BACKGROUND
Field ofthe Disclosure
The disclosure relates to a closure for a product retaining container. Moreover,
the disclosure relates to a closure system, a liner for a container closure and to a method of
manufacturing said closure and said liner.
Technical Background
In view of the wide variety of products that are dispensed from ners,
numerous constructions have evolved for ner closures, including, for example, screw
caps, stoppers, corks and crown caps, or the like. Generally, ts such as vinegar,
vegetable oils, laboratory liquids, detergents, honey, condiments, spices, alcoholic beverages,
and the like, impose similar ements on the type and construction of the closure means
used for containers for these products. However, wine sold in bottles represents the most
demanding product in terms of bottle closure technology, due to the numerous and
burdensome requirements placed upon the closures used for wine bottles. In an attempt to
best meet these demands, most wine bottle es or stoppers have historically been
produced from a l material known as "cor ".
While natural cork still remains a dominant material for wine closures, synthetic
wine closures have become singly popular over the last years, largely due to the
shortage in high quality natural cork material and the problem of wine spoilage as a result of
“cork tain ”, a enon that is associated with natural cork materials. In addition, next to
synthetic cork stoppers, there has recently been a growing ance and use of screw caps
as closures for wine bottles. These caps are particularly advantageous due to their relatively
low cost, the avoidance of "cork taint" with this type of bottle closure, and the possibility to
achieve an airtight, hermetic seal.
Most screw caps contain a liner so as to achieve a substantially airtight,
substantially hermetic seal between the closure and the bottle. Such a seal prevents
substantially any oxygen transfer through the bottle closure. For certain types of wines,
ally white wines, conventional air-tight screw-caps may be the closure of choice, as
ingress of oxygen impairs the fresh and fruity appeal of these wines, which are usually meant
to be consumed young. However, for other types of wines, such as premium class red wines,
it is desirable to strike a delicate balance between tightly sealing the bottle content to prevent
. leakage, avoid contaminants, counteract degradation and spoilage by oxidation, on the one
hand, and, on the other hand, permitting a restricted amount of oxygen to enter the container,
so as to ensure full maturation of the wine flavor characteristics and prevent the formation of
unpleasant aromas. Recent scientific studies appear to confirm what was already accepted
empirical knowledge in the traditional art of Winemaking: that oxygen is tely involved
in the aging and maturation s of wine. If certain types of wines are completely starved
of oxygen for long s of time, a process known as reduction may give rise to
malodorous sulfur compounds such as certain sulphides, thiols and mercaptans. To prevent
reduction over the entire period of wine aging and maturation, a minute but constant
concentration of oxygen within the container interior is necessary. The olfactory defect
occurring otherwise is sometimes referred to as reduced character and can be readily '
identified by the presence of odors reminiscent of rotten egg, garlic, nt water, burnt
rubber, struck matches and/or cooked cabbage. Even at low trations, these odors may
completely ruin a wine's character.
Therefore, bottle es that ensure a hermetic seal, such as crown or screw
caps, are usually not recommended for bottling of wines which require a certain amount of
oxygen (from an organoleptic point of View) to diffuse into the interior of the closed bottle.
This is the reason Why l cork stoppers - and not screw caps - have been used as closures
of choice by many tions of kers. Conventional screw caps on the other hand,
are used preferentially for bottling wines that are ed for more immediate ption,
in which this aging period is not required or desired. As mentioned hereinbefore, the use of
hermetic, airtight closures for wines intended for long periods of aging in the bottle may give rise to
reduction processes, which may compromise the organoleptic properties of the wine.
To be able to leverage the advantages of using screw caps also when closing higher quality
wines, which need limited oxidation for full leptic maturation, closure logy has been
developed that allows for controlled ingress of oxygen through microperforated screw cap liners. The
total amount of oxygen that the bottled wine will be exposed to depends on the elapsed time period
before consumption. There may be a great degree of variation depending on whether the Wine was
consumed early after bottling or was stored for several years before consumption. Moreover, the
method of manufacturing said microperforated breathable screw cap liners is quite labor— and cost—
intensive.
There is a need for closures with a defined amount of oxygen being ed to the bottle
content without running the risk of spoilage by either uncontrolled oxidation or complete lack of
oxygen, i.e., reduction.

