Abstract

Abstract A fastening insert adapted to be molded into the wall of a plastic container in order to provide a flat, fluid-tight sealing surface on the outer surface of the wall. The insert comprises a rigid annular base and a rigid rib which extends axially outward from the base. A plurality of threaded connectors are provided on the insert. The rigid rib and base prevent the plastic material from shrinking and sagging around the connectors during the plastic curing process.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 109 words
A rigid fastening insert adapted to be molded into and embedded in the apertured wall of a molded plastic article, for fastening an object to the wall so that it communicates through the aperture from one side of the wall to the other, and reinforcing the wall to provide a substantially flat, fluid-tight sealing surface around the aperture where the object is to be fastened, said fastening insert comprising: a rigid annular base adapted to surround the aperture; a rigid raised rib integral with and projecting axially from said base; and connecting means secured to said base and said rib and adapted to fasten the object to the wall.
Claim 2
Dependent Claim 109 words
A rigid fastening insert adapted to be molded into and embedded in the apertured wall of a molded plastic article, for fastening an object to the wall so that it communicates through the aperture from one side of the wall to the other, and reinforcing the wall to provide a substantially flat, fluid-tight sealing surface around the aperture where the object is to be fastened, said fastening insert comprising: a rigid annular base adapted to surround the aperture; a rigid raised rib integral with and projecting axially from said base; and connecting means secured to said base and said rib and adapted to fasten the object to the wall.
Claim 3
Dependent Claim 110 words
In a molded plastic article having an apertured wall adapted to be fastened to an object which communicates through the aperture from one side of the wall to the other, an improved fastening insert molded into and embedded in said wall for fastening an object to and reinforcing said wall to provide a substantially flat, fluid-tight sealing surface around said aperture where the object is to be fastened, said fastening insert comprising: a rigid annular base surrounding said aperture; a rigid raised rib integral with and projecting axially from said base; and connecting means secured to said base and said rib and adopted to fasten the object to said wall.
Claim 4
Dependent Claim 110 words
In a molded plastic article having an apertured wall adapted to be fastened to an object which communicates through the aperture from one side of the wall to the other, an improved fastening insert molded into and embedded in said wall for fastening an object to and reinforcing said wall to provide a substantially flat, fluid-tight sealing surface around said aperture where the object is to be fastened, said fastening insert comprising: a rigid annular base surrounding said aperture; a rigid raised rib integral with and projecting axially from said base; and connecting means secured to said base and said rib and adopted to fasten the object to said wall.
Claim 5
Dependent Claim 17 words
