Abstract

550,240. Containers for kinematograph film. HUDSON; G. June 27, 1941, No. 8129. [Class 18] A kinematograph film is wound on a spool 13 with a hollow hub 14 with which a protuberance 17 on a canister body 15 and/or lid 16 engages lightly. The centralizing action of the protuberance or protuberances is not impeded by the wrapping paper 19 of the film. Frustro-conical protuberances may be used. Hub 14 may be omitted. The protuberances 17 may be formed by spinning, swaging or pressing.
