具体实施方式
以下,通过发明的实施方式对本发明进行说明,但以下的实施方式不限定权利要求书所记载的发明。另外,不局限于实施方式中所说明的特征的组合全部方式都是发明的解决手段所必需的。
图1是表示本发明的第一实施方式所涉及的托板100的立体图。托板100载置物品。托板100例如在物流中使用,用于物品的保存和输送。
本例的托板100具备主体部10和多个腿部16。本例的主体部10是板形状。将主体部10中载置物品的表面称为载置面12,将与载置面12相反一侧的表面称为背面14。
在背面14设置有多个腿部16。多个腿部16可以与主体部10一体形成,也可以粘合于主体部10。各个腿部16以规定的间隔配置。优选腿部16以格子状排列,以使得叉车等的抬起件能够通过各个腿部16之间。
图2是表示托板100的局部剖切的图。图2中示出主体部10的局部的剖面。托板100具有基材20和表面涂覆层22。基材20由发泡合成树脂形成。
作为一个例子,形成基材20的合成树脂为高分子化合物。作为更具体的例子,形成基材20的合成树脂由从聚苯乙烯、聚乙烯、聚丙烯以及聚氨基甲酸乙酯选择出的一种以上的材料形成。发泡合成树脂是指在这些合成树脂中分散有微小的气泡而成的材料。在一个实施例中,基材20由发泡苯乙烯(发泡聚苯乙烯)形成。
表面涂覆层22覆盖基材20的表面而形成。表面涂覆层22由聚脲树脂形成。聚脲树脂是具有例如由异氰酸酯和氨基的化学反应而形成的尿素键的树脂。作为一个例子,聚脲树脂使聚异氰酸酯和多胺反应而形成。聚脲树脂也可以使用将比重1.09~1.12的聚异氰酸酯化合物、和比重1.13~1.02的作为固化剂的合成树脂以容积比1:1或者重量比109:100左右进行了混合的混合溶剂而形成。
表面涂覆层22优选形成于基材20的整个表面。换句话说,表面涂覆层22覆盖主体部10的载置面12、背面14以及侧表面全部。侧表面是指载置面12和背面14之间的表面。另外,表面涂覆层22覆盖腿部16的全部的表面。此外,腿部16的表面中的与主体部10连接的表面可以形成有表面涂覆层22,也可以未形成有表面涂覆层22。
表面涂覆层22的厚度T1小于基材20的厚度T2。作为一个例子,基材20的厚度为3cm以上,表面涂覆层22的厚度T1为5mm以下。
基材20由发泡合成树脂形成,因此非常轻型。另外,表面涂覆层22由聚脲树脂形成,因此具有高强度、优秀的耐水性、以及优秀的耐冲击性。因此,通过表面涂覆层22涂覆基材20的表面,从而能够提供超轻型、且强度、耐水性以及耐冲击性优秀的托板100。
本例的托板100非常轻型,因此使运输和保存等变容易,能够减少物品的输送等所耗费的能量等成本。因此,也能够对环保做出贡献。
另外,与木制、金属制等托板相比,加工性优秀,而且能够以低成本制造。另外,与木制托板等相比,抗腐蚀性也优秀,因此运转成本也能够减少。
图3是表示形成基材20的发泡合成树脂的发泡倍率、和表面涂覆层22的厚度T1之间的关系的图。在本例中,表面涂覆层22的厚度T1根据基材20的发泡倍率来决定。发泡倍率表示例如利用蒸气等加热合成树脂的颗粒(原料微珠)而使之膨胀时的膨胀比率(体积比)。更具体而言,在50倍的发泡体中空气占产品整体(体积)的98%,合成树脂占2%。一般发泡倍率与发泡合成树脂的强度成反比。例如发泡倍率为30倍的发泡合成树脂成为发泡倍率为60倍的发泡合成树脂的两倍的强度,体积成为一半左右。
发泡倍率根据基材20的用途来选择。根据用途,决定基材20所应该具有的厚度和强度。根据基材20的强度来决定发泡倍率。
表面涂覆层22的厚度T1以与发泡倍率大体成正比的方式设定。通常,若使发泡倍率为A,则表面涂覆层22的厚度T1为A/20[mm]左右。例如,在标准的托板用途中,发泡倍率为40倍的情况下,优选表面涂覆层22的厚度T1为2mm左右。另外,在发泡倍率为60倍的情况下,优选表面涂覆层22的厚度T1为3mm左右。通过使表面涂覆层22的厚度T1与发泡倍率A成正比,从而基材20的强度越弱,越能够使表面涂覆层22的厚度T1变大而维持托板100整体的强度。
