Description

BACKGROUND

Beverages are often consumed from beverage containers, such as bottles and cans, in environments with elevated temperatures. It is often desirable to keep such beverages cool when ambient temperatures are high. In addition, it can be desirable to insulate a holder's hand from the cold beverage container, and to improve a grip between the holder's hand and a wet surface of the beverage container with condensation. Insulated sleeves have been proposed that can surround the beverage container. It has also been proposed to use a magnet to hold the insulated sleeve with respect to a surface, such as a vehicle. Examples of such insulated sleeves are shown in U.S. Pat. Nos. 4,540,611; 5,320,249; 6,059,140; 6,286,798; 7,021,594; 7,897,088; 8,001,671; 9,578,954; D851,463; D547,618; D533,751. Such an insulated sleeve is also known as a Koozie®, a coozy, a coolie, a stubby holder, a drink caddy, a can cooler, a can cover and a can hugger. The insulated sleeve can also be utilized to distinguish beverage containers amongst a group of holders and beverage containers, and for marketing purposes. The development of coolies is an ongoing endeavor.

DETAILED DESCRIPTION

Before invention embodiments are disclosed and described, it is to be understood that no limitation to the particular structures, process steps, or materials disclosed herein is intended, but also includes equivalents thereof as would be recognized by those ordinarily skilled in the relevant arts. It should also be understood that terminology employed herein is used for the purpose of describing particular examples only and is not intended to be limiting. The same reference numerals in different drawings represent the same element. Numbers provided in flow charts and processes are provided for clarity in illustrating steps and operations and do not necessarily indicate a particular order or sequence. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.

As used in this specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a layer” includes a plurality of such layers.

In this disclosure, “comprises,” “comprising,” “containing” and “having” and the like can have the meaning ascribed to them in U.S. Patent law and can mean “includes,” “including,” and the like, and are generally interpreted to be open ended terms. The terms “consisting of” or “consists of” are closed terms, and include only the components, structures, steps, or the like specifically listed in conjunction with such terms, as well as that which is in accordance with U.S. Patent law. “Consisting essentially of” or “consists essentially of” have the meaning generally ascribed to them by U.S. Patent law. In particular, such terms are generally closed terms, with the exception of allowing inclusion of additional items, materials, components, steps, or elements, that do not materially affect the basic and novel characteristics or function of the item(s) used in connection therewith. For example, trace elements present in a composition, but not affecting the composition's nature or characteristics would be permissible if present under the “consisting essentially of” language, even though not expressly recited in a list of items following such terminology. When using an open ended term in the specification, like “comprising” or “including,” it is understood that direct support should be afforded also to “consisting essentially of” language as well as “consisting of” language as if stated explicitly and vice versa.

The terms “first,” “second,” “third,” “fourth,” and the like in the description and in the claims, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Similarly, if a method is described herein as comprising a series of steps, the order of such steps as presented herein is not necessarily the only order in which such steps may be performed, and certain of the stated steps may possibly be omitted and/or certain other steps not described herein may possibly be added to the method.

The terms “left,” “right,” “front,” “back,” “top,” “bottom,” “over,” “under,” and the like in the description and in the claims, if any, are used for descriptive purposes and not necessarily for describing permanent relative positions. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments described herein are, for example, capable of operation in other orientations than those illustrated or otherwise described herein.

The term “coupled,” as used herein, is defined as directly or indirectly connected in an electrical or nonelectrical manner. Objects described herein as being “adjacent to” each other may be in physical contact with each other, in close proximity to each other, or in the same general region or area as each other, as appropriate for the context in which the phrase is used. Occurrences of the phrase “in one embodiment,” or “in one aspect,” herein do not necessarily all refer to the same embodiment or aspect.

As used herein, the term “substantially” refers to the complete or nearly complete extent or degree of an action, characteristic, property, state, structure, item, or result. For example, an object that is “substantially” enclosed would mean that the object is either completely enclosed or nearly completely enclosed. The exact allowable degree of deviation from absolute completeness may in some cases depend on the specific context. However, generally speaking the nearness of completion will be so as to have the same overall result as if absolute and total completion were obtained. The use of “substantially” is equally applicable when used in a negative connotation to refer to the complete or near complete lack of an action, characteristic, property, state, structure, item, or result. For example, a composition that is “substantially free of” particles would either completely lack particles, or so nearly completely lack particles that the effect would be the same as if it completely lacked particles. In other words, a composition that is “substantially free of” an ingredient or element may still actually contain such item as long as there is no measurable effect thereof.

