Abstract
本发明涉及具有用于保持恒定的预定超压且布置在流体分配容器(50;60)中的压力控制装置(1)的压力控制系统。压力控制装置包括第一圆柱体(15)、在填充有施加所述预定超压的气体的所述第一圆柱体内可移动的活塞(13)、第二室(7),从第二室(7)到装置的外部、通向容器(50;60)的通道、用于释放和关闭所述通道的阀(18,23)。第二室大体为第二圆柱体(2),所述第二圆柱体具有封闭端(34)和设置有边缘部分(4)的开口端,密封部件(5)安装在所述边缘部分上,以封闭第二室,从而第二室围绕第一室,其中所述第一室是密封部件的一部分。
Description
技术领域
本发明涉及根据权利要求1的前序部分所述的用于保持流体分配容器中的恒定的预定超压的压力控制装置。本发明进一步涉及根据权利要求18的前序部分所述的用于制造压力控制装置的方法。
背景技术
具有压力控制装置的容器例如可从PCT专利申请WO-A-99/62791中获知。其中描述的装置用于保持容器中的恒定的预定压力,所述容器布置用于分配流体。所述压力控制装置具有第一室和第二室,以及封闭元件,所述封闭元件相对于第二室可移动,用于根据封闭元件相对于第二室的位置释放和关闭第一室和容器之间的流体连接。第一室填充有气体,所述气体在使用中具有比容器中的压力高的压力。具有预定或参考压力的气体的第二室被封闭,并且位于第一室外面。在根据图2的第一实施例中,第一室设置为杯形保持器,所述杯形保持器颠倒地放在容器中并且具有与器皿或容器的底部和直立壁接合在一起的纵向边缘。在图3中,示出了第二实施例,其中杯形第一室的直径比容器的内径小得多。所述室设置在容器内的中央,并且其纵向边缘与容器底部接合。在图4中,示出了第三实施例,其中与图3中相同的第一室相对于容器偏心地设置。在图5中,盘稍低于容器高度的中间设置,且通过密封环与容器的内壁气密地连接。所述盘将容器分成两个(固定布置的)部分。类似构造在图6a和6b中示出。并且,在图7中,压力控制装置的第一室被设计为柱塞,所述柱塞利用密封环密封到容器的内壁并且在容器内沿轴向可移动。这样,柱塞将容器分成两部分,其中上部分填充有将被分配的流体。从第一室的流体连接终止在下部分。当容器中的压力由于流体已经通过容器顶部上的按钮被分配而降低时,柱塞由于下部分和上部分之间的压差向上移动,直到再次获得下部分和上部分之间的压力平衡。因此,下部分中的压力已经降低,从而第二室中的压力将较高,并且封闭元件将打开第一室和下部分之间的流体连接,从而下部分中的压力将升高。柱塞接着将再次向上移动,直到获得相应于第二室中的预定或参考压力的压力平衡。最终,在根据图8的实施例中,第一室为圆柱形设计,并且具有相应于容器内径的外径,且由此紧配合在容器内。
仅图7中的压力装置在轴向上可移动。在所有其他实例中,压力装置固定地布置在容器内。图7中的整个压力控制装置被设计为柱塞,所述柱塞用作排出流体的可移动活塞。然而,压力控制装置的这种设计由于它的大尺寸是不利的,从而容器的较少部分能够用于分配流体。
作为分离(单独)的模块的上述压力控制装置的另一重要问题是,第一和第二室必须在安装在容器中之前被加压。例如在构造是一体的且生产线以非常高的输出运行的铝制气溶胶罐中,这实际上可能是非常困难的,并且成本高。另一主要缺点是:已经示出,在商业供应链中储存和分配所必须的几个月期间,后来将安装在容器中的分离的压力控制装置中的压力在很大程度上下降。另外,必须利用关闭的流体连接执行压力控制装置的加压,以获得规定量的压力。因此,已知的压力控制装置不适于大工业规模的应用。
发明内容
因此,本发明的一个目的是提供一种具有压力控制装置的容器,其结构和制造工艺更简单,使得可在更大程度上使用容器的体积。本发明的另一目的是提供一种用于容器的压力控制装置,所述压力控制装置容易在装配到容器之后被加压。本发明的这个或其他目的通过如权利要求1所述的压力控制系统和如权利要求18所述的制造方法实现。