但是,表面涂覆层22的厚度T1也可以相对于标准的厚度而增减。作为一个例子,在欲具有更高强度的情况下,使表面涂覆层22的厚度T1增加,在欲更加减少成本的情况下,使表面涂覆层22的厚度T1减少。作为一个例子,表面涂覆层22的厚度T1也可以是图3中虚线所示的下述的范围。
(A/20)-1≤T1≤(A/20)+1[mm]
此外,发泡合成树脂的发泡倍率能够根据合成树脂的材料种类、发泡合成树脂的每单位体积的重量来推断。即,根据发泡合成树脂的每单位体积的重量和合成树脂的材料,来推断发泡前的合成树脂的体积。而且,根据推断出的发泡前的合成树脂的体积、和发泡合成树脂的单位体积,来计算发泡倍率。
图4是表示树脂成形体的制造工序的一个例子的流程图。首先在用途选择阶段S201中,选择树脂成形体的用途。作为树脂成形体的用途,除了托板100之外,可举出后述的保护件和箱体,但不限定于这些。本例中树脂成形体的用途为托板100。
接下来,在发泡倍率选择阶段S202,选择用于树脂成形体的发泡合成树脂的发泡倍率。发泡倍率可以根据S201中选择出的用途来决定。作为一个例子,存在在制造保护件的情况下的树脂成形体的厚度小于制造托板100的情况下的树脂成形体的厚度这种状况。例如,使保护件的厚度成为托板100的厚度的1/3左右。该情况下,制造保护件的情况下的发泡倍率也可以设定为制造托板100的情况下的发泡倍率的1/3左右。
接下来,在基材成形阶段S203,使发泡合成树脂的基材以规定的形状成形。例如,使发泡合成树脂的基材20以托板100的形状成形。也可以是,在S203中,将以立方体成形的基材20切断为规定的形状。另外,也可以是,在S203中,使多个部件成形。例如也可以使托板100的主体部10和腿部16分别成形。
接下来,在参数设定阶段S204中,设定在喷射表面涂覆材料时的各参数。该参数包括例如针对基材20的单位面积在每单位时间的表面涂覆材料的喷射量等。针对基材20在每单位面积的喷射量如后述那样,能够根据基材20的输送速度等做调整。
另外,在热压阶段S205中,对基材20进行加热和按压。通过加热基材20,将基材20所包括的水分除去。由此,能够减少在基材20表面形成的表面涂覆层22的凹凸。在基材20含较多水分的情况下,例如导致托板100的主体部10以向上侧凸出的方式翘曲。另外,通过按压基材20,从而使基材20表面的气泡破裂,基材20表面的树脂密度高于基材20中心的树脂密度。由此,在基材20表面喷射表面涂覆材料时,防止表面涂覆材料在基材20内部扩散。S204和S205可以任一个先进行,也可以同时进行。
接下来,在喷射阶段S206,在基材喷射表面涂覆材料。在S206中,优选在各个基材的整个表面喷射表面涂覆材料。
接下来,在干燥阶段S207中,使表面涂覆材料干燥。由此,在基材表面形成表面涂覆层22。
另外,也可以是,在设备安装阶段S208,在树脂成形体安装ID设备。ID设备中存储对树脂成形体进行识别的识别信息,将识别信息向外部发送,或者从外部读出。ID设备也可以具有:与外部的读出装置磁通耦合而工作的电路、或者将来自外部的电波转换为工作电力的电路等。
图5A是对热压阶段S205的一个例子进行说明的图。在本例中,使用多个自转的辊306来输送基材20。在输送途中,通过热压部305,对基材20进行加热和按压。热压部305以能够自转的方式设置于与任一个辊306对置的位置。另外,热压部305内置加热器等加热单元。
辊306和热压部305的距离小于热压前的基材20的厚度。通过使基材20在辊306和热压部305之间通过,来按压基材20。
图5B是表示在表面形成有表面涂覆层22的基材20的图。基材20的靠表面侧的区域21的发泡倍率小于基材20的中心的区域23的发泡倍率。基材20的中心是指基材20的厚度方向上的中心。
