Description

BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The invention disclosed herein relates generally to beverage carafes, and more particularly to an improved disposable storage and dispensing carafe which allows the easy storage, transport and dispensing of a bulk volume of a hot or cold beverage in a throw-away container.

[0004] 2. Description of the Background

[0005] Many food product retailers and food service providers offer their customers carry-out hot or cold beverages. The incremental sales of such hot or cold beverages provide a significant profit margin for such product and service suppliers. However, for the consumer purchasing such hot or cold beverages, a significant safety and product quality challenge exists in transporting volumes in excess of what would be consumed by a single consumer. From a safety perspective, while cardboard trays have been provided in the past to help a consumer transport up to four cups containing a hot or cold beverage, the transport of more than four cups is impractical and presents a safety risk of spilling the beverage and even possibly causing burns to the person carrying the beverages. Moreover, from a product quality perspective, the transport of a tray of multiple hot beverage containers is inclined to cool the beverages much more quickly than would a large volume insulated thermos or carafe. Unfortunately, however, the costs of traditional thermoses or carafes makes their sale as a container for a hot or cold beverage sold in a traditional carry-out or catering business setting highly impractical.

[0006] Still further, providing large volume containers for carry-out beverages creates a significant packaging and storage challenge, in that large volume carafes and thermoses take up large amounts of physical space both in shipping vehicles and in storage facilities at retail locations, making their widespread use even more impractical. While nock-down, folded cardboard containers have been used in the past, the use of such a non-rigid material precludes its use for carrying large volumes of a hot or cold beverage (e.g., up to 108 ounces/6 pounds) at one time).

[0007] Thus, there is a need in the art for a disposable storage and dispensing carafe which can safely transport and dispense a bulk volume (preferably at least 108 ounces) of a hot or cold beverage and which may be manufactured at sufficiently low cost to enable the carafe to be disposed of after use, and which is collapsible so as to allow easy transport to and storage at a retail establishment or the like.

SUMMARY OF THE INVENTION

[0008] It is, therefore, an object of the present invention to provide a cost efficient, disposable storage and dispensing carafe which avoids the disadvantages of the prior art.

[0009] It is another object of the present invention to provide a disposable storage and dispensing carafe which enables easy, safe dispensing of the contents of the carafe.

[0010] It is yet another object of the present invention to provide a disposable storage and dispensing carafe having an insulated exterior to maintain the temperature of the carafe contents and to protect persons and objects from inadvertent burns from contacting a stored hot beverage.

[0011] It is still yet another object of the present invention to provide a disposable storage and dispensing carafe having a rigid first means for manually transporting the carafe, and a rigid second means for dispensing the carafe contents.

[0012] It is still even yet another object of the present invention to provide a disposable storage and dispensing carafe having a rigid frame with a readily replaceable fluid content carrier.

[0013] In accordance with the above objects, a disposable storage and dispensing carafe is disclosed which enables the easy transport and dispensing of a large volume (preferably at least 96 to 128 fluid ounces) of a liquid without risk of burn or spillage of the carafe contents. The carafe comprises a rigid, generally rectangular frame having a dispensing outlet at its upper end, an insulated, waterproof, generally pliable or plastic bag for holding the fluid to be dispensed at up to 250° F. and having an opening at its upper end, a rigid spout affixed to the plastic bag at its opening, and means on the rigid spout for attaching the spout to the dispensing outlet of the frame. The frame is also provided a handle having a carrying portion and a dispensing portion. Insulating material preferably in the form of a corrugated paperboard jacket is connected to the frame about the pliable or plastic bag after it is positioned within the frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] As shown in the side view of FIG. 1, the beverage carafe of the instant invention comprises a rigid frame (shown generally at 11) having a support member 12, a spout holder 13 positioned at the top of support member 12, and a handle 14. While handle 14 is denoted in FIG. 1 as a single elongate member, it should be noted that handle 14 particularly comprises a pouring handle member 14a and a carrying handle member 14b, and that such handle members may be provided as distinct rigid members without departing from the spirit and scope of the instant invention. An elongated, generally annular spout 15 having an inlet opening 16 and a dispensing outlet 17 is configured for insertion into spout holder 13. An insulated, waterproof, generally pliable or plastic bag 19 for holding the fluid to be dispensed is connected at its upper end to a heat seal connecting section 18 on spout 15 to form an integral unit therewith. Pliable bag 19 and annular spout 15 are so connected into the supporting assembly 12 of the frame 11 and the spout holder 13 that the dispensing outlet 17 of annular spout 15 will be disposed exterior of frame 11 to enable a cover 20, such as an internally threaded closure cap, to be detachably connected to annular spout 15 about dispensing outlet 17. Insulating material in the form of a jacket 20 is connected to the support assembly 12 about pliable bag 19 and spout holder 13 after the integral spout/bag unit is connected in assembled position on support assembly 12 of frame 11.

