用于分配的包装本申请是中国专利申请03101921.8(申请日:1996年7月23日;分案提交日:2003年1月23日;发明名称:用于分配的包装)的分案申请. 技术领域本发明涉及产品的包装,特别是涉及一种用于液态产品的自密封阀及其类似物。 For dispensing package of the present application is a China Patent Application 03101921.8 (filing date: July 23, 1996; divisional filing date: January 23, 2003; Title: for dispensing packaging) of a divisional application technology. The present invention relates to product packaging, in particular, it relates to a liquid product of a self-sealing valve and the like. 背景技术现在有很多不同类型的用于包装非固态产品的包装或容器,这类产品能够流动,诸如液体或流态化的材料,包括液体、糊状物、粉末及其类似物,这些物质在此处被笼统地总称为液体。 BACKGROUND ART There are many different types of packaging for packaging non-solid products or containers, such products can flow, such as a liquid or fluidized materials, including liquids, pastes, powders and the like, these substances here it is generally referred to as liquid. 有些这种包装包括一分配器,它可使选定量的液体从包装中排出,然后再密封,以关间包装。 Some such packages include a dispenser which allows a selected amount of liquid from the package, and then sealed to close the packing room. 自密封的分配阀已经用在用于某些类型的产品的包装中,诸如在授予Drobish等人美国专利No.4,728,006中所公开的容器,它是为香波、 润发剂及其类似物设计的。 Self-sealing dispensing valve has been used in certain types of product packaging, such as containers grant Drobish et al U.S. Patent No.4,728,006 disclosed, it is for the shampoo, conditioner agents and analog design. 但是,已经知道这种阀存在某些密封问题和分配不稳定的特性,特别是在包装受到较大的温度变化时。 However, it is known the existence of such a valve sealing problems and unstable distribution of certain characteristics, in particular by large temperature changes in packaging. 用多数普通的塑料构造的阀至少在某些类型的包装中不能使用,这是因为,它们会与产品M应或降低产品的品质。 Most common plastic valve structure at least not be used in certain types of packaging, this is because they will be the product M or lower the quality of the product. 例如,在食品包装中,必须小心地避免使用可能含有任何类型的毒素的阀材料。 For example, in food packaging, care must be taken to avoid the use of any type of toxin that may contain a valve material. 此外,产品中的活性成份可使阀变脆或变软,从而损及阀的设计流量和/或阀的自密封特性。 In addition, the active ingredient in the product valve can become brittle or soft, to the detriment self-sealing characteristics of the design flow and valve and / or valve. 近年来已经将液态硅橡粘合剂阀用于某些类型的包装中,并已经被证明是特别有利的,这是因为该材料固有相当大的惰性,因而不会降低产品品质或与产品起反应。 In recent years it has been the liquid silicone rubber adhesive valve for some types of packaging, and has proven to be particularly advantageous, since the material is fairly large inherent inertia, and thus will not play with the product or reduced product quality reaction. 