This invention generally relates to sleeves to be used as containers and, more particularly, sleeves used to wrap flower pots containing floral groupings and/or media containing floral groupings, and methods of using same.
It is well known in the floral packaging industry to apply floral sleeves about potted plants for the purpose of erecting a protective sheath about the blooms and foliage of the potted plant for preventing damage to them and entanglement with adjacent plants. Such sleeves generally have an open bottom through which the inserted pot is exposed. U.S. Pat. No. 4,333,267 issued to Witte and U.S. Pat. No. 4,413,725 issued to Bruno, and Australian Patent 42319/78 show examples of such open-bottom sleeves.
Other sleeves have closed bottoms upon which the bottom of the pot can rest. However, in such closed sleeves, the lower portion does not have a shape which conforms to the shape of the bottom and outer sides of the pot. For example, in U.S. Pat. No. 5,235,782 issued to Landau, an unattractive void space is formed about the pot when the pot is inserted into the sleeve. In U.S. Pat. No. 5,388,695, issued to Gilbert, when a pot is inserted into the sleeve, the outer sides of the pot fit within the taper of the sleeve but an empty void space is left underneath the pot which must then be tucked below the bottom of the pot to conceal it. The basic problem in applying a closed-bottom flat sleeve to a pot is that in going from a two-dimensional flat sleeve to a three-dimensional open sleeve, the shape of the opened sleeve does not conform to the shape of the pot.
There are no sleeves currently available which can be erected so that the sleeve closely conforms to the curvature of both the outer sidewall of the pot and to the bottom surface of the pot, whereby the lower portion of the sleeve forms an attractive decorative cover about the pot reminiscent of a preformed pot cover when the upper portion of the sleeve is detached. The object of the present invention is, therefore, to provide a flat, two-dimensional sleeve which is erectable into a three-dimensional wherein the erected sleeve has a shape which conforms to the shape of the pot without revealing unsightly extra material.
The present invention contemplates in a preferred embodiment a plant packaging system comprising a floral sleeve (also referred to herein as a “sleeve”) further comprising a combination of a protective upper sleeve portion (also referred to herein as an “upper portion”) and a decorative lower cover portion (also referred to herein as a “lower 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 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 be separate components which are attached together by various bonding materials or other sealing or attaching methods.
More specifically, in a preferred embodiment, 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 lower portion having a lower end, an upper end, an outer peripheral surface, and an expansion element for allowing expansion of a portion of the lower portion, and (2) an upper portion extending from the upper end of the lower 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 infolded or outfolded gusset, a pleated or folded area, overlapping folds, or elastic material. When the pot is inserted into the lower portion, the expansion element expands to allow the pot to fit into the lower portion of the sleeve. The lower portion is sized to substantially cover and conform to the outer peripheral and bottom surfaces of the pot once the lower 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 a sidewall of the sleeve in the erected position extends angularly from the bottom of the sleeve upwardly from the bottom. Preferably the sidewall 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, described above. More preferably, the sidewall of the sleeve in the expanded condition extends upwardly from the bottom at substantially the same angle at which the sidewall 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 sidewall 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 sidewall of the sleeve fit closely against the bottom and sidewall of the pot leaving substantially no void space or gaps there between. In an alternative preferred embodiment, if a gap does exist between the sidewall of the sleeve and the sidewall of the pot, the gap is substantially uniform for the entire length of the sidewall 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 sidewall 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 sidewall of the sleeve in the open state substantially conforms to the curvature of the outer peripheral surface of the pot. The sidewall 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 sidewall 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 a detaching element or assembly. 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. Alternatively, 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 a plurality of folds, the total lengths of which exceed one diameter of the bottom surface of the pot.
The upper portion, when present, may be detachable via a detaching element such as perforations, tear strips and zippers. The sleeve may have an extended portion extending from the upper portion for serving as a handle or support device. Further, an 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 lower portion when the upper portion of the sleeve is detached from the upper end of the lower portion. The expansion element may be infolded or outfolded 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 the bottom surface of the pot when the pot is inserted into the lower portion of the sleeve. 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 portion of the sleeve 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 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 sleeve, the pot having a floral grouping disposed therein, and wherein the pot is substantially surrounded and encompassed by the lower portion of the sleeve and the floral grouping is substantially surrounded and encompassed by the upper portion of the sleeve.
Further, the lower portion may include a bonding material for bondingly connecting to the upper portion. Also, the lower portion may include a bonding material for bondingly connecting to a pot disposed therein. Further, the upper portion may include a bonding material for bondingly connecting to the lower portion. The sleeve may further comprise part of a plant package which includes a pot disposed within the inner retaining space of the lower portion, 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 portion.
