Description

Technical Field

[0001] This utility model relates to the field of metal packaging barrel technology, specifically a wraparound metal packaging barrel that is easy to handle. Background Technology

[0002] Metal packaging drums are closed metal containers used for holding, transporting, and storing liquids, powders, or solid materials. They are commonly used in industries such as chemical, food, pharmaceutical, petroleum, paint, pesticide, and lubricant manufacturing. Made of metal materials such as steel, galvanized iron, aluminum alloy, or stainless steel, they possess good strength, sealing properties, and corrosion resistance. An existing sealing device for metal packaging drums used in food transportation (authorization notice number: CN220595493U) exhibits at least the following defects during use: 1. In non-encircling barrels, the entire load is borne by the thin walls, and the outer barrel is not reinforced with an outer frame or clamps. When transported, stacked, or subjected to external impacts, the barrel walls are prone to dents or bulges, affecting the sealing fit of the barrel lid threads. Therefore, an encircling metal packaging barrel is needed.

[0003] 2. The smooth surface and high center of gravity of the containers make them difficult to handle manually, easily leading to slipping, tipping, or operational injuries. This is especially problematic when filled with liquid, as the increased weight makes them ergonomically unfriendly. The lack of handles, grips, or casters requires two people or external support for each loading and unloading operation, hindering mass production and logistics. During handling and transportation, the inability to reliably secure the containers makes them prone to rolling and collisions, potentially damaging the walls, welds, or seals and causing leakage risks. Therefore, a more easily handled metal packaging container is needed. Utility Model Content

[0004] The main objective of this invention is to provide a wraparound metal packaging barrel that is easy to handle, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A convenient, wraparound metal packaging drum includes a metal drum body, a lid, and a switch handle. The lid is mounted on the metal drum body, and the metal drum body and lid are connected by the switch handle. A transport frame is mounted on the outer layer of the metal drum body. The transport frame includes a bottom ring, a vertical rod, multiple rings, and a top ring. The bottom ring has several hand gripping holes, and the top ring has several lifting rings.

[0006] Preferably, the vertical rods are evenly distributed along the outer circumference of the metal barrel and are welded to the bottom ring, multi-layer rings and top ring.

[0007] Preferably, the gripper hole has an elliptical opening structure and the edge is provided with an anti-slip rubber pad.

[0008] Preferably, an anti-slip pad layer is provided under the bottom ring of the transport frame.

[0009] Preferably, the switch handle adopts a rotary-locking structure, and the lid and metal body are quickly sealed and disassembled through a cam locking or quick-release mechanism.

[0010] Preferably, the metal barrel body has a double-layer structure, with an inner layer of stainless steel anti-corrosion layer and an outer layer of carbon steel reinforcing layer, and a heat insulation or heat preservation cavity can be formed between the two layers.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting hand gripping holes, it can be used for low-level horizontal handling, and it is also convenient for fine-tuning the posture when placing it at an angle, crossing steps, or loading / unloading goods onto or off vehicles. When used in conjunction with the top ring lifting point, the manual person is responsible for positioning and guiding, while the machine is responsible for lifting and lowering, forming a division of labor mode of "human guidance - machine lifting", which ensures safety and improves the overall handling efficiency.

[0012] 2. The lifting rings on the top ring provide a stable and predictable multi-point lifting and fixing interface for the barrel. When manually handling, it can be used with slings or simple lever hoists to form a closed force path. Operators no longer need to directly grasp the smooth barrel wall to complete lifting, lowering and repositioning, thus reducing the risk of slipping and falling when operating with wet hands, oil, or gloves.

[0017] Example Please see Figure 1-3 The present invention provides the following technical solution: A convenient, wraparound metal packaging drum includes a metal drum body 1, a drum lid 2, and a switch handle 3. The drum lid 2 is installed on the metal drum body 1, and the metal drum body 1 and the drum lid 2 are connected by the switch handle 3. A transport frame 4 is installed on the outer layer of the metal drum body 1. The transport frame 4 includes a bottom ring 401, a vertical rod 402, multiple rings 403, and a top ring 404. The bottom ring 401 is provided with a plurality of hand gripping holes 5, and the top ring 404 is provided with a plurality of lifting rings 6.

[0018] Specifically: The vertical rods 402 are evenly distributed along the outer periphery of the metal barrel 1 and are welded to the bottom ring 401, the multi-layer rings 403 and the top ring 404.

[0019] Specifically: the hand gripping hole 5 has an elliptical opening structure and the edge is provided with anti-slip rubber pads.

