Method of manufacturing flavor pouches
A method of manufacturing a flavor pouch containing flavorant selected from one or more of tea, coffee, rose hips, honey, royal jelly, fruit extracts, mint, sweeteners, exotic flavors, and the like includes feeding a strip of fabric along a feed path, placing preselected amounts of flavorant material at spaced apart locations along the strip, forming flavor pouches by sealing portions of the strip together to enclose each preselected amount of flavorant material, and separating the flavor pouches from the strip. The pouches can have various shapes including crescent and oval shapes.
1. A method of making flavor pouches comprising the steps of:
feeding a non-woven strip along a generally horizontal feed path, the strip having a combination of natural and synthetic material with a basis weight of 5 to 25 g/m 2 , being a water-permeable, water-insoluble stain resistant polymer membrane that is insoluble in saliva, having structural integrity sufficient to retain a flavor carrier material when used in a human oral cavity, having a coating of barrier material which minimizes staining of one surface, and having a dissolvable film on the other surface;
forming the strip into an upwardly open U-shaped or V-shaped configuration such that the dissolvable film is within the U-shaped or V-shaped configuration;
placing preselected amounts of flavorant material at spaced apart locations along the formed strip on the surface having the dissolvable film, within the shaped configuration, the flavorant material being a solid material having a flavorant as a surface coating or incorporated in the material;
forming flavor pouches sized for placement in a human oral cavity by sealing portions of the strip together with a continuous arcuate seal having one or more corners to enclose each preselected amount of flavorant material by thermally welding overlapping regions of the strip;
separating the flavor pouches from a waste portion of the strip wherein the separating comprises punching the flavor pouches out of remaining portions of the strip; and
trimming overlapping portions of the strip to provide rounded corners.
2. The method of claim 1 , wherein the strip is non-woven polypropylene and the forming creates a pouch substantially free of oral irritants.
3. The method of claim 1 , wherein the placing comprises depositing on the strip a flavorant selected from the group consisting of tea, rose hips, honey, royal jelly, fruit extract, coffee, mint or mixture thereof.
4. The method of claim 1 , wherein the major dimension of each pouch is about 0.6 to 1.2 inches.
5. The method of claim 1 , wherein the flavorant comprises surface coated beads wherein the surface coating is soluble to effect timed release of the flavorant.
6. The method of claim 1 , further comprising folding the strip into a U-shaped or V-shaped strip while feeding the strip along the feed path and wherein the placing step includes placing preselected amounts of flavorant material at spaced apart locations along the U-shaped or V-shaped strip.
7. The method of claim 6 , wherein the sealing includes forming an arcuate weld seam and the separating comprises severing the strip along the arcuate weld seam.
8. A method of making flavor pouches comprising the steps of:
feeding a non-woven strip along a generally horizontal feed path, the strip having a combination of natural and synthetic material with a basis weight of 5 to 25 q/m 2 , being a water-permeable, water-insoluble stain resistant polymer membrane that is insoluble in saliva, having structural integrity sufficient to retain a flavor carrier material when used in a human oral cavity, having a coating of barrier material which minimizes staining of one surface, and having a dissolvable film on the other surface;
forming the strip into an upwardly open U-shaped or V-shaped configuration such that the dissolvable film is within the U-shaped or V-shaped configuration;
placing preselected amounts of flavorant material at spaced apart locations along the formed strip on the surface having the dissolvable film, within the shaped configuration, the flavorant material being a solid material having a flavorant as a surface coating or incorporated in the material;
forming rounded flavor pouches sized for placement in a human oral cavity by sealing portions of the strip together with a continuous arcuate seal having one or more corners to enclose each preselected amount of flavorant material by thermally welding overlapping regions of the strip;
separating the rounded flavor pouches from the strip wherein the separating comprises punching the flavor pouches out of remaining portions of the strip; and
trimming overlapping portions of the strip to provide rounded corners.
9. The method of claim 8 , wherein the web is non-woven polypropylene.
10. The method of claim 8 , wherein the placing comprises depositing on the strip a flavorant selected from the group consisting of tea, rose hips, honey, royal jelly, fruit extract, coffee, mint or mixture thereof.
11. The method of claim 8 , wherein the major dimension of each pouch is about 0.6 to 1.2 inches.
12. The method of claim 8 , wherein the flavorant comprises surface coated beads wherein the surface coating is soluble to effect timed release of the flavorant.
13. The method of claim 8 , further comprising folding the strip into a U-shaped or V-shaped strip while feeding the strip along the feed path and wherein the placing step includes placing preselected amounts of flavorant material at spaced apart locations along the U-shaped or V-shaped strip.
14. The method of claim 13 , wherein the sealing includes forming an arcuate weld seam and the separating comprises severing the strip along the arcuate weld seam.
