[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a snap fastener with a tape.
[0002]
[Prior art]
The applicant has developed and applied for the following snap fastener with tape.
(1) JP-A-10-33210 (2) JP-A-10-33211 (3) JP-A-2000-270906
(4) JP-A-2001-8711

(10) JP-A-2002-125720
[0003]
The snap fastener with tape according to the above (1) to (10) includes a male tape having a male engaging member and a female tape having a female engaging member. In each of the tapes, a plurality of male engaging members are attached, but one type, and a plurality of female engaging members are attached, but one type. Therefore, as for one tape, engagement members of the same shape are arranged in order.
[0004]
[Problems to be solved by the invention]
Although not a major inconvenience, it is not interesting in terms of design with one type of engaging member. In particular, baby clothes and the like want gorgeousness and color, but they are not enough.
[0005]
Further, when this fastener is used for an opening / closing portion stopper such as a shirt, the fastening member (button) has the same shape, so that the fastener may be crossed. The same goes for sighted people, especially for visually impaired people.
[0006]
In the present invention, at least two types of engagement members (buttons) provided on one fastener tape and at least two types of engagement portions when necessary are required, thereby solving the above problem. The purpose is to solve.
[0007]
[Means for Solving the Problems]
The fastener with a tape of the present invention is a tape in which a plurality of synthetic resin engaging members are formed and fixed on a cloth tape at predetermined intervals, and each engaging member of each tape comprises a base and an engaging portion. Each tape has at least two types of base shapes.
[0008]
DESCRIPTION OF THE PREFERRED EMBODIMENTS
The tape having at least two types of bases is preferably both a male tape having a male engaging member and a female tape having a female engaging member, but either one may be used. In the latter case, the remaining one will have only one type of shape, as in the prior art.
[0009]
The engaging portion of the engaging member may be any. It will usually consist of a male engaging projection and a female receiving portion. For each of the shapes, the above-mentioned prior arts (1) to (10) disclose various modifications.
[0010]
The present invention is characterized in that there are two or more types of bases in the engagement member. The shape may be a combination of polygons such as a triangle, a quadrangle, and a pentagon, a circle, an ellipse, a star, a petal, an irregular shape, and the like, and any combination may be used. In view of the object of the present invention, it is preferable that two or more shapes of each base are arranged so that those having the same shape are not continuous.
[0011]
Preferably, the engaging portions of both the male tape and the female tape forming a pair have two or more types of base shapes, and those having different base shapes have different sizes or structures of the engaging portions. . As a result, the male and female engaging portions can be engaged only when the shapes of the bases are the same. By doing so, anyone can understand that the engaging members having the same shape can be engaged with each other. Even infants and persons with intellectual disabilities can often recognize identity, and even visually impaired persons can find out by touching.
[0012]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0013]
<First embodiment>
FIG. 1 is a plan view of a fastener 1 with a tape according to a first embodiment of the present invention, as viewed from the joining surface side. FIG. 1A shows a female tape 5 having a female engaging member 4, and FIG. A male tape 3 having an engagement member 2. The opposite side of each member is not shown, but also has substantially the same appearance.
[0014]
FIG. 2A is a plan view of the male side engaging member 2, and FIG. 2B is a sectional view. An engagement projection 22 stands upright from the base 21 with the fabric tape 3 scissors. The engaging projection 22 has a central concave portion 24 and a bulging edge 23 for engagement around a distal end portion.
[0015]
The shape of the base 21 is a triangle in FIG. However, when viewed as a single cloth tape as shown in FIG. 1, the shape of the base 21 varies. In FIG. 1, a triangle, a star, a square, and a triangle are shown from the top.
[0016]
To mold the male member 2, a cloth tape 3 having a roughness through which molten resin passes and penetrates by molding pressure is disposed between an upper and lower mold (not shown) having a fastener molding space. The cloth tape in the hole 24 located inside the projection 22 is sandwiched and fixed between the upper and lower molds, and then, the synthetic resin is injected into the molding space. In order to prevent the tape 3 from being twisted by the injection pressure during the injection molding, several pins (not shown) are provided on the upper and lower molds forming the peripheral portion of the base 21 to hold down the tape 3. Therefore, a hole 25 having a complementary shape of the pin is formed in the base.
[0017]
In this way, the front side and the back side of the male member formed on both sides of the cloth tape 3 are integrated by the synthetic resin that penetrates the cloth tape 3. The tape cloth 3 needs to be a cloth through which a molten resin passes without being melted, and may be a woven cloth or a knitted cloth. For example, a cotton cloth, a blended cloth, or the like can be used. As the synthetic resin, a thermoplastic resin, for example, a polyacetal molten resin can be used.
[0018]
FIG. 3A is a plan view of the female-side engaging member 4, and FIG. 3B is a cross-sectional view. An engagement recess 42 is formed in a base 41 in a state where the fabric tape 5 is scissors. The engagement recess 42 has an engagement edge 43 inside the opening.
[0019]
The shape of the base 41 is a triangle in FIG. However, when viewed as a single cloth tape as shown in FIG. 1, the shape of the base 41 is various. In FIG. 1, a triangle, a star, a square, and a triangle are shown from the top.
[0020]
Since the method of molding the female member is substantially the same as that of the male member 6, detailed description will be omitted.
[0021]
FIG. 4 shows a cross section in a state where the male side engaging member 2 and the female side engaging member 4 are engaged.
[0022]
<Second embodiment>
Since the second embodiment is not substantially different from the first embodiment in the drawing due to drawing restrictions, the second embodiment will be described with the same drawings and the same reference numerals as those in the first embodiment. The second embodiment differs from the first embodiment in the following points. The points not particularly pointed out are the same as in the first embodiment.
[0023]
With respect to the male tape 3, not only the plurality of shapes of the base 21 of the engaging member 2 are provided, but also a plurality of engaging protrusions 22 having different sizes or structures are prepared. In the case of the base 21 having a specific shape, the engaging projection 22 having a specific size or structure is always obtained.
[0024]
Regarding the female side tape 5, not only the plurality of shapes of the base 41 of the engaging member 4 but also the plurality of engaging recesses 42 having different sizes or structures are prepared. In the case of the base 41 having a specific shape, the engagement recess 42 of a specific size or structure is always obtained.
[0025]
Further, only when the shapes of the bases 21 and 41 of the male and female engaging members 2 and 4 are the same (for example, a triangle shown in FIGS. 2 and 3), the engaging portions 22 and 42 coincide with each other. 5 are engageable. In other cases (for example, a triangle and a star), the engaging portions do not match and cannot be engaged.
[0026]
【The invention's effect】
According to the present invention, a button having two or more types of shapes can be obtained, so that a visually gorgeous impression is given. Therefore, it is particularly suitable as baby clothes.
[0027]
Further, according to the present invention, there is obtained an effect that there is no mistake in crossing buttons. This is because it is often possible for an infant or an intellectually disabled person to select the engagement members having the same shape, and even a visually impaired person can know by touching the hand.
[0028]
Further, in the case of the second embodiment, the engaging portions match only when the base shape is the same, and the male and female tapes can be engaged. A special effect is obtained in that there is no misunderstanding.
