The present invention relates generally to beverage containers with an appliqué applied thereto. More specifically, the present invention relates to beverage containers having an edible appliqué applied thereto by a rim attachment or directly to the rim, the appliqué being prepared at a time that is significantly prior to the time of consumption.
Many types of drinks are served in a glass having a rimmer that adds a flavor dimension and/or eye appeal. For example, a margarita is served in a glass having a salt rimmer, a daiquiri is served in a glass having a sugar rimmer, a bloody mary may be served in a glass having a spice rimmer, etc. Rimmers are also considered a way to add flavor to: bellinis, martinis, cosmopolitans, and pina coladas; non-alcoholic cold drinks, such as iced tea, lemonade and milk; and hot drinks such as coffee and cocoa. Typically, the rimmer is prepared on the glass or cup at the location where the drink is served. More specifically, the rimmer is generally applied to the glass when the drink is being mixed and just before it is served. Thus, the rimmer is applied at approximately the time of consumption and is not “pre-applied” to the container.
Traditionally, the margarita-type rimmer is applied by wetting the rim with a lime wedge and immediately placing it in a bed of salt. The wet lime juice provides sufficient adhesion to retain the salt, at least temporarily. Alternately, the rim may be wet with water and then placed in a bed of salt. The salted rim resulting either from lime juice or water wetting of the rim is typically not durable and may fall off as the drink is handled and the juice or water dries. For other drinks, fruit juice or water provides the wetting, and a wide variety of salt, sugar, spice and flavor particle mixes are used for the bed in which the wetted rim is placed.
In a commercial setting, glass rimming adds steps to a drink preparation process that may already be complex. In a busy bar or at hotel receptions and similar functions with large numbers of people to serve, rimming glasses may slow service time unacceptably. Moreover, the materials and equipment used for rimming provide another set of sanitation issues. In a non-commercial setting, rimming glasses is often considered burdensome and overly time-consuming. It is best done with a special tray for holding wetting and rimming material. A host of a party may not rim the glass of each margarita served because of the time associated with setting up the rimming materials and performing the rimming. Further, a sponge is typically used to apply the wetting agent (e.g., juice, water) to the rim of the glass. Such sponge is typically not sanitized over the course of a day (or a party) and microbiological contaminants may become of concern. After several usages, the bed of salt or other rimming material may also be degraded by clumping, and any wetting agent present in the bed may make that material a further possible source of microbiological contaminants.
Plastic cups are not generally considered suitable for rimming. Most plastics used for beverage containers are hydrophobic. Thus, plastic has a low affinity for water, does not wet well, and repels water-based liquids such as lime juice. When lime juice or water is applied to plastic, the liquid forms discontinuous droplets. These droplets retain very little salt when the rim is placed in a bed of salt. Additionally, the dried liquid/salt residue does not typically adhere well to the surface of plastic. One manufacturer has addressed this with a rimming syrup (under the trademark RoxiSpice) which the seller claims “keeps the salt or spice on your plastic glasses for a more attractive presentation.” The rimming syrup and salt or spice are applied approximately at the time of consumption. Listed ingredients for the RoxiSpice product are: high fructose corn syrup, water, propylene glycol, polysorbate 60, xathan gum, malic acid, sodium benzoate, propylene glycol alginate, potassium sorbate.
When a rimmed beverage glass is served, the rimmer is typically functional for flavoring and provides limited eye appeal unless very carefully done. An improved method for providing attractive rimmed beverages would be desirable.
A container rim attachment having a pre-applied appliqué is provided. The rim attachment has a carrier with an outer surface and a rim-receiving recess. There is an attractant appliqué applied to the outer surface of the carrier such that there is an adherence between the appliqué and the outer surface. The adherence between the appliqué and the carrier is sufficient to withstand conditions associated with shipping, storage, or handling of the carrier and appliqué without substantial appliqué degradation.

