Abstract

本实用新型涉及一种易拉盖,尤其是一种防爆型易拉盖,包括盖本体(1)、开启舌片(2)、拉环(3),盖本体(1)上设有手指槽(4)和线号(6),开启舌片(2)是通过在盖本体(1)上加工刻痕线(5)而形成,拉环(3)与盖本体(1)通过位于盖本体平面中心的铆钉(7)相连接,通过在开启舌片(2)靠近铆钉(7)的区域上设置一条防爆刻线(8),使局部产生一个应力用以抵消罐装产品在开启时的由于内压而产生的开启力,防止整个开启舌片(2)瞬间全部打开而伤害消费者。

Description

一种防爆型易拉盖
技术领域
本实用新型涉及一种易拉盖,尤其是一种防爆型易拉盖。
背景技术
目前普通的易拉盖常采用图1所示的形状和构造,包括盖本体1、开启舌片2、拉环3,盖本体上设有手指槽4和线号6, 开启舌片2是通过在盖本体1上加工刻痕线5而形成,拉环3与盖本体1通过位于盖本体平面中心的铆钉7相连接,这种易拉盖在刻痕线5处的应力过于集中,灌装后,在罐内压的作用下开启,开启舌片3会瞬间爆开伤害消费者。
实用新型内容
为克服上述缺点,本实用新型通过在开启舌片表面靠近铆钉区域处设置一条防爆刻线,从而消除刻痕线处的应力集中,增强该部位的强度,避免开启瞬间舌片爆开。
本实用新型是这样实现的:一种防爆型易拉盖,包括盖本体、开启舌片、拉环,盖本体上设有手指槽, 开启舌片是通过在盖本体上加工刻痕线而形成,拉环与盖本体通过位于盖本体平面中心的铆钉相连接,在开启舌片表面靠近铆钉区域处通过防爆刻线刀对盖面的直接挤压,使材料产生塑性变形,从而形成一条防爆刻线,防爆刻线的深度范围为0.04—0.08mm,该防爆刻线的两个端点到到盖本体纵向中轴线的距离分别为2.91mm和1.44mm,到盖本体面横向中轴线的距离分别为3.78mm和5.02mm。
该防爆刻线有效地消除了刻痕线处的应力集中,增强该部位的强度,避免开启瞬间舌片爆开。
附图说明
图1为目前普遍采用的易拉盖的平面图。
图2为本实用新型所设计的易拉盖的平面图。
图3为盖体的平面图。
具体实施方式
如图2和图3所示,本实用新型所涉及的易拉盖,包括盖本体1、开启舌片2、拉环3,盖本体上设有手指槽4, 开启舌片2是通过在盖本体1上加工刻痕线5而形成,拉环3与盖本体1通过位于盖本体平面中心的铆钉7相连接,在开启舌片2表面靠近铆钉7区域处通过防爆刻线刀对盖面的直接挤压,使材料产生塑性变形,形成一条防爆刻线8,该防爆刻线8的两个端点A、B到盖本体纵向中轴线9的距离分别为2.91mm和1.44mm,到盖本体面横向中轴线10的距离分别为3.78mm和5.02mm,防爆刻线8的深度范围为0.04—0.08mm。
