<p>#CMT# #/CMT# The device has two complementary closing sections (200, 300), and a slider (100) comprising a central wall (140), where the slider modifies a connection state of the sections to separate or engage the sections. The slider has two flanges (120, 130) and flexible lips (145, 146), which are placed on the top of the wall opposite to tapers (216, 316) provided on the sections based on a configuration such that an attempt of retraction of the slider forms self-blocking buttressing of the lip. #CMT#USE : #/CMT# Used for closing a sachet (claimed). #CMT#ADVANTAGE : #/CMT# The flexible lips are placed on the top of the wall opposite to the taper based on the configuration such that the attempt of retraction of the slider forms self-blocking buttressing of the lip, thus reinforcing the blocking of the lip against the taper, while limiting the stress of the flanges. The device permits several openings and closings of the sachet successively based on the request, and reduces the risk of wrenching of the slider. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a transversal sectional view of a sachet closing device along a slider cutting plane passing through two channels maintaining closing sections in remote position. 100 : Slider 120, 130 : Flanges 140 : Central wall 145, 146 : Flexible lips 200, 300 : Closing sections 216, 316 : Tapers.</p> |
