Trigger pump dispenser

An improved pump dispenser for discharging a fluid from a fluid reservoir, comprising:

• a pump body extending between a first and a second cylindrical end;
• a pump body orifice located in said first end of said pump body;
• a piston slidably mounted in said pump body;
• a base supporting said pump body relative to the fluid reservoir;
• a trigger extending a between a first portion and a second portion;
• a base pivot pivotably mounting said trigger relative to said base;
• and
• a first and a second cam defined in said first portion of said trigger;
• a generally U-shape linkage straddling opposed sides of said pump body for engaging with said piston;
• a first and a second cam follower located on a first and a second distal end of said generally U-shape linkage for coupling with said first and second cams defined in said first portion of said trigger enabling a pivoting movement of said second portion trigger to move linearly said piston to spray fluid from said pump body orifice.

An improved pump for discharging a fluid from a fluid reservoir, comprising:

• a pump body with a piston slidably mounted therein for discharging a fluid through a pump body orifice:
• a base interposed between said pump body to the fluid reservoir;
• a one-way valve communicating said pump body with said fluid reservoir for enabling fluid to flow from said fluid reservoir into said pump body;
• a vent communicating said pump body with said fluid reservoir;
• a trigger pivotably mounted relative to said base;
• a trigger extending a between a first portion and a second portion with a trigger pivot disposed therebetween;
• a base pivot engaging with said trigger pivot for pivoting said trigger;
• and
• a cam and a cam follower coupling said first portion of said trigger with said piston for enabling a depression of said second portion trigger to move said piston to spray fluid from said pump body orifice.

An improved actuator for a pump, the pump having a pump body with a piston slidably mounted therein for discharging a fluid through a pump body orifice from a fluid reservoir, the improved actuator comprising:

• a base having a fluid reservoir attachment for connecting to the fluid reservoir;
• a base connector for securing the pump body to said base;
• a one-way valve communicating the pump body with the fluid reservoir for enabling fluid from the fluid reservoir to enter the pump body;
• a vent communicating the pump body with the fluid reservoir;
• a trigger pivotably mounted relative to said base;
• a trigger extending a between a first portion and a second portion with a pivot point disposed therebetween;
• a pivot mounted relative to said base for engaging with said pivot point for pivoting said trigger;
• and
• a cam and a cam follower coupling said first portion of said trigger with the piston for enabling a depression of said second portion trigger to move the piston to spray fluid from the pump body orifice.
