Abstract

A dome-shaped molded component or device for use with an operative element, e.g. a hollow-charge mine, is adapted to be connected at a continuous rim with the operative element. The device comprises a flexible body formed of an elastic material and at least one venting means for venting a cavity defined by the body when the device is placed in its functional or operative position. The device also has a rib arranged on the body for causing the body to deploy from a collapsed introverted inoperative initial position to an extended extroverted, operative position. The body part of the device is compressed under elastic deformation and is held in this position by a retaining unit for applying an external force to the device so that the device is collapsed within the operative element. Upon release of the externally effective force, the rib effects the deployment of the body into its functional or operative position.
