Definitions

  • the present invention relates to a container according to the preamble part of claim 1.
  • the general problem of the hot beverage cups in PE cardboard is that of the outside temperature of the cup, excessive with respect to human bearableness limits (empirically assessed to be around 60°C).
  • the hot beverage (coffee, tea, cocoa, etc.) is commonly served at a temperature ranging from 80°C to 95°C.
  • the outside temperature of the cup readily (in 30 seconds, max. 1 minute) reaches >80°C values (when the beverage is served at 95°C). At +10 minutes the outside temperature is still >75°C.
  • An empirical method for partially overcoming the problem is that of serving the beverage in two stacked cups.
  • the outside one is dispensed for free and constitutes a support of the inside one, which contains the beverage.
  • versions do exist wherein the creased portion lies on the inside (less contact with the cup) or on the outside (lessor contact with the fingers).
  • the outside temperature remains at >65°C for at least the first 6 minutes. Further the appearance (mouldability, appeal) of the container is anyhow comprised.
  • the sole invention truly meeting the requirement of maintain a ⁇ 60°C temperature is polystyrene foam, which however is of quite scanty mouldability and unpleasant to contact with the user's lip.
  • a type of cup provided with a wall having three layers, the intermediate thereof being creased, is known form US-A-5,542,599.
  • the thermal insulation value thereof is still ineffective (>70°C temperature), and the cup is complicated and costly to manufacture.
  • a container according to the preamble part of claim 1 is known from DE-A-198 40 841.
  • the upper end region of the outside skirt is connected to the advantageously rigid container top edge region by gluing or sealing with the free outside skirt edge clamped between the container top edge section and the knurled upper container bead. Due to the formation of the groove with the inwardly protruding step below the top edge section of the container wall an insulating spacing is provided between the outside skirt and the container wall.
  • the outside skirt extends over the entire length of the container wall.
  • the lower rim of the outside skirt is rolled around a bottom flange of the container.
  • an outwardly bent part of the bottom of the container or an outwardly bent part of the container wall is situated as an additional spacer.
  • the inwardly rolled outer skirt rim is attached to the container bottom structure.
  • the outside skirt can be prefabricated only partially, because the rolling procedure of the lower outside skirt rim and the attachment of the outside skirt rim on the bottom structure needs additional manufacturing steps.
  • the outside skirt fully covering the container hides the double wall concept of the container.
  • the direct connection between the lower outside skirt rim and the bottom structure of the inner container creates an undesirable heat bridge such that the lower region of the outside skirt heats up relatively rapidly when hot liquid fills the container.
  • a major advantage of having the groove forming the inwardly protruding step in the upper container edge section is increased rigidity in the upper container edge section and a well defined insulating spacing between the inner container wall and the outside skirt in the lower part of the container.
  • the insulating container of EP-A-10 31 514 is fabricated by combining an inner prefabricated paper container and a prefabricated outside skirt.
  • the upper sharp or inwardly rolled rim of the outside skirt is set below the curled bead of the inner container.
  • the skirt extends over the full height of the container.
  • a lower, inwardly rolled rim of the outside skirt rests on the container wall in the bottom region of the container.
  • Outwardly creased, circumferential grooves in the container wall contact the outside skirt.
  • the outside skirt is attached e.g. by gluing or sealing in at least on the of the circumferential contact zones to the container.
  • the contact zones create undesirable heat bridges and insulation separation webs in the middle region of the height of the container such that the outside skirt tends to locally heat up relatively rapidly when the container is filled with hot liquid.
  • the object of the present invention is to eliminate the above-mentioned drawbacks of the beverage containers and cups of the state of the art by providing a "laminated container", having an outside skirt, side heat-sealed like in cups, but bottomless with an inwardly bent rim in the bottom section thereof.
  • a particular object of the present invention is to provide a container of a double wall type which is easy to manufacture for fair costs, has an attractive appearance and assures improved insulation.
