Certain features or components of the illustrative containers and devices shown in the figures may have been enlarged, distorted or otherwise shown in a non-conventional manner relative to other features or components to facilitate a better understanding of the novel containers and devices disclosed herein. It will be recognized by the person of ordinary skill in the art, given the benefit of this disclosure, that the containers and devices disclosed herein can be used in any orientation relative to gravity and suitable orientations will be readily selected by the person of ordinary skill in the art, given the benefit of this disclosure. References made to beverage containers herein is not intended to limit the disclosure to beverage containers, but instead refers to containers that may be used to hold various contents, including consumable and non-consumable goods.
DETAILED DESCRIPTION OF THE INVENTION
Certain examples of the devices and methods disclosed herein will be recognized by the person of ordinary skill in the art, given the benefit of this disclosure to provide sanitary, cost-effective containers. In particular, beverage containers are provided that have a sanitary cover, are easier to open than conventional cans, and can be repeatedly and securely resealed. The beverage container of certain examples disclosed herein will prevent the dispensing portion of the beverage container from exposure to the environment and ensure a safe and contaminant-free product. The current manufacturing process for beverage cans may be adapted to include the present invention, with reduced, minimal or no additional cost.
Conventional beverage containers, such as aluminum cans, are manufactured by well-known processes. In one process, aluminum cans are made from an aluminum coiled sheet which is fed through a cupping press that cuts discs and forms them into cup-like containers. These cups drop from the press onto a conveyor, and are fed into an ironing press where successive rings redraw and iron the cup, reducing the sidewall thickness, and achieving a full length can. The tops of the can bodies are then trimmed to eliminate rough edges and ensure height uniformity. The can bodies are then cleaned and dried. Subsequently, the can bodies are labeled and coated with a clear protective layer of varnish. The cans are then baked, treated with a coating, and re-baked. The top portion of each can body is narrowed to form a neck with an outward flange at the top edge. The bottom portions are domed to obtain the strength required to withstand internal pressure if a carbonated liquid will be added to the can. After testing for pin-holes and defects, the can bodies are placed on pallets and shipped to a beverage supplier.
The lids of conventional aluminum cans, typically referred to as “can ends,” are made by stamping shells from an aluminum coiled sheet. The shells are coated with a sealant, and subsequently a rivet is placed in each can end. On those cans using a stay-on-tab type closure, the process further includes inserting a separate piece of metal as the tab under the rivet to secure it in place. The edges of the can ends generally have a curved flange. The can ends are also scored to define the opening of the can end in the finished product. The can ends are then shipped to the beverage supplier, along with the can bodies.
At the beverage supplier, a filling machine is used to pour the beverage into the can body. The process is completed after filling when the can end is added, and secured to the can body by forming a double seam with the can body. A double seam is formed by interlocking edges of the two components, the outward top edge of the can body and the curved flange at the edge of the can end, curling the can end flange around the can body edge so that the can end flange is partially rolled up and under the can body edge to form a partial seam, and crimping and flattening the partial seam against the can body to form a hermetic seal.
Most beverage cans have a stay-on-tab type closure such as those disclosed in U.S. Pat. Nos. 3,967,752 and 3,967,753 to Cudzik, and described above. However, there are many aspects of the conventional stay-on-tab closure that make it undesirable. The stay-on-tab closure does not provide for a sanitary drinking environment because the outer surface of the can and the top of the can, which comprises the stay-on-tab closure, comes into contact with the environment during storage, shipping, distribution, display, handling, and ultimately, use by the consumer. When the beverage is poured directly from the can through the opening formed from the stay-on-tab closure, the beverage comes in contact with the top and surface of the can, making for a potentially unsanitary drinking environment. Additionally, if a consumer drinks the beverage from the can directly, both the beverage and the mouth of the consumer come into contact with the surface and top of the can, also making for an unsanitary drinking environment. Additionally, the stay-on-tab type closure does not allow for reclosing the beverage container.
The present invention provides a beverage container that may be manufactured by commercially available processes and machinery with minimal retrofitting, low material and manufacturing costs, ease of stacking during shipping and storage, increased sanitary conditions of the dispensing portion, reliability and ease of opening, closing, and resealing by consumers, pourability, drinkability, recyclability, and decreased likelihood of spilling the contents of the container. These advantages of the present invention overcome the noted deficiencies of the conventional stay-on-tab type closure beverage containers.
The present invention also provides a resealable closure system to use with a beverage container that allows for locking of the system in a secure, closed, sealed position, as well as locking the device in various secure open positions. Additionally, after the beverage container is initially opened, the user may recover and protect the dispensing portion of the container to prevent contaminants from residing in the dispensing portion area.
As used herein, the term “mate” or “mating” may describe any manner of connecting or joining two or more components together. The term “mate” or “mating” may describe any mechanical, thermal, or chemical process that connect or join two or more components together. In the examples disclosed herein, the term “mate” or “mating” may mean welding, soldering, molding, adhering, crimping, folding, double seaming, clamping, snapping, interlocking, fastening or otherwise connecting two components. For example, two or more components of the container may be welded, soldered, molded, adhered, crimped, folded, double seamed, clamped, snapped, or interlocked together. In certain examples, two or more components may be mated by being fastened together with the assistance of another component, thereby forming a rigid or flexible, hinge connection. “Mating” may also mean connecting or joining at least two components having compatible threaded surfaces. The mating may be permanent or temporary.
In accordance with certain examples, a container is disclosed. The container may be used to hold various contents including, but not limited to consumable goods, and may have the ability to reliably seal and reseal the goods within the container. The goods may be in the form of at least one of a solid, liquid or gas. In certain examples, the contents may be a food, beverage, for example, a carbonated beverage, or other consumable. In other examples, the contents may be other than a food or beverage, but may still require sanitary conditions and protection from contamination while dispensing and/or storing.
In accordance with certain examples, a closure system comprising a fixed element and a movable closure system is disclosed. The movable closure element may comprise a top cover and a sealing portion.

It will be within the ability of the person of ordinary skill in the art, given the benefit of the disclosure, to select or to design suitable shapes, sizes and materials for construction of the dispensing portion disclosed herein.
