Description
- This application claims priority to co-pending U.S. Provisional Patent Application Ser. No. 60/598,550, filed on Aug. 2, 2004, by Fritz et al., entitled POLYMERIC CONTAINER, from which priority is claimed under 35 U.S.C. §119(e), the full disclosure of which, in its entirety, is hereby incorporated by reference.
- Paperboard containers have been in use for many years. Despite their popularity, paperboard containers are not well suited for containing items that require either a moisture vapor barrier or a gas barrier.
- Polymeric or plastic containers are better suited for containing substances that require a moisture vapor or gas barrier. Thermoforming such plastic containers requires the containers to have a tapered sidewall. In many instances, a true straight wall may be desired and is not achievable with thermoforming. Injection molding can be made straight wall, but is expensive and does not achieve high barrier requirements. Thermoforming requires an excessive amount of plastic material to accommodate the stretching and deformation of the plastic material during thermoforming. Moreover, the stretching or deformation of the plastic material during thermoforming prevents the printing of labels, data or images directly on the plastic material prior to the plastic material being shaped into a 3-dimensional container. Printing directly upon the plastic material after it has been shaped into a 3-dimensional container is costly and is limited in the quality of the image produced.

FIG. 17 is a top plan view of a machine for forming a cup according to one example embodiment. -
FIG. 1 is a sectional view of acontainer 10 according to one exemplary embodiment.Container 10 includesbottom 12 andsidewall 16.Bottom 12 includesfloor 18 andskirt 20. Skirt 20 projects fromfloor 18.Skirt 20 andfloor 18 are integrally formed as part of a single unitary body. In particular, bothfloor 18 andskirt 20 ofbottom 12 are substantially formed from at least one plastic or polymeric material. -
Sidewall 16 comprises a panel substantially formed from at least one polymeric material. For purposes of this disclosure, the phrase “formed substantially from at least one polymeric material” means that a member, panel or structure is formed from one or more layers of plastic or polymeric material such that main structural support or a majority of the thickness of the member is provided by the plastic or polymeric material. In particular embodiments, the plastic or polymeric material may have disbursed or impregnated filler materials. The one or more layers of plastic or polymeric materials may also include much thinner layers of non-polymeric or plastic materials wherein such layers have a de minimus or insubstantial thickness such that the non-polymeric layer or layers add little to the overall thickness of the member or do not substantially increase the rigidity or strength of the member. - As shown by
FIG. 1 ,sidewall 16 has a pair ofopposite ends Sidewall 16 further includes alower end 26 which wraps aboutedge 28 ofskirt 20. As a result,lower end 26 ofsidewall 16 cooperates withskirt 20 ofbottom 12 to form a 3-ply wall belowfloor 18. In the particular example shown,ends sidewall 16 such that overlapping portions ofends sidewall 16 is formed from appropriate materials. Examples of materials that may be used to provide an effective moisture vapor transfer barrier include polypropylene and low density polyethylene. An example of a material that may be used to provide an effective gas or oxygen transfer barrier is ethylene vinyl alcohol (EVOH). In a similar fashion,polymeric surfaces lower end 28 ofsidewall 16, as well assurfaces skirt 20 ofbottom 12 are heated so as tofuse skirt 20 tolower end 28 ofsidewall 16. The heating of such surfaces may be achieved by radiant heat, convection heat or by generating friction such as by ultrasonic welding. Skirt 20 and end 28 as well asends ends bottom 18 andsidewall 16 forms a substantially moisture impermeable and gas impermeable seal. - As further shown by
FIG. 1 ,sidewall 16 includes anupper end 44 which is curled or rolled for up to 270 degrees to provide themouth 46 ofcontainer 10 with a smooth surface. In the particular example shown,upper end 44 is curled utilizing a push in curl in whichends 44 are pushed towardsbottom 18 to form the noted curl. Alternatively,ends 44 may be formed by multiple push in curls or spin curls. -
