Abstract
Abstract This invention contemplates a liquid-sealing assembly of a liquid-dispensing fitting to the open tubular end of a container body, and featuring ease of automated assembly, as well as effectiveness of the seal, even when the fitting is a threaded part which is necessarily subjected to reaction torque with respect to the container body, for each opening and closing of the container. A relatively soft yieldable bushing is radially compressed to permanently retain and seal the assembly, and the proportions of fitted parts are such that seal-effectiveness and appearance cannot be impaired in the course of automated assembly.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
201 words
In a container for liquid cosmetic or the like substance, a body having a tubular open end, a flanged cylindrical tubular bushing of relatively yieldable material received in said open end to an extent aXially limited by the flanged portion of said bushing, and a flanged relatively stiff dispensing fitting including an upwardly extending threaded neck with an internal passage open at both axial ends, said fitting having a tubular sleeve received in said bushing to an extent axially limited by the flanged portion of said fitting, said bushing having an unstressed external cylindrical diameter less than the bore diameter of the tubular open end in which it is received, whereby bushing sub-assembly to said body is essentially frictionless, and said sleeve having an external cylindrical diameter greater than the unstressed bore diameter of said bushing and being chamfered at the lower end, whereby assembly of said fitting to the sub-assembled bushing and body is a force-fit in which said bushing is radially expanded, the extent of sleeve-to-bushing interference being such in relation to the unstressed clearance of the subassembled parts that said bushing is radially compressionally loaded in circumferentially continuous engagement with the body bore upon assembly of said fitting.
Claim 2
Dependent Claim
201 words
In a container for liquid cosmetic or the like substance, a body having a tubular open end, a flanged cylindrical tubular bushing of relatively yieldable material received in said open end to an extent aXially limited by the flanged portion of said bushing, and a flanged relatively stiff dispensing fitting including an upwardly extending threaded neck with an internal passage open at both axial ends, said fitting having a tubular sleeve received in said bushing to an extent axially limited by the flanged portion of said fitting, said bushing having an unstressed external cylindrical diameter less than the bore diameter of the tubular open end in which it is received, whereby bushing sub-assembly to said body is essentially frictionless, and said sleeve having an external cylindrical diameter greater than the unstressed bore diameter of said bushing and being chamfered at the lower end, whereby assembly of said fitting to the sub-assembled bushing and body is a force-fit in which said bushing is radially expanded, the extent of sleeve-to-bushing interference being such in relation to the unstressed clearance of the subassembled parts that said bushing is radially compressionally loaded in circumferentially continuous engagement with the body bore upon assembly of said fitting.
Claim 3
Dependent Claim
201 words
In a container for liquid cosmetic or the like substance, a body having a tubular open end, a flanged cylindrical tubular bushing of relatively yieldable material received in said open end to an extent aXially limited by the flanged portion of said bushing, and a flanged relatively stiff dispensing fitting including an upwardly extending threaded neck with an internal passage open at both axial ends, said fitting having a tubular sleeve received in said bushing to an extent axially limited by the flanged portion of said fitting, said bushing having an unstressed external cylindrical diameter less than the bore diameter of the tubular open end in which it is received, whereby bushing sub-assembly to said body is essentially frictionless, and said sleeve having an external cylindrical diameter greater than the unstressed bore diameter of said bushing and being chamfered at the lower end, whereby assembly of said fitting to the sub-assembled bushing and body is a force-fit in which said bushing is radially expanded, the extent of sleeve-to-bushing interference being such in relation to the unstressed clearance of the subassembled parts that said bushing is radially compressionally loaded in circumferentially continuous engagement with the body bore upon assembly of said fitting.
Claim 4
Dependent Claim
201 words
In a container for liquid cosmetic or the like substance, a body having a tubular open end, a flanged cylindrical tubular bushing of relatively yieldable material received in said open end to an extent aXially limited by the flanged portion of said bushing, and a flanged relatively stiff dispensing fitting including an upwardly extending threaded neck with an internal passage open at both axial ends, said fitting having a tubular sleeve received in said bushing to an extent axially limited by the flanged portion of said fitting, said bushing having an unstressed external cylindrical diameter less than the bore diameter of the tubular open end in which it is received, whereby bushing sub-assembly to said body is essentially frictionless, and said sleeve having an external cylindrical diameter greater than the unstressed bore diameter of said bushing and being chamfered at the lower end, whereby assembly of said fitting to the sub-assembled bushing and body is a force-fit in which said bushing is radially expanded, the extent of sleeve-to-bushing interference being such in relation to the unstressed clearance of the subassembled parts that said bushing is radially compressionally loaded in circumferentially continuous engagement with the body bore upon assembly of said fitting.
