FIG. 2A is a perspective view of the pouring member 20, and FIG. 2B is a center sectional view of the pouring member 20. As shown in FIGS. 2 (a) and 2 (b), the elongate ejection nozzle 21 of the ejection member 20 of the extrusion container 40 according to the present invention has the ejection nozzle in both directions from the center axis to the outside. A flat spatula 24 along the longitudinal direction of 21
Are integrally formed. The spatula 24 may be provided in one direction, that is, only one side in FIG. The spatula 24 is for spreading the content squeezed out from the spout 12 on the application surface, and its outer edge has a smooth curved shape, and particularly has a soft shape hitting human skin. I have it.

As shown in FIG. 2B, the spouting member 20 is integrally formed of a relatively hard thermoplastic resin at an inner portion indicated by an oblique line on the inner side and formed by an elastomer at an E portion indicated by an outer dot. Have been. The outer portion may not be as shown in FIG. 2B, and at least only the portion of the spatula 24 may be an elastomer. The spatula 14 is formed of an elastomer because the elastomer softens the contact with the spatula 24 and easily adapts to the change in the surface shape when the content is spread over the application surface having a complicated shape, and the uniform application is achieved. This is to make it possible.

In order to integrally mold such a single part with two kinds of plastic materials, a two-color molding method can be suitably used. In the two-color molding method, an intermediate molded product obtained by injecting a first plastic material into a first cavity is transferred into a second cavity, and a second plastic material is injected. Multi-stage injection molding in which the above plastic material is fused in a mold. In place of this method, an intermediate product formed by the first mold and the first plastic material is once removed from the mold, inserted into the second mold, and then injected with the second plastic material. Insert molding (in-mold molding) may be performed. The portion where the above two types of plastic materials are fused in the mold is the boundary surface between the hatched portion and the dot portion in FIG. 2B, and the area of the boundary surface where both plastic materials meet at this portion. Is preferably large in order to increase the bonding strength. In some cases, an interface having an uneven shape may be formed. The shape of this interface may be appropriately determined at the stage of designing the first and second molds.