Bottom 12 andsidewall 16, when joined, formcontainer 10 which hasinterior 48. Like containers formed from thermoformed or injection molded plastic,container 10 provides aninterior 48 well suited for containing liquids or other contents which require a moisture or gas impermeable barrier. Although not shown,container 10 may additionally be provided with a lid or cover. Unlike polymeric containers formed by thermoforming or injection molding,container 10 does not require stretching or deformation of thoseexterior portions 50 ofsidewall 16 that extend generally abovefloor 18. In addition, the fabrication ofcontainer 10 does not require thatportion 50 be subjected to extreme heat. As a result, at leastportions 50 ofsidewall 16 may be made from a thinner panel, requiring less material. In addition,portions 50 ofsidewall 16 may be configured so as to extend along axes orplanes 52 which are substantially perpendicular to theplane 54 offloor 18 ofbottom 12, providingcontainer 10 with a true straight sidewall. Moreover,portions 50 ofsidewall 16 may have text and/or images preprinted directly upon the surface ofsidewall 16 prior toends sidewall 16 being converted from a generally flat 2-dimensional panel to a 3-dimensional structure as part ofcontainer 10. Such printing may be achieved with less chance of printing becoming distorted during the formation ofcontainer 10. -
FIGS. 2-5 illustrate examples of materials from which bottom 12 andsidewall 16 may be formed.FIG. 2 is a top plan view of asheet 60 from which a sidewall blank 62 is formed.FIG. 3 is a sectional view of thesidewall 62. In one embodiment, sidewall blank 62 is cut fromsheet 60. According to one particular method, sidewall blank 62 is stamped fromsheet 60 and is generally 2-dimensional. As shown byFIG. 3 , sidewall blank 62 includes three substantiallycoextensive layers Layer 64 generally comprises a layer of a recycled polymer. In one embodiment,layer 64 comprises recycled polypropylene.Layer 64 is sandwiched betweenlayers layers -
Layer 66 comprises a layer substantially formed of a virgin polymer. In one embodiment,layer 66 is formed from virgin polypropylene. Becauselayer 66 is formed from virgin polypropylene, the surfaces oflayer 66 may be positioned alonginterior 48 of container 10 (shown inFIG. 1 ) where it may come in contact with the content ofcontainer 10 such as a food or beverage. -
Layer 68 comprises a layer of a virgin polymer. In the particular example shown,layer 68 comprises a layer of virgin polypropylene. Becauselayer 68 is formed from a virgin polymer,layer 68 may be located along an exterior ofsidewall 16 where it may come into contact with food or beverages, a person's hand or other surfaces for which contact withlayer 64 would be undesirable.Layer layer 64. - Because
sheet 60 and sidewall blank 62 formed from it includelayer 64 of a recycled polymer, sidewall blank 62 and the resultingcontainer 10 may be less expensively formed. In addition, sidewall blank 62 and the resultingcontainer 10 are more environmentally friendly in that at least a portion is formed utilizing the recycled polymer rather than being formed entirely from virgin polymer. The reduced cost and environmental benefit achieved by using a recycled polymer is further enhanced with the configuration ofcontainer 10. In particular, becausecontainer 10 is formed utilizing a two-piece construction, neither bottom 12 norsidewall 16 need to be substantially deformed or stretched as would otherwise be required in a thermoforming process. Because neither bottom 12 norsidewall 16 is substantially stretched or thinned during the formation ofcontainer 10, layers 66 and 68 of the virgin polymer may be made thinner with a lesser risk oflayer 64 becoming exposed. Becauselayers container 10. - In the particular example shown,
