Abstract
A container and finger-depressible pump combination having improved non-leaking characteristics when the container holds a fluid (e.g., a volatile fluid such as nail polish remover) is described. The container which holds the fluid has a finger-depressible pump joined to its opened upper neck with the portion of the pump normally extending into the fluid in the container being encased in a closed but removable shroud which encases and isolates that portion of the pump and the adjacent portions of the pump from contact with the fluid. The shroud is a generally tubular structure being closed at its lower end and having circumferential flange means at its opposed open upper end which are adapted to be seated upon the upper land surface of the container neck underneath a portion of the cap holding the pump.
