A button back which makes it possible to form the front surface of a button to be a circular shape; a shell cap hard to be rotated; and an umbrella part hard to be deformed. The button back is made of metal, including a cylindrical part and an umbrella part extending radially outward from one axial end of the cylindrical part. The umbrella part includes a first bending part which extends radially outward from the one axial end of the cylindrical part and then bends on the opposite side of the cylindrical part. An outer periphery, including a radially outer end, of the first bending part has a polygonal shape including at least three corners and sides which extend between two circumferentially adjacent corners. The umbrella part includes flat plates extending radially outward from the radially outer end, corresponding to the sides, of the first bending part.

Concepts provided are directed to a flexible button that is bendable when exposed to a force. The flexible button in accordance herein has a tapered perimeter portion such that a thickness of a peripheral edge of the perimeter portion is less than a thickness of remaining portions of the flexible button. The low-profile of the flexible button allows the flexible button to easily slip through a respective button hole and to be more easily gripped by a user. Further, the flexible button in accordance with aspects herein provides higher breathability than conventional buttons of the same size by having voided portions on its perimeter portion.

The invention relates to a monitor device for monitoring the closed or open state of an article, the monitor device being in the form of an electronic circuit comprising a first closure system (9) comprising first and second electrically conductive elements (6, 7) that are electrically connectable and disconnectable relative to each other, with at least the first element (6) comprising a hollow body (60); an electrical power supply (5) housed in the hollow body (60), a second closure system ( ) comprising a first terminal ( ) and a second terminal ( ). The monitor device also comprises a detector-and-signaling device comprising both a detector module configured to be powered by the power supply (5) when the first closure system (9) is in the closed state and to detect the open or closed state of the second closure system, and also a signaling module configured to issue a signal as a function of the open or closed state of the second closure system as detected by the detector module.

A clasp assembly is provided. The clasp assembly includes a first clasp member, a second clasp member, a first magnet, and a metallic component. The first clasp member defines a first cavity sized to receive a first portion of a zipper, and defines a first portion extending over the first cavity. The second clasp member defines a second cavity sized to receive a second portion of the zipper, and defines an overhang. The first magnet is secured to one of the first portion of the first clasp member and the overhang of the second clasp member. The metallic component is secured to another of the first portion of the first clasp member and the overhang of the second clasp member. The overhang is sized to receive the first portion of the first member to align the first magnet and the metallic component for magnetic interaction therebetween.
