Abstract
A closing flap or clip is adapted to cap the edge of a carton in a first position and to free the access to a part of the edge in a second position. The flap passes from the first position to the second position by pivoting around a geometric axis that is perpendicular to the carton edge. The flap is formed from two panels or webs that are configured to fit on each of both sides of the edge when in the first position. First ends of the panels are crossed by the geometric axis. The flap has a hinge linking the two webs and includes means for connecting second ends of the opposing webs to their respective first ends.
Claims12
Clip element for closing a package (20) provided with an edge (21), said clip being adapted to cover said edge in a first position and to give access to a part (V) of said edge in a second position, said clip being adapted to pass from said first to said second position by pivoting (F5) about a geometrical axis (Y-Y′) substantially perpendicular to said edge, said clip comprising two webs (11, 12;
- 211, 212) adapted to be disposed on either side of said edge in said first position and of which a first end (114, 124;
- 314, 324) is traversed by said geometrical axis, characterized in that it comprises a hinge (13;
- 213) joining said two webs and means (117, 127) for connection (F4, F′4) of said second ends (115, 125;
- 315, 325) of said two webs opposite their respective first ends (114, 124;
- 314, 324).
Clip element according to one of the preceding claims, characterized in that said second ends (115, 125;
- 315, 325) of said two webs (11, 12;
- 211, 212) present thicknesses (e′1, e′2) greater than those (e1, e2) of the principal parts (111, 121) or of the longitudinal edges (112, 122) of said webs.
Clip element according to one of the preceding claims, characterized in that one (11;
- 211) of said webs bears, at its first end, an extension (113;
- 313) extending in a direction (Y-Y′) substantially perpendicular to said web, and adapted to be inserted (F1) in a passage (24) of corresponding shape provided in said edge (21) in order to constitute a mechanical pin for articulation of said clip element (10;
- 210) on said edge.
Clip element according to one of the preceding claims, characterized in that it is made by molding flat, said connection means (117, 127;
- 317, 327) and, as the case may be, said extension (113;
- 313) being in one piece with said webs (11, 12;
- 211, 212) and with said hinge (13;
- 213).
Clip element according to one of the preceding claims, characterized in that said webs (211, 212) are provided with openings (3134, 3135;
- 318) for passage of slides for molding said connection means (317) and, as the case may be, said extension (313).
A package (20), particularly of the cardboard box type, provided with a multi-ply edge (21) adapted to be opened (V), characterized in that it is provided with a clip element (10;
- 210) according to one of the preceding claims.
Method for manufacturing a package (20) provided with an edge (21) adapted to be opened (V), and with a clip element (10) for closure, characterized in that it comprises the steps of:
- molding said clip (10;
- 210) flat, forming two webs (11, 12;
- 211, 212) and a hinge (13, 213) connecting said two webs;
- mounting said clip on said package by introducing (F1), in a passage (24) made in said edge (21), an extension (113;
- 313) extending from a first web (11;
- 211) in a direction (Y-Y′) substantially perpendicular thereto;
- folding (F2) said clip along (X-X′) said hinge, bringing a second web (12;
- 212) toward said edge, and
- connecting said two webs (11, 12;
- 211, 212) at their respective ends (115, 125;
- 315, 325) opposite their zones (114, 124;
- 314, 324) closest to said extension.
