Developer replenishing container

TL;DR: In this paper, a tare tape whose width is smaller than an opening is stuck to at least both end parts of the inside surface of a cover film, one end side is extended and turned back to the outside surface of the cover film 1, and a free end 2B of a turned-back tape part 2A is projected as a holding part to outside of the container end part of the opposite side to the turned back side.

Abstract: PURPOSE:To smoothly and surely form a developer supply use opening of prescribed width by sticking a tare tape whose width is narrower than an opening, to the inside of a film which has been stuck to the periphery of an opening of a developer replenishing container, turning it back and projecting one end to the outside of the container. CONSTITUTION:A film 1 is stuck 3 to an outward flange 12 surface of four peripheral edges of an opening part 11 of a developer replenishing container C. A tare tape 2 whose width W2 is smaller than width W1 of an opening is stuck 4 to at least both end parts of the inside surface of the film 1, one end side is extended and turned back to the outside surface of the cover film 1, and a free end 2B of a turned-back tape part 2A is projected as a holding part to the outside of the container end part of the opposite side to the turned- back side. At the time of replenishing a developer in the container C into a developing device body, the cover film 1 side of the container body 10 is turned downward and fitted and attached to a container installing part of the body 10, the holding part 2B of the tape 2 is held and drawn to the outside, the film 1 is ruptured by the width W2 of the tape 2 successively from the part 2A, and the film 1 is eliminated from the opening part 11.
