Abstract
A water-tight and air-tight zipper includes two elastically water-tight strips. The water-tight strips have two water-tight layers. Each water-tight layer is individually provided with a tooth row which is sewn on the correlative side thereof. The two tooth rows both pass through a zipper pull and are corresponding to each other, thereby engaging the two tooth rows with each other and forcing edges of the two water-tight strips to be sealed by using the elasticity of water-tight strips and pulling the zipper pull, and then completely air-tight and water-tight. The tooth rows are directly sewn on the water-tight strips, and thus a water-tight and air-tight zipper can be manufactured by a simple manner, thereby substantially simplifying the manufacturing process.
Description
- The present invention relates to a water-tight and air-tight zipper, and more particularly to a water-tight and air-tight zipper which can be manufactured by a simple manner.
- In conventional waterproof and airtight zipper, the fastener elements are sewn or connected onto conventional tapes (or strips) which are made by weaving or knitting synthetic resin fiber (such as polyamide and polyester fiber) or cotton. Since the tapes are not waterproof and airtight and stretchable, there are variety of treatments need to be performed on the tapes to result in waterproof and airtight effects. For example: U.S. Pat. No. 5,437,888 disclosed the dip-coating method by applying polyurethane resin to cover the tapes and fastener element; U.S. Pat. No. 6,519,826 using injection molding method by applying the thermoplastic polyurethane to cover the tapes and fastener elements; U.S. Pat. Nos. 4,580,321 and 4,823,446 and 4,888,859 and 6,343,408 using heating-press method applying the plastic elastomeric resin to cover the tapes; U.S. Pat. No. 6,427,294 using lamination and heating-press method applying two different melting point resin films to cover the tapes. The zip fasteners of the above prior arts are waterproof and airtight but still not stretchable. U.S. Pat. No. 4,607,416 described the non-stretchable tapes of zip fastener are susceptible to separation to create a leakage path along the confronting edges under transverse stresses or pressure and disclosed a fluid-tight slide fastener having a stretchable property on the tape and yieldingly takes up the transverse stresses to prevent the fastener from separation, the tape is made from the stretchable material threads such as spandex by weaving or knitting, and the tape are applied additional waterproof treatments as the above prior arts.
- It is an object of the present invention provides a water-tight and air-tight zipper which can be manufactured by a simple manner.
- In order to achieve the foregoing objects, the present invention provides a water-tight and air-tight zipper comprising two elastically water-tight strips. The water-tight strips have upper and lower water-tight layers, wherein each upper water-tight layer is individually provided with a zipper mechanism which is sewn on the correlative side of the upper water-tight layer, each lower water-tight layer is connected to the upper water-tight layer for sealing the gap between the two tooth row which is sewn on the upper water-tight layer, thereby forcing edges of the two water-tight strips to be sealed by using the elasticity of water-tight strips and pulling a zipper pull, and then completely air-tight and water-tight. The tooth rows are directly sewn on the water-tight strips, and thus a water-tight and air-tight zipper can be manufactured by a simple manner, thereby substantially simplifying the manufacturing process.
- It is another object of the present invention provides a water-tight and air-tight zipper including water-
tight strips 10 being elastic, whereby the zipper is applied to an flexible, foldable or continuously flexible object. - The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

