Definitions

  • the invention relates to an apparatus and method for forming a paperboard receptacle from a paperboard blank in male and female dies.
  • Paperboard receptacles can be formed from blanks comprising a laminate of paperboard and a plastics film (e.g., a polyester such as polyethylene terepthalate). The portions of the blanks which will form the corners of the receptacle are scored to facilitate forming of the receptacle corners.
  • the primary problem of conventional systems for forming paperboard receptacles involves tearing or rupture of the paperboard at sharp bends between the bottom and side walls of the receptacle. These tears and ruptures can migrate to the scored areas at the corners where the blank is placed under maximum stress during the drawing process and where the blank has been weakened by the scoring.
  • the tearing and rupturing tendency is increased because the paperboard is not adequately plasticised to permit articles readily to be formed with sharp bends and corners without tearing, rupturing or cracking.
  • the friction or adhesion between the paperboard and forming dies causes a discontinuous, creeping drawing action, rather than a smooth, continuous drawing action. The discontinuous, creeping action tends to form wrinkles. and will not form smooth side wall surfaces.
  • Another problem associated with the use of conventional systems for forming paperboard receptacles involves separation of the plastics coating from the underlying paperboard.
  • the paperboard is passed through a water bath immediately prior to forming to wet the paperboard.
  • This additional wetting of the paperboard providing a moisture content in the paperboard of at least ten weight percent, to improve drawing causes wet adhesion problems which decrease the adhesion of the plastics film to the paperboard.
  • the pre-forming wetting operation of conventional systems is also disadvantageous in that it increases the dwell time required in the forming cycle in the dies, may necessitate an additional drying cycle and otherwise adversely affects the finished paperboard receptacle, particularly the printing thereof.
  • a laminated paperboard blank can be formed dry when sufficiently plasticised to permit the paperboard readily to be formed with sharp bends and corners and when sufficiently lubricated to provide a low coefficient of friction between the paperboard and the female die. If sufficient plasticising of the paperboard and sufficient lubrication between the paperboard and the die surfaces are provided, relatively dry laminated paperboard may be drawn in a manner resulting in an improved product and improved manufacturing procedures.
  • apparatus for forming a paperboard receptacle from a blank comprising a laminate of paperboard and a plastics film comprising mating male and female dies one of which is movable towards the other to draw the blank into the receptacle (known, for example, from DE-A-2 908 396), characterised by moisturizing means for injecting saturated steam into one of the dies to contact a paperboard blank positioned between the dies during drawing of the blank.
  • a method of forming a paperboard receptacle from a blank comprising a laminate of paperboard and a plastics film and having a bottom and side walls which comprises
  • Such apparatus and method can permit the receptacle readily to be formed by drawing without tearing, rupturing or cracking to produce an improved paperboard receptacle with straight sides, few vertical wrinkles, glossy and smooth side walls, flat bottoms and stiff and sturdy construction.
  • the saturated steam injected into the system by the moisturizing mechanism facilitates the forming process and enhances the product formed thereby.
  • the saturated steam plasticises the fibres of the paperboard quickly and locally at the maximum bend locations, enabling the paperboard to bend and to be moulded readily into articles having sharp bends and corners. Additionally, the saturated steam lubricates the sides of the paperboard receptacle and the walls of the die against which the receptacle walls are formed during the drawing process to enable the paperboard to be drawn in a smooth, continuous manner.
  • the plasticising and the lubrication provided by the injection of saturated steam into the system can eliminate tearing, rupturing and cracking at the junctures between the bottom and side walls of the paperboard receptacle and the migration of tearing, rupturing and cracking from such junctures to the scored corner areas of the paperboard receptacle.
  • the injection of saturated steam also eliminates the need for a pre-forming wetting operation resulting in the moisture content of the paperboard after forming being equal to or less than such moisture content before forming. This reduced moisture content in the formed receptacle makes it more rigid.
  • the saturated steam can be injected into a heated female die at a pressure less than about 103 x 10 3 Pa (15 p.s.i.), preferably 55 x 10 3 to 83 x 10 3 Pa (8 to 12 p.s.i.).
  • the heated female die heats the saturated steam to enhance plastizing of the paperboard.
  • the female die into which the saturated steam is injected can have a reciprocating plunger which engages a paperboard blank with a mating portion of the male die during drawing of the blank into the receptacle.
  • the steam can be injected into a lower cavity in the female die in which the reciprocating plunger is mounted, and the steam passes upward through the female die and through a generally annular outlet formed between the plunger and remainder of the female die to direct the steam against portions of the blank forming the receptacle side walls and the junctures of the receptacle bottom and side walls. In this manner, the steam is directed against those portions of the blank which are subjected to the maximum stress and are the greatest problem areas for tearing, rupturing and cracking.
  • the steam is preferably directed against the paperboard side of the paperboard-plastics film laminate.
