Description

Continuous fastening element anti-seepage zipper and daily necessities with opening and closing function

The invention relates to an anti-seepage zipper, in particular but is not limited to a continuous fastening element anti-seepage zipper. The invention also relates to a daily necessities using the anti-seepage zipper.

The most difficult problem to overcome with waterproof zippers is water seepage through the central gap. Therefore, it is known that the focus of patent cases for waterproof zippers is on how to prevent fluid from seeping through the central gap. As shown in the U.S. Patent No. 8,397,353 owned by the applicant of this case, it discloses that a polymer elastic body is poured into a central gap of a continuous loop fastening element zipper to form a covering portion and a filling portion, so that the covering portion occupies the central gap, and after a waterproof layer is adhered to the pair of supporting fabrics, the waterproof layer and the covering portion are divided in the central gap to form a split seam, so that the originally wide central gap is reduced to a smaller split seam, thereby reducing the path for fluid penetration to achieve a waterproof function.

As shown in Figures 1 and 2, they show a cross-sectional view of a conventional anti-leakage zipper with continuous loop fastening elements. The continuous loop fastening elements are a thermoplastic polymer that is heated and formed. The process is such that each individual fastening element has a buckling end c that is expanded on both sides by impact, and is combined with the supporting cloth belt by sewing or weaving. Through the fastening end c The volume is larger than the arrangement gap of the fastening elements, so that the fastening elements in the left and right rows are not easy to slip off after being fastened to each other. Each row of fastening elements of the continuous loop fastening element anti-leakage zipper is provided with a core wire d.

A thermoplastic elastomer is injected into a central gap through a betting process to form a covering part a. The thermoplastic elastomer penetrates into the gaps between the fastening elements to form a caulking part b. The thermoplastic elastomer of the caulking part b mainly fills the space between the fastening ends c of the fastening elements and the core wire d, so that the caulking part b is imprinted with the fastening ends of the fastening elements. The contact surface of the closing end c has a matching shape, in which the fastening depth of the left and right rows of fastening elements after being fastened with each other is e, and the covering part a is divided in the central gap to form a dividing seam w1.

The injection molding force and viscosity of the thermoplastic elastomer during the injection molding process make the filling portion b not only form a contact surface shape that matches the shape of each of the opposite fastening ends c, but also have an irregular edge with a thickness like a film that is easy to peel off from the adhered fastening elements.

As shown in FIG. 2 , when the anti-seepage zipper shown in FIG. 1 is separated and then fastened again after the separation and combination process, the irregular film-like edge of the caulking portion b becomes loose in the separation and combination process after the covering portion a is separated, and is easily peeled off to become an irregular edge that can move freely, thereby piling up to block the mutual fastening of the fastening ends c, so that the fastening ends c of the opposite fastening elements cannot enter the original position where they are tightly matched with the caulking portion b.

Furthermore, each of the larger fastening ends c needs to pass through the narrow arrangement gap between the fastening elements in order to enter the original fastening position. Therefore, the multiple guiding factors caused by the tortuous interlocking paths and angles, as well as the obstruction of the film-like irregular edge of the caulking portion b, will make it difficult for each fastening element to enter the original fastening position. The fastening depth of the fastening elements in the left and right rows after they are fastened with each other becomes shallower, and the fastening depth changes from the fastening depth e in Figure 1 to a fastening depth f shown in Figure 2, where the fastening depth The closing depth f is less than the fastening depth e; and this change turns to expand the dividing seam w1 and becomes a wider dividing seam w2. From Figure 2, it can be clearly seen that the dividing seam w2 is significantly larger than the dividing seam w1, so The anti-leakage function of the covering part a of the anti-leakage zipper is reduced and needs to be improved urgently.

In one embodiment, the daily necessities with the opening and closing function are selected from the group consisting of clothing, carrying devices and camping equipment.

