BACKGROUND OF THE INVENTION
I. Field of the Invention
The invention relates to a beverage holder, and, more particularly, to a beverage holder having a housing, a heat transfer unit disposed within the housing for cooling and/or heating a beverage within the housing. People use insulated beverage holders to provide insulation to a beverage in order to maintain the temperature of the beverage. People either heat or cool their beverages to a desired temperature.
Placing the beverage within an insulated beverage housing insulates the beverage from the environment during consumption of the beverage. One type of insulated beverage holder is constructed from suitable foam configured to receive a beverage can. The foam insulation assists in maintaining the desired condition of the beverage
Certain problems exist with the aforesaid prior art beverage holders. The beverage must initially be cooled or heated to the desired temperature. Once the beverage container is removed from its chilled environment the beverage will adjust to the temperature of the environment. The insulated beverage container slows this result. It is an object of the present invention to provide a beverage holder that maintains a proper environment for sustaining the desired temperature of the beverage to allow a user to consume a beverage at the desired temperature over an extended period of time.

DETAILED DESCRIPTION
Referring to FIG. 1, the present invention relates to a beverage container for holding a beverage generally shown as 100. A housing 104 of the present invention provides a surface that partially surrounds a beverage. In one embodiment, the housing 104 has a side wall and a bottom wall that retains a beverage within the housing. The bottom wall may be an optional feature of the present invention. The side wall of housing 104 may provide an insulated surface that assists in maintaining the temperature of the beverage. The insulated side wall also limits the heat transfer from the environment and the user to the beverage. The side wall also increases the comfort of the user by limiting the heat or cold transferred to the user's hands to prevent the user's hands from direct contact with the beverage and/or beverage container. The housing 104 may be constructed from rubber, foam, plastic, metal, or other suitable materials. In one embodiment, additional insulation may be provided within housing 104. A sleeve aperture located at the top of the housing 104 allows a heat transfer sleeve to be placed within the housing for transferring heat or cold to either cool or heat the beverage.
The heat transfer unit 101 is a single unit constructed from cap 102, locking body 114, and heat transfer sleeve 110. The heat transfer unit 101 allows installation of the heat transfer sleeve 110 and cap 102 to the housing 150 as a single unit. A user may remove the heat transfer unit 101 to recharge the heat transfer sleeve 110 by either cooling or heating the heat transfer unit 101 depending upon the desired function. Removing housing 104 decreases the time needed to heat or cool the heat transfer unit 101 because of the reduced insulation due to the removal of housing 104 from the heat transfer unit 101. The heat transfer unit 101 attaches to housing 104 to secure the heat transfer sleeve 110 within housing 104.
Cap 102 releasably attaches to housing 104 to maintain a heat transfer sleeve within housing 104. Cap 102 has a beverage aperture adapted to receive a beverage or a beverage container. The beverage container may be a receptacle for holding a beverage, such as a can, bottle, cup, glass, or other type of receptacle capable of holding a beverage. The cap 102 secures the heat transfer sleeve within housing 104.
FIG. 2 shows an exploded view of the present invention. Cap 102 attaches with the attachment lip 112 of heat transfer sleeve 110 and locking body 114. Locking body 114 contacts attachment lip 112 of heat transfer sleeve 110 for attachment of heat transfer sleeve 110 to cap 102. In one embodiment, locking body 114 adhesively attaches with cap 102 to attach heat transfer sleeve 110 to cap 102. Locking body 114 may also be mated with cap 102 by a threaded attachment to attach heat transfer sleeve 110 to cap 102. Cap 102 may also be attached by tongue and groove, radio frequency welding, sonic welding, adhesive attachment, or other known methods. In another embodiment, discussed below, mounting heads found on the top of the cap body are positioned within receiving apertures of the heat transfer sleeve. A separate cap head is then attached to secure the heat transfer sleeve to the cap to form the heat transfer unit.
