Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims the priority from U.S. provisional
patent application Ser. No. 62/016,948 filed Jun. 25, 2014 and U.S.
provisional patent application Ser. No. 62/023,999 filed Jul. 14,
2014. The foregoing applications are incorporated in their entirety
herein by reference.
FIELD OF THE INVENTION
[0002] The present invention relates to a lid assembly. More
particularly, the invention relates to provide a substantially
resealable lid assembly for a container.
BACKGROUND
[0003] Containers are typically manufactured and sold with a
"one-time-use" lid assembly. At the time of use, the user will pull
up on a tab with his/her finger or otherwise puncture the lid
assembly, providing access to the interior space of the container.
In containers with tabs, for example, beverage cans, the lower
portion of the tab pushes a partially sheared portion of the lid
inward toward the fluid-holding portion of the can. As the
partially sheared portion of the lid is pushed into the can, the
material bends and yields, thus allowing the metal lid to be
permanently bent and displaced to provide a flow outlet for the
dispensation of liquid from the can and through the flow outlet in
the lid. While the tab remains attached to the lid by means of a
rivet and the partially sheared portion of the lid remains
displaced in the fluid-holding portion of the can, the user
typically bends the tab back to a position close to its initial
state, such as the its state prior to pulling up on the tab. In
this state, the can is considered to be "open" or "opened." In no
practical way can the partially sheared portion of the lid be bent
back upward and resealed to the portion of the lid from which it
was sheared.
[0004] Previous generations of cans used removable tabs that ended
up being tossed on the ground as trash. This was potentially
dangerous for those walking around without shoes, small children
(choking/swallowing hazard), and animals.
[0005] Typical motions like walking with an open can of soda in
your hand or driving a car with an open soda can in the cup holder
may often provide sufficient movement of the fluid in the opened
can to cause the fluid to splash around and eventually
involuntarily exit the can through the flow outlet. The fluid may
damage clothing, upholstery, electronics, and more.
[0006] Containers, including beverage containers, typically fail to
provide ventilation to the container as the fluid is being
dispensed from the container. As fluid is poured from a container,
the fluid leaving is replaced by an equal volume of air (i.e. the
"bloop, bloop, bloop . . . " sound as soda is poured from a can).
Without ventilation, the volumetric replacement of fluid with air
agitates the carbonated beverage, increases the head (foam) in the
cup into which the beverage is being poured, may increase the
likelihood of splatter (i.e. damage to clothing, upholstery,
electronics, etc.), and prolongs the time it takes to empty an
entire can in a single pour.
[0007] Furthermore, no currently existing known container designs
that provide for a structure to close the can after it has been
opened in order to reduce the likelihood of splashing, spilling,
etc. while walking, driving, or doing other physical activities
that create motion of the liquid in the can. Some aftermarket
devices exist that allow the user to close a soda can after it has
been opened, but these products are not directly integrated into
the soda can itself and can be cumbersome to operate. These
externally applied products are also choking/swallowing hazards for
small children and animals.
[0008] Therefore, a need exists to solve the deficiencies present
in the prior art. What is needed is a lid fixable to a container
that can be resealed. What is needed is a lid that can be easily
altered between an opened state and a closed state. What is needed
is a substantially resealable lid with a valve to increase fluid
flow dynamics. What is needed is a method of manipulating the lid
of a container between a sealed and an unsealed state.
SUMMARY
[0009] An aspect of the invention advantageously provides a lid
fixable to a container that can be resealed. An aspect of the
invention advantageously provides a lid that can be easily altered
between an opened state and a closed state. An aspect of the
invention advantageously provides a substantially resealable lid
with a valve to increase fluid flow dynamics. An aspect of the
invention advantageously provides a method of manipulating the lid
of a container between a sealed and an unsealed state.
[0010] The lid assembly detailed in this disclosure remedies the
deficiencies of current container lid assemblies by providing the
mechanical functionality to temporarily close a container after it
has been opened for the first time.
[0011] In an embodiment of this disclosure, after the container is
opened for the first time, a valve lid layer can be rotated in
either a clockwise or counter clockwise direction to open or close
the container. The valve lid layer can be also be partially rotated
between opened and closed orientations to provide for a partially
opened state. The direction of rotation required to open or close
the can may be dependent on the physical location of some of the
various components within the lid assembly.