这类包装的例子已在授予Brown的美国专利No.5,033,655中提出。 Examples of this type of packaging has been proposed in U.S. Patent No.5,033,655 granted Brown's. 虽然液态硅橡粘合剂具有许多可在包装中使用的属性,但它也有其它一些使这种应用产生问题的特性。 Although liquid silicone rubber adhesives have properties that can be used in packaging, but it also has some other problems to make this application features. 例如,液态硅橡粘合剂零件的表面非常粘,有非常大的摩擦系数。 For example, the surface of the liquid silicone rubber parts are very sticky adhesive, there is a very large coefficient of friction. 因此,在企图用传统的带螺紋的阀环结构将分配阀装在容器上时,在阀环被可靠地上紧,足以形成防漏的密封以前,阀法兰的表面将牢牢地粘附在容器和阀环的相邻表面上.上紧阀环经常会使阀的法兰以及整个阀变形,失去其原设计形状,从而妨碍形成可靠的密封,和/或改变阀的预期的分配和密封特性。 Thus, in attempting to use conventional threaded valve ring structure in the dispensing valve mounted on the container, the valve ring is tight and reliable ground, sufficient to form a leak-proof seal before the surface of the valve flange will firmly adhered adjacent surfaces of the container and a valve ring flange and tighten the entire valve valve ring deformation often causes valve design loses its original shape, thereby preventing the formation of a reliable seal, and / or changes in the expected distribution of valves and seals characteristics. 与在用于产品包装的分配阀中使用液态硅橡粘合刑有关的另一缺点为,现在还没有一种能以一种如下所述的方式将阀连接到容器上的粘合剂,即使之可以承受阀和容器反复承受的工作压力,液态硅橡粘合剂阀表面的独特的无孔特性使一般的粘合剂的使用成为不可能。 With the use of liquid silicone rubber adhesive dispensing valve for punishment in product packaging Another drawback associated to, there is no one capable of in a manner described below to connect the valve to the adhesive container, even if The valve and the container can withstand repeated job stress, the unique characteristics of the non-porous adhesive liquid silicone rubber valve surface make use of general adhesives impossible. 因此,要着重考虑将液态珪橡黏合剂阀以这样一种方式M容器上,使之不会泄漏, 同时能承受分配包装的反复加压和减压。 Therefore, an important consideration will Gui rubber adhesive liquid valve in such a way that M on the vessel so that it does not leak, and can withstand repeated pressurization and depressurization of the dispensing package. 原有的分配包装所遇到的另一问題涉及在包^器、阀与液态产品之间得到一恰当的设计平衡,以使产品可以不断地分配而不需要过大的力,同时能恰好只排出使用者所要求的产品量,特别是与所涉及的产品类型保持一致。 Another problem encountered by the original distribution package involves between package ^, valves and liquid products have a proper design balance, so that the product can continue to distribute without the need for excessive force, while only just the amount of product discharge requested by the user, especially consistent with the type of product involved. 