Description

能快速成型的个性化鞋垫及其制造方法 技术领域
本发明关于鞋垫结构，尤其指一种能根据个人的脚底立体构形而快速成型，且其内设有负压辅助组件的个性化鞋垫。
背景技术
人们在穿鞋时，鞋内都会放置鞋垫，以通过鞋垫的吸震与缓冲效果，减缓因长时间站立或行走而引起的脚底疼痛与其它病症，同时还能给予足部较佳的舒适感。一般来说，正常情况下，脚底应会具有明显较高的足弓(即，脚内侧呈凹弧状的部分)，且距骨(talus)与跟骨(calcaneus)应在同一直线，并垂直于地面。但是，随着先天或后天关系，每个人的足底的立体构形都会有所差异，例如，部分先天为扁平足(Flat Foot)的人，其足弓会较低甚至没有足弓；或者，当幼儿过早站立或是长期姿势不正确时，容易造成外翻足(Pronation of the foot)的情况。
目前的鞋垫在生产上，通常是以同样的造型大量生产，而非针对每个人的脚底情况，因此，使用者在选购鞋垫上，往往会挑选较软的鞋垫，如此，当使用者踩踏前述鞋垫时，该鞋垫会因具有较大的变形量，而给人较为舒适的感觉。然而，较软的鞋垫其支撑性往往较为不足，因此，在长时间使用下，反而容易造成足底肌肉异常紧绷，且对于原先具有扁平足或高足弓的人来说，将更容易加剧其下肢筋膜不好的状况。由此可知，在挑选鞋垫上，仍应选择对于脚底有支撑力的鞋垫较佳。
诚如前述，由于每个人的足底立体构形存有差异，因此大量生产的鞋垫显然无法满足每个人的需求，但是，目前客制化量身订作的鞋垫通常是作为矫正用途，其制作时间不仅需要数周之久，且所费不赀，尤其是制作过程繁琐，还需诸多专门设备与工具，因此，对于一般大众而言，显然较不实际。有鉴于此，发明人曾设计出一种能快速量身打造的矫正鞋垫，兹简单说明如后，请参阅图1A所示，该矫正鞋垫10包括一内包覆层11、多个颗粒12及一外包覆层13，其中，该内包覆层11本身为透气材料，且其内填装有该等颗粒12，之后，该内包覆层11连同该等颗粒12能一并被置 入不透气的外包覆层13中，又，该外包覆层13上设有一空气通道131，该空气通道131连通该外包覆层13的内外。
请再参阅图1A所示，在制作上，该矫正鞋垫10能先被放置于一支撑治具15(如：鞋模台)的定形凹槽151中，之后，专业人员(如：复健师)能够协助用户调整足部位置，令该足部能以正确姿势(即，符合矫正所需的姿势)踩踏至该矫正鞋垫10的顶面，同时，该等颗粒12也会被塑形(成形)成预期的矫正状态；在完成前述塑形过程后，专业人员能够以专门的抽真空设备(如：真空泵、阀门、真空计、管件、接头…等)连接该空气通道，并对该矫正鞋垫10执行抽真空作业，令该等颗粒12定形在相互紧密贴靠且无法继续位移的状态后，再将该空气通道131气密封合，即定形出该矫正鞋垫10(如图1B所示)。
虽然发明人所构思的前述矫正鞋垫10相较于熟知的矫正鞋垫而言，其个性化制作时间极短(小于10分钟)，且价格也远较低，但仍不足以使一般民众广为使用，主要原因在于，该矫正鞋垫10不仅需要专门的抽真空与塑形辅助设备(如：鞋模台、震荡台、封口机…等)，同时还需要专业人员协助，这是一般使用者自己所不能提供，故有需要的使用者仅能特别去少数的专门场所购置，例如，足部矫正所或鞋垫专卖店等。此外，为了使该矫正鞋垫10具有良好的矫正能力，其内需要放置大量的颗粒12，才能够塑形出符合矫正所需的状态，此种情况，也造成该矫正鞋垫10的整体生产费用仍高于一般鞋垫。
