Pet toy

Abstract

The pet toy has a unique configuration that can dispense pet food from its body. The body has a bore extending radially through the body and in communication with the central cavity. When the pet food is disposed within the cavity, the syringe-type plunger can be used to expel the pet food out of the cavity through the aperture. Furthermore, the pet toy can also have two enlarged end members having different diameters that cause the pet toy to move in a curved trajectory when the pet toy is rotated about its longitudinal axis.

Description

Technical Field

[0001] The present disclosure relates to pet toys. Background Art

[0002] Pet toys offer advantages for pet health. For example, they can aid in dental health, physical exercise, and mental stimulation. Pet toys can come in many different shapes, sizes, and materials. For dogs, some exemplary pet toys are chew toys in the shape of a common dumbbell or barbell. The shape of the dumbbell or barbell dog toys serves as an effective dental aid. When dogs chew and play with these toys, the barbell design massages their gums and helps clean their teeth. The textured surface promotes oral hygiene, reduces plaque buildup, and supports overall dental health.

[0003] The toy's shape allows the dog to grasp and manipulate it, promoting active movement and muscle engagement. This is beneficial because encouraging dogs to play with toys contributes to their physical health. Regular exercise is necessary to maintain a healthy weight, muscle tone, and cardiovascular health.

[0004] Additionally, dogs benefit from mental stimulation as much as physical exercise. Toys engage the dog's mind, prevent boredom, and provide an outlet for natural instincts. Dogs are able to explore different angles and textures, keeping their brains active and entertained.

[0005] Some pet toys incorporate treats for dogs. This further enhances the dog's desire to interact with the toy. However, when a treat is delivered to a pet toy, the treat is dispensed regardless of where the dog is playing with the toy. This can lead to messes. For example, if the treat is peanut butter and the pet toy delivers peanut butter to the dog, the peanut butter can unintentionally make a mess on the carpet where the dog is playing. SUMMARY OF THE INVENTION

[0006] Despite the numerous pet toys currently available, there is still room for improvement. Delivering treats to dogs can be challenging when the treats are stored within the toy's internal volume or compartment and the pet owner wants to ensure the pet toy remains on an easily cleanable surface (e.g., a tile floor rather than carpet). Therefore, there is a need for improved structures for delivering treats to pets, such as dogs, via pet toys that effectively prevent the toy from rolling onto undesirable surfaces. The present invention addresses these issues by providing an improved pet toy that delivers treats while also encouraging the pet toy to remain in a preferred location.

[0046] Like reference numerals refer to like parts throughout the drawings. Details

[0047] The accompanying drawings depict various embodiments of pet toys. Figures 1 to 9 A first embodiment of the pet toy 10 is described. Figures 9 to 18 A second embodiment of a pet toy 110 is described. Figures 19 to 27 A third embodiment of a pet toy 210 is described. Figures 28 to 30 A fourth embodiment of a pet toy 310 is described. Any of these embodiments can be used in combination with the plunger 250 to define a pet toy system or combination for expressing or expelling a pet treat from a pet toy.

[0048] Due to the similarities between the various embodiments, reference numerals are repeated throughout the figures to indicate similar components. Those reference numerals may be described with respect to another embodiment, but for the sake of brevity, may not be repeated in the description of that embodiment. However, it should be understood that components from one embodiment may be present or claimed in another embodiment.

[0049] Figures 1 to 9The pet toy 10 is described as including a body 12. The body 12 can be generally shaped as a dumbbell or barbell having enlarged ends and an elongated center portion extending between the enlarged ends. Although this particular embodiment is generally dumbbell or barbell shaped, other shapes are also possible as described herein.

[0050] The body 12 of the pet toy 10 can be a single unitary body that is integrally extruded, molded, printed, or additively manufactured, removably machined, or formed into a single, integral component that is substantially made of flexible, semi-flexible, or semi-rigid, artificial or natural materials. The body 12 of the pet toy 10 can be formed of an elastic or rubber material configured to withstand deformation when the pet (i.e., dog) bites or bends. In one embodiment, polymers such as silicone, plastic (polypropylene or PVC), or rubber can form most of the parts or elements used to manufacture the body of the pet toy and various parts that are integrally formed, molded, or extruded therewith. Silicone is a polymerized siloxane compound composed of chains of alternating silicon (Si) and oxygen (O) atoms. While most industrial polymers contain carbon in their main chains, silicone is a unique "inorganic" polymer. Silicone is known for its chemical inertness, water and oxidation resistance, stability at extreme temperatures, flexibility, and heat resistance. Plastics are polymeric materials with different properties. Due to its plasticity, they can be molded or shaped, which combines low density, low conductivity, transparency and toughness. Some exemplary commercial resins include high-volume, low-cost plastics such as polyethylene, polypropylene, polyvinyl chloride (PVC) and polystyrene. Natural rubber, also known as latex, is composed of a polymer of the organic compound isoprene (C5H8). It contains a small amount of impurities of other organic compounds. Natural rubber is stretchable, elastic and waterproof. The pet toy body should withstand the typical biting or chewing forces imparted by a dog, who interacts with the pet toy with his or her mouth.

