Referring specifically to fig. 1, an epicyclic vessel 100 according to the present invention is shown. The epicyclic vessel 100 comprises a box 200 and stacking rods 300. Specifically, the case 200 includes a bottom plate 210 and two pairs of side plates 220 and 230. Two pairs of side plates 220 and 230 are connected to each other and extend upward from the bottom plate 210, thereby forming an opening through which the case 200 is opened upward. In order to facilitate stacking of the containers 100 on top of one another in the empty state, the side plates 220 and 230 of the box 200 form a cross-sectional profile which increases gradually from the base plate 210 upwards, so that an upper container 100 can be inserted into a lower empty container 100. Specifically, it is possible to provide four side plates all having a certain inclination, and it is also possible to provide only two adjacent side plates or three side plates having a certain inclination. In addition, since such an epicyclic container 100 is generally used for storing fresh food in practice, a plurality of through holes are opened on the side plate of the case 200 to ensure ventilation of the contents.
A pair of stacking bars 300 are provided at upper edges of the pair of side plates 230, respectively. In the illustrated embodiment, the stacking rod 300 is in the form of a slat. In the illustrated embodiment, the stacking bar 300 is made of a thin plate material, and in order to reinforce the strength thereof, a plurality of criss-cross reinforcing ribs are provided on one side thereof. A pair of stacking bars 300 is hinged to the upper edges of the two side plates 230, respectively, and each stacking bar 300 is pivotable between a first position and a second position relative to the upper edge of the corresponding side plate 230. In the first position, the stacking bar 300 extends substantially in the direction of the plane of the opening and spans the upper edges of two adjacent side plates 220; and in the second position, the stacking bar 300 is erected in a substantially vertical direction, thereby avoiding the opening of the case 200.
As shown in fig. 1, two grooves 221 are further formed at an upper edge of each side plate 220, and both ends of the stacking bar 300 are respectively located in the corresponding grooves 221 when the stacking bar 300 is located at the first position. Preferably, the width of the groove 221 in the extending direction of the side plate 220 is reduced as the depth of the groove increases, thereby forming a guide portion for the stacking bar 300 to be inserted into the groove 221, facilitating the stacking bar 300 to be inserted more smoothly. In this state, the upper sides of the pair of stacking bars 300 form a plane on which the upper turnaround container 100 can be placed, so that other turnaround containers 100 can be stacked thereon also when the turnaround containers 100 are filled with goods.
In the preferred embodiment shown in fig. 5 and 6, stacking bar snaps 330 are also provided at both ends of the stacking bar 300, and complementary box snaps 2211 are provided in the groove 221, so that the stacking bar 300 is more securely held in place relative to the side plates 220 when both ends are placed into the groove 221. Specifically, the stacking bar engaging portion 330 is a laterally extending protrusion provided on both sides of a reduced diameter section of the stacking bar 300 having an end portion extending in the longitudinal direction when in the first position, and the box engaging portion 2211 is a recess of the groove 221 on both sides in the extending direction of the side plate 220. It should be understood that the stacking bar engagement portion 330 and the box engagement portion 2211 can be other forms, such as the stacking bar engagement portion 330 being a protrusion on the side of the end of the stacking bar 300 and the box engagement portion 2211 being a recess on the side of the groove 221.
Complementary snap features are provided on the upper edges of the pair of side plates 230 and the lower edge of the stacking lever 300 when in the second position. Specifically, as shown in fig. 2, the side plate 230 is provided at an upper edge thereof with a stopper groove 231 extending in the extending direction of the side plate 230, and the stacking bar 300 is correspondingly provided at a lower edge thereof with a stopper protrusion 310 extending along a lower edge thereof in the second position, so that the stopper protrusion 310 can be caught in the stopper groove 231 when the stacking bar 300 is in the second position, thereby enabling the stacking bar 300 to be stably held in place with respect to the side plate 230 without being accidentally dropped into the first position. Thus, when the stacking lever 300 is in the second position, the stacking lever 300 clears the opening of the box 200 so that the upper epicyclic container 100 can be nested within the lower empty epicyclic container 100. Preferably, the inside of the stacking bar 300 in this position is flush with the side plate 230 so that the upper epicyclic container 100 can be placed more smoothly into the lower epicyclic container 100.
