A koozie ( /ˈkuːzi/ KOO-zee) (US) or stubby holder (Australian) is a fabric or foam sleeve that is designed to thermally insulate a beverage container, like a can or bottle.
Name, origin, and trademark dispute
[edit]The name "Koozie", with a capital "K", is a federally registered trademark in the United States,[1] originally coined by Bob Autrey of San Antonio, Texas, and rights later sold to Radio Cap Corporation (RCC) as the KOOZIE in the early 1980s. The company RCC specialized in baseball caps before registering a trademark for the name KOOZIE in 1980, and subsequently introducing the product as a can cooler in 1982. As the promotional product industry grew, more products were added to the KOOZIE brand, including drinkware, more styles of can coolers, cooler bags, outdoor leisure items, travel accessories, and business accessories. The word koozie has also lost its trademark numerous times over the years, making it a regular everyday word in the English language, similar to words like onesie, zamboni, and hula hoop. These are brand name products that have been subject to genericide—"the process by which a brand name loses its distinctive identity as a result of being used to refer to any product or service of its kind."[2]
Norwood Promotional Products acquired RCC in 1991 and continued to grow the KOOZIE line of products. In 2009, BIC Graphic purchased Norwood and its sub-brands. BIC Graphic dropped the "RCC" in favor of the KOOZIE brand name and expanded the line to include additional styles of can coolers, cooler bags and totes, as well as housewares.[3]
Norwood was in a dispute, on-and-off over several years in the 2000s, over the Koozie trademark status with an online retail business called Kustom Koozies. Norwood asserts that names such as beer hugger, can cooler, and huggie do not infringe its trademark, but that koozie, coozie, coolie, and cozy do.[4][5] Kustom Koozies asserted in 2005 that the trademark had become generic.[4][5] In the years since, Norwood and Kustom Koozies came to a licensing agreement over the use of the trademark, but by 2009 they were in dispute again, as Kustom Koozies tried and failed to cancel the trademark licensing agreement in response to Norwood instructing it to make certain changes to its website, one of which was that "Koozie" should be set out in all-capital letters as "KOOZIE," and another being that the registered trademark symbol "®" be used to identify genuine Norwood KOOZIE brand beverage sleeves.[6]
In December 10 2025, a Newfane family business called ‘ Better Wheel Workshops’ which makes wooden can insulators originally known as the “Woodzie” settled a trademark dispute with the Koozie Group, which holds a trademark to the word “koozie”, the conditions being that the “Woodzie” be renamed to “Tree Sleeves”. Better Wheel Workshops has been making the wooden can insulators for a decade before they were informed about a year-and-a-half ago that the Koozie Group filed a petition with the U.S. Patent and Trademark Office to cancel the “Woodzie" trademark over potential confusion.[7]
In Australia, the beverage insulator is called a stubby holder because local beer was traditionally sold in 375 mL (13.2 imp fl oz; 12.7 US fl oz) bottles colloquially known as "stubbies" due to their short, squat appearance in comparison to the alternative packaging of 750 mL (26 imp fl oz; 25 US fl oz) bottles ("king brown", "tallie", or simply "bottle"), and the 300 to 375 mL (10.6 to 13.2 imp fl oz; 10.1 to 12.7 US fl oz) longneck bottles commonly used for beer imported from North America and Europe. Most Australian domestic beers have now adopted longneck bottles and/or aluminium cans ("tinnies") for their 375 mL (13.2 imp fl oz; 12.7 US fl oz) packaging, and 750 mL (26 imp fl oz; 25 US fl oz) bottles are now sold much less commonly than was the case historically. Victoria Bitter (VB) is notable for continuing to use the traditional stubby, albeit with a twist top replacing the traditional crown seal.
Use
[edit]Koozies are used to insulate a chilled beverage from warming by warm air, sunlight, and body heat. Using a koozie can reduce the rate a drink warms in the sun by up to 50%.[8]
These items can also be used for easily identifying one's beverage from another person's and for marketing or for minimizing the condensation on the can. By imprinting on the koozie, many different companies have used the koozie as a promotional giveaway because it is not only inexpensive to manufacture, but its frequent use is more likely to bring the company's name to a household presence. Originally a logo or image was screen-printed on a round foam cylinder with a foam base, which generally has a hole at the base to ease inserting and removing beverage containers.
