Description

密封容器及其制造方法
技术领域
本发明涉及密封容器，其能够密封良好地封入食品饮料等内容物并且在接触感良好的饮用口处使液体滴落少，特别涉及具有被激光焊接的焊接部的密封容器及其制造方法。
背景技术
对于密封容器，例如在饮料用容器中已知有瓶、罐、塑料容器等各种容器。近年来，从处理性优良等便利性观点出发而广泛使用罐和塑料容器。其中罐由于容器价格低、生产速度快、输送效率高等原因而更加广为流通。该罐通常由做成有底圆筒形的“筒部”和封闭筒部的开口部的“盖部”构成。由于需要使该筒部和盖部适当接合来对食品饮料等内容物进行密封，罐通常为铝或钢等金属制的。
该筒部和盖部的接合，通过使筒部的端部和盖部的端部重叠而形成凸缘结构并通过机械重叠卷接来进行。该卷接工序利用金属部件的机械变形，因此盖部通常由比筒部厚的部件构成，并且为了密封内容物而具有苯乙烯-丁二烯橡胶或聚氯乙烯等聚合物材料。因而，聚合物材料是必需的，而且金属材料的使用量增多。
因此，为了解决该问题提出了以金属罐为对象通过激光焊接来进行罐的密封的技术(例如参照专利文献1～3)。
但是，对于塑料制饮料容器实施卷接工序是困难的，因此塑料制的饮料用罐容器没有流通。在塑料制饮料容器中，最流通的容器是PET(聚对苯二甲酸乙二醇酯)瓶。在PET瓶上，使用在瓶口部旋合盖子的方式作为密封方式。但是，该盖子在容器整体中，成为成本大大上升的重要因素。并且由于盖子主要为PP(聚丙烯)制，所以成为回收的障碍。
专利文献1：WO02/42196A2号公报
专利文献2：日本特开昭63-194885号公报
专利文献3：日本特开昭61-289932号公报
如果在对金属制的罐进行密封时使用卷接方法，则聚合物材料的使用和卷接部分的罐材料的余量都是必须的，从而成为成本上升的重要原因。以专利文献1为代表的激光焊接的罐容器，就是以减少材料的使用量和省去聚合物材料为目的进行研究，试验激光焊接以便取代现有的卷接，但是由于未能超越卷接方式而没有实用化。
另外，以专利文献1为代表的激光焊接的罐容器，虽然不卷接，但是仍然形成凸缘，由于该凸缘而不利于饮用，并助长液体滴落。因而仍未解决凸缘造成的缺点。
发明内容
本发明目的在于，使密封容器中被激光焊接的焊接部不形成凸缘的结构，从而获得在接触感良好的饮用口处液体难以滴落的容器，进而能够达成省去聚合物材料以及卷接部分的余量材料。此时，由于采取不形成凸缘的结构，从而能够实现盖自身的小型化。另外，当密封容器为塑料容器时，与现有的PET瓶相比，能够提高填充速度和输送效率并且提高容器的回收性。此时，由于塑料容器具有透光性，所以使密封容器与金属罐不同，能够看到内容物。
本发明人为了省去聚合物材料并且减少使用卷接部分的余量材料而进行了锐意研究，结果发现，通过设置不形成卷接部分那样的凸缘的被激光焊接的焊接部就能解决所述问题，从而完成了本发明。即，本发明的密封容器，其具有开口部的容器主体由封闭所述开口部的盖部进行密封，其特征在于，具有：以所述容器主体的内壁面中至少所述开口部的周缘部分的内壁面可与容器内容物接触的方式，激光焊接所述开口部的周缘部分的外壁面和所述盖部的内壁面的焊接部。另外，本发明的另一方式的密封容器，其具有开口部的容器主体由封闭所述开口部的盖部进行密封，其特征在于，具有：以所述容器主体的内壁面中至少所述开口部的周缘部分的内壁面可与容器内容物接触的方式，激光焊接所述开口部的端面和所述盖部的内壁面的焊接部。这里所述焊接部包括不形成凸缘的情况。如果使本发明的这些密封容器的被激光焊接的焊接部成为不形成凸缘的结构，则在接触感良好的饮用口处使液体难以滴落。并且既不需要聚合物材料，又由于没有卷接部分也不需要余量的材料。能够使盖自身小型化。
