Description

[Technical Field]

[0001] This invention relates to a new insert pad for brassieres that leaves no pad marks on the bust. [Background technology]

[0002] The inside of the bra cups has pockets for storing pads, and by inserting the most suitable insert pads according to the shape and volume of the wearer's bust, the bust can be complemented, creating an attractive cleavage and a beautiful, voluminous décolleté around the chest.

[0003] Conventionally, insert pads have been available in various shapes, but here we will use a round pad 200. The round insert pad 200 is inserted along the inner surface 120a of the cup 120 of the brassiere 100, so the outer surface 200b of the insert pad 200 is formed in a hemispherical shape so as to fit along the inner surface 120a of the cup 120 of the brassiere 100. The inner surface 200a of the insert pad 200 comes into contact with the bust B via a thin pocket cloth 140, so its thickness is gradually tapered from the center of the insert pad 200 towards the outer circumferential edge 240 to fit the bust B (see, for example, Patent Document 1).

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-300593 Summary of the Invention [Problem to be solved by the invention]

[0005] The insert pad 200 is formed into the above shape by molding a foam fabric made by bonding woven fabric to both sides of a thick foam sheet using a bowl-shaped mold, which results in a hard, thin edge surface around the entire periphery of the outer edge 240 of the insert pad 200. As described above, the insert pad 200 is formed by molding a thick foam fabric, and this edge surface faces the plane M including the outer edge 240 of the insert pad 200, and furthermore, the compression rate is high, making the outer periphery hard (FIG. 6).

[0006] When the brassiere 100 is worn with this insert pad 200 inserted into the pocket P of the brassiere 100, the hard outer edge 240 of the insert pad 200 continues to contact the bust B through the thin pocket cloth 140 while the brassiere is being worn. Since the insert pad 200 is continuously pressed against the cup 120 of the brassiere 100 while the brassiere 100 is being worn, as shown by the arrow, there was a problem that circular pad marks X were formed on the bust B when the brassiere 100 was worn for a long period of time.

[0007] The object of this invention is to provide an insert pad for a brassiere that does not leave marks on the bust from the outer edge of the insert pad even when the brassiere is worn for a long time. [Means for solving the problem]

[0008] The device described in claim 1 (Fig. 3(a)) is an insert pad 20 for a brassiere 10, which is formed by molding a foam fabric and is composed of a cup-shaped main body portion 21 and an outer edge portion 22 that extends like an outer brim from the opening of the main body portion 21. a connecting portion 23 between an inner surface 21a of the main body portion 21 and a surface 22a of the outer edge portion 22 connected to the inner surface 21a is formed into a curved surface having a continuous arc-shaped cross section; and The outer edge portion 22 is formed parallel to a plane M that is in contact with the outer edge portion 22.

[0009] The device described in claim 2 (Fig. 3(b)) is an insert pad 20 for a brassiere 10, which is formed by molding a foam fabric and is composed of a cup-shaped main body portion 21 and an outer edge portion 22 that extends like an outer brim from the opening of the main body portion 21. a connecting portion 23 between an inner surface 21a of the main body portion 21 and a surface 22a of the outer edge portion 22 connected to the inner surface 21a is formed into a curved surface having a continuous arc-shaped cross section; and The outer peripheral edge 24 of the outer peripheral portion 22 is formed so as to be located closer to the top 25 of the main body portion 21 than a plane M that contacts the outer peripheral portion 22.

[0010] The invention described in claim 3 is "an insert pad 20 for a brassiere 10 according to claim 1 or 2, The thickness of the main body portion 21 from the top 25 of the main body portion 21 to the outer edge portion 22 is formed so as to gradually decrease toward the outer edge portion 22, and the outer edge portion 22 is formed in a plate shape. [Effects of the Invention]

[0011] According to this invention, when the brassiere 10 is worn, the connecting portion 23 formed on the curved surface of the convex arc-shaped cross section between the main body portion 21 and the outer edge portion 22 of the insert pad 20 comes into contact with the bust B, and no impression (pad mark) X of the outer edge portion 22 of the insert pad 20 is left on the bust B even when worn for a long time.

