Description
技术领域
本发明一般地涉及一种可用于包装食品的包装系统,且更具体地涉及一种烘焙研磨咖啡的包装系统,其具有带可视指示器的顶盖。
背景技术
用户通常想要食品的外观(尤其是烘焙研磨咖啡)在消费时是新鲜的。包装系统例如咖啡容器,并且更特别的是塑料咖啡容器(例如转让给Procter&Gamble公司的美国专利No.7,169,418中所述的那些咖啡容器),正在被越来越多地用于将咖啡交付给消费者。随着在塑料容器中出售给消费者的咖啡的增加,存在对于容器内部的咖啡是否新鲜的指示的消费者需求。新鲜度的指示器包括可视指示器,其为消费者提供了他们即将消费的咖啡将满足他们对一杯令人愉悦的咖啡的期望的信心。消费者知道外部环境因素,例如空气(包括氧气)会影响新鲜度,并因而影响烘焙研磨咖啡的味道。当前的容器没有为消费者提供这些可视指示器以告知他们容器不仅仅提供了一种运输烘焙研磨咖啡的途径,而且还提供了烘焙研磨咖啡真正新鲜的指示。
此外,从消费者研究中已知新鲜度在咖啡市场中是一项关键的消费者需求。换句话说,新鲜的咖啡等于一杯极具风味的咖啡。当前,用于处理和包装咖啡的方法确保在消费者从商店购买咖啡时咖啡仍然是新鲜的。一旦咖啡被购买并放至存储和消费的地方(典型地是消费者的家中),消费者仍然希望在消费全部数量的咖啡所花费的时间长度内咖啡在容器中保持新鲜。不幸的是,在顶盖和容器之间的配合不够紧密来通过气密性密封而有效地“封入”新鲜度,或者甚至使包装“排气”,即在顶盖的顶部上推动以将空气挤出容器,而后将顶盖密封在容器上,使得长时间保持轻微的真空,指示没有空气进入到容器中。即使配合已经足够紧密,对于消费者而言要看见压下的顶盖(由于压力差,即真空)仍将是很困难的,因为压力差小,而盖子的表面积大,因而导致顶盖小的挠曲。
因此,存在对于用于烘焙研磨咖啡的包装系统的需求,该包装系统包括用于指示气密性容器以及容器内部存在真空的可视指示器。因而,烘焙研磨咖啡的新鲜度被告知消费者。
发明内容
为了解决当前需求,本发明构想了一种用于烘焙研磨咖啡的包装系统。该包装系统包括容器、柔性顶盖和可视指示器。可视指示器指示在包装系统的内部和包装系统的外部之间的压力差。该包装系统还可包括封闭件和单向阀。在顶盖和容器之间可形成气密性密封。在一个实施例中,顶盖可以是圆形的。在另一实施例中,顶盖的直径标称上可以是六英寸。
在一个实施例中,可视指示器可与顶盖一体地结合。在另一实施例中,当在容器的内部和容器的外部之间存在真空时,可视指示器可至少部分地向内朝容器内部凹入。在又一实施例中,可视指示器可包括气泡部分,并且还可包括凸起部分。可视指示器可包括热塑性弹性体。在另一实施例中,可视指示器可具有第一位置和第二位置,第一位置包括从容器的内部向外凹入的气泡,第二位置朝容器的内部向内凹入,其中当容器内存在真空时,可视指示器采取第二位置。
在另一实施例中,包装系统还可包括位于容器和顶盖之间的交界处的垫圈。该垫圈可包括热塑性弹性体,该热塑性弹性体可以是半透明的。
在一个实施例中,顶盖可由塑料材料制成,该塑料材料选自包括聚碳酸酯、低密度聚乙烯、高密度聚乙烯、聚对苯二甲酸乙二醇酯、聚丙烯、聚苯乙烯、聚氯乙烯、它们的共聚物以及它们的化合物的组。
在另一实施例中,该包装系统还可包括容器内的烘焙研磨咖啡。