ED DESCRIPTION
By referring to Figures 1 to 15, along with the following detailed disclosure, the
construction of the closure of the certain embodiments disclosed herein can best be
understood.
In these Figures, as well as in the following detailed disclosure, the e of
various ones of the embodiments is depicted and discussed as a bottle closure for wine
products. However, the various embodiments can be applicable as a e for use in
g and retaining any desired product in any desired closure system. Due to the stringent
and difficult demands and requirements placed upon closures for wine ts, the
following detailed disclosure focuses upon the applicability of the synthetic bottle closures as
a closure for wine bottles. Nevertheless it is to be understood that this detailed sion is
provided merely for exemplary purposes and is not intended to limit the embodiments
disclosed herein to this particular application and embodiment.
Embodiments disclosed herein e for a closure for a t retaining
container wherein the e comprises an oxidant ing agent. rmore,
embodiments disclosed herein provide for a closure for a product retaining container wherein
the closure comprises a gas containing reservoir, a membrane and a barrier layer, said
membrane allowing an at least partial exchange of gas between the inside of said reservoir
and the inside of said container, and said barrier layer at least partially preventing exchange
of gas between the outside of said closure and the inside of said reservoir.
Embodiments disclosed herein provide for closures for containers. In one
embodiment, the closure comprises an oxidant releasing agent. Such oxidant may, for
e, be oxygen, in which case the oxidant releasing agent may, for example, be a
peroxide nd that is able to release oxygen. ing to another embodiment, the
PCT/EP20121054084
amount of the oxidant releasing agent may be selected so as to achieve a defined e of
oxidant over a defined period of time.
While the closure may, in principle, relate to any kind of closure, due to the
special requirements in the wine industry, the closure of the present disclosure is particularly
useful as a closure for wine bottles such as, for example, a natural or synthetic cork
stopper or
a screw-cap closure. An alternate embodiment includes a bag in a box wine container such
where the liner of a bag in a box wine container ns an oxidant releasing
agent.
As used herein the term “product retaining ner” is meant to include bottles,
jars, flasks, canisters, tins, vials and the like. In an exemplary embodiment, the product
retaining container is a wine bottle. The term “closure” as used herein applies to
any means
for effectively closing product retaining containers in l. Such closures include, but are
not limited to, screw caps, stoppers, corks, crown caps, latches, seals and lids. ing to
one embodiment, the closure is selected from the group consisting of a bottle
cap, such as a
screw cap or a crown cap, and a cylindrically shaped bottle stopper. es for screw caps
include, but are not limited to, roll-on pilfer proof screw caps (“ROPP”) and roll-on tamper
evident screw caps (“ROTE”). According to an embodiment, the material for the closure
may, for e, be selected from the group consisting of metal, r material, glass,
natural materials such as cork, ceramic, steel, and rubber and combinations thereof.
{0038] According to an exemplary ment, the closure may, for example, be a screw
cap closure. Screw cap closures typically comprise a cap having interior threads adapted to
interoperate with exterior threads on a container opening (e.g., on the upper opening of a
). In addition, the cap closures typically comprise a seal. The or threads of the
may, for example, be formed by pressure forming the cap (e.g., a cap made from aluminum
metal) onto the exterior threads on the container g (e.g., on the opening of a bottle
during the bottling s). Materials for and methods of manufacturing a screw
cap closure
are known to the person skilled in the art and, for example, described in US Patent No.
6,403,173 B1 , which is hereby incorporated herein by reference in its entirety. Referring now
to Figures 1 and 2, a screw cap closure 10 adapted to fit on a wine bottle 12 is illustrated. in
this embodiment, the wine bottle 12 includes threads 14 on an upper opening as is well
understood. The screw cap closure 10 includes an outer metal cap 16 having a head 18 and a
skirt 20, a ed plastic insert 22 having interior threads 24 and adapted to interoperate
with threads 14 of the wine bottle 12, and possibly a seal 26, if the plastic insert 22 does not
W0 201 2/1 20109 PCTI’EP2012/054084
perform the sealing function. An advantage of this type of screw cap closure 10 is that the
outer metal cap 16 is itself not threaded, which improves the aesthetic quality of the cap.
