Method of forming a head plate and formation of oral care implement using the same

摘要

A method of forming a head plate for enhanced cleaning action during brushing. In one embodiment, the invention can be a method of forming a head plate comprising: a) forming a mounting plate comprising a first section and a second section, the first section separated from the second section by a gap, a groove formed into the second section that extends from the gap to a cleaning element location; b) positioning the mounting plate in a mold cavity; c) injecting a molten resilient material into the mold cavity so that the molten resilient material: (1) flows into the gap; (2) flows into the groove; and (3) flows into a cleaning element chamber; and d) solidifying the molten resilient material, the solidified resilient material in the gap coupling the first and second sections of the plate together, the solidified resilient material in the cleaning element chamber forming a first resilient tooth cleaning element.

1. A method of forming a head plate having one or more tooth cleaning elements, the method comprising:
a) forming a mounting plate, the mounting plate comprising a first section and a second section, the first section separated from the second section by a first gap, a first groove formed into a front surface of the second section that extends from the first gap to a cleaning element location of the second section; b) positioning the mounting plate in a mold cavity so that a first cleaning element chamber of the mold cavity is aligned with the cleaning element location; c) injecting a molten resilient material into the mold cavity so that the molten resilient material: (1) flows into the first gap; (2) flows into the first groove; and (3) flows into the first cleaning element chamber; and d) cooling to solidify the molten resilient material, wherein the solidified resilient material in the first gap forms a first resilient hinge that couples the first and second sections of the mounting plate together while the solidified resilient material in the first cleaning element chamber forms a first resilient tooth cleaning element extending from the front surface of the second section of the mounting plate at the cleaning element location.
