Thermoplastic flower pot with a thin skirt

Description

FIELD OF THE INVENTION
The present invention relates to flower pot covers and more particularly, but not by way of limitation, to flower pot covers having a bottom and an upwardly extending sidewall wherein the sidewall has a thickness less than the thickness of the bottom.
DESCRIPTION OF RELATED ART
Flower pot covers have traditionally been disposed about the outer surfaces of flower pots to decorate the flower pot and to minimize the amount of water or potting medium which may spill from the flower pot. The materials typically used to form decorative flower pot covers are relatively thin. While such thin materials are attractive in that they provide the flower pot covers with a skirt having a loose, billowy appearance, such materials are susceptible to puncturing or tearing by sharp areas or edges on or near the bottom and sides of the flower pot which allows moisture to leak through the flower pot cover, possibly causing damage to carpet, furniture, tile, and other surfaces upon which the flower pot cover may be disposed.
However, if rigid or semi-rigid materials are used to produce flower pot covers and make the flower pot covers less susceptible to puncturing or tearing, then the skirt of the flower pot cover loses its loose, billowy appearance. Thus, it would be of benefit to the floral industry and to the end purchaser to have a flower pot cover constructed of rigid or semi-rigid material, but which has a skirt having a loose, billowy appearance.

Description of FIGS. 1-5
Shown in FIG. 1 is a flower pot cover 10 constructed in accordance with the present invention. The flower pot cover 10 is formed from a sheet of material 12 (FIGS. 3-5) shaped to define a receiving space 14 adapted to receive an object, such as a flower pot 15.
The flower pot cover 10 has a base or lower portion 16 having an outer peripheral surface 18. The base portion 16 has an upper end 20, a lower end 22 and a continuous sidewall 24 which defines the outer peripheral surface 18 of the base portion 16. The sidewall 24 of the base portion 16 of the flower pot cover 10 has a thickness 26 (FIG. 2). A skirt or upper portion 30 of the flower pot cover 10 is positioned circumferentially about the upper end 20 of the base portion 16 of the flower pot cover 10 and extends generally outwardly and upwardly therefrom substantially as shown. The base portion 16 of the flower pot cover 10 is further provided with a bottom 32 (FIG. 2) having a thickness 34 (FIG. 2) which is greater than the thickness 26 of the sidewall 24 of the base portion 16 and a thickness 36 (FIG. 2) of the skirt portion 30.
The flower pot cover 10 further includes a basal portion 37 having a basal rim portion 38 and a basal base or bottom portion 39. The basal base portion 39 is disposed substantially adjacent the bottom 32 of the base portion 16 of the flower pot cover 10 and the basal rim portion 38 of the basal portion 37 extends circumferentially about an interior surface 41 of the lower end 22 of the base portion 16 of the flower pot cover 10. The basal rim portion 38 has an upper end 40, a lower end 42 and a height 44 extending generally between the upper and lower ends 40 and 42, respectively, of the basal rim portion 38.
The skirt portion 30 of the flower pot cover 10 has a first end 46, a second end 48 and an outer peripheral edge 50. The thickness 36 of the skirt portion 30 of the flower pot cover 10 substantially corresponds to the thickness 26 of the sidewall 24 of the base portion 16 of the flower pot cover 10.
The flower pot cover 10 may be further provided with a plurality of overlapping folds, only one of which is designated by the reference numeral 52. The overlapping folds 52 extend at various distances and at various angles over the outer peripheral surface 18 of the flower pot cover 10. The overlapping folds 52 may be connected, at least partially connected, or substantially free standing folds independent of adjacent folds. When it is desired that the overlapping folds 52 be either partially connected or connected, the connection of the overlapping folds 52 may be accomplished by using a heat sealable material and heat sealing the overlapping folds 52. Alternatively, the overlapping folds 52 may be adhesively or cohesively connected. When connected, the overlapping folds 52 cooperate to provide the flower pot cover 10 with enhanced mechanical reinforcement and thereby provide the flower pot cover 10 with a shape sustaining configuration.
The overlapping folds 52 and the manner in which the overlapping folds 52 provide the flower pot cover 10 with the enhanced mechanical reinforcement are explained in more detail in copending U.S. application Ser. No. 08/347,611, entitled "Flower Pot Assembly Formed From A Sheet With An Opening", filed Nov. 30, 1994, and which is expressly incorporated herein by reference.
The sheet of material 12 utilized in the construction of the flower pot cover 10 desirably has sufficient memory so that the flower pot cover 10 formed from the sheet of material 12 may be flattened (not shown) for shipping and storage purposes and subsequently unflattened for use. That is, the sheet of material 12 used in the formation of the flower pot cover 10 desirably posses sufficient memory so that the flower pot cover 10 formed from the sheet of material 12 can be easily unflattened to assume the preformed shape of the flower pot cover 10 without any substantial loss of the preformed shape and without having to be remolded thereby providing a flexible, yet shape sustaining flower pot cover 10.
Shown in FIG. 3 is the sheet of material 12 utilized in the formation of the flower pot cover 10. The sheet of material 12 has a first end 54, a second end 56, a first side 58, a second side 60, an upper surface 62 and a lower surface 64. The sheet of material 12 has a length 66 extending between the first and the second sides 58 and 60, respectively, of the sheet of material 12; and a width 68 extending generally between the first and the second ends 54 and 56, respectively, of the sheet of material 12.. The first end 54, the second end 56, the first side 58 and the second side 60 cooperate to provide the sheet of material 12 with an outer peripheral edge 70.
