Disclosed herein are compositions for the delayed delivery of peptide active agents, including compositions comprising; i) a salt of a peptide active agent comprising at least one positively charged peptide ion and at least one negatively charged counter-ion selected from a halide ion, a chloride and a bromide ion; and ii) a sustained-release delivery vehicle. The deterioration information generating circuit generates the deterioration information on the basis of a time, a luminance, a current value or a voltgage value, etc. The groups are sorted from most occurring entity to least occurring entity. The pressure relief plate positioned so that it covers the opening in the side of the flue pipe when the pressure relief plate is in the closed state.