换句话说,区域21的树脂密度大于区域23的树脂密度。例如将使基材20在厚度方向上三等分得到的各区域设为区域21、区域23、区域21。此时,区域21的每单位体积的平均质量大于区域23的该每单位体积的平均质量。
根据这样的构造,在喷射阶段S206,能够抑制表面涂覆材料向基材20的内部扩散。因此,能够高精度地控制表面涂覆层22的厚度。因此,能够高精度地控制基材20和表面涂覆层22整体的强度。
图6是对用于喷射阶段S206的制造装置300的一个例子进行说明的立体图。在制造装置300中,也使用多个自转的辊306来输送基材20。用于S205和S206的装置也可以一体设置。换句话说,通过了用于S205的装置的树脂成形体被向用于S206的制造装置300自动地输送。图6中,示出托板100,作为树脂成形体的一个例子。此外,在制造托板100的情况下,也可以设置在热压阶段S205之后在主体部10上粘合多个腿部16的装置。
制造装置300具备:框体302、支承部304、多个辊306、控制装置308、侧表面用喷射装置310、下表面用喷射装置312以及上表面用喷射装置314。本例的框体302具有平行配置的两根导轨。在两根导轨间沿着规定的输送方向排列有多个辊306。框体302具有使多个辊306旋转的旋转机构。支承部304将框体302支承在规定的高度。本例中,各个辊306通过一边与基材20的表面接触一边旋转,来输送基材20。
侧表面用喷射装置310设置于框体302的两侧。在侧表面用喷射装置310的与框体302对置的表面设置有一个以上的喷射口311。在本例中,多个喷射口311沿高度方向排列。至少一个喷射口311配置于比输送基材20的输送面高的位置。另外,也可以至少一个喷射口311配置于比该输送面低的位置。从各个喷射口311喷射表面涂覆材料。表面涂覆材料是液状的聚脲树脂。在图6中,用虚线示意性地示出喷射的表面涂覆材料。
下表面用喷射装置312在比基材20的输送面低的位置,具有与基材20的输送面对置的一个以上喷射口311。在本例中,多个喷射口311沿与基材20的输送方向正交的方向排列。
上表面用喷射装置314在比基材20的输送面高的位置,具有与基材20的输送面对置的一个以上的喷射口311。在本例中,多个喷射口311沿与基材20的输送方向正交的方向排列。控制装置308在基材20通过各个喷射装置前的时刻,使各个喷射装置喷射表面涂覆材料。
通过这样的构造,能够在树脂成形体的各表面喷射表面涂覆材料。此外,也可以在至少一部分的辊306设置有使树脂成形体一边在输送面内旋转一边输送树脂成形体的机构,以能够通过侧表面用喷射装置310,在树脂成形体的全部的侧表面上喷射表面涂覆材料。
另外,侧表面用喷射装置310、下表面用喷射装置312以及上表面用喷射装置314也可以分别设置有多个。另外,侧表面用喷射装置310、下表面用喷射装置312以及上表面用喷射装置314的顺序不限定于图6的例子。
图7A是对下表面用喷射装置312的喷射面的高度H1进行说明的图。喷射面是指设置有喷射口311的表面。通过调整喷射面的高度H1,能够调整喷射口311与树脂成形体的距离。喷射口311与树脂成形体的距离越是近,从喷射口311喷射的表面涂覆材料附着于基材20的每单位面积上的量越是增加。换句话说,通过调整喷射面的高度H1,从而能够控制在基材20的下表面(图6的例子中,与托板100的载置面12对应的表面)形成的表面涂覆层22的厚度。
图7B是用于对侧表面用喷射装置310的喷射面与框体302间的距离D进行说明的图。通过调整距离D,能够调整喷射口311与树脂成形体的距离。换句话说,通过调整距离D,能够控制在基材20的侧表面上形成的表面涂覆层22的厚度。
