Description

Technical Field

[0001] This utility model relates to the field of packaging barrel technology, and in particular to a stackable plastic packaging barrel with good sealing effect. Background Technology

[0002] Plastic packaging drums are commonly used containers in industrial storage, logistics transportation, and daily life, widely applied for the storage and transfer of liquids and solids. However, traditional plastic packaging drums present several problems in practical use:

[0003] Traditional packaging barrels often use simple snap-fit ​​or threaded connections between the lid and the barrel body. These connections are prone to leaks due to gaps, especially during bumpy transportation or long-term storage. At the same time, external moisture can easily penetrate the barrel through these gaps, causing the material to become damp and deteriorate, thus affecting storage quality.

[0004] When traditional packaging drums are stacked, the lack of precise positioning and fixing structure between the upper and lower drums makes them prone to tipping over due to shaking or external impact. This not only affects the utilization rate of storage space, but may also cause material damage or safety accidents.

[0005] Based on the shortcomings of traditional plastic packaging drums in sealing and stacking, the development of a plastic packaging drum with good sealing effect and stable stacking function has become an urgent need to improve the safety and convenience of storage and transportation. Utility Model Content

[0006] The purpose of this utility model is to solve the problems in the background art by proposing a stackable plastic packaging bucket with good sealing effect.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a stackable plastic packaging bucket with good sealing effect, including a bucket body and a matching bucket lid. The top periphery of the bucket body is provided with a sealing element for strengthening the sealing of the bucket lid. The bucket lid is placed on the top of the bucket body, and the sealing element seals the connection between the bucket lid and the bucket body to prevent the contents of the bucket body from leaking out and to prevent moisture.

[0008] Preferably, the sealing element includes a sealing ring, which is located at the opening of the barrel body. The sealing ring is a concave hollow ring with an insertion port at the top for the barrel lid to be inserted. The sealing ring is made of plastic. Several No. 2 blocking blocks are connected to one side wall of the sealing ring, and a detachable anti-theft component is provided on the other side wall of the sealing ring. The anti-theft component is used to prevent the barrel lid from being opened a second time after it is connected to the sealing element.

[0009] Preferably, the anti-theft component includes a connecting strip and several No. 1 blocking blocks. The connecting strip is detachably connected to the other side wall of the sealing ring. Several No. 1 blocking blocks are connected to the side of the connecting strip opposite the No. 2 blocking block of the sealing ring. A connecting protrusion is connected between the two ends of the connecting strip. The connecting protrusion is used to disconnect the connection between the connecting strip and the sealing ring. When it is necessary to open the connection between the lid and the body, press the connecting protrusion outward to disconnect the connecting protrusion from the connecting strip at both ends. At this time, the connecting strip drives the No. 1 blocking blocks to detach from the sealing ring, and the No. 2 blocking block on one side of the sealing ring will not be able to prevent the lid from detaching. At this time, the lid can be pulled out and detached from the body.

[0010] Preferably, the first and second blocking blocks are triangular in shape, and the downward-facing side of the first and second blocking blocks has a groove.

[0011] Preferably, the bucket lid includes insert blocks and a limiting ring. The bucket lid is provided with a number of insert blocks corresponding to the first and second blocking blocks. The bucket lid is provided with a limiting ring that is inserted into the edge of the bucket opening to prevent leakage. When the bucket lid is moved to insert the insert blocks into the sealing ring, the insert blocks compress the first and second blocking blocks. After the first and second blocking blocks are compressed, the sealing ring expands and deforms outward. When the insert blocks are fully compressed and extend below the first and second blocking blocks, the limiting ring is locked at the edge of the bucket opening, thus preventing the bucket from leaking.

