In one example, the slide fastener sealing system includes a separating slide fastener in which a first end overlaps and is secured to a second end such that a sealing zone is located between the overlapping ends of the slide fastener. The sealing system also includes in this example a sealing member that can be secured to the slide fastener in a removable fashion with a portion of the sealing member located in the sealing zone to seal against fluid penetration through the sealing zone.

Description

FIELD OF THE INVENTION

This application relates to slide fastener sealing systems and related methods that can be used in applications involving liquids or potentially harmful gases.

BACKGROUND

Zippers and other slide fasteners can be used to fasten components that may be used in applications that may involve liquids and/or potentially harmful gases. As some non-limiting examples, zippers and other slide fasteners may be used in waterproof garments, laboratory suits, boat covers, and other applications as desired. As one non-limiting example, zippers and other slide fasteners can be used to fasten components of a waterproof garment together in a removable fashion, to allow a user to relatively easily put the garment on and take it off. In applications that may involve liquids and/or potentially harmful gases, the slide fastener should ideally not detract from the ability of the article (e.g., the waterproof garment) to resist or minimize passage of fluid and/or gas into or out of the article. While there are some sealing zippers and zipper systems on the market that have been used for this purpose, available options all have disadvantages, and there remains room for improvement. This patent describes improved slide fastener sealing systems and related methods.

DETAILED DESCRIPTION

Several examples of slide fastener sealing systems and related methods are described below. The example illustrated in FIGS. 1-11 will be discussed first.

Structure and Relationship of Parts

Referring to FIG. 10, the sealed zipper assembly of FIGS. 1-11 includes a first zipper segment 12 and a second zipper segment 14 in overlapping relation to create a sealing zone 16. Referring to FIG. 6 and FIG. 9, sealing zone 16 can be viewed as forming a tunnel. Referring to FIG. 10, in this regard, sealing zone 16 has an exterior opening 18 and an interior opening 20. Referring to FIG. 9 and FIG. 10, a sealing element 22 is positioned in sealing zone 16 to prevent leakage between first zipper segment 12 and second zipper segment 14. Referring to FIG. 11, sealing element 22 is illustrated. Referring to FIG. 9 and FIG. 10, sealing element 22 is resiliently deformable and is compressed within sealing zone 16 by first zipper segment 12 and second zipper segment 14. Referring to FIG. 10, it will be noted that with this first example, first zipper segment 12 and second zipper segment 14 are part of a single interlocking zipper fastener 24 and create a single sealing zone, previously identified as sealing zone 16. As will hereinafter be illustrated and described with reference to other examples, there can be more than one interlocking zipper fastener and more than one sealing zone.

Referring to FIG. 1 through FIG. 5 and FIG. 8, interlocking zipper fastener 24 has a first series of interlocking teeth 26 supported on a band 28 and a second series of interlocking teeth 30 supported on a band 32. At least one slider 34 is provided. Referring to FIG. 7 and FIG. 10, interlocking zipper fastener 24 has a first end 36 that serves as first zipper segment 12 and a second end 38 that serves as second zipper segment 14 in this embodiment.

Referring to FIG. 2, a garment body 40 made with waterproof fabric consists of a first or upper discrete body component 42 and a second or lower discrete body component 44. Interlocking zipper fastener 24 is in a circular configuration that enables first discrete body component 42 to be separated from second discrete body component 44. Referring to FIG. 2, band 28 supporting first series of interlocking teeth 26 constituting a first half of interlocking zipper fastener 24 is secured to first discrete body component 42 in a generally circular configuration to form a first half of first zipper segment 12 and a first half of second zipper segment 14 in overlapping relation. Similarly, band 32 supporting second series of interlocking teeth 30 constituting a second half of interlocking zipper fastener 24 is secured to second discrete body 44 component in a generally circular configuration to form a second half of the first zipper segment 12 and a second half of the second zipper segment 14 in overlapping relation.