在本发明的密封容器中，包括具有所述盖部的周缘部分的内壁面不与所述容器主体的外壁面进行焊接的非焊接部的情况。在焊接部位是开盖部位时，该非焊接部成为手指的勾挂部分或者把手，从而提高开盖性。
在本发明的密封容器中，包括所述盖部壁厚为0.2mm以上的情况。如果取盖部的壁厚为0.2mm以上来赋予刚性，则即使在对填充碳酸饮料等的容器施加内压的情况下，也能够作为密封容器加以利用而不会破裂。与热密封工艺不同，激光焊接工艺即使取盖部的壁厚为0.2mm以上时也能够进行焊接。
在本发明的密封容器中，包括所述焊接部沿着所述开口部的周缘激光焊接为两个以上的循环线状的情况。焊接部可以焊接接合面的整个面，但是通过激光焊接成两个以上的循环线状，能够平衡良好地确保接合强度、密封性和易开盖性。
在本发明的密封容器中，包括这样的情况：所述盖部具有在内壁面侧接合了环状层的多层结构，该环状层具有与所述开口部的开口直径大致相同的内径，并且，在保持所述环状层被激光焊接在所述容器主体上的状态下，通过使所述盖部从所述环状层剥离，使容器开封。通过将盖部对容器主体的焊接部分和开盖时的剥离部分分开，从而能够同时赋予高密封性和易开盖性。
在本发明的密封容器中，优选所述容器主体和所述盖部由合成树脂形成。能够提高填充速度和输送效率以及容器的回收性。并且能够看到容器内容物。
在本发明的密封容器中，包括所述容器为饮料用容器的情况。
本发明的密封容器的制造方法，用于制造具有开口部的容器主体由封闭所述开口部的盖部进行密封的密封容器，其特征在于，具有：以所述容器主体的内壁面中至少所述开口部的周缘部分的内壁面可与容器内容物接触的方式，在所述开口部的周缘部分的外壁面和所述盖部的内壁面密接而形成密接面后，对该密接面照射激光来形成焊接部的工序。另外，本发明另一方式的密封容器的制造方法，用于制造具有开口部的容器主体由封闭所述开口部的盖部进行密封的密封容器，其特征在于，具有：以所述容器主体的内壁面中至少所述开口部的周缘部分的内壁面可与容器内容物接触的方式，在所述开口部的端面和所述盖部的内壁面密接而形成密接面后，对该密接面照射激光来形成焊接部的工序。由于具有这样的工序，仅通过对接合面照射激光就能够接合，因此非常简易，并且在作为接合部位的焊接部上不形成凸缘。
本发明的密封容器的制造方法，优选具有：在所述开口部的周缘部分的外壁面或所述盖部的内壁面中的至少任何一方或者所述开口部的端面或所述盖部的内壁面的至少任何一方上设置激光的吸收部的工序。特别优选对不吸收激光的透明的塑料进行激光焊接的情况或对不是透明的塑料也没有对激光波长的吸收频带的塑料进行焊接的情况。激光通常具有仅能够对微小区域进行照射的特性。通过在接合部分上设置吸收部，能够仅对该部分作用激光。即，与卷接和热密封不同，通过适当地移动激光的照射位置，即使是具有机械接触复杂的轮廓和起伏，也能够容易且高精度地进行非接触溶接和密封。
本发明的密封容器的制造方法，优选在所述开口部的周缘部分的外壁面或所述盖部的内壁面的至少任何一方的部位或者所述开口部的端面或所述盖部的内壁面的至少任何一方的部位上含有激光的吸收材料。能够与上述吸收部同样地使激光作用于含有吸收材料的部位。因此，与卷接和热密封不同，通过适当地移动激光的照射位置，即使在具有机械接触复杂的轮廓和起伏的情况下，也能够容易且高精度地进行非接触熔接和密封。
