Embodiment Construction

[0033] As stated above, the present invention relates to a method of manufacture on an automatic assembly device for closing a closable bag comprising a closure assembly with a fixing plate for forming a device of the obviously destructible type.

[0034] The present invention can be applied to automatic bag-making machines with horizontal movement, and can also be applied to automatic bag-making machines with vertical movement.

[0035] In addition, the invention is also applicable to automatic bag-making machines where filling is performed during a step after manufacture and possibly at a location separate from that of manufacture, as well as to filling and closing at a single location and during successive steps on "form, fill and seal" (FFS) type production equipment in commonly used British terminology.

[0036] Therefore, the invention is preferably and advantageously applied to machines of the FFS type with vertical movement.

Abstract

The invention relates to a closure assembly (1) comprising complementary closure sections (2) and panels (6a, 6b) for fixing said closure assembly to the internal faces of a bag. The inventive assembly is characterised in that it comprises: sealing bands (11, 13) which are disposed on the external faces of the fixing panels (6a, 6b); a precut or line of weakness (10) which is made in one of the fixing panels (6a) and which divides said panel (6a) into a first external part (61a) and a second internal part (62a), the sealing band on the panel being limited to the external part of same; and a sealing band (12) which is disposed on the internal face of at least one of the panels, each internal sealing band being disposed on the internal part of the fixing panels.

Description

technical field [0001] The invention relates to the field of packaging bags. [0002] The invention relates in particular to a method for the manufacture of a bag comprising a closure assembly, in particular of a visibly tamperable type. Background technique [0003] A number of bags and devices for the manufacture of these bags have been proposed, in particular devices for fastening to bag closures including devices of the obviously breakable type. [0004] figure 1 An embodiment of a known closure assembly 1 is shown. It comprises a complementary profile 2 for opening and closing the opening 3 of the bag. The complementary section 2 is advantageously opened or closed by means of a mobile slider 4 . [0005] exist figure 1 Also seen in the device is the means for providing initial protection and opening indicator action, consisting of a strip 5 which, in the initial state, extends through the opening of the bag and which must be snapped off to gain access to the conten...
