Description

用于制备饮料的载体及其制造方法 技术领域
本发明涉及一种用于制备饮料的载体及其制造方法，尤其涉及一种一次性直冲式饮料载体的生产工艺。
背景技术
由于目前消费者对饮品的消费习惯的改变，现有一次性(One-serve)直冲式饮料载体(或俗称的“咖啡胶囊”)日渐受到消费者的欢迎，如以库里格

公司推出的

胶囊产品为例，其主要部件包括：一塑料容器、一固定于所述塑料容器内部的过滤件、以及一用于密闭所述塑料容器的开口的上封盖，其中所述过滤件本身或所述过滤件上表面至所述塑料容器的开口间，存在一用于贮存饮料介质(如咖啡豆粉)的上部空间，以及所述过滤件下表面至所述塑料容器的底部间存在一下部空间。所述现有饮料载体用于与一饮料冲制机(如库里格

公司销售的
Figure PCTCN2018107593-appb-000004
咖啡冲制机)搭配使用以冲制出消费者所需的饮料(如咖啡)。这种现有一次性直冲式饮料载体结构的多种示例可以参见美国专利号US5,325,765、US5,840,189、US6,607,762、US7,398,726、US9,750,370B2以及PCT国际公布号WO/2011/031294的公开。
然而，上述饮料载体的所述塑料容器大体上是以聚合物基的材料制成，特别是热塑性聚合材料，例如常见的聚乙烯(Polyethylene)、乙烯-乙烯醇共聚物(EVOH)或聚苯乙烯(Polystyrene)等。一般消费者使用完该上述饮料载体后，这类石油基塑料制成的所述塑料容器大多是直接作为垃圾丢弃而非回收，或者根本没有可见的回收通道可供回收，使得这类石油基塑料制成的所述塑料容器作为可再生资源(Renewable Resource)的难度以及成本很高，但是这类石油基塑料制成的所述塑料容器如果没有再生使用即大量丢弃，将对环境造成极大的破坏；其次，一般消费者经常地饮用这类热塑性塑料制成的所述塑料容器冲制的高温饮料(如以温度在100℃以上的热水冲制的咖啡或茶饮)，长期下来容易对人体造成健康上的疑虑以及食品的安全问题。之后，虽有厂商推出消费者能再度利用(Reuseable)或可再回收(Recyclable)的其它类塑料容器，例如以聚丙烯(PP,Polypropylene)制成的塑料容器，但这类同样是以石油基塑料制成的塑料容器依然会有造成人体健康的疑虑以及食品安全问题；况且，这对一般消费者是用完塑料容器就丢弃的习惯而言，在本质上无法实现生物可降解(Biodegradable)或可堆肥(Compostable)的环保 要求。
再者，通过成型产线大量生产若干个塑料容器后，为方便运输所述若干个塑料容器到其它条装配产线作部件装配，所述若干个塑料容器在运输前需要以头接尾的排列方式一个叠上一个，形成如同常见的‘叠杯’(Cup stacking)状态。之后，当成排的所述若干个塑料容器在通过其它条装配产线进行部件装配时，该装配产线需要通过自动取件设备从成排的所述若干个塑料容器中拔取所述塑料容器以进一步装配上对应的过滤件以及对应的上封盖，然而由于所述叠杯列中每两个叠合的塑料容器间叠合的深度与配合度是不一致的。若该配合度太松(或叠合的深度太浅)可能会形成滑动配合，造成其中任一所述塑料容器未被拔取前就自该叠杯列中脱落，从而出现塑料容器遗失的问题，或者因为每两个叠合的所述塑料容器的中心轴未能排列对齐而使上下歪斜，所述塑料容器无法被装配产线的自动取件设备精确拔取，导致装配产线的运行不顺畅，生产效率低；反之，如所述叠杯列中两个叠合的塑料容器间叠合的配合度太紧(或叠合的深度太深)如同达到过渡配合的程度，又容易使这两个叠合在一起的塑料容器一起被拔取，同样会造成该装配产线运行的不顺畅，生产效率低。更甚者，如果施加于两个塑料容器间的叠合压力过大，易使该两者间的该配合度过紧如同达到过盈配合的程度，甚至有可能造成所述塑料容器的杯身变形，沦为废品。在成排的所述若干个塑料容器中，如果部分塑料容器间叠合的配合度太紧，而另一部分塑料容器间叠合的配合度却又太松，这将使所述部件装配产线的自动取件设备无法通过相同的作用力精确地自成排的所述若干个塑料容器中抓取每一所述纸制容器。
