DESCRIPTION OF THE PREFERRED EMBODIMENTS




The present invention contemplates a plant packaging system comprising a floral sleeve having a protective upper sleeve portion and a decorative lower cover portion for packaging a potted plant. The protective upper sleeve portion can be detached from the decorative lower cover portion of the floral sleeve once the protective function of the protective upper portion of the sleeve has been completed, thereby leaving the decorative lower cover portion in a position covering the pot. The protective upper sleeve portion and decorative lower cover portion may be of unitary construction or may consist of separate components which are attached together by various bonding materials or other sealing or attaching methods.




More specifically, the present invention contemplates a sleeve-type plant cover for covering a pot having a bottom surface and an outer peripheral surface. The plant cover comprises (1) a decorative lower cover portion having a lower end, an upper end, an outer peripheral surface, and an expansion element for allowing expansion of a portion of the decorative lower cover portion, and (2) a protective upper sleeve portion extending from the upper end of the decorative lower cover portion and detachable therefrom. As used herein, the term “expansion element” means an amount of material or, alternately, a type of material which can be expanded or unfolded to cover a greater area than in the unexpanded state. The expansion element may be an inwardly folded or outwardly folded gusset, a pleated or folded area, overlapping folds, or elastic material. When the pot is inserted into the decorative lower cover portion, the expansion element expands to allow the pot to fit into the decorative lower cover portion of the sleeve. The decorative lower cover portion of the sleeve is sized to substantially cover and conform to the outer peripheral and bottom surface of the pot once the decorative lower cover portion has been expanded about the pot.




In a preferred embodiment, the sleeve is constructed so that when the pot is disposed within the sleeve, the sleeve conforms to the shape of the pot so that the bottom of the pot is coplanar with the inner bottom surface of the sleeve wherein there are substantially no overlapping folded portions in that portion of the sleeve which is underneath the pot. Further, it is also preferred that the side wall of the sleeve in the erected position extends angularly from the bottom of the sleeve upwardly from the bottom. Preferably the side wall of the expanded sleeve extends upwardly from the bottom of the sleeve at a substantially uniform angle so that there are no outwardly extending “ears” such as those seen in U.S. Pat. No. 5,235,782 expressly incorporated herein by reference. More preferably, the side wall of the sleeve in the expanded condition extends upwardly from the bottom at substantially the same angle at which the side wall of the pot extends from the bottom of the pot. Preferably, the bottom of the sleeve in the expanded condition conforms to the curvature of the circumference of the bottom of the pot disposed therein. Also, preferably, the side wall of the sleeve in the expanded condition conforms to the curvature of the circumference of the outer peripheral surface of the pot or to the circumference taken through a plane thereof.




In a preferred embodiment, the sleeve is constructed such that when the sleeve is converted to the expanded position and a pot is disposed therein, both the bottom and the side walls of the sleeve fit closely against the bottom and sidewalls of the pot leaving substantially no void space or gaps there between. In an alternative preferred embodiment, if a gap does exist between the walls of the sleeve and the walls of the pot, the gap is substantially uniform for the entire length of the side wall of the sleeve from the bottom of the sleeve to the upper end of the pot in any given plane.




In a particularly preferred embodiment, the present invention comprises a flattened sleeve for containing a pot having an outer peripheral surface and a bottom surface. The sleeve comprises a first panel having an upper end, a lower end, a first side and a second side, a second panel having an upper end, a lower end, a first side and a second side, and a gusset portion. In this embodiment of the flattened sleeve, the first panel is disposed flatwise upon the second panel with the first side of the first panel joined with the first side of the second panel, and with the second side of the first panel joined with the second side of the second panel, and with the gusset portion extending from the lower end of the first panel and from the lower end of the second panel. The gusset is inwardly folded to extend a distance between the first panel and the second panel.




In this embodiment, the flattened sleeve has a convexly curved lower end, and when the sleeve is expanded to an open state and disposed about the pot, the sleeve has a side wall which substantially surrounds the outer peripheral surface of the pot and a bottom substantially without an overlapped portion therein when the pot rests upon the bottom of the sleeve. Preferably, the bottom of the sleeve in the open state substantially conforms to the circumferential curvature of the bottom surface of the pot. Also preferably, the side wall of the sleeve in the open state substantially conforms to the curvature of the outer peripheral surface of the pot. The side wall of the sleeve in the open state may extend upwardly from the bottom of the sleeve at an angle greater than 90 degrees when a pot is disposed within the sleeve. Also, the side wall of the sleeve in the open state may extend upwardly at a substantially uniform angle from the bottom of the sleeve along the outer peripheral surface of the pot disposed therein.




Preferably, the sleeve comprises an upper sleeve portion extending from the upper end of the first panel and from the upper end of the second panel and which is detachable therefrom via detaching means. Additionally, the sleeve forms a decorative cover when disposed about the pot. Further, the gusset in a preferred embodiment has a straight fold extending from the first sides of the first and second panels to the second sides of the first and second panels. Alteratively, the gusset has a curved fold extending from the first sides of the first and second panels to the second sides of the first and second panels. Moreover, a bonding material may be disposed upon a portion of the sleeve for connecting to the pot. The present invention may also comprise a package comprising a flower pot or other items described herein disposed within the sleeve described above, or any other sleeve described herein. The present invention may also comprise a method of assembling a package comprising a flower pot or other items described elsewhere herein disposed within the sleeve described above, or any other sleeve described herein.




In another embodiment, the flattened sleeve is defined as above with a first panel, second panel and gusset and is for containing a pot having a bottom surface with a characteristic geometric shape. In this embodiment, the sleeve is not defined as having a convexly curved lower end but rather as having, in the open state, a bottom having a shape which conforms to the characteristic geometric shape of the bottom surface of the pot so that the bottom of the sleeve is left substantially without an overlapped portion therein when the pot rests upon the bottom of the sleeve. Where used herein, the term “substantially without an overlapped portion” in the bottom of the sleeve means that the bottom has no single fold the length of which exceeds one radius of the diameter of the bottom surface of the pot or plurality of folds the total lengths of which exceed one diameter of the bottom surface of the pot.




