Description

一种下碗部掏空杯及下碗部掏空连体杯 技术领域
本申请涉及女性内衣技术领域，尤其是涉及一种下碗部掏空杯及下碗部掏空连体杯。
背景技术
文胸是女性日常生活中不可缺少的用品之一，随着现在技术的发展，越来越多的种类的文胸被研制出来，如透气性好的文胸、穿戴舒适的文胸和抗菌的文胸等，满足不同女性的需求。
文胸一般是由罩杯与肩带连接而成，而文胸最重要的部分是罩杯，罩杯与胸部的贴合度很大程度上决定了女性穿戴文胸的舒适度。而目前市场上的罩杯制成的文胸，当女性的手臂向上抬时，肩部的活动会引起肩带的活动，肩带受到向上的力，从而带动罩杯向上移动，导致跑杯，使得罩杯不贴合胸部，造成穿戴不舒适。
实用新型内容
为了改善女性抬手时，文胸跑杯的问题，本申请提供一种下碗部掏空杯。
第一方面，本申请提供的一种下碗部掏空杯，采用如下的技术方案：
一种下碗部掏空杯，包括罩杯，所述罩杯分为上碗部和下碗部一体成型，所述下碗部延伸设置有下扒部，所述下碗部与所述下扒部连接处间隔设置有若干个透气切口。
当女性向上抬手臂时，罩杯在肩带的牵扯作用下，向上滑动，与胸部不贴合，且当女性向下回收手臂时，罩杯难以退回到合适的位置，罩杯难 以与胸部完全贴合，对胸部产生压迫，为了使罩杯归位，需要对罩杯的进行调整，比较麻烦，对此，本申请通过下碗部与下扒部连接处间隔设置有若干个透气切口，形成一个缓冲区域，使得当女性向上抬手臂时，罩杯能与胸部完全贴合，从而减少跑杯的现象。当向上抬手臂使肩带动上碗部和下碗部向上运动，透气切口发生变形，形成缓冲区，由于缓冲区使下碗部与下扒部分隔开，导致下碗部对下扒部的牵扯力小于下扒部与胸部接触的摩擦力，下扒部能稳定地与胸部贴合，从而可有效的减少跑杯的现象，同时可使杯体容量可扩充覆盖多一个码数，从而提高穿戴的舒适度。另外透气切口可提高罩杯的透气性，使胸部保持干爽的状态，实用性高。
可选的，所述透气切口的宽度为4-10mm。
若透气切口的宽度低于4mm,则向上抬手臂时，透气切口形成的缓冲区域面积小，使得下碗部对下扒部的牵扯力大于下扒部与胸部接触的摩擦力，当手向上抬起时，下扒部向上移动，容易导致跑杯；若透气切口的宽度高于10mm,则向上抬手臂时，透气切口形成的缓冲区域面积大，使得下碗部对下扒部的牵扯力小于下扒部与胸部接触的摩擦力，透气切口难以恢复原状，不利于罩杯与胸部的贴合，使得穿戴文胸不舒适。
可选的，所述透气切口的形状为弧线形、间断式弧线形、锯齿形、波浪形或菱形。
通过采用上述技术方案，使得透气切口形成的缓冲区域面积大，且缓冲区域的面积的形状改变灵活度高，当手向上任何一个方向抬起，缓冲区域的形状可随时手臂方向的变化而变化，减少跑杯现象的发生；同时增加罩杯的透气性，便于汗水的排出，减少罩杯内细菌滋生，保持罩杯干净、 干爽，提高穿戴的舒适性。
可选的，所述上碗部、所述下碗部和所述下扒位由外到内依次均包括复合层和第一布层，所述复合层与所述第一布层粘接，所述复合层远离所述第一布层的一面与外衣接触，第一布层远离所述复合层与胸部接触，所述透气切口设置于所述复合层并贯穿所述复合层。
通过采用上述技术方案，制得的罩杯轻薄、且透气性好，当透气切口发生形变时，第一布层与胸部贴合，使得手运动的过程中罩杯能稳定地与胸部贴合，从而减少跑杯的现象，第一布层与复合层连接，第一布层对复合层有牵扯力，可使形变的透气切口快速恢复原状，从而使罩杯能与胸部贴合更加稳定。
可选的，所述第一布层为弹力布层。
通过采用上述技术方案，使得罩杯在拉扯的过程中不易变形，弹力布具有良好的弹性，当手抬起，弹力布在肩带的带动下发生形变，同时透气切口也发生形变，使得下扒部能过稳定的与胸部稳定接触，不跑杯，拉扯之后能迅速地还原，维持罩杯的形状。
