Wafer half-shell, a method for its preparation, and a food product including it
View Patent ↗A wafer half-shell is described which has a mouth delimited by at least one annular surface and one or more side walls, in which the mouth surface and the surfaces of the side wall have a substantially smooth surface finish. Preferably the outer surface of the side wall has a porous, continuous or discontinuous region which extends peripherally and is receded relative to the mouth surface of the half-shell, resulting from the cutting of a radial wall connected to the side wall of the half-shell in a receded position relative to the annular surface defining the mouth of the half-shell. The annular coupling surfaces of the complementary half-shells have preferably centering means which are complementary each other. The half-shell is useful particularly for the production of a food product comprising a pair of half-shells fitted together mouth to mouth and including a mass of liquid filling.
1. A food product, comprising a pair of half-shells, fitted together mouth to mouth and including a mass of filling, wherein at least one of the half-shells is a wafer half-shell having a mouth delimited by at least one annular surface and one or more side walls, in which the mouth annular surface and the surfaces of the side wall have a substantially smooth surface finish, wherein the outer surface of the side wall has a rough, continuous or discontinuous region which extends peripherally and is receded relative to the mouth annular surface of the half-shell.
2. A food product according to claim 1 , further comprising a mass of filling contained in the pair of half-shells.
3. A food product according to claim 1 , wherein the rough region is the surface resulting from the cutting of one or more radial walls connected to the side wall of the half-shell in a receded position relative to the annular surface defining the mouth of the half-shell.
4. A food product comprising at least two wafer half-shells coupled one to the other along annular mating surfaces defining their mouth profile, wherein said annular mating surfaces of each of said half-shells have centering means complementary one to the other and wherein at least one of said half-shells has an outer side wall with a rough, continuous or discontinuous region extending peripherally, which is receded relative to the mating annular surface of said half-shell.
5. A food product according to claim 4 , wherein said centering means comprise formations susceptible of mutual engagement.
6. A food product according to claim 4 , wherein said centering means comprise annular mating surfaces having a toothed profile, a U-shaped profile, a V-shaped profile, a L-shaped profile, a Greek-key pattern profile or a zigzag profile.
7. A food product according to claim 4 , wherein said centering means comprise tapered annular mating surfaces.
8. A food product according to claim 4 , wherein said annular mating surfaces and the surface of said centering means have a smooth surface finish.
9. A food product according to claim 4 , wherein the rough region is the surface resulting from the cutting of one or more radial walls connected to the side wall of the half-shell in a receded position relative to the annular surface defining the mouth of the half-shell.
