Description

Technical Field

[0001] This invention relates to the field of storage boxes, and particularly to an insulated container. Background Technology

[0002] With the improvement of living standards and the rapid development of the catering industry, food delivery has become a new profit growth point for the catering industry. Enjoying various delicacies at home with family has also become a healthy and natural lifestyle, which is more common in developed countries and is becoming increasingly popular in China. Insulated containers have attracted the attention of the catering industry due to their safety, environmental protection, ability to keep food cold or hot, and portability.

[0003] The inventors discovered that existing insulated containers are generally made by directly splicing together multiple insulation boards. Each insulation board typically consists of two parallel reinforcing plates with an insulation board sandwiched between them. To ensure the connection strength at the joint of the two insulation boards, insulation material is generally not allowed at the joint. As a result, the insulation performance at the joint of the insulated container is poor, which reduces the overall insulation performance of the container. Summary of the Invention

[0004] The purpose of this invention is to provide an insulated container that can improve the heat preservation performance of the container.

[0005] To address the aforementioned technical problems, embodiments of the present invention provide an insulated container, the insulated container comprising a housing, the housing comprising:

[0006] The inner liner has an inner bottom plate and an inner side plate extending upward from the outer periphery of the inner bottom plate;

[0007] An outer shell, which is fitted around the outer periphery of the inner liner and has an outer bottom plate and outer side plates extending upward from the outer periphery of the outer bottom plate, wherein the inner bottom plate and the outer bottom plate, as well as each of the inner side plates and its corresponding outer side plate, are spaced apart, forming a cavity between the inner liner and the outer shell; and

[0008] A thermal insulation layer is disposed in the cavity;

[0009] Each of the outer side panels extends outward from the outer bottom plate to form an outer edge around the box; each of the inner side panels extends outward from the inner bottom plate to form an inner edge around the box, and the inner edge and the outer edge interlock with each other.

[0010] Compared to existing technologies, the embodiments of this invention, in which the insulated container comprises an inner liner and an outer shell, with the inner liner and outer shell separated to form a cavity, and the insulation layer disposed within the cavity, mean that the insulated container is not composed of several insulation panels spliced ​​together. Therefore, there are no splicing points, and thus no weak points in insulation at the splicing areas, thereby improving the insulation performance of the insulated container. Furthermore, the inner bottom plate and the outer bottom plate, as well as each of the inner side plates and their respective opposite outer side plates, are spaced apart to fill with the insulation layer, thereby effectively improving the insulation performance of the insulated container.

[0011] In addition, since each outer side panel extends outward from the bottom plate to form an outer eave, and each inner side panel extends outward from the bottom plate to form an inner eave, the inner and outer eaves are interlocked with each other. This interlocking prevents the insulation layer from falling out of the cavity. Furthermore, the interlocking of the inner and outer eaves improves the ease of use of the insulation container.

[0012] In one embodiment, one of the outer eaves and the inner eaves is provided with multiple slots, and the other is provided with multiple fasteners. Each slot is arranged around the axis of the insulation container, and each fastener is correspondingly fastened into its respective slot.

[0013] In one embodiment, the end of the inner eaves extends downward by a predetermined distance to form a first extension, and the end of the outer eaves extends downward by a predetermined distance to form a second extension;

[0015] In one embodiment, the slot is disposed on the outer edge, the slot extends along the extending direction of the second extension, and opens toward the upper end of the second extension;

[0016] The snap-fit ​​component is disposed on the side of the first extension portion facing the second extension portion. The snap-fit ​​component extends along the extension direction of its corresponding slot and is inserted into its corresponding slot.

[0017] In one embodiment, the snap-fit ​​component includes:

[0018] A connecting block, which is fixedly connected to the first extension and is disposed perpendicular to the first extension;

[0019] A snap-fit ​​block, which is fixedly connected to the connecting block and is set perpendicular to the connecting block;

[0020] The shape of the slot is adapted to the shape of the connector.

