Description

一种瓶盖及具有该瓶盖的油瓶 技术领域
本发明涉及厨房用品领域，具体涉及一种瓶盖，以及具有该瓶盖的油瓶。
背景技术
目前市场销售的食用油，采用各种油瓶或油桶盛装，这些包装容器，主要考虑储藏和运输，一次性使用，即便是小包装的油瓶，其倒油设计也简化，滴漏油现象严重，不太适合厨房场合长期使用。所以人们喜欢用一些可长期使用的油瓶，(或称油壶，)将大桶的油分装，在厨房场合使用。下文便是叙述此类油瓶，此类油瓶也可盛装酱油、料酒等液体。一个油瓶的好坏，主要从储油、倒油、清洁卫生方面来衡量。
关于储油，众所周知，食用变质的食用油会导致老年痴呆、老年斑、脂肪肝、癌症、中毒等一系列健康问题。食用油的原包装一旦启封，用油瓶分装，食用油的酸败现象就开始加速，我们要尽量延缓这个变质过程。其变质条件离不开水分、氧气、光线、温度。对付水分、氧气，一般要求油瓶密封性好，不透气就可以。对付光线、温度，要求油瓶远离厨房火源、阳光、照明光线，可以把油瓶放置在遮光的橱柜里。在炎热的地区或季节，可以把油瓶在冰箱冷藏室，这样会大大减缓食用油酸败现象。所以要求油瓶在保证一定储油量情况下，占用空间尽量小，便于油瓶收纳。
关于倒油，目前人们使用的主流油瓶，采用手握油瓶，调整倾斜角度，控制倒油流量、时间，完成倒油。下文分析这种工作原理的几款油瓶优缺点，和一款挤压式油瓶优缺点。
关于清洁卫生，要求油瓶倒油结束时，油嘴滴漏油越少越好；要求瓶盖和瓶口连接处不漏油，油瓶外部保持干净；要求油瓶设计合理，方便拆卸，方便使用者定期清洗油垢。
目前市场上有两种油瓶，瓶盖一侧设有提手，瓶盖上设有油嘴和透气孔，此瓶盖上方铰接一个设有配重块的盖子，或铰接一个设有小手柄的盖子。倒油时，抓住提手，提起并倾斜油瓶。设有配重块的盖子会自动翻转，露出油嘴；或大拇指按压带小手柄的盖子，露出油嘴。倒完油，将油瓶置于台面上，它们油嘴上方的盖子都自动复位，倒油都较简单。但它们油嘴上方的盖子都只防尘，不密封；并且油瓶倒了，瓶内液体会流出来；再者提手占空间，不利于收纳，若收纳多个油瓶，多个提手在一起磕磕碰碰，很占空间，也不易摆放整齐。
目前市场上有种油瓶，瓶盖上设有油嘴和透气孔，此瓶盖上方还有个小瓶盖，保护油嘴。瓶身较细长，方便用手拿捏瓶身，不设提手。倒油时，一只手握住瓶身，另一只手将小瓶盖取下，露出油嘴，倾斜瓶身便可倒油。倒完油，再合上小瓶盖。整个过程需要双手操作。倒油时，油瓶倾斜，油嘴必须在透气孔下方，所以倒油第一步，确认手握瓶身的角度，稍有麻烦。此油瓶优点是密封性可以，没有提手，占用空间小，方便收纳。
以上油瓶共同缺点：由于油嘴设在瓶盖上，所以瓶内的油液必须漫过瓶口和带油嘴瓶盖连接处，漫过密封圈、油嘴根部；又因油液粘性较大，导致此盖子内壁、密封圈始终有积液，不能向下流回瓶内。当往油瓶里装油时，打开带油嘴的瓶盖，此时瓶盖内部的积液，便进入 此瓶盖和瓶口螺纹连接处；污染油瓶外壁、橱柜、桌面，也造成浪费，油瓶使用越久，这种污染和浪费更严重，并且形成油垢，影响人们健康；螺纹结构容易藏污纳垢，去除此处油污很难干净彻底，给人们清洁卫生增加难度和工作量；此积液还易造成瓶盖和瓶口螺纹连接打滑，拧不紧，导致密封圈密封失效，倒油时，瓶盖和瓶口连接处漏油；甚至导致在提起油瓶时，(瓶盖带有提手)，瓶盖和瓶口自行松脱，把装食用油的玻璃瓶打碎，油和玻璃渣撒一地或一桌，损失惨重。常有顾客在电商平台，反映这些问题。
目前市场上有种油瓶，瓶身侧壁设有油嘴、提手，瓶盖上没有油嘴、瓶盖不密封，如中国传统带嘴茶壶形状。倒油比较方便，只需单手抓住提手，倾斜瓶身，即可倒油。由于瓶内的油液不必漫过瓶口，到达瓶盖，所以瓶盖内壁没有积液。缺点是油嘴、瓶盖不易密封，油嘴容易滴漏油。再者油嘴和提手均凸出于瓶身外壁，占用空间大，不利于收纳。如用玻璃、陶瓷制作而成，其油嘴、提手很容易碰撞损坏。