Overview of Appliqué Placed on Container. A container having a pre-applied edible appliqué is provided. The container, thus, has an appliqué that is applied thereto at a time that is significantly prior to the time of consumption.
a, 1b, and 1c illustrate embodiments wherein the appliqué is pre-applied and bonded to the rim 24 at or around the upper edge of side wall 22 of the container 20. This embodiment may be useful, for example, in the beverage industry. The appliqué 10 may encircle the entire rim 24 or be present on only a portion of it, to offer the user sipping without encountering the appliqué. In alternative embodiments, the appliqué may be applied to other portions of the container in lieu of or in addition to the upper rim 24 of the container 20. As shown in the embodiment of
Containers. As shown in
The container may be formed using any suitable process. For example, the container may be formed by conventional glass, ceramic, plastic, or metal manufacturing methods, with the appliqué added as a food processing step after or during manufacture of the container. The appliqué is added at a time and location other than the time and location of consumption.
The container 20 may be formed of a plastic material (such as polypropylene, polyester, polystyrene, or high density polyethylene). The container 20 may be formed with common processes such as thermoforming or injection molding and configured in any suitable manner. Thus, for example, the container 20 bearing a pre-applied appliqué 10 may be shaped as a margarita glass 20a (shown in
Rim Configurations. The rim of the container 20 may be provided with an enhanced surface area, shape, or volume for receiving the appliqué. As shown in
In
The appliqué 10 may be applied to any surface of the rim structures. Thus, for example, the appliqué may be applied to the top surface and/or the side or bottom surface of the extensions. Referring again to
Bonding. The pre-applied appliqué in one embodiment is used on a disposable container that will be manufactured and then shipped to a point of use. Here the appliqué must be bonded to the rim in such a way that it can survive shipping and handling as well as storage necessary before it is actually used without substantial degradation by loss of rimming material. The bonding should be sufficiently durable to withstand both the handling aspects of shipping, handling, and storage and the time aspects of shipping, handling, and storage (days, weeks or months, typically). The bond must be effective for the appliqué to survive with its food and eye-attractant attributes substantially retained under most shipping and handling conditions with relatively standard forms of packaging and shipping containers as used for disposable or non-disposable beverage containers. Thus, for example, the applied appliqué should be sufficiently durable to provide stability through distribution, ambient condition changes, and exposure to humidity as well as resistance to fracture and erosion when torsion is applied to the containers. One measure of effective bonding is to test the bonding in accordance with ASTM D4169 Standard Test Method for Testing of Shipping Containers and Systems. Using testing as described in the protocol of ASTM D4169, the containers with pre-applied appliqué should be able to withstand shipping conditions without substantial degradation. The bonding should also be suitable for withstanding, for example, end user (server and consumer) handling. Generally, the bond should allow some flexing of the container without significant flaking of the appliqué from the container. Further, the bond preferably does not become tacky in humidity but is not so dry as to flake.
In one embodiment, the appliqué is formed in two parts; an adhesive substrate that will both adhere to plastics (such as a corn syrup and malto-dextrin mixture further described below), and that will also be effective to receive and hold particulate appliqué attractant material (flavoring and/or decorative) applied in a second step, once the adhesive substrate is placed on the container. In another embodiment, the appliqué is a single composition, which contains both the adhesive and the flavoring or decorative material. This material may be either particulate or liquid and substantially homogeneously distributed in a mixture used as the appliqué. In a third embodiment, the appliqué is of a kind that itself can be applied to the container without separate adhesive, e.g., chocolate. Curing may be used to help enhance the bond of appliqué and/or of the appliqué attractant material in any separate adhesive substrate to a container rim. Curing methods depend on the particular materials used (discussed below).
The surface of the container to which the appliqué is applied may further be pre-treated for increasing adhesion of the appliqué. For example, in the embodiment of
While the bond of the appliqué to the adhesive and the adhesive to the container establishes the majority of the desired physical characteristics, for example, that the appliqué and adhesive have some flexibility, be durable, have minimal stickiness, be effectively dried to discourage bio-burden growth, etc., these characteristics may be enhanced or preserved through packaging. For example, moisture barrier packaging may be used to limit exposure of the containers to humidity that may be re-absorbed. Thus, the bond need only withstand humidity that would penetrate moisture barrier packaging. Containers may be individually wrapped or, for greater efficiency in volume use, wrapped in nested stacks. Containers or bags of multiple items may be re-closeable and/or of materials that do not readily adhere to adhesives or appliqués used.
