Description

Technical Field

[0001] The utility model relates to the technical field of female underwear, and more specifically to a one-piece bra and a bra forming mold. Background Art

[0002] As women's pursuit of health and comfort increases, one-piece seamless molded bras are gradually gaining popularity. At present, bras with existing molding processes are basically made of sponge attached to the fabric and sponge attached to the lining, with an intermediate layer of sponge added in the middle. After molding, they are stamped or cold-cut along the engraved line to form a mold cup. The mold cup formed by this traditional method will cause the front edge of the mold cup to be pulled due to the large compression of the sponge. The lower part is thick and hard. After wearing, with the influence of human activities and gravity, the front edge of the chest is not easy to fit, which easily leads to the empty cup phenomenon. In addition, when molding, it is generally necessary to first perform the initial molding of the surface layer and the middle layer, and then perform molding and molding together with the inner layer. This process requires the semi-finished product after the initial molding to be taken out and sprayed with glue manually, and then put back into the mold for molding and molding together with the inner layer. The process of taking out and putting back the semi-finished product needs to be re-positioned, which not only reduces the work efficiency, but also affects the positioning accuracy in the entire molding process and affects the yield rate. In addition, there are errors in manual spraying and it does not have standard operability. Utility Model Content

[0044] As women's pursuit of health and comfort increases, one-piece seamless molded bras are gradually gaining popularity. At present, bras with existing molding processes are basically made of sponge on the fabric and sponge on the lining, with an intermediate layer of sponge added in the middle. After molding, they are stamped or cold-cut along the engraved line to form a mold cup. The mold cup formed by this traditional method will cause the front edge of the mold cup to be pulled due to the large compression of the sponge. The lower part is thick and hard. After wearing, with the influence of human activities and gravity, the front edge of the chest is not easy to fit, which easily leads to the empty cup phenomenon. In addition, when molding, it is generally necessary to first mold the surface layer and the middle layer, and then mold and mold them together with the inner layer. This process requires the semi-finished product after the initial molding to be taken out and sprayed with glue manually, and then put back into the mold for molding and molding together with the inner layer. The process of taking out and putting back the semi-finished product needs to be re-positioned, which not only reduces the work efficiency, but also affects the positioning accuracy in the entire molding process and affects the yield rate. In addition, there are errors in manual spraying, which does not have standard operability.

[0045] Aiming at the defects of the prior art, the utility model provides a one-piece bra, Figure 1-2 As shown, the one-piece bra includes a bra body, a cup cotton layer 1 and a shoulder strap 2. The bra body is a one-piece structure, having a cup portion 100, a lower portion 200, a side portion 300, a rear portion 400 and a transition portion 500 extending beyond the edge of the cup cotton layer. The bra body is formed by a bra surface layer 3 and a bra inner layer 4 of the same shape being bonded to each other, and the cup cotton layer 1 is bonded and fixed between the bra inner layer 4 and the bra surface layer 3.

[0046] The cup cotton layer 1 is a one-piece structure, which is formed by cutting and molding a piece of sponge, and includes a cup area 11, a lower pick area 12 and a side ratio area 13 corresponding to the cup part 100, the lower pick part 200 and the side ratio part 300 respectively. Arranging the cup cotton layer 1 at the lower pick part 200 and the side ratio part 300 of the bra can improve the supporting performance and stability of the bra.

[0047] The thickness of the cup cotton layer 1 gradually decreases from the nipple point to the edge of the cup cotton layer 1, and smoothly transitions to the transition portion 500. The design of gradually thinning the cup cotton layer 1 can avoid the molded rear lower stripping area 12 and the front edge being too thick, making it more comfortable to wear.

[0048] The back portion 400 of the bra surface layer 3 and the bra lining 4 includes a connection area, which is provided with a little glue or a film. Only the bra surface layer 3 and the bra lining 4 in the connection area of ​​the back portion 400 are fitted and fixed, which can better ensure the elasticity of the back portion 400 and improve the stability of the bra when worn.

[0049] In one embodiment, the bra surface layer 3 and the bra inner layer 4 are both cut from a single layer of elastic fabric, and the weight of the elastic fabric is 100-300 g / m 2The content of spandex is 15-60%. It has a light texture, good elasticity, and is more comfortable and breathable to wear. It can improve wearing stability, avoid relaxation and deformation, and affect service life.

[0050] In a specific embodiment, the cup cotton layer 1 has a thickness of 5-25 mm, gradually becoming thinner from the nipple point to the edge, and smoothly connected with the transition part 500, which can not only effectively cover the nipple point, but also prevent the cup part 100 and the lower part 200 from being too thick and heavy, affecting the wearing comfort and support performance.

[0051] In one embodiment, the one-piece bra also includes a cup pad layer 5 that is fitted and fixed between the cup cotton layer 1 and the bra inner layer 4. There are two cup pad layers 5, corresponding to the left and right cups respectively. The cup pad layer 5 mainly covers the nipple points. When the bra has a design requirement of being light, thin and breathable, a thinner cup cotton layer 1 is generally designed, such as a thickness of 5-10mm. In order to avoid wearing convex points, a cup pad layer 5 is added to the nipple points so that the bra can avoid the embarrassment of convex points while ensuring breathability. Furthermore, a punched sponge can also be selected as the cup cotton layer 1 to ensure that the bra product is more breathable. In other embodiments, a combination of sponge and upright cotton can also be selected to produce the cup cotton layer 1.

[0052] In a specific embodiment, the width of the transition portion 500 is not less than 3 mm, and the width of the transition portion 500 refers to the distance between the edge of the cup cotton layer 1 and the edge of the corresponding part of the bra body. The design of the transition portion 500 can make the edge of the bra fit the human skin more closely, and the wearing is more fit and seamless, and can effectively wrap the chest to prevent the chest from overflowing or the lower part 200 from bulging.