As also shown in fig. 1, a circumferential edge portion 232 is provided at the upper edge of the side plate 230, the circumferential edge portion 232 projecting outwardly from the upper edge of the side plate 230, and a downwardly opening cavity 233 (see fig. 4) is provided, the cavity 233 being located outside the side plate 230 and having a width at a corresponding location greater than a thickness at a corresponding location of the pair of stacking bars 300, so that when the upper epicyclic container 100 is nested in the lower empty epicyclic container 100, the stacking bars 300 in the second position can be received in the cavity 233, so that the upper epicyclic container 100 is nested as deep as possible in the lower epicyclic container 100.
In the illustrated preferred embodiment, the stacking rod 300 is detachably hinged to the circumferential edge portion 232 of the side plate 230 by a snap-fit connection. Specifically, as shown in fig. 3, the stacking bar 300 is provided with the protruding portion 320 protruding downward when in the second position, and the circumferential edge portion 232 of the side plate 230 is provided with a corresponding opening portion 2321, the opening portion 2321 being opened upward and inward. On both sides of the protruding portion 320, there are provided pivot shafts 321 protruding in the extending direction of the stacking lever 300, and on both sides of the opening portion 2321 in the extending direction of the circumferential edge portion 232, there are provided receiving holes 2322 for receiving the pivot shafts 321, so that the pivot shafts 321 can rotate in the receiving holes 2322, thereby achieving pivoting of the stacking lever 300 with respect to the side plate 230. Guide surfaces may be provided at both sides of the opening 2321 to facilitate the easy installation of the pivot shaft 321 to the receiving hole 2322. It should be understood that it is also possible to provide an opening portion and a receiving hole on the stacking lever 300, and a protruding portion and a pivot shaft on the circumferential edge portion 232. It should also be understood that the pivotal connection between the stacking rod 300 and the circumferential edge 232 may also be non-removable, and the two may also be hinged by other means known in the art.
In the preferred embodiment shown, each stacking bar 300 is provided with two extensions 320, while each side plate 230 is correspondingly provided with two openings 2321. In this case, when the stacking bar 300 is in the first position, the stacking bar 300 is supported at four positions, two intersection positions and the upper edge of the adjacent side plate 220, whereby the upper epicyclic container 100 can be supported more strongly. It should be understood that each stacking bar 300 may be hinged to the side panel 230 at one or more than three locations, even throughout its length, so that the stacking bar 300 can be supported at more locations when in the first position.
It is also preferred that the side of the stacking bar 300 facing upwards in the first position is provided with a relief complementary to the bottom of the box 200, as shown in fig. 4. In the embodiment shown in fig. 5, the bottom surface of the bottom plate 210 of the box body 200 is provided with a rib 211 near the side plate 230, and the upper surface of the stacking bar 300 is provided with a corresponding rib 340, and when the upper circulation container 100 is stacked in place, the ribs 340 are located on both sides of the rib 211, so that the upper circulation container 100 can be prevented from sliding along the extending direction of the side plate 220, and the upper circulation container 100 can be placed on the stacking bar 300 more firmly. It should be understood that other shapes of the concave-convex structure may be provided on the bottom surface of the bottom plate 210 corresponding to the stacking bar 300, and the corresponding complementary structure may be provided on the upper surface of the stacking bar 300. In the illustrated embodiment, the upper edge of the side plate 220 is also provided with a circumferential edge portion 222, the circumferential edge portion 222 protrudes outward from the upper edge of the side plate 220, the circumferential edge portion 222 and the circumferential edge portion 232 are connected to each other to form a substantially rectangular frame, and at least a portion of the substantially rectangular frame formed by the circumferential edge portion 222 and the circumferential edge portion 232 is provided with a closed cavity 250 extending along the respective circumferential edge portion 222 or 232. The provision of the closed cavity 250 provides the substantially rectangular frame formed by the peripheral edge portions 222 and 232 with greater strength. So as to resist deformation by the load when the stacking bar 300 is in the first position and the relatively heavy loaded epicyclic container 100 is carried above.
While the preferred embodiments of the present invention have been described in detail above, it should be understood that aspects of the embodiments can be modified, if necessary, to employ aspects, features and concepts of the various patents, applications and publications to provide yet further embodiments.
These and other changes can be made to the embodiments in light of the above detailed description. In general, in the claims, the terms used should not be construed to be limited to the specific embodiments disclosed in the specification and the claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which such claims are entitled.
