Abstract

An application device (1) for applying a viscous material onto a substrate and a method for producing the application device (1). The application device (1) includes a ventilation device having an insert (19), which is connected air-tightly to an inner container (3) in the region of a discharge opening (18). An annular gap is formed between the insert (19) and a neck region (6) of the outer casing (2), through which annular gap air can flow from outside into an intermediate space between the outer casing (2) and the inner container (3) and vice versa. The connection between an applicator (4) and the outer casing (2) is also permeable to air and the applicator (4) includes a sealing means (25) that seals off the inner volume of the inner container (3) in an air-tight and leak-proof manner from the intermediate space.
