Description

The present invention relates to clothing having a cup portion.

2. Description of the Related Art Conventionally, in clothes having cup portions such as brassieres, those in which a wire is provided at the lower edge of the cup portion are widely used in order to adjust the shape of the bust and make the body line look beautiful. The rigidity of the wire is used to stop the deformation of the cup part and keep the shape of the bust beautiful. It is common to select one of the sizes that is relatively close to the wearer's size. Therefore, if there is a discrepancy between the size and shape of the wearer's individual bust and the size and shape of the wire used, the bust will be adjusted to the cup or wire side, but the wire shape will match the wearer's verge line. There is a problem that a feeling of oppression is caused if the weight does not match the weight. Therefore, various techniques have been proposed to make the wire less likely to bite into the body (see, for example, Patent Documents 1 to 3).

JP 2020-200556 A Utility Model Registration No. 3075543 JP-A-7-300703

According to these technologies, it is possible to adjust the shape of the wearer's body beautifully without feeling uncomfortable with the wire, and to make it comfortable to wear by deforming and retaining the shape so that it fits the body. is. For example, in Patent Document 1, as a resin wire attached to the cup portion, the central lower bottom portion is a first polyurethane-based shape-memory resin having a property of deforming from a shape-memory shape at a temperature lower than the body temperature of the human body. and the body center side upright part and the armpit side upright part are formed of a second polyurethane-based shape memory resin that has the property of maintaining the shape in memory at a temperature lower than the temperature exceeding the temperature of the human body. proposed a resin wire for the cup portion that is deformable so as to conform to the wearer's body. Patent Literature 2 proposes a cup wire that allows plastic deformation in a direction that matches the body shape of the wearer by reducing the elasticity of both ends by heat treatment. In Patent Document 3, by providing an amorphous resin sheet-like piece extending in a plane along the edge of the cup, the stress generated by the wire can be dispersed in a plane and the wearing feeling can be improved. clothing is suggested. However, in these techniques, there is a problem that if the formability is emphasized, the wearing feeling is not sufficient, and if the wearing feeling is emphasized, the formability is not sufficient.

The present invention adapts to individual differences in the wearer's body shape, which can suppress problems such as the occurrence of gaps between the clothing and the body and the body getting caught in the body, even when using an existing general shape-retaining member such as a wire. It is an object of the present invention to provide a garment having a corresponding cup portion with a high size fitting rate.

In order to achieve the above object, the clothing having the cup portion of the present invention is
comprising a pair of cup portions, a front central member, and a back portion;
The front center member is provided on the front center side of the pair of cup portions and connects the pair of cup portions,
The back portion is provided on the side of the cup portion,
The cup portion has a cup shape along the verge's line, and a shape-retaining member is provided at the lower edge of the cup shape,
The ends of the pair of shape-retaining members on the front center side are fixed so as to maintain a constant distance,
The front center member has the following properties (1) to (4) in an extension recovery test in at least one direction,
The side end point on the cup cut of the front center member bisects the angle formed by a horizontal line passing through the bust top point and extending toward the front center side and a line passing through the bust top point and the lowest point of the cup cut. It is characterized by being between the intersection of the line on the side of the lowest point of the cup cut and the cup cut among the lines and the lowest point of the cup cut.

The clothing having the cup portion of the present invention is preferably a brassiere.

A clothing having a cup portion of the present invention will be described with an example. However, the present invention is not limited or restricted to the following examples. It should be noted that the drawings referred to below are schematically described, and the dimensional ratios of the objects drawn in the drawings may differ from the dimensional ratios of the actual objects. The dimensional ratios of objects and the like may differ between drawings.

(First embodiment)
FIG. 1 shows a brassiere 100 according to a first embodiment, which is an example of clothing having cup portions of the present invention. FIG. 1 is a perspective view of a brassiere 100 of this embodiment. In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals.

A brassiere 100 of this embodiment is a brassiere comprising a pair of cup portions 101 , a front central member 102 , a pair of back portions 103 and a pair of shoulder straps 104 . The front center member 102 is provided on the front center side of the pair of cup portions 101 and connects the left and right cup portions 101 . One ends of a pair of back portions 103 are attached to the sides of the left and right cup portions 101 . A connecting locking portion (not shown) is attached to the other end of the pair of back portions 103 so that it can be attached and detached near the center of the back. Each cup portion 101 has a cup cut C shaped along the verges line. A shape-retaining member 105 such as a wire is provided at the lower edge of the cup rim C. As shown in FIG. The ends on the front center side of the shape retaining members 105 provided on the left and right cup portions 101 are fixed so as to keep a constant distance therebetween.

