Abstract
Abstract A decanter for use with a beverage, such as coffee, having a pouring spout provided with a mounting portion carrying a suitable handle. The mounting structure is sealingly secured to the neck of the decanter by compressive engagement with a seal ring set in place about the neck of the decanter below the upper edge thereof. The seal ring is compressed both axially and radially as a result of the engagement therewith by a stepped portion of the bore of the mounting structure. The mounting structure is retained against axial displacement from the installed condition wherein the seal is thusly compressed by an interlock at the lower end of the mounting structure and a cooperating portion on the decanter neck. An upper, inturned flange on the mounting structure is spaced slightly above the upper edge of the decanter neck in the installed arrangement of the spout on the decanter.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
195 words
In a decanter structure having a glass bowl provided with an upstanding tubular neck terminating in an upper edge, a pouring spout, annular mounting means on said pouring spout for mounting said pouring spout on said neck, said mounting means defining an upper radially inwardly projecting shoulder overlying said upper edge of the neck, means having a first portion on the neck spaced below said upper edge, and a second portion on said annular mounting means for interlocking the pouring spout removably to the neck, and a handle connected to said mounting means, the improvement comprising means defining an annular set-in-place resilient seal extending about said neck intermediate said upper edge and said first portion of the interlocking means, said seal being formed of an adhesive material preselected to be effectively positively sealingly bonded to said neck as a result of setting thereof in place on said neck, said mounting means being removably installed about the set annular seal, said seal being maintained in both radially and axially compressed sealed engagement therewith and said shoulder being spaced above said upper edge of said neck by said means for interlocking the pouring spout to the neck.
Claim 2
Dependent Claim
195 words
In a decanter structure having a glass bowl provided with an upstanding tubular neck terminating in an upper edge, a pouring spout, annular mounting means on said pouring spout for mounting said pouring spout on said neck, said mounting means defining an upper radially inwardly projecting shoulder overlying said upper edge of the neck, means having a first portion on the neck spaced below said upper edge, and a second portion on said annular mounting means for interlocking the pouring spout removably to the neck, and a handle connected to said mounting means, the improvement comprising means defining an annular set-in-place resilient seal extending about said neck intermediate said upper edge and said first portion of the interlocking means, said seal being formed of an adhesive material preselected to be effectively positively sealingly bonded to said neck as a result of setting thereof in place on said neck, said mounting means being removably installed about the set annular seal, said seal being maintained in both radially and axially compressed sealed engagement therewith and said shoulder being spaced above said upper edge of said neck by said means for interlocking the pouring spout to the neck.
Claim 3
Dependent Claim
36 words
The decanter structure of claim 1 wherein said mounting means includes an annular downwardly facing, radially inwardly projecting shoulder engaging said seal in the installed relationship thereof to effect said maintained axial compression of the seal.
Claim 4
Dependent Claim
86 words
The decanter structure of claim 1 wherein said mounting means defines a stepped bore having an upper portion and a lower portion, said upper portion having a smaller diameter than that of said lower portion to define an annular shoulder therebetween, said seal having a first, lower portion compressed radially in said lower portion of the mounting means with a first compressive sealing force and a second, upper portion compressed radially in said upper portion of the mounting means with a second higher compressive sealing force.
Claim 5
Dependent Claim
109 words
The decanter structure of claim 1 wherein said mounting means defines a stepped bore having an upper portion and a lower portion, said upper portion having a smaller diameter than that of said lower portion to define an annular shoulder therebetween, said seal having a first, lower portion compressed radially in said lower portion of the mounting means with a first compressive sealing force and a second, upper portion compressed radially in said upper portion of the mounting means with a second higher compressive sealing force, said mounting means further defining an uppermost inturned shoulder for effectively positively limiting the downward movement of the mounting means against said seal.
Claim 6
Dependent Claim
16 words
The decanter structure of claim 1 wherein said shoulder comprises a radially inwardly projecting annular shoulder.
Claim 7
Dependent Claim
20 words
The decanter structure of claim 1 wherein the outer surface of the undeformed seal is substantially semicircular in cross section.
Claim 8
Dependent Claim
15 words
The decanter structure of claim 1 wherein said seal is formed of RTV silicone adhesive.
