Abstract
Disclosed is a device for creating a seal which includes an upper seal member, a lower seal member, and a slider, wherein mating surfaces of the upper and lower seal members interlock. A lifting rib on the slider cooperates with a lifting wing on the upper seal member and a closure bar cooperates with a closure bar groove of the lower seal member. By moving the slider in one direction, the lifting rib lifts the upper seal member from its interlocking relationship with the lower seal member. Moving the slider in the opposite direction causes the upper and lower seal members to interlock. Also disclosed is a seal device which includes upper and lower seal members and a cooperating slider and plug. Each of the slider and plug cooperate with first and second mating surfaces of the upper and lower seal members. In addition, the slider and plug have an exterior tongue and groove portion which cooperate to interlock the slider and the plug.
Description




FIELD OF THE INVENTION




The present invention relates to a device that is capable of creating a seal between fabrics and other materials.




BACKGROUND OF THE INVENTION




Fastening devices typically include two flexible elongated components having teeth which are forced to interlock and separate by moving a slide along the components. Although such fastening devices have long been used to close and open various articles, such as clothing and bags, such devices suffer from the allowance of liquids and gases within the fastener, and are therefore not useful for conditions in which a wind-proof, gas-tight and/or waterproof article is desirable.




Fluid-tight fasteners are available, but such fasteners are typically not fluid-tight at the ends of the fastener. Furthermore, other devices have sealing members that are aligned adjacent each other as opposed to extending away from each other. Still other devices are expensive, heavy, and/or require the use of a covering material over the fastener to establish a wind and/or watertight closure.




SUMMARY OF THE INVENTION




The unique feature of the present invention is its ability to provide a seal to an object that has two opposing surfaces of material, while always maintaining the slider portion of the device to the exterior of the enclosure.




In a first embodiment, the seal device is comprised of three main components (1) a upper seal member, (2) a lower seal member, and (3) a slider. The slider includes at least one lifting rib and a closure bar. In use, the slider is moved back and forth across the length of the seal to interlock the upper seal member to the lower seal member, thereby forming a seal. More particularly, the slider body includes a confining portion that presses the upper seal member into the lower seal member when the slider is moved in a closing direction. To open the seal, the lifting rib within the slider pulls the upper seal member away from the lower seal member that is anchored to the bottom of the slider by the closure bar.




In a modification of the first embodiment, a slider is provided that only contains one lifting rib within an opening portion of the slider. The closure portion of the slider includes a closure bar that anchors the lower seal member, and allows the slider body to press the upper seal member into the lower seal member to close the seal. The closure portion may include a canted portion that tilts, thereby creating some slight rotation of the upper seal member as it enters the lower seal member, thereby improving the seal quality. The opening portion of this modified embodiment preferably includes one lifting rib that separates the upper seal member from the lower seal member by lifting the upper seal member under its lifting wing. Separation from the lower seal member occurs because the lower seal member is anchored to the bottom of the slider by the closure bar that preferably extends the length of the slider. When used with one lifting rib, the opening portion creating some slight rotation of the upper seal member as it exits the lower seal member, thereby improving the ease of slider movement and the longevity of the seal quality.




In a second embodiment, a waterproof sealing device is comprised of four main components (1) a upper seal member, (2) a lower seal member, (3) a slider, and (4) a plug. The upper seal member of this embodiment does not require a lifting wing. Furthermore, the lower seal member does not require a closure bar groove. The slider of this embodiment has interior structure that mates and cooperates with the seal surfaces of the upper seal member and the lower seal member. Furthermore, the shape of the interior structure of the slider is analogous to a funnel. As the slider is passed along the length of the seal, the slider confines the seal at its closing end to from the seal. That is, the upper seal member and the lower seal member are funneled together. When used in an opening direction, the opposite occurs, and the interior structure of the seal separates the upper seal member from the lower seal member.




The second embodiment creates a waterproof seal at the end-most extent of the seal using the plug. The plug is permanently affixed to the end of the seal. Furthermore, the plug contains interior structure that mates with mating surfaces of the upper seal member and the lower seal member. In addition, the structure of the plug mates with the slider when the slider is moved into its closing position with the slider. Therefore, the mating surfaces of the upper seal member and the lower seal member create a seal around the interior structure of both the slider and the plug when the slider is moved into its closing position with the plug.

While the following disclosure describes the invention in connection with those embodiments presented, one should understand that the invention is not strictly limited to these embodiments. Furthermore, one should understand that the drawings are not necessarily to scale, and that 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.




