Description

Technical Field

[0001] The utility model relates to a storage container, in particular to a container and a box cover thereof. Background Art

[0002] Medium-sized composite bulk containers are mostly used in the field of food and chemical liquid packaging. In the process of circulation from raw material manufacturers to downstream processors, this type of container can store and protect the safety of goods. Generally, foldable medium-sized composite bulk containers are called IBCs, and most non-foldable medium-sized composite bulk containers appear in the form of ton barrels or ton boxes. In terms of the box structure, foldable containers usually include two pairs of foldable side panels, which are hinged to the base and the box cover is buckled on the side panels. The box cover needs to be opened and closed frequently, so a simple unlockable locking structure and side panel connection are mostly used. Ton barrels are generally steel frames with an integrated blow-molded inner shell. In comparison, foldable containers have better return trips and space occupancy when idle, higher economic benefits, and the integrated structure of ton barrels has higher reliability.

[0003] Generally, the lid of an IBC has a single-walled structure, which can buffer the impact of the liquid on the lid and then on the body of the box when the liquid in the box rises and falls due to bumps. However, due to the creep characteristics of plastics, the lid of a single-layer structure will sag and collapse over time. Although the ribs can improve this problem, the huge volume of the lid and the support method of the middle part being suspended make the sag problem difficult to solve in a single-layer lid structure.

[0004] In addition, it should be noted that in order to make up for the gap in box strength with ton barrels, an IBC box cover on the market is connected to the side panels through eight locking structures, and two locking structures are provided on the top of each side panel. This design of the box cover can bring good connection strength to the entire IBC box, but the concave phenomenon of the box cover will cause some of the locks to become stuck, causing trouble in operation.

[0005] Another idea is to make the box cover into a double-walled structure, which is produced by blow molding, double-layer blister molding, or welding. The double-walled box cover has a better rigidity advantage, and there are also cases of its use on existing IBC products. Since the rigidity of the double-walled box cover is greatly improved, its creep sag problem is improved, but the problem is that excessive rigidity means that the buffering ability of the double-walled box cover to resist impact is reduced. When the liquid in the box fluctuates violently, the impact force is transmitted to the box cover and then to the locking structure. At this time, the impact force on the locking structure is greatly increased compared to the single-layer box cover, which is easy to cause damage to the locking structure.

[0006] It is particularly important to note that the weight of a single-layer cover is less than 7KG, while the weight of a double-layer cover is nearly 10KG. The greater weight also brings inconvenience to operation. Utility Model Content

[0056] The utility model relates to a container 100 and a box cover 2 thereof. Figure 1 and Figure 2 In the illustrated embodiment, the container 100 is a medium-sized composite bulk container 100, which is mostly used in the field of food and chemical liquid packaging. This container 100 can store and protect the safety of goods well during the circulation process from raw material manufacturers to downstream processors, and is referred to as IBC.

[0057] The container 100 includes a box body 1 and the above-mentioned box cover 2, wherein the box body 1 includes two pairs of side panels and a base, the two pairs of side panels are connected end to end and the bottom ends are connected to the base, the two pairs of side panels are respectively defined as a first pair of side panels 11 and a second pair of side panels 12, the first pair of side panels 11 and the second pair of side panels 12 can be folded in sequence on the top surface of the base to reduce the storage space occupied by the container 100 when not in use, thereby reducing the turnover and storage costs of the product.

[0058] The box cover 2 includes a top cover 21 and a bottom cover 22, wherein the top cover 21 includes a top plate 211, a side guard 212 and a welding rib 213, wherein the top plate 211 can cover the opening of the box body 1 and is provided with a first area 214 and a second area 215, wherein the first area 214 includes at least two parts with different strengths. The side guard 212 is annular and connected to the outer periphery of the top plate 211, and the side guard 212 can be detachably connected to the box body 1. The welding rib 213 is connected to the second area 215 to strengthen the strength of the second area 215. The bottom cover 22 is connected to the bottom surface of the top cover 21, and specifically, the bottom cover 22 and the top cover 21 can be welded by a hot plate or vibration friction welding process.

[0059] The box cover 2 of the utility model is a double-layer structure, which has a better rigidity advantage. Moreover, the first area 214 of the top cover 21 includes at least two parts with different strengths, which can improve the rigidity of the top cover 21 and make it have a certain creep performance. When the liquid in the box fluctuates violently, the impact force is transmitted to the box cover 2, and the box cover 2 can withstand a certain impact force and has a buffering ability to resist the impact. It has good reliability and buffering ability. Moreover, the parts with different strengths have different thicknesses, which can reduce the weight of the box cover 2 to a certain extent, making it moderate in weight. Combined with the unique box cover 2 locking structure technology, it can provide convenience in the operation of the box cover 2.

