Description

- I -MOLDED OR EXTRUDED CATNIP COMPOSITE AND METHOD OF
MANUFACTURING COMPRESSED CATNIP PET TOYS AND PET TOYS MADE
FROM THE SAME
BACKGROUND OF THE INVENTION
1. Field of the Invention [0001] The present invention relates generally to pet products that include the delivery of aromatic attractant for encouraging pet interaction and, more particularly, to such a pet products formed of a catnip composite and a method for making the same.

2. Description of the Related Art [0002] Nepeta cataria, commonly known as catnip, or catswort or catmint, is a herbaceous perennial, resembling a mint in appearance, that is widely naturalized elsewhere, as well as commercially grown for specialty purposes. It is commonly used in herbal tea blends related to sleep, stress reduction, and relaxation, as well as used as a culinary herb for cooking and many dishes.

[0003] The plant terpenoid nepetalactone is the main chemical constituent of the essential oil of Nepeta cataria (and some other species within the genus Nepeta). This essential oil is known for their behavioral effects on the cat family, and especially on domestic cats. Nepetalactone acts as the behavioral attractant, with the chemical entering the feline's nose and stimulating the olfactory receptors. Other plants that also have this effect on cats include valerian (Valeriana officinalis) and plants that contain actinidine.

[0004] Used as a recreational substance for pet cats' enjoyment, catnip and catnip-laced products are designed for use with domesticated cats and are available to consumers. Used generally as an attractant to encourage play and interaction, catnip commonly causes domesticated felines to rub on the plant, roll on the ground, pawing at it, licking it, and chewing it. Consuming catnip is often followed by drooling, sleepiness, anxiety, leaping about and purring.

[0005] There are many pet toys available that incorporate these effects to provide entertainment to the pet and the owner. The most direct method of forming such toys is to compress chopped catnip material directly into the shape of a pet toy itself. As first described in U.S. Patent No. 1,022,113, issued in the name of Smith, a ball made entirely of compressed catnip is described, as well as a ball formed of wood, rubber, papier-mache or wood pulp pressed into a shape and formed with recesses that are filled with catnip compount. More recently, numerous design patents exist for compressed catnip pet toys formed into various shapes.

[0006] It is still another object of the present invention to provide a composite material that is naturally hydrophobic.

[0007] It is still yet another object of the present invention to provide for use of durable, warm, soft, skid resistant and resilient material for use in conjunction with domestic pet products that is formed substantially of natural ingredients.

[0008] It is yet still another object of the present invention to provide for the use of a catnip composite material that results in a soft, textured "feel" that can be grasped, clawed or chewed in a manner that is positively received by domestic pets.

[0009] Further, the present invention provides a hydrophobic, naturally mold resistant, nontoxic material that can be robustly incorporated into a variety of pet products and product surfaces

[0010] Further still, the present invention provide a material that has a long lasting, positive aroma for domestic pets that can encourage use and interaction with those pet related products incorporating such material.

[0011] Such toys are popular for their efficacy, but the cost of the plant material results in only small sized devices being commercially available, requires that such devices durations. As such, these toys often provide for the replenishment of catnip, either in the form of solid or liquid extract, into or within the toy for subsequent dispensing based on movement or rotation of the toy or its interaction with the surrounding air. The present invention is markedly different by providing a less expensive aromatic composite material that can be molded, compressed, extruded, or otherwise shaped into small or large structures economically for extended delivery of an effective rate of aromatic compounds efficacy.

[0012] This, among other disclosed advantages and features, overcome many of the deficiencies outlined and inherent within the known prior art.
SUMMARY OF THE INVENTION

[0013] Therefore, it is an object of the present invention to provide a catnip composite and a method for making the same.

[0014] It is another object of the present invention to provide for such a catnip composite used to produce domestic pet toys and other pet products.

[0015] It is yet another object of the present invention to provide a catnip composite material capable of being molded, compressed, extruded or otherwise shaped into small or large sheets or bodies of aromatic attractant material.

