本发明涉及一种可密封容器，以及密封这种容器的方法。特别地，本发明涉及一种无菌可密封容器，以及用于所述容器的无菌密封和相关的无菌包装设备。
背景技术
以无菌方式填充预消毒容器是已知的，并且采用了各种利用不同填充设备、不同容器和不同消毒技术的系统。一般地，在要被填充的容器的制造过程中，消毒所述容器的内部。在填充过程中，打开所述容器的入口，用装填管嘴将流动物料填入所述容器中。接着封住所述入口，将所述流动物料装于所述容器中，直到需要倒出所述物料。在填充后，所述容器的再次封闭必须恰当，以保证在随后的储藏和运输过程中不会发生污染。
为解决上述问题，美国专利US 4,257,535(申请人为Mellett)、US 4,672,688(申请人为Kalkipsakis)和US 4,805,378(申请人为Anderson)提出了一些设备和方法，这些专利公开了具有可密封容器的系统，所述容器具有从容器内部封住的装填口。
美国专利US 4,257,535和US 4,672,688公开了一种带有与容器壁为一体的内翼片的容器。填充容器后，推进所述翼片、使其紧靠装填口的边缘，并用位于容器外的加热设备加热密封所述翼片和所述装填口，以形成环形热封，从而封住所述装填口。美国专利US4,805,378公开了类似的设备和方法。在相关领域的其它专利申请中，没有使用内膜，而是用柔性容器本身的后壁形成焊接封闭。
美国专利US 4,257,535，US 4,672,688和US 4,805,378中，密封所述装填口的温度范围一般是160～225℃，具体温度依材料性质和所述容器后壁和翼片或膜的组合厚度而定。
上述专利文献提供了一般在水果和蔬菜浆、汁和奶制品的无菌或常规包装中使用的填充方法。
当用现有的设备和方法来装填上述的纤维和粒状产品时，如果不把纤维材料和颗粒截留在所述密封之内或越过所述密封，将难以获得理想的热密封。现有技术的另一个缺点是：由于能够采用的、不损害外包装层的外部热源最高温度的限制，热从所述外部热源传到所述包装内所需要的时间会延长。
现有技术的进一步缺点是当采用其它密封方式如超声密封来代替热密封时，所用的超声换能器会损害现有技术中设定为开启的容器的最后面的壁，并且不能实现所述内膜和所述装填口之间的理想密封。当在传统热封方法的环面或类似条件下实现密封时，在中间材料层之间，实现密封所需要的摩擦能会渐渐消失。
本发明的说明书中所有关于文献、出版物、行为、设备、物质、论文、材料或类似事务的讨论均服务于同一目的：为本发明提供上下文依据。所有这些描述均不应被理解为构成现有技术基础的主旨，或本发明优先权日以前与本发明技术领域有关的相关技术领域的公知常识。

具体实施方式
以下描述本发明的可密封容器的优选实施例。为便于理解本发明，在对附图的描述中运用了附图标记，附图描绘了现有技术中的密封管和本发明优选实施例的密封管。
图1a至图1d展示了现有技术中的典型设备——用于密封容器的密封管10。现有技术的密封管10为管状，密封至包或容器12，该容器12一般包括由一层或多层塑料薄膜层构成的前壁14，和由一层或多层塑料薄膜层构成的后壁16。所述密封管10具有底部边缘18，该底部边缘18的外表面被密封至所述容器12的所述前壁19。塑料薄膜20部分连接至所述底部边缘18的内表面21的区域23、24上。
在本例中，所述密封管10进一步包括密封在该密封管10的顶部边缘27上的可破裂膜25，该可破裂膜25位于所述容器12的外部、将所述容器保持在无污染状态，以使所述容器12可用于无菌装填。
如图1b所示，翼片膜20使得流体流过密封管10和膜20之间的区域29。该区域29为热密封闭合的区域，所述密封通过处于密封管10的底部边缘18的内平面21和膜20之间的环形接触区域形成。
图1c中，所述翼片膜20封住现有技术的密封管10，从而封住所述容器12。环形铜质加热元件30被置于所述后壁处，先不与该后壁直接接触，直到容器12被装填好且准备密封时才使加热元件30与所述后壁直接接触。如图1d所示，使所述加热元件30从容器12的后方向前推进，该加热元件30将容器12的所述后壁16推向所述前壁19，从而使得所述翼片膜20在区域32处与所述最内侧边缘21邻接。这使得所述翼片膜20与所述最内侧边缘熔合在一起，从而形成环形密封、封住所述容器12。用35表示宽的环形密封接触区域和熔体流上的压痕。需要通过热密封器30将足够的热和压力施加到所述容器12的后壁16的外层上，以实现翼片膜20的理想密封效果。在现有技术的其它实例中，可将所述容器的后壁16用作所述翼片。这需要将所述加热元件30定在所述密封位置一段时间，以封住所述容器12。