DETAILED DESCRIPTION OF THE INVENTION




One embodiment of the present invention is a device for creating a seal. The device includes an upper seal member, a lower seal member and a slider. The upper seal member has a first mating surface and a lifting wing. The lower seal member has a second mating surface and a closure bar groove. The first and second mating surfaces interlock to form a seal. The slider includes a lifting rib that slideably cooperates with the lifting wing of the upper seal member, and a closure bar that slideably cooperates with the closure bar groove of the lower seal member. The slider also includes a body having a closing end at which the lifting rib is in closing proximity with the closure bar and an opening end wherein the lifting rib is in opening proximity with the closure bar. When the slider is moved in a direction causing the upper seal member and the lower seal member to pass within the slider from the opening end to the closing end, the slider confines the first mating surface into contact with the second mating surface thereby creating a seal.




Referring initially to

FIG. 1

, a perspective view of the sealing device


10


is shown. The sealing device


10


includes an upper seal member


12


, a lower seal member


14


, and a slider


16


. Sealing device


10


creates a seal


17


along the entire length of upper seal member


12


and lower seal member


14


. When device


10


is unsealed, an opening


18


exists between upper seal member


12


and lower seal member


14


, thereby providing access to the space to the interior of the seal


17


.




In use, a seal


17


is formed by sliding slider


16


down the length of seal


17


, which causes the slider


16


to interlock the mating surface


20


of upper seal member


12


with the mating surface


22


of lower seal member


14


. As such, the present invention bears similarity to a zipper, whereby the user of the device zips the device


10


closed to form a seal, and unzips device


10


to gain access to the interior of the seal


17


.




Referring now to

FIG. 2

, a perspective view of upper seal member


12


and lower seal member


14


is shown without the slider


16


present.

FIG. 2

clearly illustrates that, if desired, upper seal member


12


may be reversed relative to lower seal member


14


. That is,

FIG. 1

illustrates that upper seal member


12


extends to the upper right of the page, while the lower seal member


14


extends to the lower left of the page. Conversely,

FIG. 2

illustrates that upper seal member


12


may extend in a reverse direction, that is, to the lower right of the page, while the lower seal member


14


extends to the upper right of the page. Therefore, sealing device


10


can be configured to provide access from either direction to the interior of the article to which it is attached. Of course, if seal


17


is sufficiently long, when unsealed upper seal member


12


may be moved away from lower seal member


14


to provide extensive access from any direction to the interior of the article to which device


10


is attached.




Referring now to

FIG. 3

, a cross-sectional view of interlocked upper seal member


12


and lower seal member


14


is depicted. This figure provides a detail view of the structure of the two interlocking members. The upper seal member


12


preferably includes at least one lifting wing


24


, and may include two or more lifting wings


24


as depicted in FIG.


3


. More specifically, in a preferred embodiment, a portion of upper seal member


12


includes a lifting wing


24


that juts out from the main profile portion


25


of the upper seal member


12


. Lifting wing


24


thus creates a lifting wing groove


26


directly thereunder that serves as a receiving location for a lifting rib


46


of slider


16


, discussed in detail below. Lifting wing


24


may be a variety of shapes, as may lifting groove


26


. If the lifting wing


24


is removed, as depicted starting at location


28


in

FIGS. 1 and 2

, the absence of the lifting wings


24


prevents the lifting rib


46


of slider


16


from placing a separation force on the upper seal member


12


, and thereby prevents slider


16


from separating seal


17


at the beginning of location


28


of the seal


17


. Accordingly, an end portion


30


of seal


17


preferably contains a section that is slightly shorter than the length of the slider


16


, whereby the lifting wings


24


are absent from the upper seal member


12


. In use, when slider


16


is pulled along to the end portion


30


of the seal


17


, the lifting rib


46


of the slider


16


disengages from the lifting wing groove


26


, thus preventing separation at the front end of the slider


16


. This disengagement allows the seal at the front of the slider


16


to remain sealed, thereby providing a seal along the entire length of seal


17


, including the end portion


30


where slider


16


is positioned for closure of seal


17


.




Still referring to

FIG. 3

, a closure bar groove


32


is provided for stabilizing lower seal member


14


during operation of the slider


16


. In a preferred embodiment, lower seal member


14


includes a closure bar groove


32


. Closure bar groove


32


is design to receivingly accept a closure bar


48


of slider


16


, shown, e.g., in FIG.


6


. Closure bar groove


32


may be of different lengths and shapes, as will be discussed below. Furthermore, closure bar groove


32


may include an end shape


34


that corresponds to an end shape


51


of the terminus


52


of the closure bar


48


, as discussed below.




Referring now to

FIGS. 1-3

, mating surface


20


of upper sealing member


12


and mating surface


22


of lower sealing member


14


provide the structure for creating a functioning seal


17


. More particularly, upper seal member


12


includes a mating surface


20


that has a shape that mates with mating surface


22


of lower seal member


14


, thereby creating a seal


17


. The shape of the mating surfaces


20


and


22


may vary, as discussed below. In use, mating surface


20


is forced into interlocking position with opposing mating surface


22


, thus creating seal


17


.