目前市场上有种挤压式油瓶，瓶盖上设有油嘴，但没有透气孔，油嘴上还有个小瓶盖。倒油时，双手操作，一只手握住瓶身，再一只手打开小瓶盖，然后倒置油瓶，通过挤压弹性的瓶身，油液便从油嘴挤出，倒完油，再合上小瓶盖。缺点是瓶盖上没有透气孔等回收滴漏油装置，所以油嘴外壁的滴漏油，不能回收到瓶内，容易造成污染浪费。打开带油嘴的瓶盖，此瓶盖内壁和密封圈同样有积液，同样也会污染此瓶盖和瓶口螺纹连接处。

具体实施方式
实施例1：如图1-3所示，本实施例是一种瓶盖及具有该瓶盖的油瓶，瓶盖包括第一密封圈5、第一瓶盖6和倒油装置，该瓶盖与瓶身7组成油瓶。
具体特征是：第一瓶盖6上端面设有管体，此管体的孔为通孔，此管体内壁上端设有微小的环形凹槽或凸起，此管体内设有倒油装置。倒油装置上端始终位于第一瓶盖6上方，倒油装置下端始终位于第一瓶盖6下方。倒油装置中端在第一瓶盖6管体内上下移动，二者接触并留有空隙。第一瓶盖6底部设有第一密封圈5。第一瓶盖6下端侧壁设有螺纹，或卡合连接结构，并与瓶身7连接组成油瓶。当倒油装置移动至最高处，倒油装置卡紧瓶身7内壁，用于倒油；当倒油装置移动至最低处，倒油装置与第一瓶盖6相适配，用于密封。瓶身7可设有容量刻度，瓶身7用硬质不可变形材料制作，也可用弹性可挤压的变形材料制作。
所述的倒油装置包括第二瓶盖1、第二密封圈2、配重块3、活塞4、第三密封圈8、螺丝9。第二瓶盖1上端设有提手部，并始终位于第一瓶盖6上方，提手部设有通孔。第二瓶盖1颈部设有第二密封圈2，当倒油装置向下移动时，第二密封圈2能卡入第一瓶盖6管体内壁微小的环形凹槽或凸起，进行密封。或去除第二密封圈2，第二瓶盖1和第一瓶盖6管体直接卡紧密封。第二瓶盖1下端两侧设有向下凸起的支撑座。配重块3上端设有孔，此孔边沿设有半圆形的凸台，配重块3中端设有螺纹孔，配重块3底部设有小的凸点，两个配重块3特征相同。第二瓶盖1下端两侧支撑座与配重块3，采用螺丝9进行固定连接，也可粘接、铆接或卡接。由于配重块3和第二瓶盖1支撑座接触面是圆柱面，所以一个螺丝9就可固定一个配重块3。配重块3密度大，用于调整第二瓶盖1重心。活塞4为中空结构，顶端 设有出油孔，连通活塞4底部。图1所示，此出油孔端面为斜面，左边高右边低，方便向左边倾斜油瓶倒油。图1、图3所示，活塞4上端左侧壁设有细长的导油槽401。活塞4上端外侧壁设有对称的两个轴，轴的根部均设有四分之一圆形的凸台402。活塞4从下而上穿过第一瓶盖6管体，活塞4上端两侧的轴各插入一个配重块3上端的孔，进行铰接，并且二者的凸台配合，控制铰接的旋转幅度不能大于90度。或活塞4上端的轴改为孔，配重块3上端的孔改为轴，二者也可铰接。第二瓶盖1支撑座能与第一瓶盖6管体接触，并留有空隙。活塞4上端与第一瓶盖6管体内壁之间不接触，留有空隙。活塞4中端外壁设有4块支撑板403，支撑板403数量只要大于2个就行。活塞4中端依靠支撑板403，与第一瓶盖6管体内壁接触，并留有空隙。活塞4下端始终位于第一瓶盖6下方，活塞4下端截面尺寸大于第一瓶盖6管体孔径，活塞4中端的支撑板403连接活塞4下端，并设有台阶。弹性的第三密封圈8粘接在活塞4下端，并凸出于活塞4下端外侧壁。也可采用包胶工艺，即在合适的温度下将液态硅胶或者液态橡胶，直接注塑射粘到活塞4的下端，冷却后形成第三密封圈8，第一密封圈5、第二密封圈2也可采用包胶工艺制作。活塞4下端和第三密封圈8，均与第一瓶盖6管体下端面之间留有空隙。瓶身7采用硬质不可变形材料制作时，图1所示，第三密封圈8右外侧壁设有一个缺口，当倒油装置向上移动到一定位置，此缺口能与瓶身7的瓶颈内壁之间形成一个空隙，除此缺口以外的第三密封圈8外侧壁，均与瓶身7的瓶颈内壁贴合密封。图3所示，第三密封圈8右外侧便是缺口。瓶身7采用弹性可挤压变形材料制作时，第三密封圈8外侧壁可去除缺口，第三密封圈8能与瓶身7的瓶颈密封，不留一丝缝隙，并可去除控制活塞4和第二瓶盖1铰接旋转幅度的凸台。
