Description

SCREW CAP FOR CONTAINER AND METHOD OF USE AND MANUFACTURE THEREOF DOMAIN

The technology currently disclosed generally relates to caps or lids for containers. More particularly, in one embodiment, the currently disclosed technology relates to screw caps having a flip-top lid having a first sealing element, a bottom portion having a second sealing element, and an active polymer component.

CONTEXT

Commercial containers for medicines, for example for tablets and capsules, are typically supplied in the form of glass or plastic bottles with removable caps (often having some type of child-resistant configuration). For example, over-the-counter (OTC) pain relief tablets, allergy medications, as well as nutraceuticals and vitamins, are often supplied in such bottles. Generally, the complexity, and therefore cost, of such containers increases as the ability of such containers to resist moisture infiltration increases.

Typically, to ensure that the contents of the bottle have not been tampered with, a flexible seal (usually made of aluminum foil, paper, flexible/thin plastic, cardboard, or a composite of one or of several of the preceding elements) provides a seal to the opening of the container. The first time a user wishes to access the contents of the container, the user can permanently puncture the seal or remove at least part of it. An intact seal protects the container contents from the surrounding environment and provides users with a visual indicator that the container has not been tampered with.

Depending on the nature of the contents of the container, the environment inside the container may need to be controlled. For example, a desiccant or other active material may be needed to control the moisture density inside the container. Typically, a desiccant is supplied in the form of a desiccant-containing sachet or cylindrical container, which sits freely inside the container body, along with the contents of the container. However, having such a sachet or container placed loosely inside the container is cumbersome and impractical because the sachet or container may fall out of the container or, sometimes, block the opening of the container, prompting a maneuver of the user to remove or reposition the sachet or container to extract the contents. As such, the sachet or container may be lost or the user may forget to place the sachet or container back inside the container after use, thereby resulting in the loss of the desiccant and thereby reducing the shelf life of the contents of the container. There is therefore a need to provide a desiccant that is constantly present inside the container without the inconvenience or loss associated with having the sachet or container inside the bottle.

Furthermore, containers as described above are typically filled via automated processing.

Tamper-evident seals, such as foil lids, are often applied to cover container openings after filling. Various methods and means for fixing a joint are known, for example via adhesives or heat. The most common method for applying seal is induction sealing. Induction sealing is a process that relies on electrical currents within a material, such as aluminum foil and/or cardboard, to produce heat. Induction sealing and other means of sealing require special devices and materials in a filling line. These types of seals tend to be necessary to preserve the shelf life of the contents of the containers.

Not all filling lines have induction sealing equipment and an aluminum lid is not always desired.

Additionally, where aluminum lids are desirable, once the seal is broken (during initial use), the moisture seal of the bottle is compromised, even if the cap is replaced. Conventional bottle caps do not provide moisture-proof seals.

SUMMARY

There is a need to create improved container caps, as described above. There is therefore a need for a bottle and cap assembly which offers a desirable shelf life to the contents of the bottle without the need for an aluminum lid. These and other needs are addressed by the currently disclosed technology.

DETAILED DESCRIPTION

Although systems, devices and methods are described herein by way of examples and embodiments, those skilled in the art recognize that the technology currently disclosed is not limited to the embodiments or drawings described. Instead, the currently disclosed technology covers all modifications, equivalents and alternatives within the spirit and scope of the appended claims. Features of any of the embodiments disclosed herein may be omitted or incorporated into another embodiment.

Any headings used herein are for organizational purposes only and are not intended to limit the scope of the description or claims. As used here, the word "may" is used in a permissive sense (i.e., have the potential to) rather than in the obligatory sense (i.e., must) .

As used herein, “and/or” means that one or both of the elements separated by such terminology are involved. For example, the expression “A and/or B” would mean A alone, B alone, or both A and B.

As used herein, the statement that two or more parts or components are "coupled" means that the parts are joined or work together directly or indirectly, that is, through one or more intermediate parts or components, as long as a link occurs.

As used herein, "directly coupled" means that two elements are in direct contact with each other. As used herein, "fixedly coupled" or "fixed" means that two components are coupled to move as one while maintaining a constant orientation relative to each other.

As used here, "around" in an expression such as "arranged around [an element, point or axis]" or "extending around [an element, point or or axis]” or “[X] degrees around [an element, point or axis]”, means to surround, extend around or measured around. When used in reference to measurement or in a similar manner, "about" means "approximately", that is, within an approximate range relevant to the measurement, as would be understood by one skilled in the art.

As used herein, "generally" means "generally" relevant to the term being modified as one skilled in the art would understand it.

