The receptacle has a space in which a pair of sliding pieces are disposed for an engagement with a projection of the cover. The sliding pieces are connected together in such manner that the inner ends approach each other to hold the projection therebetween when the outer ends are located away from each other and projected beyond the side walls of the receptacle by an elastic means. A means is provided for maintaining the cover in the closed position and upon rearward movement of the main container with respect to the tray, for releasing the closed position of the cover.