Referring to FIG. 3, slider 34 is used to slide along interlocking zipper fastener 24 in a first direction to bring first series of interlocking teeth 26 and second series of interlocking teeth 30 into engagement as illustrated in FIG. 1. Referring to FIG. 4, slider 34 slides along interlocking zipper fastener 24 in a second direction to disengage first series of interlocking teeth 26 and second series of interlocking teeth 30 to disengage interlocking zipper fastener 24, as illustrated in FIG. 2. Referring to FIG. 6, FIG. 7, FIG. 9 and FIG. 10, as slider 34 interlocks first series of interlocking teeth 26 and second series of interlocking teeth 30, it completes first zipper segment 12 and second zipper segment 14, the overlapping of which creates sealing zone 16. Sealing zone 16 is then ready to receive sealing element 22. Referring to FIG. 11, sealing element 22 has ridges 46 that assist in sealing. Sealing element 22 also has a first channel 48 on a first face 50 and a second channel 52 on a second face 54. Referring to FIG. 9, First channel 48 receives interlocked teeth 56 of first zipper segment 12 and second channel 52 receives interlocked teeth 58 of second zipper segment 14.

Operation

Referring to FIG. 2, band 28 supporting first series of interlocking teeth 26 constituting a first half of interlocking zipper fastener 24 is secured to first discrete body component 42 in a generally circular configuration to form a first half of first zipper segment 12 and a first half of second zipper segment 14 in overlapping relation. Band 32 supporting second series of interlocking teeth 30 constituting a second half of interlocking zipper fastener 24 is secured to second discrete body 44 component in a generally circular configuration to form a second half of the first zipper segment 12 and a second half of the second zipper segment 14 in overlapping relation. Referring to FIG. 3, slider 34 slides along interlocking zipper fastener 24 in a first direction to bring first series of interlocking teeth 26 and second series of interlocking teeth 30 into engagement as illustrated in FIG. 1. Referring to FIG. 6 and FIG. 7, as slider 34 interlocks first series of interlocking teeth 26 and second series of interlocking teeth 30, it completes first zipper segment 12 and second zipper segment 14 the overlapping of which creates sealing zone 16. Referring to FIG. 9 and FIG. 10, sealing element 22 is compressed within sealing zone 16 by first zipper segment 12 and second zipper segment 14.

Variations

There will hereinafter be described several variations that may be made to the first example described above.

The first example included a single sealing element 22. Referring to FIG. 15, there is illustrated an alternative sealing element 122 that has a first seal component 124 and a second seal component 126. Referring to FIG. 12, first seal component 124 is wedged into and held by friction or otherwise secured to first discrete body component 42. Second seal component 126 is wedged into and held by friction or otherwise secured to second discrete body component 44. Referring to FIG. 13 and FIG. 14, when interlocking zipper fastener 24 is closed, first seal component 124 and second seal component 126 are forced together to form sealing element 122 which fills sealing zone 16.

In the first example discussed above, sealing element 22 was held in place by friction and was removable. Referring to FIG. 16 and FIG. 17, alternative sealing element 222 has a fabric strip 224 moulded into the elastomeric foam. Fabric strip 224 is used to secure alternative sealing element 222 to first discrete body component 42. This is done by stitching through fabric strip 224. Fabric strip 224 serves to anchor alternative sealing element 222 to first discrete body component 42 in a desired position where sealing zone 16 is formed by the overlapping of first zipper segment 12 and second zipper segment 14 of interlocking zipper fastener 24. It will be appreciated that there are other ways to secure alternative sealing element within sealing zone 16.

In the first example discussed above, sealing element 22 was elastomeric foam. Referring to FIG. 18 and FIG. 19 an alternative sealing element 322 is illustrated. Referring to FIG. 18, sealing element 322 is a plug 324 that is suspended by a tether 326 from slider 34 when not in use. Referring to FIG. 19, plug 324 is intended to be inserted into exterior opening 18 of sealing zone 16 to seal sealing zone 16. It is preferred that plug 324 have a surface profile, such as ribs or ridges, to enhance both the sealing capacity and the holding capacity of plug 324. It will be appreciated that there are other raised surface profiles that would similarly serve this purpose.

