Description

The present invention relates to a brassiere that can adjust the position and size of the left and right breasts, and can accommodate these changes.

Differences in the position and size of the breasts may occur for a variety of reasons. In response to this, brassieres have been proposed that aim to eliminate physical problems caused by left-right differences in breasts and to eliminate left-right differences in appearance.

For example, Patent Document 1 discloses a brassiere in which a pad is fixed to one of the left and right cups to compensate for the difference in breast size. In the brassiere of Patent Document 1, the pad has a shape that extends from halfway along the edge along the verge line of the breast to the upper end of the side edge of the cup portion. In the brassiere of Patent Document 1, since the pad is fixed, the effort required to attach the pad is reduced. On the other hand, it does not take account of changes in bust size or position.

Patent Document 2 discloses a brassiere equipped with a pocket for inserting a pad for correcting the difference in size between the left and right breasts, in which a pocket is formed between a cup body and an inner skin material, and a pocket is formed in the inner skin material. It is disclosed that an opening communicating with the pocket is formed, and the edges of the opening overlap each other so that the opening of the pocket has a lid. Further, Patent Document 2 discloses that a knit material with a moisturizing function is used as the inner skin material to provide more comfortable wear.

On the other hand, Patent Document 3 discloses a foundation in which the periphery of the cup is made of stretchable fabric as a foundation that fits the body and can function as a foundation even if there is a difference between the left and right breasts. . In the foundation of Patent Document 3, a stretchable fabric with the same shape as the backside and a bust cup sewn on is superimposed on the back side of a close-fitting part that forms a semicircular part where a bust cup is arranged, and the side edges of the stretchable fabric and The lower edge is sewn to the contact part, and the front center of the bust cup is sewn to the contact part together with the elastic fabric.

Furthermore, a brassiere is known in which a wire can be inserted or removed depending on the feeling of pressure or physical condition. For example, in Patent Document 4, a wire-attaching tube cloth is provided on the back side of the cup portion of a brassiere, and a wire is inserted therein, and at least one end of the wire-attaching tube cloth is used as a wire removal port, and the wire is removed. It is disclosed that the wire can be put in and taken out from the mouth. In the brassiere of Patent Document 4, the wire can be inserted and removed, and a wire prevention member is provided inside the sleeve cloth at the removal opening, and the wire is further reinforced by a fixing reinforcing material, so that the wire is prevented from coming off.

Further, Patent Document 5 discloses an invention of a brassiere that can adjust the position and size difference between the left and right breasts and accommodate these changes. The bra of Patent Document 5 has an underside adjustment pocket and a volume adjustment pocket on the back side of the cup part, and the base part of the bra has a front side base with an elastic skin-side base part and a wire insertion part on the surface. It has a structure in which parts are overlapped.

One of the cases in which the above-mentioned brassiere is used is when breast reconstruction is performed after mastectomy in the treatment of breast cancer or the like. Breast reconstruction includes methods that use implants and methods that use autologous tissue transplantation, but in either case, the breast is not always in a constant state after undergoing breast reconstruction.

The breast on the operated side changes over time depending on the postoperative course and physical condition. Furthermore, in the treatment of breast cancer, etc., weight gain or loss is often unavoidable due to the effects of medication, and the breast on the healthy side may also change in response to the weight gain or loss. In this way, there are differences between the left and right breasts, and these differences often change over time. The difference between the left and right breasts is reflected not only in the volume and shape of the breast, but also in the under position, so when adjusting the difference between the left and right breasts with a bra, it is important to be able to adjust not only the volume and shape but also the under position (vertical difference). desired.

In addition to individual breast changes, the size and shape of breasts also vary greatly from person to person, so even if you have large breasts or one breast is particularly swollen, it will not cause excessive pressure. What is desired is a bra that protects the breasts and allows adjustment of left and right differences.

In view of these circumstances, the present invention is capable of adjusting the under position of the left and right breasts, responding to changes in left and right differences over time, and that fits people of various body shapes without causing a feeling of pressure. An object of the present invention is to provide a bra that can maintain symmetrical breasts for a long period of time.

In order to solve the above-mentioned problems, the inventors have made repeated studies, and have developed a skin-side base in which the base of the bra includes a front base with a wire insertion part, a cup, and a stretchable material around the cup. and further includes an elastic member (e.g., elastic lace) extending from between the skin-side base part and the front-side base part and covering the surface of the skin-side base part and the surface of the cup part. By doing so, we discovered that it is possible to adjust the under position of the left and right breasts and respond to changes in the difference between the left and right breasts over time, and also to support breasts with large volumes, resulting in a better fit. Completed the invention. Furthermore, the present invention was completed based on the discovery that by making the wire insertable and removable and using a wire shorter than the wire insertion portion, it is possible to support the breast and reduce the burden on the breast.

