Description

  The present invention relates to a maternity bra. More specifically, the present invention flexibly responds to a change in volume without giving a feeling of pressure to a bust before and after childbirth.

  During the pregnancy period from the beginning of pregnancy to childbirth, the volume of the bust increases with the development of the mammary gland, and it is known that the size of the brassiere cup is usually about 2 cups larger than before pregnancy. In addition, it is known that the volume of the bust changes after delivery and according to the progress of the lactation period.

  As a brassiere that can cope with the bust change before and after childbirth, the present applicant, as shown in FIG. 5, has three pieces of component members 2 made of a stretchable material whose stretch characteristic is the nipple direction (arrow direction in the figure). The left and right cup parts 5 are formed by stitching 3, 4, and a plurality of wire-like fine lines are aligned on the outer periphery of the core wire along the lower edge curved part 6 of the cup part 5 and spirally wound. Proposed wire bra 1 provided with a wire (not shown) is proposed (see Japanese Patent Publication No. 4-47041).

  The prenatal wire brassiere 1 has the stretch characteristics of the three pieces 2, 3 and 4 constituting the cup portion 5 in the nipple direction, so that the stretch characteristics appear radially starting from the nipple and the height of the bust It is possible to follow the bulging change in the direction.

Japanese Examined Patent Publication No. 4-47041

  The brassiere 1 of Patent Document 1 has the advantage that it can follow changes in the height direction of the bust, but the whole bust swells not only in the height direction of the bust but also in the bust base portion before and after childbirth. In some cases, the elasticity of only the nipple direction alone cannot cope with a significant change in the volume of the bust. In addition, since the sewn portions of the three component members 2, 3, and 4 and the wires are stretched and the expansion and contraction is easy to be suppressed, prepartum and breastfeeding without pressing the bust or underbust in any direction There is still room for improvement in terms of providing a comfortable fit over the entire period of the period. Furthermore, the prenatal wire bra 1 is not backed, and there is room for improvement in terms of bust stability and shape retention.

  The present invention has been made in view of the above problems, and flexibly follows changes in the volume of the bust during the lactation period before and after childbirth, so that a comfortable fit without pressing the bust or underbust in any direction It is an object of the present invention to provide a maternity brassiere that can protect a bust that is heavy and heavy, and that is excellent in shape retention of the bust.

In order to solve the above-mentioned problem, the present invention has a cup part having a two-layer structure of a front cup and a back cup,
The front cup is made of a fiber material having high elasticity in all directions of vertical and horizontal directions, and the back cup is also made of an elastic resin sheet having high elasticity in all directions of vertical and horizontal directions,
There is provided a maternity bra characterized in that the front upper edge of the front cup and the back cup are separated from each other without being sewn, and the side upper edge is sewn together.

As described above, the cup part has a two-layer structure of the front cup and the back cup, so that the bust that greatly bulges due to pregnancy and childbirth can be protected in a stable state, and the bust drooping can be prevented and retained. Can increase the sex.
In addition, the front cup constituting the cup part of the two-layer structure is formed from a fiber material having high elasticity in all directions of vertical and horizontal directions, and the back cup is also an elastic resin having high elasticity in all directions of vertical and horizontal directions By forming it from the sheet, it is possible to flexibly follow the significant volume change of the bust before and after breastfeeding without restraining the elongation even if the cup part has a two-layer structure, and the bust can be moved in any direction. It can also be set as the structure which does not press.
That is, with the above-described configuration, a comfortable fit can be imparted over the entire period of breastfeeding before and after childbirth without inhibiting the development of the mammary gland, and the stability and maintenance of the bust as described above. The shape can be maintained.

The materials constituting the front cup and the back cup both preferably have an elongation of 2 times or more in all longitudinal and horizontal oblique directions, and particularly have an elongation of 2 times or more and 3 times or less. It is preferable.
As described above, the elongation of the material constituting the front cup and the back cup is preferably 2 to 3 times in all directions. If the elongation in all directions is less than 2 times, While it may become impossible to follow changes in the volume of the bust during breastfeeding after childbirth, if the elongation in all directions exceeds three times, the bust stability is good, but the bust stability is good. It is because there is a possibility that the property may be impaired.

