具体实施方式
下面将结合本申请实施例，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明的是，本申请的说明书和权利要求书及下述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以使这里描述的本申请的实施方式例如能够以除了在这里图示或描述的那些以外的顺序实施。 此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
为了便于描述，在这里可以使用空间相对术语，如“在……之上”、“在……上方”、“在……上表面”、“上面的”等，用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位置关系。应当理解的是，空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。例如，如果附图中的器件被倒置，则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而，示例性术语“在……上方”可以包括“在……上方”和“在……下方”两种方位。该器件也可以其他不同方式定位(旋转90度或处于其他方位)，并且对这里所使用的空间相对描述作出相应解释。
实施例：如图1-15所示，一种滴管盖，盖合于容器90上，滴管盖包括盖组合、上按钮20、侧按钮30、活塞50、弹性件70和滴管80，上按钮20与活塞50固定连接，活塞50活动地安装于盖组合内，侧按钮30嵌于盖组合的外壁，弹性件70安装上按钮20与盖组合之间，滴管80的第一端气密安装于盖组合内，滴管80的第二端在滴管盖与容器90的瓶口盖合时插入容器90内，且弹性件70在滴管盖和容器90的瓶口盖合时处于压缩状态，响应于侧按钮30受力向内位移，弹性件70转为舒张状态导致活塞50的运动而将容器90中的物料吸入滴管80内，且滴管盖和容器90的瓶口分离。
组装时，侧按钮30安装于盖组合，滴管80的第一端与盖组合气密组装，活塞50气密安装于盖组合内，且活塞与盖组合之间在轴向、径向等方向皆不固定，活塞在盖组合内能够相对于盖组合进行多方向滑动，或者盖组合限定了活塞轴向或径向的位置，活塞只能相对于盖组合进行径向或轴向单一方向的滑动，当滴管盖锁紧于容器90的瓶口，上按钮20处于缩回状态，弹性件70被上按钮限定而处于压缩状态，弹性件70可为弹簧或高分子弹性体，活塞50靠近于滴管的第一端；使用时，使用者挤压侧按钮30，上按钮20脱离 侧按钮30，弹性件没有了上按钮的束缚开始舒张而推动上按钮和活塞向上运动，完成滴管的吸料；进一步挤压侧按钮30，侧按钮30与容器的瓶口脱离，即滴管盖与容器解锁分离。因此，本申请通过按压侧按钮，依次完成自动吸料和脱离容器的两个动作，使用非常便利。
在滴管盖和容器90的瓶口盖合时，上按钮20与侧按钮30相互钩合而使上按钮20处于缩回状态，如图2所示，侧按钮30与容器90的瓶口相互卡合而使得滴管盖锁合于容器90；
当侧按钮30受力向内位移第一距离L1时，上按钮20脱离于侧按钮30，弹性件转为舒张状态而将上按钮20顶出，如图13所示，上按钮20带着活塞50同步运行，而完成滴管的吸料；
当侧按钮30受力向内位移第二距离L2时，侧按钮30脱离于容器90的瓶口而使滴管盖与容器解锁；
其中，第一距离L1小于或等于第二距离L2。即可将滴管盖从容器90上取下，如图14所示，当滴管80内的物料被全部挤出后，上按钮20再次与侧按钮30相互钩合，如图15所示，从而避免了上按钮20在被反复按压时大量吸入空气中的灰尘造成物料污染。
