A wide-necked extrusion blow-molded plastic container for bulk material as disclosed for a closure cap configured for mounting on a container neck of the wide-necked plastic container opening. A casing of the closure cap configured for connecting to an outside wall of a body of the wide-necked plastic container. A number of locking projections distributed over a periphery of the container neck which project from an outside wall of the container neck, and which are arranged on an outside wall of the container neck, the closure cap being equipped on an inside wall of its casing with corresponding locking recesses, which during mounting of the closure cap on the container neck engage with the locking projections to lock with one another in a non-detachable manner, the interacting locking projections and locking recesses being inaccessible in the mounted closure cap.

1. A wide-necked extrusion blow-molded plastic container for bulk material, comprising: a closure cap configured for mounting on a container neck of a wide-necked plastic container opening;a casing of the closure cap adjoining an outside wall of a body of the wide-necked plastic container; anda number of locking projections distributed over a periphery of the container neck which project from an outside wall of the container neck, and which are arranged on the outside wall of the container neck, the closure cap being equipped with corresponding locking recesses, which during mounting of the closure cap on the container neck will engage with the locking projections to lock with one another in a non-detachable manner, the interacting locking projections and locking recesses being inaccessible in the mounted closure cap, the closure cap being configured to be removable after mounting only by destroying one or more of the locking recesses and/or locking projections;wherein the locking projections are each configured as locking strips that extend in a peripheral direction and that interact with respective locking recesses, the locking recesses each being provided in a skirt that projects from an inside wall of the casing of the closure cap as a substantially L-shaped projection. 2. The wide-necked plastic container with a closure cap according to claim 1, comprising: on the outside wall of the container neck, at least a first centering element; anda second centering element, that corresponds to the at least one first centering element, on the casing of the closure cap, whereby in a mounting of the closure cap on the container neck, the at least one first centering element and the second centering element are configured to engage with one another in such a way that after the mounting, the closure cap and the container neck are centered relative to one another. 3. The wide-necked plastic container with a closure cap according to claim 2, comprising: a number of first centering elements, and an equivalent number of corresponding second centering elements. 4. The wide-necked plastic container with a closure cap according to claim 3, wherein the locking projections and the first centering elements are arranged alternately at least in certain areas along the periphery of the container neck, and the locking recesses and the second centering elements are provided alternately at least in certain areas on the casing of the closure cap. 5. The wide-necked plastic container according to claim 4, wherein each first centering element is configured as a centering projection that projects from the outside wall of the container neck, and wherein each second centering element is configured as a centering recess. 6. The wide-necked plastic container with a closure cap according to claim 5, wherein each centering projection has a radial protrusion (h) relative to the outside wall of the container neck, which is 0.5 mm to 5 mm. 7. The wide-necked plastic container with a closure cap according to claim 5, wherein each centering projection is configured as a pin with an essentially cylindrical outside contour. 8. The wide-necked plastic container with a closure cap according to claim 5, wherein each centering projection has a triangular outside contour, whereby a tip of the triangle is oriented in a direction of the container opening. 9. The wide-necked plastic container with a closure cap according to claim 5, wherein each centering projection has an equilateral triangle shaped outside contour, whereby a tip of the triangle is oriented in a direction of the container opening. 10. The wide-necked plastic container with a closure cap according to claim 1, wherein the locking strips in an axial section have an essentially triangular shape and comprise: an essentially radial locking surface and a sloped surface, which sloped surface extends from a maximum radial protrusion of the locking strip opposite the outside wall of the container neck obliquely in a direction of the container opening. 11. The wide-necked plastic container with a closure cap according to claim 10, wherein the radial locking surface relative to the oblique sloped surface enclose an angle (α), which is 25° to 75°. 12. The wide-necked plastic container with a closure cap according to claim 1, wherein the locking strips have a maximum radial protrusion (r), which is 0.5 mm to 5 mm. 13. The wide-necked plastic container with a closure cap according to claim 1, wherein the skirt that projects from the inside wall of the casing of the closure cap is divided by axially extending indentations into strap-like segments, whereby each segment has a locking recess. 14. The wide-necked plastic container with a closure cap according to claim 13, wherein the axially extending indentations are arranged and configured such that in mounting of the closure cap on the container neck, any segment, independently of its adjacent segments is movable elastically reversibly from a first position into a second position, whereby in the first position, the closure cap is prepared for mounting on the container neck, and in the second position, the segment is maximally radially deflected during the mounting of the closure cap on the container neck by a locking element. 15. The wide-necked plastic container with a closure cap according to claim 13, wherein the axially extending indentations at least in part form centering recesses. 16. The wide-necked plastic container with a closure cap according to claim 15, wherein each centering recess has an essentially equilateral triangular contour, whereby two legs of a same length form a tip of a triangle, which is oriented to the container neck opposite a mounting direction of the closure cap. 17. The wide-necked plastic container with a closure cap according to claim 1, wherein each locking recess has a chamfered lower boundary arm, which has an outside surface that extends from the locking recess obliquely in a direction of the casing of the closure cap. 18. The wide-necked plastic container with a closure cap according to claim 17, wherein the chamfered lower boundary arm has an extension that when measured in an axial direction is 1 mm to 10 mm. 19. The wide-necked plastic container with a closure cap according to claim 1, wherein the skirt has a wall thickness (w) that is 0.3 mm to 2.5 mm. 20. A wide-necked extrusion blow-molded plastic container for bulk material, comprising: a closure cap configured for mounting on a container neck of a wide-necked plastic container opening;a casing of the closure cap adjoining an outside wall of a body of the wide-necked plastic container; anda number of locking projections distributed over a periphery of the container neck which project from an outside wall of the container neck, and which are arranged on the outside wall of the container neck, the closure cap being equipped with corresponding locking recesses, which during mounting of the closure cap on the container neck will engage with the locking projections to lock with one another in a non-detachable manner, the interacting locking projections and locking recesses being inaccessible in the mounted closure cap, the closure cap being configured to be removable after mounting only by destroying one or more of the locking recesses and/or locking projections;wherein the locking projections are each configured as locking strips that extend in a peripheral direction and that interact with respective locking recesses, the locking recesses each being provided in a skirt that projects inward from an inside wall of the casing of the closure cap.