In the first example discussed above, first zipper segment 12 and second zipper segment 14 are positioned substantially parallel to interlocking zipper fastener 24. Referring to FIG. 22, first zipper segment 12 and second zipper segment 14 which form sealing zone 16, can be configured so that they project outwardly or radially from interlocking zipper fastener 24.

In the first example discussed above, there was only one interlocking zipper fastener 24 and only one sealing zone 16. Referring to FIG. 23, there is shown a configuration that has more than one interlocking zipper fastener 24 and more than one sealing zone 16. With this configuration, first end 36 of one interlocking zipper fastener 24 serves as first zipper segment 12 and second end 38 of another interlocking zipper fastener 124 serves as second zipper segment 14 to create a first sealing zone 16. In addition, first end 36 of interlocking zipper fastener 124 serves as first zipper segment 12 and second end 38 of interlocking zipper fastener 24 serves as second zipper segment 14 to create a second sealing zone 116. It will be appreciated that although two interlocking zipper fasteners 24 and 124 have been illustrated in a circular configuration more than two interlocking zipper fastener could also be arranged in a circular configuration in a like manner.

It is not unusual for a garment intended for use in water, such as garment body 40 to have air transfer valves, to provide for air movement. Referring to FIG. 24, alternative sealing element 422 is shown with an air transfer tube 424 extending through the body of alternative sealing element 422. Air transfer tube 424 allows for movement of air in and out of garment body 40. When garment body 40 is to be submerged in water or another liquid, a closure valve 426 can be used to close air transfer tube 424.

In the first example discussed above, sealing element 22 was compressed. Referring to FIG. 25, a bladder like alternative sealing element 522 is shown which is expandable like a balloon. Alternative sealing element 522 has a tube 524 into which a user may blow to inflate alternative sealing element 522 and a closure valve 526 that is to maintain air pressure within alternative sealing element 522. When expanded, alternative sealing element 522 expands to occupy sealing zone 16.

Another alternative sealing element is positioned between two clamping elements with at least one of the clamping elements being movable toward and away from another of the clamping elements. As the clamping elements are moving closer together, the sealing element is forced outwardly to seal the sealing zone. Referring to FIG. 26, one such clamping configuration is illustrated. Alternative sealing element 622 has a bolt 624 that runs through it lengthwise. There is a nut 626 on one end of the bolt 624 and a twist knob 628 on the other end of bolt 624. Nut 626 serves as one clamping element and twist knob 626 serves as another clamping element. Turning twist knob 628 causes axial movement that compresses alternative sealing element 622 between twist knob 628 and nut 626. When compressed, alternative sealing element 622 expands outwardly increasing the circumference of alternative sealing element 622 until alternative sealing element 622 seals the sealing zone.

Cautionary Warnings

It will be appreciated that not all zippers can function in a liquid environment. In order to avoid leakage, one may wish to use a waterproof zipper. It will also be appreciated that there are a number of different styles of waterproof zippers.

In order for the sealing elements described above to be effective, one may wish to take extra precautions to address potential leakage points along stitches and seams.

Referring to FIG. 1, stitches 50 are used to secure interlocking zipper fastener 24 in place. Referring to FIG. 5, waterproof tape 52 is heat sealed or secured by adhesive to reverse side of stitches 50 to prevent liquids weeping through stitches 50.

Referring to FIG. 20 and FIG. 21, sealing zone 16 has edge seams 54 that are subject to leakage. Referring to FIG. 20, leakage can be addressed by sealing edge seams 54 with pliable edge moulding 56. Referring to FIG. 21, leakage can also be addressed by sealing edge seams 54 by using a bead 58 of polymer caulking compound.