The upper sleeve portion when present may be detachable via a detaching element or assembly such as perforations, tear strips and zippers. The plant cover may have an extended portion extending from the upper portion for serving as a handle or support device. Further, the expansion element is optionally constructed and positioned in the sleeve for allowing expansion of a portion of the lower portion into a decorative skirt extending angularly from the decorative lower portion when the upper sleeve portion is detached from the upper end of the lower portion. The expansion element may be inwardly or outwardly folded gussets, a plurality of vertical pleats, a plurality of vertical folds each having a z-shaped cross section, a plurality of vertical accordion-type folds, or other similar types of expandable forms. The expansion element may comprise a plurality of randomly positioned overlapping folds. Any of the folds described herein may be connected or unconnected. The expansion element may be an elastic material which expands to fit the outer surface and bottom surface of the pot when the pot is inserted into the lower portion. These embodiments are all described in further detail below.




The lower portion of the sleeve may be constructed from a first material and the upper sleeve portion may be constructed from a second material different from the first material; or a portion of the lower portion may be constructed from the same material as the upper sleeve portion; or the expansion element may be constructed of one material and the remainder of the lower portion and/or upper portion of the sleeve constructed of another material.




The tubular sleeve may form part of a plant package when used in conjunction with a pot disposed within the retaining space of the lower portion of the tubular sleeve, the pot having a floral grouping disposed therein, and wherein the pot is substantially surrounded and encompassed by the lower portion and the floral grouping is substantially surrounded and encompassed by the upper sleeve portion.




Further, the lower portion of the sleeve may have a bonding material disposed thereon for bondingly connecting the lower portion of the sleeve to the upper sleeve portion. Also, the lower portion may have a bonding material for bondingly connecting to a pot disposed therein. Further, the upper sleeve portion may have a bonding material for bondingly connecting to the lower portion. The plant cover may further comprise part of a plant package which includes a pot disposed within the inner retaining space of the lower portion of the sleeve, the pot having a floral grouping disposed therein, and wherein the pot is substantially surrounded and encompassed by the decorative lower portion of the sleeve and the floral grouping is substantially surrounded and encompassed by the upper sleeve portion.




The lower decorative portion of the tubular sleeve may be constructed from a first material and from a second material different from the first material.




While the various sleeve embodiments disclosed herein are primarily directed to use with round bottom flower pots, it will also be clear to one of ordinary skill in the art that one may construct sleeves using the technology described herein which are adapted to fit about and enclose pots having configurations other than round, such as square, rectangular, triangular, trapezoidal, cylindrical, ovoid and other well-known geometric shapes, and which function in accordance with the present invention to substantially conform to the shape of the pot. An example of such a sleeve is shown in FIGS. 20-23 in U.S. Pat. No. 5,493,809 issued Feb. 27, 1996, the specification and drawings of which are hereby specifically incorporated herein by reference in their entirety. Where a pot has a shape other than a curved shape, i.e., such as a square, the sleeve conforms to the perimeter of the pot, or to the perimeter of a plane therethrough.




The sleeve described herein can also be used in various embodiments as a growing container or flower pot for growing and cultivating various botanical items. The sleeve described herein may also be used as a combination growing pot and decorative cover for a botanical item, wherein the botanical item is first cultivated in the sleeve, then displayed in the decorative portion of the sleeve. The sleeve in its various embodiments described herein may also be used to contain various comestible items such as candy, treats, popcorn, french fries, chicken nuggets, and other fried items, and frozen confections. The sleeve may further be used to contain liquids for drinking or storage; the sleeve may be a collapsible cup, for example.

A preferred embodiment of the present invention, as shown in

FIGS. 1 and 2

and designated therein by the general reference numeral


10


, is a flexible tubular bag or sleeve. The sleeve


10


initially comprises a flexible flat collapsed piece of material which is openable in the form of the tubular bag or sleeve


10


. The sleeve


10


preferably is tapered so that in a flattened state, the sleeve


10


generally has an overall trapezoidal or modified trapezoidal shape, and when opened is substantially frusto-conical to coniform. It will be appreciated, however, that the sleeve


10


may comprise variations on the aforementioned shapes or may comprise significantly altered shapes such as square or rectangular, wherein the sleeve


10


when opened has a cylindrical or columnar form, as long as the sleeve


10


functions in accordance with the present invention in the manner described herein.




The flattened sleeve


10


has an upper end


12


, a lower end


14


, a first side


16


and a second side


18


. The sleeve


10


, which is tapered outwardly from the lower end


14


toward the upper end


12


so that the upper end


12


has a larger diameter than the lower end


14


, has an opening


19


in the upper end


12


and, in a preferred embodiment, is closed at the lower end


14


.




The sleeve


10


comprises a first panel


20


and a second panel


22


which lay flatwise upon each other and are longitudinally sealed, connected, or otherwise continuous along the first side


16


and the second side


18


. The sleeve


10


in its flattened, folded state further comprises a gusset


24


having a length


25


and which has a fold


26


extending between first and second sides


16


and


18


whereby the gusset


24


is inwardly folded between the first and second panels


20


and


22


. The inwardly folded gusset


24


comprises the expansion element in this embodiment. The fold


26


may be straight (i.e.,

FIGS. 1

or


5


A) or curved (FIG.


6


A). An outer edge


27


of the inwardly folded gusset


24


is continuous with the lower edge


28


of first panel


20


and with the lower edge


30


of second panel


22


thereby forming the closed and flattened lower end


14


of the sleeve


10


. The lower edge


28


and lower edge


30


of the first and second panels


20


and


22


are convexly curved and therefore cause the lower end


14


of the sleeve


10


to have a convexly curved configuration. The first panel


20


has an outer surface


34


and an inner surface


36


and the second panel


22


has an outer surface


38


and an inner surface


40


. The gusset


24


has an outer surface


44


, and an inner surface


45


. The inner surfaces


36


and


40


of the first and second panels


20


and


22


, together with the inner surface


45


of the gusset


24


, define the boundaries of an interior space


46


of the sleeve


10


. In another embodiment, the sleeve has a sealed rounded lower end with no gusset, such as that shown in FIGS. 43 and 44 in U.S. Pat. No. 5,493,809, the specification and drawings of which are hereby incorporated herein by reference in their entirety.