在本发明的密封容器的制造方法中，优选使对所述焊接部的激光照射在使激光振荡元件固定并使所述容器主体和所述盖部以容器中心轴为自转轴自转的情况下进行，或者在使激光振荡元件以容器中心轴为旋转轴绕所述容器主体和所述盖部旋转的情况下进行。能够进行精度良好的激光焊接。
本发明的密封容器由于被激光焊接的焊接部不形成凸缘，所以没有因凸缘导致的凹凸形状，饮用口的接触感良好，液体难以滴落。在金属罐中可以不必使用聚合物材料或凸缘部分的余量材料。另外能够使盖自身小型化。另外，如果使密封容器为塑料容器，则由于不必要旋合式的盖，所以而能够提高填充速度和输送效率，并且能够使容器主体和盖部为相同材料，因此能够提高容器的回收性。此时，由于具有透光性，所以能够与玻璃瓶同样地看到容器内容物。另外，按照本发明的密封容器的制造方法，仅对接合面照射激光就能够接合，因此非常简易，并且在接合部位不形成凸缘。

具体实施方式
下面针对本发明示出实施方式并详细地进行说明，但本发明不能被解释为限定于这些叙述。首先参照图1～3对本实施方式的密封容器进行说明。另外对同一部件/同一部位标以相同标号。
图1(a)表示本实施方式的第一方式的密封容器的局部纵剖面简图。第一方式的密封容器100，其具有开口部9的容器主体1由封闭开口部9的盖部3进行密封，其特征在于，具有：以容器主体1的内壁面中至少开口部9的周缘部分的内壁面6可与容器内容物接触的方式，激光焊接开口部9的周缘部分2的外壁面和盖部3的内壁面的焊接部4。
图1(b)表示本实施方式第二方式的密封容器的局部纵剖面简图。第二方式的密封容器200，其具有开口部19的容器主体11由封闭开口部19的盖部13进行密封，其特征在于，具有：以容器主体11的内壁面中至少开口部19的周缘部分的内壁面16可与容器内容物接触的方式，激光焊接开口部19的端面12和盖部13的内壁面的焊接部14。
在第一方式的密封容器和第二方式的密封容器中，除了容器主体上的激光焊接部位不同以外具有相同的结构。第一方式的密封容器将焊接部4的面积取得较大，因而可以使耐压强度增大。
容器主体1、11和盖部3、13只要是能够进行激光焊接的材料，则也可以由以下的材料形成，但是也受到容器内容物的限制。例如，如果是饮料用容器，则从保持内容物的质量的观点出发，需要相对于容器内容物为非活性材料。进而优选具有氧气等的阻气性的材料。另外在填充碳酸饮料的情况下需要由具有耐压性的材料形成。从这样的观点出发，优选容器主体1、11和盖部3、13由铝或钢等金属材料或者塑料材料形成。容器主体1、11和盖部3、13从回收性观点出发优选以相同材料形成。特别是优选由塑料材料形成，采用激光焊接，即使不加热到高温也能够进行焊接。如果是激光焊接成的塑料制的密封容器，与现有的PET瓶相比，能够在提高填充速度和输送效率的同时提高容器的回收性。此时，由于塑料容器具有透光性，所以与金属罐不同，能够看到容器内容物。另外若对罐结构进行比较，则即使是不能够卷接的形状也能够进行密封，与卷接的情况相比能够使用较小的盖进行密封。