[0012] Preferably, the insert includes a connecting post connected to the bucket lid and a block-shaped component with an irregular pentagonal cross-section connected to the connecting post. The block-shaped component of the insert is located below and in contact with the first and second blocking blocks, and both of its surfaces are provided with protrusions that engage with the grooves. When the insert is inserted below the first and second blocking blocks, the protrusions on the block-shaped component engage with the grooves on the first and second blocking blocks, thereby improving the stability of the connection.

[0013] Preferably, the barrel lid is provided with a limiting groove, and the barrel body is provided with a reinforcing strip extending from the bottom of the barrel body. The reinforcing strip of one packaging barrel body is inserted into the limiting groove of the barrel lid of another packaging barrel for stacking the two packaging barrels. The reinforcing strip is provided with spokes for reinforcing the strength of the reinforcing strip and increasing the friction with the inner wall of the limiting groove.

[0014] Preferably, the bucket lid is provided with a buckle groove, and the bucket body is provided with a reinforcing member. The reinforcing member includes a soft plastic part connected to the bucket body and a buckle block for inserting into the buckle groove. When the bucket lid is placed on the bucket body, the soft plastic part of the reinforcing member is pulled to cover the edge of the bucket lid, and the buckle block is inserted into the buckle groove to further stabilize the connection between the bucket body and the bucket lid.

[0015] Preferably, the bucket lid is provided with an auxiliary component for storing packaging bags and connecting takeout orders. The auxiliary component includes a storage slot for placing packaging bags, and a protruding tip that passes through the takeout order is provided in the storage slot. A cover plate is interference-fitted on one side of the storage slot. The packaging bag is removed by opening the cover plate, and the takeout order is placed on the protruding tip. The takeout order is pressed and fixed by closing the cover plate.

[0016] In summary:

[0017] The sealing components at the top of the barrel (including the sealing ring, the first blocking block, and the second blocking block), together with the plug and the limiting ring on the lid, form a multi-layer sealing structure: the concave hollow design of the sealing ring, combined with the expansion deformation after the plug is squeezed, can tightly fit the connection between the lid and the barrel body; the interlocking of the plug protrusion and the blocking block groove further enhances the sealing performance, effectively preventing internal items from leaking out, while blocking external moisture from entering, making it suitable for storage scenarios with high moisture-proof requirements.

[0018] The anti-theft components on the sealing ring (connecting strip, connecting protrusion, and No. 1 stop block) achieve anti-theft through an irreversible disconnection structure: the connecting strip can be disconnected from the sealing ring, and after the lid is closed, No. 1 and No. 2 stop blocks lock the plug together. The connecting protrusion must be destroyed to open the lid, preventing the lid from being opened a second time and ensuring the safety of the contents. It is suitable for use in scenarios where it is easy to open, such as transportation or outdoor storage.

[0019] The reinforcing strip at the bottom of the barrel is compatible with the limiting groove of another barrel lid. The spokes on the reinforcing strip not only enhance its own strength but also increase the friction with the inner wall of the limiting groove, making it less likely to tip over when multiple packaging barrels are stacked. This improves the space utilization rate during warehousing and transportation, and facilitates centralized management and handling.

[0020] The insert adopts an irregular pentagonal block structure, which has a large contact area with the triangular block. The interlocking design of the protrusion and groove further enhances the connection strength. Together with the reinforcement parts (soft plastic parts and buckles) to fix the edge of the bucket lid, it effectively prevents the bucket lid from loosening during transportation or stacking and enhances the stability of the overall structure.

[0021] The storage slot in the lid can store packaging bags and other auxiliary items. At the same time, the delivery order is fixed by the protrusion and the cover plate: after the protrusion penetrates the order, the cover plate presses the order tightly with an interference fit, which can prevent the order from falling off or getting wet by rain. It is suitable for transportation scenarios that require the accompanying order and improves the convenience of use.

[0022] The reinforcing strips, sealing rings and other components are made of plastic, which has both elasticity and strength and can withstand multiple stacking and closing operations. The design of the spokes and the irregular structure of the inserts on the reinforcing strips enhances the mechanical properties of key components and extends the service life of the packaging barrel.

