Definitions
- the present invention relates to a closure member for an open end of a container, and more particularly to a resealable closure with a lid and a sealing flap mounted to the lid for closing a dispensing port provided in the lid.
- the invention further relates to resealable closures that utilize a combination of initial mechanical interference and pressure differential to achieve and maintain a tight, reliable seal of a dispensing port of a beverage container.
- the prior art includes a large number of containers for accommodating various types of goods, including beverages and other liquids.
- Such containers typically include a cylinder with an integrally formed bottom and an open top. They also include a closure that normally closes the open top and defines a sealed port through which one may discharge the contents of the container after breaking the seal .
- Some of the closures include resealable dispensing ports that allow a user to repeatedly open and close the port .
- a resealable closure should have a rugged, simple and inexpensive construction that allows repeated closing and opening while maintaining a tight seal even when the container holds pressurized fluid. It should allow easy opening, and it should simulate the local shape and lip feel of a drinking glass .
- a resealable closure should also keep the area that the lips contact clean by shielding it from environmental dirt or dust . It should further minimize slosh and facilitate pouring.
- most of the inventions previously proposed to enable resealing a carbonated beverage container in order that a portion of the contents could be saved for a later time have proposed using a variation on a bottle cork-- i.e., they involve inserting some kind of stopper into the dispensing port created by pushing in a scored portion of the metal end at the time of initial opening. None of these inventions have been commercially successful. The problem is that the carbonated beverage will emit a gas that exerts a force in the direction to dislodge the stopper from the opening.
- the pressure could exert a force of between forty and fifty pounds. If the stopper is jammed into the opening with sufficient mechanical interference to resist such a high force, it will not be possible for the average consumer to remove the stopper at normal use temperatures . In the design of conventional easy-open metal can ends, it is assumed that the consumer can exert a force no larger than 8 pounds .
- One embodiment of the present invention avoids the above problem by using a sliding motion that is nearly perpendicular to the primary vertical force generated by the internal pressure. There are two basic limitations with this design. The first is that, because of the creep tendencies of the plastic materials most suitable for such flaps, the flaps must be fairly thick in order to resist the forces generated by the internal pressure. The second is that the internal pressure creates a high friction force that resists the sliding of the flap.
- a venting port means a hole or other means of communication between the inside of the container and the outside environment. This would require the consumer to first remove this small venting plug and then, in a separate action, remove the component that seals the dispensing port. It would be more desirable if the same action that initially vents the can could, when continued, open the dispensing port.
- a closure member for closing an open end of a container includes a main body segment, or lid, secured to edge portions of a beverage container adjacent the open end and a moveable sealing flap mounted to the lid.
- the lid includes a discharge port, or dispensing port, through which fluid discharges from the container.
- the sealing flap is moveable between a first position in which it seals the dispensing port, and a second position away from the dispensing port.
- the sealing flap slides over the lid as it moves from the first to the second position.
- the sealing flap lies rotatably mounted to the lid, and a sealing liner or gasket lies between the lid and the sealing flap to assure a fluid-tight seal between these two segments.
- a sealing flap is used to block the dispensing port of a beverage container in such a way that a pressure differential, i.e. the difference between the internal pressure of a beverage container and the surrounding atmosphere, enhances a seal of the dispensing port.
- a pressure differential i.e. the difference between the internal pressure of a beverage container and the surrounding atmosphere
- the internal pressure of the container assists in forcing the sealing flap into a sealed engagement with the perimeter of the dispensing port.
- the external drive means of the resealable closure of the present invention provides a means to actuate the sealing flap between a sealed and an unsealed position, and also serves as the dust cover. It is further recognized that it would be advantageous to vent internal pressure of the beverage container prior to unsealing the dispensing port.
- a particular advantage of the present invention is that the forces necessary to initially vent the pressure in order to generally equalize the internal pressure with the surrounding atmospheric pressure are much lower in the various embodiments now disclosed, as compared to many conventional beverage containers, including bottles, because with these new resealable closures, venting is achieved prior to initial movement of the sealing flap.