图2a至2f为处于容器51中的根据本发明第一实施例的密封管50。该密封管50具有流体通道52，流动物料如液体、悬浮液、浆状物等通过所述流体通道52进入容器51内。所述容器51具有前壁54和后壁56。所述密封管50包括底部边缘58，该底部边缘58的外表面密封至所述容器51的前壁54。所述底部边缘58的内表面59为翼片膜61提供了密封区59。在装填之前，所述密封管可以由盖在所述通道52上的膜53封住。
翼片膜61盖在所述密封区59上，以上述现有技术中类似的方式，在所述加热元件30的热的作用下，所述膜61完全密封至所述密封区59。
所述密封区59包括具有凸起截面的可变形突起64，如图2b所示，更详细地如图2f所示。所述密封区具有一定宽度，该宽度与所述环形加热元件30的最上侧表面30A的宽度和所述密封管的侧壁的宽度相对应。
所述可变形突起64的形状和尺寸使得当所述密封膜61在热压下紧靠住所述可变形突起64时，由与所述密封区59的其它部分相对而言可变形的突起64形成初始熔化区或加热区。进一步加压，所述可变形突起64相对于所述通道52径向压缩和膨胀，从而被压平、以提供翼片膜61和密封区59之间的完整密封。
图2e为预密封状态下的密封管50的仰视图。图中部分绘出的翼片膜61可通过密封区59上的熔接线65、66附加上去。所述翼片膜被拉紧、盖住所述可变形突起64以及所述熔接线65、66之间的区域。
由于预封状态下所述翼片膜61通常只在所述熔接线65、66处与所述密封管部分连接，在装上灌装头(图中未示出)后，在作用于所述膜上的流体压力下，所述密封管的弹性边缘部分向下弯曲。所述密封管的弯曲在所述膜61和所述密封区59之间形成了一个空间，该空间构成了所述密封膜61和所述密封区59之间的流体的侧向通道，图中用箭头表示。
图2f为所述可变形突起64的一种实施方式，该突起64具有三角形横截面，顶部尖角67构成切削刃。存在于所述密封区59和密封膜61之间的纤维的切断降低了纤维材料延伸通过形成于所述密封膜56和所述密封区54的表面之间的密封的发生率，从而降低了此类纤维对所述密封的完整性造成危害的可能性。这提供了更可靠的密封。
在图2g所示本发明另一实施方式中，所述可变形突起64为梯形截面，具有平的顶部68。这种截面有助于在马上要开始密封过程之前将任何可被截留在所述膜61和所述密封区59之间的纤维材料或其它粒料推离所述密封区域。来自加热元件的热和压力结合起来，使所述突起变形，将所述物料推离所述密封区域。
在图2h所示的本发明另一实施方式中，所述可变形突起64具有圆弧形截面71，这种截面也有助于在密封过程中将含纤维和颗粒的材料推离所述密封区域。
在本实施例中，所述可变形突起64可形成环形唇缘，该环形唇缘环绕所述密封管50的所述通道52延伸。所述环形唇缘不需连续，为不连续实体形式即可，在施加热和压力时，所述环形唇缘整体变形而形成所述密封区59。在替代的实施例中，可存在一个或多个连续或不连续的环形唇缘，在加热或加压时，所述环形唇缘形成所述密封区59的表面。
此外，所述环形唇缘具有可将种子或果仁等颗粒推离密封起始区域的附加特征，从而至少在所述起始变形区域形成完全密封。通过确保所述密封区的至少一部分为完全密封，可有效而可靠地密封所述密封管。更进一步地，当所述热密封膜被推靠到所述环形唇缘上时，本发明实施例中的所述环形唇缘的所述三角形截面提供了将种子或果仁等向外推离所述初始熔化区的初始楔效应。
所述可选的可变形突起的各截面增强了所述突起的局部加热和变形，并有助于切断纤维材料和将微粒推离所述初始熔化区。根据不同实施方式采用的进一步优选的截面将进一步增强局部加热、从而提供更有效率和效果的成形密封。
图3a-3b进一步展示了本发明的密封管80的另一实施方式。所述密封管80具有流体通道82，并包括两个具有突起截面、同心分布的可变形突起84，86(相对于所述密封管的所述流体通道82呈同心分布)，该可变形突起84，86从所述密封区89上向外突出。
此外，当所述密封膜91在热与压力的作用下与所述可变形突起84，86邻按时，所述可变形突起84、86的形状和尺寸使得所述密封管80以与前述实施例中类似的方式被密封住。两个初始加热或熔化区由与所述密封区89的其余部分相关的可变形突起84、86提供，在热和压力的作用下，所述两个可变形突起84、86均向着所述密封区89的其余部分、呈放射状地向内和向外变形。
