Description

Technical Field

[0001] An embodiment of the present invention relates to a container, and particularly to a foldable insulated box. Background Art

[0002] Existing insulated containers are generally made of EPS or EPP foaming materials. Such materials have good toughness but poor rigidity. When using, after placing goods in the container, the lid is covered on the box body and then delivered. For such insulated boxes, the general external dimensions are 600*400*300mm, and the internal volume is about 45 liters. Such insulated containers are mainly used for fresh food delivery. After sorting pre-cooled fresh food or frozen products in a cold storage, they are loaded into the insulated box together with cold storage plates and then delivered to households.

[0064] Embodiments of the present invention are described below with reference to the accompanying drawings. As Figure 1 、 Figure 2 and Figure 14 shown, the foldable incubator 100 includes a box body 20 having an opening 30, a lid 4 covering the opening 30, and a cold storage member 42 disposed inside the foldable incubator 100. The box body 20 has a base 1 and two pairs of opposite side plates 2 and 3 foldable with respect to the base 1. Biting portions 202 and 302 are provided at the longitudinal ends of the side plates 2 and 3 respectively. When each side plate stands upright relative to the base 1, the side plates 2 and 3 are connected by biting each other through the biting portions 202 and 302, so as to jointly form the internal volume of the foldable container 100 with the base 1, and the lid 4 can cover the opening 30 of the foldable incubator 100. When the side plates 2, 3 and the lid 4 are folded relative to the base 1, the foldable incubator 100 can be conveniently stored and transported. It should be understood that the connection manner between the side plates 2 and 3 is not limited to the above-mentioned biting manner, as long as the internal space can be enclosed by connecting end to end with each other. At least one first connecting member 5 is embedded at the bottom of the side plate 2 and the bottom of the side plate 3, and at least one second connecting member 6 is embedded on two opposite sides of the base 1, and the plurality of first connecting members 5 are respectively hinged to the plurality of second connecting members 6. In this embodiment, the first connecting members 5 are all embedded at the bottom of the side plates 2 and 3, and the second connecting members 6 are all embedded in the base 1.

[0065] It can be understood that at least one first connecting member 5 is integrally formed with the side plates 2 and 3. Or at least one second connecting member 6 is also integrally formed with the base 1. Specifically, there are various matching forms.

[0066] The first connecting member 5 connected to the side plate 2 and the side plate 2 are integrally formed into an independent integral part, and the first connecting member 5 connected to the side plate 3 and the side plate 3 are integrally formed into an independent integral part. Alternatively, the second connecting member 6 connected to the base 1 and the base are integrally formed into an independent integral part.

[0067] Furthermore, a part of the first connecting member 5 connected to the side plate 2 is integrally formed with the side plate 2, and a part is embedded in the side plate 2; the first connecting member 5 integrally formed with the side plate 2 can be one or more, and the first connecting member 5 embedded in the side plate 2 can also be one or more. The same is true for the second connecting member on the side plate 3. A part of the second connecting member 6 connected to the base 1 is integrally formed with the base 1, and a part is embedded in the base 1; the second connecting member 6 integrally formed with the base 1 can be one or more, and the second connecting member 6 embedded in the base 1 can also be one or more.

[0068] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the base 1 has a bottom plate 11 and two pairs of opposite side guards extending upward from two pairs of opposite edges of the bottom plate 11, namely the side guard 12 and the side guard 13. The second connecting member 6 is embedded in the side guard 12, and the second connecting member 6 in one side guard 12 can be one or more. The second connecting member 6 is embedded in the side guard 13, and the second connecting member 6 in one side guard 13 can be one or more. Among them, when the side plate 2 is upright relative to the base 1, a section extending downward from the top edge of the first side guard 12 overlaps with a section extending upward from the bottom edge of the corresponding side plate 2. When the side plate 3 is upright relative to the base 1, a section extending downward from the top edge of the side guard 13 overlaps with a section extending upward from the bottom edge of the corresponding side plate 3, so as to ensure the sealing between the side plate and the base 1, reduce the energy loss in the box body 20, and ensure the overall heat insulation effect of the box body 20. In this embodiment, when the side plate 2 and the side plate 3 are upright, it can be understood as the upright state of the side plate 2 and the side plate 3 in the normal use state of the foldable insulation box 100.

