Description

DETAILED DESCRIPTION OF THE DISCLOSURE

[0019] Certain terminology is used in the following description for convenience only and is not limiting. The words lower, bottom, upper, and top designate directions in the drawings to which reference is made. The words inwardly, outwardly, upwardly and downwardly refer to directions toward and away from, respectively, the geometric center of the device, and designated parts thereof, in accordance with the present disclosure. Unless specifically set forth herein, the terms a, an and the are not limited to one element, but instead should be read as meaning at least one. The terminology includes the words noted above, derivatives thereof and words of similar import.

[0020] Referring to the drawings in detail, wherein like numerals indicate like elements throughout, FIGS. 1-12 illustrate an apparatus for brewing beverages, namely a tea kettle, in accordance with a preferred embodiment of the present disclosure. The tea kettle herein shown and described is an electric tea kettle, in that it would have an electrically-powered internal heat source (not illustrated). However, an apparatus for brewing beverages of embodiments of the present disclosure may be a non-electric tea kettle that is heated with an external heat source. Further, an apparatus for brewing beverages of embodiments of the present disclosure may be a beverage brewing apparatus other than a tea kettle.

[0021] The tea kettle 10 has a container portion 12 which defines a reservoir for receiving water to be heated and for receiving an infusible foodstuff for brewing a beverage, a base portion 14 containing a heating element (not illustrated) for heating water in the reservoir, an on/off switch 16 (or other suitable user interface) for controlling the operation of the tea kettle, a handle 18, a pour spout 20, and an open top end with a lid 22 that is removably mountable to the container portion 12 to selectively close off the top end. The lid 22 may have a lower skirt portion 28 that fits relatively snugly within the top end of the container portion 12. The lid 22 also may have one or more outwardly biased protrusions 30 that engage with the inside surface of the top end of the container portion to help retain the lid 22 in place on the top end.

[0022] The tea kettle 10 further has a steeping basket 32 that is suspended within the reservoir (when the lid is in place on the top end) via an elongated rod 34. The steeping basket 32 is selectively insertable into the reservoir through the open top end. The steeping basket 32 comprises a lid 36 that is attached to the lower end 50 of the rod 34 and a main body 38 that is selectively attachable to and separable from the lid 36. The main body 38 has a cylindrical wall (although other shapes may be used) in which a plurality of holes 40 are defined and a floor (which may or may not have holes) (not illustrated). The lid 36 and main body 38 of the steeping basket 32 define a chamber for receiving an infusible foodstuff such as tea leaves. The main body 38 separates from the lid 36 (via, for example, cooperating threads on the main body 38 and the lid 36) to add the infusible foodstuff into the chamber and then reattaches for brewing. The holes 40 allow water in the reservoir to enter the steeping basket 32 and contact the infusible foodstuff within the chamber.

[0023] The rod 34 is selectively insertable through a through-hole 94 of the lid 22, with the rod 34 and lid 22 being slidingly movable relative to each other when so inserted. The upper end 52 of the rod 34 is selectively attachable to and separable from a grasping portion 24 (described further below). When (i) the grasping portion 24 is attached to the rod 34, (ii) the steeping basket 32 is in the reservoir, and (iii) the lid 22 is closing off the open end, a user may move the grasping portion 24 up and down to correspondingly move the steeping basket 32 up and down within the reservoir. The steeping basket 32 is typically placed in the up or raised position (shown in FIG. 2) while the water in the reservoir is heated, and then the steeping basket 32 is lowered into a down or steeping position (shown in FIG. 1) to steep the tea leaves in the steeping basket 32. The steeping basket 32 is then typically raised again after the desired amount of steeping time. A circumferential channel 42 or similar indentation is defined in the rod 34 near the lower end 50. The channel 42 engages with one or more spring-loaded catches 96 (three are illustrated in FIG. 12) within a cavity 90 in the lid when the steeping basket 32 is raised up to help prevent sliding movement of the rod 34 which in turn helps retain the steeping basket 32 in the raised position. In the illustrated embodiment, the catches 96 each comprise a ball bearing 98 that partially protrudes from a housing and that is biased toward the rod 34 by a spring 100.

