ICE Core, Beverage Container with ICE Core and Method of Making

This application claims priority to U.S. Provisional Application No. 63/567,509, filed on Mar. 20, 2024, U.S. Provisional Application No. 63/639,771, filed on Apr. 29, 2024, and U.S. Non-Provisional application Ser. No. 18/912,698, filed Oct. 11, 2024, the entire disclosures of which are incorporated herein by reference.

Embodiments of this disclosure relate generally to modifying or maintaining the temperature of beverages, for example cooling or warming beverages. In one example, an insert may be used with a beverage container for cooling or warming a liquid in the container with enhanced conduction and convection without dilution of the liquid.

The addition ice directly to a beverage for the purpose of cooling the beverage is well known. Ice can be produced to have a variety of geometries, shapes, and/or textures. Regardless of whether when the ice is added to a beverage, container prior to filling the container with a liquid or after the container has been filled with ice, the effect is the same. That is, because the temperature of the liquid is typically less than the temperature of the ice, the higher temperature of the liquid will be absorbed by the ice. Melting of the ice will occur promptly due to the process of heat transfer and melting that occurs between the ice and the liquid. If the ice and liquid are stirred or agitated, then the heat transfer and melting process will be more pronounced. A result of the heat transfer and melting that occurs between the ice and the liquid in the container is that the liquid will become diluted with the content of the ice. For example, water in the ice will dilute the liquid in the beverage container to have a taste that is sufficiently different than the taste of the liquid that is present in its originally served form. Not only is dilution an issue with the use of ice, but the length of time that the liquid in the beverage container will be chilled is diminished at a faster rate than is ideally desired due to the heat transfer and melting that occurs between the ice and the liquid.

The following presents a simplified summary of the disclosed subject matter in order to provide a basic understanding of some aspects of the various embodiments described herein. This summary is not an extensive overview of the various embodiments. It is not intended to exclusively identify key features or essential features of the claimed subject matter set forth in the Claims, nor is it intended as an aid in determining the scope of the claimed subject matter. Its sole purpose is to present some concepts of the disclosure in a streamlined form as a prelude to the more detailed description that is presented later.

In light of the issues associated with using ice to chill liquid in a beverage container such as dilution of the liquid and a diminished time that the ice is able to chill the liquid, a need exists for an alternative approach that can overcome these issues. The various embodiments of the present invention described herein overcome these issues by providing an ice core for use with a beverage container. The ice core of the various embodiments is configured so that there will be zero dilution of the liquid in the beverage container, all while providing both enhanced conduction and convection effects that keep the liquid chilled for a longer period of time in comparison to the conventional approach that relies solely on ice to chill a liquid in a beverage container. In addition, the ice core can be configured to be disposable after its usage with the beverage container.

Example embodiments of the present invention will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments are shown. Indeed, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. For like numbers may refer to like elements throughout.

Certain embodiments commensurate in scope with the originally claimed subject matter are summarized below. These embodiments are not intended to limit the scope of the claimed subject matter, but rather these embodiments are intended only to provide a brief summary of the possible embodiments. Indeed, the disclosure may encompass a variety of forms that may be similar to or different from the embodiments set forth below.

The present embodiments may solve a problem for regulating a temperature of a beverage without modifying or diluting the beverage. Specifically, the present invention may allow multiple dimensional cooling or heating of the entire beverage by inserting a thermal regulating core including a thermal regulating material such that the beverage can be cooled or heated synchronously using the conduction and convection effects of the invention. Because the thermal regulating core and thermal regulating material are isolated from the beverage, the taste of the beverage may be unimpacted by the cooling or heating of the system and may remain constant.

Further, by more efficiently regulating the temperature of beverages, less ice may be used, and time may be saved as a result of not having to add ice to each and every beverage to create a cool or cold beverage. Additionally, the flavor of the beverage is not impacted or diluted by the melted ice.

Turning now to the figures,shows a schematic of an core, for example an ice core, for use with a beverage container according to an embodiment of the invention. While discussed with respect to being an ice core for cooling a beverage, the coremay be a warming core for warming and/or maintaining the temperature of a beverage. As shown in, the ice coreincludes an ice core bodyhaving a cylindrical shape with a first endand an opposing second end. In one embodiment, the first endof the ice core bodycan have a diameter (D) larger than the diameter of the second endof the ice core body. In one embodiment, as shown in, the diameter of the ice core bodycan decrease progressively from the first endto the second end.