As used herein, “adjacent” refers to the proximity of two structures or elements. Particularly, elements that are identified as being “adjacent” may be either abutting or connected. Such elements may also be near or close to each other without necessarily contacting each other. The exact degree of proximity may in some cases depend on the specific context.

As used herein, the term “about” is used to provide flexibility to a numerical range endpoint by providing that a given value may be “a little above” or “a little below” the endpoint. It is understood that express support is intended for exact numerical values in this specification, even when the term “about” is used in connection therewith.

The terms “interference fit” and “friction fit” and “press-fit” are terms of art used interchangeably herein to refer to deliberately causing, increasing and/or using friction to deliberately resist movement. An interference fit or friction fit is different than and great than the existence of friction. While friction may exist between any two surfaces, is often desirable to do all one can to reduce this friction. An interference fit or friction fit can be distinguished from naturally occurring friction by being actually deliberately caused and increased. An interference fit can be created by dimensioning engaging parts so that their surfaces tightly bear against one another. A friction fit can be created by surface roughness that is rougher.

The terms “indicium” and “indicia” are used interchangeably herein, unless otherwise noted.

The terms “business”, “company” are used broadly and interchangeably herein to refer to an organization that provides a product or a service. The business, company or organization can have a name, logo, slogan, trademark, service mark, etc. that is capable of identifying and/or distinguishing the business or company, or product or service, or both, or can otherwise be utilized to market, promote, and/or brand the business or company, or product or service, or both. The indicium can be indicative of such a business, and can comprise a name, logo, slogan, trademark, service mark, etc.

An initial overview of the inventive concepts are provided below and then specific examples are described in further detail later. This initial summary is intended to aid readers in understanding the examples more quickly, but is not intended to identify key features or essential features of the examples, nor is it intended to limit the scope of the claimed subject matter.

The beverage holder can provide a light in addition to holding and insulating a beverage container. Thus, the light of the beverage holder can illuminate an area. A single hand can be used to hole both the beverage and the light. The beverage holder can have a light mount with a pair of shells, such as an exterior shell or housing, and an interior shell or backing, sandwiching a lateral wall of the beverage holder therebetween and securing a light to the beverage holder. The light can be located on a lateral side of the beverage holder to direct light laterally outwardly from the beverage holder. The beverage holder can receive a beverage container and provide illumination. In one aspect, the pair of shells can have an array of teeth penetrating the lateral wall of the beverage holder to maintain the orientation of the light mount with respect to the beverage holder with the beverage container therein.

Referring to FIGS. 1-18, a beverage holder 10 is shown in accordance with an embodiment of the invention. The beverage holder 10 can receive and hold a beverage container 14 therein while providing a light 18. The light 18 can comprise at least one light emitting diode (LED). Thus, the beverage container 14 and the light 18 can be held together with a single hand, and light from the light 18 can be directed while holding the beverage container 14. The beverage container 14 can be an aluminum can, a bottle, a thermos, an insulated or vacuum bottle, a plastic or Styrofoam cup, a glass, etc. Such beverage container 14 can have a cylindrical perimeter.