- a further advantage is that any relatively high forces that must be exerted by a user on the external drive means in order to overcome the initial mechanical interference that had been used to initiate the seal between the sealing flap and the perimeter of the dispensing port on the underside of the lid need only be exerted for a relatively short interval of time. This is an important improvement over beverage container lids that would require the user to exert high forces throughout the entire duration of travel of the drive means to overcome forces from mechanical interference .
- venting means While re- sealing of the venting means may take place after re- sealing of the dispensing port, it is most desirable if the venting means is re-sealed prior to, or at least during, re-sealing of the dispensing port, so that a user does not forget to re-seal the vent once the dispensing port is re-sealed.
- the venting means is closed subsequent to re-sealing of the dispensing port, it is desirable to provide a tactile and/or audible reminder that activates upon re-sealing of the venting means, such that a user is assured both the dispensing port and the venting means are re-sealed.

While the following disclosure describes the invention in connection with various embodiments and modifications of those embodiments, one should understand that the invention is not limited to these embodiments and modifications. Furthermore, one should understand that the drawings are not to scale and that graphic symbols, diagrammatic representatives, and fragmentary views, in part, illustrate the embodiment. In certain instances, the disclosure may not include details which are not necessary for an understanding of the present invention such as conventional details of fabrication and assembly.
- the resealable closure of the present invention shown generally at 10 closes an open top of a beverage container 12.
- the beverage container 12 may be a wide mouth plastic enclosure, a metal can, or any other enclosure made of any suitable material .
- the resealable closure 10 may be a one-piece, integrally formed unit or component made out of a single or multi-layered plastic material such as polyolefin or polypropylene, PET, or any other suitable material that provides a gas barrier and has sufficient strength, flexibility and corrosion resistance.
- the resealable closure 10 includes a lid 18 and a sealing flap 22 moveably mounted to the lid.
- a first embodiment of the present invention includes a resealable closure 10 having a main body segment, or lid 18, with a rim portion
- connection between the sealing flap 22 and the lid 18 is a single pivot 150 about the center of the resealable closure 10 and the container 12.
- This pivot includes a knob portion of the sealing 22 flap and a cooperating well of the lid 18.
- the sealing flap 22 lies rotatably connected to the lid 18. The sealing flap 22' rotates from a first position shown in FIG. 1, counterclockwise to a second position shown in FIG. 4, away from a discharge port or dispensing port 20 in the . lid 18.
- the sealing flap 22 covers the dispensing port 20; and a continuous sealing liner 127 disposed in a groove 124g and secured to the sealing flap 22 forms a fluid-tight seal around the dispensing port 20.
- the liner 127 is a resilient member made out of rubber or any other suitable material .
- the lid 18 includes a stop portion 123i that engages a side of the sealing flap 22 to stop further clockwise rotation of the sealing flap 22 beyond the position shown in FIG. 1, and exert a force downwardly toward the perimeter of the dispensing port 20 in the lid 18 of the beverage container 12, that can initiate and help maintain the seal between the flap segment and the main body segment.
- the lid 18 also includes a breakable projection 123j which the sealing flap 22 breaks, but does not detach, the first time that the sealing flap 22 rotates from the first to the second position. (This feature evidences any tampering with resealable the closure 10. )
- the sealing flap 22 may include a handle portion (not shown) used to drive the segment between the first and the second positions and to add rigidity to the sealing flap 22.
- the first embodiment shown in FIGS. 1-5 also includes grooves in the rim portion of the lid 18 and cooperating threads on the inside of the rim portion of the sealing flap 22. This threading forces the sealing flap 22 inwardly of the beverage container 12 as the sealing flap 22 moves from the second to the first position. This action provides a better seal between the main body segment and the flap segment. It supplements the sealing force provided by the stop portion 123i.
- "snap-on" type procedures make the connection between the closure 10 and the beverage container 12.