That is, the present invention has the following configuration.
[1] A brassiere comprising a pair of left and right cup parts, a base part that supports the cup parts, a back part, and a strap,
The base part is continuous with the cup part and includes a skin-side base part having elasticity and a front-side base part having substantially the same shape as the skin-side base part, which are stacked on top of each other,
The skin side base part and the front side base part are fixed to each other at the front center top, side edge, and lower end,

[5] The brassiere according to [3] or [4], comprising a removable wire having a length of 70 to 90% of the length of the wire insertion portion.

According to the brassiere of the present invention, the skin-side base portion, which is a member that comes into direct contact with the skin, has elasticity, and the skin-side base portion and the front-side base portion are overlapped, and the skin-side base portion and the front-side base portion are overlapped. Adjusting the under position of the left and right breasts by a structure including an elastic member extending from between the base part and covering the surface of the skin-side base part and the surface of the cup part, and changing the left-right difference over time. In addition to being able to accommodate various body shapes, it fits people of various body shapes without causing a feeling of pressure, and even if the condition or balance of the left and right breasts changes, it can protect the surgical site depending on the condition at the time. , it is comfortable to wear and provides a symmetrical appearance.

Furthermore, the brassiere of the present invention having a structure in which a wire insertion part is provided on the surface of the front base part can particularly support the breast while reducing pressure on the breast (particularly the lower part of the breast). These features do not inhibit the wound healing process after breast reconstruction, can cope with long-term changes in breast shape, are gentle on the skin, prevent long-term complications, and create symmetry. A bra that can maintain breasts for a long period of time is provided. In particular, by using a wire shorter than the wire insertion portion, the breast can be supported and the burden on the breast can be reduced.

It is a figure showing the inside of the front side base part of the brassiere of Example (A) and Reference Example (B) of the present invention. It is a figure showing the wire insertion/extraction opening of the brassiere of the example of the present invention and its vicinity.

Hereinafter, embodiments for carrying out the present invention will be described in more detail with reference to the drawings, but the illustrated embodiments are merely examples. The invention is not limited to the embodiments shown here.

FIG. 1 shows the entire surface (clothing side) of a brassiere 1 that is an example of the present invention. The brassiere 1 includes a pair of left and right cup parts 2, a base part 3 that supports the cup parts 2, a back part 4 that connects to the base part 3, and a strap 5 that connects the cup part 2 and the back part 4. Equipped with. A hook 6 is provided at the end of the back portion 4. The left and right back parts 4 can be freely engaged with and detached from each other by hooks 6.

The base part 3 is formed by overlapping a front side base part and a skin side base part, which have substantially the same shape. In FIG. 1, only the front base portion 31 is shown. The front base portion 31 has a wire insertion portion 7 provided on its surface. The curve of the wire insertion part 7 is substantially the same as the curve of the lower edge of the cup part 2. The front base portion 31 is hollowed out at a portion corresponding to the cup portion 2. A joint portion 8 between the base portion 3 and the back portion 4 (side edge portion of the base portion) is sewn. The length L from the lowest part of the wire insertion part 7 to the lower end of the base part 3 is about 2.5 cm in the example of FIG. 1. The length L is preferably about 2 to 3 cm. By setting the length L from the lowest part of the wire insertion part 7 to the lower end of the base part 3 to be about 2 to 3 cm, the skin side base part can be expanded and contracted, and the front side base part and the skin side base part can be easily connected. It is possible to obtain a bra that has less misalignment and wrinkles, has excellent breast support, and is comfortable to wear.

In the embodiment shown in FIG. 1, the front center of the lower end of the base portion 3 is located above both sides, and is formed in a constricted shape with the front center as the apex. The lower end is not limited to this shape, and may be linear, for example. Further, in the embodiment shown in FIG. 1, the wire insertion part 7 is provided over the entire curved part of the hollow corresponding to the cup part 2. On the other hand, as another embodiment, it is also preferable to provide the wire insertion part only in a part of the curved part of the hole corresponding to the cup part. Specifically, it is also preferable that the wire insertion part does not extend to the front center top, but ends approximately 1 to 2 cm below the front center top.