实施例1的使用方法及原理：储油时，第一步往瓶内装油，先确定第一瓶盖6和第二瓶盖1是合上密封的，如果没合上，将油瓶置于桌面上，由于配重块3重心偏下，使得第二瓶盖1提手部自动回到油瓶正上方，按压第二瓶盖1提手部，第二密封圈2与第一瓶盖6管体内壁卡紧密封。或直接拿捏第二瓶盖1塞紧第一瓶盖6管体。拧开第一瓶盖6与瓶身7的螺纹连接，捏住第一瓶盖6，从瓶身7中拔出活塞4，从瓶口灌入一定量的食用油。瓶内液面控制在图1所示活塞4的下方。再将第一瓶盖6与瓶身7合上拧紧，便可储藏食用油。
采用硬质不可变形材料制作瓶身7的油瓶倒油时，一根手指插入第二瓶盖1提手部的通孔，向上提起油瓶。由于瓶身7加上食用油的重量，若玻璃制作的瓶身7重量一般都超250克，还有迅速向上提油瓶的运动惯性，所以第二瓶盖1与第一瓶盖6轻松分离。若第二瓶盖2密封效果设计比较紧，可以一根手指插入第二瓶盖1的通孔，其余手指按压第一瓶盖6上端面，即可分离。第二瓶盖1下端支撑座和活塞4中端均与第一瓶盖6管体内壁接触，并且间隙配合，移动阻力很小。当第二瓶盖1下端支撑座还未完全脱离第一瓶盖6管体内壁时，活塞4中端支撑板403就进入第一瓶盖6管体内壁，进行支撑定位。紧接着第三密封圈8滑入、卡紧在瓶身7瓶颈处，二者属于过盈配合。再者第三密封圈8上端面有弧度，致使倒油装置向下移动的阻力大于向上移动的阻力。再者整个倒油装置重量不到100克。所以此时将油瓶置于桌面上，手指放开第二瓶盖1提手部，倒油装置不会向下滑落。接着单手握起瓶身7，朝图1所示的油瓶左侧慢慢倾斜。由于配重块3作用，第二瓶盖1会自动旋转，露出活塞 4出油孔。又由于活塞4和配重块3之间的凸台配合，控制铰接的旋转幅度，朝右侧倾斜油瓶，第二瓶盖1则不会旋转，方便确定倒油方向。当活塞4出油孔向左侧出油时，瓶外空气依次通过第一瓶盖6管体和活塞4之间空隙，第三密封圈8右侧的缺口，进入瓶内，使倒油不抖动，流量平稳。倒油时，瓶内液面一般不会漫过第三密封圈8缺口，即使漫过，此缺口处液面会有气泡，即向瓶内进气。第二瓶盖1上端也可设有标记，方便确定倒油方向。提手部设置在油瓶顶端，不占空间，方便油瓶收纳，方便从密集存放的瓶瓶罐罐中，轻易选择并向上提起一个油瓶。
采用弹性可变形材料制作瓶身7的油瓶倒油时，第三密封圈8外侧壁无缺口。将第二瓶盖1拔出至最高处，倾斜或倒置油瓶，直接挤压瓶身7即可，此油瓶还可装半流体的酱汁。
倒油结束，不管瓶身7材质如何，油瓶都自动进行滴漏油回收。即油瓶不再倾斜或倒置，恢复原位放置。活塞4上端外壁可能有少量残存油，在重力作用下，直接顺着活塞4外壁流下去。活塞4上端与第一瓶盖6管体内壁不接触，活塞4中端和第一瓶盖6管体内壁接触，接触面只在此管体下端，并有一定的空隙。所以残存油很容易通过第一瓶盖6管体，到达第三密封圈8，通过第三密封圈8缺口，一直流下去。活塞4下端也可设有坡度，加快其流动速度。一般倒油结束，(参照前文储油。)按压第二瓶盖1提手部，第三密封圈8与瓶身7的瓶颈内壁脱离接触，形成间隙，更加方便油液往下流动。活塞4上端左侧导油槽401，是为方便收集出油孔残存油，进入导油槽401，更快流下去，减少对活塞4上端两侧铰接机构的污染。配重块3底部小的凸点，也是为让残存油更快滴下去。
