Description

一种液体的定量方法及定量瓶 技术领域
本发明涉及液体包装容器的技术领域，更具体地，涉及一种液体的定量方法及定量瓶。
 背景技术
人们在生活中有时需要定量使用液体，尤其是一些生活精细的人们对量的要求更为严格，对日常生活中的液体、调料等都严格控制用量，而对液体的量通常采用量取器具或涉及液体定量或半定量的包装容器来定量。
其中，量取器具如用量筒、量杯等量具量取，或使用具有刻度的液体容器倒取等，但是用量具量取需要量具二次传递，可能或造成二次污染，量取使用不方便，且肉眼误差等问题还会影响用量的准确性。
而涉及液体定量或半定量的包装容器，主要包括以下几种定量方式：一、挤压瓶加定量盖的定量方式，这种方式在使用时需要垂直挤压量取，然后倒出，不符合使用习惯，非常不便；二、倾倒式定量瓶盖定量方式，这种方式要求使用时翻转180度，对操作要求高，可控性差，也无法适应特殊的场景，比如，不能将洗涤剂倒进波轮洗衣机的洗涤剂槽；三、局部形变定量方式，这种方式的挤出量较小，且挤出量不可控。因此，现有技术的定量或半定量包装容器存在不同程度的缺陷。
 技术问题
本发明旨在克服上述现有技术存在不符合消费者使用习惯，或可控性较差，或不能适应不同使用场景的问题，提供一种液体的定量方法及定量瓶，通过结构限位进行识别挤出量，达到定量取液的目的，且不需要特殊控制，适应各种使用场景，符合用户的挤压瓶体取液习惯。
 技术解决方案
本发明采取的技术方案是，一种液体的定量方法，包括用于盛放液体的容器，容器上设有液体出口，所述容器在被按压时，发生形变，且所发生的形变量使容器内的液体从容器出口挤出；通过限制容器被按压时所发生的形变量，使液体的挤出量为定量。
本技术方案的定量方法，通过限制容器被按压时所发生的形变量，从而控制液体的挤出量，使液体的挤出量为定量。本技术方案的定量方法简单、方便，且可控性好，适应于各种按压定量瓶，符合消费者的使用习惯。
进一步地，所述容器的两内侧壁上至少设有一对凸起，所述凸起的底部朝向容器的内腔，且两凸起之间设有按压间距，通过设置按压间距的大小来确定容器被按压时所发生的形变量，使液体的挤出量为定量。
本技术方案中，通过在容器的内腔设置凸起，且凸起间设有按压间距，在按压容器时，两凸起碰触，从而挤出容器内液体，且两凸起碰触抵压，起到了限制容器变形量的效果，通过限制容器的形变量，从而使液体的挤出量为定量。
进一步地，所述容器的内腔设有限制件，所述限制件悬空设置于容器的内腔，且对应于容器被按压的位置，所述限制件与容器内壁之间设有按压间距，通过设置限制件，限制容器被按压时所发生的形变量，使液体的挤出量为定量。
本技术方案通过在容器的内腔设置限制件，限制容器被按压时所发生的形变量，同样能达到控制液体的挤出量为定量的效果。
其中，所述限制件设置容器内腔的中线上，限制件与容器被按压的侧壁之间的距离一致，从而达到更好的按压效果和挤出效果。
进一步地，还可通过同时设置凸起和限制件限制容器被按压时所发生的形变量，所述凸起设置于容器被按压位置的两内侧壁，所述限制件悬空设置于容器的内腔，且对应于容器被按压的位置，所述凸起与限制件之间设置按压间距，在按压容器时，所述凸起与限制件接触。
进一步地，所述容器为按压面呈弧面的扁形瓶体，且容器上被按压的位置，对应于人手握瓶时，手指所接触的容器外壁的位置。
本技术方案的瓶体设计，具有按压力小且容易复原的效果，同时，还更便于人们提拿并进行按压出液。
一种定量瓶，包括瓶体和瓶盖，所述瓶体在被按压时，发生形变，且所发生的形变量使瓶体内的液体从瓶盖上挤出；所述瓶体的内腔设有凸起，所述凸起分别设于瓶体的两内侧壁，两凸起之间留有按压间距，用于确定瓶体被按压时所发生的形变量，通过按压瓶体，使两凸起碰触，从而定量挤出瓶体内的液体。
本技术方案中，在瓶体的内腔且对应按压位的位置处设置了至少一对凸起，形成按压时的限位机构。当瓶体被按压时，向内形变，直到内腔的两个凸起接触，并限制瓶体进一步变形，从而获得受控制的变形量，变形时压缩的瓶体空间与液体的挤出体积正相关。