As used here, the word "unitary" means that a component is created as a single (possibly monolithic) part or unit. That is, a component that has parts created separately and then coupled together as a unit is not a “unitary” component or body.

As used herein, the statement that two parts or components "engage" together means that the parts exert a force against each other either directly or through a or several intermediate parts or components.

As used herein, the term "number" means one or an integer greater than one (i.e., a plurality).

As used herein, the terms "sealed" or "sealed" mean elements which are in contact with each other in such a manner that a generally moisture-tight seal is formed between them. them.

Directional expressions used herein, such as, for example and without limitation, up, down, left, right, upper, lower, front, back and derivatives thereof, refer to the orientation of the elements shown in the drawings and not limiting any claims unless expressly stated therein.

Generally speaking, as used herein, the term "moisture-proof" is defined as having a moisture penetration (after three days) of less than 1,500 µg water, in another mode of embodiment, less than 500 µg of water, in another embodiment, less than 300 µg of water, in yet another embodiment, less than 150 µg of water, as determined by the method following test: (a) place one gram plus or minus 0.25 gram of molecular sieve into the container and record the weight; (b) completely close the container; (c) place the closed container in an environmental chamber at conditions of 80% relative humidity and 72°F; (d) after one day, weigh the container containing the molecular sieve; (e) after four days, weigh the container containing the molecular sieve; and (f) subtracting the first day sample from the fourth day sample to calculate the moisture penetration of the container in units of micrograms of water. A preferred rate of moisture penetration into a sealed moisture-proof container produced in accordance with one aspect of the disclosed concept is in the range of about 200 to 300 µg/day of water or less. A “moisture-tight” seal is therefore a watertight engagement which alone, or in combination with additional watertight connections, helps to make a container “moisture-tight” as defined above.

As used herein, the term "resealable" means that the container lid can be opened or reopened and closed or resealed multiple times (e.g., more than 10 times) while retaining its airtight sealing properties. humidity.

Referring now in detail to the various figures, in which like reference numerals refer to like parts throughout, Figures 1 to 3B show a stopper and container, generally designated 1. The assembly 1 may include a bottle 10 and a cap 100 removably attachable and securely attachable thereto. While bottle 10 illustrated on the is a contemplated or exemplary type of container that may be used in conjunction with the currently disclosed technology, other types of containers are also contemplated. When the term "vial" is used to describe an exemplary embodiment, the broader and more generic term "container" may also be used in its place. The bottle is possibly made of plastic, glass or even a metallic material. While the cap 100 is shown in Figures 1 to 3B and often referred to herein as a screw cap, that is, simply a contemplated or exemplary type of cap that may be used in conjunction with currently disclosed technology, as other types of caps (e.g., snap-on or fully separable) are also considered.

The bottle 10 may include a body 12 having a base 14 and one or more side walls 16 extending upwardly therefrom leading to a rim (e.g. and without limitation, a bottle rim 18 of Figures 3C , 4 and 5C) surrounding an upper opening (for example and without limitation, the opening 20 as shown in Figures 3B and 5B) of the bottle 10. The embodiment shown is cylindrical and therefore has a side wall unitary round 16. However, the containers according to the disclosed concept can have other shapes, for example, a rectangular cuboid, and thus have more than a single continuous side wall (for example, round).

The bottle 10 may include a neck (for example and without limitation, a bottle neck 22 of Figures 3B, 4 and 5B) comprising one or more threads (for example and without limitation, the threads 26 in Figures 3B to C, 4 , 5B to C) to provide threaded engagement with corresponding or complementary threads (for example and without limitation, threads 146, 246, 346 in Figures 3B to C, 4, 5B to C) of the plug 100 when the cap 100 is attached to bottle 10.

The body 12 of the bottle 10 can define an interior space (not shown) configured to store a content (not shown), such as a plurality of medicinal or nutraceutical tablets, capsules or powder, or solid or liquid products in the food industry. , pharmaceutical or chemical. The interior space of the bottle 10 may be accessible through the top opening 20 or the lid opening (for example and without limitation, a lid opening 138 of Figure 3A).