不管瓶身7材质如何，第一瓶盖6和瓶身7螺纹连接处不漏油，无积液的原因总结如下：储油时，不管打开与合上第一瓶盖6，第三密封圈8只和瓶身7内壁接触。不会向瓶身7与第一瓶盖6螺纹连接处，提供食用油。当打开第一瓶盖6，向瓶外拔活塞4时，第二瓶盖1和第一瓶盖6是合上的，握住第一瓶盖6往外拔，第三密封圈8到达瓶身7的瓶颈处，倾斜活塞4，并继续往外拔，使第三密封圈8只有两点与瓶身7的瓶颈内壁接触，接触越少，污染越少。当完全拔出活塞4时，第三密封圈8已经远离第一瓶盖6螺纹处。(另外瓶身7瓶口内径，也可略大于瓶颈内径，在取出活塞4时，第三密封圈8与瓶口内壁不接触，效果更好。)当向瓶内塞入活塞4时，同样第二瓶盖1和第一瓶盖6先合上，捏住第二瓶盖1，将活塞4倾斜着塞入瓶内。第一瓶盖6与瓶身7即将螺纹连接时，再将活塞4摆正。若瓶口附着少量油，需要擦除的话，也很方便。再者储油时，不管倒油装置位置，将瓶内液面始终控制在其下方，第三密封圈8上端面就很少有油。倒油时，第三密封圈8有弧度的上端面，与瓶身7的瓶颈处，形成一定角度的夹角，此处能吸住一定量的油，此处的油不向第一密封圈5流动；同时第一瓶盖6的管体下端面与活塞4间隙很小，阻挡滴漏油流向第一密封圈5。综上所述，各种办法保证第一密封圈5无积液，即保证第一瓶盖6与瓶身7连接处无积液、无油垢、不漏油，二者连接牢固，不打滑，避免了污染浪费，干净卫生。
实施例2：如图4-6所示，本实施例是一种瓶盖及具有该瓶盖的油瓶，瓶盖包括第一密封圈5、第一瓶盖6和倒油装置，该瓶盖与瓶身7组成油瓶。
具体特征是：第一瓶盖6上端面设有管体，此管体内孔为变径，即管体下端口径大于管 体上端口径，此管体内设有倒油装置；第一密封圈5设置在第一瓶盖6底部，同时也位于瓶身7的瓶口处，第一瓶盖5与瓶身7螺纹连接。
所述的倒油装置包括第二瓶盖1、第二密封圈2、配重块3、活塞4、第三密封圈8。两个配重块3上端均设有通孔，通孔边沿为整圆的凸台。活塞4上端两侧设有对称的轴，轴均与配重块3上端通孔铰接。活塞4上端外壁，靠近轴的位置，设有对称的方形凸台402，凸台402也可为半圆形，凸台402与固定配重块3并凸出于配重块3表面的螺丝9配合，控制铰接旋转幅度。图4所示，朝右侧倾斜油瓶，凸台402抵住螺丝9，第二瓶盖1不旋转。活塞4中端设有3个支撑板403，活塞4中端依靠支撑板403与第一瓶盖6管体下端内壁接触，并留有空隙。第一瓶盖6管体与支撑板403配合，限制活塞4向上移动的高度，并使得活塞4下端与第一瓶盖6管体下端面之间，留有空隙。第二瓶盖1下端两侧支撑座和第二密封圈2，只能与第一瓶盖6管体上端内壁接触，减少油液污染第二瓶盖1的概率。其余技术特征均与实施例1的技术特征相同。
实施例2的使用方法及原理与实施例1的使用方法及原理相同。
实施例3：如图7-10所示，本实施例是一种瓶盖及具有该瓶盖的油瓶，瓶盖包括第一密封圈5、第一瓶盖6和倒油装置，该瓶盖与瓶身7组成油瓶。
具体特征是：第一瓶盖6上端面设有管体，此管体下端面开槽若干，此管体内设有倒油装置。第一瓶盖6底部设有“Z”形截面的第一密封圈5，此密封圈紧贴瓶身7的瓶口内壁和第一瓶盖6管体外壁，进行密封。
所述的倒油装置包括第二瓶盖1、第二密封圈2、配重块3、活塞4、螺丝9、第三密封圈8。第二瓶盖1下端两侧支撑座能轻微变形，活塞4上端的轴直接卡入第二瓶盖1下端支撑座的孔，进行铰接。活塞4上端的轴根部，设有异形的凸台402，图7所示，此凸台402左侧和底部呈90度夹角，二者之间圆弧面过度，配重块3顶部为平面。与异形的凸台402左侧和底部配合，控制铰接的旋转幅度不大于90度。活塞4中端截面为方形或多边形，能与第一瓶盖6圆形截面的管体内壁接触，并留有空隙。活塞4下端能与第一瓶盖6下端面接触，也留有空隙。其余技术特征均与实施例1的技术特征相同。第一瓶盖6的管体也可变径，如实施例2一样。第一瓶盖6管体下端截面也可为方形或多边形的内壁，与活塞4中端截面为圆形外壁接触，二者之间同样形成空隙，第一瓶盖6管体上端截面为圆形的内壁，并与第二密封圈2接触，进行密封。