故，有必要提出一种用于制备饮料的创新载体及其制造方法以解决上述现有技术的问题。

图7绘示的所述湿纤维纸塑工艺的一贯化自动化生产机台7的结构与运行的细部描述可以进一步参见中国实用新型专利申请号CN201820101475.3的介绍，但需注意的是，这仅是本发明所采用的湿纤维纸塑工艺的一贯化自动化生产机台的其中一个示例，不因此限定必须使用如图7绘示的所述湿纤维纸塑工艺的一贯化自动化生产机台7。因为在其它实施例中，任何能用于实现本发明的所述纸制基材20的所述立体几何造型的一体形成与自动化的大量生产的湿纤维纸塑工艺的一贯化自动化生产机台皆能采用。另，还需注意的是，中国实用新型专利申请号CN201820101475.3的公开是应用于生产3C电子产品的包装如纸盒及内装盒。因为用于3C电子产品的一般包装兼具一定结构强度以及包材外观呈现精美的图文印刷，这使得该3C电子产品的包装的材料中除了以废纸及天然植物纤维作为基本原料外，还需添加化学制品如荧光增白剂、湿强剂、消泡剂等，以及该包装的内外表面上需涂布一层以石油基聚合物构成的淋膜层或结合层，例如聚乙烯(Polyethylene,PE)及/或聚丙烯(Polypropylene,PP)等，以及该包装的外表面还印刷上一层化学油墨图文层，这些添加的化学制品皆不符现有环保要求。但不同的是，在本发明中，大体上是以天然植物纤维构成的所述纸浆材体66通过现有湿纤维纸塑工艺一体形成所述纸制容器14的所述纸制基材20的立体几何造型，同时用于大量生产如图1a 所绘的纸制容器14的所述纸制基材20，并涂布所述环保防水材料(如聚乳酸)于所述纸制基材20以形成用于防水的所述隔离层30。于本实施例中，通过该湿纤维纸塑工艺制成所述纸制容器14的所述纸制基材20包含蔗渣以及竹子纤维；于另一实施例中，通过该湿纤维纸塑工艺制成所述纸制容器14的所述纸制基材20，以重量百分比计，包含蔗渣100％wt；于另一实施例中，通过该湿纤维纸塑工艺制成所述纸制容器14的所述纸制基材20，包含蔗渣40％wt以及桉树纤维60％wt；于另一实施例中，通过该湿纤维纸塑工艺制成所述纸制容器14的所述纸制基材20，包含蔗渣40％wt以及美国南方松纤维60％wt。此外，于本实施例中，所述防水材料为聚乳酸(PLA)；但于其它实施例中，所述防水材料可为其它类型的生物可降解塑料，例如，包括但不限定，植物淀粉、聚己内酯(PCL)、聚乙烯醇(PVA)、聚丁二酸丁二醇酯(PBS)、硅胶(Silicone)的其中之一或数个结合。通过以上各环保材料，使得本发明的所述纸制容器14不仅成为符合美国食品和药物管理局(FDA)的食品级认证的食品接触材料，同时还能实现生物可降解性(Biodegradability)以及生物可堆肥性(Compostability)的环保要求。这里提到的『符合FDA食品级认证规范的食品接触材料』，例如，是包括但不限定，符合FDA认证检测项目U.S.FDA CFR 21 176.170的纸制品要求以及U.S.FDA CFR 21 175.300的聚合物涂层要求。这里提到的『生物可降解性(Biodegradability)以及生物可堆肥性(Compostability)的环保要求』是指符合，例如，包括但不限定美国的ASTM D6868、ASTM D5338-92、ASTM D6002-96以及ASTM D6400-99的其中之一或若干个生物降解与生物堆肥规范。
