The present invention relates to an improved adapter for a disposal package. The inventive adapter includes a first through hole, extending and terminating in a cylindrical socket, a second through hole provided to receive an aeration tube and a third through hole which opens into a tube socket designed to receive a transparent tube. The transparent tube is designed to be curved around to face toward the bottom of the package to indicate liquid level therein. The adapter is further provided with a cutting means formed in the shape of a triangular pyramid body having edges which form walls terminating in a tip. The base of the cutting edges is spaced a predetermined distance from a face of the adapter to provide a space therebetween thicker than the thickness of the package top to allow package top materials to enter into the space and form a seal. Before the adapter is installed, the aeration tube thereof is in a position reciprocated outwardly from the adapter with respect to its installed position and is covered with a stocking, with the open end of the tube being covered by an air and liquid tight cap. |