对于一般民众而言，其所使用的鞋垫实际上并不一定需要严苛到矫正性质，而是以舒适、日常保健为主，因此，在前述问题(如：需要专门的设备、专卖店/场所、专业人员服务与较高费用)之下，该矫正鞋垫10将会大幅降低一般民众的购买与使用意愿，故，如何有效解决前述问题，以提供一般民众更适合的产品，即成为本发明的一重要课题。
发明内容
有鉴于熟知的鞋垫仍有诸多缺点，因此，发明人凭借着多年的实务经验，并在多次的研究、尝试与实作后，终于设计出本发明的一种能快速成型的个性化鞋垫及其制造方法，期能有效解决前述问题。
本发明的一目的，提供一种能快速成型的个性化鞋垫，其能被置放入一鞋子内或成为该鞋子的一部分结构，供用户的脚掌踩踏其上，该个性化鞋垫包括一外包覆层、多个颗粒、至少一启闭组件与至少一负压辅助组件，其中，该外包覆层由不透气结构所制成，该外包覆层的平面构形能与脚掌的整体或局部的平面构形相匹配，其设有一空气通道，该空气通道能连通该外包覆层的内外，该外包覆层的顶面，至少有局部区域由具弹性或挠性的不透气材料或结构所制成；该启闭组件能使该空气通道呈单向往外排气状态，或者能使该空气通道转换于呈双向导通状态与呈双向不导通状态；该等颗粒能直接或间接被填装至该外包覆层内，令该外包覆层呈现一预定厚度，且该等颗粒能在该外包覆层之内移动；各该负压辅助组件位于该外包覆层内，其内设有至少一个容气空间，在其处于外力压迫的状态下，其内的空气会被排出，又，当外力移除后，其自身的恢复力也会迫使其吸取外部空气；在脚掌的整体或局部踩踏在该外包覆层上的情形下，该等颗粒能随着脚掌的整体或局部的立体构形作位移而完成塑形(即，成形)，且该外包覆层内的空气会因脚掌整体或局部施加的压力，经由该空气通道，排出至该外包覆层之外，该负压辅助组件亦会受到前述压力影响而缩小其占用容积，其内的空气也会经由该空气通道而排出至该外包覆层之外，再将该空气通道气密封合的情况下，移除脚掌所施加的压力，该负压辅助组件会因自身的恢复力而扩张，并吸收该等颗粒间的残留空气而产生负压，使得该等颗粒因而定形在相互紧密贴靠且不易位移的状态，以得出该个性化鞋垫，如此，使用者不需额外使用任何专门设备，便能够轻易且迅速地完成符合自身脚底立体构形的个性化鞋垫。
本发明的另一目的，提供一种能快速成型的个性化鞋垫的制造方法，其中，该个性化鞋垫能被置放入一鞋子内，供使用者的脚掌踩踏其上，该制造方法首先会执行一填装作业，以能依据该个性化鞋垫的设计，将至少一启闭组件与至少一负压辅助组件设置于一外包覆层的预定位置上，并将多个颗粒填装至该外包覆层内，以使该外包覆层呈现一预定厚度，且该等颗粒能在该外包覆层之内移动，前述安置及填装工作完成后，即气密封闭该填装口，以完成填装作业；其中，该外包覆层为不透气结构，其平面构形能与脚掌的整体或局部的平面构形相匹配，且其设有一空气通道，该空 气通道能连通该外包覆层的内外；该启闭组件能使该空气通道呈单向往外排气状态，或者能使该空气通道转换于呈双向导通状态与呈双向不导通状态；该负压辅助组件内设有至少一个容气空间，在其处于外力压迫的状态下，其内的空气会被排出，又，当外力移除后，其自身的恢复力亦会迫使其吸取外部空气；之后，执行一成形作业，在脚掌的整体或局部踩踏在该外包覆层上的状态下，能使该等颗粒随着脚掌的整体或局部的立体构形作位移而完成塑形(即，成形)，且该外包覆层内的空气会因脚掌整体或局部施加的压力，经由该空气通道，排出至该外包覆层之外，该负压辅助组件亦会受到前述压力影响而缩小其占用容积，其内的空气也会经由该空气通道而排出至该外包覆层之外；又，执行一定形作业，将该空气通道封闭住，以使该外包覆层之外的空气无法流入该外包覆层内，且在移除脚掌所施加的压力的情况下，该负压辅助组件会因自身的恢复力而扩张，并吸收该等颗粒间的残留空气而产生负压，使得该等颗粒因而定形在相互紧密贴靠且不易位移的状态，以得出该个性化鞋垫。
