Generally, there is a packing material as a method for the purpose of sealing, but it has a drawback that it requires a separate fastener such as a screw, a screw, an adhesive or the like at the time of attachment, and that the usage is limited.

[Problems to be solved by the invention] Since surface fasteners are detachable and easy to install, they are widely used for clothing such as rainwear and wet suits, and for industrial goods such as container building materials, but air or water etc. When it is used for the purpose of sealing the seal, there is a gap between the engaging element (hook) and the element to be engaged (loop), which has good air permeability, and the air or water leaks from that part. Had.

As a solution to such a problem, there is a structure in which a surface fastener is attached separately on both sides of the closed portion to reinforce the connection of the closed portion. And that
When engaging after mounting, the surface fastener can be engaged and there is no problem in some displacement, but the member having a sealing function has a problem that the sealing effect is lost even if there is some displacement.

Therefore, a surface fastener having a more complete airtightness, liquidtightness, and water blocking effect is desired.

[Means for Solving the Problems] The present invention is a surface fastener that has an airtight, liquid-tight, and water-stop effect in which a member having a sealing function is provided on the surface fastener itself in order to solve the above problems.

That is, the present invention relates to a member for closing a gap between two surface fasteners when at least one of the two surface fasteners engaged with each other is engaged with the surface fasteners over the entire length in the length direction or the width direction. A surface fastener for sealing that is provided with.

In the surface fastener of the present invention, the portion or position where the gap closing member (hereinafter, may be referred to as a closing member) is provided is particularly long when the length or width of the surface fastener is extended in one direction. There is no limit. When a closing member is provided on the surface of the surface fastener that has the engaging element or the engaged element, the closing member is fixed to the base surface of the surface fastener, and if there is an engaging element or an engaged element, the gap is closed. Since it cannot be completed completely, it is desirable that there is no engaging element or engaged element at the portion where the closing member is provided, and it is desirable to remove those elements by an appropriate method such as ultrasonic welding. Further, a closing member may be provided on the ear portion of the surface fastener having no engaging element or the like.

The closing member used in the present invention may be any one as long as it can close the gap between the two surface fasteners generated when the two surface fasteners are engaged. The material used for the closing member is preferably flexible plastic, self-adhesive plastic, water absorbent resin, foam or the like. Although various types of structures are used for the closing member, a ridge-like member, a ridge-like member having a structure in which an end face thereof is unevenly fitted,
There are those having a suction member with an arcuate cross section, and those having an end face coated with an adhesive.

Depending on its structure, the closing member can be provided on only one surface of the two engaging surface fasteners or on two surfaces thereof. In the structure provided on one surface, the portion of the other surface fastener contacting the closing member must be a flat surface without an engaging element or the like.

In order to obtain an airtight, liquidtight or watertight effect, the closing member should extend over substantially the entire length or width of the surface fastener.
It may be provided in parallel or obliquely in the length direction or the width direction.

Hereinafter, the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an example of a surface fastener according to the present invention, which has a structure in which a closing member 4 is provided in the center of the surface fastener 1 in the longitudinal direction, and a hook or the like is provided on the right side of the closing member 4. If the engaging element 2 and the engaged element 3 such as a loop are provided on the left side, there is only one type of surface fastener having such a structure. The coupling element and the engaged element engage with each other to function as a surface fastener.
FIG. 2 is a view showing the engaged state of the surface fastener of FIG. 1 in a cross section taken along the line AA. If the height of the closing member 4 is made equal to, or slightly higher or lower than the height of the engaging element, it is advantageous for the closing members 4 provided on the two surface fasteners to join and completely close the gap. is there. Further, when the closing member is made of a water-absorbent resin, it is desirable to design the closing member in consideration of the degree of swelling so that the swollen closing member does not become very large.

In addition to the structure in which the engaging element and the engaged element are provided on one surface as shown in FIG. 1, the present invention is applied to a surface fastener having only an engaging element and a surface fastener having only an engaged element like a normal surface fastener. It is also possible to provide a closing member.

FIG. 3 is a perspective view showing a structure in which two closing members 4, 4'are provided on the ears of the surface fastener 1, and FIG. 4 is an engaging element 2 having the closing member shown in FIG. It is a figure which shows the state which engaged the surface fastener 2 surface which has the compound element 3 separately by the cross section in a BB line.

5 and 6 are sectional views showing another example of the closing member according to the present invention, and FIG. 5 shows that the closing members 4, 4'are provided on the base surface of the surface fastener 1. It has a structure in which concave and convex members 5 and 6 to be fitted respectively are provided on the end faces of 4 and 4 '. FIG. 6 shows a structure in which the end surface of the closing member 4 has an adsorbing portion 7 having an arcuate cross section, and the end surface 8 of another closing member 4 ′ is used as a joint surface of the adsorbing portion 7. In this structure, the suction portion 7 is formed of a flexible plastic, and the suction portion is brought into close contact with the end surface 8 by pressing it against the joining end surface 8 to strengthen the sealing by the closing member 4, 4 '. You can Various structures can be used for the closing member according to other purposes.

In the present invention, since the engaging force of the surface fastener can be used also as the force for bringing the closing member into close contact, the engaging force of the closing member can be weakened, the weight can be reduced, and the attachment / detachment can be easily performed. There is.

The surface fastener used in the contact surface fastener of the present invention is used in combination with the engaging element and the engaged element, but is not particularly limited as long as it has an engaging function.