[0024] FIGS. 3 and 4 illustrate the lid 22, steeping basket 32, and grasping portion 24 in an attached arrangement and removed from the container portion 12 for, e.g., filling the basket with tea leaves or for cleaning. As discussed above, the awkwardly-shaped structure of the attached arrangement shown in FIGS. 3 and 4 may be difficult to clean as it may not fit well and/or sit stably on a dishwasher rack for cleaning. As such, the grasping portion 24 comprises at least one release actuator which, when actuated, enables the grasping portion to be separated from the upper end of the rod. In the illustrated embodiment, the grasping portion 24 comprises two opposing release actuators 26a, 26b which, when pushed inwardly (i.e., toward the centerline of the tea kettle, as indicated by arrows 84 in FIGS. 7 and 11) enables the grasping portion 24 to be separated from the upper end 52 of the rod 34. The grasping portion comprises a main body 62, a cover 60 concealing a hollow space in which internal components are located (as seen in FIGS. 7-9), and a downwardly protruding portion 64. A hole 65 is defined in the downwardly protruding portion 64 for receiving the upper end 52 of the rod 34 to enable the engagement of the rod 34 and the grasping portion 24. One or more tabs (two opposing ones 63a, 63b are shown in FIG. 6) protrude from the downwardly protruding portion 64 to selectively engage with one or more corresponding slots 92 (two opposing ones are shown in FIG. 12) in a twist-lock manner to selectively lock the lid 22 and grasping portion 24 together.

[0025] As seen in FIGS. 7-11, the release actuators 26a, 26b each have an elongated body that is contained within the main body 62 of the grasping portion 24 and normally hidden by the cover 60. A spring 68 biases the release actuators 26a, 26b outward (i.e., radially away from the centerline of the tea kettle). The elongated bodies of the release actuators 26a, 26b each terminate in a sloped edge 70, 72. A wedge 66 is located between the sloped edges 70, 72 of the release actuators 26a, 26b. The wedge 66 is upwardly biased by spring 76. The wedge 66 has opposing upper sloped sides 80 which slope (top-to-bottom) away from the midline of the wedge 66 and opposing lower sloped sides 82 which slope (top-to-bottom) toward the midline of the wedge 66.

[0026] The grasping portion further comprises an engagement member 74 that has two free ends positioned on opposing sides of the hole 65 and adjacent to the opposing lower sloped sides 82 of the wedge 66. The engagement member 74 is constructed of a resilient material that causes the free ends to return to their original positions after being pushed apart. An indentation 54 is defined in the rod 34 adjacent the upper end 52 (typically around the entire circumference of the rod 34, as illustrated). The upper end 52 of the rod 34 is typically tapered, as illustrated. When the upper end 52 of the rod 34 is inserted into the hole 65 to attach the rod 34 and the grasping portion 24, the tapered upper end 52 pushes apart the two opposing free ends of the engagement member 74. The rod 34 is advanced until the opposing free ends of the engagement member 74 engage the indentation 54 on opposite sides of the rod 34 as seen in FIG. 9. The resilience of the opposing free ends of the engagement member 74 provide a snug engagement that helps retain the upper end 52 of the rod 34 until released (as described below).

[0027] To separate the grasping portion 24 and the rod 34, the release actuators 26a, 26b are pushed inwardly, as indicated by arrows 84. Each sloped edge 70, 72 of the release actuators 26a, 26b is adjacent to and engages a corresponding one of the opposing upper sloped sides 80 of the wedge 66. When the release actuators 26a, 26b are pushed inwardly, the engagement between the sloped edges 70, 72 of the release actuators 26a, 26b and the upper sloped sides 80 of the wedge 66 cause the wedge 66 to move downward as indicated by arrow 86 in FIG. 11. A lower end of the wedge 66 sits between the opposing free ends of the engagement member 74, as best seen in FIG. 11. As the wedge 66 moves downward, the opposing lower sloped sides 82 engage the opposing free ends of the engagement member 74 and push apart the two opposing free ends of the engagement member 74 as indicated by arrows 88 in FIG. 11. As the opposing free ends of the engagement member 74 are pushed apart, the opposing free ends of the engagement member 74 disengage from the indentation 54 to enable the upper end 52 of the rod 34 to be pulled out of the grasping portion 24 to separate the rod 34 and the grasping portion 24.

[0028] It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof. It is understood, therefore, that this disclosure is not limited to the particular embodiments disclosed, but it is intended to cover modifications within the spirit and scope of the present disclosure as defined by the appended claims.
