Abstract
A sheet of material exhibiting a decorative floral pattern is used as a protective plant covering in conjunction with a plurality of removable fasteners. The sheet has a peripheral edge preferably defining an area sized to permit wrapping of the sheet in full, uncut form around a single, larger plant, or cutting of the sheet into multiple pieces to wrap a plurality of smaller plants on an individual basis. A non-woven material may be used so that it will not unravel if cut into sections. The material may also be at least semi-transparent to permit floral features of the plant to show through so that the material is less conspicuous when installed. Preferably a design element defining a cell is used having an area substantially less than that of the sheet, which is then replicated in a repeating manner to permit slitting, sectioning, and installation without regard for the orientation of the design. To assist the installed sheet in appearing more visually convincing, a process of producing the final product may include the steps of generating an image of a living plant, converting the image into a form suitable for printing, and printing the converted image onto the sheet.
To correct for compression of the image on either side when the sheet is wrapped around a plant, the aspect ratio of the image may be adjusted so that the printed image appears more life-like when the sheet is wrapped around the plant.

Description
_-DECORATIVE PLANT COVER
This invention relates generally to protective coverings for plants, bushes, shrubbery, and so forth during harsh or cold weather, and, more particularly, to an improved, more aesthetic covering which is more conformal to the shape of the plant to be protected, and one which is more easily stored during periods of non-use.
During harsh or cold weather, it is a good practice to protect plants from the wind nd the elements.
Although some gardeners believe it is advantageous to "keep a plant warm," this is actually incorrect. In fact, if a plant is allowed to warm up at the wrong time, premature spring growth may occur, resulting in dieback in the event of a cold snap. Without protection, winter plant injury may be caused by severe cold or loss of moisture from shoots or branches. Although it is normal for plant moisture to slowly evaporate throughout the winter, during periods of bright winter sunshine, the effect of strong winds may accelerate this drying process to an unacceptable level.
Thus, is it best to protect plants from fluctuations in temperature, which may be accomplished through~some form of wind-break. Two devices currently used for this purpose, burlap and Styrofoam "rose cones,"
both have drawbacks. Burlap is dirty, difficult to drape over plants without an additional supporting structure, and ' CA 02273455 1999-06-02 it eventually rots out. Also, its darker color may absorb solar energy and cause unwanted heating, particularly if wrapped too tightly.
The typical rose cone, shown in Figure 1, is unattractive and non-recyclable. Although these units are designed to be stacked on top of one another, being rigid and non-collapsible, they consume a considerable amount of volume when stored. In addition, the cone or pyramid shape defined by the interior of such covers is not conformal to the shape of most plants, forcing users to prune the plant in an undesirable way just to fit the cover over the plant.
The present invention overcomes limitations of existing devices and techniques by provi~ing a protective plant covering comprising a sheet of flexible material having two opposing side edges, and a plurality of fasteners, such that, with the material wrapped around the plant, the two side edges may be brought proximate to one another and adjustably fastened around and in physical conformity with the plant using the fasteners.
In the preferred embodiment, a durable sheet of material is provided having' a decorative floral pattern imprinted onto at least one side thereof. The sheet has a peripheral edge preferably defining an area sized to permit wrapping of the sheet in full, uncut form around a single, larger plant, or cutting of the sheet into multiple pieces to wrap a plurality of smaller plants on an individual basis. A non-woven material may be used so that it will not unravel if cut into sections. The material may also be at least semi-transparent to permit floral features of the plant to show through so that the material is less conspicuous when installed. The fasteners, which are preferably removable, may take the form of safety-pin type fasteners, clothes-pin type fasteners, skewers or other devices that may be selectively re-postioned onto the sheet to enhance conformity with the shape of the plant during installation.
The decorative floral pattern may be applied using silk-screening, flexographic printing, or other known processes. Preferably a design element defining a cell is used having an area substantially less than that of the sheet, which is then replicated in a repeating manner to permit slitting, sectioning, and installation without regard for the orientation of the design. If the material used is sufficiently porous, the ink used for printing will also bleed through, enabling the sheet to be installed with either side facing outwardly without visual ill-effects.
To cause the installed sheet to appear more convincing, a process of producing the final product may include the steps of generating an image of a living plant, converting the image into a form suitable for printing, and printing the converted image onto the sheet. To correct for compression of the image on either side when the image is gathered, the aspect ratio of the image may be adjusted so that the printed image appears more life-like when the sheet is wrapped around the plant.

Figure 7C is a drawing which shows how a plurality of images may be gathered from different angles.
Now making reference again t~ the drawings, Figure 2 illustrates a plant wrap according to the invention indicated generally at 20 in unfolded form.
Definitionally, the wrap 20 comprises a flexible sheet of material 22 having a top.edge 23, a bottom edge 24, and two side edges 25 and 26, respectively. The sheet is preferably provided such that the edges define an area large enough to wrap around a single larger plant such as a rhododendron; magnolia, evergreen or small tree, or sectioned into pieces to cover a plurality of smaller rose bushes, azaleas, and so forth.
