An actuating device for a dispensing pump of a dispenser is configured to be used on a container, in an upward position of the container. The actuating device includes a pouring cup and a connecting device. The pouring cup defines an inner chamber for receiving a metered amount of a product. The connecting device includes a hollow structure extending along a longitudinal axis between at least a first end and an opposite second end. The structure is connected and supports the pouring cup. The structure defines a channel extending along the axis between an input opening and an output opening. The output opening emerges into the inner chamber whereby the channel communicates with the inner chamber. The second end includes a connecting portion configured to be connected to a hollow stem of the dispensing pump whereby the channel communicates with a dispensing cavity defined by the stem.
