Abstract

本发明涉及液体储存瓶及其制造方法和树脂部件及其制造方法。液体存储瓶包括瓶体和管状管嘴，瓶体在一端处具有树脂制的第一圆筒部，第一圆筒部在其前端处具有开口，管状管嘴用于通过开口倒出容纳在瓶体内部的液体，管状管嘴具有结合至瓶体的树脂制的第二圆筒部。第二圆筒部的内周面焊接至第一圆筒部的外周面。第一圆筒部的外周面设置有沿周向方向延伸的环形凹槽并且使环形凹槽容纳在结合操作期间熔融的树脂的一部分。

Description

液体储存瓶及其制造方法和树脂部件及其制造方法
技术领域
本公开涉及一种用于在其内部容纳液体的液体储存瓶，并且还涉及制造液体储存瓶的方法。
背景技术
在诸如喷墨记录设备的液体喷射设备中使用的液体存储罐包括能够通过用于液体注入的入口端口从单独制备的液体存储瓶再填充液体的那些液体存储罐。期望通过将树脂制的管嘴焊接至也由树脂材料制成的瓶体以气密地密封瓶来制备这种适于再填充的液体存储瓶(在下文中称为“液体再填充瓶”)，以便最大程度地减少瓶的液体内容物弄湿用户的手和在瓶周围发现的一些物体的风险。作为用于制备包括瓶体和管嘴的液体再填充瓶的方法，已知旋转焊接技术，其包括在保持两个圆筒形的树脂制部件彼此接触的同时使这两个部件相对于彼此转动，以及借助于在这两个部件的接触区域中产生的摩擦热将这两个部件焊接在一起。然而，在通过旋转焊接来焊接树脂部件以制造产品时，需要采取措施来防止产品的外观由于摩擦热所产生的并流出到外部的熔融树脂而劣化、并且还防止瓶的特征由于进入瓶内部的熔融树脂而劣化。日本专利申请特开No.2018-84735描述了一种利用环形凹槽的部件的技术，作为容纳不必要地产生的熔融树脂的空间，该环形凹槽形成在外壳的开口周围以接收圆筒形盖，以便通过旋转焊接将盖结合至外壳。
然而，日本专利申请特开No.2018-84735的技术需要形成其中要插入盖的凹槽的操作，因此外壳必须设置有用于形成凹槽的空间，这进而限制了容器的设计自由度。
发明内容
本公开的一个方面是提供一种液体存储瓶，该液体存储瓶不会由于旋转焊接而导致外观和特征的劣化，并且也不会由于旋转焊接而导致设计自由度受到限制。

具体实施方式
下面将参考附图详细描述本公开的各种实施例、特征和方面。尽管下面将就用于用液体(墨水)再填充至液体喷射设备(喷墨记录设备)的例子来描述根据本公开的液体储存瓶，但是根据本公开的液体储存瓶的应用不限于这种例子。注意，在下面通过参考附图给出的整个说明书中，相同的部件由相同的附图标记指代，并且可能不会重复描述。
图1是其中采用根据本公开的液体存储瓶的示例性液体喷射设备的示意性透视图，示出了该示例性液体喷射设备的外观。
液体喷射设备1是串行型喷墨记录设备，其包括外壳11和布置在外壳11内部的四个大容量液体罐12(对应于图2中的12a、12b、12c、12d)。液体罐12用于容纳要喷射至记录介质(未示出)的液体(其为墨水)。
图2是图1的液体喷射设备1在外壳11被取出以使设备主体的内部结构可见的状态下的示意性透视图。
液体喷射设备1包括用于传送记录介质(未示出)的传送辊13、配备有用于喷射液体的记录头14的滑架15、和用于驱动滑架15的滑架马达16。尽管记录介质通常可以是纸张，但是记录介质绝不限于纸张，只要可以通过从记录头14喷射的液体(墨水)在记录介质上形成图像即可。记录介质随着传送辊13被间歇地驱动旋转而沿副扫描方向间歇地传送。随着滑架马达16被驱动旋转，滑架15被驱动以在与记录介质传送方向(即，副扫描方向)相交的主扫描方向上往复运动。随着在滑架15和记录头14的往复运动和扫描操作期间液体(墨水)从布置在记录头14中的喷射端口喷射至记录介质上，图像被记录在记录介质上。