[0023] In summary, this stackable plastic packaging bucket performs excellently in terms of sealing, anti-theft, stacking stability, and functional practicality, meeting the needs of various storage and transportation scenarios and possessing high practical value. Attached Figure Description

[0031] Example 1: Refer to Figures 1-4 As shown, this utility model provides a technical solution: a stackable plastic packaging bucket with good sealing effect, including a bucket body 1 and a matching bucket lid 4, characterized in that: a sealing member 3 for strengthening the sealing of the bucket lid 4 is provided on the top periphery of the bucket body 1, the bucket lid 4 is placed on the top of the bucket body 1, and the sealing member 3 seals the connection between the bucket lid 4 and the bucket body 1 to prevent the contents of the bucket body 1 from leaking out and to prevent moisture.

[0032] The sealing element 3 includes a sealing ring 31, which is located at the opening of the barrel body 1. The sealing ring 31 is a concave hollow ring with an insertion port at the top for the barrel lid 4 to be inserted. The sealing ring 31 is made of plastic. Several second-order blocking blocks 33 are connected to one side wall of the sealing ring 31. A detachable anti-theft component is provided on the other side wall of the sealing ring 31. The anti-theft component is used to prevent the barrel lid 4 from being opened a second time after it is connected to the sealing element 3.

[0033] The anti-theft device includes a connecting strip 321 and several first-level blocking blocks 32. The connecting strip 321 can be disconnected from the other side wall of the sealing ring 31. Several first-level blocking blocks 32 are connected to the side of the connecting strip 321 facing the second-level blocking block 33 of the sealing ring 31. A connecting protrusion 322 is connected between the two ends of the connecting strip 321. The connecting protrusion 322 is used to disconnect the connection between the connecting strip 321 and the sealing ring 31. When it is necessary to open the connection between the bucket lid 4 and the bucket body 1, press the connecting protrusion 322 outward with force to disconnect the connecting protrusion 322 from the connecting strip 321 at both ends. At this time, the connecting strip 321 drives the first-level blocking block 32 to disengage from the sealing ring 31. The second-level blocking block 33 on one side of the sealing ring 31 will not be able to prevent the bucket lid 4 from disengaging. At this time, the bucket lid 4 can be pulled out and separated from the bucket body 1.

[0034] The first block 32 and the second block 33 are triangular in shape, and the downward-facing side of the first block 32 and the second block 33 has a groove.

[0035] The lid 4 includes insert blocks 41 and limiting rings 45. The lid 4 is provided with a number of insert blocks 41 corresponding to the first blocking block 32 and the second blocking block 33. The lid 4 is provided with limiting rings 45 that are inserted into the opening edge of the barrel body 1 to prevent leakage. When the lid 4 is moved, the insert blocks 41 are inserted into the sealing ring 31. The insert blocks 41 squeeze the first blocking block 32 and the second blocking block 33. After the first blocking block 32 and the second blocking block 33 are squeezed, the sealing ring 31 expands and deforms outward. When the insert blocks 41 are fully squeezed and inserted under the first blocking block 32 and the second blocking block 33, the limiting ring 45 is stuck at the opening edge of the barrel body 1, which plays the role of preventing leakage of the barrel body 1.

[0036] The insert 41 includes a connecting post connected to the bucket lid 4 and a block-shaped component with an irregular pentagonal cross-section connected to the connecting post. The block-shaped component of the insert 41 is located below the first blocking block 32 and the second blocking block 33, and both sides in contact with them are provided with protrusions that engage with the grooves. When the insert 41 is inserted below the first blocking block 32 and the second blocking block 33, the protrusions on the block-shaped component of the insert 41 engage with the grooves on the first blocking block 32 and the second blocking block 33, thereby improving the stability of the connection.