本发明的鞋垫具有重大突破，使用者不需自行准备任何专业器具，自身即可以简单、快速的制备出其个性化鞋垫，意即，具有在便利商店或网购方式售卖的条件，本发明的鞋垫具有下列优点：
(1)本发明的鞋垫的个性化成型极为简单，且不需其它的工具，因此，使用者能够自行操作，并能迅速地完成自身所需的个性化鞋垫；
(2)使用者能够方便取得鞋垫，例如，能在便利商店或以网购等方式取得；
(3)价格便宜；
(4)由于该鞋垫的立体构形是适应使用者的个人足形，故穿戴上极为舒适；
(5)本发明的鞋垫在进行加热固形的程序之前，能够依使用者需要将大气引入外包覆层内，以重新制作该鞋垫的立体构形，直到满意为止；及
(6)对于日常保健而言，本发明的鞋垫效果良好。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚明白，以下结合具体实施方式，并参照附图，对本发明所公开有关“能快速成型的个性化鞋垫及其制造方法”的实施方式进一步详细说明。本领域技术人员可由本说明书所公开的内容了解本发明的优点与效果。本发明可通过其他不同的具体实施例加以施行或应用，本说明书中的各项细节也可基于不同观点与应用，在不悖离本发明的构思下进行各种修改与变更。另外事先声明，本发明的附图仅为简单示意说明，并非依实际尺寸的描绘。此外，除非上下文有明确指出或定义，否则本发明的“一”、“该”的含义包括多个。又，以下的实施方式将进一步详细说明本发明的相关技术内容，但所公开的内容并非用以限制本发明的保护范围。
应理解，虽然本文中可能使用术语第一、第二等来描述各种组件或者 信号，但这些组件不应受这些术语的限制。这些术语主要是用以区分一组件与另一组件。另外实施例中提到的方向用语，例如“上”、“下”、“前”、“后”、“左”、“右”等，仅是参考附图的方向。因此，使用的方向用语是用来说明并非用来限制本发明的保护范围。此外，本文中所使用的术语“或”，应视实际情况可能包括相关联的列出项目中的任一个或者多个的组合。
本发明一种能快速成型的个性化鞋垫及其制造方法，该个性化鞋垫最主要的用途，是作为一般适应性、舒压式的鞋垫使用，其不需额外使用特殊的辅助工具(如：专门的抽真空设备等)，且使用者本身就能够轻易地制作出匹配于自身脚底立体构形的个性化鞋垫，但是，本发明的个性化鞋垫并不排除作为矫正用途。请参阅图2所示，在一第一实施例中，该个性化鞋垫2包括一外包覆层21、多个颗粒22、至少一负压辅助组件23与至少一启闭组件24，其中，该外包覆层21为不透气材料或不透气结构，其周缘被气密封合，以在其内形成一第一容纳空间，又，该外包覆层21的平面构形能与脚掌的整体的平面构形相匹配(如图3A所示)，且其顶面至少有局部区域由具弹性或挠性的不透气材料或结构所制成，以能在后续说明的制程中，形成符合脚掌的平面构形，但不以此为限，在本发明的其它实施例中，该外包覆层21的平面构形亦能够与脚掌的局部(如：对应于趾骨、中足骨或足跟骨的局部部位)的平面构形相匹配，事先说明。
