The invention relates to a pet toy for dispensing treats, and more particularly, to a pet toy having a rolling dispensing element that is engaged with a peripheral body that remains substantially stationary while the dispensing element rotates to dispense treats.
Due to the increased commercialization of pet products and particularly pet toys, there are now a wide range of pet toys available with many distinct functional features. Pet toys can be made from many different types of materials along with a nearly limitless number of shapes and colors.
One general category of pet toys is those made of a flexible or elastomeric material, such as rubber. These toys, if made from quality materials, can withstand the biting action of an animal, and can keep an animal occupied for extended periods of time. It is known to place treats in these types of toys to increase the interaction of the animal with the toy. A sound emitting device, often referred to as a “squeaker”, is also known to be placed inside the toy to further stimulate the animal.
Another general category of pet toys are those which may generally be referred to as “plush” toys. These types of toys are made from different types of cloth or fabric, and may also include material woven into strands, such as nylon rope. The plush toy is typically stuffed with a fibrous material, such as polyester stuffing, to provide the toy with an increased thickness or bulk that enables the animal to chew on the toy. Plush toys may also include squeakers to further stimulate the animal.
Yet another general category of pet toys are those that are especially adapted for dispensing treats. This category is typically incorporated within a pet toy that has a chamber to receive the treats and one or more openings that enable the treats to be dispensed by movement of the toy.
One example of a treat dispensing pet toy includes the invention disclosed in the U.S. Pat. No. 8,904,967. The treat dispenser dispenses treats by moving the dispenser in a way to gravity release treats from the interior hollow chamber of the toy. The dispenser includes a central spherical body, and a plurality of peripherally spaced spheres or balls connected to the body by respective branches. Each of the balls has a treat dispensing opening. The body has an opening for charging or loading treats. As an animal plays with the device, treats are dispensed through the openings. The openings are located at different positions on each of the balls so that treats are likely to be dispensed when the device is placed at various orientations.
Another example of a treat dispensing toy is disclosed in the U.S. Pat. No. 6,073,581. A ball-like toy includes a spherical shell and a cylindrical valve, the spherical shell being formed of two symmetrical half shells. The half shells have ribs and partition boards, the cylindrical valve being mounted in a hole on the spherical shell and retained between the ribs and partition boards of the half shells. When the toy is rotated within a limited angle, dog food is discharged out of the spherical shell through the cylindrical valve when the spherical shell is rolled on the ground.
Yet another example of a treat dispensing toy is disclosed in the U.S. Pat. No. 7,600,488. This reference provides a pet with a body having a first treat-retaining cavity and a first opening that extends between the first treat-retaining cavity and an outer surface of the body. A metering device in the first opening dispenses treats from the first treat-retaining cavity through the first opening at a metered rate. The first treat-retaining cavity is refillable through the metering device.
Considering the common forms of construction for many types of pet toys, there is still a need to provide a pet toy that can dispense treats in a manner that will provide greater interest to an animal for extended play and interaction with the toy. There is also a need to provide a pet toy that is robust enough to withstand contact by the animal and owner, but is relatively simple in construction and therefore can be produced at a reasonable cost.
The invention described below provides solutions to many limitations in the prior art and incorporates a unique construction which is capable of continuously dispensing treats in a reliable manner. The invention also provides a pet toy that is relatively simple in structure, but provides multiple distinct features which may enhance an animal's interaction with the pet toy.
According to a preferred embodiment of the invention, it includes a pet toy having a peripheral body or peripheral ring and a central or interior rolling dispenser engaged with the peripheral body. The peripheral body has a ring shape with an interior curved engaging surface which engages an exterior spherical surface of the rolling dispenser. The curvature of the interior engaging surface allows the rolling dispenser to continuously roll or rotate, yet maintain engagement with the peripheral body. When placed on a flat surface, the peripheral body remains substantially parallel with the flat surface and thereby provides additional stability to the dispenser so that the dispenser may continuously roll when the pet toy is moved by contact with the peripheral body.
The dispenser is hollow thereby defining a chamber to receive treats. One or more dispensing openings are provided on the dispenser to selectively dispense treats. The one or more openings can be sized to selectively dispense treats of various sizes and shapes.