本发明的主要优点是能够在液体分配瓶的实现和填充后对压力控制装置加压。由于第二室包围第一室,所以将获得非常紧凑的压力控制装置,从而与已知实施例相比,瓶中的总的可用空间要大得多。由于压力控制装置可被预先制造,并且容易在现有塑料瓶中实现,所以可仅在生产线上进行少许另外的布置就可保持用于例如化妆品的现有生产和填充工序。

具体实施方式
如果没有另外指出,则将在所有附图中一致地使用具体标号,所述具体标号专用于相对于特定附图限定的部件。
在图1和2中,用于保持容器中的恒定的预定超压的压力控制装置1以截面图和透视图示出。压力控制装置1包括具有锥形颈部3和凸缘4的大体圆柱形的容器2,具有阶梯形漏斗部6的环形插入件或封闭元件5安装在所述凸缘4上。在权利要求中指示为“第二圆柱体”的圆柱体2形成压力控制装置1的第二室7。插入件5的外缘部8具有指向下的外环部分9A和指向下的内环部分9B,外环部分9A和内环部分9B包括槽10。插入件5通过超声焊接安装到圆柱体2的凸缘4上。为此,插入件5的槽10的内表面具有锯齿状的或有凹槽的结构,所述锯齿状的或有凹槽的结构在焊接期间用作能量导引器用于非常坚固的密封接合。漏斗部6的下端11被封闭且具有小的中央开口12。具有外密封环或O形环14的杯形活塞13插入杯形圆柱体15中。活塞13和杯形圆柱体15之间的空间(在权利要求书中指示为“第一圆柱体”)限定第一室16。活塞13具有向下突出的杆17,所述杆17具有较宽的圆柱形端部18。中央开口12的直径稍大于圆柱形端部18的直径,从而所述圆柱形端部18能够滑动通过中央开口12。漏斗部6具有向下的圆柱形夹持部分19,所述圆柱形夹持部分19具有用于夹持环形圆柱体21的环形倒钩20。环形圆柱体21的上端22挤压密封环或O形环23。在图1中,圆柱形端部18的上缘24靠着O形环23,这是阀24的关闭位置,阀24由具有杆17和圆柱形端部18活塞23和被挤压的密封环或O形环23形成。
杯形圆柱体15由圆柱形夹持装置26围住,所述圆柱形夹持装置26包括正好围住杯形圆柱体15的圆柱形杯27,并且具有上冠部28,所述上冠部具有凹部30之间的开口29。圆柱形杯27在其上部具有三个通气孔31,其中在图1和2中仅有一个通气孔可见。并且,多个L形小突起或肋(未示出)彼此等距地设置在漏斗部6里面。所述突起或肋设置在漏斗部6的侧面和底侧。因此,在圆柱形杯27和漏斗部6之间存在限定从开口12到插入件5上侧的通道的空间。
圆柱体2朝着其末端逐渐变宽,并且具有较宽端部32,较宽端部32具有向内突出的缘部33,其中容器的端部支靠在所述向内突出的缘部33上(参看图5和6)。圆柱体的底部34具有环形凹陷35,所述环形凹陷在圆柱体2的内侧被加强且具有中央开口36,橡胶制成的所谓Nicholson(尼科尔森)塞子37压入所述中央开口36中。底部34可以已经通过径向支撑肋加强,以抵制升高温度储存条件期间由高压引起的变形。代替Nicholson塞子,也可使用其它类型的密封部件,例如可选类型的橡胶塞、或蘑菇形密封圈或所谓的橡胶绳密封部件、热铆、或使用例如打火机中的球轴承。
图2示出处于打开位置的压力控制装置1的阀25。图3是如图2所示的压力控制装置1的截面图。
在图4中,示出了压力控制阀1的元件的拆分透视图。特别地,可更好地看到具有冠部28的杯27的构造。可进一步看到杆17具有两个槽40和41,这两个槽40和41设置在杆17的相反侧。在槽40和41的构造中,在活塞13的底面沿相反方向设置有两个槽42和43。因此,在阀25的打开位置,其中活塞13在阀25的打开位置平放在漏斗部6的底侧上,存在沿冠部28的开口29上方的漏斗部6的底侧和侧面从打开阀25直到插入件5顶部的通道。
