[0049] In one aspect, the present invention relates to storing,
dispensing and closure devices. The closure devices of the present
invention can be used to separately house, store or carry a dose or
supply of one or more ingredients, formulations or products to
maintain freshness and integrity of the ingredients until dispensed
at point-of-use into a separate receiving vessel. When activated
the closure devices of the present invention delivers or dispenses
the stored dose or supply of one or more ingredients, formulations
or products to the receiving vessel without the removal of the
closure device from the receiving vessel thereby eliminating spills
and contamination. The combined contents of the receiving vessel
can be dispensed for consumption by the closure devices of the
present invention without removing the closure device from the
receiving vessel. The closure devices can be opened for consuming
the combined contents, can be closed to prevent spilling of the
combined contents, and can be reopened and closed again, if
desired.
[0050] In some embodiments, the closure device comprises a base, a
sleeve for dispensing a dose or supply of the one or more
ingredients, formulations or products into a receiving vessel, a
spout for dispensing the combined contents of the receiving vessel
for consumption, an end cap and a dust cover. In some embodiments,
the sleeve sits atop and engages a base and a spout sits atop and
engages the sleeve. In some embodiments, the dust cover sits atop a
portion of the base, and the entire sleeve and spout when closure
device is in an inactivated state. The end cap is located at the
distal portion of the base.
[0051] In some embodiments, the sleeve, end cap and dust cover
cooperate in a concerted action to dispense the one or more
ingredients into a receiving vessel.
[0052] In some embodiments, an outer diameter of the sleeve is
configured with a helix or like device that is engaged with a helix
or like device on an inner diameter of the dust cover such that
when the dust cover is rotated, this action drives the sleeve and
end cap in a downward direction releasing ingredients from the
product chamber. In some embodiments, the sleeve comprises a center
post which acts directly and applies a pressing force on the end
cap when the sleeve is driven in a downward action.
[0053] In some embodiments, once the dust cover is rotated properly
and ingredients are released, the dust cover can then be removed
from the base. In some embodiments, the spout can be pulled open or
twisted open by a user so that the combined contents of the
receiving vessel can be emptied through the spout.
[0054] In some embodiments, the dust cover is held in position on
the base by one or more lug and groove combinations configured to
move/work in combination with the sleeve such that the dust cover
is not readily removed from the base until appropriate lug and
groove combinations are aligned. In some embodiments, the alignment
and radial movement required to make the dust cover align for
removal drives the sleeve and end cap from the closed position to
the open position. In some embodiments, the dust cover lugs and
cooperating groove sequence in the base portion do not allow a user
access to ingredients prior to their release from the product
chamber past the end cap into an appropriate receiving vessel.
[0055] In some embodiments, the base 1 comprises a product chamber
3 and closure skirt 4; the sleeve comprises a center post 6, a base
engaging seal portion 28 and a spout engaging seal portion 18; the
spout 5 comprises an outlet 17 capable of receiving a stem of the
center post 8 and allowing the combined contents of the receiving
vessel to pass through the closure device, one or more side walls
having inner and outer diameters, a sealing member 21 for engaging
the stem of the center post 8 to create a seal when the spout is in
its most distal, closed state. In some embodiments the closure
device further comprises a receiving vessel attached to the closure
device capable of receiving the one or more ingredients dispensed
from the closure device.
[0056] The sleeve 12 engages with the base and is capable of moving
relative to the base in an axial direction. In some embodiments,
the sleeve 12 comprises a center post 6, a base engaging seal

[0090] Details of the components and features of the closure
devices of the present invention are described more fully
below.
Base
[0091] The closure devices of the present invention comprise a base
1 comprising a product chamber 3 for storing one or more
ingredients, formulations or products and a closure skirt 4 for
attaching the closure device to a receiving vessel.
[0092] In some embodiments, the base 2 has a proximal top which
acts as a sleeve stop 16 which prevents further downward movement
of the sleeve, a distal end, one or more side walls and an internal
volume.
[0093] In some embodiments, the proximal top of the base comprises
one or more openings 31 that enable dispensing the contents of a
receiving vessel for consumption from the receiving vessel through
the base 1, sleeve 12, spout 5 and ultimately the outlet 17 of the
spout 5.
[0094] In some embodiments, the proximal top of the base 1 is
covered by the sleeve 12. The one or more side walls of the base 2
have one or more inner and outer diameters. In one embodiment, each
of the inner diameter of the side walls and the outer diameter of
the side walls are substantially the same along their respective
length from the proximal top to the distal end of the base 1. In
other embodiments, there is more than one of each of the inner and
outer diameters of the side walls along the length of the side
walls from the proximal end to the distal end of the base 1. In
some embodiments, the side walls have a distal annular edge at
their distal end. In one embodiment the side walls of the base are
curved to give the base a tubular shape. The tubular shape of the
base 2 may be conical including any tapered or multi-sized tubular
or cylindrical form. In another embodiment the side walls of the
base 1 are flat having three or more side walls forming an angular
tube shape. The inner diameter of the side walls at the distal end
of the base 1 interferingly engages the outer diameter of the end
cap 7.
[0095] In some embodiments, the base comprises a sleeve engaging
portion 30 that engages the base with the sleeve. In some
embodiments, the outer diameter of the side walls of the sleeve
engaging portion of the base 30 interferingly engage the inner
diameter of the side walls of the base seal portion of the sleeve
28. In some embodiments, the sleeve engaging portion of the base 30
comprises one or more distal end base beads 23 which provide radial
interference on the inner diameter of the base seal portion of the
sleeve 28.
[0096] In some embodiments, the distal end of the base 1 comprises
a distal annular edge of the side walls. When the closure device of
the present invention is in an inactivated state (i.e., prior to
point-of-use dispensing of stored one or more ingredients,
formulations or products), the distal end of the base 1 is closed
by the end cap 7 and/or an end plate seal or combination thereof.
