    • A blank for a paperboard container is provided on one of its surfaces with a layer of food-contacting polymethylpentene. The container formed from the blank, as by bending the blank along fold lines, requires one or more overlapped joints such as the usual manufacturer's joint. To overcome the non-stick properties of the polymethylpentene layer, the layer is flame treated so that it will adhere to a conventional water based, FDA approved adhesive and thereby make possible the formation of a seam or other overlapped joint or joints. Flame treatment is restricted to portions of the area of the polymethylpentene layer that are involved in the formation of the overlapped joint or joints. Alternatives to flame treatment include corona treatment, solvent treatment or treatment of the polymethylpentene surface with a solvent based primer.
    • 在其一个表面上设置有一层与食品接触的聚甲基戊烯的纸板容器坯料。 由坯料形成的容器,通过沿着折叠线弯曲坯料,需要一个或多个重叠的接头,例如通常的制造商的接头。 为了克服聚甲基戊烯层的不粘性,将该层进行火焰处理,使其粘附到常规的水基FDA批准的粘合剂上,从而可能形成接缝或其它重叠​​接头或接头。 火焰处理限于涉及形成重叠的接头或接头的聚甲基戊烯层的区域的部分。 火焰处理的替代方法包括电晕处理,溶剂处理或使用溶剂型底漆处理聚甲基戊烯表面。

    • Disclosed is a process for the molding of hollow articles such as full length Foley catheters. The apparatus preferably comprises a mold with two lumen forming wires longitudinally disposed therein. A set of two receiving wires are spaced distally from the distal ends of the lumen forming wires and are longitudinally aligned therewith. A first follower is slidably disposed about the lumen forming wires in close abutment with the wires and inside wall of the mold. The first follower is preferably disposed toward the proximal end of the mold and preferably at least two other followers are provided spaced distally of the first follower. One of the other followers preferably bridges the space between the lumen forming wires and receiving wires. Sets of gates are preferably provided along the length of the mold in fluid communication with a source of molding material. In practice, molding material is injected into the molding channel at the proximal end of the mold and flows longidutinally toward the distal end of the mold while pushing the first follower along the wire ahead of it. As the follower proceeds toward the distal end of the mold, it engages and pushes the remaining followers toward the distal end of the mold. At the beginning of the molding process, each set of gates has a follower that is transversely aligned with it so as to seal the set of gates and prevent the flow of molding material through the set of gates and into the mold. In this fashion, molding material is not introduced through a set of gates and into the mold until all followers are distally located from the set of gates.
    • 公开了一种用于模制中空制品如全长Foley导管的方法。 该装置优选地包括具有纵向设置在其中的两个内腔形成丝的模具。 一组两个接收线从内腔形成线的远端向远侧间隔开并与其纵向对准。 第一跟随器可滑动地布置在管腔周围,与金属丝和模具的内壁紧密邻接。 优选地,第一随动件朝向模具的近端设置,并且优选地,至少两个其它从动件被设置成与第一跟随件向远侧隔开。 其他追随者之一优选地桥接管腔形成线和接收线之间的空间。 浇口组优选地沿模具的长度设置成与模制材料源流体连通。 在实践中,模塑材料在模具的近端被注入模制通道中,并且沿着模具前端的线推动第一跟随器,沿着模具的远端朝向模具的远端流动。 当跟随者朝着模具的远端行进时,其接合并将剩余的追随者推向模具的远端。 在模制过程开始时,每组门具有与其横向对准的跟随器,以便密封该组门,并防止模制材料流过该组门并进入模具。 以这种方式,成型材料不通过一组浇口引入模具中,直到所有追随者远离该组门。
