绝热套筒113是由绝热多孔非芳香族聚合物材料条82制成。绝热多孔非芳香族聚合物材料包括例如具有高熔融强度的聚丙烯基础树脂、聚丙烯共聚物和均聚物树脂中的一者或两者、以及一种或多种成孔剂。作为一个实例,成孔剂可以包括一级成核剂、二级成核剂以及由用于使这些树脂膨胀并且降低密度的气体装置(means)限定的发泡剂。在一个实例中,该气体装置包括二氧化碳。在另一个实例中,该基础树脂包括宽分布分子量聚丙烯,特征为单峰而非双峰的分布。特此参考2012年6月7日提交的并且名称为用于绝热容器的聚合物材料(POLYMERICMATERIALFORANINSULATIVECONTAINER)的美国申请号13/491,327中关于此类绝热多孔非芳香族聚合物材料的披露,该申请特此以其全文结合在此。
如图11-26中所示,根据本披露的绝热套筒在该套筒的内表面上可以任选地包括肋或肋区段、环圈、隆起物、小块或其他突出物,或凹槽、狭槽、通道、凹陷等的竖直的、水平的、螺旋的或其他的构型,而在杯子11的侧壁18与该绝热套筒之间形成气隙。此气隙形成了绝热屏障,以使从热饮料透过杯子11和/或该绝缘套筒向使用者的手的热传递(以及反过来,从使用者的手透过绝热套筒113和侧壁18向该饮料的热传递)最小化。如图4和5中所示,在示意性容器成形方法46、47中形成绝热容器110。
如图2和3中所示,绝热套筒113是在套筒成形方法46的过程中形成。直立围栏111具有第一厚度T1,并且第一和第二直立接片114、112各自具有第二厚度T2。如图1中所示,第二厚度T2大致为第一厚度T1的一半。因此,通过重叠和联接直立接片114、112而形成的桥114、112具有第三厚度T3,该第三厚度大致等于第一厚度T1。在一个示例性实施例中,该绝热套筒113可以在成形设备中形成并且与杯子11联接。绝热套筒113可以与一种自锁式模切特征一起来分别进行制造、储存、装运和/或出售。该自锁式特征可以具有不同形状来提升保持力。
使用例如图4中所示的套筒成形方法46制成绝热套筒113。如图4中所示,套筒成形方法46包括叠层卷装载步骤461A、压缩步骤462A、切割步骤463A、堆积套筒毛坯步骤464A、储存套筒毛坯步骤465A、装载套筒毛坯步骤461B、加热套筒毛坯步骤462B、卷绕套筒毛坯步骤463B、形成套筒步骤464B、堆积套筒步骤465B以及储存套筒堆叠的步骤466B。
叠层卷装载步骤461A将叠层卷86装载到切割机上,诸如模切机或金属对金属冲压机上。因此,将叠层薄片80拉进该切割机中进行加工。压缩步骤462A压缩该叠层薄片80的多个部分以形成压缩薄片。切割步骤463A切割该压缩薄片,以使套筒毛坯300从毛坯承载薄片80上切下。作为一个实例,可以将切割步骤463A与压缩步骤462A进行组合,而使得通常同时在同一件设备上进行这些步骤。堆积套筒毛坯步骤464A将套筒毛坯300堆积成套筒毛坯堆叠95。储存套筒毛坯步骤465A储存该套筒毛坯堆叠95,直到准备用于装载套筒毛坯步骤461B中为止。装载套筒毛坯步骤461B装载该套筒毛坯堆叠95,用于通过套筒成形机进行加工。加热套筒毛坯步骤462B向套筒毛坯300施加热量102。卷绕套筒毛坯步骤463B围绕套筒成形机中所包括的心轴来卷绕被加热的套筒毛坯300。形成套筒步骤464B通过用套筒成形机中所包括的主要夹子和辅助夹子来重叠和压缩直立接片112、114而形成桥112、114。堆积套筒步骤465B将套筒113堆积成套筒堆叠97。储存套筒堆叠步骤466B储存该套筒堆叠97用于随后的容器成形方法47中。
绝热容器110使用如图5中所示的容器成形方法47制成。如图5中所示,容器成形方法47包括装载杯子步骤471、装载套筒步骤472、将套筒定位于杯子上的步骤473、套筒联接步骤474以及检查步骤475。装载容器步骤471将容器堆叠124装载到容器成形机上。装载套筒步骤472将套筒堆叠97装载到该容器成形机上。将套筒定位于杯子上的步骤473将套筒113定位于杯子11上。套筒联接步骤474使用例如热量将套筒113联接于杯子11上,以建立绝热容器110。然而,套筒113可以通过粘合剂、摩擦配合或任何其他适合的替代方案进行联接。如图5中所示,检查步骤475检查绝热容器110的缺陷,随后将良好容器传到容器包装阶段48。