The sheet of material 12 may be constructed of a single sheet of material or a plurality of sheets of the same or different types of materials. The sheets of material may be separate sheets or the sheets may be connected together or laminated together.
Although the sheet of material 12 is shown in FIG. 3 as being generally square shaped, it is to be understood that the sheet of material 12 may assume any geometric, non-geometric or asymmetrical shape. For example, the sheet of material 12 may be square, rectangular, circular, heart-shaped or the like. The shape of the sheet of material 12 will depend on the configuration of the flower pot cover 10 to be formed from the sheet of material 12.
The sheet of material 12 is further provided with a basal layer 72 for forming the basal portion 37 of the flower pot cover 10. The basal layer 72 is disposed on a portion of the sheet of material 12 to be formed into the bottom 32 of the base portion 16 of the flower pot cover 10. The basal layer 72 may be a separate sheet of material which is affixed to the sheet of material 12 during or after the fabrication of the sheet of material 12 and/or the basal layer 72 may be integrally formed with the sheet of material 12 (FIG. 25).
Referring now to FIG. 3 in combination with FIG. 4, the basal layer 72 has an upper surface 74 and may be provided with a lower surface 76 (FIG. 4) when the basal layer 72 is formed from a separate sheet of material. The lower surface 76, when present, is positioned adjacent the upper surface 62 of the sheet of material 12, and the basal layer 72 may be affixed to the sheet of material 12 via any suitable bonding material.
The basal layer 72, as shown in FIG. 3 is generally disc shaped and has a diameter 78 and a periphery 80. However, it is to be noted that the basal layer 72 may assume any geometric, non-geometric or asymmetrical shape such as a square, a rectangle or an oval.
The basal layer 72, which functions to enhance the strength, rigidity and the resistance to tearing, puncturing, abrading and leaking of the bottom 32 and lower end 22 of the base portion 16 of the flower pot cover 10 formed from the sheet of material 12, may be constructed of a single layer of material (FIG. 3) or a plurality of layers of the same or different types of materials (FIG. 26), or the basal layer 72 may comprise an effective amount of a material applied to the sheet of material 12. Examples of such materials which may be applied to the sheet of material 12 to form the basal layer 72 are foams, inks, lacquers, polymers or the like and combinations thereof.
The sheet of material 12 has a thickness 82 (FIG. 4) that can vary widely and any thickness of the sheet of material 12 may be utilized in accordance with the present invention as long as the sheet of material. 12 can be formed into the flower pot cover 10 as described herein. Typically, the thickness 82 of the sheet of material 12 will be in a range from about 0.1 mils to about 30 mils, desirably in a range from about 0.1 mils to about 10 mils and more desirably in a range from about 0.4 to about 2 mils.
The basal layer 72 has a thickness 84 that can vary widely and any thickness of the basal layer 72 can be utilized in accordance with the present invention as long as the sheet of material 12 having the basal layer 72 disposed thereon can be formed into the flower pot cover 10, as described herein. Typically, the thickness 84 of the basal layer 72 is in a range from about 0.1 mils to about 500 mils, desirably in a range from about 0.3 mil to about 100 mils and more desirably in a range from about 0.3 mil to 30 mils. The basal layer 72 is generally flexible, but may be relatively rigid as compared to the sheet of material 12.
The above stated shapes, thicknesses and construction of the sheet of material 12 and the basal layer 72 will apply to all of the embodiments of the sheet of material 12 and the basal layer 72 which are discussed herein.
The basal layer 72, and the portion of the sheet of material 12 either immediately below the basal layer 72, or integral thereto, cooperate to define the basal portion 37 of the flower pot cover 10 having a thickness 88. That is, the thickness 82 of the sheet of material 12 and the thickness 84 of the basal layer 72 cooperate to define the thickness 88 of the basal portion 37 of the flower pot cover 10.
The sheet of material 12 has a peripheral portion 90 surrounding the basal layer 72 and extending a distance 92 from the periphery 80 of the basal layer 72 to the outer peripheral edge 70 of the sheet of material 12. The peripheral portion 90 of the sheet of material 12 has a thickness which is equal to the thickness 82 of the sheet of material 12 and which is less than the thickness 88 of the basal portion 37 of the flower pot cover 10.
In a preferred embodiment, the sheet of material 12 and the basal layer 72 are constructed from one or more sheets of polypropylene film (a 20".times.15" sheet of Mobil 270 ABW white opaque film laminated to a 20".times.15" sheet of Mobil 220 AB clear film) having a thickness in a range of from less than about 0.5 mil to about 1 mil. The layers of material comprising the sheet of material 12 may be connected together or laminated or may be separate layers.
The sheet of material 12 and the basal layer 72 may be constructed from any suitable material that is capable of being formed into the flower pot cover 10. For example, the sheet of material 12 or the basal layer 72 may be constructed out of paper (untreated or treated in any manner), cellophane, foil, polymer film, fabric (woven, nonwoven, synthetic, natural and combinations thereof) and combinations thereof.
The sheet of material 12 and/or the basal layer 72 may vary in color. Further, the sheet of material 12 and/or basal layer 72 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 sheet of material 12 and/or the basal layer 72 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.
