A beverage brewing package 10 in accordance with the present disclosure is shown in FIG. 1. Brewing package 10 is configured to store coffee grinds 12 in a filter bag 14 retained in a cup 16 as suggested in FIG. 3. A consumer can brew coffee 11 by placing brewing package 10 in a coffee maker 18 and exposing coffee grinds 12 stored in filler bag 14 to pressurized hot water discharged from hot water source 19 as suggested in FIG. 4. Brewing package 10 can also be used to brew tea or cocoa by storing tea or cocoa grinds in filter bag 14.
Cup 16 is formed to include several teardrop-shaped stacking lugs 161-166 shown, for example, in FIGS. 3 and 18-20. The stacking lugs 161-166 formed in cup 16 that cooperate with a lug-support rim 16R included in a neighboring cup 16′ in a stack 100 of cups 16, 16′ to provide means for maintaining a minimum separation distance DS between stacked cups 16, 16′ as suggested in FIGS. 14-17 so that cups included in a stack 100 of cups that has been shipped to a brewing package assembly factory can be separated easily at that factory to facilitate manufacture and assembly of brewing packages 10.
Cup 16 includes a bowl 20 formed to include an interior region 201 and stacking lugs 161-166, a spout 22 coupled to bowl 20 and formed to include an interior region 221 placed in fluid communication with interior region 201 of bowl 20, and a brim 24 coupled to top edges of bowl 20 and spout 22 and configured to provide an uninterrupted border surrounding top openings into regions 201, 221 as suggested in FIGS. 2, 3, 5, and 6. It is within the scope of the present disclosure to vary the size and shape of spout 22. Brim 24 includes a C-shaped segment 24C coupled to bowl 20 and a U-shaped segment 24U coupled to spout 22 as suggested in FIGS. 3 and 5.
Brewing package 10 includes a grinds carrier 15 comprising a bag-supporting panel 17 coupled to brim 24 of cup 16 and filter bag 14. Filter bag 14 mates with the underside of bag-supporting panel 17 to support filter bag 14 above floor 20F of bowl 20 as suggested in FIG. 2. Bag-supporting panel 17 is made of a metallic foil or a plastics film in illustrative embodiments of the present disclosure. Filter bag 14 is made of a water-permeable filter material and is configured to hold coffee, tea, or cocoa grinds or similar brewable particulates.
A diagrammatic view of a beverage brewing system such as a coffee maker 18 is provided in FIG. 4. Cup 16 of brewing package 10 is placed on a cup support 13 included in coffee maker 18. Pressurized hot water 19 is admitted into filter bag 14 through an inlet cannula 31 that is arranged to pierce a portion of bag-supporting panel 17 located over bowl 20. Brewed coffee 11 is discharged from cup 16 through an outlet cannula 32 arranged to pierce a portion of bag-supporting panel 17 located over spout 22. Brewed coffee 11 is produced by exposing pressurized hot water 19 to coffee grinds 12 carried in filter bag 14. Such brewed coffee 11 flows from interior region 201 of bowl 20 into interior region 221 of spout 22 and then exits brewing package 10 through outlet cannula 32 as suggested in FIG. 4. Cup 16 is not pierced during a coffee brewing cycle carried out using a brewing package 10 in a coffee maker 18.
Bowl 20 of cup 16 is formed to include a floor 20F and a side wall 20S as suggested in FIGS. 2 and 3. Side wall 20S has a somewhat frustoconical shape as suggested in FIGS. 2 and 3 with a narrow end alongside floor 20F and a relatively wider end alongside brim 24. Side wall 20S is coupled to spout 22 and arranged to extend upwardly from a perimeter edge of floor 20F toward brim 24 and cooperates with floor 20F to form interior region 201 of bowl 20 as suggested in FIG. 3.
Side wall 20S of bowl 20 is formed to include a series of upright liquid-flow channels 20C opening into interior region 201 of bowl 20 as suggested in FIGS. 2-4. Side wall 20S includes a generally frustoconical panel 20P extending from floor 20F to brim 24 and a series of circumferentially spaced radially inwardly extending ribs 20R. Each pair of adjacent ribs 20R is formed to define the radially inwardly facing liquid-flow channels 20C therebetween as suggested in FIGS. 3, 5, and 9. The liquid-flow channels 20C cooperate to provide means for allowing flow of pressurized brewed coffee 11 (or other brewed liquid) upwardly along an inner surface of side wall 20S toward outlet cannula 32 as suggested in FIG. 4.
Side wall 20S of bowl 20 is also formed to include a series of circumferentially spaced-apart stacking lugs 161-166 coupled to the generally frustoconical panel 20P as suggested in FIGS. 2, 3, and 5-8. Each pair of adjacent stacking lugs 161-166 is separated by a central included angle A60 of about 60° as suggested in FIG. 5. Cup 16 and its bowl 20 are made using a thermoforming process in accordance with the illustrative embodiments of the present disclosure to facilitate positive formation of ribs 20R and liquid-flow channels 20C and of stacking lugs 161-166 in side wall 20S of bowl 20.
Each stacking lug 161-166 is arranged to extend radially outwardly away from interior region 201 of bowl 20 to provide means for engaging a lug-support rim 16R provided in an upper portion of side wall 20S adjacent to C-shaped portion 24C of brim 24 as suggested in FIGS. 14 and 16. When stacking lugs 161-166 of cup 16 engage the lug-support rim 16R of an underlying cup 16′ as suggested in FIGS. 14-17, then a minimum separation distance DS is maintained between stacked cups 16, 16′ so as to avoid unwanted wedging of one cup in another underlying neighboring cup.
Each stacking lug 161-162 is teardrop-shaped as shown, for example, in FIGS. 3, 6, 14, and 18-20. Each lug 161-166 includes a narrow peak 50, a relatively wider base 52, and side edges 54, 56 diverging from peak 50 to base 52 as suggested in FIG. 18. An endless border 58 extends around peak 50, side edge 54, base 52, and side edge 56 as suggested in FIGS. 18 and 19. Border 58 surrounds an upside-down ice cream cone-shaped protrusion 60 as suggested in FIGS. 6 and 18. Protrusion 60 is bounded by peak 50, side edge 54, base 52, and side edge 52 as suggested in FIG. 18.
Side wall 20S of bowl 20 and its liquid-flow channel 20C and stacking lug 161-166 features are formed using a thermoforming process in accordance with illustrative embodiments of the present disclosure. Such a thermoforming production process causes formation of liquid-flow channels 20C in a lower portion of side wall 20S to keep an open path between side wall 20S and coffee grinds 12 in filter bag 14 and formation of teardrop-shaped stacking lugs 161-166. These features are positively formed in the cup 16 in accordance with the present disclosure. Such geometry changes allow for a relatively lighter cup 16 made using less plastics material.
A cup 16 for use in a beverage brewing package 10 includes a bowl 20 formed to include an interior region 201 as suggested in FIG. 3. In illustrative embodiments, brewing package 10 also includes coffee, tea, or cocoa grinds stored in filter bag 14 retained in interior region 201 of bowl 20.