在成形本发明的塑料容器时使用的树脂例如是：聚对苯二甲酸乙酯树脂(PET)、聚对苯二甲酸丁酯树脂、聚对苯二甲酸萘酯树脂、聚乙烯树脂、聚丙烯树脂(PP)、环烯烃共聚物树脂(COC、环状烯烃共聚)、离聚物树脂、聚-4-甲基戊烯-1树脂、聚甲基丙烯酸甲酯树脂、聚苯乙烯树脂、乙烯-乙烯醇共聚树脂、丙烯腈树脂、聚氯乙烯树脂、聚偏二氯乙烯树脂、聚酰胺树脂、聚酰亚胺树脂、聚甲醛树脂、聚碳酸酯树脂、聚砜树脂，或者，四氟乙烯树脂、丙烯腈-苯乙烯树脂、丙烯腈-丁二烯-苯乙烯树脂等。其中特别优选PET。另外，当容器主体1、11和盖部3、13为塑料制时，也可以使用在其内表面或外表面或者其两面上涂布DLC(类金刚石碳)膜、含硅DLC膜、类聚合物碳膜、SiOX膜等阻气性薄膜。这是因为，在饮料用塑料容器的情况下优选阻气性高者。另外，在阻气性薄膜吸收激光的情况下，激光的受光部会发热。因此，即使由不吸收激光的透明树脂形成容器，通过形成阻气性薄膜而即使不另设吸收部，焊接效率也良好。
在第一方式的密封容器和第二方式的密封容器中，(1)内壁面6、16可与容器内容物接触，以及(2)开口部9的周缘部分2的外壁面或者开口部19的端面12任何一方与盖部3的内壁面接合，从而使焊接部4、14不形成凸缘。另外，接合部分仅通过使容器主体和盖部重叠成平面状来进行焊接，因此能够使盖自身小型化。另外，在本发明中，将盖部可与容器内容物接触的面标记为盖部的内壁面。
只要满足上述接合结构，盖部的形状和容器主体的形状，特别是开口部形状可以适当变更。在第一方式的密封容器100中，容器主体1具有使其壁朝向容器内部折返的形状，开口部9形成于比其折返部的高度低的位置。通过使容器主体1具有这样的形状，就成为在开盖时使吸管易于***开口部9的形状。盖部3至少具有能够覆盖开口部9的大小以密封开口部9，同时形成为沿着包围开口部9的容器主体1的外壁面的形状。由此，形成作为焊接部4的接合部分的密接面。
为了防止容器内容物的滞留，优选把容器主体1、11的开口部9、19的外缘部分激光焊接成直到周缘部分2、12。
另一方面，在第一方式的密封容器和第二方式的密封容器中，也可以具有盖部3、13的周缘部分的内壁面不与容器主体1、11的外壁面焊接的非焊接部5、15。在图1(a)和(b)中，将未焊接部5、15作为开封把手。通过设置非焊接部5、15，在将焊接部位作为开盖部位的情况下，在开盖时易于将手指勾挂于非焊接部5、15，可以赋予易开盖性。
另外，在本实施方式的密封容器中，除了使焊接部4、14剥离来进行开盖的类型的容器之外，也包括不使焊接部4、14剥离而通过拉环等开启装置对例如与开口部9、19分开设置在盖部上的按压漏斗解除密封的类型的容器。
盖部3、13优选壁厚为0.2mm以上，更优选为0.3mm以上。在盖部3、13为不足0.2mm的薄片的情况下，能够通过热密封工艺使容器主体和盖部熔融接合，即使不对焊接部4、14进行激光焊接也能够应对。但是，在盖部3、13的壁厚为0.2mm以上的情况下则难以使用热密封工艺，另外当接合面形状为复杂的形状时，则其难以使用热密封工艺。与此相对，对于塑料等透明的材料采用激光焊接工艺，只要不吸收激光就不会发热。因此，即使盖部3、13的壁厚为0.2mm以上也能够进行激光焊接。在盖部3、13的壁厚为0.2mm以上的情况下能够对盖部自身赋予刚性，因此能够提高密封容器的强度，特别是能够提高耐压性。另外，为了获得刚性，容器主体1、11的壁厚优选为0.2mm以上。
下面在图1(c)中表示本实施方式的第三方式的密封容器的局部纵剖面简图。第三方式的密封容器300在盖部23的端部设置用于开盖的把手27。从容器主体21一直到开口部29成为截头圆锥状，从而形成易于饮用的饮用口。另外，能够使盖部小型化而减少盖材料的使用量。
