Definitions

  • the invention relates to a warming can according to the preamble of patent claim 1, that is to say a pouring container which is particularly suitable for storing hot drinks and consists of an inner container which holds the hot liquid and a heat-insulating jacket surrounding it.
  • warming cans are known, in which the inner container itself is designed to be heat-insulating in the form of a double-walled so-called Dewar vessel and is surrounded by a shock-proof jacket for its mechanical protection (see, for example, DE-GM 81 12 201 and DE-AS 26 58 295).
  • warming cans are known which consist of a glass inner container, an insulating layer surrounding it - for example made of plastic foam - and an outer jacket which is made of metal, for example (see e.g. DE-PS 30 45 896).
  • DE-OS 29 52 557 shows a coffee pot which consists of a glass inner container and a surrounding, two-part, non-insulating protective jacket.
  • this object is achieved in a warming can of the type mentioned at the outset, which has a glass inner container, an insulating layer and an outer shell made of elastic plastic material surrounding it, in that the upper part of the outer shell has a circumferential collar which overlaps the edge of the glass inner container, the inner edge of which has no any additional sealant rests around the inside of the glass container rim under elastic prestress. It has been shown that the elastic prestressing of the inside edge of the collar produced by elastic deformation of the said collar edge ensures the required sealing. Due to the elastic deformability of the collar and its inner edge, dimensional deviations of the glass container of a few millimeters are easily absorbed both in the radial and in the axial direction. According to the invention, the security of the seal can be increased further in that the inner edge of the collar has a labyrinth of seals made of circumferential sealing lips.
  • the glass container has a radially widening upper edge region, on which the inner edge of the collar of the plastic outer shell is sealingly supported under radial and / or axial elastic prestress.
  • the outer shell upper part is preferably designed in such a way that its lower edge overlaps the upper edge of the base part, the base part having a circumferential radial projection which, under radial pressure, lies around the inner surface of the upper part in a sealing manner under radial pressure.
  • the radial press fit achieved in this way achieves a permanent, secure seal between the two outer shell parts, an approximately triangular cross-sectional shape with the tip pointing outwards having proven particularly useful for the circumferential radial projection.
  • the upper and lower parts of the outer shell are preferably provided with interlocking fixing means, which are arranged on the inner wall of the upper part and the outer wall of the bottom part, in the region which, after they have been assembled, lies above the sealing radial projection.
  • These fixing means are preferably designed as corresponding undercuts which engage under pre-tension acting parallel to the central axis of the can and which, in various advantageous embodiments, have the shape of an internal and external thread or have radial pin and these corresponding recesses or a Bejonett locking.
  • the bottom part of the outer shell is a ring which exposes the entire middle part of the glass container bottom with an upward-looking, circumferential sealing lip and which is sealed all around at the edge area of the jug under parallel to the central axis of the jug Glass container bottom supporting inner edge.
  • the middle part of the glass container base which is left free in this way can thus be brought into direct thermal contact with the warming plate of the coffee machine.
  • the proposed design of the inner edge of the base ring also ensures a secure seal to the inner glass container, this construction also contributing to compensating for height tolerances of the inner glass container.
  • radial ribs can be formed in the angle between the side wall of the base part and the collar extending to the inner edge, which bring about a specific stiffening of the collar, which enables flexible adaptation to special features of the overall construction.
  • the intermediate space surrounding the glass inner container and sealed on all sides by the outer shell according to the invention is already an effective thermal insulation layer, in preferred embodiments of the invention it is filled or preferably filled with insulating materials known per se, such as - in particular spherical - foamed plastic particles completely foamed with fine-pored plastic foam.
  • the bottom part 3 inserted into the outer shell upper part 2 from below has a circumferential radial projection 3.1 with an approximately triangular cross section, which is supported in a form-fitting, sealing manner on the inside of the reinforced upper part edge 2.5 under radial pressure.
  • the ring-shaped outer shell bottom part 3, which leaves the container bottom 1.2 free, is supported with its inner edge 3.3 designed as a sealing lip in a form-fitting, all-round manner on the edge region of the container bottom 1.2.
  • stiffening ribs 3.4 can be provided, by means of which the hardness of this support can be influenced.
  • the radial projection 3.1 which effects the radial seal between the upper part 2 and the bottom part 3 of the outer shell - that is to say within the sealed intermediate space - is on the inner wall of the upper part 2 has an internal thread 2.2 and an outer thread 3.2 on the bottom part 3.
  • the two outer shell parts are fixed to one another by means of these threads, the collar 2.1 and the inner edge 3.3 of the base part 3, which is designed as a sealing lip, being given the pretension by elastic deformation, which causes their positive pressure.