In an optional embodiment, the screw cap 100 may include a flip cover 110, which can move between a first position or open position (see Figures 2, 3A and 3B) and a second position or closed position (see Figures 2, 3A and 3B). Figures 1 and 3C). In particular, the cap 100 may include a lower or base portion 130 to which the cover 110 is pivotally attached via a hinge 119. A neck or lip 150 may extend upwardly from a lower base 134 and may be spaced radially inwardly from an outer periphery 132 of the base portion 130. An inner periphery of the neck 150 may form an opening 138 leading to an interior of the cap 100. Since the neck 150 is raised from and/or above an upper surface of the lower base 134, at least one upper portion of the hinge 119 is also raised from and/or above the upper surface of the lower base 134 via at minus one or more spaced risers 115 and/or other features, such that the flip cover 110 is raised to properly or conveniently mate with the raised neck 150 and extend perpendicular to the neck 150 in a closed position.

In an optional embodiment, the riser(s) 115 is/are fixedly attached to the upper surface portion of the lower base 134. The lower portion 130 and the flip cover 110 are discussed in more detail later. In an optional embodiment, hinge 119 may be a living hinge. In another optional embodiment, the hinge 119 may include a pin or axle by which other parts of the hinge 119 rotate. An axis of the hinge 119 may extend perpendicular to an axis of the bottle 10 when the cap 100 is attached to the bottle 10. Optionally, a neck 150 may extend upwards from the lower part 130. In one mode embodiment, the neck 150 is cylindrical or circular in top view, and is surrounded by and/or engaged with a part of the cover 110 when the cover 110 is in the closed position.

The embodiment shown includes the bottle 10 and the lower portion 130 of the cap 100 as removably attachable to each other via, for example and without limitation, threaded engagement. However, the containers according to the disclosed concept may comprise a unitary unit integrating the bottle 10 and the cap 100 during manufacture, and the assembly 1 can be opened or closed by operating a hinged lid 110 to access the contents of the container.

In one embodiment, the cap 100 is optionally manufactured primarily or partially from one or more injection moldable thermoplastic materials, including, for example, a polyolefin such as polypropylene or polyethylene.

For some uses, a child-resistant cap may be desired, but may not be necessary for all applications. Thus, child-resistant and non-child-resistant caps are being considered. If a child-resistant feature is provided, the child-resistant feature may require that force in more than one direction be applied to the cap to remove the cap from the container. For example, the cap may require a user to press down (first direction) before rotating the cap (second direction) to remove the cap from the container. Alternative child-resistant features, if desired, are also being considered.

While the screw cap 100 illustrated in Figures 2 to 3C may be removably attached to the bottle 10, for ease and completeness of description, Figures 2 to 3C also include the components (e.g., without s limit thereto, a bottle rim 18, an opening 20 leading to an interior of the body of the bottle 10, a bottle neck 22) of the bottle 10 which would be represented if the screw cap 100 is fixed to the neck of the bottle 10 via, for example, without limitation, thread engagement as discussed in relation to .

In an optional embodiment, the flip cover 110 is pivotally attached to the bottom 130 via the hinge 119. The cover 110 has a cover base 114 and an annular cover skirt 124 extending downwardly at of an outer periphery of the lid base 114. Optionally, the hinge 119 is raised from an upper surface of the lower base 134 via one or more risers 115 fixedly attached thereto, such that the cover 110 is raised to mate with a neck rim 158 and extend perpendicular to the neck 150 in a closed position.

Optionally, the hinge 119 comprises at least one flap 116 extending from the riser(s) 115 over a distance which is substantially equal to a lateral distance between the outer periphery 132 and an inner periphery 131 of the lower base 134, so that the lid base 114 completely covers the opening 138 when the lid 110 is in the closed position. Optionally, the hinge 119 and/or the riser(s) 115 comprise one or more rear walls 117 having at least the same height as the neck 150. Optionally, the one or more rear walls 117 can be fixed to part of the periphery outer 132 of the lower base 134. Optionally, one or a pair of side walls 118 extend inwardly towards the neck 150 from side edges of the one or more rear walls 117 for a distance which is substantially equal or less at a distance between the outer periphery 132 and the inner periphery 131 of the lower base 134 such that the cover skirt 124 is configured to fit between the one or more pairs of walls 118 and a neck skirt 164 of the neck 150 when the cover 110 is in the closed position. Optionally, the riser(s) 115 and one or more other parts of the hinge 119 comprise or are formed of a thermoset. Optionally, the riser(s) 115 and one or more other parts of the hinge 119 comprise or are formed of a thermoplastic or a thermoplastic elastomer. Optionally, the lid skirt 124 has a radially inwardly extending flange 126 and is configured to contact and/or mate with the neck rim 158 when the lid 110 is in the closed position.