In addition, the sheet of material 12 and/or the basal layer 72 may have various colorings, coatings, flocking and/or metallic finishes, or other decorative surface ornamentation applied separately or simultaneously thereon. Alternatively, the sheet of material 12 and/or the basal layer 72 may be characterized totally or partially by pearlescent, translucent, transparent, iridescent or the like qualities. Each of the above-named characteristics may occur alone or in combination and each surface of the sheet of material 12 and/or the basal layer 72 may vary in the combination of such characteristics.
As shown in FIG. 5, a plurality of sheets of material 12 are stacked one on top of the other to form a pad 94. The plurality of sheets of material 12 are positioned so that the first sides 58, the second sides 60, the first ends 54 and the second ends 56 of the sheets of material 12 in the pad 94 are generally aligned. With the exception of the first or top sheet of material 12, the upper surface 62 of each sheet of material 12 is disposed generally adjacent the lower surface 64 of an adjacent sheet of material 12 in the pad 94.
The flower pot 15 is disposed upon the upper surface 74 of the basal layer 72 of the sheet of material 12 disposed generally on the top of the pad 96. The flower pot 15 is shaped to define a receiving space 96 for receiving an object, such as a floral grouping 98. The floral grouping 98 has a stem portion 100 which is disposed within the receiving space 96 of the flower pot 15 and a bloom portion 102 which extends generally upwardly therefrom. The flower pot 15 has a closed bottom end 104, an open upper end 106 and a continuous sidewall 108 extending generally between the bottom end 104 and the upper end 106 thereof.
One method for forming the sheet of material 12 having the basal layer 72 (FIG. 5) into the flower pot cover 10 is to dispose the bottom end 104 of the flower pot 15 onto the basal layer 72 substantially as shown in FIG. 5. Thereafter, the peripheral portion 90 of the sheet of material 12 is lifted and pressed about the sidewall 108 of the flower pot 15 causing a portion of the upper surface 62 of the sheet of material 12 to engage the sidewall 108 of the flower pot 15. The lower surface 64 of the sheet of material 12 thereby forms the outer peripheral surface 18 of the flower pot cover 10, the upper surface 62 of the sheet of material 12 thereby forms the interior surface 41 of the flower pot cover 10, the basal portion 86 thereby forms the bottom 32 of the flower pot cover 10 and the outer peripheral edge 70 of the sheet of material 12 thereby forms the outer peripheral edge 50 of the skirt portion 30 of the flower pot cover 10.
The sheet of material 12 can also be formed into the flower pot cover 10 employing the method disclosed in U.S. Pat. No. 4,733,521 entitled "Cover Forming Apparatus" issued to Weder et al., on Mar. 29, 1988, which is expressly incorporated herein by reference. Alternatively,-the sheet of material 12 may be formed into the flower pot cover 10 by positioning the sheet of material 12 between a female die and a male die as disclosed in U.S. Pat. No. 4,773,182 entitled "Article Forming System" issued to Weder et al., on Sep. 27, 1988, which is also hereby incorporated herein by reference.
The bottom end 104 of the flower pot 15 desirably has a circumference less than the circumference of the basal layer 72 so that when the sheet of material 12 having the basal layer 72 thereon is formed about the flower pot 15, an excess portion of the basal layer 72 extends about the bottom end 104 of the sidewall 108 of the flower pot 15 and cooperates with the sheet of material 12 to form the basal rim portion 38 of the basal portion 37 of the flower pot cover 10. It should be understood that the height 44 of the basal rim portion 38 of the basal portion 37 of the flower pot cover 10 can vary and such will be dependent upon the circumference of the bottom end 104 of the flower pot 15 and the circumference of the basal layer 72. Desirably, however, the height 44 of the basal rim portion 38 of the basal portion 37 will be in a range of about one-fourth to one-third the height of the base portion 16 of the flower pot cover 10.
Description of FIGS. 6-7
Shown in FIGS. 6 and 7 is a flower pot cover former and band applicator apparatus designated by the reference numeral 112. The flower pot cover former and band applicator apparatus 112 may be constructed and operated similar to the cover forming device described in detail in U.S. Pat. No. 4,733,521 entitled "Cover Forming Apparatus" issued to Weder on Mar. 29, 1988 which is hereby incorporated herein by reference.
The flower pot cover former and band applicator device 112 comprises a band applicator 114 and a flower pot cover former 116. The flower pot cover former 116 has a support platform 118 with an opening 120 formed therein. A band 122 is disposed circumferentially about the opening 120 in the support platform 118.
The sheet of material 12 is positioned on an upper surface 124 on the support platform 118 such that the basal layer 72 on the sheet of material 12 is positioned over the opening 120 in the support platform 118. The flower pot 15 is positioned above the basal layer 72 and is moved in a direction 126 (FIG. 6) into the opening 120 of the flower pot cover former and band applicator device 112. As the flower pot 15 is moved into the opening 120, the basal layer 72 is formed about the bottom end 104 of the flower pot 15 and a portion of the sheet of material 12 is pressed against the sidewall 108 of the flower pot 15 thereby forming the flower pot cover 10 about the flower pot 15. The flower pot cover 10 is then secured about the flower pot 15 by the band 122. The flower pot 15 having the flower pot cover 10 secured thereto is then moved in a direction 128 (FIG. 7) out of the opening 120 in the support platform 118.
