Bag having an elastic band, and method for the production thereof
US-8556508-B2具有弹性带的袋子,用于束紧袋口。
专利摘要
袋子(1)包括弹性带(16),其通过两个连接区域(17; 2a)连接到袋子的面(1a),使得当弹性带处于静止状态时,其有效长度(L2)对应于袋子上的两个连接区域之间的空间,或小于面的纵向边缘的长度(L1)。弹性带延伸穿过袋子的整个宽度,从一个侧边缘到另一个,弹性带沿这些侧边缘焊接到袋子的两个面,至少两个连接区域之一形成位于距侧边缘一定距离处的中间连接区域(17)。
Original abstractThe bag ( 1 ) includes an elastic band ( 16 ) joined to the face ( 1 a ) of the bag by two joining areas ( 17; 2 a ) in such a manner that the useful length, when the elastic band is at rest (L 2 ), corresponds to the space between the two joining areas on the bag or is less than the length (L 1 ) of the longitudinal edge of the face. The elastic band extends over the entire width of the bag, from one lateral edge to the other, the elastic band being welded to two faces of the bag along these lateral edges, one of the at least two joining areas forming an intermediate joining area ( 17 ) located at a distance from the lateral edges.
