Abstract

The present invention provides a reverse opening type slide fastener in which an upper slider and a lower slider can be held at a bottom end of a box pin when an insert pin is pulled out of the upper slider and the lower slider and separated therefrom. The reverse opening type slide fastener (10) has a separable bottom end stop (22) including a box pin (40) provided consecutively from a bottom end of a right element row (13) disposed on a side edge of a right fastener stringer (17), an insert pin (30) provided consecutively from the bottom end of a left element row (12) disposed on a side edge of a left fastener stringer (16), an upper slider (50) which enables the slide fastener to be opened upward and a lower slider (60) which enables the slide fastener to be opened in a reverse direction. A stopper (46) for preventing the lower slider (60) from slipping off is provided at the bottom end of the box pin (40). A first engaging portion (44) is formed on an opposite side edge opposite to the insert pin (30) of the box pin (40) and a second engaging portion (34) is formed on an opposite side edge opposite to the box pin (40) of the insert pin (30) so as to position the insert pin (30) in a downward direction when the second engaging portion engages the first engaging portion (44). A projecting portion (48) which makes contact with the inner face of the blade of the upper slider (50) so as to suppress a free sliding of the upper slider (50) is formed on at least any one of a front side face and a rear side face opposite to the inner face of the blade of the upper slider (50) of the box pin (40).

Description

technical field [0001] The present invention relates to a reverse opening zipper that can be opened upward and in the opposite direction while being detachable and engaging. Background technique [0002] As a slide fastener for opening or closing the left and right front bodies of clothes, a separable / snap type slide fastener having a seat tube and an insertion tube on the bottom of an element row has been used. [0003] In a common zipper with a detachable bottom stop, the prongs are formed at the bottom end of the row of elements on one side, while the socket into which the prongs will be inserted is fixedly set through the seat tube and removed from the elements on the other side. The bottom ends of the rows are set consecutively. This kind of zipper with detachable bottom stop is configured like this: when the slider is pulled down to the lowest position where the slider contacts the socket, the insertion tube can be moved out of the socket and the slider or inserted in...