Instead of securing the flower pot cover 10 about the flower pot 15 via the band 122, the flower pot cover 10 formed from the sheet of material 12 may be secured to the flower pot 15 by the use of one or more bonding materials. For example, the upper surface 62 of the sheet of material 12 may have a bonding material disposed upon a portion thereof. When the sheet of material 12 is disposed about the flower pot 15, at least a portion of the upper surface 62 of the sheet of material 12 contacts the sidewall 108 of the flower pot 15 and is thereby bonded and held about the flower pot 15 via the bonding material. It should be noted that the bonding material may be disposed either on the upper surface 62 of the sheet of material 12 or on the upper surface 74 of the basal layer 72 or both.
The bonding material may cover a portion of the sheet of material 12 or the bonding material may entirely cover the sheet of material 12. The bonding material may be disposed on the upper surface 62 of the sheet of material 12 in the form of a strip or in the form of spaced apart spots. One method for disposing a bonding material on a sheet of material 12, 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 is expressly incorporated herein by reference.
Description of FIGS. 8-12
Shown in FIG. 8 is the formation of a basal layer 72a on a sheet of material 12a utilizing a flower pot cover forming apparatus 130. The flower pot cover forming apparatus 130 may be constructed in a similar manner as the modified article forming system disclosed in U.S. Pat. No. 4,773,182, entitled "Article Forming System", issued to Weder on Sep. 27, 1988, which is expressly incorporated herein by reference.
A material supply, designated by the reference numeral 132, comprises a roll of material 134 rotatably mounted upon a shaft 136 for permitting material to be rollingly withdrawn from the roll of material 134. The sheet of material 12a is produced from the roll of material 134 and is similar to the sheet of material 12 herein before described. The sheet of material 12a is formed by severing or disconnected a segment from the roll of material 134 using a cutting device 138.
The roll of material 134 has a leading edge 140. In operation, the leading edge 140 is gripped and withdrawn from the roll of material 134 in a direction 142 via rollers 144 and 146. The material is unrolled from the roll of material 134 and fed through rollers 144 and 146 and then through rollers 148 and 150 until a desired length of material to form the sheet of material 12a has been withdrawn from the roll of material 134. The sheet of material 12a is then formed by severing a segment from the roll of material 134 via the cutting device 138. Subsequently, a basal layer 72a is moved in a direction 152 so that the basal layer 72a is disposed upon the upper surface 62a of the sheet of material 12a and affixed thereto via a suitable bonding material, for example.
Once the basal layer 72a has been affixed to the sheet of material 12a, the sheet of material 12a is advanced via rollers 154 and 156 to a flower pot cover forming position of the flower pot cover forming apparatus 130 wherein the sheet of material 12a is positioned above a female die 158 and below a male die 160 of the flower pot cover forming apparatus 130.
To form the sheet of material 12a into the flower pot cover 10, the male die 160 is moved in a direction 162 so that the male die 160 engages the basal layer 72a affixed to the sheet of material 12a and moves the sheet of material 12a into an opening 164 of the female die 158 thereby forming the sheet of material 12a into the flower pot cover 10 as heretofore described. The male die 168 is then retracted and the flower pot cover 10 removed from the flower pot cover forming apparatus 130.
If desired, two separate rolls of material (not shown) with one of the rolls of material having a first material and the other roll of material having a second material may be utilized in the formation of the flower pot cover 10. When employing two separate rolls of material, the first material is withdrawn from the first roll of material and the second material is simultaneously withdrawn from the second roll of material so that the first and the second materials are overlaid and provided in a manner as generally shown herein for severing by the cutting device 138 from the first and the second rolls of material to provide dual sheets of material.
FIG. 9 shows a flower pot cover forming apparatus 130b which is similar to the flower pot cover forming apparatus 130 shown in FIG. 8 except as noted below. When employing the flower pot cover forming apparatus 130b, a sheet of material 12b is formed from the roll of material 134b via tearing a segment from the roll of material 134b along a row of perforations 166. The sheet of material 12b is then advanced to a flower pot cover forming position of the flower pot cover forming apparatus 130b wherein the sheet of material 12b is disposed above a female die 158b and below a male die 160b, as heretofore described. A basal layer 72b is the disposed on an upper surface 62b of the sheet of material 12b.
To form the flower pot cover 10 from the sheet of material 12b, the male die 160b is moved in a direction 162b so that the male die 160b engages the basal layer 72b and moves the basal layer 72b and the sheet of material 12b into an opening 164b of the female die 158b. Thereafter, the male die 160b is retracted and the flower pot cover 10 is removed from the opening 164b of the female die 158b so as to form a flower pot cover as heretofore described.
FIG. 10 shows a flower pot cover forming apparatus 130c similar to the flower pot cover forming apparatus 130 shown in FIG. 8 except that when employing the flower pot cover forming apparatus 130c, a basal layer 72c is disposed automatically via a vacuum apparatus 168 upon an upper surface 62c of a sheet of material 12c.
A segment of material is severed from a roll of material 134c via a cutting assembly 138c so as to form a sheet of material 12c as herein before described. The basal layer 72c is removed from a stack of basal layers (not shown) and deposited on an upper surface 62c of the sheet of material 12c via the vacuum apparatus 168 prior to the sheet of material 12c being positioned in the flower pot cover forming position of the flower pot cover forming apparatus 130c wherein the sheet of material 12c is positioned above a female die 158c and below a male die 160c. Once the basal layer 72c is deposited upon the upper surface 62c of the sheet of material 12c, the vacuum apparatus 168 releases the vacuum and is positioned to receive another basal layer 72c from the stack of basal layers (not shown).