When the closure devices of the present invention are in an
activated state (i.e., after point-of-use dispensing of stored one
or more ingredients, formulations or products), the distal end of
the base 1 is open to allow the dispensed one or more ingredients,
formulations or products to combine with contents of a receiving
vessel and to allow consumption of the combined contents of the
receiving vessel. The distal end of the base housing 2 further
comprises a dispensing port 58 when the closure device is in the
activated state. Referring to FIG. 6, upon actuation, there is
provided a dispensing port 58 at the distal end of the base 1
allowing the one or more ingredients, formulations or products to
exit the internal volume of the base 1 and be dispensed into the
receiving vessel.
[0097] In some embodiments, the internal volume of the base 1 is
used to store the one or more ingredients, formulations or
products. Since there are openings in the base 1 that lead to the
sleeve 12 and spout 5 portion of the closure device, the one or
more ingredients, formulations or products can also be present in
these spaces of the closure device in the inactivated state. The
internal volume of the base is also referred to as the product
chamber 3. In some embodiments the volume of the product chamber 3
is predetermined for dosing and supplying methods. The product
chamber 3 has a proximal top, a distal end, and one or more side
walls as described above for the base 1.
[0098] The type and form of the one or more ingredients,
formulations or products stored in the product chamber 3 is
unlimited. In some embodiments there is a single ingredient,
formulation or product and in other embodiments there is a
combination of ingredients, formulations and/or products.
Non-limiting exemplary forms of ingredients, formulations or
products include powders, dehydrated constituents, liquids, liquid
concentrate and suspensions. Non-limiting examples of the types of
ingredients, formulations or products that can be stored and
dispensed from the closure devices of the present invention include
dietary supplements (e.g., fiber and vitamins), sport nutrition
ingredients (e.g., amino acids, fat burning agents, muscle
builders), diet nutrition ingredients (e.g., appetite suppressants,
fat burning agents, ingredients causing a feeling satiety),
ingredients with anti-aging benefits, immune supporting ingredients
(e.g., prebiotics, probiotics), energy boosting agents, stimulants,
anti-oxidants and anti-hangover formulations.
[0099] The ingredients, formulations and products capable of being
stored and dispensed from the closure devices of the present
invention can also include medicaments, biologics, microorganisms,
nutraceuticals, drugs, prodrugs and pharmaceuticals. It is
desirable to formulate a point of use form of delivering medicine
that avoids the need to swallow hard tablets or capsules, avoids
bad taste associated with more traditional forms of medicines and
maintains the product integrity.
[0100] Any of the one or more ingredients, formulations or products
stored and dispensed by the closure devices of the present
invention can be stored independently or in combination with other
ingredients such as, for example, flavoring, sweetening,
acidulants, excipients, preservatives and/or coloring agents.
[0101] Closure Skirt
[0102] The base 1 of the closure devices of the present invention
further comprises a closure skirt 4. The closure skirt 4 is capable
of engaging the neck finish or container opening of a receiving
vessel to provide sealed closure of the receiving vessel neck or
opening. In some embodiments, the closure skirt 4 has a greater
diameter than the sleeve engaging portion of the base 30. The
closure skirt 4 has a proximal top or deck, one or more peripheral
side walls, and a distal annular edge. As shown in FIGS. 2 and 4,
in some embodiments there are one or more longitudinal finger
recess elements 32 on the outer side walls of the closure skirt 4
for better grasping by the end user. In one embodiment, the closure
skirt 4 has threads on the internal side walls capable of being
rotatably coupled to a receiving vessel opening. In another
embodiment the closure skirt 4 is non-threaded. In some
embodiments, the closure skirt 4 comprises one or more depending
radial flexible members that fits to the inner diameter of a
receiving vessel opening. The depending radial member is designed
to have interfering engagement with the inner diameter of the
opening of a receiving vessel such that it seals the contents of
the receiving vessel from leaking out and still allows sufficiently
low application and removal forces to be readily applied and
removed by the end user. In some embodiments the closure devices of
the present invention are capable of providing sealing engagement
with a variety of container neck finishes and container opening
sizes of a receiving vessel and comprises the features and
functionality as described below for the universal closure
skirt.
Sleeve
[0103] The closure devices of the present invention comprise a
sleeve 12. The sleeve engages the base 1 and spout 5 of the closure
device. In some embodiments, the sleeve 12 is capable of moving in
an axial direction relative to the base 1. In some embodiments, the
sleeve comprises a center post 6 which acts on the end cap 7; a
base seal portion of the sleeve 28 which engages the base 1; and a
spout seal portion of the sleeve 18 which engages the spout 5. In
some embodiments, the base seal portion of the sleeve 28 comprises
one or more distal end sleeve beads 22 which provide radial
interference on the outer diameter of the sleeve engaging portion
of the base 30. In some embodiments, the spout seal portion of the
sleeve 18 comprises one or more spout seal beads 19 which provide
radial interference on the inner diameter of the lesser diameter of
the spout 27.
[0104] In some embodiments, the outer diameter of the sleeve, such
as the outer diameter of the base seal portion of the sleeve 28
comprises one or more sleeve helical thread forms 14 that engage
with the inner diameter of the dust cover 2 (such as a dust cover
helical thread forms 13) such that when the dust cover is rotated,
this action drives the sleeve 12, including the center post 6 and
end cap 7 in a downward direction. Downward vertical movement of
the center post 6 moves the end cap 7 beyond the distal end of base
1 to effect release of one or more ingredients, formulations or
products into a receiving vessel. In some embodiments, the dust
cover 2 does not participate in moving the sleeve 12 in a downward
direction. In some embodiments, the dust cover 2 can be removed,
and the sleeve 12 twisted manually by a user, driving the sleeve 12
in a downward direction, resulting in release of the one or more
ingredients, formulations or products into a receiving vessel.
[0105] Center Post
[0106] In some embodiments, the center post 6 has a cylindrical,
tubular or conical shape. In some embodiments, the center post 6
has one or more outer diameters, a proximal stem of the center post
8, an intermediate portion and a distal end. In some embodiments
the center post 6 further comprises one or more inner diameters. In
some embodiments the outer and inner diameters of the center post 6
are variable along the length of the center post 6. In some
embodiments, the proximal top of the stem 8 can be flat or rounded.
