Abstract

一种长扁型饭盒,具有底部、盒壁和边缘,在所述边缘之下的盒壁上具有台阶面,其特征在于,所述台阶面做成抗弯曲应力的弧形。长型的边缘中间部分容易受到较大的弯曲应力影响,对于吸塑类的饭盒在定型后容易变形,本实用新型利用一个弧度弯曲方向与饭盒变形方向相反的台阶面来抵消弯曲应力带来的变形,有效克服了在吸塑饭盒中容易产生的边缘变形。

Description

长扁型饭盒
【技术领域】
本实用新型涉及民生日常用品,尤其涉及用于食物包装的一次性饭盒。 
【背景技术】
快餐盒用于包装食物方便携带,是日常生活中经常使用的物品,现在市面上的快餐盒种类和型号很多,可以满足不同的场合使用需要,快餐盒质量不好或者结构设计不够合理会给使用带来很多不便,通常饭盒有圆形或者长型,或者呈现盘状的扁型,现有一种竖直边缘浅,长型的饭盒,由于这种类型的饭盒边缘很浅,就不太方便做出加强筋,而从力学角度来说,由于边比较长,中间部位的弯曲应力比较大,能容易导致饭盒边缘部分弯曲变形,特别是吸塑类的饭盒,在定型后边缘向下塌陷,构成明显弯曲,影响使用。 
【发明内容】
本实用新型针对以上问题提出了一种具有防弯曲结构的长扁型饭盒,能克服饭盒边缘弯曲形变,不影响使用。 
本实用新型的技术方案是:一种长扁型饭盒,具有底部、盒壁和边缘,在所述边缘之下的盒壁上具有台阶面,其特征在于,所述台阶面做成抗弯曲应力的弧形。 
所述弧形台阶面向上拱起。 
在所述边缘长度方向制作出两个弧形台阶面,防止单个台阶面受力不够均匀。 
本实用新型的效果:长型的边缘中间部分容易受到较大的弯曲应力影响,对于吸塑类的饭盒在定型后容易变形,本实用新型利用一个弧度弯曲方向与饭盒变形方向相反的台阶面来抵消弯曲应力带来的变形,有效克服了在吸塑饭盒中容易产生的边缘变形。 
【附图说明】
图1是本实用新型一实施例结构示意图。 
  其中:1、底部;2、盒壁;3、边缘;4、台阶面。 
【具体实施方式】
为了使本实用新型的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本实用新型进行进一步详细说明。 
实施例1:一种长扁型饭盒,具有底部1、盒壁2和边缘3,在所述边缘3之下的盒壁2上具有台阶面4,其特征在于,所述台阶面4做成抗弯曲应力的弧形。 
所述弧形台阶面4向上拱起,因为边缘是受弯曲应力而下陷,所以抵消弯曲应力的台阶面4弧形向上拱起,与之方向相反。 
在所述边缘长度方向制作出两个弧形台阶面4,防止单个台阶面受力不够均匀。 
对于特定结构的饭盒,可以在饭盒宽度方向上也制作出防止形变的台阶面。 
本实用新型的效果:长型的边缘中间部分容易受到较大的弯曲应力影响,对于吸塑类的饭盒在定型后容易变形,本实用新型利用一个弧度弯曲方向与饭盒变形方向相反的台阶面来抵消弯曲应力带来的变形,有效克服了在吸塑饭盒中容易产生的边缘变形。
