Abstract

Abstract A sealing device which is particularly for use with a receptacle such as a cloth bank bag for containing money or currency, in which a single strip or band of material is formed of metal or plastic stamped with projections or serrations extending from one side of the band and wherein locking projections are stamped in the material near one end of the band, so that the other end thereof may be inserted through slits formed by oppositely facing panels in the one end of the band, whereby one or more of the serrations are engaged and locked by edges of the locking projections which are provided by one set of the panels when the strip is tightened around the neck of the bag. Movement of the ends of the strips is thereby prevented in a direction which would unlock the seal but is freely permitted in the other direction for the extent of the serrations so that a tight seal may be accomplished. The material adjacent the panels is provided with sets of inwardly extending spikes to engage the material of the bag when the sealing device is in place and tightened, so that the sealing device may not be removed from the bag without tearing or destroying the same and thus immediately providing evidence of tampering or attempted pilferage. In the construction disclosed, the projections or serrations extend from one side of the band toward the receptacle to be sealed, such as the neck of a bank bag, thus covering and concealing the locking mechanism of the locking device and frustrating attempts to tamper therewith. In addition, a pair of transverse protuberances are included on the undersurface of one end portion of the band. The protuberances, which are preferably rounded, facilitate the movement of the body portion when the sealing device is tightened around the bag and provide for a space therebetween which allows insertion of a sharp tool, for example a knife, to sever and remove the sealing device from the bag without cutting the fabric of the bag.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 266 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, a plurality of serrations formed on the side of the flat body portion of the band which faces the receptacle when secured thereto, one end portion of the band being substantially flat, means on the other end of the band for cooperating with said serrations to lock the band in a circumferentially closed position when secured to the receptacle, said last means comprising a plurality of opposed panels forming slits therethrough of the band, certain of said edges being formed with surfaces to conform with at least a portion of the serrations when the one end of the band is inserted through said slits and the band is manually tightened about the neck of the receptacle, and transverse and spaced apart rounded protuberances formed on the extremity of said other end of the band on the side thereof opposite the serrations to provide a sliding bearing surface for the band when secured to the receptacle and also providing a space thereafter for the insertion of a cutting tool to afford removal of the band from the receptacle without injury to the receptacle.
Claim 2
Dependent Claim 266 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, a plurality of serrations formed on the side of the flat body portion of the band which faces the receptacle when secured thereto, one end portion of the band being substantially flat, means on the other end of the band for cooperating with said serrations to lock the band in a circumferentially closed position when secured to the receptacle, said last means comprising a plurality of opposed panels forming slits therethrough of the band, certain of said edges being formed with surfaces to conform with at least a portion of the serrations when the one end of the band is inserted through said slits and the band is manually tightened about the neck of the receptacle, and transverse and spaced apart rounded protuberances formed on the extremity of said other end of the band on the side thereof opposite the serrations to provide a sliding bearing surface for the band when secured to the receptacle and also providing a space thereafter for the insertion of a cutting tool to afford removal of the band from the receptacle without injury to the receptacle.
Claim 3
Dependent Claim 48 words
A sealing device as claimed in claim 1 including a plurality of sharp protuberances formed on said other end of the band on the same side thereof as said serrations and adapted to pierce the neck of said receptacle when the device is tightened about the neck thereof.
Claim 4
Dependent Claim 25 words
A sealing device as claimed in claim 2 wherein the plurality of sharp protuberances are spaced longitudinally of said other end portion of the band.
Claim 5
Dependent Claim 23 words
A sealing device as claimed in claim 3 wherein said protuberances are also spaced transversely of said other end portion of the band.
Claim 6
Dependent Claim 29 words
A sealing device as claimed in claim 1 wherein said one end of the band is provided with a bent portion to facilitate the insertion thereof through said slits.
Claim 7
Dependent Claim 170 words
A sealing device for an object to be sealed comprising a relatively thin band of flexible material which is of sufficient strength that 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, a plurality of serrations formed on the side of the flat body portion of the band which faces the object on which the sealing device is to be placed, one end portion of the band being substantially flat, and means on the other end of the band for cooperating with said serrations to lock the band in a circumferentially closed position when secured, said last means comprising a plurality of opposed panels having slits therethrough and having edges thereon extending transversely of the band, certain of said edges being formed with surfaces to conform with at least a portion of the serrations when the one end of the band is inserted through said slits and the band is manually tightened.
Claim 8
Dependent Claim 170 words
A sealing device for an object to be sealed comprising a relatively thin band of flexible material which is of sufficient strength that 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, a plurality of serrations formed on the side of the flat body portion of the band which faces the object on which the sealing device is to be placed, one end portion of the band being substantially flat, and means on the other end of the band for cooperating with said serrations to lock the band in a circumferentially closed position when secured, said last means comprising a plurality of opposed panels having slits therethrough and having edges thereon extending transversely of the band, certain of said edges being formed with surfaces to conform with at least a portion of the serrations when the one end of the band is inserted through said slits and the band is manually tightened.
Claim 9
Dependent Claim 32 words
A sealing device as claimed in claims 1 and 6 wherein the opposed panels having said serration engaging edges thereon face the object to be sealed when the band is assembled thereabout.
Claim 10
Dependent Claim 75 words
A sealing device as claimed in claim 6 wherein transverse and spaced apart rounded protuberances are formed on the extremity of said other end of the band on the side thereof opposite the serrations to provide a sliding bearing surface for the band when secured to the object, and also providing a space thereafter for the insertion of a cutting tool to afford removal of the band from the object without injury to the object.
