Method for manufacturing a flexible mold with peripheral stiffner, and mold resulting from same method

A food mold comprising:

• a food mold body made of a mold body material and having a plurality of cells with flexible walls, each of the plurality of cells being having a bottom and being open on a common access face, the common access face itself having a peripheral rim extending radially outward from the plurality of cells, the peripheral rim having a top main face and a peripheral stiffening element in the form of a continuous annular reinforcement, at least one intermediate stiffening element, the at least one intermediate stiffening element entirely embedded in the mold body material and joining opposing zones of the peripheral stiffening element the peripheral stiffening element having a cross-section with a first width and a second width, wherein the first width is equal to the second width and the first width and the second width are orthogonal to each other, and at least one intermediate stiffening element, wherein:
• the peripheral stiffening element is entirely embedded in the mold body material,
• around the peripheral stiffening element, the mold body material has no through passages free or blocked between the peripheral stiffening element and an outer surface of the mold body material, and
• the peripheral stiffening element edges a strip of the mold body material forming the food mold body in at least two opposing gripping zones of the peripheral rim, said strip producing an increase in width of the at least two gripping zones and exhibiting a greater flexibility than that of the peripheral stiffening element.

A food mold comprising:

• an elongated food mold body having two opposite long sides and two opposite short sides, the food mold body made of a mold body material and having a plurality of cells with flexible walls, the plurality of cells being open on a common access face, the common access face having a peripheral rim extending radially outward from the plurality of cells, the peripheral rim having a peripheral stiffening element in the form of a continuous annular reinforcement and a flexible strip between the peripheral stiffening element and the plurality of cells, and at least one intermediate stiffening element wherein:
• the width of the flexible strip on the two opposite short sides is greater than the width of the flexible strip on the two opposite long sides,
• the peripheral stiffening element is entirely embedded in the mold body material,
• around the peripheral stiffening element, the mold body material has no through passages free or blocked between the peripheral stiffening element and the outer surface of the mold body material, and
• the at least one intermediate stiffening element is entirely embedded in the mold body material and joining opposing zones of the peripheral stiffening element.