如图3A中所示,绝热套筒113是由薄片80制成。薄片80包括皮层81和绝热多孔聚合物材料条82。如图3A中所示,皮层81包括例如薄膜层811、油墨层812以及粘合剂层810。粘合剂层810被用于例如将皮层81叠层到条82上,以便将油墨层812夹在薄膜层811与粘合剂层810之间。
在套筒成形方法的另一个示例性实施例中,通过不将皮层81叠层到绝热多孔非芳香族聚合物材料条82上来修改该套筒成形方法46。因此,完全省略了该皮层,并且可以在绝热多孔非芳香族聚合物材料条82上直接进行印刷。
如图3中所示,杯子11的侧壁18在卷边16与底板20之间延伸。侧壁18包括本体12的联接于卷边16上的顶部22、和被安排成互连底板20与顶部22的底部24。顶部22被安排成在向下方向上向底板20延伸并且联接于底部24上,该底部被安排成在相反的向上方向上向卷边16延伸。顶部22与卷边16合作以形成口部32,如图1中所示,该口部被安排成开向内部区域14。
绝热套筒113被安排成围绕和包围热饮料子杯子11的外表面,以提供可以被顾客抓握的一个可抓握低温热屏障。绝热套筒113包括包含绝热多孔非芳香族聚合物材料的薄片80,该薄片被配置成提供使薄片80中能够发生局部塑性变形的装置,以提供位于薄片80的第一部分中的具有第一密度的、经过塑性变形的第一材料区段以及位于薄片80的一个邻近的第二部分中的具有低于该第一密度的第二密度的第二材料区段,而不使该绝热多孔非芳香族聚合物材料破裂,以便在薄片80中维持预定的绝热特征。
如图1和3中所示,薄片80被安排成围绕竖直中央轴线113A。薄片80包括直立内部接片114,该直立内部接片被安排成沿竖直中央轴线113A向上延伸并且与竖直中央轴线成间隔开的关系、并且被配置成提供具有该第一密度的该第一材料区段。薄片80还包括:直立外部接片112,该直立外部接片被安排成沿竖直中央轴线113A向上延伸并且与竖直中央轴线成间隔开的关系、并且与直立内部接片114沿其间的界面I匹配;和直立围栏111,该直立围栏被安排成互连该直立内部接片与该直立外部接片114、112并且围绕竖直中央轴线113A、并且被配置成提供具有该第二密度的该第二材料区段并且与直立内部和外部接片114、112合作以形成套筒形侧壁113。如图1和3中所示,围栏111具有实质上截头锥形形状。直立内部和外部接片114、112中的每一个具有弧形形状。
如图8′和8C中所示,直立内部接片114包括提供了与热饮料杯子11匹配的装置的一个内表面和面向直立外部接片112的外表面。直立外部接片112包括内表面,该内表面与直立内部接片114的该外表面匹配以在直立内部与外部接片114、112之间限定该界面I。直立外部接片112进一步包括背朝直立内部接片114的外表面。直立内部和外部接片114、112的内表面和外表面中的每一个在水平截面中具有弧形形状并且对着小于20°的锐角。直立围栏111在水平截面中为C形。直立内部和外部接片114、112中的每一个在水平截面中具有弧形形状。
直立围栏111包括直立左侧边缘111L和直立右侧边缘111R,该直立右侧边缘被安排成与直立左侧边缘111L成间隔开的面对面关系。直立外部接片112被配置成具有该第一密度并且与该直立内部接片匹配以建立桥,该桥被安排成互连该直立围栏的直立左与右侧边缘111L、111R并且是由具有该第一密度的经过塑性变形的材料形成。
直立围栏111具有面向竖直中央轴线113A的并且提供了用于与热饮料杯子11匹配的装置的内表面。直立围栏111还具有外表面,该外表面背朝内部区域14的中央竖直轴线113A并且围绕直立围栏111的内表面、并且与直立围栏111的该内表面合作而在其间限定第一厚度。
