Abstract
A dog bone includes a rigid dog bone simulating vessel having in at least one end of the vessel a cavity for receiving therein flavoured compressible dog food.
The cavity extends a first distance into the vessel, so as to extend between an opening aperture at the end of the vessel and a vertex of the cavity spaced the first distance into the vessel. The cavity, when viewed in cross-section, diverges in its lateral dimension between the vertex and the opening aperture so that, at the vertex, the cavity is narrowest and opens radially outwardly relative to a longitudinal axis of the vessel. The flavoured compressible dog food is inserted or insertable into the cavity so as to be compressed against the vertex of the cavity and thereby retained therein. The compressible dog food, which may in one embodiment be in pellet form, is formed of ingredients at least one of which has an attractive taste for a dog and another of which absorb moisture so as to expand when moistened. Such expansion increases the frictional engagement of the dog food compressed into the cavity against the vertex.

Description
DOG BONE
Field of the Invention This invention relates to chewable flavoured novelties for dogs and, in particular, to chewable simulated dog bones adapted to receive replenishable food inserts.
Background of the Invention In the prior art, applicant is aware of United States Patent Number 4,557,219 which issued to Edwards on December 10, 1995 for a Chewable Toy for Animal. Edwards discloses an elastomeric chewable polyurethane toy shaped to simulate a dog bone. The dog bone is chemically inert and includes surface-migrating flavouring mixed with the polyurethane composition. The flavouring is pleasing to the animal. Chewing of the toy releases the flavouring and as the flavouring is dissipated it is continuously replenished from the polyurethane.
Applicant is also aware of United States Patent No. 4,674,444 which issued June 23, 1987 to Axelrod for a Chewing Toy for Dogs and Preparation Thereof.
Axelrod discloses a nylon shaped bone having an impregnated layer of caramelized sugar adjacent and below its

The dog bone is chemically inert and includes surface-migrating flavouring mixed with the polyurethane composition. The flavouring is pleasing to the animal. Chewing of the toy releases the flavouring and as the flavouring is dissipated it is continuously replenished from the polyurethane.
Applicant is also aware of United States Patent No. 4,674,444 which issued June 23, 1987 to Axelrod for a Chewing Toy for Dogs and Preparation Thereof.
Axelrod discloses a nylon shaped bone having an impregnated layer of caramelized sugar adjacent and below its
2 0 surface to impart a flavour to the near-surface of the toy. Axelrod also discloses treating the toy with a second appeal-enhancing agent, such as a ham scent and flavour.
Applicant is further aware of United States Patent No. 3,871,334 which issued to Axelrod on March 18, 1975 for a Pet Toy.
In this earlier patent, Axelrod discloses thoroughly impregnating flavour and odour components into a nylon substrate of a chewing toy by pressure cooking the toy in aqueous meat and animal 2 5 by-products. The resulting chewing toy is permanently impregnated with meat flavour and odour components attractive to animals.
What is neither taught nor suggested is the insertion of replenishable soft food pellets into open end cavities of a simulated dog bone wherein they are retained by friction and expansion due to moisture as an animal such as a dog tries to extract the food from the interior of the cavities.
Summary of the Invention In summary, the dog bone of the present invention includes a rigid dog bone simulating vessel having in at least one end of the vessel a cavity for receiving therein flavoured compressible dog food. The cavity extends a first distance into the vessel, so as to extend between an opening aperture at the end of the vessel and a vertex of the cavity spaced the first distance into the vessel. The cavity, when viewed in cross-section, diverges in its lateral dimension between the vertex and the opening aperture so that, at the vertex, the cavity is narrowest and opens radially outwardly relative to a longitudinal axis of the vessel. The flavoured compressible dog food is inserted or insertable into the cavity so as to be compressed against the vertex of the cavity and thereby retained therein. The compressible dog food, which may in one embodiment be in pellet form, is formed of ingredients at least one of which has an attractive taste for a dog and another of which absorb moisture so as to expand when moistened. Such expansion increases the frictional engagement of the dog food compressed into the cavity against the vertex.
In one preferred embodiment, the vessel is elongate an has two opposite ends, each end having a cavity therein. Advantageously, the vertex of each of the cavities lies on the longitudinal axis of the vessel, and in one embodiment, the longitudinal axis is an axis of symmetry of the vessel and of each cavity.
In the preferred embodiment, the vessel is hourglass-shaped or otherwise shaped in the form of a dog bone.
In order to improve the frictional engagement of the compressible dog food into the cavity, the interior walls of the cavity may be roughened.
Brief Descr~tion of the Drawings Figure 1 is, in perspective view, the dog bone of the present invention.
Figure 2 is a cross sectional view along line 2-2 in Figure 1, being a planar sectional view along longitudinal axis of symmetry A-A.
Figure 3 is the view of Figure 2 showing the insertion of compressible dog food into one cavity.
Detailed Description of the Preferred Embodiment As seen in Figures l and 2, the simulated dog bone 10 of the present invention may, without intending to be limiting, be an elongate generally hourglass-shaped solid chewing toy advantageously simulating the shape of a dog bone. An outer surface 12, which may be smooth, extends between opposite ends 14 which in the preferred embodiment are symmetrically identical.
2 0 Each end 14 has a rim 16 which may be radially symmetric about longitudinal axis A-A. Rims 16 define apertures 18 in ends 14. Apertures 18 are the end-most openings into interior cavities 20. Interior cavities 20 have interior walls 22 which, in one preferred embodiment which is not intended to be limiting, form parabolic or elliptical bodies of revolution about longitudinal axis A-A. Interior cavities 20 may also be conical or frustro-conical so long as a receiving cavity is 2 5 defined deeply into at least one end of dog bone 10, and diverges from a vertex of the cavity towards the opening aperture.

