FIELD OF THE DISCLOSURE

[0001] The technical field of this disclosure is apparatus for infusing fluids, such as beverages, with flavor from a material that is contained in the apparatus. The technical field of the disclosure relates more specifically to infusers, carriers, tubes, lids, stirrers, and other structures that are used in connection with fluids or beverages. The disclosure also encompasses the ornamental designs of fluid infusing apparatus in several different forms.

BACKGROUND

[0002] The approaches described in this section are approaches that could be pursued, but not necessarily approaches that have been previously conceived or pursued. Therefore, unless otherwise indicated, it should not be assumed that any of the approaches described in this section qualify as prior art merely by virtue of their inclusion in this section.

[0003] Infusing fluids with flavor is inconvenient, messy or difficult using presently available techniques. Making tea, for example, historically has required the use of a cumbersome perforated dev ice, or mesh item, such as a tea bag. One disadvantage of this approach is that aromatic properties of the contents of the bag or device are not easily sensed, using the nose, at the time that the bag or device is used. Another disadvantage is that placing a bag or device into a closed cup is not easy.

[0004] Infusing coffee imposes a separate set of constraints. For example, studies have shown that consumers do not want to drop tea bags into cups of coffee, as the act produces a visceral negative reaction. Therefore, viscous fluids such as syrups typically are used to add flavor to coffee but it is not possible to produce a syrup for every desirable flavor to be infused. Syrups also necessarily include a large sugar component that adds calories to the beverage, which some users seek to avoid. In addition, practical dispensing of viscous liquids usually requires a large vessel with a strong pump; single servings are difficult to accomplish and typically require a messy packet or package.

SUMMARY

[0032] The appended claims may serve as a summary of the invention. DETAILED DESCRIPTION

[0033] In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, that the present invention may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the present invention.

[0034] FIG. 1A is a front elevation view and FIG. IB is a side elevation view of an embodiment of a flavor infusing device. An elongated body comprises an elongated interior cavity, a top opening, a bottom opening, a plurality of slots and a cap. The body may comprise a tube having walls that are relatively thin in comparison to the length and width of the body. The tubular body may be cylindrical, square, rectangular, or have other cross- section shapes including ones that transition, along the length of the body, from one of (cylindrical, square, rectangular, triangular or a variant or blend of these) to another of (cylindrical, square, rectangular, triangular or a variant or blend of these) Embodiments may be implemented as infusers, carriers, tubes, lids, stirrers, and other structures that are used in connection with fluids or beverages, whether hot or cold, as seen in the many examples that are described in other sections and shown in the drawing figures. In the example of FIG. 1A, the cap, which features an upstanding disk in this embodiment, is dimensioned to snugly fit into the top opening of the body to close off the interior cavity. The bottom opening may be beveled or angled to facilitate inserting the body into a corresponding cavity or hole in a lid or top of a beverage cup. Using a cap is not required and in some embodiments, a seal may be used rather than a removable cap. For example, a seal may be applied at a time of manufacture or loading with a material.

[0035] The body has longitudinal dimensions that are compatible with and less than the depth of a cup into which the body is intended to be placed. As an example, in FIG. 1 A, when the body is placed into a cup, all the slots may be within the cup and may be submerged in a fluid or beverage and the bottom angled or beveled end of the device may rest against or near an interior surface of a bottom wall of the cup. An upper portion of the body may have perimeter dimensions that are greater than the remainder of the body, forming a neck, shoulder or other outwardly extending region that may assist in seating or retaining the body in the hole of the lid of the cup, and slightly above a plane of the top surface of the lid. In this manner, when the device is placed into a fluid or beverage in a cup having a lid, the upper portion of the body remains exposed above the lid and the body cannot fully fall into the fluid or liquid. This position also permits the consumer to perceive aromatic qualities of the material in the body, as further described.