FIG. 11 is a cross sectional view of a water-tight and air-tight zipper according to the eighth embodiment of the present invention. - Referring to
FIGS. 1 and 2 , they depict a water-tight and air-tight zipper 1 according to an embodiment of the prevent invention. Thezipper 1 includes two elastically water-tight strips 10 (such as rubber strip, nylon strip, etc.). The water-tight strips 10 have two water-tight layers 11 (i.e. upper and lower water-tight layers 11), wherein each upper water-tight layer 11 is individually provided with atooth row 12 of zipper mechanism which is sewn on the correlative side of the upper water-tight layer 11, andstitches 111 are adapted for mounting thetooth row 12 to the upper water-tight layer 11. Each lower water-tight layer 11 is connected to the upper water-tight layer 11 for sealing the gap between the twotooth row 12 which is sewn on the upper water-tight layer 11, thereby having water-tight and air-tight functions. Also, acore rope 121 is individually disposed in thetooth rows 12. The twotooth rows 12 have a plurality ofteeth 13, and there is a proper tooth distance betweenadjacent teeth 13. The twotooth rows 12 both pass through azipper pull 14 and are corresponding to each other. Areceiving space 15 is formed in eachtooth 13, and eachtooth 13 includes a connectingportion 16 disposed at the front end thereof. The size of thereceiving space 15 is bigger than that of the corresponding connectingportion 16 of theteeth 13 of the twotooth rows 12. - Referring to
FIGS. 2 and 3 , they depict the combined and uncombined structures of the above-mentioned zipper. When the twotooth rows 12 are engaged with each other by pulling azipper pull 14, the connectingportions 16 of the twotooth rows 12 can be engaged with the corresponding tooth distance betweenteeth 13 of the twotooth rows 12, whereby the connectingportions 16 is received in thereceiving space 15 so as to generate a cohesive force. The cohesive force forcesedges 112 of the two water-tight strips 10 to be sealed. There is no gap formed between theedges 112 of the two water-tight strips 10 (shown inFIG. 2 ) because the two water-tight strips 10 are elastic, thereby being completely air-tight and water-tight. For above reason, thetooth rows 12 are directly sewn on the water-tight strips 10, and thus a water-tight and air-tight zipper can be manufactured by a simple manner, thereby substantially simplifying the manufacturing process. Moreover, the water-tight strips 10 are elastic, whereby thezipper 1 is applied to a flexible, foldable or continuously flexible object. - Referring to
FIGS. 3 and 4 , theteeth 13 can be continuously oval-shaped teeth 13 (or non-continuously oval-shaped teeth 13 orteeth 13 of non-continuous shape) or continuously rectangular teeth 13 (or non-continuouslyrectangular teeth 13 orteeth 13 of non-continuous shape) (shown inFIG. 4 ). The width of upper water-tight layer 11 is smaller than that of the lower water-tight layers 11, or the width of lower water-tight layer 11 can be smaller than that of the upper water-tight layers 11. - Referring to
FIG. 5 , the water-tight strips 10 have one water-tight layer 11. The water-tight layer 11 includes anedge 18 with a predetermined length. Theedge 18 is downward folded and attached on a side of the water-tight layer 11 so as to form two water-tight layers. Thetooth rows 12 of zipper mechanism are sewn above the water-tight layer 11. - Referring to
FIG. 6 , the water-tight strips 10 have one water-tight layer 1. The water-tight layer 11 includes anedge 18 with a predetermined length. Theedge 18 is upward folded and attached on a side of the water-tight layer 11 so as to form two water-tight layers. Thetooth rows 12 of zipper mechanism are sewn above the water-tight layer 11. - Further referring to
FIG. 10 , eachtooth rows 12 of zipper mechanism is sewn above each water-tight layer 11 and water-tight layer 11 is elastic, and thus the elastic deformation of the water-tight layer 11 absorbs a part of pulling force when the water-tight layer 11 is laterally pulled by the pulling force. The rest of the pulling force will not directly affect theedge 18, and thus thestitches 111 of theedge 18 is not broken and then damaged by the stress formed by the pulling force. Accordingly, the capacity of thezipper 1 which resists the pulling force is increased. - Referring to
FIG. 7 , it depicts a water-tight and air-tight zipper 1 according to another embodiment of the prevent invention. Thezipper 1 includes two water-tight strips 10 (such as rubber strip, nylon strip, etc.). The water-tight strips 10 have one water-tight layer 11.

Each water-tight strip 10 is individually provided with twotooth rows 12 of zipper mechanism which are respectively sewn above and under the water-tight strip 10, whereby the water-tight layer 19 can seal the gap between thetooth rows 12 of the water-tight strip 10. Acore rope 121 is individually disposed in thetooth rows 12. Thetooth rows 12 have a plurality of continuously oval-shaped teeth 13 (or non-continuously oval-shapedteeth 13 orteeth 13 of non-continuous shape). There is a proper tooth distance betweenadjacent teeth 13. The twotooth rows 12 both pass through azipper pull 14 and are corresponding to each other, shown inFIG. 1 . A receivingspace 15 is formed in eachtooth 13, and eachtooth 13 includes a connectingportion 16 disposed at the front end thereof. The size of the receivingspace 15 is bigger than that of the corresponding connectingportion 16 of theteeth 13 of thetooth rows 12. The twotooth rows 12 are engaged with each other by pulling the zipper pull 14, thereby forcingedges 112 of the two water-tight strips 10 to be sealed. There is no gap formed between the edges of the two water-tight strips 10 because the two water-tight strips 10 are elastic, thereby being completely air-tight and water-tight. - Referring to

Atooth row 12 of zipper mechanism is individually sewn in the accommodating spaces of the water-tight strips 10.Stitches 111 pass through thegaps 171, such that eachtooth row 12 of zipper mechanism is sewn in each accommodating space. Then, thegaps 171 are sealed by heat, thereby preventing from the permeation of water. Acore rope 121 is individually disposed in thetooth rows 12. Thetooth rows 12 have a plurality of continuously oval-shaped teeth 13 (or non-continuously oval-shapedteeth 13 orteeth 13 of non-continuous shape). There is a proper distance betweenadjacent teeth 13. The twotooth rows 12 both pass through azipper pull 14 and are corresponding to each other, shown inFIG. 1 . A receivingspace 15 is formed in eachtooth 13, and eachtooth 13 includes a connectingportion 16 disposed at the front end thereof. The size of the receivingspace 15 is bigger than that of the corresponding connectingportion 16 of theteeth 13 of thetooth rows 12.
