专利内容由知识产权出版社提供专利名称：DOUBLE COUPLER NOZZLE FOR PIPINGBAGS AND STANDS THEREFOR发明人：FOLKMAR, Jan申请号：IB2015/001450申请日：20150325公开号：WO2016/079579A1公开日：20160526专利附图：摘要：A double coupler nozzle system for sealing to a pair of flexible film bags (or toa double bag, i.e. three triangles of film welded down the diagonals or a single piping bagwhich has been welded down the length) having a wider upper end and a conical lowerend with an opening for flowable material inside the bag and for expressing the flowablematerial. The system comprises a pair of hollow nozzle bases (20a, 2b) each having anexterior wall and an interior wall (35a, 35b, 36a, 36b) and being coupled together alongthe interior walls (35a, 35b, 36a, 36b). The exterior wall of each nozzle base form aportion of a substantially right circular truncated cone with a larger diameter end (42)and a smaller diameter end (44) and cut along a plane containing the longitudinal axis ofthe cone, the interior wall (35a, 35b, 36a, 36b) of each nozzle base being non-planar andspanning edges of the exterior wall to form an inlet opening adjacent the nozzle baselarger diameter end (42) and an outlet opening adjacent the nozzle base smallerdiameter end (44), the nozzle base interior walls (35a, 35b) extending inward or outward,or male/female, and complimenting each other when the bases are coupled togetheralong the interior walls. Each of the nozzle bases (20a, 20b) are adapted to be receivedsnugly within the conical lower end of one of the bags with the film of the lower end ofthe bag extending over the exterior and interior walls of the nozzle bases and having alower bag edge ending intermediate the larger (42) and smaller diameter ends (44) ofthe nozzle base (20a, 20b), and having film of the bags between the respective interiorwalls of the coupled nozzle bases (20a, 20b). The coupled nozzle bases permit side-by-side simultaneous flow of material from bags sealed to the nozzle bases and out of theoutlets of the coupled nozzle bases.申请人：FOLKMAR, Jan地址：Buhlstrasse 12 CH-6353 Weggis CH国籍：CH更多信息请下载全文后查看