The ice corecan also include an ice core rimformed on the first endof the ice core body. In one embodiment, the ice core rimcan have a bottom surfaceon the first endof the ice core body, a top surface, and a pair of opposing side surfacesconnecting the bottom surface with the top surface. As shown in, the bottom surfaceof the ice core rimcan have a length corresponding with the diameter of the first endof the ice core bodyand the top surfaceof the ice core rimcan have a length extending beyond a periphery of the diameter of the first endof the ice core body. In one embodiment, each of the opposing side surfacescan project inwardly from the top surfaceof the ice core rimto the bottom surfaceof the ice core rimto form a rolled outward rimthat extends beyond side periphery of the ice core body.

The ice corecan further include an ice core tubeformed through the ice core bodyand the ice core rim. In one embodiment, the ice core tubecan form an openingthrough the ice core bodyand the ice core rim. The opening can extend from the top surfaceof the ice core rimto the bottom surfaceof the ice core rimand through the first endto an openingin the second endof the ice core body. In one embodiment, the ice core tubecan take the form of a hollow, circular tube having a predetermined diameter that descends through the ice core body in a substantially, straight, downward direction.

In other examples, the ice core tubemay be of a different shape, for example having a cross-sectional shape of a square, a rectangle, a pentagon, a hexagon, another polygon, or an irregular shape. The shape may be selected to increase surface area, thus increasing thermal transfer properties. The shape and size may be selected based on the shape and size of the ice core and/or beverage container.

In general, the length of the ice core tubeis equivalent to the length of a side wallof the ice core bodythat joins the first endwith the second end. As shown in, the ice core tubecan be located in a center portion of the ice core body. In this manner, as described below in more detail, a straw can be inserted through the ice core tubeto a base portion of a beverage container that is configured to receive the ice core. This allows the straw to position the ice corewithin the beverage container, and additionally access the most chilled portion of the liquid in the base region of the container. In one embodiment, the ice core tubecan have a diameter of a half inch. It is understood that this represents one possible tube dimension and is not meant to be limiting to the various embodiments.

The ice corecan also include an ice core housingto house the ice core body, the ice core rimand the ice core tube. In one embodiment, the ice core housingcan take the form of a thin-walled, hard shelled disposable container made of a biodegradable material (e.g., a plastic, a cellulose material, bamboo, hemp, recycled material, or the like). In one embodiment, the ice core housingcan include a coverformed over the top surfaceof the ice core rim, the second endof the ice core body, and the ice core tubeextending therebetween. In this manner, the covercan enclose a frozen liquid (e.g., ice) formed within the ice core body and the ice core rim and the opening extending through the ice core body and the ice core rim that is devoid of the frozen liquid.

In one embodiment, a cover can be applied over the second endof the ice core body. In one embodiment, this cover can comprise a pierceable material. For example, the material can include any of a number of plastic materials that are strong enough to provide a seal but at the same time being pierceable. As shown in, the coverformed over the top surfaceof the ice core rimand the second endof the ice core bodycan comprise a slitthereon for receiving a straw therethrough to access an interior of the beverage container and the ice core including the ice core tube once placed in the container.

One embodiment of the present invention includes a method of making the ice core for use with a beverage container. The method includes obtaining an ice core housinglike that shown in. Although not shown in these figures for clarity, the ice core housing can have a bottom portion, an open top portion and a side wall joining the bottom portion with the top portion. It is understood that these elements would abut corresponding portions of the ice corethat is housed by the housing. For example, the second endof the ice core bodycan be placed in the bottom portion the of the ice core housingwith the first endof the ice core bodyand the ice core rimfacing the open top portion of the ice core housing.

After housing the ice corewith the ice core housing, it can then be filled with a liquid for subsequent freezing into a frozen substance. In one embodiment as depicted in, the ice core can be filled with particles of frozen liquid and liquid to bind the particles together. In one embodiment, the ice corecan first be partially filled with particles of frozen liquid (e.g., shaved ice) and then filled thereover with a liquid (e.g., water) to fill in any gaps that exist between the particles in the ice core. In one embodiment, the particles of frozen liquid and liquid fill in parts of the ice corethat include the ice core bodyand ice core rim, leaving the ice core tubedevoid of any frozen particles and liquid.

