Referring initially to FIG. 1, a container assembly 100 is shown in FIG. 1 in accordance with an embodiment of the present invention. The container assembly 100 includes a container 200 and a cold thermal storage assembly 300 (see fig. 2) placed in conformity with the inner surface of the container 200. The container 100 comprises a base 1, two pairs of opposing side walls 2 and 3 extending perpendicularly from the base 1 and interconnected to each other, and a cover 4. In the illustrated embodiment, the lid 4 is hinged to the upper edge of one of the side walls 3 by a hinge. It should be understood that the lid 4 may also be a separate component for covering the opening of the container 200 after the container 200 is filled. In the illustrated embodiment, the two pairs of opposing sidewalls are foldable relative to the base. It will be appreciated that the side walls may also be fixedly attached to the base, i.e. the side walls cannot be folded relative to the base. The number of the side walls is not limited to 4, and for example, the side walls may be circular side walls formed integrally, or may be side walls enclosing a cylindrical body having a triangular or fan-shaped cross section.

A cold storage assembly 300 is placed inside the container 200 as shown in fig. 2. In the embodiment shown in fig. 2, two cold thermal storage assemblies 300 are disposed within the container 200. Fig. 3 shows a perspective view of a cold storage assembly 300.

The cold accumulation assembly 300 is composed of at least two cold accumulation plates hinged to each other. The cold storage plate comprises a cold storage plate shell and a phase change cold storage material, and the cold storage plate shell is provided with internal mutually communicated spaces for containing the phase change cold storage material. It should be understood that the cold storage plate may be made of any known suitable material as long as it can perform the cold storage function. The shape of the cold storage plates may be any suitable shape, such as rectangular, circular, fan-shaped, etc. The cool storage material accommodated inside may be a phase change cool storage material, or may be a magnetic cool storage material, for example.

In the embodiment shown in fig. 2 to 5, the

cold storage plates

301, 302 have a plate-shaped main body 303 and a plurality of through holes 304 distributed on the plate-shaped main body 303. The plate-shaped main body is internally provided with a closed hollow space for accommodating cold storage materials. The cold storage plate is also provided with a filling port 305 for filling the hollow space with cold storage material. The edge of the plate-like body is provided with a bevel 306. Therefore, when two adjacent cold storage plates are connected with each other, the cold storage plates can be partially overlapped, so that a better heat preservation effect is achieved.

As shown in fig. 3, the cold storage assembly 300 includes a plurality of cold storage plates. The cold storage plate includes a cold storage bottom plate 301 and three cold storage side plates 302 hinged to three edges of the cold storage bottom plate 301. It is to be understood that the cold storage assembly 300 may also include any one or any two of the cold storage bottom plate 301 and the three cold storage side plates 302. In the illustrated embodiment, the cold storage base plate 301 has a rectangular shape, but it should be understood that when the edge of the cold storage base plate 301 is hinged with two cold storage side plates 302, the cold storage base plate 301 may be a cold storage plate having a right angle, such as a right-angled triangular cold storage plate, a right-angled fan-shaped cold storage plate, and the like. When the edge of the cold accumulation bottom plate 301 is only hinged to one cold accumulation side plate 302, the cold accumulation bottom plate 301 and the cold accumulation side plate 302 may have any suitable shape as long as the two have mutually hinged straight edges, and the cold accumulation bottom plate may have one straight edge, two straight edges, three straight edges, four straight edges, or more straight edges.

The cold storage bottom plate 301 and the cold storage side plate 302 are pivotable relative to each other, and are switched between a first position perpendicular to each other and a second position flush with each other (see fig. 6). When the cold accumulation bottom plate 301 and the cold accumulation side plate 302 are in the first position, the cold accumulation assembly 300 can be placed in the container 200, and the cold accumulation bottom plate 301 and the cold accumulation side plate 302 respectively abut against the bottom wall and the side wall of the container 200. And when the cold accumulation base plate 301 and the cold accumulation side plate 302 are in the second position, the cold accumulation assembly 300 can be conveniently stacked and stored.

When the cold storage assembly 300 includes more than two cold storage side plates 302, it is preferable that adjacent edges of adjacent two cold storage side plates 302 have a pair of contact surfaces that contact each other, the pair of contact surfaces being angled with respect to any one of the adjacent cold storage side plates. Thus, when the cold storage assembly 300 is placed in the container 200 in the first position, the cold storage side plate 302 is in contact with the contact surface of the edge of the adjacent cold storage side plate 302 through the contact surface at an angle, thereby preventing the adjacent cold storage side plate 302 from collapsing away from the second position toward the inside of the container 200 with respect to the cold storage bottom plate 301. Preferably, a pair of contact surfaces are angled at 45 ° with respect to the adjacent cold storage side plate 302, thereby more effectively preventing the adjacent cold storage side plate 302 from collapsing inward.