在根据本发明的第一优选实施例中,提供一种用于包装食品的包装系统,包括:容器,其包括开口的顶部、封闭的底部以及主体部分;具有表面区域和中心的柔性顶盖,其构造成可移除地附接在容器上,并构造成被最终用户或消费者定期下压以便将空气挤出容器;封闭件,其可移除地附接在容器上,并包括单向阀;可视指示器,其设置在柔性顶盖上并且与柔性顶盖一体地结合;其中,该可视指示器包括具有表面区域的气泡部分和包围该气泡部分的外环部分;其中,当将顶盖应用于容器上时,可视指示器的气泡部分从容器的内部向外凹入,其中,在柔性顶盖被最终用户或消费者下压以便将空气挤出容器后,可视指示器的气泡部分采取至少部分朝向容器的内部向内凹入的位置,以便由此指示包装系统的内部和包装系统的外部之间的压力差,其中,可视指示器的气泡部分与柔性顶盖的中心不重合,以及其中,可视指示器的气泡部分的表面区域实质上小于柔性顶盖的表面区域。
在前述第一实施例中,优选地,当容器的内部和容器的外部之间存在真空时,可视指示器的气泡部分至少部分地朝向容器的内部向内凹入。
在前述第一实施例中,优选地,可视指示器还包括凸起部分。
在前述第一实施例中,优选地,包装系统还包括在容器和顶盖之间的交界处的垫圈。
在前述第一实施例中,优选地,顶盖由塑料制成,该塑料选自包括聚碳酸酯、低密度聚乙烯、高密度聚乙烯、聚对苯二甲酸乙二醇酯、聚丙烯、聚苯乙烯、聚氯乙烯、它们的共聚物以及它们的组合物的组。
在前述第一实施例中,优选地,可视指示器包括热塑性弹性体。
在前述第一实施例中,优选地,食品包括烘焙研磨咖啡。
在根据本发明的第二优选实施例中,提供一种用于包装食品的包装系统,包括:容器,其包括开口的顶部、封闭的底部以及主体部分;具有表面区域和中心的柔性顶盖,其构造成可移除地附接在容器上,并构造成被最终用户或消费者定期下压以便将空气挤出容器;封闭件,其可移除地附接在容器上,并包括单向阀;可视指示器,其设置在柔性顶盖上并且与柔性顶盖一体地结合;其中,可视指示器具有第一位置和第二位置,所述可视指示器包括具有表面区域的气泡部分和包围该气泡部分的外环部分,在所述第一位置,所述气泡部分从所述容器的内部向外凹入,在所述第二位置,所述气泡部分向着所述容器的内部向内凹入;其中,在柔性顶盖被最终用户或消费者下压以便将空气挤出容器后,可视指示器的气泡部分采取第二位置,其中,第二位置指示容器内存在真空,其中,可视指示器的气泡部分与柔性顶盖的中心不重合,以及其中,可视指示器的气泡部分的表面区域实质上小于柔性顶盖的表面区域。

附图说明
虽然本说明书包括本发明的描述,并以限定本发明的权利要求做结论,但是相信这两者将通过参照附图而更好地理解,其中:
图1是包装系统的分解透视图。
图2是包装系统的透视图。
图3是包装系统的特写透视图。
图4是可视指示器的侧视图。
图5是可视指示器的另一实施例的侧视图。
具体实施方式
为了促进理解本发明的原理,现在将参照附图中所示的实施例,并使用特定的语言来描述实施例。然而应该懂得,并非因此意图限制本发明的范围。在本发明的范围内可构思本发明相关领域的技术人员通常将会想到的所示装置的此类变化和进一步的修改,以及其中所示的本发明原理的此类进一步应用。
虽然本文将根据用于食品例如烘焙研磨咖啡的包装来大致描述本发明,但是应该懂得用于食品的任何合适的包装系统都在本发明的范围内。本文所用和所述的可视指示器对于任何产品可能都是有用且有利的,其中指示容器内部存在真空是有价值的或至少是合乎需要的。
如本文所用,包括“该”、“一”和“一个”的用语在权利要求或说明书中使用时,应理解为意味着一个或多个所要求保护或所描述的事物。
如本文所用,用语“包括”、“包含”以及“包括了”意味着非限制性的。