In one embodiment, the proximal stem of the center post 8 has a
greater outer diameter than the intermediate portion, distal end
and/or a combination thereof. In some embodiments, the diameter of
the stem of the center post 8 is greater than at least the
intermediate portion of the center post in a stepped, non-tapered
fashion such that there is a distal annular edge of the stem. In
other embodiments, the outer diameter of the center post 6 is
substantially the same along its length. In some embodiments, the
distal end of the center post 6 is configured to be in mating
engagement with the end cap 7. In some embodiments, the center post
6 is configured to be in axial alignment within the product chamber
3.
[0107] Upon application of a user-actuated twisting force of the
dust cover and/or sleeve, the center post 6 is capable of moving
axially in a downward vertical or distal direction toward the
distal end of the base 1. Distal movement of the center post 6
moves the end cap 7 in the downward or distal direction beyond the
distal end of the base 1 to effect release of the one or more
stored ingredients, formulations or products.
[0108] In some embodiments, the center post 6 is substantially
rigid and not intended to bend or flex to a deformable position. In
some embodiments, the rigidity of the center post 6 aids assembly
so that it can readily accept the end cap 7 in interfering
engagement. In some embodiments the center post 6 is intended to
remain engaged in the end cap 7 and not be readily removed from the
end cap 7. Upon application of user-actuated twisting force acting
on the sleeve, the center post 6 forces the end cap 7 in a downward
or distal direction beyond the distal end of the product chamber 3.
In some embodiments, the strength of the center post 6 needs to be
structurally sound enough to forcibly remove the end cap 7 from the
product chamber 3 where there is diametrical interference.
[0109] In some embodiments, the center post 6 is attached, e.g., to
the inside diameter of the side walls of the sleeve 12 by one or
more center post collar support ribs 15. In some embodiments, the
center post collar support ribs 15 can radiate from the inner
diameter of the base seal portion of the sleeve 28, spout seal
portion of the sleeve 18, or combinations thereof. In some
embodiments, the center post collar support ribs 15 are static and
maintain the static position of the center post relative to the
other sleeve portions. In other embodiments, there are optionally
one or more flexible hinge leg members in addition to or in lieu of
center post collar support ribs 15 to help maintain axial alignment
of the center post 6. In some embodiments, the flexible hinge leg
members can be attached to the inner diameter of the base seal
portion of the sleeve 28, or the spout seal portion of the sleeve
18 or combinations thereof and radiate therefrom and attach to the
center post 6 when used in lieu of center post collar support ribs
15. In some embodiments, flexible hinge leg members can be attached
to the side wall of the product chamber 3, the inner diameter of
the base seal portion of the sleeve 28, the spout seal portion of
the sleeve 18 or combinations thereof and radiate therefrom and
attach to the center post 6 when used in addition to the center
post collar support ribs 15. In some embodiments, flexible hinge
leg members can radiate perpendicularly from the inner diameter of
the product chamber 3. In other embodiments, flexible hinge leg
members can radiate at a non-perpendicular angle. In some
embodiments, flexible hinge leg members can attach to the proximal
stem of the center post 8. In some embodiments, the flexible hinge
leg members attach to the intermediate portion of the center post.
The flexible hinge leg members are capable of flexing and bending.
In some embodiments, when the center post 6 is in its inactivated
position (i.e., prior to point-of-use dispensing of stored one or
more ingredients, formulations or products), the flexible hinge leg
members are not in a flexed or bent position. In some embodiments,
the flexible hinge leg members bend in the distal direction as the
center post 6 is moved in the distal direction by a user-actuated
force. When the center post 6 is in its activated position (i.e.,
after point-of-use dispensing of stored one or more ingredients,
formulations or products), the flexible hinge leg member is in a
flexed or bent position.
[0110] Stem of the Center Post
[0111] The stem of the center post 8 is the proximal end of the
center post 6. The stem of the center post 8 physically closes the
outlet 17 when it is in interfering engagement with the outlet 17.
The stem of the center post 8 is in interfering engagement with the
outlet 16 when the spout 5 is in its downward or distal most
position.
[0112] End Cap
[0113] The end cap 7 is situated at the distal end of the product
chamber 3 in an inactivated state. In some embodiments, the end cap
7 has a proximal top, peripheral radial edge and distal end.
[0114] In some embodiments, the proximal top of the end cap 7 is in
mating engagement with the distal end of the center post 6 as
exemplified in FIGS. 3 and 6. In some embodiments, mating
engagement of the center post 6 and end cap 7 maintains axial
alignment of the center post 6 within the product chamber 3 and
facilitates movement of the end cap 7 for release of one or more
ingredients, formulations or products. In some embodiments, the
proximal top comprises a proximally situated recess or center post
receiving portion 10 (FIGS. 3 and 6). The end cap 7 is configured
to receive the distal end of the center post 6 in the center post
receiving portion 10. In some embodiments, there are one or more
radial protrusions in the center post receiving portion 10 for
sealing engagement. In other embodiments, as exemplified in FIGS. 3
and 6, the distal end of the center post 6 is configured to receive
the proximal end of the end cap 7. In one embodiment there is
center post mating column located on the proximal end of the end
cap 7. In some embodiments, the center post mating column is
configured to mate with the inner diameter of the distal end of the
center post 6.
[0115] In some embodiments, the peripheral radial edge of the end
cap 7 is in interfering engagement with the inner diameter of the
side walls of the product chamber 3. The interfering engagement is
sufficient to provide sealing integrity alone and maintain the one
or more ingredients, formulations or products in the product
chamber 3 of the base 1 until actuation of the dispenser. In some
embodiments, the peripheral radial edge of the end cap 7 and inner
diameter of side walls of the product chamber 3 are made of highly
polished radial mating surfaces 11. These highly polished radial
faces 11 when in intimate contact provide superior seal integrity
against moisture and maintain product integrity. In some
embodiments, the end cap 7 is comprised of propylene and/or
ethylene materials.
[0116] Upon application of a force upon the center post 6, the
center post 6, moving axially in a downward or distal direction,
moves the end cap 7 in the downward or distal direction below or
distal to the distal end of the product chamber 3. Distal movement
of the end cap 7 reveals a dispensing port 58 at the distal end of
the product chamber 3. In the inactivated state (i.e., prior to
point-of-use dispensing of stored one or more ingredients,
formulations or products) the end cap 7 closes the distal end of
the product chamber 3. In the actuated state (i.e., after
point-of-use dispensing of stored one or more ingredients,
formulations or products), the distal end of the product chamber 3
is an open dispensing port 58.
