<p>A safety-cap (100) having an inner sleeve (120) having a first threaded portion (121) that fits the threads (111) on a cap (110) and a second threaded portion (122) that fits the thread (211) around an opening of the interior of a container (200). An outer sleeve (130) is disposed concentrically, axially sliding and rotationally fixed around the inner sleeve (120). The cap (100) has a closed position in which the outer sleeve (130) is pressed axially between the lid (110) and a abutment surface (201 ) of the container ( 200 ) and retaining means (113, 135) adapted to retain the outer sleeve (130) temporarily fixed to the cap (110) while the safety cap (100) is rotated from the closed position to a position in which gas can escape from the container (200) between the outer the sleeve (130) and the support surface (201). A hosepipe can be fixed in a groove (125) of the inner sleeve, and inverted into the container when not in use. A container (200) using the safety-cap (100) and which can be stacked snugly during storage and transport are also described.</p> |
