Abstract
Abstract A beverage container provided with unique pressure relief valve means designed to permit the escape of gaseous pressure that may build up within the container as through the inclusion of dry ice therein. The container also includes an interior container which is raised from the bottom of the primary container and includes interior finger-pull abutments. The inner container is designed for slipping downwardly into the interior of the outer container only a predetermined distance, this before a wedging effect occurs; thus, the bottom of the inner container is spaced above the bottom of the outer container so as to lessen chances of fracturing or cracking of the bottom of the outer container when dry ice is disposed in the inner container.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
168 words
A beverage container including, in combination, an outer container having a manually actuatable drain valve, a lid secured to and over said outer container, said lid including a gaseous pressure-relief valve, wherein said lid includes mutually spaced outer and inner walls, said inner wall being provided with airpassageway means, said relief valve being cooperatively disposed with respect to said outer wall, and wherein said outer and inner walls of said lid include aligned apertures, said pressure-relief valve comprising a valve disc centrally disposed over said aligned apertures and itself having a central aperture, said outer wall including at least one additional aperture disposed under said valve disc, elongate means disposed through said aligned apertures of said lid and said central aperture of said disc and having upper and lower reaction means, said lower reaction means coacting against said inner wall of said lid, and compression spring means disposed coaxially about said elongate means and operatively positioned between said upper reaction means and said outer wall of said lid.
Claim 2
Dependent Claim
168 words
A beverage container including, in combination, an outer container having a manually actuatable drain valve, a lid secured to and over said outer container, said lid including a gaseous pressure-relief valve, wherein said lid includes mutually spaced outer and inner walls, said inner wall being provided with airpassageway means, said relief valve being cooperatively disposed with respect to said outer wall, and wherein said outer and inner walls of said lid include aligned apertures, said pressure-relief valve comprising a valve disc centrally disposed over said aligned apertures and itself having a central aperture, said outer wall including at least one additional aperture disposed under said valve disc, elongate means disposed through said aligned apertures of said lid and said central aperture of said disc and having upper and lower reaction means, said lower reaction means coacting against said inner wall of said lid, and compression spring means disposed coaxially about said elongate means and operatively positioned between said upper reaction means and said outer wall of said lid.
Claim 3
Dependent Claim
148 words
A beverage container unit including, in combination, an outer container having a bottom and a fluid outlet valve, means for enclosing and enabling the filling of said outer container coupled thereto, said container unit including an upper gaseous pressure-relief valve, said outer container having a smooth downwardly conically tapered interior wall, a dry-ice receivable inner container having radially an upper annular lip and inwardly directed finger-pull means, said inner container also being tapered downwardly and having a transverse dimension equivalent to the interior dimension at said upper annular lip of said outer container at a medial area a distance, above said bottom, which is greater than the height of said inner container whereby, when said inner container is inserted within said outer container, said upper annular lip of said inner container wedges within said outer container to maintain said inner container in position above said outer container bottom.