The construction of the lower end


14


of the sleeve


10


, comprising a rounded gusset


24


with a fold


26


, permits the circular bottom of an object such as a potted plant to be disposed within the interior space


46


and therein cause a lower portion of the sleeve


10


to conform closely to the frusto-conical shape of the pot as shown in

FIG. 3

as described in detail below. Briefly, the bottom of the pot rests upon at least a portion of the inner surface


45


of the gusset


24


, and the outer side walls of the pot rest closely against at least a portion of the inner surfaces


36


and


40


of the first and second panels


20


and


22


, respectively. Once expanded, the sleeve


10


has a side wall


48


and a bottom


49


for supporting the pot. The gusset


24


may be constructed from a separate material from the panels


20


and


22


or, as will be clear to one of ordinary skill in the art, the gusset


24


may be constructed from the same web used to form the first and second panels


20


and


22


by sealing, then folding portions thereof. An example of how the gusset


24


may be formed from a separate sheet of material different from the web used to form the first and second panels


20


and


22


is shown in U.S. Pat. 3,380,646, issued to Doyen in FIGS. 9 and 10 and discussion thereof, which is expressly incorporated herein by reference.




As shown in

FIG. 1

, the sleeve


10


is demarcated into an upper protective portion


50


and a lower decorative portion


52


. The lower decorative portion


52


of the sleeve


10


is sized to contain a pot of a size standard in the floral industry and well known to persons of ordinary skill in the art. The upper protective portion


50


of the sleeve


10


is sized to substantially surround and encompass a floral grouping disposed in the pot. The sleeve is demarcated into the upper protective portion


50


and the lower decorative portion


52


by a detaching element


54


for enabling the detachment of the upper protective portion


50


of the sleeve


10


from the lower decorative portion


52


of the sleeve


10


. In the preferred version, the detaching element


54


is a plurality of perforations in a crenulated or wavy pattern which extends circumferentially across the first panel


20


and second panel


22


of the sleeve


10


from the first side


16


to the second side


18


. The term “detaching element”, as used generally herein, means any element, or combination of elements or features, such as, but not by way of limitation, perforations, tear strips, zippers, and any other devices or elements of this nature known in the art, or any combination thereof, which enable the tearing away or detachment of one object from another. Therefore, while perforations are shown and described in detail herein, it will be understood that tear strips, zippers, or any other “detaching elements” known in the art, or any combination thereof, could be substituted therefore and/or used therewith.




In a preferred embodiment, as shown in

FIG. 1

, the lower decorative portion


52


of the sleeve


10


further comprises a base portion


56


, and a skirt or fringe portion


58


. The base portion


56


comprises that part of the lower decorative portion


52


which, when a pot is placed into the lower decorative portion


52


, has an inner peripheral surface which is substantially adjacent to and surrounds the outer peripheral surface of the pot. The skirt or fringe portion


58


comprises that part of the lower decorative portion


52


which extends beyond an upper rim of the pot and adjacent at least a portion of a floral grouping contained within the pot and which is left to freely extend at an angle, inwardly or outwardly or upwardly, from the base portion


56


when the upper protective portion


50


of the sleeve


10


is detached from the lower decorative portion


52


of the sleeve


10


by actuation of the detaching element


54


. In the intact sleeve


10


, the skirt portion


58


comprises an upper peripheral edge


59


congruent with the detaching element


54


which is connected to a lower peripheral edge


60


, also congruent with the detaching element


54


, of the upper protective portion


50


of the sleeve


10


. In

FIG. 1

, the upper peripheral edge


59


of the skirt portion


58


is congruent with a series of curved lines of perforations


61


which together form an undulating line and comprise the detaching element


54


.




The upper protective portion


50


of the sleeve


10


may optionally have an additional detaching element


62


indicated as a plurality of vertical perforations


63


for facilitating removal of the upper protective portion


50


and which are disposed more or less vertically therein extending between the perforations


61


of the detaching element


54


and the upper end


12


of the sleeve


10


. The upper protective portion


50


of the sleeve


10


is separable from the lower decorative portion


52


of the sleeve


10


by tearing the upper protective portion


50


along both the vertical perforations


63


of the detaching element


62


and the perforations


61


of the detaching element


54


, thereby separating the upper protective portion


50


from the lower decorative portion


52


of the sleeve


10


. The lower decorative portion


52


of the sleeve


10


remains disposed as the base portion


56


about the pot and as the skirt portion


58


about the floral grouping, forming a decorative cover


64


as shown in

FIG. 4

which substantially surrounds and encompasses the pot and a lower portion of the floral grouping therein. The upper protective portion


50


may have apertures


65


near the upper end


12


thereof so the sleeve


10


may be supported on a wicket (not shown).




As noted above, it will generally be desired to use the sleeve


10


as a covering for a plant or floral grouping contained within a pot


70


, as shown in FIG.


3


. The pot


70


has an upper end


72


, a lower end


74


, an outer peripheral surface


76


, a bottom surface


78


and an inner peripheral surface


80


which encompasses an inner space


82


for retaining a floral grouping or plant


84


. The lower end


74


of the pot


70


is generally closed but may have holes for permitting water drainage. The term “pot” as used herein refers to any type of container used for holding a floral grouping or plant


84


. Examples of pots, used in accordance with the present invention include, but not by way of limitation, clay pots, wooden pots, plastic pots, pots made from natural and/or synthetic fibers, or any combination thereof. The pot


70


is adapted to receive the floral grouping


84


in the inner space


82


. The floral grouping


84


may be disposed within the pot


70


along with a suitable growing medium described in further detail below, or other retaining medium, such as a floral foam. It will also be understood that the floral grouping


84


, and any appropriate growing medium or other retaining medium, may be disposed in the sleeve


10


without the pot


70


.




The sleeve


10


is generally frusto-conically shaped, but the sleeve


10


may be, by way of example but not by way of limitation, cylindrical, frusto-conical, a combination of both frusto-conical and cylindrical, or square or rectangular in cross-section, or any other shape, including geometric, non-geometric, asymmetrical and/or fanciful as long as it functions in accordance with the present invention described herein. The sleeve


10


may also be equipped with drains or ventilation holes (not shown), or can be made from permeable or impermeable materials.