[0060] The box cover 2 can be connected to the first pair of side plates 11 of the two pairs of side plates through a locking mechanism 3, and the locking mechanism 3 includes a locking member, a driving member, a reset member, a lock hole 31 formed on the outer side of the first pair of side plates 11, and a groove formed on the box cover 2, wherein one end of the locking member is installed in the groove, and the other end of the locking member is provided with a lock head 32, and the lock head 32 passes through the edge guard 212 and can extend into the lock hole 31 in a direction perpendicular to the first pair of side plates 11, thereby locking the upper cover on the side plate, the driving member is installed in the groove and used to drive the locking member to unlock, and the reset member is installed in the groove and used to reset the driving member after unlocking. The lock hole 31 is a groove perpendicular to the surface of the side plate. When the box cover 2 is covered on the installation box body 1, the lock head 32 just extends into the lock hole 31, thereby locking the box cover 2 on the first pair of side plates 11. The specific implementation of the locking mechanism 3 can refer to patent CN104590787B, which will not be repeated.

[0061] exist Figure 5-6 In the illustrated embodiment, the first area 214 is located in the middle of the top cover 21, and the second area 215 is disposed around the first area 214 and the outer periphery of the second area 215 is spaced from the edge guard 212. After the box cover 2 is covered on the box body 1, the space between the second area 215 and the edge guard can accommodate the top ends of the first pair of side panels 11 and the second pair of side panels 12.

[0062] The bottom cover 22 is connected to the bottom surface of the second area 215 through a partial welding rib 213. In addition, the second area 215 is provided with a welding rib 213, which can also make the strength of the second area 215 greater than the strength of the first area 214. In practice, the second area 215 and the bottom cover 22 can enhance the rigidity of the box body 1 after being combined to prevent the box body 1 from collapsing during use. The first area 214 is composed of parts with different strengths, which can make the box body 1 have a certain creep performance, can replace the impact force of the liquid in the box body 1, and prevent the impact force from being transmitted to the locking mechanism 3.

[0063] As a preferred solution, the bottom cover 22 is provided with an air avoidance area 222, which penetrates the bottom cover 22 and is aligned with the first area 214, that is, the overall shape of the bottom cover 22 is roughly similar to or the same as the shape of the second area 215, that is, the bottom cover 22 covers the second area 215 and avoids the first area 214. The strength of the middle of the box cover 2 is supported by the second area 215 of the top cover 21 and the bottom cover 22, and the first area 214 is composed of parts with different strengths, which can make the middle part of the box cover 2 have a certain creep performance. When the liquid in the box body 1 fluctuates violently, it can directly impact the first area 214 of the top cover 21, and the first area 214 can buffer the impact force of the liquid. After the bottom cover 22 and the second area 215 of the top cover 21 are welded, the rigidity of the second area 215 can be made greater, further preventing the box cover 2 from collapsing.

[0064] The air avoidance area 222 can also effectively reduce the weight of the box cover 2, which is about 1.5KG lighter than the weight of the overall double-layer box cover 2 structure, and is more labor-friendly to operators.

[0065] In addition, Figure 6 In the illustrated embodiment, the first region 214 includes two parts with different strengths, namely a first part 216 and a second part 217. The first part 216 is composed of a plurality of spaced weak areas, the thickness of which is small, so that the strength of the weak area is small. The second part 217 is arranged between the plurality of weak areas, that is, the second part 217 separates the plurality of weak areas. The thickness of the second part 217 is greater than the thickness of the weak area, so the strength of the second part 217 is greater than the strength of the weak area. The second part 217 and the first part 216 are cross-combined to form a first region 214 with different thicknesses and strengths, so that the first region 214 can have a certain rigidity and creep performance, which can resist the impact force of the liquid in the box body 1 and prevent the first region 214 from collapsing as a whole.

[0066] exist Figure 6 In the embodiment of the present invention, the first part 216 includes four weak areas, and the second part 217 is a cross-shaped structure and is interspersed between the four weak areas. The top plate 211 is a rectangular plate, and the first part 216 and the second part 217 are symmetrically arranged relative to the center of the top plate 211. It should be understood that in other embodiments, the multiple weak areas can also be arranged in other ways, that is, the multiple weak areas can also be arranged in a disordered manner, and are not limited to Figure 6 The second portion 217 does not need to be arranged in a structure symmetrically arranged relative to the center of the top plate 211, and the present invention does not limit the specific shapes of the first portion 216 and the second portion 217.

[0067] As a preferred solution, the thickness range H1 of the weak area is 3 mm to 4 mm, such as 3 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, 3.5 mm, 3.6 mm, 3.7 mm, 3.8 mm, 3.9 mm and 3 mm, etc. The thickness range H2 of the second portion 217 is 5 mm to 6 mm, which may be selected but not limited to 5 mm, 5.1 mm, 5.2 mm, 5.3 mm, 5.4 mm, 5.5 mm, 5.6 mm, 5.7 mm, 5.8 mm, 5.9 mm and 6 mm, etc.