如图5、图7和图8所示，侧按钮30包括按压片31以及固定连接于按压片的侧臂32，按压片31沿其轴向方向延伸形成弹片33，弹片33上设有钩子34，容器90的瓶口设有凸沿93，上按钮20上设有第二侧孔23，在滴管盖和容器90的瓶口盖合时，钩子34卡入第二侧孔23内，侧臂32卡合于容器90的凸沿93。钩子34卡入第二侧孔23内使得上按钮20处于缩回状态，同时按压部21压住弹性件70使得弹性件处于压缩状态，当按压片31受力向内位移时，第二侧孔23脱离钩子34而使弹性件70转为舒张状态，弹性件70推动上按钮20和活塞50运行而通过滴管80从容器90中吸料，侧臂32脱离于凸沿93而使滴管盖与容器解锁。
如图5所示，盖组合包括外盖10以及固定安装于外盖中的内盖40，滴管80的第一端通过连接套60气密且固定地安装于内盖40，活塞50气密且活动地安装于内盖40。活塞50和滴管80的第一端皆设置于内盖40中，连接套60密封套设于滴管的第一端，且连接套60与内盖40气密安装，当活塞 50向上运动时能够将容器中的物料吸入滴管80，当活塞向下运动时能够将滴管80内的物料挤出。
上按钮20安装于外盖10内且上按钮20能够沿着外盖的轴向方向运行，如图7所示，上按钮20包括按压部21以及固定连接于按压部的卡合部22，卡合部22沿径向方向突出于按压部21的部分形成第二凸台24，且第二侧孔23设于卡合部22上，所按压部21顶部的内表面轴向向按压部21的内侧延伸形成连接杆25，连接杆25插入活塞50的连接筒51内而将活塞与上按钮固定连接。
如图6所示，外盖10为上下两端开口、内部中空的圆柱体结构，且外盖10的顶面设有顶孔11、侧面设有第一侧孔12，侧按钮30套设于内盖40且按压片31置于第一侧孔12内，按压部21置于顶孔11，外盖上端开口沿径向向内延伸形成一圈第一凸台14，第一凸台14用于限定上按钮20的行程，外盖10下端的内侧壁设有卡槽13且卡槽13用于固定内盖40。
其中，卡合部与按压部整体都为内部中空的圆柱体结构，且卡合部的直径大于按压部21的直径，卡合部突出于按压部的部分为第二凸台24，当弹性件处于自然状态时，第二凸台24抵靠于外盖的第一凸台14，因此第一凸台与第二凸台的设置用于限定上按钮向上的行程而有效防止上按钮被弹出外盖，当用户向下按压上按钮时，上按钮20推动活塞而完成用料操作；外盖10套设于自上而下布置的上按钮20、侧按钮30和内盖40，上按钮20和活塞50能够相对于外盖10进行上下活动，侧按钮30的按压片31置于外盖的第一侧孔12内，即侧按钮30暴露于外部而便于使用者按压，同样上按钮的按压部21置于外盖的顶孔11内而暴露于外部，当侧臂32卡合于容器的凸沿93，而将滴管盖与容器的瓶口锁定时，上按钮20被侧按钮30勾住处于缩回状态，弹性件70被上按钮约束处于压缩状态，使用时，使用者向内按压按压片31，侧臂32被挤压沿其径向外侧扩张，按压片上的钩子首先脱离上按钮，弹性件没有了上按钮的束缚开始舒张而推动上按钮和活塞向上运动，完成滴管的吸料，侧臂进一步向外扩张而脱离凸沿93，使得整个滴管盖与容器脱离。因此，本申请通过按压侧按钮的按压片，同时完成自动吸料和脱离容器的两个动作，使用非常便利。
如图9所示，内盖40包括依次固定连接的套筒45、第一安装部和第二安装部，第一安装部的上表面径向向内延伸形成第三凸台41，第一安装部与第二安装部之间设有限位槽43。第三凸台41置于容器的瓶口，且第三凸台与瓶口之间设有垫片95和内塞94，而将滴管盖于容器之间密封连接，容器的凸沿93置于限位槽43，限位槽用于限制侧按钮侧臂在变形时的空间位置，活塞50的外周壁贴合于套筒的内周壁，因此活塞只能沿着套筒的轴向方向进行滑动。
