Description
BACKGROUND
[0001] The present invention relates to a beverage server.
[0002] Beverage servers are generally known. Such known beverage
servers typically include a base container, a lid, stopper and an
actuator. The base container is typically symmetrical about a
vertical axis and wider at the bottom than at the top. Actuation of
the actuator by the user moves the stopper between an open position
(wherein liquid may be dispensed or poured from the container) and
a closed position (wherein liquid is prevented from being poured
from the container). Actuation of the actuator and/or movement of
the stopper comprises pivoting or rotating movement.
[0003] However, such beverage servers have several disadvantages.
For example, such shape and configuration of the base requires a
substantial tilt angle to dispense liquid. The greater the tilt
angle, the more effort, skill and possibility of leakage or
spillage. Also, pivoting movement of the actuator or the stopper
requires complexity not necessary for a beverage server.
[0004] Accordingly, it would be advantageous to provide a beverage
server. It would also be advantageous to provide a beverage server
with a trigger actuator configured for linear movement and a
stopper configured for linear (horizontal, vertical, and/or
diagonal) movement. It would also be advantageous to provide a
beverage server with a liquid level indicator and an integral
contents indicator. It would also be advantageous to provide a
beverage server that is substantially snap fit together. It would
also be advantageous to provide a beverage server that has a
slanted or offset configuration to improve dispensing without
reducing stability when sitting on a surface. It would be desirable
to provide for a beverage server having one or more of these or
other advantageous features. To provide an inexpensive, reliable,
and widely adaptable beverage server that avoids the
above-referenced and other problems would represent a significant
advance in the art.
SUMMARY
[0005] One embodiment of the invention relates to a beverage server
for containing and dispensing liquid. The beverage server comprises
a base; a stopper coupled to the base and movable in at least a
linear direction between an open position and a closed position; a
handle coupled to the base; and an actuator coupled to the handle
and to the stopper and movable in a linear direction between a
first position and a second position. The linear movement of the
actuator from the first position to the second position moves the
stopper from the closed position to the open position. The lid
includes a surface that engages the stopper and guides the movement
of the stopper. The actuator is moveable by a user squeezing the
handle to apply pressure between the grip and the handle.
[0006] Another embodiment of the invention relates to a beverage
server for containing and dispensing a liquid. The beverage server
comprises a base configured to contain the liquid and including a
top and a bottom; and a pour spout extending from the base and
configured to guide liquid being dispensed from the base. The
bottom of the base is offset from the top of the base in a
direction opposite from the direction of the pour spout. The base
may comprise an outer body, a reservoir located inside the outer
body and coupled to the outer body by a plurality of snap-fit
connections.
[0007] Another embodiment of the invention relates to a beverage
server for use in containing and dispensing a liquid. The beverage
server comprises a base configured to contain liquid; a lid coupled
to the base; a stopper coupled to the lid and movable between an
open position and a closed position; a handle coupled to the base;
an actuator, and a pour spout extending from the base and
configured to guide liquid being dispensed from the base. The
actuator is coupled to the stopper and movable in a linear
direction between a first position and a second position. Linear
movement of the actuator from the first position to the second
position linearly moves the stopper from the closed position to the
open position. The bottom of the base is offset from the top of the
base in a direction opposite from the direction of the pour spout.
The base may comprise a liquid level indicator/window and a
contents indicator/dial.
[0008] The present invention further relates to various features
and combinations of features shown and described in the disclosed
embodiments. Other ways in which the objects and features of the
disclosed embodiments are accomplished will be described in the
following specification or will become apparent to those skilled in
the art after they have read this specification. Such other ways
are deemed to fall within the scope of the disclosed embodiments if

DETAILED DESCRIPTION OF THE PREFERRED AND EXEMPLARY EMBODIMENTS
[0015] Referring to the FIGURES, a beverage server 10 is shown
according to an exemplary embodiment. Beverage server 10 is
configured to substantially contain a liquid and allow the liquid
to be poured out. Beverage server 10 may be configured to have
insulating properties and be configured to insulate the contained
liquid (i.e., keep a beverage at a temperature greater than or less
than room temperature). According to an exemplary embodiment shown
in FIGS. 1 and 2, beverage server comprises a base 12, and a lid 14
coupled to base 12.
