Cosmetic product molding apparatus and method of molding rod-shaped cosmetic product in cosmetic product molding apparatus

A cosmetic product molding apparatus comprising:

• a plurality of molds, each mold of the plurality of molds having a bottomed cylindrical shape and including a cylindrical recessed portion, the cylindrical recessed portion being configured to be filled with a cosmetic composition for a rod-shaped cosmetic product;
• one or more outer cylinders surrounding side surfaces of the plurality of molds;
• a plurality of Peltier elements configured to heat or cool the plurality of molds;
• and
• a controller configured to control each Peltier element of the plurality of Peltier elements to adjust a temperature of each mold of the plurality of molds,
• wherein the one or more outer cylinders are provided so as to prevent the plurality of molds from affecting respective temperatures of fillings of one another,
• wherein each mold of the plurality of molds includes
• an inner mold including the cylindrical recessed portion to be directly filled with the cosmetic composition for the rod-shaped cosmetic product, and
• a thermally conductive mold that has a bottomed cylindrical shape and surrounds a side surface and a lower surface of the inner mold,
• wherein the thermally conductive mold includes
• a holder cylinder that surrounds the side surface and the lower surface of the inner mold, and includes a bottom surface that is not in contact with each Peltier element of the plurality of Peltier elements,
• a thermally conductive outer cylinder that surrounds the holder cylinder so as to be spaced apart from an outer side surface of the holder cylinder, and includes a lower end that contacts at least one Peltier element of the plurality of Peltier elements, and
• a connecting portion configured to connect a vicinity of an upper end of the holder cylinder to a vicinity of an upper end of the thermally conductive outer cylinder.

A cosmetic product molding apparatus comprising:

• a plurality of molds, each mold of the plurality of molds having a bottomed cylindrical shape and including a cylindrical recessed portion, the cylindrical recessed portion being configured to be filled with a cosmetic composition for a rod-shaped cosmetic product;
• one or more outer cylinders surrounding side surfaces of the plurality of molds;
• a plurality of Peltier elements configured to heat or cool the plurality of molds;
• a controller configured to control each Peltier element of the plurality of Peltier elements to adjust a temperature of each mold of the plurality of molds, wherein the one or more outer cylinders are provided so as to prevent the plurality of molds from affecting respective temperatures of fillings of one another;
• and
• an environment sensor configured to measure at least one of an outside air temperature or a humidity of an environment in which the cosmetic product molding apparatus is located,
• wherein the controller includes
• element controllers that are equal in number to the plurality of Peltier elements, each element controller being provided near a corresponding Peltier element of the plurality of Peltier elements, and
• a main controller configured to communicate with each element controller,
• wherein the main controller is configured to adjust and set, based on a detection result from the environment sensor, a temperature for a program for heating or cooling each Peltier element, and to transmit the set temperature to a corresponding element controller of the element controllers, and
• wherein each element controller controls a temperature of the corresponding Peltier element of the plurality of Peltier elements based on the transmitted set temperature.

A method of manufacturing a rod-shaped cosmetic product in a cosmetic product molding apparatus, the cosmetic product molding apparatus including a plurality of bottomed cylindrical-shaped molds, one or more outer cylinders surrounding side surfaces of the plurality of molds, a plurality of Peltier elements, and a controller connected to the plurality of Peltier elements, the method comprising:

• filling a cylindrical recessed portion of each mold of the plurality of molds with a cosmetic composition for a rod-shaped cosmetic product;
• and
• solidifying the cosmetic composition via each mold by a corresponding Peltier element of the plurality of Peltier elements by causing the controller to control the corresponding Peltier element of the plurality of Peltier elements to adjust a temperature of each mold of the plurality of molds,
• wherein in the solidifying of the cosmetic composition, the one or more outer cylinders are provided so as to prevent the plurality of molds from affecting respective temperatures of fillings of one another.
