Description

Technical Field

[0001] The utility model relates to the field of barrels, in particular to a barrel that is easy to stack. Background Art

[0002] In existing barrel designs, there are various ways to connect the lid and barrel body, with common designs using snap-fit, threaded, or buckled connections. However, when stacked multiple times, direct contact between the lid and barrel body, especially when barrels are stacked without lids, can easily damage patterns or decorations on the barrel walls. Patterns, trademarks, or decorative designs on barrel walls are typically affixed via spraying, stickers, or other methods. While these patterns have a certain degree of wear resistance, repeated stacking or contact can still cause scratches or wear, affecting the product's appearance and market image.

[0003] Specifically, when multiple barrels are stacked, especially when lids are not installed, the current barrel design lacks effective protective measures. Friction between the barrel wall and the bottom or other barrels can cause partial or complete scraping of the pattern on the barrel wall. Scratched or damaged patterns not only diminish the barrel's appearance but also potentially affect the brand's image. This is particularly true for commercial applications or high-end markets, where a damaged appearance often translates to a decrease in the product's added value and market competitiveness.

[0004] Furthermore, because traditional lid designs fail to consider a close fit and protective measures between the lid and the barrel, stacking the barrels results in unstable contact between the lid and the barrel, which can easily cause mechanical damage to the pattern. Existing lid designs lack a structure that adapts to different stacking methods, and they cannot effectively prevent friction or collisions between the lid and the barrel during transportation and storage, which can lead to scratches on the barrel pattern. Therefore, how to solve the problem of damage to the barrel wall pattern when stacking barrels without affecting the lid's functionality has become a major challenge in current barrel design.

[0042] The following will be combined with the drawings in this application to clearly and completely describe the technical solutions in this application. Obviously, the embodiments described are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0043] The utility model discloses a barrel that is easy to stack and is used for protecting the outer side of the barrel wall, which will be described in detail below with reference to the accompanying drawings.

[0044] See also Figures 1 to 14 , an embodiment of the bucket provided by this application includes:

[0045] Bucket cover 01, bucket body 02, bucket mouth 03 and bucket bottom 04;

[0046] The barrel bottom 04, the barrel mouth 03 and the barrel body 02 are integrally formed; the barrel mouth 03 is set at the top of the barrel body 02, and the barrel bottom 04 is set at the bottom of the barrel body 02; the barrel cover 01 is used to cover the barrel mouth 03;

[0047] A first limiting portion is provided on the top of the barrel cover 01, and a second limiting portion matching the first limiting portion is provided on the lower portion of the barrel bottom 04; when the first limiting portion and the second limiting portion cooperate, the barrel cover 01 and the barrel bottom 04 are limited in the horizontal direction;

[0048] The upper part of the barrel body 02 is provided with a skirt 05 which surrounds the barrel body 02, and the skirt 05 is provided with a plurality of third limiting parts which are symmetrically distributed around the skirt 05; the barrel mouth 03 is provided with a fourth limiting part which matches the third limiting part.

[0049] In this embodiment, the basic structure of the barrel consists of a barrel cover 01, a barrel body 02, a barrel mouth 03 and a barrel bottom 04, wherein the barrel bottom 04, the barrel mouth 03 and the barrel body 02 are integrally formed. The barrel mouth 03 is located at the top of the barrel body 02, and the barrel bottom 04 is at the bottom of the barrel body 02. This one-piece design reduces the connection links between the components, improves the stability and strength of the structure, and reduces the risk of leakage. The barrel cover 01 is used to close the barrel mouth 03, which plays a role in sealing and protecting the items in the barrel. It should be noted that the shape of the barrel body 02 can be designed according to actual conditions. It can be designed to be round, square, or other shapes. This application does not limit this. The shape of the barrel cover 01 and the barrel bottom 04 depends on the shape of the barrel body 02.

[0050] A first stopper is located at the top of the lid 01, and a second stopper is located below the bottom 04. The cooperation between the lid 01 and the bottom 04 is crucial, ensuring that the lid 01 does not shift horizontally. When the lid 01 is placed on the mouth 03, the first and second stoppers work closely together to restrict horizontal movement of the lid 01 and bottom 04. This not only prevents the lid 01 from accidentally falling off during transport or tilting, but also enhances the seal, preventing leakage of the contents.