[0037] The lid 4 is provided with a limiting groove 42, and the body 1 is provided with a reinforcing strip 2 extending from the bottom of the body 1. The reinforcing strip 2 of the body 1 of one packaging barrel is inserted into the limiting groove 42 of the lid 4 of another packaging barrel for stacking the two packaging barrels. The reinforcing strip 2 is provided with spokes to strengthen the reinforcing strip 2 and increase the friction with the inner wall of the limiting groove 42.

[0038] Example 2, based on Example 1, with reference to Figure 5As shown, the bucket lid 4 is provided with a buckle groove 44, and the bucket body 1 is provided with a reinforcing member 11. The reinforcing member 11 includes a soft plastic part connected to the bucket body 1 and a buckle block for inserting into the buckle groove 44. When the bucket lid 4 is placed on the bucket body 1, the soft plastic part of the reinforcing member 11 is pulled to cover the edge of the bucket lid 4, and the buckle block is inserted into the buckle groove 44 to further stabilize the connection between the bucket body 1 and the bucket lid 4.

[0039] Example 3, based on Example 1, with reference to Figure 6 As shown, the bucket lid 4 is provided with auxiliary parts for storing packaging bags and connecting takeout orders. The auxiliary parts include a storage slot 43 for placing packaging bags. A protrusion 431 for passing through the takeout order is provided in the storage slot 43. A cover plate 432 is interference-fitted on one side of the storage slot 43. The packaging bag is removed by opening the cover plate 432 and the takeout order is placed on the protrusion 431. The takeout order is pressed and fixed by closing the cover plate 432.

[0040] Working principle: Stackable plastic packaging drums achieve sealing, anti-theft, and stackability functions through multiple structural designs. The specific working principle is as follows:

[0041] Sealing and Moisture-proof Principle: When the lid 4 is closed, its bottom limiting ring 45 engages with the edge of the opening of the barrel body 1, forming the first sealing barrier to prevent leakage of internal contents. The sealing ring 31 at the top of the barrel body 1 has a concave hollow structure. When the insert block 41 of the lid 4 is inserted, it presses against the first and second blocking blocks 32 on both sides, causing the sealing ring 31 to expand outward and tightly wrap around the insert block 41. The protrusion of the insert block 41 engages with the groove of the blocking block, further enhancing the connection and sealing performance. Combined with the plastic material properties of the sealing ring 31, a moisture-proof effect is achieved.

[0042] Anti-theft principle: The anti-theft component on one side of the sealing ring 31 connects the first blocking block 32 to the sealing ring 31 via the connecting strip 321. After the lid is closed, the first blocking block 32 and the second blocking block 33 lock the insert 41 together. When it needs to be opened, the connecting protrusion 322 must be pressed to break the connecting strip 321; otherwise, the lid 4 cannot be pulled out, preventing secondary opening.

[0043] Stacking principle: The reinforcing strip 2 at the bottom of the barrel 1 can be inserted into the limiting groove 42 of another barrel lid 4. The spokes on the reinforcing strip 2 not only enhance its own strength, but also prevent slippage during stacking by increasing friction.

[0044] Reinforcement function: The reinforcement part 11 of the barrel body 1 covers the edge of the barrel lid with a soft plastic part, and the buckle is inserted into the buckle groove 44 to further stabilize the lid.

[0045] Document securing function: The protrusion 431 in the storage slot 43 can penetrate the takeout order, and the cover plate 432 presses the order firmly after interference fit, achieving waterproof and dustproof securing; the storage slot can also store packaging bags and other auxiliary items.

[0046] Through the synergistic effect of the above structures, the device can ensure both airtightness and moisture protection, as well as theft prevention and convenient stacking, making it suitable for scenarios requiring long-term storage or transportation.

[0047] The connecting components mentioned above are all available on the market. Therefore, the installation and welding between the connecting components are not related to innovation and will not be described in detail. Some components can also be obtained through private customization, so they will not be described in detail either.

[0048] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
