ABSTRACT:
An opaque rear cover part for a one-time-use camera comprising a door cover portion and a remaining cover portion arranged to permit the door cover portion to be pivoted open relative to the remaining cover portion about a pivot axis, and a fracture line of weakness formed between the door cover portion and the remaining cover portion to create a break along the fracture line of weakness which permits the door cover portion to be separated from the remaining cover portion when the door cover portion is pivoted open, is characterized in that the fracture line of weakness is not coincident with the pivot axis in order to effect a shearing stress in addition to a bending stress at the fracture line of weakness, which causes the door cover portion to separate from the remaining cover portion when the door cover portion is pivoted open.