layer 64 has a minimum thickness of at least 0.005 inches and a maximum thickness of no greater than 0.040 inches.Layer 66 has a minimum thickness of at least about 0.001 inches and a maximum thickness of no greater than 0.040 inches.Layer 68 has a minimum thickness of at least about 0.001 inches and a maximum thickness of no greater 0.040 inches. In the particular example illustrated, layers 64, 66 and 68 are each additionally provided with a filler material which is impregnated or disbursed throughout the one or more polymers. In one embodiment, the filler material comprises talc. The talc filler material lessens the resiliency or memory of the polymericmaterial forming layers layers sidewall 16 may be formed from a single layer (such as formed out of a homopolymer material) of a polymeric material with or without a filler material disbursed throughout. -
FIG. 4 is a top plan view of asheet 80 from which a bottom blank 82 is formed.FIG. 5 is an enlarged sectional view of bottom blank 82.Sheet 80 is generally a planar 2-dimensional structure from whichbottom blank 82 is formed. In one embodiment, bottom blank 82 is cut fromsheet 80. In the particular example shown, bottom blank 82 is stamped fromsheet 80. - As shown by
FIG. 5 , bottom blank 82 includes three substantiallycoextensive layers sheet 80. According to one particular method bottom blank 82 is stamped fromsheet 80 and is generally 2-dimensional. As shown byFIG. 5 , bottom blank 82 includes three substantiallycoextensive layers Layer 84 generally comprises a layer of a recycled polymer. In one embodiment,layer 84 comprises recycled polypropylene.Layer 84 is sandwiched betweenlayers layers -
Layer 86 comprises a layer substantially formed of a virgin polymer. In one embodiment,layer 86 is formed from virgin polypropylene. Becauselayer 66 is formed from virgin polypropylene, the surfaces oflayer 66 may be positioned alonginterior 48 of container 10 (shown inFIG. 1 ) where it may come in contact with the content ofcontainer 10 such as a food or beverage. -
Layer 88 comprises a layer of a virgin polymer. In the particular example shown,layer 88 comprises a layer of virgin polypropylene. Becauselayer 88 is formed from a virgin polymer,layer 88 may be located along an exterior ofsidewall 16 where it may come into contact with food or beverages, a person's hand or other surfaces for which contact withlayer 84 would be undesirable.Layer layer 84. - Because
sheet 80 and sidewall blank 62 formed from it includelayer 84 of a recycled polymer, sidewall blank 62 and the resultingcontainer 10 may be less expensively formed. In addition, sidewall blank 62 and the resultingcontainer 10 are more environmentally friendly in that at least a portion is formed utilizing the recycled polymer rather than being formed entirely from virgin polymer. The reduced cost and environmental benefit achieved by using a recycled polymer is further enhanced with the configuration ofcontainer 10. In particular, becausecontainer 10 is formed utilizing a two-piece construction, neither bottom 12 norsidewall 16 need to be substantially deformed or stretched as would otherwise be required in a thermoforming process. Becausesidewall 16 is not substantially stretched or thinned during the formation ofcontainer 10, layers 86 and 88 of the virgin polymer may be made thinner with a lesser risk oflayer 84 becoming exposed. Becauselayers container 10. - In the particular example shown,
layer 84 has a minimum thickness of at least 0.005 inches and a maximum thickness of no greater than 0.040 inches.Layer 86 has a minimum thickness of at least about 0.001 inches and a maximum thickness of no greater than 0.040 inches.Layer 88 has a minimum thickness of at least about 0.001 inches and a maximum thickness of no greater 0.040 inches. In the particular example illustrated, layers 84, 86 and 88 are each additionally provided with a filler material which is impregnated or disbursed throughout the one or more polymers. In one embodiment, the filler material comprises talc. The talc filler material lessens the resiliency or memory of the polymericmaterial forming layers layers sidewall 16 may be formed from a single layer (such as formed out of a homopolymer material) of a polymeric material with or without a filler material disbursed throughout. - As further shown by