图7C是对上表面用喷射装置314的喷射面的高度H2进行说明的图。通过调整喷射面的高度H2,能够调整喷射口311与树脂成形体的距离。换句话说,通过调整高度H2,能够控制在基材20的上表面(图6的例子中,与托板100的背面14对应的表面)形成的表面涂覆层22的厚度。
图6所示的控制装置308对该高度H1、距离D以及高度H2进行控制。由此,能够独立地控制在树脂成形体的各表面形成的表面涂覆层22的厚度。在树脂成形体的各表面形成的表面涂覆层22的厚度可以相同,也可以不同。例如,在托板100的载置面12形成的表面涂覆层22可以厚于在托板100的侧表面形成的表面涂覆层22。由此,能够使与物品接触的表面涂覆层22的强度增加。
在本例子中,使喷射阶段S206中形成于基材20的正面的表面涂覆材料的厚度与形成基材20的发泡合成树脂的发泡倍率成正比。控制装置308通过对基材20的输送速度和各喷射装置的喷射口与基材20间的距离中的至少一者进行调整,来控制表面涂覆材料的厚度。例如控制装置308在欲使表面涂覆材料的厚度增加的情况下,使基材20的输送速度降低,或者使各喷射装置的喷射口与基材20间的距离变小。该距离能够通过上述的高度H1、距离D以及高度H2来调整。
若将由辊306形成的基材20的输送速度设为V,将基材20与各喷射装置的喷射口间的距离设为L,则表面涂覆层22的膜厚T1与V成反比,且与L2成反比。换句话说,T1与V×L2成反比。控制装置308也可以基于该关系来设定输送速度V和距离L。例如,在使表面涂覆层22的厚度成为两倍的情况下,可以将输送速度V设定为一半,也可以将距离L设定为0.51/2倍。
另外,控制装置308也可以根据树脂成形体的宽度、长度、高度来调整各喷射装置的喷射口与基材20间的距离。例如,在树脂成形体更大的情况下,使该距离更大,在较大的范围均匀地喷射表面涂覆材料。
此外,在制造物流用的托板100的情况下,托板100的长度和宽度以例如JIS标准决定为1100mm。优选各喷射装置的高度H1、距离D以及高度H2在能够制造该尺寸的树脂成形体的范围内能够做变更。
图8是制造装置300的侧视图。制造装置300具有表面涂覆准备区域、表面涂覆区域以及干燥区域。将被加热以及按压了的基材20输送至表面涂覆准备区域。基材20在配置有侧表面用喷射装置310、下表面用喷射装置312以及上表面用喷射装置314的表面涂覆区域通过。由此,在基材20的整个表面层叠有表面涂覆材料。
此外,也可以在表面涂覆区域设置防止表面涂覆材料向周围飞散的罩。优选该罩至少包围设置有侧表面用喷射装置310、下表面用喷射装置312以及上表面用喷射装置314的区域。
通过了表面涂覆区域的基材20被输送至干燥区域。在干燥区域配置有一个以上干燥部318。干燥部318例如为鼓风机。干燥部318朝向形成于基材20的正面的表面涂覆材料鼓风。此外,本例的制造装置300针对表面涂覆区域的各辊306,具有辅助部件316。
图9是表示辅助部件316的一个例子的侧视图。在基材20的与输送面相反一侧,与各个辊306对置地配置有辅助部件316。在本例中,针对各个辊306,设置有第一辅助部件316-1和第二辅助部件316-2。
第一辅助部件316-1配置得比第二辅助部件316-2靠辊306的旋转方向的上游侧。第一辅助部件316-1使附着于辊306的表面的表面涂覆材料从辊306脱离。第一辅助部件316-1也可以具有:与辊306的表面接触而与辊306的旋转对应地将表面涂覆材料刮除的脱离部。将脱离的表面涂覆材料从排出口320排出。
第二辅助部件316-2在辊306的表面涂覆有使表面涂覆材料容易脱离的脱离材料。脱离材料例如为油。第二辅助部件316-2也可以具有:与辊306的表面接触而与辊306的旋转对应地涂覆脱离材料的涂覆部。
根据图5A~图8所示的装置,使将构造和尺寸规格化了的基材20在辊输送机上移动期间,从配置于辊输送机的上部、下部、侧部的喷射装置喷射聚脲树脂。其后,使聚脲树脂干燥而在基材20的表面形成聚脲树脂的表面涂覆层22。通过这样的方法,能够以短时间量产均质的树脂成形体。
