Abstract
Systems and methods to form openings in water soluble packets are described. The system includes a packet forming assembly to form water soluble packets, and a laser to form one or more openings in the water soluble packets. The method includes forming openings in the water soluble packets with a laser. The openings permit air to escape from the packets. By allowing air to escape, the water soluble packets have improved packaging characteristics. The water soluble packets are packed more tightly with a product.
Claims24
A system to form openings in water soluble packets, comprising:
- a packet forming assembly to form water soluble packets, the packet forming assembly includes one or more cavities, a base film supply roll supplies a base film to cover the one or more cavities, a feed hopper meters an amount of a product into the one or more cavities over the base film, and a lid film supply roll supplies a lid film that is sealed to the base film;
- and,
- a laser to form one or more openings in the water soluble packets.
A system to form openings in water soluble packets, comprising:
- a rotating drum operatively engaged to a motor for rotating the drum;
- the drum comprising one or more of cavities;
- a base film supply roll to supply a base film to the drum to cover the one or more cavities;
- a feed hopper to meter an amount of a product into the one or more cavities over the base film;
- a lid film supply roll to supply a lid film to the drum;
- and,
- a laser to form openings in the base film, the lid film, or the water soluble packet.
A system to form openings in water soluble packets, comprising:
- a vertical form fill seal machine to form water soluble packets, the vertical form fill seal machine includes a hopper, a horn, a supply of film, and one or more sealing devices, wherein the film is positioned about an exterior surface of the horn, the hopper meters an amount of a product into the horn, and the one or more sealing devices seal the film closed to form the water soluble packets;
- and,
- a laser to form one or more openings in the water soluble packets.
A method of forming openings in water soluble packets, comprising:
- providing a packet forming assembly to form water soluble packets, the packet forming assembly comprising one or more cavities;
- covering the one or more cavities with a base film;
- feeding an amount of a product into the one or more cavities over the base film;
- sealing a lid film to the base film to form the water soluble packet;
- and,
- forming openings in the water soluble packets with a laser.
A method of forming openings in water soluble packets, comprising:
- drawing a base film into a cavity of a drum;
- metering an amount of a product onto the base film in the cavity;
- sealing a lid film to the base film;
- and,
- forming openings in the water soluble packets with a laser.
A method of forming water soluble packets, comprising:
- drawing a base film into a cavity of a drum;
- forming one or more openings in the base film with a laser;
- vacuuming air through the openings in the base film;
- metering an amount of a product onto the base film in the cavity;
- vacuuming the product into the base film;
- and,
- applying a lid film to the base film.
A laser assembly to form openings in water soluble packets, comprising:
- a laser;
- and,
- a controller, wherein the controller modulates pulses from the laser to direct the pulses at water soluble packets or a film forming water soluble packets.