The fiber material used for the front cup is not particularly limited as long as it is a material having high stretchability in all directions as described above. For example, a stretch sheet using a spandex yarn, a two-way tricot, etc. These stretch knitted materials are preferably used.
Also, the elastic resin sheet used for the back cup is not particularly limited as long as it is a material having high elasticity in all directions as described above. For example, a sheet-like urethane foam or nonwoven fabric having good elasticity Alternatively, a thick sheet-like circular knitted material (cardboard knit) knitted from a highly elastic yarn such as polyurethane is preferably used.
Furthermore, the thickness of the back cup is preferably about 1.5 mm to 3 mm. The thickness of the back cup is preferably about 1.5 mm to 3 mm. If the thickness of the back cup is less than 1.5 mm, the protection, stability and shape retention of the bust are insufficient. On the other hand, if the thickness exceeds 3 mm, the repulsive force increases, and the followability to the volume change of the bust may be deteriorated.

In addition, as described above, the front cup and the back cup are structured such that the front upper edges are separated from each other without sewing, so that it is possible to avoid a decrease in stretchability due to sewing, and to more easily follow changes in the volume of the bust. can do.
In the portion where the front cup and the back cup are separated without being sewn as described above, the back cup that is in direct contact with the skin has a larger elongation than the front cup. Accordingly, the upper side of the front cup protrudes from the upper side of the front cup when worn so that the upper side of the front cup is positioned 0.3 cm to 1.5 cm, preferably about 0.5 cm to 1.0 cm above the upper side of the rear cup. It is preferable not to have it.

On the other hand, as described above, the upper side edges of the front and back cups are sewn together to support the bust on the side and provide a sense of stability.
The side upper edge of the front cup and the back cup is sewn, for example, by wrapping the side upper edge of the back cup with the cloth of the side upper edge of the front cup, and the side upper edge of the skin side in the wrapped state. In addition, by stretching and stretching the stretch tape that is continuous from the upper end edge of the back surface portion, good stretchability of the side upper end edge can be maintained without being deteriorated by sewing.

The lower peripheral edge of the front cup and the back cup is sewn with a base part made of the same elastic material as the front cup and an elastic tape without using a wire, and the base part is a front center cloth. And the side cloth is extended to form a back surface portion.
During breastfeeding before and after childbirth, the underbust is usually increased by about 5 cm as the bust volume changes, but the base part and the back part continuous to the base part should be formed from the same stretchable material as the front cup part. Therefore, it is possible to flexibly follow the change of the underbust and prevent the stomach from being compressed. In addition, since the lower peripheral edge and the base part of the front cup and the back cup are sewn without using a wire, it is easy to follow the shape change of the bust, and the position of the sewn part has shifted downward. Even in this case, since the wire does not press the underbust, a comfortable wearing feeling can be obtained.
Sewing between the lower peripheral edge of the front cup and the back cup and the base part is, for example, made elastic as the elastic tape at the seam allowance between the lower peripheral edge of the front cup and the back cup and the upper part of the base part. It is preferable to have a structure in which stretchability is given to the sewn portion by stacking bias tapes such as a tricot and sewing by double needle stitching.

  In this way, the cup part, the base part, and the back part are all stretchable in all directions, so they flexibly follow changes in bust and underbust during and after breastfeeding, and bust and underbust. A comfortable fit that does not compress the bust in any direction can be provided.

  Further, a highly elastic elastic member is sewn along the front upper edge on the outer side of the front cup to clean the edge portion, and the front upper edge of the back cup is edged by piping using the high elastic elastic member. The front cup and the back cup are composed of upper and lower cup parts, and the upper and lower joint parts of the front cup are sewn by laying or splitting the cup cloths together. The upper and lower joints are sewn via a highly stretchable elastic member with the elastic resin sheets cross-sectioned together, and there is an extension stop on the cup, including the front and back cups. It is preferable that the entire cup portion is configured to expand and contract in all directions without causing it to occur.