如本文所用,用语包装系统的“排气”被限定为根据本发明的一个实施例当最终用户或消费者在包装系统的顶盖的顶部上推动以将空气挤出容器,且随后将顶盖密封或附接在容器上,从而在包装系统内产生轻微的真空时的情形。因此,“排气”导致过量的大气气体从容器中排出,并因此减少了容器内部存在的空气的量,以及因而减少氧气的量。
本发明涉及一种用于烘焙研磨咖啡的包装系统。该包装系统可包括容器、顶盖和可视指示器。可视指示器可指示在包装系统的内部和包装系统的外部之间的压力差。烘焙研磨咖啡的消费者敏锐地意识到咖啡容器需要阻止空气进入容器,以便保持烘焙研磨咖啡新鲜。因此,此可视指示器可为消费者提供简单但清楚的可视信号,即容器已经被正确地关闭、排气,并是气密性的,且处在轻微的真空下。
图1详细描绘了根据本发明的一个实施例的包装系统10。包装系统10通常包括由塑料例如聚烯烃制成的容器11。包装系统10大体上与美国专利No.7,169,418和7,169,419中所公开那些包装系统相符,这些专利通过引用而完整地结合在本文中。应该懂得,容器11可采用多种形状,非限制性的示例包括圆形、方形、平行六面体,并且包括或没有手柄、把手或贯通型手柄,并且可由多种合适的材料制成。容器11通常包括开口的顶部12、封闭的底部13和主体部分14。开口的顶部12、封闭的底部13和主体部分14限定了在其中包含产品(例如烘焙研磨咖啡)的内部容积。
进一步参照图1,容器11可以圆柱形地成形,具有大体上平滑的侧面。在另一实施例中,容器是平行六面体形状。手柄部分15可分别在拱形位置处形成在容器主体部分14中。另外,容器11可具有呈轮缘状结构的隆起17,该隆起17设置在容器11的开口端处。隆起17可提供用来可移除地附接封闭件18的表面,并且可提供用于顶盖30的裙状部分32的锁定表面。
再次参照图1,呈轮缘状结构形式、设置在容器11的开口端处的隆起17可具有设置在其上的纹理化表面。设置在隆起17上的纹理化表面可包括呈隆起形式的凸起表面、环形特征、和/或网纹,以促进可移动封闭件19的更好的密封。环形特征可包括单个珠缘或一系列珠缘,作为从隆起17的密封表面凸出的同心环。虽然不希望受到理论的束缚,但是应该懂得,隆起17上的纹理化表面可容许在密封处理期间应用更均匀和/或更集中的压力。由于在制造容器11期间的铸造、修整、运输过程中引入的任何不规则性,纹理化表面可提供隆起17和可移动封闭件19之间增加的密封能力。应该懂得,虽然图1以及其它实施例公开了隆起17,但是可设想没有隆起的包装系统且其在此发明的范围内。
此外在图1中,包装系统10可包括封闭件18。封闭件18可以是叠层的可剥离的密封件19,该密封件19可移除地附接并密封在容器11上。可剥离的密封件19可具有在下面的孔,如标号20所示的孔,该孔可应用除气阀。单向阀20可被热焊接或胶合在可剥离的密封件19上。
封闭件18可沿着容器11的轮缘或隆起17而密封在容器11上。密封方法包括热密封方法,该方法结合热的金属板,该金属板穿过封闭件材料和容器轮缘应用压力和热量,导致熔合的粘结。所达到的剥离强度通常是密封过程所施加的压力、温度和停留时间的结果。然而,本领域技术人员应该懂得,可使用其它类型的密封件和密封方法来实现具有充分且有效的密封强度的粘合,包括但不限于设置在轮缘17上的多个环形密封珠缘。