Referring to

FIGS. 1 and 3

, it is an aspect of the present invention to utilize materials of sufficient dimension and material type such that seal


17


may be incorporated into a variety of different objects, such as wet suits, waders, rain gear, marine apparel, and boots, to name but a few. Accordingly, upper seal member


12


preferably includes a sufficient width W


1


of runout material such that it may be permanently attached to an object to form one side of the seal on the object. Similarly, the lower seal member


14


also includes a sufficient width W


2


of runout material such that it too may be permanently attached to an object to form a second side of the seal for the object. Upper seal member


12


and lower seal member


14


are made of resilient material that is capable of interlocking to form a seal. The upper and lower seal members


12


,


14


can be made of the same or different resilient materials. Such materials may include, but are not limited to rubber or plastic, such as poly-vinyl chloride (PVC) or linear low density polyethylene (LLDPE). Depending upon the material used, the upper seal member


12


and lower seal member


14


may be glued, heat welded, or otherwise bonded to adjacent material of the enclosure object O, as shown in phantom lines in FIG.


1


. Alternatively, the seal


17


of the present invention may be formed as an integral part of the object during manufacture of the object itself. In one aspect of the invention, the upper and lower seal members are attached to adjacent material surfaces as part of a product, such as, for example, a jacket front. Thus, the material surfaces would be the left and right front sides of the jacket, which substantially define a first plane. The interlocked first and second mating surfaces of the upper and lower seal members also substantially define a plane, such as is illustrated in FIG.


6


. In this aspect of the invention, these two planes are substantially parallel.




It is an aspect of the present invention that a variety of materials may be used to construct a single device


10


. The slider


16


is preferably made of a relatively hard material, such as, without limitation, a hard plastic, rubber, ceramic, metal, metal alloy, or a combination thereof. Mating surfaces


20


and


22


may, if desired, incorporate a multitude of materials. For example, individual male shapes


60


and female shapes


62


may be formed of one material, such as soft rubber, while the remaining portions of the upper seal member


12


and lower seal member


14


may be manufactured of a somewhat harder material that still behaves in a resilient manner. Furthermore, upper seal member


12


and lower seal member


14


, including mating surfaces


20


and


22


may incorporate metallic or hard plastic inserts, while hook and loop materials such as velcro may be incorporated into the device


10


as well. In addition, a variety of other materials, such as, without limitation, gel, silicone, polytetrafluoroethylene (PTFE) fibers, metal or coil zipper sections, lubricants, and/or sealants may all be used in or on one or more of the components of the inventions disclosed herein.




The device for creating a seal of the present invention has a wide variety of uses and advantages. In general, the device can be used for outdoor clothing and apparel, outdoor equipment and cases, marine apparel and equipment, and even for everyday apparel. The device is particularly useful for products that are required to be fully watertight. Such products include, without limitation, hazardous material suits, fire suits, dry suits, dry bags, bivy sacks, waders, space suits, tents, shipping packages, household storage bags, map cases, chart cases, kayak skirts, backpack covers, computer cases, electronic device cases, watercraft containers, inflatable cases (for cameras, etc.), flotation bags, flotation devices, waterproof pockets, fishing vest pockets, smell-proof pockets (for bears, etc.), and wetsuits. The device of the present invention is also particularly useful for products requiring or benefitting from being wind proof. Such products include, without limitation, jackets, sleeping bags, rain gear, boots, kayak jackets, wind breakers, wind proof fleeces, and tents. In addition to the advantages of being waterproof and wind proof, the device of the present invention has a number of other advantages, including, without limitation, being: airtight, watertight, gas tight, wind proof, quiet, less likely to get caught or jammed, lightweight, nonmetal (i.e., light, cheap and not cold), fully recyclable, smooth to operate, inexpensive and easy to produce. This device also eliminates the need for zipper-covering flaps and can be used in essentially any zipper function, thereby allowing hundreds of new products to be made using the device. Specifically, such new products can include the following: zip-down waders, zip-down dry bags, zip-down bivy sacks, easy access kayak skirts, fully waterproof rope bags, fully waterproof pockets, watertight/airtight shipping packages, easy access dry suits, everyday camera bags for underwater photos or films, fully waterproof and fully functional backpacks or fanny packs, zip-down rain pants and zip-in-half rain tarps.




