View Patent ↗A trigger sprayer having a valve body configured to accept a discharge valve for a pre-compression configuration or a valve and plug combination for a non-pre-compression configuration where the discharge valve may include a frame and valve which may be bi-injected or assembled to provide a pre-compression valve for the trigger sprayer.
1. A trigger sprayer, comprising:
a valve body, comprising:
an inlet;
a discharge passageway;
a pump chamber;
a pump chamber inlet between the inlet and the pump chamber;
a pump chamber outlet between the pump chamber and the discharge passageway; and
a valve seat on an end of the pump chamber outlet;
an inlet valve positioned in the pump chamber, comprising an inlet valve member seated against the pump chamber inlet; and
a discharge valve attached to the valve body, comprising:
a valve, comprising:
a body;
at least one outer edge;
at least one valve lip; and
wherein the at least one valve lip is seated against the valve seat and the at least one outer edge is seated against the valve body;
a frame retaining the at least one outer edge of the valve in a seated position against the valve body; and
wherein the frame further comprises two opposing latches.
2. The trigger sprayer of claim 1 , wherein the body comprises a body having a thickness T v , wherein T v is between about 0.40 millimeters and about 0.90 millimeters.
3. The trigger sprayer of claim 1 , wherein the body comprises a body having a thickness T v of about 0.50 millimeters.
4. The trigger sprayer of claim 1 , wherein the body comprises a body having a thickness T v of about 0.80 millimeters.
5. The trigger sprayer of claim 1 , wherein the at least one valve lip comprises at least one valve lip having a sloped surface.
6. The trigger sprayer of claim 1 , wherein the at least one valve lip comprises a circular shaped valve lip having at least one sloped surface.
7. The trigger sprayer of claim 1 , wherein the at least one outer edge comprises two outer edges.
8. The trigger sprayer of claim 1 , wherein the frame further comprises a frame rim.
9. The trigger sprayer of claim 8 , wherein the frame rim is configured to prevent displacement of the body past the frame rim during actuation of the trigger sprayer.
10. The trigger sprayer of claim 8 , wherein the frame rim further comprises an opening through the frame rim.
11. The trigger sprayer of claim 10 , wherein the valve further comprises a valve stem extending from the body and through the opening in the frame rim.
