A protective cap (1) or container with a resilient opening is disclosed. The container generally includes top and bottom parts (2,3) connected to each other via a film joint (17,18) in a unilaterallypivotal fashion, and latched to each other in the closed state, with the top part (2) being biased under the resilience of a repeatedly profiled resilient body (20,20',20'') in the opening direction in reference to the bottom part such that upon actuation of the latching device (12-15) the top part pivots open from the bottom part (3) under the force of resilience it is pivoted open and remains inthe open position, with here the repeatedly profiled resilient body (20,20',20'') being made from a soft-elastic elastomer plastic material and fastened unilaterally at flaps connected thereto with the same material, at the two facial sides of the top part and the bottom part (2,3).