[0117] In some embodiments, the proximal top of the end cap 7
further comprises a tapered end cap surface 9 also referred to as
seal shoulder 9. The downward angled tapered end cap surface 9
facilitates dispensing of the one or more ingredients, formulations
or products of the product chamber 3 into the receiving vessel.
[0118] In some embodiments, the end cap 7 can be configured to
include a liner in between the distal end of the center post 6 and
the proximal surface of the center post receiving portion 10 in
mating engagement with the distal end of the center post 6. The
liner can provide a sealing interface and added removal resistance.
In some embodiments, a small foil disc with materials coated on the
outside can be cut and placed into the bottom of the proximal
center post receiving portion 10 of the end cap 7 formed to accept
the center post 6. In some embodiments, the liner welds to both
portions, the end cap 7 and the center post 6 at the center post
receiving portion 10 using an RF (radio frequency) sealing process
common in the foil liner applications. Welding with this type of
liner has several advantages (i) the strength of the weld is very
strong such that the end cap 7 cannot be readily separated from the
center post 6; (ii) the weld is more targeted (than spin welding,
sonic welding and heat stake welding), thus avoiding adhering other
nearby portions of the device like the outer portions of the end
cap 7 to the base 1.
[0119] In some embodiments, the distal end of the end cap 7
comprises a distal annular edge. In some embodiments, the distal
end of the end cap 7 further comprises a flat end surface. In some
embodiments the distal end of the end cap 7 is configured to have
one or more distal recesses 33 as illustrated in FIG. 7. The one or
more distal end cap recesses 33 can provide a space for any
residual plastic from the molding process to remain out of the way
and alleviate risk of the residual plastic puncturing the end plate
seal (as described below) if provided. In some embodiments, the
distal end cap recesses 33 are situated centrally, flank the center
post receiving portion 10, and/or a combination thereof.
[0120] In another embodiment, the center post receiving portion 10
comprises two distally located spaces 34 (FIG. 7). These spaces are
provided to receive center flash resulting from the molding process
of the closure device. The center flash spacing 34 retains the
center flash so to avoid interference with, the mechanics of the
closure device, and end cap 7 placement helping to maintain proper
axial alignment.
[0121] In some embodiments, the center post 6 and end cap 7 are
configured in dimension such that the end cap 7 is flush with the
distal end of product chamber 3 in the inactivated state. In other
embodiments, the center post 6 and end cap 7 are configured in
dimension such that the end cap 7 sits proximal to the distal end
of product chamber 3 in the inactivated state (FIG. 7). The later
embodiment is useful for closure devices comprising an end plate
seal (as described below). In some embodiments, the end cap 7 in a
non-flush more proximal position to the distal end of the base 1 in
the inactivated state improves the radial seal of the end plate
seal (as described below) to the distal annular edge of the base
and/or product chamber 3. It ensures that the end plate seal will
attach properly to the distal annular edge of the base 1 and avoids
end plate seal contact with the end cap 7 itself and avoids sealing
the end cap 7 to the base 1. In other embodiments, the end cap 7
together with the distal end of the base 1 and/or product chamber 3
protrudes beyond the distal annular edge of the closure skirt
4.
[0122] End Plate Seal
[0123] In some embodiments an end plate seal is used to provide a
protective seal at the distal annular edge of the product chamber
3. The end plate seal extends across the distal end of the product
chamber 3. The end plate seal is sealed at the distal annular edge
of the product chamber 3. The end plate seal may be made from a
variety materials that are thin and frangible in nature to shear or
fracture upon application of a force. In some embodiments, the
center post 6 engaging the end cap 7 applies force against the end
plate seal causing the end plate to shear and fracture. In some
embodiments a foil liner is applied at the distal end of the end
cap 7 and distal end of the product chamber 3 to seal the interior
of the base 1. In some embodiments, the closure created by the end
plate seal is used to add to product efficacy and provide tamper
evidence if prematurely breached.
[0124] In other embodiments, a foil end plate seal is supported by
plastic across the entire face of the foil to provide sufficient
mechanical support to pass common shipping, filing and drop tests
and to maintain product integrity. Use of a supporting plastic also
allows for a majority of the foil to be intimately attached to the
material used to mold the closure device components, such as
polypropylene (PP) and high density polyethylene (HDPE) polymers,
thereby reducing the amount of foil particulates falling into the
receiving vessel upon dispensing the contents of the product
chamber 3. In some embodiments, the plastic lining also reinforces
the seal for purposes of ingredient freshness and product
integrity.
Spout
[0125] The closure devices of the present invention comprise a
spout 5 for dispensing the product for consumption. In some
embodiments, the spout 5 comprises an outlet 17. Other embodiments
and details of the components and features of the spout 5 of the
present invention are described below.
[0126] In some embodiments, the spout 5 is capable of moving
axially in downward and upward directions. In some embodiments, the
spout 5 is moved by pulling forces to open the spout 5 pushing
forces to close the spout 5. In other embodiments the spout 5 is
moved by rotation, wherein one or more helical elements on the
spout and/or sleeve cooperate to move the spout in an upward and
downward direction relative to the sleeve depending on whether the
spout is being opened or closed. Application of a user-actuated
rotating/twisting or pulling force applied to the spout 5, moves
the spout 5 in an upward direction toward the proximal end of the
closure device. The upward movement of the spout 5 concomitantly
causes the stem of the center post 8 to break the seal with the
sealing member 21 and expose the outlet 17 of the spout.
Application of a user-actuated rotating/twisting or pushing force
will move the spout in the down, distal direction, closing the
spout.
