Drums of thermoplastic synthetic material include a circumferentially extending carrying and transport ring arranged on the drum wall in the vicinity of the upper bottom, and at least one bunghole connection sleeve arranged in a trough-shaped indentation of the upper head of the drum in the area of the rim thereof. An integrally formed stiffening bead is arranged on the inner side of the carrying and transport ring of a drum of the above-described type in the vicinity of a bunghole connection sleeve. A stiffening hump is formed in the upper head of the drum between the stiffening bead of the carrying and transport ring and the bunghole connection sleeves.
