发明名称 Pouch with pre-inserted straw
摘要 A pouch for holding liquids includes a pre-inserted straw within the pouch. A top end of the straw is exposed by removing a portion of the pouch. For manufacture, a web of flexible packaging material, suitable for forming a pouch or bag for storing liquids, is advanced forward in a pouch forming direction. A single straw of suitable length to fit within the confines of a resulting pouch is cut from a continuous length of straw material. The single straw is placed onto the web of packaging material in a location that will be on the inside surface of a single wall of the pouch and there it is secured in place preferably by a heat seal between one side of the straw and the inside surface of the pouch wall. The resulting pouch web material, having a plurality of straws positioned along its length provides a feedstock for forming pouches with pre-inserted straws when using a so called form and fill method of forming pouches or when making pre-made pouches. The pre-inserted straw is totally enclosed within the confines of each resultant pouch and therefore eliminates the need to be attached to the outside of the pouch or be inserted into the pouch through one of the walls of the pouch.