Referring now to

FIG. 4

, a side elevation view of a slider


16


is depicted engaged in upper seal member


12


and lower seal member


14


. The slider


16


includes an opening end


36


and a closing end


38


. When pulled in either direction along the seal profile


17


, the last end of the slider


16


to pass the profile renders the seal either opened or closed. More specifically, opening end


36


serves to separate the upper seal member


12


from the lower seal member


14


. Therefore, as slider


16


is pulled along the seal


17


, it will open the seal


17


if pulled such that closing end


38


leads opening end


38


. Conversely, closing end


38


of slider


16


confines and presses the upper seal member


12


into interlocking union with lower seal member


14


. Therefore, as slider


16


is pulled along the seal


17


, it will close the seal


17


if pulled such that opening end


36


leads closing end


38


. In this mechanism of opening and closing, the seal is opened by force being applied by the lifting rib to the lifting wing to pull the upper seal member from the lower seal member. This mechanism is different from sealing devices where a force is applied directly to a mating or contacting surface that makes a seal.




Still referring to

FIG. 4

, a pull tab


40


is preferably mounted along the top of slider


16


using a pin


42


to interconnect pull tab


40


within a pull tab sliding track


44


. Pull tab


40


slides back and forth in the pull tab sliding track


44


allowing for a more effective pulling angle for the slider


16


, thus allowing for a smoother and easier effort to manipulate slider


16


.




Referring now to

FIG. 5

, a lifting rib


46


can be seen at the opening end


36


of slider


16


. Lifting rib


46


provides a structure for applying a separating force to the upper seal member


12


relative to the lower seal member


14


.




Referring now to

FIG. 6

, an elevation view of the closing end


38


of the slider


16


taken along line

FIG. 5

is provided.

FIG. 6

depicts the disposition of the upper seal member


12


and lower seal member


14


at the closing end


38


of slider


16


. At the closing end


38


, closure bar


48


fits within closure bar groove


32


of lower seal member


14


, and serves to confine the mating surface


22


of lower seal member


14


within the body


50


of slider


16


. The body


50


of slider


16


is confined at the closing end


38


of slider


16


such that the mating surface


20


of upper seal member


12


is forced to interlock with mating surface


22


of lower seal member


14


.





FIG. 7

provides a perspective view of slider


16


looking at the opening end


36


of the slider


16


. In contrast,

FIG. 8

provides a perspective view of slider


16


looking at the closing end


38


of the slider


16


. Lifting ribs


46


located on both lateral sides of slider


16


are shown. It should be noted that lifting ribs


46


can extend along the entire lateral side of slider


16


or along only a portion thereof, such as along the front half of the slider


16


at the opening end


36


. The distance between the lifting ribs


46


and the closure bar


48


at the opening end


36


is significantly greater than at the closing end


38


of slider


16


. More specifically, separation distance S


1


depicted in

FIG. 7

is greater than separation distance S


2


depicted in FIG.


8


. Separation distance S


1


is sufficiently large to separate the mating surface


20


of upper seal member


12


from the mating surface


22


of lower seal member


14


. Referring back to

FIG. 5

, the separation of upper seal member


12


from lower seal member


14


is clearly illustrated at the opening end


36


of slider


16


. In contrast, referring back to

FIG. 6

, the geometry of the closing end


38


of slider


16


is such that upper seal member


12


is in interlocking position with the lower seal member


14


. Thus, the distance between the opening end


36


and closing end


38


of slider


16


is a transition zone, whereby upper seal member


12


is releasably separated from lower seal member


14


at opening end


36


, or where upper seal member


12


is releasably interlocked with lower seal member


14


at closing end


38


.




The component parts of the present invention may incorporate a myriad of different configurations. Referring now to

, such that it rises to the same elevation as the corresponding surface of upper seal member


12


. This modification allows for a relatively low profile zipper-like configuration in the vicinity of the seal


17


.




Referring now to

FIG. 9



f


, a variety of end shapes


51


may be used at the terminus


52


of the closure bar


48


. Alternately, a simple shape may be used at any point (not shown) along the length of closure bar


48


.

FIG. 9



f


illustrates that a truncated half circle resembling an arrow may be used as the end shape


51


at terminus


52


of the closure bar


48


. Accordingly, although not illustrated, it is to be understood that the terminus


52


may have an end shape


51


taking many forms, including, but not limited to circles, triangles, rectangles, arrow heads, barbs, and polyhedral shapes. Furthermore, as shown in

FIG. 9



g


, the terminus


52


of closure bar


48


may be without any type of additional shape at all. This modification is particularly applicable in the case where the closure bar


48


is longer than a simple prong shape, thus providing confinement capability and support to the mating areas of the profile simply by virtue of its length under the mating area itself.





FIG. 9



h


depicts a modified slider


16


shape that does not wrap around the top surface of the upper seal member


12


. Here, the modified slider


16


of

FIG. 9



h


has a lifting rib


46


that projects into the top surface


47


of the mating profile of the upper seal member


12


. In addition, a second lifting rib


46


in located along the side of slider


16


. Advantageously, the top-most lifting rib


46


of this modified slider


16


includes a shape


49


to anchor the lifting rib


46


within the lifting rib groove


26


. A variety of shapes


49


for the lifting rib


46


and corresponding lifting rib groove


26


may be used to provide a mechanism for anchoring the lifting rib


46


within the top surface


47


upper seal member


12


, such that lifting rib


46


pulls the upper seal member


12


out of the lower seal member


14


at the opening end


36


of slider


16


.