Materials and styles
[edit]The koozie has evolved in both material and style. Materials used include leather, neoprene, EVA, polyester, vinyl, and various open-cell and closed-cell foams. There are koozies for 40 oz. bottles, and adjustable koozies that fit different beverage container sizes.

Overview
Definition and Purpose
A koozie is a sleeve or holder engineered to fit snugly around standard beverage containers, such as 12-ounce cans or longneck bottles, serving as a thermal insulator to minimize heat transfer between the drink and its surroundings. This design creates a barrier that slows the conductive flow of heat, preserving the beverage's temperature whether cold or hot.[8][9] The core mechanism relies on principles of thermal insulation, where the koozie reduces direct contact with warmer external air or the user's hand, thereby limiting warming of cold beverages. It also prevents excessive condensation on the container's exterior, as water droplets forming from humid air release latent heat that accelerates temperature rise—without insulation, this can warm a drink by about 6 degrees Fahrenheit in five minutes under typical humid summer conditions. In ambient environments, this insulation extends the time a cold drink remains chilled compared to an unprotected container.[10][9] Primarily intended for temperature retention, koozies offer secondary advantages like enhancing grip by absorbing moisture from condensation to prevent slippage and providing a cushioned layer that offers minor protection against light impacts or spills. Standard sizes for can koozies measure approximately 4 to 6 inches in height and 4 inches in width to fully encase a 12-ounce can, while bottle variants often include adjustable features to accommodate different shapes and sizes.[11][12]Basic Components
A standard koozie features a core structure consisting of a cylindrical sleeve body, open at both the top and bottom to facilitate the insertion and removal of beverage containers such as cans or bottles. This design allows the koozie to fully encase the sides of the container while permitting access to the contents without obstruction.[13][14] Many koozies include an optional closed bottom, typically made from a non-skid material, to capture condensation drips and prevent them from marking surfaces. This feature enhances practicality by containing moisture that would otherwise accumulate from chilled drinks. Side seams, formed during manufacturing, provide essential durability by reinforcing the sleeve against wear from repeated use and handling.[15][16][17] To ensure a secure fit, koozies employ fitting mechanisms such as the inherent elasticity of materials like neoprene, which stretches slightly to grip the container, or a tapered design that narrows toward the bottom for added stability without slippage. These elements allow the koozie to conform snugly to standard 12-ounce cans, which have a diameter of approximately 2.6 inches, with the sleeve's inner diameter typically ranging from 2.5 to 3 inches for compatibility. The height generally measures 4 to 5 inches to match the container's length, providing full coverage for optimal insulation.[18][19][20] In assembly, the basic components are joined via sewn or glued edges to form a seamless cylindrical insulator, with seams often reinforced for longevity—sewing involves stitching along the sides after patterning the material, while gluing uses adhesive to bond edges securely, particularly in foam-based versions. This process ensures the koozie maintains its shape and insulating properties over time.[21][17]History
Early Origins and Influences
The concept of insulating beverages has roots in 19th-century Britain, where knitted tea cozies emerged as practical covers for teapots to retain heat and prevent cooling during afternoon tea rituals. First documented in the 1860s, these cozies were typically handmade from wool or fabric, reflecting a cultural emphasis on prolonging the warmth of brewed tea in an era when hot beverages were central to social gatherings. This tradition of thermal wrapping laid foundational principles for later adaptations in portable insulators, shifting the focus from heat retention to cold preservation for individual drinks.[22] In Australia, informal precursors to modern beverage holders appeared in the mid-20th century, particularly from the late 1960s onward, as "stubby holders" developed to safeguard short glass beer bottles—known as stubbies—from breakage and rapid warming in the country's hot rural and outback climates. These early versions, often crafted from simple foam or fabric by locals in arid regions, addressed practical needs during outdoor labor and leisure, where extreme temperatures could quickly spoil chilled beer. The stubby bottle itself, introduced around 1964, spurred such innovations, with the first printed references to holders appearing by 1970 in popular media.[23][24] Across the Pacific, in the United States, the post-World War II explosion in canned beer production created widespread demand for portable cooling solutions beyond traditional bottles. Annual U.S. output surged from about 500 million cans in 1946 to over 10 billion by the late 1950s, fueled by rising recreational activities.[25]Patenting and Commercial Introduction
