Roller shutter storage container

A roller shutter storage container comprising:

• a container body having an opening;
• a roller shutter accommodating portion arranged along a first direction so as to be adjacent to the container body;
• a pair of guide grooves formed in the opening of the container body and the roller shutter accommodating portion at both sides in the widthwise direction, which is a second direction perpendicular to the first direction, each of the guide grooves forming a straight shape in the opening, at least a portion of each guide groove being curved in the roller shutter accommodating portion, the guide grooves extending along the first direction;
• and
• a roller shutter guided by the two guide grooves, wherein
• the roller shutter includes a plurality of slats arranged along the first direction and connected together in a bendable manner, each of the slats having two ends in the second direction and shafts at the ends,
• as the shafts of each of the slats slide in the corresponding guide grooves, the roller shutter slides between an open position, at which the roller shutter is accommodated in the roller shutter accommodating portion to open the opening, and a close position, at which the roller shutter extends out from the roller shutter accommodating portion to close the opening,
• each of the guide grooves has a vertical wall surface extending in a direction substantially perpendicular to the second direction, and
• each one of the shafts is spaced from the corresponding one of the vertical wall surfaces, the shafts of at least some of the slats having projections formed of soft material and projecting outward along the second direction, each of the projections being held in contact with the corresponding vertical wall surface in an elastically deformed state,
• wherein the length of each projection is set to a value that is 1.5 times as great as the interval between each shaft and the vertical wall surface of the corresponding guide groove or greater.

• each guide groove has a pair of opposing lateral wall surfaces each extending substantially perpendicular to the associated vertical wall surface,
• each adjacent pair of the slats are connected together through a hinge,
• the hinges are located between the shafts of the slats and the ornamental surface,
• a rib formed of soft material is arranged between each one of the slats and at least one of the two adjacent slats, the rib restricting movement of the shafts of the corresponding slats,
• the rib extends in the thickness direction of the roller shutter at least at a position between the axes of the corresponding shafts and the hinge, and
• the rib extends to a position farther from the hinge than the axes of the shafts with respect to the thickness direction of the roller shutter.