[0036] In an embodiment, the interior cavity contains and conceals a mesh or perforated bag, cylinder, or other package that contains a flavor infusing material. Alternatively, the flavor infusing material may be held directly within the interior cavity, with no other bag, cylinder or other package. In either arrangement, when the flavor infusing device is placed in a fluid or beverage, such as within a cup, molecules of the fluid or beverage can pass into the interior cavity of the device and contact or pass over material that is in the interior cavity. Over time, flavor qualities of the material in the interior cavity are imparted to the fluid or beverage. In an embodiment, the material is selected with a grain or particle size that is too large to exit the interior cavity and enter or foul the fluid or beverage, but with sufficiently small size to present a large surface area to the fluid or beverage for rapid infusion. Mixing properties of the material as compared to fluid properties, such as static tension and surface tension, may be traded off as appropriate to yield a useful particle size that results in rapid infusion without fouling the fluid or beverage.

[0037] FIG. 1C is a partial enlarged perspective view of the embodiment of FIG. 1A, FIG. IB illustrating one or more holes 102 in the cap. In an embodiment, these holes permit upward exhaustion of air from within the body of the device when the device is immersed in a fluid or beverage. Further, the holes permit upward exhaustion of aromatic particles, or infused air, when the body is immersed. Consequently, the device permits the user to smell the flavor that is infused, as it is infused.

[0038] FIG. ID is a perspective view of the device of FIG. 1A, FIG. IB, FIG. 1C in a beverage serving system. In an embodiment, a beverage serving system comprises a cup having a flexible ring integrally formed with an outer wall of the cup; a lid adapted to snugly engage with and cover a top opening of the cup, and having at least one cavity in a top surface of the lid; a flavor infusing device comprising an elongated body having perimeter dimensions that fit into or through the ring. FIG. ID illustrates such a system in which the flavor infusing device is snugly retained in the flexible ring, which has been flexed outwardly from the cup to permit the body of the device to be placed in the ring. In this arrangement, the flexible ring gently urges the device downwardly against the outer wall of the cup, retaining the device in place against the cup. In addition, the lid comprises both a consumption hole, located in a perimeter annular ridge of the lid, and a circular hole that is adapted to receive a body of the flavor infusing device. Optionally, the circular hole may be sealed with a removable seal or label, such as a printed label having low-tack pressure sensitive adhesive. The circular hole may be positioned in the lid in a spaced apart relationship to the consumption hole.

[0039] FIG. ID may represent, in various embodiments, the configuration of a system at the time that a beverage is served to a customer, in which the cup contains a fluid or beverage, or the configuration of the system at the time of shipment from a maker to a vendor or retailer, in which the cup is empty. Alternatively, the flavor infusing device may be shipped or supplied separately to a customer, vendor or retailer.

[0040] FIG. IE is a perspective view of the system of FIG. ID in which the flavor infusing device has been removed from the ring and placed into the cup through a hole in the lid. In this arrangement, the cap of the device protrudes from the hole. Further, when the cup lid is raised to the mouth of the consumer, so that the consumption hole is positioned at the mouth, the holes 102 in the cap will be positioned near the nostrils of the consumer. Consequently, aromatic features of the material in the flavor infusing device and/or aromatically infused air will be readily absorbed into the nasal passages of the consumer and therefore enjoyed.

[0041] Examples of flavor infusing materials that may be used in any embodiments of this disclosure include teas, spices, nuts whether whole, ground, or chopped, coffees, chicory, sugars, crystallized substances such as honey or citrus, dried fruit, dried vegetables or other plant material, and in general any edible material that may impart flavor to a fluid or beverage, hot or cold, when introduced into that fluid or beverage.

