发明背景
饮料容器(比如饮料杯)用来容纳各种饮料，包括冷饮(比如苏打水和冰茶)和热饮(比如咖啡和茶)。冷饮通常加冰，并且由于环境空气中的湿度，导致在饮料容器的外表面上形成水滴(即，冷凝物)。这种冷凝物抑制使用者安全地紧握饮料容器的能力，这样可导致意外溢出，特别是在操作机动车辆的同时喝饮料时。此外，在饮料容器的外表面上形成冷凝物可导致不期望的在支撑饮料容器的表面上形成一滩冷凝物，从而可能损害表面。
因此，本领域技术人员在饮料容器领域持续创新。

由以下说明、附图和所附权利要求，所公开的基于纸板的饮料容器的其他方面将变得显而易见。

发明详述
参考图1，所公开的基于纸板的饮料容器的一方面(总的指定为10)可形成为杯，比如12盎司、16盎司、21盎司或24盎司一次性外卖杯。饮料容器10可包括具有上端部分14和下端部分16的截头圆锥侧壁12和与下端部分16连接的底壁18，以限定饮料容器10内的内体积20。侧壁12的上端部分14可限定进入内体积20的开口22。任选地，侧壁12的上端部分14可另外包括唇缘23，用于使盖子(未示出)等固定于饮料容器10。
本领域技术人员认识到，所公开的饮料容器10可以各种形状和尺寸形成，并且在不脱离本公开的范围的情况下，可形成具有比如上讨论的侧壁12和底壁18更少或更多的壁。
如图2所示，侧壁12可形成为具有第一层24、第二层26和粘合剂层28的层状结构。第一层24可包括内侧表面(inner surface)30和外侧表面(outer surface)32，其中第一层24的内侧表面30可限定(或可接近)饮料容器10的内部表面(interior surface)34。第二层26可包括内侧表面36和外侧表面38，其中第二层26的外侧表面38可限定饮料容器10的外表面40。
在一方面，粘合剂层28可放置在第一层24和第二层26之间，使得粘合剂层28与第一层24的外侧表面32和第二层26的内侧表面36两者连接。在另一方面，任选的另外的层(未示出)可放置在第一层24和粘合剂层28之间，使得粘合剂层28可与第二层26的内侧表面36和任选的另外的层之一的外侧表面(未示出)连接。
如图3所示，在一个任选的方面，第一层24的内侧表面30可涂有水分阻挡层42，从而当饮料容器10的内体积20填充饮料(未示出)时，使得饮料容器10的侧壁12的内部表面34耐水分渗透。例如，水分阻挡层42可为(或可包括)一层经层叠、挤出涂布或与第一层24的内侧表面30连接(例如，粘合剂)的聚乙烯。可用于水分阻挡层42的其他水分阻挡材料为本领域已知的和市售可得的。
第一层24可为能成型为侧壁12的材料片。第一层24可具有足以使饮料容器10具有足够的结构完整性，以在内体积20中容纳饮料时保持饮料容器10的期望的形状的厚度T1和刚性。例如，第一层24可由可再循环的材料(比如纸板)或聚合材料(比如聚碳酸酯或聚对苯二甲酸乙二酯)形成，并且可具有至少约6点(point)的厚度，比如约8至约24点。
第二层26可由纸板片形成，该纸板片可经漂白或未经漂白，并且基重可为至少约85磅/3000平方英尺，并且厚度T2为至少约6点。例如，第二层26可由纸板(比如衬板或固体漂白的硫酸盐(SBS))形成，基重范围为约180至约270磅/3000平方英尺，并且厚度T2范围为约8-36点。
在这一点上，本领域技术人员认识到，除了纤维素纤维以外，用于形成第二层26的纸板可包括各种组分和任选的添加剂。例如，第二层26可任选包括以下一种或多种：粘合剂、填料、有机颜料、无机颜料、空心塑料颜料、可膨胀的微球体和膨胀剂(比如化学膨胀剂)。