The can end may be constructed and arranged to cooperate with other components of the closure system. The can end may provide a sub-component that allows cooperation with other components of the closure system. The sub-component may allow other components of the closure system to interact with it to accomplish adequate sealing of the container. The sub-component may be constructed and arranged to mate with other components of the closure system to ensure that each component does or does not move relative to a third component. In one embodiment, the sub-component may be an aligner, guide, or connector to control the rate of adjustment of this sub-component to another component. The sub-component may also allow other components of the closure system to fit through this sub-component, allowing various components of the closure system to mate, for example, during assembly of the closure system. The sub-component may be a channel guide. The channel guide may be constructed and arranged to mate with other portions of the closure system, such as portions of the movable closure element. The channel guide may have a first end that participates in a sealing or opening process of the container, and a second end that participates in another sealing or opening process of the container. In some examples, the channel guide may comprise an edge or lip that mates or cooperates with one or more other components of the system. In other examples, the channel guide may be constructed to allow communication between the inside and the outside of the container. The channel guide and dispensing portion may be constructed and arranged such that each opening provides structural integrity to the can end and the beverage container. In certain examples, this may be accomplished by having the channel guide and dispensing portion be combined into one opening. In certain examples, the channel guide and dispensing portion are constructed as at least two openings. This may allow less metal to be removed from the can end, and strengthen it, as compared to another construction that may include one opening comprising the channel guide and dispensing portion.
The can end comprising more than one sub-component may be preassembled and attached to the container body as a collective can end. Alternatively, it may be attached to the container body in consecutive order, along with other components of the closure system. The sub-components of the can end may be both secured to the container body, or one sub-component of the can end may be attached to another sub-component of the can end, which then may be secured to the container body. The securing may be accomplished by mating. Each component of the can may be made of the same or different material from each other and from the other components of the closure system, and the container body.

The dispensing portion of the first component may be aligned with the dispensing portion of the second component. The first component and the second component may be made of the same or different, compatible materials. For example, the first and second component may be made entirely of aluminum or a polymeric material. In the alternative, the first component may be made of aluminum, while the second component may be made of a polymeric material. The dispensing portions of the first and second component may be the same or different size and shape, so long as they provide a clear path to the contents of the container.
The first component of the can end may comprise the channel guide. The channel guide may be positioned in the first component so that it resides in a portion of the dispensing portion of the second component of the can end. The first and second component may both comprise a portion of the channel guide, so that mating of the first and second components of the can end create the channel guide. In certain examples the first component may be referred to as a can cover, and the second component may be referred to as a can end.
The sub-components of the can end may be secured to each other in various ways. For example, the first component may be attached to the second component by way of an adhesive. For example, if the container will be used for foodstuffs or liquids, a Food and Drug Administration approved adhesive may be used. These components may also be secured to one another by mating complementary parts to one another. For example, mating may occur by matching up openings within the first component with raised portions, such as pins or pegs in the second component which are then flattened to secure the components to each other. The first component and second component may have edges that may be crimped to one another, for example, in the case of aluminum components. Snap hooks may alternatively be used to snap the first component into the second component. One or more tabs may be used to engage and hold the first and second components of the can end in place. The one or more tabs that are engaged to hold the first and second components in place may be held by being forced up against the inside one of the first and second component. Of course, those skilled in the art may recognize other means for securing the first and second components which may be used to assemble this portion of the closure system.
The closure system may comprise a component to secure the fixed element to the container body, and to retain the contents within the container to ensure the integrity of the contents. The component may be constructed and arranged to secure the fixed element to the container body. In certain examples, the component may be made as one piece as a part of the can end. As noted above, beverage containers of the present invention may be manufactured by commercially available processes with minimal retrofitting. The fixed element may comprise a component that may be mated and secured to the container body by conventional beverage can manufacturing processes. For example, the component may be mated with the container body to form a seam. The seam may be a double seam that provides a hermetic seal. In other examples, the component may be mated with the container body by snapping latches in one component or sub-component into the grooves of another component or sub-component. In certain examples, the component may be a rim. The rim may be constructed and arranged to secure the fixed element to the container body. The rim may be made of the same or different material as any one of the components of the container and/or closure system. The rim may have a perimeter that is the same or different shape as the perimeter of the top portion of the container body. For example, the rim may have a circular outer circumference, and may have a diameter the same as or larger than the diameter of the top portion of the container body. As noted above, the rim may be made as part of the can end. In certain other examples, the rim may be made as a separate component. The rim may comprise at least one opening. The opening may be constructed and arranged of a shape, size and material to ultimately allow the contents of the container to be dispensed smoothly and efficiently from the container. The opening may allow for a can end to fit within the opening.

The movable closure element may comprise one or more components that may be permanently or temporarily attached to each other. The movable closure element may comprise a component to cover the dispensing portion or an area of the fixed element larger than the dispensing portion, and retain the contents inside the container. In certain examples, the component may reveal the entire dispensing portion, or a section thereof. The component may be in contact with the fixed element at one or more points. The component may have the ability to move from a first position to one or more other positions to, for example, cover or reveal the dispensing portion. Moving may involve, for example, one or more of sliding, twisting, shifting, turning, pulling, pushing, transferring, removing, engaging or otherwise modifying the position of one or more components of the closure system, for example, the top cover. The component may reside outside the container and may serve as a top cover for the container. The top cover may be of various functional and/or ornamental shapes and sizes to provide protection to the dispensing portion from the environment and to retain contents within the container.
The top cover may comprise one or more sub-components to assist a consumer in moving the top cover. For example, this sub-component may assist the consumer in turning or twisting the top cover to a position, or assist the consumer in shifting or sliding the top cover to another position. The sub-component may be a grip which may include, for example, one or more of any of an edge, ridge, rim, notch, groove, cavity, depression, indentation, pitted or rough surface, ring or lever that is on, in or attached to the top cover suitable for assisting a consumer in moving the top cover as desired. The grip may be manufactured as part of the top cover, for example, in a molding process, or may be manufactured separately, to be mated with the top cover during manufacturing of the closure system. In certain examples, the grip may be a portion of the top cover that may be manipulated by the user into a position that may then allow for moving the top cover, for example, turning or shifting the top cover. The manipulation may be performed by flipping a portion of the top cover that is engaged with a hinge, which allows the portion of the top cover to move from a horizontal position to a vertical position, thereby forming a sort of handle, lever, or the like. The top cover may comprise a portion that may be mated with other portions of the movable closure element, which may, together, assist in the opening and closing of the container, and covering and revealing the dispensing portion using the closure system. The top cover may also comprise a portion that provides a seal between the top cover and the top surface of the fixed element. In certain examples, this portion may be a seal, such as a gasket or o-ring.