如图9所示，套筒45、第一安装部和第二安装部皆为中空的圆柱体结构，且套筒45的直径小于第一安装部的直径，第一安装部的直径小于第二安装部的直径，第二安装部突出于第一安装部而形成台阶42，第二安装部的外表面沿圆周方向形成凸筋44，弹性件70套设于套筒45且弹性件70的第一端抵靠于上按钮20，弹性件70的第二端抵靠于第三凸台41，套筒45的外表面为防滑表面用以增加与弹性件70之间的摩擦力。例如在套筒45的外表面设有若干沿其轴向方向布置的防滑筋，或在将套筒的外表面设置成网格状、花纹状、磨砂状等凸凹不平的结构，使套筒的外表面与弹性件70产生少量过盈配合，便于弹性件的固定；外盖的下部内壁沿其圆周方向设有一圈卡槽13，安装时内盖的凸筋44卡合于外盖的卡槽13内而使得外盖与内盖相互卡死，台阶42用于限制侧按钮的按压片向内按压行程。
凸沿93是设置在容器90的瓶口径向外延部分的环状结构，瓶口内安装内塞94，内盖40套设于容器90的瓶口且内盖40与内塞94之间设有垫片95。
可选地，当连接套60采用软胶材料制成时，连接套60与垫片95为一体成型件，当连接套60采用硬胶材料制成时，连接套60和垫片95为两个相互独立的部件，垫片95采用软胶材料制成；容器90包括瓶体91和肩套92，瓶体和肩套可以一体成型，也可以分别形成两个部件，再通过胶水粘接在一起形成容器，凸沿93设置于肩套92的瓶口，内塞94上设有沿其径向向外突出的凸棱96，利用凸棱与瓶口过盈配合而提高气密的效果，如图14所示，滴管80的第二端设有滴嘴81，该滴嘴与滴管呈倾斜布置。
如图8所示，侧按钮30包括两个按压片31和两个侧臂32，两个按压片的两端分别与两个侧臂固定连接，侧臂32倾斜布置且侧臂的上沿朝向侧按钮 的内侧倾斜，每个按压片31上设有一弹片33，每个弹片33上设有一钩子34。按压片与侧臂依次间隔且首尾固定连接形成环，组装时，按压片不受力，内盖40插入侧按钮的环内，且侧臂32的上沿向侧按钮围成的环内弯曲，侧臂上沿顶于容器的凸沿93(如图5所示)，而将滴管盖与容器锁定，使用时，向内挤压按压片31，首先按压片上的钩子34与上按钮的第二侧孔23脱离，进一步挤压按压片使得侧臂32沿其径向外侧扩张而脱离凸沿93，使得整个滴管盖与容器脱离，倾斜布置的侧臂32便于侧按钮的锁定与解锁。
本申请的使用过程：包括如下步骤：
步骤一：当滴管盖与容器安装完成后，处于图2的状态，此时侧按钮30的按压片31置于第一侧孔12内，且按压片31与外盖10的侧壁基本齐平，上按钮的按压部21置于顶孔11内，且按压部与外盖的顶面基本齐平，侧按钮上的钩子34钩住上按钮的第二侧孔23，即上按钮处于缩回状态，弹性件70处于压缩状态，活塞50靠近滴管80的第一端；
步骤二：使用时，用户同时按压两侧的按压片31，该按压片31的钩子脱离第二侧孔23，即上按钮20脱离侧按钮30的约束，弹性件70没有了上按钮的束缚开始舒张而推动上按钮和活塞向上运动，完成滴管的吸料，进一步按压按压片31，侧臂32被挤压沿其径向外侧扩张而脱离凸沿93，使得整个滴管盖与容器脱离，如图13所示，此时上按钮的按压部21突出于外盖10；
步骤三：再将滴管盖从容器90上取下，如图14所示，此时滴管80内吸满物料，用户使用时，通过按压上按钮的按压部21将滴管内的物料挤出，物料通过滴管的滴嘴81流出；
步骤四：当上按钮20被按压的行程达到最大距离时，滴管80中的物料被全部挤出，侧按钮上的钩子34再次钩住上按钮的第二侧孔23，上按钮处于缩回状态，如图15所示，从而避免了上按钮在被反复按压时大量吸入空气中的灰尘造成物料污染。
应当指出，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
