Patent ID: 7237678

Claim:
A display box for housing and retaining cylindrical containers with a portion of their lateral surface visible through a window provided in the box, comprising four side walls having lower ends and, respectively, upper ends from which there project a bottom lid and respectively a top lid, and upper and lower elongate flaps in which creasing lines are provided along which said upper and lower elongate flaps are folded with at least one portion thereof being in contact with and being glued onto the inner surface of the side wall from which each respective upper and lower flap projects, at least one of the lower elongate flags forming for the container a support which is spaced from the bottom lid of the box, and wherein the upper elongate flaps are configured to form, for the top of the container, a pressing structure which is spaced from the top lid of the box, wherein each of the upper elongate flaps is configured to be folded and partly glued onto itself such as to lie substantially flat and coplanar with that side wall of the box from which it projects when said upper elongate flap is in its extended position with a portion thereof projecting from the upper end of the box but, by simply turning the upper elongate flap over towards the box interior, to undergo deformation and to automatically form a surface arranged to rest and press on the top of a container inserted into the box, causing a substantially semiarch-shaped edge of an aperture provided in a portion of said upper elongate flap to simultaneously project towards the interior of the box, such that a cylindrical upper lateral surface of a container inserted into the box is securely retained laterally by said substantially semiarch-shaped edges of the upper elongate flags and at the same time is pressed by said upper elongate flaps towards and against the support for a base of the container, wherein each of said upper elongate flaps is divided into eight separate consecutive flap portions separated from each other by parallel folding lines, in first two flap portions closest to that side wall of the box from which they project there being provided a large profiled hole extending on both sides of the folding line which separates said first two flap portions from each other, an elongate aperture being provided in fourth and fifth flap portions on one and on the other side of the folding line which separates them, said aperture being bounded by said substantially semiarch-shaped edge which is provided in said fifth flap portion.