Optionally, the cover 110 may include a first sealing element 120. Optionally, the cover base 114 may be flat or planar, and the cover skirt 124 may be cylindrical or circular. The annular cover skirt 124 may include an annular rim 126 extending radially inward. The flip cover 110 may further include a fixed projection (also called a pull tab) 112 at a distal end opposite the hinge 119. The projection 112 may extend radially outward from the cover base 114 and/or lid skirt 124. Pull tab 112 may be configured to be actuated and/or engaged to place lid 110 in the open or closed position. Optionally, the first sealing element 120 is disposed on an interior surface of the cover base 114. The first sealing element 120 may include or be a thermoplastic elastomer sealing element disposed around the entire periphery of the surface interior of the cover base 114. Optionally, the thermoplastic elastomer sealing element 120 has an annular portion configured to sealingly engage with the neck rim 158.

In an optional embodiment, the lower base 134 may have a lower skirt 144 extending downwardly at the outer periphery 132 (see Figure 3A) thereof and the neck 150 may project upwardly. from the internal periphery 131 of the lower base 134 and/or the lower part 130. The internal periphery 131 can form the opening 138 leading to an interior of the cap 100. Optionally, the neck 150 can also include the rim of neck 158 extending radially outwardly from an upper end of the neck 150. Optionally, the neck 150 includes the annular neck skirt 164 which extends upwardly from the inner periphery 131 of the base lower 134 and the collar rim 158 can extend radially outwards from an upper end of the collar skirt 164. Optionally, the lower base 134 can be flat or planar. The opening 138 may have a size substantially equal to or smaller than the size of the lid base 114. In embodiments in which the cap 100 is fixedly attached to the bottle 10, the opening 138 leads to an interior ( not shown) of the bottle 10 via an upper opening 20 (see Figure 3B) of the bottle 10.

The lower skirt 144 may optionally include one or more threads extending radially inward from an interior surface thereof. The one or more threads may be configured to sealingly engage one or more bottle threads disposed on an upper portion of a side wall 12 of the bottle 10. Optionally, the neck skirt 164 may include a neck skirt lower 165 (see Figure 3C) which extends downwards under the lower base 134 and inside the cap 100.

Optionally, the cap 100 may not include any sealing element, only the first sealing element 120, or two or more sealing elements. For example, the cap 100 may include the first sealing element 120 disposed on an interior surface of the lid base 114. In the closed position, the hinged lid 110 pivots about the hinge 119 so that the lid 110 covers the opening 138, while the first sealing element 120 comes into sealing engagement with at least part of the neck rim 158. Optionally, the flange 126 can come into engagement or come into contact with an exterior surface of the skirt of neck 164, and can secure the cover 110 to the neck 150 via, for example, without limitation, a friction fit, and causes the first sealing member 120 to compress against an upper engagement surface of the neck rim 158 This can create a moisture-proof seal between the cover 110 and the neck 150 of the cap 100, and therefore, between the cap 100 and the bottle 10, when the cover is in the closed position.

Optionally, as shown in Figures 3C and 3B, the lower base 134 of the lower part 130 may also include a second sealing element 140 disposed on a first part of an interior surface (lower face) of the lower base 134. Optionally, the second sealing element 140 may be in the form of an annular ring or an O-ring, and have a generally square or rectangular cross-sectional shape. In the closed position, the engagement between the threads 146 of the lower skirt 144 and the corresponding threads 26 on the neck 22 of the bottle 10 firmly fixes the cap 100 to the bottle 10 and causes the second sealing element 140 to compress to the less lightly when it presses firmly against an upper engaging surface 19 of the rim 18 of the neck 22. This creates an additional moisture-tight seal between the cap 100 and the bottle 10, further improving the watertight seal. humidity of the environment inside the set 1.

Optionally, the lower base 134 may also include an active component 142, such as but not limited to an active polymer component, on a second part 135 of the lower face of the lower base 134, which is surrounded by and, possibly in contact with an internal annular edge of the second sealing element 140 or is spaced at least slightly radially inwardly of the second sealing element 140. Optionally, the active component 142 may surround the lower neck skirt 165. Optionally, the lower base 134 may include a rib 148 extending downwardly from a third portion of the interior surface of the lower base 134 and disposed between the second sealing element 140 and the active component 142. The active component 142 and the first and second sealing elements 120, 140 are discussed in more detail below.

The active component 142 may be fixed or molded into the second portion 135 of the underside of the lower base 134. The active component 142 allows the container assembly 1 to provide improved capabilities in terms of protection against moisture penetration , for example and without limitation, of medicines contained inside the bottle 10.

