Description

FILED OF THE INVENTION

The present application relates to the field of female underwear technologies, and in particular, to a cup with hollow lower bowl and a one-piece cup with hollow lower bowl.

BACKGROUND OF THE INVENTION

A brassiere is one of indispensable articles for use in the daily life of women. With the development of the technology, more and more kinds of brassieres are developed, such as a brassiere with good air permeability, a brassiere comfortable to wear, an antibiotic brassiere, or the like, to meet different demands of women.

The brassiere is generally formed by connecting cups and a shoulder strap, the cup is the most important part of the brassiere, and whether a woman may comfortably wear the brassiere largely depends on fit of the cup and the breast. By the brassiere produced by the cups on the current market, when the arm of the woman is lifted up, movement of the shoulder may cause movement of the shoulder strap, and the shoulder strap bears an upward force, so as to move the cup upwards, which leads to cup displacement, such that the cup does not fit the breast any more, resulting in an uncomfortable wearing.

SUMMARY

The present application provides a cup with hollow lower bowl, so as to solve the problem of cup displacement of a brassiere when a woman lifts her hand.

In a first aspect, the present application provides a cup with hollow lower bowl, which adopts the following technical solution.

A cup with hollow lower bowl includes a cup body, the cup body is divided into an upper bowl and a lower bowl integrally formed with the upper bowl, a cradle extends from the lower bowl, and a plurality of ventilation notches are defined at intervals at a joint of the lower bowl and the cradle.

When the arm of a woman is lifted up, the cup slides upwards under a dragging action of a shoulder strap and does not fit the breast, and when the arm of the woman is withdrawn downwards, the cup cannot return to a proper position, to completely fit the breast and press the breast. In order to reset the cup, the cup is required to be adjusted, which is troublesome. Therefore, in the present application, a buffer zone is formed by providing the plurality of ventilation notches at intervals at the joint of the lower bowl and the cradle, such that the cup may completely fit the breast when the woman lifts the arm up, thereby reducing cup displacement. When the arm is lifted up, the shoulder strap drives the upper bowl and the lower bowl to move upwards, the ventilation notch is deformed to form the buffer zone. Since the buffer zone separates the lower bowl from the cradle, a dragging force applied by the lower bowl to the cradle is smaller than a contact friction force of the cradle and the breast, such that the cradle may stably fit the breast, thereby effectively reducing the cup displacement. Meanwhile, the capacity of a cup body can be expanded to cover one size more, thereby improving a wearing comfort. In addition, the ventilation notch may improve air permeability of the cup, such that the breast may be kept in a dry and comfortable state, and the practicability is high.

Optionally, each of the plurality of ventilation notches has a width of 4-10 mm.

If the width of the ventilation notch is less than 4 mm, the area of the buffer zone formed by the ventilation notch is small when the arm is lifted up, such that the dragging force applied by the lower bowl to the cradle is greater than the contact friction force of the cradle and the breast. When the hand is lifted up, the cradle moves upwards, such that a cup displacement is prone to be caused. If the width of the ventilation notch is greater than 10 mm, the area of the buffer zone formed by the ventilation notch is large when the arm is lifted up, such that the dragging force applied by the lower bowl to the cradle is smaller than the contact friction force of the cradle and the breast, the ventilation notch is difficult to reset, which is not conducive to the fit of the cup and the breast, such that the brassiere is uncomfortable to wear.

Optionally, each of the plurality of ventilation notches is arc-shaped, intermittent arc-shaped, zigzag, waved or rhombic.

By adopting the technical solution, the area of the buffer zone formed by the ventilation notch is large, such that the shape of the area of the buffer zone may be flexibly changed. When the hand is lifted up in any direction, the shape of the buffer zone can be changed with the change of the arm direction, thus reducing the cup displacement. Meanwhile, the air permeability of the cup is increased, sweat may be discharged conveniently, bacterium breeding in the cup is reduced, and the cup is kept clean, dry and comfortable, thereby improving the wearing comfort.

Optionally, each of the upper bowl, the lower bowl and the cradle sequentially includes a composite layer and a first cloth layer from outside to inside, the composite layer is bonded to the first cloth layer, a side of the composite layer away from the first cloth layer is in contact with an outerwear, a side of the first cloth layer away from the composite layer is in contact with a breast, and the plurality of ventilation notches are defined in the composite layer and penetrate through the composite layer.