The sheet of material 12c having the basal layer 72c disposed thereon is then advanced to the flower pot cover forming position of the flower pot cover forming apparatus 130c as described above. The basal layer 72c may or may not be bondingly connected to the sheet of material 12c prior to the formation of a flower pot cover 10.
To form a flower pot cover from the sheet of material 12c, the male die 160c is moved in a direction 162c so that the male die 160c engages the basal layer 72c and moves the basal layer 72c and the sheet of material 12c into an opening 164c of the female die 158c so as to form the sheet of material 12c into a flower pot cover having a basal portion similar to the flower pot cover 10 described with reference to FIG. 1. Thereafter, the male die 160c is retracted and the flower pot cover so formed is removed from the opening 164c of the female die 158c.
FIG. 11 shows a flower pot cover forming apparatus 130d which is similar to the flower pot cover forming apparatus 130 shown in FIG. 8 except that when employing the flower pot cover forming apparatus 130d, a spray assembly 170 sprays an effective amount of material 172 on an upper surface 62d of a sheet of material 12d so as to form a basal layer 72d on the sheet of material 12d prior to the formation of a flower pot cover from the sheet of material 12d. Any suitable material which can be sprayed onto the sheet of material 12d and cured to provide the basal layer 72d can be utilized. For example, foamable compounds, such as insulating foams or foaming inks, both of which are commercially available and known in the art, can be utilized to form the basal layer 72d.
Once an effective amount of a material 172 has been sprayed onto the sheet of material 12d to form the basal layer 72d and the material 172 has cured, the sheet of material 12d with the basal layer 72d formed thereon is positioned in a flower pot cover forming position wherein the sheet of material 12d is positioned generally above a female die 158d and generally below a male die 160d of the flower pot cover forming apparatus 130d. To form a flower pot cover from the sheet of material 12d, the male die 160d is moved in a direction 162d so that the male die 160d engages the basal layer 72d and thus moves the basal layer 72d and the sheet of material 12d into an opening 164d of the female die 158d to form a flower pot cover. Thereafter, the male die 160d is retracted and the flower pot cover so formed is removed from the opening 164d of the female die 158d.
FIG. 12 shows a flower pot cover forming apparatus 130e similar to the flower pot cover forming apparatus 130 shown in FIG. 8 except that when employing the flower pot cover forming apparatus 130e, a basal layer 72e is disposed automatically on a sheet of material 12e while the sheet of material 12e is in a flower pot cover forming position of the flower pot cover forming apparatus 130e.
The sheet of material 12e is formed by severing a segment of material from a roll of material 134e via a cutting assembly 138e. The sheet of material 12e is then advanced via rollers 154e and 156e so as to be positioned between a female die 158e and a male die 160e of the flower pot cover forming apparatus 130e.
The male die 168e picks up the basal layer 72e from a stack of basal layers (not shown) and deposits the basal layer 72e upon an upper surface 62e of the sheet of material 12e while the sheet of material 12e is in the flower pot cover forming position of the flower pot cover forming apparatus 130e.
The basal layer 72e may have a preformed "saucer" shape similar to that shown in FIG. 13 which engagingly fits upon a lower end 174 of the male die 160e. Alternatively, the basal layer 72e may be substantially flat as shown in FIG. 12.
To form a flower pot cover from the sheet of material 12e, the male die 160e having the basal layer 72 supported on the lower end 174 thereof, is moved in the direction 162e so that the basal layer engages the sheet of material 12e. Continued movement of the male die 160e in the direction 162e moves the basal layer 72e and the sheet of material 12e into an opening 164e of the female die 158e to form a flower pot cover. Thereafter, the male die 160e is retracted and the flower pot cover so formed is removed from the opening 164e of the female die 158e.
Although the methods for forming the flower pot cover 10 illustrated in FIGS. 8-12 show the material supply being in the form of a roll of material, it is to be understood that other systems may be utilized to provide the material supply. For example, the material supply could also be a plurality of sheets of material 12 stacked in the form of a pad, such as the pad 95 formed from a plurality of sheet of material 12 shown in FIG. 5.
Description of FIGS. 13-15
FIG. 13 illustrates a method of forming the flower pot cover 10 of FIGS. 1 and 2 having the basal portion 37 from a preformed flower pot cover 176. The preformed flower pot cover 176 defines a receiving space 178 and has an open upper end portion 180 and a closed bottom end 182.
The preformed flower pot cover 176 may be constructed in a similar manner as the decorative flower pot cover disclosed in U.S. Pat. No. 4,773,182, entitled "Article Forming System", issued to Weder on Sep. 27, 1988, which is expressly incorporated herein by reference.
To form the flower pot cover 10 from the preformed flower pot cover 176, the preformed flower pot cover 176 is disposed on a conveyor assembly 184 and moved in a direction 186 to position the preformed flower pot cover 176 below a basal applicator assembly 188. The basal applicator assembly 188 comprises a vacuum cup 190 which applies a vacuum to hold a saucer shaped basal layer insert 192 thereto. The vacuum cup 190 and the basal layer insert 192 are moved in a direction 194 into and through the receiving space 178 formed in the preformed flower pot cover 176 to a position wherein the basal layer insert 192 is disposed within the receiving space 178 substantially adjacent the bottom end 182 of the preformed flower pot cover 176.
Thereafter, vacuum is removed from the vacuum cup 190 of the basal applicator assembly 188 so that the vacuum cup 190 releases the basal layer insert 192. The vacuum cup 190 of the basal applicator assembly 188 is then returned to a position wherein the vacuum cup 190 of the basal applicator assembly 188 receives another basal layer insert 192 for inserting into another preformed flower pot cover 176.
