Abstract: A packaging comprising, a container made of plastic and comprising lateral walls, an upper opening and a bottom and, on the other hand, a lid that is made of plastic, is detachable and is configured to cover the upper opening of the container, and in which the container is provided at its upper opening with a first engagement portion bearing an outwardly directed ridge running around the periphery, said lid being provided on its peripheral part with a second engagement portion that extends folded downward and provided with an inwardly directed ridge which is able to latch underneath the outwardly directed ridge of the container, and in which the second engagement portion of the lid has a skirt with a skirt section that can be folded back and that bears a lug which is able to latch onto a second outwardly directed ridge of the container.

Abstract: When practicing the present invention, the manufacturer as an initial step, and starting from a given bucket 10, selects the thickness w30 of a second type lid 30 circumferential region 31 to be less than the thickness w20 of a first type lid 20 circumferential region 21 whereby the circumferential flange 38 of the second type lid 30 after application on the bucket 10 is more readily manually disengaged from said locking rib 16 by an outward flexural movement of the outermost wall 37. Hence, the second type lid 30 may conveniently be formed as a “flex-off”-type lid fitting the same bucket 10 as the first type lid 20. Making lids of the second type may be by using the same injection mold as used for the first type lid 20, modified by an inlay providing for the reduced wall thickness w30 and possibly for any minor differences in the design of the peripheral flanges 28, 38, such as the angle ? that the upper face A of the flange 28, 38 makes with the vertical, and the dimension ?, i.e.