The front center member 102 has the following characteristics (1) to (4) in at least one direction.
(1) The difference in elongation between the forward and return passes under a load of 200 g is 1.5 times or more the difference in elongation between the forward and return passes under a load of 400 g.
(2) The return elongation recovery rate is 10% or less with a load of 400 g and 20% or less with a load of 200 g.
(3) The elongation recovery rate at 0 g load on the return path is 70% or more.
(4) Elongation at 600g load is 100% or less.

The above characteristic values are the values obtained by the elongation recovery test by the following measurement method. Materials having the characteristics of (1) to (4) linearly expand when a load is applied, but the load is slightly removed. It has the characteristic that it is difficult to return, and that it returns when the load is completely removed.

Conventional wired brassieres use a material that does not stretch in the front center part, emphasizing shapeability. However, if the front center portion is not elongated, it is impossible to accommodate individual differences in the front center shape, and it is difficult to match the wire shape with the Verges shape. If the wire shape and Burgess shape do not match, the lower point of the wire will be below the bust, and the upper side of the cup will hit the bust, the cup (brassie) will slide down, the presence of the wire will be easily felt, and the cup will not fit. Problems such as tilting and digging in the upper side and lifting the side occur. Also, if the wire doesn't fit the verges line, it's easy to feel the pressure.

The front center member used in the present invention is a material that stretches where it stretches but does not stretch where it does not stretch, so it deforms according to the shape of the body. You can apply enough force to deform it. That is, the wire shape can be transformed into a Verges shape, and the shape can be maintained and stabilized (absorbing individual differences in front center). By deforming the shape of the front center and responding to individual differences, it is possible to match the wire shape to the shape of Verges, making it easier to put in the bust and increase the size matching ratio of wire brassieres. By deforming only the necessary part, it is possible to absorb, for example, the difference in the size of the left and right bust without causing problems in other parts. In addition, it is possible to respond to changes in bust size due to individual physical conditions.

If the area of the front center member 102 is too narrow, it will not be able to exhibit sufficient size adaptability, and if it is too wide, deformation will increase, which may affect bust sculptability. Therefore, the side end point of the front center member 102 on the cup cut C must be in a predetermined area. FIG. 2 is a diagram for explaining parts of a garment having a cup portion of the present invention. As shown in FIG. 2, the region divides the angle formed by a horizontal line passing through the bust top point T and extending toward the center of the front and a line passing through the bust top point T and the lowest point U of the cup opening C into three equal parts. This is the area between the intersection point X between the line L1 on the side of the lowest point U of the cup opening C and the cup opening C, and the lowest point U of the cup opening C, among the lines L1 and L2. By matching the wire shape and the vergis shape in this region, it becomes easier to match the other portions. If the base portion is provided below the cup opening C and the side portion of the front center member 102 has a width, the position of the end point on the lower side of the base portion is the vertical direction of the side end point on the cup opening C. It does not have to be on the lower side, and it can be shifted to the front center side or side side.

<Characteristics measurement method of the front center member>
In the measurement of the properties in the present invention, since the measurement is different from the elongation recovery test specified in JIS etc., the measurement method will be shown below. In this evaluation, a sample piece with a width of 2.5 cm and a grip interval of 5.0 cm was used, but if the size of the sample piece to be measured is insufficient, it can be evaluated by conversion. It is possible. Measurement is performed in an environment set at a temperature of 35°C and a humidity of 65%. Samples are taken so that the width is 2.5 cm and the grip spacing is 5.0 cm. A sample is attached to a water absorption Byrek method test device with a clip, pulled with a load of 200 g, and the sample length after 1 minute is measured (sample length at 200 g load on the outward trip). Next, a load of 200 g is added to make a total load of 400 g, and the sample length after 1 minute is measured (sample length at forward 400 g load). Furthermore, a load of 200 g is added to make a total load of 600 g, and the sample length is measured after 1 minute (sample length at 600 g load). Next, the load of 200 g is removed and a total load of 400 g is applied, and the sample length after 1 minute is measured (sample length at return 400 g load). Furthermore, the load of 200 g is removed and the total load is set to 200 g, and the sample length is measured after 1 minute (sample length at return 200 g load). Finally, the load of 200 g is removed and the load is set to 0 g, and the sample length after 1 minute is measured (sample length at return 0 g load).