In a preferred embodiment, the sheet is imprinted with a decorative floral pattern created through the replication of cells creating a continuous pattern that may be cut or sectioned along any direction without. noticeable visual ill-affect.
Figure 3 illustrates a covering according to the invention now installed onto a plant to be protected. Some advantages of the covering, shown generally at 30, are evident when the material is in place. In practice, during the installation process, the fasteners (32) may first be used to close the bottom portion of the material, then, the outer edge of the material may be overlapped or rolled to close the fasteners in bottom-up fashion until the top is reached . When the top of the material has been reached, the fasteners associated with the upper edge 23, may be used to create an enclosed wrap around the entire plant.
Fasteners associated with the lower edge of the material may also be used to "cinch-up" the bottom edge of the material around the base of the plant. Conveniently, any unused fasteners may simply be left attached to the fabric during use or storage.
Among other advantages of the invention are that, in contrast to existing rigid devices, mulch may be easily added, particularly if the wrapping is secured around the bottom and worked upwardly, in which case the mulching material can simply continue to be packed in and around the plant, until the top edge is either closed or left open, at the user's option. Additionally, portions of the plant being protected may protrude through the covering of the invention, if the user chooses to have such features remain exposed instead of pruning them off. As one example, a climbing rose may simply be left on a trellis without having to trim it off. For that matter, the wrap according to the invention may be placed around th. trellis itself, thereby eliminating the need to disturb plants in their growing environment.
In terms of materials, the wrap is preferably composed of a non-woven material such as spun-bonded polypropylene or other synthetic fabrics, including "CLAF."
Such materials offer certain advantages, including a breathable nature, and the ability to make cuts in the material, if desired, for better conformity with a plant structure, without the risk of tearing, as there is no "grain." The lightest-weight versions also tend to be at least semi-transparent. In addition, in the event that silk-screening is used to apply the visual indicia, it has ' CA 02273455 1999-06-02 been found that, although the material does not withstand high oven temperatures for ink drying purposes, water-based and vinyl inks nevertheless penetrate entirely through the material, resulting in a very permanent design pattern. It should be apparent that various other materials, both organic and inorganic, may function equally well according to the invention. In particular, recycled plastics of different compositions may be used, and, in place of silk screening the outer design, different colors of plastic may simply be melted together to create floral imagery, for example.
Now turning to Figure 4, an advantage of the invention is that multiple sheets may be joined along their edges, both horizontally and vertically, to accommodate larger plants or groupings of plants. For example, multiple sheets may be joined vertically to surround tall, narrow evergreens such as climbing roses, arbor vitae, and the like, or, the sheets may be joined horizontally, to accommodate plants with larger girths such as certain types of spruce, quince, and so forth. As shown in Figure 4, a plurality of sheets may be joined both horizontally and vertically for even larger plant types, including tree trunks.
Figures 5A to 5T illustrate various alternative fasteners which may be used according to the invention, with the understanding that other fastener types are also applicable. Figure 5A illustrates the use of a string and one or more capture devices, preferably in the form of a two-part disk. One portion of each disk, 51, is bonded or _ g _ adhered to the outer surface of the wrapping material, whereas a second portion 52 is preferably attached to the first portion 51 through the use of a rivet 53. Various materials may be used for the string-capture device, such as vinyl or other plastics, and the rivet may also be plastic, or metal or other suitable alternatives.
The string-capture structure consisting of elements 51, 52 and 53 may be made as a unit and glued onto the outer surface of the wrapping material, with the portion 51 preferably including a number of small apertures, around its periphery, for example, enabling the adhesive, such as hot-melt glue, to seep through a provide a better bond. Alternatively, an additional disk may be placed on the inner side of the material, with the rivet 53 being applied through the entire stack of elements, so as to bind the resulting structure on both sides of the wrap for a strong attachment.
Various other bonding mechanisms may be used, with the general principle being that, in the preferred embodiment, the fasteners may undergo quite a bit of use without compromising their structural integrity. As mentioned earlier, the string used in conjunction with the capture devices may either be provide separately, in which case it will be wound around two or more of the capture devices to provide closure or, alternatively, the strings may be made available through a separate attachment to the material itself. That is, without necessarily using a capture device as the point where the string actually attaches to the material.
Figures 5B and 5C illustrate hook-and-loop or Velcro-type material in use as a closure mechanism, noting that at least one aspect (54) may be provided in a vertical manner as opposed to a horizontal stripe. Figure 5D shows how buttons may be used. As with the string-capture devices of, Figure 5A, reinforcement areas 55 are preferably used to ensure that the buttons do not pull off or that the slots do not readily tear. Figures 5E and 5F illustrate the use of plastic barb-type connector mechanisms, whereas Figures 5G and 5H illustrate the use of ball-capture-type devices. Figure 5I shows how coated metal wires or "twister ties" may be used, whereas Figure 5J shows how strings, without capture devices, may alternatively be employed.