可选的，所述复合层依次包括第二布层、第一海绵层、第二海绵层，所述第一海绵层与所述第二布层连接，所述第二海绵层与所述第一布层连接。
通过采用上述技术方案，制得罩杯厚度薄，透气、舒适度和柔软等性能提高，海绵层具有多孔结构，便于吸汗排湿，减少闷热感。
可选的，所述复合层还包括定型网，所述定型网设置于所述第一海绵层和第二海绵层之间。
定型网的质地硬且不易变形，使得罩杯长时间使用而不变形，与第一海绵层和第二海绵层压合定型后，第一海绵层和第二海绵层质地软，难以定性，定型网对第一海绵层和第二海绵有支撑作用，可长时间支撑第一海绵层和第二海绵层，维持罩杯不变形。
可选的，所述第一布层与所述第二海绵层之间设置有用于粘接的热熔胶膜，所述第一布层与所述第二海绵层之间设置有用于粘接的热熔胶膜，所述热熔胶膜为TPU膜、PA膜或EVA膜中的其中的一种。
通过采用上述技术方案，使得第一布层与第二海绵层粘接牢固，TPU膜、PA膜或EVA膜质地柔软、透气性好、粘性好、耐水洗，通过TPU膜、PA膜或EVA膜进行热粘接的罩杯，不闷热且排湿效果好，同时经过多次水洗后，第一布层与第二海绵层能稳定连接。
第二方面，本申请提供一种下碗部掏空连体杯，采用如下技术方案：
一种下碗部掏空连体杯，所述连体杯包括连接部和两个对称设置的下碗部掏空杯，两个所述下碗部掏空杯和所述连接部一体成型；所述下碗部掏空杯为上述第一方面所述的下碗部掏空杯。通过采用上述技术方案，制得的内衣透气，不闷热且排湿效果好，罩杯能与胸部完全贴合，从而减少跑杯的现象，进一步提高穿着舒适度。
综上所述，本申请至少包括以下有益技术效果：
1.本申请通过下碗部与下扒部连接处间隔设置有若干个透气切口，形成一个缓冲区域，使得当女性向上抬手臂时，罩杯能与胸部完全贴合，从而减少跑杯的现象。
2.透气切口的形状弧线形、间断式弧线形、锯齿形、波浪形或菱形， 使得透气切口形成的缓冲区域面积大，且缓冲区域的面积的形状改变灵活度高，当手向上任何一个方向抬起，缓冲区域的形状可随时手臂方向的变化而变化，减少跑杯现象的发生；同时增加罩杯的透气性，便于汗水的排出，减少罩杯内细菌滋生，保持罩杯干净、干爽，提高穿戴的舒适性。
3.通过采用本申请的一种掏空连体杯，制得的内衣透气，不闷热且排湿效果好，罩杯能与胸部完全贴合，从而减少跑杯的现象，进一步提高穿着舒适度。

实施例2
一种下碗部掏空连体杯，参照图8，该连体杯包括连接部和两个对称连接的下碗部掏空杯，两个下碗部掏空杯和连接部一体成型，掏空杯下碗部靠近连接部8的一侧连接有支撑部位9，支撑部位9安装有TPU胶条，TPU胶条位于第一海绵层和第一布层之间，其他实施例中可以为材质柔软的EVA条、TPU条或PA条，用于替代传统的钢圈，起到支撑胸部的作用，同时质地柔软与肌肤有更好的贴合度。
本申请实施例一种掏空连体杯的实施原理为：先将第二海绵层3、定型网层4、第一海绵层2和第二布层5依次平铺，定型网层4的宽度为第 二布层5的一半，放置于下碗部，将TPU胶条放置于第一海绵层和第一布层之间，且位于下碗部边缘，再通过一体压合定型模具进行压合定型，得到连体杯，再进行切割得到透气切口6，再将EVA膜放置于与第二海绵层3与第一布层1之间，再通过热压的方式，使EVA膜熔融，将第一布层1与第二海绵层3粘接，最后进行剪裁。
以上均为本申请的较佳实施例，并非依此限制本申请的保护范围，故：凡依本申请的结构、形状、原理所做的等效变化，均应涵盖于本申请的保护范围之内。
