• This label 4 is positionable in a partially detachable and attachable manner on the outer wall of the packaging 1, in correspondence with a breaking primer formed on said packaging envelope. This breakthrough can affect a large number of shapes.
• This incipient fracture is to facilitate the tearing of the wall of the casing during the printing of the label and to control this tear during a first detachment of the label 4 in order to define an extraction opening 11 through which the products contained in the bag can be extracted.
• This rupture of the wall develops to a limit stop 7, 8 delimiting an edge of the opening 11 extraction.
• the label In this end-of-travel position, the label obviously remains attached to the torn envelope portion.
• the extraction opening 11 can then be closed by refixing the self-adhesive label 4 which has adhesive portions extending generally around the torn envelope portion adhered to the label.

• This adhesive piece which can be made in one piece or in several pieces, constitutes an interface between the outer wall of the package 1 and the label 3 in the affixed state of the label 3 on the packaging wall 1.
• the nature of the adhesive covering the dorsal of the label 3 can be chosen solely according to the nature of the interface 5 and no longer according to both the nature of the interface 5 and the wall of the conditioning. This results in a simplification of the design of the opening / closing device.
• This adhesive interface is in turn intended to adhere permanently to the packaging wall 1.
• the adhesive used may therefore be a relatively strong adhesive ensuring a secure hold of the opening and closing device on the wall 1 of packaging .
• This adhesive interface is provided with at least one breaker primer 6 such as a notch, a prefent, a thinning of material, produced as a function of the rupture primer of the wall of the packaging 1 so as to cooperate with this last and ensure perfect control of the rupture of the interface 5 and the packaging wall caused during a first detachment of the label 4.
• detachment of the label is meant the drawing of the label up to end stop in which it remains attached to the packaging.
• the detached part of the opening and closing device is constituted by the label 4, the portion of the adhesive interface 5 extending inside the breakout primer 6 when this substantially affects the shape of an open frame, as shown in FIG. 1, and the packaging wall portion also being within this frame.
• the cut strip thus formed, during the first detachment of the label 4, is stopped when an end stop 7, 8 end is reached by the tears. This limit stop defines an edge of the opening 11 of extraction.
• this end stop can affect a large number of shapes.
• the limit stop 7 is formed by a precut of the interface 5 extending in a direction transverse to the detaching direction of the label 4 (shown in dashed line). so as to form a barrier marking the end of the progression of the assembly formed of the label 4, the portion of the interface 5 and the packaging part 1 torn during the first detachment of the label 4.

• the adhesive tape constituting the limit stop 8 can, in another embodiment, not shown, be positioned between the interface 5 and the outer wall of the packaging 1.
• this adhesive zone consists of the face of the top of the limit stop 8 made in the form of a double-sided adhesive tape extending in the plane of the interface 5 or between the interface 5 and the label 4. Thanks to the presence of this adhesive part, the user can block the cover label by its front face by positioning it on the adhesive strip thus released.

• this strip may be coated with a silicone or glacial material on its back.
• this device is, before positioning on the casing wall 1, stored in the wound state on a peelable support strip. It can thus be applied in particular by licking on packaging passing beneath a laying head equipped with such a storage reel of the opening and closing device.
• the opening of such a packaging is extremely easy. It is sufficient at first to grasp the tab 10 gripping and pull on the entire device. It is then noted, during a draw on the device, the detachment of the label 4 parts of the interface 5 intended to remain in position on the packaging and a drive by the label 4 of the part of the interface and the portion of the bag to be torn. This drive is performed to a predetermined end position that marks the delimitation of one of the edges of the opening 11 extraction thus formed. In this end-of-travel position, the label can be held in the open position of the opening by tearing off the strip 9 and fixing the front of the label 4 on the adhesive strip thus discovered by tearing off the strip 9. once the bag emptying operations performed, the label is repositioned on the interface 5 to close the opening 11 extraction. The bag can thus be kept in the closed position until a new use of the bag.