直立内部接片114包括面向竖直中央轴线113A并且提供了用于与热饮料杯子11匹配的装置的内表面、以及面向直立外部接片112的外表面。直立外部接片112包括内表面,该内表面面向竖直中央轴线113A并且与直立内部接片114的外表面匹配而在直立内部与外部接片114、112之间限定界面I。
直立外部接片112进一步包括背朝该直立内部接片114的外表面。如图8′中所示,直立内部接片114的内表面与外表面合作而在其间限定第二厚度,该第二厚度大致为该第一厚度的一半。如图8′中所示,直立外部接片112的内与外表面合作而限定第三厚度,该第三厚度大致为该第一厚度的一半。
图6-10中示出了根据本披露的绝热容器210的另一个实施例。如图6中所示,绝热容器210包括杯子11和绝热套筒213。如图6中所示,绝热套筒213类似于套筒113,但是绝热套筒213具有大致等于杯子高度D1的套筒高度H1。
作为一个实例,绝热套筒213在例如图4中所示的套筒成形方法46期间使用套筒毛坯300形成。毛坯300包括第一侧302和相反的第二侧(未显示)。毛坯300具有第一弧形边缘306,该边缘与以轴线310为中心的半径308相符。第二弧形边缘312与以轴线310为中心的半径314相符。第一线性边缘316与从该轴线310发出的第一射线相符,并且第二线性边缘318与从该轴线310发出的第二射线相符。如图6中所示,当卷绕该毛坯300而使得第一线性边缘316与第二线性边缘318重叠并置时,该绝热套筒213限定了截头锥形表面320。这些重叠的线性边缘316与318可以用多种方式中的任一种来固定,包括通过加热这些边缘316和318来结合该绝热多孔非芳香族聚合物材料所形成的机械连接。这些边缘316和318可以用粘合剂进行处理以将这些边缘316和318彼此固定。
如图11-13中所示,在由套筒毛坯322形成的绝热套筒313的又另一个实施例中,绝热套筒313在组装后的绝热套筒313的内表面326上包括多个通常水平的肋328。如图13中所示,套筒毛坯322被成形为具有第一厚度322T1,并且在一种套筒成形方法的压缩材料薄片步骤中,通过将该厚度减小到322T2形成多个凹陷324。在完成该压缩材料薄片步骤后,毛坯322包括形成了具有厚度322T2的凹陷324的多个局部塑性变形区域和不具有变形并且具有厚度322T1的多个肋328。如图11中概略地示出,凹陷324与肋328合作而在绝热套筒313的内表面326、杯子11的外表面102与一对邻近肋328A、328B之间形成气隙301。
毛坯322被成形为具有第一线性边缘330和第二线性边缘334。肋328被成形为在第一端处邻接第二线性边缘334并且与第一线性边缘330间隔开一个距离332,这样使得在该套筒成形方法的卷绕套筒毛坯步骤期间,当第一线性边缘330与第二线性边缘334重叠时,肋328的第一端与该第二端不重叠。这使得在该卷绕套筒毛坯步骤期间必须被压缩的材料量减少。肋328被定位成接合一个杯子(诸如杯子11)的外表面,而使得凹陷324的内表面326与该杯子的外表面间隔开从而提供气隙,而使得仅仅这些肋328接合该杯子的外表面。该气隙是绝热的,这样使得当使用者抓握绝热套筒313的外表面338时,阻碍了从该杯子向使用者的手的热传递。
如图14-16中所示,在由套筒毛坯422形成的绝热套筒413的再一个实施例中,绝热套筒413在组装后的绝热套筒413的内表面426上包括多个竖直肋428。如图16中所示,套筒毛坯422被成形为具有第一厚度422T1,并且在套筒成形方法的压缩材料薄片步骤中,通过将该厚度减小到422T2形成多个凹陷424。在完成该压缩材料薄片步骤后,毛坯422包括形成了具有厚度422T2的凹陷424的多个局部塑性变形区域和不具有变形并且具有厚度422T1的多个肋428。