[0051] While it is contemplated that the body 12 of the pet toy 10 and its associated components described herein are uniformly and integrally extruded, molded, or formed, as will be appreciated by those skilled in the art, the components of the pet toy body may be formed separately from other materials. Furthermore, while the components of the body 12 of the pet toy 10 are discussed individually below, it should be clearly understood that the components of the pet toy body and their corresponding reference elements are portions, regions, or surfaces of the body 12 and each form a separate element or component of a single pet toy body. Thus, while these components may be discussed and identified separately from other elements or components of the body 12 of the pet toy 10, in this exemplary embodiment, there is a single pet toy body 12 having the portions, regions, or surfaces described below.

[0052] The body 12 of the pet toy 10 extends along a central longitudinal axis 18 between a first end 14 and a second end 16. A first expansion member 20 defines the first end 14 of the body 12. A second expansion member 22 defines the second end 16 of the body 12. An elongated central portion 24 of the body 12 extends between the first expansion member 20 and the second expansion member 22. The elongated central portion 24 defines a cavity 26 therein. At least one opening or aperture is defined in the body. The at least one opening is in open communication with the cavity, and the opening allows a treat stored in the cavity to exit the body 12. In one embodiment, the opening is formed in one of the expansion members 20 or 22. In another embodiment, one opening is formed in each of the expansion members 20 and 22. In other embodiments, the opening or aperture extends radially through the elongated central portion 24 of the body 12.

[0053] The first expansion member 20 has a first dimension 28. The first dimension 28 extends through the central longitudinal axis 18 and is measured between two different points on the circumference of the first expansion member 20. In one embodiment, when the first expansion member 20 has a circular profile, the first dimension 28 is a diameter. However, if the first expansion member 20 has a profile shape other than a circular profile, the dimension 28 may not be a "diameter."

[0054] The second expansion member 22 has a second dimension 30. The second dimension 30 extends through the central longitudinal axis 18 and is measured between two different points on the circumference of the second expansion member 22. In one embodiment, when the second expansion member 22 has a circular profile, the second dimension 30 is a diameter. However, if the second expansion member 22 has a profile shape other than a circular profile, this dimension may not be a "diameter."

[0055] In a particular embodiment, the first dimension 28 is greater than the second dimension 30. An advantage of having the first dimension 28 be different from or greater than the second dimension 30 is that it causes the pet toy 10 to roll in a circular motion (e.g., along a curved path) when the pet toy is rotated about the longitudinal axis 18. This allows the pet toy 10 to remain within the general area defined by the rolling path. This is advantageous for pet owners because, during use / play, the pet toy 10 does not roll away to another area of ​​the home where the pet owner does not want the pet to have access to the toy. For example, the pet toy 10 will roll in a circular motion on a tile floor and will not inadvertently roll onto a carpeted area.

[0056] More specifically, when two expanding members 20 and 22 of different diameters are connected by an elongated central portion 24 that acts as an axis, the pet toy 10 exhibits a unique rolling behavior. Specifically, as one expanding member rolls, points along its circumference trace a specific path. This path is known as a cycloid. Due to their different diameters, the two expanding members exhibit different cycloid curves. These different cycloid curves cause the pet toy to roll along a curved path in a circular motion (when viewed from above). Specifically, when the pet toy 10 rolls, the larger expanding member (i.e., the first expanding member 20) travels a longer distance (circumference) in a single rotation than the smaller expanding member (i.e., the second expanding member 22). Because the first and second expanding members 20 and 22 are connected by the elongated central portion 24, they rotate together. However, due to their different diameters or circumferences, the expanding members 20 and 22 experience different angular displacements during each rotation. The larger expanding member (i.e., the first expanding member 20) covers a larger angle (i.e., a larger arc) than the smaller expanding member (i.e., the second expanding member 22). This difference in relative motion causes the pet toy 10 to deviate from its straight path as it rolls and rotates about the axis 18. The combined effect of the different angular displacements results in a curved path 40 for the pet toy 10 as it rolls. The pet toy 10 tends to rotate toward the side with the smaller enlarged member (i.e., the second enlarged member 22).