The material from which the sleeve


10


is constructed has a thickness in a range from about 0.1 mil to about 30 mils. Often, the thickness of the sleeve


10


is in a range from about 0.5 mil to about 10 mils. Preferably, the sleeve


10


has a thickness in a range from about 1.0 mil to about 5 mils. More preferably, the sleeve


10


is constructed from a material which is flexible, semi-rigid, rigid, or any combination thereof. The sleeve


10


may be constructed of a single layer of material or a plurality of layers of the same or different types of materials. Any thickness of the material may be utilized as long as the material functions in accordance with the present invention as described herein. The layers of material comprising the sleeve


10


may be connected together or laminated or may be separate layers. Such materials used to construct the sleeve


10


are described in U.S. Pat. No. 5,111,637 entitled “Method For Wrapping A Floral Grouping” issued to Weder et al., on May 12, 1992, the specification of which is hereby expressly incorporated herein by reference in its entirety. Any thickness of material may be utilized in accordance with the present invention as long as the sleeve


10


may be formed as described herein, and as long as the formed sleeve


10


may contain at least a portion of the pot


70


or plant


84


, as described herein. Additionally, an insulating material such as bubble film, preferable as one of two or more layers, can be utilized in order to provide additional protection for the item, such as the floral grouping, contained therein.




In one embodiment, the sleeve


10


may be constructed from two polypropylene films. The material comprising the sleeve


10


may be connected together or laminated or may be separate layers. In an alternative embodiment, the sleeve


10


may be constructed from only one of the polypropylene films.




The sleeve


10


may also be constructed, in whole or in part, from a cling material. “Cling Wrap or Material” when used herein means any material which is capable of connecting to the sleeve


10


upon contacting engagement during the wrapping process and is wrappable about an item whereby portions of the cling material contactingly engage and connect to other portions of another material, or, alternatively, itself, for generally securing the sleeve


10


wrapped about at least a portion of the pot


70


. This connecting engagement is preferably temporary in that the material may be easily removed, i.e., the cling material “clings” to the pot


70


.




The cling material is constructed and treated if necessary, from polyethylene such as Cling Wrap made by Glad®, First Brands Corporation, Danbury, Conn. The thickness of the cling material will, in part, depend upon the size of sleeve


10


and the size of the pot


70


in the sleeve


10


, i.e., generally, a larger pot


70


may require a thicker and therefore stronger cling material. The cling material will range in thickness of from about 0.1 mil to about 10 mils, and preferably from about 0.5 mil to about 2.5 mils and most preferably from about 0.6 mil to about 2 mils. However, any thickness of cling material may be utilized in accordance with the present invention which permits the cling material to function as described herein.




The sleeve


10


is constructed from any suitable material that is capable of being formed into the sleeve


10


and wrapped about the pot


70


and the floral grouping


84


disposed therein. Preferably, the material is paper (untreated or treated in any manner), metal foil, polymeric film, non-polymeric film, fabric (woven or nonwoven or synthetic or natural), cardboard, fiber, cloth, burlap, or laminations or combinations thereof.




The term “polymeric film” means a synthetic polymer such as a polypropylene or a naturally occurring polymer such as cellophane. A polymeric film is relatively strong and not as subject to tearing (substantially non-tearable), as might be the case with paper or foil.




The material from which the sleeve


10


is made may vary in color and may consist of designs or decorative patterns which are printed, etched, and/or embossed thereon using inks or other printing materials. An example of an ink which may be applied to the surface of the material is described in U.S. Pat. No. 5,147,706 entitled “Water Based Ink On Foil And/Or Synthetic Organic Polymer” issued to Kingman on Sep. 15, 1992, and which is hereby expressly incorporated herein by reference.




In addition, the material may have various colorings, coatings, flocking and/or metallic finishes, or other decorative surface ornamentation applied separately or simultaneously or may be characterized totally or partially by pearlescent, translucent, transparent, iridescent, neon, or the like, qualities. Each of the above-named characteristics may occur alone or in combination and may be applied to the upper and/or lower surface of the material used to make the sleeve


10


. Moreover, portions of the material used in constructing the sleeve


10


may vary in the combination of such characteristics. The material utilized for the sleeve


10


itself may be opaque, translucent, transparent, or partially clear or tinted transparent.




The term “floral grouping” as used herein means cut fresh flowers, artificial flowers, a single flower or other fresh and/or artificial plants or other floral materials and may include other secondary plants and/or ornamentation or artificial or natural materials which add to the aesthetics of the overall floral grouping. The floral grouping generally comprises a bloom or foliage portion and a stem portion. Preferably, the floral grouping comprises a growing potted plant having a root portion (not shown) as well. However, it will be appreciated that the floral grouping may consist of only a single bloom or only foliage, or a botanical item (not shown), or a propagule (not shown). The term “floral grouping” may be used interchangeably herein with both the terms “floral arrangement” and “potted plant”. The term “floral grouping” may also be used interchangeably herein with the terms “botanical item” and/or “propagule.”




The term “growing medium” when used herein means any liquid, solid or gaseous material used for plant growth or for the cultivation of propagules, including organic and inorganic materials such as soil, humus, perlite, vermiculite, sand, water, and including the nutrients, fertilizers or hormones or combinations thereof required by the plants or propagules for growth.




The term “botanical item” when used herein means a natural or artificial herbaceous or woody plant, taken singly or in combination. The term “botanical item” also means any portion or portions of natural or artificial herbaceous or woody plants including stems, leaves, flowers, blossoms, buds, blooms, cones, or roots, taken singly or in combination, or in groupings of such portions such as bouquet or floral grouping.




The term “propagule” when used herein means any structure capable of being propagated or acting as an agent of reproduction including seeds, shoots, stems, runners, tubers, plants, leaves, roots or spores.




Further, in accordance with the present invention, a bonding material may be disposed on a portion of the sleeve


10


to assist in holding the sleeve


10


to the pot


70


having the floral grouping


84


therein when such a pot


70


is disposed within the sleeve


10


or to assist in closing the upper end


12


of the sleeve


10


or adhering the sleeve


10


to the pot


70


after the pot


70


has been disposed therein, as will be discussed in further detail below.




