Abstract: A device (1) comprises a reservoir (2), preferably having a transparent wall (8), for holding a flowable product (3) and a dispensing head (4) for discharging the product (3). The dispensing head (4) is joined to the reservoir (2) via a coupling (5), especially a threaded coupling. Provided on dispensing head (4) is an actuator device (6) for opening and closing the dispensing head (4) as desired in order to dispense product accordingly from a discharge opening (18). In order to prevent erroneous refilling with product when an empty reservoir (2) is replaced with a full reservoir (2), especially when there is a set of reservoirs (2) having different products (3) for coloring hair, it is proposed that the product (3) be a powdered or granulate hair dye and that the surface of the dispensing head (4) or the actuator device (6) have an information surface (7) that is to be assigned to the product (3). The powder or granulate form thus serves to ensure recognition of the color of the product (3).

Abstract: In order to enable removal of any quantity of product with a container (1) with a device (2) to discharge product, particularly trickling or free-flowing product, with a reservoir (3) to hold the product, a product discharge opening (4), and a connection (5) between the reservoir (3) and the device (2), it is suggested that the container (1) have a channel (6), made of flexible material, which is provided for routing the product from the reservoir (3) up to the product discharge opening (4), that the device (2) have a clamping element (7) for optional clamping and releasing of the channel (6), that the clamping element (7) be spring-loaded in the direction of the channel (6) using a spring (8), and that an actuator device (9) be connected to the clamping element (7) via actuation mechanics (10), to enable optional clamping of the channel (6) via manual actuation of the actuator device (9).