[0016] Base 12 forms the main body of beverage server 10 and has a
slanted or offset configuration (e.g., non-concentric about its
axis such that a top portion is not directly above a bottom
portion). Base 12 comprises an outer body 20, a reservoir 30, a
handle 40, a handle cover 50, a sealing member 52, a collar 54, and
an actuator (shown as a trigger 60). Outer body 20 (e.g.,
container, casing, shell, etc.) is a generally thin-walled body
that comprises a side wall 22 and an end plate 24 and has a
generally open top (prior to attachment of handle 40). Side wall 22
may have a cross-section that is circular, non-circular,
elliptical, tapering, tubular, or the like. According to an
exemplary embodiment, side wall 22 and end plate 24 are separate
bodies. According to other exemplary embodiments, side wall 22 and
end plate 24 may be formed as a single unitary body.
[0017] Reservoir 30 (e.g., bladder, inner body, liner, etc.) is a
generally thin-walled body that is configured to contain a liquid
and is housed within outer body 20. Reservoir 30 may have a
cross-section that is circular, non-circular, elliptical, tapering,
tubular, or the like. As shown, reservoir 30 contains a single
liquid (e.g., coffee), but could be modified to provide two or more
spaces to contain multiple different liquids (e.g., regular coffee,
decaffeinated coffee, cream, water, tea, etc.). Outer body 20 and
reservoir 30 may be separated by a space 26. Space 26 (e.g., gap,
separation, void, etc.) is configured to inhibit heat transfer
between outer body 20 and reservoir 30 (e.g., insulate reservoir
30). According to various exemplary embodiments, the space may be
filled with a gas (e.g., air), a solid (e.g., polyurethane foam),
or a vacuum. Reservoir 30 comprises a generally cylindrical outlet
32 (e.g., neck, opening, passage, narrow portion, etc.) along the
top that is configured to direct a liquid inside reservoir to lid
14 so that is can be poured. Outlet 32 comprises threads 34 and a
flange 36 that is configured to receive a sealing member 52, shown
as an o-ring.
[0018] Referring especially to FIGS. 2-4, the top and bottom ends
of base 12 (and reservoir 30) are offset such that the top of
reservoir 30 is slanted or tilted forward relative to the bottom.
The offset nature of reservoir 30 allows a user to tip beverage
server 10 less of an angle to pour a liquid from beverage server 10
than would be needed if the side walls of reservoir 30 were
substantially vertical.
[0019] Handle 40 is provided to allow a user to lift and manipulate
beverage server 10. According to an exemplary embodiment, handle 40
is threadably coupled to the top of base 12 and comprises a body
portion 42 and a grip portion 44. Body portion 42 at least
partially surrounds lid 14 and may be configured to present a
substantially continuous out surface with base 12. Grip portion 44
extends outward from the rear of base 12. Grip portion 44 is a
generally hollow body with an aperture 46 (e.g., open side,
opening, etc.) facing towards outer body 20 that receives trigger
60 and allows trigger 60 to slide in grip portion 44. Grip portion
44 receives a handle cover 50 that is contoured to substantially
match the contour of grip portion 44, cover the hollow body of grip
portion 44, and present a generally smooth surface when coupled to
grip portion 44. The handle and/or handle cover may include a
plurality or holes or openings that facilitate the draining and/or
evaporation of any water inside the handle (e.g., if the server has
been submerged in water).
[0020] According to an exemplary embodiment, base 12 further
includes a fluid level indicator 56 (e.g., window, gauge, meter,
etc.) that is configured to allow a user to visually determine the
level of the liquid in reservoir 30 without opening beverage server
10. According to an exemplary embodiment, outer body 20 includes an
aperture 28 (opening, slot, etc.) that receives a protruding
portion 38 of reservoir 30. Protruding portion 38 may partially or
completely extend through aperture 28. Reservoir 30 may be made
entirely of a substantially transparent material (e.g. an acrylic
resin) or may only include a protruding portion 30 that is
substantially clear. According to an exemplary embodiment,
indicator 56 is located on the front of server 10, generally
opposite of handle 40. According to other exemplary embodiments,
indicator 56 may be proximate to handle 40 or may be on the side of
server 10.
