DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] 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 an intake limiting pet food bowl construction as illustrated, and the steps described herein may be broadly, equivalently adapted to the production of the wide variety of pet product constructions envisioned above. As such, 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 of a preferred embodiment solely for the purposes of enabling an invention as understood at the time of filing and not of limitation.

[0028] In consideration of the above disclaimer, 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

[0029] Referring now to the drawings, wherein like reference numerals indicate the same parts throughout the several views, a pet food or water bowl, generally noted at 10 is shown according to a preferred embodiment of the present invention. FIG. 1-3 show a slow feed pet feeder bowl 10 (hereinafter synonymously referred to as bowl, pet bowl, feeder, pet feeder, and dish) according to a first configuration of the preferred embodiment of the present invention. The bowl 10 forms a containment volume 12 formed within a circumferential outer lip or rim 14. Traditional feed limiting pet food bowls formed of metal are limited by the mechanical application of metal working techniques, and as such result in a generally annular-shaped trough around a single or a small number of blunt upward protuberances which forces a pet to progressively move in a circular fashion there around while it eats. Utilizing the present invention, a containment volume 12 is formed having a plurality of upwardly disposed interference structures 16 that form a tortuous path configuration there between, which will similarly force the pet to progressively moved throughout the trough 12 in order to access the contents. Such impediments result in slower eating habits being forced into the pet's behaviors.

[0030] In the first configuration shown in FIG. 1-3, the interference structures 16 are formed in images having a first theme, herein shown as a dog theme with various imaged shaped structures 16. As shown in FIG. 4-6, the interference structures 18 are formed in images having a second theme, herein shown as an activity theme with various imaged shaped structures 18.

[0031] In either variant, the present invention provides the base structure of the pet related product, herein the bowl 10, formed initially of plastic. Numerous thermoplastic or thermoset resins may be utilized for forming an intricate pet product body structure in an economic and efficient manner while still imparting desired mechanical and processing functional characteristics. By way of example, and not meant as a limitation, these may include polystyrene (PS), polymethyl methacrylate (PMMA), acrylonitrile-butadiene-styrene (ABS), styrene-acrylonitrile (SAN) and polycarbonate (PC).

[0032] The selection of any particular resin would currently appear to be merely a design selection based upon product engineering and manufacturing effectiveness or optimization and having good physical properties and desirable flow, melt viscosity and molding characteristics from a production and manufacturing standpoint.

[0033] The bowl 10 may thereby be formed of a structurally sufficient plastic molded member having its general construction in accordance with the present invention. The pet product is preferably formed as a pet food or water bowl, but is not meant to be limited to such a form factor and may include food storage bins, elevated bid dog feeders, food scoops, litter scoops, litter boxes, housings for larger pet products and the like. In any embodiment variant the pet product is molded using injection molding, rotational molding, vacuum forming, blow molding, compression molding, thermoforming or other plastic forming techniques that can provide a structure having a shape that cannot be readily or economically shaped by metal stamping or other conventional metalworking method. A surface-coating layer 20 of metal is subsequently deposited on at least one of the surfaces of the pet product structure to impart the appearance, and at least partial functionality, of a metallic surface.

[0034] In the most preferred embodiment of the invention the metallic coating is applied to the side that is facing-up or otherwise functional as a feeder. The metallic coating 20 is very thin in relation to the bulk of the article (not shown to scale) and follows the contours on the surface of the part. The thickness of the metallic coating can vary depending upon the particular application, but for weight, cost and manufacturing time, a thin layer is preferred. Also, it should be readily apparent that depositing the metal layer on only one side of the article offers several economic advantages in comparison to coating the entire article. Firstly, there is a metallic material savings, as approximately only one-half of the surface area of the parts is metallized. Secondly, there is only one pass through the metallizer, and the parts are not subjected to the deposition mechanism twice to accommodate both sides. Thirdly, metallizing cycle-time is halved as it takes approximately half as long to deposit the metal on only one side of the parts. Finally, the process provides a simpler part handling, as the complex part handling mechanisms for turning/flipping the parts for metallizing both sides are avoided.

[0035] Metal coating on pet product article can be applied by any of the known vacuum deposition procedures. The semi finished plastic part is subjected to a metallizing process in an individualized non-contiguous manner, where a thin metallic layer is deposited on at least one of the product surfaces. Metallizing can occur through sputtering deposition, vapor deposition under vacuum, electroplating, auto catalytic or non-galvanic plating methods, or any hybrid, adapted or equivalent method. Vacuum metallization or deposition is the deposition of a film or coating in a vacuum or low-pressure plasma environment. The term plasma generally refers to an ion- or electron-rich gaseous environment for providing appreciable electrical conductivity. Vacuum deposition is a term that is applied to processes that deposit atoms or molecules one at a time, such as in physical vapor deposition (PVD) or low-pressure chemical vapor deposition (LPCVD).

[0036] The metallic coating may optionally be enhanced by subjecting the metal surface to a post-metallizing holding period or by applying a clear protective overcoat. The resultant pet product item simulates the appearance metal, and may provide the durability, cleanability and the general antimicrobial nature resulting metal surfaces.

[0037] In addition to the above features and benefits, a rubber bonded ring or rubber feet 22 may be provided to a lower surface of the outer edge of the bowl where the sidewall interfaces at a floor or supporting surface. In an alternate embodiment to the invention, the entire bottom portion of the bowl may comprise the rubber, non-skid surface.

[0038] In a preferred embodiment, the material chosen for the bonded ring or foot 22 is preferably a pliable material such as rubber, pastisol, or a polymer based material. In a preferred embodiment, the material is capable of providing resistance to the bowl 10 to substantially reduce slipping and/or sliding along the floor or other surface upon which it is placed.

2. Operation of the Preferred Embodiment

[0039] In operation, present invention provides a metallized plastic pet product, as well as a system and method for the production of low cost, durable pet products having high perceived quality features. Once a selected pet related product is formed initially of plastic, a metallized surface finish is applied to at least a part of at least one element of the plastic. In such a process, a structure having a shape that cannot be readily or economically shaped by metal stamping or other conventional metalworking method can be formed from injection or other molding and subsequently metallized. Products such as pet food bowls, water bowl, pet food storage bins, elevated feeders, a pet food scoops, litter scoops and even litter boxes may be provided for otherwise conventional use but including the objects, features and advantages of the present improvement.