The back portion 4 can be made of a known material selected as appropriate; for example, a material with elasticity such as power net or cotton knit may be used, or a material with low elasticity or a material with almost no elasticity may be used. You can also use The upper end or lower end of the back portion 4 may be reinforced with a highly stretchable material in the length direction, such as a stretch tape such as bias tape. When a stretch tape is provided, the stretch tape may be placed on either the front side or the skin side of the back part 4, but when the stretch tape is attached to the front side, the unevenness on the skin side is reduced, so that it is more comfortable to wear.

Further, in the example of FIG. 1, the hooks 6 have four stages, but the number of hook stages may be smaller (two stages, three stages) or more (six stages, eight stages). Having a large number of hooks is preferable because it makes it easier to adjust the degree of compression according to changes in physical condition and body shape, and one size can accommodate users with a variety of body shapes.

FIG. 2 shows the back side (skin side) of the brassiere 1. The cup portion 2 includes an under adjustment pocket 21 and a volume adjustment pocket 22. The under adjustment pocket 21 extends from the front center apex CT of the cup part 2 along the lower edge CU of the cup part 2, and reaches the side apex ST. In the example of FIG. 2, the vertical width of the under adjustment pocket 21 is such that it covers the lower half of the cup, but the pocket may have a narrower vertical width. The opening of the under adjustment pocket 21 is provided on the inside. In other words, the under-adjustment pocket 21 is open toward the front side of the brassiere to prevent unevenness from occurring on the skin side. By reducing the unevenness on the skin side, it is possible to prevent the bra fabric from hitting the breast locally and damaging the skin.

A skin-side base portion 32 is provided continuous with the cup portion 2. The connecting portion 23 between the cup portion 2 and the skin-side base portion 32 (that is, the lower edge CU of the cup portion 2) is edged with non-stretch tape, and no wire is inserted. The skin-side base portion 32 is made of a stretchable material, and it is particularly preferable to use a material that is stretchable in both the vertical and horizontal directions. As the material, for example, power net, elastic lace, knit, etc. can be used. In the example of FIG. 2, a power net is used for the skin-side base portion 32. The lower end of the skin-side base portion 32 is reinforced with elastic tape. The length L from the lowest part of the lower edge CU of the cup part 2 to the lower end of the skin-side base part 32 is about 2.5 cm in the example of FIG. 2, like the front side, and can be about 2 to 3 cm. preferable.

In the brassiere of the present invention, since the skin-side base portion 32 has elasticity, it is possible to reduce pressure on the lower part of the breast where pressure is particularly likely to occur. Furthermore, by employing a material that expands and contracts in both vertical and horizontal directions for the skin-side base portion 32, it is possible to prevent the fabric of the brassiere from touching the breast locally and to evenly support the entire lower part of the breast. With this configuration, for example, angiogenesis after autologous tissue transplantation into the breast is less inhibited, and it is thought that the risk of tissue degeneration and scarring can be lowered.

Although the material of the cup portion 2 is not particularly limited, it is preferable that the cup body is made of a non-stretchable material. Further, since the back surface of the cup portion 2 comes into direct contact with the skin, it is preferable to use a material that is comfortable to the skin, such as cotton knit, polyester material, polyurethane material, cotton and polyester blend material, cotton and polyurethane blend material, etc. Further, an elastic lace 9 is located on the front side of the cup portion 2, and a flat rubber 10 is attached to the upper end of the back side of the elastic lace 9. By arranging the elastic lace 9 and the flat rubber 10 on the front side of the cup portion 2, the upper part of the breast can be fitted without being excessively compressed, thereby improving support and wearing comfort. Stretch tape can also be used instead of flat rubber. In the example of FIG. 2, the width of the flat rubber 10 is 5 mm, but a width of about 4 to 8 mm can be used depending on the design and purpose.

A strap 5 is connected to the elastic lace 9 and the flat rubber 10. That is, the strap 5 and the cup portion 2 are connected via an elastic lace 9 and a flat rubber 10, which are elastic members. This configuration is preferable because it makes it easier to obtain a good fit regardless of the condition or volume of the breast. In addition, in the example of FIG. 2, the stretchable lace 9 is used, but instead of the stretchable lace, a stretchable knit material or the like may be used. In addition, as another example, the strap and the cup part may be connected via a non-stretchable member, or the strap and the cup part may be directly connected.

The elastic lace 9 is a series of elastic members extending from between the skin-side base part 32 and the front-side base part 31 and covering the surface of the skin-side base part 32 and the surface of the cup part 2. The stretchable lace 9 covers the entire skin-side base part and the cup part, and extends from the lower end of the base part to above the upper edge of the cup part. When covering the area from the skin-side base to the cup with a series of elastic members, the elastic members can stretch to support the breast, for example, even if the breast has a large volume, resulting in a better fit. There are advantages.