例如在分配高浓度的液态产品诸如液体洗手皂及其类似物时,使用者在每次使用时通常只需要少量的或数滴皂液,以得到满意的结果。 For example, in a high concentration of liquid product dispensing liquid hand soap, and the like, the user each time you use usually requires only a small amount, such as a few drops of liquid soap or to obtain satisfactory results. 与^目反,当使用其它类型的液态产品诸如毛皮湿润剂、鞣皮剂及其类似物时,使用者每次通常都需要大量的产品.同阀在已释放掉压力时迅速且可靠地关闭的能力一样,阀响应作用在容器上的中等压力而迅速并且容易地打开的能力也是重要的.重要的还有必须保持作用在容器上以便在阀被打开时维持流体通过阀的压力的值,在设计分配的包装时,非常希望有在所有这些因素之间迅速而准确地得到恰当的平衡的能力。 And ^ Head contrast, when using other types of liquid products, such as fur as wetting agents, when Tanning and the like, each time a user usually requires a lot of products quickly and reliably with the valve closes when the pressure has been relieved Like capacity, acting on the valve in response to the pressure medium container and the ability to easily and quickly opened is also important. There must be an important role to maintain the pressure of the fluid through the valve when the value of the valve on the container is opened, In the allocation of packaging design, highly desirable to have the ability to quickly and accurately obtain the right balance between all these factors. 发明概述根据本发明的一个方面,提供了一种用于液态产品包装的分配阀, 它属于这样一种类型,即具有一容器,此容器中有一排放口,该分配阀包括: 一围绕容器的排放口密封的边缘部分、 一头部和一通常是J形的连接套筒;所述头部包括一具有一小孔的中心区,该小孔响应在容器中的预定排放压力而打开,以允许液流经过,并在去掉预定的排放压力时关闭,以切断经过的液流;所述连接套筒具有可弹性变形的结构,它具有一与上述边缘部分连接的第一腿部和与上述头部连接的第二腿部;上述第一和第二腿部以一为锐角的夹角互相取向并在一弧形部分处彼此连辨,该孤形部分在从容器中分配产品时有利于上迷头部的运动,根据本发明的另一个方面,提供了一种用于液态产品的分配包装,包括: 一容器,将其形状作成能在其中保存一种所逸幹的液态产品,并有一排放口,和一分配阀,用于控制液态产品从上迷容器的流动,它具有一边缘部分、 一头部和一可弹性变型的连接套筒;所述边缘部分围绕上述容器的排放口密封,所述头部包括一具有一小孔的中心区,该小孔响应在容器中的预定排放压力而打开,以允许液流经过,并在去掉预定的排放压力时关闭,以切断经过的液流;所述连接套筒具有一与上述边缘部分连接的第一端部和与上述头部连接的第二端部;上述'第二端部具有倒J形,它成弧形fel伸至上述头部,以在4器中分配产品时有利于上述头部的运动.#>据本发明的另一方面,提供了一种用于液态产品的分配包装,包括: 一容器,将其形状作成能在其中M—种所选择的液态产品,并有一排放口,和一分配阀,用于控制液态产品从上述容器的流动,它具有一边缘部分和一头部;所述边緣部分围绕上述容器的排放口密封,所述头部包括一具有一小孔的中心区,该小孔响应在容器中的预定排放压力而打开,以允许液流经过,并在去掉预定的排放压力时关闭,以切断经过的液流;上述头部有一与周围环境连系的外表面和一与容器中的液态产品邻接的内表面,头部的外表面从上i^器外面看去时通常具有下凹的形状,所述内表面有一中心区和一通常倾斜的朝中心区向内倾斜的外部,以使外表面和内表面朝头部的中心区域会聚,从而提供具有邻接小孔的厚度减薄的带^JL结构,根据本发明的另一方面,提供了一种用于液态产品包装的分配阀, 它是这样一种类型,即具有一容器,该容器中有一排放口,该分配阀包括: 一围绕上述容器的排放口密封的边缘部分和一头部,该头部包括一具有一小孔的中心区,该小孔响应在上it^器中的预定排放压力而打开, 以允许液流经过,并且在去掉预定的排放压力时关闭,以切断经过的液流;上述头部有一外表面和一内表面,所述外表面与周围环境接触并且当从容器外面看去时具有通常下凹的形状,所述内表面与上述容器中的液态产品接触并具有一中心区和一通常倾斜的、朝上述中心区向内倾斜的外部,这样上述外表面和内表面朝上述头部的中心区会聚,以提供一具有邻接上迷小孔的减薄的厚度的带坡度结构,根据本发明的另一方面,提供了一种用于液态产品包装的分配阀, 