Production method of hermetically sealed container for drink or food

Object of the present invention is to provide a manufacturing method sealed container, so that the use of laser welding for beverages or food containers are sealed, it is possible to improve the sealing step of processing speed, without strictly controlling the scanning position of the laser spot and difficult to produce locally excess supply of energy, in addition, does not produce a bonding area is reduced due to the aggregation of molten droplets caused by melting and bonding strength of each area. Beverages or food according to the present invention, a method of manufacturing a sealed container by a laser welding method and the container body is mounted on the mouth portion of the container body cap melt bonding becomes airtight, characterized in that the beverage or food a method of producing a container having a sealed simultaneously or substantially simultaneously joined by melt bonding said container body and said lid portion to be welded throughout the process.