- "Snap-on” type procedures include conventional double seam-like and push on methods. However, it is recognized that there are various other methods by which the closure 10 may be connected to the beverage container 12, such as a threaded connection.
- a resealable closure 10 for a beverage container 12 having a bottom 14 , a sidewall 16, and a top panel or lid 18 having a dispensing port 20, includes a sealing flap 22 and an external drive means 24 taking the form of a dust cover 26.
- dust cover 26 and “external drive means 24" are used interchangeably throughout this disclosure, although it should be appreciated that the external drive means does not also have to be capable of providing protection from debris.
- both the sealing flap 22 and the dust cover 26 slide in planes generally parallel to the lid 18.
- the present invention is not limited to sealing flaps and drive means that slide in planes generally parallel to the lid, but also includes sealing flaps and drive means that move in other planes as well.
- a sealing surface is provided between the sealing flap 22 and the perimeter of the dispensing port 20.
- the sealing surface may take the form of a separate sealing gasket 28.
- the sealing flap 22 may be made of a sufficiently resilient material to obviate the need for a sealing gasket 28.
- the sealing gasket 28 is preferably made of resilient materials, such as ethylene-vinyl acetate copolymer resins or acid-modified ethylene-acrylate. While it is recognized that the sealing gasket 28 can be attached either to the perimeter of the dispensing port on the underside 19 of the lid 18 or to the upper surface of the sealing flap 22, it is preferable, for manufacturing considerations, that the sealing gasket 28 be attached to the upper surface of the sealing flap 22.
- communication between the sealing flap 22 and the external drive means 24 is achieved in this second embodiment by a plurality of upwardly-directed projections 30 of the sealing flap 22, received in an aperture 31 of a socket 32 defined by projection-engaging members 33, preferably integral with, and extending downwardly from, the dust cover 24 through a hole 34 in the lid 18.
- Rib members 35 may also be provided on the underside of the dust cover 26 to slidably engage generally horizontal grooves 37 provided in the outermost sidewalls of the projections 30 to lock the sealing flap 22 and external drive means 24 into a constant vertical relationship with one another, at least while the external drive means 24 is causing movement of the sealing flap 22.
- venting means which preferably takes the form of a pressure equalization port, or vent hole 36.
- vent hole 36 may be provided in the sealing flap 22, or, alternatively, may take the form of a selectively unsealable hole (not shown) in the lid 18 that is covered by at least a portion of the dust cover 26.
- Some type of venting channel 38 is also preferably provided in a portion of the dust cover 26.
- the dust cover 26 When the dust cover 26 is in the initial closed position shown in FIGS. 9a and 9b, a bottom surface 39 of one of the projection-engaging members 33 initially tightly covers the vent hole 36. As the dust cover 24 is moved a small amount from its initial position to an intermediate position, shown in FIGS. 10a and 10b, the bottom surface 39 of the projection engaging member 33 uncovers the vent hole 36, quickly allowing the vent hole 36 to communicate with the venting channel 38, and allowing internal pressure of the beverage container 12 to equalize with atmospheric pressure. As a result, the friction between the sealing flap 22, the sealing gasket 28 and the underside 19 of the lid 18 is reduced to a level that allows movement of the sealing flap 22 with only a reasonable degree of effort applied by a user to . the dust cover 26. In a preferable resealable closure of the present invention, the dust cover 24 is moved approximately 15° from the initial position shown in FIG. 9a to the intermediate position shown in FIG. 10a.
- movement of the dust cover 26 does not immediately result in movement of the sealing flap 22. Instead, there is a delay, or dwell period, caused by a slack between initial movement of the dust cover 26 and initial movement of the sealing flap 22.
- This slack may be provided by making the differences between respective angles, such as d and ⁇ , between the surfaces of the elements that engage one another to initiate driving motion of the sealing flap 22, sufficient to allow venting to occur prior to motion of the sealing flap 22.
- this slack allows for approximately 15° of relative motion of the dust cover 26 to allow venting prior to movement of the sealing flap 22.
