Abstract
A method of forming dual layer water soluble packets includes drawing a base film into a cavity of a mold, drawing air through openings in the base film, metering an amount of a first product of a first color onto the base film in the cavity, metering an amount of a second product of a second color onto the amount of the first product, and, sealing a lid film to the base film.
Claims21
A system for forming dual layer water soluble packets, comprising:
- a plurality of cavities operatively engaged to a motor for moving the cavities;
- a base film supply roll configured to supply a base film to cover the plurality of cavities;
- a laser to form openings in the base film;
- a vacuum source to draw the base film into at least one cavity of the plurality of cavities and
- draw air through the openings in the base film;
- a first product feeder for metering an amount of a first product of a first color onto the base film in the at least one cavity;
- a second product feeder for metering an amount of a second product of a second color onto the amount of the first product
- a lid film supply roll to supply a lid film onto the base film;
- and
- a lid film roller for sealing the lid film to the base film.

A packet forming assembly for forming dual layer water soluble packets, comprising:
- a plurality of cavities operatively engaged to a motor for moving the cavities;
- a base film supply roll configured to supply a base film to cover the plurality of cavities;
- a laser to form openings in the base film;
- a vacuum source configured to apply vacuum to the lower side of the base film to draw the base film into at least one cavity of the plurality of cavities and;
- draw air through the openings in the base film;
- a first product feeder meter for metering an amount of a first product onto an upper side of the base film in the at least one cavity while applying the vacuum to the lower side of the base film;
- and
- a second product feeder meter for metering an amount of a second product onto the amount of the first product while applying the vacuum to the lower side of the base film.

A system for forming dual layer water soluble packets, comprising:
- A laser configured to forming openings in a base film;
- a vacuum source configured to apply a suction force to draw the base film into a cavity of a mold;
- a first product feeder configured to deposit an amount of a first product of a first color onto a first side of the base film in the cavity while applying the suction force to a second side of the base film;
- a second product feeder configured to meter an amount of a second product of a second color onto the amount of the first product while applying the suction force to the second side of the base film;
- and
- a lid film roller configured to seal a lid film to the first side of the base film;
- wherein the openings are formed by the laser after the base film has been stretched into the cavity and before the amount of the first product is deposited onto the first side of the base film in the cavity.