A portion of the ice core housing with the ice core therein can then be sealed with a lid or coverafter providing sufficient liquid to the particles of frozen liquid. In one embodiment, a sealing machine can be used place a sealed lid or cover over the ice core housing with the ice core therein and filled with the liquid and the particles of frozen liquid. The sealed lid or covercan comprise a pierceable material as noted above. In addition, a cover can be sealed over the bottom portion of the housing. The sealing machine can include any now known or later developed cup sealing machine such as readily available commercial sealing machine that can create a tight seal with the use of a special plastic film that can melt and create a vacuum-like seal to prevent spillage of the contents from the cup.

After the sealing, the method can continue with freezing the sealed ice core housing with the ice core filled with liquid and particles of frozen liquid for a predetermined period of time to form the frozen ice core. In this manner, the frozen ice core can be continued to be stored and ready for future use in chilling liquid in a beverage container.

shows a schematic of the ice coredeposited in a beverage containerto form an ice core beverage containeraccording to an embodiment of the invention. As illustrated in, the ice core beverage containercan include a base region, a top regionand a side wallthat joins the base region with the top region. In this manner, the base region, the top regionand the side walltogether define a space for receiving a liquid. The top regioncan have a diameter that is larger than the diameter of the base region. To this extent, as shown in, the diameter of the ice core beverage containerdecreases progressively from the top regionto the base region. However, in other embodiments, the diameter of the top regionmay be the same as the diameter of the base regionor the diameter of the top regionmay be greater than the diameter of the base region.

The arrangement where the diameter of the top regionis greater than the diameter of the base regionmay ensure that the beverage remains at the bottom and will be continually chilled until the beverage is finished. This is in part due to the conduction and convection effects that the coolest drink will sink to the bottom of the cup and there is no reason to design a thicker ice core to cool empty space above the beverage. It is understood that the beverage containerrepresents only type of container and is not meant to be limiting, as the various embodiments are suitable for use with a variety of containers.

The aforementioned ice coreis configured for placement in the beverage container. As shown in, the top surface of the ice core rim and the first end of the ice core body can face the base regionof the ice core beverage containerand the bottom surface of the ice core rim and the second end of the ice core body can face the top regionof the beverage container. With this placement, the rolled outward rimof the ice core rim is configured to lodge against the side wallof the ice core beverage containeras a level of liquid in the beverage container diminishes to a point where the ice coreis unable to float in the liquid. In this manner, the rolled outward rimof the ice core rim can adhere to the side wallat a location where the length of ice core rim corresponds with the diameter of the side wall, leaving a space between the ice core rim and the base regionof the ice core beverage container.

In one embodiment, the rolled outward rimof the ice core rim of the ice core can be used with a beverage containerthat is sized to provide approximately half an inch of space between the bottom of the ice core and the base region of the container. Such a spacing will allow a straw to extend to the inside bottom of the container to freely sip the remaining liquid.

shows a strawcan be inserted through the ice core bodyto have access to the base regionof the beverage container to allow one to be able drink the coldest portions of the liquid that remain in the container. In one embodiment, the strawcan be inserted through the ice core tube. With the strawinserted through the ice core tube, the straw can be used also to position the ice corewithin the beverage containerwhile it is floating on the liquid in the container. It is understood that the strawis not limited for placement only within the ice core tube. For example, instead of placing the straw through the ice core tube to extend through the top region to the base region of the beverage containerto access liquid at the base region, the straw can be inserted in the container itself as opposed to within the ice core (e.g., adjacent the core).

As shown in, the beverage containercan further include a lidconfigured for secure placement on the top regionof the beverage container. The lidcan also serve the purpose of directing the ice core while floating on the liquid in the beverage containerin a downward direction towards the base regionof the container as shown in. The lidcan also have a slit that is in alignment with the slitformed on the cover of the ice core housing. In this manner, the straw can be inserted seamlessly through the lidand the cover of the ice core housing to gain access into and through the ice core tube and to the base region of the container.

Other features the ice core beverage containerare apparent from the schematics shown in. For example, the ice corecan have a height from the top surface of the ice core rim to the second end of the ice core body that is less than the height of the beverage containerfrom the base region to the top region. In one embodiment, the height of the ice core can be set at about three quarters of an inch shorter than the height of the beverage container. One purpose of such a “tall” design is to allow a closed lid or sealed film to effortlessly push an ice core floating in the beverage containerin a downward direction towards the base region of the container.