在图5中,压力控制装置1安装在容器50中,所述容器50具有本质上已知的压力阀51和由诸如高密度聚乙烯等适合的热塑料制成的、可在容器50内滑动的柔性活塞52。柔性活塞52形成为或多或少遵循插入件5上部轮廓的杯形圆柱体或圆顶。柔性活塞52另外具有宽的环形圆柱体形密封部件53,所述密封部件53接触容器50的内壁且具有上密封唇53和下密封唇54。上密封唇53设置为具有尖缘的刮除器,从而填充在容器50中的液体将被从容器50的内壁刮掉,因此没有材料或最多仅有非常薄的液体膜留在内壁上。在需要气密密封的地方,也可考虑使用围绕活塞52装配的单独的橡胶O形环。下密封唇54为楔形,并且具有比上密封唇53稍微大的接触面积。如可看到的,容器50形成为圆柱形的瓶。压力控制装置1的圆柱体2到其末端变宽,从而在瓶50的内侧和圆柱体2的外侧之间存在过盈压配合连接。另外,在端部55附近,将瓶50激光焊接到圆柱体2,这提供了非常牢固的气密密封。尽管这里示出环形圆柱瓶50,但是也可将椭圆形或扇形的其他底部用于圆柱形瓶。所述瓶也可为卵形。然后,应相应地调整压力控制装置1的圆柱体2的形状。
工作
上述压力控制装置的功能如下:在第二室7中,填充具有所要求的但优选为约8巴的过压的惰性气体,特别是标准大气。阀24处于其关闭位置(图1)。在第一室16中,填充具有1.5到2.0巴,优选为2.0巴的,恒定预定超压的气体,特别是标准大气。如果容器50中的压力下降到预定压力或超压之下,如果容器50中的液体由阀51分配将发生这种情况,则通道中的压力也下降。这样,第一室16和通道之间不再有压力平衡,且活塞13从阀25的关闭位置(图1)向下移动到打开位置(图2)。由于在圆柱体2的第二室7中存在超压,所以在到容器50的通道上,即在柔性活塞52下面,将存在气流,柔性活塞52将一直向上移动直到第一室16和通道(或容器50)之间再次存在压力平衡。在平衡状态下,阀25再次关闭,且柔性活塞52上方和下方的压力将是相同的。活塞13以往复或振荡方式移动,以打开和关闭阀25,直到达到平衡状态。由于活塞13和杆17重量轻,所以阀25的打开和关闭位置之间的往复运动非常快,从而几乎立即达到平衡状态。
为了以恒定压力或连续的流量从容器完全地分配全部流体,必须在容器中保持超压,直到最后。这仅在下述情况下被提供:如果在最后,随着最后一滴液体被分配,第二室7中的过压至少等于第一室16的预定超压。这意味着应满足一下公式:
P2≥P1*(1+V1/V2)
其中
P1=预定超压
P2=第二室中的初始压力
V1=容器体积
V2=第二室的体积
这意味着体积V2相对于体积V1越小,过压P2就越高。因此,由于圆柱体2的设计在较高压力下更关键,所以对取决于材料性质、制造方法等的圆柱体2的最小尺寸存在实际限制。
在实际实例中,容器的体积V1为150ml,其中将被分配的液体的体积最大为容器体积的90%,即135ml。第二室7的过压P2最初为8.0巴,且工作或预定超压P1为2.0巴。第二室7的体积V2为50ml。
所需要的工作压力P1取决于将被分配的液体的粘度和物理性质。低粘度或中等粘度的凝胶或乳剂(例如,化妆品)所需要的典型工作压力为1.5到2.0巴,在加压配制中后发泡凝胶所需要的典型工作压力为3.0巴,高粘度填料(例如,环氧树脂)所需要的典型工作压力为2.0到2.5巴,湿液体喷射所需要的典型工作压力为3.0巴,精细的液体喷射所需要的典型工作压力为4.0到5.0巴,且干到非常干的液体喷射所需要的典型工作压力超过6.0巴。
在最后的情形下,如果容器的体积V1为150ml,第二室7的体积V2为50ml,则过压P2为24.0巴。因此,压力控制装置1的圆柱体2的构造必须非常稳定,以便经受这样的高过压。必须满足对压力容器的政府规定,这涉及用于圆柱体2的材料的稳定性和选择等。因此,用于制造上述压力控制装置1的工艺也是非常重要的,这将在下面描述。
在图7中,流体分配容器60以截面图示出,其中压力控制装置1以类似于图5和6中的容器50的方式安装。在容器60的上端61,具有按钮致动器63,且包括喷嘴64的传统分配阀62通过卷曲到上端61的圆周环形缘部65安装。阀62的下端67设置有例如聚丙烯或聚乙烯等塑料(塑料材料)制成的中空汲取管68。汲取管68的长度足以使下端69仅接触压力控制装置1的圆柱形杯27(比较图1)。汲取管也可定位在圆柱体的外侧与容器壁的内侧之间。下管端69可被斜着切除,从而防止由于其与圆柱形杯27的表面太过紧密接触造成的阻挡。容器60的工作类似于图5和6的容器50的工作方式。
在一系列实际试验中已经证明,容器50或60中的压力独立于填充速度保持不变,即,在分配流体产品期间,预定超压保持不变,直到全部流体都被分配。