[0057] The different sizes of the first and second expansion members 20 and 30 can determine the ratio of the first dimension 28 to the second dimension 30. In one embodiment, the ratio of the first dimension 28 to the second dimension 30 is at least 1.05:1. In another embodiment, the ratio of the first dimension 28 to the second dimension 30 is in the range of about 1.05:1 to about 4:1. These dimensions and ratios are not merely a matter of design choice. Rather, it has been determined that embodiments utilizing this ratio can optimize the rolling of the pet toy 10 along a curved path or trajectory 40, allowing for sufficient rolling to stimulate the dog while still adequately maintaining or retaining the pet toy 10 in a desired area during use by the pet. In one specific embodiment, the ratio of the first dimension 28 to the second dimension 30 is 41:32. When the ratio is 41:32, the first dimension 28 is 82 units (i.e., millimeters) and the second dimension is 64 units (i.e., millimeters). These units illustrate that one embodiment has a first dimension 28 to second dimension 30 ratio of approximately 4:3 (i.e., 1.33:1).

[0058] Although the curved path 40 is imparted based on different dimensions 28 and 30, an oscillatory motion can also be introduced into the curved path 40. This is achieved by giving one of the enlarging members an elliptical profile, so that it acts as a cam while the other enlarging member is circular. In this example, the second enlarging member 22 has an elliptical (oval) profile and a smaller diameter dimension 30. The first enlarging member 28 has a larger circular profile. When the pet toy 10 moves forward, the larger circular enlarging member 20 covers more ground per rotation than the smaller elliptical member 22. Centripetal acceleration acts on the centers of rotation of members 20 and 22. However, due to the different circumferences, the smaller elliptical member 22 experiences a shorter centripetal acceleration than the larger circular member 20. The combination of these effects results in a curved path for the entire pet toy 10. Furthermore, the elliptical shape of the second enlarging member 22 introduces oscillation during the curved motion. When the pet toy 10 rolls, the smaller elliptical member 22 experiences varying centripetal acceleration, causing it to oscillate slightly, creating an undulating motion superimposed on the curved path 40. The motion of the pet toy 10 tends to turn toward the side with the smaller oval member 22, resulting in a curved trajectory 40 and a pet-stimulating interaction of oscillation. Alternatively, the enlarged members 20 and 22 can have an oval profile to produce oscillation during the rolling of the pet toy 10.

[0059] In the exemplary embodiment shown, the first and second expansion members 20 and 22 are disc-shaped expansion areas having outer surfaces. In one embodiment, the outer surfaces of the first and second expansion members are generally convex, while the inner surfaces are generally concave. Each of the first and second expansion members 20 and 22 also has an outermost edge and an outermost surface. The first expansion member 20 can define an opening 32 that is in open communication with the cavity 26 of the elongated central portion 24. This exemplary opening is free of any protrusions or other obstructions and is simply generally circular in shape.

[0060] The second expansion member 22 can also define an opening 34 that is openly connected to the inner cavity 26. The edge defining the opening 34 can have any geometric shape. In a specific example, the edge can include multiple connecting portions that define a star-shaped opening. The star-shaped opening can be defined by a generally circular peripheral edge that is periodically interrupted by multiple protrusions extending inward toward the longitudinal axis. The star-shaped opening is shown as including six protrusions. However, it is entirely conceivable that the edge defining the opening 34 can have any shape suitable for passing pet food through it. For example, instead of a star-shaped opening defined by a star-shaped edge, the opening can simply be circular. Alternatively, as shown in other examples herein, the opening 34 can be a simple circle.

[0061] The elongated central portion 24 has a smaller diameter than the expansion members 20 and 22. The elongated central portion 24 extends between the expansion members. The elongated central portion 24 may include a wall configured to include a plurality of ridges 36 extending radially outward from an outer surface of the elongated central portion 24 relative to the axis 18. The ridges 36 are spirally wound or wound around the longitudinal axis 18. In the example shown, the number of ridges 36 on the elongated central portion is between 3 and 9. There may be a gap space 38 between two adjacent ridges 36.

[0062] In one exemplary embodiment, the angular rotation of each ridge can be approximately 180° about the longitudinal axis 18 along the length of the elongated central portion 24. For example, a first end of one of the ridges 36 can begin on a side of the elongated central portion proximate the first dilation member 20. The ridge 36 can spiral approximately 180° about the longitudinal axis 18 along the length of the elongated central portion 24, such that a second end of the ridge 26 terminates on an opposite side of the elongated central portion 22 proximate the second dilation member 22. In other embodiments, the ridges can spiral more than 180° about the longitudinal axis 18 along the length of the elongated central portion 24. For example, the ridges 36 can spiral approximately 270°, 360°, 450°, 540°, 630°, 720°, 810°, 900°, 990°, 1080°, or more about the longitudinal axis 18 along the length of the elongated central portion 24.

[0063] In the first embodiment, the elongated central portion 24 is cylindrical. Between the first and second enlarging members 20, 22, the outer wall of the elongated central portion 24 is oriented parallel to and concentric with the longitudinal axis 18 along its entire length.