请再参阅图2所示，该外包覆层21能设有至少一空气通道211，该空气通道211连通该外包覆层21的内外，使得该第一容纳空间中的空气能经由该空气通道211而流出至该外包覆层21外。另，在该第一实施例中，该等颗粒22能直接被填装至该外包覆层21内，以使该外包覆层21呈现一预定厚度，且维持在一柔软状态，又，该等颗粒22能在该外包覆层21之内移动。此外，该个性化鞋垫2还设有一启闭组件24，该启闭组件24气密安装在该外包覆层21上对应于该空气通道211的位置，例如，可设在该空气通道211内部，或是设在该外包覆层21的内侧及/或外部，在该第一实施例中，如图2所示，该启闭组件24位于该外包覆层21的内侧。又，该启闭组件24能使该空气通道211呈单向往外排气状态，或者能使该空气通道211转换于呈双向导通状态与呈双向不导通状态。此外，为了避免该等颗粒22 可能经由该空气通道211而流出至该外包覆层21外，该启闭组件24还可增加阻挡结构(如：过滤网)，使其同时具有阻挡该等颗粒22经由该空气通道211流出的效果。
请再参阅图2及图3A所示，为避免图式过于复杂，图3A省略绘制该等颗粒22。该负压辅助组件23能位于该外包覆层21内，其位置与数量能视实际需求而定，如图3A所示，能够仅有单一个负压辅助组件23；或者，如图3B所示，能够具有多个负压辅助组件23；又，该负压辅助组件23一般能位于该外包覆层21内邻近底面的位置，其顶面则能堆栈该等颗粒22。该负压辅助组件23的特性在于，当其受到外力压迫而变形(变小)时，会产生一恢复力，而当外加压力消失时，能使自身能朝向原状的状态恢复，又，该负压辅助组件23自身具有至少一容气空间26，当其处于外力压迫而变形(变小)的状态下，会使其内的容气空间26中的空气被排出，反之，当外力消失后，其自身的恢复力也会迫使其吸取外部空气至各该容气空间26中。例如，在该第一实施例中，该负压辅助组件23能为开放式多孔性弹性材料(如：泡棉)，且其上的集体孔洞或孔隙即为该容气空间26。其中，前述“开放式”一词，指该容气空间26直接与该负压辅助组件23的外部空间相连通，后续实施例所述及的“开放式”亦相同于前述定义。
请再参阅图2及图3A所示，当使用者的脚掌(整体或局部)踩踏或施压力在该外包覆层21的顶面时，该等颗粒22随着脚掌的立体构形作位移而完成塑形(即，成形)，且该外包覆层21内的空气会因脚掌所施加的压力，经由该空气通道211，排出至该外包覆层21之外；又，该负压辅助组件23亦会受到前述压力影响而缩小其占用容积，其容气空间26内的空气亦会被排出该负压辅助组件23，再经由该空气通道211而排出至该外包覆层21之外。又，当用户透过该启闭组件24将该空气通道211气密封合，使空气无法由大气侧流入该外包覆层21内，并移除脚掌所施加的压力后，该负压辅助组件23会因自身的恢复力而扩张，并会相对大比例地吸收该等颗粒22间的残留空气，以在该外包覆层21内形成负压，使得该等颗粒22因而定形在相互紧密贴靠且不易位移的状态，以得出该个性化鞋垫2(如图4所示)。
对于使用者来说，该个性化鞋垫2的成型主要需经过“成形”与“定形”二个阶段来完成。在“成形”阶段，使用者能将脚掌置放在该外包覆 层21上，并施加压力，本阶段仅容许在该外包覆层21内的空气单向经由该空气通道211，排出至该外包覆层21之外；在“定形”阶段，使用者脚掌将离开该外包覆层21上，以移除其所施的压力，本阶段不容许在该外包覆层21外部的空气单向经由该空气通道211，流到该外包覆层21的内部。承前所述，该启闭组件24需满足以下两种条件之一：