其中，瓶体的按压位置设置在瓶体正面和背面的侧壁中线的区域。
进一步地，瓶体的按压位置还对应于人手握瓶时，手指接触瓶体的位置。
本技术方案的定量瓶尤其适用于需要定量取用，且一次取量较大的液体包装容器，如液体洗涤剂、个人护理品或液体调味剂等。
进一步地，所述瓶体的两外侧壁设有凹位，所述凹位的开口朝向瓶体外侧壁，凹位的底部朝向瓶体的内腔凹陷，从而在瓶体的内腔形成所述凸起。
本技术方案中，定量瓶内腔所形成的凸起通过瓶体的两外侧壁向内凹陷形成，凹陷的位置在瓶体的两外侧壁形成凹位，这样的结构简单，可以通过模具结构设计为与瓶体一体成型，以便大规模生产。
其中，所述凸起与瓶体一体成型。
进一步地，所述瓶体的外侧壁上设有补平部件，所述补平部件可拆卸设置在凹位上，用于填平凹位，使瓶体的外侧壁完整。
本技术方案中，通过设置补平部件，使瓶体的外形更美观，且便于用户在该位置按压，挤出瓶内液体。
其中，所述补平部件根据装配方式的不同可以采用单片式或两片相连式的结构；其中，单片式的补平部件更适合于设备自动装备，通过胶黏剂或简易结构固定于瓶体的凹位，同时还可以连同瓶体表面覆盖的标签一起固定。两片相连式的补平结构可先扣合固定于两凹位，再通过标签覆盖瓶体表面进行进一步的固定。
进一步地，所述补平部件与凹位一一对应设置。
进一步地，所述补平部件的表面设有识别区，用于指示瓶体的按压区域。
本技术方案中，设置识别区以便于用户更快更准确地找到按压位置。
其中，补平部件的表面可设置一些触摸识别的信息以作为识别区，如小凸点、凹点、纹理或小孔等。
进一步地，所述补平部件的表面通过往内凹陷形成所述识别区，同时利于用户轻松抓握挤压。
进一步地，所述凸起的底部朝向瓶体的内腔，凸起的顶部朝向瓶体的外壁，且凸起底部的尺寸小于凸起顶部的尺寸，利于瓶子的生产工艺，保证瓶子的质量稳定。
进一步地，在通过凸起中心的瓶体横截面上，凸起顶部的尺寸小于瓶体截面外径尺寸的3/5，所述凸起的深度由瓶体的形状及其形变对应的空间压缩量决定，为获得明确的按压瓶体的反馈和必要的挤出量，凸起的按压间距大于5mm。
进一步地，所述补平部件呈单U型或双U闭环型结构设计。
进一步地，所述补平部件包括与瓶体的凹位对应设置的挂耳和连接挂耳的连接带，且挂耳分别可拆卸设置于瓶体的凹位上。
其中，所述挂耳的中心内陷，且内陷的程度小于凹位内陷的程度。
进一步地，所述瓶体的侧壁上设有内陷的连接位，且连接位的两端分别连接至瓶体正面和背面的凹位，所述连接带可拆卸嵌合设置于连接位上；所述凹位与连接位在瓶体上形成的形状与所述挂耳和连接带的形状匹配。
作为另一种实施方案：一种定量瓶，包括瓶体和瓶盖，所述瓶体的外侧壁上至少设有两个第一凹位，两第一凹位朝向瓶体的内腔凹陷，用于限制瓶体被按压时所发生的形变量，且两第一凹位的底部之间设有按压间距，通过按压瓶体，使两个第一凹位的底部接触，从而定量挤出瓶内的液体；所述第一凹位内还设有第二凹位，所述第二凹位的开口方向朝向瓶体内腔。
进一步地，所述第一凹位底部的尺寸小于第一凹位开口面的尺寸，所述第二凹位底部的尺寸小于第二凹位开口面的尺寸，同时还小于第一凹位开口面的尺寸。
进一步地，所述第二凹位的开口面边缘与第一凹位的底部相连，所述第二凹位的底部与第一凹位的开口面边缘之间留有间隙。这样的结构简单，可以通过模具结构设计为与瓶体一体成型，以便大规模生产。
进一步地，所述第二凹位的开口面边缘与第一凹位的底部相连，且相连的位置形成瓶体被按压时的受力部位。
进一步地，所述第二凹位的底部形成瓶体被按压时的按压位。
其中，所述第二凹位的开口面与第一凹位的底部相平，且第二凹位开口面的尺寸小于或等于第一凹位底部的尺寸。所述第二凹位的底部与第一凹位的开口面相平。
作为另一种实施方案：一种定量瓶，包括瓶体和瓶盖，所述瓶盖上设有出液口，且出液口连接有一吸管，所述吸管从瓶盖延伸至瓶体的底部，所述吸管上设有限制件，所述限制件设在瓶体内腔，且对应于瓶体被按压的位置，所述限制件与瓶体的内侧壁之间设有按压间距，用于确定瓶体被按压时所发生的形变量，通过按压瓶体，使限制件与瓶体内侧壁接触，从而挤出定量的液体。