The beverage holder 10 can comprise an insulating sleeve 22 to receive, hold and insulate the beverage container 14. In one aspect, the insulating sleeve 22 can be flexible and foldable. Thus, the insulating sleeve 22 can have a cylindrical configuration and a flat configuration. For example, the insulating sleeve 22 can comprise neoprene, and can have a thicker foam layer covered by a thinner outer fabric layer. In one aspect, the insulating sleeve 22 can be cylindrical with a lateral wall 26 that can be cylindrical, and that can circumscribe the beverage container 14. In one aspect, the insulating sleeve 22 and the lateral wall 26 can be open at the top and the bottom, and can grip the beverage container 14 with a friction fit. In another aspect, the insulating sleeve 22 and the lateral wall 26 can have closed bottom with a bottom. The insulating sleeve 22 can be formed by cutting or stamping a pattern and sewing the pattern to form the sleeve. The insulating sleeve 22 can be formed of a single piece sewn into shape. In another aspect, the insulating sleeve can be rigid, and can comprise a closed-cell foam. In another aspect, the insulating sleeve 22 can have additional portions tailored to a particular beverage container, such as an inverted frusto-conical top adapted for a long neck bottle. In another aspect, the insulating sleeve 22 can have other novelty shapes. In another aspect, the insulating sleeve 22 and the lateral wall 26 can have fasteners, such as buttons, shoe-lace or a zipper, to close the insulating sleeve 22 and the lateral wall 26 about the beverage container 14 and to cinch and grip the beverage container 14. In one aspect, the insulating sleeve 22 has at least a cylindrical portion to circumscribe at least a portion of a cylindrical portion of the beverage container 14. The insulating sleeve 22 can be flexible and resilient, such as elastic, to stretch and expand to receive the beverage container 14 and retract about the perimeter of the beverage container 14.

In addition, the beverage holder 10 can comprise a light mount 30 to secure the light 18 to the insulating sleeve 22 with the beverage container 14 therein, and to position the light 18 on a lateral side outwardly with respect to the insulating sleeve 22 and the lateral wall 26. In one aspect, the light mount 30 can carry and position at least one light 18 on an exterior of the insulating sleeve 22. In another aspect, the light mount 30 can be rigid to maintain an orientation of the light 18. In one aspect, the light mount 30 can comprise a housing such as a pod, case, encasement, casing, capsule, sheath, cover, etc. The light mount 30 can comprise a pair of shells, such as a pair of housing portions, including an exterior shell and housing 38, and an interior shell and backing 42. The pair of shells, and the exterior housing 38 and the interior backing 42, can carry the light 18, position the light 18 on a lateral exterior of the insulating sleeve 26, and sandwich a portion of the insulating sleeve 26 between the pair of shells; thus mounting the light 18 to the insulating sleeve 26.

The exterior shell and housing 38 is located outside the insulating sleeve 22 and on the lateral wall 26 of the insulating sleeve 22. The light 18 can be carried by the exterior shell and housing 38 and located outside of the insulating sleeve 22 and lateral wall 26 thereof. The interior shell and backing 42 can be located on an interior of the insulating sleeve 22 and the lateral wall 26 thereof. The pair of shells, and the exterior shell and housing 38 and the interior shell and backing 42, sandwich a portion of the lateral wall 26 of the insulating sleeve 22 therebetween.

The pair of shells, and the exterior shell and housing 38 and the interior shell and backing 42, are fastened and joined through the insulating sleeve 22 and the lateral wall 26. At least one fastener 46 can be carried by the pair of shells 38 and 42 and can extend through at least one aperture 50 in the lateral wall 26 of the insulating sleeve 22 to couple the pair of shells 38 and 42 together. In one aspect, the fastener 46 can comprise an array of fasteners, and the aperture 50 can comprise an array of holes. The fastener 46 can include a portion carried by the interior shell and backing 42 engaging another portion carried by the exterior shell and housing 38. One of the portions can comprise a finger 54 with a hook 56, and another of the portions can comprise a cavity 60 with a tab 62 (FIG. 12) engaged by the hook 56 of the finger 54. Thus, the pair of shells 38 and 42 can be pressed together, with the finger 54 deflecting as the hook 56 engages the tab 62, and then returning as the hook 56 passes the tab 62, so that the tab 62 retains the hook 56. The fastener 46 can be a snap-fit. In one aspect, the beverage holder 10 can be provided with the light mount 30. In another aspect, the light mount 30 can be provided separately to retrofit an existing beverage holder 10 or insulating sleeve 22 without a light mount.

The pair of shells 38 and 42, and the interior sides thereof, can have a gap 66 (FIG. 4) therebetween. In one aspect, the gap 66 between the pair of shells 38 and 42 can be smaller than a thickness of the lateral wall 26 of the insulating sleeve 22. The insulating sleeve 22 and the lateral wall 26 can comprise a material that is elastic, and that is flexible and resilient. Thus, the pair of shells 38 and 42 can compress the lateral wall 26, and the lateral wall 26 can bias the pair of shells 38 and 42 outwardly to help maintain the engagement of the fastener(s) 46, and the engagement of the hook 56 and the tab 60.

