Benefits of technology

[0004] Various aspects of the present invention are directed to providing a flexible, innovative process for manufacturing consumable films. In one aspect, the invention provides a method of making a consumable film by forming a composition into a ribbon, feeding the ribbon to one or more dies, cutting the ribbon into sections, and drying the sections. In various aspects, the ribbon includes gelatin, starch, active ingredients, and/or various other effective materials. Additionally, the dies may be rotary or flat and may include a series of rollers and dies. The rollers may have alternating cutting surfaces. In another aspect, t

Embodiment Construction

[0010] In a conventional soft-gel manufacturing process, the gelatin mass and the center-fill medicinal mass are prepared separately. The gelatin mass may consist of a variety of materials including, for example, gelatin powder, glycerine, flavors, colors, and water. On the other hand, the center-fill, medicinal mass may include such compounds as oils, fats, waxes, excipients, and active ingredients. After the gelatin and medicinal masses are produced, they are transferred to a soft-gel encapsulator. In a typical encapsulation operation, molten gelatin is pumped to the encapsulator and two thin ribbons are formed on opposing sides of the encapsulator. These two ribbons then pass over a series of rollers and over a set of dies that determine the size and shape of the capsules. The medicinal mass, or fill, is fed to a positive displacement pump, which accurately transfers a predetermined amount of the fill and injects it between the two gelatin ribbons prior to the ribbons being seale...

Abstract

The present invention relates to consumable film products and a method for producing same. More particularly, one aspect of the invention provides a method of making a consumable film by forming a composition into a ribbon, feeding the ribbon to one or more dies, cutting the ribbon into sections, and drying the sections. One or more ribbons may be simultaneously treated. The dies of the invention may be configured to produce an array of variously shaped products having a thickness of less than about ⅛″. Another aspect of the invention provides single-layer films and multiple-layer films produced according to the disclosed methods.

Description

[0001] This application claims priority to Provisional Patent Application 60 / 563,610, filed Apr. 20, 2004.FIELD OF THE INVENTION [0002] The present invention relates to fast-dissolving, orally consumable films, which may be used to deliver pharmaceutical agents, breath deodorizing agents, antimicrobial agents and salivary stimulants to the oral cavity. In general, the invention relates to a process of making and providing consumable films. DESCRIPTION OF RELATED ART [0003] Consumable films and methods to produce these films are generally known. These existing processes require extensive, dedicated equipment including mixing, casting, and drying devices. SUMMARY OF THE INVENTION [0004] Various aspects of the present invention are directed to providing a flexible, innovative process for manufacturing consumable films. In one aspect, the invention provides a method of making a consumable film by forming a composition into a ribbon, feeding the ribbon to one or more dies, cutting the ri...