The active component 142 may comprise a base polymer entrained with one or more active agents, and may therefore be called here polymer entrained with an active agent or entrained polymer. The active agent in active component 142 may include an absorbent material, a release material and/or an activation material. Optionally, active component 142 is a desiccant-entrained three-phase polymer.

The active component 142 can be in different shapes, volumes and/or configurations. In the exemplary embodiment shown, the active component 142 may be in the form of a ring concentric with the lower annular skirt 144. The active component 142 may surround, and possibly come into contact with, an outer annular edge of the lower neck skirt 165 of the neck 150. In one embodiment, the active component 142 may extend into and/or be exposed to an interior space of the bottle 10 to dehydrate the environment inside the bottle 10. Optionally, the active component 142 surrounds, and possibly comes into contact with, an internal annular edge of the rib 148. Thus, the lower neck skirt 165, a part of the lower face of the lower base 134, and the rib 148 form possibly a cavity allowing the active component 142 to be molded on the cavity.

In one embodiment, active component 142 is a desiccant-entrained polymer that is a unitary component consisting of a single piece of material. An entrained polymer, whether entrained with a desiccant or other active agent, may include a base polymer (for structure), a desiccant (or other active agent), and optionally a channel-forming agent. These types of active polymer components and the methods of making and using them are disclosed, for example, in Applicant's U.S. Patent Nos. 5,911,937, 6,214,255, 6,130,263, 6,080,350, 6,174,952, 6,124,006 and 6,221,446, and Publication US Patent No. 2016/0039955. Optionally, the entrained polymer may be in the form of a film that is loose or possibly heat-bonded to a surface.

Alternatively, the desiccant may include bulk desiccant beads or a sachet containing them. Although the exemplary embodiments here reflect that the active component 142 is located on the second portion 135 of the lower base 134 and around the lower collar skirt 165 of the collar 150, it is contemplated that one or more active agents can be located at other locations and/or positions, such as on a side wall 16 of the body 12 or the neck 22 of the bottle 10.

In the embodiment where each active component 142 contains a desiccant, moisture absorption is desired. However, when moisture absorption is not desired, active component 142 may include alternative active agents. For example, in another embodiment, active component 142 contains a material selected from the group consisting of activated carbon, carbon black, Ketjen black and diamond powder. In another embodiment, an active agent comprising one or more layers of the active element contains a material such as absorption microspheres, BaTiO3, SrTiO3, SiO2, Al2O3, ZnO, TiO2, MnO, CuO, Sb2O3, silica, calcium oxide and ion exchange resins. In yet another embodiment, the absorbent-containing layer of the active component 142 contains two or more types of absorbents. The appropriate absorbent agent is chosen to achieve the desired vapor or gas absorption for the desired end use (e.g. absorption of moisture, oxygen, carbon dioxide, nitrogen or other unwanted gases or vapors).

The active element (whether a desiccant, oxygen scavenger, release material or ingredient, etc., or a combination thereof) is capable of acting on, interacting with, or reacting with a selected material ( for example, humidity or oxygen). Examples of such actions or interactions may include absorption, adsorption (usually sorption) or release of the selected material. Each active element can be extruded or molded, for example. Optionally, the active element can be formed into a desired shape or pattern (e.g., on a support) via an in-line melt adhesion thermal bonding process.

Active component 142 may include an “active ingredient” in a base material. The active ingredient(s) (i) may be immiscible with the base material (e.g. polymer) and when mixed or heated with the base polymer and a channel forming agent will not be mixed, that is, they have a melting point that is higher than the melting point for either the base polymer or the channel-forming agent, and/or (ii) act on, interact with or react with a selected material. The term “active ingredient” may include, but is not limited to, materials that absorb, adsorb, or release the selected material(s). The active ingredients, depending on the currently disclosed technology, may be in the form of particles such as minerals (e.g., molecular sieve or silica gel, in the case of desiccants), but the currently disclosed technology need not be considered to be limited only to particulate active agents. For example, in some embodiments, an oxygen scavenger formulation may be made from a resin that acts as, or as a component of, the active agent.

As used herein, the term "base material" is a component (preferably a polymer) of an entrained active material, other than the active agent, which provides structure to the entrained material.

As used herein, the term "base polymer" is a polymer optionally having a gas transmission rate of a selected material that is substantially less, less than, or substantially equivalent to that of the channel forming agent. As an example, such a transmission rate would be a water vapor transmission rate in embodiments where the selected material is moisture and the active ingredient is a water-absorbing desiccant. The primary function of the base polymer is to provide structure to the entrained polymer. Suitable base polymers may include thermoplastic polymers, for example polyolefins such as polypropylene and polyethylene, polyisoprene, polybutadiene, polybutene, polysiloxane, polycarbonates, polyamides, ethylene-vinyl acetate copolymers, ethylene-methacrylate copolymer, poly(vinyl chloride), polystyrene, polyesters, polyanhydrides, polyacrylonitrile, polysulfones, polyacrylic ester, acrylic, polyurethane and polyacetal, or their copolymers or mixtures thereof.