[0012] Accordingly, the disclosure may feature a lid assembly
installable on a container. The lid assembly may include an
external lid layer, valve lid layer, a tab, and optionally a

external lid layer via a pivot. The tab may be operatively
connected to the valve lid layer. The sealant may be applied to at
least part of the lid assembly. The valve lid layer may be
rotatable via the pivot. The lid assembly may be substantially
continuously variable between a closed configuration and an opened
configuration via the tab.
[0013] In another aspect, the lid assembly may include an outer
engagement channel of the external lid layer and an outer
engagement rim of the valve lid layer receivable by the outer
engagement channel. The outer engagement rim may be locatable at
least partially within the outer engagement channel to
substantially seal a space enclosable by the lid assembly.
[0014] In another aspect, the tab may be configurable between a tab
up position and a tab down position.

layer. The lid assembly may be substantially continuously variable
between a closed configuration and an opened configuration. Moving
the tab at least partially within the length of the tab slot hole
causes the valve lid layer to rotate via the pivot to vary a flow
aperture. The tab may be configurable between a tab up position and
a tab down position. The valve lid layer may be substantially
immobilized while the tab is in the tab down position. The valve
lid layer may be substantially rotatable via the pivot while the

DETAILED DESCRIPTION
[0060] The following disclosure is provided to describe various
embodiments of a resealable lid assembly. Skilled artisans will
appreciate additional embodiments and uses of the present invention
that extend beyond the examples of this disclosure. Terms included
by any claim are to be interpreted as defined within this
disclosure. Singular forms should be read to contemplate and
disclose plural alternatives. Similarly, plural forms should be
read to contemplate and disclose singular alternatives.
Conjunctions should be read as inclusive except where stated
otherwise.
[0061] Expressions such as "at least one of A, B, and C" should be
read to permit any of A, B, or C singularly or in combination with
the remaining elements. Additionally, such groups may include
multiple instances of one or more element in that group, which may
be included with other elements of the group. All numbers,
measurements, and values are given as approximations unless
expressly stated otherwise.
[0062] Various aspects of the present invention will now be
described in detail, without limitation. In the following
disclosure, a resealable lid assembly will be discussed. Those of
skill in the art will appreciate alternative labeling of the
resealable lid assembly as a resealable can lid, container lid,
resealable cap, cover, top, the invention, or other similar names.
Similarly, those of skill in the art will appreciate alternative
labeling of the method of resealably opening a lid assembly as a
container resealing, selectively accessing a container, method,
operation, the invention, or other similar names. Skilled readers
should not view the inclusion of any alternative labels as limiting
in any way.
[0063] Referring now to FIGS. 1-26, the resealable lid assembly
will now be discussed in more detail. The resealable lid assembly
may include a lid assembly, external lid layer 26, valve lid layer
34, pivot 20, tab 18, flow outlet components, optional vent
components, tab slot components, seals, and additional components
that will be discussed in greater detail below. The resealable lid
assembly may operate one or more of these components interactively
with other components to provide a substantially resealable lid for
a container 28.
[0064] Unless otherwise specified, all references to lids and lid
assemblies in this disclosure relate to lids attachable to a
container 28, for example, cans. References to lid assemblies may
also extend to lids that are attached to beverage cans, soda cans,
beverage containers, food containers, and/or any other fluid-filled
vessels that utilize a lid to retain the contents of the
vessel.
[0065] Additionally, unless otherwise specified, references made to
containers 28 may include vessels for liquids, foods,
non-consumable fluids, and other substances. The containers 28
and/or lid assemblies may be constructed using a variety of
materials, including metals, plastics, synthetics, rubbers, and/or
other materials that would be apparent to those of skill in the
art.