再次参照图1,包装系统10可包括顶盖30。顶盖30可包括圆顶部分31、裙状部分32和肋条33。顶盖30可构造成可移除地附接在容器11上。作为非限制性的示例,顶盖30通常由具有低挠曲模数的塑料制成,例如线性低密度聚乙烯(LLDPE)、低密度聚乙烯(LDPE)、高密度聚乙烯(HDPE)、聚乙烯(PE)、聚丙烯(PP)、线性低密度聚乙烯(LLDPE)、聚碳酸酯、聚对苯二甲酸乙二醇酯(PET)、聚苯乙烯、聚氯乙烯(PVC)、它们的共聚物以及化合物。这容许具有高柔性但仍可提供足够的刚性的顶盖30,以容许容器的连续堆叠。通过使用柔性顶盖30,便于在包装期间将顶盖30机械应用于容器11上以及在消费者打开之后将顶盖30再应用于容器11上。虽然不是排他的,但柔性顶盖30(特别是由上面选择的塑料制成的柔性顶盖30)的特征是最终消费者从容器11中“排气”出过量的大气气体,从而减少容器11内部中存在的氧气量的能力。另外,顶盖30所呈现的柔韧性和刚性的期望平衡会改变顶盖30的厚度剖面。例如,圆顶部分31可被制成比裙状部分32和肋条33更薄。
圆顶部分31通常可设计成具有曲率,且因而具有高度,以适应封闭件18随着包装产品(例如烘焙研磨咖啡)从容器11向外的位移,从而排出气体。圆顶部分31所需的曲率量可以数学地确定,作为封闭件18的位移的预测。作为非限制性的示例,对于标称6英寸(15.25cm)直径的顶盖,圆顶部分31的标称高度可以为0.242英寸(0.61cm),且封闭件18上的内部压力为15毫巴。此外,圆顶部分31通常还能够随着容器11中的内部压力上升而移动超出其原始高度,导致封闭件18在由单向阀20释放任何废气之前升高。虽然已经将圆顶部分31描述成设计具有曲率,但是可设想不具有曲率的其它实施例。简单的平坦设计也可能是合适的。
图2显示了根据本发明的一个实施例并包括可视指示器40的包装系统10的透视图。在此实施例中,包装系统10包括容器11,该容器11包括封闭的底部13、主体部分14、手柄部分15和顶盖30。顶盖30包括设置在其上的可视指示器40的一个实施例。在此特定实施例中,可视指示器40可作为薄的柔性隔膜而结合在顶盖30内,该隔膜形成了气泡,当将顶盖应用于即可移除地附接在容器上时,当容器内侧即内部和外侧即外部之间不存在真空即压力差时,该气泡向外凹入而远离容器11的内部。通常,可视指示器40可包括气泡。因而,当将顶盖应用于容器11上且不排气,并因而在容器内部和外部之间不产生压力差时,可视指示器40通常可位于包括并形成气泡的第一位置,该气泡从容器内部向外凹入。此外,在还没有应用于容器11的独立顶盖上,可视指示器40可包括并形成气泡。图3描绘了此类布置,其显示了一种包装系统10,该包装系统还没有经历由最终消费者实施的“排气”,这通过可视指示器40从容器11的内部向外凹入而得以证实。
在使用中,可视指示器40可如下充当给消费者的指示器。当最终用户使包装系统10“排气”时,最终用户或消费者在包装系统10的顶盖30的顶部上推动以将空气挤出容器11,且随后密封或按压在顶盖30上,以便将其应用于即可移除地附接在容器11上,从而在包装系统10中产生并长时间保持轻微的真空。此轻微真空指示容器内的压力小于容器外的压力。在此排气点上,可视指示器40通常可位于至少部分或完全朝向容器的内部向内凹入的第二位置,指示存在压力差,因为包装系统内的压力小于包装系统外的压力,具体地说在容器内部已经形成了轻微真空。如果没有足够好地执行排气以形成完全向内凹入的位置,可视指示器40还可为在平坦位置、基本平坦位置、部分平坦位置、以及在或不在平坦或基本平坦的条件下部分向内凹入和部分向外凹入的多种变型。本质上,可视指示器可取决于已经发生的“排气”的程度而处在任何构造方位上。