Description

卡式断瓣盖及具有该瓶盖的容器
技术领域
本发明涉及一种瓶盖， 特别是涉及一种打开后产生明显结构变化的防伪 瓶盖。
背景技术
在酒类等贵重液体包装领域， 为了使消费者能够区分容器是否开启过， 采用各种防伪手段对瓶盖进行设计， 其中通过在上下盖套之间设计瓣片或齿 使其在开启时断裂脱落来指示容器已被打开的防伪方式应用广泛。
上述防伪装置的具体结构如申请人之前的中国专利 201020229088. 1， 该 防伪结构在应用范围上有很大的局限性， 即上下盖套材料必须使用脆性材料， 才能在旋转力的作用下将瓣 /齿切断脱落，对于韧性较好的材料（如 PP材料）， 瓣 /齿在旋转切力作用下容易向外翻出， 使得上盖从瓣 /齿的内部转过， 瓣 /齿 并未被上盖凹槽壁切断， 这样开启后， 造假者可轻易恢复， 导致防伪失效。 发明内容
本发明要解决的技术问题是提供一种新型卡式断瓣结构的瓶盖， 该结构 可应用材料范围更广， 保证防伪效果的稳定。 本发明卡式断瓣盖， 包括上盖和下套筒， 所述下套筒通过固定装置固定 在容器上， 所述上盖和下套筒的侧壁上分别设有凸片和凹槽， 所述凹槽位于 上盖或下套筒的边缘， 所述凸片位于下套筒或上盖的边缘， 且位于凹槽中， 所述上盖的下边缘与下套筒的上边缘相邻且相分开， 所述凸片的内壁上设有 多条凸筋， 所述凸片通过凸筋连接在下套筒或上盖的边缘。
本发明卡式断瓣盖， 其中所述凸片通过凸筋连接在下套筒的上边缘上， 所述凹槽包括第一凹槽和第二凹槽， 所述第一凹槽位于上盖的外壁， 第二凹 槽位于上盖的内壁， 所述第一、 第二凹槽相连通， 第一凹槽沿上盖外壁周向 延展的宽度大于第二凹槽沿上盖内壁周向延展的宽度， 所述凸片位于第一凹 槽中， 所述凸筋位于第二凹槽中。
本发明卡式断瓣盖， 其中所述凸片通过凸筋连接在上盖的下边缘上， 所 述凹槽包括第一凹槽和第二凹槽， 所述第一凹槽位于下套筒的外壁， 第二凹 槽位于下套筒的内壁， 所述第一、 第二凹槽相连通， 第一凹槽沿下套筒外壁 周向延展的宽度大于第二凹槽沿下套筒内壁周向延展的宽度， 所述凸片位于 第一凹槽中， 所述凸筋位于第二凹槽中。
本发明卡式断瓣盖， 其中所述凸筋设置为两条。
本发明卡式断瓣盖， 其中所述凸片和凹槽分别设置两个。
本发明卡式断瓣盖， 其中还包括倾倒出口装置， 所述倾倒出口装置的上 部通过螺紋配合在上盖内， 倾倒出口装置的下部外壁设有径向向外延伸的连 接部， 所述连接部的上表面上设有第一齿部， 所述下套筒上部内壁上设有径 向向内突出部， 所述突出部的下表面上设有第二齿部， 所述连接部置于突出 部的下部且与其相干涉， 所述第一齿部与第二齿部相啮合干涉。
本发明卡式断瓣盖， 其中所述倾倒出口装置的下方还设有单向阀， 所述 单向阀包括阀座和置于阀座内的阀芯， 所述阀座的上部紧配合在倾倒出口装 置的内壁上， 阀座的下部紧配合在容器口部。
本发明卡式断瓣盖， 其中所述下套筒的内壁上设有若干纵向凸棱和向上 倾斜的凸起构成将下套筒固定到容器上的固定装置。
一种使用上述卡式断瓣盖的容器， 所述容器的口部适于容纳所述阀座， 容器口部外侧具有一条环形凸起和若干纵向凸起， 所述向上倾斜的凸起位于 环形凸起下方且与其相干涉， 所述纵向凸棱分布在纵向凸起之间且相互干涉。
本发明卡式断瓣盖与现有技术不同之处在于本发明卡式断瓣盖设置上盖 的下边缘与下套筒的上边缘不通过脆性部分连接而是独立相邻的两个件， 凸 片也不再是直接连接在下套筒或上盖边缘上， 而是在凸片内壁上设置多条凸 筋， 通过凸筋连接在下套筒或上盖的边缘上， 使得凸片主体处与下套筒或上 盖边缘并无直接连接关系， 凸片主体面与下套筒或上盖的壁位于同一面上， 而凸筋则位于下套筒或上盖的壁内部， 这样， 当旋转上盖剪切凸片上的凸筋 时， 凸筋便无法向外挤出避开凹槽壁的剪切力， 而必然被剪断使得凸片脱落 露出上盖或下套筒上的凹槽， 警示容器已被开启， 这样的结构， 使得韧性较 强的材料也可被稳定的剪断脱离， 保证了防伪效果的稳定。