To facilitate the positioning of the basal layer insert 192 within the receiving space 178 of the flower pot cover 176 so that the basal layer insert 192 is disposed substantially adjacent the bottom end 182 of the preformed flower pot cover 176, the basal layer insert 192 has a circumference equal to or less than the interior circumference of the bottom end 182 of the preformed flower pot cover 176. The basal layer insert 192 may be secured to the bottom end 182 of the preformed flower pot cover 176 by coating a lower end 196 of the basal layer insert 192 and/or the bottom end 182 of the preformed flower pot cover 176 with a bonding material prior to positioning the basal layer insert 192 substantially adjacent the bottom end 182 of the preformed flower pot cover 176.
FIG. 14 illustrates a method for forming a flower pot cover 10f from the preformed flower pot cover 176 having a basal portion 37b formed from a basal layer insert 192a. The basal layer 192a is substantially identical in construction as the basal layer 192 described with reference to FIG. 13 except that the basal layer 192a is provided with an interior circumference which is at least equal to the exterior circumference of the bottom end 182 of the preformed flower pot cover 176.
To form the flower pot cover 10f, the saucer shaped basal layer insert 192a is disposed on the conveyor assembly 184 and moved in the direction 186 to position the basal layer insert 192a below a preformed flower pot cover applicator assembly 188a. A vacuum cup 190a of the preformed flower pot cover applicator assembly 188a, which applies a vacuum to hold the preformed flower pot cover 176 thereto, and the preformed flower pot cover 176 are moved in a direction 194a whereby the bottom end 182 of the preformed flower pot cover 176 is positioned with the basal layer insert 192a substantially as shown.
When the basal layer insert 192a is positioned about the bottom end 182 of the preformed flower pot cover 176, the vacuum from the vacuum cup 190a of the preformed flower pot cover applicator assembly 188a is released and the vacuum cup 190a is retracted to a loading position (not shown) for obtaining another preformed flower pot cover 176.
A bonding material may be disposed upon the bottom end 182 of the preformed flower pot cover 176 for bonding the bottom end 182 of the preformed flower pot cover 176 to the basal layer insert 192a. Alternatively, a bonding material may be disposed upon a lower end 196a of the basal layer insert 192a for bonding the basal layer insert 192a about the bottom end 182 of the preformed flower pot cover 176. Alternatively, a cohesive bonding material may be disposed upon both the lower end 196a of the basal layer insert 192a and on the bottom end 182 of the preformed flower pot cover 176 for bonding the basal layer insert 192a to the preformed flower pot cover 176.
Illustrated in FIG. 15 is a method for forming a flower pot cover 10g having a basal portion 37b from the preformed flower pot cover 176 and a sprayable material 200. To form the flower pot cover 10g from the preformed flower pot cover 176 and the sprayable material 200, the preformed flower pot cover 176 is disposed on the conveyor assembly 184 and moved in the direction 186 to position the preformed flower pot cover 176 below a spray applicator assembly 202. The spray applicator assembly 202 comprises a spray applicator head 204 which is moved in the direction 194 through the receiving space 178 formed in the preformed flower pot cover 176. While the spray applicator head 204 of the applicator assembly 202 is disposed within the receiving space 178 of the preformed flower pot cover 176, an effective amount of the sprayable material 200 capable of providing a basal layer 203 is sprayed about the bottom end 178 of the preformed flower pot cover 176 via the spray applicator head 204 so as to form the flower pot cover 10g having the basal portion 37b. Thereafter, the spray applicator head 204 is retracted to a position (not shown) for awaiting the next preformed flower pot cover 176.
Description of FIGS. 16-19
Illustrated in FIG. 16 is a flower pot cover 10h constructed in accordance with the present invention. The flower pot cover 10h is formed from a sheet of material 12h (FIG. 17) shaped to define a receiving space 14h adapted to receive an object, such as a flower pot 15 and a floral grouping 98.
The flower pot cover 10h has a base or lower portion 16h having an outer peripheral surface 18h. The base portion 16h has an upper end 20h, a lower end 22h and a continuous sidewall 24h which defines the outer peripheral surface 18h of the base portion 16h. A skirt or upper portion 30h of the flower pot cover 10h is positioned circumferentially about the upper end 20h of the base portion 16h of the flower pot cover 10h and extends generally outwardly and upwardly therefrom substantially as shown in FIG. 16. The base portion 16h of the flower pot cover 10h is further provided with a bottom 32h.
The flower pot cover 10h further includes a basal portion 37h having a basal rim portion 38h and a basal base or bottom portion 39h. The basal base portion 39h is disposed substantially adjacent the bottom 32h of the base portion 16h of the flower pot cover 10h and the rim portion 38h of the basal portion 37h extends circumferentially about an interior surface (not shown) of the lower end 22h of the base portion 16h of the flower pot cover 10h. The basal rim portion 38h has an upper end 40h, a lower end 42h and a height (not shown) extending generally between the upper and lower ends 40h and 42h, respectively, of the basal rim portion 38h.
The skirt portion 30h of the flower pot cover 10h has a first end 46h, a second end 48h and an outer peripheral edge 50h. An upper sleeve portion 206 of the flower pot cover lob extends about the floral grouping 98 disposed within the receiving space 14h of the flower pot cover 10h so as to provide the floral grouping with a protective covering. Typically, the upper sleeve portion 206 of the flower pot cover 10h is removably connected to the outer peripheral edge 50h of the skirt portion 30h of the flower pot cover 10h.