[0020] Specifically: an anti-slip pad layer is provided below the bottom ring 401 of the transport frame 4.

[0021] Specifically: The switch handle 3 adopts a rotary-locking structure, and the lid 2 and the metal barrel 1 are quickly sealed and disassembled through a cam locking or quick-release mechanism.

[0022] Specifically: The metal barrel body 1 has a double-layer structure, with an inner layer of stainless steel anti-corrosion layer and an outer layer of carbon steel reinforcement layer, and a heat insulation or heat preservation cavity can be formed between the two layers.

[0023] In this embodiment, a transport frame 4 is installed on the outer layer of the metal barrel body 1. The transport frame 4 includes a bottom ring 401, a vertical rod 402, a multi-layer ring 403, and a top ring 404. The bottom ring 401 is provided with a plurality of hand gripping holes 5. The vertical rod 402 is evenly distributed along the outer periphery of the metal barrel body 1 and is welded to the bottom ring 401, the multi-layer ring 403, and the top ring 404. The hand gripping holes 5 are elliptical opening structures with anti-slip rubber pads on the edges.

[0024] In terms of structural strength, the encircling design, through the placement of a handling frame 4 on the outside of the barrel, forms a closed force-bearing frame with the bottom ring 401, top ring 404, multi-layer rings 403, and vertical rod 402. The outer frame and barrel wall share external forces through multiple paths—surface, line, and point. During transportation or stacking, external impacts are first dispersed by the multi-layer rings 403 to the vertical rod 402, and then transmitted to the closed loop of the bottom ring 401 and top ring 404, avoiding local buckling and bulging caused by the stress on a single thin wall. The frame acts as a "clamp and circle stabilizer" for the barrel, significantly suppressing ellipticization, thus maintaining the roundness of the barrel and the coaxiality of the opening during long-term circulation. This ensures a continuous and stable engagement between the barrel lid 2 and the barrel opening threads, resulting in more uniform pressure on the sealing ring and improved durability. Even under extreme conditions such as improper forklift pushing, sudden vehicle braking, or loading / unloading collisions, the outer frame preferentially absorbs and disperses energy, while the barrel wall only bears the secondary load after peak reduction. This significantly reduces structural fatigue and the accumulation of microcracks, extending the overall barrel life.

[0025] In this embodiment, the gripping holes 5 are distributed circumferentially on the bottom ring 401, featuring elliptical openings with anti-slip rubber pads and rolled edges. This structure offers significant ergonomic benefits: the major axis of the ellipse aligns with the gripping direction, allowing the thumb and four fingers to form a symmetrical gripping surface, maintaining a neutral wrist position, and preventing excessive pronation or ulnar deviation of the forearm during handling; the rolled edges and pads together increase the contact area, reducing unit pressure and minimizing fatigue symptoms such as "hand strain" or "numbness" during prolonged gripping, thereby reducing the risk of misoperation and dropping the bucket.

[0026] In terms of safety, the gripper hole 5 provides a stable and repeatable point of contact, replacing random gripping on smooth barrel walls. The rubber liner maintains a high coefficient of friction even with wet hands, oil, or while wearing gloves, and is less prone to slipping from rain, snow, condensation, and cleaning residue. The rolled edges and chamfered corners eliminate the risk of cuts from sharp edges, preventing tears in gloves or skin during emergency lifts or slope corrections. Furthermore, the fixed grip height allows for more predictable center-of-gravity control during lifting and walking, reducing swaying and tipping caused by shifting center of gravity.

[0027] In terms of efficiency and process standardization, the hand gripper hole 5 "templates" manual handling actions: personnel do not need to find the force-bearing position or temporarily add straps, the grip-lift-release action path is fixed, and the loading and unloading rhythm is more stable; the circumferential arrangement of multiple holes makes it easy for two people to cooperate symmetrically to bear force, and also makes it easy for a single person to complete short-distance movement with slight assistance from the knee / hip, reducing the dependence on forklifts, slings and other auxiliary tools, and improving the flexibility of transportation and site adaptability.

[0028] In terms of durability and maintenance, the five sections of the gripper hole are supported by a rigid ring frame consisting of a bottom ring 401 and a vertical rod 402. The gripping force is not directly applied to the thin barrel wall, avoiding local bulging and screw deformation, and indirectly improving the coaxiality of the opening edge and the sealing life. The rolled edge structure of the hole improves the local bending and tear resistance. The rubber gasket is a replaceable part that can be quickly replaced according to wear, maintaining long-term anti-slip performance. A drainage / cleaning groove can be designed between the gasket and the bottom of the hole to prevent water accumulation and dirt trapping after rinsing, meeting the hygiene requirements of food and pharmaceutical scenarios.

