Description

Technical Field

[0001] This utility model relates to the field of vacuum insulation panel technology, and in particular to an irregularly shaped vacuum insulation panel and an insulation box. Background Technology

[0002] Vacuum insulation panels are a type of vacuum insulation material, composed of a core filling material and a vacuum protective surface layer. They effectively prevent heat transfer caused by air convection, thus significantly reducing the thermal conductivity. Furthermore, they contain no ODS materials, making them environmentally friendly and energy-efficient. They are currently the world's most advanced high-efficiency insulation material.

[0003] In existing insulated boxes, the insulation layer is usually made up of multiple independent vacuum insulation panels spliced ​​together. The drawback is that there are gaps between adjacent vacuum insulation panels, resulting in poor insulation performance of the insulated box. Utility Model Content

[0004] Based on the aforementioned problems in the prior art, one objective of this application is to provide an irregularly shaped vacuum insulation panel, which, by setting an irregularly shaped core material, produces an irregularly shaped vacuum insulation panel with a central panel and multiple outer expansion panels, with no gaps between the central panel and the outer expansion panels, thereby making the manufactured insulation box have good insulation performance.

[0005] The second objective of this application is to provide an insulated box.

[0006] The technical solution adopted by this application to solve its technical problem is: an irregularly shaped vacuum insulation panel, which is made by placing an irregularly shaped core material and an adsorbent in a barrier bag and vacuum heat-sealing it, including a middle panel and an outer expansion panel. The outer expansion panel is configured as a plurality of panels, the inner end of each outer expansion panel is connected to the middle panel, an indentation is formed at the connection position between the outer expansion panel and the middle panel, the side of each outer expansion panel is a side sealing edge, the side sealing edge lengths of two adjacent outer expansion panels are equal, an included angle is formed between two adjacent outer expansion panels, and the outer end of the outer expansion panel is an outer sealing edge.

[0007] Furthermore, the central plate is rectangular in shape.

[0008] Furthermore, the outer expansion plate is in the shape of an isosceles trapezoid, and the length of the inner end of the outer expansion plate is less than the length of the outer end of the outer expansion plate.

[0009] Furthermore, the angle between two adjacent outward expansion plates is less than ninety degrees.

[0010] Furthermore, the central plate is polygonal in shape.

[0011] Furthermore, the irregularly shaped core material is a centrifugal cotton core material, a chopped fiberglass felt core material, or an organic fiber core material.

[0012] Furthermore, the thickness of the irregular core material is 1mm-7mm, and the depth of the indentation is 1 / 3 to 2 / 3 of the thickness of the irregular core material.

[0013] Furthermore, the connection point of the adjacent two side edge lengths forms the first crease.

[0014] Furthermore, a second crease is formed at the connection point between the outer edge seal and the side edge seal.

[0015] The technical solution adopted by this application to solve its technical problem is: an insulated box, including an inner box, an insulation layer and an outer box, wherein the insulation layer is formed by folding the above-mentioned irregularly shaped vacuum insulation board, and the insulation layer is disposed between the inner box and the outer box.

[0016] The beneficial effects of this application are as follows: In use, each outward-expanding panel is folded upwards along the indentation, facilitating the connection of the side seals of adjacent outward-expanding panels. After the adjacent outward-expanding panels are connected, the irregularly shaped vacuum insulation board is folded to form an insulation layer, making it suitable for use in insulated boxes. Because the irregularly shaped core material and adsorbent are vacuum-sealed within a barrier bag, there are no gaps at the connection points between the outward-expanding panels and the central panel, resulting in a better insulation effect. Simultaneously, the side seals of adjacent outward-expanding panels can be bonded together, also eliminating gaps at the connection points. The indentation facilitates the upward folding of the outward-expanding panels along the indentation, forming a neat insulation layer. Attached Figure Description

[0023] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 4 As shown, this utility model discloses an irregularly shaped vacuum insulation panel, which is made by placing an irregularly shaped core material and an adsorbent in a barrier bag and then vacuum-sealing it. It includes a central panel 1 and an outer expansion panel 2. Multiple outer expansion panels 2 are provided. The inner end of each outer expansion panel 2 is connected to the central panel 1. An indentation 3 is formed at the connection position between the outer expansion panel 2 and the central panel 1. The side of each outer expansion panel 2 is a side sealing edge 21. The side sealing edges 21 of two adjacent outer expansion panels 2 are of equal length and form an included angle between two adjacent outer expansion panels 2. The outer end of the outer expansion panel 2 is an outer sealing edge 22.