请参见图1a、1d以及图1e的示例，为了有利于所述纸制基材20能从如图7所绘的所述模具组件82、84中顺利的脱模，压制成型后的所述纸制基材20分别通过两个互为反向且分别对应所述模具组件82、84的脱模方向Y1、Y2进行脱模以分别形成所述纸制基材20的外内表面且所述脱模方向Y1、Y2是平行于所述环形杯壁24的一纵向的中心轴C1(本质上与图1a所绘载体1或纸制容器14的中心轴C1相同)，使所述环形杯壁24的外圆周面相对于所述脱模方向Y1形成一正拔模角θ1以及所述环形杯壁24的内圆周面相对于所述脱模方向Y2形成另一正拔模角θ1’，从而使所述纸制基材20的所述立体几何造型近似一个半圆锥体结构(如图1a所示)。在压制成型后，所述纸制容器14的所述纸制基材20通过所述脱模方向Y1脱模，使所述环形杯壁24还朝外侧向形成至少一突起部242(如图1a与图1e所示)。于本发明中，所述至少一突起部242的设计是用于确保每一所述纸制容器14在通过部件装配产线时(未绘示)能够依次逐个装配以形成每一对应的所述载体1(如图1b所绘)。于本实施例中，所述至少一突起部242包括若干个分离的侧凸块244，所述若干个分离的侧凸块244沿着所述环形杯壁24的外圆周面的 上半部等距分布；优选的，所述若干个分离的侧凸块244的数量为3个等距分布的侧凸块244(如图1a所绘)，如此能确保所述纸制容器14与另一所述纸制容器14上下叠合时受到位于两者间所述若干个分离的侧凸块244的卡止与限位(如图1f所绘)从而保持叠合后的所有所述纸制容器14皆能稳固不偏斜，特别是使每两个叠合后的所述纸制容器14的中心线C1皆能保持实质上的共线；惟，所述若干个分离的侧凸块244的数量不因此限定为三个，可以根据实际需要设计成不同的数量。
此外，在图1a、1d以及图1e绘示的本实施例中，每一所述侧凸块244的一最外表面2441是形成一均匀平坦面且所述最外表面2441从所述杯顶部22向下延伸一指定长度L1直至终止于一止挡端部2443。每一该侧凸块244的所述最外表面2441相对于所述脱模方向Y1是形成一正拔模角θ2，且所述环形杯壁24的所述外圆周面的正拔模角θ1与所述侧凸块244的所述最外表面的正拔模角θ2间的关系为：θ1>θ2≧0，如此避免了该侧凸块244的所述最外表面2441形成现有侧向拔模(Undercut)工艺的结构如产品的侧向凹面或凸面成型需要通过额外的斜向模具及/或横向模具，此种侧向凹面或凸面成型将相对于所述脱模方向Y1是形成一负拔模角。现有侧向拔模(Undercut)的设计会复杂化所述对应模具组件的构成以及其生产制程与时程，以致制造成本升高。但在其它实施例中，所述环形杯壁24的所述外圆周面的正拔模角θ1与所述侧凸块244的所述最外表面2441的正拔模角θ2间的关系，也可以设计成θ1≧θ2>0°。请进一步参见图1a、1c以及图1e的示例，于本实施例中，所述至少一突起部242还包括若干个相应所述侧凸块244所处位置的凹坑246，所述若干个凹坑246也是等距分布在所述环形杯壁24的所述内圆周面的上半部。每一所述凹坑246的下方还形成一向内延伸的座部2461以对应所述侧凸块244的所述止挡端部2443的位置。此外，每一所述若干个凹坑246相对于所述脱模方向Y2也是形成一正拔模角(未绘示)。于本实施例中，在通过涂布防水材料于所述纸制基材20从而形成所述隔离层30的过程中，所述隔离层30的侧边缘还形成若干个分别对应所述纸制基材20的所述凹坑246的凸面结构342。
