Definitions

  • the invention relates to a double-wall container with an inner cup-shaped container body having a peripheral wall defining a top edge section of the double-wall container, a bottom, and an outer skirt surrounding at least partly the peripheral wall of the container body and extending from the top edge section towards the lower end of the double-wall container at a dis ⁇ tance to the peripheral wall of the container body such as to leave a space therebetween.
  • Double solid wall containers for hot beverages such as paper or cardboard cups often face the problem that the outside sur ⁇ face of the cup is getting very hot when a hot fluid or bever ⁇ age such as hot coffee or tea is served. This is due to the fact that the gripping surface of the cup is not adequately shielded against the heat. Moreover, the insulation is insuf ⁇ ficient and the beverage's temperature declines rapidly.
  • double-wall containers are reg ⁇ ularly used for serving hot beverages.
  • These kinds of contain ⁇ ers are basically formed by an inner cup member that accommo ⁇ dates the tempered beverage and an outer cup member in the form of a sleeve or skirt that surrounds the peripheral wall of the inner cup.
  • the air gap has an insulating function to keep a hot beverage tempered and to prevent the outer gripping surface from getting hot to allow the customer to hold the cup for a longer time.
  • Standard designs of double wall containers have limited success in in ⁇ sulating the customer's hand from the heat as often a suffi ⁇ cient air gap is not provided consistently from the top to the bottom of the sleeve, especially where the hand would normally hold a cup. Due to the continuous contact points, of some ex ⁇ isting double wall hot cup designs, between inner and outer container walls where the cup is held, the heat transfer to the customer's hand is increased.
  • EP 0 934 202 Bl discloses an insulating cardboard double-wall container with a paper cup body that has a number of horizontal ribs provided on its peripheral wall surface.
  • the paper cup body is surrounded by a sleeve.
  • the horizontal ribs which are formed on the side wall of the cup body so as to project outwardly, have the functions of improving the strength of the cup body and forming a space for heat-insulation between the outer peripheral wall of the inner paper cup and the inner wall of the sleeve, providing a smooth outer wall for printing of designs.
  • the upper end portion of the sleeve is joined by means of an adhesive agent with the outer periphery of the side wall of the cup body.
  • the horizontal ribs support the side wall of the sleeve, thus making it possible to prevent the side wall of the sleeve from being warped inward but pre ⁇ vent an efficient convection of the heat in upward direction. Heat could be trapped within the gap and in particular the supporting sections near the ribs, unnecessarily raising the temperature of the surrounding paperboard wrap material which is uncomfortable for the customer.
  • the peripheral wall of the container body is provided with a plurality of embossed pro ⁇ trusions protruding outwardly from the peripheral wall such as to provide a support for the outer skirt and to form air chan ⁇ nels between adjacent protrusions.
  • the protrusions are spaced, in particular equally spaced with adjacent protru ⁇ sions being equally spaced from each other.
  • the protrusions are arranged so as to separate the space between the outer skirt and the container body into an upper and a lower air gap section, wherein the upper air gap section and the lower air gap section are in fluid communication through the channels. In other words, through the air channels, an air exchange is possible between the upper and the lower air gap.
  • the channeling emboss on the inner container body is based on the idea of corrugate clutches that help to channel the heat away from the outer skirt wall where the customer regularly holds the cup. This provides for a better insulating effect than standard double-wall containers. As air provides a good insulating barrier between the inner and outer wall, and as the heat in the space in the double wall rises, the heat natu ⁇ rally rises in upward direction.
  • the channels facilitate the convection of air in vertical direction and help to lead the heated air inside the space away from the protrusion section of the container body and into the upper air gap.
  • the protru ⁇ sions provide the relevant contact points between the peripheral wall of the inner container and the outer wall.
  • the heat transfer between the peripheral wall and the outer wall is significantly less than in regular cups on the market.
  • the gaps between the contact points lead to overall lower heat transfer per cm 2 when held in the hand at this point.
  • the protrusions may be arranged in the upper section of the container body, in particular in the upper half of the container body. This is the location where the customer regularly holds the paper cup, in particular where he places the thumb and the index finger.