[0051] The upper portion of the barrel body 02 is designed with a skirt 05 that surrounds the barrel body 02. Multiple third limiting parts are evenly arranged within the skirt 05, and these limiting parts are symmetrically distributed. The barrel mouth 03 is provided with a matching fourth limiting part. The cooperation of the third and fourth limiting parts further enhances the stability between the barrel lid 01 and the barrel body 02. Through this cooperation, the barrel lid 01 receives additional stable support in the vertical direction, preventing the barrel lid 01 from shifting or falling due to gravity or external forces. In addition, this design allows the barrel lid 01 to distribute pressure more evenly, further improving the sealing effect of the barrel lid 01.

[0052] The skirt 05 provides additional mechanical support, ensuring a tight fit between the lid 01 and the barrel body 02. The third stopper within the skirt 05, when engaged with the fourth stopper on the barrel mouth 03, creates an effective "locking" effect, making the lid 01 more secure during use and less likely to loosen or fall off. The design of the skirt 05 also evenly distributes external pressure or squeezing forces on the lid 01, reducing the risk of damage from localized overload.

[0053] Through the cooperation of the first limiting part and the second limiting part, and the third limiting part and the fourth limiting part, the stability of the barrel cover 01 and the barrel bottom 04 is greatly improved. The barrel cover 01 is not only limited in the horizontal direction, but also stably supported in the vertical direction. During transportation, handling or storage, especially during transportation, if there is nothing in the barrel, there is no need to cover the barrel cover 01 on the barrel body 02. At this time, multiple barrels can be stacked together. For two adjacent barrels, the upper barrel is inserted into the lower barrel. The third limiting part of the upper barrel cooperates with the fourth limiting part of the lower barrel, so that the mutual movement between the two barrels is restricted, which can reduce damage to the outer barrel wall, thereby protecting the outer barrel wall. During transportation, handling or storage, especially during transportation, if items are placed in the barrel, in order to protect the items in the barrel, the barrel cover 01 needs to be covered on the barrel body 02. At this time, multiple barrels can still be stacked together. For two adjacent barrels above and below, the second limiting portion of the upper barrel cooperates with the first limiting portion of the lower barrel to limit the mutual movement of the two barrels in the horizontal direction, so that the multiple barrels stacked together are not prone to tipping over.

[0054] Furthermore, a handle for conveniently lifting the bucket can be provided at the skirt 05 or the bucket mouth 03.

[0055] In practical applications, the first limiting portion and the second limiting portion may include various configurations, which are described below:

[0056] See also Figure 2 An embodiment of the first composition of the first limiting portion and the second limiting portion includes:

[0057] The first limiting portion is arranged on the inner side of the top of the barrel cover 01 , and the first limiting portion includes at least two limiting grooves 06 , and the second limiting portion includes at least two limiting protrusions matching the limiting grooves 06 .

[0058] The first stopper is located on the inside of the top of the lid 01, rather than on the outside or elsewhere. This design ensures that the stopper mates directly with the inside of the lid 01, making the stopper more stable and secure. The first stopper includes at least two stopper slots 06, the position and number of which are designed to ensure precise engagement with the second stopper on the bottom 04. The provision of stopper slots 06 ensures a more precise fit between the lid 01 and the bottom 04, preventing loosening or misalignment.

[0059] The second stopper, located below the bottom 04, comprises at least two stopper protrusions that mate with the stopper grooves 06 in the first stopper. These stopper protrusions mate with the stopper grooves 06 on the inner top of the lid 01, creating a physical constraint that allows the lid 01 to be positioned more precisely and stably on the bottom 04. The number and placement of these stopper protrusions ensures a more secure fit between the lid 01 and the bottom 04, enhancing the securing effect between the lid 01 and the bottom 04.