毛坯422被成形为具有第一线性边缘430、第一弧形边缘440、第二线性边缘434以及第二弧形边缘442。肋428被成形为从第一弧形边缘440向第二弧形边缘442延伸。第一线性边缘430和第二线性边缘434各自沿着从公共轴线发出的射线安放,该公共轴线限定了第一弧形边缘440和第二弧形边缘442两者的曲率中心。每个肋428也沿着从该公共轴线444延伸的射线安放。肋428被定位成接合一个杯子(诸如杯子11)的外表面,而使得凹陷424的内表面426与该杯子的外表面间隔开从而提供气隙,而使得仅仅这些肋428接合该杯子的外表面。该气隙是绝热的,这样使得当使用者抓握绝热套筒413的外表面时,阻碍了从该杯子向使用者的手的热传递。
如图17-19中所示,在由一个套筒毛坯522形成的绝热套筒513的又另一个实施例中,绝热套筒513在组装后的绝热套筒513的内表面526上包括多个螺旋形肋528。如图19中所示,套筒毛坯522被挤出成具有第一厚度522T1,并且在套筒成形方法的压缩材料薄片步骤中,通过将该厚度减小到522T2形成多个凹陷524。在完成该压缩材料薄片步骤后,毛坯522包括形成了具有厚度522T2的凹陷524的多个局部塑性变形区域和不具有变形并且具有厚度522T1的多个肋528。
毛坯522被成形为具有第一线性边缘530、第一弧形边缘540、第二线性边缘534以及第二弧形边缘542。多个肋528被成形为沿着与第二线性边缘534垂直的多条轴线延伸。肋528延伸到邻接第二弧形边缘542或第一线性边缘530中的任一个。肋528被定位成接合一个杯子(诸如杯子11)的外表面,而使得凹陷524的内表面526与杯子的外表面间隔开以提供气隙,而使得仅仅这些肋528接合杯子11的外表面。该气隙是绝热的,这样使得当使用者抓握绝热套筒513的外表面时,阻碍了从该杯子向使用者的手的热传递。
如图20-22中所示,在由套筒毛坯622形成的绝热套筒613的另一个实施例中,绝热套筒613在组装后的绝热套筒613的内表面626上包括多个小块或突起628。如图22中所示,套筒毛坯622被挤出成具有第一厚度622T1,并且在套筒成形方法的压缩材料薄片步骤中在将毛坯622的其余部分减小到厚度622T2之后,留下了突起628。在完成该压缩材料薄片步骤后,毛坯622包括不具有变形并且具有厚度622T1的多个突起628。
毛坯622被成形为具有第一线性边缘630、第一弧形边缘640、第二线性边缘634以及第二弧形边缘642。突起628在多个行624中隔开,每个行624沿着与该第一弧形边缘640和第二弧形边缘642平行的弧来安放。突起628被定位成接合一个杯子(诸如杯子11)的外表面,而使得绝热套筒613的内表面626与该杯子的外表面间隔开从而提供气隙,而使得仅仅这些突起628接合该杯子的外表面。该气隙是绝热的,这样使得当使用者抓握绝热套筒613的外表面时,阻碍了从该杯子向使用者的手的热传递。
如图23-26中所示,在由套筒毛坯形成的绝热套筒713的又另一个实施例中,绝热套筒713在组装后的绝热套筒713的内表面736上包括多个通常水平的肋728。套筒毛坯722被挤出成具有第一厚度722T1,并且在套筒成形方法的移位材料薄片步骤中,通过使材料移位而形成多个肋728。在完成该移位材料薄片步骤后,毛坯722包括形成了具有厚度722T1的肋728的多个局部塑性变形区域,但该毛坯722的多个部分偏移而限定多个肋728。由于使该材料移位时的塑性变形和伸长,因此毛坯722的多个部分被减小到厚度722T2。
可以通过对毛坯722进行热成形的一种热成形方法进行该移位材料薄片步骤。因此,使厚度722T1和722T2最大化,这样使得绝热套筒713的绝热特性被最大化。
毛坯722被成形为具有第一线性边缘730和第二线性边缘734。肋728被成形成在第一端处邻接第二线性边缘734并且与第一线性边缘730间隔开一个距离732,这样使得在该套筒成形方法的卷绕套筒毛坯步骤期间,当第一线性边缘730与第二线性边缘734重叠时,肋728的第一端与该第二端不重叠。这使得在卷绕套筒毛坯方法期间必须被压缩的材料量减少。肋728被定位成接合一个杯子(诸如杯子11)的外表面,而使得凹陷724的内表面736与该杯子的外表面间隔开从而提供气隙,而使得仅仅这些肋728接合该杯子的外表面。该气隙是绝热的,这样使得当使用者抓握绝热套筒713的外表面738时,阻碍了从该杯子向使用者的手的热传递。
