Description

一种带有可扩展保温层的背包 技术领域
本申请涉及背包技术领域，特别涉及一种带有可扩展保温层的背包。
背景技术
背包是生活中人们出行必不可少的装备，由于背包结构简单，便于携带，又能容纳许多生活品，因此，越来越多种类的背包不断出现，以适应人们在不同环境下的不同需求，现有技术中，背包仅仅体现出了单一功能，如容纳物品，又如中国专利CN203207412U，提供了一种折叠背包，包括一包体和一置物包，所述包体包括前壁、后壁和底部，前壁和后壁的中上部通过一拉锁连接，且前、后壁与底部缝合连接，包体后壁包括至少一肩带，肩带末端设置有钩扣，在包体底部边缘设置有条状拉链，在包体后壁中下部边缘至后壁中部设置与之对应的条状拉链；所述置物包包括顶部、底部，两侧壁、前壁和后壁，置物包后壁设置一对环形扣；所述置物包与包体通过包体底部连接为一体。本申请提供的折叠背包可以根据装入不同数量物品，展开或折叠收纳背包，根据情况选择大、小包，并且实现了背包和斜挎包、腰包、单肩包的转换。
上述专利的背包方便实用，但是，仅仅体现了容纳物品这一单一的特性，不能同时实现容纳物品并且对物品进行周期性保存的效果。
又如中国专利CN107878939A，公开了一种外卖配送箱，外卖配送箱包括：一个或多个保温箱；所述保温箱包括保温箱体和箱盖；所述保温箱体的内表面和箱盖内表面之间构成存放食物的空间；所述箱体的外表面为隔热防水层；所述箱体的内表面为导热防水层；所述箱体的内外表面之间构成储存水的空腔；所述箱体的上部设置有可密闭的用于输入热水或冰水或冰的进水口；所述箱体的下部设置有可密闭的出水口。本发明成本低廉，制造、使用方便，功能丰富，与现有的主流平台式外卖配送体系能够完成无缝融合，基本不会增加配送员或商户的经济或工作负担，且能够起到十分良好的效果。
上述保温箱尽管效果明显，并利于外卖食品的携带，并在周期内具有不错的效果，但是上述专利公开的保温箱结构较大，并且形状固定，不容易携带。
发明内容
本申请是鉴于上述问题作出的，通过提供一种带有可扩展保温层的背包，实现人们在需要时可以随身携带一些需要保温或冷藏的物品，也能够更加便携的提供该功能的目的，具体的，包括包身，所述包身包括正面侧、背面侧以及同时连接正面侧和背面侧的环面侧，其特征在于：所述环面侧与背面侧密封连接，所述环面侧与正面侧通过拉链啮合连接，所述拉链打开时，在包身上靠近正面侧的一侧形成背包开口，所述背包开口的面积大于1/2正面侧端面的面积；
所述环面侧的左右两端分别形成为包身的左侧面和右侧面，所述左侧面或右侧面上设有侧向拉链，打开所述侧向拉链使环面侧上形成侧向开口；
所述包身内部靠近所述侧向开口一侧的环面侧上设有与开口连接的保温部，所述保温部由布袋包裹而成且为可伸缩的管状保温部，所述保温部的内壁上设有保温层。
具体的，上述结构的背包，通过设置保温部使用户在使用时，能够根据需要放置一些在一定周期内需要保温或冷藏的物品，而通过侧向开口将物品从背包的侧面放置进入包身，能够使用户能加便携的拿取，不必每一次都开打背包的背包开口，另外背包开口的大小结构也进一步的配合了该背包能够实现内部容纳效果的目的，该大小结构的设计在用户将物品放入保温部后，能从较大的背包开口处对放置的物品进行摆放，提升了背包使用便携效果。
上述结构的保温部通过管状结构实现了一定的容纳空间，管状为保温部的优选设计，其他形状的设计也是可以的，而保温层的设计是使保温部产生保温或冷藏效果的基础结构。
优选的，所述保温部设在靠近包身底部一侧的环面侧上，所述保温部的底面与包身底面相贴。