[0060] The main advantage of this design is that the cooperation between the limiting groove 06 and the limiting protrusion provides a more precise limiting effect. The matching of each limiting groove 06 and the limiting protrusion ensures that the barrel cover 01 and the barrel bottom 04 fit very tightly in the horizontal direction and are not prone to loosening or misalignment. The structural form of the limiting groove 06 and the limiting protrusion not only enhances the stability of the fit, but also avoids the concentrated pressure caused by a single limiting point, thereby improving the load-bearing capacity and durability of the entire system. The improved design effectively prevents the barrel cover 01 from shifting or falling off during use, improves the sealing and structural stability of the barrel, and ensures the safe storage of items in the barrel.

[0061] See also Figures 3 and 4 An embodiment of the second composition of the first limiting portion and the second limiting portion includes:

[0062] A groove is provided on the edge of the barrel cover 01 , and the first limiting portion includes a first reinforcing rib 07 surrounding the groove; the second limiting portion includes a second reinforcing rib 08 provided on the inner edge of the barrel bottom 04 ; the first reinforcing rib 07 matches the second reinforcing rib 08 .

[0063] The edge of lid 01 is designed with a groove, which not only enhances the appearance of lid 01 but also increases the mechanical strength of the edge. The shape and depth of the groove effectively mate with the second reinforcing rib 08 of bottom 04, improving the fit between lid 01 and bottom 04.

[0064] The first retaining portion includes a first reinforcing rib (07) surrounding the groove. This rib further strengthens the edge of the lid (01) and provides additional support. The structural design of the first reinforcing rib (07) stabilizes the lid (01) against external forces, preventing deformation or damage. It also closely mates with the second reinforcing rib (08) of the second retaining portion, further strengthening the securing force between the lid (01) and the bottom (04).

[0065] The second stopper consists of a second reinforcing rib 08 positioned along the inner edge of the bottom 04. The design of the second reinforcing rib 08 matches the first reinforcing rib 07 surrounding the groove on the lid 01. This coordination provides a more secure connection between the lid 01 and the bottom 04, preventing loosening during use. The second reinforcing rib 08 not only enhances the structural strength of the bottom 04 but also, by working in conjunction with the first reinforcing rib 07, improves the stability of the connection between the lid 01 and the bottom 04.

[0066] By adding grooves and reinforcing ribs, the limiting effect between the barrel cover 01 and the barrel bottom 04 has been significantly enhanced. The number and shape of the first reinforcing rib 07 and the second reinforcing rib 08 match. The cooperation of the first reinforcing rib 07 and the second reinforcing rib 08 effectively improves the positioning accuracy of the barrel cover 01 and the barrel bottom 04, preventing the barrel cover 01 from loosening or misalignment during use. The design of grooves and reinforcing ribs makes the connection between the edge of the barrel cover 01 and the edge of the barrel bottom 04 more secure, while also increasing the bearing capacity and durability of the overall structure. When subjected to external force or pressure, this structural design can evenly distribute stress, reduce local stress concentration, and improve the service life and stability of the barrel. Overall, this structure improves the sealing, stability and pressure resistance of the barrel, ensuring the safety and reliability of the barrel during use.

[0067] In practical applications, the third limiting portion and the fourth limiting portion may include various components, which are described below respectively:

[0068] See also Figure 5 An embodiment of the first composition of the third limiting portion and the fourth limiting portion includes:

[0069] The third limiting portion includes ordinary reinforcing ribs 09 and special reinforcing ribs 10, with the special reinforcing ribs 10 being longer than the ordinary reinforcing ribs 09. The fourth limiting portion is a retaining groove 11, which matches the special reinforcing ribs 10. The retaining groove 11 is located outside the barrel mouth 03; the top of the barrel mouth 03 is used to support the ordinary reinforcing ribs 09.

[0070] The third limiting portion is composed of ordinary reinforcing ribs 09 and special reinforcing ribs 10, with the special reinforcing ribs 10 being longer than the ordinary ribs 09. The ordinary reinforcing ribs 09 provide basic structural support and stability, while the special reinforcing ribs 10, through their longer design, enhance the support capacity of the barrel 02 under load, better dispersing external forces and improving overall stability.

[0071] The fourth limiting element utilizes a retaining groove 11, which, in conjunction with the special reinforcing rib 10, plays a crucial role in limiting the position. The retaining groove 11 securely engages the special reinforcing rib 10, ensuring a tight horizontal fit between the lid 01 and the body 02, preventing the lid 01 from loosening or shifting. The length and position of the special reinforcing rib 10 precisely match the retaining groove 11, ensuring a more secure and reliable fit between the lid 01 and the body 02.