In an alternate embodiment, the closure of the present disclosure may be a natural
or synthetic r. Referring now to Figures 3 and 4 such stoppers 30 may have a
substantially cylindrical shape and ntially flat terminating ends 32, 34. They may be
made of natural cork and/or of polymer material. According to one embodiment, these
stoppers may have a cylindrically shaped core member (not shown) formed from foamed
plastic material and at least one independent layer of foamed or non-foamed plastic material
(not shown) peripherally surrounding and intimately bonded to the core member with the flat
terminating end surfaces 32, 34 of the core member being devoid of said outer layer. Such
tic stoppers are described inUS Patent No. 6,221,451 B1, which is hereby incorporated
herein by reference in its entirety.
The stopper 30 may further e a liner 36, which may be made from a
polymer material. Exemplary commercially available liners such as Saran liners, Saranex
liners, Saran-tin liners or Stelvin liners may form the liner 36. These liners 36 generally
combine multiple layers selected from the group consisting of polymer materials such as
polyethylene, nylidene chloride (PVDC) and laminates thereof, saran film, metal foil
and wadding material such as foamed polymer material or fiber card (paper). According to a
particular embodiment, the liner 36 may include a deformable ite in which the layers
are selected from the group consisting of monolayers or combinations of PVDC, Nylon, filled
Nylon, EAA, EVOH, starch, ose, PET, PP, PE, EVA, PEO, styrene block copolymers,
COC, polystyrene, rbonate and ne and ymers of the above polymers.
According to yet another aspect, the liner 36 may provide for a substantially liquid
and/or gas tight, hermetic seal at the interface n the ner (e. g., wine bottle 12) and
the closure or stopper 30. This may be achieved, for example, by having the liner 36 e
a barrier layer to prevent or reduce permeation of gases through the stopper 30. Such barrier
layer may, for example, be a metal film layer selected from the group consisting of an
aluminum film layer and a tin film layer. Further possible barrier layers may se other
gas-impenneable materials selected from the group consisting of glass, steel, polymeric
materials, PVDC-laminates and the like and also combinations thereof. Liners with such
barrier layers are known in the art as evidenced by US Patent No. 6,677,016 B2, which is
hereby incorporated herein by reference in its entirety.
W0 2012/] 20109
According to another aspect, the oxidant releasing agent may be included in the
liner 36 or the seal 26 described above. Accordingly, embodiments disclosed herein also
relate to a seal 26 having an oxidant releasing agent. As illustrated in Figure 5, the seal 26
may include a metal film layer 40. In the case of a multilayer closure element, the oxidant
releasing agent is entially contained in one of the innermost element or layers 42 facing
the interior of the product ing container. A thin polymer film 44 or the like can be used
to prevent the t releasing agent to come into direct contact with the bottle content.
In r embodiment, liner 36 or sea] 26, which includes the oxidant releasing
agent is selected from the group consisting of the entire closure, an area defining part of the
closure, a liner that can be fitted between container and the remainder of the closure and a
layer defining part of said liner. Furthermore, said element of polymer material may
comprise foamed polymer material.
In an alternate embodiment, the concepts of the present disclosure
may be d
to other wine containers, such as the proverbial “bag in a box” wine container. “Bag in box”
containers lly comprise a flexible bag made of one or several layers of plastic film or
ised film. The bag is ucted for storage of s, such as wine, and is lly
provided with a dispensing unit such as an airtight tap 50 (illustrated in Figures 6 and 7) for
dispensing of the stored liquid. The bag is seated inside a box, typically inside a cardboard
box or inside a corrugated fiberboard box. Tap 50 may be a conventional tap having a spigot
52, dispensing lever 54, and flange 56 disposed outside the box. Plug 58 with ridge 60 may
be disposed inside the box and engage the bag as is well understood. A ring or loop 62
fit around the plug 58. The ring or loop 62 is annular, but otherwise constructed in a fashion
similar to the seal 26 or liner 36 and performs the same function. The ring or loop 62 may
atively be disposed inside the plug 58. Regardless of position, the ring or loop 62
should be in contact with the interior portion of the bag so that the
oxygen releasing agent
within the ring or loop 62 is allowed to interact with the space within the bag. While a ring
or loop 62 is specifically contemplated, the element may take other shapes as needed or
d and still perform the same on.
