    摘要： A process for forming, handling, circumferentially sealing, and inverting a thin plastic half bag to an inwardly tapered, continuous inner side wall of an outer plastic container. A non-metallic mandrel is used as a tool for thermoforming a half bag over the top of the mandrel. The top of the mandrel with bag attached is inserted into an open end of the outer plastic container. A continuous metal ring connected at the circumference of the mandrel, positioned near the open end of the half bag, wedges the bag against the tapered inner side wall of the container near the midpoint of the container to form a sealing interface therebetween. A magnetic induction field generated near the container heats the metal ring on the mandrel. Heat is conducted to the sealing interface to weld the bag to the container. After the field is removed and the metal ring cools, the mandrel with metal ring is withdrawn from the thin plastic bag. Vacuum applied to the closed end of the bag from the top of the mandrel causes the bag to be inverted to the open end of the container as the mandrel is withdrawn.

    摘要： A process for forming, handling, affixing, and inverting a thin plastic half bag to a continuous inner side wall of an outer plastic container. A non-metallic mandrel is used as a tool for thermoforming a half bag over the top of the mandrel. The top of the mandrel with bag attached is inserted into an open end of the outer plastic container. A continuous stripe of heat-activated adhesive containing metal particles is bonded to the exterior of the half bag at the open end of the half bag. When the half bag is inserted, the stripe of adhesive is positioned near the midpoint of the container. A magnetic induction field generated near the container midpoint heats the metal particles in the heat-activated adhesive, thereby activating the adhesive. When the adhesive has been heated, compressed air is blown from the mandrel to press the bag and adhesive against the inner side wall of the outer container to cause bonding between them. After the field is removed and the adhesive cools, the mandrel is withdrawn from the thin plastic bag. Vacuum applied to the closed end of the bag from the top of the mandrel causes the bag to be inverted to the open end of the container as the mandrel is withdrawn.

    摘要： A squeezebottle dispenser having an inner flexible bag containing a viscous fluid in fluid communication with a dispensing nozzle. A vent hole is provided in the squeezebottle side wall which is blocked by the user to prevent air from exiting the squeezebottle during squeezing so that air compression within the squeezebottle forces the inner bag to discharge its contents through the dispensing nozzle. When the squeezebottle is released, the vent hole is unblocked in order to vent air into the squeezebottle so that the squeezebottle may return to its unsqueezed shape. The vented air entering an air space located between the squeezebottle and the inner bag replaces the volume of the contents discharged from the inner bag. The addition of a recessed channel, formed between the vent hole and a venting point, which is covered with a compliant film to form an air passage, enables the user to block the vent hole indirectly. When the compliant film is pressed into and against the recessed channel anywhere along the air passage, air cannot escape from inside the squeezebottle, thereby enabling air compression to occur inside the squeezebottle.

    摘要翻译： 挤奶机分配器具有内部柔性袋，其包含与分配喷嘴流体连通的粘性流体。 在挤压瓶侧壁中设置有通气孔，该通气孔被使用者阻挡以防止空气在挤压过程中离开挤压机，使得挤压机内的空气压缩迫使内袋通过分配喷嘴排出其内容物。 当挤压瓶被释放时，通气孔被打开以便将空气排放到挤压瓶中，使得挤压瓶可能返回到其未挤压的形状。 进入挤压机和内袋之间的空气空间的通风空气取代了从内袋排出的内容物的体积。 在通气孔和通气点之间形成的凹陷通道的添加，其被柔性膜覆盖以形成空气通道，使得使用者能够间接地阻塞通气孔。 当沿着空气通道将顺应性膜压入和靠着凹陷通道时，空气不能从挤压机内部逸出，从而使得能够在挤压机内发生空气压缩。