[0064] Figures 10 to 18 A second embodiment of a pet toy 110 is described. As previously described, components of the pet toy 110 having similar reference numerals as the pet toy 10 are identical. As can be seen, the pet toy 110 is similar to the pet toy 10, except that the elongated center portion 124 tapers from a first end to a second end.

[0065] In the second embodiment of the pet toy 110, the elongated central portion 124 is shaped as a tapered cylinder. A tapered cylinder is a three-dimensional shape known as an inverted truncated cone. It is formed when the apex of the cone is cut by a plane parallel to the base of the shape and the cone is inverted. Thus, the tapered cylinder has a tapered profile from one end to the other. In the illustrated embodiment, the profile of the elongated central portion 124 tapers from the first enlarging member 20 to the second enlarging member 22. Enlarging members 20 and 22 still have different sizes to facilitate the curved rolling path or curved track 40 as previously described.

[0066] The angle at which the elongated central portion 124 tapers from the first end to the second end can vary depending on the specific application needs of the pet toy 110. For example, a larger taper angle may be desirable for a pet toy 110 intended for use with smaller dogs. Larger dogs, on the other hand, may prefer a pet toy 110 with a smaller taper angle. In one embodiment, the elongated central portion 124 may taper approximately 25% of its longitudinal length. In other words, if the diameter of the elongated central portion 124 near the first expansion member 20 is equal to X, the diameter of the elongated central portion 124 near the second expansion member 22 may be equal to approximately 75% of X. Thus, if the elongated central portion 124 has an outer diameter of 4 units near the first expansion member 20, the elongated central portion 124 will have an outer diameter of 3 units near the second expansion member 22.

[0067] Figures 19 to 27 It is depicted that the pet toy 210 can include one or more slots or apertures 242 that extend completely through the body 12 at the elongated central portion 224. The elongated central portion 224 of the pet toy 210 can be a tapered cylindrical shape (e.g., similar to the pet toy 110) or a right cylindrical shape (e.g., similar to the pet toy 10).

[0068] The holes 242 extend radially relative to the axis 18. The holes 242 can define a plurality of holes that are openly connected to the interior central cavity 26 of the elongated central portion 224. The holes 242 can extend in a spiral or helical manner within the interstitial spaces 38 between adjacent ridges 36. In the illustrated embodiment, the holes 242 are located in each space 38 between adjacent ridges 36, however, the holes 242 can also be located only in certain spaces 38 between adjacent ridges 36. Furthermore, while the holes 242 follow a spiral or helical pattern, this is not required. Furthermore, the holes 242 can all have a uniform diameter, or some of the holes 242 can have diameters that differ from one another.

[0069] like Figure 26 As shown, the hole 242 extends completely through the central portion 224 from the inner surface 244 to the outer surface 246 thereof. The inner surface 244 defines the central cavity 26. The inner surface 244 can have a substantially uniform diameter along the length of the cavity 26, regardless of whether the outer surface of the central portion 224 is straight or tapered.

[0070] Near the second end of the cavity 26, the inner surface 244 may include a tapered wall 248. The tapered wall terminates at an edge that defines the circular opening 34 in the second enlarging member 22. The tapered wall tapers at an angle complementary to the end of the plunger, as will be discussed below.

[0071] Continue to refer Figure 26 and Figure 27 , the interior central cavity 26 is configured to receive a pet treat therein. The pet toy 210 (or other embodiments of the pet toy) can be used in conjunction with a syringe-type plunger 250. The plunger has a distal end 252 shaped to have a tapered surface that complements or matches the angle or orientation of the tapered wall 248 in the elongated central portion 224. In addition, the diameter of the distal end 252 of the plunger complements or matches the inner diameter of the inner surface 244 of the elongated central portion 224.

[0072] In one embodiment, the distal end 252 of the plunger 250 is where the plunger contacts the material (e.g., pet treat or medication) within a hole or cavity (e.g., cavity 26). The distal end 252 of the plunger 250 generally has a generally conical shape. This tapered surface serves several purposes. When the plunger 250 is pushed into the hole or cavity 26, the tapered tip of the distal end 252 forms a tight seal against the inner wall or surface 244 defining the cavity 26. The tapered surface of the distal end 252 helps the material move through the cavity 26 as the plunger 250 is pushed. The tapered shape also minimizes dead space to ensure that the maximum amount of material can be discharged or ejected from the pet toy.