The lower portion of the 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, 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 outer peripheral surface 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 lower 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
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 has an opening 19 at 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 lie flatwise upon each other and are longitudinally sealed, connected, or otherwise continuous along first side 16 and 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 side 16 and second side 18 whereby the gusset 24 is inwardly folded between first panel 20 and second panel 22. The gusset 24 comprises the expansion element in this embodiment. The fold 26 may be straight (i.e.,
The construction of the lower end 14 of the sleeve 10, comprising the gusset 24 with the fold 26, permits the circular bottom of an object such as a potted plant to be disposed within the interior space 46 and therein causes a lower portion of the sleeve 10 to conform closely to the frusto-conical shape of the pot 70 as shown in
The sleeve 10 is demarcated into an upper portion 50 which is protective and a lower portion 52 which is decorative. The lower portion 52 of the sleeve 10 is sized to contain the pot 70 (
In a preferred embodiment, as shown in
The upper portion 50 of the sleeve 10 may optionally have a vertical detaching element 62 indicated as a plurality of vertical perforations 63 for facilitating removal of the upper portion 50 and which are disposed more or less vertically therein extending between the detaching element 54 of the sleeve 10 and the upper end 12 thereof. The upper portion 50 of the sleeve 10 is separable from the lower portion 52 of the sleeve 10 by tearing the upper portion 50 along both the vertical detaching element 62 and the detaching element 54, thereby separating the upper portion 50 from the lower portion 52 of the sleeve 10. The lower portion 52 of the sleeve 10 remains disposed as the base portion 56 about the pot 70 and as the skirt portion 58 about a floral grouping 84, forming a decorative cover 64 as shown in
As noted above, it will generally be desired to use the sleeve 10 as a covering for the plant or the floral grouping 84 contained within the pot 70, as shown in
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 mil. Often, the thickness of the sleeve 10 is in a range from about 0.5 mil to about 10 mil. Preferably, the sleeve 10 has a thickness in a range from about 1.0 mil to about 5 mil. 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 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 the floral grouping 84, as described herein. Additionally, an insulating material (not shown) such as bubble film, preferably one of two or more layers, can be utilized in order to provide additional protection for the item, such as the floral grouping 84, 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 the 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 from less than about 0.1 mil to about 10 mil, and preferably less than about 0.5 mil to about 2.5 mil, and most preferably from less than about 0.6 mil to about 2 mil. 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 a sleeve and wrapped about the pot 70 and the floral grouping 84 disposed therein. Preferably, the material comprises untreated or treated paper, metal foil, polymer film, non-polymer film, woven or nonwoven or synthetic or natural fabric, cardboard, fiber, cloth, burlap, or laminations or combinations thereof.
The term “polymer film” means a synthetic polymer such as a polypropylene or a naturally occurring polymer such as cellophane. A polymer film is relatively strong and not as subject to tearing (substantially non-tearable), as might be the case with paper or foil.
The material comprising the sleeve 10 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 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 comprising 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 84. The floral grouping 84 generally comprises a bloom or foliage portion and a stem portion. Preferably, the floral grouping 84 comprises a growing potted plant having a root portion (not shown) as well. However, it will be appreciated that the floral grouping 84 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 any of the terms “floral arrangement”, “potted plant” or “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 the 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, when present, is disposed as a strip or block on the inner surface 36 or 40 of the first and second panels 20 and 22 of the sleeve 10. The bonding material may also be disposed upon either outer surface 34 or 38 of the first and second panels 20 and 22 of the sleeve 10, as well as upon the pot 70. Further, the bonding material may be disposed as spots of bonding material, 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 and/or outer surfaces 34 and 38 of the first and second panels 20 and 22 of the sleeve 10 and/or the pot 70 or the decorative cover 64. The bonding material may be covered by a cover or release strip which can be removed prior to the use of the sleeve 10 or the decorative cover 64. The bonding material can be applied by means known to those of ordinary skill in the art. One method for disposing a bonding material, 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 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 affect 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 in the gusset 24 may be a straight fold 26 extending from the first side 16 to the second side 18, as shown in
When the pot 70 is deposited into the sleeve 10 having the straight fold 26, a portion 88 of the gusset 24 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 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, portions 88, 90 and 92 form the bottom 49 of the sleeve 10 in the expanded state as shown in
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 (see

The elastomeric lower 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 elastomeric lower portion 202 may be an elasticized or rubberized extension of 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
The elastomeric material of the sleeves 200-200c may comprise most or all of the elastomeric lower portions 202-202c of the sleeves 200-200c as shown in
It will be understood that the elastomeric lower portion, when expanded about the pot 70, may cover only the bottom 78 of the pot 70, or may cover the bottom 78 of the pot 70 and a portion of the outer peripheral surface 76 of the pot 70 above the bottom 78 of the pot 70. In yet another version (not shown) of the elastomeric sleeve, the elastomeric portion of the sleeve may be constructed in such a way that the bottom 78 of the pot 70 disposed within the sleeve may be covered by a non-elastomeric portion of the sleeve, while a portion of the outer peripheral surface 76 of the pot 70 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 peripheral surface 76 or bottom 78 of the pot 70. Finally, the elastomeric portion may comprise the entire sleeve, as shown in sleeve 200f in

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
In the embodiment of the sleeve formed using the apparatus of
The folded 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 the 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
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 single web of material 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 single web of material 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 the bonding material 300 distributed on different portions of the sleeve.
Sleeves formed in accordance with the present invention can also be formed from tubular materials (not shown) 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.