[0069] To make the foldable insulation box 100 have a better heat insulation effect, the box body 20 and the lid 4 are generally made of EPS or EPP foaming materials, and this kind of material has good toughness and poor rigidity. The first connecting member 5 and the second connecting member 6 are thicker than ordinary engineering plastic parts to ensure the realization of their strength and functions, such as Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6As shown, the first connecting member 5 is now embedded in the side plates 2 and 3, and the second connecting member 6 is embedded in the base 1. The side plates 2 and 3 wrap part of the first connecting member 5, and the base 1 wraps part of the second connecting member 6, so that the first connecting member 5 is firmly connected to the side plates 2 and 3, and the second connecting member 6 is firmly connected to the base 1, realizing the foldability of the box body 20.

[0070] As Figure 1 、 Figure 2 shown, the side plate 2 is a long side plate with a longer length, and the side plate 3 is a short side plate with a shorter length. The folding structure of the side plate 2 and the edge guard 12 is similar to the folding structure of the side plate 3 and the edge guard 13. Now, the folding structure of the side plate 2 and the edge guard 12 will be specifically described as an example. The side plate 2 includes: a side plate body 21 and an extension part 22 extending downward from the lower edge of the side plate body 21, and at least part of the first connecting member 5 is embedded in the extension part 22. When each side plate 2 is upright relative to the base 1, the edge guard 12 overlaps with the extension part 22 of the corresponding side plate 2, that is, the extension part 22 is located on the inner side surface of the edge guard 12 and is attached to the inner side surface of the edge guard 12.

[0071] Furthermore, as Figure 5 and Figure 12 shown, the extension part 22 has a groove 221 with an opening outward and downward, and the edge guard 12 is operably embedded in the groove 221. When the side plate 2 is upright, the top of the edge guard 12 abuts against the downward side of the groove 221, and the inner side surface of the edge guard 12 is attached to the side wall facing the groove 221.

[0072] Furthermore, as Figure 3 、 Figure 4 shown, each second connecting member 6 has a second embedding part 61 at least partially embedded in the corresponding edge guard 12 and a hinge part 62 connected to the second embedding part 61, and the hinge part 62 is arranged on the side of the corresponding edge guard 12 facing the inside of the box body 20. As Figure 5 、 Figure 6 、 Figure 7 、 Figure 9 shown, there are multiple extension parts 22, and at least two adjacent extension parts 22 are separated from each other to form a spacer 220. As Figure 2 shown, the first connecting member 5 has a first embedding part 51 at least partially embedded in the extension part 23 and a hinge shaft 52 connected to the first embedding part 51, and the hinge shaft 52 is arranged in the spacer 220. Among them, the hinge shaft 52 is rotatably and slidably connected to the hinge part 62.

[0073] Furthermore, as Figure 5 、 Figure 6 、 Figure 7 、 Figure 9As shown, a longitudinal groove 621 open at the top is formed in the hinge portion 62, and the hinge shaft 52 is at least partially received in the longitudinal groove 621. When the side plate 2 is folded into the box body 20, the hinge shaft rotates within the longitudinal groove 621 and can slide along the longitudinal groove 621, thereby changing the height of the side plate 2 after folding.

[0074] Furthermore, as Figure 10 、 Figure 11 shown, the first inlay portion 51 is detachably connected to the hinge shaft 52. When the hinge shaft 52 is damaged, the hinge shaft 52 can be directly replaced, saving costs.

[0075] In addition, as Figure 6 、 Figure 10 、 Figure 11 shown, at least a part of the first inlay portion 51 is located within the spacer 220. An installation position 533 is provided on the part of the first inlay portion 51 located within the spacer 220, and the hinge shaft 52 is arranged on the installation position 533.

[0076] Optionally, as Figure 6 、 Figure 10 shown, the installation position 533 is a protrusion extending along the height direction of the side plate. The hinge shaft 52 has a shaft body 521 and an installation sleeve 522 connected to the shaft body 521, and the installation sleeve 522 is slidably sleeved on the protrusion, making the installation and replacement of the hinge shaft 52 more convenient. It can be understood that the installation position 533 can also be a notch, and a boss can be provided on the hinge shaft 52 to be snapped into the notch.

[0077] Furthermore, as Figure 6 、 Figure 11 shown, at least a part of the first inlay portion 51 abuts against the side of the extension portion 22 forming the spacer 220 facing the spacer 220. A fixing recess 530 is provided on the side of the part of the first inlay portion 51 abutting against the extension portion 22 facing the spacer 220. The top of the hinge portion 62 has a hook body 622 that snaps into the fixing recess 530. After the side plate 2 is vertical, the side plate 2 and the side plate 3 are engaged, and the hook body 622 snaps into the fixing recess 530, and the edge guard 12 abuts against the lower side of the groove 221.