当通过图7所绘的所述湿纤维纸塑工艺的所述一贯化自动化生产机台7大量生产出若干个所述纸制容器14之后，接下来所述若干个纸制容器14需通过部件装配产线(未绘示)以装配上各相关部件(如图1a所绘的过滤件12以及所述封盖10)从而完成所述载体1(如图1b所绘)的整体组装。为了方便运送所述若干个纸制容器14以及该部件装配产线的自动取件设备能从所述若干个纸制容器14中顺利取用每一个所述纸制容器14以装配上各相关部件，如图1f与1g所绘的所述若干个纸制容器14必须先以一个接一个的叠合方式排成一堆叠件，即一个所述纸制容器14的所述杯底部23由上而下从另一个 所述纸制容器14的所述杯顶部22的所述第一开口223中套入，以此类推从而组成一堆叠件6。这里提到该部件装配产线以及其自动取件设备皆为现有技术，如自动取件设备可以为电控的机械手臂或自动化进料设备，故其结构在此不予累述。为方便了解，虽然在图1f与1g的示例中，该堆叠件6仅包括两个叠合的所述纸制容器14；惟，不因此限定该堆叠件6中所述纸制容器14的叠合数量，本质上可根据需要的所述纸制容器14的数量作叠合。例如，在图1h与图1i的示例中，该堆叠件6包括了三个叠合的所述纸制容器14。
于图1f与1g的示例中，在两个所述纸制容器14上下叠合以形成所述堆叠件6的过程中，位于上方的所述纸制容器14的所述杯底部23是插入位于下方的所述纸制容器14的该杯顶部22的所述第一开口223中，接着通过上方的所述纸制容器14的所述至少一突起部242的每一所述侧凸块244位于(或被夹于)该两个上下叠合的所述纸制容器14间，使位于上方的所述纸制容器14的每一所述侧凸块244的该止挡端部2443止挡于下方的所述纸制容器14的该杯顶部22的所述环形表面221上以使该两个叠合的纸制容器14间的叠合深度限位在每一所述侧凸块244的所述指定长度L1，使每两个叠合的所述纸制容器14间保持一纵向限位间距H1(H1≧L1)，从而确保每一所述纸制容器14在通过所述部件装配产线的自动取件设备的取件时是从该堆叠件6的成排所述两个纸制容器14中依次逐个脱离(而不是这两个叠合的所述纸制容器14一起脱离)，以利于进行每一所述纸制容器14的各相关部件(如图1a所绘的过滤件12以及所述封盖10)的装配。于本实施例中，通过位于每两个叠合的所述纸制容器14间的所述至少一突起部242的每一所述侧凸块244的止挡与限位，能够确保每两个叠合的所述纸制容器14的中心轴C1共线，且所述限位间距H1所延伸的一方向平行于每一所述纸制容器14的中心轴C1，以提高该堆叠件6的所有纸制容器14间叠合的稳定性而不偏斜，能协助所述部件装配产线的自动取件设备精确地自叠合成排的所述纸制容器14中依次逐个取件。如图1h与图1i所绘，通过所述至少一突起部242的每一所述侧凸块244位于每两个叠合的所述纸制容器14间的止挡与限位，使该堆叠件6的成排的所述三个纸制容器14中每一叠合的深度与配合度大体上是一致的。如图1g与图1i所绘，于本实施例中，所述纵向的限位间距H1使每两个叠合的所述纸制容器14的所述环形杯壁24间形成一具有大于零值的最小横向间隙G1的间隙配合，所述间隙配合是取决于该大于零值的最小横向间隙G1的大小，用于确保每一所述纸制容器14通过所述部件装配产线的自动取件设备取件时是从叠合成排的所述若干个纸制容器14中依次逐个脱离，不因所述若干个纸制容器14间叠合的配合度过紧而导致多个所述若干个纸制容器14一起被取件而脱离，或因为叠 合的配合度过松而导致一部分所述纸制容器14尚未被取件即自行脱离或掉落。所述最小横向间隙G1的大小是受到所述环形杯壁24的一横向截面厚度W1以及每两个叠合的所述纸制容器14间的所述纵向限位间距H1的影响(如图1i所绘，每一所述纸制容器14的拔模角θ1皆相同)。