液体(墨水)容纳在液体罐12中并通过液体流动路径(其包括布置在由图2中的虚线包围的区域中的各个液体供应管)供应至记录头14。采用四种颜色的墨水(例如，黑色墨水、青色墨水、品红色墨水和黄色墨水)作为液体，并且布置四个液体罐12a、12b、12c、12d作为液体罐12以分别存储四种颜色的墨水。四个液体罐12a至12d布置在液体喷射设备的前面侧并且布置在外壳11中。
图3是布置在图1的液体喷射设备1中的液体罐12之一的示意性透视图，示出了液体罐12的外观。
每个液体罐12包括用于存储液体(墨水)的罐体121、与罐体121内部的液体容纳腔连通的入口端口122、以及可以安装至罐体121上以覆盖入口端口122的罐盖123。在将罐盖123从罐体121移除由此以露出入口端口122之后，每个液体罐122可以再填充液体(墨水)。在液体罐被再填充液体(墨水)之后，罐盖123被放回至罐体121上，以使墨水从罐体121内部的液体容纳腔中的蒸发最小化。
图4是根据本公开的液体存储瓶2的一个实施例的示意性透视图，示出了液体存储瓶的外观。图5是图4的液体存储瓶2的分解的示意性透视图，示出了在组装液体存储瓶2的各部件以制造液体存储瓶2之前液体存储瓶2的各部件的外观。
液体存储瓶2是用于用液体(墨水)再填充液体罐12之一的液体(墨水)容器，并且包括用于容纳液体的圆筒形瓶体21(瓶体的相对两端中的一端是开口的)、管嘴22和盖23。管嘴22连接并牢固地固定至瓶体21的开口端，并且具有通过其倒出储存在瓶体21中的液体(墨水)的功能。如后文将描述的，盖23被可移除地安放至管嘴上以关闭和打开管嘴22的出口端口22b，并且具有相对于外部空气屏蔽瓶体21的内部并气密地密封液体存储瓶2的功能。瓶体21和管嘴22这两者均为树脂部件，并且管嘴22通过焊接而结合并牢固地保持至瓶体21上，以防止在将管嘴22和瓶体21结合至彼此之后液体存储瓶2中的液体通过树脂部件的界面泄漏。
瓶体21的开口端被形成为圆筒形瓶体的瓶体侧待被焊接部24，管嘴22的面向瓶的瓶体侧待被焊接部24的一侧被形成为圆筒形管嘴的管嘴侧待被焊接部25。管嘴22的管嘴侧待被焊接部25的内周面与瓶体21的瓶体侧待被焊接部24的外周面接触。随着这两个面通过焊接而结合至彼此，管嘴22变为被焊接并牢固地结合至瓶体21。对于本实施例的焊接和结合操作，采用旋转焊接技术。管嘴22在其中心部分处具有管嘴侧接合部22a，并且在其前端处具有用于倒出液体(墨水)的出口端口22b。盖23具有盖侧接合部23a，并且随着盖侧接合部23a变为与管嘴侧接合部22a接合，盖23被安装至管嘴22上。使用盖23的目的是使在容器无意掉落或以其他方式受到冲击时液体散落和损坏液体存储容器的任何部件的风险最小化。因此，只要实现使用盖的上述目的，盖23如何安放在管嘴22上的方式就不受任何特定的限制。在将盖23牢固地安放在管嘴22上的示例性技术中，在管嘴侧接合部22a的外周面上切出公螺纹以使管嘴作为螺杆操作，同时在盖侧接合部23a的内周面上切出母螺纹以使盖作为螺母操作，并且盖被拧到管嘴上。
注意，瓶体侧待被焊接部24设置有下文将更详细地描述的凹槽26。
图6是沿着图5中的线6-6截取的图4的液体存储瓶的分解的示意性剖视透视图，示出了瓶体和管嘴如何通过旋转焊接而结合至彼此。
如上所指出的，瓶体21和管嘴22通过旋转焊接而彼此结合。更具体地，在瓶体侧待被焊接部(第一圆筒部)24的外周面24a与管嘴侧待被焊接部(第二圆筒部)25的内周面25a保持彼此接触的同时，驱动瓶体21和管嘴22相对于彼此旋转，并且将瓶体侧待被焊接部24插入至管嘴侧待被焊接部25中以使它们彼此牢固地接合。此时，在瓶体侧待被焊接部24的外周面24a与管嘴侧待被焊接部25的内周面25a之间产生摩擦热，并利用所产生的摩擦热来使瓶体侧待被焊接部24的外周面24a的树脂与管嘴侧待被焊接部25的内周面25a的树脂熔融。于是，结果是瓶体21和管嘴22被焊接并结合至彼此。