在一个任选的方面，用于形成第二层26的纸板可包括分散于其中的磨木浆(ground wood)颗粒。不希望束缚于任何具体的理论，我们认为，在第二层26中的磨木浆颗粒促进在外表面40上形成的冷凝物吸收至第二层26和粘合剂层28中。
在另一任选的方面，可将第二层26的外侧表面38纹理化，以改进饮料容器10的外表面40的紧握能力以及容器10的水分吸收性质。用于使外侧表面38纹理化的一种技术包括将外侧表面38压纹。虽然技术人员可领会各种纹理图案，但是有用的纹理/压纹图案的实例包括方格图案、连续的水平线、连续的垂直线以及相对于饮料容器10的垂直轴以非直角布置的连续的线。
因此，本领域技术人员认识到，在不脱离本公开的范围的情况下，容器10的外表面40可具有各种特征、形状、轮廓和结构。
第二层26可设计成使在侧壁12的外表面40上形成的水分(即，冷凝物)转移至侧壁12的第二层26和粘合剂层28中最大化。例如，可将第二层26的内侧表面36和外侧表面38两者的表面上胶(surfacesizing)和孔隙率设计成使水分(即，冷凝物)吸收最大化和使冷凝物形成的不利影响最小化。
在一个具体的方面，可控制第二层26的内侧表面36和外侧表面38的表面上胶，使得内侧表面36的赫力仕(Hercules)上胶小于外侧表面38的赫力仕上胶。例如，可控制第二层26的内侧表面36和外侧表面38的表面上胶，使得内侧表面36的上胶范围为约30至约80赫力仕单位，而外侧表面38的上胶范围为约100至约150赫力仕单位。
在另一个具体的方面，可控制第二层26的内侧表面36和外侧表面38的孔隙率，使得内侧表面36的格利(Gurley)孔隙率小于外侧表面38的格利孔隙率(即，内侧表面36上更大的孔体积，和外侧表面38上的孔体积)。例如，可控制第二层26的内侧表面36和外侧表面38的孔隙率，使得内侧表面36的孔隙率为约20格利单位(400cc试验)，而外侧表面38的孔隙率为约40格利单位(400cc试验)。
在这一点上，本领域技术人员认识到，可使用各种上胶剂来控制表面上胶，比如烷基乙烯酮二聚物。此外，本领域技术人员认识到，通过改变纸板制造工艺(比如改变形成、压紧和干燥织物的选择)可实现与水分吸收有关的其他性质(比如孔隙率)。
因此，通过改变第二层26的内侧表面36和外侧表面38两者的表面上胶和孔隙率，可控制水分吸收速率。例如，可实现在外侧表面38的水分吸收速率为0.02-0.1g/cm2/分钟，而在内侧表面36为0.03-0.2g/cm2/分钟。
如上所述，可将第二层26的外侧表面38压纹，从而提供用于冷凝物吸收的另外的表面积。例如，可将压纹表面的表面形态设置成使得与压纹表面的手指接触的面积为容器10在手指下的总表面的20％。可设计压纹凹槽的形状，使得压纹结构的尖部(pick)上的孔隙率比压纹结构的凹部大30％。由于在压纹结构的峰区域中的设计的应力浓度，可产生增大的孔隙率，同时尖部的较大的曲率导致尖部区域的较低的孔隙率。
粘合剂层28可为一层隔热材料，其将第二层26与下衬层(例如，第一层24)连接。粘合剂层26的厚度TA范围可为约0.05毫米至约5毫米。当然，本领域技术人员认识到，当期望更大的隔热时，可使用更大的厚度TA。
如果粘合剂层28的每单位厚度的隔热R-值大于第二层26的每单位厚度的隔热R-值，则可认为粘合剂层28是隔热的。例如，粘合剂层28的每单位厚度的隔热R-值与第二层26的每单位厚度的隔热R-值的比率可为至少约1.25∶1，比如1.5∶1、2∶1乃至3∶1。
粘合剂层28可覆盖第二层26的内侧表面36的全部或仅一部分。作为一个实例，粘合剂层28可覆盖第二层26的内侧表面36的表面积的约20至约100％。作为另一个实例，粘合剂层28可覆盖第二层26的内侧表面36的表面积的约20至约80％。作为再一个实例，粘合剂层28可覆盖第二层26的内侧表面36的表面积的约40至约60％。作为再一个实例，粘合剂层28可覆盖第二层26的内侧表面36的表面积的约50％。
