ABSTRACT:
A protective cap for a writing, drawing or applicator element comprises an outer casing portion and within same a closure cap portion which has a cover portion for sealingly covering over the applicator member of the implement. The cap portion is connected to the casing portion by means of ribs which define between them through openings through which the interior of the cap is in fluid communication with the exterior thereof. The through openings are of an overall cross-section of at least 5 mm.sup.2 in order at least to reduce the risk of asphyxiation if the cap is unintentionally swallowed. The ribs are disposed in the region of the cover portion of the cap portion and are extended in the axial direction of the cap over the cover portion, whereby the through openings are oriented in particular in a radial direction.