FIGS. 4 and 5 , bottom blank 82 additionally includes acircumferential score 90.Score 90 extends partly into or partly through the thickness of bottom blank 82.Circumferential score 90 facilitates the bending or other deformation of a perimeter portion of blank 82 alongscore 90 to formfloor 18 andskirt 20. Althoughscore 90 is illustrated as being continuous, score 90 may alternatively intermittently extend circumferentially along and substantially parallel to an edge perimeter of bottom blank 82. Although the edge perimeter of bottom blank 82 as well asscore 90 are illustrated as being substantially circular, bottom blank 82 and score 90 may have other shapes and configurations depending upon the desired shape ofcontainer 10. For example, bottom 82 may alternatively be square or rectangular in shape with generally rounded corners. In other embodiments, bottom blank 82 may be oval. In such embodiments, the joining ofends FIG. 1 ) and the joining oflower end 28 ofsidewall 16 to bottom blank 82 would result in a container having a non-circular or non-cylindrical interior. - The formation of
container 10 is generally as follows. Initially, sidewall blank 62 and bottom blank 82 are formed fromsheets bottom link 82 is separated fromsheet 80, scores 90 are formed which extend betweenfloor 18 andskirt 20.Skirt 20 is bent or otherwise deformed relative tofloor 18.Skirt 20 is joined tolower end 28 of sidewall blank 62 while ends 22 and 24 of sidewall blank 62 are joined to one another. In the embodiment in whichsheet 60 andsheet 80 include a layer of recycled of polymer and an adjacent layer of virgin polymer, sidewall blank 62 and bottom blank 82 are positioned so as to position the layer of virgin polymer adjacent to an interior of the resulting container. Printing upon sidewall blank 62 is done before sidewall blank 62 is joined to bottom blank 82 and while sidewall blank 62 is in a generally 2-dimensional form. In the particular example shown,lower end 28 and/orskirt 20 are heated, ultrasonically welded, adhered with a hot melt or glue or otherwise treated so as to fuse, weld or otherwise joinlower end 28 to skirt 20. In one particular embodiment,lower end 28 is wrapped aboutskirt 20. Although sidewall blank 62 is configured so as to form a substantially straight sidewall which extends along axes or in an arcuate plane substantially perpendicular to the plane in whichfloor 18 extends, sidewall blank 62 may alternatively be configured so as to form an outwardly tapered sidewall with respect to the plane in whichfloor 18 extends. -
FIG. 6 is a sectional view ofcontainer 110, another embodiment ofcontainer 10 shown inFIG. 1 .Container 110 is similar tocontainer 10 except thatlower end 26 ofsidewall 16 does not wrap aboutend 28 ofskirt 20 ofbottom 12. Rather, surface 38 ofskirt 20 andsurface 32 oflower end 26 ofsidewall 16 are sealed to one another. In one embodiment, the sealing is achieved by melting the polymer material ofsurfaces - In contrast to paperboard, plastic or polymeric materials have a much greater elasticity or shape memory. Moreover, plastic or polymeric material does not compress like paperboard. As a result, during bending of
skirt 20 away fromfloor 18, portions ofskirt 20 may overlap one another and build up. With paperboard material, the paper compresses. Due to its shape, memory or elasticity, the polymeric material ofskirt 20 does not easily compress which may result in the formation of gaps betweensidewalls 16 andskirt 20. These gaps present leakage issues and forming issues. -
FIGS. 7-9 illustrate techniques for treatingskirt 20 of bottom 12 (or of bottom blank 82) to lessen the resiliency or shape memory ofskirt 20 and to reduce the likelihood of a potential leak causing gaps betweenskirt 20 and sidewall 16 (or sidewall blank 62).FIG. 7 is a top plan view of bottom blank 182 formed fromsheet 80 described above with respect toFIG. 4 . As noted above,sheet 80 includes threelayers FIG. 5 ). In other embodiments,sheet 80 may alternatively comprise a single of polymeric material or a homopolymer plastic sheet. One ormore layers sidewall 16, bottom 12 (formed from bottom blank 82 or blank 182) may be opaque, translucent or clear. - Bottom blank 182 has a generally