[0053] The bra surface layer 3 and the bra inner layer 4 of the rear ratio part 400 are connected only through the connection area. In one embodiment, the connection area is located at the upper and lower binding positions of the rear ratio part 400, the upper binding position of the bra surface layer 3 corresponding to the rear ratio part 400 and the upper binding position of the bra inner layer 4 corresponding to the rear ratio part 400 are fitted and fixed, the lower binding position of the bra surface layer 3 corresponding to the rear ratio part 400 and the lower binding position of the bra inner layer 4 corresponding to the rear ratio part 400 are fitted and fixed, and the remaining positions are not fixed, which can maintain the original elastic effect and softness of the fabric and provide wearing comfort. Specifically, the bra surface layer 3 and the bra inner layer 4 of the rear ratio part 400 can be connected by sewing or local film technology, and can also be connected by glue dispensing technology. When the glue dispensing technology is used for connection, the position where the glue point is set is the connection area.

[0054] In a specific embodiment, the one-piece bra also includes a soft steel ring 6 and / or a bone 7 that is fitted and fixed between the cup cotton layer 1 and the bra inner layer 4. The soft steel ring 6 is located at the bowl ring position of the one-piece bra, which can improve the support performance of the bra. The bone 7 is located at the junction of the side ratio part 300 and the back ratio part 400 of the one-piece bra, which can provide stability for the bra. Those skilled in the art can selectively design the soft steel ring 6 and the bone 7 according to design requirements, and this application does not make specific restrictions. In addition, auxiliary materials such as heart cloth and side ratio cloth can be directly set on the cup cotton layer 1 and the bra inner layer 4 to improve the support performance and stability of the bra.

[0055] It should be noted that Figure 1 The bra styles shown are for illustrative purposes only, and the specific styles of the bras are not limited in this application. The height of the side wall portion 300, the coverage area of ​​the cup portion 100, etc. can be adjusted according to design requirements. The bras can be designed to be higher than the side, a three-quarter cup style, a small vest style, etc.

[0056] Another embodiment of the utility model provides a molding die for making the one-piece bra, combined with Figure 3-6 As shown, it includes a first mold 600, a second mold 700 and a third mold 800. The first mold 600 and the second mold 700 are male molds, and the third mold 800 is a female mold.

[0057] like Figure 3 As shown, the first mold 600 and the third mold 800 are openably connected by snapping, the first mold 600 includes a first molding surface 6001, the third mold 800 includes a third molding surface 8001, the first mold 600 and the third mold 800 are snap-connected, and a first molding cavity is formed between the first molding surface 6001 and the third molding surface 8001. The first mold 600 and the third mold 800 are used to perform preliminary molding on the bra surface layer 3 and the cup cotton layer 1, so that the bra surface layer 3 and the cup cotton layer 1 present the prototype of the bra.

[0058] The second mold 700 and the third mold 800 are openably buckled and connected, and the second mold 700 includes a second molding surface 7001. The second mold 700 and the third mold 800 are buckled and connected, and a second molding cavity is formed between the second molding surface 7001 and the third molding surface 8001. The first mold 700 and the third mold 800 are used to mold and press the bra surface layer 3 and the cup cotton layer 1 having the shape of a bra, and the bra inner layer 4 to obtain a finished bra.

[0059] When forming the first molding cavity, the distance between the first molding surface 6001 and the third molding surface 8001 is greater than the distance between the second molding surface 7001 and the third molding surface 8001 when forming the second molding cavity, so as to form the desired thickness and shape by step molding.

[0060] In a specific embodiment, the second molding surface 7001 and the third molding surface 8001 are curved surfaces that match the inner and outer surfaces of the cup portion 100 of the one-piece bra.

[0061] In one embodiment, the third mold 800 is driven by a linear drive pair (not shown in the figure), and can directly reciprocate at positions corresponding to the first mold 600 and the second mold 700, so as to be buckled and connected with the first mold 600 and the second mold 700, respectively. After the initial molding, there is no need to take out the semi-finished product, and the automatic glue spraying or the laminating operation on the inner layer of the bra is directly performed, and then the inner layer 4 of the bra is placed on the third mold 800, and the third mold 800 is moved to the position corresponding to the second mold 700, and is buckled and connected with the second mold 700 for molding molding. Multiple positioning in the molding process is avoided, positioning accuracy is guaranteed, and process steps are saved, thereby improving work efficiency and ensuring the yield rate.

[0062] In a specific embodiment, the third mold 800 also includes a lower pick-up concave position 8002 and a side ratio concave position 8003 to mold the lower pick-up portion 200 and the side ratio portion 300. The first mold 600 includes a first lower pick-up convex position 6002 and a first side ratio convex position 6003 that respectively match the lower pick-up concave position 8002 and the side ratio concave position 8003 to perform initial molding on the area corresponding to the cup cotton layer of the bra; the second mold 700 includes a second lower pick-up convex position 7002 and a second side ratio convex position 7003 that respectively match the lower pick-up concave position 8002 and the side ratio concave position 8003 to perform molding on the area corresponding to the cup cotton layer of the bra. The molding mold only performs hot pressing molding on the cup portion 100, the lower pick-up portion 200 and the side ratio portion 300, which can reduce the molding time and molding range, and reduce the structural damage to the fabric and sponge caused by long-term high-temperature molding. After the molding is completed, the bra surface layer 3 and the bra inner layer 4 of the rear portion 400 are connected separately, which can maintain the original elastic effect and softness of the fabric and improve the wearing comfort and stability.

[0063] In one embodiment, the first mold 600 and the second mold 700 are designed as one body. In another embodiment, the first mold 600 and the second mold 700 are designed as separate bodies.

[0064] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