它属于这样一种类型,即具有一容器,此容器中有一排放口,该分配阀包括: 一边缘部分、 一头部和一可弹性变形的连接套筒;所迷边缘部分围绕上述容器的排放口密封;上述头部包括一具有一小孔的中心区,该小孔响应在上i^:器中的预定排放压力而打开,以允许液体流经,并在去掉预定的排放压力时关闭,以切断经过的液流;所述连接套筒有一与上述边缘部分连接的笫一端部和一与上述头部连接的第二端部;连接套筒的上述第二端部具有倒J形,它成弧形地延伸至上述头部中,以在从上述容器分配产品时利于上述头部的运动.4fl据本发明的另一方面,提供了一种用于液态产品包装的分配阀, 它是这样一种类型,即具有一容器,该容器中有一排放口,该分配阀包括: 一阀边缘部分, 一阀头部和一连接套筒部分;所述阀边缘部分的形状可围绕上述容器的排放口而密封;所述阀头部包括一'J、孔,该小孔打开和关闭以便控制流体流动,其形状是这样,即,基本上在中心处沿轴向相对于所述阀边缘部分而移动,所述连接套筒部分有一与上述阀边缘部分连接的边缘端部区域、 一与上述阀头部连接的相对的端部区域和一可弹性变形的结构,该结构沿轴向伸展,以向所迷阀头部施加沿径向向内的作用力,这有助于在分配之前在所述阀头沿轴向移动时可靠地使所述小孔完全关闭。 SUMMARY OF THE INVENTION In accordance with one aspect of the present invention, there is provided a dispensing valve for a liquid product packaging, it belongs to a type, i.e., having a container, this container having a discharge opening, the dispensing valve comprising: a surrounding container discharge port sealing edge portion, a head portion and a generally J-shaped connector sleeve;

It should be understood larvae L 6 may only Burgundy data distribution characteristics required to take many different shapes, feet and / or structure. For example, the holes 6 may include single crack, especially in smaller streams require less or when. larvae L 6 may also include three or more crack, especially in larger or coarser required flow and / or liquid products containing such某些类型的色拉调料等团粒时。也可以把其它形状的孔6,例如洞、鸭嘴形等与阀3配合。自密封分配阀3最好专门地构形成与特殊的容器2和特定类型的液态产品配^H吏用,以便得到所要求的精确分配特性。例如,液态产品的粘度和密度在设计阀3的特殊结构时,同容器2的形状、尺寸和强度一样,都是重要的因素,特别是在将分配包装1造成用于底部分配时。在获得理想的分配特性时,阀材料的刚度和硬度,以及阀头5和连接套筒7 的尺寸和形状也都是重要的,而且应当同时与容器2和被从其中分配的液态材料18伃细地匹配,本发朋的一个在使用的实施例是专门为从其中分配液态家用产品, 诸如洗碗机用清洁剂、液体肥皂、润肤乳、食品及其类似物而设计的。 当要从一具有位于其底部4的阀3的用于底部分配的聚丙烯吹塑容器中分配这类液态产品材料时,发现一种专用的阀3特别适用,该阀的具体结构如下。阀的边緣法兰4的外径和内径分别为17.78mm和14.74mm, 而阀头5的边缘42的外径为11.15mm,中心部分41的外径约为5.62mm. 连接套筲7的厚度约为0.33mm,并具有从边缘法兰4的底部32测至阀头5的缘52而得到的总高度2.944mm.阀头外表面38的半径为7.37mm, 而内表面39的边缘部分40的半径为0.89mm。因此,阀头5在边缘42 处的总厚度约为0.198mm,在中心部分41中间的总厚度约为化89mm。在从边缘法兰4的底部32测至中心部分41的顶部时,阀3的总高度约为6.10mm。缝55和56的长度约为5.59111111,并在阀的中心部分41按正方形对中。阀用由道科宁(Dow Corning)公司生产的商标为"SILASTIC LSR"的液态珪橡粘合剂整体地模制而成,在具有上述的特殊尺寸和特性的阀上进行的实mt明,当阀受到容器2内的等于大约635mm - 711.2mm水柱的压力时,阀3就M打开。使阀3迅速打开的压力在此处一般称为预定的打开压力或分配压力。当容器2的内部压力降到低于大约406.4nun-457.2mm水柱的压力时,阀将自动地迅速关闭.使阀3迅速关闭的压力在此处一般称为预定的关闭压力。当所说的阀3打开时,通过孔6排出基本上恒定的液态产品流, 即使有额外的压力作用在容器2上。可以理解,按照本发明,阀3可以采用很多不同的形状与尺寸,特别是在与容器2的类型和祐:从容器中分配出的液态产品相配时,阀3的的范围内变化。也可以对被分配的液态产品的流动特性作相当大的调节, 诸如对于比较宽的枉状流、细的针状流、 一小团,等等。在工作时,分配包装l以如下所述的方式起作用.