Economical and improved pull apart fragrance sampling device constructed of a film to film laminate. The mechanism for release of fragrance is accomplished by providing a microcapsule layer between a top ply and a bottom ply, which upon drying holds the overlying plies together, the microcapsules rupture upon peeling the top ply from the bottom ply, the fragrance is thereby released. A sampler produced as disclosed provides greater stability and shelf life than a paper sampler product while dramatically reducing manufacturing and raw material costs due to it's construction. The sampler provides the maximum flexibility in use and manufacture at a minimum cost.

The invention claimed is: 1. A pull apart device comprising: a top portion having an inside surface comprising polystyrene, a polystyrene blend or a polystyrene coated substrate, a bottom portion having an inside surface comprising polystyrene, a polystyrene blend or a polystyrene coated substrate;
The invention claimed is: 1. A pull apart device comprising: a top portion having an inside surface comprising polystyrene, a polystyrene blend or a polystyrene coated substrate, a bottom portion having an inside surface comprising polystyrene, a polystyrene blend or a polystyrene coated substrate; and a gelatin-based microcapsule layer deposited by conventional means onto an inside surface of either the top or bottom portion, wherein the microcapsules adhere to the bottom and top surfaces such that the capsule coating bonds the overlying surfaces together, the bond between the top and bottom surfaces can be broken by separating the plies, whereby the microcapsules are substantially compromised and release a material contained therein. 2. A pull apart device according to claim 1, wherein the microcapsule coating contains other additives. 3. A pull apart device according to claim 2, produced in the form of a pressure sensitive backed label which may be affixed to any printed matter, packaging or any delivery vehicle. 4. A pull apart device according to claim 2, distributed in the form of a laminated card manufactured in a single or multiple operation with or without the need for subsequent affixing to another delivery vehicle. 5. A pull apart device according to claim 2, wherein the polystyrene surface is over-laminated with a polymeric, paper or composite stock including metalized films, holographic films or preprinted stock. 6. A pull apart device according to claim 4, wherein a single continuous polystyrene substrate is folded over onto itself before or after laminating to another substrate such as a paper of film. 7. A pull apart device according to claim 2, wherein the microcapsules contain a fragrance, which is released upon separation of the overlying plies. 8. A pull apart device according to claim 2, wherein the additives comprise adhesives and viscosifiers. 9. A pull apart device comprising: a first ply having an inside surface comprising a coated paper, a second ply having an inside surface comprising polystyrene, a polystyrene blend or a polystyrene coated substrate; and a microcapsule layer comprising microcapsules which are made with a wall material having at least some degree of permeability deposited by conventional means onto an inside surface of either the top or bottom portion, wherein the microcapsules adhere to the bottom and top surfaces such that the capsule coating bonds the overlying surfaces together, the bond between the top and bottom surfaces can be broken by separating the plies, whereby the microcapsules are substantially compromised and release a material contained therein. 10. A pull apart device comprising: a top portion having an inside surface comprising polystyrene, a polystyrene blend or a polystyrene coated substrate, a bottom portion having an inside surface comprising polystyrene, a polystyrene blend or a polystyrene coated substrate; and a microcapsule layer comprising microcapsules made with a wall material having at least some degree of permeability deposited by conventional means onto an inside surface of either the top or bottom portion, wherein the microcapsules adhere to the bottom and top surfaces such that the capsule coating bonds the overlying surfaces together, the bond between the top and bottom surfaces can be broken by separating the plies, whereby the microcapsules are substantially compromised and release a material contained therein. 11. A pull apart device according to claim 1, wherein the gelatin based microcapsule layer is a coacervate of gelatin and at least one material selected from the group consisting of gum arabic, polyphosphate, alginate and carboxymethylcellulose.