Referring to such a comparison of the water vapor transmission rate of base polymer and channel former, in one embodiment the channel former has a vapor transmission rate d water of at least twice that of the base polymer. In another embodiment, the channel forming agent has a water vapor transmission rate of at least five times that of the base polymer. In another embodiment, the channel forming agent has a water vapor transmission rate of at least ten times that of the base polymer. In yet another embodiment, the channel forming agent has a water vapor transmission rate of at least twenty times that of the base polymer. In yet another embodiment, the channel forming agent has a water vapor transmission rate of at least fifty times that of the base polymer. In yet another embodiment, the channel forming agent has a water vapor transmission rate of at least one hundred times that of the base polymer.

As used herein, the term "channel forming agent" or "channel forming agents" is defined as a material that is immiscible with the base polymer and has an affinity for transporting a substance into the gas phase. at a faster speed than the base polymer. Optionally, a channel forming agent is capable of forming channels through the entrained polymer when formed by mixing the channel forming agent with the base polymer. Eventually, such channels are capable of transmitting a selected material through the entrained polymer at a faster rate than in the base polymer alone.

As used herein, the term "channels" or "interconnecting channels" is defined as passages formed of the channel-forming agent which penetrate through the base polymer and can be interconnected with one another.

As used herein, the term "entrained polymer" is defined as a monolithic material formed of at least a base polymer with an active agent and optionally also a channel-forming agent entrained or distributed throughout. An entrained polymer thus comprises two-phase polymers and three-phase polymers. A “mineral-filled polymer” is a type of entrained polymer, where the active agent is in the form of minerals, for example mineral particles such as molecular sieve or silica gel. The term "entrained material" is used herein to denote a monolithic material comprising an active agent entrained in a base material, the base material which may or may not be polymeric.

As used herein, the term "monolithic", "monolithic structure" or "monolithic composition" is defined as a composition or material that does not consist of two or more discrete macroscopic layers or parts. Thus, a “monolithic composition” does not include a multilayer composite.

As used herein, the term "phase" is defined as a part or component of a monolithic structure or composition that is uniformly distributed throughout, to give the structure or composition its monolithic characteristics.

As used herein, the term "selected material" is defined as a material that acts on, through, or interacts with or reacts with an active agent and is capable of being transmitted through the channels of an entrained polymer. For example, in embodiments in which a desiccant is used as the active agent, the selected material may be moisture or a gas that can be absorbed by the desiccant. In embodiments in which a release material is used as the active agent, the selected material may be an agent released by the release material, such as moisture, fragrance, or an antimicrobial agent (e.g., chlorine dioxide). In embodiments in which an adsorbent material is used as the active ingredient, the selected material may be certain volatile organic compounds and the adsorbent material may be activated carbon.

As used herein, the term "three-phase" is defined as a monolithic composition or structure having three or more phases. An example of a three-phase composition according to the currently disclosed technology would be an entrained polymer formed from a base polymer, an active agent and a channel forming agent. Optionally, a three-phase composition or structure may include an additional phase, for example a dye.

The entrained polymers may be two-phase formulations (i.e. comprising a base polymer and an active ingredient, without a channel-forming agent) or three-phase formulations (i.e. comprising a base polymer, an active agent and a channel forming agent). Entrained polymers are described, for example, in U.S. Patent Nos. 5,911,937, 6,080,350, 6,124,006, 6,130,263, 6,194,079, 6,214,255, 6,486,231, 7,005,459, and U.S. Patent Publication No. 2016/003 9955.

An entrained material or polymer includes a base material (e.g. a polymer) to provide structure, optionally a channel forming agent and an active agent. The channel forming agent forms microscopic interconnecting channels through the entrained polymer. At least a portion of the active ingredient is contained in these channels, such that the channels communicate between the active ingredient and the exterior of the entrained polymer via microscopic channel openings formed at external surfaces of the entrained polymer. The active ingredient may be, for example, any of a variety of absorbent, adsorbent or release materials, as described in more detail below. Although a channel-forming ingredient is preferred, currently disclosed technology largely involves entrained materials which optionally do not include channel-forming agents, e.g., two-phase polymers.

