arranged inside the container 16 the width of the sealing edges 3 may be optimized i e increased in relation to the width of conventional sealing edges in order to further improve the securing of the pouch inside the container furthermore the inner surface of the container 16 and or the outer surface of the pouch 1 may be provided with a friction enhancing surface such as a rugged surface when the actuator surface 15 of the nozzle member 9 is pressed on this will result in the entire nozzle member being pressed down whereby the lower end of the tube member 11 will be forced into the hole 7 of the mounting cup 5 and effect release of the valve body 6 a so that a flow of ophthalmic solution will take form in the tube member 11 because of the pressure acting on the pouch 4 within the can 16 in an alternative male type embodiment of the nozzle member not shown as is well known per se the vertical part of the tube member is formed by a separate part which is mounted in the hole 7 of the mounting cup 5 in this case the nozzle member 9 exhibits a larger diameter.
