Definitions

  • the invention relates to a heat-insulating base made of a thermally insulating material for vessels, in particular for plates, bowls, glasses and cooking vessels containing food or drinks.
  • the present invention has for its object to provide a pedestal of the type mentioned, which this after avoid parts and which allows prepared heated or chilled food and beverages to be kept at a slightly changing temperature before and during consumption.
  • the invention is based here on the knowledge that the heat transfer between the vessel containing the food or beverage and the vessel base, in particular a table top, is essential for cooling a hot dish or a hot beverage or for heating a cooled dish or a chilled beverage contributes and that even small temperature changes of a few degrees can impair enjoyment.
  • the base has the features stated in the characterizing part of patent claim 1.
  • the cavity enclosed by the two parts not only provides optimal heat insulation, but also makes it possible to keep the material thickness of the base low, so that the heat transfer between the vessel and the base or between the base and base becomes very low.
  • the cavity can contain air.
  • the cavity can also contain an inert gas or be evacuated. It is advantageous to produce the upper part, which has a parting surface, from a temperature-resistant plastic, while the lower part, which is intended to be placed on a base, is made from a thermally highly insulating plastic.
  • Fig. 1 is a plan view of a plate or
  • 3 is a plan view of a stand for bowls, cooking vessels and the like.
  • Fig. 4 shows a section along the line IV-IV in
  • Fig. 3, 5 shows a section of the edge zone from FIG. 3 on a larger scale.
  • the heat-insulating pedestal shown in FIGS. 1 and 2 is intended in particular for plates, plates or glasses.
  • the pedestal is composed of two approximately square shells 1 and 2, which are connected to one another along their edges 3 and firmly and tightly connected at this point, so that the shells 1, 2 enclose a cavity 4.
  • the upper surface 5 serves as a serving or support surface for a plate, a plate or a glass and is designed as a depression with a boundary edge 6.
  • the lower surface 7 is intended to be placed on a support, for example a table, and for this purpose has an annular support projection 8.
  • the outer diameter of the ring projection 8 is slightly smaller than the inner diameter of the boundary edge 6, so that pedestals according to FIGS. 1 and 2 can be stacked in any number.
  • the outer shape of the base can also be circular instead of square and can also have any dimensions that are adapted to the respective vessel.
  • the two shells 1 and 2 consist of a highly insulating, dishwasher-safe plastic, for example polystyrene, ABS or SAN.
  • the upper parting surface can be printed, for example by means of the known tampon printing process.
  • these edges can be welded together, preferably by means of ultrasound.
  • the two shells 1, 2 can also be screwed together, a sealing ring being inserted along the edges 3 for sealing.
  • the cavity 4 enclosed by the shells 1 and 2 can contain air in the simplest case.
  • a slight improvement in thermal insulation, expressed in degrees of temperature, but important for the optimal enjoyment of warm or cold dishes, can be achieved by either filling or evacuating cavity 4 with an inert gas, for example argon. This further reduces the heat transfer between the vessel placed on the base and the base on which the base is placed.
  • the heat-insulating base shown in FIGS. 3 to 5 is intended in particular for setting down plates, bowls or cooking vessels such as roasting pans and in turn has two bowls 11 and 12 which are firmly and tightly connected to one another along their edges 13.
  • the base or the shells 11 and 12 have an essentially square shape.
  • the general shape can of course also be rectangular, which is advantageous for elongated plates and bowls.
  • the two shells 11 and 12 in turn enclose a sealed cavity 14 which either contains air or is filled with an inert gas, for example argon, or is evacuated.
  • the upper surface 15, ie the outer surface of the bowl 11, serves as a storage or support surface for the plates, bowls or cooking vessels.
  • the lower surface 16, ie the outer surface of the shell 12, is intended to be placed on a support, for example a table, and is provided with support ribs 17 for this purpose.
  • the lower shell 12 consists of a highly insulating, dishwasher-safe plastic, for example made of ABS plastic, to which so-called "bubbles", ie small, essentially round particles, can also be added to reduce the thermal conductivity.
  • the upper shell 11 also consists of a thermally insulating plastic which, however, has a higher temperature resistance of, for example, 140 ° C. than that of the lower shell 12.
  • This plastic can be, for example, polycarbonate, reinforced polypropylene or reinforced polyamide.
  • this base can also be used to place very hot cooking vessels, such as roasters.
  • the upper shell 11 essentially has the function of forming a temperature-resistant parting surface, while the lower shell 12 creates the desired thermal insulation by forming most of the cavity 14.
  • the height of the upper shell 11 is significantly smaller than that of the lower shell 12.
  • a plate-shaped part can also be provided, which is tightly connected to the lower shell 12.
  • the plate-shaped part which should be temperature-resistant (120 to 140 ° C.) can in turn consist of a temperature-resistant plastic, or else of glass, for example a hard glass or a borosilicate glass.
  • the two shells 11 and 12 according to FIG. 4 are firmly connected to one another by screws 18, the shells 12 and 11 being molded on with corresponding screws in order to support and receive the screws 18 Projections 19 and 20 are provided.
  • a sealing ring 21 is inserted along the edges 13 of the two shells.
  • the edges 13 of the two shells 11, 12 can also be welded to one another, in particular by using ultrasound.
  • a handle is molded onto the upper shell 11. This does not hinder the storage of several pedestals in a vertical position. Rather, a pedestal can be removed from the vertical stack with handles 22 pointing upwards or forwards with ease and placed comfortably on a table or moved on the table without touching the possibly hot storage surface 15 or the hot vessel located on the serving surface 15.

Abstract

Le dessous de plat pour un récipient d'aliments ou de boissons se compose de deux enveloppes (11, 12) reposant l'une sur l'autre le long de leurs bords (13) et reliées entre elles de manière étanche au moyen d'un vissage (18) et d'une bague d'étanchéité insérée (21). La cavité creuse (14) entourée des enveloppes (11, 12) contient de l'air ou un gaz noble, par exemple de l'argon, ou est sous vide. L'enveloppe supérieure (11) comportant une surface de pose (15) pour le récipient est à base de plastique résistant aux températures. L'enveloppe inférieure (12) à poser sur une table, plus haute que l'enveloppe supérieure (11), est à base de plastique à forte isolation thermique. Une poignée plate (22) est formée sur l'enveloppe supérieure (11). Le dessous de plat empêche en principe tout transfert de chaleur du récipient à la table, il est léger, facile à manipuler et peut être lavé en machine.