本技术方案中，所述限制件设在瓶体的内腔，且对应于按压瓶体的位置，当瓶体被按压时，瓶体发生形变，瓶体内的液体被吸管吸入，再从瓶盖上的出液口挤出；由于限制件限制了瓶体的形变量，即瓶体的压缩空间一定，从而使挤出的液体定量。瓶体变形时压缩的瓶体空间即为液体的挤出体积。
进一步地，所述瓶体的侧壁且往内腔方向设有第一凹位，所述第一凹位设于与限制件相对的位置上，且第一凹位与限制件之间设有按压间距，在按压瓶体时，所述限制件与第一凹位触碰，限制瓶体的形变量，从而控制挤出定量的液体。
作为另一种实施方案：一种定量瓶，包括瓶体和瓶盖，所述瓶体用于盛放液体且瓶内液体通过按压瓶体的瓶身出液，所述瓶体的内腔设有限制件，所述限制件与瓶身被按压的位置对应，且与瓶身被按压的位置之间设有按压间距。
进一步地，所述瓶体的内腔设有连杆，所述连杆的一端与限制件连接，另一端与瓶盖连接，或固定于瓶口的位置。
其中，连杆与限制件可设计为一体成型，也可设计为可拆卸连接。其中，连杆与限制件可拆卸连接时，限制件上设有凹槽，连杆上设有用于插接到凹槽固定的凸沿，从而使得连杆固定于限制件上。
进一步地，所述连杆与限制件的连接位置形成舌状结构，且所述舌状结构具有弹性。
本技术方案中，所述连杆与限制件的连接位置形成舌状结构，在将限制件和连杆一同塞入瓶口时，连杆可以通过舌状结构变形倾斜，从而改变连杆与限制件的位置关系，如将连杆与限制件由原来的垂直关系变形倾斜为小于直角的角度，使限制件和连杆能顺利进行进入瓶体内腔。限制件和连杆整体进入瓶体后，通过舌状结构弹性复原，使两者恢复到垂直的位置关系。
其中，所述舌状结构的刚性大于瓶体内的液体对舌状结构产生的作用力，保证舌状结构、连杆以及限制件稳定设置在瓶体内。
进一步地，所述连杆的水平横截面呈十字形设计。
进一步地，所述限制件的两端面在瓶体被按压时与瓶体的内壁接触，所述限制件的两端面与凹位吻合。
所述限制件的两端面与凹位吻合，同样有利于按压，起到更加稳定的按压效果。
进一步地，所述限制件呈柱体设计；或所述限制件呈柱体设计，所述柱体的两边分别设有第一接触体和第二接触体。
其中，柱体的顶面为平面，以便于与连杆的舌状结构更好贴合。
其中，以连杆为分界线，分为柱体的左侧和右侧，且柱体的左、右侧中，其中一侧设有顶面，另一侧为顶部敞开设计。顶部敞开设计便于按压连杆，使连杆和限制件收纳于瓶体内。
进一步地，所述限制件呈两端大中间小的空心哑铃型设计。
瓶体呈哑铃型设计，既能起到限制按压形变量的作用，又能缩小限制件的体积，节省材料，又能增加与瓶体凹位的接触面，使挤压变形更加稳定，从而使挤出的液体定量的有益效果。
进一步地，所述限制件的两端面直径相等。
进一步地，所述限制件两端的直径小于瓶体的瓶口内径。
所述限制件的两端面的直径小于瓶体的瓶口内径，便于限制件倾斜放入瓶体内。

其中，以连杆8为分界线，分为限制件7的左侧和右侧，限制件7的左、右侧中，其中一侧设有顶面，另一侧为顶部敞开设计。顶部敞开设计便于按压连杆8，使连杆8和限制件7收纳于瓶体内。限制件7和连杆8整体进入瓶体1后，通过舌状结构810弹性复原，使两者恢复到垂直的位置关系。
实施例 5
如图13和图14所示，本实施例与实施例3的不同之处在于，所述限制件7与连杆8为可拆卸设计。其中，限制件7上设有凹槽，连杆8上设有用于插接到凹槽固定的凸沿，从而使得连杆8固定于限制件7上。
实施例 6
如图15和16所示，本实施例与实施例1的不同之处在于，所述补平部件4呈单U型设计，其包括与瓶体的凹位对应设置的挂耳41和连接挂耳41的连接带42，其挂耳41设计于U型结构的两边，且与瓶体1的凹位2对应，连接带42呈U型结构。
所述补平部件4采用连体式的结构；通过扣合固定于瓶体凹陷位置，再通过标签覆盖瓶体表面进行进一步的固定。
通过设置补平部件4，使瓶体1的外形更美观，且便于用户挤压取用液体。