- the slack allows the vent hole 36 to be re-sealed prior to movement of the sealing flap 22 back toward its initial closed position underneath the dispensing port .
- the slack allows for a delay between initial movement of the dust cover 26 and initial movement of the sealing flap 22 not only before opening of the dispensing port 20, but also prior to closing of the dispensing port, is particularly advantageous because it allows re-sealing of the vent hole 36 to be a passive procedure, so the user will not forget to re-seal the vent after re-closing the dispensing port 20, undesirably allowing all the carbonation to be lost.
- the vent hole 36 is covered by the bottom surface 39 of one of the projection engaging members 30, thereby re-sealing the vent.
- the resealable closure of the present invention is of such a design that re-sealing of the vent hole 36 does not occur until after re-sealing of the dispensing port 20.
- Physical interference means are utilized in each embodiment of the present invention to initiate the seal between the sealing flap 22, the sealing gasket 28, and the perimeter of the dispensing port 20.
- a build up of internal pressure from gasses inside the beverage container 12 collecting in the head space beneath the lid causes a pressure differential that gradually results in an axial force that tends to enhance the seal between the sealing flap 22, the sealing gasket 28, and the perimeter of the dispensing port 20, in all embodiments wherein the sealing flap 22 is initially oriented beneath the perimeter of the dispensing port 20, i.e. under the lid 18.
- the source of the physical interference means shown in FIG.
- the 6 takes the form of one or more inwardly-directed annular ribs 44, offset a predetermined distance downwardly from the underside 19 of the lid 18, provided on an inner annular wall extending downwardly from the underside 19 of the lid 18.
- the predetermined distance for at least one of the ribs 44 is at least slightly less than the combined thickness of the sealing flap 22 and the sealing gasket
- the upper surfaces of the ribs 44 are progressively sloped, such that during rotation of the sealing flap 22, the distance between the ribs 44 and the underside 19 of the lid 18 decreases as the sealing flap 22 approaches a position directly beneath the dispensing port 20.
- the distal end 23 of the sealing flap 22 may also be tapered, as shown in FIG. 3, to facilitate a ramping interaction between the sealing flap 22 and the ribs 44.
- the present invention makes it unnecessary to overcome high friction between the sealing flap 22 and the ribs 44 throughout the duration of movement of the sealing flap 22 from the position shown in FIG. 10b to the position shown in FIG. lib.
- the tapered distal end 23 of the sealing flap 22 moves with increasing ease as the distance between the top of the ribs 44 and the underside 19 of the lid 18 increases.
- a user need only exert a reasonable amount of force on the tabs 40, 42 of the dust cover 26 to drive the sealing flap 22 to the fully open position shown in FIG. lib.
- Another advantage of the present invention is that, because the force a user needs to exert on the external drive means 24 is relatively small during the initial venting of the internal pressure of the beverage container 12, it is possible to provide a tamper evident feature that a user could easily break upon initial venting.
- the tamper evident feature may take the form of a raised pin
- the breakable membrane 66 is preferably an integral part of the dust cover 26. As the dust cover 26 is moved to the intermediate position to allow venting, the membrane 66 breaks, providing visible evidence that the dust cover 26 of the resealable closure 10 on the beverage container 12 has been manipulated.
- the raised pin also has a mushroomed top (not shown) that will prevent the dust cover from being raised out of rotational engagement with the pin without breaking the membrane .
- the pin 64 may also provide a stop to prevent over-rotation of the external drive means 24, so that the back end of the dust cover 26 is not rotated so far as to block the dispensing port 20.
- a third embodiment of the present invention utilizes a riveted bayonet-type fitting between the external drive means 24 and the sealing flap 22.
- a dwell period is provided between initial movement of the dust cover 26 and the sealing flap 22, achieved by means of providing a socket 32 that is larger than the horizontal bar 46 in the inverted T-shaped connector member 48 of the sealing flap 22.