因而,“排气”导致过量的大气气体从容器11中释放出来,并因此减少了存在的空气的量,以及因而减少了存在的氧气的量。因此,形成了真空,并导致可视指示器40由于容器内部的空气压力小于容器外部而被拉向容器11的内部,并且至少部分地向内凹入。在消费者执行了“排气”后,消费者就知道他们已经从容器中除去至少某些空气,且因而除去了某些氧气,并因而为咖啡准备了更友好的环境。因为已经从容器中除去了某些氧气,所以将较少发生咖啡的氧化,导致更新鲜的咖啡。可视指示器40本身为消费者提供了知道至少某些过剩的空气和氧气离开了容器的好处。其可通过保持此向内凹入的位置而进一步为消费者提供没有空气回到容器中的好处。因而,如果在包装系统中出于某些原因不存在真空,消费者将能够识别此情形,因为可视指示器40将向外凹入,并且他或她将能够使包装系统“排气”,并因而使包装系统返回更新鲜的状态,该状态处于部分真空下,如向内凹入的可视指示器40所示。因此,不仅消费者可定期使包装系统排气,例如每天早晨在他们使用包含在包装系统内部的烘焙研磨咖啡时,而且他们还可在任何其它时间,在他们观察或另外的注意到可视指示器40处于相对容器11的内部向外凹入的位置时使包装排气。因此,消费者可比仅在使用容器期间更多地保存咖啡的新鲜度,在使用容器期间,消费者通常将使包装系统“排气”。
图3详细描绘了根据本发明的一个实施例并包括可视指示器40的包装系统10的特写透视图。包装系统10同样包括容器11,该容器11包括封闭的底部13、主体部分14和手柄部分15。此外,可视指示器40显示成与顶盖30一体结合。可视指示器40显示成从容器11的内部向外凹入,并因而显示为气泡。同样,因为可视指示器40向外凹入,所以包装系统10还没有被最终消费者“排气”,或者更具体地说容器11内不存在真空。
前文和后文所讨论的本发明的实施例中所公开的可视指示器可呈多种构造。图4详细描绘了根据本发明一个实施例的可视指示器40a的侧视图。可视指示器40a包括凸起部分41、气泡部分42和外环部分43。当使用可视指示器40a,并且包装系统10的内部因而处于真空下时,该情况如前文所述可发生在最终消费者进行排气后,气泡部分42、凸起部分41或这两者可向外凹入。因而,可视指示器40a可构造并设计成使得当容器内部存在真空时只有气泡部分42向内凹入,或者当容器内部存在真空时只有凸起部分41向内凹入,或者当容器内部存在真空时,气泡部分42和凸起部分41两者都向内凹入。如之前所述,还可能是各个部分或这两部分都只是部分地向内凹入的情形。
外环部分43可提供从可视指示器40a的隔膜至顶盖30的过渡,使得可视指示器可与顶盖30一体结合。在一个实例中,当容器内部产生真空时,凸起部分41可迫使气泡部分42按照比如果不包括凸起部分41更显著的方式突跳(snap-through)。在没有凸起部分41的条件下,随着容器内部的压力升高回到大气压,并且因而真空减低时,气泡部分42可按比例升高。在具有凸起部分41的条件下,气泡在给定的真空下从向外凹入转变成向内凹入,但可随着压力上升而保持向内凹入,而不像没有凸起部分41时那样按比例升高。因而对于这两个实施例可产生两个不同的压力。
虽然在图4中显示了一种凸起和气泡构造的一个实施例,但是在本发明的范围内还有多种其它构造。那些包括所有形状、尺寸和构造的隆起和气泡,包括如附图所示的通常圆形的构造以及其它非限制性的示例,例如方形、椭圆形和三角形。
图5中可呈现至少一个其它构造。在图5中显示了可视指示器50。可视指示器50包括气泡部分51和外环部分52。它还包括侧面部分54。在此实施例中,其不包括如图4的实施例的凸起部分,气泡部分51形成了可视指示器50的峰值高度。