[0073] In operation, the user loads the pet treat into the central cavity 26 of the pet toy. Typically, this occurs by inserting the pet treat through the opening 32 formed in the first expansion member 20. The user can then axially align the length of the plunger 250 along the shaft 18, as shown in FIG. Figure 27 . In this orientation, the distal end 252 of the plunger 250 is closer to the pet toy 210 than the proximal end of the plunger 250. Thus, the plunger moves closer to the first end of the pet toy 210. The plunger 250 continues to move toward the pet toy 210 until the distal end is inserted through the opening 32 in the first expansion member 20. The diameter of the distal end 252 can also be equal to or complementary to the diameter of the opening 32. This allows the plunger to be inserted through the opening 32. The user continues to apply force to the proximal end of the plunger 250 along the shaft 18.

[0074] With the distal end 252 of the plunger 250 now within the central cavity 26, the user will continue to apply force along the shaft 18 to push the plunger 18 further into the cavity 26. Recall that the pet treat was already inserted into the central cavity 26 before the plunger 250 was inserted into the cavity. Therefore, as the user pushes the plunger 250 deeper into the cavity 26, the pet treat will be expelled, ejected, and dispensed through the aperture 242. This expulsion or dispensing of the treat deposits the treat on the outer surface 246 of the elongated central portion 224. The pet can then grasp or eat the treat that has been deposited on the outer surface 246 of the elongated central portion 224.

[0075] Owing to using plunger to distribute food, preferably, food is semisolid or viscous material to realize distribution, rather than hard, solid or non-viscous material.In a specific embodiment, the preferred food used together with the pet toy of the present disclosure and plunger 250 is peanut butter. Peanut butter is preferred because it is a non-Newtonian fluid and shows shear thinning behavior. However, other more viscous Newtonian fluids or non-Newtonian fluids (e.g., gel) are also completely possible. For example, this assembly can be used together with yogurt, cheese, cream, oatmeal or other more viscous harmless and / or pet-friendly food. This can also be used for distributing medicine to pet when medicine is integrated into food. For example, medicine for dog can be dipped into food so that dog consumes medicine in response to licking or eating this food.

[0076] In a specific example, when the treat is peanut butter, as the plunger moves axially along shaft 18, it generates shear forces within the peanut butter. These shear forces cause the peanut butter to behave as a non-Newtonian fluid—its viscosity changes under stress. The increased pressure from plunger 250 forces the peanut butter to flow. Due to radial holes 242, the peanut butter begins to move outward from central hole or cavity 26. Holes 242 serve as channels, allowing the peanut butter to escape. As plunger 250 continues to push, the peanut butter flows through these holes 242. In one exemplary embodiment, as the shear forces increase (due to the movement of plunger 250 along shaft 18), the peanut butter becomes less sticky. This allows the peanut butter to flow more easily through holes 242. As the peanut butter is pushed out of holes 242, the consistency of the peanut butter changes from firm to less firm. This combination of a pet toy, plunger 250, and peanut butter can be used to dispense peanut butter in a controlled manner. By adjusting the plunger force along shaft 18, the user (i.e., the pet owner) can control the rate at which the peanut butter flows through holes 242.

[0077] To estimate the force required to expel peanut butter from a pet toy, pet toy manufacturers should consider the shear stress required to push the peanut butter through hole 242. The shear stress depends on factors such as the diameter of hole 242, the viscosity of the peanut butter, and the pressure. The amount of force a user should apply to plunger 250 will depend on the diameter of hole 242 (e.g., smaller holes require more force due to increased shear stress), the consistency of the peanut butter (e.g., more hydrated peanut butter flows more easily), and the plunger design (e.g., the shape, diameter, and / or surface area of ​​the plunger's distal end).

[0078] It has been determined that certain advantageous configurations of pet toys can take into account the diameter of the hole 242 relative to the inner diameter of the central cavity (i.e., measured between two points on the inner surface perpendicular to the shaft 18). In one exemplary embodiment, the hole 242 can have a diameter of about 3 mm to about 9 mm. In a specific embodiment, the hole 242 has a diameter of about 5 mm.

[0079] In an exemplary embodiment, the inner diameter of cavity 26 can be between about 22 mm and about 32 mm as measured through inner surface 244. In a specific embodiment, the inner diameter of cavity 26 is about 27 mm (about 1 inch).

[0080] The ratio of the inner diameter of cavity 26 to the diameter of the aperture (e.g., aperture 242 or other apertures shown herein) can be about 3:1 to about 7:1. In a particular embodiment, the ratio of the inner diameter of cavity 26 to the diameter of the aperture (e.g., aperture 242 or other apertures shown herein) is about 5:1 (e.g., about 27:5). These ratios have been found to be beneficial in balancing the amount of force required to expel peanut butter from the pet treat without sacrificing the functional seal provided by the aperture when the plunger is not inserted into the pet toy, thereby preventing the peanut butter from inadvertently leaking.

