Definitions

  • the invention relates to a method for manufacturing a board drinking cup, forming the cup mantle by folding and seaming sheet-like cup blanks.
  • the invention also relates to the board drinking cup made by the method.
  • the invention relates specifically to disposable cups produced in mass production, which are equally suitable for holding cool drinks and hot drinks.
  • Disposable cups are generally made of cup paperboard, which is coated with a polymer coating at least on the side forming eventually the inner surface of the cup, in order to provide a waterproof cup. Cups may be or not equipped with a lug, and they have typically a conically expanding shape, allowing the cups to be nested with a view to packaging or to loading into automatic dispensers for dispensing one at a time.
  • Cups with lugs do not involve this problem, however, because of the limited bearing capacity of the lug, it is usable only in relatively small cups.
  • a cup with a lug also entails more intricate manufacture, and the foldable lug results in reduced comfort of use. Additionally, a disposable cup held by the lug may have poor stability when filled to the rim.
  • the method of the invention which provides the desired solution, is characterised by folding the cup blank at least partly double, so as to form in the cup both a mantle and an external collar directed downwardly from the cup mouth, with the folding point forming the cup mouth.
  • the collar provided by folding the blank forms a double wall construction in the area of the grip surface on the cup, this double wall construction basically providing double thermal insulation capacity of the wall construction. This already makes a cup containing a hot drink notably easier to hold. Additionally, the collar, which except for its folding point at the cup mouth, is detached from the cup mantle, leaves an inner air layer acting as supplementary thermal insulation between the collar and the mantle.
  • the folded collar is preferably formed as a ring encircling the cup and covering the portion of the outer surface of the cup determined by the ratio of the collar height to the cup mantle height.
  • the annular collar is simple in design, and also enhances the solidity of the cup structure markedly. This, in turn, allows a thinner cup board thus achieving material savings.
  • the material of the drink cup of the invention is appropriately a polymer-coated board, which is produced as a continuous web by a board machine and can be cut into blanks, from which cups can be manufactured by folding and seaming.
  • the collar of the invention is formed in the cup as the blank is folded.
  • the cup mantle is preferably conically expanding in the way disposable cups usually are, enabling the cups to be nested to save space.
  • the collar folded in the upwardly conically expanding cup becomes similarly conically downwardly expanding. Then an air space expanding downwardly from the cup mouth is formed between the collar and the cup mantle, this air space providing efficient insulation between the user's fingers and the mantle heated by the drink.
  • a downwardly expanding collar also hampers piling of cups minimally.
  • the lower edge of the collar can be equipped with an annular projection oriented inwardly towards the cup mantle.
  • the projection may consist of an enlargement of the cup material, having a stabilising effect on the cup as the user presses the collar against the cup mantle with his fingers. Additionally, the projection ensures a permanent air space acting as thermal insulation between the collar and the mantle. However, dimensioning of the projection should allow for a sufficient distance between the projection and the cup mantle in the normal cup state, for the projection not to interfere with piling of cups.
  • the enlargement acting as reinforcement at the lower edge of the collar may also project from the grip surface of the collar, enabling the user to get a better hold of the collar with his fingers. Regardless of its orientation, the enlargement may consist of a wind or an overlay in the cup material. It is also possible to form an annular enlargement acting as reinforcement at the folding point in the cup mouth. Such an enlargement of the cup mouth, which is known per se in previous collar-free cups, may also serve to generate the desired true oral sensation for the user drinking from the cup.
  • a suitable cup collar height may vary e.g. in the range 1 to 5 cm, depending basically on the cup size. In proportion to the cup height, the collar height may account for 20 to 80%, preferably about 25 to 50% of this height. However, in the extreme case, the collar height may be even equal to the cup height, and then the cup has a double wall throughout.
  • the board drinking cup of the invention which can be manufactured as described above, is characterised by the cup mantle being folded from the cup mouth downwardly to form a collar providing a grip surface outside the mantle.
  • the cup mantle may be conically expanding, allowing the cups to be piled with their mantle and collar portions partly nested.
  • FIGS. 1 to 3 show the folding and bending to form a cup out from a board cup blank step by step, with FIG. 1 showing the unfolded blank, FIG. 2 the blank, where the collar is folded, and FIG. 3 the blank after it has been seamed to the conically expanding shape of the cup,
  • FIG. 4 shows a drinking cup, in which the lower edge of the collar is equipped with an inner enlargement projecting towards the cup mantle,
  • FIG. 5 shows cups of FIG. 4 in nested state
  • FIG. 6 shows a drinking cup, in which the lower edge of the collar is equipped with a fold oriented inwardly towards the cup mantle,
  • FIG. 7 shows a drinking cup in which the lower edge of the cup is equipped with an outwardly oriented enlargement
  • FIG. 8 shows a drinking cup having enlargements both at the lower edge of the collar and at the mantle folding point in the cup mouth
  • FIG. 9 shows a drinking cup, in which the collar has a height equal to that of the cup.
