FR2718156A1 - Vessel to keep food hot - Google Patents

Abstract

The vessel to hold hot beverages and food is in two parts of porous terracotta. The inner hollow part has an inner fired cladding which is in contact with the contents, and the outer part has a similar coating over the whole outer surface. A firing at 1110 deg.C. vitrifies the coating and welds the parts together, leaving a porous base.

Description

DESCR-IPTOi 1 JASLE] - U - '' mE3. PRE_ S_0 .. FiDES 2a present invention

  relates to dishes to keep food hot without risk of burns

  accidental due to its grip or handling.

  _. we already know the dishes and the different ways in which we heat them so that they keep hot the food they contain once served at the table for the meal ... alré the effectiveness of this tecaique, the

  Using these very hot dishes remains delicate.

  requires certain precautions and sometimes provokes

  accidental burns or carelessness.

  The purpose of this process is to eliminate all of these drawbacks

  a-in to offer a classic handling of these dishes.

  _lle consists of a part of porous terra cotta forming container, covered with staruiferous enamel only on its concave surface yes is in ccntact with food and: oreuse on its interior surface revosant on the table; "sle auzre part de même: -natire, the circumference, -maillée it entirely and forming a 4pice perfectly i: remaable. ures assembly of the two parts, an annealing at 1.100 degrees Celsius will fuse the enamel, weld and vitrify the covered to obtain a piece of crockery of classic appearance that it is possible now to plonze it two to three minutes in water so that it-soaks this liauide uniauly in its part offered to the ocrosi-ty, the circumference pre-sensitive remaining perfectly dry in itself. a short passage of this tableware in an oven of the "microwave" type will cause a re; heating to 1CC after elsus of the liquid and Dar result from the art-ie which - contains only this, without risk of bursting because the unvailed surface premet the stiff exhaust of any vapors which may form there. The prehensile edge, perfectly dry, remains sheltered from this process and preserves the room temperature co However, at this temperature scale, heat transfer in a dry ceramic medium is insignificant. 2 According to particular embodiments, the different parts making up this tableware are obtained by conventional stamping or molding of ceramic clay, they are subjected to a first firing at a temperature close to 900 degrees Celsius then covered with so-called food-grade stanniferous enamel. on some of their surfaces, assembled by contact and annealed at 1,100 degrees Celsius. This last firing unites them with enamel welding and seals the desired parts by vitrification. The average thickness of this tableware is between 4 and 6 millimeters to ensure good capillarity in its part which soaks the water and correct solidity. The shapes may vary.

  those of any classic tableware.

  The other comoosants of discositiú azpara will

  annexed drawings yes illustrate one embodiment

by way of nonlimiting example.

  The accompanying drawings illustrate the invention: -The drawing 1/3 shows in sections the part which can be opened or surrounded (fi,. 1) and the hollow part or container (fig. 2) before assembly and cooking. Traits

Claims (4)

CLAIMS 4   1) Device for obtaining a crockery capable of containing and keeping drinks or hot food and eliminating any danger of accidental burning due to its grip or handling characterized in that it consists of two parts of porous terracotta, the bottom hollow part (fig. 2) is covered with stanniferous enamel only on its surface which is in contact with food, the upper part (fig. 1) which can be grasped, is covered with this same enamel over its entire surface. An annealing at 1,100 degrees Celsius vitrifies the enamel and welds the two parts to obtain dishes with an external base remains porous (fig. 3).   2) Device according to claim 1 characterized in that if the dishes are immersed in water, only   its lower part (fig. 2) will soak this liquid.   3) Device according to claims 1 and 2   characterized in that the water soaked in its porous part will be brought to 100 degrees Celsius by a short passage in the oven of the "microwave" type and therefore becomes able to conserve   hot food or liquids contained therein.   4) Device according to claims 2 and 3   characterized in that the upper part (fig. 1) which is not soaked does not undergo the same process and remains at ambient temperature thus allowing it to be grasped without danger of burns.