于一实施例中，当所述环形杯壁24的所述横向截面厚度W1为0.6mm与所述纵向限位间距H1为8mm时，所述最小横向间隙G1为0.12mm，但不因此而限定所述最小横向间隙G1的大小；如在另一实施例中，当所述环形杯壁24的横向截面厚度W1为0.4mm与所述纵向限位间距H1为5mm时，所述最小横向间隙G1为0.09mm。根据实测发现，当所述纵向限位间距H1为一恒定值时，每两个叠合的所述纸制容器14的所述环形杯壁24间的所述最小横向间隙G1与所述环形杯壁24的所述横向截面厚度W1成反比；换句话说，当所述纵向限位间距H1为一恒定值且所述环形杯壁24的横向截面厚度W1越大时，每两个叠合的所述纸制容器14间的所述最小横向间隙G1越小。于另一实施例中，当每一所述纸制容器14的所述环形杯壁24的横向截面厚度W1为一恒定值时，每两个叠合的所述纸制容器14的所述环形杯壁24间的所述最小横向间隙G1与所述纵向限位间距H1成正比；换句话说，当每一所述纸制容器14的所述环形杯壁24的横向截面厚度W1为一恒定值且所述纵向限位间距H1越大时，每两个叠合的所述纸制容器14间的所述最小横向间隙G1越大。
请进一步参见图1a以及图1c的示例，所述载体1的所述过滤件12一体形成一垂直向的环形顶部120、一位于所述环形顶部120中央位置的第二开口122以及一完全封闭的凸弧底部123。于本实施例中，所述过滤件12的所述环形顶部120的侧边缘还形成若干个分别对应所述纸制容器14的所述凹坑246的该凸面结构142。当所述纸制容器14通过所述部件装配产线以进行所述过滤件12的装配时，所述过滤件12的所述垂直向环形顶部120的侧边缘围绕着所述纸制容器14的所述环形杯壁24的整个所述内圆周面并水密性地连接至所述环形杯壁24的所述内圆周面的上半部以将所述过滤件12装配于所述纸制容器14内部，亦即使所述过滤件12悬空吊挂于所述纸制容器14的所述环形杯壁24的所述内圆周面的上半部，从而使所述纸制容器14分隔成一第一承载空间126以及一第二承载空间128，并使该第二开口122向上对应所述纸制容器14的所述第一开口223所处位置，以及使所述过滤件12的该若干个凸面结构142分别对应伸入所述纸制容器14的所述若干个凹坑246内。于本实施例中，是通过超声波工艺热熔热塑性聚合物(如额外的粘接剂或各部件本身),例如聚乳酸(PLA)或硅橡胶(Silicone)或天然乳胶(Naturallatex)，将所述过滤件12的所述垂直向环形顶部120的侧边缘黏附到所述纸制容器14的所述环形杯壁24的内圆周面的上半部；惟不因此限定使用超声波工艺，亦可以使用 其它类型的现有粘贴工艺。所述第一承载空间126是限定在所述过滤件12的所述凸弧底部123的上表面至所述杯顶部22间以贮存相应所述饮料的介质3。所述第二承载空间128是限定在所述过滤件12的所述凸弧底部123的下表面至所述杯底部23间以贮存所述饮料介质3作用后所产生的所述饮料的流体；于一实施例中，每一所述纸制容器14内还贮存惰性气体(如氮气、二氧化碳等其中之一或混合)，以对所述饮料介质3进行保鲜。于本实施例中，所述饮料介质3包括但不限定，例如咖啡豆粉、茶叶、植物或水果干料、浓缩或萃取物质的其中之一。于本实施例中，所述过滤件12为一具有多孔网筛的纸制滤袋，且所述过滤件12为符合FDA食品级认证规范的食品接触材料，例如，包括但不限定，符合FDA食品级认证检测项目U.S.FDA CFR 21 176.170的纸制品，且也符合，包括但不限定于美国的ASTM D5338-92、ASTM D6002-96以及ASTM D6400-99的其中之一或若干个生物降解与生物堆肥规范。于另一实施例中，所述过滤件12是以聚酯纤维非织布(Non-woven fabric PET)制成，且符合，例如，包括但不限定于，美国FDA食品级认证检测项目U.S.FDA CFR 21 177.1630的PET制品。
