| 20090252969 | Product having injection molded portion, method of manufacturing the product, and apparatus for manufacturing the product - A molded product includes an already-formed member and an injection molded portion. The already-formed member, which has a joining surface, is placed in an injection molding mold, and the joining surface and the injection molding mold define a molding cavity. The injection molding mold further defines a spill cavity that is in communication with the molding cavity. Liquid molding material is injected into the molding cavity. At least some of initial molding material which has initially reached the joining surface flows into the spill cavity due to injection pressure of subsequent molding material injected after injection of the initial molding material, and is replaced with the subsequent molding material, which has a temperature higher than that of the initial molding material and a viscosity lower than that of the initial molding material. When the liquid molding material hardens to form an injection molded portion joined to the joining surface of the first already-formed member, the first already-formed member and the injection molded portion are a joined molded product. | 10-08-2009 |
| 20090169821 | Molded product and method of manufacturing the same - A molded product includes a matrix formed of a polymer material and a plurality of capsules dispersed in the matrix. An unevenness is formed on a surface due to expansion of the capsules. Some of the capsules have expanded without bursting and include an exposed outer shell portion that protrudes from a surface, and/or some of the capsules have burst and include an outer shell protruding portion that protrudes outward from the surface. Finish processing is performed, which eliminates the outer shell protruding portions and/or the exposed outer shell portions from the surface. This results in a molded product in which a color difference due to frequency of contacting an object, etc. is not easily generated | 07-02-2009 |
| 20090166366 | Container having handling hole for transportation and opening and closing member for handling hole and manufacturing method for the same - A main body of an opening and closing member is arranged so as to cover a handling hole from one side of a wall, such as a container wall. The opening and closing member is mounted to the container by engaging an engagement portion with a flange formed at the periphery of the handling hole. When a user inserts a hand into the handling hole and pushes the main body, the main body moves away from the wall, and the handling hole is uncovered. By so doing, the user can insert his or her hand into the handling hole and carry the container or other object. Then, when the user removes his or her hand from the handling hole, the main body moves toward the wall, and an outer periphery of the main body contacts the wall at the periphery of the handling hole and returns to the original position. Thus, the handling hole is covered from one side of the wall. By so doing, dirt, water and/or the like can be suppressed from passing through the handling hole. Thus, the container or other object can easily be carried by using the handling hole, and dirt, water and/or the like can be suppressed from passing through the handling hole without requiring a special operation or task. | 07-02-2009 |
| 20090113691 | Apparatus for assembling flexible molding main body part and cover part as molding - A molding, such as a belt-line window molding for a motor vehicle, is produced by assembling or mating a cover part to at least a flexible portion of a functional main body part. A flexible portion of the functional main body part of the molding is compressed and forced into a substantially C-shaped decorative or ornamental cover part, such as a substantially non-flexible metal cover part of a belt-line window molding for a motor vehicle, the flexible and elastic properties of the flexible main body part facilitating an assembly process. An apparatus is provided to retain the cover part during an assembly process ensuring that the cover part is not bent or otherwise excessively deformed during the assembly process, and provides a pushing force to compress or otherwise manipulate the flexible main body part as required to effect assembly of the two-piece belt-line window molding for a motor vehicle. | 05-07-2009 |