[0066] While containers, including metal cans, may be used for many
purposes, one of the more widely used functions is for fluid
packaging, more specifically, fluid packaging of carbonated
beverages. Throughout this document, "lid" or "lid assembly" may be
used interchangeably to describe the portion of the can assembly
that may reside on the top portion of the container and may
substantially seal the liquid in the container. Furthermore, a soda
can, beverage can, beverage container, or fluid-filled vessel may
be referred to as "container," "can," or "can assembly." References
to lids and cans throughout this document are general statements
and are exemplary or illustrative of typical use for the purpose of
explaining this design. In some cases, "can" may refer to the
entire assembly of can and lid (or lid assembly) and this will be
discernable based upon the context. Every effort will be made to be
clear and concise throughout the specification for this patent
application. Furthermore, the lid assembly may be interchangeably
referred to as "device" or "apparatus" throughout this document. It
is not the intent of this application to make any additional limit
of the disclosed embodiments as requiring the fluid-holding portion
of the can (i.e. deep drawn portion of can). More specifically, it
is the intent of this application to focus on the means by which
fluid is retained by and dispensed from a can by introducing a
novel and unique lid assembly design, which may include an
integrated valve in some embodiments.
[0067] The lid assembly may generally include two components: an
external lid layer 26 and a valve lid layer 34 that are rotatable
about a pivot 20. These two components, which may also be included
with several other components and features, may provide the overall
mechanical functionality for the lid assembly. The lid assembly may
be adaptable to existing containers 28 or interchangeable with
existing container lids, for example beverage can lids. When used,
the lid assembly may provide an ability to close a container 28,
such as a beverage can, even after it has been opened.
[0068] The lid assembly may be made independently of the
fluid-holding portion of the container 28. An example of a
container may include, without limitation, metal components may be
shaped and constructed via conventional metal stamping or forming.
In one example of attaching a lid assembly to a container, metals
that are typically used for such products may be slightly elastic
and provide the ability for the device to deflect and deform based
upon the stiffness of the material, the force applied to the part,
and the geometry of the part. The lid assembly can interchangeably
replace existing can lids. Optimally, the lid assembly of this
invention may universally replace all existing container lids with
this advantageous and more functional design.
[0069] Referring now to FIGS. 1-11, the external lid layer 26 will
now be discussed in greater detail. The external lid layer 26 may
be virtually any size and/or shape compatible with a container 28
on which it may be attached. In one embodiment, the external lid
layer 26 may be a substantially round disk that is stamped and/or
formed in a flat or convex shape with the convex side upward facing
orientation. The external lid layer 26 may include cutouts, for
example, a flow outlet hole 16, an optional vent hole 262, a finger
tab slot hole 24, and a pivot hole 50. A pusher feature upset 48
may be included near an end, for example the counterclockwise-most
end, of the finger tab slot hole 24 to allow for concealment of
pusher features 144 includable on the finger tab 18.
[0070] Once the external lid layer 26 has been formed and/or
blanked, a secondary process may be performed to apply optional
sealant around the openings in the external lid layer 26. The
sealant may be applied locally to the bottom-facing flat or concave
surface around the outlines of each of the openings or to the
entire bottom-facing flat or concave surface of the external lid
layer 26.
[0071] In one embodiment, the external lid layer 26 may be a
substantially circular piece of material that includes the flow
outlet hole 16 and finger tab slot hole 24, through which at least
part of a tab 18 may be passed. The external lid layer 26 may
optionally include a vent hole, which may provide a pathway for air
or another fluid to pass between the interior and exterior of the
container 28 on which the lid assembly is installed.
[0072] Referring now to FIGS. 2-6 and 10-11, the valve lid layer 34
will now be discussed in greater detail. The lid assembly may
include a valve lid layer 34 that may be rotated about a pivot 20
with respect to the external lid layer 26. The valve lid layer 34
may include a flow outlet 54, flow upset 14, tab slot upset 22, and
pivot hole 52. The tab slot upset 22 may be provided as a ramp. The
valve lid layer 34 may be virtually any shape that provides the
flow outlet 54 and flow upset 14. The tab slot upset 22 may provide
the ability to partially open, fully open, partially close, and
fully close a beverage can by limiting how much fluid can flow out
of the can based upon the size of the adjusted flow aperture.
[0073] The valve lid layer 34 may be rotatable via the pivot 20.