The top cover or fixed element may also comprise one or more components that allow a portion of the top cover to be secured to limit movement of the portion of the top cover. The one or more components may secure, lock, or fasten a portion of the top cover to another portion of the top cover. For example, a component of the top cover or fixed element may be constructed and arranged to mate with a portion of the top cover, such as a lever, to secure the lever in a position such that the lever is fixed in place or is secured in a resting position. A component of the top cover may be a groove that may mate with a snap hook on the lever to secure the lever in a resting position on the top cover. In another example a component of the top cover may be constructed and arranged to mate with another component of the top cover, to at least in part secure the top cover to the fixed element.
The movable closure element may also comprise a component to provide a seal and retain the contents in the container in conjunction with other components of the movable closure element. This component may provide a secure, reliable, leak-proof closure for the container. The component may also allow for dispensing of the contents from the container. The component may be a sealing portion comprising one or more components. The sealing portion may be of various functional and/or ornamental shapes and sizes to provide a seal for retaining contents inside the container. The sealing portion may also be of various functional and/or ornamental shapes and sizes to provide for a release of pressure from within the container, for example, if the contents within the container comprise a carbonated beverage. The sealing portion may reside within the container and have contact with the bottom surface of the can end. In certain examples, the sealing portion may reside within the container but not necessarily be in contact with the bottom surface of the can end. The sealing portion may provide for a seal for retaining contents inside the container, which may be enhanced by the internal pressure of the contents; however, the internal pressure is not required to provide the seal. The sealing portion may be constructed of materials that are compatible with the other components of the beverage container, and may also be constructed of materials that are compatible with the contents of the container. For example, the sealing portion may be constructed of a material that is inert or non-reactive with the contents of the container. In certain examples, the sealing portion may be made of polypropylene. Suitable shapes, sizes and materials for the sealing portion will be readily selected by a person of ordinary skill in the art, given the benefit of the disclosure. Other means may be used alternatively or in conjunction with the above described mechanical elements to secure the fixed element to the container body.
The sealing portion may comprise a sub-component that may assist with obtaining and maintaining the integrity of the seal of the container, initially, and after opening and during use by the consumer. The sub-component may enhance the sealing capability of the sealing portion. The sub-component may be manufactured separately from the sealing portion, or may be manufactured as part of the sealing portion. In the former circumstance, the sub-component may be mated with the sealing portion by various mating techniques discussed above, including the use of an adhesive, or through construction and arrangement of the sub-component and the sealing portion. The sealing portion may be constructed and arranged to accept the sub-component to ensure that the two components mate properly. For example, the sealing portion may contain a groove or other structure to accept the sub-component into the sealing portion. In the latter circumstance, the sub-component may be molded directly to the sealing portion through conventional molding processes. The sub-component may be an o-ring or gasket used to ensure a proper seal between the sealing portion and the bottom surface of the can end. The o-ring or gasket may be constructed of any suitable material to create such a seal, and that may be compatible with the other components of the closure system, such as the sealing portion and can end, as well as the contents of the container. For example, the o-ring may be made of a polymeric material that has a suitable flexibility to create the desired seal. The sealing portion and the sub-component may be made of the same material, as one piece, for example, an o-ring or gasket like material that may function as the sealing portion and as a seal.
The sealing portion may comprise one or more sub-components that may allow for release of pressure from within the container, for example, if the contents within the container comprise a carbonated beverage. The one or more sub-components may interact with other components or sub-components of the closure system to allow for release of pressure from within the container. The one or more sub-components may also participate in the sealing capability of the sealing portion. The sub-component may be manufactured separately from the sealing portion, or may be manufactured as part of the sealing portion. The one or more components can be of any suitable size or shape to accomplish release of pressure from within the container.
The one or more sub-components may form an opening in the sealing portion. The opening may be of any size or shape suitable for allowing any pressure from within the container to be released in a pre-determined desirable manner. The opening may extend through the entire thickness of the sealing portion. The diameter or width of the opening may be the same throughout the thickness of the sealing portion. In some examples, the diameter or width of the opening may decrease or increase throughout the thickness of the sealing portion, in a gradual or step-wise manner.
The sealing portion may also comprise an additional sub-component of the sealing portion that may allow for release of pressure from within the container, for example, if the contents within the container comprise a carbonated beverage. The sub-component may interact with other components or sub-components of the closure system to allow for release of pressure from within the container. The sub-component may also participate in the sealing capability of the sealing portion. The sub-component may be manufactured separately from the sealing portion, or may be manufactured as part of the sealing portion. For example, the sub-component may be manufactured as part of the sealing portion sub-component that may assist with obtaining and maintaining the integrity of the seal of the container, initially, and after opening and during use by the consumer, for example, the o-ring or gasket. The sub-component may be an over-mold that is constructed and arranged to be positioned within the opening of the sealing portion. The over-mold may comprise an opening that may align with the opening of the sealing portion to allow for release of pressure from within the container. The opening in the over-mold may also align with a portion of the top cover to allow for release of pressure from within the container. For example, as the lever of the top cover is lifted to a predetermined angle, the opening in the over-mold may align with an opening of the lever to allow for the release of pressure from within the container. A predetermined angle as discussed herein refers to an angle as measured between the bottom surface of a grip, for example a lever, and the horizontal plane extending across the fixed element or can end.
The over-mold may be mated with the sealing portion by various mating techniques discussed above, including the use of an adhesive, chemical or thermal bond, or through construction and arrangement of the sub-component and the sealing portion, such that an appropriate fit is achieved and an additional mating technique is not required. In certain examples, the pressure within the container may secure the over-mold in place within the opening of the sealing portion and up against another component of the closure system, for example the lever of the top cover. This may ensure a secure seal of the container prior to it being opened using the closure system. The over-mold may be molded directly to the sealing portion through conventional molding processes. The over-mold may be constructed of any suitable material to participate in adequate sealing of the closure system and release of pressure from within the container, and that may be compatible with the other components of the closure system, such as the sealing portion, top cover, can end, as well as the contents of the container. For example, the over-mold may be made of a polymeric material that has a suitable flexibility to create the desired seal. In certain examples, the over-mold may be made of a thermoplastic elastomer (TPE). If, for example the sealing portion, often referred to in the molding industry as a substrate, is made of polypropylene, and the over-mold is made of TPE, a thermal bond can be initiated between these two components by applying heat. The sealing portion and the one or more sub-components may be made of the same material, as one piece, for example, an o-ring or gasket-like material that may function as the sealing portion, a seal, and as a suitable opening for releasing pressure from within the container.
