Definitions

  • the invention concerns eco-friendly products used for beverages.
  • Such known products are usually made of paper mixed with plastic (polymers).
  • plastic polymers
  • cups, containers, utensils mainly for liquids that are consumed while the lid is placed on the container.
  • the terms cup, container or utensil are used for a container with an opening that may be closed by a lid.
  • EP0459017 describes a closing lid made of cardboard for cans or can-like containers, with a circumferential stabilizing ring reinforcing the edge of a circumferential flange of the lid.
  • the stabilizing ring is fixed on the inside and/or the outside of the circumferential flange by gluing and/or welding.
  • EP3943409 describes a paper lid for a container.
  • the lid comprises a central and flat lid panel and an outer fitting flange with two legs to interlock with an upper rim of the container.
  • the one leg has an inwardly folded end portion in abutment with an inner surface of the unfolded portion and connected to the same
  • EP3403944 describes a lid made from a paper- or a cardboard material for closing a container.
  • the lid comprises a top wall, which covers the opening of the container and a sidewall directed at an angle relative to the top wall.
  • One end of the sidewall with a rolled edge can engage with the top end of the container.
  • the object of the invention is an eco-friendly lid for a cup. Another object of the invention is a cup with a lid for beverage consumption. Another object of the invention is a method of manufacture of a lid for a cup, container or utensil.
  • a lid of a cup has a central wall with a perimeter and a skirt extending along the perimeter.
  • the skirt extends laterally and at an angle to the central wall and has an outer wall and a fold.
  • the fold extends from the outer wall towards the central wall.
  • the outer wall and the fold are rotatable around an edge provided on the skirt, where they converge, to change the angle between them.
  • the lid is formed from a single piece of paperboard of recyclable material.
  • the geometry of the lid offers excellent properties and hinders unwished spillage of the liquid that is contained in the cup that is closed by the lid.
  • the configuration of the lid does not require a particular geometry of the lip of the cup or container and is appropriate to co-operate with various cups. At least towards the edge, the fold is flat, i.e. it is not rolled as it is in some known lids.
  • the design of the lid makes it easy to store multiple lids in a relatively small space.
  • the geometry of a lid according to the invention is effective, even if the paperboard does not contain any substance that would have had rendered the lid a single-use plastic product according to the EU Directive EU 2019/904 on the reduction of the impact of certain plastic products on the environment that came into force on 3 July 2021 and the related Commission guidelines on single-use plastic products: 2021/C 216/01.
  • the paperboard is multi-ply, preferably with three plies.
  • the plies of the paperboard include cellulose fibers and may also include other substances such as minerals, lignine, binding agent or any other substances, which do not render the lid single-use plastic product.
  • the layered structure of the paper enhances the technically acceptable and stable forming process that reduces shape memory effects.
  • the paperboard may have constant thickness.
  • the fold may have a flap with a free end that may rotate about a hinge line other than the edge of the skirt, which is provided on the fold.
  • the rotation of the flap further facilitates the locking of the lid to a cup and the use of the lid with cups having various shapes.
  • the outer wall has a lower portion that is disposed radially and axially from the central wall and is connected to the fold at the edge of the skirt.
  • the outer wall may have an upper portion, a lower portion and a shoulder therebetween.
  • the lower portion is disposed radially and axially from the central wall and is connected to the fold at the edge of the skirt.
  • the upper portion extends and the shoulder is disposed at a distance axially from the central wall. The widening of the skirt away from the central wall further facilitates the relative rotation of the fold and the outer wall and the use of the lid with cups of different dimensions and configurations of the edge of their opening.
  • the central wall is also circular.
  • the skirt has a circular cross-section and if the outer wall has an upper portion and a lower portion, the diameter the cross-section of the former is larger than the diameter of the cross-section of the latter.
  • the lid may be provided in the central wall with a hole for the flow of liquid or for placing a straw.
  • the outer wall has a tip that projects from the central wall and is opposite to the edge of the skirt. This configuration offers further stability and robustness to the lid. The height of the tip is minimal.
  • Some embodiments have creases scattered over the entire surface of the outer wall and the fold.
  • the creases that are scattered on the surface of the fold may be more dense that the creases that are scattered on the surface of the outer wall.
  • the creases, which enhance stability of the lid, are randomly scattered, extend radially etc..
  • the cup may feature a lip around an opening.
  • the lid traps a lip of a cup or container between the skirt and the central wall.
  • the configuration of a lid according to the invention renders the lid versatile, since it allows the closure of cups with various shapes of lips, for example lips with circular, oval or other cross-section, channel type lips etc.
  • Figure 1 shows a lid (10) formed from a sheet (33) of paperboard, placed on a cup (20).
  • the cup (20) - see also Figure 5 - has a base (26) and a lateral side jacket (24). At the free edge (27) of the side jacket (24), a lip (22) protrudes towards the outer space of the cup (20) defining an opening of the cup (20).
  • the protruding lip (22) may have any form of cross-section, e.g. circular, oval, triangular, trapezoidal, channel-like or other. In some examples the lip (22) is formed by rolling the edge of the opening.
  • Figure 3 shows the lid (10) with a central wall (13) and a skirt (16) at an angle with respect to the central wall (13). In this condition, the angle may be equal or about equal to 90 deg.