阀3通常弟^取闺7所示的向内突出的取向,其中阀3基本上保持其原有的模制形状,没有变形,连接套筒7完全缩回,排放口6完全关闭,当如同闺示的底部分配包装l所示的那样,将阀3装在容器2的底部上时,阀3的结构要^吏得即使在容器2完全装满时由液态产品18作用在其上的液压头的压力作用下,排放孔6也将保持可靠地关闭。当使附加压力与容器2的内部联系,例如用手向内弯曲容器侧壁14 和15时,连接套筒7起一滚动隔膜的作用,并允许阀头5通过折起连接套筒7开始沿轴向向外的方向朝分配包装1的外部偏移,然后套筒也开始以滚动的方式如困8所示地向外伸出.连接套筒7的向外突出的J形结构有助于起动连接套筒7的这种滚动.连接套筒7从其初始的模制形状(图7)开始的弹性变形在阀3中产生一复杂的应力方式,该应力又将套筒弹性地推回其初始的或正常的形状,这种力包括一由连接套筒7作用在邻近边缘42的阀头5上的向外的转矩,该转矩将如同在下文中更加详细地说明的那样会弹性地将排放孔6推向其打开位置。如图9所示,当使附加压力与容器2的内部联系时,阀头5继续通过将连接套筒7在其自身上滚压过而继续沿轴向向外移动.阀头5的边缘42通过阀的边缘法兰4的中心。当使附加压力与容器2的内部联系时,阀头5继续朝分配包装1的外部向外伸出,直至如图10所示连接套筒7 4^P伸出。当阀头处于完全伸出的位置(图IO)时,在连接套筒7中建立起来的应力使连接套筒7的侧壁部分45采取一与阀头S的边缘42同心并在其周围的大体的圆柱形形状。连接套筒7的侧壁45从其初始的模制形状往后折叠180度,成为一与阀头5的边缘42平行的取向,并形成一外唇或外沿65,当使附加压力与容器2的内部联系时,如图ll所示,阀头5继续向外移动。但是,由于连接套筒7完4K申出,阀头5进一步的朝外移动沿纵向拉紧或拉伸连接套筒7,从而加大了作用在阀头5上的朝外的转矩。另外,阀头5的进一步的朝外移动会特別地沿其外表面38拉平或拉直阀头5,这可在图11中最清楚地看出,这一拉平运动会扩大或扩张阀头5的圃形平面构形,这种扩大又受到通过连接套筒7作用在阀头5的边緣42上的沿径向向内的力的抵抗,从而在阀3内产生另一种复杂的应力方式,该力包括力囝沿径向向内的方向压缩阀头5的力,由于阀头5的倾斜形状,认为压缩变形的主要部分是在阀头5的中心部分41附近发生的,通过比较图11中所提供的虚线困形与实线困形可以更清楚地看出,当连接套筒7如虚线所示处于全部伸出的位置,使附加压力与阀3的内侧39 联系时,外沿65如图11的实线所示沿轴向向外并沿径向向外移动。由于通过连接套筒7而作用于其上的转矩力,阀头5的边缘42如困所示的向内弯曲或弹性变形,如困12所示,当使附加压力与容器2的内部联系时,阀头5通iti^ M筒7的进一步的纵向拉伸和阀头5的平面形状的进一步扩大而继续向外移动.这一运动可通过比较闺12中41供的虚线困形和实线困形而更清楚地看出.外沿65从困ll所示的与图12的虚线图形相对应的状态以沿轴向向外和沿径向向外的方式移动至困12中用实线表示的位置。由于通过连接套筒7而作用于其上的加大的转矩力,阀头5的边缘42在图中更加向内弯曲或向内弹性变形。如困12所示,这些组合的力和运动还用于进一步地将阀头5压成分叉的状态,其中,作用在阀头5上的组合力将在有任何附加的向外力作用在阀3的内侧39上时使其由于^il运动而快速地向外打开,将阀瓣57以困13和14中所示的方式分开,从而经过排放孔6分配液态产品。作为此处所用的术语,即阀3的分叉状态示于图12中并限定了一个比较不稳定的状态,这个状态是阀3恰好在打开至图13和14所示的全开状态之前所采取的状态.当阀3经过图12所示的分叉状态时,作用在阀头5上的组合力在给定的瞬间处于一种非常暂时的不稳定的平衡状态,然后迅速地将阀头5变成一大体是凸出的形状, 同时将孔6打开。在由图12中的实线示出的分叉状态,阀头5采取一近似为平面的盘子的形状,其外表面38在沿65和阀瓣缘60之间向内成杯形,而内表面39则朝孔6的中心略向外弯曲。阀3的迅遴打开至少可以部分地通过由连接套筒7作用在阀头5上的转矩实现,如图12中所示的例子所指出的那样,该转矩足以明显地改变阀头5的边缘42的形状,当阀3采取困13和14所示的完全伸出和完全打开的位置时,阀瓣57以及与之有关联的阀头5的边緣部分61向外弯曲或弹性变形,从而仗阀头5的沿65变小或^收缩。阀瓣57力图沿在端部55a和55b或孔缝55和56之间延伸的线张开地折叠。除去由连接套筒7作用在其上的取向朝外的转矩以外,由连接套筒7作用在阀头5上的沿径向向内的持续压缩力协力将排放孔6保持在全开的位置, 即^t与容器2的内部联系的压力下降.因此,在排放孔6通it^fe加预定的打开压力而被打开以后,为保持液流经过孔6所需的压力降低或低于临界压力,以致能更易于分配和流动控制.由于连接套筒7的弹性用于抵抗阀头5的张大作用,并因而能压缩阀头,以得到一iS^打开/iSi4关闭动作,如果稍微改变连接套筒7的弹性,诸如将连接套筒7做得厚一些或薄一些,那么,对于任何一种特殊的应用可由此而调整迅速动作的程度的大小。同样,也可以调节环61的弹性强度以实现所要求的迅速动作。通itt接套筒7作用在阀头5上的组合的压力和转矩力将阀瓣57打开至一般为预定的形状,以使经过排放孔6的流量保持基本恒定,即使在容器2上作用有相当大的压力差.如困13和14中所清楚地表示的那样,在阀3沿打开方向经过图12所示的分叉状态之后,它iSd泉而确定地采取图13和14所示的全开状态,其中,阀瓣57的端缘60沿径向向外分开,以使排放孔6采取一星形的平面构形,这在图14中可最清楚地看出。阀头5的边缘42在液态产品18的压力和由连接套筒7作用在其上的弹性转矩的作用下稍微向内转动或摆动,所述转矩继续弹性地将阀3 朝其原来的模制形状(图7)推回.连接套筒7在由容器2中的压力和液态产品经过孔6的动力流产生的向外的力的作用下在轴向和周向上都保持受拉力。