本实施例中，挂耳41分别可拆卸设置于瓶体1的凹位上。所述瓶体1的侧壁上设有内陷的连接位12，且连接位12的两端分别连接至瓶体1正面和背面的凹位2，所述连接带42可拆卸嵌合设置于连接位12上。
所述凹位2与连接位12在瓶体1上形成的形状与所述挂耳41和连接带42的形状匹配，且所述挂耳41和连接带42一体成型。
其中，所述挂耳41的中心内陷，且内陷的程度小于凹位2内陷的程度。
本实施例中，通过挂耳41的中心凹陷，形成指示瓶体1上按压位置的识别区。通过将挂耳设计为中心凹陷形成所述识别区，这样的设置简单、方便，且可通过模具一体成型设计，节省另外设置识别区的成本。同时，凹陷设计有利于手的稳定握持瓶体。
其中，所述补平部件4的表面还可设置其他一些触摸识别的信息以作为识别区，如小凸点、凹点、纹理或小孔等。通过设置识别区以便于用户更快更准确地找到按压位。
实施例 7
如图17和18所示，本实施例与实施例1的不同之处在于，所述补平部件4呈双U闭环型设计，双U闭环型结构对称设计并有倾斜夹角，双U闭环型的补平部件包括与瓶体的凹位2对应设置的挂耳41和连接挂耳41的连接带42，双U型结构的两端连接，所述挂耳41设在两U型结构的连接处，所述连接带42呈U型设计。所述瓶体1的侧壁上设有用于嵌合连接带的连接位12。
实施例 8
如图19~22所示，一种定量瓶，包括瓶体1和瓶盖（图中未示出），所述瓶体1为按压面呈弧面的扁形瓶体，所述瓶体1的外侧壁上在往瓶体1内腔的方向上设有两个第一凹位112，所述第一凹位112分别设在瓶体1外侧壁正面和背面的中线上，且靠近瓶体1的重心位置，且第一凹位112分别对应于人手握瓶时，手指按压瓶体1侧壁的位置，两第一凹位112之间留有按压间距h，用于限制瓶体1被按压时所发生的形变量，通过按压瓶体1，使两第一凹位112碰触，从而挤出瓶体1内的液体定量；所述第一凹位112内还设有第二凹位3，所述第二凹位3的开口方向朝向瓶体1内腔。
本技术方案通过限制瓶体1被按压时所发生的形变量，从而控制液体的挤出量，使液体的挤出量为定量。本技术方案的定量结构相对于现有的包装容器具有简单、方便，且可控性好，适应于各种按压挤压式定量瓶，更符合消费者的使用习惯的有益效果。
如图2所示，当瓶体1被按压时，向内形变，直到内腔的两个第一凹位112接触，限制瓶体进一步变形，从而获得受控制的变形量，变形时压缩的瓶体空间与液体的挤出量呈正相关。
如图1所示，所述第二凹位3的开口面与第一凹位112的底部相平，所述第一凹位112底部的尺寸小于第一凹位112开口面的尺寸，所述第二凹位3底部的尺寸小于第二凹位3开口面的尺寸，同时还小于第一凹位112开口面的尺寸，且第二凹位3开口面的尺寸小于第一凹位112底部的尺寸，所述第二凹位3开口面边缘与第一凹位112的底部相连，且相连位置形成瓶体1被按压时的受力部位；所述第二凹位3的底部与第一凹位112的开口面相平，且第二凹位3的底部形成瓶体1被按压时的按压位。
这样设置既能扩大了瓶体1的有效容量，又能巧妙利用第二凹位3的底部进行按压，起到限制瓶体1的形变量，和挤出定量液体的有益效果。
其中，所述第二凹位3外壁与第一凹位112内壁之间留有间隙。
其中，所述第一凹位112在瓶体1上的横截面呈梯形或近似梯形的形状，所述第一凹位112的深度由瓶体的形状及其形变对应的空间压缩量决定，为获得明确的按压瓶体的反馈和必要的挤出量，所述第一凹位112的按压间距h大于5mm。
其中，所述第一凹位112、第二凹位3和瓶体1一体成型。这样的结构简单，可以通过模具结构设计为与瓶体1一体成型，以便大规模生产。
本技术方案在使用时的挤压过程需要倾倒瓶身使瓶口朝下，以便液体流出。
显然，本发明的上述实施例仅仅是为清楚地说明本发明技术方案所作的举例，而并非是对本发明的具体实施方式的限定。凡在本发明权利要求书的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明权利要求的保护范围之内。