The sealing portion may comprise a sub-component that may allow for movement of the sealing portion in a given direction. The sub-component may also interact with other components of the closure system, such as the fixed element to prevent movement of the sealing portion in a different given direction. The sub-component may interact with other components of the closure system, such as the fixed element, can end, or channel guide to cover the dispensing portion, or to expose the dispensing portion. The sub-component may further be constructed and arranged to mate with or accept a component or sub-component of the fixed element. In one embodiment, the sub-component may be an aligner, guide, or connector to control the rate of adjustment of this sub-component to another component. For example, the sub-component may be a channel that may mate with a component of the fixed element, for example, the can end. The channel may mate with at least a portion of the channel guide of the can end. Alternatively, at least a portion of the channel may mate with the channel guide. The channel and channel guide may mate by various mechanisms. For example, the channel and channel guide may mate such that it allows for movement of the sealing portion relative to the channel guide. The movement of the sealing portion relative to the channel guide may be in the vertical direction, i.e., upwards or downwards. In certain embodiments, at least a portion of the sealing portion may move in a horizontal direction, parallel to the can end, without making contact with the can end during movement.
The channel or channel guide may contain a section that allows the sealing portion to move relative to each other, but that permits movement of the channel up to a certain predetermined distance. For example, the section of the channel or channel guide may be constructed and arranged to prevent the sealing portion from moving any further in a given direction. The section of the channel or channel guide may prevent the sealing portion from becoming separated from the other components of the closure system. The section may also prevent the sealing portion from falling into the container. These desired effects may be accomplished by mating or associating certain sub-components of at least one of the top cover, sealing portion, fixed element, or other components of the closure system with the channel or channel guide. In certain examples, at least one of the top cover or sealing portion may be associated with the channel guide such that at least a portion of the top cover or sealing portion may reside within the channel guide. The association may allow the top cover, for example, to glide along at least a portion of the channel guide, while restricting the movement of the top cover in other directions to maintain alignment of the top cover with the channel guide. The section of the channel or channel guide may comprise a device that may secure the sealing portion to the channel guide or the stem at a predetermined distance from the bottom surface of the can end. The section may comprise one or more snap-hooks to maintain the connection between the sealing portion and the other components of the closure system, such as the channel guide or the stem.
The movable closure element may also comprise a component that secures other portions of the movable closure element to each other. The component may allow for movement of the sealing portion together with the top cover. The component may allow for the movement of the sealing portion in a direction that is the same as the direction in which the top cover is moved. Alternatively, the component may allow for the movement of the sealing portion in a direction that is not the same as the direction in which the top cover is moved. The component may mate with the top cover and the sealing portion by the same or different mating methods. The component may be a stem, for example, that may be mated with the top cover and the sealing portion. The stem may be constructed and arranged to mate with the top cover by one mating method, and with the sealing portion by a different mating method. The stem may have a top end constructed and arranged to be mated with the top cover and a bottom end constructed and arranged to be mated with the sealing portion. The top end of the stem may mate with the top cover by extending through the dispensing portion and/or the channel guide of the can end. The mating of the top cover to the top end of the stem may ensure that movement of the stem occurs with movement of the top cover.
The stem may be mated with the top cover by way of various methods. In certain examples, the stem and top cover may be mated through the use of an adhesive. In other examples, snap hooks on either the top cover or the top portion of the stem may provide the mechanism for mating these two components. Yet in other examples, well-known techniques such as spin welding may be used to mate these two components, for example, if these components are constructed from polymeric materials. Mating these two components may include the use of a cross pin which would slide through holes in the top cover and top portion of the stem, to keep these two components in place. Other ways of mating involve crimping the two components to each other, using a rivet or otherwise.
The stem may be positioned within the channel of the sealing portion and may be constructed and arranged to mate with the sealing portion. The bottom end of the stem may be constructed and arranged to mate with a portion of the sealing portion in communication with the channel. The portion of the sealing portion may be constructed and arranged to accept and mate with the bottom end of the stem. The mating may be such that movement of the stem may cause movement of the sealing portion. In certain examples, a movement of the stem (for example in a horizontal direction) may cause movement of the sealing portion in a vertical direction, for example upward or downward. In one embodiment, rotation of the stem in one direction may cause movement of the sealing portion in a downward direction. Because the channel guide of the fixed element may be mated with the channel of the sealing portion, the sealing portion will not rotate with the stem, but instead will only move in a vertical direction. The bottom end of the stem may comprise a threaded surface that mates with a compatible threaded surface of the sealing portion. The bottom end of the stem may comprise a threaded surface having a female thread which is compatible with the threaded surface of the sealing portion having a male thread. Alternatively, the bottom end of the stem may comprise a threaded surface having a male thread which is compatible with the threaded surface of the sealing portion having a female thread. The stem may be of various functional and/or ornamental shapes and sizes to secure the desired components of the closure system together. It will be within the ability of the person of ordinary skill in the art, given the benefit of the disclosure, to select or to design suitable shapes, sizes and materials of the stem disclosed herein.
The component of the movable closure element that secures other portions of the movable closure element to each other may be a sub-component of at least one of the top cover and the sealing portion. As described above, this component may allow for movement of the sealing portion together with the top cover, for example in a horizontal or vertical direction. The component may allow for the movement of the sealing portion in a direction that is the same as the direction in which the top cover is moved. In addition, the component may allow for the movement of the sealing portion in a direction that is not the same direction as the direction in which the top cover is moved. For example, engaging the top cover can cause the sealing portion to move in a vertical direction. The component may be a lever receiving portion that may be attached to the sealing portion, or may be manufactured as a part of the sealing portion. The lever receiving portion may be constructed and arranged to accept another component of the movable closure element such as the top cover. By allowing the lever receiving portion to interact with the top cover, the closure system may suitably operate to allow for various opened and closed positions of the closure system. For example, the lever receiving portion may be constructed and arranged to accept the lever of the top cover. By moving the lever, which may operatively interact with the lever receiving portion, a user may operate the closure system to expose or cover the dispensing portion as desired.