- the stem or post 49 of the inverted T-shaped connector member 48 extends upwardly through che hole 34 provided in the lid 18, and through a post-receiving hole 50 provided in the dust cover 26.
- the top of the post 49 is then flattened (not shown) , to provide a riveted interconnection between the dust cover 26 and che sealing flap 22. Notwithstanding the riveted interconnection, the dust cover 26 can still move relative to the sealing flap 22 during the dwell period, i.e. until one of the walls of the socket 32 contacts one of the sides of the horizontal bar 46.
- a venting channel 38 selectively communicates with the vent hole 36 provided in the sealing flap 22 once the dust cover 26 reaches the intermediate position, i.e. the position shown in FIG. 10a, which vents the internal pressure of the beverage container.
- a vent hole 36 that is oriented along a side wall, such as in FIG. 16, with a molded-in venting channel 38 provided in the dust cover 26 that comes into communication with the vent hole 36 only upon rotation, is less susceptible to leakage.
- a vent hole gasket 47 is secured to the sealing flap 22, immediately surrounding the vent hole 36, to prevent leakage of gasses or liquids whenever the venting channel
- 15-16 is accomplished by moving the dust cover 26 in the opposite direction, which first brings the venting channel 38 out of communication with the vent hole 36, thereby re-closing the vent. Once the dust cover 26 reaches an intermediate position, such that the opposite side of the horizontal bar 46 comes into contact with the another wall of the socket 32, further rotational movement of the dust cover 26 causes the sealing flap 22 to return to its initial position, thereby closing the dispensing port 20.
- the dust cover 26 and the sealing flap 22 are axially locked to - one another due to the riveting of the post 49.
- buttons 41 may be provided on the underside of the dust cover 26, which ride in curved, sloped raceways 43 in the top of the sealing flap 22 as dust cover 26 moves relative to the sealing flap 22.
- the third embodiment of the present invention shown in FIG. 14 also addresses concerns regarding contamination of exposed portions of the lid 18.
- One reason many people prefer bottles to cans is that because individual beverage containers undergo substantial handling between the time of packaging and the time of consumption, there is great opportunity for debris to collect on cans, particularly on the surface of the lid 18 between the dispensing port 20 and the sidewall 16, where the user's mouth touches the beverage container 12.
- the cap In bottles, however, the cap generally covers the threaded region where the user's mouth would touch, ⁇ except when the user is drinking.
- the dust cover 26 of the resealable closure shown in FIG. 14 includes a lip 51, having an inner portion 52 extending up the inner sidewall of the lid 18, an annular top portion 54, and an outer portion 56 that extends down the rim of the lid 18.
- This lip 51 effectively extends the dust cover 26 over the region of the lid 18 that is typically exposed in conventional cans.
- Annular top portion 54 is preferably provided with a tapered edge, and the rim of the lid 18 is provided with a complementary leading ramp, to facilitate slight lifting of the inner portion 52 of the lip 51, which enables rotating motion of the dust cover
- a stop member 58 in the form of a generally vertical tab may also be provided on the lid 18 in order to define a limit to the travel of the dust cover 26.
- the stop member 58 in FIG. 14 is shown to the right of the dispensing port 20, so it will be appreciated that the dust cover 26 is moved in the counter-clockwise direction to open the resealable closure 10, whereas the dust cover 26 in the second embodiment shown in FIGS. 6-8 is opened by moving in the clockwise direction.
- the dust cover 26 is extended to cover a broader area of the lid 18, in order to provide even additional sterility to the region of the beverage container 12 touched by a user's mouth.
- the outer portion 56 of the dust cover 26 may be provided with a plurality of gripping ribs 60 to facilitate handling and rotation of the dust cover.
- the communication between the dust cover 26 and the sealing flap 22 is such that there is a dwell period or slack, during which a vent hole 36 in the sealing flap 22 is exposed by movement of the dust cover 26 to allow venting of the internal pressure of the beverage container prior to opening of the dispensing port 20.
