1. A container (1) for a product, said container comprising
a discharge device (4) including means for discharging the product through a product dispensing opening (3), said discharge device (4) comprising a nozzle (12) and a spray conduit (10) connected to said nozzle (12), said spray conduit (10) having a continuous inner wall (15);
a valve plate (37) formed with an annular recess;
a valve comprising a valve stem (11);
means for suppressing noise produced by a product discharge when dispensing the product by means of the discharge device;
and
a cap (7) engaged on a remaining part of said container (1);
in which said discharge device (4) comprises a button (6) provided in said cap (7) so that, when said button (6) is actuated, said spray conduit (10) acts mechanically with said wall (15) on said valve stem (11) to actuate said valve;
in which said means for suppressing said noise produced by said product discharge comprises a valve plate insulation (38) applied to and extending on said valve plate (37); and
in which said valve plate insulation (38) comprises a layer of polyurethane foam applied to said valve plate so that said layer of said polyurethane foam fills said
annular recess and extends above and over said valve plate from a bottom of said valve plate so as to form a plane surface,
said plane surface extends above and over said valve plate, and said polyurethane foam is provided with a plurality of pores
and an open-pored structure with a porosity of up to 95% such that said noise produced by said product discharge is minimized.