In any embodiment, suitable channel forming agents may include a polyglycol such as polyethylene glycol (PEG), ethylene vinyl alcohol (EVOH), polyvinyl alcohol (PVOH), polyamine glycerin , polyurethane and polycarboxylic acid, including polyacrylic acid or polymethacrylic acid. Alternatively, the channel forming agent may be, for example, a water-insoluble polymer, such as a propylene oxide polymer monobutyl ether, such as Polyglykol B01/240, produced by CLARIANT. In other embodiments, the channel forming agent could be a monobutyl ether of propylene oxide polymer, such as Polyglykol B01/20, produced by CLARIANT, a propylene oxide polymer, such as Polyglykol D01/240, produced by CLARIANT, ethylene vinyl acetate, nylon 6, nylon 66, or any combination thereof.

Suitable active ingredients according to currently disclosed technology include absorbent materials, such as desiccant compounds. If the active agent is a desiccant, any desiccant appropriate for a given application may be used. Typically, physically absorbed desiccants are preferred for many applications. These can include molecular sieves, silica gels, clays and starches. Alternatively, the desiccant may be a chemical compound that forms water-containing crystals or compounds that react with water to form new compounds.

Optionally, in any embodiment, the active agent may be an oxygen scavenger, for example an oxygen scavenging resin formulation.

Referring again to Figures 2 and 3A to C, to provide a moisture-tight seal between the cap 100 and the bottle 10, the cap 100 may include the first sealing element 120 and/or the second element d seal 140 to provide a moisture-proof environment within the container 1. The first and second sealing members 120, 140 may be made from an elastomer, such as thermoplastic elastomer (TPE). , or any other material capable of providing the desired functionality, such as any material that can be compressed repeatedly without sacrificing its integrity.

As used herein, the TPE may optionally have a Shore A hardness of 20 to 50, preferably 20 to 40, more preferably 20 to 35. The TPE may preferably be injection moldable soft and elastic materials suitable for create a compression seal against a harder surface (for example and without limitation, thermoplastic) of the cap 100 and/or the bottle 10. In any embodiment, the TPE must be configured for repeated use, i.e. -say that it must not degrade over several cycles (for example, at least 10, preferably at least 25, more preferably at least 50 cycles) of opening and closing. By incorporating TPE to create elastomer-thermoplastic seals (e.g., but not limited to, a seal between the first sealing member 120 and the upper engagement surface of the neck rim 158 or a seal between the second sealing element 140 and the upper engagement surface 19 of the bottle rim 18), the assembly 1 allows the TPE seal 120, 140 to further reduce the water vapor transmission rate (MVTR), and therefore requires less, if any, protection from moisture via any dehydration process to achieve a targeted shelf life. In addition, assembly 1 comprising both the first and second sealing elements 120, 140 provides an even lower MVTR than a container comprising only one of these TPE seals 120, 140.

Referring to Figures 2 to 3C, the first sealing element 120 is optionally a compressible seal attached to or integral with at least a portion of the underside of the cover base 114. The first sealing element 120 can comprise an annular portion 121 and a linear portion 122 extending through the annular portion 121. The annular portion 121 may be located on an interior surface or an underside of the lid base 114 of the flip lid 110. The annular portion 121 engages and forms a seal, such as a moisture seal, with the rim 158 of the neck 150 of the cap 100. The linear portion 22 may extend through the cover 110 and below a geometric center of the cap 100. lid 110. When the lid 110 is attached to the neck 150 of the cap 100 to close the opening 138, the first sealing element 120 engages with the neck rim 158. Optionally, the rim 126 of the lid skirt 124 engages an exterior surface of the neck skirt 164, secures the cover 110 to the neck 150, and/or causes the first sealing member 120 to compress against an upper engagement surface of the neck rim 158. This causes a moisture seal between the cover 110 and the neck 150, and therefore, between the cap 100 and the bottle 10 in the closed position.

In an optional embodiment, the second sealing element 140 is a compressible seal fixed or integral with at least part of the lower face of the lower base 134. Optionally, the second sealing element 140 may have the shape of a ring, which surrounds and possibly comes into contact with an outer annular edge of the active polymer component 142. When the cap 100 is attached to the bottle 10 to cover the opening 20 of the bottle 10, the second sealing element 140 enters in contact with the upper engagement surface 19 of the rim 18 of the bottle 10. That is to say, the engagement between the threads 146 of the cap 100 and the threads 26 on the neck 22 of the bottle 10 firmly fixes the cap 100 to the bottle 10 and/or causes the compression of the second sealing element 140 when it presses firmly against the upper engagement surface 19 of the bottle rim 18.