In the event that the invention is intended to be discarded after use, permanent, as wE~l as temporary clasure devices may be used, including adhesive tape, as shown in Figure SK. Disposable versions of the invention are preferably made with a biodegradable material such as cellulose fiber that decomposes after one season. In Figure 5L, plastic snaps are used to adjustably claw the material around the plant to be protected. Figure 5M shows the use of a buckle; Figure 5N shows the use of a string and eyelets; Figure 50 shows the eyelets in use with a spring-loaded type of manually adjustable capture device;
and Figure 5P illustrates how slits and removable pegs or other elements may alternatively be utili~ed.
Figure 5Q illustrates how the removable element segment of Figure 5P may, in fact, represent a portion of a longer elongated element such as a spike, nail, skewer or stake, preferably having a sharpened or semi-sharpened distal end 56 and a proximal end featuring some sort of loop or bend 57 to ensure that the device does not penetrate and fall through the overlapped material sheets.
Figure 5R illustrates yet a further example of the removal fastener of Figure 5P, wherein the peg of Figure 5P forms part of a safety-pin fastener or kilt ~in which may be opened for installation and closed upon itself for securement. Such safety-pin fasteners are available in a variety of wire thicknesses, and usually contain an outer zinc, tin, brass or chrome plating to assist with rust prevention. Even large diaper pins or stapling may be used as alternatives.
Figure 5S shows yet a further alternative fastener according to the invention, in this case a spring clip preferably having jaws with teeth to grab the material when installed. Spring-steel "binder clips" may be used, so may certain types of hair clips, though a sufficiently strong spring should be incorporated into the device to guarantee holding power throughout seasons of bad weather.
Figure 5T illustrates how, instead of a spring-loaded clip of the type shown in Figure 55, a clip having a separable applier may instead be used. In this case a tool 58 of some kind is used to spread apart, or to close a clip 59 again, preferably having teeth, with the tool being removed once the clip is in place. Certain types of garment fasteners are suitable according to this alternative embodiment, as are industrial versions of the types of fasteners used for "ace bandages," and the like.
Although the wrap may be constructed of single-ply material, multiple plies may alternatively be employed with or without an air gap (Figures 6B and 6A, respectively) to create a more insulating barrier.
Specifically, two or more plies of material may be quilted together as shown in Figure 6C, with the internal pockets formed thereby being left unfilled, that is containing only air. Indeed, in one embodiment of the invention certain types of commercially available bubble-wrap materials may be used. As an alternative to air-filled pockets, a second, insulating layer may be bonded to a decorative outer material, as illustrated in Figure 6D. For example, a layer of closed- or open-cell foam may be bonded to one or more outer layers, either continuously or with heat welding being used to create a quilted pattern, if desired.
In a tree-wrapping application,, the material may further include a pest-attracting and/or insect-capturing substance applied to the inside surface of the wrapping material, this substance being preferably exposed through the removal of a release layer.
Now turning to Figure 7A, there is shown a method of obtaining an image suitable for use on a sheet of material according to the invention, wherein a camera 702 is used to gather an image of a living plant 704, which is then converted to a form for printing purposes. It should be understood that the camera 702 may be of the film type, or may be electronic and all digital, depending upon the technology available. In taking a photograph of a bush, however, which has a modified cylindrical shape, the portion of the center of the bush represented by "C" in Figure 7A will have a flat appearance, whereas the two edges El and E2, will be compressed as the foliage follows its way around either side of the plant.
To correct for this apparent distortion, the aspect area shown in Figure 7B may be modified, such that the two side areas may be expanded so as to flatten them out in agreement with the area C. Having performed this image manipulation, once printed on to the material, and wrapped around the plant to be protected, a more life-like appearance should be realized. As a further alternative, one may image a large grouping of plants at a distance, for example, using a telephoto lens, which would create a substantially flat image which could be used without further modification or a plurality of images may be gathered from different angles, as shown in Figure 7C, and merged to produce an expanded image such as that depicted in Figure 7B.
This invention relates generally to protective coverings for plants, bushes, shrubbery, and so forth during harsh or cold weather, and, more particularly, to an improved, more aesthetic covering which is more conformal to the shape of the plant to be protected, and one which is more easily stored during periods of non-use.

Having performed this image manipulation, once printed on to the material, and wrapped around the plant to be protected, a more life-like appearance should be realized. As a further alternative, one may image a large grouping of plants at a distance, for example, using a telephoto lens, which would create a substantially flat image which could be used without further modification or a plurality of images may be gathered from different angles, as shown in Figure 7C, and merged to produce an expanded image such as that depicted in Figure 7B.
