First Claim
Patent Images
1. An oral product, comprising a body that is wholly receivable in an oral cavity, the body comprising:
- a mouth-stable polymer matrix comprising one or more mouth-stable polymers, the one or more mouth-stable polymers comprising polyurethane, wherein the body comprises at least 60 weight percent of the one or more mouth-stable polymers;
at least 10 weight percent of exhausted tobacco fibers embedded in the mouth-stable polymer matrix that together form a fiber-polymer matrix, the exhausted tobacco fibers having an average fiber size of less than 200 micrometers; and
an additive dispersed and absorbed in the fiber-polymer matrix such that the additive is released from the body when the body is received within the oral cavity and exposed to saliva, wherein the exhausted tobacco fibers form channels extending from one surface of the oral product to an opposite surface of the oral product in the mouth-stable polymer matrix comprising pores, the pores having diameters of 60 microns or less, the additive comprising nicotine or a derivative thereof; and
wherein the body has a compressibility @250 N of between 45% and 90% and a percentage of springiness of between 75% and 90%.

Abstract
An oral product includes a body that is wholly receivable in an oral cavity. The body includes a mouth-stable polymer matrix, exhausted tobacco fibers embedded in the mouth-stable polymer matrix, and an additive dispersed in the mouth-stable polymer matrix. The oral product is adapted to release the additive from the body when the body is received within the oral cavity and exposed to saliva.

18. An oral product, comprising a body that is wholly receivable in an oral cavity, the body comprising:
-
at least 60 weight percent of one or more mouth-stable polymers, the one or more mouth-stable polymers comprising polyurethane, the one or more mouth-stable polymers forming a mouth-stable polymer matrix; at least 10 weight percent of exhausted tobacco fibers embedded in the mouth-stable polymer matrix to form a fiber-polymer matrix, the exhausted tobacco fibers having an average fiber size of less than 200 micrometers; and an additive dispersed and absorbed in the fiber-polymer matrix such that the additive is released from the body when the body is received within the oral cavity and exposed to saliva, wherein the exhausted tobacco fibers have a length of about 0.1 inches up to about 1 inch and wherein a portion thereof forms channels extending from one surface of the oral product to an opposite surface of the oral product in the mouth-stable polymer matrix comprising pores, the pores having diameters of 60 microns or less, the additive comprising nicotine or a derivative thereof; wherein the body has a compressibility @ 250 N of less than 95%. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 32)

- 26. An oral product, comprising a body that is wholly receivable in an oral cavity, the body being formed by extruding a mixture of polyurethane and exhausted tobacco fibers to create a fiber-polymer matrix in which the exhausted tobacco fibers are embedded in the mouth-stable polymer matrix, the body comprising at least 60 percent weight of polyurethane and at least 10 percent weight of the exhausted tobacco fibers, the body further comprising an additive dispersed and absorbed in the fiber-polymer matrix such that the additive is released from the body when the body is received within the oral cavity and exposed to saliva, the additive comprising nicotine or a derivative thereof, wherein the body having a compressibility @ 250 N of less than 95% and a percentage of springiness of at least 20%, the body comprising between 40 and 80 weight percent of polyurethane and at least 10 weight percent of the exhausted tobacco fibers, wherein the exhausted tobacco fibers have a length of about 0.1 inches up to about 1 inch and wherein a portion thereof forms channels extending from one surface of the body to an opposite surface of the body, wherein the mouth-stable polymer matrix comprises pores, the pores having diameters of 60 microns or less.