所示的阀3的几何尺寸,特别是阀头5和连接套筒7的形状都用于迫使阀3成为图13和14所示的形状,只要孔6迅速打开。当容器2内的压力降低时,排放孔6仍然保持打开,处于如图13和14所示的基本上全开的位置,直至压力达到预先选定的关闭压力,此时, 在连接套筒7中通过其从原来的模制形状(图7)的弹性变形而产生的力将阀头5向内拉回,经过分又状态而处于闺IO所示的凹形取向,从而用一网头5的迅迷关间动作用于非常迅迷和非常完全地关闭孔6,从而准确地切断从包装1中被分配的液态产品流并且无任何的点滴,即使在分配非常粕和/或非常稠的产品时,阀3将继续采取图10所示的全闭和全伸出位置,直至容器中的内部压力进一步降低,从而允许连接套筒7的弹性将阀头往回移至图7所示的完全缩回的初始位置。至少某些由本发明所设想的阀3有比较高的预定关闭压力,诸如其性质为431.8mm - 457.2mm水柱的压力,这样孔6即使在容器2未具备任何回吸的压力或负压时也能可靠Abi2^关闭,此外,至少某些这类阀3 的连接套筒7被构造成能提供足够的弹性,以自动地将阀头5移回至全部缩回的位置(图7),而且不需要来自容器2的^T回吸的压力或负压。因此,阀3可以容易地适合于与包括可压扁的袋、管及其类似物的容器配合使用。还有,阀3特别适合于诸如困1-3所示的底部分配包装,在此,阀3通常支承一液态产品柱,在分配包装1的许多实施例中,容器2被设计成具有刚性较大的侧壁14和15,它们在被挤压后恢复其原有的形状。在这类实施例中,通常都希望在从容器2中分配液态产品之后将空气吸回至容器2中,以防止容器2被压扁,从而有利于继续容易地进行分配,直至容器2完全变空为止。当阀3处于完全关闭和完全缩回的位置(困9)时,阀头5的凹形结构使孔6易于向内打开,以致空气能被吸回至容器2中,但是又能确实地防止孔6以能允许泄漏的方式向外打开。因此,即使薄壁容器2比较薄弱也可以使用阀3而不致明显大地压扁容器侧壁14和15,参看图15,分配包装l可以设有一强制关闭的结构,以在分配包装1在被运输或类似情况下例如在最初的装运、旅行等时防止意外地排放。图15所示的分配包装1包括一滑动挡板70,它在关闭时实际上阻挡了连接套筒7和相联的阀头5的向外滚动伸出。通过限制连接套筒7的向外伸出运动,就防止了阀头5转换成下凹的形状,从而保持排放孔6完全关闭。当挡板70向側面滑出,离开在下面的阀3时,阀3就自由往复并打开孔6,以从容器2中分配液态产品。图16是分配包装1的另一种封闭结构的局部示意困,其中,设有一可取下的盖71,以通过传统的紧闺装置,诸如按锁、铰链等(未示出)与固定环23可拆卸的连接,所示的盖子71有一大体是扁平的外表面72, 一内表面73和一SJ柱形側壁74,側壁的尺寸和形状^t^^^的内表面73在阀头处于其完4^申出的位置时靠在阀3的沿65上.盖的内表面73 的中心部分包括一向内突出的突起部分75,它在所示的例子中大体上呈凸出的半球形的节,该节朝阀3向内伸出至一与阀3的杯状外表面38相邻的位置,将节75的形状做成可强制地将阀头5保持成下凹的构形,从而可靠地保持孔6完全关闭.阀头5在滚动的连接套筒7上的往复运动使分配包装1具有若干重要的优点,例如,最好将连接套筒7构形成具有足够的弹性,这样在容器2内产生的诸如那些由热膨胀或类似情况而引起的不正常的压力增大可由间头5相对于连接套筒7的轴向移动抵消,以致能减轻作用在排放孔6上的额外压力,这样,如果分配包装1在使用时与液体肥皂或香波配M用,而后者在沐浴室或者带浴池的室中用于按倒置的状态悬挂, 则当淋浴室中的环境温度上升,而不是使有关的压力增加直接与排放孔6 连系,以致可能4吏4^放孔无意地打开时,阀头5沿轴向向外移动,释放任何这种压力,从而防止液态产品由于任何意外而从分配包装l中泄漏。另一通过连接套筒7的滚动隔膜动作和阀头5的轴向往复运动得到的益处的例子为连接套筒7最好被构造成具有足够的弹性,以使阀法兰4 的任何不对准和/或变形,例如在将阀装到容器2上时所遇到的,不会传到阀头5上,从而使排放孔6能不受妨碍地工作。如上所述,由于液态硅橡粘合剂固有的粘稠性质,将用硅橡粘合刑制成的阀M容器2上会十分困难,并且常常产生阀3的边缘法兰4的某种不均匀的压缩和/或变形。没有连接套筒7的滚动隔膜动作,任何一种这类变形都直接传给阀头5,它又扭曲排放孔6并改变诸如其预定的打开压力、关闭压力、流量等重要的设计特性。与本阀3相关联的滚动隔膜连接套筒7试图使阀头5 与边缘法兰4隔开或脱离,以使其能自由浮动,从而避免这类问题。通过本发明的这一方面得到的益处的再一例子是连接套筒7最好被构形成具有足够的弹性,以使作用在容器2上的振动、冲击力及类似物通过网头5在浪动的连接套筒7上的移动而被吸收和/或得到後沖,以致能a排放口6的意外打开,在分配包装1掉在地上,有力地撞击在一工作表面上或是要不然受到i^振动或摇动的情况下,由容器2中液态产品的加速和/或减速产生的冲击力将用不同的方法与排放孔6直接连系,并力图使其意外地打开.不过,阀3的连接套筒7的滚动作用对这种撞击力起着緩冲垫或减震器的作用,从而大大地减少了液态产品从分配包装l中意外地排出的机会.在相似的情况下,当分配包装l用于在使用前通常都要晃动的非均质液体诸如某些色拉调料或类似物时,连接套筒7有助于吸收这种振动,从而防止泄漏,通过本发明的这一方面得到的益处的又一例子为连接套筒7最好被构造成具有足够的弹性,以使只需要用非常緩和的、基本上低于阀3的预定打开压力的压力将阀头5从其完全缩回的位置(困7)移至4^P伸出的位置(图7),从而提高包装l的分配"感".当使用者握住容器2时即使在侧壁14和15上有非常轻的挤压,也会滚动地使连接套筒7和阀头5 伸出至图10所示的完^f申出和完全关闭的位置,此时,阀头5瞬时停止, 液态产品的进一步移动受到阻止,直至在容器2上作用附加力,使容器2 内产生一大于阀3的预定打开压力的内压.