Abstract
An applicator device includes a top and a bottom layer of a flexible material tightly connected at their borders. An edge constitutes a grip zone to handle the applicator. Parallel weakening lines in each layer define an application section and closely surround a pad of a material capable to retain an agent or an elevation constituting a confinement structure for an agent. The superposition of weakening line and border of agent carrying material or the elevation constituting a part of the confinement structure avoids a contact of the flexible material with the surface to be treated as the carrying material layer or the confinement structure serve as a spacer. As a consequence, the applicator is suited to be used on highly sensitive surfaces like skin or mucosa.

Applicator device (1) for applying an agent (35) to a delicate surface (36) comprising a top (3) and a bottom layer (5) of a flexible material and having along an edge a grip zone (26) where the top and bottom layer are connected to each other to form the grip zone, wherein parallel weakening lines (14, 16) extend within the top and the bottom layer starting and ending at the grip zone and defining an applicator section surrounded by excess material of the top and bottom layer substantially connected with each other to constitute a sealing around the applicator section, so that the material of the top layer and the bottom layer surrounding the applicator section can be ripped off along the weakening lines, and wherein the border of the application section is further substantially coincident with or recessed with respect to a border of an agent bearing portion on at least one of top or bottom layer or both of top and bottom layer, the agent bearing portion comprising one of:
- a volume (9, 11) of a material carrying an agent, or
- a confinement structure (46) shaped as a linear elevation and designed to retain an agent within the application section, wherein if an agent bearing portion is arranged on both of top and bottom layer, the agent bearing portions are designed substantially mirror-shaped so that their borders coincide.