[0021] In one embodiment, the outer diameter of the snap-fit ​​block gradually decreases from top to bottom along the extending direction of the first extension, near the end of the first extension.

[0022] In one embodiment, the outer ring surface of the snap-fit ​​member has a protrusion, and the second extension defines a limiting groove on the groove wall of the snap-fit ​​slot. The protrusion and the limiting groove snap into each other along the height direction of the insulation container.

[0023] In one embodiment, the limiting groove extends upward from the end of the second extension, and the protrusion abuts against the top of the limiting groove.

[0024] In one embodiment, the housing further includes a plurality of reinforcing plates that are respectively fixedly connected to the outer surface of the outer side plate and the second extension.

[0025] In one embodiment, each of the outer side plates extends radially outward from the outer bottom plate along the outer edge of the insulated container to form an inner rim, and the inner liner also includes a limiting ring extending upward from the radially extending inner rim.

[0026] In one embodiment, the inner liner has a storage cavity, and the portion of the inner liner defining the storage cavity is spaced apart from the outer shell by at least a predetermined distance to fill the insulation layer.

[0027] In one embodiment, the insulation layer is a solid board, or the material of the insulation layer is an insulating foaming agent or a liquid insulating material.

[0028] In one embodiment, the insulated container further includes a lid that covers the opening of the container body, the lid comprising:

[0029] Inner panel;

[0030] The outer panel is disposed opposite to the inner panel;

[0031] The outer ring of the outer panel is fixedly connected to the outer ring of the inner panel, the middle area of ​​the outer panel is separated from the inner panel to form a heat insulation cavity, and the box cover also includes a heat insulation layer located in the heat insulation cavity.

[0053] The singular forms “a” and “the” used in this specification and the appended claims include plural references unless otherwise expressly stated herein. It should be noted that the term “or” is generally used to mean “and / or” unless otherwise expressly stated herein.

[0054] In the following description, in order to clearly demonstrate the structure and working method of the present invention, a number of directional terms will be used. However, terms such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and not as limiting terms.

[0055] The following describes embodiments of the heat-insulating container of the present invention with reference to the accompanying drawings, such as... Figures 1 to 6 As shown, the insulated container includes a box body 10, which includes an inner liner 1, an outer shell 2, and an insulation layer 3. The inner liner 1 has an inner bottom plate 11 and inner side plates 12 extending upward from the outer periphery of the inner bottom plate 11. The outer shell 2 is fitted around the outer periphery of the inner liner 1 and has an outer bottom plate 21 and outer side plates 22 extending upward from the outer periphery of the outer bottom plate 21. The inner bottom plate 11 and the outer bottom plate 21 are spaced apart, as are each inner side plate 12 and its corresponding outer side plate 22, forming a cavity 4 between the inner liner 1 and the outer shell 2. The insulation layer 3 is disposed in the cavity 4, and each outer side plate 22 extends outward from the outer bottom plate 21 to form an outer rim 23, and each inner side plate 12 extends outward from the inner bottom plate 11 to form an inner rim 14. The inner rim 14 and the outer rim 23 are interlocked.

[0056] Compared to existing technologies, the embodiments of this invention, including an inner liner 1 and an outer shell 2, with the inner liner 1 and outer shell 2 separated to form a cavity 4 and an insulation layer 3 disposed within the cavity 4, demonstrate that the insulated container is not composed of several insulation panels joined together. Therefore, there are no joints or weak points in the insulation at these joints, thus improving the insulation performance of the container. Furthermore, the inner bottom plate 11 and the outer bottom plate 21, as well as each inner side plate 12 and its corresponding outer side plate 22, are spaced apart to accommodate the insulation layer 3, further enhancing the insulation performance of the container.