[0021] A collar 54 is provided that is threadably coupled to
reservoir 30. As collar 54 is threaded onto reservoir 30, body
portion 42 of handle 40 is trapped between collar 54 and flange 36
on outlet 32, compressing sealing member 52. Collar 54 has an inner
diameter that is substantially the same as the inner diameter of
outlet 32 to provide a generally smooth and continuous surface to
receive lid 14.
[0022] Trigger 60 is configured to slide generally horizontally
between a first (e.g., closed, disengaged, rest, extended, etc.)
position and a second (e.g., open, engaged, use, retracted, etc.)
position. Trigger comprises a grip portion 62 (portion that user
interfaces with), a connecting portion 64, an engaging portion 66
and a stop 68. Interface 62 is a surface that is configured to be
engaged by the inside portion of a user's fingers when the user is
grasping handle 40. When the user squeezes or pulls back on trigger
60, trigger 60 slides within handle 40. Connecting portion 64
couples interface 62 to engaging portion 66 and is configured to
add rigidity to trigger 60. Engaging portion 66, shown as a
generally vertical wall or tab (e.g., hook), is configured to
engage a feature in stopper 80 (shown as slot 89 and further
described below). Stop 68, shown as a vertical member wall
extending downward from connecting portion 64, is configured to
contact a corresponding wall 48 (e.g., ledge, ridge, stop, etc.) to
limit and guide the horizontal travel of trigger 60.
[0023] Lid 14 is coupled to the top of base 12 and is configured to
controllably allow release a liquid from inside reservoir 30.
According to an exemplary embodiment, lid 14 is coupled to base 12.
Referring to FIGS. 2 and 3, lid 14 is captured within body portion
42 by a molded-in catch feature at the rear of spout cover 94a that
engages a lip on the front edge 87 of handle cover 50. As such,
rather than being screwed on or hinged on, lid 14 may be removed or
separated from body 42 by releasing catch 85 (e.g., by pushing in
the in-molded catch 85). Alternatively, the lid may be coupled to
the base by a variety of techniques. According to an exemplary
embodiment, lid 14 comprises a spout 70, a sealing member 90, a
stopper 80, a biasing member 92, a spout cover 94, and a contents
indicator 96 and dial 98.
[0024] Spout 70 urges liquid emerging from inside reservoir 30 into
a narrow stream, allowing a user to pour the liquid into a
receptacle while reducing the chance of the liquid spilling outside
the receptacle. Spout 70 comprises a generally cylindrical neck 72
which extends downward from spout 70 and is configured to be
received by outlet 32 of reservoir 30. A lip 74 (e.g., ledge,
protrusion, ridge, etc.) extends outward from the end of neck 72.
Sealing member 90 is a generally ring-shaped body that comprises a
groove 91 (e.g., depression, channel, etc.) along its inner
surface. Groove 91 is configured to receive lip 74 and
substantially couple sealing member 90 to spout 70. Sealing member
90 frictionally couples spout 70 to reservoir 30 when neck 72 is
inserted into outlet 32.
[0025] Spout 70 further comprises a wall 76 and an opening 78. Wall
76 extends upward from spout 70 and acts a stop to limit the
horizontal travel of trigger 60. Opening 78 (e.g., aperture,
cutout, track, etc.) allows engaging portion 66 of trigger 60 to
pass through spout 70 and slide between the first position and the
second position.
[0026] Stopper 80 (e.g., closure element, gate, flap, etc.) is a
member that is coupled to trigger 60 and is configured to
substantially retain a liquid in reservoir 30 when in a closed
position. Stopper 80 and trigger 60 are substantially prevented
from moving in the vertical direction and allowed limited movement
in the horizontal direction (e.g., from front to back) between a
first or closed position and a second or open position. Stopper 80
comprises a generally planar lid portion 81, a first vertical
portion 82, a first horizontal portion 84, a second vertical
portion 86, and a second horizontal portion 88 lid portion 81 is
configured to contact spout 70 when stopper 80 is in a closed
position and substantially retain a liquid in reservoir and to
allow a liquid to escape reservoir 30 when stopper 80 is in an open
position. First vertical portion 82 (e.g., forward wall), first
horizontal portion 84 (e.g., slide, bearing surface, etc.), and
second vertical portion 86 (e.g., rear wall) form a generally
u-shaped structure. First horizontal portion 84 slides along the
top edge of wall 76 of spout 70 as trigger 60 is moved from the
first or closed position to the second or open position. First
vertical portion 82 and second vertical portion 86 are configured
to limit the movement of trigger 60 by contacting wall 76 generally
corresponding to the open and closed positions, respectfully.