The valve lid layer 34 may be virtually any size and/or shape
compatible with additional components of the lid assembly. The
valve lid layer 34 may be configured with dimensions allowing the
valve lid layer 34 to be located at least partially within a
container 28 on which the lid assembly may be attached. In one
embodiment, the valve lid layer 34 may be a substantially round
disk that is stamped and/or formed in a flat or convex shape with
the convex side upward facing orientation. The valve lid layer 34
may include cutouts, for example, a flow outlet 54 and optionally a
vent. The valve lid layer 34 may additionally include upsets, for
example, the flow upset 14, tab slot upset 22, and optionally a
vent upset. The valve lid layer 34 upsets may facilitate engagement
and mating features of the lid assembly. The pivot hole 52 may be
substantially aligned with the pivot hole 50 of the external lid
layer 26. A pivot 20 may be inserted through both pivot holes 50,
52. The tab 18 may be operatively attached to the valve lid layer
34, for example, via the slot tab upset 22. The valve lid layer 34
may omit additional holes for ventilation due to the ventilation
permitted by the deflection of the tab slot upset 22 as it creates
an air flow path through the tab slot hole 24 as the valve lid
layer 34 is rotated.
[0074] Referring now to FIGS. 2-3 and 10-11, an illustrative
engagement structure between the external lid layer 26 and the
valve lid layer 34 will now be discussed, without limitation. The
external lid layer 26 may include an outer engagement channel 12.
The valve lid layer 34 may include an outer engagement rim 44 that
is compatible with the outer engagement channel 12. The outer
engagement channel 12 and corresponding rim 44 may facilitate
alignment between the external lid layer 26 and the valve lid layer
34. The outer engagement channel 12 and corresponding rim 44 may
also enhance a seal between these parts.
[0075] The lid assembly may additionally include a flow upset
engagement channel 42 and corresponding flow outlet hole engagement
lip 33 to enhance the seal made when the lid assembly is locked in
the closed position. For example, a force that presses the valve
lid layer 32 against the external lid layer 26 when the tab 18 is
in a tab down position may additionally press the flow outlet hole
engagement lip 33 against the flow upset engagement channel 44,
substantially closing the flow aperture and sealing the flow outlet
components.
[0076] In one embodiment of this disclosure, the outer engagement
channel 12 may be circumferentially located about the external lid
layer 26 with a radius that is smaller than a substantially
circumferential attachment interface between the lid assembly and
container 28. The outer engagement rim 44 may substantially fit
within the outer engagement channel 12 when the lid assembly is in
the closed configuration. Additionally, the outer engagement rim 44
may be at least partially displaced from the outer engagement
channel 12 as the lid assembly is unsealed, which may occur as a
step to move the lid assembly into the opened configuration.
[0077] Referring now to FIGS. 1-11, the pivot 20 will now be
discussed in greater detail. The pivot 20 may be at least partially
inserted with a pivot hole 50 on the external lid layer 26 and a
pivot hole 52 on the valve lid layer 34. The pivot 20 may be
substantially fixed to pivot hole 50 of the external lid layer 26,
allowing the valve lid layer 34 to rotate at least partially via
the pivot 20 passing through the pivot hole 52 of the valve lid
layer 34. Alternatively, the pivot 20 may be movable within the
pivot hole 50 of the external lid layer 26 and substantially fixed
to the pivot hole 52 of the valve lid layer 34. In yet another
configuration, the pivot 20 may be substantially movably located
within the pivot holes 50, 52 of the external lid layer 26 and the
valve lid layer 34, respectively, allowing valve lid layer 34 may
be movable via the pivot 20 passing through its pivot hole 52. The
pivot 20 may additionally pass through the tab 18.
[0078] The pivot 20 may provide a mechanical attachment and
rotational alignment between the external lid layer 26 and the
valve lid layer 34. The pivot 20 may include a rivet or other
structure. Multiple pivots may optionally be provided, affecting
movement of various features of the external lid layer 26 and/or
the valve lid layer 34. A pivot seal may be applied to at least
part of the bottom surface of the external lid layer 26 and/or a
surface of the valve lid layer 34 to provide a hermetic seal
between the pivot 20 and layers of the lid assembly.