The above reciprocation of 0 g to 600 g to 0 g was repeated three times, and from the measured value of each sample length obtained at the third time, the difference in elongation between the forward and return passes at a load of 200 g, the difference in elongation between the forward and return passes at a load of 400 g. The difference, the elongation recovery rate at 400 g load and 200 g load on the return trip, the elongation recovery rate at 0 g load on the return trip, and the elongation rate at 600 g load are obtained.

Fig. 1 shows the results of comparison between various general materials used for the front center portion of clothing having a cup portion and materials having the above characteristics (1) to (4). The materials used are as shown in Table 1.

For Samples 1 and 3, as a deformable resin sheet, "Absotomer" (registered trademark) manufactured by Mitsui Chemicals, Inc. was processed into a mesh sheet, and a laminated fabric was applied to the front and back surfaces of the resin sheet. The smooth of sample 4 is arranged as . Samples 1 and 3 are obtained by laminating a resin sheet and a laminated fabric. No adhesive is used to bond the resin sheet and the laminate material, and the surface of the resin sheet is melted and adhered to the laminate material by thermocompression bonding. was made by changing As sample 2, "FINEX" (registered trademark) was used.

FIG. 3 shows the results of plotting the measured values for each sample length obtained in the third stretch recovery test. Table 2 shows the characteristics obtained for each sample.

Samples 1 and 3 gradually elongated when the load was increased, and even if the load was removed from 600 g, there was almost no force to return up to 200 g (stress relaxation). I know there is. It can be seen that Samples 2 and 5 stretch well and the force to return is almost the same as the force to stretch. Sample 4 stretches well, but the stretch is almost constant above a load of around 400 g, and it is considered that the stretch is already stretched near that point. When Samples 1 and 3 are used as the front center member, the front center side of the wire is deformed, the wire follows the vergis, the front center part does not wrinkle, and a garment that conforms to the body and has good fitting properties is obtained. . On the other hand, materials that stretch at the same ratio (Samples 2, 5, and 4) will stretch not only the necessary parts but also the parts that you don't want to stretch. can occur.

The front central member 102 preferably includes a deformable resin sheet, and fabric is arranged on at least one of the front surface and the back surface of the resin sheet. As the deformable resin sheet, for example, a temperature-sensitive flexible resin sheet (“absotomomer”) or the like can be used. It is also preferable that the resin sheet is foamed or formed into a mesh to adjust the elongation.

The temperature-sensitive flexible resin sheet is preferably a sheet made of shape memory resin. The shape memory resin is selected from a group of shape memory resins consisting of norbornene, transpolyisoprene, styrene-butadiene copolymer, urethane, ester, styrene, olefin, lactic acid, acrylic, and amide. A structure containing one or more of these can be used.

When the resin sheet is a temperature-sensitive flexible resin sheet, its thickness is preferably in the range of 0.1 mm or more and 3.0 mm or less. If the thickness is less than 0.1 mm, the physical properties of the fabric placed on at least one of the front surface and the back surface have a greater effect, and the performance of the temperature-sensitive flexible resin sheet may not be exhibited. If the thickness is more than 3.0 mm, sewing becomes difficult and design restrictions may arise.

In the present invention, the front center member 102 has a specific range of stretch recovery properties in at least one direction, so that a garment having a cup portion with a high size fitting ratio can be obtained. Note that it is not essential that the front central member 102 deforms in all directions. If the front center member 102 has the above-described characteristics particularly in the circumferential direction when worn, the shape-retaining member on the front center side can be deformed and the state along the bust can be maintained.

The fabric arranged on at least one of the front surface and the back surface of the resin sheet includes knitted fabrics having a weft knitting structure such as cotton sheeting, milling, smooth and double knit, knitted fabrics having a warp knitting structure such as tricot and raschel, nonwoven fabrics (fiber can be preferably used. The material of the cloth can be selected according to the application. By selecting the above fabric, it is possible to improve the design of the front central member, in addition to improving the touch feeling, imparting cooling sensation and sweat absorption. Also, if different fabrics are used for the front side and the back side of the resin sheet, for example, the front side can be designed, and the back side can be sweat-absorbent or touched.

The fabric and the resin sheet can be bonded together using an adhesive or the like, but the resin on the surface of the sheet can also be heated and melted to adhere to the fabric.

It is preferable that the front central member of the present invention including the resin sheet and the fabric has a thickness in the range of 0.2 mm or more and 4.0 mm or less.

