Patent

CA 2515234

The invention relates to a method for producing cookware (1) consisting of a base body (5) that is attached to a base (2), in particular a pot, pan or similar. In a first step of said method, the base body (5) is produced in one- piece, preferably in a deep-drawing process and in a second step, the base body (5) is connected to the preferably multi-part base (2), which is composed of an inlay (6) and a shell (7) that encapsulates said inlay (6). The aim of the invention is to provide a simple and cost-effective method for producing cookware (1) comprising a base (2) that only deforms within narrow tolerance limits, even when subjected to comparatively high thermal stress. To achieve this, the base (2) is calibrated by means of a displacement-controlled press, preferably a toggle press.

L'invention concerne un procédé servant à produire un ustensile de cuisine (1), notamment une casserole, une poêle ou un autre élément similaire, formé d'un corps de base (5) sur lequel est placé un fond (2). Dans une première étape de ce procédé, le corps de base (5) est réalisé en une seule pièce de préférence par emboutissage profond et, dans une deuxième étape, le corps de base (5) est relié au fond (2), de préférence composé, présentant une garniture (6) ainsi qu'une capsule (7) recevant la garniture (6). L'invention vise à proposer un procédé à mise en oeuvre simple et économique, qui permette la production d'un ustensile de cuisine (1) présentant un fond (2) ne se déformant que dans d'étroites limites de tolérance même en cas de sollicitation thermique comparativement élevée. A cet effet, le fond (2) est calibré au moyen d'un dispositif de compression commandé par déplacement, de préférence au moyen d'une presse à genouillère.