FIG. 3 particularly shows the pocket portion of the cup portion 2, and is a view looking down from above on the back surface of the cup with the space between the two pockets provided in the cup portion 2 widened. The cup portion 2 is provided with an under adjustment pocket 21 on its skin side, and the under adjustment pocket 21 is provided with an opening 25 inside thereof for inserting and removing a pad. Further, a volume adjustment pocket 22 is provided on the back side of the cup portion 2 and on the front side of the under adjustment pocket 21. The volume adjustment pocket 22 is a pocket large enough to occupy almost the entire cup portion 2, into which an arbitrary pad can be inserted in order to adjust the difference in volume between the left and right breasts. In addition to the illustrated example, the volume adjustment pocket 22 can be a pocket that occupies any part of the cup, such as the side of the cup, the upper half of the cup, or another part. Moreover, it is good also as a structure provided with several volume adjustment pockets. The volume adjustment pocket 22 is provided with an opening 26 inside thereof for taking the pad in and out. In other words, the volume adjustment pocket 22 is provided so as to open toward the skin side of the brassiere.

FIG. 4 shows a state in which the under adjustment pad is inserted into the under adjustment pocket 21 on one side (right side) of the cup. No pad is inserted into the other cup (left). When the under adjustment pad is inserted, the entire lower edge of the cup is covered with padding. If the underside position of the left and right breasts of the user is different, the apparent underside position can be adjusted by inserting an underside adjustment pad into the cup on the side where the underside position is relatively high. If the position of the underside of the left and right breasts is different, problems may occur such as the bra tilting even when worn, the line of the clothes being distorted, and the bra not being comfortable to wear. However, by adjusting the underside position, these problems can be solved. I can solve the problem. In addition, if the under position of the left and right breasts was different, the bra would have to be supported only by the shoulder on the side with the lower under position, which caused stiff shoulders and placed a heavy burden on the body. can reduce the burden on

In addition, by providing the underside adjustment pocket 21 on the skin side, the underside adjustment pad is prevented from shifting upward, and the underside adjustment pad effectively functions as a base for the breast. In particular, breasts that have received implants are less flexible and less able to follow posture than biological breasts, so the pads tend to shift when wearing a bra. The under-adjustment pad can be held in an appropriate position even when the bra is worn for a long time.

Further, since the under adjustment pocket 21 and the volume adjustment pocket 22 are provided separately, it is possible to flexibly respond to cases such as when only the under position is desired to be adjusted or when only the volume is desired to be adjusted. In addition, it is equipped with an underside adjustment pocket and has a structure in which the skin-side base part has elasticity, so when the left and right underside positions are adjusted using the underside adjustment pad, the skin-side base part expands and contracts appropriately, providing a good fit. There is less stress on the body, and the under position can be aligned.

FIG. 5 shows the under adjustment pad 51. As shown in FIG. The curve of the lower edge PU of the under adjustment pad 51 has a shape that roughly follows the lower edge CU of the cup part 2 (see FIG. 4), and the front center top PCT is the front center top CT of the cup part 2, and the side top PST roughly corresponds to the side top ST of the cup portion 2, respectively. The under adjustment pad 51 is a banana-shaped pad shaped so that the width is the widest at about 3.5 cm near the bottom of the barge line and gradually narrows in the side direction. The thickness of the under adjustment pad 51 is approximately 1 cm. By adopting such a shape, a natural verge line is formed, and the effect of adjusting the left and right under positions is excellent. The under adjustment pad 51 may have any shape other than the example shown in FIG. 5, such as having different widths and thicknesses, or having a rounded shape. For example, the widest part can be about 1 cm to 4 cm, and the thickness can be about 0.5 cm to 3 cm.

The material for the under adjustment pad and the volume adjustment pad can be selected from known materials depending on the purpose and design. For example, a material having elasticity and moldability such as natural fibers and/or synthetic fibers such as cotton, urethane foam resin, silicone, etc., wrapped in fabric such as tricot can be used.

FIGS. 6A and 6B are views showing a part of the inner structure of the front base part 31 seen from the front side of the brassiere 1. FIG. 6(A) shows an embodiment of the present invention, in which an elastic lace 9 is located inside the front base part 31 and on the front side of the skin base part 32 or the cup part 2. The elastic lace 9 is not sewn to the lower edge of the cup part 2, but extends continuously from the lower end of the base part to above the upper edge of the cup part.
FIG. 6(B) is a reference example, in which the elastic lace on the surfaces of the cup part 2 and the skin-side base part 32 is sewn to the lower edge of the cup part 2. In the reference example, the elastic lace disposed on the surface of the skin-side base portion 32 and the elastic lace attached to the surface of the cup portion 2 are separate members.