By adopting the technical solution, the cup is light and thin and has good air permeability. When the ventilation notch is deformed, the first cloth layer fits the breast, such that the cup may stably fit the breast during the movement of the hand, thereby reducing the cup displacement. The first cloth layer is connected with the composite layer, and the first cloth layer applies a dragging force to the composite layer, such that the deformed ventilation notch recovers rapidly, thus the cup may more stably fit the breast.

Optionally, the first cloth layer is an elastic cloth layer.

By adopting the technical solution, the cup is not prone to deformation during dragging. The elastic cloth has good elasticity. The elastic cloth is driven by the shoulder strap to be deformed when the hand is lifted up, meanwhile the ventilation notch is also deformed, such that the cradle may stably contact the breast, so as to avoid the cup displacement, and a recovering effect may be rapidly achieved after being dragged, to maintain the shape of the cup.

Optionally, the composite layer sequentially includes a second cloth layer, a first sponge layer and a second sponge layer, the first sponge layer is connected with the second cloth layer, and the second sponge layer is connected with the first cloth layer.

By adopting the technical solution, the cup is thin, whose performances, such as ventilation, the comfort, softness, or the like, are improved, and the sponge layer has a porous structure, thus facilitating sweat absorption and moisture elimination, so as to reduce a stuffy feeling.

Optionally, the composite layer further includes a formed net layer, and the formed net layer is provided between the first sponge layer and the second sponge layer.

The formed net has a hard texture and is not prone to deformation, such that the cup may be used for a long time without deformation. After the shaped net layer, the first sponge layer and the second sponge layer are pressed and shaped, the shaped net may support the first sponge layer and the second sponge layer for a long time because the first sponge layer and the second sponge layer have a soft texture and cannot be shaped, so as to keep the cup from deforming.

Optionally, a hot melt adhesive film for bonding is provided between the first cloth layer and the second sponge layer, and the hot melt adhesive film is one of a Thermoplastic Urethane (TPU) film, a Polyamide (PA) film and a Polyethylene vinylacetate (EVA) film.

By adopting the technical solution, the first cloth layer and the second sponge layer can be firmly bonded. The TPU film, the PA film and the EVA film have soft textures, good air permeability and good viscosity, and are resistant to washing. The cup which is thermally bonded by the TPU film, the PA film or the EVA film is not stuffy and has a good moisture elimination effect. In addition, after multiple times of washing, the first cloth layer and the second sponge layer may be stably connected.

In a second aspect, the present application provides a one-piece cup with hollow lower bowl, which adopts the following technical solution.

A one-piece cup with hollowed lower bowl includes a connection portion and two sub-cups with hollowed lower bowl, the two sub-cups with hollowed lower bowl are symmetrically arranged and are integrally formed with the connection portion, and each of the two sub-cups with hollowed lower bowl is configured as the cup with hollowed lower bowl according to the first aspect. By adopting the technical solution, the produced underwear has a ventilation effect, is not stuffy and has a good moisture elimination effect, additionally, the cup may completely fit the breast, thereby reducing cup displacement and further improving a wearing comfort.

In summary, the present application at least has the following beneficial effects.

1. In the present application, the buffer zone is formed by providing the plurality of ventilation notches at intervals at the joint of the lower bowl and the cradle, such that the cup may completely fit the breast when the woman lifts the arm up, thereby reducing the cup displacement.

2. Since the ventilation notch is arc-shaped, intermittent arc-shaped, zigzag, waved or rhombic, the area of the buffer zone formed by the ventilation notch is large, the shape of the area of the buffer zone may be more flexibly changed, such that when the hand is lifted up in any direction, the shape of the buffer zone may be changed with the change of the arm direction, thus reducing the cup displacement. Meanwhile, the air permeability of the cup is increased, such that sweat may be discharged conveniently, which reduces the bacterium breeding in the cup, to keep the cup clean, dry and comfortable, thereby improving the wearing comfort.

3. By the hollow one-piece cup according to the present application, the underwear has a ventilation effect, is not stuffy and has a good moisture elimination effect, and the cup may completely fit the breast, thereby reducing the cup displacement and further improving the wearing comfort.