As shown in FIG. 3a and FIG. 3b, two cross-sectional views of the first embodiment of the continuous fastening element anti-seepage zipper 1 of the present invention are disclosed. The anti-seepage zipper 1 is prepared by subjecting an existing zipper to a betting process (shown in FIG. 3a) and a gluing process (shown in FIG. 3b).

The existing zipper includes a pair of support tapes 11 arranged in parallel. Each of the pair of support tapes 11 has a first surface 11a, a second surface 11b opposite to the first surface 11a, an inner edge 11c and an inner edge 11c. There is a central gap 12 between the inner side 11d and the two opposite inner sides 11d. A plurality of continuous fasteners arranged in a row are combined with at least one bonding line 3 on each inner edge 11c of the pair of support cloth straps 11. Element 2.

The two rows of continuous fastening elements 2 each have a top surface 21, a bottom surface 22 and a fastening end 23. The pair of supporting fabric strips 11 are made of warp knitting or woven, and if necessary, they can be made to have elasticity in a warp direction and/or a weft direction, so that each supporting fabric strip 11 has elasticity in the warp direction and/or the weft direction.

The two rows of continuous fastening elements 2 are each formed into a continuous coil shape by heat treatment with polyamide monofilament or polyester monofilament, and a core wire 25 is inserted into each inner cavity 24 between the top surface 21 and the bottom surface 22, and the at least one bonding line 3 is bonded to the inner edge 11c of each supporting fabric belt 11 by sewing, so that the fastening elements 2 of each row are adjacent to the second surface 11b of the corresponding supporting fabric belt 11 with the top surface 21.

In fact, in addition to the aforementioned continuous loop-type fastening element zipper with core wire 25, the zipper can also be selected from the group consisting of a core-free continuous loop-type fastening element zipper, a core-free continuous folding fastening element zipper, and a continuous loop-type fastening element zipper without core wires. Invisible zippers with loop fastening elements and woven zippers with continuous loop fastening elements, etc., but are not limited to this.

As shown in Figure 3a, the betting process is to inject a first thermoplastic elastomer 4 into the central gap 12 to form a filling body 41 when the zipper is in a fastened state, and continue to penetrate into the fastening elements. In each gap 26 between each fastening end 23 of each fastening element 2 and the core line 25 and/or the at least one bonding line 3 of the opposite fastening element 2, a caulking portion 42 is formed. Then the filling body 41 is divided in the central gap 12, and then the zipper is separated and re-fastened in a dividing and closing process to divide into a left filling part 411 and a right filling part 412. The left and right filling parts 411 , 412 each have a free end surface and a first gap 43 between the free end surfaces.

Therefore, the first thermoplastic elastomer 4 is filled in the central gap 12 in a hot-melt state, and penetrates into the fastening ends 23 of the fastening elements 2 and the opposite fastening elements 2 . In the gaps 26 between the core wires 25 and/or the at least one bonding wire 3, a mold die-casting effect similar to casting is produced, so that the gap-filling portion 42 of the first thermoplastic elastomer 4 has the ability to engage with each of the gaps 26. The shape of end 23 matches the contact surface. When the filling body 41 is divided and re-fastened, due to the mutual friction of the fastening elements 2 or the irregular edges of the caulking portion 42, the fastening of the opposite fastening elements 2 is hindered. The end 23 cannot completely return to the original fastening depth that is closely matched with the caulking portion 42 , so that the fastening depth of the fastening elements 2 becomes shallower, which in turn causes the width of the first gap 43 to become larger.

After the aforementioned separation and combination process, the fastening positions of the fastening elements 2 are randomly and fully varied, so that the first slit 43 is naturally opened to a stable width, and then the gluing process is performed. The gluing process is to inject a second thermoplastic elastic body 5 in a hot melt state into the first slit 43 using a glue injection mold having a small glue injection port to form a waterproof body 51. Then, the waterproof body 51 is divided in the first slit 43 to be divided into a left waterproof part 511, a right waterproof part 512, and a second slit 52 between the left waterproof part 511 and the right waterproof part 512, so as to complete the preparation of the waterproof zipper 1.