The tall design of the ice core also enables an increase in the contact area that the ice core will have with the liquid. As a result, there will be an enhancement of both conduction and convection effects with the liquid throughout the entire container at same time. To this extent, the ice core will maximize the chilling effects as fast as possible. The design of the ice core with an upper end that is smaller than the lower end, not only enables chilling the liquid beverage faster at all portions of the container (especially the base region) and for a longer time, but it also obviates the problem of dilution of the liquid that arises from the use of ice cubes.

Another feature of the ice coreof the various embodiments is that it is configured for removal from the beverage containerand upending to reorient itself to a different placement within the beverage container. For example, as shown in, the different placement includes having the top surface of the ice core rim and the first end of the ice core body face the top regionof the beverage container, and the bottom surface of the ice core rim and the second end of the ice core body face the bottom regionof the beverage container. Thus, after one finishes the beverage in the container, the ice corecan then be just flipped upside down to be reoriented in the container. The strawcan then be used to pierce the plastic film seal on the ice core to get the melted icy fresh water. In this manner, consumers can continue to cool themselves down, quenching their thirst more and awakening their taste buds at the same time.

In light of the various embodiments described herein, it should be apparent that the ice core and the ice core beverage container overcome the dilution and diminished chilling time associated with a convention approach that relies solely on ice added to a liquid in beverage container. With the ice core and the ice core beverage container described in the various embodiments, zero dilution of the liquid in the beverage container is achievable, as is providing both enhanced conduction and convection effects that chill the liquid faster and keep it chilled for a longer period of time. These benefits can be advantageous with all types of drinks. One example, where the various embodiments are suitable for use is ice coffee. In particular, the ice core and the ice core beverage container of the various embodiments will allow the ice coffee to retain its original flavor from the first sip to the last drop, of which such a sensation is highly desirable to a coffee drinker.

The design of the circular hollow tube (i.e., the ice core tube) in the center of the thin-walled, hard-shell housing of the ice core not only enables a straw to reach down to the bottom of a cup easier as opposed to one that is floating on top of the beverage in a cup that is filled with blocks of ice. To this effect, the use of the straw in the ice core tube precludes problems of blocks or piles of ice in the container causing the straw to get tangled therein.

In addition, the tall design of the ice core not only chills the entire cup of the beverage faster, but the larger end of the ice core can remain at the bottom of the cup all of the time to provide a more chilled beverage for consumption via a sip of a straw from start to finish.

Further, having the ice core be disposable per one embodiment, makes its use suitable in scenarios where beverages are sold in a commercial venue. For example, upon receiving an order for a beverage that is typically served chilled (e.g., ice coffee, juice, soda, etc.), a commercial vendor can fulfill the order by filling a beverage container with both the ordered liquid and the ice core. Upon drinking the beverage and using the ice core in the aforementioned manner, the customer can then dispose of both the beverage container and the ice core when finished with the drink.

is a schematic view of an ice core or an insertbeing coupled to a lid, according to one embodiment. The lidmay include a top openingprotruding above the lid. In one example, the top openingmay protrude between.inches andinch above the lid. The top openingmay be sealed with the inner container. The top openingmay be designed to be capable of receiving a straw.

is a schematic view of an ice core or an insert coupled with a lid, according to one embodiment.shows the ice core and lid without the beverage container. The insert, as discussed above, may include an interior, hollow ice core tube. The ice core tubemay extend from a bottom of the ice core toward a top of the ice core. In one example, shown in, the ice core tubeis frustoconical in shape, however, the hollow portion may be cylindrical or another shape. The ice core tube may further include an inner tubeextending within the ice core tube. The inner tubemay provide alignment and spacing features, as well as additional cooling features. For example, the inner tube may include provide further cooling or warming material for desired temperature regulation. The lidmay include an opening endthat provides access to one or more of the ice core tube, the inner tube, and/or the beverage. The opening endmay be sized to receive one or more drinking apparatus, e.g., a straw.

The opening endmay be positioned to be integrated with the top of the inner tube and extending above the lid. The opening endmay be raised above the lid by a predetermined distance, for example, between 0.1 and 3 inches. Once the beverage is filled, the opening end may be sealed by a sealing machine. However, if the opening endand the lidwere level, it would be more difficult to seal the opening end.