DETAILED DESCRIPTION OF THE INVENTION

[0013] The present invention will be described below with reference to the drawings. As shown in Figure 1, a brassiere 10 to which the insert pad 20 of the present invention is applied is roughly composed of a pair of left and right cups 12, a front center 30 connecting the pair of left and right cups 12, front panels 35 sewn to the sides of the cups 12, side panels 40 extending from both front panels 35, and shoulder straps 50. Pocket fabric 14 is sewn to the inner surface 12a of the cups 12, and a pocket opening 16 is provided on the shoulder strap 50 side. In contrast, in the case of the peanut-shaped insert pad 20, a pocket opening 16 is provided at the connecting portion of the left and right cups 12 (not shown).

[0014] The cups 12 are broadly divided into several types depending on their shape, including full cups, 3 / 4 cups, half cups, and various other types. Structurally, for example, outer and inner fabrics are attached to both sides of a urethane foam interlining formed into a cup shape. The interlining is adjusted to an appropriate thickness so that it does not lose breathability and become stuffy, and is flexible enough to fit comfortably around the bust (b).

[0015] The side panels 40 are strip-shaped members made of a highly stretchable fiber material, and one end of the side panels 40 is sewn to the armpit edge of the front panel 35. A fastening device is attached to the tip of one of the side panels 40, and a hook that can be fastened to the fastening device is attached to the tip of the other side panel 40.

[0016] The shoulder straps 50 prevent the cups 12 from shifting position and also lift and hold the bust B contained in the cups 12, with one end of the shoulder straps 50 connected to a shoulder strap attachment part provided on the upper side of the cups 12 and the other end connected to the upper edge of the side panel 40 located on the back side.

[0017] The insert pad 20 is inserted through the pocket opening 16 of the pocket cloth 14 as described above, and is used by aligning it with an appropriate position on the inner surface 12a of the cup 12. The insert pad 20 comes in a variety of external shapes. For example, there are round, teardrop, heart, and lemon shapes that are used in pairs, and there are also peanut shapes where the left and right sides are connected. In all insert pads 20, the outer edge portion 22 is compressed and thin like a plate, and the portion inside the outer edge portion 22 (this portion is referred to as the main body portion 21) is formed to be thicker than the outer edge portion 22.

[0018] The thickness of the main body portion 21 varies depending on the type, and some have a thickness that gradually decreases from near the top 25 toward the outer edge portion 22, and some have the main body portion 21 divided into upper and lower halves, with the lower half being thicker than the upper half to increase the volume of the bust B. Below, a round insert pad 20 will be explained as a representative example.

[0019] The insert pad 20 is made of a foam material. The foam fabric is, for example, a thick sheet of urethane foam material that serves as a core with woven fabric attached to both sides, and various types of foam material are used depending on the application and purpose, such as foam materials with different expansion ratios, i.e., different hardness, or foam materials with multiple ventilation holes drilled at specified intervals.

[0020] The round insert pad 20 of the present invention has a circular front shape and is composed of a cup-shaped main body 21 and an outer edge portion 22 that extends like an outer brim from the opening of the main body 21, and is formed by molding foam fabric. The outer edge portion 22 extends inward from the outer peripheral edge 24 by a width H and is provided around the entire periphery of the opening of the main body portion 21. The portion connecting the main body portion 21 to the outer edge portion 22 is a connecting portion 23.

[0021] The thickness of the insert pad 20 is formed so as to gradually decrease from the top 25 of the main body portion 21 toward the outer edge portion 22, and the outer edge portion 22 is compressed and formed into a thin plate shape. The thickness of the main body portion 21 is 7 to 12 mm at its maximum, and the outer edge portion 22 is about 1 mm. A nipple-receiving recess 27 is formed on the inner surface 21a of the top 25. The thickness of the recess 27 is formed so that the thickness of the portion surrounding the recess 27 is greater than the thickness of the recess 27 itself, and the thickness gradually decreases from the periphery of the recess 27 toward the outer edge portion 22 as described above.

