## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to containers for holding materials for storage, more specifically, to a transparent cooler for storing perishable foods.
For many years coolers have been regularly used for all types of working and recreational occasions. Whether the cooler is being used to keep items cold or warm, we use coolers when we're working and when we're playing. They go with us to construction sites and sporting events. We toss them into pickup trucks and fishing boats.
Unfortunately, due to recent international events including threat of terrorism and other acts of violence, security measures have been tightened at many public events and venues. Safety and security for guests, employees, entertainers and players have always been a concern, but these recent events have prompted security measures that include exclusion or limitation of many items including the use of coolers from such venues. Many security measures include limiting the package size and type.
Commonly such venues have continued to accept transparent packages and coolers due to the ease and ability to inspect the contents in an expeditious way.
The present invention's transparent cooler meets the demands of the new security measures and provides the user improved means to maintain and store perishable foods. The construction of the present invention's cooler includes side panels and a top cover that are made of a transparent material that allows the user or others to view the contents within the cooler.
In addition to being transparent, the cooler can be disassembled into individual components. The side and end panels are detachable from the base to allow the user improved means to clean the cooler and to reduce the size while the cooler is not in use.
The sides of the cooler are comprised of interlocking tracks and channels. Each side panel has a T-track extending from one edge with a channel on the opposing end interior face whereby each edge T-track is inserted into the channel of the adjacent side panel. Once all side wall T-tracks and channels are mated the assembled side wall structure having a further channel located within the bottom edge is inserted onto the cooler base that has spaced apart T-tracks on opposing sides of the interior face. The mating wall seams are sealed by means of gaskets on both sides of the T-track
In an additional preferred element in the construction of the present invention's end and side walls, a spaced apart panel forming an envelope is added whereby a sun blocking insulative and/or interchangeable decorative coverings can be inserted therein. The removable sun reflective panel can be inserted in any or all of the four sides and top creating an improved insulated barrier.
Artistically, the sun reflective panel may include pictorial or decorative coverings to suit the user or to reflect the venue (favorite team, player, or like).
In an additional preferred element in the construction of the present invention's end and side walls, the material is extruded to include a plurality of air gaps between the interior and exterior walls.
Still yet another additional element of the present invention includes an alternate construction of the transparent cooler utilizing a top mounted lifting handle in lieu of end panel handles. The handle is supported by adjustable straps that wrap each side and is secured with four-way receiver. The receiver has a release button to enable user access to the cooler contents. The adjustable straps acts as both, means to secure the top cover and means to lift the cooler for transporting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following discussion describes in detail one embodiment of the invention. This discussion should not be construed, however, as limiting the invention to those particular embodiments. Practitioners skilled in the art will recognize numerous other embodiments as well. For a definition of the complete scope of the invention, the reader is directed to the appended claims.
Referring to FIG. 1, depicted is an illustrative view of the present invention, a collapsible transparent cooler (10). The transparent, multi-piece cooler of the present invention (10) provides a portable unit having means to see the contents (16) within the container (10). Each of the side panels (24) and top cover (20) are made of a transparent polymeric or like material. The transparency allows the user (12) to see the contents (16) without opening the cover (20). This is particularly useful for security (14) inspections at sporting events and other controlled activities. The present invention (10) also provides means for shielding the contents (16) of the cooler (20) from direct sunlight by positioning on the exterior surface of each of the walls (24) and cover (20) an envelope (40) comprised substantially of a spaced apart wall of negligible thickness for inserting within said space a protective element to shield the interior (18) from direct sunlight. In addition, the collapsible transparent portable cooler (10) can be disassembled for storage purposes.