图27和28中示出了根据本披露的绝热套筒813的另一个实施例。如图27中所示,绝热套筒813包括直立套筒壁818和套筒底板820。套筒毛坯822被挤出成具有第一厚度,并且在套筒成形方法的压缩材料薄片步骤中,通过将材料压缩到相对更薄的第二厚度而形成折线828。如图27中所示,套筒底板820包括底板平台821和底板固持接片822,该底板固持接片在套筒成形期间被联接于套筒壁818上。在套筒成形后,套筒底板820与套筒壁818合作而在其间限定一个接收杯子的空间814。
图29-31中示出了根据本披露的绝热套筒913的再一个实施例。如图29-31中所示,绝热套筒913包括直立套筒壁918和套筒底板920。如图31中所示,套筒壁毛坯922和套筒底板毛坯924被挤出成具有第一厚度,并且在套筒成形方法的压缩材料薄片步骤中,通过在套筒底板毛坯924中将材料压缩到相对更薄的第二厚度而形成多条折线928。如图29中所示,套筒底板920包括底板平台921和四个底板固持接片922A、922B、922C、922D,这些底板固持接片在套筒成形期间被联接于套筒壁918上。在套筒成形后,套筒底板920与套筒壁918合作而在其间限定一个接收杯子的空间914。
在另一个实施例中,如图32中所示,绝热套筒1013具有总体上圆柱形的形状并且具有下部接片1002。该下部接片1002用于支撑圆柱形饮料器皿,如铝罐,例如当绝热套筒1013定位于该圆柱形饮料器皿上时。绝热套筒1013包括将该器皿定位于其中的开口,并且下部接片1002提供了阻挡,而使得该器皿被支撑在下部接片1002上以定位绝热套筒1013。绝热套筒1013与套筒213和113的不同之处在于,绝热套筒1013具有两个接缝1006和1008,材料在这里连结以形成该绝热套筒1013。
如图33中所示,用于绝热套筒1013的毛坯1022包括两个总体上矩形的部分1012、1014,它们通过下部接片1002互连。部分1012的第一线性边缘1016与部分1014的第一线性边缘1018匹配,并且这些边缘重叠并置而使得它们可以连结而形成接缝1006。类似地,部分1012的第二线性边缘1020同与之重叠且并置的部分1014的第二线性边缘1021匹配而形成接缝1008。这些接缝1006和1008是通过加热该材料并且定位这些边缘使得该绝热多孔非芳香族聚合物材料联接在一起而形成的。在其他实施例中,这些接缝可以通过向这些相应边缘涂覆粘合剂而形成。在任一方法中,都可以施加压力来辅助这种连结。在其他实施例中,可以通过沿一个边缘形成缝隙并且沿相对的边缘形成接片、并且将该接片插入该缝隙中并且保持于其中,来形成这些接缝。
在其他实施例中,举例来说,接缝1006和1008可以通过使用钩与环圈紧固系统(诸如)来紧固。该绝热多孔非芳香族聚合物材料具有足够的柔性,以允许该绝热套筒1013被形成为处于平坦状况下的毛坯并且可以由顾客来组装。类似地,在一些实施例中,套筒213和113可以使用钩与环圈紧固系统,使得这些套筒213和113可以作为平坦的毛坯被装运给顾客并且由顾客组装或在出售点进行组装。应了解的是,绝热套筒1013可以被成型为具有不同的表面不连续性,包括上文关于套筒313、413、513、613以及713所述的那些。
图34和35中示出了根据本披露的绝热套筒1113的另一个实施例。如图34和35中所示,绝热套筒1113包括直立内部接片1114、直立外部接片1112以及在内部与外部接片1114、1112之间延伸的直立围栏1111。直立内部接片1114被安排成从杯子11的底板20向上延伸。如图35中所示,直立外部接片1112被安排成从底板20向上延伸并且与直立内部接片1114沿其间的界面I匹配。直立围栏1111被安排成互连直立内部与外部接片1114、1112并且围绕接收杯子的空间1115。
