Abstract

封闭件(1)具有盖帽(2)，其通过铰链(3)可枢转地成型到封闭件(1)上。在封闭件(1)和盖帽(2)的侧面上成型有倒钩，在关闭盖帽(2)时，倒钩在盖帽(2)横向于闭合方向凸起的情况下向外偏移。因此，倒钩在封闭件(1)上在其外边缘上滑动，并且然后通过凸起回弹而接合。然后将盖帽(2)以密封且牢固的方式固定到封闭件(1)上。盖帽(2)利用其前部区域以其边缘(11)搁置在封闭件(1)的台阶(9)上。通过沿铰链(3)的方向按压在前部区域上，此边缘(11)可在台阶(9)的平面上滑动。这产生盖帽(2)的侧向边缘的双侧凸起，使得盖帽(2)上的倒钩(26)与封闭件(1)上的那些倒钩脱离。此后，在压力释放后的凸起回弹下，盖帽(2)然后可通过在其前部区域上的持续压力围绕铰链(3)枢转打开。

Description

具有盖帽的封闭件
技术领域
本发明涉及具有盖帽的封闭件。
背景技术
这种封闭件是被拧到罐(诸如油罐、用于液体洗涤剂和许多其他液体或自由流动物品的罐或塑料瓶)的颈部上的。然后，拧到颈部上的封闭件成型壶嘴，并且在枢转打开相关的盖帽之后，可以受控的方式倒出或分配液体或自由流动产品的均匀射流。在塑料封闭件的情况下，这种封闭件上的盖帽通过铰链保持在封闭件上。铰链可被设计成将枢转打开的盖帽保持在打开位置。当盖帽向下枢转时，必须超过铰链的最大拉力进行枢转，然后盖帽向下枢转并通过盖瓣上方压力克服枢转到关闭位置的最后几度的角。盖帽的内侧上有倒钩、肋或凹槽，它们与封闭件上的倒钩、肋或凹槽相互作用，使得盖帽在其闭合位置接合在封闭件上并保持其上。
盖帽的作用是在不使用罐或容器时防止任何东西通过封闭件掉入容器中，另一方面，防止任何内容物意外溢出，即，封闭件是紧密封闭的。这种封闭件的数以百万计的实例存在于相应罐和容器上。
然而，这些常规的封闭件及其相应盖帽具有以下缺点：如果容器或瓶子掉落，则盖帽经常跳开，因为它们在撞击地面时所承受的冲击力导致与封闭件的紧密抓合松开。倒钩、肋或凹槽被设计成使其在盖上盖帽时容易弯曲并且因此可相互穿过，然后钩到彼此上。为了释放，通过增加使盖帽枢转打开的拉力克服抓合。许多这样的盖帽以相对较弱的抓合保持在封闭件上，或者在另一个极端情况下，盖帽对封闭件抓合太强，使得至少对于双手力量有限的人而言，很难枢转打开盖帽。许多已知盖帽的其它缺点还在于，它们容易被幼儿枢转打开，优选地，应防止这将情况，以避免幼儿能够从这种瓶中饮用其内含物或使内含物溢出。
发明内容
因此，本发明的目的是提供一种具有盖帽的封闭件，当将盖帽枢转闭合到所述封闭件上时，该盖帽易于与封闭件接合，并且然后在闭合位置时盖帽被牢固地保持在封闭件上，使得即使在当装有封闭件的容器跌落或掉落到地板上时，盖帽不会突然打开，并且也不能仅通过以足够的力枢转的运动就用一只手将盖帽打开。
此目的通过具有盖帽的封闭件来实现，该盖帽通过铰链可枢转地成型到封闭件上并且在枢转闭合时在至少两个点处可解除地与封闭件抓合或接合，封闭件的特征在于，盖帽可通过在仅一个点上的压力而变形，从而可通过这种变形而解除抓合，并且在持续施加压力的情况下可用一只手将盖帽在抓合装置的旁侧枢转打开。
附图说明
在附图中，描绘这种具有盖帽的封闭件的示例性实施例，并且在下文中对其进行描述，并且将解释其功能。