[0023] Referring next to the detailed top view, side view, and rear view of the frame of FIGS. 2a, 2b, and 2c, respectively, rigid frame 11 comprises support member 12, spout holder 13 positioned at the top of support member 12, and handle 14. Support member 12 more particularly comprises an internal, rigid, generally rectangular support member 12b circumscribed by an external, rigid, generally rectangular support member 12a. Support members 12a and 12b are interconnected via a planar web 12c extending between outer support member 12a and inner support member 12b, and at their bases via ribs 21. The uppermost section of support members 12a and 12b (as shown in FIG. 2b) may optionally be formed as a concave well extending into the area of the otherwise rectangular forms defined by support members 12a and 12b, but may likewise be formed as a generally horizontal surface, or a convex hump, without departing from the spirit and scope of the instant invention.

[0024] Internal support member 12b is preferably provided with a series of clamping means 25 for holding insulating sleeve 20 on frame 11, as will be discussed in greater detail below. As shown more particularly in the section view of the frame assembly of FIG. 2d, each clamping means 25 preferably comprises a ramp extending outward from the face of support member 12b towards the interior face of support member 12a, and defining a gap 25a between the top of clamping means 25 and the interior face of support member 12a. Likewise, t-shaped tabs 24 are rigidly affixed to the interior of support member 12b and are configured to receive flexible storage bag 19 and hold the same within frame 11, as explained in greater detail below.

[0025] As shown more particularly in FIGS. 2a and 2c, frame 11 is also provided a rigid, ovular, planar base member 12d integrally formed with the other portions of frame 11 and providing a broad, flat base on which the carafe assembly may rest when not in use.

[0026] Rigidly affixed to an upper corner of both support members 12a and 12b is spout holder 13. Spout holder 13 defines a generally annular passage extending from the interior of frame 11 to the exterior of frame 11. The wall of spout holder 13 is preferably segmented at is bottom in order to provide a tab (shown generally at 30) which, due to the inherent flexibility of spout holder 13 (which is preferably formed of polypropylene), may move slightly into and away from the annular passage defined by spout holder 13. The bottom portion of tab 30 is preferably provided a hook 30 for engaging a lip on annular spout 15 to hold annular spout 15 in place within spout holder 13, as will be described in greater detail below.

[0027] Spout holder 13 is also provided a guide flange 31a (FIG. 2a) running parallel to the major axes of spout holder 13 and attached to an interior wall thereof. Guide flange 31a is configured to mate with a guide channel 36 (FIGS. 4a and 4c) on spout 15 so as to ensure proper alignment of spout 15 when it is placed in spout holder 13.

[0028] Handle 14 extends outward from the upper edge of spout holder 13 towards an opposing upper corner of support member 12a where it intersects support member 12a, and down to a location below the midpoint of the rear portion of support member 12a. While the figures depict handle 14 as a generally rounded bar, it should be noted that any similarly configured elongate, rigid structure that intersects spout holder 13 and the top member of support member 12 to provide a handle for vertically transporting the beverage carafe would suffice and not depart from the spirit and scope of the instant invention. Likewise, any similarly configured elongate, rigid handle structure that provides a gripping means along the upper extent of the side member of support member 12 with a lower end attached below the midpoint of the rear portion of support member 12a so as to provide a handle for pouring the contents from the carafe while maintaining balanced control of the its contents would likewise suffice and not depart from the spirit and scope of the instant invention.

[0029] Rigid frame 11 is preferably formed of polypropylene, providing a light-weight structure of sufficient strength and rigidity to be able to support the weight of at least 108 fluid ounces of a beverage (i.e., at least 6 pounds).

[0030] As shown in the perspective view of FIG. 3 and the detailed top, side, and sectional views of FIGS. 4a, 4b, and 4c, respectively, spout 15 comprises an elongated, generally annular shaft having an inlet opening 16 and a dispensing outlet 17, and is configured for insertion into spout holder 13 such that the uppermost portion of spout 15 extends above spout holder 13 when installed. The upper portion of spout 15 is provided with fastening means 32 preferably in the form of external threads circumscribing the outer circumference of the top portion of spout 15, the fastening means being configured to receive and fasten to spout 15 a closure 20 (FIG. 1) on the dispensing outlet 17 of spout 15 to prevent inadvertent spillage during transport. Spout 15 is preferably provided a guide flange 33 running parallel to the major axis of spout 15 along an outer wall thereof, rising in height away from the external surface of spout 15 as it extends down the length of spout 15, and terminating in an abutment 34 formed as a ring circumscribing the exterior of spout 15 near its bottom end. Spout 15 is further preferably provided a guide channel 36 running parallel to the major axis of spout 15 along an outer wall thereof, such guide channel 36 being sized and configured to receive guide flange 31a (FIG. 2a) on spout holder 13 so as to align spout 15 as it is inserted into spout holder 13. When installing spout 15 in spout holder 13, spout 15 is inserted from the bottom portion of spout 15 and is pushed upwards (while being guided and aligned by guide channel 36 and guide flange 31a) until a top abutment 35 comes into contact with an interior ledge on spout holder 13 (not shown). As spout 15 is so inserted, hook 30 on tab 31 of spout holder 13 is guided by guide flange 33 and is thereby flexed outwardly from the center of spout holder 13, until hook 30 overpasses abutment 34 at which point tab 31 snaps back into its original, at-rest position, in turn locking spout 15 in spout holder 13 so as to prevent rearward movement of spout 15 back into the volume of the carafe. Spout 15 is also provided at its bottom with connecting section 18 for heat sealing, adhesively connecting, or otherwise attaching an empty plastic bag 19 thereto, as discussed in greater detail below.