The ice core can be formed of a plastic material. The ice core may have a top diameter and a bottom diameter that are the same, i.e., the ice core may be a cylinder. In other embodiments, the top diameter may be less than the bottom diameter or the top diameter may be greater than the bottom diameter. The ice core may be the same shape as the beverage container or may be different shape from the beverage container.

The opening endmay be sealed and then covered with a lid. The lid may prevent inadvertent piercing or breaking of the seal. A bottom side of the ice core may be configured to have an open portion that may be sealed with a sealing machine with, for example, a plastic covering. The top and bottom of the ice core may have openings that are sealed with a film material. Once the beverage is finished, the user may insert a straw through the sealed portions and drink icy or cool water from the interior of the ice core. In one example, once the beverage is finished, the user may turn the ice core upside down and pierce the seal of the bottom side of the ice core with a straw, such that the user may drink icy or cool water from the interior of the ice core.

In one example, the ice core or insert may be turned upside down, i.e., having a bottom side of the insert facing upwards, such that the cavity of the insert may be filled with a thermal regulating material, e.g., crushed ice. Once the thermal regulating material is placed inside the insert, the bottom side of the insert may be sealed using a sealing machine. For example, a polymer or plastic material may be used to seal the bottom side. The sealed side may then be covered with a lid, for example, a lid over the top side of the insert, the bottom side of the insert, or both. The lid may prevent the sealing accidently being pierced. The insert may be turned right side up, e.g., with the bottom side facing downward. A pre-chilled beverage may be poured into the beverage container, around the insert. This method may be a less expensive means to make the cooling insert. After the chilled beverage is finished, the user may take the bottom lid covering the inserts bottom side off, to prevent dripping of the residual beverage. The insert may then be turned upside down, and the user may use a straw to pierce the bottom surface, such that the user may be able to drink the icy or chilled water.

The lidis shown in an exploded, removed position. The lidis configured to be removably coupled with an opening of the insert. For example, the lid may have a threaded connection, as shown in, a snap fit, a press fit, a friction fit, or another coupling known in the art. The lidmay include an opening end that provides access to one or more of the insertand/or the beverage. The opening end may be sized to receive one or more drinking apparatus, e.g., a straw.

The insert, as discussed above, may include a first end having a shoulder portion. The shoulderportion may be sized and designed to rest on an upper lip of a beverage container. The shouldermay be sized to fit inside of the beverage container, in another example. As shown in, the insertmay have walls that are zig-zag shaped or formed of various shapes that may be designed to increase the surface area of the insert. As discussed previously, the increased surface area may facilitate and/or enhance the cooling or warming effects of the insert.

A bottom surface of the insertmay be sized to the same size and shape of a bottom of a beverage container. As such, the bottom surface of the insert is configured to be received by the bottom of the beverage container. In one example, the bottom surface of the insert may be integrated with the bottom of the beverage container.

is a schematic view of an ice core or an insertcoupled with a beverage containeraccording to an embodiment of the invention. The beverage containermay also be coupled with a lid, discussed above with respect to. In one example, the insertmay fit fully within the beverage container. In another example, a bottom portion of the insertmay be sized to rest on and/or be supported by a bottom surface of the beverage container. In yet another example, the shoulderof the insertmay be sized and positioned to be supported on an upper lip of the beverage container.

In another embodiment, the bottom of the beverage cup may be customized to be the same shape and capacity as the ice core/insert. The beverage cup may then be turned upside down to fill the cavity with crushed ice, and then use a sealing machine may seal the bottom. The beverage cup may then be turned over and the pre-chilled beverage may be poured into the cup, which not only enables beverage chilling but also saves the cost of making ice cups. This method is also applied when making beer cups, cocktail glasses or beer pitchers.

In another embodiment, polyethylene (PE) may be used to make the beverage cup. PE may have a heat resistance up to 110 degrees Fahrenheit. If PE is used for the beverage container, a gel-like substance (e.g., a cornstarch and boiling water mixture) may be poured into the beverage cup surrounding the ice core to heat slowly into the PE beverage container. After pouring the hot drink into the PE beverage container, more of the gel-like substance may be added, until both the beverage container and the ice core's rims are on the same horizontal. This combination can achieve a longer-lasting heat preservation effect. This hot drink cup will be ideal for drinking hot drinks in colder areas and during winter.
