Latest Patents
Miyamoto's latest patents include a method of manufacturing containers for dispensing solutions. This method involves several steps: first, extruding a parison from a die while injecting supporting air into it and sealing the forward part of the extruded parison. Next, he forms a middle portion of the parison, which constitutes the barrel portion of the container, during extrusion, ensuring it has a wall thickness thinner than the forward part. After inserting the parison into a mold with a vacuum mechanism, air is injected to blow it out while maintaining a lower pressure inside the mold compared to the internal pressure of the parison. The parison is then cut off from the die to form a container. Following this, a mandrel is inserted into the molded container through a cut opening after transferring the mold to a solution-charging station, where a medical solution is charged into the container. Finally, the mandrel is pulled out after charging, and the opening of the solution-charged container is sealed.
