Abstract
Abstract A tubular expandable elastic container for holding and dispensing a frozen confection as it thaws. The frozen confection holds the container in an expanded configuration, and as it thaws the contraction of the container forces thawed frozen confection from an open end of the container. A whistle is also provided at the open end of the container and a valve in the whistle structure for preventing air from entering the container when a user blows air into the whistle.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
149 words
A progressive fluid dispensing system for continuously feeding thawing frozen confection, comprising: a resilient container having an open end and a closed end; said resilient container having a first, expanded configuration in which said frozen confection maintains the resilient container in the expanded configuration, and a second configuration in which the resilient container progressively contracts as the frozen confection thaws, whereby, thawing frozen confection flows from said open end of the container at a rate proportional to the rate of thawing of said frozen confection within said resilient container; a hollow member attached to and disposed within the open end of said resilient container and having means for whistling when a user blows air into an opening in said hollow member, and valve means at the inner end of said hollow member for preventing air from entering into said resilient container when a user blows into said hollow member.
Claim 2
Dependent Claim
149 words
A progressive fluid dispensing system for continuously feeding thawing frozen confection, comprising: a resilient container having an open end and a closed end; said resilient container having a first, expanded configuration in which said frozen confection maintains the resilient container in the expanded configuration, and a second configuration in which the resilient container progressively contracts as the frozen confection thaws, whereby, thawing frozen confection flows from said open end of the container at a rate proportional to the rate of thawing of said frozen confection within said resilient container; a hollow member attached to and disposed within the open end of said resilient container and having means for whistling when a user blows air into an opening in said hollow member, and valve means at the inner end of said hollow member for preventing air from entering into said resilient container when a user blows into said hollow member.
Claim 3
Dependent Claim
50 words
A progressive fluid dispensing system as recited in claim 1, wherein said resilient container is formed of a resilient thermoplastic material, said hollow member is detachable from said open end of said resilient container, and an aperture in said hollow member for permitting the passage of said thawing frozen confection.
Claim 4
Dependent Claim
24 words
A progressive fluid dispensing system as recited in claim 1, wherein said resilient container has a flattened configuration in cross-section when it is empty.
Claim 5
Dependent Claim
31 words
A progressive fluid dispensing system as recited in claim 1, wherein said resilient container in said first configuration is a substantially straight configuration and said second configuration is a coiled configuration.
Claim 6
Dependent Claim
35 words
A progressive fluid dispensing system as recited in claim 1, wherein said resilient container in said second configuration is a zigzag configuration and said first configuration is a substantially straighter configuration than said zigzag configuration.
Claim 7
Dependent Claim
24 words
A progressive fluid dispensing system as recited in claim 1, wherein said means for whistling includes a series of openings in said hollow member.
