Abstract
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.

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.
