Description

密封盖 技术领域
本发明涉及容器，尤其涉及一种密封盖。
背景技术
容器是一种用来盛放固态或液态物体的器具。而酒杯即是用来饮酒的器具，也即是一种容器。基本器型大多是直口或敞口。这种酒杯在平常使用时，是将酒瓶内的酒倒入酒杯中，也就是说，酒是存储在酒瓶中的。然而，在人们日常生活中，一方面，可能会出现倒满的一杯酒未能全部饮用完，这时，出于卫生考虑，一般不会将酒杯中的酒倒回酒瓶，而只能倒掉，如此造成酒水的浪费。另一方面，可能会涉及外出、短途旅行等等，而在这些情况下，人们往往想携带一些能够满足自己个人饮用分量的酒水，例如几十毫升到几百毫升，甚至更多酒水，这时，如果携带一瓶酒水再加上酒杯等，则增加携带重量，携带也极为不方便。也就是说，对于类似酒杯这种容器，一般都不能进行密封，其使用不方便。

在本发明中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
参照图1、图3所示，本发明的实施例提供了一种密封盖，适于密封容器10(图1、3中的容器10为酒杯)的敞口，也就是说，容器10具有敞口，该容器10一般可以为玻璃杯，密封盖用于密封容器10的敞口。
该密封盖包括挤压盖20及柔性密封圈30。具体的，挤压盖20包括外盖201、内挡盖202、螺杆203及旋钮204，其中，外盖201盖合于敞口，内挡盖202设置于敞口内且位于外盖201的下方。也就是说，外盖201和内挡盖202是上下相对的，且两者之间具有一定的间隙。
螺杆203活动穿设于外盖201上，且螺杆203的下端与内挡盖202固定连接，螺杆203的上端与旋钮204螺纹连接。也就是说，旋钮204是用于驱动螺杆203上下运动的，当旋钮204旋转时，由于螺杆203和旋钮204是螺纹配合的，所以，螺杆203可以在外盖201上沿竖向方向上下运动。对应地，由于内挡盖202固定连接在螺杆203下端，因此，螺杆203上下运动时，可以带动内挡盖202上下运动，进而缩小或增大外盖201和内挡盖202之间的间隙。
柔性密封圈30套设在螺杆203上且位于外盖201和内挡盖202的之间，当旋钮204旋转时，螺杆203带动内挡盖202向上移动并挤压柔性密封圈 30，迫使柔性密封圈30膨胀后与敞口内周壁贴合形成密封。柔性密封可以采用硅胶等柔性材料。也就是说，柔性密封圈30是设置在外盖201和内挡盖202之间的间隙中的，当旋钮204旋转驱动螺杆203上升时，外盖201与内挡盖202之间的间隙缩小，进而对外盖201与内挡盖202之间的柔性密封圈30造成挤压，挤压的柔性密封圈30会向周围膨胀，进而贴合在敞口的内周壁上，如此，即可形成密封，容器10内的液体可以密封保存在容器10内。同时，柔性密封圈30往外膨胀顶住敞口内周壁后还起到固定住整个挤压盖20的作用。
而在需要开启时，反向旋转旋钮204，使敞口内部的内挡盖202向下运动，进而松开被挤压的柔性密封圈30，利用柔性密封圈30的弹性恢复到原来尺寸大小，方便地把挤压盖20、柔性密封圈30整体取出。
需要说明的是，外盖201及内挡盖202一般为硬质材料制成，外盖201的直径略大于敞口，以便于盖合于敞口上，而内挡盖202的直径略小于敞口的直径，以便放入和取出。
根据本发明提供的密封盖，具有挤压盖20和柔性密封圈30，当旋转挤压盖20的旋钮204时，螺杆203带动内挡盖202向上挤压柔性密封圈30，迫使柔性密封圈30膨胀而与敞口的内周壁贴合密封，如此，可对酒杯等容器的敞口进行密封。以酒杯为例，在密封后，可以将剩余的酒水通过挤压盖20和柔性密封圈30密封保存在容器10中，避免浪费，同时，还可以用于盛装适量的酒水，密封后便于携带外出，其使用方便，密封效果好。