The oxidant releasing agent may, for example, be a chemical, a catalyst or an
enzyme capable of releasing an oxidant into the interior of the product retaining container. In
a preferred embodiment the oxidant releasing agent should satisfy common food safety
regulations. ing to the embodiments, the oxidant releasing agent may, for example, be
selected from the group consisting of peroxides, superoxides, ozonides, chlorates,
perchlorates, borates, perborates, percarbonates, perphosphates, perpyrophosphates,
persilicates, persulfates, thiosulfates, peroxydisulfates, peroxy compounds, and their salts and
precursors, and combinations thereof. Moreover, said oxidant releasing agent can be selected
from the group consisting of inorganic, organic and polymeric compounds, and combinations
thereof. In another embodiment said oxidant releasing agent is selected from the group
consisting of superoxides and peroxides of alkali metals and alkaline earth metals, and
combinations thereof. In another embodiment said oxidant releasing agent is selected from
the group consisting of potassium superoxides and magnesium superoxides, and
combinations thereof. Furthermore, said oxidant ing agent may, for example, be
selected from the group consisting of peroxycarboxylic acids and sulfcne peroxycarboxylic
acids, and combinations f. Possible further t releasing agents can be nic
or organic oxides and hydroxides such as for example magnesium hydroxide or magnesium
oxide. er, foamed material may constitute the t releasing agent. In another
embodiment the oxidant releasing agent is selected from the
group consisting of catalysts and
enzymes catalyzing reaction releasing oxidant molecules, and ations thereof. In
particular, said catalysts or enzymes may generate ts by conversion of a precursor
substance.
Preferably, the released oxidant itself is selected from the group consisting of
molecular oxygen, hydrogen peroxide and superoxide, and combinations thereof.
According to r embodiment, the t releasing agent releases oxidant
only after exposure to an activator, being substantially inactive prior to this exposure. This
ment allows the oxidant releasing capability of the closure to remain dormant
throughout the bottling process until the oxidant releasing mechanism is triggered by the
activator. According to another ment, said activator may, for example, be selected
from the group consisting of moisture, acidic solution, basic solution, vapor, liquid,
temperature , and light, and combinations thereof. In particular, temperature change
pertains to heat or cold. In yet another embodiment, said activator may be released by the
product contained in the container.
According to yet another aspect, the amount of oxidant releasing agent may be
selected so as to achieve a defined rate of oxidant e from the screw
cap closure 10 over
a defined period of time so as to result in a defined total amount of oxidant released. In
general one or more ments disclosed herein provides a screw cap closure 10
comprising an oxidant releasing agent, which ensures a slow, substantially constant and well
W0 2012/]20109 PCT/’EP2012/054084
defined oxygen release rate over a defined period of time, so as to prevent ion while
maintaining tency. It is expected that the amount of oxidant released will go to zero in
a certain period of time. ingly, in an exemplary embodiment, the amount of oxidant
releasing agent may be selected so as to achieve the oxygen release rate going to zero after a
period selected from the group consisting of 10, 5, 4, 3, 2 years and 1 year. In the case that
the oxidant releasing agent is comprised in an element of polymer material, according to the
ments sed herein, the concentration of oxidant releasing agent in the polymer
material can range from 0.01% by weight to about 10% by weight based on the weight of the
polymer al. Possible other concentrations for the oxidant releasing agent in the
polymer material can range from close to 0.01% by weight to about 5% by weight or 0.01%
by weight to about 2% by weight or 0.01% by weight to about 1% by weight or 0.01% by
weight to about 0.1% by weight based on the weight of the polymer al. There may also
be circumstances where concentrations for the oxidant releasing agent in the polymer
material are desirable that range from close to 0% by weight to about 1% by weight or from
close to 0% by weight to about 0.5% by weight or from close to 0% by weight to about 0.1%
by weight or from close to 0% by weight to about 0.01% by weight based on the weight of
the polymer material.
According to yet another aspect, the amount and type of oxidant releasing agent
may be ed based on the oxygen requirements associated with the wine being closured.
