Description

Telescopic mold cup with sandwich structure and underwear

Technical Field

The application relates to the field of bra underwear, in particular to a telescopic mold cup with a sandwich structure and underwear.

Background

The bra underwear is close-fitting clothing worn by women in daily life, and plays roles of supporting, supporting and protecting the breasts of the women. The bra underwear in the market has various styles and colors, and comprises adjustable underwear, sports underwear, traceless high-elasticity underwear and the like.

For example, the adjustable underwear is generally manufactured by sewing a split mold cup or a half mould enclosing cup, the split mold cup is manufactured by connecting a plurality of adjusting parts such as side supporting pieces, bottom supporting pieces and the like in a sewing mode, and the effect of adjusting the chest shape is achieved by arranging a plurality of side supporting pieces and bottom supporting pieces; although the adjustable underwear with a plurality of adjusting components connected by sewing has a good shaping adjusting effect, the adjustable underwear generally adjusts a specific chest shape, as shown in figure 1, cup pads with specific code numbers are adopted according to different chest shapes and sizes, namely the cup pads are 'one cup and one yard', the peripheries of the cup pads are basically and uniformly zoomed in and out according to the chest shape of a human body in the aspect of the size proportion of the chest cup, and then the chest shapes of a user are adjusted in a targeted manner by combining the sewing connection of a plurality of side supporting pieces and bottom supporting pieces, so that the application range of the manufactured split mold cup corresponding to different chest shapes is limited, the splicing seams of the side supporting pieces and the bottom supporting pieces are more, the friction of the splicing seams to the skin of the body after wearing is larger, the wearing discomfort is easy to generate, and meanwhile, the air permeability of the split mold cup can be reduced by the plurality of side supporting pieces and the bottom supporting pieces; in addition, such adjustment type underwear generally wears comparatively closely in order to play and gathers together the adjustment effect, but under the tight condition of wearing, the chest that a plurality of side holds in the palm piece, the bottom support piece that set up arouses closely to feel, influences the gas permeability and the travelling comfort of dress. For the half mould surrounding cup, the cup part and the lower part are not provided with splicing seams, so that the friction of the splicing seams on the skin of a human body is reduced, but the cup part and the lower part are both made by bonding cotton and fabric, the air permeability is lower, the lower part is close to be free of elasticity, the situation that the body is tightly tightened by pulling down is easy to occur when the half mould surrounding cup is worn, the requirement of an adjustable underwear structure without the splicing seams on the body of the human body is higher, a consumer difficultly selects a proper size of the chest shape matched with the lower part of the lower part, and the situation that the size of one cup is limited also exists.

For solving the problems of wearing oppression and tight feeling of the adjusting type mold cup, the cup inserting type underwear is pushed out from the market, as shown in the attached figure 2, a cup pad taking and placing opening is formed in the inner layer fabric, then the surface layer fabric and the inner layer fabric are attached through glue applying modes such as glue dispensing and the like, a cup pad accommodating cavity is reserved in the middle of the underwear, the attached surface layer fabric and the inner layer fabric are of a planar structure, then the two layers of fabrics are molded together to form a cup three-dimensional structure, and then the cup pad is placed in the cup pad accommodating cavity; the size of this coaster is corresponding with the size in coaster holding chamber to make the coaster be difficult for appearing running the cup phenomenon in coaster holding intracavity, and the two-layer surface fabric at cup position generally adopts high elasticity surface fabric such as four sides bullet, the coaster is got and is put near the surface fabric of mouth and all has elasticity, be convenient for get and put the coaster, and the area in general coaster holding chamber is slightly bigger than the coaster area, the elastic energy that combines the surface fabric provides tensile elasticity for the coaster that the yardstick is slightly bigger, make this kind of coaster of cup formula underwear ability holding of inserting a plurality of yardsticks. However, the cup-inserted underwear is not fixed with the underwear fabric due to the fact that the cup pad can be placed, and the stretching elasticity provided by the fabric elasticity enables the supporting and supporting effects on the chest to be weak, and mainly only has the functions of simply covering the chest and preventing salient points, for example, when a woman with a large chest size wears the underwear, the situation that the chest is too stretched due to the fact that the fabric is stretched for accommodating a large chest size is easy to occur, the situation that the chest is sagged and expanded after wearing the underwear is caused, and the requirements of supporting and supporting the chest such as chest sag, chest expansion and the chest shape being more than C cup cannot be met; and the cup pad of this kind of insert cup formula underwear is not fixed connection between two-layer surface fabric at cup position, after wearing and washing, the phenomenon that the cup pad shifts in underwear cup position appears easily, can appear the condition that the cup pad slided out, breaks away from in the underwear cup position even, is not suitable for in the type of moulding underwear product or the motion underwear product that need support bearing effect, and application scope is restricted.

To this, to the coaster of solving cup type underwear shift easily in cup portion, the cup problem of race of roll-off, also the position that the release is close to heart position or is close to lower portion of enclosing at the coaster on the market sets up the glued membrane strip, as shown in figure 3, it is fixed mutually with the surface fabric at cup position to wrap the position through this glued membrane strip, presents the local fixed knot structure between coaster and the surface fabric of cup position, makes coaster and the laminating of cup position surface fabric stable, is difficult for race the cup. Although the cup-inserting type underwear with the locally fixed cup pad can improve the cup sliding problem of the cup pad in the cup part, the situation that the cup-inserting type underwear has low supporting effect on the chest is still not improved. Furthermore, as shown in fig. 1, the objective rules of the breast shape and the mold cup size are that the size ratios of the breast cup sizes a, B, C and the like are scaled according to the breast shape of the human body, specifically, the periphery of the mold cup is scaled approximately uniformly to form mold cups with different sizes, but at present, the semi-fixed cup-inserted underwear product with adhesive film strips arranged at the positions of the cup pad close to the heart or the lower periphery is limited in the size from the edge of the cup close to the lower periphery to the breast point of the cup, or limited in the size from the edge of the cup close to the heart to the breast point of the cup, so that the scaling of the mold cup does not accord with the objective rules, and women with larger breast size can approach the lower periphery or the mold cup to the heart when wearing, so that the positions of the breast point of the human body and the breast point are dislocated, thereby reducing the supporting performance and wearing comfort of the mold cup on the breast.

Therefore, the underwear adopting a fixing mode at a cup pad corresponding to a cup position, a position close to a heart of a chicken, a position close to a lower periphery and integrally fixed between the cup pad and a cup position fabric is also pushed out in the market, and on the basis of solving the problem that the cup pad is easy to shift in the cup position and slide out, the problem that the breast supporting effect of the cup position is insufficient, and the wearing comfort is low due to the fact that the breast position of a human body is staggered with the breast position of a mold cup when the underwear is worn is solved.

For the related underwear products, the applicant thinks that the current adjustable underwear and cup pad full-fixation underwear has better support property on the chest, but has limited application range on different chest types and weaker chest type containing applicability; the cup-inserting type underwear is suitable for various chest-type sizes, but has the cup-running phenomenon and weak supporting force on the chest; although the cup pad semi-fixed underwear can solve the problem that a cup pad runs a cup, the dislocation of the breast point of the chest of a human body and the breast point of a mold cup is easy to occur, the wearing comfort is reduced, the supporting and supporting functions on the chest are weak, the semi-fixed underwear is not suitable for women with large chest sizes, and the existing underwear products cannot solve the problem that the supporting performance of the underwear is balanced with the application range of the chest.
