on the outside of the button 3 the two steps 45 47 are positioned in a side by side relationship see fig8 and 9 thereby preventing rotation of the button 3 more particularly upon tilting of the button 3 the lowermost edge portion 49 step of the button 47 pivots against the step of the sleeve 45 to prevent rotation of the button 3 when tilted a third embodiment of the retaining means comprises a protrusion 51 disposed on the inside of the sleeve 5 that cooperates with another protrusion 53 disposed on the outside of the button 3 see fig1 upon tilting the button 3 the protrusion of the button 53 resiliently overrides and is seated on top of the protrusion 51 of the sleeve thereby cocking or retaining the button 3 into a 34 on 34 position see fig1 to uncock the button 3 the button is simply pushed in the reverse direction which causes the protrusion 53 of the button to slip off of the protrusion 51 of the sleeve hence the button 3 returns to the vertical 34 off 34 position similarly a fourth embodiment of the retaining means comprises a protrusion 55 of the sleeve cooperating with a lowermost flanged edge 57 of the button 3 see fig1 the flanged edge 57 overrides the protrusion 55 of the sleeve and to seat on top of the protrusion 55 as the button 3 is tilted into the 34 on 34 position thereby dispensing the product and propellant see fig1.