[0057] In addition, since each outer side plate 22 extends outward from the outer bottom plate 21 to form an outer eave 23, and each inner side plate 12 extends outward from the inner bottom plate 11 to form an inner eave 14, the inner eave 14 and the outer eave 23 are interlocked with each other. Through the interlocking between the inner eave 14 and the outer eave 23, the insulation layer 3 can be prevented from falling out of the cavity 4. Moreover, the inner eave 14 and the outer eave 23 are interlocked together, thereby improving the ease of use of the insulation container.

[0058] Multiple slots 232 are provided on either the outer eaves 23 or the inner eaves 14, and multiple snap-fit ​​pieces 142 are provided on the other. Each slot 232 is arranged around the axis of the insulation container, and each slot 232 piece is snapped into its corresponding slot 232.

[0059] The end of the inner eaves 14 extends downward by a predetermined distance to form a first extension 141, and the end of the outer eaves 23 also extends downward by a predetermined distance to form a second extension 231. The slot 232 is provided on either the first extension 141 or the second extension 231, while the snap-fit ​​member 142 is provided on the other of the first extension 141 and the second extension 231.

[0060] Specifically, such as Figure 3 and Figure 6 As shown, in this embodiment, both the inner eaves 14 and the outer eaves 23 extend radially outward from the insulation container and then extend downward to form the first extension 141 and the second extension 231, respectively.

[0061] The slot 232 and the snap-fit ​​member 142 can be respectively disposed on the radially extending portions of the inner eaves 14 and the outer eaves 23, or they can be disposed on the first extension 141 and the second extension 231. In this embodiment, the slot 232 and the snap-fit ​​member 142 are respectively disposed on the first extension 141 and the second extension 231.

[0062] like Figure 6 As shown, a slot 232 is provided on the outer edge 23, and the slot 232 extends along the extension direction of the second extension 231 and opens toward the upper end of the second extension 231. A snap-fit ​​member 142 is provided on the side of the first extension 141 facing the second extension 231, and the snap-fit ​​member 142 extends along the extension direction of its corresponding slot 232 and is inserted into its corresponding slot 232.

[0063] like Figure 6As shown, the snap-fit ​​component 142 includes a connecting block 1421 and a snap-fit ​​block 1422. The connecting block 1421 is fixedly connected to the first extension 141 and is disposed perpendicular to the first extension 141. The snap-fit ​​block 1422 is fixedly connected to the connecting block 1421 and is disposed perpendicular to the connecting block 1421. The shape of the slot 232 is adapted to the shape of the snap-fit ​​block 1422. The slot 232 includes a connecting groove 2321 and a snap-fit ​​groove 2322. The connecting groove 2321 is used to insert the connecting block 1421, and the snap-fit ​​groove 2322 is used to insert the snap-fit ​​block 1422. The connecting groove 2321 and the snap-fit ​​groove 2322 are perpendicular to each other and communicate with each other.

[0064] In addition, in order to facilitate the insertion of the snap-fit ​​block 1422 into the snap-fit ​​slot 2322, the outer diameter of the snap-fit ​​block 1422 near the end of the first extension 141 along the extension direction of the first extension 141 gradually decreases from top to bottom, that is, the lower section of the snap-fit ​​block 1422 gradually decreases from top to bottom, so that the snap-fit ​​block 1422 can be more easily inserted into the snap-fit ​​slot 2322.

[0065] In addition, such as Figure 6 and Figure 7 As shown, to restrict the inner liner 1 from moving up and down along the axis of the insulation container, the outer ring surface of the snap-fit ​​member 142 also has a protrusion 1423, and the second extension 231 defines a limiting groove 233 on the groove wall of the snap-fit ​​groove 232. The protrusion 1423 and the limiting groove 233 are snapped together along the height direction of the insulation container. Specifically, as shown... Figure 6 As shown, the limiting groove 233 extends upward from the end of the second extension 231, and the protrusion 1423 abuts against the top 2331 of the limiting groove 233. Of course, in some embodiments, the limiting groove 233 can also be directly formed on the groove wall of the slot 232 and not open towards the end of the second extension 231. The protrusion 1423 is directly and elastically inserted into the limiting groove 233.

