本发明涉及一种保温包。The invention relates to a thermal insulation bag.
背景技术Background technique
保温包，属于户外箱包的一种，是用于装盛各种食物并保持食物温度和鲜度的包袋，其也可以用于冷藏，如可放入冰块、冷饮等低温物品，因此保热保冷是保温包最基本的功能。Insulation bag, a kind of outdoor luggage, is a bag used to hold various foods and keep food temperature and freshness. It can also be used for refrigeration, such as ice cubes, cold drinks and other low-temperature items, so it can be kept Heat preservation and cold preservation are the most basic functions of thermal insulation bags.
现有技术中，保温包一般具有保温层，保温层由内层布料和外层布料所包裹，在外层布料上还形成供拉链安装的半开口，半开口上方形成上盖，半开口下发形成依次由外侧、保温层和内侧围成的保温室，拉动拉链即可打开或关闭上盖，从保温室取物非常方便，目前保温层采用的保温材料一般有无纺布、铝膜珍珠棉、牛津布和涤纶等等。In the prior art, the thermal insulation bag generally has a thermal insulation layer, and the thermal insulation layer is wrapped by an inner layer of cloth and an outer layer of cloth, and a half opening for zipper installation is also formed on the outer layer of cloth, an upper cover is formed above the half opening, and a half opening is lowered to form a The insulation room is surrounded by the outside, insulation layer and inside in turn. Pull the zipper to open or close the upper cover. It is very convenient to take things from the insulation room. At present, the insulation materials used in the insulation layer generally include non-woven fabrics, aluminum film pearl cotton, Oxford cloth and polyester and so on.
对于一个具有优良保温性能的保温包来说，在采用保温层的基础上，保温室的密封性也是保温的关键，现有保温包内层布料和外层布料在开口处通过车缝的方式缝合，内层布料和外层布料也由若干小块布料缝合而成，而现有保温包还存在如下缺陷：For a thermal insulation bag with excellent thermal insulation performance, on the basis of the thermal insulation layer, the sealing of the thermal insulation room is also the key to thermal insulation. The existing thermal insulation bag inner layer fabric and outer layer fabric are sewn at the opening. , the inner layer of cloth and the outer layer of cloth are also stitched together by several small pieces of cloth, but the existing thermal insulation bag also has the following defects:
一、通过车线缝合的方式结合的内层布料和外层布料，其密封效果并不好，在缝合处留下针孔，内层布料与外层布料也不能完全的无缝结合，不可避免的降低了保温包的密封性，外部空气容易通过针孔或内外层间的缝隙与内部空气形成对流，导致保温包内部温度变化，保温效果不佳；1. The sealing effect of the inner fabric and the outer fabric combined by stitching is not good, and pinholes are left at the seams, and the inner fabric and the outer fabric cannot be completely seamlessly combined, which is inevitable The airtightness of the insulation bag is greatly reduced, and the external air is easy to form convection with the internal air through the pinhole or the gap between the inner and outer layers, resulting in the internal temperature change of the insulation bag, and the insulation effect is not good;
二、存放低温物品时（如冰块），出现了空气对流的情况下，冰块融化或空气冷凝，导致保温腔体内的水沿缝隙流至保温层从外层流出，此外内部的冷空气还可能造成外层的缝合处（特别是拉链开口处）出现水汽凝结的情况，上述情况均致使保温层使用寿命降低，而且内外层缝线老化易导致缝隙进一步扩大，降低保温包使用期限；2. When storing low-temperature items (such as ice cubes), in the case of air convection, the ice cubes melt or the air condenses, causing the water in the insulation cavity to flow from the outer layer along the gap to the insulation layer. In addition, the internal cold air is still It may cause water vapor condensation at the suture of the outer layer (especially at the opening of the zipper). The above situation will reduce the service life of the insulation layer, and the aging of the inner and outer sutures will easily lead to further expansion of the gap and reduce the service life of the insulation bag;
三，现有保温包的内侧与外层一般是在开口处直接缝合，内层布料在保温室上部的开口处的横截面远大于其在保温室底部的横截面，导致内侧布料出现褶皱的问题，而有些需要规整放置的保温物品不便放置。Three, the inner side and the outer layer of the existing heat preservation bag are generally directly stitched at the opening, and the cross section of the inner cloth at the opening of the upper part of the heat preservation room is much larger than its cross section at the bottom of the heat preservation room, resulting in the problem of wrinkles in the inner cloth , and some heat preservation items that need to be placed neatly are inconvenient to place.
有鉴于此，本发明人特别研制出一种实现完全密封保温室的保温包，本案由此产生。In view of this, the inventor specially developed a kind of heat preservation bag that realizes completely sealing heat preservation chamber, and this case arises from this.
