A method for manufacturing a cosmetic stick having at least two different colored portions includes inserting a pin into at least one mold cavity of a mold body, filling the mold cavity containing the pin with a first cosmetic material of a first color, and then recovering the excess first cosmetic material from a top surface of the mold body. The pin is removed from the mold cavity leaving a void in the mold cavity, and a guard plate is placed over the top surface of the mold body, the guard plate having a hole over the mold cavity. The void in the mold cavity is filled with a second cosmetic material, the second cosmetic material being a second color that is different than the first color. The excess second cosmetic material is then recovered from a top surface of the guard plate.

The invention relates to molding of a roller in which a roller body is provided integrally on the outer periphery of an axial core member, and the objective of the invention is to prevent the generation of a thin burr, and damage to the die. In order to achieve this objective, a die is provided with a first split die and a second split die which can butt against one another or separate from one another at mutually-opposing parting surfaces. A roller body molding surface, a cavity being defined between the axial core member and the roller body molding surface when the mold is clamped; and recessed portions which are located at both end portions of the supporting portions and extend along the parting surfaces, and which are not in contact with the outer peripheral surface of the axial core member when the mold is clamped.

The present invention relates to a method for producing a foam molded product, in which in a foaming step, at least a part of a burr is made to be an undercut that is caught in a movable mold portion when mold opening the movable mold portion, in a cross section obtained by cutting a foam intermediate on a plane orthogonal to a direction in which a boundary between a main body and a burr extends, a fragile portion is provided at the boundary such that at least a part of the burr located near the boundary is narrowed toward the boundary, and a foam intermediate is formed, and in a removal step, the fragile portion is broken and the burr is removed by pulling the burr with the movable mold portion.

A method of producing a foamed composite molded product includes fixing an exposed part of an insert material on a fixing part provided in a mold, the insert material being inserted in an in-mold foamed molded product made of a thermoplastic resin; introducing a polyurethane liquid into the mold; and producing the foamed composite molded product by foaming the polyurethane liquid in the mold. The foamed composite molded product includes an in-mold foamed molded product unit including the insert material and the in-mold foamed molded product; and a polyurethane foam. At least part of the insert material is exposed to an outside of the in-mold foamed molded product, and the in-mold foamed molded product unit and the polyurethane foam are integrated.

The following invention is used to recycle broken pieces of crayons, A crayon package comprises a portion of the box which can be placed in an oven, said portion of the box being detachable from the package, said portion of the box is designed as a crayon recycling cartridge, the crayon recycling cartridge comprises slots, the edges of the slots are provided with guide slopes, the bottom of the guide slope is connected to the edge of the slot and the slot is expanded outward, which increases the volume of the slot. The used crayons will be placed into the slots, melted and re-casted into new crayons. And if too much used crayons are placed above the edge of the slots, when the crayon melts, the guide slope will catch the melted crayons, sending it back down into the slots, fitting to the volume of the slots.
