Abstract
The invention relates to a mold for manufacturing a stick, in particular for cosmetic use. The side wall of said mold has zones of weakness for making the mold easier to deform radially, said zones of weakness being obtained by means of recesses formed in the side wall of the mold and extending longitudinally over substantially the entire height of the mold starting from its bottom end.

A mold for manufacturing a stick of a cosmetic product, wherein the mold has a side wall having an external surface and an internal surface configured to be in contact with the product, the side wall including recesses facilitating radial deformation of the mold, the side wall being deprived of recesses opening out into the internal surface, at least one of said recesses having longitudinal edges having a length on the external surface, the edges comprising portions that are adjacent to a periphery of the mold and spaced apart over at least a part of the length prior to a deformation of the mold, and spaced from an upper end of the recess and from a bottom end of the recess.
A mold for manufacturing a stick of a cosmetic product, wherein the mold has a side wall including recesses facilitating radial deformation of the mold, at least one of said recesses having longitudinal edges having a length on an external surface of the side wall, portions of the edges adjacent to a periphery of the mold being spaced apart over at least a part of the length prior to a deformation of the mold, said portions being located at a position other than an upper end and a bottom end of the recess and wherein the mold has a cavity with a sloping bottom wall.
A mold for manufacturing a stick of a cosmetic product, wherein the mold has a side wall including recesses facilitating radial deformation of the mold, at least one of said recesses having longitudinal edges having a length on an external surface of the side wall, the edges comprising portions that are adjacent to a periphery of the mold and spaced apart over at least a part of the length prior to a deformation of the mold, and spaced from an upper end of the recess and from a bottom end of the recess, and wherein the mold has a cavity having a part formed by two successive conical surfaces converging towards an opening of the mold.
A mold for manufacturing a stick of a cosmetic product, wherein the mold has a side wall including recesses facilitating radial deformation of the mold, at least one of said recesses having longitudinal edges having a length on an external surface of the side wall, the edges comprising portions that are adjacent to a periphery of the mold and spaced apart over at least a part of the length prior to a deformation of the mold, and spaced from an upper end of the recess and from a bottom end of the recess, and wherein the mold has a top portion having a flange.
A mold for manufacturing a stick of a cosmetic product, wherein the mold has a side wall including recesses facilitating radial deformation of the mold, at least one of said recesses having longitudinal edges having a length on an external surface of the side wall, the edges comprising portions that are adjacent to a periphery of the mold and spaced apart over at least a part of the length prior to a deformation of the mold, and spaced from an upper end of the recess and from a bottom end of the recess, and wherein the mold has a flange surrounding an opening of the mold.
A mold for manufacturing a stick of a cosmetic product, wherein the mold has a side wall including recesses facilitating radial deformation of the mold, at least one of said recesses having longitudinal edges having a length on an external surface of the side wall, the edges comprising portions that are adjacent to a periphery of the mold and spaced apart over at least a part of the length prior to a deformation of the mold, and spaced from an upper end of the recess and from a bottom end of the recess, and wherein the mold has an opening defined at least partially by a conical surface, the conical surface having an internal surface configured to be in contact with the product, the side wall being deprived of recesses opening out into said internal surface.
A mold for manufacturing a stick of a cosmetic product, wherein the mold has a side wall including recesses, facilitating radial deformation of the mold, at least one of said recesses having longitudinal edges having a length on an external surface of the side wall, the edges comprising portions that are adjacent to a periphery of the mold and spaced apart over at least a part of the length prior to a deformation of the mold, and spaced from an upper end of the recess and from a bottom end of the recess, at least one of said recesses extending longitudinally beyond a bottom of an inner cavity of said mold.
A mold for manufacturing a stick of a cosmetic product, wherein the mold has a side wall which includes notches facilitating radial deformation thereof, at least one of said notches extending longitudinally beyond a bottom of an inner cavity of said mold, and wherein the depth of the notches decreases on coming towards a bottom end of the mold.
A method for manufacturing a stick of a cosmetic product, comprising:
- pouring said product in a mold having a side wall including recesses facilitating radial deformation of the mold, at least one of said recesses having longitudinal edges having a length on an external surface of the side wall, the edges comprising portions that are adjacent to a periphery of the mold and spaced apart over at least a part of the length prior to a deformation of the mold, and spaced from an upper end of the recess and from a bottom end of the recess, and
- wherein the mold has at least one of:
- the side wall being deprived of recesses opening out into an internal surface of the side wall;
- a cavity with a sloping bottom wall;
- a cavity having a part formed by two successive conical surfaces converging towards an opening of the mold;
- a top portion having a flange;
- a flange surrounding an opening of the mold;
- an opening defined at least partially by a conical surface, the conical surface having an internal surface configured to be in contact with the product, the side wall being deprived of recesses opening out into said internal surface;
- and
- at least one of said recesses extending longitudinally beyond a bottom of an inner cavity of said mold.
A mold for manufacturing a stick, wherein the mold has at least one notch facilitating radial deformation of said mold, said notch having longitudinal edges having a length on an external surface of the mold, the edges comprising portions that are adjacent to a periphery of the mold and spaced apart over at least a part of the length prior to a deformation of the mold, and spaced from an upper end of the recess and from a bottom end of the recess, and said notch having a depth decreasing along a length of said notch towards a bottom end of the mold.
A mold for manufacturing a stick, wherein the mold comprises at least one notch facilitating radial deformation of said mold, said notch having a depth decreasing along a length of said notch towards a bottom end of the mold, and wherein said notches extend longitudinally over substantially an entire height of the mold all the way to the bottom end of the mold.
A mold for manufacturing a stick, wherein the mold has at least one notch facilitating radial deformation of said mold, said notch having longitudinal edges having a length on an external surface of the mold, portions of the edges adjacent to a periphery of the mold being spaced apart over at least a part of the length prior to a deformation of the mold, and said notch having a depth decreasing along a length of said notch towards a bottom end of the mold, wherein the at least one notch extends longitudinally beyond a bottom of an inner cavity of said mold.
