Water-tight and air-tight zipper

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.

1 . A water-tight and air-tight zipper comprising two elastically water-tight strips, characterized in that: 
 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 mechanisms 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.

       3 . The water-tight and air-tight zipper according to  claim 2 , wherein the teeth are continuously oval-shaped teeth or non-continuously oval-shaped teeth.  
   
   
       4 . The water-tight and air-tight zipper according to  claim 2 , wherein the teeth are continuously rectangular teeth or non-continuously rectangular teeth.  
   
   
       5 . The water-tight and air-tight zipper according to  claim 2 , wherein the teeth are teeth of non-continuous shape.  
   
   
       6 . The water-tight and air-tight zipper according to  claim 1 , wherein the water-tight layers includes an edge with a predetermined length, the edge is folded and attached on a side of the water-tight layer so as to form two water-tight layers, and tooth rows of the zipper mechanism are sewn above the water-tight layer.  
   
   
       7 . A water-tight and air-tight zipper comprising two water-tight strips, characterized in that: 
 the water-tight strips have one water-tight layer, the water-tight layer is folded, and attached together, and another water-tight layer is disposed between the folded water-tight layer so as to form three water-tight layers, each water-tight strip is individually provided with a zipper mechanism sewn above and under the water-tight strip, and thus the water-tight layer seals the gap between the water-tight strip, 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.    
   
   
       8 . The water-tight and air-tight zipper according to  claim 7 , wherein each water-tight strip is individually provided with two tooth row of the zipper mechanism which are respectively sewn above and under the water-tight strip, a core rope is individually disposed in the tooth rows, the two tooth rows have a plurality of teeth, there is a proper tooth distance between adjacent teeth, the two tooth rows both pass through a zipper pull and are corresponding to each other, a receiving space is formed in each tooth, each tooth includes a connecting portion disposed at the front end thereof, and the size of the receiving space is bigger than that of the corresponding connecting portion of the teeth of the tooth rows.  
   
   
       9 . The water-tight and air-tight zipper according to  claim 8 , wherein the teeth are continuously oval-shaped teeth or non-continuously oval-shaped teeth.  
   
   
       10 . The water-tight and air-tight zipper according to  claim 8 , wherein the teeth are continuously rectangular teeth or non-continuously rectangular teeth.  
   
   
       11 . The water-tight and air-tight zipper according to  claim 8 , wherein the teeth are teeth of non-continuous shape.  
   
   
       12 . A water-tight and air-tight zipper comprising two water-tight strips being integrally formed therewith, characterized in that: 
 the water-tight strips includes a hollow main body, the main body has an accommodating space and two gaps respectively disposed upper and lower the accommodating space, a zipper mechanism is individually sewn in the accommodating spaces of the water-tight strips, stitches pass through the gaps such that each zipper mechanism is sewn in each accommodating space, and the gaps are sealed by heat, thereby preventing from the permeation of water, 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.    
   
   
       13 . The water-tight and air-tight zipper according to  claim 12 , wherein a tooth row of the zipper mechanism is individually sewn in the accommodating spaces of the water-tight strips, a core rope is individually disposed in the tooth rows, the two tooth rows have a plurality of teeth, there is a proper tooth distance between adjacent teeth, the two tooth rows both pass through a zipper pull and are corresponding to each other, a receiving space is formed in each tooth, each tooth includes a connecting portion disposed at the front end thereof, and the size of the receiving space is bigger than that of the corresponding connecting portion of the teeth of the tooth rows.  
   
   
       14 . The water-tight and air-tight zipper according to  claim 13 , wherein the teeth are continuously oval-shaped teeth or non-continuously oval-shaped teeth.  
   
   
       15 . A water-tight and air-tight zipper comprising two water-tight strips being integrally formed therewith, characterized in that: 
 the water-tight strips includes a hollow main body, the main body has an accommodating space and two grooves respectively disposed upper and lower the accommodating space, a tooth row of zipper mechanism is individually sewn in the accommodating spaces of the water-tight strips, stitches pass through the grooves such that each tooth row of zipper is sewn in each accommodating space, and the grooves are filled with water-tight material for sealing a gap therebetween, 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.