Figure 3 is the view of Figure 2 showing the insertion of compressible dog food into one cavity.
Detailed Description of the Preferred Embodiment As seen in Figures l and 2, the simulated dog bone 10 of the present invention may, without intending to be limiting, be an elongate generally hourglass-shaped solid chewing toy advantageously simulating the shape of a dog bone. An outer surface 12, which may be smooth, extends between opposite ends 14 which in the preferred embodiment are symmetrically identical.
2 0 Each end 14 has a rim 16 which may be radially symmetric about longitudinal axis A-A. Rims 16 define apertures 18 in ends 14. Apertures 18 are the end-most openings into interior cavities 20. Interior cavities 20 have interior walls 22 which, in one preferred embodiment which is not intended to be limiting, form parabolic or elliptical bodies of revolution about longitudinal axis A-A. Interior cavities 20 may also be conical or frustro-conical so long as a receiving cavity is 2 5 defined deeply into at least one end of dog bone 10, and diverges from a vertex of the cavity towards the opening aperture.
3 Typically, dog bone 10 is made of a rigid chew resistant material such as nylon or at least ultra high molecular weight polyethylene. Thus as seen in the cross-sectional views, the intermediate waist of dog bone 10 may be solid, extending between the opposed vertices 24 and side walls of interior cavities 20.
In one preferred embodiment, interior walls 22 have a roughened texture, for example an EDM texture formed thereon as for example during the manufacturing moulding process. A roughened surface of interior walls 22 provides for increased frictional resistance when food 26 is compressed into interior cavities 20 against vertices 24.
In the preferred embodiment, as seen in Figure 3, soft replenishable food supplies such as, for example in the form of compressible pellets 28, are manually inserted in direction B
into interior cavities 20 and manually compressed therein to form a void-free compaction of dog food 26. Depending on the volumetric size of pellets 28 and the number of those pellets employed, the volume of food 26 compacted into the interior ends of interior cavities 20 against vertices 24 will vary. The object is to provide a compressible, flavourful, edible insert into the cavities which will occupy a dog or other animal trying to extract food 26 from within cavities 20.
2 0 Thus, advantageously, pellets 28 have an attractive flavour such as beef liver added to the food mix combined with animal food filler, such as would be known to one skilled in the art. The food tiller expands with the introduction of moisture. Pellets 28 either with the aid of a small amount of water to soften them or in their dry compressible form, are compressed against vertices 24 so as to be firmly wedged between interior walls 22. This will leave an exposed food 2 5 surface 30. An animal such as a dog trying to get at food 26 will typically insert its tongue on aperture 18 into cavity 20 so as to engage food surface 30. The animal will attempt then to lick the food 26 so as to remove it from cavity 20. The licking adds moisture to food 26 causing expansion to food 26 against interior walls 22. Thus as the animal tries to remove the food, the

into interior cavities 20 and manually compressed therein to form a void-free compaction of dog food 26. Depending on the volumetric size of pellets 28 and the number of those pellets employed, the volume of food 26 compacted into the interior ends of interior cavities 20 against vertices 24 will vary. The object is to provide a compressible, flavourful, edible insert into the cavities which will occupy a dog or other animal trying to extract food 26 from within cavities 20.
2 0 Thus, advantageously, pellets 28 have an attractive flavour such as beef liver added to the food mix combined with animal food filler, such as would be known to one skilled in the art. The food tiller expands with the introduction of moisture. Pellets 28 either with the aid of a small amount of water to soften them or in their dry compressible form, are compressed against vertices 24 so as to be firmly wedged between interior walls 22. This will leave an exposed food 2 5 surface 30. An animal such as a dog trying to get at food 26 will typically insert its tongue on aperture 18 into cavity 20 so as to engage food surface 30. The animal will attempt then to lick the food 26 so as to remove it from cavity 20. The licking adds moisture to food 26 causing expansion to food 26 against interior walls 22. Thus as the animal tries to remove the food, the
4 food becomes more firmly wedged within the cavity, thereby resisting its easy removal. The roughened surface of interior walls 22 adds to the ability of food 26 to frictionally resist removal.
In this fashion, an animal such as a dog will be fully occupied for some time while it extracts food 26 by licking it from the interior of cavities 20.
It has been applicant's experience that, in this fashion, food 26 is retained for a significant period of time within cavities 20 even though cavities 20 open or diverge outwardly, for example, in the manner of a cone or pyramid shape, outwardly from vertices 24 along axis A-A. The use of interior cavities 20 having parabolic, elliptical, conical or otherwise diverging cross-sectional shapes (when viewed along axis A-A) is advantageous in that it allows ease of cleaning of the cavities in between replenishment of food 26.
The size of dog bone 10 and the commensurate size of cavities 20 depends on the size of a typical dog which will be given dog bone 10. Thus, for example, large dogs such as Golden Retrievers, Labrador Retrievers, German Shepherds or the like will require larger dog bones accommodating larger cavities. This will allow the dog to insert its tongue in an attempt to retrieve food 26. In that instance, a dog bone might approximate between 15 and 20 cm in length and have a maximum diameter of between 6 and 8 cm, thereby accommodating a cavity having an opening approximately at least 4 cm across and a cavity approximating at least 5 or 6 2 0 cm deep. Smaller dogs with smaller tongues would require proportionally smaller dog bones and corresponding cavities. These dimensions are not intended to be limiting. The cavities do, however, have to be significantly deep to accommodate holding food compacted into their innermost ends. As used herein, the term "significantly deep" is to be considered relative to the typical length of protrusion of a dog's tongue extending into the cavity while the dog is trying to 2 5 lick out the food.
As will be apparent to those skilled in the art in the light of the foregoing disclosure, many alterations and modifications are possible in the practice of this invention