circular perimeter edge 192 and an inwardly spacedcircumferential score 190.Score 190 extends partially into the thickness or caliber of bottom blank 182 to separate bottom blank 182 intofloor 18 andskirt 20. In one particular embodiment, score 190 has a depth of one-half the thickness or caliber of bottom blank 182. In the particular embodiment, score 190 continuously extends circumferentially about a center of bottom blank 182 and is inwardly spaced fromouter edge 192 by a minimum distance of at least 0.100 inches. In other embodiments, bothouter edge 192 and score 190 may have shapes other than circles. For exampleouter edge 192 and score 190 may alternatively be oval, square or rectangular. In square and rectangular embodiments, the corners are rounded. - As shown by
FIG. 7 ,skirt 20 of bottom blank 182 is additionally treated at a plurality of spaced locations to weaken the resiliency of one or more polymeric materials from whichbottom blank 182 is formed. In the embodiment shown inFIG. 7 ,skirt 20 is treated by scoring. In particular,skirt 20 includes a plurality of uniformly or equally spaced scores 196.Scores 196 have a depth of at least one-third of the thickness or caliber of bottom blank 182. In the particular example shown, bottom blank 182 has a caliber thickness of 0.020 inches and scores have a depth of approximately 0.010 inches.Scores 196 extend fromedge 192 tocircumferential score 190. In the particular example shown, eachscore 190 has a length of at least 0.100 inches and nominally of about 0.375 inches.Scores 196 weaken the resilient nature or shape memory of the polymeric material ofskirt 20 to facilitate bending ofskirt 20 relative tofloor 18 and to facilitate better securement ofskirt 20 tosidewall 16. -
FIG. 8 is a top plan view illustrating bottom blank 282 formed fromsheet 80. Bottom blank 282 is similar to bottom blank 182 except thatskirt 20 of bottom blank 282 is treated at a plurality of spaced locations withslits 296 in lieu ofscores 196.Slits 296 comprise cuts which extend inwardly fromouter edge 192 and which extend completely through the thickness or caliber of bottom blank 282.Slits 296 extend inwardly fromouter edge 192 and have terminal ends 298 spaced fromcircumferential score 190.Slits 296 have a length such that terminal ends 298 are spaced fromcircumferential score 190 by at least 0.1 inches. In one embodiment, slits 296 have a length of approximately two-thirds of the bottom depth BD (FIG. 1 ). In other embodiments, slits 282 may have other lengths such that ends 298 are spaced fromscore 190 by other distances. A number ofslits 296 as well as the uniform spacing ofslits 296 is determined based upon the radial difference betweenouter edge 192 andcircumferential score 190. In the particular example shown, slits 296 are evenly spaced from one another about the circumference. -
Slits 296 weaken the resilient nature or shape of memory ofskirt 20 to facilitate bending or deformation ofskirt 20 relative tofloor 18.Slits 296 further facilitate the joining ofskirts 20 tosidewall 16. As compared toscores 196,slits 296 are relatively better at weakening the resilient nature ofskirt 20, enabling easier and more reliable joining ofskirt 20 to sidewall 16, improved heating and reducing the potential for leakage between bottom 12 andsidewall 16. -
FIG. 9 is a top plan view illustrating bottom blank 382 formed fromsheet 80. Bottom blank 382 is substantially similar to bottom blank 182 except thatskirt 20 of bottom blank 382 is treated at a plurality of spaced locations to weaken the shape memory or resilient nature of the polymeric material ofskirt 20 by notching in lieu of scoring. In particular,skirt 20 includes a plurality of inwardly extendingnotches 396.Notches 396 are different thanscores 196 andslits 296 in thatnotches 396 are formed by removal of material fromskirt 20. Because material is removed,notches 396 better minimize overlapping or pleating ofskirt 20 when it is bent or deformed relative tofloor 18 as compared toscores 196 or slits 296. By reducing pleating ofskirt 20,notches 396 reduce the likelihood of leaks occurring betweenskirt 20 and sidewall 16 (shown inFIG. 1 ).Notches 396 further enable bottom blank 382 to be more easily formed intofloor 12 and joined to sidewall 16. - As shown by