[0081] The distal end 252 of the plunger 250 is sized to match the central cavity 26 to facilitate cleaning of the inner surface 244 as the gourmet food is dispensed. Much like the plunger effectively cleans the barrel of a syringe as the gourmet food is dispensed, the distal end 252 of the plunger 250 moves along the inner surface in a close sliding frictional engagement to effectively scrape the inner surface 244, leaving a clean surface after the distal end 252 of the plunger has passed.

[0082] The distal end 252 of the plunger 250 continues to be pressed toward the second end of the pet toy 210 toward the second expansion member 22 until the tapered wall on the distal end 252 meets the tapered wall 248 on the inner surface 244. When the tapered wall on the distal end 252 meets the tapered wall 248 on the inner surface 244, the remaining goodies are expelled or dispensed from the opening 34 in the second expansion member 22.

[0083] Figures 28 to 30 It is depicted that the pet toy 310 can include one or more slots or apertures 342 that extend completely through the body 12 at the elongated central portion 324. The elongated central portion 324 of the pet toy 310 can be a tapered cylindrical shape (e.g., similar to the pet toy 110) or a right cylindrical shape (e.g., similar to the pet toy 10).

[0084] The bore 342 extends radially relative to the shaft 18. The bore 342 can define a plurality of holes that are in open communication with the interior central cavity 26 of the elongated central portion 324. This embodiment differs in that the ridges 336 extend linearly (i.e., not helical) between the first and second expansion members 20, 22. The interstitial space 338 also extends linearly.

[0085] The holes 342 may extend in a linear pattern within the interstitial spaces 338 between adjacent ridges 336. In the illustrated embodiment, the holes 342 are located only in some of the spaces 338 between adjacent ridges 336. In this embodiment, the holes 342 are formed only in some of the spaces 338 for ease of manufacturing. Specifically, if the pet toy 310 were a molded product, forming a mold with many holes 342 would be difficult or costly to produce. Therefore, the pet toy 310 provides a suitable alternative, wherein the holes 342 are suitable for expelling pet treats from a central cavity in the manner of the plunger 250 described above, but also reduces manufacturing costs.

[0086] Specifically, the illustrated example of the pet toy 310 depicts holes 342 only on two sides of the elongated center portion 324. This is beneficial when the pet toy 310 is molded from two molds connected at a parting line. The holes 342 on each side of the pet toy 310 can have the same diameter or different diameters. Figures 28 to 30 The specific configuration shown depicts a first set of holes 342A formed on a first side of the elongated center portion 324 having a larger diameter than a second set of holes 342B on a second side of the elongated center portion 324. In certain exemplary embodiments, the set of holes 342A may have a diameter of approximately 3 mm to approximately 9 mm. In one embodiment, the set of holes 342A has a diameter of approximately 5 mm. In certain exemplary embodiments, the set of holes 342B may have a diameter of approximately 1 mm to approximately 4 mm. In one embodiment, the set of holes 342B has a diameter of approximately 2 mm. In another embodiment, the ratio of the diameter of the set of holes 342A to the diameter of the set of holes 342B is 5:2.

[0087] This technology for dispensing treats from a pet toy does not need to be used with the barbell-shaped toys discussed above. The plunger 250 can be used to dispense treats from a pet toy, regardless of its external configuration. For example, the pet toy can have the external shape of an inanimate object, such as a fire hydrant, a dog bone, a ball, or any other shape that attracts and / or stimulates a dog. Alternatively, the pet toy can have an external shape that is a symbol of an organism from any classification domain or realm. For example, the pet toy can generally resemble a fish, an animal, or a reptile. Each of these exemplary pet toys can have a hole 34 formed through the side wall of the body, particularly at an elongated central portion defining a central cavity similar to cavity 26, which is configured to discharge or dispense the pet treats when pushed / discharged with the plunger 250.

[0088] Unless it is explicitly stated that a specific shape or structure of a component is mandatory, any element, component or structure discussed herein may take the form of any shape. Therefore, although the drawings depict various elements, components or structures of the present disclosure according to one or more exemplary embodiments, it should be understood that any other geometric configuration of the element, component or structure is entirely possible. For example, instead of the apertures 242 or 342 being circular, the apertures 242 or 342 can be semicircular, triangular, rectangular or square, a pentagon, hexagon, heptagon, octagon, decagon, dodecagon, rhombus or other parallelogram, trapezoid, star, ellipse, oval, line or line-like, teardrop, cross, ring, heart, arrow, crescent, any letter shape (i.e., A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y or Z), or any other type of regular or irregular, symmetrical or asymmetrical configuration.

[0089] Various inventive concepts can be embodied as one or more methods, of which one example is provided. The actions performed as part of the method can be ordered in any suitable manner. Thus, embodiments can be constructed in which actions are performed in an order different from that shown, which can include performing certain actions simultaneously, even though shown as sequential actions in an illustrative embodiment.

