Abstract
Abstract A dispensing container is disclosed herein with an improved collapsible pouring spout. The container, preferably a blow molded container, has at least one side wall with a nestable dispensing spout secured thereto. Most preferably a wall, top and spout are integral having been blow molded with a bottom being provided by way of a metal cap or the like and applied during the filling operation. Initially the pouring spout is nested within the container and is extractable to a dispensing position. The nestable dispensing spout has a bellows section therealong about which the spout partially everts from a nested to an extended position and vice versa, with the bellows section containing a series of progressively smaller pleats from bottom to top. At least certain of the pleats have circumferentially compressible sections therearound which may be protrusions, detents or both. The protrusions and/or detents permit a circumferential compression and thus a reduction of an outside or inside diameter of same, depending upon the type section that is employed. Partial eversion of the spout is thus fostered. A cover is secured to the top of the pouring spout and is removeable therefrom to permit dispensing. The cover may be adapted to be replaceable after removal from the spout to reclose and/or reseal same.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
112 words
An improved dispensing container comprising: (a) a body; and (b) a dispensing spout secured to said body and being nestable within said body, said spout including a tapered portion extending outwardly from said body and having a plurality of circumferential pleats therealong whereby said tapered portion of said spout partially everts during nesting and withdrawal of said spout, at least one of said circumferential pleats including at least one means located along the circumference of same that extends generally radially with respect thereto, said at least one means being circumferentially compressible during eversion of said spout to circumferentially reduce said at least one pleat to facilitate nesting and withdrawal of said spout.
Claim 2
Dependent Claim
112 words
An improved dispensing container comprising: (a) a body; and (b) a dispensing spout secured to said body and being nestable within said body, said spout including a tapered portion extending outwardly from said body and having a plurality of circumferential pleats therealong whereby said tapered portion of said spout partially everts during nesting and withdrawal of said spout, at least one of said circumferential pleats including at least one means located along the circumference of same that extends generally radially with respect thereto, said at least one means being circumferentially compressible during eversion of said spout to circumferentially reduce said at least one pleat to facilitate nesting and withdrawal of said spout.
Claim 3
Dependent Claim
17 words
The container as defined in claim 1 wherein said body and said spout are of unitary construction.
Claim 4
Dependent Claim
28 words
The container as defined in claim 1 wherein said means are compressible sections that project from said pleat and reduce an inside diameter of said pleat during compression.
Claim 5
Dependent Claim
26 words
The container as defined in claim 1 wherein said means are compressible sections that are detents and reduce an outside diameter of said pleat during compression.
Claim 6
Dependent Claim
27 words
The container as defined in claim 1 wherein certain pleats have means that are compressible projecting sections and certain pleats have means that are compressible detent sections.
Claim 7
Dependent Claim
17 words
The container as defined in claim 5 wherein the compressible means are equally spaced around the pleats.
Claim 8
Dependent Claim
15 words
The container as defined in claim 1 wherein said spout has a removable cover thereon.
Claim 9
Dependent Claim
22 words
The container as defined in claim 7 wherein the cover is replaceable over an end of said spout to reclose said spout.
Claim 10
Dependent Claim
111 words
An improved dispensing container comprising: (a) a body; (b) a top wall integral with said body; and (c) a dispensing spout integral with said top wall and including a tapered, circumferentially pleated portion extending outwardly from said top wall whereby application of axial force along said spout to nest or withdraw said spout causes eversion of the tapered spout portion, at least one of said pleats having at least one means around the circumference thereof that extends generally radially with respect thereto, said at least one means being circumferentially compressible during eversion of said spout to circumferentially reduce said at least one pleat to facilitate nesting and withdrawal of said spout.
Claim 11
Dependent Claim
111 words
An improved dispensing container comprising: (a) a body; (b) a top wall integral with said body; and (c) a dispensing spout integral with said top wall and including a tapered, circumferentially pleated portion extending outwardly from said top wall whereby application of axial force along said spout to nest or withdraw said spout causes eversion of the tapered spout portion, at least one of said pleats having at least one means around the circumference thereof that extends generally radially with respect thereto, said at least one means being circumferentially compressible during eversion of said spout to circumferentially reduce said at least one pleat to facilitate nesting and withdrawal of said spout.
Claim 12
Dependent Claim
24 words
The container as defined in claim 9 wherein said means are compression sections that are projections from said at least certain of said pleats.
Claim 13
Dependent Claim
13 words
The container as defined in claim 10 wherein the projections are pyramidal shaped.
Claim 14
Dependent Claim
24 words
The container as defined in claim 9 wherein said means are compression sections that are detents into said at least certain of said pleats.
Claim 15
Dependent Claim
14 words
The container as defined in claim 12 wherein the detent sections are pyramidal shaped.
Claim 16
Dependent Claim
31 words
The container as defined in claim 9 wherein certain of said pleats have means that are compressible projecting sections and certain of said pleats have means that are compressible detent sections.