In another aspect, the pair of shells 38 and 42 can have at least one array of teeth 70 and 72 carried by at least one of the exterior shell and housing 38 and the interior shell and backing 42. In one aspect, the outer shell and housing 38 can have the array of teeth 70. In another aspect, the inner shell and backing 42 can have the array of teeth 72. In another aspect, both shells 38 and 42 can have the array of teeth 70 and 72, respectively. The array of teeth 70 and 72 can penetrate into the insulating sleeve 22 and the lateral wall 26 to help maintain the relative position of the shell 38 or 42 with respect to the lateral wall 26. The array of teeth 70 and 72 can circumscribe and be arrayed around a perimeter of the shell 38 and 42, respectively. The teeth of the array of teeth 70 and 72 can be pointed, and can extend from an interior side of the respective shell 38 and 42.

As discussed above, both of the exterior shell and housing 38 and the interior shell and backing 42 can carry arrays of teeth 70 and 72, respectively, penetrating into the insulating sleeve 26. In one aspect, the array of teeth 72 of the interior shell and backing 42 and the array of teeth 70 of the exterior shell and housing 38 can be off-set with respect to one another, and the teeth of the arrays 70 and 72 can be intermeshed and off-set. For example, a tooth of the interior shell and backing 42 can extend between a pair of adjacent teeth of the exterior shell and housing 38. Thus, the teeth of the arrays 70 and 72 can alternate with respect to one another around the perimeter of the magnetic mount 30 for improved grip. This allows the teeth to be longer without interfering with one another.

The exterior shell and housing 38 can have an interior side 76 with a concave shape, as shown in FIG. 11. The concave shape can be elongated along a longitudinal axis 80 parallel with a longitudinal axis 84 of the insulating sleeve 22 defined by the lateral wall 26 when in a cylindrical shape. Thus, the concave shape of the interior side 76 of the exterior shell and housing 38 can more closely conform to a curvature of the exterior of the lateral wall 26 of the insulating sleeve 22. The center teeth 88 of the array of teeth 72 nearer a center of the interior shell and backing 42 that are parallel with the longitudinal axis 84 can be taller than other teeth 90 of the array of teeth 72 further from the center. Thus, the height of the teeth of the array 72 of the interior shell and backing 42 can accommodate the concave shape of the exterior shell and housing 38.

In addition, the beverage holder 10 and the light mount 30 can have a dome 94 carried on the exterior shell and housing 38 of the pair of shells. The dome 94 can cover the light 18 to provide protection to the light 18. The light 18 can be at least one LED disposed on a circuit board 98 carried by and disposed in the exterior shell and housing 38. The dome 84 can cover the circuit board 98 as well. A switch 102 can be carried by the circuit board 98, and can extend to or through an aperture 104 in the dome 94. A battery 106 can be carried by the light mount 30 and coupled to the switch 102 and the light 18. The battery 106 can be carried by the exterior shell and housing 38. The battery 106 can be carried on the circuit board 98. The battery 106 can be a rechargeable battery. The battery 106 can be charged through a port 108 in the side of the exterior shell and housing 38.

As described above, the beverage holder can comprise at least one light, and the light can be an LED. In another aspect, the light can be an array of LEDs. Thus, the dome 94 can be elongated and can be a hemispherical capsule to accommodate the linear array of LEDs. The switch 102 and the aperture 104 can be located at one end of the elongated dome 94 or capsule.

In one aspect, the beverage holder 10 and the light mount 30 can have indicia. The indicium can be indicative of or represent a business, a product, or both. Thus, the beverage holder 10 can be used as a promotional product. The indicia can include sleeve indicium 110 carried by an exterior of the insulating sleeve 22. In addition, the indicia can include light indicium 114 carried by the light mount 30, such as under the dome 94. Thus, the dome 94 can protect the indicium 114. In another aspect, the indicia can be matching indicia with the sleeve indicium 110 and the light indicium 114 matching one another.

In another aspect, the pair of shells 38 and 42 can be oblong. Thus, the dome 94 can be oblong as well.