请进一步参见图1a、1b以及图1c的示例，所述载体1的所述封盖10一体形成一顶面102、一底面104以及一位于所述封盖10的外圆周边的拉片106。在所述过滤件12已装配于所述纸制容器14内部之后，所述纸制容器14接着通过另一部件装配产线以进行所述封盖10的装配，所述封盖10的所述底面104进一步牢固性的粘贴于所述纸制容器14的所述杯顶部的整个所述环形表面221上，从而水密性封闭所述纸制容器14的所述第一开口223与所述第一承载空间126，从而将所述过滤件12与其内含的所述饮料介质3水密性封存于所述纸制容器14内,同时所述封盖10也水密性封闭所述过滤件12的所述第二开口122；于一实施例中，所述封盖10同时气密性封闭所述纸制容器14内所贮存的惰性气体(如氮气、二氧化碳等其中之一或混合)。于本实施例中，是通过超声波工艺热熔热塑性聚合物(如额外的粘接剂或各部件本身),例如聚乳酸(PLA)或硅橡胶(Silicone)或天然乳胶(Natural latex)，将所述封盖10的所述底面104以面对面的方式牢固性地粘贴于所述纸制容器14的所述杯顶部22的整个所述环形表面221上，且符合，例如，包括但不限定，FDA食品级认证检测项目U.S.FDA CFR 21 177.1210的食品容器的密封圈材料要求；惟，不因此限定使用超声波工艺，亦可以使用其它类型的现有粘贴工艺。于本实施例中，所述封盖10为一具有环保防水涂层(如聚乳酸层)的纸制品且为符合FDA食品级认证规范的食品接触材料，例如，包括但不限定，FDA食品级认证检测项目U.S.FDA CFR 21 176.170的纸制品要求以及U.S.FDA CFR 21 175.300的聚合物涂层要求，且也符合，包括但不限定于美国的ASTM D5338-92、ASTM D6002-96以及 ASTM D6400-99的其中之一或若干个生物降解与生物堆肥规范。于另一实施例中，所述封盖10是以铝箔片(Aluminum Foil)制成，且符合，例如，包括但不限定于，美国FDA食品级认证检测项目U.S.FDA CFR 21 175.300的有机涂层,金属和电镀制品要求以及U.S.FDA CFR 21 178.3910的金属制品的制造要求的其中之一或两者。
在一本发明的组合后的所述载体1(如图1b与图1c所绘)的实际应用示例中，当所述载体1装入一饮料冲制机(未绘示)内且所述饮料冲制机被启动后，所述饮料冲制机的一注入针管会以有限的长度向下刺穿所述载体1的所述封盖10直至延伸进入所述第一承载空间126中以及所述饮料冲制机的一排放针管同样以有限长度向上刺穿所述载体1的所述杯底部23直至延伸进入所述第二承载空间128中，接着通过所述注入针管注入液体(如温度在60℃以上的热水)与所述第一承载空间126内贮存的所述饮料介质3相互作用从而冲制成所述饮料的流体(如咖啡流体)，未溶解于所述液体中的饮料介质3以饮料渣体的形式存在。由于重力及/或气体压力的关系，所述饮料流体会通过位于该两承载空间126、128之间的所述过滤件12的过滤并从所述第一承载空间126逐渐流向所述第二承载空间128，这使所述饮料渣体遗留在所述过滤件12的所述第一承载空间126内，仅允许所述饮料流体逐渐滴漏(Dripped)至所述第二承载空间128内；接着，所述饮料流体通过位于所述第二承载空间128内的所述排放针管排放至一位于所述饮料冲制机之外的消费者的一饮料杯(如咖啡杯)中。于一实施例中，上述饮料冲制机可以是但不限定是库里格
