Abstract
Abstract A spout has a resilient and flexible tubular body which is produced by dipping a heated mold into polyvinyl chloride to form a coating or layer. The layer is cured within an oven and then cooled and removed from the mold. The spout body includes a base inlet portion which is stretched onto or pressed into the annular threaded neck or outlet portion of a liquid container to retain the body and to form a liquid-tight seal. The internal passage defined by the tubular body is closed by the user pinching the body with his fingers after which the container is inverted, and the pinch is released to control the dispensing of the liquid from the container. Interchangeable hollow tip members are also produced by dip-molding, and each tip member is pressed onto the outlet end portion of the tubular body to form a cap or smaller discharge opening.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
160 words
A pouring and dispensing spout in combination with a liquid container having a tubular neck portion with external helical threads and a circular surface adjacent said threads, said spout including an elongated one-piece and dip-molded tubular body of resilient and flexible rubber-like material and defining an internal passage, said body having a generally uniform wall thickness and including an enlarged annular inlet portion and a smaller annular outlet portion, said inlet portion having a removable friction engagement with said neck portion of said container and adapted to be pressed axially onto said neck portion, said inlet portion of said body also having a peripherally extending annular rib forming a liquid-tight seal with said circular surface of said neck portion, and said body having an annular intermediate wall portion which collapses to close said passage in response to pinching said wall portion with a user's fingers to permit inverting said container and then controlled dispensing of the liquid from said container.
Claim 2
Dependent Claim
160 words
A pouring and dispensing spout in combination with a liquid container having a tubular neck portion with external helical threads and a circular surface adjacent said threads, said spout including an elongated one-piece and dip-molded tubular body of resilient and flexible rubber-like material and defining an internal passage, said body having a generally uniform wall thickness and including an enlarged annular inlet portion and a smaller annular outlet portion, said inlet portion having a removable friction engagement with said neck portion of said container and adapted to be pressed axially onto said neck portion, said inlet portion of said body also having a peripherally extending annular rib forming a liquid-tight seal with said circular surface of said neck portion, and said body having an annular intermediate wall portion which collapses to close said passage in response to pinching said wall portion with a user's fingers to permit inverting said container and then controlled dispensing of the liquid from said container.
Claim 3
Dependent Claim
27 words
The combination defined in claim 1 wherein said annular rib projects radially inwardly to engage said circular surface of said neck portion to form said liquid-tight seal.
Claim 4
Dependent Claim
15 words
The combination defined in claim 1 wherein said one-piece tubular body comprises polyvinyl chloride material.
Claim 5
Dependent Claim
42 words
The combination defined in claim 1 wherein said inlet portion of said body projects into said neck portion of said container, and said annular rib projects radially outwardly to engage said circular surface of said neck portion to form said liquid-tight seal.
Claim 6
Dependent Claim
24 words
The combination in claim 4 wherein said inlet portion of said tubular body has a center axis and a corrugated configuration in axial cross-section.
Claim 7
Dependent Claim
56 words
The combination defined in claim 1 and including a dip-molded tip member of resilient and flexible rubber-like material, said tip member having a substantially uniform wall thickness and surrounding said outlet portion of said body in removable friction engagement, and said tip member defines a discharge opening substantially smaller than said outlet portion of said body.
Claim 8
Dependent Claim
34 words
The combination defined in claim 6 wherein said tip member includes a tubular discharge portion defining said discharge opening and projecting at an acute angle with respect to the axis of said tubular body.
Claim 9
Independent Claim
187 words
A method of dispensing a liquid from a container having an annular neck portion defining an outlet and having external helical threads adjacent a circular surface, comprising the steps of heating an elongated mold, dipping the mold into a liquid plastics material to form a layer on the mold, curing the layer with heat, stripping the layer from the mold to form an elongated one-piece tubular spout body of resilient and flexible rubber-like material, the body defining a passage and including an enlarged annular inlet end portion and a smaller annular outlet end portion and with the inlet end portion having a peripherally extending annular rib, pressing the inlet end portion of the body axially with respect to the neck portion of the container with the inlet end portion forming a friction engagement with the neck portion and the annular rib forming a liquid-tight seal with the circular surface of the neck portion, pinching the tubular body to close the passage, at least partially inverting the container and spout, and releasing the pinching of the body to permit liquid to flow from the container through the spout.