Preferably the bonding material


85


, when present, is disposed as a strip or block on the inner surface


36


and/or


40


of the sleeve


10


. The bonding material may also be disposed upon either or both of the outer peripheral surface


34


or


38


of the sleeve


10


, as well as upon the pot


70


. Further, the bonding material


85


may be disposed as spots, or in any other geometric, non-geometric, asymmetric, or fanciful form, and in any pattern including covering either the entire inner surfaces


36


and


40


of the sleeve


10


and/or outer peripheral surfaces


34


and


38


of the sleeve


10


and/or the pot


70


, or the entire inner surfaces


36


and


40


and/or the outer peripheral surfaces


34


and


38


of the sleeve


10


which constitute the base portion


56


of the lower decorative portion


52


of the sleeve


10


. The bonding material


85


may be covered by a cover or release strip which can be removed prior to the use of the sleeve, pot or pot cover. The bonding material


85


can be applied by means known to those of ordinary skill in their art. One method for disposing the bonding material


85


, in this case an adhesive, is described in U.S. Pat. No. 5,111,637 entitled “Method For Wrapping A Floral Grouping” issued to Weder et al., on May 12, 1992, which has been expressly incorporated herein by reference above.




The term “bonding material” when used herein means an adhesive, frequently a pressure sensitive adhesive, or a cohesive. When the bonding material is a cohesive, a similar cohesive material must be placed on the adjacent surface for bondingly contacting and bondingly engaging with the cohesive material. The term “bonding material” also includes materials which are heat sealable and, in this instance, the adjacent portions of the material must be brought into contact and then heat must be applied to effect the seal. The term “bonding material” also includes materials which are sonic sealable and vibratory sealable. The term “bonding material” when used herein also means a heat sealing lacquer or hot melt material which may be applied to the material and, in this instance, heat, sound waves, or vibrations, also must be applied to effect the sealing.




Alternatively, a cold seal adhesive may be utilized as the bonding material. The cold seal adhesive adheres only to a similar substrate, acting similarly as a cohesive, and binds only to itself. The cold seal adhesive, since it bonds only to a similar substrate, does not cause a residue to build up on equipment, thereby both permitting much more rapid disposition and use of such equipment to form articles and reducing labor costs. Further, since no heat is required to effect the seal, the dwell time, that is, the time for the sheet of material to form and retain the shape of an article, such as a flower pot cover or flower pot, is reduced. A cold seal adhesive binds quickly and easily with minimal pressure, and such a seal is not readily releasable. This characteristic is different from, for example, a pressure sensitive adhesive.




The fold


26


in the gusset


24


may be straight from side


16


to side


18


, as shown in

FIG. 5A

, or the fold


26


may be curved upwardly as explained below with reference to FIG.


6


A. When the fold


26


is straight, and when the pot


70


is inserted into the sleeve


10


, the pot


70


which is sized to optimally fit therein has a bottom diameter


86


. Bottom diameter


86


of the pot


70


preferably is in a range of from about 0.5x to about 0.75x where “x” is the length


25


of the gusset


24


.




When the pot


70


is deposited into the sleeve


10


having the straight fold


26


, a portion


88


of the gusset


24


(

FIG. 5A

) is positioned against the bottom surface


78


of the pot


70


to form part of the bottom


49


of the sleeve


10


. Additionally a portion


90


of the first panel


20




10


forms another portion of the bottom


49


of the sleeve


10


. Also, a portion


92


of second panel


22


, which is a mirror image of portion


90


of the first panel


20


, forms another portion of the bottom


49


. Together, portion


88


of the gusset


24


and portions,


90


and


92


of the first and second panels


20


and


22


form the bottom


49


of the sleeve


10


in the expanded state as shown in

FIGS. 5B and 5C

. Preferably, the bottom


49


of the open sleeve conforms to the curvature of the circumference of the bottom


78


of the pot


70


substantially as shown in FIG.


5


C.




Further, when the pot


70


having the bottom diameter


86


is inserted into the sleeve


10


, two mirror image side portions


94


and


96


of the gusset


24


(

FIG. 5A

) become part of the side wall


48


of the expanded sleeve


10


, as shown in

FIGS. 5B and 5C

. Thus, it can be seen then that in a preferred embodiment, the gusset


24


of the sleeve


10


in the flattened state surprisingly does not solely constitute the bottom


49


of the sleeve


10


in its expanded state. Rather, the bottom


49


of the sleeve


10


is constituted of portions


90


and


92


of the first and second panels


20


and


22


, and of portion


88


of the gusset


24


. Additionally, the side wall


48


of sleeve in its expanded state is constituted of side portions


94


and


96


of the gusset


24


, as well as of portions of the first and second panels


20


and


22


. The side wall


48


conforms to the curvature and shape of the pot


70


disposed within the sleeve


10


.




Alternatively, a sleeve


10




a


may be provided with a gusset


24




a


having a curved fold


26




a


as shown in FIG.


6


A. Fold


26




a


extends further inwardly between first and second panels


20




a


and


22




a


toward the upper end


12




a


of the sleeve


10




a


than does the fold


26


in the sleeve


10


shown in FIG.


5


A. When the pot


70




a


having a bottom diameter


86


is deposited into the sleeve


10




a


having the curved fold


26




a


, a circular portion


100


of the gusset


24




a


is positioned against the bottom surface


78


of the pot


70




a


and forms a bottom


49




a


for the sleeve


10




a


which conforms to the curvature of the bottom surface


78


of the pot


70




a


(FIG.


4


). Additionally, two mirror image side portions


102


and


104


of the gusset


24




a


become part of a side wall


48




a


of the sleeve


10




a


when the sleeve


10




a


is in an expanded state, as shown in

FIGS. 6B and 6C

. It can be seen then that when the gusset


24




a


has the curved fold


26




a


in the flattened state, the portion


100


of the gusset


24




a


comprises substantially the entire bottom


49




a


of the sleeve


10




a


when expanded and that the side wall


48




a


of the sleeve


10




a


is formed both from the first and second panels


20




a


and


22




a


, and from portions


102


and


104


of the gusset


24




a


. It will also be understood by one of ordinary skill in the art that the fold in the gusset


24


may be intermediate in curvature between the straight fold


26


and the curved fold


26




a


(or even may be convex rather than concave) and therein may possess properties of the straight fold


26


but to a lesser degree. Any of the sleeves described anywhere herein which comprise a gusset may have a gusset having a straight fold, or a fold which is curved.

