为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合附图对本发明的各实施方式进行详细的阐述。然而，本领域的普通技术人员可以理解，在本发明各实施方式中，为了使读者更好地理解本申请而提出了许多技术细节。但是，即使没有这些技术细节和基于 以下各实施方式的种种变化和修改，也可以实现本申请所要求保护的技术方案。
在下文的描述中，出于说明各种公开的实施例的目的阐述了某些具体细节以提供对各种公开实施例的透彻理解。但是，相关领域技术人员将认识到可在无这些具体细节中的一个或多个细节的情况来实践实施例。在其它情形下，与本申请相关联的熟知的装置、结构和技术可能并未详细地示出或描述从而避免不必要地混淆实施例的描述。
除非语境有其它需要，在整个说明书和权利要求中，词语“包括”和其变型，诸如“包含”和“具有”应被理解为开放的、包含的含义，即应解释为“包括，但不限于”。
以下将结合附图对本发明的各实施例进行详细说明，以便更清楚理解本发明的目的、特点和优点。应理解的是，附图所示的实施例并不是对本发明范围的限制，而只是为了说明本发明技术方案的实质精神。
在整个说明书中对“一个实施例”或“一实施例”的提及表示结合实施例所描述的特定特点、结构或特征包括于至少一个实施例中。因此，在整个说明书的各个位置“在一个实施例中”或“在一实施例”中的出现无需全都指相同实施例。另外，特定特点、结构或特征可在一个或多个实施例中以任何方式组合。
如该说明书和所附权利要求中所用的单数形式“一”和“所述”包括复数指代物，除非文中清楚地另外规定。应当指出的是术语“或”通常以其包括“和/或”的含义使用，除非文中清楚地另外规定。
在以下描述中，为了清楚展示本发明的结构及工作方式，将借助诸多方向性词语进行描述，但是应当将“前”、“后”、“左”、“右”、“外”、“内”、“向外”、“向内”、“上”、“下”等词语理解为方便用语，而不应当理解为限定性词语。
下文参照附图描述本发明的实施例保温容器，如图1至图4所示，保温容器包括箱体10，箱体10包括：内胆1、外壳2和保温层3，其中，内胆1具有内底板11和从内底板11的外周往上延伸的内侧板12，外壳2套设在内胆1的外周并具有从外底板21的外周往上延伸的外侧板22。内底板11与外底板21之间相互间隔开，以及各内侧板12与各自相对的外侧板22之间均间隔开，从而在内胆1和外壳2之间形成空腔4，保温层3设置在该空腔4内，由于内胆1与外壳2之间相互独立，内胆1可以一体成型也可以由多块板材拼接而成，外壳2也可以一体成形或者由多块板材拼接而成，内胆1与外壳2之间不会大面积存在不适合放置保温层3的区域，因此保温层3基本可以覆盖整个内胆1，也就是能够包裹住整个保温容器的置物腔13，从而可以有效提高保温箱保温性能。
另外，优选的，如图3和图4所示，内胆1的相邻两个内侧板12之间拐角处16的外表面也被保温层3覆盖，同时，优选的，各内侧板12与内底板11之间拐角处16的外表面也 被保温层3覆盖，这样还能够保证拐角处16也是被覆盖的，从而进一步提高保温箱的保温性能。
另外，优选的，如图2所示，内胆1内具有置物腔13，内胆1界定置物腔13的区域均与外壳2相互隔开至少预设距离以填充保温层3，因此保温层3可以完全覆盖整个置物腔13，以保证置物腔13内的温度。
具体的，如图3和图4所示，在本实施例中，保温层3为固态板材，在实际情况中，可以先将内胆1和外壳2制作好，将保温层3一块一块地完全包覆于内胆1的外表面，再将内胆1连同保温层3放入外壳2内，再将内胆1和外壳2的上端封闭在一起即可，在有些实施例中，例如可以采用封条密封内胆1和外壳2的上端面。但在本实施例中，如图3所示，各外侧板22远离外底板21的一端也就是各外侧板22的上端均朝箱体10外延伸形成一圈外檐23，各内侧板12远离内底板11的一端也就是各内侧板12的上端均朝箱体10外延伸形成一圈内檐14，当内胆1放置于外壳2内的时候，内檐14靠近靠近端部的一端位于外檐23上方，并且与外檐23重合，此时可以将内檐14和外檐23胶粘或焊接在一起。
当然，在有些实施例中，也可以将先内胆1放置在外壳2内，内胆1与外壳2之间形成上述空腔4，然后再将保温层3塞入空腔4内。
另外，在有些实施例中，保温层3还可以是非固态的，例如保温层3的材料可以是保温发泡剂或者液体保温材料，例如，可以采用聚氨酯发泡剂，还可以采用例如公开号为CN1093391A的专利中所示的液体保温隔热材料，当保温层3为非固态时，应当先将内胆1放入外壳2内，在内胆1与外壳2之间形成空腔4，再将非固态的保温层3灌入空腔4内，再将内胆1与外壳2的上端密封住，例如可以将内檐14与外檐23焊接在一起，使得空腔4内形成密闭腔体。
另外，如图3所示，外檐23和内檐14的端部均朝下延伸一段距离，这样内檐14和外檐23还可以形成一个把手，方便使用者搬运保温容器。