As such, the first sealing element 120 or the second sealing element 140 can alone provide a moisture-tight seal between the cap 100 and the bottle 10, providing a lower MVTR than that of a container without these TPE seals 120, 140. When the first and second sealing elements 120, 140 are present in the cap 100, these seals ensure moisture tightness and thus further reduce the MVTR, thus extending and achieving the optimal target shelf life of the bottle contents.

The currently disclosed technology has simplified the manufacturing process compared to the prior art. Depending on the technology currently disclosed, the cap 100 can be manufactured in various ways. An optional method of forming or manufacturing the cap 100 involves injection molding. More particularly, a method of forming or manufacturing the cap 100 comprises multi-shot injection molding. For example, the cap 100 may be manufactured in a two-shot injection molding process if the active component is not included, or a three-shot injection molding process if the active component is included.

Optionally, in a three-shot manufacturing process, the first shot in the mold would be active component 142 (e.g., a desiccant-entrained polymer with a channel-forming agent). The second shot in the mold would be one or both compressible seals 120, 140 (e.g., TPE). The third shot would be the rest of the cap (for example, using a polyolefin material). The three-shot injection molding process is described, for example, in International Publication No. WO 2021/076874 and other relevant techniques are described in American Publication No. 2021/0008771.

In at least one embodiment, the disclosed concept creates an improved seal over prior art containers, and avoids the need for an aluminum lid or other type of heat-sealed material over the opening for the storage. The first and second sealing elements 120, 140 are configured to provide sufficient and/or improved closure integrity over the shelf life of the contents of the bottle 10 so as not to require an aluminum lid or the like.

Optionally, a tamper-evident mechanism may be provided on the cap 100. For example, an integrated polymer tamper-evident ring, such as that typically found on a water bottle, may be provided. During production, possibly after the above-mentioned process has been executed and the cap 100 has been ejected from the mold, a molded tamper evident ring may be placed directly onto the cap by an automated process (e.g., without s limited to a robot). Alternatively, a retractable seal may be provided on/around the cap 100. In embodiments comprising a removable screw cap 100, the tamper evident element may be integrated at a lower end of the lower skirt 144 , the lower end being opposite the outer periphery 132 of the lower base 134. In embodiments having the screw cap 100 fixedly attached to the bottle 10, the shrink seal may be used.

There shows another embodiment of a screw cap 200 of currently disclosed technology. The screw cap 200 is substantially similar to the screw cap 100 of Figures 2 to 3C, discussed above. Thus, similar or identical characteristics between the two embodiments are distinguished on the by a reference number one hundred (100) greater than that of Figures 2 to 3C. Only certain distinctions between the two embodiments will be discussed here for brevity and convenience only, which is not limiting or implying that a certain feature or component is not present in this embodiment.

The screw cap 200 of the differs from the screw cap 100 of Figures 2 to 3C in that the screw cap 200 does not include the active component 142 of the screw cap 100. However, the effect of the absence of the active component 142 on the contents of the container is minimized in that having one or both of the first and second sealing elements 120, 140 reduces the MVTR compared to a container without such a TPE seal. As such, even without the active component 142, the container 1 can provide the targeted shelf life with only one or both first and second sealing elements 120, 140.

Figures 5A to C show another embodiment of a screw cap 300 of the currently disclosed technology. The screw cap 300 is substantially similar to the screw cap 100 of Figures 2 to 3C, discussed above. Thus, similar or identical characteristics between the two embodiments are distinguished in Figures 5A to C by a reference number two hundred (200) greater than that of Figures 2 to 3C. Only certain distinctions between the two embodiments will be discussed here for brevity and convenience only, which is not limiting or implying that a certain feature or component is not present in this embodiment.

The screw cap 300 of Figures 5A to C differs from the screw cap 100 of Figures 2 to 3C in that, although the cap 300 includes the active component 342, the screw cap 300 does not include one or both of the first and second sealing elements 120, 140. As such, the screw cap 300 provides a seal created by the threaded engagements between the one or more threads 346 on the internal surface of the lower skirt 344 and the one or more threads 26 on the neck 22 of the bottle 10 as well as the engagement between the flange 326 of the lid skirt 324 and the outer surface of the neck skirt 364. However, with the active component 342 embedded in the Inside the cap 300 (in particular, the lower base 334 of the cap 300), the assembly 300 is capable of providing constant dehydration, for example, to the environment of the assembly 300 in the closed position, thereby extending the duration conservation of the contents of the bottle 10.