Continuing to refer to FIG. 2, heat transfer sleeve 110 stores a heat transfer material such as fluid, gel, or other substance that can be heated or cooled depending upon the desired effect on the beverage. In one embodiment, the present invention may cool a beverage such that the heat transfer sleeve 110 stores a coolant, including but not limited to a liquid or fluid, such as water, a gel, or a chemical that will cause an endothermic reaction. In another embodiment, the present invention may heat a beverage such that the heat transfer sleeve 110 stores a heat supplying material or a chemical that will cause an exothermic reaction.
In some embodiments, the coolant may have properties such as a low freezing point and/or maintain a cold temperature for an extended period of time. In other embodiments, the heat supplying material may have properties such as a high boiling point and/or maintain a high temperature for an extended period of time. The heat transfer sleeve 110 may also be filled with non-toxic material.
The heat transfer sleeve 110 may be constructed from plastic material including but not limited to a thermoplastic, polyethylene plastic, ethylene vinyl acetate, polypropylene, or polyethylene terephthalate. The heat transfer sleeve 110 may provide pockets adapted to store the heat transfer material. In one embodiment, the heat transfer sleeve 110 provides at least one pocket. In another embodiment, the heat transfer sleeve 110 provides vertical pockets, as shown in FIG. 2. In another embodiment, heat transfer sleeve may provide multiple pockets in a vertical orientation to prevent the heat transfer material from settling in the lower sections of the heat transfer sleeve 110. Other embodiments of the present invention may include a heat transfer sleeve with horizontal pockets, at least one spiral shaped pocket, multiple parallelogram shaped pockets, multiple pockets, or other variations. In another embodiment, the heat transfer sleeve 110 utilizes multiple hexagonal pockets in a honey combed shape. In one embodiment, the heat transfer sleeve has an inner wall and an outer wall that are sealed to store the heat transfer material.
The heat transfer sleeve 110 is preferably constructed from a pair of containment sheets ideally comprising a material that maintains flexibility at below freezing temperatures, such as, for example, a thermoplastic or similar material so that the cooling cavities may be formed by heat sealing, sonic welding, or radio frequency welding of the two containment sheets. Each of the pockets of the heat transfer sleeve has a heat transfer material capable of being cooled or heated. Preferably, each of the pockets is substantially filled with the heat transfer material. Ideally, the cooling substance comprises a freezable gel or liquid, which changes state at 20 to 32 degrees F. While water may be used as the freezable coolant, other substances which have superior cold retention properties are preferred.
Continuing to refer to FIG. 2, the attachment base 108 of cap 102 tapers inward such that the attachment base 108 is found interior of cap body 106 in one embodiment of the present invention. Attachment base 108 is designed to fit within housing 104 to secure cap 102 to housing 104. Attachment base 108 extends into housing 104 when cap 102 releasably attaches to housing 104. Attachment base 108 directs heat transfer sleeve 110 into the interior of housing 104.
In another embodiment, not shown, attachment base 108 extends outward such that attachment base 108 is located exterior of housing 104 when cap 102 releasably attaches to housing 104. In this embodiment, housing 104 directs heat transfer sleeve 110 into housing 104.
The attachment base 108 attaches to retention head 116 to secure cap 102 with housing 104 to maintain heat transfer sleeve 110 within housing 104. In one embodiment, attachment base 108 of cap 102 provides a threaded surface that engages the retention head 116 of housing 104 to secure cap 102 to housing 104. In another embodiment, retention head 116 of housing 104 provides a threaded surface that engages the attachment base 108 of cap 102 to secure housing 104 to cap 102. Other embodiments of the present invention attach the cap to housing though compression fit, a tongue and groove system, and other known releasably attachments.