1.不论是“成形”阶段与“定形”阶段，该空气通道211只呈单向往外排气状态；根据前述条件，该启闭组件24能使用一逆止阀来达成，即，将只呈单向往外排气方向的逆止阀，气密连接至该空气通道211(如：位于该空气通道211内或外)；或
2.在“成形”阶段，该空气通道211呈双向导通状态，而在“定形”阶段，该空气通道211则转换成呈双向不导通状态。根据前述条件，该启闭组件24可为塞子、气密胶带、阀门或其它等手段来达成；因此，在“成形”阶段，该空气通道211呈双向导通状态，在脚掌施加压力完成塑形及排出空气后，而脚掌仍持续施加压力时，使用塞子或气密胶带等组件，以手动塞住或贴住该空气通道211后，再移除脚掌施力，即完成“定形”阶段。
根据使用上的需求，该负压辅助组件23的设计，可具有多样性考虑，能达成不同功效：
1.如第3A与3B图所示，该负压辅助组件23所覆盖或放置的位置，能够为：1-1.覆盖全鞋垫；1-2.覆盖前脚掌区域；1-3.覆盖足弓区域；1-4.覆盖足跟区域；或1-5.前述两个以上的组合。
2.依该负压辅助组件23的材料与型式，大抵可区分如下样式：
2-1.开放式多孔性弹性材料，如：泡棉、海绵等，且能够为单一个整体或是由多个独立组件拼凑而成；前述“多孔性”，指该材料本身即具有许多个孔洞或空隙，集体的该等孔洞或孔隙，即可视为该容气空间26；
2-2.开放式中空弹性体，包含：开放式中空弹性圆管、开放式中空扁平形弹性体、开放式中空球状形弹性体及开放式中空弹性颗粒等；其中，该开放式中空弹性颗粒，指被填装入该外包覆层内的该等颗粒，具有中空内部，且该中空内部直接连通该等颗粒的外部，故，除具有颗粒本身的功能外，还可兼作为该负压辅助组件使用；
2-3.双逆止阀式结构，为一非开放式中空弹性体，并设有各别自该中空 内部连通至该外部的一第一出口与一第二出口，其分别气密连接一第一逆止阀与一第二逆止阀；该第一逆止阀的设计，为使该负压辅助组件外部的空气，只能单向流入至该中空内部(即容气空间26)，而该第二逆止阀则使该中空内部的空气(即容气空间26)，只能单向流出至该负压辅助组件外部。
3.另外，请参阅图5(为图3B的成型后的鞋垫的A-A足跟剖面图)所示，使用者在行走时，该个性化鞋垫2的上半部HU的该等颗粒22，因受到负压影响而定形在相互紧密贴靠且不易位移的状态，故其整体硬度较高，同时，该个性化鞋垫2的下半部HD的负压辅助组件23，其自身能随着外力而改变容积，故具有缓冲能力，因此，该个性化鞋垫2在设有负压辅助组件23处，除能提供脚底支撑力外，还具有缓冲性；
4.以该个性化鞋垫2的纵向剖面观之，如图4所示，该负压辅助组件23会占用部分容积，故能大幅减少颗粒22的使用数量，以降低该个性化鞋垫2的生产成本，同时仍能塑型成适合该使用者的足底立体构形。
在本发明的第二实施例中，其使用的负压辅助组件不局限于块状的泡棉，而能采用开放式中空弹性体，在此以条状的中空弹性管体来代表说明，如图6上方的多个中空弹性管体(负压辅助组件33)所示，该开放式中空弹性管体亦能够由透气材料制成，因此，除其管内本身所具有较大的容气空间36外，还能加上其管壁内所具有的多个小容气空间(即，孔洞与孔隙)；该负压辅助组件33所排出的空气，最后能经由该空气通道211(如图6右方中间处的空气通道211)所排出，又，在该第二实施例中，该启闭组件24为气密胶带，且能位于该外包覆层21的外侧。