  • FIGS. 1 to 3 The manner of manufacturing the cup illustrated in FIGS. 1 to 3 is particularly suitable for drinking cups made of board.
  • Manufacture starts from a sheet-like blank 1 cut out from a polymer-coated cup paperboard shown in FIG. 1 , the basic shape of the blank being part of a circular sector.
  • the vertical sides 2 of the blank 1 are aligned with the circular radii and the horizontal sides 3 with the curvature of a co-centric circle.
  • a broken line indicates a fold line 4 shaped as the curve of another co-centric circle, the blank 1 being divided into a mantle forming the sidewall of the cup and into an external annular collar by folding along the line 4 .
  • FIG. 2 shows the blank 1 after it has been divided into a part 5 forming the cup mantle and into a part 6 forming the collar by folding along the folding line 4 .
  • Folding is followed by bending to form the conically expanding cup shape of FIG. 3 and by heat sealing along the seaming line 7 formed by the overlapping vertical edges 2 of the blank.
  • the cup has been provided with a conically upwardly expanding mantle portion 5 and an annular collar 6 expanding similarly conically from the cup mouth 8 downwardly and encircling the mantle.
  • the cup blank folded and seamed as in FIG. 3 is equipped with a bottom attached by heat sealing.
  • the lower edge of the collar and/or the cup mouth may be equipped with an annular enlargement, such as a wind or an overlay. All of the cup working steps mentioned above can be implemented as serial production on a cup machine.
  • FIG. 4 is a simplified cross-sectional drawing of a board drinking cup 10 , which can be produced as in FIGS. 1 to 3 .
  • the cup 10 comprises an upwardly expanding mantle 5 shaped as truncated cone, which constitutes the side wall of the cup, a bottom 11 attached by heat sealing and a collar 6 expanding downwardly conically from the cup mouth 8 and having a height equal to about 1 ⁇ 4 of the cup height.
  • a wind 12 has been formed as reinforcement, projecting from the collar inwardly towards the cup mantle surface 5 .
  • Such a projection 12 prevents the collar 6 from being pressed against the cup mantle 5 by the user's fingers, thus maintaining a heat-insulating air slot between the collar and the mantle, preventing a hot drink from burning the user's fingers.
  • the drinking cups 10 of FIG. 3 can be piled as in FIG. 5 . Both the mantle portions 5 and the collars 6 of the cups are partly nested in piling. Given the fully symmetrical cups 10 , the pile will always be straight.
  • FIG. 6 shows an application of the drinking cup 10 of the invention, in which the lower edge of the collar 6 is equipped with a fold 13 encircling the collar annularly and oriented towards the cup mantle 5 .
  • the fold 13 has the same functions as the inner wind 12 within the cup collar 6 in FIG. 4 .
  • the fold 13 can be produced in the cup blank 1 in the first folding step, i.e. in connection with the folding of the collar 6 of FIG. 2 .
  • FIG. 7 shows a modification of the drinking cup 10 of FIG. 4 , in which the wind 12 at the lower edge of the collar 6 projects outwardly from the collar grip surface.
  • the wind 12 has a stiffening action on the collar 6 and makes it easier for the user to get a firm hold of the cup.
  • a combination of the application s of FIGS. 4, 6 and 7 is conceivable by providing the lower edge of the collar 6 projecting into both directions, i.e. both inwardly towards the cup mantle and outwardly from the collar.
  • the drinking cup 10 of FIG. 4 has been further modified by adding an annular wind 14 encircling the mouth at the cup mouth 8 as well.
  • Such an enlargement of the cup mouth 8 acts as additional reinforcement in the cup, while enhancing the comfort of use of the cup.
  • FIG. 9 shows an application of the drinking cup 10 of the invention, in which the collar 6 has been extended to cover the cup mantle 5 in its totality.
  • a collar 6 extending to the level of the cup bottom 11 enhances the stability of the cup placed on a base, and allows the cup mantle portion, i.e. the cup proper, to be narrower or more markedly tapered in shape than normally.
  • This solution may also be suitable for very shallow cups for structural and/or aesthetic reasons.