[0058] FIG. 13 is a four-part perspective view of a beverage serving system comprising a cup, lid, and flavor infusing device, in one embodiment. As seen in view (A), in an embodiment, a cup containing a beverage or fluid may comprise a lid that is snugly fitted to a top opening of the cup and comprises a consumption hole or slot and an upstanding flavor infuser cover having a hole that may be sealed with a seal. As seen in the partial cross section of view (C), the seal may be removably joined to a flavor infusing bag or capsule that is initially retained above the fluid or beverage within the upstanding flavor infuser cover. As seen in view (B), a consumer may initiate infusing flavor to the beverage or fluid by removing the seal. In response, as seen in view (D), the flavor infusing bag or capsule is released and drops downward. At this point, the flavor infusing bag or capsule contacts or enters the fluid or beverage and an infusing effect may occur as the fluid or beverage enters perforations or holes in the bag or capsule and imparts flavor to the fluid or beverage.

[0059] FIG. 14 A, FIG. 14B are perspective views of an embodiment of a lid having a rotatable flavor infusing device. In this embodiment, a rotating upstanding knob is recessed in a corresponding cavity in the lid. The knob is joined to or integrally formed with a cylindrical body that contains a flavor infusing material and is partly perforated. The perforations are arranged in vertical rows around a circumference of an outer wall of the tubular body, which may be cylindrical, square, or variable in cross section from round to square, round to rectangular, and so forth. The body has a planar circular bottom wall that contains the material within the body. The cylindrical body fits within and can rotate within a slightly larger cylindrical or frustoconical basket having a plurality of vertical slots or channels spaced apart around the circumference of the basket. In this arrangement, rotating the knob causes the body to rotate with the knob, thereby selectively exposing the perforations through the slots of the basket. When the perforations are exposed, the fluid or beverage in a cup to which the lid is attached may be infused with flavor from the material, as the exposed position permits the fluid or beverage to permeate the basket and the cylindrical body to contact the flavor infusing material within the body. The infusion process may be reduced or stopped by again rotating the handle to conceal the perforations of the body so that they are not exposed via the slots.

[0060] FIG. 15 A is an exploded perspective view of a cap and a lid comprising a downwardly extending infusing body. In this embodiment, a cup lid is integrally formed with or attached to the downwardly extending infusing body, which contains a solid infusing material and has a perforated bottom wall. A removable cap may be installed over a top opening in the lid after the solid material has been loaded into the infusing body.

[0061] FIG. 15B is a perspective view of an embodiment of a lid for a cup that comprises an elongated downwardly extending flavor infusing body. In this embodiment, a cup lid is integrally formed with or attached to the downwardly extending infusing body, which contains a solid infusing material and has a perforated bottom wall. A removable cap may be installed over a top opening in the lid after the solid material has been loaded into the infusing body. The embodiment of FIG. 15B is mechanically and functionally similar to the embodiment of FIG. 15 A, except that the infusing body is elongated more greatly and has a narrower diameter. FIG. 15C is a higher angle perspective view of the embodiment of FIG. 15B, showing a cap comprising a plurality of arcuate slots, and showing a set of partial perforations in the downwardly extending body. In various embodiments, the flavor infusing body may be affixed to the cap in a central position that is centered below the cap and centered with respect to a center point of a circle defining a circumference of the lid, or offset radially from the center.

[0062] FIG. 16A, FIG. 16B are perspective views of an embodiment in non-dispensed and dispensed positions. As seen in FIG. 16A, in an embodiment, a cup containing a beverage or fluid may comprise a lid that is snugly fitted to a top opening of the cup and comprises a consumption hole or slot and an upstanding flavor infuser cover having a hole that may be sealed with a seal. The lid may comprise an upstanding perimeter wall that is joined to an interior ring and to the flavor infuser cover. The seal may be removably joined to a flavor infusing capsule or body that is initially retained above the fluid or beverage within the upstanding flavor infuser cover. Retention may be accomplished using an expandable and collapsible bellows structure that is initially collapsed in the position of FIG. 16A and then expanded to permit the capsule or body to enter the fluid in the position of FIG. 16B.

