Abstract
Abstract A composite package for holding pressurized fluent materials such as carbonated beverages, beer, aerosols and the like, which includes a thermoplastic container having a hemispherically shaped bottom section and a support for holding the container in an upright position which is formed of a thermoplastic compatible with that of the container, the support being heat sealed to the bottom section so as to attach the two together.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
104 words
A composite package for holding pressurized fluent materials comprising: a. a one piece, elongated thermoplastic container having a substantially hemispherically shaped bottom section to minimize stresses generated thereon by said fluent materials, said bottom section having a projection thereon extending away from the container; b. means for supporting saiD container in an upright position, said means being formed of a thermoplastic which is compatible with the thermoplastic of said container, said means including an end wall having an aperture therein through which said projection extends, said supporting means being heat sealed to said projection in the area of the end wall adjacent said aperture.
Claim 2
Dependent Claim
104 words
A composite package for holding pressurized fluent materials comprising: a. a one piece, elongated thermoplastic container having a substantially hemispherically shaped bottom section to minimize stresses generated thereon by said fluent materials, said bottom section having a projection thereon extending away from the container; b. means for supporting saiD container in an upright position, said means being formed of a thermoplastic which is compatible with the thermoplastic of said container, said means including an end wall having an aperture therein through which said projection extends, said supporting means being heat sealed to said projection in the area of the end wall adjacent said aperture.
Claim 3
Dependent Claim
24 words
The package of claim 1 wherein said projection is on the axis of said container and is between one-sixteenth to one-fourth inch in diameter.
Claim 4
Dependent Claim
26 words
The package of claim 2 wherein said projection has a head portion of greater diameter than the aperture in the end wall of the supporting means.
Claim 5
Dependent Claim
21 words
