Method for manufacturing a flexible mold with peripheral stiffener, and mold resulting from said method

A food mold (1),

• comprising a food mold body (2) made of a mold body material, having one or more cells (3) with flexible wall,
• said one or more cells (3) being limited by a bottom (3a) and being open on a common access face (4),
• the common access face (4) itself having a peripheral rim (5) extending radially outward from an inner edge (5d) marking a boundary with the cell or cells (3) and to a free outer edge (5c),
• the peripheral rim (5) having a top main face (5a) and being provided with a peripheral stiffening element (10) in the form of a continuous annular reinforcement (100),
• wherein:
• the peripheral stiffening element (10) is entirely embedded in the mold body material,
• around the peripheral stiffening element (10), the mold body material has no through passages free or blocked between the peripheral stiffening element (10) and an outer surface of the mold body material, and
• the peripheral stiffening element (10) is edged externally, in at least two opposing gripping zones (11, 12) of the peripheral rim (5), by a peripheral strip (11a, 12a) of material forming the food mold body, said peripheral strip (11a, 12a) producing an increase in width of the gripping zones (11, 12) and exhibiting a greater flexibility than that of the peripheral stiffening element (10).
