Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.
An insulation pack according to a first embodiment of the utility model will be described with reference to figures 2 to 5, in which the insulation pack employs a vacuum insulation panel VIP in combination with the insulation pack shown in figure 1, and more particularly with an EPE insulation layer. Specifically, the thermal insulation pack 10 includes a pack body 11 for accommodating articles (e.g., various foods) and an upper cover 12 for covering the pack body 11. The pack body 11 comprises an inner container 111 having four side walls (two of which are shown in cross-section in the drawings) and a bottom wall, and the outside of the side walls and the bottom wall are covered by a first inner TPU fabric layer 13 and a second outer TPU fabric layer 14. The upper cover 12 includes an upper cover body 121, and the outside of at least a portion of the upper and side portions of the upper cover body is covered with a first inner TPU fabric layer 13 and a second outer TPU fabric layer 14. When the upper cover 12 covers the bag main body 11, the whole thermal insulation bag is covered by the TPU fabric layer. Between the first inner TPU fabric layer 13 and the second outer TPU fabric layer 14, in addition to the EPE insulation layer 15 shown in fig. 1, a vacuum insulation panel 16 and a protective layer 17 for protecting the vacuum insulation panel 16 are interposed. By introducing Vacuum Insulation Panels (VIP) with good insulation properties and forming a combined structure with EPE insulation, allowing further improvement of insulation capacity; and the life span of the insulation pack according to the present invention is ensured by providing a protective layer for protecting the vacuum insulation panel, i.e., preventing the vacuum insulation panel from being excessively deformed and/or broken and failed due to an external force, for example, being pierced by a sharp object such as a stone or a projection on the ground or being pressed by a heavy object when used outdoors.
For the first embodiment of the insulation pack, it should be understood that vacuum insulation panels may be selectively introduced between the first inner TPU fabric layer and the second outer TPU fabric layer to form a composite structure with the EPE insulation layer. For example, the vacuum insulation panel may be introduced between a first inner TPU fabric layer and a second outer TPU fabric layer for the sidewall of the inner bladder, or between a first inner TPU fabric layer and a second outer TPU fabric layer for the bottom wall of the inner bladder, or between a first inner TPU fabric layer and a second outer TPU fabric layer for the upper cover, or between a first inner TPU fabric layer and a second outer TPU fabric layer for both or three of them.
In a first embodiment as shown in fig. 2, the EPE insulation layer 15, the vacuum insulation panel 16 and the protective layer 17 are arranged between the first inner TPU fabric layer 13 and the second outer TPU fabric layer 14 in the following manner: the vacuum insulation panel 16 is adjacent to the first inner TPU fabric layer 13 followed by the EPE insulation layer 15 and the protective layer 17 is adjacent to the second outer TPU fabric layer 14. In assembly, the vacuum insulation panel 16 may be bonded to the inside of the EPE insulation layer 15 and the protective layer 17 may be bonded to the outside of the EPE insulation layer 15, so that the three are simultaneously inserted together between the first inner TPU fabric layer 13 and the second outer TPU fabric layer 14. By being bonded to each other, not only can assembly be facilitated, but also the fixation of the layers between the TPU fabric layers can be further facilitated. Alternatively, in a variant (not shown), the protective layer 17 may be arranged adjacent to the vacuum insulation panel 16, i.e. the vacuum insulation panel 16, the protective layer 17 and the EPE insulation layer 15 are arranged in sequence from the first inner TPU fabric layer 13 to the second outer TPU fabric layer 14.
A second embodiment of the thermal pack according to the utility model is described with reference to fig. 3 and also with reference to fig. 2, in particular with reference to the exemplarily shown protective layer 17 and its position. An EPE thermal insulation layer 15, a vacuum thermal insulation board 16, an EPE thermal insulation layer 15 and a protective layer 17 are sequentially arranged from the first inner TPU fabric layer 13 to the second outer TPU fabric layer 14. In a variant (not shown), the protective layer 17 may be provided adjacent to the vacuum insulation panel 16.
A third embodiment of an insulation pack according to the utility model is described with reference to fig. 4 and also with reference to fig. 2, in particular with reference to the exemplarily shown protective layer 17 and its position. An EPE insulation layer 15, a vacuum insulation panel 16 and a protective layer 17 are sequentially arranged from the first inner TPU fabric layer 13 to the second outer TPU fabric layer 14.
A fourth embodiment of the thermal pack according to the utility model is described with reference to fig. 5 and with reference to fig. 2 in particular to the exemplarily shown protective layer 17 and its position. A vacuum insulation panel 16, an EPE insulation layer 15, a vacuum insulation panel 16 and a protective layer 17 are sequentially arranged from the first inner TPU fabric layer 13 to the second outer TPU fabric layer 14.
A thermal bulb according to a second embodiment of the utility model will be described with reference to fig. 6 and with reference to fig. 2 in particular to the exemplarily shown protective layer 17 and its position. The insulation pack of this second embodiment is substantially similar in general structure to the insulation pack of the first embodiment described above, except that only the vacuum insulation panel 16 and the protective layer 17 are arranged in sequence from the first inner TPU fabric layer 13 to the second outer TPU fabric layer. In this embodiment, a vacuum insulation panel and a protective layer can be arranged between the first inner TPU fabric layer and the second outer TPU fabric layer for the inner container side wall and the inner container bottom wall and the upper cover body to ensure the insulation performance.
In addition to vacuum insulation panels having an integral fill layer with a relatively large surface area, insulation packs according to the present invention may also be used with vacuum insulation panels having a plurality of relatively small surface area fill modules 161 as schematically illustrated in figure 7. Specifically, these smaller surface area filler modules 171 are arranged in spaced apart relation to one another within the vacuum insulation panel. Compared with an integral filling layer with a larger surface area, the structure that the plurality of filling modules are arranged in a certain gap arrangement mode can have better bending deformation resistance, and the failure of the whole vacuum insulation panel can not be caused even if the vacuum insulation panel is partially damaged, so that the heat insulation effect and the service life of the heat insulation bag can be further ensured.
The protective layer in the insulation pack according to the present invention is a structure capable of protecting the vacuum insulation panel between the vacuum insulation panel and the outer TPU fabric layer to prevent it from being excessively deformed and/or failing by external force, and may be, for example, a metal plate (such as an iron plate or a steel plate), a wood plate, a hard plastic plate, or the like.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation configuration and operation, and thus, should not be construed as limiting the present invention.
Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. Thus, a definition of "a first" or "a second" feature may explicitly or implicitly include one or more of the features.
Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and those skilled in the art can make combinations, changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention.