Referring to FIG. 2, illustrated is an isometric view of the transparent cooler of the present invention (10). Shown is the present invention having contents (16) within the transparent cooler (10). The transparency allows the user (12) to see the contents (16) without opening the cover (20). The side panels (24) are removable allowing the cooler (10) to be disassembled for storage or for ease of cleaning. The transparent cooler (10) is comprised of a removable cover (20) that engages the side walls (28, 30) and end walls (32, 34) which slidably engage each other and the base (22) to form a cooler compartment (18) for the transport therein of food and beverage items (16) which are clearly visible from the exterior of the cooler without having to remove the cover (20). The advantage of transparency is that the coolers (10) can be visually scanned without having to stop and open the cooler (10). Since many stadium events have crowds in the tens of thousands, large opaque containers have been banned in some instances due to time and personnel limitation. The present invention (10) provides means for scanning the contents (16) in a fluid movement. Much in the same way as tickets are collected at the gate. It should also be noted that since the walls (24) and cover (20) are transparent, that even indoor events having low light, the contents would still be viewable as opposed to a cooler having a transparent top or walls providing partial transparency. Each of the side (28, 30) and end walls (32, 34), in addition to the cover (20) have a spaced apart wall forming an envelope (40) for the insertion therein of user selective decorative or protective elements that would prevent the contents (16) from being exposed to direct sunlight and can easily be removed and reinserted as the need arises.
Referring to FIG. 3, shown is a partially exploded view of the transparent cooler of the present invention (10). Shown is the present invention having multiple elements comprising the transparent cooler. The side walls (28, 30) and base (22) are connected and sealed by means of T-tracks (48) and T-channels (52) having gasket seals (68). The side panels (24) are removable allowing the cooler to be disassembled for storage or for ease of cleaning. As previously stated, the present invention is a plurality of planar transparent elements comprised of a lid (20) having a top side (58) and a bottom side (60) with a flange (62) circumferentially positioned having top surface (64) and interior surface (66) for engaging and sealing the lid (20) to the walls (24). The top surface (58) of lid (20) is a spaced apart wall (42) creating envelope recess (44) with envelope access aperture (46) whereby the user can insert element to block direct sunlight from the interior (18). Lid flange (62) engages the walls (24) snap-on cover (36). Each of the side walls (28, 30) and end walls (32, 34) are manufactured in the preferred embodiment in a similar manner to reduce costs in production but is not limited to such. This being the case, a description of one infers a description for all. As an insulative factor the walls (24) are comprised of two or more spaced apart plates forming at least one air-gap (26) acting as a thermal barrier. On the exterior side there is another spaced apart plate of negligible thickness acting as an envelope (40) creating recess (44) with access aperture (46) whereby a user can insert decorative placards that can be related to the event being attended. The placards can be easily removed through access aperture (46) providing a visually transparent cooler (10) and placed back into their respective recesses (44) to shield the interior (18) from direct sunlight. On the interior side of the walls is a T-channel (52) with a T-rail (48) located on the opposing distal end. The T-rail of one wall (24) is mated with the T-channel of an opposing wall (24) thereby forming spaced apart side walls (28, 30) and end walls (32, 34). The base of each wall (24) has a longitudinally extending T-channel (52) with the end wall T-channels forming a receiving element for the locks (38). Once the side walls (28, 30) and end walls (32,34) are assembled by engaging the T-rails (48) into mating T-channels (52), the snap-on covers (36) are placed over the wall (24) edges sealing the air-gaps (26) whereupon the wall assembly is slid across the base (22) until the base (22) T-rails (48) are encompassed by the side walls (28,30) T-channels. Once positioned, the locks (38) are extended until seated within their respective end wall (32, 34) T-channels thereby creating a structurally sound transparent cooler (10). Handles (56) can be used to aid in the portability of the cooler (10) or other appropriate support means as disclosed in other drawings. Any assembly steps herein described are for descriptive purposes as there are other methods of assembly at the user's discretion.
Referring to FIG. 4, depicted is a top exploded view of the walls (24) of the present invention (10). Shown is a bottom edge view of the spaced apart walls (24) wherein each wall forms a corner on one distal end while abutting the next adjacent wall. Once assembled the walls form a rigid structure. Also shown in dotted line are the channels on the opposing edge of the side walls (26, 30) that are mounted onto the T-track (48) of the base (22). Each of the side walls (28, 30) as illustrated in comprised of spaced apart plates (24) wherein said space forms insulation (26) between the spaced apart plates. It should also be noted that a third spaced apart plate (42) on the exterior side having negligible thickness and space can be used for housing advertisement, logos, pictures, art or any conceivable opaque material that can be used to seal the cooler (10) from the rays of the sun. The side walls (28, 30) and end walls (32, 34) are manufactured in the preferred embodiment in a similar manner to reduce costs in production but is not limited to such. As shown the walls (24) are comprised of two or more spaced apart plates forming at least one air-gap (26) acting as a thermal barrier. On the exterior side there is another spaced apart plate of negligible thickness acting as an envelope (40) creating recess (44) with access aperture (46) whereby a user can insert decorative placards that can be related to the event being attended. The placards can be easily removed through access aperture (46) providing a visually transparent cooler (10) and placed back into their respective recesses (44). On the interior side of the walls is a T-channel (52) with a T-rail (48) located on the opposing distal end having gasket (68) providing means for sealing the adjacent walls (24). The T-rail of one wall (24) is mated with the T-channel of an opposing wall (24) thereby forming spaced apart side walls (28, 30) and end walls (32, 34).