[0090] Although various inventive embodiments have been described and illustrated herein, a person of ordinary skill in the art will readily conceive of various other devices and / or structures for performing the functions described herein and / or obtaining the results and / or one or more advantages, and each of these variations and / or modifications is considered to be within the scope of the inventive embodiments described herein. More generally, a person of ordinary skill in the art will readily understand that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary, and that actual parameters, dimensions, materials, and / or configurations will depend on one or more specific applications in which the present invention is used. A person of ordinary skill in the art will recognize or be able to determine many equivalents to the specific inventive embodiments described herein using only routine experimentation. Therefore, it should be understood that the above-described embodiments are given by way of example only, and within the scope of the appended claims and their equivalents, the inventive embodiments may be implemented differently than as specifically described and claimed. The inventive embodiments of the present disclosure relate to each individual feature, system, product, material, kit, and / or method described herein. Furthermore, any combination of two or more such features, systems, articles, materials, kits, and / or methods, provided such features, systems, articles, materials, kits, and / or methods are not mutually inconsistent, is included within the inventive scope of the present disclosure.

[0091] All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and / or ordinary meanings of the defined terms.

[0092] The articles "a" and "an" as used in this specification and claims should be understood to mean "at least one," unless expressly stated otherwise. The phrase "and / or" as used in this specification and claims (if any) should be understood to refer to "one or both" of the elements so combined, i.e., elements that are present in combination in some cases and separately in other cases. Multiple elements listed with "and / or" should be interpreted in the same manner, i.e., "one or more" of the elements so combined. In addition to the elements specifically identified by the "and / or" clause, other elements may optionally be present, whether related or unrelated to those specifically identified elements. Thus, as a non-limiting example, a reference to "A and / or B," when used in conjunction with open language such as "comprising," may refer, in one embodiment, to only A (optionally including elements other than B); in another embodiment, to only B (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); and so on. As used in this specification and claims, "or" should be understood to have the same meaning as "and / or" defined above. For example, when separating items in a list, "or" or "and / or" should be interpreted as inclusive, that is, including at least one, but also including more than one number of elements or lists, and optionally, additional unlisted items. Only when the opposite term is clearly indicated, such as "only one" or "exactly one", or when used in a claim, "consisting of" will mean including exactly one element or one element in a list of elements. Generally, the term "or" as used herein should only be interpreted to indicate exclusive substitution (i.e., "one or the other but not both"), when preceding an exclusive term, such as "either", "one of", "only one of", or "exactly one of". When used in the claims, "consisting essentially of" should have its ordinary meaning used in the field of patent law.

[0093] As used in this specification and claims, the phrase "at least one" with respect to a list of one or more elements should be understood to mean at least one element selected from any one or more elements in the list of elements, but does not necessarily include at least one of each element specifically listed in the list of elements, and does not exclude any combination of elements in the list of elements. This definition also allows for the optional presence of elements in addition to the elements specifically identified within the list of elements to which the phrase "at least one" refers, whether related or unrelated to those specifically identified elements. Thus, as a non-limiting example, "at least one of A and B" (or equivalently, "at least one of A or B," or equivalently, "at least one of A and / or B") can refer to at least one, optionally including more than one A, without B (and optionally including elements other than B), in one embodiment; to at least one, optionally including more than one, B, without A (and optionally including elements other than A), in another embodiment; to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements), in yet another embodiment; etc.

[0094] Although the components of the present disclosure are described herein in relation to one another, if claimed or used separately, any one of the components disclosed herein may comprise the subject matter of the present disclosure. Consistent with the above examples, if a disclosed embodiment teaches features of A and B, then, unless otherwise indicated herein, the subject matter of the present disclosure may be present in the combination of A and B alone, A alone, or B alone.

[0095] As used in this specification and in the claims, the term "enable" or a phrase or claim element beginning with the term "enable" should be understood to mean causing something to occur or bringing about something. For example, an event may be caused to occur by the actions of a first party even if the second party actually performs the event or the second party causes the event to occur. In other words, enabling refers to one party giving another party the tools, objects, or resources to cause the event to occur. Thus, in this example, the claim element "enables the event to occur" would mean that the first party is providing the second party with the tools or resources necessary for the second party to perform the event, whereas the affirmative single action is the first party's responsibility to provide the tools or resources to cause the event to occur.