An enlarged view of a detail of fig. 3 is shown in fig. 4A and 4B. As shown in fig. 4A and 4B, the bottom edge of the cold storage side plate 302 is provided with at least one downward extending portion 3021, and both sides of the downward extending portion 3021 in the direction of the bottom edge of the cold storage side plate are provided with rotating shafts 3022 extending parallel to the bottom edge of the cold storage side plate. The edge of the cold accumulation bottom plate 301 is provided with a rotating shaft limiting part 3012, and the rotating shaft limiting part 3012 is a cavity extending along the edge direction of the floor 301. The rotating shaft 3022 can be accommodated in the rotating shaft limiting portion 3012 and rotate therein, thereby realizing the hinge connection between the cold storage side plate 302 and the cold storage bottom plate 301. It is to be understood that the cold accumulation base plate 301 and the cold accumulation side plate 302 may be hinged to each other using any structure known in the art.

A perspective view of the container assembly 300 is shown in fig. 5 with the hinge portion cut away. An enlarged view of the cut-away portion of fig. 5 is shown in fig. 5A. In the illustrated embodiment, when the cold storage bottom plate 301 and the cold storage side plate 302 are in the first position perpendicular to each other, the bottom edge lower surface of the cold storage side plate 302 abuts against the upper surface edge of the cold storage bottom plate 301. Preferably, a side plate limiting part 3025 and a bottom plate limiting part 3015 are respectively disposed on the lower surface of the bottom edge of the cold storage side plate 302 and the edge of the upper surface of the cold storage bottom plate 301. In the illustrated embodiment, the side plate stopper 3025 is a slot, and the bottom plate stopper 3015 is a protrusion that can be inserted into the slot. It should be understood that the side plate limiter 3025 may be a protrusion, and the bottom plate limiter 3015 may be a slot capable of receiving the protrusion. It is also contemplated that one of the side panel restraint portion 3025 and the bottom panel restraint portion 3015 may be a protrusion of another shape and the other may be a complementary shaped cavity to receive the protrusion. Thus, when the cold storage bottom plate 301 and the cold storage side plate 302 are in the mutually perpendicular position, the cooperation between the side plate limiting portion 3025 and the bottom plate limiting portion 3015 can keep the cold storage bottom plate 301 and the cold storage side plate 302 in the mutually perpendicular position without being accidentally hinged to the second position.

A perspective view of the cold storage assembly 300 in the first and second positions, respectively, is shown in fig. 6. In the first position, the three cold storage side plates 302 extend vertically upward from three edges of the substantially rectangular cold storage bottom plate 301. Preferably, the height edges of adjacent two of the three cold accumulation side plates 302 contact each other, so that a larger cooling area can be formed. In the second position, the three cold accumulation side plates 302 and the cold accumulation bottom plate 301 are in the same plane. In this state, the cold storage module 300 can be conveniently stacked and stored, and can be conveniently put into the freezing chamber for freezing. Fig. 7 shows other

different embodiments

310 and 320 of the cold storage assembly according to the invention. The cold accumulation assembly 310 comprises a cold accumulation bottom plate and a cold accumulation side plate hinged with the edge of the cold accumulation bottom plate. And the cold accumulation assembly 320 comprises a cold accumulation bottom plate and two cold accumulation side plates hinged with the edges of the cold accumulation bottom plate.

As shown in fig. 2, two cold storage assemblies 300 are placed inside the container 200. Preferably, the size of the cold storage bottom plate 301 of each cold storage assembly 300 is approximately equal to half of the bottom wall of the container 200, so that two cold storage assemblies 300 are oppositely placed side by side to just cover the bottom wall of the container 200, and the cold storage side plates 302 of the two cold storage assemblies 300 in the first position are close to the side walls of the container 200. Therefore, after the cold storage assembly 300 is placed in place within the container 200, the filling of the cargo within the container 200 is not affected. And when the goods in the container 200 are partially taken out, the cold accumulation side plate 302 can still be kept in place without collapsing to damage the goods.

In addition, due to the above size arrangement of the cold accumulation bottom plate 301 of the cold accumulation assembly 300, when the cold accumulation assembly 300 is placed into the container 200, only the cold accumulation bottom plate 301 needs to be aligned with and placed in parallel with a half of the bottom wall of the container 200, and the corresponding cold accumulation side plates can automatically enter the first position from the second position under the guiding action of the container 200. Therefore, the above-described dimensioning of the cold storage assembly 300 makes it possible to put it into the container 200 very conveniently and efficiently.

It is to be understood that the

cold storage assembly

310 or 320, or any of the embodiments mentioned above, may also be placed within the container 200.

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.