FIG. 3 shows a top view of the present invention. In this embodiment, cap 102 extends outwards at least as much as housing 104. Cap head 110 tapers inward from cap body 106. Heat transfer sleeve 110 found within housing 104 lines the interior of housing 104 for contact with the beverage and/or beverage container. Heat transfer sleeve 110 forms a receiving aperture 122 within housing 104 adapted to accept a beverage and/or beverage container. The heat transfer sleeve 110 contacts the beverage and/or beverage container to affect the temperature of the beverage. One embodiment of the present invention provides a removal aperture 124 adapted to allow easier insertion and removal of a beverage container into the receiving aperture 122. The removal aperture 124 provides a pathway for removal of trapped gas under the beverage container to ease insertion of the beverage container into housing 104. The removal aperture 124 is large enough to allow a user to insert his finger to adjust the beverage container within housing 104. The removal aperture 124 also allows a user to remove the beverage container out of housing 104 by applying force from the underside of the beverage container. The removal aperture may be optional as some uses of the present invention may not require the removal aperture.
FIG. 4 shows a bottom view of the present invention. The housing bottom 125 provides an inner base 128 and an outer base 126. In one embodiment, inner base 128 extends upward toward receiving aperture 122 to increase a user's access to the underside of a beverage container through removal aperture to simplify removing the beverage container. Outer base 126 balances housing 104 on a support surface. Outer base 126 may be formed as a contiguous part of housing 104 or may be an additional structure formed from a non-skid material such as a thermoplastic elastomer (TPE). In addition, housing bottom 125 provides removal aperture 124 to enable user to remove a beverage container from housing 104.
FIGS. 5 and 6 show a cross section view of the present invention. Cap 102 releasably attaches to housing 104. Attachment base 108 of cap 102 narrows such that attachment base 108 fits within housing 104 for securing cap 102 to housing 104. Heat transfer sleeve 110 lines the interior of housing 104 to either directly or indirectly contact beverage within housing 104 to adjust the temperature of the beverage.
FIG. 6 shows an enlarged view of the attachment of the cap 102 to housing 104 and fastening of the heat transfer sleeve 110 to the cap 102. Attachment lip 112 is secured between cap head 120 and locking body 114. In one embodiment of the present invention, luting may be found below the attachment of locking body 114. Attachment base 108 of the cap 102 extends inward from cap body 106 to allow the exterior of cap body 106 to be flush with the exterior of housing 104. Attachment base 108 is sized to fit inside of housing 104. Attachment base 108 is threaded to attach the threaded portion of retention head 116. Housing 104 secures attachment base 108 such that attachment base 108 is stored essentially flush with retention neck 118 of housing 104. As noted above, the cap may be attached to the housing by other known methods including but not limited to compression fit, tongue and groove, and other known attachment methods.
FIGS. 7 and 8 show another embodiment of the present invention. Cap head 130, shown in FIG. 10, attaches to cap body 132 to form a cap. Cap head 130 attaches to cap body 132 such that cap head 130 will rotate with cap body 132 during rotation. To secure cap head 130 with cap body 132, attachment finger 136 inserts into attachment aperture 131 to allow for rotation of cap head 130 with cap body 132. FIG. 12 shows one embodiment of the cap body 132. Mounting heads 134 of cap body 132 further secure cap body 132 to cap head 130. Mounting heads 134 protrude upwards to be inserted into mounting apertures found on the underside of cap head 130. The mounting heads 134 extend upwards into the mounting apertures. In another embodiment, the attachment finger may be located on the cap head and the attachment aperture may be located on the cap body. Likewise, the mounting heads may be placed on the cap head and the mounting apertures may be placed on the cap body.
Mounting heads 134 also extend upwards to secure the heat transfer sleeve 140 to cap. Heat transfer sleeve 140 provides an attachment lip 144 with attachment apertures 146. The attachment lip 144 protrudes outward laterally to extend outward from heat transfer sleeve 140. Because attachment lip 144 extends outward, heat transfer sleeve 140 inserts into cap body 132 to allow heat transfer sleeve 140 to be placed within housing 150. As shown in FIG. 8, attachment lip extends outwards above the top of cap body 132 for insertion of mounting heads 134 through the attachment apertures 146. The mounting heads 134 pass through attachment apertures 146 before being inserted into the mounting apertures 152 of cap head 130 to secure the attachment lip 144 between the top of body 132 and the interior of cap head 130. The cap body 132 and cap head 130 attach to each other to form the cap with the heat transfer sleeve 140 secured within. In one embodiment, cap body 132 may be attached to the cap head 130 by attachment methods including but not limited to adhesive attachment, threaded attachment, tongue and groove attachment, sonic welding, radio frequency welding, or applied adhesive.