Referring now to

FIG. 9



i


, a slider


16


having a single lifting rib


46


is provided. More specifically, the modified slider


16


as presented in

FIG. 9



i


utilizes a single lifting rib


46


that projects into the top surface


47


of the mating profile


20


of upper seal member


12


. As with the slider illustrated in

FIG. 9



h


, the slider


16


of

FIG. 9



i


uses a shape


49


at the end of the single lifting rib


46


to provide a structure for pulling the upper seal member


12


out of the lower seal member


14


when the profile passes through the opening end


36


of slider


16


.





FIG. 9



j


illustrates that a combination of the above described features may be utilized to form a slider/seal combination. Here,

FIG. 9



j


illustrates a slider


16


having a relatively long closure bar


48


, and also having two lifting ribs


46


, the first lifting rib


46


located on the side of the slider


16


, and the second lifting rib


46


is located along the top surface


47


of the main profile portion


25


of the upper seal member


12


. Furthermore, lower seal member


14


is wrapped around the side of slider


16


and rises to an elevation such that the top lateral surface


53


of lower seal member


14


is at about the same elevation as the top lateral surface


55


of upper seal member


12


.




Referring now to

FIG. 9



k


, a slider


16


having a cylindrical shape is shown. The cylindrical shaped slider


16


includes a closure bar


48


and a body


50


that wraps around the exterior of the main profile portion


25


of upper seal member


12


, where it terminates at a lifting rib


46


. Accordingly, the shape of the slider


16


may vary considerably and yet provide the function of opening and closing seal


17


.




Referring now to

FIG. 9



l


, a stiffener insert


54


is provided for strengthening the profile system of the present invention. More specifically, a plurality of stiffener inserts


54


may be spaced along portions of the seal


17


of the present invention, by including inserts


54


within lower seal member


14


. The inserts


54


provide a stronger seal structure, while at the same time permitting the seal to behave in a relatively flexible manner as a result of the spaced nature of placement. Spaced placement of inserts is disclosed in U.S. Pat. No. 5,991,980, the contents of which is incorporated herein by reference, in its entirety.




Referring again to

FIG. 9



l


, the insert


54


is shown bending to follow the general shape of lower seal member


14


, where lower seal member


14


includes a closure bar groove


32


. Stiffener inserts


54


may be used in any profile shapes disclosed herein. For example,

FIG. 9



m


illustrates a slider


16


having a closure bar


48


that is essentially prong shaped. Here, insert


54


follows the general contour of the lower seal member


14


, which rises in elevation to match the elevation of the upper seal member


12


. Similarly,

FIG. 9



n


illustrates the use of an insert


54


with slider


16


that has a semi-circle end shape


51


at the terminus


52


of the closure bar


48


.




Referring now to

FIG. 9



o


, in a separate aspect of the present invention, a seal member rib


56


may be used to provide additional stability to the seal profile. More particularly, seal member rib


56


is a structure that protrudes from lower seal member


14


to buttress the interlocked main profile portions


25


of upper seal member


12


and lower seal member


14


. The seal member rib


56


serves to assist in preventing the main profile portions


25


of interlocked upper seal member


12


and lower seal member


14


from shifting or rotating toward lower seal member


14


. Preferably, the rib end


58


of seal member rib


56


protrudes into lifting rib groove


26


, thereby adding additional stability. Seal member rib


56


may be formed in a variety of shapes and may include a stiffener insert


54


. Furthermore, seal rib member


56


may be configured to fit over (not shown) at least a portion of the profile section of upper seal member


12


. In use, closure bar


48


of slider


16


passes through closure bar groove


32


, deflecting seal member rib


56


outward away from the seal profile area until the upper seal member


12


is interlocked with the lower seal member


14


. After the slider


16


passes a section of the profile, seal member rib


56


returns to a position that buttresses the seal profile, as shown in

FIG. 9



o.






As illustrated in

FIG. 3

, the seal is formed by forcing mating surface


20


of upper seal member


12


in interlocking contact with the mating surface


22


of lower seal member


14


. Mating surfaces


20


and


22


, therefore, are mating shapes that allow the two surfaces to interlock, thereby forming a seal. Each mating surface is formed of at least one, or alternatively, a plurality of male shapes


60


and female shapes


62


that mate with each other. Referring now to

FIG. 10

, various individual male mating shapes


60


are presented. As

FIG. 10

illustrates, a wide range of male shapes


60


are possible.

FIG. 11

illustrates a matching set of female shapes


62


that may be paired with the male shapes


60


to form interlocking pairs


64


of male shapes


60


and female shapes


62


, as shown in FIG.


