Technical Field

[0001] The utility model relates to the technical field of non-woven bags, in particular to a heat-insulating non-woven bag. Background Art

[0002] At present, non-woven bags are often used in various fields, such as daily shopping bags for people, or combined with insulation layers to be used in takeout and catering industries, such as milk tea delivery bags, lunch bags or delivery bags for takeout staff.

[0003] At present, some lunch bags that combine an insulation layer with a non-woven fabric layer, or delivery bags used by deliverymen to carry takeout, have a structure in which the non-woven fabric layer and the insulation layer are fixedly connected by sewing. The inconvenience of this structure is that bumps are inevitable in the process of deliverymen transporting food, so food soup may occasionally leak out. However, the residue at the seams between the non-woven fabric layer and the insulation layer is generally difficult to clean. After being left for a long time, it is easy to ferment and deteriorate, which is not conducive to food hygiene. Utility Model Content

DETAILED DESCRIPTION

[0021] The following is a combination of the appended examples of the present invention Figure 1-4 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] Example:

[0023] like Figures 1 to 4 As shown, the utility model discloses a thermal insulation non-woven bag, comprising a bag body 1 with an upward opening and a thermal insulation liner 2, wherein the thermal insulation liner 2 comprises a thermal insulation bottom sheet 21 and a thermal insulation enclosure 22, and an anti-overflow enclosure 211 extends upward around the thermal insulation bottom sheet 21, and the upper end of the anti-overflow enclosure 211 is used to be detachably connected to the lower end of the thermal insulation enclosure 22. At the same time, the upper end edge of the thermal insulation enclosure 22 is detachably connected to the opening edge of the bag body 1.

[0024] Through this structure, when people find dirt inside the bag body 1, they can remove the thermal insulation film 21 and the thermal insulation enclosure 22 for cleaning. If it is some dirt that has accumulated over the years and is very difficult to clean, the thermal insulation film 21 or the thermal insulation enclosure 22 can be directly replaced.

[0025] The anti-overflow fence is actually a part of the thermal insulation bottom sheet 21, which is formed by folding the outer peripheral area of ​​the thermal insulation bottom sheet 21. The thermal insulation bottom sheet 21 is provided with a folding mechanism, which is used to fold the outer periphery of the thermal insulation bottom sheet 21 to form the anti-overflow fence 211. Specifically:

[0026] like Figure 3 and Figure 4As shown, the base surface of the thermal insulation bottom sheet 21 is a square. At the same time, the folding mechanism includes a first easy-folding line 212 and a second easy-folding line 213 with square and "V"-shaped outlines respectively, wherein the first easy-folding line 212 is formed by equidistantly reducing the outer outline of the thermal insulation bottom sheet 21, and the second easy-folding line 213 is arranged between the first easy-folding line 212 and the outer edge of the thermal insulation bottom sheet 21. Four second easy-folding lines 213 are evenly arranged on the thermal insulation bottom sheet 21 in the circumferential direction, and one side of the second easy-folding line 213 coincides with the diagonal line of the thermal insulation bottom sheet 21 and the other side is perpendicular to the outer peripheral edge of the thermal insulation bottom sheet 21.

[0027] In addition, a fixing mechanism for fixing the anti-overflow enclosure 211 structure is provided on the thermal insulation base sheet 21. The fixing mechanism includes four groups of snap fasteners evenly distributed along the circumference on the thermal insulation base sheet 21. Each group of snap fasteners includes a first sub-snap 214 and a first female snap 215. In this structure, the first sub-snap 214 and the first female snap 215 are arranged on the same side base surface of the thermal insulation base sheet 21 and are respectively located on the inner and outer sides of the second easy-folding line 213.

[0028] A plurality of second male buckles 216 and second female buckles 221 are respectively provided on the thermal insulation bottom sheet 21 and the thermal insulation enclosure 22 .

[0029] A zipper 11 for detachable connection is provided between the anti-overflow enclosure 211 and the bag body 1 .

[0030] The installation method of this structure is: first, the bottom film is folded by the first sub-button 214 and the second sub-button 216 to form an anti-overflow enclosure 211, and then the thermal insulation enclosure 22 is combined with the anti-overflow enclosure 211, and finally the anti-overflow enclosure 211 is installed on the bag body 1. During use, if soup is poured out, the anti-overflow enclosure 211 and the thermal insulation bottom film 21 are used to hold this part of the soup. At the same time, since there is an overlapping area between the anti-overflow enclosure 211 and the thermal insulation enclosure 22, the soup can be prevented from contacting the bag body 1. When cleaning is required, the zipper 11 can be opened first to separate the bag body 1 from the thermal insulation liner 2, and then the thermal insulation bottom film 21 can be removed from the thermal insulation enclosure 22 and the thermal insulation bottom film 21 can be unfolded, and then the thermal insulation bottom film 21 and the thermal insulation enclosure 22 can be cleaned.

[0031] It should be noted that the specific amount of soup pouring that this structure can handle is determined by the height of the heat-insulating enclosure 22.

[0032] It should also be pointed out that the terms indicated in the present invention, such as: "front", "rear", "vertical", "horizontal", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as limiting the scope of protection of the present invention.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