Second horizontal portion 88 extends outward from second vertical
portion and includes a slot 89 (e.g., slit, aperture, opening,
etc.) that is configured to receive engaging portion 66 of trigger
60 and substantially couples stopper 80 to trigger 60.
[0027] Biasing member 92 may be provided to urge stopper 80 towards
the closed position when a user is not engaging trigger 60.
According to an exemplary embodiment, biasing member 92 is a coil
spring that is coupled between stopper 80 and spout cover 94.
According to one exemplary embodiment and as shown in FIGS. 3 and
4, a biasing member, shown as coil spring 58, may be disposed
between trigger 62 and handle 50. According to another exemplary
embodiment (as shown in FIG. 6) the biasing member may be a leaf
spring 158. According to still other exemplary embodiments, trigger
62 or handle cover 50 may include an integrally formed resilient
portion that is configured to bias trigger 62 away from handle
50.
[0028] Spout cover 94 is configured to substantially enclose
stopper 80. Spout cover 94 generally follows the contour of body
portion 42 of handle 40 and comprises an open end 95 and a
plurality of indicators 96 integral with cover 94. Open end 95 is
aligned with the end of beverage server 10 opposite of grip portion
44 and allows a liquid to be poured out of reservoir 30. Indicators
96, shown arranged generally radially, cooperate with a dial 98
coupled to spout cover 94. Indicators 96 are selectively revealed
by dial 98 to allow a user to determine the type of liquid
contained in beverage server 10. According to one exemplary
embodiment, indicators 96 are arranged radially. According to other
exemplary embodiments, indicators 96 may be in another arrangement
(e.g., linearly, parallel, etc.) such that they can be selectively
revealed by dial 98.
[0029] Drainage passages are provided by holes or openings 45 and
65 (e.g., drain holes, "weep" holes, etc.) on handle 40 and trigger
60 respectively. In the event that liquid enters the interior of
the handle (e.g., from the area between handle 40 and trigger 60
when beverage server 10 is being washed into the area between
handle 40 and trigger 60. Weep holes 65 provide a first drainage
passage that allows water to drain if server 10 is dried orientated
in an upright orientation and weep holes 45 allow water to drain if
server 10 is dried orientated in an upside down or inverted
position. According to other exemplary embodiments, weep holes 45
and 65 may be a variety of shapes and may be provided in a variety
of locations. According to alternative embodiments, additional
holes may be provided as desired and as the internal structure

to controllably allow release a liquid from inside reservoir 130.
According to an exemplary embodiment, lid 114 comprises a spout
170, a sealing member 190, a stopper 180, a biasing member 192, a
spout cover 194, and a dial 198.
[0034] Spout 170 guides urges liquid emerging from inside reservoir
130 into a narrow stream, allowing a user to pour the liquid into a
receptacle while reducing the chance of the liquid spilling outside
the receptacle. Spout 170 comprises a generally cylindrical neck
172 that extends downward from spout 170 and is configured to be
received by outlet 132 of reservoir 130. Sealing member 190 is a
generally ring-shaped body that comprises a horizontal portion and
a vertical portion and is trapped between handle 140 and reservoir
130. Sealing member 190 frictionally couples spout 170 to reservoir
130 when neck 172 is inserted into outlet 132. Sealing member 190
substantially seals the interface between spout 170 and reservoir
130 and helps reduce the chance of any liquid escaping into the
space between reservoir 130 and outer body 120. Spout 170 further
comprises a slanted or inclined surface 177. Inclined surface 177
extends backward from neck 172 and provides a bearing surface for
stopper 180.
[0035] Stopper 180 (e.g., closure element, gate, flap, etc.) is a
member that is coupled to trigger 160 and is configured to
substantially retain a liquid in reservoir 130 when in a closed
position (i.e., prevent or inhibit liquid from being poured out of
reservoir 130). Stopper 180 is allowed limited movement in the
horizontal direction (e.g., from front to back) and in the vertical
direction (e.g., up and down) between a first or closed position
and a second or open position. At portions of its movement, Stopper
180 has both horizontal and vertical movement (i.e., diagonal or
angular movement). Stopper 180 comprises a generally planar lid
portion 181, a first vertical portion 182, a second vertical
portion 186, and an inclined surface 188. First vertical portion
182 (e.g., forward wall) is coupled to a biasing member, shown as a
spring 192. When stopper 180 is moved from a closed position to an
open position, engaging portion 166 of trigger 160 contacts second
vertical portion 186 and pulls stopper into the open position.