- the interconnection of the dust cover 26 and the sealing flap 22 in this fourth embodiment can be similar to the interconnections shown in FIG. 14 or in FIGS. 15 and 16 for the third embodiment.
- the lid 18 may advantageously be provided with a dispensing spout 62 to facilitate drinking the beverage through the dispensing port 20, and to facilitate drainage back into the beverage container 12 through the dispensing port 20 of excess beverage that may collect on the lid 18.
- Such a dispensing spout may also be provided in a resealable closure of the third embodiment, as shown in FIG. 14. It will be appreciated that in both the third and fourth embodiments, the manner of providing the initial mechanical interference necessary to initiate the seal between the sealing flap 22, the sealing gasket 28, and the perimeter of the dispensing port 20 may be similar to the ribs 44 shown in FIG. 6, or may take other forms as explained in greater detail below. As shown in FIGS.
- the means of creating physical interference to initiate a seal between the sealing flap 22, the sealing gasket 28 and the perimeter of the dispensing port 20 may instead take the form of an annular shelf 45 extending the entire circumference of the beverage container 12 , formed either as an integral part of the resealable closure, as shown in FIG. 18, or formed in the sidewall 16 of a can.
- an annular shelf 45 extending the entire circumference of the beverage container 12 , formed either as an integral part of the resealable closure, as shown in FIG. 18, or formed in the sidewall 16 of a can.
- the distal end 23 of the sealing flap 22 is preferably tapered, as best seen in
- FIG. 20 so that the contact between the sealing flap 22 and the underside 19 of the lid 18 gradually increases as - the sealing flap 22 approaches a position directly beneath the dispensing port 20.
- the sealing flap 22 in order to accomplish the eccentric movement of the sealing flap 22 in a way that results in a flush, synchronized contact of the sealing flap 22 and the portion of the shelf 45 underneath the dispensing port, the sealing flap 22 must have an asymmetrical perimeter. It will also be recognized by those of ordinary skill in the art that the physical interference means which biases the sealing flap 22 in a direction toward the underside 19 of the lid 18, and thereby initiates the seal between the sealing flap 22, the gasket 23, and the perimeter of the dispensing port 20, need not be located along the perimeter of the lid 18. Instead, it could take the form, for example, of a radially-oriented shelf
- a particular advantage of the present invention is that this seal is enhanced by the differential between the internal pressure, resulting from, e.g., carbonated beverages, and atmospheric pressure, in those embodiments where the sealing flap 22 is initially oriented underneath the perimeter of the dispensing port 20.
- a sixth embodiment of the resealable closure of the present invention is shown in which both the dust cover 26 and the sealing flap 22 flip outside of planes that are parallel to the lid 18.
- this embodiment also includes an initial slack during which venting takes place as a result of movement of the dust cover 26 prior to initial movement of the sealing flap 22.
- the external drive means 24 pivots about an axis just below the underside 19 of the lid 18.
- the pivot axis at a rear end of the external drive means 24 sits in a well 68 provided in the lid 18.
- the well 68 includes a pair of side walls 70, 72, a front wall 74 a rear wall 76, and a floor 78.
- the venting of the resealable closure 10 is achieved with an axle 80 at the rear end of the dust cover 26, inside the well 68.
- the axle 80 includes a venting channel 38, which leads to the outside of the axle 80, thereby venting any gases in the channel 38.
- the venting channel 38 selectively rotatably engages a vent hole 36 provided in a rotatable drive gear shaft 82.
- vent hole 36 is always in communication with a hollow central gas passageway 84 within the drive gear shaft 82, the internal pressure equalizes with the surrounding atmospheric pressure as soon as the venting channel 38 communicates with the vent hole 36. This takes place during the initial dwell period, i.e. before the axle 80 actuates the drive gear shaft 82.
- vent hole gasket 47 in the embodiment shown in FIG. 16 is used to seal a vent hole 36 when not in communication with a venting channel 38
- a gasket material (not shown) suitable to provide a gas tight seal for the vent hole 36 in the drive gear shaft
- an annular gasket 86 is preferably provided at the intersection of the drive gear shaft 82 and the side walls 70, 72.