The formal patenting of the modern koozie occurred in 1981 when Bonnie McGough, an inventor from Idaho, was granted U.S. Patent No. 4,293,015 for an "insulated beverage cozy."[26] This patent, filed on June 10, 1980, and issued on October 6, 1981, described a cylindrical sleeve with inner and outer fabric walls forming compartments filled with goose down or similar insulation, including a bottom chamber, designed specifically for 12-ounce beverage cans to maintain temperature and absorb condensation. The top opening featured an elastic band for a snug fit.[26] Commercial introduction followed closely, with the Radio Cap Corporation (RCC), a Texas-based company originally focused on baseball caps, registering the trademark "KOOZIE" in 1980 and launching the first styrofoam koozie in 1982. In 1979, a Texas construction worker reportedly used pipe insulation to keep soda cans cool and hands dry, inspiring the design acquired by RCC the following year.[5][4] RCC's initial koozies were simple black foam cylinders produced from styrofoam, transitioning the concept from informal adaptations to standardized, mass-produced items suitable for widespread use.[5] This marked the entry into the promotional products market during the 1970s-1980s, leveraging the growing demand for branded accessories in the beverage industry.[27] Early production emphasized customization, with screen-printing of logos beginning in the 1980s to target breweries, corporate events, and outdoor gatherings, transforming the koozie into an effective advertising medium.[27] These printed versions allowed for quick, cost-effective personalization, aligning with the era's expansion in promotional marketing and helping to establish the product beyond regional novelty.[27] A key milestone came by the mid-1980s, when RCC achieved national U.S. distribution for Koozie products, fueled by the broader surge in outdoor recreation participation that boosted interest in portable drink insulators.[5] This period saw diversified production lines, including additional cooler styles and accessories, solidifying the koozie's role in American leisure culture.[5]Nomenclature and Legal Status
Etymology and Regional Terms
The term "koozie" is believed to derive from the English word "cozy" or "cosy," referring to a padded or knitted covering used for thermal insulation, such as traditional tea cosies, with a "K" added for branding purposes.[28][29] This linguistic root traces back to Scots origins for insulating items, adapted in the late 20th century to describe beverage insulators.[28] The name "Koozie" was first trademarked and popularized in 1980 by the Radio Cap Corporation (RCC), a Texas-based company that shifted from manufacturing baseball caps to producing foam can coolers.[7][5] Over time, "koozie" has become a genericized trademark in the United States, similar to "Kleenex" for facial tissues, referring broadly to any insulating sleeve for cans or bottles despite ongoing branding efforts.[30][31] In the United States, regional and colloquial variations include "can cooler," emphasizing its practical function; "beer sleeve," highlighting its typical use with beer cans; and "huggie" or "beer huggie," evoking the way it wraps around the container like an embrace.[32][31] Australia employs the term "stubby holder," originating in the mid-1970s to accommodate the country's standard 375 ml "stubby" beer bottles, with the earliest printed reference appearing in 1970.[23][33] This name reflects the shorter bottle size introduced in the mid-20th century, distinguishing it from taller formats elsewhere.[34] In the United Kingdom and Canada, the device is commonly known as a "can insulator," a descriptive term focusing on its thermal properties, while marketing contexts worldwide may use "chill sleeve" to promote its cooling effect.[35][36]Trademark History and Disputes