10




e


. The support extension


118


has one or more apertures


120


disposed therein for allowing the sleeve


10




e


to be supported on a support assembly which is commercially available and known by one of ordinary skill in the art such as a pair of wickets for shipment, storage, assembly of the sleeve


10




e

for removing the handle


124


from the sleeve


10




f


at a later time.




The sleeves described herein may be formed by intermittently advancing two separate webs, one or two webs preformed in the form of a tube, or a single web folded double and sealing the longitudinal sides and bottom of the two facing panels then cutting the sleeve thus formed from the webs or web. Machines which can form sleeves from such single webs or pairs of webs are well within the knowledge of one of ordinary skill in the art.




As shown in

FIG. 1

, the detaching element


54


is preferably the line of perforations


61


having a regular or irregular curved or wavy pattern extending from side


16


to side


18


on both the first panel


20


and second panel


22


. It will be understood that the line of perforations


61


of the detaching element


54


of the sleeve


10


in the sleeve


10


(or in any of the other sleeves described herein) may be constructed in any number of other decorative patterns, several being shown in

FIGS. 12-16

. For example,

FIG. 12

shows the line of perforations


61


as having a crenate or scalloped pattern which is inverted.

FIG. 13

shows the line of perforations


61


of the detaching element


54


of the sleeve


10


as having a crenate or scalloped pattern which is inverted.

FIG. 14

shows the line of perforations


61


of the detaching element

FIG. 16

shows the line of perforations


61


of the detaching element


54


of sleeve


10


having a diagonal pattern slanted upwardly from one side of the sleeve to the other. One of ordinary skill in the art will understand these are but a few of the patterns that the perforations may form and one of ordinary skill could contemplate many other suitable patterns.




In another embodiment, the sleeve designated in

FIG. 17

as sleeve or flat cover


130


(hereinafter referred to as flat cover


130


) is formed exactly as any of the versions of the sleeves described herein except that it is formed without an upper protective sleeve portion. In this version the sleeve serves as a decorative cover and may be formed with or without a decorative skirt portion or decorative border which extends from or comprises an upper edge


131


of the flat cover


130


.




The flat cover


130


has an upper end


132


, a lower end


134


, a first side


136


, and a second side


138


. The flat cover


130


has an opening


139


at the upper end


132


and is closed at the lower end


134


. The flat cover


130


comprises a first panel


140


and a second panel


142


which lay substantially flatwise upon each other and are longitudinally sealed, connected or otherwise continuous along first side


136


and second side


138


. The flat cover


130


further comprises a rounded gusset


144


having a length


145


and which has a fold


146


extending between sides


136


and


138


whereby the rounded gusset


144


is inwardly folded between the first and second panels


140


and


142


. The inwardly folded rounded gusset


144


comprises the expansion element in this embodiment. The fold


146


may be straight or curved as described above for sleeve


10


in

FIGS. 5A and 6A

and functions in a similar manner. As shown here, the flat cover


130


has essentially the same construction as sleeve


10


, or any other sleeves shown elsewhere herein, except it is not formed with a detachable upper protective sleeve portion. As for the sleeve


10


, the construction of the lower end


134


of the flat cover


130


comprising the rounded gusset


144


with the fold


146


permits the circular bottom of an object such as a potted plant to be disposed therein causing the lower portion of the flat cover


130


to conform closely to the frusto conical shape of the pot


10


as shown in FIG.


4


and described in detail elsewhere herein.




The flat cover


130


, thus formed, may be equipped with or absent of apertures


148


near the upper end


132


for enabling the flat cover


130


to be placed on a wicket for transport and ease of handling. The flat cover


130


may further be constructed with an upper end


132


having an upper edge


131


or border having any of the shapes of the perforation


61


of the detaching element


54


described elsewhere herein, for example, in

FIGS. 12-16

.




Another embodiment of a sleeve constructed in accordance with the present invention is shown in

FIGS. 18-19

and designated herein by the reference numeral


150


. Sleeve


150


is exactly the same as sleeve


10


or any of the other gussetted sleeves described herein except that sleeve


150


comprises a gusset


152


which is outwardly folded back upon an outer surface


154


of the sleeve


150


rather than inwardly folded as in sleeve


10


.




Embodiments and Methods of Use of FIGS.


20


-


34






Attention is now drawn to the versions of the present invention which are shown in

FIGS. 20-34

and more specifically to the sleeve in

FIG. 20

which is designated therein by the reference numeral


160


, and which is the same as the sleeves described elsewhere herein except for the differences described below. The sleeve


160


, comprises a unitary construction and has a lower decorative portion


162


, an optional skirt portion (not shown herein but which is described in U.S. Pat. No. 5,625,979 issued May 6, 1997, the specification of which is hereby expressly incorporated herein by reference in its entirety), an upper protective sleeve portion


164


and a plurality of pleats


165


comprising expansion elements


166


(only a few of which are specifically designated as such in

FIG. 20

) and further has an outer peripheral surface


168


, an open upper end


170


and a closed lower end


172


which in

FIG. 20

is rounded. The sleeve


160


, like the sleeves discussed elsewhere herein, has an inner retaining space


174


which extends from the open upper end


170


to the lower end


172


and which is bounded by an inner peripheral surface


176


of the sleeve


160


. The lower decorative portion


162


is sized to substantially cover an outer peripheral surface of a pot, such as the outer peripheral surface


76


of the pot


70


as described elsewhere herein; and the upper protective sleeve portion


164


is sized to substantially surround a floral grouping in a pot which is disposed within the inner retaining space


174


of the sleeve


160


similar to the floral grouping


84


disposed in the pot


70


as hereinbefore described with reference to FIG.


4


.




The upper protective sleeve portion


164


is detachable from the lower decorative portion


162


of the sleeve


160


via a detaching element


178


such as the line of perforations


61


of the detaching element


54


described in detail in regard to sleeve


10


above. The expansion elements

Shown in FIG.