[0127] In some embodiments, in the inactivated and actuated states,
the spout 5 interferingly engages the outer diameter of the side
wall of the spout seal portion of the sleeve 18. In some
embodiments, the one or more inner diameters of the side walls of
the spout 5, e.g., the lesser diameter of the spout 27
interferingly engages the one or more outer diameters of the side
wall of the spout seal portion of the sleeve 18. In some
embodiments, the inner diameter of the side walls of the lesser
diameter of the spout 27 are threaded, the outer diameter of the
side walls of the spout seal portion of the sleeve 18 are threaded,
or both are threaded. In some embodiments, the one or more inner
diameters of the side walls of the lesser diameter of the spout 27
comprise one or more distal end spout beads 20. The one or more
distal end spout beads 20 interferingly engage the outer diameters
of the side walls of the spout seal portion of the sleeve 18 to
provide a leak free seal. In some embodiments the one or more outer
diameters of the side walls of the spout seal portion of the sleeve
18 further comprise one or spout seal beads 19. The one or more
spout seal beads 19 interferingly engage the inner diameters of the
side walls of the spout, e.g., the lesser diameter of the spout 27
to provide a leak free seal. In some other embodiments there is a
combination of one or more spout seal beads 19 and one or more
distal end spout beads 20. In one embodiment, the distal end spout
bead 20 is situated distally to the spout seal bead 19. When the
spout 5 is in its activated and proximal most position, the one or
more distal end spout bead 20 interferingly engage the spout seal
bead 19. When the spout 5 is in its closed state and downward or
distal most position, the one or more distal end spout beads 20 do
not engage the one or more spout seal beads 19.
[0128] In some embodiments, the closure device of the present
invention comprises a pull open spout. Some embodiments with a pull
open spout are shown in FIGS. 3 and 6. The spout 5 is pulled up or
vertically in the proximal direction to open the spout outlet 17
for consumption. The spout outlet 17 may be closed by pushing the
spout down or in the distal direction. The spout outlet 17 may be
opened and closed multiple times.
[0129] In one embodiment, there is a pull open spout comprising a
greater diameter of the spout 24, a lesser diameter of the spout
27, and an outlet 17. In some embodiments, the spout is configured
with a proximally located outlet 17 which is capable of receiving
the stem of the center post 8. In some embodiments, after
dispensing the one or more ingredients, formulations or products of
the product chamber 3 into a receiving vessel, the stem of the
center post 8 is substantially flush with the proximal top of the
spout 5 and in interfering engagement with the outlet 17, thereby
closing the spout. After dispensing, axial or vertical movement of
the spout 5 in the upward direction disengages the stem of the
septum 8 from the outlet 17 and opens the spout. Axial or vertical
movement of the spout 5 in the downward direction re-closes the
spout such that the stem of the center post 8 is in interfering
engagement with the outlet 17 again. In some embodiments, the spout
comprises a sealing member 21 that facilitates closure of the spout
5 to create a high integrity seal.
[0130] In some embodiments, the proximal top of the spout 5 can be
flat or angled. In some embodiments the proximal top of the spout 5
has a greater diameter than the side walls of the spout that are
more distal to the outlet 17. The greater diameter of the proximal
top of the spout 24 can make it easier for an end user to grasp the
spout 5 to pull it open. In other embodiments the proximal top of
the spout has substantially the same diameter as the side walls of
the spout portion that engages the sleeve 12.
[0131] The one or more side walls of the spout 5 have one or more
inner and outer diameters. The one or more inner diameters of the
side walls of the spout 5 interferingly engage the one or more
outer diameters of the side walls of the sleeve 12. In some
embodiments, the one or more inner diameters of the side walls of
the spout 5 are threaded, the one or more outer diameters of the
spout seal portion of the sleeve are threaded, or the combination
is threaded. In some embodiments, the one or more inner diameters
of the side walls of the spout 5 further comprise one or more
distal end spout beads 20. The one or more distal end spout beads
20 interferingly engage the outer diameters of the side walls of
the spout seal portion of the sleeve 18 to provide a leak free
seal. In some embodiments, the one or more outer diameters of the
side walls of the spout seal portion of the sleeve 18 further
comprise one or more spout seal beads 19. The one or more spout
seal beads 19 interferingly engage the inner diameters of the side
walls of the spout to provide a leak free seal. In some
embodiments, there is a combination of one or more spout seal beads
19 and one or more distal end spout beads 20. In one embodiment a
distal end spout beads 20 is situated distally to a spout seal
beads 19. When the spout 5 is in its upward or proximal most
position, the one or more spout seal beads 19 interferingly engage
the one or more distal end spout beads 20 to stop further upward
movement of the spout 5.
[0132] In some embodiments, the side walls of the spout 5 further
comprise one or more radial protrusions. The one or more radial
protrusions are used to make it easier for an end user to grasp the
spout for pulling open and pushing close the spout.
[0133] Outlet
[0134] The outlet 17 is an opening through which contents of a
receiving vessel move through for consumption by an end user. In
some embodiments, the outlet 17 sits in the proximal top of the
spout 5. In some embodiments, the outlet 17 comprises an inner
radial edge. In some embodiments, the outlet 17 is capable of
receiving and engaging the stem of the center post 8. In some
embodiments, the inner radial edge of the outlet 17 interferingly
engages the outer diameter of the stem of the center post 8. The
outer diameter of the stem of the center post 8 engages the inner
radial edge of the outlet 17 to close the outlet 17. When the stem
of the center post 8 is disengaged from the inner radial edge of
the outlet 17 there is an opening connecting the product chamber 3
to the outlet 17 to allow contents of a receiving vessel to be
consumed.
Dust Cover
[0135] The closure device of the present invention comprises a dust
cover 2. In the inactivated state, in some embodiments, the dust
cover 2 covers the spout, sleeve and portions of the base. In some
embodiments, the dust cover comprises one or more dust cover
helical thread forms 13 which engage one or more sleeve helical
thread forms 14. Rotation or twisting of the dust cover drives the
sleeve and end cap in a downward direction, from the closed
position to an open position, resulting in release of the contents
of the product chamber into a receiving vessel. In some
embodiments, the dust cover 2 can then be removed from the base. In
some embodiments, the spout 5 can be pulled open (or
rotated/twisted) by a user so that the combined contents of the
receiving vessel can be emptied through the spout 5.
[0136] In some embodiments, the dust cover is held in position on
the closure by a series of lug 56 and groove 57 combinations
configured to move/work in combination with the sleeve 12 such that
the dust cover is not readily removed from the base until
appropriate lug 56 and groove 56 combinations are aligned.
