Abstract
Abstract A disposable lamp comprising a body, formed of a plastic material for holding a flammable fluid therein and including a mouth onto which is secured a burner-closure assembly. The burner-closure assembly comprises a burner and cap means. The cap means is circular in profile and includes a rolled lip extending about the periphery and having a free edge. The lip includes an underside surface on which gasket means is located. The mouth of the bottle is tubular and includes a bead extending about the periphery of the free edge, which bead includes a pair of peripherally extending tapered edges. The cap is disposed over the mouth of the body with the bead located within the rolled lip and with the rolled lip bent tightly thereabout so that the tapered edges of the bead tightly engage the gasket means to form a fluid-tight seal between the cap means and the body.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
212 words
A container for holding a fluid therein and comprising a hollow body formed of a plastic material and having a mouth and metal closure means secured to said mouth in a fluid-tight seal, said closure means comprising a cap having a circular profile and a rolled lip extending about the periphery thereof and terminating in a free edge, said lip having an underside surface, gasket means located on said underside surface, said mouth being tubular and having a longitudinal axis, said mouth including bead means extending about the periphery of said mouth about said axis and contiguous with the free end of said mouth, said bead means including an arcuate outer surface including an annular recess extending about the periphery of said mouth and forming a pair of generally pointed corners adjacent said arcuate outer surface, each of said corners being directed outwardly away from the longitudinal axis of said container and spaced from each other in the longitudinal direction, said bead means being located within said rolled lip, with said lip being bent tightly thereabout and with the free edge disposed under said bead means, whereupon said corners tightly engage and dig into said gasket means along longitudinally spaced lines to form a fluid-tight seal between said body and said cap.
Claim 2
Dependent Claim
212 words
A container for holding a fluid therein and comprising a hollow body formed of a plastic material and having a mouth and metal closure means secured to said mouth in a fluid-tight seal, said closure means comprising a cap having a circular profile and a rolled lip extending about the periphery thereof and terminating in a free edge, said lip having an underside surface, gasket means located on said underside surface, said mouth being tubular and having a longitudinal axis, said mouth including bead means extending about the periphery of said mouth about said axis and contiguous with the free end of said mouth, said bead means including an arcuate outer surface including an annular recess extending about the periphery of said mouth and forming a pair of generally pointed corners adjacent said arcuate outer surface, each of said corners being directed outwardly away from the longitudinal axis of said container and spaced from each other in the longitudinal direction, said bead means being located within said rolled lip, with said lip being bent tightly thereabout and with the free edge disposed under said bead means, whereupon said corners tightly engage and dig into said gasket means along longitudinally spaced lines to form a fluid-tight seal between said body and said cap.
Claim 3
Dependent Claim
37 words

Claim 5
Dependent Claim
11 words
The container of claim 3 wherein said angle is approximately 80°.
Claim 6
Dependent Claim
12 words
The container of claim 1 wherein said peripheral recess is generally V-shaped.
Claim 7
Dependent Claim
12 words
The container of claim 1 wherein said plastic body is blow molded.
Claim 8
Dependent Claim
19 words
The container of claim 1 wherein said gasket means comprises a coating on the underside surface of said lip.
Claim 9
Dependent Claim
12 words
The container of claim 7 wherein said gasket comprises a water-soluble vinyl.
Claim 10
Dependent Claim
17 words
The container of claim 8 wherein said plastic is a tough, impact resistant, yet somewhat resilient plastic.
Claim 11
Dependent Claim

Claim 14
Independent Claim
223 words
The method of sealing the mouth of a plastic container with a metal closure, said container having a tubular mouth having a longitudinal axis and including bead means extending about the periphery of the mouth contiguous with the free end thereof, said bead means including an arcuate outer surface including an annular recess extending about the periphery of said mouth and forming a pair of generally pointed corners extending about the periphery of said bead means adjacent said arcuate outer surface, each of said corners being directed outwardly away from the longitudinal axis of said container and spaced from each other in the longitudinal direction, said closure means including cap means, circular in profile, and having a roller lip extending about the periphery thereof and terminating in a free edge, said lip having an underside surface upon which gasket means is disposed, said method comprising the steps of disposing said cap means on said mouth and with said bead means located within said lip, disposing lip deforming means over said lip, constricting said lip deforming means in a radial direction to deform said lip around said bead means and causing both of said corners of said bead means to engage and dig into said gasket means along respective longitudinally spaced lines to form a fluid-tight seal between said cap means and said container.
Claim 15
Independent Claim
223 words
The method of sealing the mouth of a plastic container with a metal closure, said container having a tubular mouth having a longitudinal axis and including bead means extending about the periphery of the mouth contiguous with the free end thereof, said bead means including an arcuate outer surface including an annular recess extending about the periphery of said mouth and forming a pair of generally pointed corners extending about the periphery of said bead means adjacent said arcuate outer surface, each of said corners being directed outwardly away from the longitudinal axis of said container and spaced from each other in the longitudinal direction, said closure means including cap means, circular in profile, and having a roller lip extending about the periphery thereof and terminating in a free edge, said lip having an underside surface upon which gasket means is disposed, said method comprising the steps of disposing said cap means on said mouth and with said bead means located within said lip, disposing lip deforming means over said lip, constricting said lip deforming means in a radial direction to deform said lip around said bead means and causing both of said corners of said bead means to engage and dig into said gasket means along respective longitudinally spaced lines to form a fluid-tight seal between said cap means and said container.