35


and referred to there by reference numeral


200


is another version of a sleeve constructed in accordance with the present invention. The sleeve


200


and versions thereof are the same in all respects to the various embodiments of the sleeves described elsewhere herein except an expansion element


201


comprises an elastomeric lower portion


202


. The lower portion


202


of the sleeve


200


is constructed of material having elastomeric properties which allows the elastomeric lower portion


202


to expand when a pot is disposed within the sleeve


200


and when the elastomeric lower portion


202


of the sleeve


200


is stretched about a lower portion of a pot. The elastomeric lower portion


202


may be fabricated of lycra, rubber, elasticized fabrics, or any other sheet materials which have elastic properties. The elastomeric lower portion


202


of the sleeve


200


will grip an adjacent portion of a pot and will cause the elastomeric lower portion


202


of the sleeve


200


to closely conform to the shape of the pot and will secure the sleeve


200


to the pot leaving substantially no void space as explained above. The sleeve


200


preferably has an upper portion


204


constructed from the same material as non-elastomeric sleeves described herein above.




The lower elastomeric portion


202


may be a separate component connected to a lower end


205


of the upper portion


204


of the sleeve


200


. Alternatively, the lower elastomeric portion


202


may be of unitary construction with the upper portion


204


of the sleeve


200


which is non-elastomeric. The lower elastomeric portion


202


may be an elasticized or rubberized extension of the upper portion


204


. For example, the sleeve


200


may be constructed from a fabric which is impregnated with an elastic material in one portion to form the elastomeric lower portion


202


.




Shown in

FIGS. 36

in

FIGS. 26-29

, respectively, that is, without an upper sleeve portion. In another series of versions the present invention contemplates sleeves having expansion elements similar to those of

FIGS. 20-34

and which also have elastomeric properties.




The elastomeric portion of the sleeve


200


may comprise most or all of the lower elastomeric portions

d


as shown in

FIG. 39

; or the elastomeric portion may comprise only a gusset portion


206


as shown on sleeve


200




e


in FIG.


40


.




It will be understood that the elastomeric lower portion, when expanded about a pot may cover only a bottom surface of the pot, or may cover the bottom surface of the pot and a portion of an outer peripheral surface of the pot above the bottom of the pot. In yet another version of the elastomeric sleeve, the elastomeric portion of the sleeve may be constructed in such a way that the bottom of the pot disposed within the sleeve may be covered by a non-elastomeric portion of the sleeve, while a portion of the outer peripheral surface of the pot is the portion surrounded by the elastomeric portion of the sleeve. The elastomeric portion of the sleeve functions to eliminate or minimize the void space between the inner surface of the sleeve and the outer surface or bottom of the pot. Finally, the the entire sleeve may be fabricated of an elastomeric material, as shown in sleeve

Sleeves with overlapping folds are shown as having the same lower end configuration as sleeves described above herein, for example, the sleeves of

FIGS. 20-23

, respectively.




The sleeves having overlapping folds may be constructed in any of the manners and configurations shown elsewhere herein.




For example, each of the sleeves


210


-


210




f


may further comprise a support extension as mentioned previously which extends away from a portion of the upper end of the sleeve such as for the sleeve


10




e


as shown in FIG.


10


. As described earlier the support extension has one or more apertures disposed therein for allowing the sleeve to be supported on a support assembly which may comprise, for example, a pair of wickets for shipment, storage, assembly of the sleeve, placement of a pot within the sleeve, or other functions known in the art. As noted above, the support extension may have a plurality of perforations or other detaching means for allowing the support extension to be removed from the sleeve after the sleeve has been provided for use as described elsewhere herein. In another version of the invention, and applicable to any of the sleeves described above, or elsewhere herein, a sleeve has a handle for carrying the potted plant package by the sleeve. The sleeve further comprises a detaching element comprising perforations for removing the handle at a later time.




As noted above, the protective sleeve and decorative cover components of the present invention may comprise a unitary construction. Or, may comprise separately formed components which are attached or sealed together by various bonding materials, as shown and described elsewhere herein.




In yet another version of the invention, a sleeve designated by the general reference numeral


220


is shown in FIG.


49


. Sleeve


220


is exactly the same as sleeve


10


or any of the various versions and embodiments described or shown in Figures. elsewhere herein except sleeve


220


further comprises a plurality of slits


222


disposed in a lower portion


224


thereof for enabling the lower portion


224


to be more easily expanded to fit snugly about an outer peripheral surface of a pot disposed therein.




Referring now to the embodiments of

FIGS. 50-56

, shown therein are several alternative shapes of the lower ends of sleeves which may be constructed in accordance with the present invention. Shown in

FIGS. 50-56

are sleeves designated with the general reference numerals


230


,


232


,


234


,


236


,


238


,


240


and


242


, respectively. Each of sleeves


230


-


242


has a non-gussetted lower end which is sealed closed in a manner similar to either of the sleeves shown in

FIGS. 21

or


23


and are ideally suited to any of the sleeves described herein having expansion elements, for example, such as pleats, overlapping folds, slits, and elastomeric portions. The lower ends may have a partially rounded shape (FIG.


50


), an outwardly-directed partially trapezoidal shape (FIG.


51


), an expanded rounded or bulbous shape (FIG.


52


), a curved pointed shape (FIG.


53


), a triangular shape (FIG.


54


), an inwardly-directed trapezoidal shape (FIG.

In another version of the invention, shown in

FIGS. 57 and 58

, a sleeve designated by the general reference numeral


244


, is constructed exactly the same as the sleeves discussed elsewhere herein except that the sleeve


244


has an open lower end


246


and a strap or band


248


which extends across the open lower end


246


. The band


248


functions to prevent the sleeve


244


from “riding up” on a pot disposed within the sleeve


244


, or to prevent the pot from dropping through the open lower end


246


of the sleeve


244


.




Construction of the Sleeves—FIGS.


59


-


60






It will be readily appreciated by those of ordinary skill in the art that processes for making standard floral sleeves which have open upper and lower ends are well known. In the preferred embodiment of the present invention, the sleeve is constructed with a closed bottom which may simply comprise a seal along the lower end of the sleeve or more preferably the closed bottom comprises an infolded portion such as a gusset which when opened enables expansion of the bottom of the sleeve for allowing insertion of a pot therein and a close, conforming fit thereto.




