Description

一种易拉开瓶盖 技术领域
本实用新型涉及密封技术领域， 特别涉及一种易拉开瓶盖。
背景技术
目前， 绝大多数用来封盖装有啤酒、 饮料等的瓶盖都为皇冠盖， 由于其成型容易， 原材 料国内可供应， 且价格低廉， 适合于国内大多数消费者使用。 使用时， 一般需要配套专用的 启瓶器， 当没有启瓶器时， 大多数消费者只能采用用钥匙撬或是借助桌边磕， 不但有失文 明， 还有可能发生使钥匙弯曲变形， 磕坏桌子的事故， 给消费者带来不便与烦恼。
为了解决上述问题， 人们生产了一种带易拉环的瓶盖。 现有技术中， 常见的是采用了在 瓶盖上铆接拉环， 且拉环的形状都采用圆环的形式， 人们在使用时， 圆环太过于光滑， 人们 并不能很方便的捏住圆环， 经常会脱落， 给人们造成一些不必要的麻烦。
因此， 现有技术还存在有缺陷， 有待于改进和发展。
实用新型内容
有鉴于此， 有必要针对上述出现的问题， 提供一种能大规模生产， 便于人们使用， 且美 观的易拉开瓶盖。
为此本实用新型提供如下技术方案：
一种易拉开瓶盖， 包括瓶盖主体、 拉环和连接片， 连接片的一端连接于拉环， 另一端连接于 瓶盖主体的侧边缘， 所述拉环的外边缘为多边形， 内边缘为圆形、 椭圆形或多边形； 所述瓶 盖主体的端面设置有凹陷区以容纳拉环。
进一步的， 所述凹陷区底面为平面。
进一步的， 所述凹陷区底面为弧形面。
进一步的， 相对于所述瓶盖的端面， 所述弧形面向瓶身方向凹陷。
进一步的， 所述瓶盖主体的侧边缘上设置有开启线。
进一步的， 所述开启线设置有两条， 分别位于拉环与瓶盖主体侧边缘连接处的两侧。 进一步的， 还包括密封层， 所述密封层紧贴于瓶盖主体端面的内表面。
进一步的， 所述瓶盖主体、 拉环和连接片为一整体成型， 且凹陷区为一体冲压形成。 进一步的， 所述多边形为八边形。
本实用新型所述的拉环外边缘采用多边形， 内边缘采用圆形或椭圆形， 采用这种设计有 利于人们在使用时更方便的捏住拉环， 不容易脱落。

具体实》式
为使本实用新型实施例的目的、 技术方案和优点更加清楚， 下面将结合本实用新型实施 例和附图， 对本实用新型实施例中的技术方案进行清楚、 完整地描述。 需要说明的是， 所描 述的实施例仅仅是本实用新型一部分实施例， 而不是全部的实施例。 基于本实用新型中的实 施例， 本领域普通技术人员在没有付出创造性劳动前提下所获得的所有其他实施例， 都属于 本实用新型保护的范围。
下面结合附图说明本实用新型的具体实施方式。
实施例一
如图 1所示， 本实施例所提供的易拉开瓶盖， 包括瓶盖主体 1和拉环 2和连接片 11， 连接 片 11的一端连接于拉环 2， 另一端连接于瓶盖主体 1的侧边缘， 连接片 11将拉环 2与所述 瓶盖主体 1连为一体； 所述拉环 2的外边缘 4为八边形 （在本是实施例中优选八边形， 当然 其他多边形行也适用于此）， 外边缘的边与边的交界处有倒圆角处理， 内边缘 5 为圆形 （当 然， 也可以是椭圆形， 使得内边缘光滑过度， 不对手指造成创伤为准）； 所述瓶盖主体 1 的 端面中心处设置有凹陷区 6， 凹陷区底面 10为平面。 需要说明的是， 所述瓶盖主体 1、 拉环 2、 连接片 11和凹陷区 6在本实施例中优选采用一体冲压成型， 即瓶盖主体 1、 拉环 2、 连 接片 11和凹陷区 6是同一个整体， 并没有采用外加材料进行拼接组装。
