Description




FIELD OF THE INVENTION




The present application relates to coolers.




BACKGROUND INFORMATION




Conventional coolers typically comprise one cooling compartment for holding perishable items in thermal isolation from surrounding conditions. Beverages are usually stored in their own containers along with other items in the cooling compartment. To dispense a beverage, a user typically opens the cooler lid, removes a beverage container and pours the contents of the container. If the beverage container is reusable, the user may replace the container in the cooling compartment. To do so, the user will either keep the cooler lid open throughout the dispensing process, or close and reopen the lid to replace the beverage container. Putting the reusable container beverage container back into the cooling compartment may be difficult and time consuming if other items in the compartment have shifted into the cavity created by the removal of the beverage container. While the lid is open, the contents of the cooling compartment are exposed to the ambient conditions, thereby compromising the thermal isolation function of the cooler.




A cooler marketed by the Igloo Products Corporation of Tulsa, Okla. provides for a beverage dispenser which dispenses a beverage by gravity through a spout which protrudes through an opening near the bottom of the cooler. The low position of the spout, necessitated by the reliance on gravity, makes such an arrangement inconvenient to use and susceptible to dirt contamination. The constant exposure of the spout to the exterior of the cooler further increases the possibility of contamination. Furthermore, the opening in the cooler through which the spout passes may leak water created from ice melting in the cooler compartment if the user has not properly installed the beverage dispenser. Moreover, the beverage dispenser cannot be used outside of the cooler without completely emptying the cooler and installing a separate plug to seal the opening provided in the cooler for the dispenser spout.




SUMMARY OF THE INVENTION




The present invention provides a cooler which is adapted for receiving therein a specially adapted beverage dispenser. The dispenser can be operated to dispense a beverage while the dispenser is seated within the cooler. When not in use, the dispenser can be enclosed entirely within the cooler to retain its contents in thermal isolation from the ambient conditions. The beverage dispenser can also readily be removed from the cooler and used independently of the cooler to contain and dispense beverages.




A first exemplary embodiment of a cooler in accordance with the present invention comprises one cooling compartment which is adapted to receive a beverage dispenser and to store other items in thermal isolation from the exterior. In this embodiment, the cooling compartment is accessed via one lid.




A further exemplary embodiment of a cooler in accordance with the present invention comprises two cooling compartments: one compartment for receiving a beverage dispenser and a main compartment for retaining other items. The compartment containing the beverage dispenser can thus be accessed without opening the main compartment and thereby exposing the main compartment to the ambient conditions.




Unlike known coolers, beverages can be dispensed from the beverage container without removing the container from the cooler. This avoids the problem of trying to replace the container into the cooler only to find that other items have shifted into the space previously occupied by the beverage container. As a result, the process of dispensing a drink is accelerated, reducing the amount of time that the cooler lid stays open and thus allowing the cooling compartment to stay cooler longer.




A cooler in accordance with the present invention may also preferably comprise wheels and a pull handle to facilitate transportation of the cooler. An improved cooler liner and cooler lid are also disclosed.

DETAILED DESCRIPTION





FIG. 1A

shows a perspective view of an exemplary cooler


100


in accordance with the present invention.

FIG. 1B

shows the exemplary cooler


100


in a perspective exploded view. As shown, the cooler


100


comprises a lid


110


and a cooler body


120


, with the lid


110


being pivotally attached to the body


120


such as by one or more hinges


115


, or other suitable joining means. The lid


110


may alternatively be detached from the cooler body


120


. The cooler


100


is generally in the shape of a rectangular solid with the cooler body


120


having a generally rectangular opening and the lid


110


having a corresponding generally rectangular shape. Of course, other shapes are possible within the scope of the present invention.




The cooler


100


comprises an interior compartment


150


for storing items to be thermally insulated from the exterior. The compartment


150


is adapted to receive therein a beverage dispenser


300


, which will be described more fully below.




The cooler


100


may optionally comprise wheels


125


arranged proximate to a bottom edge of the cooler body


120


. When the cooler


100


lies flat on a flat surface, the wheels


125


preferably do not touch the flat surface (See FIGS.


8


A-


8


C). The wheels


125


engage the surface when the cooler


100


is lifted from the end of the cooler opposite the wheels. This provides for a more stable configuration and prevents the cooler from unintentionally pivoting about the wheels should, for instance, a person sit on the cooler at the wheeled end of the cooler. To facilitate pulling the cooler


100


, the cooler may also include a pull handle


127


arranged on a wall of the cooler opposite of the wheels


125


. The pull handle


127


is preferably hinged on the cooler so as to swing down and out of the way when not in use. The cooler


100


may also preferably comprise lifting handles


128


and


129


arranged on opposite ends of the cooler body


120


, as shown in FIG.


1


B. The lifting handles


128


,


129


can be implemented in a variety of known ways.




As shown in

FIG. 1B

, the cooler body


120


comprises a shell


130


, which forms the exterior of the cooler body, and a liner


155


which is inserted into the shell


130


. As with conventional cooler designs, the shape of the liner


155


generally conforms to the shape of the interior of the shell


130


while allowing a space between the liner


155


and the shell


130


for the introduction therein of an insulating material (not shown). The interior compartment


150


is delimited by the liner


155


and the lid


110


.