  • the inner container and the outside skirt both can be completely prefabricated. It is only necessary to put the outside skirt on to the inner container and to attach the outside skirt at the upper container edge section. The container then is ready for use. Since the outside skirt is shorter than the entire height of the inner container such that the lower outside skirt rim rests on the inner container wall at a higher elevation than the height of the bottom, the appearance of the container is attractive and directly indicates the double wall structure. Furthermore, the short outside skirt allows to save material. An important aspect is that the lower outside skirt rim only resting on the inner container wall does not create a direct heat bridge such that the lower part of the outside skirt does not heat up rapidly. Of importance is further that the position of the outside skirt lower rim higher than the bottom of the container allows to achieve a short stacking height of several of such containers.
  • the present invention provides a container for beverages or the like comprising a body having a wall, characterised in that it further comprises an outside skirt apt to near-totally coat said wall, the former being fixedly arranged onto said body and externally to the latter and kept spaced therefrom with a groove obtained at the top area of the container and with a bottom edge obtained on said skirt apt to rest onto the wall.
  • the container being further characterised in that it has an annular groove obtained onto the wall and projecting internally to the container, the groove being apt to provide a support for a respective bottom edge of a skirt of a related container, rising thereabove when in a stacked condition.
  • cup 1 having an outside skirt 2 whose spacing from the inside wall 3 of the cup gradually increases bottomwise is shown.
  • the spacing between the cup 3 and the outside skirt 2 is maintained substantially and almost constant, by means of forming a "step shaped" groove onto the inside cup.
  • the outside skirt 2 contacts the cup wall 3 at a markedly narrowed area, the area being not lapped by the stationary liquid (the filling mark being provided at a lower height).
  • Below the groove 4 the skirt 2 never comes into contact with the inside wall cup, provided a material of suitable rigidity is selected, therefore air that gap is preserved.
  • the air gap thus formed creates an effective thermal insulation for the hot or cool product contained therein.
  • the container of the present invention when a hot beverage is contained therein the outside temperature of the skirt is always maintained at ⁇ 60°C. Moreover, by virtue of the particular embodiment, the product is easily mouldable and easily decorated, as well as of pleasant appearance, both to the touch and visually.
  • a second embodiment of the container of the present invention wherein the outside skirt 2 is maintained spaced from the inside wall 3 at the top section of the container by obtaining a perimetral groove 7 during the cup mould-forming stage.
  • This solution allows to maintain the skirt 2 spaced from the wall 3, differing from the abovedisclosed embodiment in that the outside skirt 2 is not parallelly arranged onto the wall 3 of the container, rather having a divergence starting from above the wall 3 and gradually straying therefrom by means of the groove 7 and of the bottom edge 5.
  • the outside skirt 2 have the end flange 5 not at the same height of the bottom.
  • the former is shorter than the whole height of the container wall, in order to make apparent the skirt-inside cup slack, thereby better setting off the product.
  • the rounded edge 5 of the skirt 2 may be 'flattened' during the forming thereof with an additional step in the manufacturing process of the container.
  • the container may have a edge 5 flattened onto the skirt 2.
  • This solution anyhow allows to preserve an air gap of about 1.2 mm, to ensure a level of thermal insulation, and a stacking height improved of about 6-8 mm with respect to the double wall containers of the state of the art.
  • perimetral grooves 8 in the longitudinal direction and at the bottom section of the skirt 2 may be obtained, so as to avoid a "suction effect" making it difficult to detach one container from another.
  • annular groove 6 be obtained onto the inside wall 3 of the container during the initial mould-forming step of the container.
  • the groove 6 is apt to provide a support for the edge 5 of a skirt of a cup when in the stacked condition.
  • a plane blank apt to make said container 1 once assembled is provided.
  • the blank has an outside surface 2 and an inside surface 3. Then, it is provided that onto the surface 3 the creasing 6, apt to project internally to the container once assembled, be obtained.
  • a second process for implementing the container 1 of the present invention wherein the pre-process blank be plain, may be provided. Then, the latter is arranged on a revolving supporting member of a mould-forming apparatus.
  • the revolving supporting member has on the surface thereof a perimetral groove apt to obtain a respective creasing 6 onto the surface 3 of the container 1 when the supporting member engages to a complementary outside knurl.