图10A是表示托板100的其他构造例的立体图。本例的托板100除了图1所示的托板100的构造之外,还具有定位部17。定位部17设置于载置面12。定位部17在载置面12上载置了其他托板100的情况下,对其他托板100的腿部16的位置进行限定。此外,定位部17也与托板100的其他部件相同,由基材20和表面涂覆层22形成。定位部17可以与主体部10一体形成,也可以粘合于主体部10。
本例的定位部17设置于载置面12的各个角。各个定位部17在载置面12的角上沿着正交的两个边,在规定的长度内形成。载置面12的各个边的定位部17的长度也可以与腿部16的长度相同。本例的腿部16具有长度l1、宽度w1、高度h1。定位部17的长度和宽度也可以与腿部16相同。定位部17的高度小于腿部16的高度h1。例如定位部17的高度为腿部16的高度的一半以下。
在本例中,主体部10的长度l和宽度w相同。在一个实施例中,主体部10的长度l和宽度w为1100mm。另外,主体部10的高度h2为30mm。另外,腿部16的长度l1、宽度w1以及高度h1为100mm。另外,各个腿部16的间隔p为400mm。
图10B是层叠了两个托板100的立体图。上侧的托板100-2的腿部16的位置由下侧的托板100-1的定位部17来限定。
图11是表示托板100的其他构造例的立体图。本例的托板100除了图1所示的托板100的构造之外,还具有定位部18。定位部18设置于载置面12。定位部18设置于与各个腿部16对置的位置。
定位部18是设置于载置面12的凹陷。定位部18的深度小于主体部10的厚度。换句话说,定位部18未贯通主体部10。定位部18的深度例如为主体部10的厚度的一半以下。另外,定位部18的长度l2和宽度w2与腿部16的长度l1和宽度w1相等,或比腿部16的长度l1和宽度w1稍大。通过这样的构造,也能够容易地层叠多个托板100。
图12是表示托板100的其他构造例的立体图。在本例的托板100固定有ID设备19。ID设备19存储有对托板100进行识别的信息,并且向外部发送识别信息。例如通过使读出装置接近ID设备19,从而读出托板100的识别信息。
也可以在托板100以相对于主体部10的中央对称的方式设置有多个ID设备19。例如,也可以在主体部10的各边的中央设置有ID设备19。由此,能够不考虑托板100的朝向而从ID设备19读出识别信息。ID设备19也可以埋入腿部16中。此外,本例的ID设备19在图1、图10A以及图11所示的任一个例子中都能应用。
另外,在图1、图10A以及图11所示的托板100中,各个腿部16也可以具有空洞。由此,能够使托板100进一步轻型化。另外,也可以在该空洞收纳ID设备19。另外,ID设备19也可以贴附于主体部10的背面。
另外,ID设备19也可以存储有表示托板100的位置信息等的状态的信息。也可以由外部的写入装置写入该信息。ID设备19也可以例如以Bluetooth(注册商标)Low Energy(BLE)方式,以规定的周期发送该信息。也可以通过内置于移动终端等的接收器来接收该信息。移动终端也可以将接收了的信息发送至云服务器等。通过用移动终端等访问云服务器,能够掌握各个托板100的状态。
图13是表示主体部10的背面14的腿部16的排列例的立体图。本例与图1所示的托板100对应。多个腿部16中的沿着主体部10的外周设置的腿部16以与主体部10的侧表面成为同一平面的方式配置。另外,在主体部10的内侧也以与主体部10的外周相同的间隔配置有腿部16。
图14是表示腿部16的其他排列例的立体图。本例与图10A和图11所示的托板100对应。多个腿部16中的沿着主体部10的外周设置的腿部16配置得比主体部10的侧表面靠内侧。由此,在层叠了托板100的情况下,上侧的托板100的腿部16由下侧的托板100的定位部定位。此外,在主体部10的内侧,也以与主体部10的外周相同的间隔配置有腿部16。