The liner


155


is adapted for receiving the dispenser


300


therein. In the exemplary embodiment shown, the liner


155


generally has the shape of an open box, with a bottom surface and two pairs of opposing walls. The liner


155


is shown in greater detail in

FIGS. 7A through 7F

, described more fully below.




The dispenser


300


is adapted to fit entirely within the compartment


150


between two opposing walls


156


and


158


of the liner


155


. The walls


156


and


158


have formed therein coupling features


157


and


159


, respectively. The coupling features


157


,


159


can be formed into the liner walls as slots, as shown in FIG.


1


B. (See also

FIG. 7A.

) When the dispenser


300


is placed in the compartment


150


, the coupling features


157


and


159


receive complementary coupling features


357


and


359


, respectively, formed on the dispenser


300


. In the embodiment shown, the complementary coupling features


357


,


359


are formed as projections which slide within the slots


157


,


159


formed in the liner


155


. The engagement of the slots


157


,


159


with the projections


357


,


359


secure the dispenser


300


within the compartment


150


, preventing lateral movement of the dispenser within the compartment while allowing the dispenser to be pulled upwards, out of the compartment.




As shown in

FIGS. 1A and 1B

, the dispenser


300


is preferably placed at an end of the compartment


150


proximate to the wheels


125


. Such an arrangement is conducive to pulling the cooler


100


when the dispenser


300


is full and thus fairly heavy.




As shown in

FIG. 1B

, the dispenser


300


comprises a container


310


and a pump assembly


320


. In the exemplary embodiment shown, the container


310


comprises a threaded opening


315


for receiving the pump assembly


320


. The pump assembly


320


comprises a complementary threaded coupling for engaging the threaded opening of the container. Naturally, other suitable, well-known arrangements for removably coupling the pump assembly


320


to the container


310


can also be used. Preferably, the opening


315


is large enough (e.g., 4″ in diameter) to allow cleaning the interior of the container


310


by hand.




To fill the dispenser


300


, a user unscrews the pump assembly


320


from the container


310


, thereby exposing the opening


315


, and pours a liquid, such as a beverage, into the container


310


. Once full, the pump assembly


320


can be reinserted and screwed onto the container


310


. The liquid in the container


310


can then be dispensed by operating the pump of the pump assembly


320


.





FIGS. 3A through 3B

and


4


A through


4


C illustrate the operation of the dispenser


300


. The pump assembly


320


comprises a pump


330


which comprises a plunger


332


with a spout


335


attached thereto. The pump


330


operates in a conventional manner to dispense the liquid contents of the dispenser


300


via the spout


335


by raising and depressing the plunger


332


. When the plunger


332


is raised, the pump


330


draws liquid from the container


310


. When the plunger


332


is depressed, the liquid drawn by the pump


330


is expelled from the spout


335


. Preferably, as shown in

FIGS. 3 and 4

, the plunger


332


can swivel about its axis between at least a first and second position. In the first position, shown in

FIG. 3C

, the lid


110


can be closed over the beverage dispenser


300


. In the second position, shown in

FIGS. 3A and 3B

, the spout


335


can dispense liquid over a side of the cooler


100


when the dispenser is in the cooler, as shown in FIG.


1


A. Of course, the pump can also be operated with the dispenser


300


removed from the cooler


100


.




The amount of liquid dispensed by depressing the plunger


332


once is a function of how high the plunger is pulled up, and thus of how much liquid is drawn by the pump


330


in the upward stroke. In a further exemplary embodiment, the plunger


332


may include graduated markings which indicate the volume of liquid to be dispensed when the plunger


332


is depressed from a particular level. In an exemplary embodiment, the pump


330


will dispense


4


fluid ounces of liquid for one full stroke of the plunger


332


.





FIG. 5

shows a perspective view of the container


310


, while

FIGS. 6A

,

E show top, front, bottom, side and rear views, respectively, of the container. As shown in

FIG. 5

, the container


310


preferably comprises a handle


317


for lifting and carrying the dispenser


300


. The dispenser


300


can also be carried with two hands using finger handle reliefs


318


formed on opposite ends of the container


310


. The container


310


may include graduated markings on one or more side to indicate the level of liquid therein.





FIG. 2A

shows a perspective view of a further exemplary embodiment of a cooler

210


B and a cooler body


220


, with the lids


210


A and


210


B being pivotally attached to the body


220


such as by hinges, or other suitable joining means.




In this embodiment, the cooler


200


comprises two interior compartments


250


A and


250


B. Compartment


250


A is used for storing items to be thermally insulated from the exterior. Compartment


250


B is used for receiving a beverage dispenser in accordance with the present invention, such as the beverage dispenser


300


described above. Each of the compartments


250


A and


250


B has a corresponding lid


210


A and


210


B, respectively, thereby allowing the compartments


250


A and


250


B to be accessed independently via the lids


210


A and


210


B, respectively. Thus, for example, the dispenser


300


can be accessed to dispense a beverage while keeping the compartment


250


A closed and thus thermally isolated from the exterior of the cooler


200


.




