Abstract

全塑保温饭盒。本实用新型属于一种日用塑料制品,它由内胆、外壳、保温夹层、菜盒和提手组成,整个产品全部采用塑料制做,其使用寿命长,不易破损,制造简单、成本低,是一种适应城乡职工、学生使用的轻便、保险、携带方便的保温饭盒。

Description

本实用新型的塑料保温饭盒属于一种日用塑料制品。
目前生产和销售的保温饭盒由外壳和内胆组成,外壳采用塑料制做,内胆采用玻璃制做,利用玻璃制做内胆是一种较好的保温方法,保温效果好,但由于保温饭盒主要用于城乡职工、学生离工作、学习地点远而不便回家吃饭时使用,而玻璃保温内胆不能经受外界震动或碰击,当保温饭盒随同人们往返运动时,容易破损,且这种玻璃内胆制造较困难、成本高。
本实用新型的目的是提供一种不易破损,且保温性能良好的全塑保温饭盒。
附图说明:本实用新型结构图。
下面根据附图对本实用新型加以说明。
本实用新型的全塑保温饭盒由内胆(1)、外壳(2)、保温夹层(3)、菜盒(4)、盒盖(5)、提手(6)组成,其内胆(1)、外壳(2)、菜盒(4)、盒盖(5)和提手(6)均采用塑料注塑成形,整个保温饭盒为圆柱形体,在内胆(1)和外壳(2)之间及盒盖上均有一个保温夹层(3),保温夹层(3)采用绝热性能优良的聚苯乙烯发泡塑料,其导热系数为0.03,外壳,内胆等可采用抗冲击改性聚苯乙烯或共聚物聚丙烯制做,在制做外壳、内壳时应尽可能封闭,防止对流,
内壳加钛白粉、增白剂,提高防止辐射的性能,延长保温时间。
本实用新型的全塑保温饭盒与现有保温饭盒比较,具有使用寿命长,不易破损,制造简单,成本低,密封性能好,并能节约银,是一种轻便、保险、携带方便的保温饭盒。
