The present disclosure relates to a pacifier. More particularly, the disclosure relates to an apparatus and method for a hygienic pacifier.
Throughout the various figures, like reference numbers refer to like elements.
Although any suitable method can be used in forming the hygienic pacifier, particular advantage can be achieved when the pacifier is formed via an injection molding process. A method in accordance with the principles herein includes the steps of forming a unitary, hygienic pacifier using a suitable material to provide a shield capable of recoiling from an in use toroidal position, to a spherical storage position. To this end, a suitable material, such as, for example, medical grade silicone, can be formed by a suitable process, such as by injection molding, to form a unitary device including a shield having a wall. The wall of the shield is formed by the process to enable sufficient recoil of the device from a use position to a storage position, without rendering the device too springy to function in the use position. To this end, various suitable materials can be manipulated to produce recoil properties to ensure functionality of the device. Advantageously, flexible spheres that can automatically retract the nipple of the pacifier due to the varied thickness and resiliency of the material of the unitary device are achieved in accordance with the principles herein. The design eliminates the need to apply external forces to retract the nipple to achieve a storage position. Additionally, the shape of a device constructed in accordance with the principles herein is ergonomic, making the structure easier to use for children with limited movement.
For example, a typical wall thickness for medical grade silicone is in the range of 1.5 to 2 mm. In accordance with the principles herein, the base and nipple of the device are formed at the typical thickness, whereas the shield wall can be reduced down to approximately 0.7 to 1 or 1.5 mm thickness, and the thickness can vary across the structure by increasing in thickness as the material transitions to the end of the sphere nearest the faceplate. Further, the thickness of the faceplate can range from 2 mm up to approximately 7 mm. It will be understood to those of skill in the art that the relative reduction in thickness may need to be adjusted depending on the recoil characteristics of various materials.
For each material considered, a balance between obtaining the thickest wall possible while retaining the recoil functionality of the device must be considered. Further, the distance between the nipple and the shield wall can be adjusted to vary the suction characteristics of the device. In additional steps, a lanyard may be attached to slits or holes provided in the device. Colorant may also be added to the material while forming the device. The device can be textured on the exterior to prevent artifacts, such as lint, from adhering to the silicone surface. Further, the spherical shape of the shield eliminates crevices in known devices that can house dirt or debris. While the embodiments disclosed herein are exemplary, various changes and modifications can be made without departing from the spirit and scope of the present disclosure.
This application is a continuation of U.S. patent application Ser. No. 13/956,232 filed Jul. 31, 2013, which claims priority from U.S. provisional application No. 61/678,078 filed Jul. 31, 2012, the disclosures of which are incorporated by reference herein.