在真空指示器与顶盖一体结合的某些实施例中,可执行通过共注射模制的薄隔膜的模制。隔膜区域和可视指示器可用高度柔性材料制成,非限制性的示例包括热塑性弹性体(TPE),其可帮助集中轻微真空的效应,并因而导致指示器更大的偏转,使得如下情形对消费者更明显,即容器处于压力差下,并因而处于轻微真空下。
为了在顶盖和容器之间产生气密性密封,并因而容许在包装系统10进行“排气”时形成真空,在一个实施例中可使用热塑性弹性体(TPE)作为顶盖和容器之间的交界处的垫圈或密封件。对本领域技术人员已知为软接触材料的TPE可用于在容器和顶盖之间产生100%或几乎100%的气密性密封。当附接在顶盖上或形成于顶盖中时,TPE可变形并可在顶盖放置于容器上时与容器相符,并且这种布置可形成密封以防止空气进入包装系统。因而在消费者进行排气、并且可视指示器40处于其向外凹入的位置之后,在容器和顶盖之间可形成密封布置,从而没有空气进入容器中或进入容器中的空气最少。如果空气进入容器使得真空损失,可视指示器40将转变到其向外凹入的位置,指示真空的确损失了,这时可使包装系统重新排气。
在其它实施例中,TPE材料可以是至少部分或完全半透明的,使得其可用于产生颜色变化的密封件。在这些实施例中,当在容器和顶盖之间存在紧密接触时,在容器和顶盖之间的交界处的密封件可改变颜色。例如在一个实施例中,其中TPE材料是蓝色的,并且接触TPE材料的容器部分是黄色的,则密封件可转变为合成的绿色。利用用于TPE材料和容器的任何颜色可设想其它颜色布置,使得可形成任何合成的颜色。
在另一实施例中,可视指示器40可以是单独的器件,然后可在辅助操作中将其密封和/或附接在顶盖上。可设想设计和位置上的多种变化并处在本发明的范围内,因为优化真空指示器的视觉效果可以是放置可视指示器的进一步目的。在至少一个实施例中,可能需要最大限度地偏转或反转指示器,使得消费者可以很容易地确定他们已经在包装系统的内部和周围环境之间产生了压力差。因此,为消费者的可视化而优化指示器的位置也在本发明的范围内。
关于制造方面,如图1中所示,可通过聚烯烃复合物的吹塑成型而生产容器11。例如聚乙烯和聚丙烯是适合于食物接触的相对低廉的树脂,并且提供了优良的水蒸汽阻隔。然而,在本领域中已知这些材料不是很适合于包装需要长保存期限的对氧气敏感的食物。作为非限制性的示例,乙烯-乙烯醇共聚物(EVOH)可提供这种优良的阻隔。因而,在两个或多个聚烯烃层之间夹入一薄层EVOH可解决这个问题。因此,通过为使用的每种树脂加入额外的挤压机,可对多层结构使用吹塑成型工艺。另外,可利用其它方法来制造容器,包括注塑成型和延展吹塑成型。
本文公开的尺寸和数值不应被理解为严格地受到所述确切数值的限制。相反,除非另有说明,否则各此类尺寸都旨在意味着所引述的数值和该数值周围的功能上同等的范围。例如公开为“40mm”的尺寸旨在意味着“大约40mm”。
具体实施方式中相关部分所列举的所有文献通过引用而结合在本文中;任何文献的引用都不应被解释为其是关于本发明的现有技术的认可。至于本文献中的任何术语的涵义或定义与通过引用而结合的文献中的任何相同术语的涵义或定义有所冲突时,该术语在本文献中的指定的涵义或定义应起指导作用。
虽然已经图示并描述了本发明的特定实施例,但是本领域技术人员应该明白,在不脱离本发明的精神和范围的情况下可做出各种其它变化和修改。因此在所附权利要求中意图覆盖所有属于本发明范围内的这种变化和修改。