In addition, in a possible variant embodiment, when the fastening position of each fastening element 2 undergoes random and sufficient variation, and the first gap 43 is naturally opened to a stable width, the zipper is separated to The glue filling process is carried out. The glue filling process is to adhere the left anti-seepage part 511 of the anti-seepage body 51 to the free end surface of the left filling part 411 in an adhesive manner, and also adhere the right anti-seepage part 511 of the anti-seepage body 51 to the free end surface of the left filling part 411 . The seepage part 512 is adhered to the free end surface of the right filling part 412 in an adhesive manner, and then the zipper is pulled closed to form a second gap 52 between the left anti-seepage part 511 and the right anti-seepage part 512. To complete the preparation of the anti-leakage zipper 1.

Please refer to Figure 3c, which reveals a cross-sectional view of the second embodiment of the continuous fastening element anti-leakage zipper of the present invention. In the second embodiment, the zipper after the depositing process is separated, and then the first surface 11a of the left support tape 11 and the first surface 11a of the right support tape 11 are adjacent and closely connected together. , to form a combined free end surface composed of the left filling part 411 and the right filling part 412 . Next, the glue filling process is carried out. The glue filling process is to apply the second thermoplastic elastomer 5 in a molten state and adhere it to at least a part of the free end surface of the combination to form an anti-seepage body 51, and then divide the anti-seepage body 51. The leakage body 51 is removed, and the zipper is fastened again, so that the zipper has a left anti-seepage part 511, a right anti-seepage part 512 and a second gap 52 as shown in Figure 3b to complete the preparation of the anti-seepage zipper 1.

In addition, in another equivalent embodiment, the second thermoplastic elastomer 5 can also be prepared in advance as a long strip-shaped anti-seepage body 51, and then adhered to the free end surface of the assembly by heat welding or adhesive bonding. At least part of it is to form an anti-seepage body 51, and then the anti-seepage body 51 is divided and the zipper is refastened so that the zipper has a left anti-seepage part 511, a right anti-seepage part 512 and a right anti-seepage part 511 as shown in Figure 3b. The second gap 52 is used to complete the preparation of the anti-leakage zipper 1 .

It can be clearly seen from Figure 3b that when the anti-seepage zipper 1 is in a fastened state, the anti-seepage body 51 at least fills a part of the first gap 43, and the left anti-seepage part 511 and the right anti-seepage part 512 are mutually exclusive. The contact causes the second gap 52 to be in a closed state, so as to obtain a better anti-seepage effect against fluids, such as liquids, in the central gap 12 . If the anti-leakage zipper 1 is subjected to water-repellent processing, the water-repellent agent is impregnated on at least one side of the pair of support tapes, so that the pair of support tapes 11 of the anti-seepage zipper 1 has a water-repellent function. Furthermore, if the pair of supporting cloth tapes 11 is made of water-impermeable material, the pair of supporting cloth tapes 11 can have a water-proof function, so as to further improve the central gap 12 of the anti-seepage zipper 1 and the pair of supporting cloth tapes. 11 all have anti-seepage function.

In this embodiment, the second thermoplastic elastomer 5 and the first thermoplastic elastomer 4 may be the same or different thermoplastic elastomers. The thermoplastic elastic system is selected from polyester elastomer, polyamide elastomer, polyurethane elastomer, polyolefin elastomer or equivalents, but is not limited thereto.

Subsequently, the anti-seepage body 51 is divided into a left anti-seepage part 511 , a right anti-seepage part 512 and a third part located between the left and right anti-seepage parts 511 and 512 through a dividing process. Two gaps 52. Since the first gap 43 is already very narrow, the position of the second gap 52 may not be consistent with the center line of the first gap 43 , but it will not affect the anti-leakage function of the anti-leakage zipper 1 .

