Definitions

  • This invention relates to cup holders and in particular relates to a sleeve adapted to receive a cup in one position and foldable in another position.
  • the invention also relates to the method of producing the holder.
  • Disposable paper board cups are routinely used in fast food and restaurants to contain hot drinks. Such cups are generally of standardized size normally frusto- conical or tapered. Such cups are generally thin walled and may be difficult to handle particularly when the cups include hot coffee, tea, soup or the like.
  • cold drinks may also be served in standardized frusto-conical cups and may also be difficult to hold in view of the cold temperature.
  • Such prior art cups may be comprised of very thin plastic having little strength.
  • U.S. Patent No. 5, 205,473 relates to a corrugated beverage container and holders which provide fluted structures for containing insulating air.
  • U.S. Patent No. 5,425,497 also relates to a cup holder in the form of a sheet with distal ends.
  • a web is formed in one of the ends, and a corresponding slot is formed at the other end such that the ends interlock.
  • the cup holder is assembled by rolling the sheet and interlocking the ends.
  • the sheet can be an elongate band of pressed material preferably pressed paper pulp as preferably formed with multiple nubbins and depressions.
  • U.S. Patent No. 5,826,786 which relates to a cup holder sleeve formed in pre-assembled, flat-folded form by die cutting a flat elongated band from blank stock material so as to have top and bottom edges concentric to and parallel with each other, fold lines scored into the band at spaced apart positions tapering toward each other, and side edges at opposite ends of the band.
  • U.S. Patent No. 5,842,633 relates to a sleeve provided for a frusto- conical beverage cup, configured to fit around the outside of the cup, thus protecting the fingers of the user from excessive temperatures in the case of hot drink, and to provide a measure of insulation for the contents of the cup.
  • It is an aspect of this invention to provide a holder for a cup comprising a foamed plastic sleeve having an open top and bottom for receiving said cup.
  • It is a further a spect of this invention to provide a holder for a tapered cup comprising an extruded foamed plastic sheet having spaced substantially concentric curved top and bottom and two opposite ends; said ends are overlapping and bonded to each other to define a sleeve; said extruded foam plastic sheet been pliable without breaking.
  • It is yet another aspect of this invention to provide a method of manufacturing a foamed polystyrene sleeve for a cup comprising extruding a sheet of foamed polystyrene; cutting said sheet to form spaced substantially concentric curved top and bottom and two opposite ends; forming at least two fold lines and a plurality of ribs to said cut sheet; folding said formed sheet so as to overlap and bond said ends together.
  • An object o f o ne a spect of the p resent i nvention is to provide a n improved insulating sleeve.
  • Figure 1 is a perspective view of the cup holder or sleeve containing a cup.
  • Fig. 2 is a partial top plan view of an extruded sheet of foamed polystyrene.
  • Fig. 3 is a top plan view showing a cut and formed sheet.
  • Fig. 4 is a top plan view of a foamed extruded polystyrene sheet which has been cut and formed.
  • Fig. 5 is a cross-sectional view along the lines 5-5 of Fig. 4.
  • Fig. 6 illustrates a stacked array of cut formed sheets.
  • Fig. 7 illustrates the folding and gluing step.
  • Fig. 8 is a perspective view of the cup holder.
  • Fig. 9 is a top plan view of Fig. 8.
  • Fig. 10 is another embodiment of the invention.
  • Fig. 11 is another embodiment of the invention.
  • Fig. 1 illustrates the cup holder or sleeve 2 in combination with a cup 4 which may have a lid 6.
  • the cup 4 can be comprised of a variety of materials but generally consists of a paper cup which is well known to those persons skilled in the art having little insulating value.
  • the cup 4 is generally frusto-conical or tapered and is concentric about axis 8.
  • Fig. 8 generally illustrates the holder or sleeve 2 or cup which is comprised of a foamed plastic having an open top 10 and open bottom 12.
  • foamed polystyrene is not pliable, namely, that it will break when attempting to bend a flat sheet into a circular configuration.
  • foamed plastic has been found to be pliable when adding a plurality of depressions.
  • foamed polystyrene More specifically by forming ribs into the foamed polystyrene it has been found that a pliable structure which can be manipulated into a sleeve without breakage. Alternatively in another embodiment, it is also been found that if the thickness of foamed polystyrene is selected to be thin enough to be pliable so as not to break when configured into a circular sleeve.
  • a cup holder can be constructed, as described below.