The cap head 130, cap body 132 and heat transfer sleeve 140 secure to one another to form a heat transfer unit 154, a cooling unit or a heating unit, depending upon the function desired by the user as shown in FIG. 14. FIG. 8 shows the attachment of the heat transfer unit 154. The heat transfer unit 154 is a single unit that may be installed and removed from the housing 150. A user may remove the heat transfer unit 154 to recharge the heat transfer sleeve 140 by either cooling or heating the heat transfer unit 154 depending upon the desired function. Removing housing 150 decreases the time needed to heat or cool the transfer unit because of the reduced insulation due to the removal of housing 150 from the heat transfer unit 154. The heat transfer unit 154 attaches to housing 150 to secure the heat transfer sleeve 140 within housing 150. Attachment base 138 provides a threaded surface to engage a threaded surface of retention head 148. The threaded connections of the attachment base 138 and retention head 148 secure the cap to the housing 150. The threaded attachment may be a regular threaded connection or a reversed threaded connection. As noted above, other methods of attachment of the cap to the housing may be utilized including but not limited to compression fit, tongue and groove, a releasable attachments, and other methods of attachment.
Continuing to refer to FIGS. 8 and 11, the pockets 142 store the heat transfer material including but not limited to a liquid, a gel, water or other substance that can be heated or cooled depending upon the desired effect on the beverage. In one embodiment, pocket walls 160 form each pocket 142. Other embodiments of the present invention may include a heat transfer sleeve with vertical pockets, horizontal pockets, at least one spiral shaped pocket, multiple parallelogram shaped pockets, multiple pockets, or other variations. The pocket walls may be formed by attachment of the inner wall and outer wall of the heat transfer sleeve. The pocket walls 160 retain an amount of the heat transfer material within each pocket 142. Pocket apertures 158 allow the heat transfer material to flow from pocket 142 to pocket 142. The pockets 142 formed by the pocket walls 160 decrease production costs and reduce production time due to the ease of filling each heat transfer sleeve 140. The multiple pockets also allow for uniform distribution of the heat transfer material through the heat transfer sleeve.
FIG. 9 shows the attachment of cap head 130 and cap body 132. Attachment finger 136 inserts into attachment aperture 131. The insertion of attachment finger 136 into attachment aperture 131 allows cap head 130 to rotate with cap body 132 when the two are combined to form the cap. FIG. 9 also shows the bottom of the heat transfer sleeve 140. Bottom pockets 162 are also formed by pocket walls 160. However, the bottom pockets 162 have pocket apertures 158 between the two adjacent bottom pockets 162. The pocket apertures 158 between the bottom pockets 162 allow the heat transfer material to flow between each bottom pocket 162. In another embodiment, the heat transfer sleeve does not have bottom pockets such that the bottom of the heat transfer sleeve is open.
FIG. 13 shows a cross sectional view of housing 150. Housing 150 provides a receiving aperture 164 that stores a portion of the heat transfer sleeve 140. Retention head 148 provides a threaded surface of housing 150 for attachment of the heat transfer unit 154 to housing 150. FIG. 15 shows another embodiment of housing 166 that provides a metal interior 168. The retention head 170 is also constructed from metal. The metal interior is coated with an insulating surface 170 constructed from foam, EVA foam, or other insulating material such as silicone, polyurethane, or ceramic materials.
The housing may be constructed from a semi-rigid including but not limited to EVA plastic, and compression molded foam. The housing may also be constructed from a rigid material such as a metal or stainless steel covered in foam, EVA foam, or other insulating material such as silicone, polyurethane, or ceramic materials. Other embodiments do not cover the housing with the foam, EVA foam, or other insulating material. In another embodiment, the threaded portions of the invention such as the retention head and the attachment base may be constructed from a rigid material such as a plastic, metal, or stainless steel.