Furthermore, if the anti-leakage zipper 1 is subjected to water-repellent processing, the water-repellent agent is at least impregnated on each of the second surfaces 11b of the pair of support tapes and the continuous fastening elements 2, so as to further make the anti-leakage zipper 1 water-repellent. The pair of supporting cloth tapes 11 of the zipper 1 has a water-repellent function.

As shown in Figure 10, it reveals a cross-sectional view of the tenth embodiment of the continuous fastening element anti-leakage zipper of the present invention. The difference between the tenth embodiment and the ninth embodiment is that in the tenth embodiment, a waterproof layer 53 is added to cover the first surface 11a and the anti-seepage body 51 corresponding to the pair of support cloth straps 11, and then the waterproof layer 53 is divided. Layer 53 and the anti-seepage body 51, so that the waterproof layer 53 and the anti-seepage body 51 together form a left anti-seepage part 511, a right anti-seepage part 512 and a left anti-seepage part 511 and the right anti-seepage part. The second gap 52 between 512.

The waterproof layer 53 can be selected from film lamination or thermoplastic elastomer coating. The individual thicknesses of the anti-seepage body 51 and the filling body 41 in the central gap 12 do not need to be particularly limited. Since the first gap 43 is already very narrow, the position of the second gap 52 may not be consistent with the center line of the first gap 43 , but it will not affect the anti-leakage function of the anti-leakage zipper 1 . If the second surfaces 11b of the pair of support tapes 11 and the fastening elements 2 are subjected to water-repellent processing, the pair of support tapes 11 of the anti-seepage zipper 1 can further have a water-repellent function.

What's more, the waterproof layer 53 can also be installed after the anti-seepage body 51 is divided, and then the waterproof layer 53 is divided separately to improve the anti-seepage effect of the anti-seepage zipper 1 .

Wherein, the material of the pair of supporting cloth tapes 11 can be selected from polyester fiber, polyamide fiber or polyolefin fiber, etc., so that it is similar to the material or polarity of the impermeable body 51. For example, polyester elastomer is used in materials containing The pair of supporting cloth tapes 11 of polyester fiber, polyamide elastomer and polyurethane elastomer are used in the pair of supporting cloth tapes 11 containing polyamide fiber, and the polyolefin elastomer is used in the pair of supporting cloth tapes 11 containing polyethylene or polypropylene fibers. The pair of support cloth tapes 11 thereby improves the bonding fastness of the waterproof layer 53 and the pair of support cloth tapes 11 .

If necessary, at least one of the first surfaces 11a and the second surfaces 11b of the pair of supporting fabrics 11 may be pre-impregnated with an adhesive, such as water-based polyurethane or solvent-based adhesive, to improve the bonding strength of the waterproof layer 53. Furthermore, the pair of supporting fabrics 11 may also be pre-coated or impregnated with an adhesive, such as reactive hot melt adhesive, such as moisture-hardening polyurethane, on each of the first surfaces 11a of the pair of supporting fabrics 11 to improve the bonding strength of the waterproof layer 53. The waterproof layer 53 may be selected from a film laminate or a thermoplastic elastomer coating as required.

Furthermore, the weaving structure of the pair of supporting fabrics 11 can be selected to have elasticity in a longitudinal direction or a longitudinal direction to enhance the flexibility and plane bendability of the pair of supporting fabrics 11.

In addition, at least the second surfaces 11b of the pair of supporting cloth belts 11 and the fastening elements can be selectively treated with a water-repellent agent, which can prevent fluids such as liquids from passing through the first gap 43 and the second gap. 52 to further enhance the anti-seepage effect of the anti-seepage zipper 1.

Therefore, through the implementation of this case, the effects gained by it are as follows:

1. Overcome the problem that the dividing seam of the conventional continuous fastening element anti-leakage zipper cannot be reduced, thus greatly improving the anti-leakage function.
