retainment of its initial shape in a conventional manner known well to those skilled in the art the compressed air is forced through spout 80 into the pressurization device of the invention as shown in fig3 the spout is inserted into the upper end of the axial cylindrical opening 53 and the combination of spout and tube are pressed down into the closure apparatus located in the pouring spout neck of the container a stub handle 82 helps the operator guide the spout into the pressurization device assembly fig1 and 3 show the bladder 46 expanded to occupy gaseous area 16 thus keeping the non liquid area of the container in a pressurized condition the injection of air or gas can be accomplished by various types of power operated air pumps or by the simple addition of a compressed gas from a pressurized container the materials used for the cap and bladder are materials that are well known in the field of plastics and rubber like materials and should be made of materials resistant to the anticipated atmosphere when it is desired to re open the container for use the person conducting the procedure need only to depress the push ring 18 with a finger 84 into the direction of arrow 86 this procedure is shown in fig4 it should be noted that.
