A dosing device with a monolithic, resilient roll meters liquid detergent, softener, concentrates, cleaning agents, and other medium-viscosity liquids. The rolling application element is used for applying detergent to very dirty fabric areas. The monolithic roll () encompassing a shaft () and an outer jacket () with plastic recesses is inserted into a mount () of a dosing receptacle (). Radially extending spring lamellae are molded between the shaft () and the outer jacket ().

The invention relates to a dispenser pump (), for the non-dropping, dosed dispensing of liquid to pasty products from containers, for example, from bottles, canisters, or tubes, comprising a pump lower section () with a suction opening () and a pump upper section () with a moving lid (), for sucking up the product through the suction opening () of the pump lower section () into a suction chamber () and to dispense the product from said suction chamber (), through a dispensing channel () with an application opening (). According to the invention, a constructive simplification may be achieved, whereby the lower end of the suction chamber (), arranged beneath the lid (), is embodied by a floating elastic disc valve () which, on alternate axial displacement of the lid (), opens and closes the lower opening () of the dispensing channel section ('), due to arching of the mid-section thereof and conversely, by deformation of the outer boundary region () thereof, opens and closes the suction opening () of the pump lower section ().

An ink writing implement has a front part with a writing tip that comes into contact with the writing substrate, and a writing fluid cartridge whose interior chamber containing the writing fluid is tightly sealed before being put into use, and which is connected to the front part during use. There is also provided an equalization system disposed inside a housing and connected by one end to the interior chamber of the writing fluid cartridge and by the other end with the outside air. The writing fluid cartridge and front part are rigidly attached to one another. The front part can be inserted into the equalization system through a back opening and moved into a position in which it protrudes beyond the front opening in the housing.