As described above, since the highly elastic elastic member is used for the end edge portion of the front upper edge of the front cup and the back cup, it is possible to prevent a decrease in stretchability due to the end edge portion.
As the highly stretchable elastic member along the front upper edge on the outer side of the front cup, for example, a stretchable woven or knitted member such as stretch tape or stretch lace having stretchability twice or more is used.
In addition, the highly elastic elastic member for piping used for the front upper edge of the back cup is made of a stretch tape having at least twice the elasticity, and a material used for the front cup, the base part, and the back part in a tape form. An elastic woven or knitted member such as one cut into two is used.

  In addition, as described above, the front cup and the back cup can be formed into a three-dimensional shape that makes it easy to fit the front and back cups to the bust by configuring the upper and lower cup parts. By positioning the nipple on the convex portion of the bust, it is possible to protect the bust in a stable state without pressing the developing nipple.

Further, as described above, the upper and lower cup parts of the upper and lower cup parts of the back cup are sewn via the highly elastic elastic member in a state in which the cross sections of the elastic resin sheets are brought together. It is possible to prevent a decrease in stretchability due to the sewing.
First, the upper and lower cup parts are sewn by matching the cross-sections of the lower end edge of the upper cup and the upper end edge of the lower cup made of a cut elastic resin sheet, and applying the highly elastic elastic member on the cross section. By performing sewing with stitches having elasticity such as bird stitching, the elasticity of the sewn portions of the upper and lower cups can be kept higher.
Examples of the highly stretchable elastic member used for the upper and lower joints of the back cup include a stretch tape having a stretchability of 2 times or more and a material used for the front cup cut into a tape shape. The elastic woven or knitted member is used.

  Further, as described above, it is preferable that the front cup is composed of the upper and lower cup portions similarly to the back cup, and the upper and lower cups are sewn together along a line passing through the nipple position. At this time, the joint part of the upper and lower cup parts is sewn with a stitch that gives stretchability, such as three-point zigzag stitching or flat two stitches, for example, as a one-side-down joint where the seam allowance of the upper and lower cup parts is tilted downward. It is preferable to wear, and the seam allowance of the upper and lower cup portions may be split up and down.

  In this way, since the entire cup part is expanded and contracted in all directions without the extension part existing in the cup part including the sewing part of the front and back cups, even for a significant volume change of the bust, It can be followed very flexibly and can be worn for a long period of time from the beginning of pregnancy to childbirth and even to the lactation period.

As described above, according to the present invention, the cup portion has a two-layer structure of the front cup and the back cup, so that the bust that bulges greatly due to pregnancy and childbirth can be protected in a stable state, and the bust It can prevent drooping and improve shape retention.
In addition, the front cup constituting the cup part of the two-layer structure is formed from a fiber material having high elasticity in all directions of vertical and horizontal directions, and the back cup is also an elastic resin having high elasticity in all directions of vertical and horizontal directions By forming it from the sheet, it is possible to flexibly follow the significant volume change of the bust before and after breastfeeding without restraining the elongation even if the cup part has a two-layer structure, and the bust can be moved in any direction. It can also be set as the structure which does not press.

In addition, as described above, the front cup and the back cup are structured such that the front upper edges are separated from each other without sewing, so that it is possible to avoid a decrease in stretchability due to sewing, and to more easily follow changes in the volume of the bust. can do.
On the other hand, the side upper end edges of the front cup and the back cup are sewn together to support the bust on the side and give a sense of stability.

In addition, as described above, by forming the base portion and the back portion continuous to the base portion from the same stretchable material as the front cup, the stomach can flexibly follow changes in the underbust accompanying the volume change of the bust. It is possible to prevent pressure on the part or the like.
Further, as described above, the lower peripheral edge and the base portion of the front cup and the back cup are sewn without using a wire, so that it is easy to follow the shape change of the bust and the position of the sewn portion is lower. Since the wire does not squeeze the underbust even when it is shifted to the side, a comfortable wearing feeling can be obtained.

  As described above, according to the present invention, the cup part, the base part, and the back part are all configured to be stretchable in all directions, so that it is possible to flexibly change the bust and underbust during the breast feeding period before and after childbirth. It is possible to follow and provide a comfortable fit that does not compress the bust or underbust in any direction.
