     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. 
     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 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 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, or other consumable.

     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. 
     In a two-component can end, the first component may have a dispensing portion and the second component may have a dispensing portion. 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 beverage 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 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 protions, 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 fit within the opening. The opening may be a pre-determined shape, for example, the opening may be in the shape of a circle that is centered with respect to the outer perimeter of the rim. In other examples, the opening may be off-set with respect to the outer perimeter of the rim. The shape of the opening may be the same or different shape as the outer perimeter of the rim. The shape of the opening of the rim may be the same or different shape as the outer perimeter of the spout. 
     The closure system may comprise a component that provides a closure to the beverage container. The component may ensure the integrity of the contents and enclose the contents of the container, without risk of contamination, during holding, storing, shipping, dispensing, and/or cooling or heating the contents by, for example, the manufacturer, the distributor and/or the consumer. Additionally, the component may protect the dispensing portion of the container from the environment, thereby ensuring sanitary conditions until a user opens the container. The component may also protect the portion of the container from the environment after opening, as desired by the user. The component may work together with the fixed element to provide for a secure closure that ensures the integrity of the contents of the container, without the risk of contamination. The component may be a movable closure element that may seal off the contents of the container from the environment. The movable closure element may seal off the contents of the container initially, and, subsequent to opening, may be used again to seal off contents and further protect the dispensing portion from the environment. The movable closure element may be constructed and arranged to mate with one or more components of the fixed element, the container body or both. In certain examples, the movable closure element may be constructed and arranged to be mated with the dispensing portion and/or the bottom surface of the can end. The movable closure element may be constructed and arranged to be used in a locked or unlocked position. The movable closure element may be of various functional and/or ornamental shapes and sizes to be mated with the other components of the closure system and/or container body, and may be constructed of a material suitable for such purposes. The movable closure element may be sized and shaped to facilitate opening and closing of the container. The movable closure element may provide a surface for indicia for labeling the contents of the container, for marketing purposes, to facilitate opening of the container, or the like. At least a portion of the movable closure element may provide a surface that is easily printed on using conventional printing methods. 
     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, 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 over 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 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, 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 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 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 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. 
     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. 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 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. 
     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. 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. 
     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.

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 .