[0066] Additionally, it should be noted that in some embodiments, the slot 232 may be formed on the radially extending portion of the outer eaves 23 and arranged vertically. The snap-fit ​​member 142 is disposed on the radially extending portion of the inner eaves 14 and is also vertically arranged, forming a column whose shape matches the slot 232. When the inner liner 1 is placed inside the outer shell 2 from top to bottom, the column is inserted into its corresponding slot 232 and is press-fitted with the slot 232. Of course, the positions of the slot 232 and the column can be interchanged; the upper slot 232 can be disposed on the radially extending portion of the inner eaves 14, while the column can be disposed on the radially extending portion of the outer eaves 23.

[0067] Additionally, it should be noted that in this embodiment, both the inner liner 1 and the outer shell 2 of the insulated container are supported by plastic material. Of course, in some embodiments, the inner liner 1 and the outer shell 2 can also be made of other materials, as long as they do not depart from the scope of this invention. For example, they can be made of wood.

[0068] The insulation layer 3 is a solid board, such as foam board. In actual installation, the insulation layer 3 can be placed inside the outer shell 2 first, and then the inner liner 1 can be inserted into the inner side of the insulation layer 3 from top to bottom. At this time, the snap-fit ​​blocks 1422 on the inner eaves 14 are inserted into their corresponding snap-fit ​​slots 232 from top to bottom, thereby snapping the inner eaves 14 and the outer eaves 23 together, and thus fixing the inner liner 1 and the outer shell 2 together. Of course, in some embodiments, the material of the insulation layer 3 can also be a thermal insulation foam or a liquid thermal insulation material. For example, polyurethane foam can be used, or a liquid thermal insulation material as shown in the patent with publication number CN1093391A can be used. When the insulation layer 3 is a liquid material, through holes can be opened in the radially extending part of the inner eaves 14. When the inner liner 1 is placed inside the outer shell 2, the thermal insulation foam and liquid thermal insulation material are injected into the cavity 4 through the through holes. At this time, the through holes can be sealed.

[0069] In addition, such as Figure 6 As shown, the outer casing 2 also includes multiple reinforcing plates 25 that are respectively fixedly connected to the outer surface of the outer side plate 22 and the second extension 231. Preferably, the reinforcing plates 25 are fixedly connected to the second extension 231 on the side facing each outer side plate 22, and each reinforcing plate 25 is vertically arranged.

[0070] Furthermore, as can be seen from the above content, such as Figure 6 and Figure 7 As shown, each of the outer side plates 22 extends radially outward from the outer bottom plate 21 along the outer edge of the insulated container of the box body 10, forming an inner rim 14. The inner liner 1 also includes a limiting ring 17 extending upward from the radially extending inner rim 14. The limiting ring 17 is vertically disposed on the inner rim 14 and cooperates with the box cover 5 of the box body 10 to limit the position of the box cover 5.

[0071] In addition, preferred, such as Figure 3 and Figure 4 As shown, the outer surface of the corner 16 between two adjacent inner side panels 12 of the inner liner 1 is also covered by the insulation layer 3. Preferably, the outer surface of the corner 16 between each inner side panel 12 and the inner bottom panel 11 is also covered by the insulation layer 3. This ensures that the corner 16 is also covered, thereby further improving the insulation performance of the insulated box.

[0072] In addition, preferred, such as Figure 2 As shown, the inner liner 1 has a storage cavity 13. The area of ​​the inner liner 1 that defines the storage cavity 13 is separated from the outer shell 2 by at least a preset distance to fill the insulation layer 3. Therefore, the insulation layer 3 can completely cover the entire storage cavity 13 to ensure the temperature inside the storage cavity 13.

[0073] In addition, such as Figure 3As shown, since the ends of the outer eaves 23 and the inner eaves 14 both extend downwards by a certain distance, the inner eaves 14 and the outer eaves 23 can also form a handle, making it convenient for users to move the insulated container.