图7A和7B是本实施例的液体存储瓶的一部分的放大的示意性剖视图，依次示出了瓶体和管嘴如何通过旋转焊接结合至彼此。图7A示意性地示出了正被焊接至彼此的瓶体和管嘴，图7B示意性地示出了已经焊接至彼此的瓶体和管嘴。
随着瓶体侧待被焊接部24被插入至管嘴侧待被焊接部25中，在驱动瓶体21和管嘴22相对于彼此旋转的同时，在瓶体侧待被焊接部24的外周面24a与管嘴侧待被焊接部25的内周面25a之间产生了摩擦热，使得外周面24a的树脂材料和内周面25a的树脂材料都变得熔融(树脂材料的熔融部分在图7A中用M表示)。瓶体侧待被焊接部24具有从外周面24a的轴向端部(基部)向外侧径向地且连续地延伸的第一接触面24b，同时管嘴侧待被焊接部25具有从内周面25a的相应轴向端部(基部)向外侧径向且连续地延伸的第二接触面25b。这样，瓶体侧待被焊接部24被插入至管嘴侧待被焊接部25中，直到第一接触面24b与第二接触面25b接触。随着第一接触面24b和第二接触面25b变得彼此接触，焊接操作结束并且瓶体21和管嘴22在它们的接触面处熔融并结合至彼此，从而完成了制造液体存储瓶2的过程。
在上述焊接过程中，随着执行将瓶体侧待被焊接部24插入至管嘴侧待被焊接部25中的操作，瓶体的树脂材料和管嘴的树脂材料部分地熔融，并且树脂材料的熔融树脂3通过接触面25b而被推出至瓶体侧待被焊接部24的外周面24a上。注意，熔融树脂3的量可能变化，这是因为模制的液体存储瓶的尺寸和用于通过模制形成液体存储瓶的模制步骤这两者都会牵涉变化(即使只是很小的程度)。在一些情况下，熔融树脂会被推出至液体存储瓶2的外部。鉴于上述问题，在本实施例中，沿周向方向延伸的环形凹槽26形成在瓶体侧待被焊接部24的外周面24a上，以容纳过多地产生的熔融树脂3并使向外部推出的熔融树脂3的量最小化。由于在焊接过程中瓶体21和管嘴22被驱动以相对于彼此旋转，因此具有粘弹性的熔融树脂3和其他异物(如果有的话)最终到达凹槽26，同时所述熔融树脂3和其他异物在周向方向上受到剪切应力，并且由于剪切应力所产生的张力而变为卷绕至凹槽26的内部。这样，在焊接过程中产生的包括熔融树脂3的异物(为方便起见，在下文中简称为熔融树脂3)可以被有效地捕集在凹槽26中，以使被推出至液体存储瓶2的外部的熔融树脂3的量最小化。
在焊接过程结束时，凹槽26面对管嘴侧待被焊接部(其现已成为被焊接部)25的内周面25a，因此完全被管嘴侧被焊接部25覆盖。因此，瓶体侧待被焊接部24设置凹槽26的净效果不仅在于能够可靠地防止在焊接过程中产生的熔融树脂3被推出至外部，而且还在于可以防止产品的适宜外观受到不希望的损坏。另外，在本实施例中，由于仅仅瓶体侧待被焊接部24的外周面24a设置凹槽26便足够(尽管存在两个要焊接至彼此的周面，包括瓶体侧待被焊接部24的外周面24a和管嘴侧待被焊接部25的内周面25a)并且瓶体侧待被焊接部24的外周面24a相对于管嘴侧待被焊接部25的内周面25b位于内周侧，因此本实施例的液体存储瓶的设计自由度不会由于设置这种凹槽26而降低。
凹槽26优选在靠近直接连接至第一接触面24b的轴向端部(基部)的位置处布置在瓶体侧待被焊接部24的外周面24a上。当在这种位置处形成凹槽26时，被推出的熔融树脂3能够可靠地且有效地收集在凹槽26中，以使得被推出至外部的熔融树脂3的量最小化。在图7A和7B所示的布置中，在凹槽26的下方瓶体侧待被焊接部24的外周面24a和管嘴侧待被焊接部25的内周面25a也结合至彼此，但是外周面24a与内周面25a的位于凹槽26下方的接触区域非常小，因此仅仅在非常小的程度上会在该接触区域中产生熔融树脂3。如果在该接触区域中产生熔融树脂3，则可能被推出至液体储存瓶2外部的熔融树脂3被第一接触面24b和第二接触面25b阻挡，并且实际上不会被推出至外部。