Improved Slide Fastener Sealing System

FIGS. 27 to 41 show another example of a slide fastener sealing system 1000, featuring improvements, modifications, and alternatives to the slide fastener sealing systems described above. The system 1000 shown in FIG. 27 includes a slide fastener 1002 and a sealing member 1004. The slide fastener sealing system 1000 may be incorporated into multi-piece waterproof garments or other multi-piece sealed systems to allow the pieces of those systems to be fastened together in a removable fashion while still providing for sealing of those systems against fluid leakage through the slide fastener sealing system.

Slide Fastener

FIGS. 28 and 29 show the slide fastener 1002 of FIG. 27 in more detail, with FIG. 29 showing a cross-section of the slide fastener. The slide fastener 1002 includes two tapes 1006, with each tape having a series of fastening elements 1008 positioned along the tape. Although not shown in FIGS. 28 and 29, the slide fastener 1002 may include a slider (similar to, for example, the slider 34 shown in FIG. 1), which is configured to engage and disengage the fastening elements 1008 of the two tapes 1006 when slid along the slide fastener 1002.

As shown in FIG. 28, one end of the two tapes 1006 overlaps the other end of the two tapes 1006 (only the overlapping and adjacent length of the slide fastener is shown in these Figures). The slide fastener 1002 of FIGS. 28 and 29 may be formed in a loop, similar to the loop shown in FIG. 7. Although FIG. 7 shows a slide fastener formed in a circular loop, other looped shapes and configurations are also possible. As shown in FIGS. 28 and 29, the overlapping ends of each tape 1006 are secured together along their edges 1010. This may be done by heat sealing the edges of the ends of the tape together or in other manners. As shown in FIG. 29, the slide fastener 1002 includes side seals 1012 (discussed later below) in the interior where the overlapping ends of the tapes 1006 are joined together.

The slide fastener shown in this example is a separating slide fastener, in which the two tapes 1006 may be completely detached from one another and reattached in normal use. As shown in FIGS. 28 and 29, the separating slide fastener includes a retaining box 1014 at the end of the series of fastening elements 1008 of one of the tapes 1006, and an insert pin 1016 at the end of the series of fastening elements 1008 of the other tape 1006. The insert pin 1016 may be inserted into retaining box 1014 and the slider slid along the fastening elements 1008 to fasten the two tapes 1006 together. The slider may be slid in an opposite direction and the insert pin 1016 removed from the retaining box 1014 to separate the two tapes 1006 from one another.

As shown in FIG. 29, with the slide fastener 1002 looped with one end of the tapes 1006 overlapping the other end and the edges 1010 of the tapes 1006 secured together, a passage 1018 is formed between the overlapping ends. When the slide fastener 1002 is incorporated into a waterproof garment or other sealed system, the passage 1018 is a place in which water, another liquid, or a gas could penetrate into or out of the system via open ends of the passage 1018 where the tapes 1006 are no longer overlapping. As discussed further below, the passage 1018 defines a sealing zone for receiving sealing member 1004 in order to resist fluid penetration through the passage 1018.

Sealing Member

FIGS. 30-37 show an example of a sealing member 1004 that may be inserted into the passage 1018 of slide fastener 1002 to resist fluid penetration through the passage 1018. In this particular example, the sealing member 1004 includes three components: a connector 1020, a sealing body 1022, and a sealing body actuator 1024.

The connector component 1020 is shown disassociated from the rest of the sealing member assembly 1004 in FIGS. 34 and 35. The connector 1020 is configured to connect the sealing member 1004 to the slide fastener 1002. In the particular example shown in FIGS. 34-35, the connector 1020 includes a resilient hook 1026 that hooks around an end of the tapes 1005 of the slide fastener 1002. As shown in FIG. 35, the resilient hook 1026 includes a ramped surface 1028, a recess 1030, and a protrusion 1032 that engage and receive the retaining box 1014 and insert pin 1016 of the slide fastener 1002 to secure the sealing member 1004 in place on an end of the slide fattener tapes 1006. The connector 1020 also includes an aperture 1034 for receiving sealing body actuator 1024 in a sliding fashion, as discussed in further detail below.