In some embodiments, aspects of the lever receiving portion may comprise a structure to secure a portion of the top cover, for example a portion of the lever, to allow the lever to pivot relative to other portions of the top cover or sealing portion. This aspect of the lever receiving portion may receive a portion of the lever, such as a pin, allowing the components of the movable closure element to mate or cooperate with one another. The lever receiving portion and the lever can be designed to be any suitable shape, size and material such that these components may communicate with one another to allow the top cover and sealing portion to operatively interact and move in one or more desired directions.
In certain embodiments, the lever receiving portion may form an opening that may accept the pin of the lever to allow for movement of the sealing portion during operation of the closure system. The shape of the opening may be the same or different from the shape of the cross-section of the pin. In some examples, the shape of the opening may complement the shape of the cross-section of the pin to push or pull the sealing portion in a vertical direction, for example in a downward direction.
In this embodiment, in the closed position, the opening and the cross-section of the pin are constructed and arranged such that the pin contacts a portion of the lever receiving portion on a surface of the opening and also contacts the over-mold, such that there is no communication between the environment within and outside of the container. In this way, these components function as a valve for the closure system, wherein the movement of the pin relative to the lever receiving portion and the over-mold may allow for communication between the interior and exterior environment of the container. As the pin is rotated, by moving a grip, for example a lever, in a given direction, an opening in the pin may become aligned with the opening in the over-mold, thereby opening the valve, so as to initiate a release of any pressure within the container. Once the pressure has been released, the shape of the opening and the cross-section of the pin allow the pin to communicate with the over-mold, which initiates movement of the sealing portion in a downward direction. As the pin continues to rotate, the shape of the opening and the cross-section of the pin may prevent the grip, for example, the lever, from being moved further in the given direction. These actions may be reversed by moving the grip, for example, the lever, in a direction opposite the given direction, pulling up the sealing portion and blocking the opening of the over-mold using the pin, thereby closing the valve.
The movable closure element may also comprise a component that may provide an indication that the container has been at least partially opened or otherwise tampered with or altered. The component may provide an indication that the original seal from the manufacturer has been broken such that a user may assess the safety of the contents of the container, or whether the contents of the container have been altered. The indication may be any indication that notifies the user that the manufacturing seal has been at least partially broken, for example by movement of the component, or change in color of the component. The component can be a sub-component of the top cover, sealing portion, fixed element, or a combination thereof. For example, the sub-component can be a portion of the top cover, such that when a portion of the top cover or another portion of the closure system is manipulated in some way, the sub-component may indicate that the container has been at least partially opened, tampered with or altered. In certain examples, the sub-component may be a member of the top cover that is in communication with the lever. As the lever is lifted, the member may move from its original position, thereby indicating that the container has been at least partially opened or otherwise tampered with or altered.
To facilitate stacking of the containers for more convenient and cost-effective shipping and storing, the top of the container comprising a closure system may be constructed and arranged to accept the bottom of another container body, or the base plate attached to another container body. For example, the top cover of the closure system may reside below the top edge of the fixed element which mates with the container body such that the top cover does not interfere in the stacking of multiple containers on top of one another. In other examples, a side of the container body may be constructed and arranged to accept a side of another container body to facilitate stacking of the containers.
A container body may be provided of various functional and/or ornamental shapes and sizes suitable for holding, storing, handling, and/or cooling or heating the contents of the beverage container. Conventional manufacturing processes as described above are used for producing beverage can bodies may be used for providing a container body. The closure system may be disposed on the container body by placing, dropping, depositing, or the like. This may be accomplished through automated processes or manually. Securing may occur to ensure the integrity of the contents of the container through mating of the container body to the closure system. Mating may occur between the container body and the fixed element. Mating may also occur between various components and sub-components of the closure system and container body. The securing may also occur using conventional methods of manufacturing beverage cans, for example, by forming a double seam. A flange of the fixed element may curl around a first edge of the container body to form a partial seam. The partial seam may be crimped and flattened for form a hermetic seal.
To assemble the beverage container, by automatic processes or manually, all or part of the closure element may be pre-assembled to be mated with the container body or inserted through the container body and may be compatible with conventional manufacturing processes of an aluminum can. Alternatively, portions of the fixed element may be mated to each other and the container body without being pre-assembled.
The operation of the assembled closure system of a container is described below. In one embodiment, at a first position, the top cover covers the dispensing portion and may also cover a portion of the can end. At this first position, the sealing portion is in contact with a bottom surface of the can end in a locked position, and the stem is positioned at the first end of the channel guide. The stem may be mated to the top cover by any various means, including those described above such that as the top cover is moved, the stem moves in the same direction.
The user may use one or more of the grips of the top cover to move the top cover in a desired direction, for example, to a second position. As the top cover is moved in a desired direction, due to the mating of the top cover and the top end of the stem, the stem is moved in the same desired direction. Because the bottom end of the stem is mated with the sealing portion, this causes the sealing portion to move. For example, the bottom end of the stem may have a threaded surface that is compatible with the threaded surface of a portion of the sealing portion, which, upon movement of the top cover would thereby move the sealing portion along the threaded surface. For example, movement of the top cover would move the sealing portion along the threaded surface in a vertical downward direction away from the bottom surface of the can end. The closure system may be constructed and arranged to prevent the sealing portion from moving further away than a pre-determined distance from the bottom surface of the can end to an unlocked position at the first end of the channel guide.
The channel may contain a section that allows the sealing portion to move relative to the channel guide, but that permits movement of the channel up to a certain predetermined distance. For example, the section of the channel may be constructed and arranged to prevent the sealing portion from moving any further in a given direction. The section of the channel may prevent the sealing portion from becoming separated from the other components of the closure system. The section may also prevent the sealing portion from falling into the container. The section may comprise a device that may secure the sealing portion to the channel guide or the stem at a predetermined distance from the bottom surface of the can end. The section may comprise one or more snap-hooks to maintain the connection between the sealing portion and the other components of the closure system, such as the channel guide or the stem.
The user may again use one or more of the grips of the top cover to move the top cover in a desired direction, for example, to a third position. As the top cover is moved in a desired direction, due to the mating of the top cover and the top end of the stem, the stem is moved in the same desired direction. Because the bottom end of the stem is mated with the sealing portion, this in turn causes the sealing portion to move. At the third position the top cover exposes the dispensing portion, the sealing portion is spaced a predetermined distance from the bottom surface of the can end, and the stem is positioned at the second end of the channel guide.