具体实施方式
在帽和盖帽之间，接合或抓合装置作用，使得当将盖帽关闭到封闭件上时，这两个或更多部分彼此接合或抓合。接合或抓合装置可例如通过相互钩合的倒钩实现。当关闭盖帽时，由于盖帽的壁向外侧弹性地弯曲，在盖内壁上一体式地成型的倒钩滑过存在封闭件外侧上的倒钩或进入存在封闭件外侧上的凹槽中，并且因此倒钩在凹槽中接合或相互抓合进而成型牢固的抓合连接。代替倒钩，可一体式地成型有相互配合的成形元件。常规的具有盖帽的封闭件允许只将盖帽轻微地卡扣到封闭件上以将其保持在闭合位置，使得在很小的力的情况下，便能够克服这种固定并且能够枢转打开盖帽。如果需要更牢固的抓合连接，则会出现如何能再次解除抓合连接以打开盖帽的问题。
图1以透视图以从上方一定角度示出根据本发明的封闭件的示例性实施例，其中，盖帽闭合。封闭件1在下面，并且盖帽2在上面，枢转打开。铰链3以已知方式位于后侧。作为一个特别的特征，盖帽2在其前侧上形成有突出的按钮4，可将该按钮4沿铰链3的方向相对于按钮4的相应前侧壁弹性地按压一定程度。
图2示出从下方以一定角度查看的盖帽2闭合的封闭件。在此视图中，可以看到成型在封闭件1的内侧上的套筒5以及其内螺纹6。因此，封闭件可被拧到容器或瓶子的螺纹颈部上。在顶部，套筒5由圆盘8闭合，除了用作倾倒或分配孔7的中心孔。可在封闭件1的后端及其盖帽2看到铰链3，所述铰链根据本领域中已知方式将两个部分1、2和相应两个夹紧带25连接为一体。
图3示出盖帽2稍微枢转打开的封闭件1，其中，倒钩的抓合是解除的。在封闭件1的两侧的每一侧上都形成有台阶9，盖帽2能够以其周向侧壁10精确地缩回到所述台阶上，因此使得侧壁10的下边缘11牢固地搁置在此台阶9上。在台阶9上方成型有凹槽12，所述凹槽在顶部具有锐角13。侧壁10的内侧上的倒钩(在此不可见)可接合到倾倒封闭件1的两侧的这些凹槽12中，因为当具有倾斜表面的倒钩在封闭件1的上外边缘14上滑动时，侧壁10可向外侧偏移或弹性弯曲。在封闭件1的前部有凹槽16，其从另一外侧15向后缩进。这在盖帽2的前部形成解锁和按压点17(这里呈椭圆形按钮4的形式)，其下半部分作为自由圆盘适配在凹槽16中，而按钮4的上半部分用盖帽2的侧壁10加固并连接到该侧壁。如在图3中可见，台阶9在封闭件1的前部区域18中加宽。如果盖帽2的侧壁10的下边缘11现在牢固地搁置在台阶9上并且与封闭件1的外壁齐平，通过在按钮4上施压，盖帽的侧壁可在此加宽的台阶9上向内滑动。结果，盖帽2的两个侧壁10在侧面凸起并且一体式成型在其内侧上的倒钩从封闭件1上的凹槽12中移出，并且因此解除抓合。在这种状态下，盖帽2可绕铰链3枢转。
图4给出从下面以一定角度查看的盖帽2稍微枢转打开的封闭件1的示图，其中，倒钩的抓合是解除的。可看到一体式地成型在盖帽2的底部上的颈部19。所述颈部的直径比封闭件1的底部处的套筒5的直径略小，并且如此处所示，可设有呈橡胶O形圈形式的环形橡胶密封件20。加强肋21在盖帽2的内部支撑颈部19的稳定性。
基于示出暴露的封闭件的上侧的视图并且使得能够查看盖帽2内部的图5，此颈部19的重要性和作用显而易见。封闭件1形成有平坦表面23，并且在其中成型凹槽24，凹槽24的周壁22突出到一体式地成型在下方的套筒5中。如图2所示，凹槽24具有由圆盘8形成的底部。在此圆盘8的中央，存在倾倒孔7。当盖帽2围绕铰链3枢转到封闭件1上时，颈部19穿入封闭件1上的凹槽24中，颈部19的密封件20然后密封地邻接周向壁22。这在盖帽2闭合并与封闭件接合时实现封闭件1的非常好的密封。
图6示出从下方以一定角度查看的盖帽2枢转打开180°的封闭件1，并且图7以俯视图从上方示出封闭件1。具有密封件20的颈部19适配到凹槽24的内部。代替为颈部19配备外部邻接的密封件20，凹槽24的周向壁22也可带有密封件。在此图示中，可在铰链3的两侧的每侧看到夹紧带25。通过整个封闭件1及其盖帽2的轻微变形，这些夹紧带25确保盖帽2能够以超过最大拉力的方式闭合并且再次枢转打开。这确保盖帽2保持在其打开位置。
图8以中心纵向截面示出盖帽2稍微枢转打开的封闭件1。在此图示中，可在盖帽2的侧壁10的内侧看到倒钩26中的一个。这些是具有楔形横截面的元件，其宽度和厚度朝着顶部连续增加并在顶部相对于内部成型锐角的边缘27。
在图9(其示意性地示出封闭件)中清晰可见从其闭合状态开始的此封闭件的操作。最好用拇指按压解锁和按压点17(在此处设计为按钮形式)的正面，如粗体箭头所示。如图10所示，解锁和按压点17也可被成型为，使得当由定心装置29制动时可靠地防止倾斜。定心装置可由位于按钮后面的肋30组成，在按压该肋时，其被压入封闭件上具有V形横截面的定心凹槽31中，并且因而使解锁和按压点17居中，使得盖帽2的侧壁10对称地向外凸起，如图11中的两个小箭头所示，并且两个倒钩26均匀地从其内侧的凹槽12中被推出。通过继续按压按钮4或解锁和按压点17，现在盖帽2可同时向上枢转。然而，仅通过在盖帽顶部上施加足够大的压力枢转闭合盖帽2来使其关闭。因此，倒钩以其倾斜表面28在环周台阶的外边缘上滑动并越过封闭件1接合到下面的凹槽12中，其中，每个倒钩26的锐角边缘27与封闭件上的相应凹槽12的锐角13接合。
虽然还是通过双重动作打开封闭件，这仍可用单手进行，即，首先按压单个解锁和按压点17，即按压单个按钮4，并且同时使盖帽2枢转打开。这既可用两只手完成，也可完全用一只手完成。这对于幼儿来说是困难的。此外，即使当容器翻倒或例如从桌子掉落到地板时，此盖帽2仍牢固地固定在封闭件1上。结果，即使在这些情况下，封闭仍保持紧密。