- a radial surface in the interior of the axle 80 contacts a radial extension of the drive gear shaft 82, and further flipping movement of the external drive means 24 away from the plane of the lid 18 causes the axle 80 to rotate the drive gear shaft 82 in the same direction.
- the drive gear shaft 82 is provided with at least one drive gear 88 provided outside one or both side walls 70, 72.
- the drive gear 88 has been omitted from FIG. 24 for clarity, but can be seen in FIGS. 22, 23 and 25.
- the drive gear 88 includes a multiplicity of gear teeth that engage complementary teeth in a seal flap gear 90, at least one of which is provided on a separate seal flap gear shaft 92 extending from a projection 94 of the well 68 that extends forwardly the front wall 74 of the well 68.
- the projection 94 of the well 86 is narrower than the distance between the side walls 70, 72, which allows the seal flap gear shaft 92 to be integral with a rear end of the seal flap 22, in the same manner that the axle 80 is integral with the rear end of the external drive means 24. It is recognized that this slack between the radial surface of the interior of the axle 80 and radial extension of the drive gear shaft 82, which allows venting to occur prior to movement of the sealing flap
- Movement of the drive gear shaft 82 results in clockwise rotation of the drive gear 88, thereby causing counter-clockwise rotation of the seal flap gear 90 and the seal flap gear shaft 92, resulting in the seal flap 22 flipping down and away from the dispensing port 20. Because the dust cover 26 covers the dispensing port 20 until the beverage container 12 reaches the user, the fact that the sealing flap 22 is moving down and into the beverage itself is of little concern to the user, inasmuch as there is only a small chance that debris can contaminate any surface of the sealing flap .22.
- sealing flap 22 and sealing gasket 28 it is desirable to initiate the sealing force to seal the sealing flap 22 and sealing gasket 28 to the perimeter of the dispensing port 20 on the underside 19 of the lid 18.
- Such an initial sealing force was provided in previous embodiments, in which the sealing flap 22 rotated in a direction generally parallel to the lid 18, by translating angular motion of the sealing flap 22 into a sealing force generally perpendicular to the perimeter of the dispensing port 20.
- the direction of motion of the sealing flap is already generally perpendicular to the perimeter of the dispensing port 20.
- initial physical interference means to translate angular motion of the sealing flap 22 into a force in a direction generally perpendicular to the perimeter of the dispensing port.
- the seal between the sealing flap 22, the sealing gasket 28, and the perimeter of the dispensing port 20 is enhanced by virtue of the forces resulting from the pressure differential biasing the sealing flap 22 toward the perimeter of the dispensing port 20.
- the sealing force between the sealing flap 22, the sealing gasket 28, and the perimeter of the dispensing port 20 is advantageously sufficiently enhanced to make it unnecessary to continue to apply a compressive force to the external drive means. It will be appreciated that forms of engagement other than interlocking circular gears could be used to convert the rotation of the dust cover 26 into the desired flipping of the sealing flap 22.
- a seventh embodiment of the resealable closure 10 of the present invention involves applying the same principles of the invention to a resealable closure 10 in which the external drive means 24 moves in a plane generally parallel to the lid 18, and selectively actuates movement of the sealing flap 22 in a direction outside of a plane generally parallel to the lid 18.
- the dust cover 24 in this embodiment may be of a style that extends on either side of the central axis of the beverage container,- such as the dust cover 26 shown in FIGS. 14-15, but for clarity, FIG. 26 shows a dust cover 26 that only has a single tab 40 for a user to grip to actuate the dust cover 26.
- an initial dwell period is provided during movement of the dust cover 26 prior to actuation of the sealing flap 22 in order to unseal a vent hole 36.
- a "bow-tie" connector 96 (named for its shape) projects downwardly from the dust cover 26, and is preferably an integral extension thereof.