[0068] In addition, Figure 6In the illustrated embodiment, among the plurality of welding ribs 213, a portion of the welding ribs 213 extends along the circumference of the top plate 211 to form a ring shape, and another portion extends radially and is arranged at intervals along the circumference of the top plate 211. The portion of the welding ribs 213 and the welding ribs 213 extending along the circumference cross to form a network structure, which can enhance the strength of the second region 215. The circumference of the top plate 211 is the direction along the outer periphery of the first region 214, and the radial direction of the top plate 211 is the radial direction with the center of the top plate 211 as the center of the circle.

[0069] The bottom cover 22 includes a bottom plate 221 and two pairs of folded edges. The bottom plate 221 is flat and covers the second area 215. The bottom plate 221 is provided with the above-mentioned escape area 222 for avoiding the first area 214. Among the two pairs of folded edges, one pair of folded edges includes two opposite first folded edges 223, and the other pair of folded edges includes two oppositely arranged second folded edges 224.

[0070] The two first folded edges 223 are connected to two opposite sides of the bottom plate 221 and are respectively disposed opposite to the first pair of side plates 11 . The two second folded edges 224 are connected to the other two opposite sides of the bottom plate 221 and are respectively disposed opposite to the second pair of side plates 12 .

[0071] Specifically, the bottom ends of the two first folded edges 223 extend from opposite sides of the bottom plate 221 to the top plate 211, and the top ends are connected to the top plate 211. The distance between one of the first folded edges 223 and one of the side plates 11 close to it gradually increases from the top end to the bottom end, that is, the slope of the first folded edge 223. The outer side of the first pair of side plates 11 is provided with a lock hole 31, and the lock head 32 is located on a pair of side edges of the edge guard 212 opposite to the first pair of side plates 11. When it is necessary to open the box cover 2, first operate the handle to open the two locking pieces on the same side, and then lift the box cover 2 to an angle approximately as large as 1 / 4. Fig.10 As shown, at this time, the first folded edge 223 is roughly flush with or slightly higher than the top of the side panel. Since the lock head 32 and the lock hole 31 can be moved and disengaged toward the outside of the side panel, continuing to push the box cover 2 toward the right side of Figure 10 will not be blocked by the first folded edge 223 and the lock with the side panel can be released to remove the box cover 2, which is easy to operate.

[0072] The bottom ends of the two second folded edges 224 extend from the other two opposite sides of the bottom plate 221 in a direction perpendicular to the bottom plate 221 to the top plate 211 and are connected to the top plate 211. The second folded edges 224 are steep surfaces and respectively abut against the inner sides of the second pair of side plates 12. When folding, the second pair of side plates 12 are first folded on the base, and then the first pair of side plates 11 are folded on the second pair of side plates 12. When the box body 1 is unfolded and used, the two second folded edges 224 abut against the inner sides of the second pair of side plates 12, which can limit the upper ends of the second pair of side plates 12 from moving inward. Since the conventional way to limit the second pair of side plates 12 from tipping inward is only the side plate lock that is locked with the adjacent first pair of side plates 11, the second folded edges 224 can improve the connection reliability of the entire box. Since the first pair of side panels 11 are supported on the inner side by the second pair of side panels 12 , the box body 1 will not fall inward after being unfolded. Therefore, the first folded edge 223 can be designed to be close to the inner side of the first pair of side panels 11 .

[0073] The container 100 also includes a hanging structure 4, such as Fig.11 As shown, the hanging structure 4 is connected to the bottom surface of the box cover 2 and is staggered with the first area 214. The hanging structure 4 can be used to hang objects, and can be a hook or other forms. The utility model does not limit the specific form of the hanging structure 4. Fig.11 In the illustrated embodiment, the suspension structure 4 is connected to the second region 215 of the top plate 211 and protrudes from the bottom surface of the top plate 211 through the bottom plate 221 .

[0074] Once the conventional single-layer box cover 2 is concave, it will affect the normal operation of the suspension structure 4. The utility model uses a double-layer box cover 2 structure, and the rigidity of the box cover 2 can effectively support the stiffness of its corresponding parts. During use, the first area 214 has a certain creep performance, but the slight concave of the first area 214 will not cause a large collateral effect on the suspension structure 4 of the second area 215.

[0075] The box cover 2 of the utility model is composed of a top cover 21 and a bottom cover 22, and the top cover 21 includes a first area 214 and a second area 215, and the bottom cover 22 covers and is connected to the second area 215 so that the strength of the box cover 2 in the second area 215 is greater than the strength of the first area 214. In addition, the bottom cover 22 in the box body 1 is provided with an air avoidance area 222, and the air avoidance area 222 is used to avoid the first area 214. The box cover 2 can withstand a certain impact force and has a buffering ability to resist impact, has good reliability and buffering ability, and the thickness of the parts with different strengths is different, which can reduce the weight of the box cover 2 to a certain extent, making it moderate in weight, and combined with the unique box cover 2 locking structure technology, it can provide convenience in operation of the box cover 2.