The Radio Cap Corporation (RCC) registered the "KOOZIE" trademark with the United States Patent and Trademark Office (USPTO) on December 16, 1980, under registration number 1143428, for foam insulators designed to keep beverage cans cold.[37] This registration covered neoprene and foam sleeve products, marking RCC's effort to protect the branded name following its commercialization of the item in the early 1980s.[30] In December 2001, the original trademark lapsed due to RCC's failure to file a required renewal affidavit, leading to its cancellation by the USPTO and rendering the term "Koozie" eligible for generic use in the early 2000s.[37] This lapse occurred after RCC had been acquired by Norwood Promotional Products in 1991, but the new owner did not maintain the registration, allowing widespread adoption of the term by competitors for similar foam beverage insulators.[2] Post-lapse, RCC's successors, including Norwood and later BIC Graphic (now Koozie Group, acquired by Mill Point Capital in April 2025), initiated several lawsuits in the 2000s to reclaim control over the mark. For instance, in 2005 and 2006, Norwood sued online retailer Kustom Koozies for trademark infringement over unauthorized use of "Koozie" on non-RCC products, resulting in settlements that restricted the competitor's branding.[38] Additional disputes arose, such as a 2011 declaratory judgment action by JB Originals against Norwood in the U.S. District Court for the Middle District of North Carolina, where the plaintiff argued that "Koozie" had become a generic term unprotected by trademark law due to the prior lapse and common usage.[39] These cases highlighted ongoing tensions, with courts often examining evidence of genericization, such as consumer surveys and dictionary inclusions, to determine enforceability.[40] Following these disputes, Scribe OPCO revived the trademark through new USPTO filings, including serial number 76573657 registered on May 15, 2007, and renewed in 2016 for insulated beverage containers, establishing a family of active marks that license the term for specific promotional uses while acknowledging its semi-generic status in everyday language (active as of November 2025).[41] This revival has not fully prevented generic use, as evidenced by third-party brands like Yeti opting for alternatives such as "Rambler Colster" to avoid infringement risks and differentiate their stainless-steel can insulators in the market.[30] The overall impact has fostered a landscape where "Koozie" functions as public domain slang for the product category, encouraging diverse branding strategies among competitors, with ongoing enforcement such as a 2025 petition against the "Woodzie" mark.[3][42]Design and Construction
Materials Used
Koozies are primarily constructed from synthetic foam materials that provide effective thermal insulation and moisture resistance. Ethylene-vinyl acetate (EVA) foam, a closed-cell polymer, is widely used due to its lightweight structure and ability to prevent water condensation from forming on beverage containers.[43] This material offers a thermal conductivity of approximately 0.033 W/m·K, contributing to an R-value of around 4 per inch of thickness, though in typical koozie applications (about 1/4-inch thick), the effective insulation is scaled to an R-value of roughly 1-2.[44] Neoprene, a synthetic rubber also known as polychloroprene, serves as another primary material, prized for its flexibility and durability in thicknesses of about 1/8 inch (3 mm).[45] It features a closed-cell composition that enhances water resistance and provides a thermal conductivity of around 0.054 W/m·K, with an R-value of 3.5 to 4.5 per inch.[46] Secondary materials expand the options for koozies, particularly in premium or specialized versions. Fabric blends, such as cotton or polyester, are employed for their breathability and comfort, often layered over foam cores to improve handling.[35] Leather, typically synthetic or faux variants, adds a luxurious tactile quality while maintaining basic insulation when combined with inner foam linings.[47] Silicone coatings or full silicone constructions provide enhanced flexibility and heat resistance for reusable designs.[35] Key properties of these materials include low thermal conductivity values ranging from 0.03 to 0.1 W/m·K for foams, which minimize heat transfer to keep drinks cold longer.[45] Neoprene and EVA exhibit strong UV resistance, preventing degradation from sun exposure, while their non-porous surfaces allow for easy washing and reusability without absorbing odors or stains.[48] Manufacturing of koozies has been predominantly sourced from China and other Asian countries since the 1990s, leveraging cost-effective production scales.[49] U.S.-based brands increasingly incorporate recycled inputs, such as post-consumer plastics into EVA or fabric components, to align with sustainability goals.[50]Styles and Variations