实施例3的使用方法及原理与实施例1的使用方法及原理相同。
实施例4：如图11所示，本实施例是对实施例3的配重块3进行改进。一种瓶盖及具有该瓶盖的油瓶，包括本实施例的配重块3和实施例3的部分技术特征。
具体特征是：去除实施例3两个配重块3和活塞4上端两侧的凸台402，本实施例其余技术特征均与实施例3技术特征相同。本实施例的配重块3，可理解为将实施例3的两个配重块3，在图7所示活塞4左侧位置，连接成为一个“U”形配重块3，此“U”形配重块3同样设置在实施例3的第二瓶盖1下端支撑座上，用螺丝9固定连接，也可粘接、铆接或卡接。此“U”形配重块3中间部位，与图7所示活塞4左侧壁接触，控制铰接旋转幅度，即第二瓶 盖1不能向图7所示油瓶左侧旋转。实施例1、实施例2的配重块3也可同样合二为一，成为一体的“U”形配重块3。
实施例4的使用方法及原理与实施例1的使用方法及原理相同。
实施例5：如图12-13所示，本实施例是对实施例1的倒油装置上端部位改进，一种瓶盖及具有该瓶盖的油瓶，包括本实施例特征和实施例3的部分技术特征。
具体特征是：所述的倒油装置包括第二瓶盖1、第二密封圈2、配重块3、活塞4、第三密封圈8、螺丝9、提手10。第二瓶盖1上端与提手10，用螺丝9固定连接，也可粘接、铆接或卡接，形成提手部。提手10的通孔，即是提手部的通孔。活塞4上端两侧的轴，直接卡入第二瓶盖1下端两侧支撑座的孔，进行铰接。配重块3与第二瓶盖1支撑座铆接固定。第二瓶盖1底部中心设有凸台，此凸台能与活塞4顶部出油孔的斜面接触，控制铰接的旋转幅度。图中省略未画的技术特征均与实施例1的技术特征相同。
实施例5的使用方法及原理与实施例1的使用方法及原理相同。
实施例6：如图14-17所示，本实施例是一种瓶盖及具有该瓶盖的油瓶，瓶盖包括第一密封圈5、第一瓶盖6和倒油装置，该瓶盖与瓶身7组成油瓶。
具体特征是：第一瓶盖6上端面设有管体，此管体下端面开槽若干，此管体内设有支架，此支架中心设有通孔，此支架中心孔周围与管体内壁之间，设有若干通孔，透气不存油。此支架中心孔内设有倒油装置，倒油装置中端在此支架中心孔内上下移动。倒油装置上端始终位于第一瓶盖6上方，倒油装置下端始终位于第一瓶盖6下方。第一瓶盖6底部设有第一密封圈5，第一瓶盖6和瓶身7连接。
所述的倒油装置包括第二瓶盖1、第二密封圈2、配重块3、活塞4、第三密封圈8、螺丝9。第二瓶盖1下端两侧支撑座均设有两个通孔，其下方的孔均与配重块3下端铆接，或过盈配合固定。两个配重块3上端均设有通孔，通孔一侧均设有半圆的台阶。活塞4上端两侧对称设有凸台，凸台均设有螺纹孔。螺丝9为半牙螺丝，螺丝9依次穿过第二瓶盖1两侧支撑座上方的孔、配重块3的孔，拧入活塞4上端两侧凸台的螺纹孔，完成铰接。活塞4上端两侧凸台边沿设有四分之三圆的台阶，此台阶与配重块3半圆的台阶配合，控制铰接的旋转幅度不能大于90度。活塞4上端与第一瓶盖6管体不接触，留有空隙。活塞4始终与第一瓶盖6管体内的支架中心孔接触，留不留有空隙皆可。因此第二瓶盖1支撑座外侧壁，和第一瓶盖6管体内壁也可不接触。活塞4中端与第一瓶盖6支架中心孔截面均为扁形或方形或椭圆形，二者接触配合，不让活塞4沿自身轴线旋转。