Abstract

Package including a receptacle (2) extending along a central axis (Z) up to a top face (23) having an opening (24), a closure system (3) including a cover (31) mounted so as to be articulated thereat between an open position and a closed position, and a locking device (4) including a locking lug (41) that is elastically deformable towards the central axis (Z) fastened to the cover (31) and furnished with a snout (43), and a gripping edge (42) secured to the receptacle (2) with which the snout (43) engages in the closed position. The cover (31) has a recess (47) in which the locking lug (41) is arranged. The locking lug has an actuation zone (41c) that can be accessed via the mouth (47a) of the recess, and a tamper-proof cap (51) is immobilized relative to the cover (31) by at least one breakable connection (52) and is arranged facing the actuation zone (41c).

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is a national stage application of International Application No. PCT / FR2008 / 050813, filed on May 7, 2008, which claims the benefit of French Patent Application No. 07 03395 filed on May 11, 2007, the entire contents of both applications being incorporated herein by reference.BACKGROUND OF THE INVENTION

[0002] The present invention relates to a reclosable package, designed in particular for a food product, which has a device for locking the closure system. More particularly, the invention relates to a package comprising:

[0003] a container extending along a central axis from a base as far as an upper face having an opening surrounded by a perimeter extending basically in a horizontal plane;

[0004] a closure system comprising a lid mounted on the container in hinged fashion between an open position and a closed position, in which latter it covers the opening; and

[0005] a device for locking the lid in the closed position and compri...

Embodiment Construction

[0027]In the various figures, identical reference numerals designate identical or similar elements.

[0028]FIG. 1 shows a package 1 comprising a container 2, a closure system 3, a locking device 4 and a tamperproof device 5.

[0029]The container 2 has a bottom 21, or base, from which an annular side wall 22 extends along a vertical central axis Z as far as an upper face 23. The upper face has a wide opening 24 surrounded by a perimeter 25. The perimeter 25 extends essentially in a horizontal plane coincident with the plane of the opening 24 and is formed by a collar extending radially toward the central axis Z. However, it is perfectly conceivable for this perimeter to be produced simply by the thickness of the material forming the side wall 22.

[0030]The container 2 has a basically rectangular cross section perpendicular to the central axis Z, with rounded corners. This cross section varies somewhat along the central axis Z in order to form a waist for gripping, but these variations rem...