连M筒7和阀头5的这个运动由使用者通过接触或感觉感觉到,其形式通常是当阀头5到达完全伸出的位置(图IO)时在容器侧壁14和15上作用有振动或波动。这种波动给使用者发出信号,表明阀头5已经4^P伸出。进一步加压将使阀3 i^逸打开并分配液态产品,当阀3 iS^打开和i5ti4关闭时,类似的振动或波动经过容器侧壁14和15传给使用者,以协助得到精确的流动控制。在所示的分配包装1的例子中,阀3以一种如下所述的方式安M 容器2中,即,使阀头5在图7所示的完全缩回的位置与图13和14所示的完4^申出的排放位置之间变动,在图7所示的位置,阀3整个位于容器2的内部,以便完全地贮放阀3,而在图13和14所示的位置,阀头5和相联的孔6整个位于容器2的外部,以便通过它们精细地分配液态产品。通过使阀头5在这两个极端位置之间变动,阀3可在不使用时通常保持不外露并固定在容器2内,但在分配时又不致牺牲洁净性。另外, 阀3最好隹于容器2中,以致连接套筒7的沐形部分51设置在吝器支座13的底部25附近,这样如果分配包装往下撞击在一表面上,阀3与表面之间的支撑点将防止阀3变换至完dH申出的位置,并由此保持孔6关闭, 防止意外的泄漏。分配包装1具有相当多的用途,它能够容易而精细地分配非常不同的液态产品,自密封阀3与容器2和从其中分配出的液态产品18的种类都匹配,以便能迅速而可靠地密封,但是在^L使用者,时又易于打开, 不需要额外的压力或作用力.其构形为折起的并且能滚动地延伸的可以弹性变形的连接套筒7能适应容器2中的热膨胀,吸收作用在容器上的冲击力,能适应在将阀法兰安装到容器上时可能作用在阀法兰上的任何不对准和/或变形,并提供一种能大大地方便准确分配的独特的分配感. 阀3要构成当孔6迅速打开时能建立一从其经过的大体恒定的流量,即使在容器2受到范围相当宽的压力时。阀3还最好被构造成一旦排放孔6 打开,为保持液体流所需要的压力值就变小,从而能更容易地操作和控制,而不必牺牲可靠的密封.分配包装1特别适于底部分配结构、摇动式容器以及其它类似的包装概念,而且不会有泄漏.参考标号la(困20-23)总的代表体现本发明的另一分配包装,它特别适于^M目关联的容器2a的顶部分配产品.由于分配包装la与前面描述的分配包装1相似,因此在图1 - 16和图17 - 23中出现的相似部分分别用相同的对应参考标号来表示,只是在后者的标号中有尾标"a"。所示的容器2a(图20)是专门为顶部分配而设计的,它包括--般为弹性的长椭圓形容器体,该容器体可用合适的合成树脂材料或类似材料整体地模制,以便形成一包括相对地取向的侧壁14a和15a、 一顶部16a 和一底部17a的一件式结构。容器侧壁14a和15a可侧向变形,以对容器2a的内部加压和减压,它最好具有足够的弹性或刚性,以便在释放作用于容器2a上、以从其中分配液态产品18a的任何外力时,能自动地恢复其原有的形状。所示的容器顶部16a(困加-21)包括一颈部20a,它在不分配时通常处于向上打开的取向并限定了一排放口21a,在该排放口的四周设有分配阀3a的边缘部分".颈部20a的自由端包括一纵向截面大体为L形的环形沟槽22a,其形状=^做成有紧密#其中接纳阀3a的边缘部分4a, 阀的固定环23a设在沟槽22a的附近并由一按锁结构固定在容器2a的颈部20a上。容器支座17a有一J^上扁平的环形外底25a,它适于对抵地支承分配包装la,使其直立在一有关的表面诸如对顶、凹座、工作表面或类似物上.在图20-23所示的分配包装la中,与前面所描述的在分配包装l(图1 - 17)中通常处于隐蔽状态的阀3相反,分配阀3a在分配包装la内处于一M伸出的状态.参看图17 — 19,所示的分配阀3a与前面所描述的分配阀3大体相似, 而且包括一边缘部分4a、 一在其中具有一排放孔6a的头部5a和一连接套筒7a,该套筒的一端与边缘部分4a相连,而相反的一端则与头部5a 相连。连接套筒7a具有可弹性变形的结构,这样当容器2a中的压力升高,超过一预定值时,阀3a的头部5a如图22和23所示向上移动,以便从其分配液态产品18a.与前述的分配阀3(图1 - 17)相反,分配阀3a 的连#^筒7a并^f^并滚动3ik^伸,而是简单地向夕傳动,以这#"^种方式向阀头5a上作用打开力,即,使孔6a迅速打开,这将在以后详细描述。图示分配阀3a的法兰或边缘部分4a(图17 - 19)有其截面构形大致为三角形的环形形状,它包括一上缘38a、 一外缘31a和一底缘32a。阀3a 的边缘部分4a有一在顶缘30a和底缘32a之间的厚度,它在安装固定环23a时弹性地受压,在其间形成一可靠的防漏密封.所示的分配阀3a的头部5a(图17 - 19)有一圆的平面形状和一大体为带化变的结构,它在阀头5a的径向外部私導,而在其沿径向的内部较薄。这种带化变的结构有助于实现阀3a的i^il打开/i^关闭动作,这将在下文中说明。更具体一起,在图示的例子中,阀头5a有一外侧或外表面38a, 它有一朝周围环境向外打开的弧形的侧视立面结构,并由一第一预定半径限定。阀头外表面38a在连接套筒7a的外侧壁之间连续地延伸。阀头5a还包括一内侧或内表面39a,它有一边缘部分40a并由一笫二预定半径限定,该边緣部分具有朝分配包装la的内部向内弯曲的弧形的侧视立面结构.内表面39a上的边缘部分40a的半径大于外表面38a的半径, 这样两个表面在孔6a处或在孔6a附近朝阀头5a的中心会聚,并提供阀头5a的上述向内倾斜的结构.阀头5a的内表面39a还包括一中心部分41a,它有一圃形的平面形状,并具有基本上是平面的或扁平的侧视立面结构,其取向大体垂直于排放孔6a.如下所述,阀头5a的中心部分41a 有助于改善阀3a的打开和关闭特性,阀头5a有一圆形的边缘42a,它在边缘部分40a的外沿43a处开始并从该处以小的锥度向外延伸,最终汇合在连接套筒7a中.阀头5a的边缘42a与连接套筒7a的相邻的上部沿径向向内地隔开一粉巨离.