barrel is also provided with handles on both sides of the barrel body 1 for convenient lifting.

[0040] The implementation principle of a one-time packaging structure in an embodiment of the present application is as follows: the barrel cover 2 is installed on the upper end surface of the barrel body 1, the interior of the barrel cover 2 is set inside the barrel body 1, the curling 11 and the edge 21 are stacked together, and the edge 21 and the curling 11 can be wrapped by the packaging ring surface. The handle 35 is rotated toward the side away from the connecting rod 36, which drives the connecting rod 36 to rotate, and drives the two ends of the packaging ring surface to gradually approach each other, the fracture 6 is reduced, and the packaging ring surface tightly embraces the barrel body 1 and the barrel cover 2. At this time, the two sides of the handle 35 are located in the middle of the connecting rod 36, and the position of the through hole 52 corresponds to the position of the opening 53 up and down, together forming a accommodating cavity 5. The plug-in 4 is inserted into the accommodating cavity 5 to realize the packaging of the packaging barrel.

[0041] This specific implementation manner is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the specific implementation manner as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