请再参阅图6所示，在该第二实施例中，使用双逆止阀式结构的负压辅助组件43(如图6的下方的扁圆形非开放式中空弹性体)，其由不透气材料或结构所制成，且气密连接一第一逆止阀431与一第二逆止阀432，其中，该第一逆止阀431只能使该负压辅助组件43的外部空气流入其中空内部(即容气空间46)内，如图6的第一逆止阀431上方的箭头方向；该第二逆止阀432则只能使该负压辅助组件43的中空内部(即容气空间46)内的空气，流出至外部，如图6的第二逆止阀432下方的箭头方向，且与空气通道211气密连通；当该外包覆层21的足跟处受到外力重复踩踏、挤压及释放时，其内的空气能依序经由该第一逆止阀431、容气空间46、第二逆止 阀432与空气通道211而流出至该外包覆层21之外。在此特别一提，当使用者连续踩踏该负压辅助组件43时，还能够在该外包覆层21内形成较大的负压。该第一逆止阀431与第二逆止阀432仅供空气能单向流动，因此，只要是能达成前述仅供空气能单向流动的结构，例如，鸭嘴阀(Duckbill valve)、截气阀(air check valve)等，都属于本发明所称的该第一逆止阀431与第二逆止阀432。
请参阅图7A所示，在本发明的第三实施例中，该等颗粒22能够先填装至一内包覆层25的第二容纳空间中，其中，该内包覆层25是由透气材料(如：具弹性或挠性的透气织物或透气塑化膜)所制成，且其平面构形能与脚掌的整体或局部的平面构形相匹配，使得该内包覆层25呈现一预定厚度，以维持在一柔软状态，该等颗粒22能在该内包覆层25的内移动，其粒径会大于该内包覆层25的透气孔径，使得该等颗粒22不会在外力挤压下而脱离该内包覆层25。又，该内包覆层25的周缘能被封合，且其连同内部的该等颗粒22能一并被置入该外包覆层21内，意即，该等颗粒22是间接被置入于该外包覆层21中。又，该负压辅助组件23及该启闭组件24能够位于该内包覆层25外，如此，在生产过程中，便能够将负压辅助组件23、启闭组件24与内包覆层25分别置入于该外包覆层21内，不仅程序上较为简单，且能够使负压辅助组件23及该启闭组件24位于预期位置。在本发明的其它实施例中，该负压辅助组件23亦能够连同该等颗粒22被装设于该内包覆层25中，事先说明。
承上，请参阅图7B所示，当使用者的脚掌踩踏在该外包覆层21的顶面时，其在该内包覆层25中的该等颗粒22，随着脚掌的立体构形作位移完成塑形，且该内包覆层25内的空气会因脚掌所施加的压力，而排出至该内包覆层25；另，该负压辅助组件23在处于外力压迫下，亦会排出空气，前述该内包覆层25与该负压辅助组件23被排出的空气连同原在该外包覆层21内的空气，经由该空气通道211，排出至该外包覆层21之外。又，使该空气通道211被气密封合，当该外包覆层21不再受力(即，不再被踩踏)后，该负压辅助组件23自身的恢复力会迫使其吸取外部空气，使得位于该内包覆层25内完成塑形的该等颗粒22，彼此间因负压影响而定形在相互紧密贴靠且不易位移的状态，以得出该个性化鞋垫2。