[0079] Referring now to FIGS. 1-13, the tab 18 will now be
discussed in greater detail. The tab 18 may be virtually any length
of material extending from the valve lid layer 34 through at least
part of the external lid layer 26. The valve lid layer 34 may be at
least partially rotatable via the pivot 20 via the tab 18. The tab
18 may be provided as a foldable finger tab that permits
stackability of containers 28 including the lid assembly. Inclusion
of a foldable tab advantageously reduces the likelihood of the tab
18 being accidentally contacted and the substantially hermetic seal
of the lid assembly being breached by subsequent containers 28 in a
stack, for example, multiple cans in other packaging configurations
such as boxes.
[0080] The tab 18 may utilize features that simultaneously push up
on the bottom surface of the external lid layer 26 and then down on
the top surface of the valve lid layer 34 to create a separation
force between the external lid layer 26 and the valve lid layer 34.
This separation force may at least partially breach or break the
seal so that the valve lid layer 34 may rotate freely with respect
to the external lid layer 26. The tab slot upset 22 may be
configured as a ramp, which may further apply a separation force
between the external lid layer 26 and the valve lid layer 34 as the
tab 18 is moved about the tab slot hole 24, for example, to the
opened position.
[0081] In one embodiment, the tab 18 may be configured as a piece
of formed sheet metal with similar construction to a conventional
soda can tab. A central end of the tab 18 may be attached near the
center of the lid assembly, for example, at or near the pivot 20.
The pivot 20 may pass through a pivot hole 152 of the tab 18. A
distal end of the tab 18 may extend outwardly from the center of
the lid assembly, for example, to the outer circumference or edge
of the lid assembly. The distal end of the tab 18 may be attached
to the valve lid layer 34 at its far end via pivots, welds, or
other similar mechanical attachment structures as the tab central
end. The tab may additionally include a pusher dimple 145 at the
end of a pusher tooth 146 at the distal end of the tab 18. A weight
reduction feature 142 may be included to decrease the quantity of
material required to construct the tab 18, and thus the weight of
the tab 18.
[0082] A bendable portion of the tab 18 may be connected to the
attachment locations about a bend line 150. In its initial state,
the tab 18 may substantially prevent the tab 18 from being
displaced in a downward direction and accidentally breaking the
hermetic seal. When the user is ready to "open" the container 28,
the user may merely engage the fingertip grip feature 148 to flip,
or bend the tab "up". As an example, the user may grip the tab 18
between index finger and thumb and rotate the tab 18 about the main
rotation axis to rotate and thus open/close the lid once the seal
is broken. Pusher features 144 may be located on the finger tab 18
at the tab distal end to separate the valve lid layer 34 from the
lid seals as the tab is bent upwards. As the separation occurs, the
valve lid layer 34 may be deflected in a downward direction, thus
continuing to add to the separation between external lid layer 26
and the valve lid layer 34.
[0083] Referring now to FIGS. 1-11, the flow outlet 54, flow outlet
hole 16, flow upset 14, and flow aperture will now be discussed in
greater detail. As discussed above, the external lid layer 26 may
include a flow outlet hole 16. Additionally, the valve lid layer 34
may include a flow outlet 54 and a flow upset 14. In a closed
configuration, the flow upset 14 may be located substantially
within the flow outlet hole 16, substantially closing the flow
aperture and preventing the egress of liquid through the lid
assembly. In an opened configuration, the flow upset 14 may be
located away from the flow outlet hole 16, substantially opening
the flow aperture and permitting egress of liquid through the lid
assembly. The flow outlet 54 may substantially align with the flow
outlet hole 16 to increase the flow aperture and allow the egress
of liquid from the container 28. The lid assembly may be configured
at least partially between the opened configuration and the closed
configuration, providing a flow aperture that is partially opened.
The flow upset 14 of the valve lid layer 34 may provide for
mechanical engagement, which may include a between the flow upset
14 of the valve lid layer 34 and flow outlet hole 16 of the
external lid layer 26 to enhance the seal when closed. The
mechanical engagement may be enhanced by the flow upset engagement
channel 42 and the flow outlet engagement lip 33.