  • the protrusions are provid ⁇ ed at circumferentially spaced locations on the peripheral wall.
  • the plurality of circumferentially-spaced protrusions may be arranged such that adjacent protrusions are equally spaced from each other in circumferential direction.
  • means for ventilating the space between the peripheral wall of the con ⁇ tainer and the outer skirt are provided in the upper air gap section of the double-wall container.
  • the ventilation means is configured to provide a fluid communication between the at ⁇ mosphere and the upper air gap section.
  • the heated air can effectively flow from the lower air gap section through the channels and the upper air gap section to the out ⁇ side.
  • the hot air is not trapped within the air gap which keeps the surrounding paperboard wrap (outer skirt) and in particular the outer gripping section cooler for a longer period of time.
  • the ventilation means can be formed by an air gap between the upper end of the outer skirt and an upper rim of the inner container body, in particular an outwardly curled rim at the top end section of the inner container body.
  • the outer skirt leaves a gap between its upper end and said rim.
  • Said gap can extend around the entire circumference of the double-wall container or at least partly.
  • ventilation holes or gapes can be formed into the outer skirt anywhere in the outer skirt, preferably in the upper end section, to provide means for air exchange between the gap be ⁇ tween the inner cup and outer atmosphere.
  • the upper and lower air gap section may be characterized by straight, respectively smooth portions of the peripheral wall.
  • the protrusions have tear drop shapes.
  • a tear drop shaped protrusion can be characterized as having a round shape at one end and ending in a ta ⁇ pered section at the opposite end.
  • the tear drop shaped protrusions are oriented such as to extend from the tapered end to the round shaped end along the axis of the container body. In oth ⁇ er words, the tear drop shaped protrusions are oriented verti ⁇ cally.
  • the round shaped end of the tear drop shaped protrusion is oriented toward the upper edge of the container and the smaller tapered end is oriented to ⁇ wards the container bottom.
  • the embossing is provided around the axis of the container body in a radial pattern, meaning that the protrusions are distributed around the container axis and that they are horizontally spaced.
  • the protrusions form an outwardly em ⁇ bossed annular region on the outer surface of the container body located between the upper air gap section and the lower air gap section, improve the strength of the container body and also form the space for heat insulation.
  • the channels may respectively be formed between the inner wall of the outer skirt, two adjacent protrusions and the outer pe ⁇ ripheral wall of the container body.
  • the protrusions are applied to the container body by embossing which facilitates manufacturing material efficiency and there- fore reduces material costs and environmental waste.
  • the em ⁇ bossing can be created in-line through the standard manufac ⁇ turing of a high speed cup making facility rather than as a clutch that is transported separately and added to the cup at the point of filling/consumption.
  • the effective support for the outer skirt by the protrusions preserves a smooth outside surface of the outer skirt for printing.
  • the double-wall container is made of a cartonboard, cardboard, paperboard or any other suitable pa ⁇ per-based material.
  • the inner container body may be coated, at least on the inside surface of the container body.
  • the outer skirt may be coated as well.
  • the coating may be a plastic ma ⁇ terial such as a polyethylene (PE) coating or any other type of suitable coating suitable for beverage cups.
  • PE polyethylene
  • the outer skirt is held at the top edge section with a tight fit.
  • the top edge section of the inner container body can formed by an outwardly curled rim, said rim holding the outer skirt in a fight fit.
  • the rim can hold the upper end of the outer skirt with a tight fit between the outer peripheral wall of the inner container body and the rim.
  • the outer skirt is held at the top edge section with a loose fit, meaning that the outer skirt is not fixed to the top edge section.
  • the loose fit be ⁇ tween the outer skirt allows for venting the space between the walls of the container body and the outer skirt.
  • the air inside said space heats up when a hot beverage is filled into the container and expands.
  • the loose fit of the outer skirt at the top section of the container body allows air from the inner space to escape to the atmosphere.
  • the top edge section of the inner container body is formed by an outwardly curled rim, said rim holding the outer skirt in a loose fit.