To facilitate the removal of the upper sleeve portion 206 from the skirt portion 30h of the flower pot cover 10h, the flower pot cover 10h is provided with perforations 208 extending generally between the skirt portion 30h and the upper sleeve portion 206 substantially as shown. The upper sleeve portion 206 remains formed in a position extending about and above the floral grouping 98 until it is desired to remove the upper sleeve portion 206 from the flower pot cover 10h. The upper sleeve portion 206 may be removed from the flower pot cover 10h by tearing along the perforations 208 extending between the skirt portion 30h and the upper sleeve portion 206 of the flower pot cover 10h. Once the perforations are torn, the upper sleeve portion 206 may be lifted from the flower pot cover 10h and removed therefrom.
Illustrated in FIG. 17 is the sheet of material 12h which is utilized in the formation of the flower pot cover 10h (FIG. 16). The sheet of material 12h has a first end 54h, a second end 56h, a first side 58h, a second side 60h, an upper surface 62h and a lower surface (not shown). The sheet of material 12h has a length 66h extending between the first and the second sides 58h and 60h, respectively, thereof; and a width 68h extending generally between the first and the second ends 54h and 56h, respectively, thereof. The first end 54h, the second end 56h, the first side 58h and the second side 60h cooperate to provide the sheet of material 12h with an outer peripheral edge 70h.
The sheet of material 12h is further provided with a basal layer 72h for forming the basal portion 37h of the flower pot cover 10h. The basal layer 72h is disposed on the portion of the sheet of material 12h to be formed into a bottom 32h of a base portion 16h of the flower pot cover 10h, which will be discussed in more detail hereinafter. The basal layer 72h may be a separate sheet of material which is affixed to the sheet of material 12h and/or the basal layer 72h may be formed integrally with the sheet of material 12h.
The basal layer 72h has an upper surface 74h and may be provided with a lower surface (not shown) when the basal layer 72h is formed from a separate sheet of material which is affixed to the sheet of material 12h; and the basal layer 72 may be affixed to the sheet of material 12h via a suitable bonding material.
The basal layer 72h, which has a diameter 78h and a basal periphery 80h, and the portion of the sheet of material 12h either immediately below the basal layer 72h, or integral thereto, cooperate to define the basal portion 37h of the flower pot cover 10h. Thus, the basal portion 37h of the flower pot cover 10h has a thickness greater than the thickness of the continuous sidewall 24h of the base portion 16h of the flower pot cover 10h.
The sheet of material 12h is further provided with a peripheral portion 90h which forms the continuous sidewall 24h of the base portion 16h of the flower pot cover 10h and the skirt portion 30h of the flower pot cover 10h when the sheet of material 12h is formed into the flower pot cover 10h. The peripheral portion 90h of the sheet of material 12h surrounds the basal layer 72h of the sheet of material 12h and extends a distance 210 outwardly from the basal periphery 80h of the basal layer 72h to a periphery 212 of the peripheral portion 90h of the sheet of material 12h.
The sheet of material 12h is further provided with a sheet extension portion 216 which forms the upper sleeve portion 206 of the flower pot cover 10h when the sheet of material 12h is formed into the flower pot cover 10h. The sheet extension portion 216 of the sheet of material 12h generally surrounds the periphery 212 of the peripheral portion 90h of the sheet of material 12h and extends a distance 218 outwardly therefrom to the outer peripheral edge 70h of the sheet of material 12h. The sheet of material 12h is further provided with perforations 208 extending about the periphery 212 of the peripheral portion 90h of the sheet of material 12h. As previously stated, the upper sleeve portion 206 of the flower pot cover 10h can be removed from the skirt portion 30h of the flower pot cover 10h by tearing along the perforations 208 extending between the skirt portion 30h and the upper sleeve portion 206.
Typically, the sheet extension portion 216 is integrally formed with the peripheral portion 90h of the sheet of material 12h. However, it is to be understood that the sheet extension portion 216 may be formed from a separate sheet of material which is positioned and attached circumferentially about the periphery 212 of the peripheral portion 90h of the sheet of material 12h.
A bonding material 220, such as an adhesive (FIG. 17), may be disposed on a portion of the upper surface 62h of the sheet extension portion 216 of the sheet of material 12h. Typically, the bonding material 220 extends circumferentially near the outer peripheral edge 70h of the sheet of material 12h.
The flower pot cover 10h may be formed from the sheet of material 12h by any method which has been described above or which is known in the art. For example, the sheet of material 12h can be formed into the flower pot cover 10h by the method disclosed in U.S. Pat. No. 5,073,161, entitled "Apparatus for Making a Flower Pot or Flower Pot Cover With Controlled Pleats", issued to Weder et al., Dec. 17, 1991, which is expressly incorporated herein by reference.
Illustrated in FIG. 18 is the flower pot cover 10h which has been formed from the sheet of material 12h. Once the sheet of material 12h has been formed into the flower pot cover 10h, the basal portion 37h and the peripheral portion 90h of the sheet of material 12h forms the base portion or lower portion 16h and the skirt portion 30h of the flower pot cover 10h in a similar manner as the basal portion 37 and the peripheral portion 90 of the sheet of material 12 forms the base portion 16 and the skirt portion 30 of the flower pot cover 10, herein before described with reference to FIG. 1. The sheet extension portion 216 of the sheet of material 12h extends a distance 218 outwardly from the outer peripheral edge 50h of the skirt portion 30h of the flower pot cover 10h when the sheet of material 12h has been formed into the flower pot cover 10h.