12


. When forming a mating surfaces


20


,


22


, a different assortment of male shapes


60


and females shapes


62


may be used to form a plurality of shapes in one mating surface


20


,


22


, so long as each male shape


60


matches with a corresponding female shape


62


. Thus, a wide variety of combinations of male shapes


60


and female shapes


62


may be used to create unique matched sets of mating surfaces


20


and


22


. Furthermore, mating surfaces


20


,


22


may include one, two, three, or a substantially greater number of male shapes


60


and female shapes


62


. For example, the device


10


may have applications in the medical implant field where mating surfaces


20


,


22


containing hundreds or thousands of tongue and groove, or male shapes


60


and female shapes


62


are desirable.




Referring now to

FIG. 13

, a variety of different complex shapes may be used to form male shapes


60


. That is, for every male shape


60


depicted in

FIG. 10

, additional grooves or notches


64


may be made in those male shapes


60


. As shown in

FIG. 14

, where male shapes


60


with notches


64


are used, corresponding female shapes


62


preferably include projections


66


to mate with the notches


64


.




In addition to the above noted complex shapes that may be used, shape additions


68


, such as those shown in

FIG. 15

, may be added to male shapes


60


. Similarly, as shown in

FIG. 16

, female shapes


62


may be provided that also include additional shapes


68


. Where used, the opposing mating surface


20


or


22


includes appropriate indentations or notches (not shown) to accommodate the shape additions


68


.




Referring now to FIGS.


17


.


1


-


17


.


11


, it is a further aspect of the present invention to provide mating surfaces


20


and


22


that include a variety of shapes


70


along the length of the male shapes


60


, as may be desired. For illustration purposes, all of the shapes shown are male shapes


60


. However, it is to be understood that corresponding female shapes


62


are preferably used to mate with the male shapes


60


that may incorporate a simple shape


70


anywhere along its length.

FIG. 17.1

shows a simple shape


70


located on the top and the bottom of the male shape


60


, but with no shape in the middle. The simple shape


70


shown is a half circle on each side of the male shape


60


. However, it is to be understood that the simple shape


70


could take on any form, such as a rectangle, triangle, etc.

FIG. 17.2

illustrates a male shape


60


having two different simple shapes


70


on either side at its top.

FIG. 17.3

illustrates three simple shapes


70


stacked on top of each other along the length of male shape


60


.

FIGS. 17.4

through


17


.


9


illustrate several other possible combinations of simple shapes that may be used. Combinations other than those illustrated are possible and within the scope of the present invention.

FIG. 17.10

illustrates that the male shape


60


may be curved. In addition,

FIG. 17.11

illustrates that a curved male shape


60


may include a simple shape along its length, such as at its end. In sum, male shapes


60


may be contain notches


64


, additional shapes


68


, simple shapes


70


and/or curved members to create a mating surface


20


,


22


. Female shapes


62


preferably mate with male shapes


60


, and incorporate appropriate shapes, such as projections


66


, as maybe required to mate with male shapes


60


.





FIGS. 18



a


and


18




b


illustrate that a upper seal member


12


and lower seal member


14


may include male shapes


60


of variable height along their mating surfaces


20


and


22


, respectively. In a preferred embodiment, a single mating surface is designed to mate with itself. More specifically, a single profile section is produced, cut, and flipped over to mate with itself and form a seal, as illustrated in

FIG. 18



c


. Here, the single profile serves as both the upper seal member


12


and the lower seal member


14


.




Referring now to

FIGS. 19-20

, a modification of the first embodiment is presented, wherein a modified slider


16


′ is used in combination with an upper seal member


12


and a lower seal member


14


to create a seal


17


. Slider


16


′ features a closing portion


72


and an opening portion


74


. As with slider


16


, slider


16


′ is moved along the length of the seal


17


to either close or open the seal


17


. In use, as slider


16


′ is moved along the seal profiles, the closing portion


72


closes the seal portion it passes. Conversely, when slider


16


is moved in the opposite direction, the opening portion


74


opens the seal portion it passes.




Closure of the seal


17


occurs at closing end


72


because upper seal member


12


is placed in confinement with lower seal member


14


, thereby pressing mating surface


20


of upper seal member


12


into the mating surface


22


of lower seal member


14


. More particularly, the mating surface


20


of upper seal member


12


is pressed into the mating surface


22


of lower seal member


14


by upper canted portion


76


of slider


16


′. As this action occurs, lower seal member


14


is held in place by closure bar


48


of slider


16


′.




