Bank bag sealer

A sealing device for a receptacle having at least one open end, which receptacle consists at least in part of deformable material adjacent the open end thereof, so that the material may be gathered together to form a neck, said sealing device comprising a relatively thin band of flexible material which is of sufficient strength that it is manually severable only by cutting through the same, said band comprising an elongated flat body portion and a pair of end portions at the extremities thereof, means for tightly securing the body portion of said band circumferentially about the neck of said receptacle adjacent to said end, with said end portions extending outwardly from the circumferential body portion, means on said band for preventing the seal from being opened to gain access to said receptacle without severing or damaging the band, a plurality of projections formed on one side of the body portion of the band at substantially right angles to the length thereof and bent in one direction toward one end of the band, and locking means adjacent said one end of the band for engaging one or more of said projections, said locking means and said projections permitting relative movement of said band in one direction relative to said locking means and substantially preventing relative movement thereof in the other direction, said locking means comprising a pair of oppositely formed panels extending at substantially right angles to the length of said strip to provide a pair of slits in said band through which the other end of the band is inserted a sufficient distance for at least two of said projections to engage with the edge of one of said panels and with an edge in the strip formed by the other of said panels being locked in position thereby to prevent substantial movement of said second end of the band away from the locking means.