Appliqué Attractant Materials. The appliqué may incorporate any suitable material that makes the container 20 and its contents when filled more attractive. Thus, the appliqué attractant material may impart pleasing sensory qualities, including flavor, texture, mouth feel, smell, and/or color or patterns. Generally, the appliqué is edible. The appliqué may thus impart nutritional, nutraceutical or therapeutic value. The appliqué thus may be a salt, sugar, spice, spice mixture, nut, seed, fruit, vegetable, herb, flower, candy, nutraceutical, vitamin, or medicine. Specific examples include nutmeg, cinnamon, chocolate, pomegranates, olives, mint, coconut, orchids, gardenias, hibiscus, flavored sugar. Further, the appliqué may be provided as finely ground, crushed, chopped, or whole pieces.
In addition to use as a rimmer with food appeal, the appliqué may also be used as a decoration, primarily an eye attractant. For example, the appliqué may be colored or patterned. Thus, for example, containers having appliqués applied thereto, may be mass-produced for sporting events with the appliqués provided in team colors, with or without shapes or patterns, e.g., footballs, hockey pucks.
Placement of Appliqués. As noted above, the appliqué may be applied to the container in any suitable manner such that adhesion or bonding is effective between the appliqué and the container. In one embodiment shown in
Any suitable adhesive may be used but should provide sufficient adhesive properties to impart durability to the bonding of the appliqué to the container. In application of an appliqué to a beverage container or other food container, the adhesive should be edible or be of a material approved for food contact. Suitable adhesives include materials in categories such as starches, gums, sugars, fats, proteins, and pectin. More generally, the adhesive may be any suitable carbohydrate-based, lipid-based, protein-based, or other adhesive. Specific carbohydrate-based examples include maltodextrin, xanthan gum, carboxymethylcellulose, modified starch, and corn syrup. Thus, the adhesive material may be flavor or color neutral (i.e., negligible discernible flavor) or have its own attractant qualities (e.g., vanilla flavor, red coloring) separate from the appliqué attractant material that it holds. The adhesive material may further be selected and configured to complement the taste of the appliqué.
In one embodiment, an adhesive is used that is tacky with a relatively high viscosity, such that the adhesive may be effectively applied to the container and the appliqué attractant material applied to the adhesive before the adhesive can bead up and become discontinuous. The adhesive dries rapidly and retains sufficient tackiness and flexibility to provide durability during shelf-life and transport. For example, such adhesive may be a maltodextrin-corn syrup blend. The blend may range, for example, from approximately 50% malto-dextrin solution and 50% corn syrup, by weight, to approximately 75% malto-dextrin solution and 25% corn syrup, by weight.
If malto-dextrin is used in the adhesive, the malto-dextrin is hydrated to a desired level of viscosity. In one embodiment, the malto-dextrin is hydrated to a viscosity approximately similar to the viscosity of corn syrup. The malto-dextrin may be hydrated with water or may be hydrated with a solution. For example, the malto-dextrin may be hydrated with a solution that imparts a flavor to the malto-dextrin complementary to the appliqué to be applied to the container. Thus, for example, if the adhesive is used for adhering salt to the container, the malto-dextrin may be hydrated with a saturated sodium chloride solution (for example approximately 37.5 grams of sodium chloride per 100 ml water). Further, if the adhesive is used for adhering sugar to the container, the malto-dextrin may be hydrated with a saturated sucrose solution.
The saturated solutions for hydration also serve to help reduce dissolution of a salt, sugar or other water soluble appliqué when the appliqué comes into contact with the adhesive. This may be important to preserve the size of crystalline attractants that provide not only flavor but decorative value and texture. The composition of the adhesive or other applied bonding matrix for holding appliqué material is also selected to preserve color, texture and other attractive qualities of the appliqué material during and after curing. In particular, the formulations discussed above avoid significant degrading of the crystalline attractant appliqués discussed. Unless a particular mixing result on the rim is desired, the adhesive preferably does not affect the integrity of the appliqué material, although there will be several hours or days between preparation of the container with appliqué and its use.
A plasticizer, such as propylene glycol may further be added to the adhesive. An additional ingredient, such as a sugar alcohol, may further be added to reduce water activity and minimize possible microorganism growth.
