Detailed ways

As shown in Fig. 1, Fig. 2 and Fig. 3, a seamless bra includes a body 1, a cup 2 and an inner wrapping layer 3 integrally formed. Two symmetrical and mutually connected outward raised parts 5, the cup 2 and the inner covering layer 3 are located inside the raised parts 5, and are in a convex shape matched with the raised parts, and the front part of the main body 1 is raised The part 5, the cup 2 and the inner wrapping layer 3 are pasted together sequentially, and the cup 2 is wrapped between the raised portion 5 of the main body and the inner wrapping layer 3.

There may be one or more adhesive layers between the raised portion 5 at the front of the body 1 and the cup 2, and between the cup 2 and the inner wrapping layer 3. The raised portion 5 at the front of the body 1, the cup 2 and the The inner wrapping layer 3 is pasted together through each of the adhesive layers.

An arc-shaped frame 7 may be provided inside the lower edge 6 of the cup 2 .

The breast cup 2 may comprise an outer sandwich layer 2.1, an outer foam body 2.2, an inner foam body 2.3 and an inner sandwich layer 2.4 which are bonded to each other in sequence.

Normally, the arc-shaped frame 7 can be placed between the outer foam body 2.2 and the inner foam body 2.3. The surface of the curved skeleton 7 can be bonded (or bonded) together with the outer foam body 2.2 and the inner foam body 2.3 respectively, and the section of the curved skeleton 7 can be flat, so that the curved skeleton 7 can be connected with the cup 2. The other parts fit more firmly, and the fit (ie the lower edge 6 of the cup) is smoother.

Between the outer interlayer 2.1 and the outer foam 2.2 of the cup 2, between the outer foam 2.2 and the inner foam 2.3, and between the inner foam 2.3 and the inner interlayer 2.4, there may be one or more layers of bonding The agent layer, the outer sandwich layer 2.1, the outer foam body 2.2, the inner foam body 2.3 and the inner sandwich layer 2.4 are bonded together through each of the adhesive layers.

For making the above-mentioned seamless bra, the manufacturing method provided by the present invention includes several manufacturing processes:

(1) Make the bra body 1, wherein the two mutually symmetrical raised parts 5 at the front of the body are formed by one-time molding technology, which can adopt any suitable existing known technology (such as hot-press molding technology), the body 1 The remaining parts (such as the strap 4) can be integrally formed when the raised portion is formed, or can be formed or produced separately and then connected to corresponding parts by pressing, bonding or other methods to form an integrated body 1.

(2) To make the cup 2, first coat the materials used to make the various parts of the cup 2 with an adhesive on the surfaces that are attached to each other, stack them together according to their respective positions and sequences on the cup 2, and use a special mold The stacked materials are hot-melted and pressed to form a raised cup blank, and then the cup blank is cut into cups 2 according to the shape of the required cup. The use of adhesives ensures the lamination strength and reliability between the layers

The materials for making each part of the cup 2 may include the fabric 2.1c for making the outer interlayer 2.1, the foam material 2.2c for making the outer foam body 2.2, the steel ring 7c for making the arc-shaped skeleton 7, The foaming material 2.3c that is used to make the inner foam body 2.3 and the lining 2.4c that is used to make the inner interlayer 2.4, Fig. 4 has provided the mutual relative position and the order when each of these materials are stacked (in order to make each of the figures The material is shown clearly, and Fig. 4 draws each of the materials separately), and Fig. 5 schematically shows the method of using the cup special-purpose hot-melt pressure mold 8 to heat-melt and press the stacked cup materials into a cup blank, pressing The finished cup blank is cut to form a cup 2 .

As shown in Figure 5, the special hot-melt pressing mold 8 for cups is divided into two parts corresponding to the upper and lower parts. The superimposed cup materials are extruded at high temperature by the upper and lower parts of the mold, and the materials of each part are bonded into a whole, and have the characteristics of the mold. The formed shape thus becomes the cup blank. The materials of the outer foam body and the inner foam body shrink after being extruded at a high temperature, so that the convex part of the cup blank has high strength and high toughness, and the cup 2 produced is firm and shapely.

(3) Make the inner wrapping layer 3, adopt one-time molding technology to form the inner wrapping layer 3, and the inner wrapping layer 3 can be made with fine-grained materials, so that the brassiere can be worn more comfortably, and the one-time molding technology can adopt any suitable current There are known techniques (eg thermocompression molding technique).

(4) Brassiere assembly, the body 1, the cup 2 and the inner covering layer 3 that are made according to the production process (1), (2) and (3) are coated with an adhesive, and the front part of the body 1 The raised part 5, the cup 2 and the inner covering layer 3 are stacked together according to their position and order on the bra, the cup 2 is wrapped between the main body 1 and the inner covering layer 3, and a special mold is used for hot-melt pressing. The raised portion 5 at the front of the main body 1, the cup 2 and the inner wrapping layer 3 are bonded together to form a seamless bra, and the use of adhesive ensures the strength and reliability of bonding between the components.

The "strap" mentioned in this specification and claims refers to the part of the body other than the two protruding parts and their interconnecting parts. The strap can be used to fix the strap when worn. Formed into sheets or other shapes.

The "bonding" mentioned in this specification and claims refers to the fixed connection between the surfaces of different parts. There are many ways to realize the bonding in the prior art, and the commonly used bonding methods include Coating adhesive bonding, using a hot-melt press device to press the two parts together face-to-face, or hot-melt pressing with the adhesive applied, or any other suitable surface-to-surface fixed connection technology, The use of these specific lamination techniques constitutes a specific embodiment of the invention.

The numbering of each production process given in the specification and claims does not constitute a limitation on the order of each production process, and the production processes (1), (2) and (3) can be completed independently of each other.