当粘合剂层28覆盖小于第二层26的全部内侧表面36时，可随意或以各种图案将粘合剂层28施用于内侧表面36。本领域技术人员认识到，某些图案，比如垂直的条(直的或波浪形的)，可增大饮料容器10的整体结构完整性。
在一方面，粘合剂层28可形成为包括有机粘合剂和填料的复合材料。有机粘合剂可包含粘合剂层28的15-70％重量，而填料可包含粘合剂层28的2-70％重量。
复合粘合剂层28的有机粘合剂可为能将第二层26与下衬层(例如，第一层24)结合的任何材料、混合物或分散体。有机粘合剂也可具有隔热性质。合适的有机粘合剂的实例包括胶乳(比如苯乙烯-丁二烯胶乳和丙烯酸类胶乳)、淀粉(比如未凝胶化的淀粉)、聚乙烯醇、聚乙酸乙烯酯以及它们的混合物和组合。
复合粘合剂层28的填料可为有机填料、无机填料或有机填料和无机填料的组合。有机填料包括硬有机填料和软有机填料。合适的硬有机填料的实例包括锯屑和磨木浆。合适的软有机填料的实例包括纤维素浆、颗粒状淀粉(pearl starch)、合成纤维(例如，人造丝纤维)、玉米淀粉渣(gluten feed)、玉米种子外壳和洋麻核(植物材料)。合适的无机填料的实例包括碳酸钙、粘土、珍珠岩、陶瓷颗粒、石膏和灰泥。例如，有机填料可包含复合粘合剂层28的2-70％重量，而无机填料可包含复合粘合剂层28的0-30％重量。
所有的或一部分填料可具有相对高的粒径(例如，500微米或更大)。使用高粒径填料材料可增加粘合剂层28的厚度TA，从而充当间隔物，其改进粘合剂层28的隔热性质。例如，粘合剂层28可形成为平均粒径为至少500微米(比如约1000至约2000微米)的包括有机粘合剂和硬有机填料(比如锯屑)的复合材料。
在一个具体的方面，粘合剂层28可为泡沫。泡沫可通过在施用前将粘合剂层28的各组分机械搅动起泡(whip)而形成。任选地，泡沫形成剂可包含在粘合剂层制剂中，以促进泡沫形成。作为一个实例，粘合剂层28的10-60％的泡沫可为开口空隙，从而促进从饮料容器10的外表面40吸收水分。作为另一个实例，粘合剂层28的10-30％的泡沫可为开口空隙。
在另一个具体的方面，粘合剂层28可由本文所述的粘合剂-填料制剂形成，其中该制剂的假塑性指数范围为0.3-0.5。这样的范围提供具有足够最小化厚度TA的粘合剂层28，同时保持施用低粘度下的制剂的能力。例如，制剂可具有2,000-50,000厘泊范围的低剪切粘度和100-5,000厘泊范围的高剪切粘度。
作为一种选项，粘合剂层28可另外包括增塑剂。增塑剂可包含复合粘合剂层28的0.5-10％重量。合适的增塑剂的实例包括山梨糖醇、Emtal乳化脂肪酸和甘油。
作为另一选项，粘合剂层28可另外包括硅酸钠，其可充当填料，但是我们认为，通过在干燥过程期间快速增大粘合剂的粘度，它有助于粘合剂的粘合和固化。硅酸钠可包含粘合剂层28的0-15％重量，比如粘合剂层28的约1至约5％重量。
本领域技术人员认识到，在初始处理后，粘合剂层28可保持约10-15％重量的平衡水分含量。
在这一点上，本领域技术人员认识到，可将形成粘合剂层的材料配制成可生物降解的。
实施例
实施例1-4
制备适于形成粘合剂层28的4个样品复合粘合剂材料(No.1-4)。制剂提供于表1。
表1
Figure BPA00001462275300091
Figure BPA00001462275300101
将制剂No.1-4机械搅动起泡，以形成假塑性指数范围为约0.3至约0.5的泡沫。
用于形成粘合剂层28的另外的制剂以及适于形成侧壁12的方法公开于2009年5月5日提交的美国专利序列号61/175,569，其整个内容通过引用结合到本文中。