[0031] As shown more particularly in FIG. 5, an insulated, waterproof, generally pliable or plastic bag 19 for holding the fluid to be dispensed is provided which defines an open volume 40 configured to receive a minimum of 108 fluid ounces. Pliable bag 19 comprises two sections of pliable plastic which are heat sealed along two vertical edges, a top edge, and a bottom preferably concave edge which defines a curved bottom to open volume 40, and is preferably comprised of pliable plastic which may withstand temperatures of up to 250° F. without degradation of the bag's integrity. Located between a vertical edge and the top edge of pliable bag 19 is weld spout area 19a which attaches to connecting section 18 on spout 15 to form an integral unit therewith, spout 15 in turn forming a dispensing outlet for the contents of pliable bag 19. As mentioned briefly above, pliable bag 19 and annular spout 15 are so connected into the supporting assembly 12 of the frame 11 and the spout holder 13 that the dispensing outlet 17 of annular spout 15 will be disposed exterior of frame 11 to enable a cover means 20 to be detachably connected to annular spout 15 about dispensing outlet 17. Openings 19b are provided within the heat-sealed region of bag 19, openings 19b being sized to allow the insertion of tabs 24 on support member 12b. When bag 19 is so attached to tabs 24, inadvertent movement of the bag with respect to the interior of frame 11 is largely diminished.

[0032] As shown in the right side and left side views of FIGS. 6a and 6b, respectively, jacket 20 comprises two planar sheets of insulating material configured to be attached to support assembly 12 about pliable bag 19 and spout holder 13 after the integral spout/bag unit is connected in assembled position on support assembly 12 of frame 11. FIGS. 6a and 6b are mirror images of one another, FIG. 6a depicting a side panel for the right side of the carafe, and FIG. 6b depicting a side panel for the left side of the carafe. Each side panel of jacket 20 has generally flat bottom, front, and rear edges. Both the front and rear edges of each side panel are provided with fold lines 51 to facilitate insertion of the front and rear edges of each side panel into clamping means 25 on frame 11. Although not particularly shown in FIGS. 6a and 6b, additional fold or score lines may be provided between the front and rear edges of each side panel in order to more easily enable side panels of jacket 20 to form curved exterior side walls for the carafe body.

[0033] Each of the side panels is also provide a series of perforated tabs 52 positioned adjacent the front and rear edges of each side panel. Perforated tabs 52 are spaced apart from one another the same distance as their corresponding ramps 25 on frame support member 12b, such that when each side panel edge is inserted into the gap 25a between ramps 25 and outer support member 12a and pushed towards frame support member 12b, ramps 25 break the perforations on each perforated tab 52. After the perforations are broken, the interior edge of each ramp 25 will engage the leading edge of the opening in the side panels formed from the separated tab 52 so as to prevent the front and rear edges of the side panels from being inadvertently withdrawn from the frame.

[0034] Further, the top edge of each side panel is provided with a curved score line 53 which, when folded, forms a curved plane 60 defining a top edge of jacket 20 and abutting the top edge of frame 11. The upper, front corner of curved plane 60 is provided a cutout 54 enabling the front corner to lie flush against a side portion of spout holder 13. Likewise, the upper, front corner of each side panel is provided a cutout 55 enabling such front corner to lie flush against the bottom portion of spout holder 13.

[0035] Each side panel of jacket 20 is preferably formed of a pliable corrugated material such as single-faced corrugate, 130 lb. cover, enabling the side panels to provide an insulating surface protecting against inadvertent burns that might be caused by contacting pliable bag 19 directly. Moreover, the general planar form of each of the side panels of jacket 20, as well as the minimal thickness profile of rigid frame 11 other than the base, enables multiple, unassembled carafe units of the instant invention to be shipped and stored in a flat, stacked package, while enabling the same to take on a rounded, full-volume, original carafe appearance when assembled.

[0036] Having now fully set forth the preferred embodiments and certain modifications of the concept underlying the present invention, various other embodiments as well as certain variations and modifications of the embodiments herein shown and described will obviously occur to those skilled in the art upon becoming familiar with said underlying concept. It should be understood, therefore, that the invention may be practiced otherwise than as specifically set forth herein.
