Method for producing medical glass container in which occurrence of cracking is reduced

Abstract

[Object] To provide a means manufacturing a medical glass container with less generation of a crack. [Solution] A method for manufacturing a medical glass container includes a first process of moving the tip of an ignited point burnerfrom a standby position where a flamedoes not contact a vialto a position where the tip of the ignited point burnerfaces an openingin the outside of the vial, a second process of inserting the tip of the point burnerinto an internal spaceof the vial, a third process of applying the flameto an inner surfaceof the vialwhile holding the tip of the point burnerin the internal space, a fourth process of moving the tip of the point burnerto the outside from the internal space, and a fifth process of moving the tip of the point burnerfrom the position where the tip of the point burnerfaces the openingto the standby position. At least in the second process and the fourth process, the flamehaving heating power weaker than the heating power of the flameof the point burnerapplied to the inner surface of the vialin the third process is ejected from the point burner