  • plasticising means making paperboard more mouldable.
  • a paperboard receptacle 10 having a bottom wall 12 and side walls 14.
  • the bottom wall 12 is generally rectangular with rounded corners and has stiffening ribs 16 formed therein.
  • the side walls 14 extend upwardly and diverge from the periphery of the bottom wall 12 and are joined at the rounded corners.
  • a flange 18 extends about the periphery of the side walls 14 from the edges thereof remote from the bottom wall 12, and is generally parallel to the bottom wall 12.
  • Other receptacle configurations may be formed depending on the shape of the forming dies.
  • Apparatus 20 for forming the paperboard receptacle 10 is illustrated in Figures 2 and 3 in initial and intermediate stages of the drawing process, respectively, the apparatus 20 comprising mating male 22 and female 24 dies.
  • the male die 22 has a retaining ring 26 which extends about the periphery of the male die.
  • the centre portion 28 has a male plunger 29 movably mounted therein and spring biased towards an extended position illustrated in Figure 2.
  • the retaining ring 26 and the centre portion 28 are conventionally coupled by a suitable mechanism so to permit relative movement therebetween and are coupled to suitable driving mechanisms in conventional manners to enable the retaining ring and the centre portion to reciprocate relative to the female die 24.
  • the female die 24 comprises a base 30 and upstanding side walls 32.
  • the base 30 and the side walls 32 define an upper cavity 34 which conforms to the external configuration of the receptacle 10 and of the male die centre portion 28.
  • the inner surfaces of the side walls 32 extend upwardly and outwardly to form the diverging side walls 14 of the receptacle 10.
  • Top surfaces 36 of the side walls 32 surround the open top of the upper cavity 34, are angled downwardly and outwardly and are axially aligned with the retaining ring 26 to grip a blank 38 at a peripheral portion 40 thereof.
  • the base 30 comprises upper and lower sections 42, 44.
  • the upper section 42 is formed unitarily with the side walls 32.
  • the sections 42, 44 are secured in a suitable and conventional manner.
  • a lower cavity 46 is centrally located in the lower section 44.
  • the upper cavity 34 communicates with the lower cavity 46 through a constricted opening 48 provided in the base upper section 42.
  • a plunger 50 is movably mounted in the cavities 34, 46 for reciprocation between raised and lowered positions.
  • the plunger 50 comprises a generally cylindrical body 52 having a plate shaped head member 54 on its upper end and a stop 56 fixedly coupled at its lower end.
  • the plunger 50 reciprocates along an axis which is coaxial with the axes of the cavities 34, 46 and the opening 48 with the head member 54 located in the upper cavity 34 and with the stop 56 located in the lower cavity 46.
  • a spring 58 resiliently biases the plunger 50 toward its raised position.
  • Both the head member 54 and the stop 56 have dimensions in directions perpendicular to the axis of movement of the plunger 50 larger than corresponding dimensions of the opening 48 to retain the head member 54 and the stop 56 in the cavities 34, 46, respectively, and the body 52 within the opening 48.
  • the dimensions of the body 52 transverse to the plunger axis of movement are less than the corresponding dimensions of the opening 48 to provide an annular space therebetween.
  • the upper cavity 34 has a recess 60 formed in its lowermost portion surrounding the opening 48 to receive the head member 54.
  • the depth of the recess 60 is approximately equal to the thickness of the head member 54 to permit the upper surface of the head member 54 to be coplanar with the bottom surface 62 of the upper cavity 34 when the plunger 50 is fully retracted.
  • a transverse passageway 64 is formed in the base lower section 44 perpendicular to and in communication with the lower cavity 46.
  • the passageway 64 extends from the lower cavity 46 to the exterior of the base lower section 44.
  • a controlled pressure source of saturated steam 66 is in fluid communication with the passageway 64 through suitable conduits 68 and a suitable coupling 69. This arrangement enables steam from the steam source 66 to pass through the conduits 68, the coupling 69 and the passageway 64, and into the lower cavity 46 at a predetermined pressure. From the lower cavity 46, the steam travels about the plunger 50, through the opening 48 and into the upper cavity 34 where this steam contacts and moisturizes the paperboard blank and the die surfaces defining the cavity 34 as the blank is being drawn to form the receptacle 10.
  • Ridges 70 are provided on the upper surface of the head member 54. Grooves 72 are formed in the lower, blank contacting surface of the male plunger 29. These ridges and grooves mate and form the stiffening ribs 16 in the receptacle bottom wall 12.
  • Suitable heating means can be provided in the female die 24 to maintain its temperature in the range between 149°C and 204°C (300°F and 400°F), typically about 177°C (350°F).
  • a thermistor 74 may be suitably coupled to the female die 54 to measure and control the temperature of the female die.