One version of an apparatus and process used to construct a sleeve such as sleeve


10


described herein is shown in

FIG. 59. A

single web of material


250


from a roll


251


is fed by a drive mechanism such as an electric motor (not shown) to a folding assembly


252


which causes the web


250


to fold and double up on itself to form a folded web


254


having an open side


256


and a folded side


258


. The folded web


254


is supported upon a conveyor or other support surface


260


. As the folded web


254


is advanced by drive rollers


261


or other advancing mechanism in direction


262


, the folded side


258


is caused in a continuous process to be infolded or pouched by an infolding device


264


forming a pouch


266


which extends the length of the web


254


therefrom. The web


254


with the pouch


266


therein continues to be advanced in direction


262


to a sealing position


268


. A sealing bar (not shown), such as is common and well known in the art, is then activated forming a pair of longitudinally sealed edges


269


and


270


. The sealed edges


269


and


270


extend from near the pouch


266


to the open side


256


and may extend completely about the lower end of the incipient sleeve if a gusset is not formed therein.




In the embodiment of the sleeve formed using the apparatus of

FIG. 59

, not only is the lower end formed with a rounded bottom, but a gusset is also formed. The gusset is formed when portions of the infolded folded pouch


266


of the web


254


are sealed by a sealing device such as the double sealing mechanism


271


shown in

FIGS. 59 and 60

. The sealing mechanism


271


is comprised of an upper sealing portion


272


and a lower sealing portion


274


. The upper sealing portion moves in a direction


276


and presses an infolded portion of the web


254


against the upper side


278


of the infolding device


264


and seals a portion


280


of the web


254


by heating, pressure or other sealing means well known to those of ordinary skill in the art. Similarly the lower sealing portion


274


moves in a direction


282


and presses an infolded portion of the web


254


against the lower side


284


of the infolding device


264


and seals a portion


286


of the web


254


as above. In this manner a rounded gusset


288


is formed.




The web


254


, now having a sleeve outlined by the sealed edges


269


and


270


and with a gusset


288


, is further advanced to a perforating position


290


where perforations


291


are punched into the sleeve and optionally support apertures are also punched into the sleeve for enabling a collection of sleeves to be collected in a stack and held on a support mechanism such as a wicket. Ventilation holes may also be punched into the sleeve at this point. In the next step the sleeve, now with sealed edges


269


and


270


, gusset


288


, and perforations


291


, is advanced to a cutting position


292


where the sleeve is cut by a cutting die or blade (not shown), such as is well known in the art, from the web


254


to form a complete sleeve


294


. Excess material


296


may be removed to facilitate removal and storage of the sleeve


294


. It will be understood by one of ordinary skill in the art that the steps of sealing, perforating and cutting the sleeves may be performed together in a single step, or two steps at one or two positions.




The process outlined above describes the construction of a sleeve


294


similar to a sleeve


10


without a bonding material disposed upon any portion thereof. However, as explained above, in an alternative version of the invention, a bonding material for bonding a portion of the sleeve to a pot is located on a portion of the inner surface of the sleeve. Shown in

FIG. 59

is a bonding material applicator


298


such as a sprayer or pad applicator which can be used to apply an area of bonding material


300


to a portion of the inner surface of the sleeve


294


. The bonding material applicator


298


may be reciprocatingly activated by a reciprocating assembly (not shown) which is preferably automatically controlled and construction of which is well within the level of ordinary skill in the art. The bonding material


300


is preferably applied to the web


250


prior to the doubling over of the web


250


so that when the web


250


is doubled over to form the folded web


254


, the bonding material


300


is oriented on a portion of the inner surface of the sleeve


294


preferably in the lower portion of the sleeve


294


. The result is the production of a sleeve such as one of those shown in

FIGS. 7-9

.




The process described herein can be modified to produce sleeves such as any of the other sleeves described elsewhere herein. For example, a sleeve can be produced by inserting a piece of release material (not shown) into the sleeve


294


at some point during the sleeve production process, either manually or automatically, for example, after the bonding material


300


has been applied but before the web


250


has been folded over to form the folded web


254


. The piece of release material may be inserted manually by hand or automatically using a device which automatically shoots or blows or deposits such pieces of material and which is well within the skill of one of ordinary skill in the art. Alternatively, the release material may be applied directly upon the bonding material


300


when the bonding material


300


is applied to the web


250


. An additional area of bonding material may be applied to another portion of the web with another adhesive applicator (not shown) thereby forming sleeves having bonding material


300


distributed on different portions of the sleeve.





FIG. 59

shows both edges of open side


256


of the web


254


as being an equal distance from the folded side


258


. It will be understood by one of ordinary skill in the art that the two edges which comprise the open side


256


of the web


254


can be offset during the folding process to form a sleeve such as a sleeve shown in

FIGS. 8

,


10


, or


11


having an upper end flap which can be folded over to close the upper end or an upper portion used to form an extension of the sleeve.





FIG. 59

shows a sleeve-forming process in which a single web is doubled over to form the double-layered web. The sleeve formed as described herein may also be formed during a process using two or more separate webs in a manner well-known in the art. A first roll of material and a second roll of material provide a first web of material and a second web of material, respectively. These webs are fed to a position where one side of the two webs are sealed by a sealing assembly. If a gusset in the finished sleeve is desired, the sealed side can be infolded to form a pouched side as described in the process of FIG.


59


. The remainder of the operation can be formed as described above for the process of FIG.


59


.




Sleeves formed in accordance with the present invention can also be formed from tubular materials such as are commercially available. For example, a sleeve can be formed by cutting a portion of a tube, forming a gusset in the lower end of the tube, or sealing the lower end of the tube to form a closed bottom, then sealing and cutting off portions of the lower end of the tube forming a sleeve having a tapered lower end. Adhesive may be applied to an interior portion of the sleeve by opening the tube and spraying a bonding material onto a portion of the inner surface of the sleeve, for example. In another version of the invention, the process of forming the tubular material from one or more flat webs of material may comprise a step in the process of forming a sleeve.




Changes may be made in the construction and the operation of the various components, elements and assemblies described herein or in the steps or the sequence of steps of the methods described herein without departing from the spirit and scope of the invention as defined in the following claims.