  • the outwardly curled rim of the inner container body is a curled section of the upper end of the peripheral wall that is bent to the out ⁇ side of the container body such as to form a crimped edge.
  • the lower edge of the rim is spaced from the outer surface of the peripheral wall of the container body such as to form a gap therebetween.
  • the curled rim may form a bearing surface for the outer skirt. The loose fit provides that the outer skirt is disconnected from the inner wall all the way to the top of the container. The only relevant points of contact are the protrusions.
  • the upper end of the outer skirt bears against the rim, in particular against the lower end of the rim or against the rim inside said gap be ⁇ tween the rim and the outer peripheral wall so that the outer skirt is captured by the rim roll, respectively by the curled rim of the inner container body.
  • the upper end of the outer skirt bears against the top edge section with a slight pre-tension, resp. with a light preload. This ensures the correct fit of the outer skirt in the upper section of the double-wall container.
  • the top edge section of the outer skirt may be snapped into the gap between the curled rim and the outer peripheral wall of the container body.
  • the outer skirt wall is fixed to at least some of the protrusions.
  • the outer skirt wall is fixed to the protrusions by gluing or any other type of suitable fixation.
  • the lower end of the skirt is attached to the outer surface of the peripheral wall of the container body.
  • the outer skirt can be affixed to the container body merely at the lower end of the skirt and at the embossing which is spaced apart from the lower end of the outer skirt.
  • the lower end of the skirt is inwardly bent and the bent section is attached to the peripheral wall of the container body.
  • Inwardly in this regard, means that the lower edge of the skirt is folded towards the peripheral wall of the inner container body, so that it forms a curled section de ⁇ fined by substantially parallel leg sections that are connect ⁇ ed by a an intermediate bent section, similar to a loop. Thereby, a consistently broad air gap can be formed.
  • the lower end of the skirt is attached to the con ⁇ tainer body above the lower end of the container body so as to provide a height difference between the lower end of the con ⁇ tainer body and the lower end of the skirt.
  • the protrusions are formed as vertical ribs.
  • Vertical ribs extend along the axis of the container body towards the top edge section, resp. from the lower air gap section to the upper air gap section and are efficient means for directing an air flow between the lower and upper air gap section.
  • a paper cup with an integrated airflow system clearly improves the insulating performance.
  • the upper and lower ends of the ribs may have a round contour to enhance the flowing of the air between the lower and the upper air gap section.
  • the protrusions and in particular the ribs can have a flat surface section for contacting the inner surface of the outer skirt, which provides a rigid support for the outer skirt.
  • the ribs may have a transition to the flat section of the peripheral wall which runs out in a smooth manner into the peripheral wall to enhance fluid flow.
  • the run out has the shape of a smooth curve. This prevents the paper fibers from bursting .
  • the protrusions are dome- shaped in cross-section.
  • the protrusions have a curved surface section for contacting the inner surface of the outer skirt and a periphery which converges in a smooth curve into the peripheral wall.
  • the protrusions Prefera ⁇ bly, the protrusions have a dome-shaped cross section when viewed along the container axis. Additionally or alternative ⁇ ly, the protrusions have a dome-shaped cross section when viewed in circumferential direction. The result is a small contact surface with the outer skirt and the heat transfer to the outer skirt wall is further reduced.
  • the cup-shaped container body has a generally frusto-conical shape with a wider cup opening and a smaller bottom.
  • a generally cy ⁇ lindrical shape is possible.
  • the container body has a bottom with a bottom surface and a folded edge section, wherein the folded edge section is retained in a folded lower end of the peripheral wall.
  • the lower end of the peripheral wall may be inwardly bent, resp. folded radially inwardly so that it forms a curled sec ⁇ tion defined by substantially parallel leg sections that are connected by an intermediate bent section, similar to a loop.
  • the folded edge section of the bottom may engage the curled section between the legs of the loop.
  • This configuration provides a tight fit, in particular in a form-fit manner and is convenient in terms of manufacturing efforts.
  • the fixation of the folded edge can be performed by bonding.
  • the connection can also be an interference fit.
