本发明的第二目的是提供一种具有上述弹性件的液体泵。
为达到上述目的，本发明采用的技术方案是：一种液体泵，包括泵体、能够相对所述泵体的轴向上下运动的头帽，还包括如上述的液体泵用弹性件，所述弹性件设置在所述泵体与所述头帽之间且用于提供所述头帽向上远离所述泵体运动所需作用力。
在一些实施例中，所述液体泵具有与所述头帽固定连接的连接杆，所述泵体上具有沿上下方向延伸的中空状导向柱，所述连接杆能够沿轴向相对滑动地插设于所述导向柱上，所述弹性件沿轴向套设在所述连接杆上或者套设在所述导向柱上。
本发明的第三目的是提供一种具有上述液体泵的化妆品容器。
为达到上述目的，本发明采用的技术方案是：一种化妆品容器，包括容器本体，还包括如上述的液体泵，所述液体泵设置在所述容器本体上。在一些实施例中，所述化妆品容器为真空罐。

实施例1
参见图7至图14所示的一种化妆品容器用液体泵，本实施例的液体泵为乳液泵。该液体泵也称为泵头，其包括泵体2、能够相对泵体2的轴向上下运动的头帽4，以及能够提供头帽4向上远离泵体2运动所需作用力的弹性 件3，其中，头帽4的底部固设有连接杆1，头帽4通过连接杆1能够沿上下方向相对滑动地设置于泵体2上。
参见图1至图5所示为上述液体泵中采用的弹性件3的示意图，该弹性件3整体由塑胶材质制成，弹性件3上形成一供如连接杆1等杆状体沿轴向穿过的中空通道，主要用于弹性件3在液体泵中的安装。弹性件3具有能够沿上下方向弹性伸缩的主体部，该主体部由弹性条31螺旋延伸而成。该弹性条31具有一定的高度与厚度，其完全展开的状态下呈扁带状。参见图6所示，本实施例中，弹性条31沿高度方向的纵向剖面为长方形，如图6-1所示，在其他的实施例中，弹性条31的截面也可以设置为正方形、梭形、菱形、椭圆形、工字型、U字型中的一种，如图6-2所示，还可以是其他未列举的截面形状。
弹性件3整体具有分设于自身轴向相异两端的第一端部3a与第二端部3b，弹性件3的外径自第一端部3a向第二端部3b逐渐增大地设置，亦即第一端部3a的外径小于第二端部3b的外径。本实施例中，弹性条31为一条，其呈螺旋上升的方式延伸，且该弹性条31的一端自下而上、由外至内地螺旋延伸，形成如图1至图5所示的弹性件3，该弹性件3的上端部构成第一端部3a，其下端部构成第二端部3b。
参见图7至图10所示，液体泵处于未被按压状态，弹性件3套设在连接杆1的外侧周部，且弹性件3支撑在头帽4与泵体2之间；参见图11至图14所示，头帽4被向下按压，弹性件3在外力的作用下被按压，第一端部3a与第二端部3b之间的距离减小，弹性件3的整体高度减小。再次松开对头帽4的压持时，在弹性件3的弹力作用下头帽4被向上顶起复位。
弹性件3与液体泵的其他部件均采用聚烯烃类原料制成，使得液体泵整体均由塑胶材质制成，该液体泵也称为全塑泵，其可以整体地被回收，而不需要将弹性件3单独地予以分拣回收。
实施例2
参见图15至图22所示，本实施例与实施例1的区别主要在于，本实施例的液体泵中，弹性件3的第一端部3a在下且第二端部3b在上。该弹性件3同样套设在连接杆1上且同样能够提供头帽4向上远离泵体2所需的弹性作用力。
实施例3
参见图23至图26所示，本实施例相比实施例2的区别主要在于，本实施例中，弹性件3还包括位于第一端部3a的第一连接环32，及位于第二端部3b的第二连接环33，弹性条31此处仍为一条，该弹性条31的一端部与第一连接环32相接，弹性条31的另一端部与第二连接环33相接。实际制造时，该弹性条31与第一连接环32、第二连接环33优选采用注塑的方式注塑而呈一体。其中，第一连接环32与第二连接环33均为沿周向呈封闭状的环体，第一连接环32的外径小于第二连接环33的内径。
参见图27、图28所示，弹性件3套设在连接杆1的外侧周部，其两端分别抵靠在头帽4与泵体2之间，从而稳定地提供头帽4向上远离泵体2所需的弹性作用力。
实施例4
参见图29至图32所示，本实施例示出了液体泵中弹性件3的另一种结构形式，具体为，在实施例3中弹性件3的基础上，本实施例的弹性件3中弹性条31有两条，且这两条弹性条31的螺旋旋向相同，每条弹性条31的两端分别接合在第一连接环32与第二连接环33上。
实施例5
参见图33至图38所示，本实施例示出了液体泵中弹性件3的另一种结构形式，具体为，在实施例4中弹性件3的基础上，本实施例的弹性件3中弹性条31有三条，三条弹性条31的螺旋旋向均相同。三条弹性条31沿第一连接环32、第二连接环33的周向依次分布，且每条弹性条31的两端分别接合在第一连接环32与第二连接环33上。
实施例6
参见图39、图40所示，本实施例中示出了一种化妆品容器，其具体为真空罐。该化妆品容器包括用于盛装化妆品的容器本体6，以及可拆卸地与容器本体6配合的容器盖5，此处的液体泵具体为真空泵，该真空泵固定设置在容器本体6上。其中，泵体2上具有沿上下方向延伸的中空状导向柱21，连接杆1能够沿轴向相对滑动地插设在导向柱21上，弹性件3套设在该导向柱21的外侧周部上，并提供头帽4向上远离泵体2所需的作用力。本实施例 中采用的弹性件3的结构与实施例1中的弹性件3的结构相同，且第一端部3a在上、第二端部3b在下。
实施例7
参见图41、图42所示，本实施例与实施例6的主要区别在于，本实施例中，弹性件3的第一端部3a在下、第二端部3b在上；且弹性件3套设在连接杆1上并位于导向柱21的上方。
综上所述，在利用液体泵进行泵压式挤出化妆品的化妆品包装容器中，采用本发明的上述新型液体泵，其中的弹性件3的结构能够在保证提供液体泵中头帽4以足够的弹性回复力的基础上采用全塑材料制成，如此，液体泵整体能够被回收，而不需要专门地将弹簧拆卸分离后再予以回收，回收方便且回收成本降低，也使得液体泵的材料能够被充分地回收利用，避免了环境污染及资源的浪费。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围之内。
