Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
186 words
Apparatus for the simultaneous and continuous production of a guarantee closure on a multiplicity of containers with closure caps each having a guarantee strip of plastics material separable along a desired tear line, said strip being positively shrink fitted on to the neck of the associated container by heating, comprising transport means for transporting the containers in a row along a predetermined feed path and for simultaneously rotating the containers about their own axes, at least one assembly for producing a flow of hot gas, provided along the feed path, a slot-like nozzle of said assembly disposed approximately at the level of the plane of movement of the guarantee strips, the outlet opening of said nozzle being directed toward the guarantee strips on said containers as they are moved therepast continuously in a row, while rotating about their own axes to thereby direct the hot gas against the guarantee strips, and a deflector for receiving hot gas from said nozzle after the hot gas has passed the guarantee strips and redirecting it back onto the region of the guarantee strips on the side opposite the nozzle.
Claim 2
Dependent Claim
186 words
Apparatus for the simultaneous and continuous production of a guarantee closure on a multiplicity of containers with closure caps each having a guarantee strip of plastics material separable along a desired tear line, said strip being positively shrink fitted on to the neck of the associated container by heating, comprising transport means for transporting the containers in a row along a predetermined feed path and for simultaneously rotating the containers about their own axes, at least one assembly for producing a flow of hot gas, provided along the feed path, a slot-like nozzle of said assembly disposed approximately at the level of the plane of movement of the guarantee strips, the outlet opening of said nozzle being directed toward the guarantee strips on said containers as they are moved therepast continuously in a row, while rotating about their own axes to thereby direct the hot gas against the guarantee strips, and a deflector for receiving hot gas from said nozzle after the hot gas has passed the guarantee strips and redirecting it back onto the region of the guarantee strips on the side opposite the nozzle.
Claim 3
Dependent Claim
54 words
Apparatus as defined in claim 1, wherein said transport means comprises a transport channel defined by side walls comprising a drivable transport screw on one side and a wall arranged parallel to the axis of the transport screw on the other side the bottom of said channel being formed by a drivable conveyor belt.
Claim 4
Dependent Claim
26 words
Apparatus as defined in claim 2, wherein said wall is prestressed by a spring device to clamp the containers between the transport screw and the wall.
Claim 5
Dependent Claim
34 words
Apparatus as defined in claim 1, wherein said deflector has an arcuately curved end portion located such that the guarantee strips on the containers move between said nozzle and said arcuately curved end portion.
Claim 6
Dependent Claim
56 words
Apparatus as defined in claim 4, wherein said deflector comprises a deflection plate which is connected to the top of the slot-like nozzle and extends over the feed path to cover the row of closure caps in a tunnel-like configuration, the deflection portion at the side remote from the nozzle extending substantially parallel to the nozzle.
Claim 7
Dependent Claim
26 words
Apparatus as claimed in claim 1 wherein said deflector includes a deflector surface located on the opposite side of the row of containers from said nozzle.
