The present invention relates to an animal chew toy comprising a first material including a body portion and one or more exposed regions comprising a second material, the material of the exposed regions at least partially occupying one or more blind holes in the body portion wherein the one or more
The present invention relates to an animal chew toy comprising a first material including a body portion and one or more exposed regions comprising a second material, the material of the exposed regions at least partially occupying one or more blind holes in the body portion wherein the one or more blind holes may include an undercut or die locked condition to aid in retaining the second material. The chew may be formed via a number of molding methods including those utilizing injection molding or extrusion techniques. The first and second materials may comprise edible compositions.

1. A method of manufacturing an animal chew comprising: molding a first material include a first shape comprising a first end portion, a second end portion, and a body portion between the first and second end portions, wherein: said first shape includes a die-locked recess between said first and sec
1. A method of manufacturing an animal chew comprising: molding a first material include a first shape comprising a first end portion, a second end portion, and a body portion between the first and second end portions, wherein: said first shape includes a die-locked recess between said first and second end portions, the die-locked recess including a first sidewall at least partially defined by the first end portion, a second sidewall at least partially defined by the second end portion, and a bottom surface at least partially defined by a surface of said body portion;said first shape further comprises a plurality of blind holes between said first and second sidewalls, each of said plurality of blind holes extending from said bottom surface of said die-locked recess and partially through a thickness of said body portion; andmolding a second material onto said first shape, such that the second material is within said die-locked recess of said first shape, at least a portion of the second material is within said blind holes, and at least a portion of the second material remains exposed, wherein following molding of said second material, said second material does not extend over said first and second end portions. 2. The method of claim 1 wherein said second material forms a hollow shape at least partially surrounding a portion of said body portion. 3. A method of manufacturing an animal chew comprising: molding a second material into one or more shapes having a plurality of protrusions;locating said one or more shapes in a mold for a body portion, said mold for said body portion defining a first shape comprising a first end portion, a second end portion, and a body portion between the first and second end portions, wherein: the first shape includes a die-locked recess between the first and second end portions, the die-locked recess including a first sidewall at least partially defined by the first end portion, a second sidewall at least partially defined by the second end portion, and a bottom surface defined at least in part by a surface of said body portion; andthe first shape further includes a plurality of blind holes between the first and second sidewalls, each of the plurality of blind holes extending from said bottom surface of said die-locked recess and partially through a thickness of said body portion; andmolding a first material around at least a portion of said one or more shapes to form said first end portion, second end portion, and body portion, such that at least a portion of said second material is within said die-locked recess, each of said plurality of protrusions is within a respective one of said plurality of blind holes, and at least a portion of said second material remains exposed, wherein following molding of said first material, said second material does not extend over said first and second end portions. 4. The method of claim 3 wherein said plurality of protrusions include at least one protrusion that includes an end, and which has a cross-sectional dimension at some location spaced a distance from the end that is less than the cross-sectional dimension at the end of the protrusion. 5. The method of claim 3 wherein said second material forms a hollow shape at least partially surrounding a portion of said first material forming said body portion. 6. The method of claim 3 wherein said one or more shapes further comprises a third material. 7. The method of claim 3 wherein first material has a volumetric shrinkage that is greater than said second material. 8. The method of claim 3 wherein said plurality of protrusions each extend from an inner surface of said one or more shapes of said second material; and at least one of said plurality of protrusions has a cross-section which is round, elliptical, square, triangular, rectangular or hexagonal.