下面在图2中表示本实施方式的第四方式的密封容器的局部纵剖面简图。第四方式的密封容器400使焊接部34沿着开口部39的周缘被激光焊接为两个循环线状。焊接部也可以被焊接成整个接合面，但是通过激光焊接为两个循环线状，对于接合强度和密封性而言，与整个面焊接的情况同等，并且能够提高易开盖性。当然，也可以将焊接部34激光焊接为三个以上的循环线状。
另外，在本实施方式的密封容器中，为防止非焊接部在输送中摩擦造成开盖，所以也可以采用如图2所示的密封容器400那样的结构，在容器主体上设置台肩38来保护非焊接部35。另外，在设置台肩38的情况下，当手指难以勾挂非焊接部35时，为了使手指易于勾挂非焊接部35，也可以使非焊接部35的勾挂部分37离开与容器主体31接触的外壁面。
在第一至四方式的密封容器中，在剥离焊接部来进行开盖的情况下，通过在容器主体和盖部的接合面上进行剥离或者在容器主体的壁内部进行剥离或者在盖部的壁内部进行剥离。该剥离部位由于与设置激光吸收部的部位对应而能够进行控制。在将剥离部位作为饮用口的端部的情况下，从使接触感觉良好的观点出发，优选在容器主体和盖部的接合面上进行剥离或者在盖部的壁内部进行剥离。
下面在图3中表示本实施方式的第五方式的密封容器的简图。(a)为侧面图，(b)为使(a)旋转90度时的局部纵剖面简图，(c)为开盖时的局部纵剖面简图。第五方式的密封容器500具有多层结构，在该多层结构中，具有与开口部49的开口直径大致相同的内径的环状层50接合在盖部43的内壁侧上。环状层50和容器主体41的接合面被激光焊接而形成焊接部44。另外，如图3(c)所示，在保持环状层50激光焊接于容器主体41上的状态下，使盖部43从环状层50剥离，从而打开容器。设置于盖部43的端部的把手47是使手指易于勾挂的结构，台肩48用于防止在容器输送中由于摩擦而对把手47的勾挂。在第五方式的密封容器中，通过使盖部43向容器主体41上的焊接部分和开盖时的剥离部分分开而能够同时赋予高密封性和易开盖性。
在第一至第五方式的密封容器中，焊接部没有凸缘。另外在第一至第四方式的密封容器中，能够提供在剥离焊接部后具有良好接触感觉的饮用口。另外，也不会在凸缘附近附着容器内容物，液体滴落少。另外，由于可以使盖部小型化而能够减小盖面积，从而减小在注入了碳酸饮料等内容物时施加于盖部整体的总压力(来自内侧的压力)，提高耐压性。
下面参照图4和图5对本实施方式的密封容器的制造方法进行说明。首先，对图4所示工序(第一制造方式)进行说明。首先在步骤S1中，将内容物填充完毕的容器主体61由传送器等搬运装置(未图示)导入激光焊接机。此时，在内容物起泡的情况下进行除泡，实施碳酸气清除或氮气清除。
接下来在步骤S2中，由盖部搬运装置63a将盖部62搬运至盖部供给装置63b。盖部供给装置63b将一个盖部62供给至一个容器主体61的开口部。
下面在步骤S3中，盖部配置装置64使盖部62与容器主体61的开口部重叠而形成作为接合面的密接面，并且施加适度压力以避免盖部62与容器主体61错开。例如为了使盖部与容器主体密接而用棒状部件从盖部的上方按压盖部。通过对盖部的按压而间接地压住容器主体。使用压力传感器检测棒状部件的按压。压力传感器可以是盖部检测用的近接传感器，但是通常塑料对磁性的近接传感器的灵敏度不良。因此，优选压力传感器或者激光位移计。优选在盖部配置装置64中加入压力传感器或者激光位移计的检测值，该压力传感器或者激光位移计对盖部62被按压入容器主体61的开口部的压力进行检测。