当活塞4向下移动，活塞4中端脱离此支架中心孔之前，两个配重块3就会进入第一瓶盖6管体，配重块3平面的一侧与此管体内的支架接触，不让活塞4沿自身轴线旋转，接着活塞4上端两侧凸台卡入此支架凹槽，同样不让活塞4沿自身轴线旋转。图15所示，第一瓶盖6管体内的支架上端设有凹槽，目的是为了尺寸紧凑。也可向上加高第一瓶盖6管体和活塞4上端尺寸，管体内的支架高度不变，便能去除支架上端凹槽。加高到配重块3接触不到第一瓶盖6管体内的支架时，此支架中心孔和活塞4中端截面也可为圆形，活塞4可以沿自身轴线旋转。第一瓶盖6管体的下端面与其内部支架下端面平齐，所以此管体下端面开槽若干，使活塞4下端与此管体下端面之间留 有空隙。第三密封圈8外侧与瓶身7的瓶颈内壁贴合密封，不留一丝缝隙。图14所示，第三密封圈8与活塞4下端右侧连接处，设有一个小的透气孔，实现和实施例1第三密封圈8外侧壁缺口的相同功能。此透气孔也可设在第三密封圈8或活塞4上，不过都没有第三密封圈8外侧壁设置缺口的效果好。其余技术特征均与实施例1的技术特征相同。
实施例6的使用方法及原理与实施例1的使用方法及原理相同。
实施例7：如图18-19所示，本实施例是一种瓶盖及具有该瓶盖的油瓶，瓶盖包括第一瓶盖6和倒油装置，该瓶盖与瓶身7组成油瓶。
具体特征是：第一瓶盖6底部设有一圈与瓶身7的瓶口内壁贴合密封的凸台，此凸台和矿泉水瓶盖的密封技术特征相同。第一瓶盖6上端面设有管体，此管体内孔截面形状为非圆形，例如方形、椭圆形，此管体内设有倒油装置。第一瓶盖6和瓶身7螺纹连接。
所述的倒油装置包括第二瓶盖1、第二密封圈2、活塞4、第三密封圈8。第二瓶盖1下端两侧支撑座设有孔，此孔与活塞4上端两侧的轴，进行铰接。或第二瓶盖1下端两侧支撑座设有轴，此轴与活塞4上端两侧的孔，进行铰接。此倒油装置也可设有控制铰接旋转幅度的凸台或台阶。活塞4中空，其顶部设有多个出油孔，连通活塞4底部。第三密封圈8卡入活塞4下端外侧壁凹槽，第三密封圈8外侧与瓶身7的瓶颈内壁贴合密封，不留一丝缝隙。图18所示，第三密封圈8右侧设有透气孔，此孔与活塞4下端右侧的缺口相通，实现和实施例1第三密封圈8外侧壁缺口的相同功能。当瓶身7为弹性可挤压变形材料制作，第三密封圈8透气孔和活塞4缺口安装位置错开，或第三密封圈8没有缺口和透气孔。其余技术特征均与实施例1的技术特征相同。
实施例7的使用方法及原理与实施例1的使用方法及原理有一处区别，其余相同。即本实施例需要用手控制第二瓶盖1旋转角度，依靠第二瓶盖1两个支撑座的夹紧力，或其铰接处的摩擦阻力，使得当第二瓶盖1旋转到一定角度，松开与第二瓶盖1接触的手，第二瓶盖1的旋转角度保持不变。
实施例8：如图20所示，本实施例是一种瓶盖及具有该瓶盖的油瓶，瓶盖包括第一密封圈5、第一瓶盖6和倒油装置，该瓶盖与瓶身7组成油瓶。
具体特征是：第一瓶盖6上端面设有管体，此管体内设有倒油装置。第一瓶盖6底部设有第一密封圈5，第一瓶盖6和瓶身7螺纹连接。
所述的倒油装置包括第二瓶盖1、第二密封圈2、活塞4、第三密封圈8、提手10、销钉11。第二瓶盖1提手部设有通孔，即“C”形提手10卡入第二瓶盖1上端侧壁孔，二者合起来形成通孔结构。第二瓶盖1底部与活塞4顶部之间，用销钉11固定连接，也可采用粘接、焊接、卡接或螺丝连接。第二瓶盖1颈部和活塞4上端侧壁均设有通孔，销钉11穿过二者的通孔，再将第二密封圈2套在第二瓶盖1颈部，第二密封圈2不让销钉11松脱。第二瓶盖1下端没有支撑座与活塞4铰接。活塞4上端左侧壁设有出油孔，出油孔与第一瓶盖6管体不接触。除了出油孔下方支撑板403，其余活塞4中端支撑板403均凸出于第一瓶盖6上端面；或所有支撑板403避开出油孔，凸出于第一瓶盖6上端面；或所有支撑板403不凸出于第一瓶盖6上端面，保留第二瓶盖1下端两侧支撑座，卡在活塞4上端外侧，与第一瓶盖6管体 接触。销钉11和提手10也可合二为一，即活塞4上端侧壁孔与第二瓶盖1安装提手10的侧壁孔轴线重合，提手10能同时卡入二者的侧壁孔，第二密封圈2设置在活塞4侧壁孔和出油孔之间的外侧壁即可。其余技术特征均与实施例1的技术特征相同。
