Device intended for the closure of bags which includes resources that resist the pulling-off of a slider, and bag that is so equipped

摘要

This present invention concerns a closure assembly that has two complementary elements ( 200, 250 ) which are capable of being successively joined and separated, and a slider ( 100 ) that includes a base ( 110 ), two lateral cheeks ( 120, 130 ), a low central ridge ( 140 ) and a soleplate ( 142 ) connected to the low central ridge ( 140 ), characterised by the fact that at least one of the two elements ( 200, 250 ) has, on its inside surface, a structure ( 300 ) that is capable of being pressed against the soleplate ( 142 ) under the effect of a pulling force so that, under the effect of this force, the said element ( 250 ) tends to be flattened against the associated lateral cheek ( 130 ) of the slider.
