Abstract Fastening means for a pair of flaps or the like are provided having first and second ferromagnetic plates, an elongated ferromagnetic element of cross-sectional area smaller than the area of the surfaces of either plate affixed at one end thereof substantially normal to a surface of the first of the plates, and magnetic means affixed in close proximity to the elongated element along a substantial portion, but not all, of its length. It is also contemplated that the above elements will be mounted by means of first and second thermoplastic mounting elements upon a pair of thermoplastic strips, which strips are affixable to facing surfaces of the flaps, in such a way that the nonsecured end of the elongated element releasably lockably engages a surface of the second plate in flush abutting relation when the fastening means is in the closed position.
Magnetic fastening means for a pair of flaps or the like comprising a ferromagnetic plate having an upper surface and a lower surface, a ferromagnetic cup having peripheral walls and an end wall, the cross sectional area of said peripheral walls being no greater than the area of the upper surface of said plate, a magnet having a first surface and a second surface of opposite polarities and a height less than that of the peripheral walls of the ferromagnetic cup affixed within said cup such that its first surface lies against the end wall thereof, a pair of thermoplastic strips affixable to facing surfaces of the flaps, female mounting means affixed to one of said strips holding said plate substantially parallel to said strip, and male fastening means affixed to the other of said strips holding said ferromagnetic cup such that the end wall thereof is substantially parallel to said other strip and such that said peripheral walls thereof may releasably engage said plate.