[0072] The latching groove 11 is formed on the outside of the barrel mouth 03. This design helps ensure that the barrel cover 01 can be smoothly fixed to the barrel body 02 during installation. The position of the latching groove 11 makes the process of latching the special reinforcement rib 10 smoother, avoiding improper fit caused by the contents of the barrel or external interference.

[0073] The top of the bunghole 03 is specifically designed to support the standard ribs 09. This design ensures that the standard ribs 09 are effectively supported during installation, enhancing the overall structural strength of the bunghole 02. The support provided by the standard ribs 09 ensures a more stable connection between the lid 01 and the bunghole 02, preventing it from loosening or becoming damaged due to external forces or prolonged use.

[0074] This design strengthens the connection stability between the lid 01 and the barrel body 02 through the cooperation of special reinforcing ribs 10 and ordinary reinforcing ribs 09. The cooperation between the special reinforcing ribs 10 and the locking grooves 11 ensures that the lid 01 and the barrel body 02 are firmly locked in the horizontal direction, preventing the lid 01 from loosening or misaligning. The locking grooves 11 are located on the outside of the barrel mouth 03, effectively preventing the items in the barrel from interfering with the fitting process and ensuring a precise fit between the lid 01 and the barrel body 02. The ordinary reinforcing ribs 09 enhance the overall load-bearing capacity of the barrel body 02 by supporting the top of the barrel mouth 03, providing additional stability, allowing the entire structure to evenly distribute pressure when subjected to force, and reducing damage caused by excessive local force. Overall, this design not only improves the sealing, stability and durability of the lid 01 and the barrel body 02, but also enhances the barrel's pressure resistance, ensuring reliability and safety during long-term use.

[0075] See also Figure 6 An embodiment of the second composition of the third limiting portion and the fourth limiting portion includes:

[0076] The third limiting portion includes ordinary reinforcing ribs 09 and special reinforcing ribs 10, with the special reinforcing ribs 10 being longer than the ordinary reinforcing ribs 09. The fourth limiting portion is a retaining groove 11, which matches the special reinforcing ribs 10. A support portion 12 is provided at the bottom of the barrel mouth 03, and the retaining groove 11 is formed on the support portion 12, which is used to support the ordinary reinforcing ribs 09.

[0077] The third limiting portion includes regular reinforcing ribs 09 and special reinforcing ribs 10. Special reinforcing ribs 10 are longer than regular ribs 09, providing greater support and stability. Regular ribs 09 primarily provide general support and stability, while special ribs 10, with their longer length, enhance support under load, preventing deformation of the lid 01 or body 02 due to external forces.

[0078] The fourth retaining feature is designed as a retaining groove 11, which mates with a special reinforcing rib 10. When lid 01 is installed, retaining groove 11, in conjunction with special reinforcing rib 10, securely fastens lid 01 to body 02, preventing it from loosening or misaligning. Retaining groove 11 ensures a stable horizontal connection between lid 01 and body 02.

[0079] A support portion 12 is provided at the bottom of the barrel opening 03 to support the conventional reinforcement ribs 09 on the barrel lid 01. The design of the support portion 12 strengthens the fit between the barrel lid 01 and the barrel body 02, ensuring that the conventional reinforcement ribs 09 can evenly distribute pressure when subjected to force, thus preventing localized deformation or damage.

[0080] The retaining groove 11 is located on a support portion 12, specifically on the inner bottom of the barrel opening 03. This design allows the retaining groove 11 to precisely engage with the special reinforcement rib 10, ensuring a secure connection between the lid 01 and the barrel body 02. The presence of the support portion 12 further enhances the precision of the retaining groove 11, ensuring that it can smoothly engage the special reinforcement rib 10 during installation, thereby enhancing the stability of the overall structure.