图15A是表示托板100的表面状态的一个例子的图。图15B是表示托板100的表面状态的其他例子的图。图15A所示的托板100的表面(即,表面涂覆层22的表面)比图15B所示的托板100的表面凹凸小。
图15B所示的状态能够通过改变喷射量而多次喷射表面涂覆材料来实现。具体而言,首先,以规定的喷射量在基材20的整个表面喷射表面涂覆材料。由此,托板100的表面成为图15A所示的凹凸较小的状态。
接下来,相比最初的表面涂覆,减少表面涂覆材料的喷射量,对基材20喷射表面涂覆材料。此时,以表面涂覆材料稀疏地附着于基材20的表面的程度,减少表面涂覆材料的喷射量。由此,托板100的表面成为图15B所示的状态。
图6所示的控制装置308也可以根据树脂成形体的用途来控制树脂成形体的表面的凹凸状态。例如,在欲使摩擦系数变大的表面形成凹凸较大的表面涂覆层22。另外,在不需要使摩擦系数变大的表面形成凹凸较小的表面涂覆层22。凹凸较小的表面涂覆层22能够成为接近镜面的状态,能够实现抗菌作用。例如,在托板100的载置面12和背面14形成凹凸比较大的表面涂覆层22,在侧表面形成凹凸比较小的表面涂覆层22。
图16是表示本发明的第二实施方式所涉及的箱体400的一个例子的立体图。箱体400具有内部空间406。本例的箱体400具有收纳部404和盖部402。在收纳部404形成有作为内部空间406的凹陷。盖部402载置在收纳部404的上部而对内部空间406进行封闭。也可以通过盖部402的局部插入内部空间406,来使盖部402固定于收纳部404。箱体400例如作为收纳生鲜食品等的冷藏箱而使用,但箱体400的用途不限定于此。
图17是表示盖部402和收纳部404的局部剖切的图。盖部402和收纳部404与图2所示的托板100同样,具有基材20和表面涂覆层22。基材20具有与图16所示的盖部402和收纳部404相同的形状。
表面涂覆层22覆盖基材20的表面。本例的表面涂覆层22覆盖基材20的与盖部402和收纳部404对应的整个表面。例如,表面涂覆层22形成于箱体400的整个外表面,并且形成于内部空间406的内壁整体。
另外,在盖部402中,如图17所示,在与收纳部404对置的表面也形成有表面涂覆层22。另外,在收纳部404,在与盖部402对置的表面也形成有表面涂覆层22。
此外,也可以是,相比于内部空间406的内壁的表面涂覆层22,使箱体400的外表面的表面涂覆层22上的凹凸更大。由此,箱体400的外表面摩擦系数变大,使运输等变容易,并且能够使内部空间406的内壁成为抗菌状态。通过这样的构造,能够提供轻型并且高强度的箱体400。
图18是表示本发明的第三实施方式所涉及的装具500的一个例子的俯视图。装具500安装于生物体等对象物。图18所示的装具500是覆盖人体的胸部和腹部的至少一部分的保护件。
本例的装具500具有:主体502、冲击吸收部504以及固定部506。主体502也可以由比冲击吸收部504柔软的材料形成。固定部506将主体502固定于对象物。固定部506是带等。
冲击吸收部504设置于主体502的局部区域。冲击吸收部504可以嵌入将主体502的局部挖空了而形成的区域,也可以贴附于主体502的表面。此外,装具500也可以不具有主体502而整体为冲击吸收部504。
图19是表示冲击吸收部504的局部剖切的图。冲击吸收部504与图2所示的托板100相同,具有基材20和表面涂覆层22。基材20具有与图18所示的冲击吸收部504相同的形状。
表面涂覆层22覆盖基材20的表面。本例的表面涂覆层22覆盖基材20的整个表面。通过这样的构造,能够提供轻型并且高强度的装具500。