Koozies exhibit a range of styles and variations tailored to diverse beverage containers and practical needs. The most common standard style is the collapsible foam sleeve, which folds flat for compact storage and portability, making it ideal for events and promotions.[35] Another prevalent standard is the rigid plastic holder, typically featuring an internal foam lining to enhance grip and insulation while maintaining structural integrity.[51] These foundational designs accommodate standard 12-ounce cans, with dimensions often around 3.75 inches in width and 5.13 inches in height.[19] Variations extend functionality to specific container shapes, such as bottle-specific models with tapered necks for a snug fit on longneck glass bottles.[52] Zipper-closure variations, often using Velcro or zippers, facilitate reusability by allowing easy access without removing the entire insulator, commonly applied to 12-ounce bottles for full 360-degree coverage.[35] Multi-can holders represent another key variation, designed to carry multiple standard cans simultaneously, such as models that float in water for recreational use.[51] Specialized styles address niche applications, including hard-sided transporters with integrated handles for secure mobility during outings.[35] Slim-fit variations cater to narrower profiles, like those for 12- to 16-ounce energy drink or seltzer cans, ensuring a precise fit without slippage.[52] Additional specialized forms include adaptations for larger formats, such as tallboy holders for 16- to 19-ounce cans.[35] Customization plays a central role in koozie design diversity, with many styles incorporating dedicated areas for embroidery or UV printing to allow personalization.[52] These printing zones are typically 3 to 4 inches wide, providing sufficient space for logos or text on the primary surface, as seen in standard can sleeves measuring approximately 3.5 inches by 3.5 inches for imprints.[11] Such options enable adaptations across styles while preserving the core insulating form.Applications and Cultural Role
Practical Uses
Koozies serve as essential accessories for maintaining beverage temperature during casual outdoor gatherings such as barbecues, picnics, and sports events, where they insulate cans or bottles against ambient heat. By creating a barrier that reduces heat transfer and prevents external condensation, koozies help keep drinks cold for extended periods; for instance, in a test conducted outdoors at 68°F and 89% humidity, a foam koozie kept a beer's temperature 8.8°F cooler than an unprotected can after 30 minutes.[53] This functionality is particularly valuable in warm environments, allowing users to enjoy chilled beverages without frequent replacements.[54] In outdoor scenarios like tailgating, fishing, and hiking, koozies provide practical benefits by preventing hand warming from cold containers and minimizing slips caused by condensation buildup. During tailgating at sporting events, they keep drinks stable on uneven surfaces while insulating against body heat from handling.[55] Anglers and hikers use them to retain beverage chill during extended activities in variable weather, reducing the risk of wet grips that could lead to accidents near water or on trails.[56] Their lightweight design makes them ideal for portable coolers or backpacks in these settings.[57] Within households, koozies aid in fridge organization by serving as stackable holders for cans, optimizing space in crowded appliances. They also protect tabletops and furniture from water rings formed by condensation on chilled drinks, acting as a simple barrier during meals or lounging.[27] These uses extend their utility beyond outdoor events, promoting everyday convenience in domestic routines.[58]Promotional and Social Significance
Koozies emerged as effective promotional tools in the 1980s, coinciding with the rise of synthetic materials and aggressive branding strategies in the United States. During this era, companies like Radio Cap Corporation mass-produced foam and neoprene versions, transforming koozies into customizable "miniature billboards" for businesses ranging from car dealerships to breweries.[30][2] Breweries capitalized on this trend by distributing custom koozies as giveaways; for instance, Budweiser produced branded versions in the 1980s to enhance visibility at events and retail outlets.[59] As of 2025, the global can coolers market is projected to grow at a compound annual growth rate (CAGR) of 8.5% from 2023 to 2030, with annual production of approximately 500 million units, within the broader $26.6 billion U.S. promotional products industry (2024 figures).[60][61][62] Beyond marketing, koozies hold significant social value as affordable party favors at weddings, reunions, and corporate events, where they serve as personalized mementos for guests.[63] In college culture, they are staples among fraternities and sororities, often customized with Greek letters or event themes to foster group identity and camaraderie.[64] These uses underscore koozies' role as symbols of casual American leisure, evoking outdoor barbecues, tailgates, and relaxed social gatherings that emphasize informality and shared enjoyment.[65] As cultural icons, koozies appear in various media representations of everyday American life, from sitcoms depicting social drinking to films set at festivals, reinforcing their association with fun and accessibility.[66] Enthusiasts collect branded versions tied to sports teams, such as NFL franchises like the Pittsburgh Steelers, turning them into memorabilia that display fan loyalty during games and watch parties.[67] Economically, their low production cost—often under $0.50 per unit in bulk—makes them ideal swag, with studies showing promotional products like koozies achieve up to 85% brand recall among recipients, far outperforming digital ads in sustained visibility.[68][69]Modern Developments