[0029] In terms of multi-scenario adaptability, the 5-point gripper can be used for low-level horizontal handling and also facilitates fine-tuning of posture when placed at an angle, crossing steps, or loading / unloading goods onto or off vehicles. When used in conjunction with the 404 lifting point on the top ring, manual positioning and guidance are handled by humans, while mechanical lifting is carried out, forming a "human-guided, machine-lifted" division of labor mode, which ensures both safety and improves overall handling efficiency. In summary, the 5-point gripper combines "reliable gripping position" with "optimal path for structural load-bearing," while also taking into account anti-slip, injury prevention, durability, and hygiene, systematically solving the pain points of traditional manual handling of metal drums: "difficult to grip, easy to slip, easy to get injured, and low efficiency."

[0030] In this embodiment, the top ring 404 is provided with several lifting rings 6. The lifting rings 6 on the top ring 404 provide a stable and predictable multi-point lifting and fixing interface for the barrel. During manual handling, they can be used with slings or simple lever hoists to form a closed force path, so the operator no longer needs to directly grasp the smooth barrel wall to complete the lifting and repositioning, reducing the risk of slipping and falling when operating with wet hands, oil, or gloves. During mechanical handling, the lifting rings 6 can be quickly hooked onto crane hooks, mobile gantry cranes, or forklifts. The force line runs through the center of gravity of the barrel, resulting in a stable lifting posture and small swing amplitude. Especially after filling with liquid, when the center of gravity shifts upward and the total weight increases significantly, it can still maintain vertical lifting and landing and stable positioning, avoiding secondary damage such as barrel wall denting, weld shearing, and seal ring crushing caused by tipping.

[0031] In terms of ergonomics and labor intensity control, the combination of the top ring 404 lifting point and the bottom ring 401 hand gripping hole 5 transforms traditional high-load actions such as bending over to lift and friction sliding into a standard upright grab-lift-release action. The spatial position of the lifting ring 6 is optimized around the center of gravity of the bucket, so that the lines of action of the lifting force and gravity coincide as much as possible, significantly reducing the additional torque on the wrist and arm; the hand gripping hole 5 at the bottom ring 401 provides low-position guidance and posture fine-tuning fulcrum, allowing the operator to complete short-distance displacement and angle correction without changing the neutral position of the spine, reducing fatigue during long-term continuous operation and making the average processing rhythm of the team more stable. For heavy-duty turnover scenarios such as food and chemical industries, loading and unloading can be completed by a single person, greatly reducing the reliance on temporary personnel and temporary auxiliary tools.

[0032] In terms of bulk transportation and in-situ fixation, the lifting ring 6 combines limiting and connecting functions. It can be quickly strung together in rows on truck beds, containers, or automated storage and retrieval systems using ropes, buckles, and soft straps, giving each container a clear lateral and longitudinal limiting point, making it less likely to roll or collide with each other when the vehicle turns, decelerates, or when the road surface vibrates. Compared with traditional methods that rely on wooden wedges, rubber blocks, or temporary binding, this structure modularizes and standardizes the loading and unloading process, with clear loading and unloading paths and rapid site clearance, reducing the consumption of binding materials and the time required for secondary on-site cleanup. It is suitable for high-frequency turnover and large-scale distribution systems.

[0033] In terms of equipment compatibility and functional extension, the lifting ring 6 is compatible with various material handling equipment such as electric hoists, gantry cranes, rail trolleys, and robotic arm grippers, making it easy to integrate into automated or semi-automated production lines. During warehouse stacking, the lifting ring 6 can also act as a guide contact point for the upper-level barrels, forming a "self-guided positioning" with the circumferential rigidity of the handling frame 4, reducing the risk of repeated repositioning and impacts during high-level shelving. Combined with the surface-line-point force path of the encircling handling frame 4, the outer frame preferentially absorbs and disperses handling and impact energy, maintains the roundness of the barrel wall and the coaxiality of the opening, and ensures long-term stable engagement of the threads and sealing rings. This significantly improves the reliability and economy of the entire chain from single-barrel operations to batch logistics while ensuring sealing and structural lifespan. In summary, this structure, by integrating the human-machine operation point with the structural load-bearing point, systematically solves the pain points of traditional barrels—"difficult to grip, easy to tip over, laborious handling, and cumbersome fixing"—achieving comprehensive optimization of safety, efficiency, stability, and cost.
