<p>PROBLEM TO BE SOLVED: To restrict the increase of the number of particulates at the time of preserving an injection liquid formulation filled in a plastic container and to reduce an insoluble foreign matter and the particulates by permitting the density of oxigen gas inside a head space part and/or a secondary wrapping material to be equal to below specified vol.%. SOLUTION: The density of oxigen gas with a gas composition inside the head space part and/or the secondary wrapping material is adjusted to be equal to below 10 vol in an injecting agent which is filled in a gas transmissive plastic container and wrapped by an oxigen gas non-transmissive and secondary wrapping material. It is favorable that it is adjusted to be equal to below 7 vol. The adjusting method is the one, for example, for sealing inert gas such as nitrogen gas, etc., which does not contain oxigen gas between the plastic container and the secondary wrapping material or for sealing a disoxidizer. Or, the method is the one for bubbling the injecting liquid by inert gas or for replacing the head space part with inert gas. Thus, the increase of the number of the particulates at the time of preservation is restricted.</p> |
