A wire mesh rivet (13) is provided which is used to produce a wire mesh isolator (11) in a bore (9) of a substrate such as a heat shield (7) for a vehicle exhaust system. The rivet (13) comprises a unitary wire mesh structure (19) which has a collar (15) and a shank (17). The collar (15) has a higher density than the shank (17), e.g., the collar (15) has the density of the finished isolator (11). The rivet (13) is formed into the finished isolator (11) by compressing the shank (17) to form a second collar, while restraining the original collar (15) from substantially changing its shape. The rivet (13) can include a metal insert (23) which prevents the wire mesh of the finished isolator (11) from experiencing high levels of compression when the substrate is fastened to its supporting structure. The rivets (13) can be carried by a dispensing strip (31) and can be formed into the finished isolator (11) using forming equipment (39) whose dimensions are compatible with the limited space available with some substrates.

An electronic cigarette packing case and a method for manufacturing the electronic cigarette packing case, the electronic cigarette packing case comprising a case body, and a hook arranged on a case body side wall, wherein the hook is rotationally connected to the case body side wall, and an outer surface of the case body side wall is provided with a first accommodation space which is shaped to match the hook and used for accommodating the hook in a non-use state; and the outer surface of the case body side wall is further provided with a recessed portion for removing the hook from the first accommodation space, the recessed portion is a notch provided at an edge of the first accommodation space. The present invention enables an electronic cigarette to be conveniently displaced, and ensure that the hook will not be easily fractured, damaged or bending deformed during transportation.
