Abstract
Abstract The invention is an improvement over my copending application Ser. No. 951,569 filed Oct. 15, 1978 now U.S. Pat. No. 4,223,423, granted Sept. 23, 1980, and relates to a sealing device, which is particularly useful with a receptacle, such as a cloth bank bag for containing money or currency. The sealing device comprises a single strip or band of material made of metal or plastic and formed with teeth or serrations, which extend from one side of the band and includes locking projections engaging with the teeth or serrations in an improved manner for securing the band in its closed position. The locking teeth are stamped, or otherwise formed in the material near one end of the band, so that the other end of the band may be inserted through slits in the band, whereby a number of teeth engage with locking elements when the band is tightened around the neck of the bag. Movement of the end of the band is thereby prevented in the direction which would unlock the seal but is freely permitted in the other direction for the extent of the teeth so that a tight seal may be accomplished. Once sealed, the sealing device cannot be released without tearing or mutilating the bag material or damaging the sealing device.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
369 words
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 first substantially rectangular panel formed in the band and extending outwardly from one side of the band, a transverse slit for receiving one free end of the band when the device is assembled, a second substantially rectangular panel formed in the band and extending outwardly from the band in the opposite direction to the first panel, a window formed centrally of the first panel provided with a pair of transversely extending edges, a reversely bent tooth formed on one of the said window edges, a pair of transversely extending slits formed at the edges of said panel, certain of said individual teeth on the band engaging with one transverse edge of said panel, one of said teeth engaging with the reversely bent tooth on said one transverse edge of said window and one transverse edge of said depression when the device is assembled.
Claim 2
Dependent Claim
369 words
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 first substantially rectangular panel formed in the band and extending outwardly from one side of the band, a transverse slit for receiving one free end of the band when the device is assembled, a second substantially rectangular panel formed in the band and extending outwardly from the band in the opposite direction to the first panel, a window formed centrally of the first panel provided with a pair of transversely extending edges, a reversely bent tooth formed on one of the said window edges, a pair of transversely extending slits formed at the edges of said panel, certain of said individual teeth on the band engaging with one transverse edge of said panel, one of said teeth engaging with the reversely bent tooth on said one transverse edge of said window and one transverse edge of said depression when the device is assembled.
Claim 3
Dependent Claim
36 words
A sealing device as claimed in claim 1 wherein a portion of said tooth engaging with said reversely bent tooth on the edge of said window is concealed beneath said panel when the device is assembled.
Claim 4
Dependent Claim
38 words
A sealing device as claimed in claim 1 or 2 including penetrating means on the band for penetrating the material of the bag when the sealing device is assembled to preclude stripping the sealing device from the bag.