The two types of screw cap liners currently most used in the wine industry are foil/PVDC
laminates and PVDC laminates. Typically, a standard 30 mm diameter foil cap liner, when
well sealed to a bottle, has an oxygen diffusion rate of approximately 0.0002 cc oxygen per
750 mL bottle per 24 hours; Typically, a well sealed 30 mm PVDC cap liner has a diffusion
rate of approximately 0.002 cc oxygen per 750 mL bottle per 24 hours. Recent studies appear
to show that the oxygen diffusion rate of top quality natural cork stoppers falls between that
of the foil and PVDC liner containing screw cap closures. Embodiments disclosed herein
enable winemakers to choose screw cap closures 10 containing oxidant releasing agents that
feature customized oxygen release rates for their closures that fall between these values. A
winemaker bottling a white wine, for instance, may desire a screw cap e 10 according
to an embodiment with an oxygen release rate into the interior of the bottle of imately
0.0005 cc per 750 mL bottle per day. Accordingly, the winemaker may select a screw cap
closure 10 made using the technology having an oxygen release rate in the range of, for
example, about 0.0004 to 0.0006 cc oxygen per screw cap closure 10 per 24 hours. Similarly,
PCT/EP20121’054084
a heavy red wine, which the winemaker wants to age in the bottle, will require more oxygen
and could be capped with a closure 10 having release rates in the range of, for example, about
0.0007 to 0.0015 cc oxygen per bottle per 24 hours. In a further embodiment oxygen release
rates of the closure 10 into the bottle interior can be 0.00005 — 0.002, 0.00005 - 0.001,
0.00005 - 0.0005, 0.00005 — 0.0002, 0.00005 — 0.0001, and 0.0001 - 0.002 cc oxygen or
oxidant per 24h per 750 mL bottle. There may also be circumstances in which oxygen
release rates higher than 0.002 cc oxygen per 750 mL bottle per 24 hours are desirable.
During the bottling process there is a high chance that oxygen is trapped in the
headspace between the bottle content and the closure 10. Moreover, it appears that
immediately after closing wine bottles with natural or synthetic cork stoppers, off—gassing of
air from the compressed cork material r contributes to an initially high local
oxygen
concentration in the bottle interior. To counteract the initially high oxygen tration,
which could lead to rolled oxidation of the wine, a closure 10 may further comprise
oxygen scavenging agents. Said oxygen scavenging agent can effectively antagonize and
decrease the initially high oxygen concentration immediately after bottling. During long term
bottle storage, the t releasing agent present in the closure 10 would nonetheless ensure
a defined amount of oxygen to be consistently released into the container interior over a
defined period of time.
In a further embodiment, the oxygen scavenging agent could also be used to
nize and fine-tune the amount of oxygen present in the bottle, which may have been
actively released by the oxidant releasing agent or may have passively permeated through the
bottle closure. Said oxygen scavenging agent may be contained in an element of the closure
selected from the group consisting of the element of polymer al comprising the oxidant
releasing agent, the entire closure 10, an area defining part of the closure, a seal 26 or liner 36
that can be fitted between container (cg, wine bottle 12) and the remainder of the closure
and a layer defining part of said liner. ing to the other embodiments disclosed herein,
the oxygen ging agent may be contained in the same or in a different element of the
closure 10 than that containing the oxygen releasing agent (e.g., in layer 42 or some other
element). le oxygen scavenger agents are selected from the group ting of
ascorbates, sulfites, EDTA, hydroquinone, tannins and the like, and their salts and precursors,
and combinations f. In a preferred ment, the oxygen scavenger agent is selected
from the group consisting of sodium ascorbate, sodium sulfite and potassium EDTA, iron or
other metal based scavengers, and combinations thereof.
W0 2012/1 20109 PCT/EP20121054084
Embodiments disclosed herein also encompass a closure system comprising a
product retaining container and a closure 10 as defined above, e.g., a wine bottle sealed with
a closure 10 according to the embodiments disclosed herein. Moreover, the embodiments
disclosed herein can specifically include the use of an oxidant-releasing agent containing
closure 10 as described above for ring a ned amount of
oxygen to the or of
a product retaining container over a defined period of time.
The closure can be manufactured by methods known to the person skilled in the
art. Suitable methods of manufacture may comprise the step of introducing an oxidant
releasing agent into a closure 10. In a preferred ment, the manufacturing steps are
selected from the group consisting of coating, spray tion, injection molding, extrusion,
co—extrusion and foaming, and combinations thereof. This is particularly the case when the
oxidant releasing agent is comprised in a liner 36. A method for manufacturing said liner 36
may comprise manufacturing steps being selected from the group consisting of coating, spray
deposition, injection g, extrusion, rusion and foaming, and combinations
thereof. Suitable methods of cturing a liner 36 for wine bottle closures are known to
the person skilled in the art and for example described in detail in previously orated US
Patent No. 6,677,016 B2. A closure 10 can also be manufactured by applying an element of
thin polymer film 44 containing an oxidant—releasing agent to a closure 10 or a n
thereof by means of g, spray deposition, injection molding, extrusion, co—extrusion and
foaming. Accordingly, embodiments disclosed herein also relate to a method of
manufacturing a closure comprising an oxidant-releasing agent.