The dispenser may be configured in two pieces that are engaged by threads. In order to load the dispenser, the pieces are unscrewed, treats are placed in the chamber of the dispenser, and then the pieces are screwed together. Additionally or alternatively, treats may be loaded in the dispenser through the one or more dispensing openings.
The combination of the rolling dispenser and the attached peripheral body provides many advantages for entertaining an animal as well as providing a reliable device for selectively dispensing treats. The peripheral body provides additional structure for a pet owner or an animal to grab or hold the device so that the rolling dispenser can be selectively controlled to dispense treats. For example, the one or more dispensing openings can be positioned so that gravity along with the rolling or spinning action of the rolling dispenser results in release of treats from within the dispenser.
Additionally, as the dispenser rolls, the location of the one or more dispensing openings changes with respect to the peripheral body. In some positions as the dispenser rolls, the one or more dispensing openings may be fully or partially obstructed by the interior curved engaging surface of the peripheral body to slow or to prevent treats from being dispensed. In other positions, none of the openings are obstructed which may therefore allow an increased rate of treat dispensing. Additionally, random movement of the peripheral body also provides some unpredictable or randomness in dispensing of treats, which may be more characteristic of how and animal interacts with the device. Generally however, the more intense rolling of the dispenser will result in greater amounts of treats being dispensed and therefore, the more vigorously and animal interacts with the pet toy, the greater reward potentially for receiving treats. Accordingly, and animal may learn to more vigorously play with the device to receive a greater number of treats.
The combination of the peripheral body and interior rolling dispenser visually resembles a gyroscope in which the interior rolling dispenser is similar to the rotor of a gyroscope. The peripheral body is similar to the gimbal of the gyroscope. However, functionally, one significant distinction is that the interior rolling dispenser rolls by frictional contact against a solid surface, namely, the ground while the peripheral body is maintained in a substantially fixed orientation with respect to the ground as the interior rolling dispenser rotates. In this regard, another conceptual way to view the pet toy of the invention is that, while the interior rolling dispenser and peripheral body look similar to a gyroscope, the manner in which the pet toy operates is reversed in that the interior rolling dispenser freely rotates while the peripheral body remains substantially stationary and thereby unaffected by the rotation of the interior rolling dispenser. In other words, while the peripheral body moves linearly after being contacted when the pet toy is lying on a surface such as the ground, the peripheral body remains substantially stationary in the sense that it does not rotate with the interior rolling dispenser.
Additional features and advantages of the invention will become apparent by review the following detailed description, taken in conjunction with the drawings.

The peripheral body 12 is also illustrated as being constructed of two sections or halves, an upper section 30 and a lower section 32. The upper and lower sections 30, 32 are attached to one another by opposing connectors, namely, male connectors 34 and female connectors 36.

The projections 44 also serve as a safety feature reducing the risk of an animal paw pad becoming lodged/trapped in the dispensing opening 16. Without the projections, a paw pad could compress and slip into the dispensing opening. For example, if an animal places its paw through the opening, the paw may re-expand and become trapped. With use of the projections, the ability of the paw pad to re-expand after entering the dispensing hole is greatly reduced or eliminated since the projections increase the effective depth of the opening and keeps the paw pad compressed, thereby allowing the pad to slide back out of the dispensing hole. In the event the animal does pass the paw pad completely through the dispensing opening 16 and beyond the projections 44, the gaps between the projections allows the animal's individual pads on the paw to naturally compress or be drawn toward one another causing the paw pad as a whole to return to a smaller compressed size so it can be withdrawn back through the dispensing opening.
Another factor that determines dispense rate is the type of treats which are loaded within the chamber 28. Accordingly, a pet owner may choose a type of treat that can be dispensed at a desired rate considering the rotational or spinning movement of the dispenser 14 that is likely to occur when the pet owner's animal plays with the toy.

