Abstract: A waterproof closure system 1 including a plate 20 having a periphery 21 and at least one closure member 30 which can be fitted around the periphery of the plate so that when they are joined the closure member forms a border around the periphery of the plate. The closure member has at least two elements 30a,30b separated by a split 41 with there being a locking means, for example having a male part 42 provided on a first element on one side of said split and a female part 44 provided on a second element on the other side of said split that can lock the two elements together o closing the split and tightening the closure member around the periphery of the plate thereby locking a mouth of a bag placed around the plate between the plate periphery and closure member.

Abstract: The present invention provides an apparatus for protecting a device from water damage. The apparatus is capable of being repeatedly opened and then hermetically sealed even when the device has a wire that must be extended outside of the apparatus. The present invention comprises a housing having at least two members that, when juxtaposed and clamped, form a dry interior region. More specifically, each member includes a pair of gaskets that together define the dry interior region and substantially form a hermetic seal about a pouch or container. The apparatus includes a portal through which the wire may extend from a device inside the pouch or container to the outside and a slide mechanism that adjust a gasket around the wire to maintain the dry interior region. The slide mechanism forms a hermetic seal around the wire so that the opening in the pouch from which the wire extends is hermetically sealed. If no wire is present, the slide mechanism may be adjusted to maintain the hermetic seal.