The user may use one or more of the grips of the top cover to move the top cover in a desired direction, for example, to a fourth position. As the top cover is moved in a desired direction, due to the mating of the top cover and the top end of the stem, the stem is moved in the same desired direction. This desired direction may be opposite the direction that the top cover and top end of the screw are moved when transitioning from the first position to the second position. In moving to this fourth position, the sealing portion comes into contact with the bottom surface of the can end in a locked position, and the stem is positioned at the second end of the channel guide. In certain examples, a sub-component of the sealing portion comes into contact with the bottom surface of the can end. The sub-component may be an o-ring or gasket.
From the second position, the user may use one or more of the grips of the top cover to move the top cover in a desired direction, for example, to a fifth position. As the top cover is moved in a desired direction, due to the mating of the top cover and the top end of the stem, the stem is moved in the same desired direction. Because the bottom end of the stem is mated with the sealing portion, this in turn causes the sealing portion to move. At a fifth position the top cover exposes at least a portion of the dispensing portion, the sealing portion is spaced a predetermined distance from the bottom surface of the can end, and the stem is positioned at a predetermined distance from the first end of the channel guide.
From the fifth position, the user may use one or more of the grips of the top cover to move the top cover in a desired direction, for example, to a sixth position. As the top cover is moved in a desired direction, due to the mating of the top cover and the top end of the stem, the stem is moved in the same desired direction. This desired direction may be opposite the direction that the top cover and top end of the screw are moved in when transitioning from the first position to the second position. In moving to this sixth position, the sealing portion comes into contact with the bottom surface of the can end in a locked position, and the stem is positioned at a predetermined distance from the first end of the channel guide. In certain examples, a sub-component of the sealing portion comes into contact with the bottom surface of the can end. The sub-component may be an o-ring or gasket.
In another embodiment, at a first position, the top cover covers the dispensing portion and may also cover a portion of the can end. At this first position, the lever of the top cover is resting on the top cover, and the sealing portion is in contact with a bottom surface of the can end in a locked position.
The user may use the lever of the top cover to move the top cover in a desired direction, for example, to a second position. As the lever is moved in a desired direction, for example, as the lever is lifted relative to the first position, due to the mating of the top cover and the sealing portion, the sealing portion is spaced a predetermined distance from the bottom surface of the can end. If the contents of the container are sealed under pressure, the pressure is released from the container during transition from the first position to the second position.
The user may again use the lever of the top cover to move the top cover in a desired direction, for example, to a third position. As the top cover is moved in a desired direction, the sealing portion is also moved in the same desired direction. At the third position the top cover exposes the dispensing portion and the sealing portion is spaced a predetermined distance from the bottom surface of the can end.
The user may use the lever of the top cover to move the top cover in a desired direction, for example, to a fourth position. As the lever is moved in a desired direction, for example, as the lever is lowered, the sealing portion comes into contact with the bottom surface of the can end in a locked position. In certain examples, a sub-component of the sealing portion comes into contact with the bottom surface of the can end. The sub-component may be an o-ring or gasket.
From the second position, the user may use the lever of the top cover to move the top cover in a desired direction, for example, to a fifth position. As the top cover is moved in a desired direction, due to the mating of the top cover and the sealing portion, the sealing portion also is moved in a desired direction. At a fifth position the top cover exposes at least a portion of the dispensing portion, and the sealing portion is spaced a predetermined distance from the bottom surface of the can end.
As the lever is moved in a desired direction, for example, as the lever is lowered, the sealing portion comes into contact with the bottom surface of the can end in a locked position. In certain examples, a sub-component of the sealing portion comes into contact with the bottom surface of the can end. The sub-component may be an o-ring or gasket.
In another embodiment, a closure system is configured to seal a container constructed and arranged to be mated with a container body. In a particular embodiment, the closure system includes a can end having a dispensing portion and a channel guide formed therein. The channel guide includes a first end and a second end. The can end is constructed and arranged to be secured to an end of the container body. The closure system further includes a movable closure element having a top cover and a sealing portion. The top cover has a lever and the sealing portion has a lever receiving portion, which is constructed and arranged to accept the lever. The arrangement is such that, as the lever is lifted, the sealing portion moves in a downward direction away from the can end, and as the top cover is moved horizontally from the first end of the channel guide to the second end of the channel guide the dispensing portion is exposed.
The top cover is movable from first, second, third, fourth, fifth and sixth positions. In the first position, the top cover covers the dispensing portion and the lever of the top cover rests on the top cover, with the sealing portion being in contact with a bottom surface of the can end. In the second position, the top cover covers the dispensing portion and the lever is lifted relative to the first position, with the sealing portion being spaced a predetermined distance from the bottom surface of the can end. In the third position, the top cover and the sealing portion expose the dispensing portion, with the sealing portion being spaced a predetermined distance from the bottom surface of the can end. In the fourth position, the top cover and the sealing portion expose the dispensing portion, with the lever being lowered to rest on the top cover and the sealing portion being in contact with the bottom surface of the can end. In the fifth position, the top cover and the sealing portion expose at least a portion of the dispensing portion, with the lever of the top cover being lifted relative to the fourth position and the sealing portion being spaced a predetermined distance from the bottom surface of the can end. In the sixth position, the top cover and sealing portion expose at least a portion of the dispensing portion, with the lever of the top cover being lowered relative to the fifth position and the sealing portion being in contact with the bottom surface of the can end.
In certain embodiments, the can end is made of a material that is compatible with a material of at least one of the top cover and the sealing portion. Specifically, at least one of the top cover and the sealing portion is made of a polymeric material. The total weight of the polymeric material may be less than or equal to 10 grams.
In other embodiments, the lever may be constructed and arranged to operatively interact with the lever receiving portion. The top cover may be constructed and arranged to at least partially secure the top cover to the fixed element, and to mate with the lever. The top cover may be constructed and arranged to mate with another portion of the top cover and to at least partially secure the top cover to the fixed element. The top cover may be constructed and arranged to maintain alignment of the top cover with the channel guide. The arrangement is such that contents within the container are pressurized and the sealing portion is constructed and arranged to release pressure from within the container. The lever is configured to operatively interact with the sealing portion to release pressure from within the container. Specifically, pressure is released from the container when the lever is lifted from a resting position on the top cover to a predetermined angle. The arrangement is such that as the lever is lifted, a portion of the lever becomes aligned with the sealing portion to release pressure from within the container.