[0016] As described in one embodiment of the present invention, a catnip-cork composite material is provided that is capable of being molded, compressed, extruded or similarly processed into small or large bodies or sheets and allow for the economic manufacture of toys and products for domestic pets, especially felines. Dried and granulated catnip (or similar olfactory attractant) is blended with a fill material such as powdered or granulated agglomerate cork material that is typically a waste product of cork stopper manufacturing. It is envisioned that similar materials can be alternately used, such as, for example, waste cedar wood shavings or sawdust or other types of lignocellulose material. The use of various types of low cost waste products or woody biomass materials have been found to effectively extend the economic viability of the compression molded catnip products available in the prior art. The blended chipped, granulated or powdered materials are then mixed with a bonding agent. An effective bonding agent has been found in the use of lignosufates.
Lignosulfates can also be obtained as a recovered waste product from the wood or paper pulping industries, and further will make the completed product of an "all natural"
construction. Other effective bonding agents are known and can be uses, such as, for example, polyurethane food grade adhesives.

[0017] As described above, a low cost, all (or substantially) natural composite material can be formed economically into various shapes. The blended, bonded material can be extruded, compressed or molded into shapes or sheets, and given the economy of using a composite material whose components have an overall lower blended cost that a material made substantially of 100% molded catnip, it is now possible to make much larger bodies, be it pet toys or larger structures, such as claw scratching posts, that provide the attractant benefit to the domestic feline of catnip.

[0018] The foregoing and other aspects will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawing figures.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] The best mode for carrying out the invention is presented in terms of its preferred embodiment, herein depicted within the Figures.
1. Detailed Description of the Figures

[0031] Before explaining the present invention in detail, it is important to understand that the invention is not limited in its application to the details of the construction illustrated and the formulations described herein. The invention is capable of other embodiments and of being practiced or carried out in a variety of ways. It is to be understood that the phraseology and terminology employed herein is for the purpose of description and not of limitation.

[0032] In the following detailed description of a first preferred embodiment and a second preferred embodiment of the present invention, reference is made to the accompanying drawings which, in conjunction with this detailed description, illustrate and describe a first preferred embodiment and a second preferred embodiment of a pet toy ball feeder in accordance with the present invention. Referring now to the drawings, in which like-referenced characters represent corresponding elements throughout the several views, attention is first directed to FIG. 1 and FIG. 2, a composite material is shown being formed and formed, respectively, of three main components:
a solid attractant 10; a lignocellulose filler material 20;
and a binding agent 30.

[0033] A solid attractant 10 is preferably a dried and granulated catnip. It should be obvious to a person having ordinary skill in the relevant art, in light of the present teachings, that equivalent replacements for dried and granulated catnip can be utilized, including, but not limited to, any plant containing a terpenoid nepetalactone or similar chemical to the essential oil of Nepeta cataria and other species within the genus Nepeta, as well as other

[0034] It is anticipated that other additives may be incorporated to accommodate particular uses or design choices, such as, for example, the incorporation of dyes in order to provide colors or otherwise alter the aesthetic of the final article. Other functional additives, such as odor absorbing materials, can further be incorporated into the agglomerated finished composite material. Such odor absorbing materials may include bentonite, zeolite, or other clays or odor absorbant materials. Again, the selection and function of such additional additives will be more apparent in conjunction with the additional description below.

[0035] A solid attractant 10 is preferably a dried and granulated catnip. It should be obvious to a person having ordinary skill in the relevant art, in light of the present teachings, that equivalent replacements for dried and granulated catnip can be utilized, including, but not limited to, any plant containing a terpenoid nepetalactone or similar chemical to the essential oil of Nepeta cataria and other species within the genus Nepeta, as well as other plants that are known to have effects on cats, including valerian (Valeriana officinalis) and plants that contain act inidine.

[0036] The lignocellulose filler material 20 is preferably granulated or agglomerated cork. Cork is commercially harvested from the bark tissue of the Cork Oak (i.e. Quercus suber). While a majority of the cork harvest is used each year in the manufacture of wine bottle stoppers and other closures, for the purpose of the present invention it is intended that less value added waste streams from such production be re-purposed. As such, it is intended that flaked, chipped, ground, agglomerate or manufacturing "dust" from other cork manufacturing processes are to be sourced and reused as the filler material 20 of the present invention. To date, such "powder" created from grinding or cutting in cork manufacturing has been burned in boilers for steam and energy production.

