Description

一种双层方形保温容器
技术领域
本实用新型涉及模具技术领域，尤其是涉及一种双层方形保温容器。
背景技术
现有的双层真空保温桶是通过内外不锈钢焊接，内胆和外壳之间通过真空炉，抽去中间空气，形成内侧真空层。真空层隔断内部与外部的热传导，从而起到保温保冷。由于大气压力，内外不锈钢需要保持一定强度，才能保证不被压瘪。通过物理原理可知，圆弧面各方位的支撑力均匀分布，保证真空层不被吸憋相对比较简单。而现有的方形桶，周边四个面都是平面，四个角圆弧过渡，就会造成整个面受力不均衡：四个角支撑力较强，平面支撑力较弱，从而使平面中间下凹，既影响整体美观，又影响真空效果。
通常市面上采用增加材料厚度解决上述问题，但是这样既增加了成本，也增加容器本体的重量，影响客户体验感和市场竞争力。
实用新型内容
为克服现有技术缺点，本实用新型目的在于提供一种双层方形保温容器，以解决上述背景技术中提到的问题。
为实现上述目的，本实用新型采用以下技术方案：
一种双层方形保温容器，包括容器本体，所述容器本体整体呈长方体，容器本体由内胆和外壳组成，内胆和外壳之间设有真空层，内胆和外壳的侧壁上均设有加强筋，所述加强筋能够使方形容器的表面在抽真空时受力均衡，从而避免吸憋现象。
优选的，所述外壳的厚度在0.48～0.60mm之间。
更优选的，所述内胆的厚度在0.45～0.55mm之间。
更优选的，所述加强筋的高度在1.5～2.2mm之间。
优选的，所述外壳的桶口处设有桶口加强筋，所述桶口加强筋设于外壳桶口的两相对侧壁上，以免抽真空时变形。
更优选的，所述桶口加强筋的支撑面互相垂直。
优选的，所述内胆和外壳的底部也均设有加强筋。
优选的，所述外壳通过焊接固定设于内胆外，外壳与内胆的焊接点为桶口一周。
更优选的，所述外壳底部设有真空孔。
与现有技术相比，本实用新型的有益效果如下：
本实用新型通过在模具表面增加加强筋，加强筋的高度设为1.5～2.2mm左右时(1mm没有效果，3mm成型后不美观)，使方形的表面受力均衡，从而避免吸憋现象；且经过反复试验得到内胆外壳的厚度只要0.5mm左右，从而使得方桶重量大大减轻。在方桶的四周和底面，增加不同形状的加强筋，既保证了钢壁的支撑力，又增加外观效果。
附图说明
为了更清楚地说明本实用新型实施例的技术方案，下面将对实施例描述所需要使用的附图作简单介绍，显而易见，下面描述中的附图仅仅是本实用新型的一些实施例，对本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本实用新型实施例的整体结构示意图。
图2为本实用新型实施例的外壳底部的结构示意图。
图3为本实用新型实施例的一侧壁的结构示意图。
图4为本实用新型实施例的另一侧壁的结构示意图。
图中，各附图标记为：
1-真空层；2-容器本体；3-桶口加强筋；4-外壳底部；41-真空孔；5-桶口； 6-加强筋；7-侧壁；8-焊接点。
具体实施方式
为了更清楚地说明本实用新型，下面结合实施例并对照附图对本实用新型作进一步详细说明。本领域技术人员应当理解，下面所具体描述的内容是说明性的而非限制性的，不应以此限制本实用新型的保护范围。
在本实用新型的描述中，需要说明的是，术语“内”、“外”、“上”、“下”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本实用新型和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本实用新型的限制。此外，除非另有明确的规定和限定，术语“安装”、“连接”等应做广义理解，例如，可以是固定连接，可以是可拆卸连接，也可以是一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，可以通过中间媒介间接相连，也可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本实用新型中的具体含义。
实施例：
如图1-4所示的一种双层方形保温容器，包括容器本体2，容器本体2整体呈长方体，容器本体2由内胆和外壳组成，外壳底部4设有真空孔41，内胆和外壳之间设有真空层1，外壳通过焊接固定设于内胆外，外壳与内胆的焊接点8 为桶口一周。内胆和外壳的侧壁7上均设有加强筋6，加强筋6能够使方形容器的表面在抽真空时受力均衡，从而避免吸憋现象。外壳的桶口5处设有桶口加强筋3，桶口加强筋3设于外壳桶口的两相对侧壁7上，以免抽真空时变形；桶口加强筋3的支撑面必须互相垂直，即支撑面倾斜会导致侧壁7受力，大大缩小了支撑强度，本实施例中桶口加强筋3为三角形加强筋，两直角边分别在桶口5 侧壁、桶口5与侧壁7的厚度差平台上；内胆和外壳的底部也均设有加强筋6。
外壳的厚度在0.48～0.60mm之间，内胆的厚度在0.45～0.55mm之间，加强筋 6的高度在1.5～2.2mm之间，经过反复试验得到内胆外壳的厚度只要0.5mm左右，可以使得方桶重量大大减轻。本实施例中，内胆和外壳的厚度均为0.5mm，此时加强筋6的高度设为2mm，经试验加强筋6选用1mm时没有效果，选用3mm时成型后不美观。
图3为本实施例提供的一种侧壁7的加强筋6的设置方式，图4为另一种加强筋6的设置方式，加强筋6的具体设置方式可根据不同需求自行调整；本实施例中的容器本体2的内胆和外壳均采用食品级不锈钢制成，容器本体2的四周和底面增加不同形状的加强筋6，既保证了钢壁的支撑力，又增加外观效果。
显然，本实用新型的上述实施例仅仅是为更清楚地说明本实用新型所作的举例，而并非是对本实用新型的实施方式的限定，对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其他不同形式的变化或变动，这里无法对所有的实施方法予以穷举，凡是属于本实用新型的技术方案所引申出的显而易见的变化或变动仍处于本实用新型的保护范围之列。
