Abstract

A stopper for being sealed between two sheets of a reservoir, including a body defining a front face, rear face, internal edge, and external edge. The body forms a dispenser orifice that passes through from the rear face to the front face, the front and rear faces defining front and rear heat-sealing zones for the sheets. The front face defines a fluid collection zone at the orifice and the rear face defines a fluid delivery channel that extends from the dispenser orifice to the internal edge of the body. A closure lid is provided, the lid connected to the base body via a hinge. The body defines tapering side edges where the front and rear heat-sealing zones are contiguous, and the front and rear faces are convex, to define a maximum thickness where the dispenser orifice, the delivery channel, and a fraction of the collection zone are formed.