Referring to FIGS. 5 and 6, in some embodiments, a dust cover lug
element 56 can be located at the distal end of the dust cover 2
which can engage with a groove element 57 located on the deck of
the base 1. In some embodiments, the alignment of the dust cover
lug element 56 and the dust cover groove element 57 and the radial
movement required to make the dust cover 2 align for removal drives
the sleeve 12 and end cap 7 from the closed position to the open
position. The dust cover lug 56 and cooperating groove sequence 57
in the base portion do not allow a user access to ingredients prior
to their release from the product chamber 3 past the end cap 7 into
an appropriate receiving vessel.
[0137] In some embodiments, the dust cover comprises elements that
allow it to be easily grabbed and/or twisted. In some embodiments,
one or more outer gripping lugs 26 can be spaced around the dust
cover 2, as shown in FIG. 2.
[0138] In some embodiments, the distal end of the dust cover 2
engages the deck of the base 2. In some embodiments, a rim feature
29 on the closure skirt deck 35 is positioned at the outer diameter
of the dust cover 2. In some embodiments, the rim feature 29 helps
to stabilize the dust cover 2 and properly align it on the closure
device.
Receiving Vessel
[0139] In some embodiments, the closure devices of the present
invention are configured to attach to and provide sealing
engagement to a variety of receiving vessels. The receiving vessel
may be any container, receptacle, vessel of varying size and shape
capable of being attached to the closure devices of the present
application. It may be constructed from glass, plastic or other
similar material. In some embodiments, the receiving vessel has a
threaded neck for attachment thereto. In some embodiments, the
receiving vessel is attached to a closure device of the present
invention by a manufacturer. In other embodiments, the receiving
vessel is attached to a closure device of the present invention at
the point of use by an end user. In some embodiments, the receiving
vessel has a pliable seal at the land of the vessel opening that
can be removed by an end user at point of use before attachment.
The pliable seal at the land of the vessel opening is used to
maintain product integrity of the receiving vessel. In other
embodiments, the receiving vessel has a removable screw cap or such
other removable top that once removed it is capable of attaching to
the closure devices of the present invention.
[0140] Non-limiting exemplary receiving vessels include bottles,
other beverage containers, cartons, canteens, stand-up pouches,
cans, flasks, glass bottles, and the like.
[0141] The type and form of one or more ingredients, formulations
or products of the receiving vessel is unlimited. Non-limiting
exemplary forms of ingredients of the receiving vessel includes
beverages, drinks, infusions, liquids, shots, suspensions, syrups
and swills. Non-limiting examples of the one or more ingredients,
formulations or products of the receiving vessel include water,
sports drinks, meal replacement beverages, diet beverages, energy
drinks. The receiving vessel may also contain excipients,
acidulants, sweeteners, flavoring agents and coloring agents for
easier consumption by the end-user of a medicament, drug or
pharmaceutical dispensed therein.
Universal Closure Skirt
[0142] In some embodiments, the closure devices described above may
be used in combination with a universal closure skirt to provide
sealing engagement with a variety of container neck finishes and
container opening sizes of a receiving vessel. Universal closure
skirts are disclosed, for example, in WO 2011/057111, which is
incorporated herein by reference. The universal closure skirts
(FIGS. 9-19) of the present invention have a proximal top or deck
35, one or more peripheral side walls 36 and a distal annular edge
37. The proximal top 35 of the closure skirt in one embodiment is
substantially flat and in other embodiments, the proximal top 35
has a slope of varying degrees. In one embodiment, the proximal top
35 of the closure skirt is connected to the side walls 36 of the
closure skirt by an internal rounded corner or fillet radii 38.
FIG. 17 shows the outer annular edge of the fillet radii 38. The
side walls of the closure skirt have an inner diameter 39 and outer
diameter 40. In one embodiment, the inner diameter 39 of the side
walls and the outer diameter 40 of the sidewalls of the closure
skirt are substantially the same along their respective length from
the proximal end to the distal end of the sidewalls 36. In other
embodiments, there are more than one of each of the inner diameter
39 and outer diameter 40 from the proximal end of the side walls 36
to the distal end of the side walls 36 of the closure skirt. The
side walls 36 of the closure skirt are also referred to as the
skirt of the closure device. In one embodiment the side walls 36
are curved to give the closure skirt a generally tubular shape. The
tubular shape of the closure skirt may be conical including any
tapered or multi-sized tubular or cylindrical form. In another
embodiment, the inner diameter 39 of the side walls 36 is curved
and the outer diameter 40 of the side walls 36 is angular.
[0143] In some embodiments, the inner diameter 39 of the side walls
36 of the closure skirt further comprises one or more deformable
depending protrusions 41 of varying dimension to provide a
one-fit-many aspect of the closure devices of the present
invention. In some embodiments, the deformable depending
protrusions 41 are thin, flexible and deformable such that the
closure can accept a variety of threaded neck and opening diameters
and thread profiles. The one or more deformable depending
protrusions 41 provide application and removal torque. In one
embodiment, the one or more deformable depending protrusions
comprise radial rings 42, helix 43 or combinations thereof. In one
embodiment as shown in FIG. 10, the closure skirt has threads on
the internal side walls capable of being rotatably coupled to a
container neck of a receiving vessel. The threads may be of a
variety of configurations and/or helix or pitch. In some
embodiments, the helix has a pitch from about 0 degrees to about 10
degrees. In other embodiments the helix has a pitch greater than 0
degrees to about 4 degrees. In another embodiment, the one or more
deformable depending protrusions 41 comprise more than one axial
rib including vertical ribs 44, angled ribs 45, arced ribs 46,
various other shapes or geometries, or combinations thereof. In
other embodiments the one or more deformable depending protrusions
41 comprise more than one radial rib, including horizontal ribs,
angled ribs, arced ribs, various other shapes or geometries, or
combinations thereof. In other embodiments, the deformable
depending protrusions comprise a combination of radial rings,
helix, axial ribs or radial ribs.
