Abstract

A hinge-lid package has a box body ( 8 ) and a lid ( 6 ) which are formed from a blank. The box body ( 8 ) and the lid ( 6 ) have rounded edges ( 16 and 18 ) as longitudinal edges thereof. The rounded edge ( 16 and 18 ) has an arc-like shape created by a groove pattern formed only in the inner surface of the rounded edge. The groove pattern makes the corresponding lattice design (F) appear in the outer surface of the rounded edge ( 16 and 18 ).

First claim

The invention claimed is:

1. A package of rod-shaped smoking articles comprising:
a box body formed of paper material, the box body having an open end, said box body including a rounded edge forming at least one longitudinal edge extending along a longitudinal direction of said box body, the rounded edge having an arc-like shape as viewed in cross-section of said box body and a smooth outer surface;
a lid connected to the open end of said box body through a hinge, for opening and closing the open end; and
a plurality of cuts provided only on an inner surface of the rounded edge to keep an outer surface of the rounded edge smooth, the plurality of cuts creating a design appearing only on the smooth outer surface of the rounded edge, the design being caused by a groove pattern formed by the plurality of cuts; and
a reinforcing patch disposed on the groove pattern on the inner surface;
wherein the reinforcing patches are formed by glue applied to the inner surfaces and stretching across the groove patterns in the vicinity of the open end.

2. The package of rod-shaped smoking articles according to claim 1 , wherein the rounded edge is formed in each of four longitudinal edges of said box body.

3. A blank, comprising:
a main section extending in one direction, for forming a box body, and a subsection connected to one end of said main section through a hinge to form a lid; said main section formed of paper material and including:
a rear panel, a bottom panel, and a front panel aligned in the one direction, for forming a rear wall, a bottom wall, and a front wall, respectively, of said box body, the rear, bottom and
front panels, among which each two adjacent panels being connected to each other through a horizontal fold line; and
inner and outer side flaps connected to both sides of the rear panel and of the front panel through longitudinal fold lines, for forming inner and outer parts of side walls of said box body, wherein at least one longitudinal fold line is formed by a plurality of cuts on an inner surface for forming a rounded edge of said box body, the rounded edge having an arc-like shape as viewed in cross-section of said box body and a smooth outer surface; and
the plurality of cuts creating a design appearing only on the smooth outer surface of the rounded edge, the design being caused by a groove pattern formed by the plurality of cuts;
a reinforcing patch disposed on the groove pattern on the inner surface; and
wherein the reinforcing patches are formed by glue applied to the inner surfaces and stretching across the groove patterns in the vicinity of the open end.

4. The package of claim 1 , wherein the groove pattern is formed by a plurality of cuts, the cuts reducing a thickness of the rounded edge while keeping the outer surface smooth so as to provide the arc-like shape and the design on the rounded edge.

5. The package of claim 4 , wherein the reduced thickness of the rounded edge is less than 50 percent of the thickness between an inner surface and an outer surface of the rounded edge.

6. The package of claim 4 , wherein the cuts includes a first plurality of cuts and a second plurality of cuts at an angle to the first plurality of cuts to form the design into a plurality of columns and rows of diamond shapes.

7. The package of claim 6 , wherein a width of each diamond shape is less than the width of the rounded edge.

8. The package of claim 6 , the first plurality of cuts and the second plurality of cuts extend an entire length of the at least one of the longitudinal fold lines.

9. The package of claim 6 , wherein each of the first plurality of cuts extends across at least two of the second plurality of cuts.

10. The blank of claim 3 , wherein the groove pattern is formed by a plurality of cuts, the cuts reducing a thickness of the at least of one of the longitudinal fold lines while keeping the outer surface of the at least one of the longitudinal lines smooth so as to provide the arc-like shape and the design of the rounded edge.

11. The blank of claim 10 , wherein the reduced thickness of the at least one of the longitudinal fold lines is less than 50 percent of the thickness between inner and outer surface of the at least one of the longitudinal fold lines.

12. The blank of claim 10 , wherein the cuts includes a first plurality of cuts and a second plurality of cuts at angle to the first plurality of cuts to form the design into a plurality of columns and rows of diamond shapes.

13. The blank of claim 12 , wherein each of the first plurality of cuts extends across at least two of the second plurality of cuts.

14. The blank of claim 10 , wherein the cuts include a plurality of parallel cuts at angle to the one direction, the parallel cuts not being connected to one another to form the design into a slash design, and
wherein the plurality of the parallel cuts extend an entire length of the at least one of the longitudinal fold lines.

15. The blank of claim 11 , wherein the first plurality of cuts and the second plurality of cuts extend an entire length of the at least one of the longitudinal fold lines.

16. The blank of claim 11 , wherein a width of each diamond shape is less than the width of the at least one of the longitudinal fold lines.
