Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] FIG. 1 illustrates one embodiment of the anti-microbial packaging of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] One embodiment of an anti-microbial packaging assembly 10 is shown in FIG. 1. As shown in FIG. 1, the anti-microbial packaging assembly 10 includes a decontamination layer 12. The decontamination layer 12 is designed to be the innermost layer of the anti-microbial packaging assembly 10, such that the decontamination layer 12 may come into touching contact with any item placed within the anti-microbial packaging assembly 10.

[0017] As illustrated in FIG. 1, the decontamination layer 12 is preferably formed as a thin deposition of copper, owing to the well-known anti-microbial characteristics of copper and copper-containing alloys. The copper may be included in the anti-microbial packaging assembly 10 as a stand-alone, thin sheet of a copper/copper-alloy metal, or in a preferred embodiment, the copper/copper-alloy may be deposited (via any known process) on a film substrate layer 14, as shown in FIG. 1. The film layer 14, while not required, does provide a certain measure of puncture resistance and stiffness to the overall anti-microbial packaging assembly 10.

[0018] It is another aspect of the present invention that that copper/copper-alloy layer may applied via a vacuum deposition process, or alternatively via any other known deposition process, upon a substrate film layer 14.

[0019] As also shown in FIG. 1, the decontamination layer 12 and the underlying film substrate 14 are fixed to one side of a paper substrate 16 via a suitable adhesive material/layer 18.

[0020] In a preferred embodiment of the present invention, the paper substrate 16 is also provided with a second adhesive material/layer 20 which supports on its opposing side a deposition or thin metallic layer 22, preferably of aluminum.

[0021] It is an important aspect of the present invention to note that the metallic layer 22 not only provides a measure of RFID blocking to the anti-microbial packaging assembly 10 as a whole, but may also be utilized for the deposition of any suitable design or adornment, such as holographic imaging or the like. Moreover, the metallic layer 22 may be expressed as a thin-film created through transferred metallization to be as thin as 1 micron, or between 0.000225″-0.004″ of deposited aluminum, with or without holographic imaging thereon.

[0022] As will be appreciated, the metallic layer 22 acts as a barrier, generally speaking, and could also be composed of another layer of copper or copper-containing alloys.

[0023] Returning to FIG. 1, and in a preferred embodiment of the present invention, the decontamination layer 12 may be formed via the vacuum deposition of copper or a copper-alloy on the film layer 14, thus evidencing a thickness of between 300-400 angstroms. The film layer itself is formed from a plastic/polymer film material and may be of any desired thickness, but may be preferably as thin as 0.000225″, or as thick as 0.004″.

[0024] For its part, the paper layer 16 is preferably as thin as typical tissue paper, or as thick as 100 pt multi-ply paper, in dependence upon the nature and purpose of the anti-microbial packaging assembly 10.

[0025] As will be appreciated by one of ordinary skill, the paper layer 16 provides a measure of stiffness and machinability to the anti-microbial packaging assembly 10 as a whole. The paper layer 16 may also express tear resistant attributes and characteristics, acting therefore more as a fabric, without departing from the broader aspects of the present invention. The material of the paper layer 16 may itself be impregnated with an anti-microbial agent, without departing from the broader aspects of the present invention.

[0026] As a final layer, and especially as it relates to the packaging of various food stuffs, the anti-microbial packaging assembly 10 may also enjoy an outer polymer coating layer 24. This polymer layer 24 can be crafted from any water-repellant and non-porous material without departing from the broader aspects of the resent invention. The polymer layer 24 is preferably transparent or translucent, so that any designs or holographic patterns printed or deposited upon the metallic layer 22 may be easily visible and discernable. As will be appreciated, the polymer layer 24 also provides impact protection to the anti-microbial packaging assembly 10, while also providing external printability and glueability to the anti-microbial packaging assembly 10.

[0027] As therefore shown in FIG. 1, and in accordance with one embodiment of the present invention, the anti-microbial packaging assembly 10 preferably contains the following layers: the inner decontamination layer 12 supported on the film 14; the adhesive layer 18; the paper layer 16; the second adhesive layer 20; the metallic film layer 22, and finally, the outer polymer layer 24.

[0028] In practice, a laminate construction such as the anti-microbial packaging assembly 10 and shown in FIG. 1 may be formed in any shape or size to accommodate various food items, credit cards, bank cards, driver's licenses or any other object having a surface that may benefit from the sanitizing properties of the present anti-microbial packaging assembly 10.

[0029] Once formed into a suitable package, the anti-microbial packaging assembly 10 may releasably house any number of food items, or other objects, such that the exterior of these objects becomes incident upon and in touching contact with the decontamination layer 12, thereby effecting a sanitizing affect upon this outer surface.

[0030] While a preferred anti-microbial packaging assembly 10 is shown in FIG. 1, it will be readily appreciated by one of ordinary skill that modifications of the laminate shown in FIG. 1 may be altered, without departing from the broader aspects of the present invention.

[0031] In particular, not all of the layers shown in FIG. 1 are necessary in the final laminate, in accordance with the intended use of the same. That is, provided that the anti-microbial packaging assembly 10 includes an inner decontamination layer 12, laminated or supported on any chosen substrate, the exact nature and number of layers is largely driven by manufacturing requirements and the specific items that are intended to be housed within the anti-microbial packaging assembly 10.

[0032] Thus, alternative embodiment of the present invention may not include, e.g., the metallic layer 22, or the polymer coating layer 24 or even the film layer 14, without departing from the broader aspects of the present invention. Moreover, other metals besides copper or copper-containing alloys may be used to form the decontamination layer 12, such as the use of silver-based metals, also without departing from the broader aspects of the present invention.

[0033] Still yet another preferred embodiment of the present invention lies in the potential differing topographies of the deposited/thin sheet of the decontamination layer 12. Thus, this decontamination layer 12 may be applied so as to evidence a substantially smooth surface, while alternatively, it may be desirable to form the inner decontamination layer 12 instead to evidence a honeycomb pattern.

[0034] By way of example, the anti-microbial packaging assembly 10 of the present invention may be crafted as a slim card holder, for use in accommodating credit cards, bank cards, driver's licenses or the like, such that the insert and storage of these items within the anti-microbial packaging assembly 10 facilitates the decontamination of these items, through the physical contact of the inner decontamination layer 12 with the items. Thus, and provided the anti-microbial packaging card holder assembly includes at least the inner decontamination layer 12, any card holder (or, indeed, any other or type of packaging) so manufactured may evidence a paper outer layer, or a polymer outer layer, without departing from the broader aspects of the present invention.

[0035] The range of possible packaging that could be advantaged through the use of a decontamination layer such as shown in FIG. 1, is quite large. Indeed, the present invention envisions, e.g., mail envelopes or money holders or card holders, having an inner decontamination layer and an outer bare paper layer, or plastic (film/polymer) coated paper layer. Packaging for food stuffs, or medical or pharmaceutical materials, are also envisioned, and whose application may favor utilizing the outer polymer layer 24 of the present invention. With all potential laminates of the present anti-microbial packaging assembly, it is possible to include one or more metallic layers 22 to provide additional RFID or anti-microbial protection, as well as to support fanciful or decorative holographic (or other) imaging thereon.

[0036] Although this invention has been shown and described with respect to the detailed embodiments thereof, it will be understood by those of skill in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed in the above detailed description, but that the invention will include all embodiments falling within the scope of this disclosure.