绝热套筒1113的直立围栏1111在水平截面中呈C形,并且直立内部和外部接片1114、1112中的每一个在水平截面中具有弧形形状。直立围栏1111具有一个第一厚度11T1,并且第一和第二直立接片1114、1112各自具有第二厚度11T2。如图34中所示并且如图35中所示,第二厚度11T2大致等于第一厚度11T1。因此,通过重叠和联接直立接片1114、1112形成的桥1114、1112具有第三厚度11T3,该第三厚度大致等于第一和第二厚度11T1、11T2的两倍。
图36-40中示出了根据本披露的绝热套筒1213的另一个实施例。例如图36中所示,绝热套筒1213包括一个套筒壁1218和一个套筒壁固位件1220。如图36和38中所示,套筒壁1218包括第一套筒板1218A、与第一套筒板1218A间隔开的第二套筒板1218B以及连接腹板1218C,该连接腹板被定位成安放于第一与第二套筒板1218A、1218B之间并且互连该第一与第二套筒板。
如图36中所示,套筒壁固位件1220包括直立接片1220A、粘合剂层1220B以及离型衬里1220C。直立接片1220A被联接于第一套筒板1218A的与连接腹板1218C相对的自由端上。粘合剂层1220B被放置在直立接片1220A上,并且离型衬里1220C被放置在粘合剂层1220B上,以使粘合剂层1220B位于离型衬里1220C与直立接片1220之间,直到在现场组装绝热套筒1213。
在使用实例中,绝热套筒1213可以在现场被组装并且被联接于杯子11上。如图37中所示,绝热套筒1213呈与杯子11成间隔开的关系的拆分状态。如图38中所示,第二套筒板1218B绕连接腹板1218C背离第一套筒板1218A向后折叠,以暴露套筒固位件1220。如图39中所示,将离型衬里1220C从粘合剂层1220B上拉开,以暴露粘合剂层1220B。如图40中所示,直立接片1220A和粘合剂1220B被安排成与第二套筒板1218B的自由端重叠,形成绝热套筒1213。如图40中所示,杯子11被插入到绝热套筒1213中并且联接到绝热套筒上。作为一个实例,绝热套筒1213可以通过摩擦干扰或任何其他适合的方法联接到杯子11上。
用于制造这些绝热套筒213和113和这些套筒的变体的该绝热多孔非芳香族聚合物材料是稍微柔性的并且在负载下能够略微扩张,以允许适当尺寸的套筒以某个偏斜水平抓握器皿。
具有不同图案的绝热套筒813、913、1013、1113以及1213(包括上文关于套筒313、413、513、613以及713所述的那些),是位于本披露的范围之内的。可以通过在各个绝热套筒中形成塑性变形局部区域来形成这些不同图案。举例而言,可以通过压缩该套筒的多个部分使得该由未被压缩部分制成图案,来形成这些图案。作为另一个实例,可以通过压缩该套筒的多个部分使得由被压缩的部分制成图案,来形成这些图案。在再一个实例中,这些图案可以通过使该套筒的多个部分变形来形成,以使整个该套筒的厚度最大化。在又另一个实例中,可以使用变形与压缩的组合。
如上文所述的该绝热套筒向杯子提供了强度和绝热性。具有本披露的绝热套筒的热成形杯子的一个特征在于,该热成形杯子是无接缝的,该绝热套筒又提供所希望的强度、绝热性以及一个可印刷表面。该热成形杯子具有无接缝的边缘,由此提供盖子密封件,这与膨胀聚丙烯杯子(有接缝)相比减少了可能的泄漏。本披露的该热成形杯子和绝热套筒的另一个特征在于,达到了所希望的强度和绝热水平,但杯子侧壁具有具有所希望的抗刺穿水平。本披露还提供了可以与杯子分开地提供的绝热套筒。
如本披露所述的由绝热多孔非芳香族聚合物材料制成的绝热套筒还可以用于或适配成用于除容器之外的结构。作为一个实例,该绝热多孔非芳香族聚合物材料可以被用作但不限于窗台密封件、管道包布或需要具有良好绝热性的低密度、轻重量、薄的材料的其他应用。
在替代性的示例性实施例中,杯子、基部或本体可以用除热成形材料之外的材料制成。作为实例,该杯子、基部或本体可以用一种注塑模制的材料或任何其他适合的替代材料制成。