在本发明的一个实施例中，柔性密封圈30的内周壁呈凹弧形。如图1所示，柔性密封圈30的内周壁是向外侧凹陷的，如此，在内挡盖202向上 运动进而挤压柔性密封圈30时，有利于柔性密封圈30向外侧膨胀变形，提高柔性密封圈30膨胀效果。
进一步的，在本发明的一个实施例中，外盖201的内底面设有一圈凸起2011，柔性密封圈30的上周缘套设在凸起2011的外部。也就是说，柔性密封圈30的上周缘是位于凸起2011外围的，如此，凸起2011可以对柔性密封圈30的上周缘提供定位支撑的作用，保证在内挡盖202向上运动进而挤压柔性密封圈30时，柔性密封圈30的上周缘保持圆形状态而不变形，以利于柔性密封圈30的中间部分沿径向向外膨胀，确保膨胀后的柔性密封圈30的中间部分能够与敞口的内周壁完全贴合而不产生局部间隙等问题。也就是，可以进一步提高柔性密封圈30膨胀后的密封效果。
更为有利地，在本发明的一个实施例中，螺杆203外圆周形成有两相对的导向平面2031，外盖201上设有与螺杆203相适配的非圆形孔2012，螺杆203可竖向滑动地穿设于非圆形孔2012内。如此，在旋转旋钮204时，螺杆203可沿两个导向平面2031在非圆形孔2012中上下运动，也就是说，两导向平面2031可以起到导向作用，以利于螺杆203上下滑动，提高使用的可靠性。
此外，两导向平面2031上还可以设置倒扣部2032，当螺杆203穿过外盖201上的非圆形孔2012后，倒扣部2032可以防止螺杆203从非圆形孔2012脱落，内挡盖202、柔性密封圈30掉入容器10内。
更为具体地，旋钮204的底面形成一螺纹孔2041，螺杆203的上端与螺纹孔2041螺纹配合。如此，旋转旋钮204时，由于螺杆203的上端与螺纹孔2041螺纹配合，所以螺杆203会向上运动，而对应螺杆203的上端则 会在螺纹孔2041内向上运动。这种配合方式，可以实现螺杆203上下运动，同时，结构简单，操作方便。
作为优选地，螺杆203的下端与内挡盖202一体成型，如此，可简化结构，降低成本。
参照图2所示，在本发明的一些实施例中，柔性密封圈30的上周缘形成有翻折至敞口外部的包口部，该包口部至少包括一包覆在敞口的顶壁的顶壁部301。如此，当旋转旋钮204使得螺杆203带动内挡盖202挤压柔性密封圈30膨胀密封时，旋钮204对外盖201也产生向下的作用力，进而使得外盖201的内底面将顶壁部301压紧在敞口的顶壁上，如此，可以使敞口形成第二道密封，以提高密封效果。
更为有利地，在本发明的一个实施例中，包口部还包括一包覆在敞口的外周壁的外围部302，外围部302通过一卡箍40夹紧贴合在敞口的外周壁形成密封。
如此，通过卡箍40可以使得外围部302与敞口形成第三道密封，如此，可以进一步提高其密封效果。
在本发明的一个实施例中，卡箍40包括套设在外围部302的卡圈401及调节卡圈401大小的锁紧螺栓402。在使用过程中，先调整卡圈401变大，套设在外围部302上，再通过调节锁紧螺栓402使得卡圈401逐渐缩紧，进而将外围部302箍紧贴合在敞口的外周壁上形成密封，其使用方便，卡圈401的卡箍40力度可以通过锁紧螺栓402调节，密封更好。
综上所述，本发明提供的密封盖，具有挤压盖20和柔性密封圈30，当旋转挤压盖20的旋钮204时，螺杆203带动内挡盖202向上挤压柔性密封 圈30，迫使柔性密封圈30膨胀而与敞口的内周壁贴合密封，如此，可对酒杯等容器10的敞口进行密封。以酒杯为例，在密封后，可以将剩余的酒水通过挤压盖20和柔性密封圈30密封保存在容器10中，避免浪费，同时，还可以用于盛装适量的酒水，密封后便于携带外出，其使用方便，密封效果好。