另外，请参阅图7C所示，为了使该个性化鞋垫2能长时间保持其塑形后的状态，其还能够在完成定形(即，该等颗粒22定形在相互紧密贴靠且不易位移的状态)，且已将该空气通道211气密封合后，进行加热作业。其中，该等颗粒22能由低熔点或低初熔温度(如：60℃～85℃)的热塑性弹性体材料(如：TPU、TPEE、TPS、TPR、SEBS…等)制成，其熔点或初熔温度会低于该个性化鞋垫2的其它组件(如：外包覆层21、负压辅助组件23…等)，即，当该等颗粒22呈熔融状态时，该个性化鞋垫2的其它组件能同样能保持其完整性而不会呈熔融状态。又，该加热作业能够以热开水、烤箱、吹风机或微波炉来进行，不需要使用专业的加热设备，以提高个人使用上的便利性。在进行加热作业时，该等颗粒22至少其表面会呈熔融状态，使得相邻的该等颗粒22能熔接成一体，进而固形出寿命长久的个性化鞋垫2。如此，在长时间的使用下，若该外包覆层21或内包覆层25发生破损时，由于该等颗粒22已黏结成一体，因此，该个性化鞋垫2仍能保持在原有的脚底立体构形，以有效延长该个性化鞋垫2的使用寿命。
除了以热塑性弹性体材料来制作该等颗粒22之外，在本发明的其它实施例中，该等颗粒22还能够与接合材料27均匀混合，使得该接合材料27能均匀地附着在各该颗粒22的表面(如图8所示)，其中，该接合材料27能呈粉末状、液态膏状…等，且其包括黏着材料(Binder)(如：TPU热熔胶、EVA热熔胶…等)271及/或吸附材料(Absorbent)(如：红外线吸收材料、电磁波吸收材料…等)273，该黏着材料271与吸附材料273能如图8般，附着在颗粒22的表面上，或是完全包覆于颗粒22的表面。又，该接合材料27的熔点会低于该个性化鞋垫2的其它组件(如：颗粒22、外包覆层21、负压辅助组件23…等)的熔点，且该接合材料27与该等颗粒22能直接或间接填装至外包覆层21内。当该个性化鞋垫2还包含内包覆层25时，该等接合材料27的粒径能大于该内包覆层25的透气孔径，以使该等接合材料27仅能在该内包覆层25内位移。在进行加热作业后，该等接合材料27能熔融而使相邻的该等颗粒22熔接成一体，进而固形出寿命长久的个性化鞋垫2。
在此特别一提，该个性化鞋垫2在没有进行加热作业时，其是能够重复塑形，用户只要开启该空气通道211，使得外界空气进入该外包覆层21 即可。此外，本发明的空气通道211的数量不限制只有一个，亦能够为多个(如图6所示)，当其中一个空气通道211被占用(如第二实施例，其底部的空气通道211被该第二逆止阀432所独占)时，则另一个空气通道211能够被开启，以使外界空气进入该外包覆层21。必要时，该空气通道211亦可用来填充或移除颗粒22用。
下面就本发明的个性化鞋垫2的制造流程，进行说明，请参阅图2及图9所示，在步骤501中，执行一填装作业，依据该个性化鞋垫2的设计，将该启闭组件24与该负压辅助组件23设置于该外包覆层21的预定位置上，并将该等颗粒22直接或间接填装至该外包覆层21内(例如，颗粒22能先被填装至该内包覆层25后，该内包覆层25才被装设至该外包覆层21内)，以使该外包覆层21呈现一预定厚度，且该等颗粒22能在该外包覆层21(或该内包覆层25)之内移动，然后气密封闭填装口，以完成该填装作业；之后，在步骤502中，可执行一预先成型作业，此作业通常在工厂端执行，即根据一初步足底立体构形，前述“初步足底立体构形”泛指某些代表性的足底立体模型，例如，符合大多数人的脚底状态或是根据使用者所预想设计的脚底状态，之后，将已填装完成的鞋垫铺平放置或置于支撑治具(即，鞋模台)上，使该启闭组件24令该空气通道211呈单向往外排气状态或是双向导通状态，将该初步足底立体构形置放于该鞋垫的外包覆层上，并施予适当压力，使该等颗粒22随顺着该足底立体构形作位移而完成塑形，再用抽气装置(如：真空泵)经由该空气通道211对该外包覆层21抽气，以得到强力定形(较高真空)效果，最后再气密封合该空气通道，即完成该预先成型作业。此作业可使该鞋垫长期维持着代表性状态作储存，也将便利于今后使用者的使用。