本发明卡式断瓣盖中， 进一步设置凹槽由第一凹槽和第二凹槽连通组成， 第一凹槽位于上盖或下套筒的外壁， 第二凹槽位于上盖或下套筒的内壁， 并 使第一凹槽沿上盖或下套筒外壁周向延展的宽度大于第二凹槽沿上盖或下套 筒内壁周向延展的宽度， 使得凸片位于第一凹槽中， 凸筋位于第二凹槽中， 这样进一步增加了凹槽对凸筋的剪切力， 并且由于第二凹槽沿上盖或下套筒 外壁周向延展的宽度小于第一凹槽沿上盖或下套筒内壁周向延展的宽度， 当 凸片脱落后， 第二凹槽可对内部结构起到遮蔽的作用， 外观上更加美观。
下面结合附图对本发明的卡式断瓣盖作进一步说明。 附图说明

图 2为本发明卡式断瓣盖中下套筒的立体图；
图 3为本发明卡式断瓣盖中上盖的立体图；
图 4为本发明卡式断瓣盖从上盖凹槽部分截断除去上盖部分的立体图。 具体实施方式
如图 1所示， 本发明卡式断瓣盖包括上盖 1和下套筒 2， 上盖 1的下边缘 与下套筒 2的上边缘相邻且相分开。 如图 4所示， 下套筒 2的内壁上设有若 干纵向凸棱 10和向上倾斜的凸起 11， 容器口部外侧具有一条环形凸起 12和 若干纵向凸起 13， 下套筒 2的向上倾斜凸起 11位于环形凸起 12下方且与其 相干涉， 纵向凸棱 10分布在纵向凸起 13之间且相互干涉， 将下套筒 2固定 到容器上。
如图 2所示， 下套筒 2的上边缘上设有两个凸片 3， 凸片 3的内壁上设有 两条凸筋 31， 凸片 3通过凸筋 31连接在下套筒 2的上边缘上， 如图 3所示， 上盖 1的侧壁下边缘上设有两个凹槽 4， 凹槽 4包括第一凹槽 41和第二凹槽 42， 第一凹槽 41位于上盖 1的外壁， 第二凹槽 42位于上盖 1的内壁， 第一 凹槽 41、 第二凹槽 42相连通， 第一凹槽 41沿上盖 1外壁周向延展的宽度大 于第二凹槽 42沿上盖 1内壁周向延展的宽度， 如图 4所示， 凸片 3位于第一 凹槽 41中， 凸筋 31位于第二凹槽 42中。
如图 1所示， 本发明卡式断瓣盖还包括倾倒出口装置 5， 倾倒出口装置 5 的上部通过螺紋配合在上盖 1内， 下部外壁设有径向向外延伸的连接部 6， 连 接部 6的上表面上设有第一齿部， 如图 2、 4所示， 下套筒 2上部内壁上设有 径向向内突出部 7， 突出部 7的下表面上设有第二齿部， 连接部 6置于突出部 7的下部且与其相干涉， 第一齿部与第二齿部相啮合干涉， 使得倾倒出口装置 5与下套筒 2保持固定。倾倒出口装置 5的下方还设有单向阀， 单向阀包括阀 座 8和置于阀座 8内的球状阀芯 9，阀座 8的上部紧配合在倾倒出口装置 5的 内壁上， 阀座 8的下部紧配合在容器口部。
本发明卡式断瓣盖的组装过程是这样的： 先将上盖 1上的两个凹槽 4与 下套筒 2上的两个凸片 3对应将上盖 1和下套筒 2组装到一起， 然后将倾倒 出口装置 5旋装或压装到上盖 1中并使得连接部 6抵靠到突出部 7下面， 第 一齿部与第二齿部交叉啮合， 再将单向阀压装到倾倒出口装置 5 内， 最后将 整个瓶盖压装到容器上， 使得下套筒 2的向上倾斜凸起 1 1卡在容器口部外侧 的环形凸起 12下， 纵向凸棱 10与容器口外侧的纵向凸起 13交错配合。
作为本发明的简单变型， 也可将凸片连接在上盖的下边缘上， 凹槽设置 在下套筒的上边缘上； 凸片和凹槽的数量可设置多个。
以上所述的实施例仅仅是对本发明的优选实施方式进行描述， 并非对本 发明的范围进行限定， 在不脱离本发明设计精神的前提下， 本领域普通技术 人员对本发明的技术方案作出的各种变形和改进， 均应落入本发明权利要求 书确定的保护范围内。
