Patent ID: 8071123

Claim:
A method for producing an orally administrable edible agent of laminate film form, the method comprising: forming a plurality of orally administrable edible agent layers, wherein each orally administrable edible agent layer has a predetermined thickness and is formed on a surface of a respective resin film by coating and drying; joining together two orally administrable edible agent layers so that orally administrable edible agent layer surfaces face each other and the orally administrable edible agent layers are sandwiched between the resin films of the two orally administrable edible agent layers, and pressurizing the resin films at back surfaces by a pair of press rolls so as to bond the orally administrable edible agent layers together such that ingredients of each of the orally administrable edible agent layers do not permeate the other of the orally administrable edible agent layers, wherein the orally administrable edible agent layers include the same ingredients or different ingredients; and delaminating only one of the two resin films by conveying the two resin films sandwiching the bonded orally administrable edible agent layers in a substantially tangential direction at a pressurization zone of the pair of press rolls, and drawing only one of the two resin films sandwiching the bonded orally administrable edible agent layers in a direction different from the conveying direction along a peripheral surface of a delamination roll disposed in the conveying direction while continuously conveying the other resin film retaining the bonded orally administrable edible agent layers in the conveying direction.
