Abstract
A removable and reclosable, substantially leak-free and fling-free cap member for sealably engaging the open top portion of a reusable shaker dispenser bottle or similar container is provided. Reduction or elimination of product fling from the strap closure upon opening of the pouring orifice is provided by placing the hinge of the strap to the top of the sidewall and by introducing controlled weakness of the plastic in the hinge area. Controlled rotational flexibility about a defined axis of symmetry and side placement of thumb flanges permits easy removal of the cap without compromising sealing effectiveness. An inverted teardrop pouring orifice provides a controlled-flow, universal recipe orifice for dispensing thin viscosity and thicker viscosity fluid products, with or without particulates.