[0084] Referring now to FIGS. 1 and 3-9, the tab slot hole 24 and
tab slot upset 22 will now be discussed in greater detail. As
discussed above, the external lid layer 26 may include a tab slot
hole 24 and the valve lid layer 34 may include a tab slot upset 22.
The tab slot upset 22 in the valve lid layer 34 may provide for
deflection of the valve lid layer 34. The tab 18 may be operatively
attached to at least part of the tab slot upset 22. The tab 18 may
be passed at least partially through the tab slot hole 24. The tab
18 may be moved within a length provided by the tab slot hole 24.
Movement of the tab 18 within the tab slot hole 24 may adjust the
orientation of the valve lid layer 34. Thus, movement of the tab 18
may adjust the positions of the flow outlet 54 and flow upset 14
with respect to the flow outlet hole 16, further adjusting the flow
aperture. Moving the tab 18 about the tab slot hole 24 may also
adjust the mechanical separation between the external lid layer 26
and valve lid layer 34 as the valve lid layer 34 is rotated to a
partially or fully opened state. The tab slot upset 22 may include
a pusher dimple 45, which may facilitate loosening the seal when
the lid assembly is altered between the closed configuration and
the opened configuration.
[0085] Referring now to at least FIG. 2, the flow seal 32 will now
be discussed in greater detail. The flow seal 32 may substantially
prevent egress of fluid through the flow outlet hole 16 while the
lid assembly is in the closed configuration. The flow seal 32 may
be mechanically attached to the bottom surface of the external lid
layer 26 and may provide a hermetic seal between the external lid
layer 26 flow outlet hole 16 and valve lid layer 34 flow upset 14.
A slot seal may also be included that may be mechanically attached
to the bottom surface of the external lid layer 26 and may provide
a hermetic seal between the external lid layer 26 tab slot hole 24
and/or optional vent hole and valve lid layer 34 tab slot upset
22.
[0086] In one embodiment, while the flow seal 32 is still in an
un-cured or partially cured state, the external lid layer 26, valve
lid layer 34, and tab may be aligned to one another, assembled, and
then pivoted together with the external lid layer 26 on top and the
valve lid layer 34 on the bottom. The feature alignment may ensure
that the flow dimple 35 of the valve lid layer 34 may be aligned
with the respective receiving cutout in the external lid layer 26.
An optional vent dimple in the valve lid layer 34 may be aligned
with the respective optional receiving vent cutout in the external
lid layer 26. The tab 18 may be inserted into the tab slot hole 24.
The pivot holes 50, 52 on all parts may be axially aligned. The
pivots 20 may then be inserted into their respectively aligned
pivot holes 50, 52 and may be deformed to as required. The pivot 20
may provide sufficient force to the flow seal 32 and other seals
between the external lid layer 26 and valve lid layer 34 so that
the sealant may become slightly compressed and form a high quality
substantially hermetic seal around each of the openings.
[0087] Referring now to at least FIGS. 2-3, and 10, the sealant 37
will now be discussed in greater detail. The sealant may be applied
to at least part of the lid assembly to facilitate creating a seal
while in the closed configuration.
[0088] Further sealing and alignment between the external lid layer
26, valve lid layer 34, other parts of the lid assembly, and the
container 28 may be accomplished by the alignment channel and
alignment lip on the external lid layer 26 and valve lid layer 34,
respectively. These features may enhance the alignment between the
parts and may advantageously provide for another sealant
location.
[0089] In operation, the lid assembly may be used to reversibly
open and substantially reseal a container 28. The operation may
include configuring the tab 18 in a tab up position, such as
illustrated in FIGS. 1-2, 4, 7, 10, and 12, to unlock the lid
assembly. By configuring the tab in the tab up configuration, such
as illustrated in FIGS. 5-6, 8-9, 11, and 13, the valve lid layer
34 may be at least partially separated from the external lid layer
26 to enable rotation of the valve lid layer 34 via the pivot 20.
The tab 18 may be operatively connected to the valve lid layer 34.
The operation may additionally include moving the tab 18 within a
length of a tab slot hole 24 of the external lid layer 26. By
moving the tab 18, the valve lid layer 34 may be rotated via the
pivot 20. Rotation of the valve lid layer 34 may alter the lid
assembly between a closed configuration, such as illustrated in
FIGS. 1-2, 4, 7-8, and 10-11, and an opened configuration, such as
illustrated in FIGS. 5 and 9.