  • the embodiment of the cup holder shown in Fig. 8 includes a plurality of ribs 14 which are disposed to extend between the open top 10 and open bottom 12 as shown. More particularly the plurality of ribs 14 may be disposed substantially in the same direction as the axis 8.
  • the embodiment shown in Fig. 8 can be constructed from a sheet of extruded foamed polystyrene as shown in Fig. 2.
  • the sheet of extruded foamed polystyrene is extruded from the extruder (not shown) in the direction D of the extruded path.
  • the extruded foam sheet may exit in the form of a continuous web which can by standard practise, be aged for three or four days to permit dissipation of foamed gases and the like.
  • the sheets of foamed polystyrene can be delivered to a cutting and thermo forming station (not shown) so as to cut the sheet 20 to produce a cut sheet having spaced substantially concentric curved top and bottom 12 and two opposite ends 22 and 24.
  • the opposite ends 22 and 24 are adapted to be overlapped and bonded to one another so as to define the sleeve shown in Fig. 8.
  • the sheet 20 of foamed polystyrene is embossed to produce a plurality of depressions (best seen in Fig. 5) to define a plurality of ribs 14.
  • the sheet 20 can be embossed to form any textured surface such as stipples, waves or other patterns so long as the thickness of the foam sheet is "squeezed". It is believed that this forming or squeezing stage compresses the closed cell structure of the foamed polystyrene so as to improve its pliability.
  • foamed polystyrene is a naturally good insulating material and will insulate the user's fingers from the hot beverages contained in the cup 4.
  • cup holders 2 could be stacked one inside the other for shipment at least two fold lines 30, as seen in Fig. 3 are applied during the thermo forming stage so as to permit the sleeve to be collapsed into a flat position for storing and transporting and be thereafter opened to defined a substantially frusto-conical sleeve having an open top 10 and bottom 12 adapted to receive the cup in the open position.
  • ribs shown in Fig. 1 are formed on the exterior surface of the sleeve 2, but could just as easily be formed on the interior surface of the sleeve 2 particularly when used to hold cold drinks which tend to form condensate on the outside of the cup to permit drainage by gravity without wetting the fingers of the user.
  • the ribs 14 are disposed on the inside of the sleeve to allow condensation to run off a cup filled with cold drinks.
  • Fig. 6 illustrates a stacked array of cut formed sheets showing the fold lines 30.
  • Fig. 6 illustrates a stacked array of cut formed sheets showing the fold lines 30.
  • two pairs of fold lines 30 are provided.
  • Each cut sheet is then advanced to the folding and adhesive station shown in Fig. 7 whereby the cut sheets 20 are sequentially advanced by any number of means including rollers (not shown) so as to upturn the edges 22 and 24 towards one another so as to thereby apply a suitable adhesive such as a hot melt adhesive to at least one of the overlapping edges 22 and 24 so that by the time the folded sleeve reaches the end of the folding station as shown in Fig. 7 the sleeve is substantially flat as shown and glued together. Any means of gluing or adhesive can be used.
  • indicia 40 may be added, as seen in Fig. 8 to include a company logo, trademark or the like so as to improve the appearance of the cup holder.
  • Fig. 11 shows another embodiment of the invention whereby the sleeve is comprised of a loop of cut foamed polystyrene which is adhesively bonded as previously described to form a closed loop sleeve.
  • the thickness of the foamed polystyrene it has been found that sleeves are pliable or bendable without breaking. In one embodiment of the invention it has been found that if the thickness of foamed polystyrene is selected to be up to approximately 25 thousandths of an inch a plastic sleeve can be constructed. However the invention should not be limited to up to 25 thousandths of an inch as greater thicknesses could be used within the spirit of the invention.
  • the sleeves can include a plurality of fold lines as previously described and flattened again as previously described.
  • the depressions or ribs have been removed.
  • the ribs may be added.
  • any other texture apart from ribs such as stippling or the like which have embossed so as to improve the pliability characteristics of polystyrene can also be used.
  • the invention described herein illustrates a method of manufacturing a foamed polystyrene sleeve for a cup comprising:
  • the spacing of the ribs are accurately calculated so that even though the ribs 14 fan out as shown in Fig. 3 i.e. are placed radially substantially parallel to one another once the sleeve is formed the ribs tend to be disposed along the length of the cup 4. Furthermore the polystyrene has an improved co-efficient of friction as compared to a typically prior art sleeves so as to improve the gripping characteristics.
  • the sleeve adds structural strength to a flimsy cup as manufacturers of cups try to reduce their costs.