实施例8的使用方法与实施例1的使用方法相同，工作原理有一处区别，即本实施例第二瓶盖1无需旋转，只要拔出第二瓶盖1，出油孔便自然露出。
实施例9：如图21-22所示，本实施例是一种瓶盖及具有该瓶盖的油瓶，瓶盖包括第一密封圈5、第一瓶盖6和倒油装置，该瓶盖与瓶身7组成油瓶。
具体特征是：第一瓶盖6上端面设有管体，此管体下端内壁设有支架，此支架中心设有通孔，此支架中心孔周围与管体内壁连接处，设有若干通孔，透气不存油。此支架中心孔内设有倒油装置。第一瓶盖6底部设有第一密封圈5，第一瓶盖6和瓶身7螺纹连接。
所述的倒油装置包括第二瓶盖1、第二密封圈2、活塞4、第三密封圈8。第二瓶盖1提手部侧面设有凹槽，为非通孔提手结构。非通孔提手结构还包括盲孔、凸台、球体，任选其一，只要能拿捏、手提即可。但在使用时，不如设有通孔的提手部，单手操控性能好。(参照前文使用方法及原理。)第二瓶盖1底部与活塞杆404顶部螺纹连接，活塞杆404中空，连通底部，侧壁设有出油孔。活塞本体405为有坡度的圆片状结构，中间设有通孔，活塞本体405和活塞杆404铆接组成活塞4，二者也可粘接、焊接、卡接、螺纹连接、螺丝连接。第三密封圈8套在活塞本体405外侧壁上。其余技术特征均与实施例6的技术特征相同。
实施例9的使用方法及原理与实施例7的使用方法及原理相同。
实施例10：如图23-24所示，本实施例是一种瓶盖及具有该瓶盖的油瓶，瓶盖包括第一密封圈5、第一瓶盖6和倒油装置，该瓶盖与瓶身7组成油瓶。
具体特征是：第一瓶盖6上端面设有管体，此管体内设有支架，此支架截面和实施例9的支架截面特征相同。此支架中心设有通孔，此支架中心孔内设有倒油装置。第一瓶盖6底部设有第一密封圈5，第一瓶盖6和瓶身7螺纹连接。
所述的倒油装置包括第二瓶盖1、第二密封圈2、活塞4、第三密封圈8、油嘴12。活塞4中空，其上端侧壁设有孔，连通活塞4底部。活塞4从下而上穿过第一瓶盖6管体内的支架中心孔，活塞4顶端与第二瓶盖1底部铆接固定，也可粘接、焊接、螺纹连接、螺丝连接、销钉连接或卡扣连接。第二瓶盖1下端没有支撑座。第一瓶盖6管体内的支架下端面凸出于第一瓶盖6管体下端面，加上活塞4下端设有坡度，使得活塞4下端和第三密封圈8，均与第一瓶盖6管体下端面之间留有空隙。油嘴12为弯管状，中间为通孔，由弹性的软质材料制成，油嘴12下端卡紧在活塞4底部孔中，油嘴12上端在活塞4侧壁孔中伸出，油嘴12下端一侧凸出与活塞4底部，是为了方便拔出油嘴12，油嘴12与第一瓶盖6管体内壁不接触。其余技术特征均与实施例1的技术特征相同。
实施例10的使用方法和实施例1相同，工作原理有两处区别。即拔出第二瓶盖1至最高处，依靠油嘴12材料弹性，将油嘴12上端自动弹出，进行倒油。按压第二瓶盖1提手部时，油嘴12上端在第一瓶盖6管体内的支架上端口约束下，进入活塞4侧壁孔，进行储油。另外由于第二瓶盖1和活塞4不是铰接，所以倒油将第二瓶盖1拔出至最高处，插入提手部通孔 的手指也可不用拔出，其余手指握住瓶身7，朝油嘴12弹出方向，倾斜油瓶即可。
实施例11：如图25所示，本实施例是一种瓶盖及具有该瓶盖的油瓶，瓶盖包括第一密封圈5、第一瓶盖6和倒油装置，该瓶盖与瓶身7组成油瓶。
