Trigger sprayer
A trigger sprayer for connection to a container or liquid product which is to be dispensed is disclosed. The trigger sprayer includes a trigger body with a first engagement member and a nozzle with a second engagement member. The first engagement member is constructed and arranged to receive the second engagement member. The second engagement member is moveable relative to the first engagement member between a first position and a second position. Movement of the second engagement member relative to the first engagement member between the first and second positions encounters a region of increased resistance.
1. A trigger sprayer selectively connectable to a fluid carrying container comprising:
a body including a flow passage for the fluid, the flow passage terminating at a proximal end of the body proximate to at least one post;
a nozzle connected to the proximal end and including a sleeve;
wherein the post and the sleeve are: (i) configured to engage one another along a common surface and (ii) cooperate to allow rotation of the nozzle relative to the body between a first position and a second position, with a region of increased resistance provided by a cross-sectional shape of the post relative to a cross-sectional shape of the sleeve; and
wherein, along the common surface, the cross sectional shape of the post consists of a circular outer surface with equally spaced flat portions conforming to a square overlaid therein and the cross-sectional shape of the sleeve consists of a circular inner surface with equally spaced flat portions conforming to a square overlaid therein formed therein.
2. The trigger sprayer of claim 1 wherein rotation of said flats of said post with one of said flats of said sleeve denotes one of said first and second positions.
3. The trigger sprayer of claim 1 wherein the sleeve is concentrically fitted around a distal end of the post.
4. The trigger sprayer of claim 1 wherein said first position is either an ON condition or an OFF condition for said trigger sprayer.
5. The trigger sprayer of claim 1 wherein a shroud is fitted over the body.
6. The trigger sprayer of claim 5 wherein the body includes at least one reinforcing member formed at a high stress point within the body.
7. The trigger sprayer of claim 1 wherein a shell-shaped shroud having at least one snap-fitting formed on an inner surface is coupled to at least one corresponding snap-fitting formed on an outer surface of the body.
8. The trigger sprayer of claim 7 wherein the inner surface includes a web of ribs.
9. The trigger sprayer of claim 8 wherein the shroud is formed from a semi-resilient material.
10. The trigger sprayer of claim 2 wherein each alignment of the post and the sleeve into the first position and the second position produces an audile click and/or tactile feedback.