从图3c中可以看出，图3b中的密封管的可变形突起84、86可为三角形截面，其顶端的尖角95形成切削刃。本实施例中，纤维切断于密封区89和密封膜91之间，这降低了纤维材料伸入形成于密封膜91和密封区89的表面之间的密封的几率，从而降低了所述纤维危及所述密封的完整性的可能，以提供更可靠的密封。
在如图3d所示的本发明另一可选实施方式中，所述可变形突起84具有梯形截面97，在密封过程即将开始之前，这种截面有助于将落入膜91和密封区89之间的任何纤维材料或其它颗粒推离所述密封区域。来自加热元件的热和压力一起使所述突起变形，并将所述材料推离所述密封区域。
图3e所示为本发明又一种实施方式，图中所述可变形突起84具有圆弧形截面99，该截面也有助于在密封过程中将纤维和颗粒材料推离所述密封区域。
本发明通过为所述密封区59、89设置以可变形突起64、84和86的形式存在的局部加热区，可大大降低形成密封所需要的加热元件的温度。进一步地，也可大大减少用来形成密封的时间。作为选择，与现有技术相比，本发明可大大降低所需的温度和形成密封所用的时间；现有技术中，所需的加热元件温度为180-200℃，停留时间为1.5-4秒；而在采用本发明的密封管时，在同样的停留时间下，加热元件的温度可降低到140-150℃。
形成密封所用的时间可大大减少30％或更多。这意味着在密封过程中由于温度和压力的升高而对所述容器造成损害的几率降低了，且因密封周期的减小而降低了造成损害的几率。对可密封容器如那些容积为3-4升的容器而言，这意味着总装填和密封周期的显著降低。
如图3a至3c中所示的实施例中，所述密封管80的所述可变形突起84，86被设置为具有三角形截面的环形唇缘的形式，围绕所述密封管80的所述通道72伸出。
在图3a-3c和2a-2f所示的实施例中，所述可变形突起64、84、86从所述密封区59、89上突起约0.75-1mm，其顶端构成切削刃。所述唇缘的三角形截面优选为等边三角形，底边宽度约0.75-1mm。所述密封区的宽度范围优选为～3-5mm。本发明的一个显著优点是：本发明的密封管50、80提供了更可靠的密封，即使在加热装置或超声换能器未对准所述密封区59、89的情况下也是如此；在这种情况下，所述可变形突起64、84、86首先与所述加热装置或超声换能器接触，且翼片膜61、91处于所述加热装置或超声换能器和所述可变形突起64、84、86之间，该可变形突起64、84、86将形成初始熔化区，并先向着所述密封区表面59、89的其余部分变形，直到未变形的可变形突起的剩余部分与所述加热装置或超声换能器邻接时为止，接下来加热所述未变形的可变形突起并使之变形。
在现有技术中，当加热装置或超声换能器与密封管之间未对准时，需要大量的热、压力和时间来使最初接触和被加热的所述密封管的密封区变形到一定程度，使所述密封区的其余部分被接触和加热，从而形成合适的被加热面，以实现可靠的密封。当需要大量的热、极高的温度和压力时，所述密封膜和/或容器壁会被损坏或至少被部分损坏，这使得密封管的密封与本发明的设备和方法所能提供的相比不完全或很弱。
在容积较小的容器的装填过程中，密封容器所用的时间占了所述装填和密封周期的相当大部分；本发明在提供可靠密封的同时，大大降低了所述周期所用的时间，这就使得本发明在使用大容积或小容积的容器时，均可以允许密封周期中的对齐不那么理想。
根据第一和第二实施例，本发明的另一特征是所述环形唇缘至少可初步切断纤维材料，如前所述，这些纤维材料可能存在于所述密封区59、89之间。这降低了纤维材料伸入到形成于所述密封膜61、91和所述密封区59、89之间的密封之中的几率，从而降低了这些纤维危及密封完整性的可能，提供了更可靠的密封。
此外，所述环形唇缘具有附加特征，该附加特征可将种子、果仁或其它类似的颗粒材料推离密封起始区域，从而至少在初始变形区域形成完全密封。
通过确保至少在所述密封区的某一部分形成完全密封，就可将所述密封管有效而可靠地密封住。进一步地，如本发明实施例中所述的环形唇缘的三角形截面提供了初始楔效应，当所述热密封膜被推靠到所述环形唇缘上时，该初始楔效应使得种子或果仁等被向外推离所述初始熔化区。
还应说明，高压和本发明提供的形成于密封区59、89和密封膜61、91之间的减小的接触点表面积使得该两部分之间的传热被集中，与现有技术中更宽的接触面积相比，可更快速、有效地开始熔化和兼容材料的相混合过程。