下面在步骤S4中，将保持配合了盖部62的容器主体61载置于转台69上。转台69上的各容器主体61及其盖部62，因以容器为轴中心自转的自转台68而进行自转。此时，由激光发生装置65对容器主体61与盖部62的密接部分66照射激光。激光可以示例出点状、线状或者环状形式照射。根据激光发生装置65与密接部分66的位置关系来适当选择激光照射形状。此时，激光强度优选通过检查对激光功率进行监视。另外，激光的点位置优选由感光传感器或者红外线传感器等温度传感器通过检查发光或者发热进行监视。塑料的焊接优选由感光传感器或者红外线传感器通过检查发光或者发热进行监视。也可以一并使用CCD等图像传感器。
装入激光发生装置65的激光振荡元件，例如是半导体激光器、二氧化碳气体激光器等气体激光器、YAG激光器，根据进行激光焊接的容器主体和盖的材质、激光照射移动速度、照射点形状等各种参数进行适当选择。在对塑料容器进行激光焊接的情况下优选半导体激光器(例如功率1W～100W)。
在制造第一实施方式的密封容器100时，以容器主体的内壁面中至少开口部的周缘部分的内壁面可与容器内容物接触的方式，在开口部的周缘部分的外壁面和盖部的内壁面密接而形成密接面后，对密接面照射激光来形成焊接部。
另一方面，在制造第二实施方式的密封容器200时，以容器主体的内壁面中至少开口部的周缘部分的内壁面可与容器内容物接触的方式，在开口部的端面和盖部的内壁面密接而形成密接面后，对密接面照射激光来形成焊接部。
这里，优选具有：在开口部的周缘部分的外壁面或盖部的内壁面的至少任何一方或者开口部的端面和盖部的内壁面的至少任何一方上设置激光的吸收部的工序。即使对于沿着吸收部的机械接触是复杂的轮廓和起伏，也能够进行精度良好的激光焊接。能够收缩激光的照射点，主要对设置吸收部的位置进行焊接。吸收部可以通过将吸收激光的波长的有机颜料或无机颜料等吸收物质附着于所需的接合部位来进行着色等任何方法形成。优选根据吸收部对激光的吸收程度，对激光的波长、激光功率、激光扫描速度进行调整。该工序如果是在激光照射前则可以在任何时间进行，可以设置于步骤S1之前、或在步骤S1、步骤S2、步骤S3和步骤S4中的任一步骤。该工序在焊接对激光不具有吸收频带的材料时有效，所以并非必需工序。
另外，也可以在开口部的周缘部分的外壁面或盖部的内壁面中至少任何一方的部位或者开口部的端面或盖部的内壁面中至少一方的部位中含有激光的吸收材料。该工序如果是在激光照射前，则可以在任何时间进行，可以设置于步骤S1之前、或在步骤S1、步骤S2、步骤S3和步骤S4中的任一步骤。例如在成形盖部和/或容器主体时含有着色颜料等激光吸收材料。另外，该工序由于在焊接对激光不具有吸收频带的材料时有效，所以在对用混合颜料等进行着色的彩色容器进行激光焊接的场合等材料吸收激光的情况下并非必需工序。能够像一部分彩色瓶那样仅在接合部分吸收激光的情况下照射激光来进行激光焊接。另外，优选根据着色颜料等激光吸收材料的含有量，对激光的波长、激光功率、激光扫描速度进行调整。
由于容器主体61和盖部62因自转台68进行自转，所以激光器的照射部分沿着容器主体61的开口部移动，旋转一圈后完成密封。焊接速度决定于所需的焊接形状和材质等，例如为8～50cm/秒。此时，用激光焊接能够准确地控制焊接部位。另外，激光的输出和波长能够决定熔接的程度，比热密封和超声波焊接精度更高地形成焊接部。