[0090] In one example, the lid assembly, including the valve lid
layer 34, may start in the closed configuration, as illustrated in
FIGS. 4 and 7. In this closed configuration of the lid assembly,
the flow upset 14 may be oriented below the flow outlet hole 16.
With the tab 18 in the down position, the flow aperture may be
substantially closed and sealed. The tab 18 may then be moved into
the tab up position, moving the valve lid layer 34 away from the
external lid layer 26, as illustrated in FIG. 8, and thus moving
the flow upset 14 away from its resting place in the flow outlet
hole 16.
[0091] The tab 18 may then be moved about the length of the tab
slot hole 24 to rotate the valve lid layer 34 via the pivot 20. As
the valve lid layer 34 is rotated, the flow upset 14 may be moved
away from the flow outlet hole 16 and a flow outlet 54 may be moved
closer to the flow outlet hole 16 to vary a flow aperture. When the
flow aperture is sufficiently opened, as illustrated in FIGS. 5 and
9, a fluid may egress from the flow outlet hole 16 through the flow
aperture.
[0092] When the valve lid layer 34 is in the desired orientation
with respect to the external lid layer 26, the tab 18 may be moved
into the tab down position. With the tab 18 in the tab down
position, the valve lid layer 34 may be substantially locked into
place with respect to the external lid layer 26. To reseal the
container 28, the above illustrative operation may be performed in
reverse to again locate the flow upset 14 in the flow outlet hole
16 in a substantially locked configuration.
[0093] The valve lid layer 34 may be partially rotated between the
closed configuration and the opened configuration, as illustrated
in FIG. 6. In a partially opened configuration, the flow outlet 54
of the valve lid layer 34 may be located less than completely under
the flow outlet hole 16 of the external lid layer 26, providing a
partially opened flow aperture. Skilled artisans will appreciate
various configurations in which the lid assembly may be opened
between fully closed and fully opened after having the benefit of
this disclosure.
[0094] In one embodiment, filling the container 28 with a soda or
other beverage may increase the pressure inside the container 28,
for example due to carbonation. The increased pressure inside the
container 28 may apply a uniform pressure to the valve lid layer 34
essentially "helping" the valve lid layer 34 to remain closed.
[0095] Additionally, upon the first use of the container 28, the
user may bend the finger tab 18 up or otherwise manipulate the tab
18 into the tab up position. This action may cause pusher features
145, 146 on the tab to engage the respective pusher features 35 on
the external lid layer 26, thus causing the tab pusher features
145, 146 to push up on the bottom surface of the external lid layer
26 and down on the top surface of the valve lid layer 34. This
force and respective deflection may cause the valve lid layer 34 to
substantially peel away from a sealant and initially relieve any
pressure in the can.
[0096] Once the valve lid layer 34 is peeled away from the sealant,
the user may apply a lateral force to the tab 18 to rotate the tab
18 in a direction, for example a clockwise direction. The tab 18
may be rotated until it contacts the far end of the tab slot hole
24, substantially aligning the flow outlet 54 of the valve lid
layer 34 with the flow outlet hole 16 in the external lid layer 26.
The lid assembly can be adjusted in-between fully opened and fully
closed as well by merely rotating the tab in various directions,
for example a clockwise or counterclockwise direction, thus
changing the effective size of the flow aperture or orifice. After
the initial opening, the user can open and close the lid several
times.
[0097] Referring now to FIGS. 14-26, along with FIGS. 1-13
described above, an additional embodiment of the disclosure will be
described below. This embodiment may similarly include a lid
assembly with an external lid layer 226, valve lid layer 234, tab
218, sealant, seals and other features. This embodiment of the lid
assembly may provide for the ability to close a container even
after it has been opened. The lid assembly may include a pivot 220
that provides a mechanical attachment and rotational alignment
between the external lid layer 226 and valve lid layer 234. The lid
assembly of this embodiment may additionally include a tab 218 that
provides for stackability of containers.