As stated above, a curing means 420 may be used to cure the adhesive and appliqué. The curing means 420 used may depend on the adhesive and/or appliqué. For example, for chocolate or other fat-based material that is hot applied, cure may be via cooling. Such cooling may be achieved by applying streams of cooled, dry air or by a refrigeration chamber step. Conversely, an adhesive that is cold applied and contains water may be cured via heating. Such heating may comprise a heat-drying process, for example, via placement in a heated oven, passing through a heating unit on a process line, a microwave drying tunnel, or other chamber. Infrared light may also be used for curing. Performing curing rapidly in sequence after adhesive and appliqué are brought together may help retard undesired interactions. Any curing means suitable for the adhesive and appliqué may be used. Generally, the curing means affords curing of the adhesive and/or appliqué without degrading the container.
In other embodiments, the appliqué may be applied directly to the container without a separate adhesive application. This may be done where the appliqué itself is suitable for use as an adhesive. For example, the rim of the container may be dipped in warmed, liquid chocolate and the chocolate allowed to form up. Alternatively, this may be done by mixing an appliqué and adhesive into a homogenous mixture that may be applied to the container. Further, the adhesive may comprise the qualities associated with the appliqué and thus may be used as an appliqué with no further appliqué material being applied. For example, a lemon, lime, mint, licorice, or other flavored adhesive may be applied to the container.
If applied without an adhesive, the appliqué should have sufficient adhesive qualities to impart durability of the application of the appliqué to the container. In the example of chocolate applied to the container, the chocolate may alternately be used as an adhesive for a further appliqué. For example, a crushed candy may be used as an appliqué with the rim of the container being dipped in liquid chocolate and the crushed candy applied to the liquid chocolate. Alternatively, the appliqué attractant material can be formulated as a mixture including one of the adhesive materials mentioned above. This is then applied directly, and cured if necessary.
In a further embodiment, where the container is made of a plastic approved for prolonged food contact, the appliqué may be thermoformed into the plastic material of the container. Then the material of the container effectively serves as the adhesive matrix for the appliqué, such as embedded flavored salt or sugar crystals that have at least a portion of their surface available outside the thermo-formable material to provide flavor or other attractant qualities. Thus, effective bonding may be achieved using the tackiness of hot plastic to secure and/or embed an appliqué into the plastic. In this application localized heating may be applied to soften the thermo-formable material of a rim, with the softened rim then placed in a bed of salt or sugar crystals or other particulate attractant material that is not adversely affected by exposure to the heated thermo-formable material while it cools.
The embodiment of
The appliqué may be applied to the container in any suitable manner. The manner of application may be determined by the desired characteristics of the container. In one embodiment, the appliqué is applied to each container (with or without adhesive) individually. In another embodiment, the appliqué (with or without adhesive) is applied to a nested stack of containers. As seen in
As shown in
The following are a few examples of possible container products with various rim appliqués: disposable margarita cup with lime juice flavored adhesive and sea salt; disposable daiquiri cup with flavorless adhesive and plain or colored sugar crystals; disposable coffee cup with chocolate; disposable hot chocolate cup with mint chocolate; and holiday punch glass with seasonal color pattern in colored adhesive and colored sugar crystals.
Overview of Rim Attachment with Appliqué. In a further embodiment, the appliqué is placed on a container rim attachment to be affixed to a container rim. Thus, only rim attachments with desired appliqués need to be shipped to a bar or other beverage service location and stored there, not entire containers. In addition, a disposable rim attachment may be affixed to a glass, china or other reusable container, resulting in less waste than if an entire container with appliqué were used for each beverage. As seen in

In the embodiment shown in
Where beverage container sizes and lip formations are relatively standard, a bar or other beverage service location will be adequately equipped with a relatively small number of different rim attachments, each with a circumference and rim receiving recess profile that fits one of the standard containers. The containers receiving rim attachments 700 may be made of glass, plastic (including foam), ceramic, paper, metal or other known container materials.
Size Adaptable Rim Attachments. Where container sizes are not standard, the rim attachments may be made adaptable to varying rim circumferences.
In a further embodiment shown in
The rim attachments of the preceding designs may also be formed with colors and with design configurations other than those specifically shown. For example the rim attachments may be formed in colors that match or contrast with the containers or with the appliqué. The rim attachment outer surface 712 (