[0022] In the example of Figure 3(a), the connection portion 23 between the inner surface 21a of the main body portion 21 and the surface 22a of the outer edge portion 22 connected to the inner surface 21a is formed into a curved surface with an arc-shaped cross section around the entire circumference of the opening portion of the main body portion 21, and is connected by a gently curved surface. Since the opening of the main body portion 21 is formed so as to be contained in the same plane M, the outer edge portion 22 extending like an outer flange from the opening of the main body portion 21 is also contained in the same plane M, and the outer edge portion 22 is formed parallel to the plane M that is tangent to the outer edge portion 22. Therefore, the outer peripheral end 24 of the outer edge portion 22 faces outward at a right angle to the center line that passes through the top 25 of the main body portion 21 from the inside to the outside, in other words, faces in a direction parallel to the plane M.

[0023] 3(b), the inner surface 21a of the main body portion 21, the surface 22a of the outer edge portion 22 connected to the inner surface 21a, and the connecting portion 23 between the inner surface 21a of the main body portion 21 and the surface 22a of the outer edge portion 22 are formed as a continuous curved surface with an arc-shaped cross section, and the outer peripheral edge 24 of the outer edge portion 22 is formed so as to be located closer to the top 25 of the main body portion 21 than the plane M tangent to the outer edge portion 22. In other words, the inner surface 21a of the main body portion 21 of the insert pad 20, the surface 22a of the outer edge portion 22 connected to the inner surface 21a, and the connecting portion 23 are all formed as a gentle, continuous curved surface, and the outer peripheral edge 24 is spaced apart from the plane M.

[0024] 3(b), in other words, with respect to a plane M including the outer edge portion 22, the outer edge portion 22 of the insert pad 20 extends outward integrally from the outer periphery of the main body portion 21 and is curved toward the top 25 of the insert pad 20. In other words, the cross section of the outer edge portion 22 is formed to be curved.

[0025] The manufacturing procedure for the insertion pad 20 is to cut the foamed material to the required size, and then sandwich the foamed material between a female mold with a concave bowl shape and a male mold with a convex bowl shape to mold it into a cup shape with an outer brim. After that, the compressed portion around the main body portion 21 is cut to width H to form the insertion pad 20. The compression ratio is small at the top peripheral portion centered on the top 25, which is the highest portion of the insert pad 20, and increases toward the outer edge portion 22, where it reaches its maximum compression ratio. This allows the main body portion 21 inside the outer edge portion 22 to maintain a high degree of stretch and softness. On the other hand, the outer edge portion 22 is compressed to have the highest density, and becomes a non-stretchable portion that is flexible but has almost no stretch.

[0026] Next, we will explain how to use the insert pad 20. When putting on the brassiere 10, insert the insert pad 20 into the pocket P through the pocket opening 16 and place it in the designated position inside the cup 12. In this state, the brassiere 10 is put on, and excess fat from the sides to the back is gathered toward the chest of the cup 12 and stored inside the cup 12. Furthermore, the lifting force of the shoulder straps 50 lifts the bust B and gathers it toward the chest. At this time, the top 25 and outer edge 22 of the insert pad 20 are pressed against the inner surface of the cup 12 and pushed toward the bust B, as shown by the arrows in Figure 4.

[0027] The inner surface 21a of the main body portion 21 of the insert pad 20 comes into contact with the bust B via the thin pocket cloth 14, but the outer peripheral edge 24 of the outer peripheral portion 22 is raised above the bust B and does not come into contact with the bust B. In other words, the bust B is contacted by the inner surface 21a of the main body portion 21 and the connecting portion 23 formed into a curved surface that continues smoothly from the main body portion 21, or by the flat or curved surface 22a of the outer peripheral portion 22, and the outer peripheral edge 24 of the outer peripheral portion 22, which would cause pad marks, does not come into contact with the bust B. As a result, no pad marks are left on the bust B even when the brassiere 10 is worn for long periods of time.

[0028] The above example shows a round insert pad 20, but the same applies to insert pads of other shapes, and a flange-like outer edge portion is formed on the outer periphery of the heart-shaped or lemon-shaped main body portion, and this portion comes into contact with the bust B, while the outer peripheral edge 24 does not come into contact with the bust B.

[0029] As described above, the insert pad of the present invention is an excellent product that does not leave pad marks on the bust even when wearing a brassiere for a long period of time. [Explanation of symbols]
