Abstract: A magnetic strap fastener for use with existing strapped articles without modification is presented. The fastener includes first and second fastener parts for attaching to a complementary engagement arrangement on first and second strap ends. The first and second fastener parts are detachably engageable with each other by magnetic coupling or attraction and include complementary engagement devices for detachable engagement with the corresponding complementary engagement arrangement on the strap ends. Such a fastener is advantageous because it offers the benefits of magnetic fasteners and is at the same time readily attachable to an article having strap ends with an existing pair of complementary engagement devices.

Abstract: The present invention relates to a magnetic button that is waterproof and washable and to the method for manufacturing the same. The magnetic button (1) according to the present invention comprises a button body (2), a magnet (7) and a steel plate (8) placed in the cavity (9) of said button body. The manufacturing method of the present invention comprises. Step A: manufacturing a button body (2) with non-magnetic material; step B: putting the magnet (7) and steel plate (8) into the cavity (9) of the button body; step C: the magnet and the steel plate are combined integrally and scaled in the button body (2) with a piece of sealing material (11) through the hot pressing process. The magnetic button of the present invention is waterproof and washable. When used on clothes, the buttons can be automatically aligned and match with each other. The button is best suited in the case where buttons are not easily unbuttoned with hands, for example, when hands are in gloves. It is particularly suited to children.

Abstract: A plastic magnetic button that is waterproof and washable incluses a button body, a magnet and a steel plate disposed inside the cavity of said button body. The method of manufacturing the magnetic button comprises step A: manufacturing a button body with non-magnetic material, step B: putting the magnet and steel plate into the cavity of said button body, and step C: injecting a resinoid into the cavity and sealing the magnet and steel plate completely inside the cavity and combining integrally after hardening. The magnetic button can be used on clothes, can automatically align and match each other and is best suited for the case where buttons are not easy to be unbuttoned with the hands, such as, when both hands are in gloves.
