The problem to be solved by the invention consists in the provision of a one-piece plastic enclosure, in particular made of PE-material, which can be placed on a filled container without satisfying particular tolerance requirements while simultaneously satisfying the additional, in part contradictory requirements, namely, to be manufactured in a few steps and to be apt for recycling after use, while ensuring reliably the guarantee function and the sealing function, for the closed container. The solution consists in a closure cap which has an extended guarantee band and an extended inner seal, i.e. a seal which projects about and along the edge of the container neck into the opening, which is characterized by a funnel- or bell-shaped prolongation at the free end of the guarantee band, a wedge- or funnel-shaped outer surface on the-extended inner seal, and an average standard solidity of the plastic material of the one-piece closure cap (in particular as to solidity of the PE-material) such, that the funnel-or bell-shaped guarantee prolongation sits on the supporting collar in a non-undergrippable manner and the funnel-shaped outer surface of the inner sealing rests elastically pressing on the container neck.

1. A one piece plastic closure cap (2, 3, 4, 5, 6, 7, 12, 18, 19, 5, 6, 16) for a container (1; 100) having a closure mechanism (2; 12) for disengageably fastening the closure cap on an opening of the container wherein the container has a bulge or projection on the container, a supporting collar to suspend the container during filling and a neck which has an edge_at the opening of the container comprising:a) a removable guarantee band (6) wherein the removable guarantee band has a funnel shaped or bell shaped prolongation at a free end and has a height in the direction of the central axis of the closure cap which extends beyond the bulge or projection to said supporting collar so that when fastened to the container the funnel shaped or bell shaped prolongation is capable of sitting on the supporting collar in a non under grippable manner and the removable guarantee band is pressed against the lower side of the bulge or projection, b) sealing lips having a inner seal which has a wedge or funnel shaped outer surface which is capable of resting on the inside surface of the container neck in a pressing manner; and c) a plastic material for the construction of the closure cap having the property of being sufficiently hard to function as a guarantee band and at the same time soft for the sealing lips to seal.
