Abstract
This present invention concerns a closure assembly that has two complementary elements which are capable of being successively joined and separated, and a slider that includes a base, two lateral walls, a low central ridge and a soleplate connected to the low central ridge, characterized by the fact that at least one of the two elements has, on its inside surface, a structure that is capable of being pressed against the soleplate under the effect of a pulling force so that, under the effect of this force, the said element tends to be flattened against the associated lateral wall of the sider.

A closure assembly that includes two complementary elements (200), (250) that are configured to be successively joined and separated, and a slider (100) that includes a base (110), two lateral walls (120, 130), a low central ridge (140) extending from the base (110) parallel to the two lateral walls (120, 130), wherein the low central ridge (40) comprises a soleplate (142) that extends transversally from a free end of the low central ridge (140), wherein
- at least one of the two elements (250) has a rib (300) that extends transversally to the at least one of the two elements (250) from an internal face (252) of a backing strip (254) of said at least one of the two elements (250) towards the second of the two elements, wherein said rib (300) and is adjacent to the soleplate (142) and comprises a tapered end configured to press against the soleplate (142) under the effect of a pulling force on the slider, so that when the tapered end of the rib (300) is pressed against the soleplate due to the pulling force on the slider, the backing strip that bears the at least one element (250) which comprises the rib (300) on its inside surface tends to be flattened against the associated lateral wall (130) of the slider and prevents withdrawal of the slider from the at least one of the two complementary elements (250), wherein
- both of the complementary elements (200) and (250) extend between the base and the soleplate,
- the rib extends beneath at least one of the two complementary elements (250) between said at least one complementary element (250) and the soleplate (142), and
- the portion of the soleplate (142) which extends in the area of an upper surface (1420) against which the rib (300) comes into abutment is smaller than the portion of the soleplate which is adjacent to said at least one complementary element (200).
A closure assembly comprising:
- two complementary elements being capable of successively joined and separated;
- a slider that includes a base, two lateral walls, a central ridge extending from the base parallel to the two lateral walls, wherein the central ridge comprises a soleplate that extends transversally from a free end of the central ridge, wherein
- at least one of the two elements has, on its inside surface, a rib that extends transversally to the at least one of the two elements from an internal face of a backing strip of said at least one of the two elements towards the second of the two elements, wherein said rib is adjacent to the soleplate and comprises a face wherein the whole of the face of the rib presents a deviation in relation to an opposing face of the soleplate that is adapted to press against the soleplate, under the effect of a pulling force on the slider, so that when the face of the rib is pressed against the soleplate due to the pulling force on the slider, the backing strip that bears the at least one element which comprises the rib on its inside surface tends to be flattened against the associated lateral all of the slider and prevents withdrawal of the slider from the complementary elements.
A closure assembly comprising:
- two complementary elements configured to be successively joined and separated;
- a slider that includes a base, two lateral walls, a central ridge extending from the base parallel to the two lateral walls, wherein the central ridge comprises a soleplate that extends transversally from a free end of the central ridge, wherein
- at least one of the two complementary elements has, on its inside surface, a rib that extends transversally to the at least one of the two complementary elements from an internal face of a backing strip of said at least one of the two complementary elements towards the second of the two elements, wherein said rib is adjacent to the soleplate and comprises a face facing the soleplate that extends from an internal face of a backing strip of the one of the two complementary elements to its free end at an angle greater than ninety degrees relative to the internal face, wherein the face is adapted to press against the soleplate under the effect of a pulling force on the slider, so that when the face of the rib is pressed against the soleplate due to the pulling force on the slider, the backing strip that bears the at least one complementary element which comprises the rib on its inside surface tends to be flattened against the associated lateral wall of the slider and prevents withdrawal of the slider from the complementary elements.
