Abstract
Abstract A pacifier having a rigid safety shield formed of non-resilient material integrally formed with a nipple and ring of soft conventional rubber-like pacifier material wherein the rigid shield is located in a molding cavity in the form of a pacifier, an interference member is axially disposed through the shield, nipple and the ring section of the cavity and thermosetting or thermoplastic material is injection molded into the cavity to rigidly retain the rigid shield member and form an integral pacifier.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
166 words
A process for making a pacifier comprising the steps of: (a) forming a rigid shield having a centrally disposed hole and an array of holes concentrically arranged around the centrally disposed hole; (b) locating the rigid shield member in an injection molding cavity configured in the form of a pacifier which has a ring, nipple, and shield, said shield being located in a section of the cavity between the ring and nipple section with the holes in the shield arranged to provide communication between the ring and nipple sections of the cavity; (c) locating an interference member within the cavity spaced apart from the edge of the centrally disposed hole in the rigid shield and extending axially from the rigid shield through the ring section and into the nipple section; and (d) injecting material from the group comprising thermosetting and thermoplastic material into the cavity to fill the ring and nipple section and to pass through the holes of the shield to retain the shield captive.
Claim 2
Dependent Claim
166 words
A process for making a pacifier comprising the steps of: (a) forming a rigid shield having a centrally disposed hole and an array of holes concentrically arranged around the centrally disposed hole; (b) locating the rigid shield member in an injection molding cavity configured in the form of a pacifier which has a ring, nipple, and shield, said shield being located in a section of the cavity between the ring and nipple section with the holes in the shield arranged to provide communication between the ring and nipple sections of the cavity; (c) locating an interference member within the cavity spaced apart from the edge of the centrally disposed hole in the rigid shield and extending axially from the rigid shield through the ring section and into the nipple section; and (d) injecting material from the group comprising thermosetting and thermoplastic material into the cavity to fill the ring and nipple section and to pass through the holes of the shield to retain the shield captive.
Claim 3
Dependent Claim
19 words
