Abstract
An energy discharge circuit includes a high-power ultracapacitor 4 for providing pulses of electrical energy to a sealer 8 in an apparatus for sealing a plastic bag 38. The ultracapacitor 4 is charged by a power supply 30 and discharges the stored energy to the sealer 8, thereby enabling the sealing apparatus to seal the plastic bag 38 without the need for a high energy continuous electrical power source.
Claims37
An apparatus for sealing at least two plastic layers, comprising:
- (a) a power supply input capable of being supplied with an electrical energy;
- (b) an ultracapacitor coupled to store the electrical energy received by the power supply input;
- (c) a discharge circuit coupled to the ultracapacitor to discharge the electrical energy stored in the ultracapacitor;
- and
- (d) a sealer coupled to receive the electrical energy from the discharge circuit, the sealer capable of sealing the at least two plastic layers together upon a single discharge of the ultracapacitor.

An apparatus for sealing at least two plastic layers, comprising:
- (a) a power supply input capable of being supplied with an electrical energy;
- (b) an ultracapacitor coupled to store the electrical energy received by the power supply input;
- (c) a discharge circuit coupled to the ultracapacitor, the discharge circuit including a sealer for sealing the at least two plastic layers together;
- and
- (d) a switch connected between the power supply input, the ultracapacitor and the discharge circuit, the switch adapted to occupy a first position where the ultracapacitor is charged with the electrical energy from the power supply input, and a second position where the electrical energy stored in the ultracapacitor is discharged to the sealer, the switch moving between the first and second positions once for the sealer to seal the at least two plastic layers together.