[0096] When a feature or element is referred to as "on another feature or element" in this article, it can be directly on another feature or element, or there can be intermediate features and / or elements. Conversely, when a feature or element is referred to as "directly" on another feature or element, there are no intermediate features or elements. It should also be understood that when a feature or element is referred to as "connected," "attached" or "coupled" to another feature or element, it can be directly connected, attached or coupled to another feature or element, or there can be intermediate features or elements. Conversely, when a feature or element is referred to as "directly connected," "directly connected" or "directly coupled" to another feature or element, there are no intermediate features or elements. Although described or illustrated with respect to one embodiment, the features and elements described or illustrated in this manner can be applied to other embodiments. Those skilled in the art will also understand that the structure or feature mentioned as being "adjacent" to another feature arrangement can have a portion that overlaps with or is located below an adjacent feature.

[0097] Spatially relative terms, such as "under," "below," "lower," "over," "upper," "above," "behind," "in front of," and the like, may be used herein for ease of description to describe the relationship of one element or feature to another element or feature as shown in the figures. It should be understood that spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation shown in the figures. For example, if the device in the figures were inverted, an element described as "under" or "beneath" would be oriented "over" the other element or feature. Thus, the exemplary term "under" can include both orientations of over and below. The device may be otherwise oriented (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly. Similarly, the terms "upwardly," "downwardly," "vertical," "horizontal," "lateral," "transverse," "longitudinal," etc., are used herein for purposes of explanation only, unless specifically stated otherwise.

[0098] Although the terms "first" and "second" may be used herein to describe various features / elements, these features / elements should not be limited by these terms unless the context indicates otherwise. These terms may be used to distinguish one feature / element from another. Thus, a first feature / element discussed herein could be referred to as a second feature / element, and similarly, a second feature / element discussed herein could be referred to as a first feature / element without departing from the teachings of the present disclosure.

[0099] An embodiment is an implementation or example of the present disclosure. Reference in the specification to "an embodiment," "an embodiment," "certain embodiments," "a specific embodiment," "exemplary embodiments," or "other embodiments" means that the particular features, structures, or characteristics described in conjunction with the embodiment are included in at least some embodiments of the present invention, but not necessarily in all embodiments. The various appearances of "an embodiment," "an embodiment," "certain embodiments," "a specific embodiment," "exemplary embodiments," or "other embodiments" do not necessarily all refer to the same embodiment. Furthermore, the use of any and all examples or exemplary language ("for example," "such as," etc.) is intended merely to better illustrate or describe the embodiments and not to limit the scope of the embodiments or these implementations. No language in this specification should be construed to indicate that any non-claimed element is essential to the implementation of the disclosed embodiments.

[0100] If the specification states that a component, feature, structure, or characteristic "may," "might," or "could" be included, that particular component, feature, structure, or characteristic is not required to be included. If the specification or claims refer to "a" or "an" element, this does not mean there is only one of the element. If the specification or claims refer to "an additional" or "another" element, this does not preclude the presence of more than one of the additional or another element.

[0101] As used in this specification and claims, including those used in the examples, and unless otherwise expressly stated, all numbers can be understood as if prefixed with the word "about" or "approximately", even if the term does not explicitly appear. When describing a quantity and / or position to indicate that the value and / or position described is within a reasonable expected range of value and / or position, the phrase "about" or "approximately" can be used. For example, a numerical value can have a value (or value range) of + / -0.1%, a value (or value range) of + / -1%, a value (or value range) of + / -2%, a value (or value range) of + / -5%, a value (or value range) of + / -10%, etc. Any numerical range described herein is intended to include all subranges contained therein. In addition, unless otherwise stated herein, the description of the range of values ​​herein is not meant to be restrictive, but to individually mention any and all values ​​falling within the range, and each individual value within the range is incorporated into this specification as if it were individually described herein.

[0102] In addition, the method of performing the present disclosure may occur in an order different from that described herein. Therefore, unless explicitly stated otherwise, the sequence of the method should not be understood as limiting. It will be appreciated that similar results can be obtained by performing certain steps of the method in a different order.

[0103] In the claims and the foregoing description, all transitional phrases such as "including," "comprising," "carrying," "having," "containing," "involving," "maintaining," "composed of," etc. should be understood as open-ended, i.e., meaning including but not limited to. Only the transitional phrases "consisting of" and "consisting essentially of" should be closed or semi-closed transitional phrases, respectively.

[0104] To the extent that the present disclosure uses the term "invention" in various headings or sections of this specification, or in the context of such sections, such term has been included pursuant to the formatting requirements for word document submissions (i.e., docx submissions) in accordance with the guidelines / requirements of the United States Patent and Trademark Office, and should not in any way be considered a repudiation of any subject matter.

[0105] In the foregoing description, certain terms have been used for brevity, clarity, and understanding. No unnecessary limitations beyond the requirements of the prior art are intended thereby, as such terms are used for descriptive purposes and are intended to be broadly interpreted.

[0106] Moreover, the descriptions and illustrations of the various embodiments of the disclosure are examples, and the disclosure is not limited to the exact details shown or described.