The connector 1020 shown in FIGS. 34 and 35 includes arms 1036 that connect and anchor the connector 1020 to the sealing body 1022, which may be molded onto the connector 1020 during manufacture. The sealing body 1022 may be formed from a soft, deformable material. The sealing body 1022 may have a base shape in which the sealing body 1022 is not deformed. As discussed in greater detail below, the sealing body 1022 may be selectively deformed and expanded from the base shape using the sealing body actuator 1024. The sealing body 1022 is shown disassociated from the rest of sealing member assembly 1004 in FIG. 36. The sealing body 1022 has outer sidewalls 1038 that are shaped and otherwise configured to conform to the shape of side seals 1012 of the slide fastener 1002 (see, for example, FIGS. 40-41 discussed further below). The sealing body includes grooved top and bottom surfaces 1040 configured to receive and conform to the fastening elements 1008 of the slide fastener 1002, and also to provide clearance through which the slider can move. As with the connector 1020, the sealing body 1022 includes an aperture 1042 for receiving sealing body actuator 1024 in a sliding fashion.

The sealing body actuator 1024 is shown disassociated from the rest of the sealing member 1004 in FIG. 37. As shown in FIG. 37, the sealing body actuator 1024 tapers between a thicker end 1044 and a narrower end 1046. When the thicker end 1044 is moved further into the sealing body 1022, the deformable sealing body 1022 will expand from its base shape to accommodate the thicker end 1044. Conversely, when the narrower end 1046 is moved further into the sealing body 1022, the deformable sealing body 1022 will contract back towards its base shape. It will be appreciated that the deformable sealing body 1022 may not return completely to its base shape when the narrower end 1046 is in the sealing body 1022. The sealing body actuator 1024 shown in FIG. 37 can be connected towards the narrower end 1046 to a pull, such as the tether 325 shown in FIG. 18. The pull may be used to draw the thicker end 1044 of the sealing body actuator 1024 into the sealing body 1022, to deform the sealing body 1022 and cause it to expand. As shown in FIG. 37, the sealing body actuator 1024 includes an aperture 1048 to which the pull may be connected. As also shown in FIG. 37, the sealing body actuator 1024 includes a grip 1050 at its thicker end 1044, which may be used to draw the thicker end 1044 of the sealing body actuator 1024 from the sealing body 1022, causing the sealing body 1022 to contract. The narrower end of actuator 1046 may also extend beyond the end of the sealing body 1022, allowing the actuator 1024 to be pushed to move the narrower end 1046 of the actuator 1024 into the sealing body 1022 to contract the sealing body 1022.

Although not specifically shown in the Figures, the sealing body actuator 1024 and/or the pull connected to the actuator 1024 may be sufficiently long such that it extends beyond the end of the passage 1018 formed by the overlapping ends of the slide fastener 1002 and/or is otherwise accessible from the outside of the garment or other waterproof construct in which the slide fastener sealing system 1000 is being used.

Method of Use

The slide fastener sealing system 1000 of FIGS. 27 to 41 may be used by connecting the sealing member 1004 to an end of the slide fastener 1002, sliding the slide fastener's slider to engage the fastening elements 1008 and close the slide fastener 1002 over the top of the sealing member 1004, and actuating the sealing body actuator 1024 to deform sealing body 1022 such that it expands. Actuating the sealing body actuator 1024 may conform the sealing body 1022 to the side seals 1012 and interiors of the tapes 1006, thereby sealing the passage 1018 to resist fluid penetration therethrough. Actuating the sealing body actuator 1024 may also conform the sealing body 1022 to the elements of the slide fastener, which may form a seal with the elements of the slide fastener to resist fluid penetration therethrough.