具体特征是：第一瓶盖6上端面设有管体，此管体内设有支架，此支架中心设有通孔，此支架中心孔周围与管体内壁连接的凹部，设有若干通孔，透气不存油。此支架中心孔内设有倒油装置。倒油装置包括第二瓶盖1、第二密封圈2、活塞4、第三密封圈8、油嘴12。第二瓶盖1下端设有管体，此管体侧壁设有孔，连通底部。油嘴12为弯管状，油嘴12下端卡紧在第二瓶盖1管体底部孔中，油嘴12上端能在第二瓶盖1管体侧壁孔中伸缩自如。第二瓶盖1管体穿过第一瓶盖6管体内的支架中心孔，并与活塞4螺纹连接，也可焊接、粘接、铆接或卡接。活塞4为有坡度的圆片状结构，中心设有通孔，并与第二瓶盖1底部孔连通。活塞4和第二瓶盖1连接的同时，将油嘴12下端夹的更紧。第二密封圈2和第一瓶盖6管体依靠磁性，能吸在一起，进行密封。其余技术特征均与实施例10的技术特征相同。
实施例11的使用方法及原理与实施例10的使用方法及原理相同。
实施例12：如图26-29所示，本实施例是一种瓶盖及具有该瓶盖的油瓶，瓶盖包括第一密封圈5、第一瓶盖6和倒油装置，该瓶盖与瓶身7组成油瓶。
具体特征是：第一瓶盖6上端面设有管体，此管体内孔设有变径，即管体下端口径大于管体上端口径，此管体下端面为波浪型或开槽若干，此管体内设有倒油装置。第一瓶盖6底部设有第一密封圈5，第一瓶盖6和瓶身7螺纹连接。
所述的倒油装置包括第二瓶盖1、第二密封圈2、配重块3、活塞4、第三密封圈8、油嘴12。第二瓶盖1下端两侧设有向下凸起的支撑座，并与两个配重块3卡接固定。即第二瓶盖1的两个支撑座设有用于卡接的小孔和沟槽，图28所示，支撑座截面呈“C”型。图27所示，两个配重块3下端一侧均设有楔形凸台，此楔形凸台卡入第二瓶盖1支撑座的小孔，完成卡接。(或第二瓶盖1的两个支撑座下端侧壁设有凸台，并与配重块3侧壁设有的小孔或者凹槽配合，完成卡接；或两个支撑座下端侧壁设有凸台，并与配重块3的下端面配合，完成卡接。)两个配重块3下端靠近活塞4的一侧，设有小的凸起或凹槽，为了方便拆卸配重块3。两个配重块3上端均设有轴，此轴均插入活塞4上端两侧的孔，完成铰接。活塞4上端两侧孔的边沿设有凸台402，凸台402与配重块3上端面配合，控制铰接的旋转角度不能大于90度。图26所示，活塞4为中空结构，上下连通，其顶端出油孔轴线偏向左边，与其底端孔的轴线不重合，为了方便倒油；油嘴12下端卡紧固定在出油孔内，油嘴12为薄壁短管结构，中间是通孔，其上端面为斜面，左高右低，并且左边沿口凸出外翻，是为了方便向左边倾斜油瓶倒油。用硬质材料制作油嘴12，如不锈钢，其壁厚能薄至0.1毫米，壁厚越薄，越能减少滴漏油现象发生，也可用弹性材料制作油嘴12，如硅胶。油嘴12和活塞4也可成为一个整体零件。同样前文实施例中的活塞4上端出油孔，也可设有油嘴12。图27所示，油嘴12剖面和活塞4剖面画在一个平面上，是为了便于观察。活塞4中端设有4块支撑板403，依靠支撑板403，活塞4中端只能与第一瓶盖6管体下端内壁接触，并留有空隙，第二瓶盖1的支撑座只能与第一瓶盖6管体上端内壁接触，为了减少油液污染第二瓶盖1的概率。活塞 4下端设有第三密封圈8，活塞4下端和第三密封圈8，均与第一瓶盖6管体下端面之间留有空隙，第三密封圈8还能与第一瓶盖6管体下端面接触，起到缓冲减震和限位作用。第二瓶盖1底部设有一个或多个片状的凸台101，它也可为柱状或管状。油瓶盛装某些水溶性液体，如酱油，倒酱油时，若非常迅速地向上提拔第二瓶盖1，油嘴12和活塞4孔内若有少量酱油，则有可能向凸台101泼溅一些酱油，凸台101上的酱油汇集多了，便滴落至油嘴12孔内或活塞4上。凸台101也可与油嘴12接触，如同实施例5控制铰接旋转幅度的凸台。其余技术特征均与实施例1的技术特征相同。
实施例12的使用方法及原理与实施例1的使用方法及原理相同。