  • the skirt (16) extends along the entire perimeter (18) of the central wall (13).
  • the central wall (13) has an annular portion and a central portion that lie parallel to each other with a slight offset.
  • the skirt (16) starts from the perimeter (18) of the central wall (13). As shown in Figures 4 and 6 , the skirt (16) folds and forms an outer wall (12) and an inner flat wall, i.e. the fold (19), rather than rolled, which is observed in known lids.
  • the fold (19) folds to the interior of the space defined by the skirt (16), extends to the central wall (13) and ends at a short distance from it. In the area where the sheet (33) is folded, there is a pivoting edge (17), around which the outer wall (12) and the fold (19) rotate around each other.
  • the outer wall (12) has two end portions (121), (123) and a midportion, i.e. shoulder (122).
  • the one of the two end portions (121), (123) is designated as upper portion (121) and projects from the central wall (13).
  • the other of the two end portions (121), (123) is designated as lower portion (123) and is connected directly with the fold (19).
  • the shoulder (122) is in between and connects the two end portions (121), (123).
  • the shoulder (122) is at a distance from the central wall.
  • the lower portion (123) extends radially outwards from the upper portion (121), i.e. the projection of the upper portion (121) on a plane that is parallel to the central wall (13) lies within the projection of the lower portion (123) on the same plane, with the projection of the shoulder (122) lying in-between.
  • the fold (19) has three portions disposed in a series: a pivoting portion (193), a connector (192) and a flap (191), whereby the pivoting portion (193) is connected to the lower portion (123), the flap (191) has a free edge and the connector (192) is between the pivoting portion (193) and the flap (191).
  • the connector (192) may be a hinge line between the pivoting portion (193) and the flap (191).
  • the flap (191) has a length that is smaller than the length of the corresponding upper portion of the outer wall (121).
  • the length of the outer wall, the fold and the corresponding portions are measured along a line that is normal to the central wall (13), which coincides with the direction of the axis of the cup (20) when the lid (10) is placed on the cup (20).
  • Figure 8 shows the exploded view of the skirt (16), where the width of the outer wall (12) and the fold (19) is denoted by the letter « ⁇ ».
  • the width of the skirt (16), i.e. the outer wall (12) and the fold (19) is defined as its dimension that is vertical to the perimeter (18) of the central wall (13). In the case of circular lids, the width is measured along the radius of the circle.
  • the width of the fold (19) may be less than the width of the outer wall (12).
  • FIG. 9 shows the use of the lid (10) with cups (20) having lips (22) of different shapes.
  • the cup (20) of Figure 9 has a lip (10) with oval cross-section and that of Figure 10 has a lip (22) with a channel shaped cross-section, that received the tip of the fold (19), in Figure 10 the tip of the flap (191).
  • the fold (19) is first pressed by the lip (22) and when the lip (22) of the cup (20) contacts the flap (191), the fold (19) is hinged away from the outer wall (12), trapping the lip (22) between the fold (19), and the central wall (16).
  • the lid (10) is secured on the cup (20), closes effectively the opening of the cup (20) and prohibits undesired spill of the liquid to be consumed.
  • the material used for the production of the lids is a recyclable paperboard.
  • the paperboard may be multi-ply and in some embodiments has three distinct layers of paper.
  • the paperboard does not include any substance, either plastic or other, which would have had rendered the products including said paperboard single-use plastic product according to the EU Directive EU 2019/904 on the reduction of the impact of certain plastic products on the environment that came into force on 3 July 2021 and the related Commission guidelines on single-use plastic products: 2021/C 216/01.
  • the plies of the paperboard include cellulose fibers, for example fibers having a length of a few mm, such as 1 mm to 2 mm, and may also include other substances such as minerals, lignine, binding agent or any other substances, which do not render the lid single-use plastic product.
  • FIG. 8 shows the exploded view of the wall of a circular lid, where the creases can be seen scattered over the entire surface of the outer wall (12) and the fold (19). In some examples the creases (15) on the fold (19) and more dense than the creases (15) on the outer wall (12).
  • Figure 2 shows lids (10) stacked one on top of each other.
  • the formation of the skirt (16) with the fold (19) facilitates stacking, as the lid (10) that fits inside another, pushes the fold (19) of the other lid to the outer wall (12).
  • Figure 6 shows a lid (10) with the fold (19) forming an angle with respect to the outer wall (12).
  • the Figure shows the lid (10) applied to the cup (20), with the lip (22) of the cup (20) trapped between the outer wall (12) and the fold (19) of the skirt (16).
  • Figure 7 shows a lid (10) with the fold (19) with a flap (191) that is in contact with the lip (22). As it can be easily seen, the lids are not permanently attached to the cups.
  • the single-use paper lid may have different shapes and diametres.
  • a non-limiting example of a circular lid with internal diameter of 90 mm is shown in Figure 11 .
  • the dimensions and tolerances in Figure 11 are given only as an example, since the single-use paper lid may have different shapes and internal diameters, including but not limited to 90 mm & 95 mm.
  • the features of the paper lids are such that may close under an oval-, flat- or snap-rim of paper or plastic cups on one hand and deliver secure closure at the cup rim, preventing spill-over of the cup content, on the other.
