An analytical model for coronal propagation and the release of solar cosmic rays (SCR) is formulated and compared with data correlating type II bursts with SCR enhancements in interplanetary space. Consideration is given to the various time scales of acceleration of the particles and electrons at flare sites. The bottle model is discussed, which regards the SCR and flare ejecta as being formed on initially closed magnetic field lines. The possibilities that either the onset of a Rayleigh-Taylor instability (RT) or reconnection of open and closed magnetic field lines open the bottle are examined. It is found that solar P events involve flare conditions which can feature an RT that has sufficient stability for opening to occur. Energetic electrons may be emitted by the same process that opens the bottle.
