Claims
- 1. A sample holder comprising:
- a planar, flexible base ply having a hole therethrough;
- a planar, flexible closure ply affixed to the base ply, the hole and the closure ply thereby defining a retaining cavity for the sample;
- a planar, leak-proof, flexible film ply removably affixed to the base ply covering the hole and enclosing the sample in the retaining cavity between the planar, flexible closure ply and the planar, leak-proof, flexible film ply; and
- a uniform layer of base ply adhesive between the planar, leak-proof, flexible film ply and the planar, flexible base ply affixing the planar, leak-proof, flexible film ply to the planar, flexible, base ply.
- 2. A method of a making a sampler comprising the steps of:
- punching at least one hole through a laminate sheet, the laminate sheet comprising a base ply, a base ply adhesive on a first side of the base ply and a backing ply covering the base ply adhesive;
- affixing a closure ply to a second side of the foam ply, opposite the first side, for covering the punched hole through the laminate sheet and a defining retaining cavity in the laminate sheet;
- depositing a sample in the retaining cavity;
- removing the backing ply from the base ply to expose the base ply adhesive on the first side of the base ply;
- affixing a film ply to the first side of the foam ply to cover and enclose the retaining cavity.
- 3. The method of claim 2 further comprising applying an application adhesive on one side of the film ply opposite the first side of the base ply, and then affixing a carrier ply over the application adhesive, the carrier ply being removable to expose the application adhesive when the substance applicator is to be affixed to a carrier.
- 4. The method of claim 2 further comprising applying an application adhesive on one side of the closure ply opposite the second side of the base ply, and then affixing a carrier ply over the application adhesive, the carrier ply being removable to expose the application adhesive when the sampler is to be affixed to a carrier.
- 5. The method of claim 2 further comprising cutting at least one individual region from the composite laminate, each having at least one retaining cavity with the sample contained therein.
- 6. A method of making a sampler comprising the steps of:
- punching at least one hole through a laminate sheet, the laminate sheet comprising a base ply, a base ply adhesive on a first side of the base ply and a backing ply covering the base ply adhesive and a liner ply adhesive on the second side of the base ply and a liner ply covering the base ply adhesive:
- removing the liner ply and affixing a closure ply to the liner ply adhesive for covering the punched hole through the laminate sheet and defining a retaining cavity in the laminate sheet;
- depositing a sample in the retaining cavity;
- removing the backing ply from the base ply to expose the base ply adhesive on the first side of the base ply;
- affixing a film ply to the first side of the base ply to cover and enclose the retaining cavity.