具体的，上述结构的保温部位置位于背包的底部，这样的效果是保温部内部放置的物品能够通过背包的底端面进行支撑，保证了保温部内部物品的正常存放。同时该位置也保证了保温部结构的稳定性。
优选的，所述保温部收缩时紧贴所述左侧面或右侧面的内壁，所述保温部展开时其管状的纵向轴距大于1/2背包宽度的距离。
具体的，上述结构的保温部，在收缩时，不会占用包身内部的空间，使用户在不需要进行保温或冷藏时能得到更大的背包内部空间进行容纳，而在使用保温部使，将其展开，这样的结构为使用者提供了不同的选择，提升了背包的便携效果，而保温部展开后的宽度 设计为优选的方案，该方案为客户提供了具有一定容积的管状保温部。同时，如果管状轴向直径太短就会造成背包内部其他物品对保温部的过度压力，造成保温部内的物品被挤压的状况，而本方案中的保温部在其轴向上的距离能避免前述情况的发生。
优选的，所述保温部展开后的高度小于所述包身高度的1/2。
具体的，上述结构的保温部，其高度为最优的方案，其他高度方案也可行，但是在普通背包中，需要被冷藏或保温的物品并不需要很多，也不会占用整个背包的空间，并且背包中还需要放置一些其他物品，因此本技术方案中的保温部的高度(管状保温部的直径)，为比较实用而且便携的方案。
优选的，靠近所述正面侧方向的所述左侧面和右侧面的上方边缘，向靠进背面侧的方向收缩形成固定弧边缘，所述正面侧通过拉链与左侧面和右侧面啮合连接时，所述正面侧的下半部分为纵向直面，上半部分向所述背面侧倾倒形成倾斜弧面。
具体的，上述结构的左侧面和右侧面的结构，能够固定背包的整体形状，在背包的上半部分形成容积收缩状的包身，这样的结构一方面提升了包身整体的美观效果，另一方面，在包身上半部分收缩以减小包身内部的容积，能够使放置在包身内部上方的物品能够通过正面侧进行压紧，不会因晃动，使包身内部位于上方的物品滑落至下方，导致背包变形，内部物品堆叠。
优选的，所述正面侧的边缘上设有U字型拉带，所述左侧面和右侧面上设有与所述U字型拉带互相啮合的对应拉带，所述U字型拉带上设有双向拉头，用于从不同方向打开背包。
具体的，上述结构的拉带，设置了双向拉开的拉头，一方面上述拉链结构实现了背包开口的面积大于1/2正面侧端面的面积的目的，使用户使用更方便，另一方面，上述U字型拉带在包身上为倒置状态，这样才使背包开口朝上。
优选的，所述侧向开口上设有上开口和下开口，所述上开口设在所述左侧面或右侧面的中部，所述上开口沿同时靠近背面侧和包身底部的方向延伸至环面侧的边缘，所述下开口沿靠近背面侧的方向延伸至环面侧的边缘，所述上开口和下开口在靠近背面侧方向的环面侧边缘连通形成侧向开口。
具体的，上述结构的侧向开口设计，能够使用户更加方便的通过侧向开口放置物品，同时上开口和下开口的组合状态能够使用户从上方或下方分别拿取物品，提升了背包的便携效果，并且侧向开口朝向背面侧，因此具有一定的防盗效果，更加安全。
优选的，所述上开口和下开口处分别设有拉头，使所述侧向开口可自上开口处或下开口处打开。
具体的，上述结构的拉头，是打开或闭合侧向开口的方式多样化，进而配合用户通过侧向开口拿取背包内部的物品。
优选的，与所述侧向开口位置相对的包身另一侧的环面侧上设有与所述侧向开口结构一致的反向开口，所述反向开口内形成为容纳层。
具体的，上述结构的反向开口，一方面提供了与侧向开口一致的结构，提升了背包整体美观性，另一方面，该反向开口可以容纳一些需要及时取用的物品，结构简单方便，使用效果好。