边缘部分40a的靠内段与头部5a的中心部分41a限定了一圆形的边缘44a.图示分配阀3a的连接套筒部分7a的纵截面形状大体为J形,它包括一其形状为笫一腿部46a的环形基部和一其形状为杀二腿部45a的径向向内的圃柱形側壁部分。连接套筒7a有相应的内表面47a和外表面48a,它们沿其长度等距离地隔开,以使连接套筒7a有M上均匀的厚度。连接套筒7a的一端49a与阀3a的头部5a相连,连接套筒7a的相对端50a与阀3a的边缘部分4a相连.连接套筒7a的第一和笫二J5t部46a 和45a以为锐角的夹角互相取向,该角度在连接套筒腿46a和45a的外表面之间量得,并在图19中用希腊字母"6"注出。连接套筒腿部46a 和45a在一弧形部分51a处彼此连接,这将在从容器2a中分配产品时有利于阀3a的头部5a的运动。在困17-19所示的例子中,连接套筒7a的第一i&部46a短于第二腿部45a,其间的夹角在65-85度的范围内,还有,连接套筒7a的第一腿部46a以相对于头部5a经过缝56a延伸的中心轴线的一锐角取向。阀3a的外缘42a大体上是平坦的,其取向基本上平行于头部5a的中心轴线。连接套筒7a的第二腿部45a以与头部5a的中心轴线成一锐角的角度取向,该角度在2-10度的范围内。图示的分配阀3a的连接套筒7a在腿部46a的顶部有一倒J形端部49a,它成弧状地延伸至阀3a的头部5a,以在从容器3a中分配产品时进一步协助头部5a的运动.如前所述,阀头5a的外緣42a与连接套筒腿45a上端的内表面隔开一彭巨离,阀头5a和连接套筒7a之间的间隔有助于在^目联的容器中以一种在下文中将要详迷的方式分配产品时向网头5a施加转矩。连接套筒腿部45a的倒J形端部49a环绕大约108度,以在外表面38a的外缘附近固定在阀头部分5a上。在工作时,分配包装la按下列方式工作,阀3a通常采取图20中所示的向外突出的取向,其中,阀3a基本上保持其原有的模制形状,没有变形,并且大部分连接套筒7a和闽头部分5a从固定环23a向外突出, 当如困示的顶部分配包装la中所示的那样将阀3a装在容器2a的顶部上时,阀3通常不会受到由液态产品18a作用在其上的液力水头压力,为了从包装la中分配出液态产品18a ,使用者首先将容器2a倒过来, 使其成为图21-23中所示的顶部向下的取向.排放孔6a的位置最好在要分配液态产品18a的地方的正上方或与i^t齐.然后,〗吏附加的压力与容器2a的内部连系,诸如用手使容器侧壁14a和15a向内弯曲.如图22所示,连##筒7a使阀3a的头部5a开始沿轴向向外地朝分配包装la的外部变动。连接套筒7a的J形结构有助于阀头部分5a的轴向移动, 连接套筒7a从其原有的模制形状的弹性变形在阀3a中产生一复杂的应力模式,它将套筒弹性地推回至其原有的或正常的形状,这些力包括一由连接套筒7a作用在头部5a上的向外的转矩,它力图将排放孔6弹性地推向其打开位置.当使附加压力与容器2a的内部连系时,阀3a的头部5a通过连接套筒7a的进一步的纵向伸张和阀头5a的平面形状的进一步扩大继续向外移动,以一种与在上面对分配阀3详细描述过的方式相似的方式迅速打开至图23所示的全开位置,由于第二腿部45a的上端连在头部5a上, 与其外表面38a相邻,故当阀头部分沿轴向向外移动时,有一转矩作用在阀头5a上,它力图使阀孔6a迅速打开。第二腿部45a的倒J形部分49a协助将这些打开力有效地作用在阀头部分5a上。参考标号3b(图24)、 3c(图25)、 3d(图26)、 3e(图27)和3f(图28)总的代表本发明的附加的其它实施例,它们具有稍微不同的分配阀结构。由于分配阀3b-3f与前面所描述的分配阀3和3a才目似,在闺1 - 23和24-29中出现的相似部分分别用同样的对应参考标号代表,只是在后者的参考标号中分別加有尾标"b,, - "r .与前述的分配阀3a相似,每个分配阀3b-3f都是专门为顶部分配容器设计的,并且以同样的方式工作,更具体一些,分配阀3b与分配阀3a相似,只是分配阀3b的头部内表面40b全部为弧形,没有分配阀3a 的圆的中心部分41a,阀头内表面40b的半径大于阀头外表面38b的半径,这样阀头5b有一坡形结构,它在排放孔6a处较薄,分配阀3c与分配阀3b相似,只是阀头5c的两个相对表面40c和38c 是平行的,而且有相同的半径,这样头部5c有M上均匀的厚度,分配阀3d与阀3c相似,只是连接套筒7c的上端直接连在相关联的头部5d 上,没有岡3c的倒J形部分49c,分配阀3e与阀3a相似,只是连接套筒7e的上端直接连在头部5e上,没有阀3a的倒J形部分49a,分配阀3f与阀3a相似,只是头部5f的内表面40f有一靠近孔6a的正方形,而不是阀3a的圃形44a,参考标号3g(图30)、 3h(图31)和3i(图32)总的代表体现本发明的附加的其它分配阀.由于分配阀3g-3i与前述的分配阀3-3f相似,因此用相同的对应参考标号代4^图30-32中出现的相似部分,只是在后者的参考标号中分別加有尾标"g" - "i"。与阀3相似,每个分配阀3g -3i都是专门为底部分配包装设计的,并且以同样的方式工作。更具体一些,分配阀3g与前述的阀3相似,只是阀头5g的相对的表面38g和40g是截头锥形的,并且倾斜至与排放孔6g相邻的中心圃形区80和81。分配阀3h与前迷的分配阀3g相似,只是头部5h的相对表面38h和40h 在排放孔6h处相交,这样它们便没有分配阀3g的圃形区80和81。分配阀3i与前述的分配阀3h相似,只是头部5i的外表面40i是平坦的,其取向大体垂直于阀3i的中心轴线。在上述描述中,那些本领域中的技术人员将很容易地认识到,可以在不背离此处公开的概念的前提下对本发明作出改进.这种改进都被认为是^r在下列似yi"求中的,除非这些4W决求明确械明^J,沐所指的。
