Patent Application
20110083608
The present invention relates to pet toys having the capability to dispense food or treats, and more particularly, to a treat dispenser and method wherein the animal may selectively dispense treats, and the dispenser includes a weighted base causing the toy to return to a normal upright position after being manipulated by the animal.
Interactive toys for pets have become quite popular. Animal behaviorists have validated many benefits to an animal that is stimulated, preoccupied, or otherwise engaged in productive interaction with a pet toy. Chew toys provide needed mastication for animals such as dogs. Throw toys provide overall physical exercise for dogs. Chew toys with treats provide both mastication and extended interaction since the animal's interest can be better maintained with the possibility of receiving an edible treat.
A number of inventions have been developed for increasing the length of time an animal may interact with a toy. Some of the inventions include pet toys that may enable food or treats to be dispensed from the toy. Toys with edible treats have proven to remediate separation anxiety experienced by some pets. By increasing the intensity and length of time the animal is occupied, the animal may be less prone to engage in negative behaviors.
One example of an animal food dispenser includes the invention disclosed in U.S. Pat. No. 6,526,912. This reference more specifically discloses a dispenser having a base portion and an upper portion defined by at least one wall enclosing a container cavity. An opening is formed in the upper portion to access the container cavity. A weighted body is fixed to the base of the dispenser, and provides a means for returning the dispenser to an upright position after the dispenser has been tipped or moved by the animal. The dispenser can be moved on a surface in an oscillating and/or sliding motion by the animal for dispensing a unit from the opening.
While the prior art may disclose various methods for dispensing treats or food, there is still a need to provide a treat dispensing device in which the animal has better control in selectively dispensing the treats. There is also a need to provide a device that is made simpler for loading the treats and cleaning the device. There is also a need to provide a device so that the movement or action of the device can be varied based upon a selected amount of weight that is placed in the base, and that can be adjusted by the user. Finally, there is also a need to provide the aforementioned improvements/advantages in a structurally simple, yet reliable construction.
In accordance with the present invention, a treat or food dispensing device and method are provided to enable an animal to selectively dispense treats/food from the device. The word “treat” hereinafter is meant to include all animal foodstuffs that can be consumed by an animal. Treats may take various forms such as uniformly sized nuggets or the treats can be irregularly sized and shaped.
In accordance with the device of the present invention, a dispenser is provided having a body, a base, and an interconnecting assembly or piece that interconnects the body to the base. The body is preferably hollow, and receives treats as loaded therein by the pet owner or caregiver. A weighted material is loaded in the base. Preferably, the weighted material is capable of shifting or moving in the base and is therefore not fixed to the base. The material used can be, for example, sand or other granular material, or ball bearings. The base is filled with a desired amount of the material to maintain the toy in an upright position and to return the toy to the upright position after being tipped or displaced. The interconnecting assembly includes an integral cover that covers the weighted material within the base. The upper end of the interconnecting assembly may be threadably engaged with the lower portion of the body. An opening of a desired shape and size is formed in the body to allow dispensing of treats retained within the body.
In accordance with the method of the present invention, a selected amount of weighted material is placed in the base. The amount of weighted material can be selected to adjust the movement and oscillation characteristics of the device when contacted by the animal. The selected amount of weighted material dictates the manner in which the device will return to its normal upright position after being contacted by an animal. For example, the greater amount of weighted material present, the greater the amount of force required to tip the device. Reducing the amount of weighted material in the base allows the device to be more easily tipped or moved. The longer time period in which the device is tipped may provide greater opportunity for dispensing of treats held within the body. The particular manner in which the device oscillates after being contacted is also affected by the amount of weight placed within the base. Another factor determining the oscillation characteristics of the device is the amount of space or gap between the cover of the interconnecting piece and the top surface of the weighted material. A greater cavity size enables greater shifting and movement of the weighted material, and also generally results in the device staying in a tipped or angled position for a greater amount of time. Thus, in addition to adjusting the amount of weighted material present, a user may also adjust the volume of the weighted material in order modify the oscillation and movement characteristics of the device.
Other features and advantages of the present invention will become apparent from a review of the following detailed description, taken in conjunction with the drawings.
The present invention will now be further described in the Detailed Description which follows with reference being made to the following drawings in which:
The body 12 as viewed in
Referring to the base 14, it includes a sidewall 15, a substantially flat lower surface 44, an upper edge 24, and an interior cavity 26 that is adapted to receive a weighted material, as discussed further below with respect to
The interconnecting piece or assembly 28 is characterized by an upper extension 37, and a plurality of threads 38 formed on the upper extension 37. A flange 30 forms a lower portion of the assembly 28, and a peripheral lower extension 32 protrudes from the flange 30.
Also referring to
A desired amount and type of granular material is placed within the cavity 26 of the base 14. The weight and volume of the granular material will dictate the motion/oscillation of the device when tipped. A heavier material placed within the base will make the device more difficult to tip and therefore, more difficult to dispense treats that may reside at an elevation below the level of the opening 40. Placing a lesser volume of granular material within the cavity 26 enables the granular material to more easily shift or move in the direction the device is tipped or displaced, thereby allowing the device to be placed in the tipped position for a longer period of time prior to the device rotating or oscillating back to its upright position. This particular aspect of the invention may be advantageous for increasing the dispense rate of the toy. In any event, the weighted material of the present invention is not fixed to the base and is allowed to naturally shift or move according to the contact made by the animal with the device.
In order to load treats within the body, the body 12 is simply unscrewed from the interconnecting assembly 28, treats are placed within the interior opening of the body 12, and then the body 12 is reattached to the interconnecting assembly 28.
Based upon the foregoing, a treat dispensing device and method are provided for selectively dispensing treats by action of an animal. The tipping action or motion of the device can be altered by varying the amount and type of weighted material that is placed within the base. The removable aspect of the base with respect to the body enables a pet owner or caregiver to easily charge or load the body with treats. This feature also allows better interior access to clean the device.
Although only one treat opening 40 is illustrated in the preferred embodiment, it shall be understood that additional openings 40 can be formed on the body, and spaced at different locations around the body in order to provide additional opportunities for treats to be dispensed from the device.
Although the present invention has been disclosed in a preferred embodiment, it shall be understood that various other changes and modifications can be made to the invention in accordance with the scope of the claims appended hereto.