  • the male and female dies are initially spaced apart a sufficient distance to permit a paper board blank 38 to be positioned therebetween.
  • a paper board blank 38 With paperboard which is coated with a plastics film (e.g., polyethylene terephthalate at 12.7 to 13.6 kg (28 to 30 pounds) for 279 M 2 (3000 square feet) of paperboard surface, the plastics film-paperboard laminate is placed between the dies 22, 24 with the plastics film facing the male die 22 and the paperboard layer facing the female die 24.
  • a plastics film e.g., polyethylene terephthalate at 12.7 to 13.6 kg (28 to 30 pounds) for 279 M 2 (3000 square feet
  • the male die 22 is lowered.
  • the blank 38 is engaged by the plunger 29 of the male die 22 before engagement with the retaining ring 28 permitting the peripheral portion 40 of the blank to roll into the female die 24. Subsequently, the peripheral portion 40 of the blank 38 is gripped between the top surfaces 36 of the female die 24 and the retaining ring 26 of the male die 22. A central portion 76 of the blank 38 (i.e., that portion forming the bottom wall 12) is then trapped between the male die centre portion 28 and the plunger 29 and the head member 54 of the female die 24. The engagement of the centre portion 28 and the plunger 29 with the head member 54 and the mating of the ridges 70 and the grooves 72 forms the stiffening ribs 16 in the blank 38.
  • the gripping of the blank 38 by the retaining ring 26 and the top surfaces 36 forms the peripheral flange 18 of the tray 10. Additionally, force applied by the ring 26 is limited such that the blank 38 is permitted to slip to a predetermined extent to place the blank 38 under tension during the drawing process.
  • the drawing of the blank to form the side walls 14 of the receptacle 10 is accomplished by the downward movement of the male die centre portion 28 and the plunger 29. This downward movement causes an intermediate portion 78 of the blank 38 located between the central portion 76 and the peripheral portion 40 to be stretched and moulded to form the side walls 14 of the receptacle 10.
  • the juncture between the central and intermediate portions 76, 78 of the blank 38 i.e., those portions forming the critical juncture between the bottom wall 12 and the side walls 14 of the receptacle 10) is exposed within the chamber 34 so as to permit direct exposure to the steam injected therein.
  • the steam is injected into the female die 24 at a pressure less than about 103 x 10 3 Pa (15 p.s.i.) so as not to disrupt the forming process.
  • the steam may be introduced at a pressure in the range between about 55 x 10 3 to 83 x 10 3 Pa (8 to 12 p.s.i.) and is preferably in the range of 69 x 10 3 to 83 x 10 3 Pa (10 to 12 p.s.i.).
  • the dies exert a total pressure of about 12,000 kg (12 tons) on the blank, with a final clinch of about 34.5 x 10 5 to 69 x 10 5 Pa (500 to 1000 p.s.i.).
  • the male die 22 is raised above the female die 24 to permit removal of the formed receptacle.
  • the plunger 50 will push the formed receptacle upwardly out of the upper cavity 34 under the bias of the spring 58.
  • the steam introduced into the female die 24 quickly plasticises the fibres of the paperboard so that they can bend and be moulded more easily.
  • the steam moisturises, thereby lubricating, the contacting surfaces of the paperboard blank 38 and of the female die 24 to permit a smooth and continuous drawing action. This lubrication also facilitates removal of the formed receptacle from the female die 24.
  • the temperature of the steam is raised further facilitating the forming process by increasing plasticisation of cellulose, by reducing crack formation and by enhancing the adhesion of the plastics film to the paperboard.
  • the moisturizing of the paperboard blank by injecting steam during the drawing process to plasticise and lubricate the blank permits the blank to be drawn with paperboard comprising as low as 3 weight percent water, as high as 7 weight percent water and normally between about 4 and 6 weight percent water, rather than with the 10 weight percent or more values presently employed in conventional drawing systems.
  • This reduction in the weight percentage of water in the paperboard increases the adhesion of the plastics film to the paperboard, increases the stiffness of the formed receptacle, reduces the dwell time of the blank in the dies, eliminates a drying cycle and reduces curl problems in the press feed.
  • the reduction in the weight percentage of water in the paperboard facilitates printing by permitting the use of colour offset printing systems which completely dry before forming of the paperboard, in lieu of the use of aniline press printing on wet paperboard.
  • the elimination of the conventional pre-forming wetting operation results in a clearer image by elimination of the smudging and smearing caused by such operation.
  • the receptacle formed therefrom and the method of forming are improved.
  • the sides of the receptacle can be formed straight and smooth without wrinkles in the paperboard or in the plastic film.
  • the adhesion of the plastics film can be improved and the tray can be stiffer and more rigid, have a flatter bottom and improved nesting and stacking characteristics.
  • the plasticising and lubrication provided by the steam injection can facilitate the formation of more complicated paperboard products by drawing.