[0098] Similar to the discussion above, this embodiment may include
a flow upset 214 in the valve lid layer 234 that provides for
mechanical engagement between the valve lid layer 234 and flow
outlet hole 216 of the external lid layer 226 to enhance the seal
when closed. This embodiment may additionally include seals,
including a flow seal, that may be mechanically attached to the
bottom surface of the external lid layer 226 and provide a
substantially hermetic seal between the external lid layer 226 flow
outlet hole 216 and valve lid layer 234 flow upset 214. A flow
aperture may be adjusted by changing orientation of the flow upset
214 and a flow outlet 254 with respect to the flow outlet hole 216.
This embodiment may additionally include a sealant 237, which may
be applied to at least part of the lid assembly to facilitate
creating a seal while in the closed configuration.
[0099] Referring additionally to FIGS. 14-26, the tab 218 will now
be discussed. The tab 218 may be operatively connected to a tab
base 217. The tab base 217 may be operatively connected to valve
lid layer 234, for example, via a tab slot upset 222 of the valve
lid layer 234. The tab base 217 may be a piece of material, for
example sheet metal, which may be attached to the valve lid layer
234, for example, via spot welds or rivets. A rotatable tab 218 may
be pivotally connected to the tab base 217. In the "down" position,
the tab 218 may prevent the tab 218 from being displaced in a
downward direction and accidentally breaking the hermetic seal.
When the user is ready to "open" the container, the user may flip
the tab "up" and then vertically press in a downward direction on
the tab 218 to initially break the hermetic seal. The user may then
laterally press on the tab 218 and/or tab base 217 to open/close
the lid assembly once the seal is broken. The vertical deflection
feature of the tab 218 may prevent the lid from becoming
over-deflected and taking a permanent set.
[0100] Referring now to FIGS. 14 and 16-23, the tab slot hole 224
and tab slot upset 222 will now be discussed. The external lid
layer 226 may include a tab slot hole 224, which may be similar in
construction to the tab slot hole 24 discussed above, to facilitate
travel of a tab 218 throughout the length of the tab slot hole 224.
The valve lid layer 234 may include a tab slot upset 222, which may
be similar in construction to the tab slot upset 22 discussed
above. The tab slot upset 222 of this embodiment may be
substantially fitted into the tab slot hole 224 when the lid
assembly is in the closed configuration, substantially sealing the
tab slot hole 224. When the valve lid layer 234 is rotated to place
the lid assembly in the opened configuration, at least part of the
tab slot upset 222 may be rotated under a vent hole 262.
[0101] Referring to FIGS. 14 and 16-23, the vent hole 262 and vent
upset 264 will now be discussed. The vent hole 262 and vent upset
264 are provided in this example to illustrate a possible
configuration that includes discrete venting structures. Skilled
artisans will appreciate additional configurations of this and
other embodiments that exclude the vent hole 262, vent upset 264,
or both. Illustration of the vent hole 262 and vent upset 264 in
FIGS. 14 and 16-23 are not intended to limit this disclosure to
embodiments including discrete venting structures or other specific
venting structures in any way.
[0102] The external lid layer 226 may include a vent hole 262,
which may allow air or other fluids to pass when the lid assembly
is in the opened configuration. The valve lid layer 234 may include
a vent upset 264, which may be substantially fitted into the vent
hole 262 when the lid assembly is in the closed configuration,
substantially sealing the vent hole 264. When the valve lid layer
234 is rotated to place the lid assembly in the opened
configuration, at least part of the vent upset 262 may be rotated
away from its original location under the vent hole 264 to vary a
vent aperture. At least part of the tab slot upset 222 may be
rotated under the vent hole 262, which may provide a gap though
which air or other fluids may be vended when the lid assembly is in
the opened configuration.
[0103] While various aspects of the invention have been described
in the above disclosure, the description of this disclosure is
intended to illustrate and not limit the scope of the invention.
The invention is defined by the scope of the appended claims and
not the illustrations and examples provided in the above
disclosure. Skilled artisans will appreciate additional aspects of
the invention, which may be realized in alternative embodiments,
after having the benefit of the above disclosure. Other aspects,
advantages, embodiments, and modifications are within the scope of
the following claims.