In the present embodiment, a generally used metal wire is used as the shape-retaining member 105, but the shape-retaining member 105 is not limited to this, and a resin wire or the like can also be used. It is also possible to insert a shape-retaining member corresponding to a wire into the integrally molded cup portion. Alternatively, the shape-retaining member may be formed by providing a portion that is hardened by increasing the compressibility during molding. The ends on the front center side of the shape retaining members 105 provided on the left and right cup portions 101 are fixed so as to keep a constant distance therebetween. Since the shape-retaining member is fastened at the upper end of the front center, the shape-retaining member can be deformed using this portion as a fulcrum. In order to fix the ends so as to keep a certain distance from each other, the ends of the shape-retaining member may be directly fixed to each other, or may be fixed with a separate member such as a non-stretchable or difficult-to-stretch fabric. .

[Evaluation Test 1] Stretch Shape Comparison of Front Center Member FIG. 4A is a schematic diagram showing the stretch of the front center member in a brassiere, which is clothing having a cup portion of the present invention. FIG. 4(B) is a schematic diagram showing elongation when a non-stretchable material (patterned marquise) is used as a central front member in a brassiere. Each figure shows the result of drawing a lattice on each front central member so that the elongation can be seen, wearing a brassiere on a body for evaluation, and observing the shape change of the lattice. As shown in FIG. 4(A), in the brassiere of the present invention, the lattice of the fabric of the front center member is distorted, and the wire shape of the front center is deformed (opened) to fit the Verges. Understand. On the other hand, in FIG. 4B, it can be seen that the lattice of the fabric is not distorted and the wire at the front center is maintained in a substantially wire shape even when worn.

[Evaluation Test 2] Wearing Evaluation FIG. 5 is a diagram showing evaluation of positions when the same wearer wore three types of brassieres. In (A) of FIG. 5, a brassiere, which is a garment having a cup portion of the present invention, is shown in (B). )), and (C) shows a state in which a brassiere in which a non-stretchable material (patterned marquisette) is used in the central front portion.

Each figure in FIG. 5 is provided with a reference line in order to make it easier to see where the brassiere is worn. The reference line was a triangle connecting three points, ie, the wire front center side endpoint, the wire side endpoint, and the lowest point of the barges. This wearer has a larger bust on the left side. In such a case, conventionally, if the size is matched to the smaller bust, the larger side does not fit and does not fit, so it is easy to be underlined.

In the brassiere (A), which is the garment having the cup portion of the present invention, the front center member absorbs the left-right difference of the burgis, so that the cups are evenly attached to the left and right. The front center member is deformed, the wire follows a shape close to the verge's line of the nude, and the wire end points widen, so that the cup fits the bust well (the cup is attached without tilting). Even on the left side where the bust is large, the wire is along the verges line, and there is a slight difference in the way the cups are attached. Bust sculpting power is good. It can be seen that in the brassiere (A), the wire on the left side is open, and the shape of the wire changes according to the left and right busts.

In the brassiere (B), which uses a stretchable material in the center front part, the fabric in the center front part is deformed, but the wire end points do not spread, so the wire does not follow the verges line of the large left bust, and the left cup is stretched. It becomes a tilted subscript, and there is a difference in the way the cup is attached to the left and right. In addition, the lower part and the extension of the front center part reduced the shaping power of the bust.

In the brassiere (C), which uses a non-stretchable material in the front center part, the cloth in the front center part does not deform and the wire end points do not spread, so the wires do not follow the verges line on the left and right bust, and the left and right The cup of the bust became the bottom, and the brassiere itself became the bottom, which reduced the shaping power of the bust.

As described above, it can be seen that the clothing having the cup portion of the present invention can provide a tailor-made fit that accommodates left-right differences and the like while ensuring the formability of the bust. By making the physical properties of the front center member specific, it is possible to absorb slight differences in left and right bust sizes and individual differences such as the distance between the left and right busts. Also, it is possible to use an existing cup or the like. Unlike the conventional idea of fitting the bust to a hard cup, this is to fit the brassiere (wire) to the shape of the bust, and the physical properties of the front center member can be used instead of the overall design. This is due to the discovery of

As described above, the present invention has been described with reference to a brassiere as a specific example of the embodiment. is possible. For example, the present invention can be applied to body suits, bra camisoles, bra slips, separate type swimwear tops, leotards, and other types of clothing having cup portions, in addition to the clothing of the above embodiments. It can also be suitably used for maternity clothes.

Various aspects are possible for the clothing having the cup portion of the present invention. For example, it can be applied to various types of clothing having a cup portion, such as sports clothing, outerwear, etc., in addition to foundation clothing.