Examples
[0054} Hereinafter, certain exemplary embodiments are described in more detail and
specifically with reference to the examples, which, however, are not intended to limit the
present disclosure.
Example 1:
Screw Cap containing an oxidant releasing liner
A screw cap e is produced, consisting of a liner 36, an outer metal cap 16
and a surrounding metal skirt 20. The oxidant releasing agent is contained in the liner 36,
which is built up of the ing layers from bottom (facing the contained product) to top
(contacting the lid of the screw cap): A very thin first polymer film layer of low—density
2012/054084
polyethylene (LDPE) 44; a polymer layer 42 containing the oxidant releasing agent; a barrier
layer 40 disposed on said polymer layer 42, that es a nylidene chloride (PVDC)
te in combination with a metal foil (typically aluminum or tin) disposed on the PVDC
layer; fiber card (paper) or polymer foam and a second LDPE polymer film layer. The metal
film of the barrier laminate has a very low oxygen diffusion rate, and thereby prevents
oxygen from diffusing through the cap liner into the bottle and t ned therein.
The oxidant releasing agent in the liner 36 releases in a low but constant rate hydrogen
peroxide into the headspace of the wine bottle 12. The hydrogen peroxide spontaneously
decomposes to free oxygen and water. The thus ted oxygen dissolves into the wine,
where it prevents reduction of the latter and promotes the maturation of the desired wine
flavor characteristics.
Example 2:
tic stopper with oxygen releasing polymer film affixed thereto
{0056] A synthetic wine closure such as r 30 of substantially cylindrical shape
consisting of a foamed polymer core member and an outer skin is produced by means of
coextrusion. In a subsequent step, a thin polymer film 36 containing an oxidant releasing
agent is affixed to the substantially flat terminating ends of the stopper. The thus obtained
closure 30 is used for the bottling of red wines. As these require a period of aging with a
certain amount of oxygen present for the2 full maturation of the wine's flavor characteristics,
the oxygen released by the liner 36 ensures optimal flavor development and prevents the
formation of unpleasant aromas associated with reduction.
The technology described herein is not restricted to es but may also be
d to packages in general. Furthermore, the technology may be incorporated into a liner
associated with the package or incorporated directly into the package. For example, as
illustrated in Figures 8 and 9, a bottle 70 may incorporate the present technology. In Figure
8, the bottle 70 has a sidewall 71 delimiting the interior 72. A liner 73 is positioned within
the interior ’72 and impregnated with the oxygen releasing agent as previously discussed. In
contrast, in Figure 9, the bottle 70 has a sidewall 74 with the oxygen releasing agent
embedded therewithin.
Similarly, the concepts of the present disclosure may be extended to bag in a box
containers. As illustrated in Figure 10, a bag in a box ner 75 may include a sidewall 76
that forms the box. Inside the sidewall 76 is a bag 77. A liner 78 is positioned inside the bag
77. The liner 78 has an oxygen releasing agent nated therein as usly described.
Similarly, Figure ll illustrates an ate ment, wherein the bag 79 is constructed
such that the oxygen releasing agent is embedded directly into the bag.
{0059] In another alternate embodiment the closure may comprise a gas containing
reservoir, a membrane and a r layer, said membrane allowing an at least partial
exchange of gas between the inside of said reservoir and the inside of said container, and said
barrier layer at least partially preventing ge of gas between the outside of said closure
and the inside of said reservoir.
The gas containing reservoir is designed so as to allow a controlled exchange of
gas from the inside of the reservoir into the inside of said container, i.e., for example into the
empty space in the container between the product and the closure (head space). According to
one embodiment of the disclosure the exchange of gas may take place by means of
permeation. Alternatively, the exchange of gas may also take place by other means, for
example by means of microperforation. According to yet another ary embodiment of
the disclosure the gas containing reservoir may also comprise an oxidant releasing agent as
defined herein.