实施例5
构造具有侧壁和底壁的21盎司饮料杯。使用粘合剂制剂No.1(上述实施例1)如上所述制备侧壁，所述粘合剂制剂No.1夹在基重为180磅/3000平方英尺并且厚度为16点的SBS纸板的第一内侧层与基重为150磅/3000平方英尺并且厚度为14点的SBS纸板的第二外侧层之间。粘合剂制剂覆盖第二层的约100％的内侧表面，并产生厚度为约0.5毫米的粘合剂层。第一层的内侧表面涂有一层1密耳聚乙烯。杯的外表面的表面积为300平方厘米。
将该杯放置在保持在约73℉的环境温度和约50％相对湿度的受控的气氛中。当杯在受控的气氛中时，将15.75盎司冰水混合物加入到杯中，并启动计时器。在2小时内，每20分钟，使用新的吸水布将聚集的表面冷凝物从杯的外表面擦掉，并测定在布上收集的冷凝物的质量(即，擦拭后布的质量减去擦拭前布的质量)。结果绘制于图4作为“实施例5”数据点，其中每个数据点代表在20分钟期间收集的表面冷凝物的量。
本文使用的“表面冷凝物”是指在容器的外表面上形成的冷凝物，能将它从容器的外表面擦掉。表面冷凝物通常不包括在容器的外表面上或之内形成的冷凝物，以及以防止或抑制人擦掉冷凝物的能力的方式被容器吸收的冷凝物。然而，应理解的是，虽然从外表面擦掉表面冷凝物，但是例如由于毛细作用，还可收集某些可忽略量的内冷凝物。
为了比较，还对清澈(clear)的聚对苯二甲酸乙二酯塑料杯(“Clear”)；在两侧涂有聚乙烯的单层纸板杯(“对照”)；得自GeorgiaPacific的由聚合泡沫制备的PERFECT TOUCH牌杯(“Perfect touch”)；得自加州Veralis的Insulair，Inc.的INSULAIR牌杯(“Insulair”)；和由SYTROFOAM形成的杯(“Styrofoam”)进行相同的冷凝物形成测试。所有的比较杯的外表面积也为约300平方厘米。比较结果也绘制于图4。
实施例6
按照实施例5的上述方式构造和测试21盎司饮料杯，不同之处在于杯的外表面用方格图案压纹。结果绘制于图5作为“实施例6”数据点，连同图4所示相同的比较结果。
实施例7
按照和实施例5有关的上述方式构造和测试21盎司饮料杯，不同之处在于第二外侧层包含粒径范围为约100至约1000微米的磨木浆颗粒，从而产生基重为约180磅/3000平方英尺的板。测试结果绘制于图6作为“实施例7”数据点，连同图4和5所示相同的比较结果。
实施例8
在引入冰水混合物之前和具有冰水混合物2小时后即刻两者，测试实施例6的21盎司饮料杯的压缩强度。使用得自伊利诺伊州Glenview的Illinois Tool Works，Inc.的INSTRON牌压缩测试机器，以水平结构(即，垂直于杯的垂直轴)在杯5％形变时测量压缩力。结果提供于表2并在图7(“实施例8”数据点)与具有冰水混合物2小时后的总冷凝物形成绘制。
表2
为了比较，对在实施例5-7中用于比较的Perfect Touch、Insulair和对照杯，以及由伊利诺伊州Chicago的Solo Cup Company以SOLO商标出售的大的两层杯(“Solo Two Ply”)进行相同的压缩强度测试。比较测试的结果也提供于图7。
因此，与SYTROFOAM杯类似，根据本公开形成的饮料容器表现出意外的低表面冷凝物形成，但可生物降解，这与SYTROFOAM杯不同。此外，根据本公开形成的饮料容器保持显著高的压缩力(例如，大于2.5磅)，甚至在装有冷饮2小时后。
虽然已显示和描述了所公开的基于纸板的饮料容器的多个方面，但是在阅读说明书后本领域技术人员可想到修改。本申请包括这些修改并且仅受权利要求范围的限制。
