Thus, a definition of "a first" or "a second" feature may explicitly or implicitly include one or more of the features, and in the description of the invention, "a number" or "a number" means two or more unless explicitly specified otherwise.

The utility model provides a water vapour sealed zipper, includes the baseband fabric, and the baseband fabric includes first meshbelt 1 and second meshbelt 2, and the inboard of first meshbelt 1 and second meshbelt 2 is provided with chain tooth 5, the outside of first meshbelt 1 and second meshbelt 2 all is provided with seal coat 3, seal coat 3 extends to the outside formation sealing strip of chain tooth 5, the sealing strip department of first meshbelt 1 is provided with sticiss sand grip 31, sticiss sand grip 31 towards second meshbelt 2 one side, sticis sand grip 31, sealing strip and 3 formula as an organic whole of seal coat.

In the invention, the first webbing 1 has the pressing protrusion 31, and the second webbing 2 has a plane surface facing the first webbing 1, but the second webbing 2 may have a groove 311 facing the pressing protrusion 31, but the depth of the groove 311 is less than the height of the pressing protrusion 31.

Also in the present invention, the side of the press rib 31 facing the second webbing 2 may have a groove 311.

Although fig. 1 and 2 show the first webbing 1 on the left and the second webbing 2 on the right in the present invention, they may be interchanged in practice, i.e. the pressing rib 31 may be provided on the left side of the sealing coating 3 or on the right side of the sealing coating 3.

The position of the dashed lines in fig. 1 of the present invention is used to indicate the compression ribs 31, which are actually integral with the adjoining sealing coating 3.

The sealing coating 3 is made of TPU or PVC, and has good ductility, elasticity and sealing performance.

In the embodiment, the sealing coating 3 is flush with the outer side of the zipper teeth 5 corresponding to the first woven tape 1, namely after the zipper is closed, the surface of the sealing coating 3 of the whole zipper is in a flat state, no additional protruding part exists, and the zipper puller can be smoothly pulled.

The surface of the pressing protruding strip 31 is preferably arc-shaped in this embodiment, when the first mesh belt 1 and the second mesh belt 2 are combined, the sealing coatings 3 of the two mesh belts are mutually extruded, and when the pressing protruding strip 31 is extruded, the pressing protruding strip 31 can be deformed, so that not only the sealing of the two mesh belts is maintained, but also the sealing coatings 3 can be prevented from protruding outwards.

In the preferred embodiment, the outer surface of the seal coating 3 is provided with the functional film 32, and the functional film 32 is added when the seal coating 3 is melted and is adhered to the surface of the seal coating 3 when the seal coating is cooled.

Namely, the functional film 32 in the present invention is directly stuck by the seal coating 3 without additional glue secondary processing.

In this embodiment, the functional film 32 is one or more of an acid and alkali resistant film, a reflective film, a smooth film, and a colored film.

The functional film 32 may be completely covered with the seal coat 3, partially covered with the seal coat, or linear or curved as required.

The fastener element 5 is preferably provided with a sealing convex pin 6, the sealing convex pin 6 comprises a head part 62 and a neck part 61, the neck part 61 penetrates through the inner side and the outer side of the fastener element 5, the head part 62 is arranged on one surface of the inner side of the fastener element 5, the neck part 61 is connected with the sealing coating 3, and the sealing convex pin 6 and the sealing coating 3 are integrally formed.

The sealing coating 3 and the sealing convex nails 6 are formed by melting the raw materials of the sealing coating 3 and then injecting the melted raw materials into the zipper for cooling at one time.

During production, the first woven belt 1 and the second woven belt 2 are connected together through the zipper teeth 5, namely the zipper teeth 5 on the first woven belt 1 and the second woven belt 2 are buckled, raw materials are melted, then the melted raw materials are injected between the zipper teeth 5 and coated on the surface of base belt fabric, meanwhile, the sealing coating 3 and the sealing convex nails 6 are formed, and the production can be finished after the raw materials are cooled and formed.

In the present invention, the sealing pin 6 does not go over the binding thread 4 where the fastener element 5 is fixed to the base fabric.

As shown in fig. 5, in the using process, the fastener element 5 on the second woven tape 2 will collide with the sealing stud 6 on the first woven tape 1, the same fastener element 5 on the first woven tape 1 will collide with the sealing stud 6 on the second woven tape 2, and the sealing coatings 3 of the first woven tape 1 and the second woven tape 2 at the outer side of the fastener element 5 also contact with each other, so that the whole zipper can realize sealing from the outer side surface of the base fabric to the inner side surface of the fastener element 5, when the zipper is bent inwards (the base fabric is at the outer side) or the base fabric is subjected to left and right pulling forces, a gap may occur between the sealing coatings 3 at the outer side of the fastener element 5, and at this time, the fastener element 5 can achieve good sealing through the tight contact of the fastener element 5 and the sealing stud 6.

In the present embodiment, it is preferable that the surface of the head portion 62 of the sealing pin 6 is flush with the highest surface of the inside of the fastener element 5, that is, the head portion 62 of the sealing pin 6 can fill the gap between two adjacent fastener elements 5, and at the same time, it does not protrude to the outside of the fastener element 5, which results in poor use of the slider.

In the preferred zipper of this embodiment, a plurality of zipper teeth 5 are arranged in sequence, a sealing convex pin 6 is arranged between two adjacent zipper teeth 5, and the heads 62 of two adjacent sealing convex pins 6 are connected into a whole.

As shown in fig. 6, the head portions 62 of the sealing studs 6 on all the first woven tapes 1 are connected into a whole, the head portions 62 of the sealing studs 6 on all the second woven tapes 2 are connected into a whole, and the portion connecting the head portions 62 of two adjacent sealing studs 6 is referred to as a tie bar 63, when the raw material is cooled and formed, the portion of the tie bar is contracted inwards, the tie bar 63 can prevent the head portions 62 from being contracted and transited, so that gaps are formed between the tie bar and the edges of the fastener elements 5, further, when the zipper is bent outwards (the fastener elements 5 are positioned at the outer sides), the distance between the fastener elements 5 at the bent positions is increased, and the tie bar 63 can pull and deform the head portions 62 at the bent positions, so that the head portions 62 can still fill the gaps between the fastener elements 5, and a good sealing effect is ensured.

In fig. 5, the broken line is used to distinguish the position of the seal coat layer 3 on the base fabric from the position outside the fastener element 5, and in fact the seal coat layer 3 is integrated at both positions.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