Suitable gases that may be ned in the reservoir include, but are not limited
to, air, oxygen, ozone, nitrogen, sulfur oxides (in particular: sulfur dioxide), carbon oxides (in
ular: carbon dioxide) and mixtures thereof. According to one aspect of the invention
the reservoir is filled with air.
According to another aspect of the disclosure the gas containing reservoir may
extend into the inside of the container, which may, for example, be a wine . By
extending into the inside of the container, the reservoir reduces the headspace above the
filling level of the container. Thus, in the case of a wine bottle, by extending into the portal
forming neck of the wine bottle the reservoir reduces the headspace above the fluid level of
the wine bottle. According to another aspect of the disclosure, the reservoir is adapted to be
located in the inside of the container y the outer walls of the reservoir are devoid of
contact with an inner wall of the container. Thus, in the case of a wine bottle, the oir
may be adapted to be located within the mouth of the bottle while the outer walls of the
reservoir are devoid of t with an inner surface of the mouth of the bottle. In another
aspect of the disclosure the reservoir may be adapted to be located in the inside of the
container so that it does not effect a seal with an inner surface of the container (e.g., with an
inner surface of the mouth of a bottle). In this aspect of the disclosure effecting a seal may in
W0 2012f120109
particular be avoided during insertion and/or extraction of the reservoir into the container
(e.g., into a mouth of a bottle).
The reservoir may have any d volume and shape. Suitable shapes of the
reservoir may include, but are not limited to, for example, a substantially cylindrical shape, a
substantially conical shape, a substantially half spherical shape, or a ntially dome
shape. ing to one aspect of the disclosure, the reservoir may have a substantially
cylindrical shape. According to another aspect of the disclosure the reservoir may be
substantially in alignment with a portal g neck of the container, i.e., for example, with
the portal forming neck of a wine bottle.
According to another aspect of the disclosure, the reservoir may contain a gas
volume of 0.01 to 30 cc at ambient pressure and t ature, in particular of 0.1 to
cc, or 0.5 to 10 cc at ambient pressure and ambient temperature.
The membrane is constructed so as to allow an at least partial exchange of gas
between the inside of the reservoir and the inside of the container. By way of example, such
exchange of gas may take place by means of permeation through the membrane. The
membrane may be made of any suitable material including, but not limited to, plastic
material. For example, the membrane may be a plastic film, a ted film, a multi-layer
film, a metalized plastic film, an injection molded plastic part, an extruded plastic part, a co-
extruded plastic part, a -formed plastic part, a blow—molded plastic part, a rawn
plastic part or the like. The membrane may form an integral part of the reservoir (e.g., the
bottom flat terminating end of a cylindrically shaped reservoir). Alternatively, the membrane
may form a separate part of the e (e.g., a separate plastic film arranged at or affixed to
the bottom flat terminating end of a cylindrically shaped reservoir).
According to one aspect of the disclosure the membrane may have an oxygen
permeation of about 0.00001 to about 0.1 cc/day per container in 100% air at ambient
pressure and ambient temperature, in particular of about 0.00005 to about 0.05 cc/day per
container, or 0.0001 to about 0.01 cc/day per container, or 0.0005 to about 0.005 cc/day per
container. Air as used herein is defined to contain approximately 20.8 vol.% oxygen.
According to another aspect of the disclosure, the membrane may have an oxygen permeation
at ambient re and ambient temperature that is different from that of the barrier layer.
According to yet another aspect of the sure, the membrane may have an oxygen
permeation at ambient pressure and ambient temperature that is greater than that of the barrier
layer.
The barrier layer is constructed so as to at least partially prevent exchange of
between the outside of the closure and the inside of the reservoir. In particular, the barrier
layer may for e be constructed so as to at least partially prevent exchange of gas
between the outside of the closure and the inside of the reservoir by means of permeation.
The barrier layer may be made of any suitable material including, but not limited to, metal,
plastic material, laminated plastic material and metalized plastic material. For example, the
barrier layer may be a metal film, a plastic film, a laminated film, a multi—layer film, a
metalized plastic film, an injection moulded plastic part, an extruded plastic part, a co—
extruded plastic part, a vacuum—formed plastic part, a blow-molded plastic part, a deep~drawn
c part or the like. The barrier layer may form an integral part of the reservoir (e.g., the
top flat terminating end of a cylindrically shaped reservoir). Alternatively, the barrier layer
may form a separate part of the closure (e.g., a separate film arranged at or affixed to the top
flat terminating end of a cylindrically shaped reservoir).