[0037] It should be obvious to a person having ordinary skill in the relevant art, in light of the present teachings, that equivalent replacements for ground or agglomerated cork can be utilized, including, but not limited to, any plant containing lignocellulase such as, by way of example and not meant as a limitation, sawdust, wood chips, wood pellets or wood shavings of any type, such as cedar, pine, or the like, as well as various woody biomass materials. The use of cedar or pine is preferred as an alternate material in that these all natural materials are already utilized in domestic pet products, such as for use in cat litter or small animal bedding, and their use is generally accepted by both pets and pet owners.

[0038] In the preferred embodiment, the binding agent 30 can be a lignosulfate binder, which has been found to be an effective bonding agent for both dried and ground catnip as well as for cork. Other effective bonding agents are known and can be uses, such as, for example, various thermoplastic resins and polyurethane food grade adhesives.
2. Operation of the Preferred Embodiment

[0039] As described in the present invention, a catnip-cork composite material is provided that is capable of being molded, compressed, extruded or similarly processed into small or large bodies or sheets and allow for the economic manufacture of toys and products for domestic pets, especially felines. As described above, a low cost, all (or substantially) natural composite material can be formed economically into various shapes. The blended, bonded material can be extruded, compressed or molded into shapes or sheets, and given the economy of using a composite material whose components have an overall lower blended cost that a material made substantially of 100%
molded catnip, it is now possible to make much larger bodies, be it pet toys or larger structures, such as claw scratching posts, that provide the attractant benefit to the domestic feline of catnip.

[0040] Referring now to FIG. 3 through FIG. 5, an exemplary design for a cover 50 for use with a pet feeder or water bowl 52 is shown made according to the preferred embodiment of the present invention. In this exemplary design, a pet food and/or water bowl 52, such as a plastic or stainless steel pet feeder, is shown in conjunction with a cork composite material cover 50 that is preferably durable and lightweight, and provides an aesthetically pleasing appearance, protection to both the bowl and the surface on which the bowl may be set upon, and possibly some insulating properties to the contents placed therein.
The use of a composite material incorporating a catnip or functional equivalent solid attractant may be agglomerated with a cork filler material and molded with a binding agent to provide a domestic pet feeder that is attractive to domestic pets, especially felines. Further, the consistency and texture of the cover 50 is quiet when contacted with hard surfaces, unlike a molded plastic body.
Further, it is formed of a closed cellular structure that is hydrophobic and inhibits mold growth. The cover 50 may be placed about at least a portion of an exterior of the bowl, or completely encase the bowl sidewall. The cover 50 can remaining affixed to the bowl, or merely contact the bowl through an interference or friction contact fit.
Further, an adhesive may be placed between the exterior of the bowl and the interior of the cover.

[0041] As shown in conjunction with FIG. 6a and FIG. 6b, exemplary designs for underlayment mats 58 are shown for use in conjunction with a small animal litter box 60 (FIG.
6a) or a pet feeder or water bowl (FIG. 6b), and incorporating the composite material according to the preferred embodiment of the present invention. The cork-catnip materials can further incorporate odor absorbing materials, as described above, to counteract the odors generated by use of a small animal litter box. Further still, the natural hydrophobicity of the cork materials will prevent water damage due to spills or overflow from the pet food and water bowls 62.

[0042] As shown in conjunction with FIG. 7a through FIG.
7d, exemplary designs for domestic cat scratchers are shown incorporating the composite material according to the preferred embodiment of the present invention. The cork-catnip composite material can be affixed as a functional surface element 72, as shown in FIG. 7b through FIG. 7d, or as assembled into a scratching post design 70, as shown in FIG. 7a.

[0043] As shown in FIG. 8a through FIG. 8d, domestic pet furniture 80 of alternate exemplary designs are shown further formed of the composite material according to the preferred embodiment of the present invention.

[0044] The foregoing descriptions of specific embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teaching.
The embodiments were chosen and described in order to best explain the principles of the invention and its practical application, to thereby enable others skilled in the art to best utilize the invention and various embodiments with various modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the Claims appended hereto and their equivalents. Therefore, the scope of the invention is to be limited only by the following claims.