[0025] Thus, the irregularly shaped vacuum insulation panel of this utility model, in use, involves folding each outward-expanding panel 2 upwards along the indentation 3, facilitating the connection of the side sealing edges 21 of adjacent outward-expanding panels 2 together. After the adjacent outward-expanding panels 2 are connected, the irregularly shaped vacuum insulation panel is folded to form an insulation layer, making it suitable for use in insulated boxes. Because the irregularly shaped core material and adsorbent are vacuum-sealed within a barrier bag, there are no gaps at the connection points between the outward-expanding panels 2 and the central panel 1, resulting in a better insulation effect. Simultaneously, the side sealing edges 21 of adjacent outward-expanding panels 2 can be connected by adhesive, again eliminating gaps at the connection points and further enhancing the insulation effect. The indentation 3 facilitates the folding of the outward-expanding panels 2 upwards along the indentation 3, forming a neat insulation layer.

[0026] like Figure 1 and Figure 2 As shown, in this embodiment, the central plate 1 is rectangular in shape. The outer expansion plate 2 is an isosceles trapezoid, and the length of the inner end of the outer expansion plate 2 is less than the length of the outer end. Thus, after the irregularly shaped vacuum insulation board is folded to form an insulation layer, the opening of the insulation layer gradually increases, thereby making the opening of the insulated box gradually larger, which facilitates the loading of items.

[0027] Furthermore, the two adjacent outer expansion plates 2 form an angle A, which is less than 90 degrees. In this way, insulation layers with gradually increasing openings of different shapes can be made according to requirements.

[0028] In some embodiments, such as Figure 4 As shown, the central plate 1 is polygonal in shape, such as pentagon or hexagon, so that different shapes of insulation layers can be made according to requirements.

[0029] In a preferred embodiment of this invention, the shaped core material is either centrifugal cotton core material or chopped fiberglass felt core material. After the vacuum insulation panel is manufactured, a pressing mechanism is used to press down the connection point between the central panel 1 and the outer expansion panel 2, thereby forming an indentation 3 at the connection point, which facilitates the folding of the central panel 1 through the indentation 3. Specifically, the thickness of the shaped core material used in this invention is 1mm-7mm, and the depth of the indentation is 1 / 3 to 2 / 3 of the thickness of the shaped core material. This facilitates the folding of the central panel 1 and the outer expansion panel 2 along the indentation 3, while also preventing heat leakage at the connection point between the central panel 1 and the outer expansion panel 2. The shaped core material can also be an organic fiber core material, mainly polyethylene terephthalate (PET) fiber with a diameter of 7-20 micrometers.

[0030] In this embodiment, the connection position of the lengths of adjacent side sealing edges 21 forms a first crease 4. When folding the irregularly shaped vacuum insulation panel, the side sealing edges 21 are coated or glued, and then folded along the first crease 4 to bond the adjacent side sealing edges 21 together.

[0031] In a preferred embodiment, a second crease 5 is formed at the connection point between the outer sealing edge 22 and the side sealing edge 21. The center of the second crease 5 is located at the corner of the core material. When folding the irregularly shaped vacuum insulation board, the connection point between the outer sealing edge 22 and the side sealing edge 21 is first folded outward along the second crease 5. Then, the outer sealing edge 22 is folded outward and glued to the outside of the barrier bag. Finally, the adjacent two side sealing edges 21 are glued together, and the side sealing edge 21 is folded outward and glued to the outside of the barrier bag, thus folding the irregularly shaped vacuum insulation board to form an insulation layer. By folding the connection point between the outer sealing edge 22 and the side sealing edge 21 outward along the second crease 5, the corner of the insulation layer formed after folding will not protrude, making it easier for the insulation layer to be placed between the inner and outer boxes.

[0032] This utility model also proposes an insulated box, which includes an inner box, an insulation layer, and an outer box. The insulation layer is formed by folding the aforementioned irregularly shaped vacuum insulation board and is disposed between the inner box and the outer box. By using an insulation layer formed by folding an irregularly shaped vacuum insulation board, after the insulation layer is installed between the inner box and the outer box, there is no gap at the connection between the outer expansion plate 2 and the middle plate 1 of the insulation layer, and there is also no gap at the connection between the two outer expansion plates 2, thereby improving the insulation effect of the insulated box.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