According to one aspect of the disclosure the barrier layer may have an oxygen
permeation of about 0 to about 0.05 cc/day per ner in 100% air at ambient pressure and
ambient temperature, in particular of about 0 to about 0.01 cc/day per container, or of about 0
to about 0.002 cc/day per container, or of about 0 to about 0.001 cc/day per container in
100% air at t pressure and ambient temperature. According to another aspect of the
disclosure the barrier layer may have an oxygen permeation at ambient
pressure and ambient
ature that is different from that of the membrane. According to yet another aspect of
the disclosure, the barrier layer may have an oxygen permeation at ambient re and
t temperature that is r than that of the membrane. According to yet another
aspect of the sure, the barrier layer and the membrane may have about the same oxygen
permeation at ambient pressure and ambient temperature.
According to another aspect of the disclosure, the closure may further comprise a
body made of metal or polymer al, or a combination thereof. Suitable metals for the
body may include, but are not limited to, for example, aluminum, tin, and/or alloys thereof.
Suitable polymers for the body may e, but are not limited to, for example, PE, PP, PET,
LDPE, styrene block copolymers, EVA, and/or HDPE, and/or es thereof.
ing to yet another aspect, the sure relates to a closure system
comprising a e as described herein and a t retaining container. The product
retaining container may be of any desired shape, size and material. According to one aspect
of the disclosure, the product retaining container may be a wine bottle.
PCTXEP2012/054084
According to yet another , the disclosure relates to a container comprising:
(1) a closure as described herein; and (2) a product. The container may be wholly or lly
filled with any kind of t, in particular with foodstuffs, for example with s (e.g.,
wine or spirits) or solids (e.g., spices). According to one embodiment of the disclosure, the
container is a wine bottle made of glass or plastic that is wholly or partially filled with wine
and sealed with a e as described herein.
ing to yet another aspect, the disclosure relates to a method of adjusting the
oxygen content in a container (e.g., a wine bottle) over a defined period of time comprising:
(1) filling the container with a defined quantity of product (e.g., with wine), and (2) closing
the container with a closure as described herein, so that oxygen is allowed to be released from
the reservoir into the head space of the container or into the t (e.g., into the wine).
In such method, the defined period of time may vary depending on the nature
and/or quantity of product contained in the container. For e, if wine is used as
product, the defined period of time may vary between about 1 day and about 10 years, more
particularly between about 30 days and about 5 years, or n about 60 days and about 3
years, or between about 90 days and about 2.5 years, or n about 180 days and about 2
years.
According to a further ment of the disclosure, at the beginning of the
defined period of time the oxygen permeation rate into the headspace of the container or into
the t may be substantially equal to the permeation rate of oxygen through the
membrane at that time. According to yet another embodiment of the disclosure, at the end of
the defined period of time, the oxygen permeation rate into the headspace of the container or
into the t may be substantially equal to the permeation rate of oxygen through the
barrier layer at that time.
According to an exemplary embodiment, the closure may, for example, be a screw
cap closure. Referring now to Figure 12, a screw cap closure 80 adapted to fit on a wine
bottle 81 is illustrated. In this embodiment, the wine bottle 81 includes threads 82‘ on an

a membrane 191 forming the bottom flat terminating end of the cylindrically shaped reservoir
190. In this embodiment, the outer metal cap 183 forms the top flat terminating end of the
cylindrically shaped reservoir 190 and serves as a barrier layer. The inside 193 of reservoir
190 is filled with a gas such as, for example, air or oxygen. The membrane 191 allows
permeation of gases between the inside 193 of oir 190 and the head space 194 above
the fluid level 195 of{the wine bottle 181 filled with wine 196, thus replenishing oxygen into
the head space 194 of the wine bottle 181 for a defined period of time.

period of time.
Referring now to Figure 15, a further alternate exemplary embodiment is
illustrated. ‘ In this embodiment, a screw cap closure 380 adapted to fit on a wine bottle 381 is
illustrated. The wine bottle 381 includes s 382 on an upper opening as is well