As with the embodiment of

FIGS. 1A and 1B

, the cooler


200


comprises a cooler body


220


. The body


220


comprises an exterior shell


230


and a liner


255


arranged in the shell. In this embodiment, the liner


255


is formed with a partition


277


which separates the interior compartments


250


A and


250


B. The partition


277


may include one or more posts


279


which may be necessitated by a molding process used to form the liner. The posts


279


also impart rigidity to the partition


277


and may also provide a keying function in placing the dispenser


300


in the compartment


250


B. As shown in

FIGS. 6B and 6C

, the container


310


of the dispenser


300


may be provided with indentations


379


which complement the posts


279


on the partition


277


. The posts


279


and indentations


379


thus allow the dispenser to be placed in the compartment


250


B with only one orientation.




In all other material respects, the construction of the cooler


200


is substantially similar to that of the cooler


100


, described above.




A cooler in accordance with the present invention can be manufactured using well-known techniques and materials such as plastics.





FIG. 7A

shows a perspective view of the liner


155


as used in the exemplary single-compartment cooler


100


described above.

FIG. 7B

is a side view of the liner


155


and

FIG. 7C

is a cross-sectional view. As shown, the liner


155


comprises an integral lip


165


which surrounds the perimeter of the liner opening. The lip


165


provides rigidity to the liner and provides a surface for mating the liner to the shell


130


of the cooler body.

FIG. 7D

shows a detailed perspective view of a portion of the lip


165


.




As shown in cross section in

FIGS. 7E and 7F

comprises a horizontal surface


165




a


and a vertical surface


165




b


which are substantially mutually perpendicular. The horizontal surface


165




a


is substantially perpendicular to the side walls


155




w


of the liner. In accordance with the present invention, the lip


165


is provided with stiffening features


175


arranged along the two edges defined by the surfaces


165




a


,


165




b


and


155




w


. As shown, the stiffening features


175


can be formed as indentations arranged at an angle (e.g., 45 degrees) to the adjoining surfaces. The stiffening features


175


serve to maintain the intended angular relationship between the surfaces adjoining the edges into which the features are formed. The stiffening features


175


are molded into the edges integrally with the lip


165


. The features


175


allow the use of softer, more flexible and thus less expensive plastic which may otherwise tend to lose its shape after being molded. Although shown with respect to the one-compartment liner


155


, the stiffening features


175


can also be used with the two-compartment liner


255


or conventional liners.





FIGS. 8A through 8C

and


9


A through


9


D illustrate an exemplary embodiment of a hinge for attaching the lid


210

comprises a ridge


211


adjacent to the hinge line which abuts the hinge projections


217


on the cooler body when the lid is fully opened, as shown in

FIGS. 9C and 9D

. The abutment of the ridge


211


against the projections


217


prevents the lid from opening further. As shown in

FIG. 9C

, in the fully open position, the angle defined by the top of the cooler body


220


and the lid


210


is preferably greater than


90


degrees so that the lid will stay open by itself in the fully opened position.




Although shown with respect to the split-compartment embodiment of

FIGS. 2A and 2B

, such a hinge may be used in a wide variety of coolers and other similar devices.




The lids


110


and


210


of the exemplary coolers described above may also include attachment features


117


, as shown in

FIGS. 10A through 10E

. The attachment features may be used for attaching bungee cords, for example, to the lid. The provision of bungee cords on the lid makes it possible to temporarily secure items to the top of the cooler. One or more attachment points


117


are preferably arranged along opposing edges of the lid


110


. As shown, two attachment points


117


are arranged on the far ends of the lid. The attachment points


117


may be formed as openings, as shown in the cross-sectional view of

bungee cord can be passed through the opening and held in place such as by being knotted at one end. As shown, the attachment features


117


are preferably integrated into the edge of the lid.




As shown in

FIG. 10A

, in an exemplary embodiment, the lid


110


(or


210


) comprises one or more cup holders


116


. In the exemplary embodiment, the cup holders


116


have a depth of approximately 2″. The depth of the holders will depend on the thickness of the lid. Moreover, a clearance between the bottom surface of the lid and the bottom of each cup holder should be maintained so as to allow for insulation, such as urethane foam, in the lid to completely surround the cup holder for cold retention properties. The distances of the cup holders from the cooler lid perimeter, the distances of the cup holders from each other and the clearance between the bottom surface of the lid and the cup holder protrusions into the lid cavity are selected so as to provide an achievable blow molding draw ratio depth. In accordance with the present invention, the cup holders


116


can be formed in the lid even though the lid is manufactured using blow molding techniques.




Also, as shown in

FIGS. 10B and 10D

, the underside of the lid


110


is advantageously provided with indented areas


118


for maximizing the useful interior volume of the compartment


150


when the lid is closed. Further indentations


119


within the indented areas


118


can be provided for accommodating tall items such as bottles. To assist in placing such items beneath the indentations


119


, locator marks, such as dimples or mounds or other suitable markings, can be formed in or placed on the liner


155


directly beneath the indentations


119


.