图20是表示图1所示的托板100的局部剖切的其他例子的图。在图20中,与图2同样示出主体部10的局部的截面。本例的托板100除了图2所示的基材20和表面涂覆层22之外,还具备纤维片30。
纤维片30设置于基材20和表面涂覆层22之间。纤维片30也可以切断强度比表面涂覆层22的切断强度更大。另外,纤维片30也可以耐火性比表面涂覆层22的耐火性更高。纤维片30可以是包含使由规定的材料形成的纤维产生碳化而形成的碳纤维的片材。另外,纤维片30可以是玄武岩纤维片。玄武岩纤维片是包含使玄武岩熔融而形成的纤维的片材。
玄武岩纤维片以二氧化硅(SiO2)作为主成分,包含氧化铝(Al2O3)、氧化钙(CaO)、氧化镁(MgO)、氧化钠(Na2O)、氧化钾(K2O)、氧化钛(TiO2)、氧化铁(Fe2O3+FeO)等。各成分的重量比的含有率为SiO2:51~60%左右、Al2O3:14~19%左右、CaO:5~10%左右、MgO:3~6%左右、Na2O+K2O:3~6%左右、TiO2:0~3%左右、Fe2O3+FeO:9~14%左右。玄武岩纤维片也可以还包含其他成分。
纤维片30至少设置于托板100的载置面12的局部区域。纤维片30可以设置于托板100的背面14,也可以设置于侧表面。
纤维片30也可以比表面涂覆层22薄。纤维片30的厚度可以为1mm以下,也可以为0.6mm以下。通过使用这样的纤维片30,能够不使托板100的厚度增大那么多就能提高强度。
另外,纤维片30的单位体积所包括的空间的体积也可以少于基材20的单位体积所包括的气泡的体积。换句话说,也可以是,与基材20相比,用于形成表面涂覆层22的材料更难以浸透纤维片30。由此,提高托板100的强度,并且能够减少为了形成规定的厚度的表面涂覆层22所需要的表面涂覆材料。
图21是表示在托板100设置有纤维片30的范围的例子的图。在图21中,用网格表示设置有纤维片30的范围。在本例的托板100中,在托板100的载置面12整体设置有纤维片30。另外,在载置面12以外未设置有纤维片30。由此,能够提高载置有物品的表面的强度。
图22是表示在托板100设置有纤维片30的范围的其他例子的图。在本例的托板100中,在载置面12上,在与腿部16对置的区域以外部分,设置有纤维片30。另外,在托板100的背面和侧表面未设置有纤维片30。由此,能够对针对来自上方的载荷的强度比较弱的位置进行加强。另外,通过在图22所示的图案的纤维片30上形成一样的厚度的表面涂覆层22,能够在未配置有纤维片30的区域形成凹陷。也能够将该凹陷作为图11所示的定位部18而使用。
图23是表示在托板100设置有纤维片30的范围的其他例子的图。在本例的托板100中,在载置面12的边缘部设置有纤维片30。另外,在载置面12的边缘部以外部分未设置有纤维片30。由此,能够对强度比较不足的位置进行加强,并且能够减少纤维片30的使用量。
图24是表示图16所示的箱体400的局部剖切的其他例子的图。在本例的箱体400中,箱体400的靠外表面408侧的基材20的表面由表面涂覆层22覆盖。另外,内部空间的内壁410的基材20的表面被内壁表面涂覆层40覆盖。
如上述那样,表面涂覆层22为聚脲树脂。另外,内壁表面涂覆层40是含有陶瓷粉末的涂料等的层。陶瓷粉末是具有抗菌作用的粉末。陶瓷粉末可以是在陶瓷表面涂覆木炭、竹炭等碳化物的粉末,可以是在陶瓷表面涂覆了具有其他抗菌作用的物质的粉末,也可以是使陶瓷粒子担载银离子等具有抗菌作用的物质的粉末。
通过这样的构造,能够提高收纳物品的内部空间的抗菌作用。此外,也可以在外表面408侧,在表面涂覆层22与基材20之间设置纤维片30。纤维片30在图1~图24中说明的各实施方式中,能够适当地设置在表面涂覆层22与基材20之间。
另外,在箱体400的内壁410侧,且在内壁表面涂覆层40与基材20之间,可以设置表面涂覆层22,也可以设置表面涂覆层22和纤维片30。由此,内壁410侧的基材20的强度也能够提高。