Canted portion


76


may have a horizontal interior surface


78


. However, canted portion


76


is preferably tilted, or set at a downward angle α relative to a horizontal plane. This downward angle α functions to rotate the upper seal member


12


as its mating surface


20


is pressed into mating surface


22


of lower seal member


14


. This rotation of upper seal member


12


assists in allowing slider


16


′ to move more freely as it is used to zip the seal


17


closed or open. In addition, rotation of upper seal member


12


improves the air and water resisting characteristic of the seal in a closure state, by rotating the male shapes


60


into female shapes


62


, thus improving the contact of their individual surfaces. Male shapes


60


and female shapes


62


used in conjunction with mating surfaces


20


and


22


that are sealed using slider


16


′ may contain notches


64


, projections


66


, additional shapes


68


, simple shapes


70


, as well as all other features previously described for mating surfaces


20


,


22


and their component structures.




Referring now to

FIG. 20

, a series of partial cylindrical shapes


80


are provided for reducing friction between the upper canted portion


76


and the upper seal member


12


. More specifically, the interior surface


78


of upper canted portion


76


preferably includes a series of partial cylindrical shapes


80


that contact the upper surface


47


of the main profile portion


25


of upper seal member


12


. These cylindrical shapes


80


serve to reduce friction between the upper canted portion


76


and upper seal member


12


as upper seal member


12


contacts the upper canted portion


76


. Partial cylindrical shapes


80


are also preferably used along at least a portion of closure bar


48


at the closure portion


72


of slider


16


′. The cylindrical shapes


80


along the interior surface


82


of closure bar


48


reduce friction between the closure bar


48


and the lower seal member


14


.




Slider


16


′ stabilizes and controls the position of lower seal member


14


using closure bar


48


. The aspects of closure bar


48


used in conjunction with slider


16


′ encompass all of the permutations previously described. Without limitation, closure bar


48


may be relatively long, similar to that shown previously in

FIG. 9



a


, or it may be very short and take on the appearance of a prong, as illustrated in

FIG. 9



d


. It may also include an end shape


51


to assist in grabbing lower seal member


14


. This is particularly useful if a relatively short or prong-shaped closure bar


48


is utilized. Regardless of its shape, as with slider


16


, closure bar


48


functions to control the location of lower member


14


within slider


16


′.




Referring again to

FIGS. 19 and 20

, opening portion


74


of slider


16


′ functions to separate upper seal member


12


from lower seal member


14


and open the seal


17


. Opening portion


74


preferably includes one lifting rib


46


′. Lifting rib


46


′ preferably extends in an inclined position from approximately the middle of slider


16


′ to the end of slider


16


′ at the opening portion


74


of the slider


16


′. Opening portion


74


also includes closure bar


48


, which preferably extends the entire length of the bottom of slider


16


′. Closure bar


48


anchors the lower seal member


44


to the bottom of the slider


16


′. As the slider


16


′ is moved in an opening direction in accordance with arrow


84


of

FIG. 19

, the combination of action of lifting rib


46


′ on upper seal member


12


and the closure bar


48


on lower seal member


14


pulls the two seal members


12


and


14


apart, thus opening the seal. The preferable use of one lifting rib


46


′ in slider


16


′ provides a rotation motion to the upper seal member


12


as it is separated from lower seal member


14


. This rotation occurs because the side of the main profile portion


25


adjacent the lifting rib


46


′ is lifted before the side of the main profile portion


25


opposite the lifting rib


46


′. The rotational feature provides for smoother separation of the upper seal member


12


from the lower seal member


14


, and also tends to improve the longevity of seal performance because less friction is induced between the upper seal member


12


and lower seal member


14


during opening. Lifting rib


46


′ may be shaped like a rail, or it may be wedge shaped, as shown in FIG.


20


.




Referring now to

FIG. 21

, an example of a seal


17


comprising upper seal member


12


and lower seal member


14


is shown. Lifting groove


26


is formed under lifting wing


24


at the edge of the main profile portion


25


of upper seal member


12


. Lifting groove


26


receivingly accepts lifting rib


46


′ of slider


16


′.

FIG. 21

also illustrates closure bar groove


32


within lower seal member


14


.




The various seal configurations depicted in

FIGS. 9



a


through


9




o


are applicable to use with slider


16


′. More specifically, in addition to the features already discussed, such as closure bar


48


characteristics and profile mating surfaces


20


,


22


, slider


16


′ may utilize alternate configurations and features than are shown in FIG.


21


. For example, slider


16


′ may incorporate a single top mounted lifting rib (see

FIG. 9



i


), or a side and top mounted lifting rib (see

FIG. 9



j


). Portions of upper seal member


12


beyond the main profile portion


25


may be at the same elevation or a different elevation than lower seal member


14


. Stiffener inserts


54


may also be used in lower seal member


14


when using slider


16


′.




