Label holder for closing and sealing bags and the like, and security seal suitable for use therewith

Label holder for the closure and sealing of bags, comprising first and second generally planar portions of substantially corresponding shapes, each of said portions having first and second opposite edges, third and fourth opposite edges, an outer surface and an inner surface, a hinge interconnecting said first edges so that said second portion may be doubled over said first portion to a closed configuration of the label holder with said inner surfaces facing each other, means for permitting the fixture of the ends of a length of cord within the interior of said label holder when in the closed configuration and means permitting the closure and sealing of the label holder in said closed configuration, said means for permitting the closure and sealing of the label holder comprising:

• a) a first protuberance formed on said inner surface of said first portion adjacent a corner thereof where said second and third edges of said first portion meet, said first protuberance being formed with a first substantially rectangular opening;
• b) a second protuberance formed on said inner surface of said first portion adjacent a corner thereof where said second and fourth edges of the first portion meet, said second protuberance being formed with a second substantially rectangular opening directed substantially towards said first protuberance;
• c) third and fourth openings formed through said second portion in correspondence with the respective said first and second protuberances so that, in said closed configuration of the label holder, said first and second protuberances pass through said third and fourth openings to project beyond said outer surface of said second portion;
• and
• d) a third protuberance formed on the outer surface of said second portion, positioned between said third and fourth openings, closer to said fourth opening and laterally of said second opening in the closed configuration of the label holder, said third protuberance being provided with a first stop surface parallel to and facing said outer surface of said second portion at a height corresponding to the upper limit of said second opening in the closed configuration of the label holder, and extended at least partially across the width of said second opening but displaced therefrom towards said third opening.