此外，对于现有技术的密封管，其密封盖是单平面的，环形加热元件同样也是单平面的，任何的未对准，即加热元件和密封盖的各自平面不平行，均会危及所述密封的安全，或者会增加使所述密封完善所需要的时间和/或温度。在本发明中，当所述环形加热元件的平面不是均匀地平行于由所述凸起截面的顶部边缘所界定的平面时，在这种情形下，所述凸起截面在适当的热和压力下的快速变形会使其趋向于自校正。
所述注射成型密封管可由聚乙烯和一种高密度组分混合制得，所述聚乙烯的密度和性能范围从低密度、“线性低密度”到中密度不等。选择所述聚乙烯的密度以优化所述密封管的各项参数，包括刚性、柔性、熔融流动性和耐高温要求。
外包壁材料(bag wall material)可由多层构成，以提供所需的品质属性，即屏障功能、防潮性能、物理强度和热密封性等。
一般地，与产品接触的内层为各种形式的低密度聚乙烯，所述内层作为自由层，或者作为与聚酰胺(尼龙)层或聚酯层结合或层压的内层；在后一种情形下，形成的层压片也可包括附加层，如铝箔、PVDC(聚二氯乙烯)、EVOH(乙烯-乙烯醇共聚物)等，选择该层来实现阻气、防潮、遮光等性能。构成所述密封区59、89和所述密封膜61、91的材料在软化或熔化时可相混合，从而形成需要的密封。可使用许多材料，特别是热塑性聚合材料，如高密度聚乙烯(HDPE)。
所述密封区和密封膜一般由聚合材料构成，所述聚合材料在局部温度为130-200℃时流动，从而实现密封。不过，也可使用在局部温度低至100℃和高至265℃时仍可流动的材料来代替上述材料。
所述密封膜通常与不同规格的迭片结构相结合。所述膜的与所述密封管相邻接的内表面由低密度聚乙烯材料制成、将热密封至所述密封管。所述膜的另一侧由某一级别的聚酯(PET膜)制成，该级别的聚酯不会熔化或热密封至在指定温度下使用的任何聚乙烯材料。
与相关技术相结合，所述密封膜可脱离所述密封区表面，并可以以容器内的翼片膜的形式存在，或者甚至可以作为容器壁的一部分，这些都属于本发明的范围和精神之内。
可设置可破裂膜53、93，从而使本发明可用于无菌装填过程，形成的密封可为气密封(hermetic seal)，以使所述容器能够保存食物或饮料等。
所述密封管、密封膜和外包也可用各种其它材料制成，例如，所述材料可以使用可用于液体包装的聚碳酸酯、聚氯乙烯、聚丙烯和其它薄膜，其形式或者为单一薄膜，或者为共挤或层叠而成的组合材料，监测该组合材料的相关熔点和彼此间的热密封性，使其适于使用。
必须说明，本说明书所公开和定义的发明应扩展至由文本和附图所描述的两个或多个单一特征的所有可选组合。所有这些不同的组合构成本发明的不同实施方式。
还必须说明的是本说明书和权利要求书中所用的词语“包括”(或其变换形式如“包含”等)不能被理解为排除了其它元件或特征的存在。

18.如权利要求16或17所述的密封管，其特征在于：所述可变形突起为三角形截面，三角形的顶点构成切削刃。
19.如权利要求16至18中任一项所述的密封管，其特征在于：所述密封管还包括可破裂膜，该可破裂膜在破裂之前盖住所述通道的外部开口，从而在装入物料之前密封住所述密封管的所述通道。
20.如权利要求19所述的密封管，其特征在于：所述密封管可与流体运输装置相接合，所述可破裂膜在所述密封管与所述流体运输装置接合时破裂。
21.容器的密封管的密封方法，该方法包括以下步骤：
-提供具有前、后壁的容器，所述前、后壁构成一个空腔，所述前壁上载有密封管，该密封管具有第一端、第二端和位于该第一、第二端之间的通道，所述密封管包括位于所述容器内、用于接纳热密封膜的密封区，所述热密封膜可被热密封至所述密封区、形成连续密封，所述密封区在预密封条件下包括至少一个具有凸起截面的突起，该突起提供与所述密封区的面积相比面积减小的初始熔化区或初始加热区；
-提供热密封膜，该热密封膜与所述密封区相邻，并盖住所述密封管的所述通道；
-用加热装置通过所述容器的后壁对所述热密封膜进行加热，并将所述热密封膜和所述密封区彼此相向推进；
其中，所述可变形突起被设置为当其与所述热密封膜邻接时，所述可变形突起和所述密封膜的热塑性层被熔化、形成所述热密封膜和所述密封区之间的密封，从而封住所述通道。
22.如权利要求21所述的方法，其特征在于：所述加热装置向所述可变形突起和所述密封膜提供传导和/或对流传热。
23.如权利要求22所述的方法，其特征在于：所述加热装置可通过摩擦能量或超声能量来加热所述可变形突起和所述密封膜。
