Description

FIELD OF THE INVENTION

The present invention relates to a beverage can cooler. More particularly, the present invention relates to a portable beverage can cooler capable of holding the chilled or cold canned beverage, maintaining its temperature and protecting the canned beverage from spills, dust etc thereby rendering the drink more enjoyable.

BACKGROUND OF THE INVENTION

Canning of beverages is a widely accepted and common technology for packing the beverages. It provides various benefits that include convenience in packing of cans over bottles, cans being lightweight and easier to store, they are also accident proof. Dropping a beverage bottle leaves a person with myriads of glass shards. Further, the cost of packing in cans is lower than packing the same beverage in a bottle and cans are further advantageous in offering convenience in recycling.

The canned beverages especially soft drinks, alcoholic beverages etc. are more enjoyable when they are chilled or cold depending on the individual preferences. However, the problem of keeping the beverage chilled arises when one has to carry the canned beverage while travelling, to workplace and picnics. The prior art provides cooler assembly that cools the canned beverages. The following prior art references discuss the various methods for cooling the beverages, which are produced below.

U.S. Pat. No. 5,048,305 discloses a cooler assembly of a molded plastics composition for the storage of ice-cooled, canned beverages and the like. An ice-cooled storage vessel, suspended within a self-supporting cylindrical housing of the assembly is formed with an array of vertically disposed, hollow, panel-like spacers in the lower sump zone of the vessel. Water formed during the melting of the ice collects in the sump and the spacers support the vessel-housed cans so that the spacers prevent contact of the cans with the sump water. A drain at the base of the storage vessel facilitates periodic emptying of the sump, as required. The cooler assembly is made up of molded plastic and uses ice for cooling the beverage cans wherein ice and beverage cans are physically separated. There is a provision for removing water of melted ice.

There is provided a foam composition means disposed in said spacing between said housing and said tubular vessel means for insulating an interior chamber of said cooler from the ambient environment. Further, U.S. Pat. No. 5,433,085 describes an improved chilled beverage container which allows the user to maintain beverages and unmelted ice separate from water formed by melting ice, thus in, improving the appearance of, and ease of access to, the beverages. It also allows loading with a large number of beverages, thus reducing the number of times it must be reloaded. Since the customers do not have to reach into the water to retrieve the beverages, the health risk is also reduced.

However, the methods taught in this patent is essentially used for storage of large number of ice cooled canned beverages. Once the canned beverage is removed from the assembly for the purpose of drinking, the cooling gradually drops down and in an event after opening of the can, if the user is not able to drink it immediately, there is no provision for storing the open can and maintaining its temperature and protecting it from external factors for e.g. spills, dust etc.

U.S. Pat. No. 6,067,810 provides a chilled item server formed of lightweight durable polymer. The server is made of an outer barrel of any appropriate thermoplastic formed to hold an inner liner. Prior to placing the inner liner within the outer barrel, a foaming fixture defines the inside face of an insulating body made of insulating material between the inner liner and the outer barrel. Particulate material between the fixture and the outer barrel is processed to form a fused foam between the barrel and the fixture. The fixture can then be replaced by the inner liner. The inner liner has an inner surface suitable for the insertion of multiple freezer panels, such that freezer panels thereafter are in juxtaposition with the inner surface. The freezer panels are molded polymer panels filled with cooling agent, such as saline solution, that can be frozen in a suitable freezer.

This patent teaches insulated containers for storage, display and sale of milk in school cafeteria. The disclosed improvement over the mentioned prior art comprises not requiring any ice or electricity for cooling. The freezer panels containing saline solution and insulating material provides cooling. However, it does not teach a provision for storing, maintenance of cooling and protection of canned beverage once it is removed from the server.

U.S. Pat. No. 6,227,004 relates to a portable air conditioner/beverage container having top and bottom ends, a side wall, an air intake opening and a cool air outlet. Within the container, there is a separation wall. The container utilizes a fan to pull ambient air through container that contains cooling substance and blows the air out on user. The disclosed container is capable of functioning as an air conditioner and also as a beverage container that stores number of canned beverages. The method and the purpose of the container taught herein is different and it does not teach a provision for storing, maintenance of cooling and protection of canned beverage once it is removed from the container.

U.S. Pat. No. 6,085,543 discloses a cooling mug having an inner mug part, and an outer mug part joined together with a room in between. The room holds the cooling substance and a straw therein; the straw is connected to a lower end of the inner part, and communicates with inside of the inner part provided for holding drinks. The straw further projects from upper end of the mug so that a user can suck drinks from the straw. The mug is previously kept in a refrigerator to become cold. The included drink flows into the straw after it is poured into mug; thus, drinks sucked up from the straw become cooler because of the contact between the straw and cooling substance. The mug taught in the patent does not comprise either a lid or a cover. Further, it is not designed to accommodate canned beverages and needs to be kept in refrigerator prior to pouring of beverages. There is no provision of maintenance of cooling after the beverage is cooled and hence once cooled, the user has to drink the beverage immediately. Further, it cannot be carried from one place to another as no lid is provided.

U.S. Pat. No. 7,426,839 relates to an apparatus and method for cooling a beverage through the special design of a container for dispensing a beverage. The beverage remains cold for a period of time while it is inside the container, through contact with a frozen consumable substance with a lower temperature than the beverage. The frozen substance is substantially frozen before the beverage is introduced into the container. The beverage and the frozen substance make contact through portions of a barrier structure containing the frozen substance. As the frozen substance melts, it gradually mixes with the beverage, continuing to cool the beverage over a period of time, without ice floating to the top of the container. However, the apparatus and method disclosed herein is for cooling bulk of non packed beverage and not for cooling the canned beverages. Further the disclosed cooler is an open apparatus, does not comprise a lid to protect the beverage and is not designed to accommodate canned beverages.

US2003161931 relates to an open topped drinking vessel containing a beverage, the beverage comprising a water content and a dissolved gas content and having a head overlying an ice formation made of many ice crystals, the ice formation having been produced by ice formed in the beverage whilst the beverage is in the drinking vessel. The vessel taught herein is also used to cool the non canned beverage and cannot be used to maintain the cooling.

The prior arts discussed above relates to coolers that are used for storing and cooling the canned beverages with the help of cooling substance and also accommodate insulating material and cooling mugs that are capable of cooling the poured beverages with the help of cooling substance and insulation. However, none of the prior art discussed above provides a solution for storing the chilled canned beverage once removed from freezer or ice crest, maintaining the cooling effect and protecting it from spills and dust.

Therefore, there exists a need within the art for a portable can cooler that overcomes at least the aforesaid shortcomings of the prior art.
