the lower or bottom surface 42 can be provided with a taper or chamfer 45 for concentrating pressure on the central portion of the diaphragm 39 above the valve neck 35 this taper or chamfer depending on its size can provide a liquid path around the base of the nib or can cover the slot openings 14 for direct access of fluid to the nib base the design depends on the type fluid being used and the type nib being used as well as the force necessary to press the diaphragm central area inwardly during non use the fluid within the fluid container 6 is sealed therein by the sealing lips 36 of the resilient closure cap 3 pressing against the tapered valve seat 28 as shown in fig3 the fluid within the container can be dispensed to the implement 4 by holding the container 6 in the inverted position and pressing the implement 4 against a surface or object as shown in fig4 upward and inward pressure on the inverted implement 4 is transferred to the diaphragm area 39 where it acts against the now downward force created by the dome area 32 of the resilient cap 3 overcoming the diaphragm resistance results in an inward movement of the valve neck 35.