如图4所示，外壳2的外底板21还具有朝箱体10外凸出的支撑部24，通过该支撑部24可以支撑整个箱体10，具体的，支撑部24可以是外设的，也可以是由外壳2的外底板21朝远离箱体10内的方向凸出形成的，在本实施例中，支撑部24为沿外底板21边缘设置的一圈凸棱。当然，在有些实施例中，支撑部24也可以是多个凸起，各凸起分别在外底板21上。
另外，如图5和图6所示，箱体10还包括隔板7，隔板7可操作地将箱体10内的空间分隔成两个区域，箱体10的内胆1有部分朝箱体10内凸出形成一对隔板7限位部15，一对隔板7限位部15相对设置于隔板7两侧，并均与隔板7卡接。具体的，如图7所示，一对 隔板7限位部15中的每个隔板7限位部15包括：均沿箱体10的高度方向延伸的一对肋条151，一对肋条151沿垂直于箱体10的高度方向相互隔开形成卡接区，隔板7任意一侧边缘位于该卡接区内。由于隔板7限位部15是有内胆1往箱体10内凸出形成的，因此在内胆1成形的过程中，例如注塑成形过程中，就可以将隔板7限位部15一体成形了，从而提高了箱体10的制造便利性，同样的，在外壳2成形过程中，例如注塑成形过程中，还可以将支撑部24一体成形了。
另外，如图5和图6所示，各所述内侧板12和各所述外侧板22均沿自上而下逐渐往所述箱体10内倾斜。也就是整个箱体10的横截面时自上而下逐渐缩小的，这样一个箱体10的下段就可以放入另一个箱体10内，从而方便箱体10的收纳。
如图2、图3和图8所示，保温容器还包括箱盖5，箱盖5盖合于箱体10的开口上，箱盖5包括：内板51和外板52，其中，外板52与内板51相对设置；外板52的外圈与内板51的外圈固定连接，例如胶粘或者焊接在一起。外板52的中间区域与内板51相互隔开形成保温腔53，箱盖5还包括位于保温腔53内的绝热层54。
另外，内板51有部分朝远离外板52方向凸出形成用于悬挂蓄冷板6的悬挂部。如图8至图10所示，悬挂部包括：相对设置于蓄冷板6两侧的第一凸出部55和第二凸出部56，蓄冷板6位于第一凸出部55和第二凸出部56之间；其中，第一凸出部55的端部朝第二凸出部56方向延伸，该第一凸出部55延伸的部位位于蓄冷板6远离外板52的一侧，第二凸出部56的端部朝第一凸出部55的方向延伸，该第二凸出部56延伸的部位位于蓄冷板6远离外板52的一侧。这样第一凸出部55和第二凸出部56就形成了一个两个挂钩，钩住蓄冷板6，从而可以固定住蓄冷板6，需要拆卸蓄冷板6时，只需要将蓄冷板6从第一凸出部55和第二凸出部56之间拉出来即可。
本发明实施例还提供了一种保温容器的制造方法，具体制造方法如下：
采用均上述实施例中的内胆1和外壳2，所述内底板11与所述外底板21之间以及各所述内侧板12与各自相对的所述外侧板22之间均间隔开，在所述内胆1和所述外壳2之间形成空腔4；将绝热层54设置于所述空腔4内。
具体的，可以先将内胆1和外壳2制作好，将绝热层54一块一块地完全包覆于内胆1的外表面，再将内胆1连同绝热层54放入外壳2内，再将内胆1和外壳2的上端封闭在一起即可。也可以先将内胆1放入外壳2内，在内胆1与外壳2之间形成上述空腔4，再将绝热层54放入空腔4内，再将内胆1与外壳2的上端密封住。
具体的，如图3所示，各所述外侧板22远离所述外底板21一端均往所述箱体10外延伸形成一圈外檐23，各所述内侧板12远离所述内底板11一端均往所述箱体10外延伸形成 一圈内檐14；在将保温层3设置于所述空腔4内之后，连接所述外檐23与所述内檐14，例如可以将内檐14和外檐23胶粘或焊接在一起。
以上已详细描述了本发明的较佳实施例，但应理解到，若需要，能修改实施例的方面来采用各种专利、申请和出版物的方面、特征和构思来提供另外的实施例。
考虑到上文的详细描述，能对实施例做出这些和其它变化。一般而言，在权利要求中，所用的术语不应被认为限制在说明书和权利要求中公开的具体实施例，而是应被理解为包括所有可能的实施例连同这些权利要求所享有的全部等同范围。
上面各种方法的步骤划分，只是为了描述清楚，实现时可以合并为一个步骤或者对某些步骤进行拆分，分解为多个步骤，只要包括相同的逻辑关系，都在本专利的保护范围内；对算法中或者流程中添加无关紧要的修改或者引入无关紧要的设计，但不改变其算法和流程的核心设计都在该专利的保护范围内。
不难发现，第二个实施方式为与第一个实施方式相对应的方法实施例，第二个本实施方式可与第一个实施方式互相配合实施。第一个实施方式中提到的相关技术细节在第二个实施方式中依然有效，为了减少重复，这里不再赘述。相应地，第二个实施方式中提到的相关技术细节也可应用在第一个实施方式中。
本领域的普通技术人员可以理解，上述各实施方式是实现本发明的具体实施例，而在实际应用中，可以在形式上和细节上对其作各种改变，而不偏离本发明的精神和范围。
