Abstract

本实用新型公开了一种伸缩饭盒,上套环、中套环和下底环同轴,上套环、中套环和下底环的顶面直径均大于底面直径,中套环的顶面直径小于上套环的顶面直径而略大于上套环的底面直径,下底环的顶面直径小于中套环的顶面直径而略大于中套环的底面直径,下底环的底面闭合,饭盒盖与上套环通过锁扣连接。本实用新型提供的可伸缩饭盒,平时不用可以收缩起来,大大减少饭盒的体积,非常方便携带,而且盒盖上设有锁扣,不用担心汤水溢出。

Description

伸缩饭盒
技术领域
本实用新型涉及一种饭盒,特别是一种可伸缩饭盒。
背景技术
目前在使用的饭盒体积较大,比较占位置,不太方便。
发明内容
本实用新型的目的是要提供一种可伸缩饭盒,平时不用可以收缩起来,大大减少饭盒的体积。
本实用新型的目的是这样实现的:一种伸缩饭盒,上套环、中套环和下底环同轴,上套环、中套环和下底环的顶面直径均大于底面直径,中套环的顶面直径小于上套环的顶面直径而略大于上套环的底面直径,下底环的顶面直径小于中套环的顶面直径而略大于中套环的底面直径,下底环的底面闭合,饭盒盖与上套环通过锁扣连接。
本实用新型提供的可伸缩饭盒,平时不用可以收缩起来,大大减少饭盒的体积,非常方便携带,而且盒盖上设有锁扣,不用担心汤水溢出。
附图说明
下面结合附图和实施例对本实用新型作进一步说明。
图1是本实用新型整体结构示意图。
具体实施方式
一种伸缩饭盒,上套环1、中套环2和下底环3同轴,上套环1、中套环2和下底环3的顶面直径均大于底面直径,中套环2的顶面直径小于上套环1的顶面直径而略大于上套环1的底面直径,下底环3的顶面直径小于中套环2的顶面直径而略大于中套环2的底面直径,下底环3的底面闭合,饭盒盖4与上套环1通过锁扣5连接。
使用时下拉下底环3,下底环3顶面边缘与中套环2的底面内缘楔紧,中套环2的顶面边缘与上套环1的底面内缘楔紧,从而可以使用饭盒。不用时,压下上套环1和中套环2,各楔紧部位松开,体积缩小,此时便于收藏。