The interior engaging surface 42 of the peripheral body 12 contacts a mid portion of the dispensing element 14. In one embodiment, a plane through a mid-point of the interior engaging surface 42 is substantially coplanar with a plane of a diameter of the dispensing element 14. The peripheral body 12 has a height that is perpendicular to a diameter forming major axis of the peripheral body. In one embodiment, the height of the peripheral body 12 is no greater than about half of the height (or diameter) of the dispensing element 14. Accordingly, a portion of the dispensing element 14 remains exposed and extends above an upper surface of the peripheral body 12 as the pet toy 10 is oriented in
Because of the cross sectional size of the curved interior engaging surface 42, when viewed from the cross section of
Although the pet toy 10 is illustrated with only one dispensing opening 16 it will be appreciated that they pet toy 10 may have any number of dispensing openings 16. For example, in one embodiment, each of the dispenser base 20 and the dispenser lid 22 have a dispensing opening 16. In another embodiment, two dispensing openings 16 are included in the dispenser lid 22. In yet another embodiment, two dispensing openings are arranged in one of the dispenser base and the dispenser lid. In still another embodiment, the pet toy 10 has two or more openings arranged such that at least one of the openings is always unobstructed by the interior engaging surface 42 of the peripheral body 12.
According to a method of the invention, a substantially stationary element 12 peripherally surrounds an interior dispensing element 14. The dispensing element 14 includes a chamber 28. Animal treats T may be loaded into the chamber 28 through an opening 16. The dispensing element 14 is selectively rolled or rotated to dispense the treats T. The stationary element 14 provides a contact surface to enable a pet owner or animal to cause the dispensing element 14 to spin or rotate in order to dispense treats T through the opening 16. The speed of rotation and amount of rotation over a period of time can be modified to affect the rate and amount of treats T dispensed. An animal will likely learn that the greater amount of interaction by contact with the stationary element 12 results in a greater number of treats T that are dispensed. Similarly, the greater amount of force applied to the stationary element 12 will likely result in a faster spinning or rotational movement of the interior dispensing element 14 which may also result in a greater number of treats T being dispensed. If great enough force is applied, the toy 10 may be completely flipped over, but because the exterior surface 40 of the interior dispensing element 14 is spherical, the toy 10 can be flipped over and still remain functional in that contact with the stationary element 12 will still result in some degree of spinning or rotational movement of the dispensing element 14.
Considering the above features of the invention, in one aspect, it may be considered a pet toy 10 with selective and controlled capability to dispense treats T by spinning or rotational movement of a dispensing element 14 continually engaged with a peripheral body or ring 12. In connection with this aspect, the invention may be more particularly considered a pet toy 10 comprising: a peripheral body 12; an interior dispensing element 14 maintaining contact with said peripheral body 12, and an opening 16 formed in said interior dispensing element 14 communicating with a chamber 28 of said interior dispensing element. Projections 44 may be interconnected to an interior surface of the dispensing element and arranged proximate to the opening 16. The projections may be of different sizes and heights to one or more of: alter the rate of dispense of treats T from the chamber 28; and prevent the paws, or paw pads, of animals from being lodged and/or trapped in the opening 16 of the chamber 28.
In another aspect of the invention, considering the above described method, it may be considered a method of dispensing treats T from a pet toy 10 comprising: providing a substantially stationary element 12 peripherally surrounding an interior dispensing element 14; applying force to said stationary element 12 to selectively rotate said dispensing element 14 while the dispensing element maintains engagement with said stationary element 12; and dispensing treats T from a chamber 28 of said dispensing element 14 out of an opening 16 in said dispensing element 14 as said dispensing element rotates.
In yet another aspect of the invention, it may be considered a combination of a treat dispensing pet toy 10 with treats T loaded within the pet toy. According to this aspect, it may be more particularly considered in combination, a pet toy 10 and treats T to be dispensed from the pet toy comprising: a peripheral body 12; an interior dispensing element 14 maintaining contact with said peripheral body 12, and an opening 16 formed in said interior dispensing element 14 communicating with a chamber 28 of said interior dispensing element 14 for holding one or more treats T therein.
Although the invention has been described with specific reference to one or more preferred embodiments, it shall be understood that the invention may be modified or changed commensurate with the scope of the claims appended hereto.