[0081] This design greatly improves the stability between the barrel cover 01 and the barrel body 02 by matching ordinary reinforcing ribs 09 with special reinforcing ribs 10. The design of the special reinforcing ribs 10 being longer than the ordinary reinforcing ribs 09 provides additional support, especially when subjected to external forces, it can effectively disperse stress and enhance the durability of the structure. The combination of the positioning grooves 11 and the special reinforcing ribs 10 ensures the stability of the barrel cover 01 in the horizontal direction, preventing the barrel cover 01 from loosening or shifting. The design of the support portion 12 provides additional support for the ordinary reinforcing ribs 09, ensuring that the shape of the barrel cover 01 is not easily deformed during use and enhancing the matching accuracy. Overall, this design effectively improves the sealing, stability and durability between the barrel cover 01 and the barrel body 02, enhances the pressure resistance of the barrel, and ensures reliability during long-term use.

[0082] For further information, see Figure 7 In the first or second composition of the third limiting portion and the fourth limiting portion, a symmetrically distributed hand rest 13 is provided on the skirt 05, and no ordinary reinforcing ribs 09 and special reinforcing ribs 10 are provided at the hand rest 13.

[0083] Symmetrically positioned hand rests 13 are provided on skirt 05. These hand rests make the bucket easier to carry and move, allowing users to lift and carry it more comfortably. The symmetrical placement of the hand rests 13 ensures even weight distribution when lifting the bucket, reducing excessive force on one side and improving stability and comfort during handling. It should be noted that there must be at least two hand rests.

[0084] The palm rest 13 is intentionally devoid of standard reinforcement ribs 09 and special reinforcement ribs 10. This design ensures comfort and convenience in the palm rest 13 area. The absence of reinforcement ribs in the palm rest 13 avoids affecting its structure and shape, ensuring comfortable handling. It also prevents stiffening of the palm rest 13 area, maintaining grip flexibility.

[0085] This design makes the bucket easier to carry and ergonomically ergonomic by providing symmetrically distributed hand rests 13 on the skirt 05, which reduces the burden on the hands during handling. The absence of ordinary reinforcing ribs 09 and special reinforcing ribs 10 avoids the creation of overly rigid structures or protruding components on the hand rest 13, making the hand rest 13 smoother and more comfortable to carry. At the same time, the symmetrically distributed hand rests 13 effectively balance the weight distribution of the bucket, improve the stability of the user during use, and reduce the discomfort caused by uneven force on the hand rest 13. Overall, this design improves the convenience and comfort of the bucket, making it suitable for a wider range of usage scenarios, while also ensuring the practicality and stability of the bucket in daily use.

[0086] Furthermore, the palm rest 13 is provided with an outward protrusion.

[0087] The hand rest 13 features an outward protrusion. This protrusion not only enhances the grip of the hand rest 13 but also further improves stability and comfort during use. The outward protrusion helps the fingers stay firmly in place on the hand rest 13, preventing slippage or loss of grip during handling. The protrusion makes the hand rest 13 more ergonomic, improving comfort and safety during lifting.

[0088] The outwardly protruding design of the hand rest 13 creates a better connection with the barrel body 02. The shape and position of the protrusion ensure a stable feeling when lifting the barrel and reduce slippage between the hand and the barrel body 02. This not only increases the firmness of the grip, but also reduces the pressure on the hand, making it easier to carry.

[0089] The outward protrusions enhance the grip of the hand rest 13, allowing the user to hold the bucket more securely when carrying it, preventing slippage or a loose grip. The shape and placement of the protrusions improve lifting comfort and safety, especially when carrying heavy or large buckets. This design effectively distributes pressure on the hand and reduces discomfort. Overall, the outward protrusions enhance the user experience of the bucket, not only increasing grip stability and comfort, but also making carrying the bucket safer and more convenient.

[0090] See also Figures 8 and 9 An embodiment of the third configuration of the third limiting portion and the fourth limiting portion includes:

[0091] The third limiting part is a locking block 14; the fourth limiting part is a locking protrusion 15 arranged on the outer side of the top of the barrel mouth 03, and a groove matching the locking block 14 is opened on the top of the locking protrusion 15; or, the fourth limiting part is an opening 16 opened on the inner side of the top of the barrel mouth 03 and matching the locking block 14.

[0092] The third stopper is a retaining block 14. Retaining block 14 provides a reliable physical stop for engagement with lid 01 or body 02, ensuring a stable connection between lid 01 and body 02.
