This non-provisional is entitled to the benefit of, and claims priority to Provisional Patent Application Ser. No. 63/460,765, entitled “Vertical Beverage Can Cooler,” filed on Apr. 21, 2023, which is included by reference as fully set forth herein.
TECHNICAL FIELDThe present invention relates generally to the field of household appliances, and more specifically without limitation, to an apparatus for storing, cooling, and releasing canned beverages.
BACKGROUND OF THE INVENTIONSolutions for cooling and maintaining temperature of food and drink have a long history. In particular, there has long been significant consumer demand for devices and methods to chill canned beverages, preferably in a portable, easy-to-use manner, in order to keep drinks at optimal temperatures in a variety of settings. Desirable characteristics of such cooling solutions include speed of cooling, duration of temperature maintenance, durability, portability, and volume. However, there are inherent trade-offs between these characteristics, creating a complex design puzzle.
Insulation is perhaps the most common solution for maintaining the temperature of canned beverages over time. Insulated coolers typically rely on pre-chilled contents and additional ice packs or ice to create a cold storage environment. While effective for gradual temperature maintenance over several hours to days, they do not actively cool beverages. Ice-packed coolers also require significant preparation. Moreover, the shells of insulated coolers are often thick, greatly increasing the overall bulk of the cooler, particularly with respect to coolers which feature a high ratio of surface area relative to the volume of their internal cavity.
Alternatively, coolers may actively lower interior temperature. The most common technology involves vapor-compression refrigeration, which requires a liquid refrigerant and mechanical cooling elements such as a compressor and condenser. Alternatively, thermoelectric cooling (TEC) may be used to transfer heat using the Peltier effect. Both technologies have trade-offs and present design challenges with respect to achieving desired cooler characteristics such as portability and durability.
Coolers are typically configured in a rectangular or box-like shape, maximizing internal storage volume relative to the overall footprint. This design facilitates easy stacking and storage of canned beverages, alongside ice packs or ice, to maintain a cold environment for extended periods. In some circumstances, the rectangular shape may also be conducive to packing and transportation, such as in car trunks.
These traditional box-shaped coolers, however, are poorly suited for many settings. For example, in order to provide golfers with a means of easily accessing cool canned beverages throughout a round of golf, a cooler designed to fit within the tall, narrow confines of a golf bag would be desirable. Likewise, there are numerous portability use cases in which space may be extremely limited in one or more dimensions, rendering the rectangular configurations of existing coolers impractical.
Furthermore, most conventional coolers are configured such that users open a lid to access the inner cavity and select from the contents. This process results in inefficiencies, as the entire contents of the cooler are exposed each time the interior is accessed. It would also be incompatible with a tall, narrow cooler in which the lower reaches of the inner cavity may be inaccessible.
In light of the shortcomings in the prior art, there is a need for an apparatus and/or method for storing, cooling, and accessing items, such as canned beverages, that minimizes storage footprint with respect to the cooler's width and/or depth, while providing a means to easily and efficiently access said beverages.
SUMMARY OF THE INVENTIONThe present invention is directed to an apparatus used for cooling, storing, and accessing items contained therein, particularly canned beverages.
Such an apparatus may comprise a hollow tube, one or more thermoelectric cooling elements, and an air channel. The one or more thermoelectric cooling elements substantially contact the tube, thereby reducing the temperature of the tube's inner cavity and contents thereof, and may be powered by a power source coupled to the apparatus. The air channel may be arranged parallel to the apparatus tube and disposed within an air channel housing comprising inlet and outlet vents and, preferably, a fan or other means to direct airflow.
An apparatus according to the present invention, configured as described above, allows for novel dimensions relative to prior-art coolers. For example, the tube may feature a cylindrical inner cavity having the minimal diameter necessary to accommodate a single standard canned beverage and having a height sufficient to accommodate a plurality of canned beverages, stacked serially in a vertical arrangement. This provides for a cooler with an advantageously small footprint relative to its internal capacity, a feature that is desirable for a number of applications, including incorporation into a golf bag.
In various embodiments, the apparatus further comprises a head covering one end of the tube, which controls access to the contents of the inner cavity. This head may comprise a retainer assembly and release mechanism, wherein the head retains items within the tube's inner cavity until the release mechanism is activated, whereupon at least one item is released. A force mechanism within the tube may be used to drive the contents of the inner cavity upwards, such that, when a first item is released, it is replaced by a second item, which thereupon engages with the retainer assembly in preparation for release. These features allow items stored in the inner cavity to be serially accessed, even when the narrow dimensions of the inner cavity do not permit access to its lower depths.
The present invention also provides a method for using such an apparatus, having some or all of the elements described above, in order to store, cool, and release items such as canned beverages. According to this method, a plurality of items are stacked serially within a tube in a vertical arrangement. The items are then cooled by means of one or more thermoelectric cooling elements contacting the exterior surface of the tube. A release mechanism coupled to the tube is then activated, causing a first item to be released. A second item is then driven towards the top end of the tube by means of a force mechanism.