[0074] like Figure 4 As shown, the outer bottom plate 21 of the outer casing 2 also has a support portion 24 protruding outward from the box body 10. This support portion 24 can support the entire box body 10. Specifically, the support portion 24 can be externally mounted, or it can be formed by the outer bottom plate 21 of the outer casing 2 protruding inward from the box body 10. In this embodiment, the support portion 24 is a ring of protruding ridges provided along the edge of the outer bottom plate 21. Of course, in some embodiments, the support portion 24 can also be multiple protrusions, each protruding on the outer bottom plate 21.

[0075] In addition, such as Figure 8 and Figure 9 As shown, the box body 10 also includes a partition 7, which operably divides the space inside the box body 10 into two areas. A portion of the inner liner 1 of the box body 10 protrudes inward to form a pair of partition 7 limiting portions 15. The pair of partition 7 limiting portions 15 are positioned opposite each other on both sides of the partition 7 and are engaged with the partition 7. Specifically, as... Figure 10 As shown, each of the pair of partition 7 limiting portions 15 includes a pair of ribs 151 extending along the height direction of the housing 10. The pair of ribs 151 are spaced apart from each other along a direction perpendicular to the height of the housing 10 to form a snap-fit ​​area, and any edge of the partition 7 is located within this snap-fit ​​area. Since the partition 7 limiting portion 15 is formed by the inner liner 1 protruding into the housing 10, the partition 7 limiting portion 15 can be integrally formed during the forming process of the inner liner 1, such as during injection molding, thereby improving the manufacturing convenience of the housing 10. Similarly, during the forming process of the outer shell 2, such as during injection molding, the support portion 24 can also be integrally formed.

[0076] In addition, such as Figure 8 and Figure 9 As shown, each of the inner side panels 12 and each of the outer side panels 22 gradually slopes inward from top to bottom into the box 10. That is, the cross-section of the entire box 10 gradually decreases from top to bottom, so that the lower section of such a box 10 can be placed into another box 10, thereby facilitating the storage of the box 10.

[0077] like Figure 2 , Figure 3 and Figure 11As shown, the insulated container also includes a lid 5, which covers the opening of the container body 10. The lid 5 includes an inner plate 51 and an outer plate 52, wherein the outer plate 52 is disposed opposite to the inner plate 51; the outer ring of the outer plate 52 is fixedly connected to the outer ring of the inner plate 51, for example, by gluing or welding. The middle area of ​​the outer plate 52 is separated from the inner plate 51 to form an insulation cavity 53. The lid 5 also includes a heat insulation layer 54 located within the heat insulation cavity 53. Additionally, as... Figure 6 As shown, the outer ring of the outer panel is recessed upwards on the side facing the box to form a groove 521. When the box cover is closed on the box, the limiting ring 17 is inserted into the groove 521.

[0078] Additionally, a portion of the inner panel 51 protrudes away from the outer panel 52 to form a suspension section for suspending the cold storage plate 6. For example... Figures 11 to 13 As shown, the suspension part includes a first protrusion 55 and a second protrusion 56 disposed opposite to each other on both sides of the cold storage plate 6, with the cold storage plate 6 located between the first protrusion 55 and the second protrusion 56. The end of the first protrusion 55 extends toward the second protrusion 56, with the extended portion of the first protrusion 55 located on the side of the cold storage plate 6 away from the outer plate 52. The end of the second protrusion 56 extends toward the first protrusion 55, with the extended portion of the second protrusion 56 located on the side of the cold storage plate 6 away from the outer plate 52. Thus, the first protrusion 55 and the second protrusion 56 form two hooks that hook the cold storage plate 6, thereby fixing the cold storage plate 6 in place. When it is necessary to disassemble the cold storage plate 6, it is only necessary to pull the cold storage plate 6 out from between the first protrusion 55 and the second protrusion 56.
