Abstract
Abstract A generally cylindrical container is symmetrical both axially and radially and has an opening at opposite longitudinal ends for dispensing its contents. The interior of the container is tapered at either end into pouring spouts, while the exterior is tapered slightly inwardly toward the middle of the container for easier grasping and has broad end sections for stable standing and stacking on end. Increased wall thickness at either end weights the container to increase stability in an upright position. End caps screw onto the container over the end openings thereof, sealing against leakage.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
200 words
A generally cylindrical, hollow container having a longitudinal axis and being bilaterally symmetric about a median plane normal to said axis, said container comprising: a solid circumferential wall forming said container with an outer peripheral surface and a hollow therewithin at an inner peripheral surface thereof, said wall being radially thicker near opposite longitudinal extremities of said container and radially thinner near said median plane, thereby to form a weighted end for promoting support stability, said outer peripheral surface being tapered concavely inwardly toward said median plane from said ends, and said inner peripheral surface tapering to reduced cross-section at each of said ends at openings therein, said wall further having a flat axial surface on each said end about said opening; engagement means forming a coupling adjacent each said flat surface; a closure member connected to each respective coupling, each of said closure members having a flat closure surface extending radially across said axial opening forming a support surface by means of which the containers may be positioned uprightly on a support surface; and sealing means between said wall and said closure member engaging said axial wall and said closure member about said opening to form a liquid-tight seal.
Claim 2
Dependent Claim
200 words
A generally cylindrical, hollow container having a longitudinal axis and being bilaterally symmetric about a median plane normal to said axis, said container comprising: a solid circumferential wall forming said container with an outer peripheral surface and a hollow therewithin at an inner peripheral surface thereof, said wall being radially thicker near opposite longitudinal extremities of said container and radially thinner near said median plane, thereby to form a weighted end for promoting support stability, said outer peripheral surface being tapered concavely inwardly toward said median plane from said ends, and said inner peripheral surface tapering to reduced cross-section at each of said ends at openings therein, said wall further having a flat axial surface on each said end about said opening; engagement means forming a coupling adjacent each said flat surface; a closure member connected to each respective coupling, each of said closure members having a flat closure surface extending radially across said axial opening forming a support surface by means of which the containers may be positioned uprightly on a support surface; and sealing means between said wall and said closure member engaging said axial wall and said closure member about said opening to form a liquid-tight seal.
Claim 3
Dependent Claim
21 words
A container as defined in claim 1, wherein said sealing means comprises a gasket material affixed to each said closure member.
Claim 4
Dependent Claim
40 words
A container as defined in claim 1, wherein each said closure member carries an axially-disposed plug having a side wall tapered toward said median plane of said container, each said plug engaging said wall of said container in said opening.
Claim 5
Dependent Claim
32 words
A container as defined in claim 1, wherein said engagement means for engaging said closure member comprises a male screw-threaded portion and said closure member comprises a female screw-threaded member cooperable therewith.
Claim 6
Dependent Claim
40 words
A container as defined in claim 1, where said axial end surfaces are flat and parallel to one another, thereby to form a stable base for a pair of containers placed end to end without end caps for contents consolidation.
Claim 7
Dependent Claim
42 words
A container as defined in claim 1, wherein each of said closure members has a flat outer surface opposite said sealing means, thereby to form stable bases for said container and for stacking an additional container atop the container for storage thereof.