The following detailed description is of the best currently contemplated modes of carrying out various embodiments of the invention. The description is not to be taken in a limiting sense, but is made for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
Referring still to the embodiment of
The air channel housing 15, as configured in the embodiment of
In various embodiments, the cooler housing 13 may include additional surface features designed to interface with cooler accessories or with external elements. For example, the air channel housing 15 shown in
In the embodiment depicted in
As depicted in the embodiment of
In various embodiments, the cooler will further comprise a fan 25 or other equivalent means to drive airflow. For example, as shown in
In some embodiments, the cooler's air channel 24 may be divided into an upper hot air space 26 and lower cool air space 27, divided by an air channel shelf 28 built into the air channel housing 15. The air channel shelf 28 may feature one or more openings 29, allowing cool air from the cool air space 27 to recirculate into the hot air space 26, reducing the air channel's overall ambient temperature.
In various embodiments, the one or more cooling elements 21 are solid-state thermoelectric cooling (TEC) devices, which transfer heat using the Peltier effect. Referring to
It should be understood that, in various embodiments, cooling elements 21 and/or power source 22 may be further connected to a controller or similar electronic elements, which elements control and coordinate operation of the electronic components of the apparatus. Likewise, all of the foregoing electronic components may be connected to a user interface, allowing a user to adjust the temperature and otherwise control the functioning of the apparatus. Such features are well known in the prior art with respect to generic electronics systems and not described in detail herein.
Incorporation of solid-state thermoelectric cooling elements has a number of important advantages in the context of the present invention. Because TEC systems have no moving parts, a cooler configured according to the embodiment described above is much more durable and portable relative to using alternative means of temperature control. Likewise, TEC systems do not require refrigerant, making the apparatus safer and more durable. Further, TEC elements are available in relatively small sizes and versatile shapes, thereby facilitating a cooler with desired dimensions as disclosed herein. In particular, a cooler according to the present invention may preferably utilize thin, wafer-shaped thermoelectric cooling pads in order to minimize the footprint of the apparatus.
TEC systems have nevertheless traditionally involved trade-offs, including limitations with respect to the efficiency and maximum capacity of heat transfer. However, the present invention addresses many of these design challenges. In particular, the air channel shelf 28 and opening 29 described above are designed to reduce the ambient temperature of the air channel. Limited cold air is introduced into the air stream flowing across the heat sink(s), while hot air is continuously expelled through the air outlet vent. Using thermoelectric cooling elements 21 configured as described above, it is possible to efficiently maintain an inner cavity 70 temperature of approximately 38 degrees Fahrenheit below ambient.
As illustrated in
In various embodiments, a cooler apparatus according to the present invention further comprises a head assembly 40 coupled to the top 10 of the cooler. Referring to
An important secondary object of the present invention is to provide a means of serially releasing items from the cooler's inner cavity. To accomplish this, the head assembly preferably comprises a release mechanism 42 and retainer assembly 43 (see
In the embodiment depicted in
Referring to
Referring still to
The release mechanism 42 and retainer assembly 43 may be used in combination with a force mechanism 90 that exerts upward force on items stored within the cooler. In the embodiment depicted in
By way of example, a cooler having the release mechanism, retainer assembly, and force mechanism described above may operate as follows. A user first loads a plurality of canned beverages 94, 95, 96 such as a standard six pack, into the tube 20, thereby depressing the cavity spring 93, as illustrated in
It should be understood that the release mechanism and related elements described above are merely one way to accomplish the serial release of items stored in a cooler according to the present invention. Alternative solutions may be preferable depending on commercial factors such as manufacturing cost, consumer price sensitivity, and intended applications for the device.
A further advantage of the present invention is its modularity. As discussed above, a key feature of the cooler apparatus disclosed herein is that it may be configured in an unconventional vertical shape. The utility of such a cooler may be enhanced by various external accessories, allowing users to customize the device according to their particular needs. In certain embodiments, these accessories may be detachable and/or exchangeable and may be distributed separately from the base device.
One such accessory is designed to incorporate the cooler into a golf bag.
Referring still to
The golf bag internal assembly 50 described above may be integrated with a wide variety of elements typical of conventionally manufactured golf bags, which are well known in the prior art and therefore not described in detail herein. For example, a support framework 58, comprised of one or more rigid or semi-rigid vertical support structures, may be disposed between the top frame 51 and base 52, all of which is surrounded by a covering of canvas, leather, or other material, the bottom of which is fastened to the perimeter of the golf bag base 52 and the top of which is fastened to the perimeter of the golf bag top frame 51, thereby enveloping the contents of the golf bag while leaving the openings 53, 55 in the top frame 51 accessible.
Various mount accessories may be used to fix the apparatus to particular surfaces, objects, or locations. For example,
Another external accessory is directed to a detachable handle with pivotable stand legs, designed to permit the cooler to stand freely in a tripod stance.
External joiner accessories may also be used to couple multiple coolers, essentially creating a system with expanded storage capacity. For example,