[0144] The deformable ribs (e.g., 44, 45, 46) are placed in
separation on the inner diameter of the side walls to provide
application and removal torque. The axial ribs are compliant
through their vertical length and will shear readily from the top
wall to provide a hinged deformable member with the side wall of
the closure. The axial ribs are attached to the underside proximal
top end of the closure for manufacturing purposes. The axial ribs
are designed in such a manner that the proximal end tears or breaks
away from the closure when the closure is being applied to a
container. Attachment at the underside of the proximal top 35 is in
one embodiment sharp such that is there is no fillet radii. In
another embodiment, there is a small fillet radii where the side
walls 36 meet the underside of the proximal top 35 as long as it
will not interferingly engage with the neck or opening of a
receiving vessel when the closure is applied.
[0145] In some embodiments, the depth of a deformable depending
protrusion from the side wall can range from about 0.005 to about
1.0 inches. In one embodiment, the depth from the side wall is
about 0.040 inches. In some embodiments, the thickness of an axial
rib is from about 0.005 inches to about 0.050 inches. In one
embodiment, the thickness of the axial rib is about 0.020
inches.
[0146] In another embodiment, the universal closure skirt comprises
a proximal top 35, one or more peripheral side walls 36, a distal
annular edge 37 and a depending plug seal 47. The inner diameter 39
of the side walls 36 is non-threaded and has no deformable
depending protrusions of varying dimensions 41-46. In other
embodiments, there is more than one spacer rib, and/or more than
one thread engagement lug, each as described below.
[0147] Plug Seal
[0148] As shown in FIG. 8 the closure skirt in some embodiments
also comprises a depending radial flexible plug like sealing member
47 that fits to the inner diameter of a receiving vessel neck. This
plug seal 47 is unique in its configuration such that it provides
sealing engagement opportunities to a multiplicity of neck finish
inner diameters. As shown in FIG. 8, the plug seal protrudes inside
the opening of a container keeping its contents secure from
leakage. The plug seal 47 is designed to have interfering
engagement with the inner diameter of the opening of a container
neck such that it seals the contents of the container from leaking
out and still allows sufficiently low application and removal
forces to be readily applied and removed by the end user.
[0149] The plug seal depends from the underside of the proximal top
35 of the closure. The dimensions of the plug seal 47 may vary. In
some embodiments, the plug seal 47 has a longer and thinner lower
or distal lead in section 48 that can be readily folded or deformed
out of location providing interfering engagement for larger inner
diameter bottles and a thicker upper or proximal radial sealing
section 49 for smaller inner diameter bottles. In some embodiments,
the plug seal 47 has a smaller diameter at its distal end with
increasing diameter moving toward the deck or proximal top of the
closure skirt. The configuration of the plug seal 47 can be
bean-shaped, angular or other shapes and geometries to provide
interfering sealing engagement for container necks with openings of
a smaller inner diameter at the lower distal end of the plug seal
and interfering sealing engagement for container necks with
openings of a larger inner diameter at the upper proximal end of
the plug seal.
[0150] In another aspect, the present invention provides an
improved plug seal shape that facilitates manufacturing. Viewed in
cross section of FIG. 8, the plug seal is angled in shape, such
that the apex 50 of the angle interferingly engages the inner
diameter of a container neck. The proximal end 49 is larger than
the distal end 48. The plug seal's angled surface (viewed in cross
section) interior portion is not parallel to the outer sealing
profile. The inside surface of the improved plug seal has an
interior shape that tapers away from outer surface. These differing
tapers allow the intended angular shape to be ejected from the
cavity forming steel without the need for additional steel movement
for ejection from cavity forming steel. The improved angular shape
of the plug seal eliminates the need for floating steel components
to release the undercut from the mold, yet provides interfering
radial engagement to the inner diameter of the neck of a receiving
vessel to maintain proper seal integrity. The improved plug seal
may be used in combination with the disclosure devices of the
present invention in addition to other dispensing closure
devices.
[0151] In some embodiments, the length of the plug seal from its
proximal end to the distal end is substantially the same length as
the side walls of the closure skirt 36 such that the distal edge of
the internal closure diameter is substantially flush with the
distal annular edge of the side walls. In other embodiments, the
length of the plug seal 47 from its proximal end to the distal end
is less than that of the side walls of the closure skirt 36.
[0152] In some embodiments as shown in FIG. 8, the plug seal 47
creates an internal spacing diameter 51 that allows the plug seal
to bend and conform to varying container neck finishes and
diameters. The internal spacing diameter 51 spans from the inner
diameter of the plug seal to the outer diameter of the base housing
2 within the closure side walls 36. The width of the internal
spacing diameter 51 may vary to provide interfering engagement with
varying inside diameters of container necks.
[0153] In another embodiment, there is a plurality of sealing beads
at varied positions on the plug seal. In some embodiments, the
sealing beads are radial bumps that interferingly engage the inner
diameter of the opening of a container to close the opening. In
some embodiments, the sealing beads can be positioned at various
locations and of varying sizes to engage the neck or opening of a
container of various sizes. In one embodiment, the sealing beads
are of a smaller size at the distal end of the plug and increase in
size moving toward the proximal top of the seal plug. The sealing
beads work such that if a closure does not go all the way down to
engage the top of the neck or opening of a container, then a set of
sealing beads engage the internal diameter of the opening or neck
of a container to create a seal and close the opening. In one
embodiment, the smaller and more distal sealing beads will engage
the inner diameter of smaller openings and the larger more proximal
sealing beads engage the inner diameter of larger openings.
