Abstract

The plate has an inner cavity (1) which is filled with a substance which can accumulate and retain more heat than the material from which the plate itself is made. The heat accumulating/retaining material can be a stearin, paraffin wax, or a natural or synthetic wax with melting and solidification temperatures between 40 and 80 deg.C. The cavity has inner studs (2) to conduct heat from the accumulating material to the surface of the plate in contact with the food, and to increase the plate's mechanical rigidity. ADVANTAGE - Keeps food warmer for longer.

Description

ASSIETTES,PLATS,USTENSILES DIVERS A
REFROIDISSEMENT RALENTI
La présente invention concerne un dispositif de stockage et déchange d'énergie calorifique destiné à maintenir à une température optimale et le plus longtemps possible,des assiettes ou autres ustensiles préalablement préchauffés à une température supérieure à cette température optimale.PLATES, DISHES, VARIOUS UTENSILS
COOLING IDLING
The present invention relates to a storage device and heat energy exchange for maintaining at an optimal temperature and as long as possible, dishes or other utensils previously preheated to a temperature above this optimum temperature.

Traditionnellementoles assiettes et plats servant au cours d'un repas sont préchauffés pour garder les aliments au chaud durant le temps du repas. Traditionally, plates and dishes used during a meal are preheated to keep food warm during the meal.

L'invention a pour but de prolonger au minimum de 100% le temps pendant lequel les aliments restent à une température agréable(T > à 5Q C).Elle consiste à prévoir une cavité (1) de volume VO à la base de assiette (3) et de la garnir d'un corps de volume V1 (V1 < VO) ayant la propriété d'accumuler de façon réversible de la chaleur dans une plage de 40 à 80 C. De façon non limitative, nous citerons comme corps ayant ces propriétés: les paraffines, les cires synthétiques ou naturelles,les stéarines etc. The aim of the invention is to prolong by at least 100% the time during which the food remains at a pleasant temperature (T> to 5 ° C.). It consists in providing a cavity (1) of volume VO at the base of the plate ( 3) and to fill it with a body of volume V1 (V1 <VO) having the property of reversibly accumulating heat in a range of 40 to 80 C. In a nonlimiting way, we will quote as a body having these properties: paraffins, synthetic or natural waxes, stearines etc.

La cavité (i) pourra être équipée de plots (2) destinés à améliorer la résistance mécanique et le transfert de chaleur entre le corps accumulateur et la face de l'ustensile en contact avec les aliments.L'orifice (4) utilisé lors du remplissage de la cavité (1) par le corps accumulateur est obturé après remplissage. The cavity (i) may be equipped with studs (2) intended to improve the mechanical strength and the heat transfer between the accumulator body and the face of the utensil in contact with the foods.The orifice (4) used during the filling of the cavity (1) by the accumulator body is closed after filling.

La figure 1 représente en coupe une assiette modifiée selon l'invention. Figure 1 shows in section a trim modified according to the invention.

La figure 2 represente 1 évolution de la température de surface (Ts) d'une assiette en contact avec l'aliment; -la courbe C1 représente l'évolution de la Ts d'une assiette conventionnelle de masse (M) -la courbe C2 représente lévolutîon de la Ts d'une assiette de même masse (M) modifié selon l-invention.  Figure 2 shows the evolution of the surface temperature (Ts) of a plate in contact with the food; the curve C1 represents the evolution of the Ts of a conventional mass attitude (M). The curve C2 represents the evolution of the Ts of a plate of the same mass (M) modified according to the invention.