Referring to FIG. 5, illustrated is a bottom view of the base (22) of the present invention. Shown are the T-tracks (48) on opposite sides, when the four side walls (24) are assembled, and securely put together, they slide on the base (22) T-tracks (48) and are secured through holes (72) in the base (22) by means of locks (38). The side walls (28, 30) and end walls (32,34) are assembled by engaging the T-rails (48) into mating T-channels (52) with the snap-on covers (36) placed over the wall (24) edges sealing the air-gaps (26) whereupon the wall assembly is slid across the base (22) until the base (22) T-rails (48) are encompassed by the side walls (28,30) T-channels. Once positioned, the locks (38) are extended through lock aperture (72) until seated within their respective end wall (32, 34) T-channels thereby preventing side walls (28, 30) from moving along the base T-rails. Disassembly occurs by rotating the locks (38) until they disengage from their respective end wall (32, 34) T-channels whereupon side walls (28, 30) can be slidably disengaged from base (22) T-rails. The side walls (28, 30) and end walls (32, 34) can then be slidably disengaged from each other thereby providing the collapsed state of the transparent cooler (10) of the present invention.
Referring to FIG. 6 shown is a detailed view of the present invention. Shown are the T-channels (52) and T-tracks (48) having rope seals (68) for a secure assembly of the four walls (24) and base (22) members. When the four side walls (24) are assembled, and securely put together, they slide on the base (22) T-tracks (48) and are secured through holes (72) in the base (22) by means of locks (38). The side walls (28, 30) and base (22) are connected and sealed by means of T-tracks (48) having T-rail tabs (50) which conform substantially in size to T-channels (52) with T-channel recesses (54). The gasket seals (68) seals the interior from liquid seepage. The side walls (28, 30) and end walls (32, 34) are manufactured in the preferred embodiment in a similar manner to reduce costs in production but are not limited to such. The spaced apart walls (24) are comprised of two or more spaced apart plates forming at least one air-gap (26) acting as a thermal barrier. On the exterior side there is another spaced apart plate of negligible thickness acting as an envelope (40) creating recess (44) with access aperture (46) whereby a user can insert decorative placards that can be related to the event being attended. The placards can be easily removed through access aperture (46) providing a visually transparent cooler (10) and placed back into their respective recesses (44) to shield the interior (18) from direct sunlight. On the interior side of the walls is a T-channel (52) with a T-rail (48) located on the opposing distal end. The T-rail of one wall (24) is mated with the T-channel of an opposing wall (24) thereby forming spaced apart side walls (28, 30) and end walls (32, 34). The base of each wall (24) has a longitudinally extending T-channel (52) with the end wall T-channels forming a receiving element for the locks (38). Once the side walls (28, 30) and end walls (32,34) are assembled by engaging the T-rails (48) into mating T-channels (52), the snap-on covers (36) are placed over the wall (24) edges sealing the air-gaps (26) whereupon the wall assembly is moved to slidably engage the base (22) until the base (22) T-rails (48) are encompassed by the side walls (28,30) T-channels. Once positioned, the locks (38) are extended through lock apertures (72) until seated within their respective end wall (32, 34) T-channels thereby creating a structurally sound transparent cooler (10).
Referring to FIG. 7, shown is an enlarged partial view of the gasket (68) of the present invention. The gasket (68) is comprised of suitable resilient material that is positioned on the T-track (48) side of each panel (24) and continues along the bottom of the panels.