In a further embodiment, a closure system is configured to seal a container constructed and arranged to be mated with a container body. In a particular embodiment, the closure system includes a can end having a dispensing portion and a channel guide. The can end is constructed and arranged to be secured to an end of the container body. The closure system further includes a movable closure element having a top cover and a sealing portion. In one embodiment, the top cover includes a grip and the sealing portion operatively interacts with the top cover. The arrangement is such that as the top cover is engaged, the sealing portion moves in a vertical direction, and as the top cover is moved in a horizontal direction along the channel guide, the sealing portion moves in the horizontal direction.
Referring now to the figures, in one embodiment, FIGS. 1A-1C illustrate a beverage container 10 in which a container body 100 made from a conventional manufacturing process is used. Container body 100 is attached to closure system 102. Closure system 102 comprises a fixed element 104 and a movable closure element 106 (shown in FIGS. 2A and 2B). FIG. 1A is a perspective view of the beverage container and illustrates a beverage container 10 in the closed position. FIG. 1B is a perspective view of the beverage container, and illustrates a beverage container 10 in a partially opened position with top cover 118 partially exposing dispensing portion 114. FIG. 1C is a perspective view of the beverage container, and illustrates a beverage container 10 in a fully opened position with top cover 118 fully exposing dispensing portion 114.
As illustrated in the exploded views of FIGS. 2A and 2B, closure system 102 of beverage container 10 of FIGS. 1A-1C comprises multiple components. As shown, fixed element 104 comprises can end 108 having dispensing portion 110. In this embodiment, fixed element 104 also comprises can cover 112 comprising dispensing portion 114 and channel guide 116. Fixed element 104 may be assembled by placing can cover 112 on can end 108, aligning dispensing portion 114 with dispensing portion 110, and aligning channel guide 116 with dispensing portion 110.
Closure system 102 of FIGS. 2A and 2B also comprises a movable closure element 106. As shown, movable closure element 106 comprises top cover 118 having grip 119 to assist a user in opening and closing the container. Movable closure element 106 also comprises stem 122 and sealing portion 120 having channel 150. Movable closure element 106 may be assembled by inserting top end 124 of stem 122 through dispensing portion 110 and channel guide 116 so that top end 124 of stem 122 can mate with opening 126 in top cover 118. Sealing portion 120 can be mated with gasket 128 to ensure a tight seal between the sealing portion and the bottom surface 130 of can end 108. This may be accomplished by aligning members 132 with openings 134 of sealing portion 120. Other various means of attaching gasket 128 to sealing portion 120 may be used as discussed above. Sealing portion 120 may be mated with stem 122, by mating bottom end 136 of stem 122 having threaded surface 138 with threaded section 140 of sealing portion 120. The mating of threaded surface 138 with threaded section 140 allows sealing portion 120 to move vertically, i.e., upwards or downwards relative to fixed element 104.
In one embodiment, FIGS. 3A-3D illustrate one way that a two-component fixed element may be assembled. FIG. 3A illustrates can cover 112 comprising dispensing portion 114 and channel guide 116. FIG. 3B illustrates can end 108 comprising dispensing portion 110. To assemble the fixed element as shown in FIGS. 3C and 3D, an adhesive, for example a Food and Drug Administration approved adhesive, may be applied to a bottom surface of can cover 112 and/or top surface of can end 108. Can cover 112 and can end 108 may then be mated by aligning dispensing portion 114 and channel guide 116 of can cover 112 with dispensing portion 110 of can end 108. This allows channel guide 116 to reside below the surface of can end 108 through dispensing portion 110 of can end 108, as shown in FIG. 3D.
In another embodiment, FIGS. 4A-4D illustrate another way that a two-component fixed element may be assembled. FIG. 4A illustrates can cover 112 comprising dispensing portion 114, channel guide 116 and openings 142. FIG. 4B illustrate can cover 108 comprising dispensing portion 108 and pegs 144.

Once can cover 112 is in place on top of can end 108, pegs 144 are flattened against can cover 112 and can end 108 to form flattened pegs 146 which secure these two pieces in place to form the fixed element, as shown in FIGS. 4C and 4D.
In another embodiment, FIGS. 5A-5E illustrate another way that a two-piece fixed element may be assembled. FIGS. 5A and 5B illustrate can cover 112 comprising dispensing portion 114, channel guide 116, and lip 148 having crimping groove 151. FIGS. 5C and 5D illustrate can end 108 comprising dispensing portion 110 and overhang 152 having crimp line 154. To assemble fixed element 104 as shown in FIG. 5E, lip 148 and overhang 152 are joined in and crimped together to form a crimped portion 156 of fixed element 104.
In another embodiment, snap hooks may be used to mate the components of the two-component fixed element. It will be within the ability of the person of ordinary skill in the art, given the benefit of the disclosure, to select or to design suitable shapes, sizes and materials for mating the components of the fixed element together.
In yet another embodiment as shown in FIGS. 6A and 6B, the fixed element may be constructed as one piece. In this embodiment, fixed element 204 may be made of aluminum. Can end 208 comprises dispensing portion 214 and channel guide 216. In this embodiment, the starting material for can end 208 may be produced from conventional manufacturing processes from which dispensing portion 214 and channel guide 216 may be formed. This embodiment requires no can cover and streamlines the process of producing fixed element 204 for the closure system.
FIGS. 7A-8B illustrate perspective views of a portion of the closure system in accordance with certain embodiments. FIGS. 7A and 7B illustrate top cover 118 having grip 119, fixed element 104 having channel guide 116 and dispensing portion 110, and stem 122 having top end 124 and bottom end 136 prior to assembly. As shown, stem 122 is inserted into channel guide 116 of fixed element 104. Top end 124 of stem 122 is mated with opening 126 of top cover 118. Mating of these two components can be achieved by snap hooks 170 of top end 124 of stem 122 being inserted into grooves 172 of opening 126 of top cover 118, or by other various mating means as discussed above. FIGS. 8A and 8B illustrate this assembled portion of the closure element, from the top and bottom perspective views.
