Reducing indentation in a label included on the exterior surface of an injection-molded product |
摘要 |
A hollow injection-molded product has a sidewall that is formed in a mold cavity by injecting molding material. An interior surface of the sidewall includes at least one ridge that is shaped by a flow channel in the mold cavity. The flow channel directs the flow of the injected molding material in the mold cavity. The cross-sectional dimension of the ridge normal to the direction of flow of the molding material that is injected in the flow channel generally decreases in the direction of flow. A label is inserted into the mold cavity prior to injection of the molding material so that the label is on the exterior surface of the sidewall of the hollow product. |

1. A process of reducing or eliminating an indentation in a label included on an exterior surface of a sidewall of an injected molded hollow product, wherein a portion of an interior surface of the product sidewall that is opposite the label includes at least one ridge, the process comprising the steps of:
(a) providing a mold cavity including at least one flow channel that directs flow of the injected molding material in the mold cavity to form a hollow product having a sidewall, wherein an interior surface of the product sidewall includes at least one ridge shaped by the flow channel in the mold cavity; (b) inserting a label into the mold cavity so that the label will be included on the exterior surface of the sidewall of the injection-molded product; and (c) injecting molding material into the mold cavity to form the product; wherein step (a) comprises the step of: (d) shaping the flow channel so that a cross-sectional dimension of the ridge normal to the direction of flow of the molding material in the flow channel generally decreases in the direction of flow. |
