Child-resistant closure for containers, in particular for receiving pourable products

摘要

A child-resistant closure for containers for receiving pourable products comprises an inside part (1), which can be attached to the container, and an outside part (20) which is held rotatably by the inside part. Provided in each case in the inside part and the outside part is at least one through-opening (5, 26), which through-openings can be moved into and out of an aligned position by rotating the outside part relative to the inside part. Arranged on the inside part (1) is a coupling projection which is engaged with a complementary hole in the outside part when the rotary position of the outside part (20) is fixed relative to the inside part (1) and can be moved out of engagement with the hole by a force acting from the outside. Constructed in the bottom wall of the inside part (1) is a circumferentially extending, resilient wall region (8) which has a cross-sectional configuration providing a depression. The resilient wall region improves the spring characteristic or the restoring capacity of the inside part (1) when the actuating force is removed immediately after actuating the coupling projection. As a result, a permanent, sealing position is secured between the surfaces of the inside part (1) and of the outside part (20) which rest against one another. <IMAGE>