[0063] In this position, a consumer may initiate infusing flavor to the beverage or fluid by pressing downward on the center portion of the lid or upon the seal. In response, the flavor infusing capsule or body is urged downward, while remaining attached to the lid, thereby rapidly expanding the bellows structure and adopting an expanded position. In some embodiments, a snapping sound may accompany this downward expansive motion. At this point, the flavor infusing capsule or body contacts or enters the fluid or beverage and an infusing effect may occur as the fluid or beverage enters perforations or holes in the bag or capsule and imparts flavor to the fluid or beverage. FIG. 16B illustrates the resulting position in which the capsule or body has popped downward via mechanical action.

[0064] FIG. 17 A, FIG. 17B, FIG. 17C illustrate embodiments of a flavor infusing device comprising a top disc, a shaft, and a perforated body. The shaft is elongated and may be solid. The shaft has a first end that is joined to or integrally formed with the top disc and a second end that is joined to or integrally formed with a top solid generally planar wall of the perforated body. The perforated body may be constructed as a thick perforated disc, as seen in FIG. 17A, in which the body comprises two circular front and rear walls that are perforated, joined by or integrally formed with a circumferential side wall. Or, as seen in FIG. 17B, the body may comprise an elongated cone having an apex that is integrally formed with and tapered into the shaft. A bottom end of the cone may be closed by a hemispherical bottom wall that is imperforate. All or a portion of the cone may be perforated or may comprise mesh walls.

[0065] FIG. 17C illustrates an embodiment in which the shaft is relatively short as compared to the body, which may comprise a perforated tapered cylinder having a round bottom wall with a diameter that is less than that of an upper portion of the body. All or a part of the circumferential outer wall of the body may be perforated.

[0066] FIG. 18 A, FIG. 18B are partial perspective views of an upper portion of a flavor infusing device showing details of one embodiment of a cap and cap securing apparatus. In an embodiment, a flavor infusing device comprises an elongated tapered partly perforated body having a flared upper end with a circular upper opening. A cap comprises a circular top wall joined to or integrally formed with a circumferential side wall. Dimensions are not critical but the vertical height of the side wall typically is less than one diameter of the circular top wall. In an embodiment, the cap comprises two or more outwardly protruding bosses 1802. An inside wall of the top operation of the device comprises two or more slots 1806 or elongated recesses that are arranged longitudinally, and two or more holes 1804 that are spaced apart from a top edge of the circular upper opening. In this arrangement, assembly of the cap to the body may comprise placing the bosses 1802 in the slots 1806 and guiding or pressing the cap downward into the body until the bosses meet and snugly engage the holes 1804. This process results in a cap that is snugly retained in the upper opening of the body, closing off the opening and preventing solid material in the body from spilling out the upper opening if the body is inverted or turned.

[0067] Optionally, the cap may include one or more slots, holes, removable elements, or other openings that permit the consumer to sense aromatic qualities of solid material in the body. FIG. 19A, FIG. 19B are perspective views of a flavor infusing device similar to that of FIG. 18A, FIG. 18B illustrating an alternative cap embodiment, in which the cap comprises a plurality of arcuate slots extending partly around regions of a perimeter of the circular top wall of the cap. FIG. 19A is an exploded view showing that the cap may be initially manufactured as a separate element and then press fit or otherwise snugly joined to the body. FIG. 19B illustrates the same elements in which the cap is installed in a recessed position within the body.

[0068] The embodiments described herein may be manufactured using a variety of materials and processes. In some embodiments, the flavor infusing device is made from a food-grade plastic. Examples may include any of several polyethylenes (PET, HDPE, LDPE), natural polylactic acids, polypropylene, and so forth. Cups may be paper, plastics, ceramics or non-reactive metals such as aluminum. Lids may be plastics as set forth above, ceramics or non-reactive metals. Caps for flavor infusing devices may be any of the plastics noted above as well as polystyrenes. Seals may be paper with self-adhesive gum, plastics, polystyrene, nylon, etc. Perforation diameters are not critical and could be about 1mm, for example.