[0154] Spacer Rib
[0155] As shown in FIGS. 9-18, the universal closure skirt may
further comprise more than one spacer rib 53 used to provide
interfering engagement without increasing radial torque. The spacer
ribs 53 are connected to the inner diameter 39 of the side walls 36
of the closure skirt and in one embodiment diametrically opposed
which allows the thread to fit in between the protrusions 41-46
allowing the closure skirt 4 to conform to an oval shape. In other
embodiments, the spacer ribs are spaced apart from each other. The
vertical position of the spacer ribs on the inner diameter is
important to provide vertical interference with the outer diameter
of the container neck finish thread. The spacer ribs 53 in one
embodiment are situated to mate with the inside proximal top 35 of
the closure skirt 4. In another embodiment, the spacer ribs 53 are
situated below the proximal top 35. In some embodiments, the width
of a spacer rib 53 is in the range of about 20 mm to about 28 mm
for closure devices fitting about 26 mm to about 28 mm container
neck or opening sizes. The length of a spacer rib 53 should be in
the range of about 2 mm to about 20 mm for closure devices fitting
about 26 mm to about 28 mm container neck or opening sizes. For
larger diameter container neck or opening sizes there are, in some
embodiments, larger dimensioned spacer ribs. In some other
embodiments, there are more than two spacer ribs for larger
diameter container necks or opening sizes. As the size of the
container neck increases, more spacer ribs provide more
interference with the container neck to secure the universal
closure skirt and to prevent the closure from disengaging upon
shaking
[0156] Thread Engagement Lug
[0157] As illustrated in FIGS. 18 and 19, the universal closure
skirt may also comprise more than one thread engagement lug 54 used
to meet and provide interfering engagement with a variety of thread
configurations and helix of varying pitch of the container neck
engaged by the universal closure skirt. The thread engagement lugs
54 are connected to the inner diameter 39 of the side walls 36 of
the closure skirt and in one embodiment diametrically opposed. In
other embodiments, the thread engagement lugs 54 are spaced apart
from each other. The radial spacing between the thread engagement
lugs allows the closure skirt 4 to deform during application to a
container neck. The vertical and radial positions of thread
engagement lugs are defined such that they will engage threads on a
variety of neck finishes within a range. The thread engagement lugs
can be in horizontal alignment or off set vertically and radially
to provide optimal thread to neck finish engagement. For larger
diameter container neck or opening sizes there are, in some
embodiments, larger dimensioned thread engagement lugs. In some
other embodiments, there are more than two thread engagement lugs
for larger diameter container necks or opening sizes. As the size
of the container neck increases, more thread engagement lugs
provide more interference with the container neck to secure the
universal closure skirt and to prevent the closure from disengaging
upon shaking
[0158] FIG. 18 shows the thread engagement lug 54 in radial
alignment with the spacer rib 53 on the inner diameter of the
universal closure skirt. The spacer rib however occupies different
vertical space from the thread engagement lug. The spacer rib 53 is
more proximal in relation to the position of the thread engagement
lug 54 which is more distally situated. In other embodiments, the
thread engagement lugs are not radially aligned with the spacer
ribs, and appear in overlapping or alternating positions along the
radial inner diameter while still maintaining different vertical
space. The radial spacing between the thread engagement lugs and
the spacer ribs allows the closure skirt 4 to deform during
application to a container neck.
[0159] Spacing Diameter
[0160] In some embodiments, the universal closure skirt comprises a
spacing diameter 51 that provides clearance for the neck of a
container engaged by the universal closure skirt. The spacing
diameter allows for the plug seal to move as needed for a proper
fit. The spacing diameter spans from the inner diameter 4 of the
sidewalls 36 of the closure skirt to the outer diameters of the
plug seal 47. For larger diameter container neck or opening sizes,
in some embodiments, the spacing diameter is larger sized.
[0161] Thinning Ribs
[0162] As illustrated in FIG. 19, in some embodiments, the
universal closure skirt comprises one or more thinning ribs 55 to
add flexibility to the side walls 36 of the closure skirt. Added
flexibility in the skirt allows the closure to conform to larger
container neck diameters and conform to oval shaped container neck
diameters. The thinning ribs 55 may be axial, radial, angled,
arced, various other shapes or geometries, or combinations thereof.
The thinning ribs 55 comprise one or more areas of the outer
diameter 40 of the side walls of the closure skirt where the side
wall material is thinned enough to provide flexural deformation of
the closure skirt when interference with the spacer ribs is created
during application to the threaded container neck.
[0163] Foil Seal
[0164] In yet other embodiments, the closure skirt of the present
invention comprises a distal foil seal to provide sterility to the
inside of the closure skirt and underside of the closure housing.
The foil seal spans across the outer most and distal most diameter
of the closure device.
[0165] Container Openings and Neck Finishes
[0166] The closure skirt can be designed to fit a variety of neck
finishes, thread profiles and container opening sizes of various
containers/receiving vessels. The container may have a neck or
other suitable structure defining the container mouth or opening.
The neck may have a circular cross-sectional configuration or some
other configuration like an oval or other elliptical, angular
cross-sectional shape. The universal closure skirt may be
configured to provide sealing engagement with container necks of
varying dimension. In some embodiments, the universal closure skirt
is configured to provide sealing engagement with container necks
having a diameter from about 10 mm to about 45 mm.
Tamper Evident and Protective Components
[0167] It is another aspect of the present invention to provide
closure devices as described above that indicate to the end user
whether inadvertent release of stored one or more ingredients,
formulations or products has occurred and that protects the user
from accidental, inadvertent or premature dispensing.
Tamper Evident Bands
[0168] In some embodiments of the closure devices of the present
invention, the closure skirt 4 has a frangible tamper evident (TE)
band removably attached to its distal annular edge 37 that
interferingly engages with the neck of an attached receiving vessel
to prevent removal of the closure device. In one embodiment, there
is a pull tab that when pulled breaks the TE band away from its
engagement with the closure skirt 4. In another embodiment, the TE
band is attached by one or more break-away tabs such that
application of a twisting motion of the closure skirt 4 in a
counter clock wise direction breaks the TE band away. A TE band
that is not in interfering engagement with the receiving vessel at
point of use is indicative of tampering. The closure skirt 4 can be
used with or without the depending tamper evident skirt band.
[0169] In some embodiments of the closure device, the closure
comprises a frangible spout TE band removably attached to the
spout, such as the distal annular edge of the spout 5. In some
embodiments, the spout TE band can interferingly engage a radial
bead on the sleeve and/or spout. In some embodiments, the spout TE
band surrounds the sleeve 12 to prevent inadvertent or premature
upward pulling of the spout 5. In one embodiment, there is a pull
tab that when pulled breaks the spout TE band away from its
engagement with the sleeve and/or spout.
[0170] A removed spout TE band or a spout TE band that is not in
interfering engagement with the distal end of the spout 5 at point
of use is indicative of tampering.
[0171] TE bands can also be attached to the dust cover 2 to prevent
inadvertent actuation. The TE bands can be configured with a pull
tab which can be removed prior twisting and/or removal of the dust
cover 2.
