Abstract

A rigid hinged-lid packet for elongated items, particularly cigarettes; the packet being formed by folding a flat blank defined by a number of panels aligned with one another and each presenting two lateral wings; a first and second panel defining the front wall of a collar and the front wall of the container of the packet, and being connected to each other by an appendix foldable inside the second panel; a third and fourth panel defining the rear wall of the container and the rear wall of the lid of the container; each wing of the third panel and the corresponding wing of the fourth panel defining a recess engaged by the corresponding wing of the first panel; and each recess being so shaped and sized as to permit the passage of the corresponding wing of the first panel.

Claims

1. A rigid hinged-lid packet for elongated items, the packet comprising a cup-shaped container open at one end;

a cup-shaped lid hinged to the rear edge of and for closing said open end; and

a collar inserted inside the container and projecting outwards of the container through said open end;

the packet being formed by folding a flat blank comprising a number of panels presenting respective pairs of longitudinal edges, and a longitudinal wing located outwards of each longitudinal edge of each panel;

a first and second of said panels, presenting respective pairs of respective first and second said wings, defining the front wall of the collar and the front wall of the container;

a longitudinal appendix connecting the first and second panels, and being folded inside the second panel so that the first panel partly contacts the inner surface of the second panel; and

a third and fourth of said panels, presenting respective pairs of respective third and fourth said wings, respectively defining the rear wall of the container and the rear wall of the lid, said respective pairs of respective third and fourth said wings being connected to each other by a hinge connecting said lid to said container;

the packet being characterized in that each third wing and the corresponding fourth wing define a recess engaged by the corresponding first wing;

each said recess being so shaped and sized as to permit the passage of the corresponding first wing.

2. A packet as claimed in claim 1, characterized in that each said recess and each said first wing are substantially in the form of a right angle trapezium.

3. A packet as claimed in claim 2, characterized in that each first wing presents a first and second edge extending respectively parallel to and perpendicularly to the relative said longitudinal edge;

and a third oblique edge;

the relative second wing presenting an oblique end edge (42) facing the corresponding third edge.

4. A packet as claimed in claim 3, characterized in that each said third edge and the relative said end edge of said blank diverge from the respective said longitudinal edge to define a recess, the minimum width of which, measured along said longitudinal edge, is less than twice the width of said appendix measured in the same direction, and the maximum width of which, measured in the same direction, is at least equal to said width of said appendix.

5. A packet as claimed in claim 4, characterized in that each said recess of said blank is substantially in the form of a right angle trapezium, wherein the longer side coincides with the outer edge of the relative said third and fourth wings and is parallel to the relative said longitudinal edge;

the shorter side is located adjacent to said longitudinal edge;

a first side, perpendicular to said outer edge, is located on the relative said fourth wing; and

a second side is oblique, parallel to said third edge of the relative first wing, and located on the relative third wing.

6. A packet as claimed in claim 5, characterized in that, in addition to the relative said recess, each said fourth wing is also detached from the relative third wing by a cut parallel to the relative said end edge and located between the relative end of said hinge and an intermediate point along the shorter side of the relative recess.

7. A packet as claimed in claim 1, characterized in that the length of each first wing, measured crosswise to the relative said longitudinal edge, is less than the width of the corresponding other wings measured in the same direction.

8. A packet as claimed in claim 1, characterized in that, at said first panel end, said blank is defined by a straight end edge extending also along said first wings.

9. A packet as claimed in claim 8, characterized in that a fifth of said panels defines the front wall of said lid;

said straight end edge projecting outwards of said second panel by a distance less than the height of said fifth panel.

10. A packet as claimed in claim 9, characterized in that said collar presents two longitudinal appendixes, each extending from said end edge and across a relative said longitudinal edge, and each defined by a free edge parallel to said end edge;

said free edge projecting outwards of said second panel by a distance substantially equal to the height of said fifth panel.

11. A packet as claimed in claim 10, characterized in that each said longitudinal appendix imparts to the respective said first wing a substantially L shape;

the corresponding said recess presenting a lateral recess formed by removing an end portion of the relative said fourth wing.
