Abstract
Abstract A plastic container which confines a freezable liquid is provided with a multitude of parallel channels which permit passage of air through the container. The container is mountable upon the protective enclosure of a multi-bladed air-moving fan in a manner such that air driven by the fan passes through the channels and is thereby cooled. The container is of a small enough size to permit its storage within a residential-type freezer to freeze the liquid prior to mounting of the container upon the fan. 2

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
141 words
A plastic container for a freezable liquid, said container being of monolithic construction having been fabricated of a thermoplastic polymer by a molding operation and being further characterized in having: (a) upper and lower extremities, (b) opposed parallel front and rear surfaces, (c) a high ratio of total surface area to confined volume, (d) a multitude of parallel channels that extend between said front and rear surfaces, (e) a plane of symmetry that bisects said upper and lower extremities, (f) attaching means for removably associating said container with an air circulation device, said attaching means being apertured tabs associated with said upper and lower extremities and centered upon said plane of symmetry. (g) a closable opening permitting entrance and egress of said liquid, and (h) a configuration amenable to the stacking of a number of said containers in a compact grouping
Claim 2
Dependent Claim
141 words
A plastic container for a freezable liquid, said container being of monolithic construction having been fabricated of a thermoplastic polymer by a molding operation and being further characterized in having: (a) upper and lower extremities, (b) opposed parallel front and rear surfaces, (c) a high ratio of total surface area to confined volume, (d) a multitude of parallel channels that extend between said front and rear surfaces, (e) a plane of symmetry that bisects said upper and lower extremities, (f) attaching means for removably associating said container with an air circulation device, said attaching means being apertured tabs associated with said upper and lower extremities and centered upon said plane of symmetry. (g) a closable opening permitting entrance and egress of said liquid, and (h) a configuration amenable to the stacking of a number of said containers in a compact grouping
Claim 3
Dependent Claim
20 words
The container of claim 1 wherein said polymer is chosen so as to produce a somewhat resilient, non-breaking molded container.
Claim 4
Dependent Claim
18 words
The container of claim 2 defined by wall structure having a uniform thickness between 0.5 and 1.5 millimeters.
Claim 5
Dependent Claim
20 words
The container of claim 2 wherein the ratio of surface area to volume is between about 1 and 20 cm-1.
Claim 6
Dependent Claim
28 words
The container of claim 2 wherein said channels have curved shoulders adjacent said front and rear surfaces for the purpose of streamlining passage of air through the channels.
Claim 7
Dependent Claim
41 words
An air cooling and directing apparatus comprising a multi-bladed oscillating fan having a circular protective enclosure, bracket means extending horizontally from said enclosure, and a container of claim 2 supported by the interengagement of said bracket means with said attaching means.