Referring now to

FIGS. 22 and 23

, lifting rib


46


′ is prevented from separating upper seal member


12


from lower seal member


14


by cutting and removing the lifting wing


24


from the upper seal member


12


at the end portion of


30


of seal


17


. Since lifting wing


24


is absent, the opening portion


74


of slider


16


′ is unable to grasp the underside of upper seal member


12


and cause it to separate from lower seal member


14


. This aspect of the invention enables a seal


17


to be formed upon closure, because the entire length of the upper seal member


12


creates a fluid barrier with lower seal member


14


.





FIG. 24

provides an elevation view of slider


16


′ looking toward the front or opening portion


74


the slider


16


′. This view further illustrates lifting rib


46


′ rising in the foreground on an angle from the middle of slider


16


′ to the front end of slider


16


′. Preferably, a groove


88


is formed in slider


16


′ to assist in retaining lower seal member


14


during opening of the seal


17


.




Referring now to

FIG. 25

, a rear elevation view of slider


16


′ is provided. This view depicts the slider


16


′ looking toward the closing portion


72


. Again, lifting rib


46


′ is shown rising toward the top of slider


16


′.





FIG. 26

depicts a the same rear elevation view as shown in

FIG. 25

, but with an upper seal member


12


and a lower seal member


14


disposed within the slider


16


′. This view also depicts lifting wing


24


of upper seal member


12


disposed over lifting rib


46


′. Closure bar


48


anchors lower seal member


14


within slider


16


′, and also provides confinement in conjunction with canted portion


76


at the closing end


38


of slider


16


′ to press mating surface


20


of upper seal member


12


into interlocking position with mating surface


22


of lower seal member


14


. A top surface


90


of upper seal member


12


is shown rising in the background of the slider


16


′ as the upper seal member


12


is forced open at the front end of the slider.




In contrast to

FIG. 26

, a front elevation view of slider


16


′ with upper seal member


12


and lower seal member


14


is shown in FIG.


27


. Here, the function of the opening portion


74


of slider


16


′ is illustrated. Upper seal member


12


has been pulled apart from lower seal member


14


at the opening end


36


of slider


16


′, thereby exposing the bottom surface


92


of upper seal member


12


.




In a further embodiment, the present invention includes a device for sealing a first edge of a first surface of an object with a second edge of a second surface of the object where the first edge is oriented substantially parallel to the second edge, the first and second surfaces are substantially coplanar, and the first surface extends in a direction opposite the second surface. The device includes an upper seal member, a lower seal member, a slider and a plug. The upper seal member is attached to the first edge and has a first mating surface. The lower seal member is attached to the second edge and has a second mating surface. The second mating surface and the first mating surface are releasably interlockable. The slider has a body, a slider interior structure and an exterior tongue and groove portion. The body includes an opening end and a closing end, with the closing end having a confining portion in which the first mating surface of the upper seal member is placed into interlocking contact with the second mating surface of the lower seal member. The slider interior structure cooperates with the first mating surface of the upper seal member, and cooperates with the second mating surface of the lower seal member. The plug has a plug interior structure, and an exterior tongue and groove portion. The plug interior structure cooperates with the first mating surface of the upper seal member, and cooperates with the second mating surface of the lower seal member. In a closing position, the plug interior structure interlocks with the slider interior structure, and the exterior tongue and groove portion of the plug interlocks with the slider tongue and groove portion. When the slider is moved in a direction causing the upper seal member and the lower seal member to pass within the slider from the opening end to the closing end, the slider confines the first mating surface into contact with the second mating surface thereby creating a seal.





FIGS. 28-31

illustrate this embodiment of the seal device


100


. Seal device


100


includes an upper seal member


12


, a lower seal member


14


, a slider


102


and a plug


104


. Slider


102


includes a pull tab


40


, pin


42


and pull tab track


44


. It is an aspect of this embodiment to provide sealing device


100


that may be locked. Accordingly, pull tab


40


preferably includes an aperture


106


that receivingly accepts lock receptacle


108


of plug


104


when the slider


102


is in its closed position. More specifically, plug


104


is a permanent stop that is affixed to the end of seal


17


. To close seal


17


, slider


102


is zipped down the sealing profile


17


of upper seal member


12


and lower seal member


14


, thereby interlocking mating surface


20


of upper seal member


12


with mating surface


22


of lower seal member


14


. Slider


102


is then brought into to its mating closure position


110


with plug


104


, as will be discussed in detail below. Pull tab


40


is then secured with lock receptacle


108


of plug


104


by placing pull tab


40


in a forward position such that lock receptacle


108


passes through aperture


106


of pull tab


40


. Lock receptacle


108


includes a hole


112


that is sized to receive a common travel lock (not shown).




Referring again to

FIGS. 28 and 29

, two perspective views of seal


100


are shown.

FIGS. 28 and 29

depict slider


102


in its closure position


110


with plug


104


, whereby slider


102


and plug


104


make a seal


17


at the end of the seal profile


110


.





FIG. 30

is a cross-sectional view of seal device


100


taken at the side of upper seal member