如上所述， 所述拉环 2的外边缘 4为八边形， 内边缘 5为圆形， 摒弃了以往大众最常采 用 "外边缘 4和内边缘 5同时采用圆形" 的设计， 采用此设计的优势在于， 人们在使用时更 方便的捏住拉环 2， 不容易脱落， 相对于拉环 2内外边缘同时采用圆形的设计， 本实施例更 适合实际应用。 众所周知， 有时受外在条件的影响， 比如天气潮湿， 手指上有油污等类似情 况下， 用手指直接去接触圆滑形物体， 很容易从手指上脱落， 但接触有棱角的物体， 人们很 容易拿捏稳固， 所以本实施例涉及到的拉环 2外边缘 4采用八边形设计， 利于人们捏住拉环 2， 且本实施例拉环 2的内边缘 5采用圆形设计， 避免对手指造成创伤， 也使得人们的触摸 感觉更良好。
如上所述， 连接片 11位于瓶盖主体 1的侧边缘 3， 与所述瓶盖主体 1连为一体， 拉环 2 和连接片 11可以向瓶盖主体 1 的端面翻叠， 最终嵌入在瓶盖主体 1端面的凹陷区 6, 需要 说明的是， 此处优选凹陷区 6的凹陷深度与拉环 2的厚度相吻合，， 凹陷区 6的形状和拉环 2的外边缘相吻合， 当拉环 2嵌入在凹陷区 6时， 与凹陷区 6完全吻合。 此时， 拉环 2与凹 陷区 6组合形成的组合体的水平面， 与瓶盖主体 1端面未凹陷区域的水平面相水平， 不会形 成凸起结构， 且本实施例中的凹陷区 6 为统一向瓶身方向凹陷 （也可以理解为向下凹陷）， 并非是为配合拉环 2嵌合而设计的环状凹陷区域， 采用此设计的优势在于， 人们在使用时更 方便的捏起拉环 2， 且能有效的利用现有的模具进行大规模的工业化生产， 而不需重新去设 计和制造新模具， 节约了生产成本。
所述瓶盖主体 1的侧边 9上设置有开启线 7， 所述开启线 7优选两条， 两条开启线 7的 具体位置优先设置于， 以连接片 11 为对称轴， 对称分布在瓶盖主体 1 的侧边 9， 以便有力 作用在拉环 2上时， 两条开启线 7能均匀受力。 当人们使用时， 只需轻拉拉环 2就可以拉开 开启线 7， 从而把瓶盖拉出缺口， 最终达到开启整个瓶盖的目的， 即破盖开瓶。
如图 2所示， 本实施例提供的易拉开瓶盖还包括密封层 8， 所述密封层 8紧贴于瓶盖主 体 1端面的内表面。
实施例二
如图 3 所示， 实施例二所提供的易拉开瓶盖， 与实施例一不同之处在于： 所述凹陷区底面 10 是弧形面， 且弧形面向瓶盖主体 1 的内部凹陷。 采用此设计的优势在于， 当人们准备使 用拉环 2开启瓶盖时， 人首先需要用手指把拉环 2给勾起， 采用向瓶盖主体 1内部凹陷的弧 形面设计， 更能方便人们勾起拉环 2， 进而开启瓶盖。
实施例二的其他设计与实施例相同， 在此不再重复叙述。
在现有技术揭露的易拉开瓶盖中， 开始状态时， 易拉环蛰伏在瓶盖主体的端面上， 在使 用时， 用手拉开易拉环， 从而拉开瓶盖， 此种设计的好处是解决了没有启瓶工具时， 人们同 样能开启瓶盖， 但不足之处在于： 易拉环蛰伏在瓶盖主体的端面上， 形成凸起， 铆接处同样 会出现凸起， 在流水线上生产时， 会时常出现卡机情况， 不利于大规模的工业化生产； 本实用新型采用一体冲压成型的方法， 是瓶盖、 拉环、 连接片和凹陷区都是一个整体， 并没 有采用外接的方式增加部件， 且拉环和凹陷区在叠合时， 与瓶盖主体的端面位于统一水平 面， 并未在瓶盖端面上形成凸起部位， 采用这种方式有利于工业化的大规模生产； 本实用新 型的凹陷区为统一向下凹陷， 并非是为配合拉环叠合而设计的环状凹陷区域， 采用这种涉有 利于人们在使用时更方便的捏起拉环；
以上所述实施例仅表达了本实用新型的几种实施方式， 其描述较为具体和详细， 但并不能因 此而理解为对本实用新型专利范围的限制。 应当指出的是， 对于本领域的普通技术人员来 说， 在不脱离本实用新型构思的前提下， 还可以做出若干变形和改进， 这些都属于本实用新 型的保护范围。 因此， 本实用新型专利的保护范围应以所附权利要求为准。