FIGS. 38-41 show the sealing member 1004 installed in the passage 1018 of the slide fastener 1002, such that the sealing body 1022 of the sealing member 1004 is adjacent the side seals 1012 of the slide fastener 1002 in a sealing zone of the passage 1018. Both the sealing body 1022 and the side seals 1012 are made of relatively soft, compliant material to facilitate the formation of a fluid-tight seal that plugs the interior of the passage 1018. In one example, the sealing body 1022 includes a material having a Shore hardness in the range of and including OO-30 to Shore D-65, such as a hardness in the range of Shore A-0 to Shore-A 30, such as hardness in the range of and including Shore-A 0 to Shore-A 10. In one non-limiting example, the sealing body 1022 may include a Shore-A 2 elastomeric material. In one example, the side seals 1012 include material having a Shore hardness in the range of and including OO-30 to Shore D-65, such as a hardness in the range of and including Shore-A 30 to Shore-A 90, or in some instances in the range of and including Shore-A 50 to Shore-A 70. The side seals may include a Shore-A 60 urethane material. Shore hardness may be measured, for example, using a durometer and by following the testing procedures set out in ASTM D2240.

Performance

The slide fastener sealing system 1000 of FIGS. 27 to 41 may be relatively impermeable to penetration by fluids, including liquids and/or gasses. The slide fastener 1002 itself may be a waterproof zipper such as, for example, the YKK® AQUASEAL® zipper. As described above, the sealing member 1004 may be used to resist penetration by fluids through a passage 1018 between overlapping ends of the slide fastener 1002 that are secured together to form a passage.

For example, the slide fastener sealing system 1000 may resist fluid penetration at a pressure of at least 1 PSI for 20 seconds. In another example, the slide fastener sealing system 1000 may resist fluid penetration at a pressure of at least 4 PSI for 20 seconds. In another example, the slide fastener sealing system 1000 may resist fluid penetration at a pressure of at least 6.5 PSI for 20 seconds. In another example, the slide fastener sealing system 1000 may resist fluid penetration at a pressure between 1 PSI and 6.5 PSI for 20 seconds. In these examples, the slide fastener sealing system 1000 is resistant to fluid penetration through the slide fastener 1002 itself and through the passage 1018 in which the sealing member 1004 is positioned.

Hydrostatic pressure testing methods may be used to measure resistance to fluid penetration, for instance the hydrostatic pressure testing method set out in Section 7.9 of A-A-55634C Commercial Item Description for Zippers (Fasteners, Slide Interlocking) authorized by the General Services Administration of the United States Federal government (Oct. 30, 2019 version).

FIG. 42 schematically illustrates an example of a hydrostatic pressure testing method. It should be noted that FIG. 42 shows a generic zipper sample, and does not specifically show a slide fastener sealing system including a slide fastener and a sealing member. To test a slide fastener sealing system including a slide fastener and a sealing member, such as the slide fastener sealing system shown in FIG. 27, a length of sample such as what is shown in FIG. 27 may be installed in the testing apparatus of FIG. 42, with the slide fastener in a closed configuration, the sealing member positioned in the passage formed by the overlapping ends of the slide fastener, and the sealing body in an expanded configuration inside the passage. To perform the test, the sample is installed in the testing apparatus such that it is sealed at all of its edges by gaskets, is then immersed in water (e.g. the entire sample is covered to a depth of approximately 1 inch), and is then subjected to air pressure for a certain length of time while the top of the sample is observed for air leaks (e.g. bubbles).

The sealing elements described herein may be constructed from various materials suitable for selectively forming a seal with another component, and the sealing elements are not limited to elastomeric foam. As some non-limiting examples, in other embodiments the sealing elements may be various elastomeric deformable materials, a thermoplastic elastomer, combinations thereof, or other various materials as desired.

While the slide fastener sealing systems described herein are discussed in the context of a waterproof garment, they are by no means so limited. Instead, the slide fastener sealing systems may be used in other applications that may involve liquid and/or potentially harmful gases, including but not limited to boat covers, laboratory suits, bags, cases, and other applications as desired. Moreover, the slide fastener sealing systems may be used in other applications that do not necessarily involve liquid and/or potentially harmful gases.