Innovations and Sustainability
In recent years, innovations in koozie design have focused on enhancing thermal performance through advanced materials. Some modern koozies incorporate phase-change materials (PCMs) within their structure to absorb and release heat more efficiently, extending beverage cooling beyond traditional foam insulators.[70] For instance, patents describe beverage can coolers using PCM layers that maintain lower temperatures for extended periods by undergoing phase transitions.[70] Additional features in 2020s patents include integrated electronics for user convenience. Designs for soft-sided beverage insulators now allow for the addition of novelty LED lights powered by small batteries, enabling illuminated effects for promotional or recreational use.[71] Similarly, some specialized insulators, such as those for cartons, feature built-in thermochromic thermometers to monitor contents without removal.[72] These enhancements build on core insulation principles while adding functionality. Sustainability efforts in koozie production have emphasized recycled and alternative materials to minimize environmental impact. Brands like Stream2Sea produce koozies from 100% recycled neoprene sourced from wetsuits, diverting waste from landfills.[73] Other manufacturers, such as Coast Brands and Mindful Manta, upcycle discarded wetsuits into durable insulators, promoting circular economy practices.[74][75] Biodegradable options address end-of-life concerns with plant-derived foams. Crafty Can Cooler utilizes YULEX closed-cell foam, a plant-based rubber alternative that offers insulation comparable to neoprene but biodegrades naturally.[76] Experimental variants employ plant-based polyurethane foams, which break down faster than petroleum synthetics while retaining thermal properties.[45] Despite progress, challenges persist with synthetic materials like neoprene, which can shed microplastics during use and disposal, contributing to broader pollution issues.[77] In response, 2025 trends highlight zero-waste manufacturing, with companies like Koozie Group maintaining carbon neutrality and prioritizing recycled content to reduce emissions across production.[78] A key development promoting reusability occurred around 2015, when collapsible designs surged in popularity, replacing rigid single-use alternatives and aligning with anti-plastic waste initiatives.[30] These flat-folding models, often made from lightweight foam or neoprene, facilitate portability and repeated use, further supporting sustainable consumption.[79]Global Adoption and Market Trends
Koozies, known regionally as stubby holders in Australia and can cozies in parts of Europe, have seen widespread global adoption, particularly in beverage-consuming cultures emphasizing outdoor and social activities. In Australia, stubby holders are a cultural staple, ubiquitous at barbecues, beaches, and sporting events due to their practicality in maintaining drink temperature in variable climates. Their popularity stems from a blend of functionality and branding potential, making them a common promotional item across the country.[80] The global can coolers market, encompassing koozies, reached a value of USD 1,860.3 million in 2024 and is projected to expand to USD 1,942.2 million in 2025, with an anticipated compound annual growth rate (CAGR) of 4.4% through 2035, fueled by increasing consumption of canned beers, sodas, and ready-to-drink beverages.[81] This growth is supported by e-commerce platforms, which facilitate easy access to a diverse array of products, including bulk and custom options. Europe represents a significant portion of this market, accounting for about 32% of global share as of 2023 and exhibiting a regional CAGR of 7.5%, driven by the surge in craft beer production and consumption across countries like the UK and Germany.[60][82] Key trends shaping the industry include heightened demand for personalization, with custom koozies featuring monograms, event-specific designs, and branded graphics becoming prevalent for weddings, corporate promotions, and festivals in 2025. In colder climates such as Scandinavia, adaptations like glove-integrated koozies have gained traction, providing insulation for both the drink and the user's hand during winter outdoor gatherings. These developments underscore a shift toward versatile, user-centric products that align with regional preferences and sustainability-focused consumer behaviors.[83][84]References