另外也可以进行两圈以上的激光照射。通过使激光点通过数次，或者如图2所示那样具有多个接合部位，能够可靠地进行焊接。另外，也可以通过设置两个以上的激光振荡元件进行一圈照射，从而进行两个以上的循环线状的激光焊接。
下面在步骤S5中，将经激光焊接结束而完成密封的密封容器从转台69取下。
下面在步骤S6中，由不合格容器排除装置70排除密封不合格的容器。密封不合格的判断优选根据上述检查的结果和图像检查机(未图示)的外观检查结果来进行。
下面对图5所示的工序(第二制造方式)进行说明。由于在图4所示的工序和图5所示的工序中步骤S4不同，所以对步骤S4进行说明。
在步骤S4中，将保持配合了盖部62的容器主体61载置于转台69上。转台69上的各容器主体61及其盖部62在转台上静止。此时由激光发生装置65对容器主体61和盖部62的密接部分66照射激光。激光例如照射为点状、线状或环状。根据激光发生装置65与密接部分66的位置关系适当地选择激光照射形状。此时激光强度优选通过检查激光输出进行监视。另外，激光的点位置与图4的工序中说明的情况同样地优选通过检查进行监视。塑料的焊接也与图4的工序中说明的情况同样地通过检查进行监视。也可以一并使用CCD等图像传感器。
装入激光发生装置65的激光振荡元件可以使用与图4的工序中说明的相同的振荡元件。
在制造第一实施方式的密封容器100时，以容器主体的内壁面中至少开口部的周缘部分的内壁面可与容器内容物接触的方式，在开口部的周缘部分的外壁面与盖部的内壁面密接而形成密接面后，对密接面照射激光而形成焊接部。
另外，在制造第二实施方式的密封容器200时，以容器主体的内壁面中至少开口部的周缘部分的内壁面可与容器内容物接触的方式，在开口部的端面与盖部的内壁面密接而形成密接面后，对密接面照射激光而形成焊接部。
这里，可以与图4中说明的工序同样地设有设置激光的吸收部的工序和/或使其含有激光的吸收材料的工序。
激光发生装置65通过激光发生器旋转装置67以容器主体61和盖部62为中心旋转，因此能够使激光器的照射部分沿着容器主体61的开口部移动，通过激光发生器旋转装置67使激光发生装置65绕完一周而完成密封。焊接速度决定于所需接合的形状和材质等，例如为8～50cm/秒。此时，用激光焊接能够准确地控制焊接部位。
另外与图4的情况同样，也可以进行两圈以上的激光照射。通过使激光点通过数次，或者如图2所示那样具有多个接合部位，能够可靠地进行焊接。另外也可以通过设置两个以上的激光振荡元件进行一圈照射，从而进行两个以上的循环线状的激光焊接。
在图5所示的工序中，激光振荡元件为绕容器旋转的旋转式，因此能够进行高速运转和对多个接合部位进行激光焊接(同时定时或分别定时，对相同部位照射或对不同部位照射)。
在现有的金属罐的卷接工序中，难以通过实际进行卷接工序的时刻判断容器是否已适当密封。因此尽管制造开始前的检查结果良好，但在卷接工序中发生密封不合格的情况下，要在实际的不合格发生后经过相当的时间后才最终发现不合格。此时导致需要废弃的容器数量或者生产装置的停止时间大大增加。另一方面，根据本实施方式的图4或图5所示的密封容器的制造方法，能够在极短的时间内检测出焊接工序是否被恰当地实施，从而克服了金属罐的卷接工序的上述缺点。