Inclined surface 188 contacts inclined surface 177 on spout 170 and
provides guided diagonal or angular linear movement (i.e., movement
that is both horizontal and vertical movement). As stopper 180
moves to an open position, inclined surfaces 188 and 177 interface
to force stopper to move upward, creating a larger opening for
liquid escaping from reservoir 130.
[0036] Spring 192 is preferably provided to urge stopper 180
towards the closed position when a user is not engaging trigger
160. According to an exemplary embodiment, spring 192 is a coil
spring that is coupled between first vertical portion 182 of
stopper 180 and spout cover 194. According to other exemplary
embodiments, the spring may be provided between stopper or trigger
and any component that they move relative to when a user engages
the trigger. Alternatively, the spring may be a leaf spring or any
of a variety of biasing members (e.g., integrally molded as a
plastic projection extending from the stopper or other portion of
the lid).
[0037] Due to the non-concentric shape, the assembly of the server
generally comprises building the server from the bottom up using
several snap fit connections. For example, the server 110 is
assembled by first locating reservoir 130 in bottom 124 with dimple
137. Reservoir 130 is snapped (clipped) or otherwise coupled to
bottom 124. A generally cylindrical side wall 122 is fitted over
reservoir 130 and a protruding portion 138 of reservoir 130 is
aligned with a corresponding opening 128 in side wall 122 to form a
level indicator 156. A space 126 is left between reservoir 130 and
side wall 122 to help insulate reservoir 130. According to various
exemplary embodiments, the space may be filled with a gas (e.g.,
air), a solid (e.g., polyurethane foam), or a vacuum. Gasket 190 is
fitted onto outlet 132 and trapped between handle 140 and reservoir
130. Handle 140 is coupled to reservoir with a snap fit engagement
and a fastener (shown as a tab 147 and a screw 149). Trigger 160 is
inserted into handle 140 and allowed to extend through an opening
146 in the grip portion 144 of handle 140. Handle cover 150 is
coupled to handle 140 (e.g., interference fit, a snap fit
engagement, heat staking, ultrasonic welding, fastener, etc.).
Spout 170 is frictionally coupled to reservoir 130 by gasket 190
and the engaging portion 166 of trigger 160 is allowed to pass
through an opening in inclined surface 177. Stopper 180 is coupled
to spout cover 194. Lid 14 is coupled to handle 140 such that the
open end 195 of spout cover 194 is aligned with the front of
beverage server 110 and stopper 180 engages trigger 160.
[0038] Server 110 is used by gripping selectively handle 140 to
move trigger 160 from the extended position toward the retracted
position to open a path or passageway for the liquid to be poured
from reservoir 130. The guided horizontal movement of trigger 160
moves stopper 180. Spout 170 provides guided movement (horizontal
and diagonal) to stopper 180. When a desired amount is poured,
trigger 160 is released to move back towards the extended position,
which moves stopper 180 (and allows stopper 180 to move) toward the
closed position and seat against spout 170.
[0039] Also, it is important to note that the term "server,"
"reservoir," " and "trigger" are intended to be broad terms and not
terms of limitation. These components may be used with any of a
variety of products or arrangements and are not intended to be
limited to use with liquid storing and dispensing applications.
Also, the term "coupled" shall mean the joining of two members
directly or indirectly to one another. Such joining may be
stationary in nature or movable in nature. Such joining may be
achieved with the two members or the two members and any additional
intermediate members being integrally formed as a single unitary
body with one another or with the two members or the two members
and any additional intermediate member being attached to one
another. Such joining may be permanent in nature or alternatively
may be removable or releasable in nature. Such joining may also
relate to mechanical, fluid, or electrical relationship between the
two components. Further, the terms of direction such as "vertical"
and "horizontal" are intended for clarity and in reference to when
the beverage server is its general upright position such as when
setting on a surface.
[0040] It is also important to note that the construction and
arrangement of the elements of the utensil as shown in the
preferred and other exemplary embodiments are illustrative only.
