附图说明
通过阅读下面的说明,参阅附图,本发明将被更好地理解,其中:
图1显示安装在无空气分配器的本发明的一个实施例的通常轴向横截面视图;
图2A和2B显示图1所示本发明实施例的横截面视图,分别为从模具中取出后,及安装上端盖后、组装在分配器之前的视图;
图3显示为上述图所示本发明实施例的一仰视图;
图4A至4E显示分配产品的连续阶段。
具体实施方式
根据本发明所述的装置,如图中所示,是为安装于液体产品的无空气分配器而设计的,并且,特别是化妆或制药产品,图1所示。
该产品被包含于一个贮液器R,在该贮液器底部设置有一个活动基部F,且在顶部具有侧肩E,该侧肩包含一个为产品提供的排放管道C。
该分配器还设置一个动作器,其用于配合活塞(下面将描述)以及恢复弹簧S。
本发明的装置,如图尤其是图2A及2B中所示,包括一个防水的剂量衬套1,其支撑一个阻塞针2。如图2B中所示,该阻塞针2被设计插入一个排放沟12,在本实施例中,其在用于从模具中移出的延伸位置折入并扣合后,如图2A所示,设置于所述衬套1的顶面,该装置在本实施例中作为一个单一部件制造。
为该目的,所述沟12包括可变形的唇缘12a,其在顶部伸出且部分地关闭所述沟。
通过手动推动所述衬套1且挤压弹簧S,针2能在所述沟12内平移,通过一驱动杆3连接至轴向导杆4,在分配产品时,该轴向导杆4能在贮液器R的排放管道C内滑动。
驱动杆3设置一个铰链32,连接该驱动杆至针2,且允许该驱动杆折入。
该驱动杆包括一个凸轮31,其具有一个三角形横截面,在底部,分别结合所述轴向导杆4及所述衬套1,且,在顶部,通过铰链32接合至所述针2的斜边21。因此,该驱动杆3与每一比邻部件有一旋转轴。
轴向导杆4插入以使其在所述管道C内自由滑动,填充所述管道的内部容积,除了其有一个纵向平面部分40(见图3),允许产品穿过所述管道流向所述沟12。所述轴向导杆4还有一侧凸缘41,其配合一个设置在所述管道C内壁的安全钩e。
当所述衬套1安装于贮液器R,所述导杆4穿过所述管道C及所述凸缘41扣合进所述钩e下面的位置。
所述管道C通过一个剂量室10连通所述沟12,该剂量室限制于在所述管道C之上的中心套11内,且同轴延伸至所述轴向导杆4。
所述中心套11设计为以防水的方式覆盖所述管道C,形成一个活塞。
为了提高所述室10的防水性能,形成的活塞为柱面,所述管道C的上边最好设置一个外围唇缘(peripheral lip)p。
所述针2被稳固地侧附置于二弹簧片21a、21b组成的一组弹簧片,在所述针(见图2B)折入之后,其自由端通过止于两槽20a、20b而固定于所述衬套1。所述弹簧片21a、21b在阻塞所述沟12(见图4A及4D)的位置,参与返回、引导、把持所述针的工作。
所述衬套1还包括一个外围罩(peripheral skirt)13,其环绕所述弹簧S,且在底部包括一个肋板13a,在分配步骤的末尾,停靠在所述贮液器R的侧肩E上。
所述肋板13a还配合一个在所述贮液器R内的径向突起提高边(radially projecting raised edge)T,这确保所述衬套1被把持在该贮液器的壳体内,以及所述弹簧S在分配器的防水的关闭位置(见图4E)保持在一定压力下。
本发明的该装置另外包括一个形成动作器的端盖5,其在顶部以一种防水的方式关闭所述沟12。
该端盖为,比如,扣合(如图中可选实施例中所示)或者插在所述衬套1上。
该端盖5包括一个侧喷射孔(lateral ejection orifice)50,连接至一个喷嘴,所述针2的一端部在其以防水方式阻塞所述分配器的位置,停靠在该喷嘴的内圆周。
在需要时,为了提高防水性能,所述孔50的内圆周设置一个角环(angular ring),为所述针2的端部形成一个座。
下面参照图4A至4E,描述该装置的作用过程。
在图4A所示的停止的位置,针2的端部顶对在所述端盖5的孔50上,在所述弹簧片21a、21b以及弹簧S的同步作用下,其处于轻微的压力下,因此,密封地阻塞所述沟12,也就是,密封地阻塞整个分配器。
同时,当所述套11被向上推起,所述轴向导杆4被所述安全钩e向下拉动进入所述管道C,产生旋转力矩至在顺时针方向(见箭头)承受该力矩的驱动杆3,因而增加了针2上的压力。
图4B所示位置对应于产品开始分配阶段的位置,端盖/动作器5在使用者施加的垂直手动压力的作用下相应地开始下降。
贯穿整个阶段,所述导杆4由于在其滑动插入管道C的过程中不可避免的摩擦力的作用而保持不动。
关于所述套11,通过挤压弹簧S以及受驱动杆3逆时针方向的旋转力矩的影响,而开始下降。该下降运动驱动针2向底部及从所述喷射孔50缩回的方向做平移。
同时,剂量室由于套11的活塞作用逐渐排空,通过管道C的唇缘p挤压其壁,导致产品穿过沟12和孔50得到分配。
当压力保持,上述移动继续直至驱动杆3停止在针2的斜边21,如图4B所示。
分配器这时完全打开。
在图4C所示位置,在管道C内的导杆4的夹持状态,由于按压在动作器5上的压力的作用下结束。导杆4开始滑向管道C内部的底部,这时驱动杆保持顶在针2上,因此继续移动,而达到最终获得的剂量,也就是当所述衬套的罩13的肋板13a到达所述贮液器R的凸缘E时,最终获得的剂量(如图4D所示)。
图4E显示返回到图4A所示的停止位置。手动力去除之后导致弹簧S松弛。该松弛最初引起套11及动作器5上升直至针2顶住孔50而停止,导杆4保持在管道C中不动。
驱动杆3顺时针旋转,且推动针2向孔50返回。该运动导致产品被吸入贮液器R,并且逐渐填充所述位于套11内的室10。
然后,在所述管道的导杆4的夹持状态结束,且导杆4向上回升直至其凸缘41停止在对着管道C的所述钩e上,所述针因弹簧片21a、21b的作用保持其向前的位置。
弹簧S而后保持一轻微的压力,因为肋板13a到达一个预定的停止位置,抵靠在所述贮液器R的所述突起提高边T上。