[0078] Optionally, the second inlay portion 61 and the hinge portion 62 connected to the second inlay portion 61 are integrally formed and can be a plastic or metal part. The first inlay portion 51 and the hinge shaft 52 connected to the first inlay portion 51 can also be integrally formed and can be a plastic or metal part.

[0079] Further, the box body 20 is generally made of EPS or EPP foaming material. To ensure the heat preservation effect, the box body 20 is maintained at a certain thickness. To keep the volume inside the box body 20 unchanged while ensuring the thickness of the box body 20, the second connecting member 6 is embedded in the base 1. And this material has good toughness and poor rigidity. To ensure the connection strength and stability between the second connecting member 6 and the base 1. As Figure 3 , Figure 4 , Figure 6 shown, each second embedding part 61 is provided with a second hollow part 610, and part of the edge guard 12 is filled in the second hollow part 610. Thus, while reducing the material and weight of the second embedding part 61, the second embedding part 61 is more tightly connected to the edge guard 12. In addition, due to the provision of the second hollow part 610, the second embedding part 61 occupies less area of the edge guard 12, leaving more material for the edge guard 12, so that the box body 20 has a better heat preservation effect.

[0080] Further, as Figure 3 , Figure 4 , Figure 6 shown, the second embedding part 61 has a second limiting member 612 inserted into the edge guard 12, and the second limiting member 612 has second branch parts 613 extending in different directions, so as to make the connection strength between the second connecting member 6 and the base 1 higher.

[0081] In addition, as Figure 3 , Figure 4 , Figure 6 shown, the area where the second embedding part 61 is embedded in the edge guard 12 also has a second protruding part 611 extending outward from the second hollow part 610, and the second protruding part 611 is embedded in the edge guard 12 filling the second hollow part 610.

[0082] It can be understood that the second embedding part 61 is also embedded in the edge guard 13.

[0083] Optionally, the second connecting member 6 and the base 1 can be injection molded, and the second embedding parts 61 of each second connecting member 6 are embedded in the base 1. Or, in other embodiments, the second connecting member 6 and the base 1 are also an integral whole.

[0084] In addition, to ensure the connection strength and stability between the first connecting member 5 and the base 1. As Figure 10 , Figure 11As shown, the first inlay portion 51 has a first hollow portion 510, and part of the side plate 2 is filled in the first hollow portion 510. The extension portion 22 of the side plate 2 is partially filled in the first hollow portion 510, and part of the side plate body 21 is also filled into the first hollow portion 510. It can be understood that only the extension portion 22 can be partially filled in the first hollow portion 510. While reducing the material and weight of the first inlay portion 51, the first inlay portion 51 is more closely connected to the side plate 2. In addition, the first inlay portion 51 occupies less area of the side plate 2, leaving more material for the side plate 2, so that the box body 20 has a better heat preservation effect.

[0085] Furthermore, as Figure 7 , Figure 9 shown, the structure of the side plate 3 is substantially the same as that of the side plate 2. The side plate 3 includes: a side plate body 31 and an extension portion 32 extending downward from the lower edge of the side plate body 31, and the first connecting member 5 is at least partially embedded in the extension portion 32. The structure of the embedded first connecting member 5 is substantially the same as the structure of the first connecting member 5 embedded in the side plate 2. In the structure of the first connecting member 5 embedded in the side plate 3, the first inlay portion 51 further has a first protrusion 511 extending outward from the first hollow portion 510, and the first protrusion 511 is embedded in the side plate 2 filling the first hollow portion 510, so that the connection strength between the first connecting member 5 and the side plates 2 and 3 is higher. It can be understood that the first connecting member 5 embedded in the side plate 2 can also have the first protrusion 511 inserted into the side plate 2. The technical detail structures of the first connecting member 5 embedded in the side plate 2 and the first connecting member 5 embedded in the side plate 3 can be applied to each other, and are not limited to one side plate.

[0086] In addition, the first inlay portion 51 has a first limiting member for inserting a protective edge. The first limiting member is a protrusion, and the protrusion has a first branch portion extending in different directions. Further, the connection strength between the first connecting member 5 and the base 1 is higher.

[0087] Optionally, the first connecting member 5 and the side plates 2 and 3 can be injection molded, and the first inlay portion 51 of each first connecting member 5 is embedded in the first connecting member 5 and the side plates 2 and 3. Or, in other embodiments, the first connecting member 5 and the side plates 2 and 3 are also an integral whole.

[0088] In addition, in some embodiments, as Figure 10 and Figure 11As shown, the first connecting member 5 is detachably connected to the side plate 2. When the first connecting member 5 needs to be replaced, the first connecting member 5 can be peeled off from the corresponding side plate.