As shown in FIG. 19, the sheet extension portion 216 forms the upper sleeve portion 206 of the flower pot cover 10h, and provides a protective covering for the floral grouping 98 disposed in the receiving space 14h of the flower pot cover 10h. To form the sheet extension portion 216 into the upper sleeve portion 206, the flower pot 15 having the floral grouping 98 disposed therein is disposed in the receiving space 14h of the flower pot cover 10h so that the lower end 100 of the flower pot 15 is disposed generally adjacent the basal portion 37h formed in the lower end 22h of the base portion 16h of the flower pot cover 10h. The sheet extension portion 216 is then lifted and formed about the floral grouping 98 so that a portion of the outer peripheral edge 70h of the sheet of material 12h which forms the sheet extension portion 216 of the flower pot cover 10h extends above the floral grouping 98 and forms an open upper end 222.
The open upper end 222 may be closed by bondingly connecting adjacent portions of the open upper end 222 via the bonding material 220 located near the open upper end 222 of the upper sleeve portion 206 of the flower pot cover 10h, substantially as shown in FIG. 16.
In addition to the perforations 208, the upper sleeve portion 206 may also include perforations (not shown) extending between the perforations 208 and the open upper end 222 of the upper sleeve portion 206 so as to further assist in the removal of the upper sleeve portion 206 from the flower pot cover 10h.

The flower pot cover 10i is formed from a sheet of material 12i shown in FIG. 21. The sheet of material 12i is substantially identical in construction to the sheet of material 12h except that the sheet of material 12i is generally circular in shape; the sheet of material 12i is provided with a drawstring 226 extending circumferentially near an outer peripheral edge 70i thereof for closing an upper end 222a of the flower pot cover 10i formed from the sheet of material 12i; and the sheet of material 12i is further provided with a bonding material 228 extending about a peripheral portion 90i surrounding a basal layer 72i.
The crimped portion 224, which holds the flower pot cover 10i about the flower pot 15, may be formed by bringing together portions of the flower pot cover 10i near and about the bonding material 228 so that these portions of the flower pot cover 10i are disposed adjacent each other. The adjacent portions of the flower pot cover 10i are then bondingly connected via the bonding material 228 disposed thereon so as to form the crimped portion 224.
Other embodiments of the flower pot cover 12i are possible in which the sheet of material 12i or sheet extension portion 216i may be crimped and the present invention is not limited only to those described herein. For example, a band or a drawstring may be placed about a portion of the flower pot cover extending above the upper end of the flower pot with the band or drawstring engaging the portion of the flower pot cover extending above the flower pot so that the band forms the crimped portion 224 in the flower pot cover 10i. When the drawstring is utilized in the formation of the crimped portion, the drawstring must be drawn so as to form a plurality of overlapping folds in the flower pot cover. Once drawn, the drawstring may be secured by tying the drawstring into a bow, a knot or the like. Other versions of crimping are illustrated and described in the co-pending patent application entitled "Covering For Flower Pot and Floral Grouping", Ser. No. 08/037,067, filed by the Applicant on Mar. 25, 1993.
After the sheet extension portion 212i is formed into the upper sleeve portion 220i, the drawstring 226 may be drawn to close the upper end 222i of the upper sleeve portion 206i; and the upper end 222 may be securely closed by tying the drawstring 226 into a bow, a knot, or the like. Although it is preferred to close the upper end 222 by way of the first bonding material 217 or the drawstring 226, it should be understood that the upper end 222 may be closed by any means known in the art.

The sheet of material 12j is further provided with a tapered peripheral portion 90j which forms the flexible, tapered skirt portion 30j of the flower pot cover 10j when the sheet of material 12j is formed into the flower pot cover 10j. The tapered peripheral portion 90j surrounds the basal portion 37j and tapers outwardly from the basal periphery 80j of the basal portion 37j to the outer peripheral edge 70j of the sheet of material 12j. In other words, the peripheral portion 90j of the sheet of material 12j has a first thickness 234 extending along the basal periphery 80j greater than a second thickness 236 extending along the outer peripheral edge 70j of the sheets of material 12j.
The sheet of material 12j may be constructed of a single layer of material, as substantially shown in FIG. 25, or a plurality of layers of the same and/or different types of materials, as substantially shown in FIG. 26. The thickness of the sheet of material 12j and the basal portion 86j thereof may vary widely and any thickness of the sheet of material 12j and the basal portion 86j thereof may be utilized in accordance with the present invention so long as the sheet of material 12j is formable into the flower pot cover 10j, as described herein. When the sheet of material 12j is constructed of a plurality of layers of material, each layer of material may be connected to an adjacent layer of material via a bonding material.
It is to be understood that the flower pot cover 10j may be formed from any process formerly disclosed herein and from any process which is known in the art. For example, the flower pot cover 10j may be formed from an injection molding process, a blow molding process, a thermal forming process, an extrusion process, a vacuum process or combinations thereof. All of these processes are well known in the art. Therefore, no additional comments on molding the sheet of thermoplastic material 12j and forming the sheet of material 12j into the flower pot cover 10j are deemed necessary in order to teach a person skilled in the art how to manufacture the flower pot cover 10j.