另，在步骤503中，执行一成形作业，在该外包覆层21的内部与外部的气压在相同或实质上相同，且使该启闭组件24令该空气通道呈单向往外排气状态或是双向导通状态的情况下，在使用者脚掌的整体或局部踩踏并施压力在该外包覆层21上的状态下，能使该等颗粒22随着脚掌的整体或局部的立体构形作位移而完成塑形，且该外包覆层21内的空气会因脚掌整体或局部施加的压力，经由该空气通道211，排出至该外包覆层21之外，同时，该负压辅助组件23亦会受到前述压力影响而缩小其占用容积，其内 的空气亦会经由该空气通道211而排出至该外包覆层21之外，此时，该外包覆层21的顶面会形成匹配、符合于使用者的脚掌状态的立体构形；在步骤504中，执行一定形作业，使该启闭组件24令该空气通道仍维持单向往外排气状态或转换为双向不导通状态，使得该外包覆层21外部的空气无法流入该外包覆层21内，在移除脚掌所施加的压力后，该负压辅助组件23会因自身的恢复力而扩张，并吸收该等颗粒22间的残留空气，使得该等颗粒22因负压影响而定形在相互紧密贴靠且不易位移的状态，以得出该个性化鞋垫2。再者，在步骤505中，执行一加热作业，以使相邻的该等颗粒22能直接或间接熔接成一体，进而固形出寿命长久的个性化鞋垫2；又，对于某些材料在加热时会释放气体，将破坏原有负压状态，而使已定形的状态改变，故在步骤505时，可采用边加热边对鞋垫抽真空的模式作业，以保证其立体构形不被改变。在上述本发明的制程中，其步骤502与505，能够视产品需求而省略。
兹特别说明当该启闭组件24是使用逆止阀时，其具有如下优点：
1.可直接将该个性化鞋垫2置于鞋内，于踩踏或行走中，即会自动完成该个性化鞋垫2的成型(成形及定形)，其免除了需要先在鞋子外面，以手动方式作成形及定形操作，完成后再将该个性化鞋垫2置入鞋内使用。主要原因在于，若该启闭组件24为塞子、气密胶带…等，其在对该空气通道211作导通及不导通的切换，一般须以手动方式操作，故需在鞋外进行。
2.符合于使用者在日常行动下的足底立体构形。
3.于日常行动中，将自动补足真空(避免微漏困扰)。
4.可塑造出满足特殊构形需求的个性化鞋垫。如：一般扁平足患者为了达到矫正目的，希望该鞋垫的立体构形，能符合其脚掌在轻微受压(或未受压)时的足底立体构形，或希望在某处、某方向具有倾斜、突起等的特殊构形要求(如刺激穴道)，此时若使用该逆止阀的鞋垫，即可以手动方式，适当压挤该外包覆层，令外包覆层(及/或内包覆层)内的部分空气，在控制下经由该空气通道，慢慢排出至该外包覆层之外，在达到某轻微负压时，可使该些颗粒呈现互相接触，保持不任意移动的状态，但以手指施力于该外包覆层上时，却可容易移动该些颗粒，并保持该移动后的立体形态；利用此手动方式，并与足部作比对，必要时利用适当工具来辅助塑形，可轻易、 快速完成该特殊构形需求的塑形作业，最后再加强负压的建立，以完成定形作业，即塑造出满足特殊构形需求的个性化鞋垫2。
以上所述，仅是本发明的较佳实施例，本发明所主张的权利范围，并不局限于此，本领域技术人员依据本发明所公开的技术内容，可轻易想到的等效变化，均应属不脱离本发明的保护范畴。