FIGS. 9A-9F illustrate various other methods for assembling the top cover, stem, and fixed element (not shown in FIGS. 9A-9F) together. For example, FIG. 9A again illustrates the use of snap hooks 370 of top end 324 of stem 322 which can mate with grooves 372 of opening 326 of top cover 318. FIG. 9B illustrates the use of an adhesive which may be applied to top end 424 of stem 422, to opening 474 of top cover 418, or to both top end 424 and opening 474 to achieve the mating of these components. Spin welding may also be used to mate these components as shown in FIG. 9C. In another embodiment, fastener 676 may be inserted through openings 678 of top cover 618 and openings 680 of top end 624 of stem 622. FIG. 9E illustrates pre-crimped rivet 782 which is inserted into opening 726 of top cover 718. Fixed element (not shown) is placed below top cover 718, followed by stem 722 which is inserted into opening 774 along with washer 786. Once each of these components is in place, pre-crimped rivet 782 is crimped, as shown in 784 to mate the components together. In another example, FIG. 9F illustrates stem 822 which may be inserted into opening 884 so that these components may be crimped together at crimping area 888 of top cover 818 and crimping groove 890 of stem 822. It will be within the ability of the person of ordinary skill in the art, given the benefit of the disclosure, to select or to design suitable mating configurations for the components of the closure element as disclosed herein.
Once stem 136, top cover 118 and fixed element 104 are assembled, sealing portion 120 may be attached as shown in FIGS. 10A and 10B. Gasket 128 can be secured to sealing portion 120 by aligning members 122 with opening 134 of sealing portion 120. Once gasket 128 is in place, sealing portion 120 is screwed into place by mating bottom end 136 of stem 122 with threaded section 140 of sealing portion 120. This completes assembly of the closure element, which is now ready to be mated with a container body in one of the various ways described above, or by any other suitable means.

Turning now to FIGS. 44A, 44B, 44C, 44D and 44E, the movement of the middle finger 1132 with respect to the body 1134 of the sealing portion 1118 is illustrated. FIGS. 44A and 44B illustrate the middle finger 1132 in an extended position. It should be understood that the middle finger 1132 may sometimes be referred to as a valve, which will be apparent as the description of the closure system 1100 proceeds. The middle finger 1132 includes a flexible hinge 1140 that enables the movement of the finger. FIGS. 44C, 44D and 44E illustrate the middle finger 1132 in the position in which the middle finger extends between the outer fingers 1128, 1130. Referring particularly to FIG. 44D, each finger 1128, 1130 and 1132 includes a surface 1142 formed by a widening of the finger. The surfaces 1142 are configured to engage the portion 1136 of the lever 1122 when the lever is pivotably secured to the top cover 1116. As shown, the surface 1142 of the middle finger 1132 is elevated relative to the surfaces 1142 of the outer fingers 1128, 1130. Referring now to FIG. 44E, the middle finger 1132 includes a valve 1144 that is received within a valve seat 1146 formed in the bottom surface 1138 of the sealing portion 1118.
Referring to FIGS. 45A and 45B, the surface 1142 of the middle finger 1132 is shown to be at the same elevation as the surfaces 1142 of all of the outer fingers 1128, 1130. This movement is achieved by the engagement of the portion 1136 of the lever 1122 when the lever is pivoted in the manner described above. This movement of the lever 1122 results in the downward motion of the middle finger 1132 relative to the outer fingers 1128, 1130. As shown in FIG. 45B, the valve 1144 is moved away from the valve seat 1146 thereby creating a space 1148 between a body portion 1150 of the middle finger 1132 and the sealing portion 1118. This space 1148 enables an initial release of pressure of the contents of the container body when opening the movable closure element 1104 by initially pivoting the lever 1122. The body 1134 of the sealing portion 1118 may include a rubber seal (not designated) to create a sealing engagement of the sealing portion with the bottom surface 1138 of the can end 1102. Additionally, the valve seat 1146 may include a rubber overmold to create a sealing engagement of the valve 1144 with the valve seat.
FIGS. 46A and 46B illustrate the top cover 1116 having the body 1120. In one embodiment, the body 1120 of the top cover 1116 further includes a pair of first latch elements, each indicated at 1152, and a second pair of latch elements, each indicated at 1153, configured to secure the lever 1122 to the top cover. The body 1120 of the top cover 1116 includes a pair of slots, each indicated at 1154, which are disposed between respective latch elements 1152, 1153. The slots 1154 are configured to receive end elements, each indicated at 1156, of the lever 1122 when pivoting the lever. The slots 1154 serve as guides for the end elements 1156 of the lever 1122 when pivoting the lever from its flush position to its fully pivoted position.
Referring to FIG. 46B, the body 1120 of the top cover 1116 further includes two snap hooks, each indicated at 1158, which attach the top cover 1116 to the can end 1102 as the snap hooks enter into the channel guide 1110. The snap hooks 1158 also glide along the channel guide 1110 as the top cover 1116 moves horizontally along the channel guide to maintain alignment of the top cover with the channel guide. The notches 1126 provide some flexibility to the snap hooks 1158 when inserting the snap hooks into the channel guide 1110.
Specifically, with reference to FIGS. 47A, 47B, 47C, 47D and 47E and to FIGS. 48A, 48B, 48C and 48D, the pivotal connection of the lever 1122 to the top cover 1116 and the manner in which the lever pivots relative to the top cover is illustrated. The end elements 1156 are received within their respective slots 1154 formed in the body 1120 of the top cover 1116. This configuration enables the lever 1122 to rotate or pivot with respect to the top cover 1116. The latch elements 1152, 1153 are designed to provide a guide for the lever 1122 as the lever pivots. FIGS. 47B and 48A illustrate the lever 1122 resting on the top cover 1116. FIGS. 47C and 48B illustrate the lever 1122 pivoting away from the top cover 1116 short of a vertical position with the end elements 1156 entering into their respective slots 1154. FIGS. 47D and 48C illustrate the lever 1122 in a vertical position with respect to the top cover 1116. And FIGS. 47E and 48D illustrate the lever 1122 beyond a vertical position with respect to the top cover 1116.
The arrangement is such that the portion 1136 of the lever 1122 is designed to push down on the surfaces 1142 of the fingers 1128, 1130 and 1132. When the lever 1122 is swiveled toward an open (pivoted) position, the portion 1136 applies a downward force on the surface 1142 of the middle finger 1132 to move the valve 1144 from the valve seat 1146. Once the surfaces 1142 of the fingers 1128, 1130 and 1132 are level with one another, the portion 1136 moves the sealing portion 1118 downwards.
The assembly of the closure system 1100 is as follows. Referring to FIGS. 49A, 49B and 49C, the top cover 1116 is secured to the can end 1102 by inserting the snap hooks 1158 into the channel guide 1110 of the can end.