FIG. 9 ,notches 396 are uniformly spaced about the entirety ofskirt 20. The spacing and the quantity ofnotches 396 is determined based upon the radial distance betweenouter edge 192 and score 190. In the particular example shown,notches 396 have a radial length of approximately two-thirds of the bottom depth BD (FIG. 1 ).Notches 396 extend inwardly fromouter edge 192 towardsscore 190. In the particular example shown,notches 192 are generally V-shaped. Becausenotches 396 are V-shaped,notches 396 better reduce shape memory ofskirt 20. In other embodiments,notches 396 may have other shapes. In the particular example shown,notches 396 haveend points 398 which terminate prior to reachingscore 190. In the particular example shown,end points 398 are spaced fromscore 190 by a minimum radial distance of 0.1 inches and a maximum radial distance of 0.125 inches. In the embodiment shown, eachnotch 396 has a radial depth of about 0.02 inches and 0.03 inches. - Overall,
containers containers containers Containers sidewall 16 abovefloor 18 whilesidewall 16 is in a 2-dimensional state with less distortion during the completion of the formation of the container.Containers Containers sidewall 16. - Although
containers mouths 46 which have the same diameter as theopposite floor 18,containers containers sidewalls 16.FIGS. 10-13 illustratecontainer 410, another embodiment of container 10 (shown inFIG. 1 ).Container 410 is substantially similar tocontainer 10 except thatcontainer 410 has outwardly taperingsidewalls 416. Those remaining components ofcontainer 410 which correspond tocontainer 10 are numbered similarly.FIG. 13 illustratessidewall 416 after it has been cut or formed from sheet 60 (described above).Sidewall 416 is joined to bottom 12 in a similar manner to that of the joining ofsidewall 16 tobottom 12. - Although
containers sidewall 16 and bottom 12,containers FIGS. 13-16 illustratecontainer 510, another embodiment ofcontainer 10.Container 510 is similar tocontainer 410 except thatcontainer 510 includes aperforated bottom 512 andsidewall 516 in lieu of bottom 12 andsidewall 416 ofcontainer 410. According to one embodiment,bottom 512 is formed fromsheet 80 described above. In other embodiments, bottom 512 may be formed from sheets of other materials. As compared to bottom 12,bottom 512 additionally includes cutouts ornotches 596 andperforations 598.Notches 596 minimize overlapping or pleating ofskirt 20 when it is bent or deformed relative tofloor 18. As a result, cutouts 96 reduce the likelihood of leaks occurring betweenskirt 20 andsidewall 516.Cutouts 596 further enable bottom blank 582 to be more easily formed intobottom 512 and joined to sidewall 516. -
Perforations 598 constitute openings extending throughfloor 18 ofbottom 512.Perforations 598 facilitate the escape of moisture from the interior ofcontainer 510 and the in-flow of external air intocontainer 510. As a result,container 510 is well suited for containing soil, plants or other similar contents. -
Sidewall 516 is similar tosidewall 416 except thatsidewall 516 includesnotches 602.Notches 602 have a sufficient depth or dimension so as to facilitate wrapping ofsidewall 516 and bending of the lower end ofsidewall 16 aboutskirt 20 ofbottom 512 while minimizing overlapping of portions ofsidewall 16 to reduce leakage potential. In other embodiments,notches 602 may be omitted. -
Containers FIG. 17 illustrates a floor plan of one example of amachine 610 configured to formcontainer 10,container 410 orcontainer 510. In particular, the machine shown is configured to perform the above-described steps.Machine 610 generally includesmandrel turret 612, rimmingturret 614,transfer turret 616,bottom maker 618,bottom preheat station 620,sidewall heater 622, blank orroll feed 624,bottom heat station 626, bottom in-curl station 628, rimmingstations 630 andcup discharge 640.Bottom maker 618 forms bottom 12. In one embodiment,bottom maker 618 additionally includes hole puncher 632 for forming perforations 598 (shown inFIG. 16 ) when a cup such ascup 510 is being formed. In other embodiments, hole puncher 632 may be omitted. -
Bottoms 12 formed bybottom maker 16 are carried bymandrel turret 612 to preheatstation 620 wherebottoms 12 are preheated prior to bonding of sidewall such assidewall 16 thereto. Sidewalls, such assidewalls 16, are formed by blank orfeed roll 616 supplying sidewall blanks to transferturret 624 which transfers the sidewalls tosidewall heater 622 and subsequently into position with respect tobottoms 12, wheresidewalls 16 are wrapped aboutbottoms 12 and the sides ofsidewall 16 are bonded to one another.