注意，从使阻挡倾向于被推出至液体存储瓶2外部的熔融树脂3的效果最大化的角度来看，第一接触面24b优选相对于瓶体侧待被焊接部24的外周面24a垂直地延伸，相应地第二接触面25b也优选相对于管嘴侧待被焊接部25的内周面25a垂直地延伸。第一接触面24b的位置和第二接触面25b的位置不受任何特别的限制，只要使第一接触面24b与第二接触面25b彼此接触以适当地对准瓶体21和管嘴22即可。然而，为了突出地实现阻挡要不然可能被推出至液体存储瓶2外部的熔融树脂3的效果，第一接触面24b优选连接至瓶体侧待被焊接部24的外周面24a并且使第一接触面24b从外周面24a径向向外地延伸，如本实施例中一样。因此，相应地，第二接触面25b优选连接至管嘴侧待被焊接部25的内周面25a并使第二接触面25b从内周面25a径向向外地延伸。
在图7A和7B所示的布置中，在第一接触面24b和第二接触面25b彼此接触时，第一接触面24b和第二接触面25b可能尚未焊接至彼此但焊接操作可能停止。替代地，可以在第一接触面24b和第二接触面25b彼此接触之后继续进行焊接操作，直到第一接触面24b和第二接触面25b可靠地焊接至彼此为止。如果在第一接触面24b和第二接触面25b彼此接触之后继续进行焊接操作直到第一接触面24b和第二接触面25b焊接至彼此，则应注意不使产生的熔融树脂3推出至液体存储瓶2的外部。另一方面，如果在第一接触面24b与第二接触面25b彼此接触时第一接触面24b和第二接触面25b尚未焊接至彼此但焊接操作停止，并且另外如果在凹槽26中不仅发现了熔融树脂3、而且还发现了空气，则即使在凹槽内的空气膨胀时也不会产生问题而引起意想不到的不利影响，因为存在关于空气的逃逸路径。
尽管未示出，但是优选地，凹槽26布置在其中外周面24a连续地延伸以产生第一接触面24b的位置处。于是，在凹槽26的下方没有发现存在熔融树脂3的区域。换句话说，在凹槽26的下方不会产生熔融树脂3，从而不会出现任何意想不到且难以控制的麻烦。另外，捕获在凹槽中的空气能够容易地逃逸至外部。
图8A和8B示意性地示出了通过改变图7A和7B中所示的瓶体和管嘴而获得的两组不同的瓶体和管嘴。
如图8A所示，第一接触面24b可以包括轴向突出部29a，该轴向突出部分29a是相对于第一接触面24b布置在径向外侧处并沿轴向方向突出的圆筒部。由于焊接瓶体侧待被焊接部24与管嘴侧待被焊接部25的焊接过程继续进行直到第一接触面24b与第二接触面25b彼此接触，所以即使从接触面24b、25b产生的熔融树脂也不能忽略不计。然而，如果从第一接触面24b和第二接触面25b产生熔融树脂，则能够通过突出部29a防止熔融树脂露出至外部，因此能够使液体储存瓶2的外观保持可接受。注意，这种突出部29a可以设置在瓶体侧待被焊接部24上或管嘴侧待被焊接部25上。换句话说，突出部29a可以替代地设置在瓶体侧待被焊接部25上，如图8B所示。另外，在瓶体侧待被焊接部24和管嘴侧待被焊接部25中的任一者设置有突出部29a的情况下，瓶体侧待被焊接部24和管嘴侧待被焊接部25中的另一者可以设置有用于接收突出部29a的环形凹部29b，以用于维持液体储存瓶2的平滑外观。包括突出部29a的厚度的轮廓不受任何特定的限制，只要突出部29a紧贴地并令人满意地覆盖第一接触面24b和第二接触面26b并使它们从外部不可见即可。
凹槽26设置的目的是收集可能过量地产生的熔融树脂3，因此除了熔融树脂3之外还可以收集空气。考虑到该潜在问题，优选使凹槽26具有从第一接触面24b连续地延伸的侧面，如图8A和8B所示。在这种布置中，在瓶体侧被焊接部24与管嘴侧被焊接部25的焊接界面上不残留空气，因此能够将第一接触面24b和第二接触面25b更牢固地焊接至彼此。
因此，根据上述本公开，提供了不存在外观和功能的劣化并且也不存在设计自由度的限制的液体存储瓶、以及制造液体存储瓶的方法。
尽管已经参考示例性实施例描述了本公开，但是应当理解，本公开不限于所公开的示例性实施例。所附权利要求的范围应被赋予最宽泛的解释，以涵盖所有这种修改和等同的结构及功能。