The front side base part 31 and the skin side base part 32 are fixed to each other by the cup front center top CT, the lower end of the base part 3, and the side edge 8 of the base part. As shown in FIG. 6, the lower edge of the cup portion 2 and the wire insertion portion 7 are not fixed to each other except at both ends (the front center apex CT and the side apex ST). In addition to sewing, any other method can be used for fixing, such as adhesion or using a clip-like engagement member.

In the brassiere of the present invention, in the base part 3, the front side base part 31 and the skin side base part 32 are overlapped, only a part of them is fixed, and furthermore, the front side base part 31 and the skin side base part 32 are positioned between the skin side base part and the front side base part. However, due to the structure that includes an elastic member that covers the surface of the skin-side base and the surface of the cup, the circumference of the cup expands and contracts according to the size of the breast to fit the breast, and the elastic member covers the entire breast. Because it wraps around you, it provides adequate support even when using a bra without wires. Furthermore, when using a bra with wires, the wires do not excessively compress the breasts. Furthermore, since the cup and wire are not fixed to each other, the cup will not deform even if the shape of the wire to be inserted is changed, and the wire to be inserted can be selected depending on the physical condition, postoperative course, changes in body shape, etc. or can be changed. For example, even if different wires are used for the left and right sides, the skin-side base portion expands and contracts to fit the left and right cups to the breasts, and the wires support the area around the breasts.

As for the wire, in addition to the basic wire with approximately the same curve as the lower edge of the cup portion 2, wires with different verge line widths (pitch) and curves, wires made of softer materials, etc. can be selected and used as appropriate. Can be done. The wire may be one that extends from the front cup central apex CT to the armpit apex ST of the cup, or may be a shorter wire that corresponds to only a portion of the verges line, and is not particularly limited. In particular, it is preferable to use a wire with a length of 70 to 90% of the length of the wire insertion portion. As the material of the wire, known materials such as plastic and metal wire can be used.

You can choose the presence or absence of a wire, the shape and length of the wire, and the configuration in which the wire is placed on the surface of the bra reduces direct pressure from the wire, and furthermore, the base on the skin side expands and contracts. This provides proper support for the lower part of the breast. Depending on the type of mastectomy, the tissue around the axilla may become thin even after breast reconstruction, and in such cases, there is a risk of skin damage due to contact with the armpit wire, but it is important to consider the presence or absence and shape of the wire. Since it can be selected, it is thought that the causes of such subsequent events can be reduced.

FIG. 7 is an enlarged view of the cup 2 and the wire insertion part 7. FIG. 7A shows the normal state, and FIG. 7B shows the state when the wire is inserted and removed. That is, the wire insertion part 7 is provided with a wire insertion/extraction port at least at one end thereof, and a cover member 71 is provided on the surface side thereof. The end of the wire insertion portion 7 is not sealed and serves as a wire insertion/extraction port 72. When inserting or removing the wire, the wire 73 can be inserted or removed from the wire insertion/extraction port 72 located under the cover member 71. Providing the cover member 71 on the front side prevents the wire from coming off, makes it easier to take in and take out the wire, and has less unevenness on the back surface, so it feels good on the skin. In the example of FIG. 7, the cover member 71 covers about 3 cm from the end of the wire insertion portion 7, but this can be changed as appropriate depending on the design.

By making the wires insertable and removable, it is possible to select the presence or absence of the left and right wires, as well as the size of the wires, depending on the postoperative course and the condition of the surgical site. In addition, the wire can be inserted and removed freely, the wire insertion part and the cup part are separated, and the base part of the cup part (skin side base part) is made elastic, so that the wire can be inserted only on one side. Or, even if different wires are used for the left and right sides, the elasticity of the skin-side base allows the difference to be adjusted, resulting in a good fit and a natural appearance.

The bra of the present invention is particularly useful for those with breast reconstruction experience, and is particularly useful for those who have undergone breast reconstruction, and can solve problems such as the difference in the left and right underside positions, the difference in size, and the presence or absence of wires in the bra after breast reconstruction. can be solved at the same time. Note that what has the structure of the brassiere of the present invention is not limited to a brassiere, but may also be a slip with a bra, a bra camisole, or the like.
