A closure for a plastic canister in the 20-30 liter range has a collar coaxial with a pouring spout on the canister, with side abutments with lower surfaces arranged to cooperate with the claws of the closure. A cap is arranged to swing between an open condition and a closed condition relative to the collar. The claw is approximately U-shaped, with a transverse gripping web and two longitudinal webs ending in a fork having an upper and a lower prong. The upper prongs are arranged to form a swivel hinge with journals on the cap. The lower prongs have inner surfaces arranged to cooperate with lower surfaces of the abutments such that when the gripping web is pressed downward a sealing ring in the cap is pressed onto the end face of the pouring nozzle. The collar is arranged to fit against the cap with minimal spacings and the claw is arranged to fit against the collar and the cap with minimal spacings, when the cap is in the closed condition. The spacings permit relative movement of the claw and the cap during opening and closing of the cap, and are smaller than deformations occurring as a result of impact loads on the closure.

A closure for a plastic canister in the 20-30 liter range, said canister having integral therewith a plastic pouring spout with an end face, said closure comprising a collar coaxial with said pouring spout, having a rearward periphery and sides having two abutments, said abutments having lower surfaces arranged to cooperate with claws of a claw-type closure, a cap with a sealing ring therein and lateral and rearward edge regions, said cap being arranged to swing between an open condition and a closed condition relative to said collar, a first hinge half projecting from said rearward periphery of said collar, a second hinge half on said rearward edge region of said cap that cooperates with said first hinge half, said first and second hinge halves being shaped to prevent said cap from swinging to said closed condition when said cap is in said open condition, two journals arranged on said lateral edge regions of said cap, and a claw that is approximately U-shaped, seen in plan view, with a transverse gripping web with end regions, and two longitudinal webs emanating from said end regions, each of said longitudinal webs ending at a free end in a fork having an upper and a lower prong as seen in said closed condition of said cap, each of said upper prongs being arranged to form a swivel hinge with said journals, each of said lower prongs having an inner surface arranged to cooperate with said lower surfaces of said abutments such that when said gripping web is pressed downward said sealing ring in said cap is pressed onto said end face of said pouring nozzle, said collar being arranged to fit against said cap with minimal spacings and said claw being arranged to fit against said collar and said cap with minimal spacings, when said cap is in said closed condition, said spacings permitting relative movement of said claw and said cap during opening and closing of said cap, said spacings being smaller than deformations occuring as a result of impact loads on said closure, said claw being composed of plastic.