显然,具有柔性活塞52的容器50更适于乳剂或凝胶等具有较高粘度的流体,而具有喷嘴64的容器60更适于空气清新剂、除臭剂、喷漆等低粘度的流体。
制造工艺
压力控制装置1的圆柱体2优选由聚对苯二甲酸乙二醇酯(PET)等注射吹塑而成。用于产生圆柱体2的注射吹塑工艺的主要优点是,能够利用相同的工具或小的改变生产不同的尺寸,且在吹塑工艺期间拉伸的PET材料导致较高的晶体结构,所述晶体结构提供高强度和良好的气障性质。已经证明,具有颈部3、凸缘4、和壁厚度通常为1.5到2.0mm的加宽或更宽的端部32的圆柱体2的结构非常坚固,且最适于包含高的气体压力。
颈部3对于圆柱体2的所有尺寸都保持相同,这允许部件和制造工艺和装配设备的有效标准化。在圆柱体2的底部形成中央开口或孔35。这能够通过钻孔完成,或更有利地,在注射吹塑工艺期间,模制工具的外形在底部具有销,用于成形中央开口或孔35。对于上述激光焊接工艺,在圆柱体的外径上设置锥形区域,以获得与容器或瓶50的最佳过盈压配合。
通过任何适合的合成材料(例如,PET等)的注射吹塑形成插入件5的其它部分,即,漏斗部6,杯形活塞13、环形圆柱体21、和圆柱形夹持装置26。由铝制成的杯形圆柱体15定位在活塞13上方的正确位置且在空气压力下围绕O形环14,且四个向内的凹入部中的三个凹入部形成在圆柱体15的开口端,以防止活塞13脱离。这样,第一室16被保持在预定超压。此后,圆柱形夹持装置26被放在圆柱体15上而圆柱体15和圆柱形杯27之间的空气将通过通气孔31泄漏,并且咬合在漏斗部6的适当位置中。如可在图1和2中看到的,为此,设置了小环槽60,其中冠状凹部30的外环部分61可被咬配合。可选地,杯形圆柱体15也可由PET或任何其它硬合成材料制成。代替凹入部,圆柱体15的外边缘能够通过超声波焊接或一些其它的适合方法装配到适当位置。
容器或瓶50由PET等任何合适的合成材料的适当预制品通过注射拉伸吹塑而成。PET预制品已经具有较小形式的瓶形状。可首先以非常高的输出生产规模分离地(单独地)形成预制品,并且由此是非常经济的。ISBM工艺具有与用于生产圆柱体2的注射吹塑工艺相同的优点,但是另外还具有重要的优点,PET材料是双轴向(即径向和长度方向)拉伸的,这使得根据容器设计,即使具有通常为0.3至0.6mm的薄壁厚度,也能够生产甚至更好的拉伸和气障性质。在拉伸吹塑后,可切掉容器瓶50的端部,以提供容纳活塞52和圆柱体的开口端。
柔性活塞52被装配到瓶50内,且具有开口端部50的瓶50被放在压力控制装置1的圆柱体2上。为了在瓶50和圆柱体2之间获得气密密封,瓶50被激光焊接到圆柱体2。为此,瓶50由PET等透明塑料(塑料材料)制成,且圆柱体2至少利用称为“炭黑”的红外或激光能量吸收材料在离瓶端部53一段小的距离处在环形圆柱体圆周被浸渍。在激光束被向着瓶50的外表面垂直引导期间,具有圆柱体2的瓶50在其纵轴线上被翻转。所使用的半导体激光设备是瑞士Sarnen Leister Process Technologies的波长为820nm的NOVALAS-C系统。所使用激光束的功率为25瓦(连续),旋转速度为3.5转/秒,并且激光束在约10转期间被施加。
尽管已经证明激光焊接产生用于将压力控制装置连接至瓶50的最佳结果,但是也可使用像超声焊接或利用适当的塑料材料粘合剂进行胶粘等其它适当的连接方法。
上述制造方法的主要优点是,可制造压力控制装置,且其第一室可被加压,并且被输送给容器的制造商,且制造商可通过为标准已知工艺的注射拉伸吹塑制造容器,切割容器或瓶底部,通过例如激光焊接将压力控制装置与瓶连接,在压力阀51上填充液体,最终以传统方式通过橡皮塞37对第二圆柱体加压。在用于如在化妆品等中使用的空气溶胶容器的已知产生和装填工艺中容易引入另外的生产步骤,其中例如液体产品通过容器的开口颈部或通过分配阀51被填充。
本发明的另一优点是,由于仅将标准大气或任何其它适合的惰性气体用于压力填充,所以处理工具、设备、和制造环境、及操作流程不需要考虑通常对于危险的易燃推进剂所需要的特定安全要求。