- the bow-tie connector 96 is received in a socket 32 in a drive gear shaft 82.
- the walls of the socket 32 are spaced so as to provide sufficient slack or clearance for the male portion of the bow-tie connector 96 to not only be received in the socket 32, but also to rotate a short distance, preferably about 15°, in order to unseal the vent hole 36 prior to taking up this slack and moving the drive gear shaft 82.
- a beveled drive gear 88 is provided at the bottom end of the drive gear shaft 82, and is provided with an annular gasket 86. At least a portion of the drive gear shaft 82 extends through the hole 34 in the lid 18, so that the annular gasket can be seated against the underside 19 of the lid 18, or at least against the bottom of a collar (not shown) extending downwardly from the hole 34 in the lid 18, to prevent leakage of gasses and liquids. Once the vent hole 36 is unsealed, the bow-tie connector 96 comes into intimate contact with the walls of the socket 32. Continued rotating motion of the external drive means 24 (in the direction indicated by the arrows in FIG.
- the dummy gear 98 is provided primarily for symmetry and support, rather than function.
- the sealing flap gear shaft 92 is also received in (or, alternatively, may be an integral part of) the sealing flap 22.
- the initial physical interference necessary to initiate the sealing force to seal the sealing flap 22 and sealing gasket 28 to the perimeter of the dispensing port 20 on the underside 19 of the lid 18 can be achieved by means of a pre-load of the seal flap gear 90 by the drive gear 88.
- an eighth embodiment applies the principles of the present invention to a resealable closure 10 in which it is the dust cover 26 that flips outside a plane generally parallel to the lid 18, which, subsequent to pressure equalization by venting of the internal pressure, causes the sealing flap 22 to move by rotation in a direction generally parallel to the lid 18.
- the slack during which venting occurs prior to movement of the sealing flap 22 can achieved primarily in the same way as discussed above with regard to the sixth and seventh embodiments, so a detailed explanation thereof is omitted.
- a worm drive gear 88 provided outside (i.e., on the beverage side) of side wall 70 of a well 68 in the lid 18, rotates, causing rotational movement of a seal flap gear 90 by virtue of a multiplicity of teeth on the seal flap gear 90 riding along the worm gear 88.
- the seal flap gear 90 is shown in FIG. 28 to be integral with the seal flap 22, and both rotate about a seal flap gear shaft extending downwardly from the underside 19 of the lid 18 to move the seal flap 22 in the direction of the arrow shown in the drawing figure immediately adjacent the preferably tapered distal end 23 of the sealing flap
- the initial mechanical interference can be accomplished by use of the annular shelf 45 shown in FIGS. 18 and 21, if the sealing flap travels along a different radius of curvature than the radius of curvature of the sidewall 16 of the beverage container 12.
- FIGS. 29 and 30 show -a ninth embodiment, wherein the external drive means 24 starts in a position away from the dispensing port 20, such that initially, only the sealing flap 22 prevents debris from entering the beverage container. It is understood that this embodiment may be less desirable, inasmuch as a portion of the sealing flap 22 that is exposed during shipment of the beverage container 12 flips down into the beverage.
- FIGS. 31 and 32 show a tenth embodiment, in ⁇ . ⁇ which rotation of the external drive means 24 in a plane generally parallel to the plane of the lid 18, after an initial dwell period to accomplish venting in a manner described above, rotates a drive gear 88, which causes axial movement of the sealing flap 22.
- the sealing flap 22 is preferably made of a' flexible material, and is provided with internal threads 100 so as to axially ride along the drive gear 88 as the drive gear rotates.
- One or more columns 102, 104 may be provided along the interior of the sidewall 16 of the beverage container 12, so as to constrain movement of the sealing flap 22 in the axial direction.
- the initial mechanical interference can be accomplished by applying a pre-load, so that as the external drive means 24 returns to a position immediately over the dispensing port 20, the sealing flap 22 and sealing gasket 28 are sealed to the perimeter of the dispensing port 20 on the underside 19 of the lid 18.
