    Abstract: An easy-open and tamper-evident beverage container and opening system for the beverage container are provided which include a container barrier wall. The barrier wall has a series of slits therein which define a pierceable straw hole. The series of slits divides the barrier wall into a hole portion and a remainder portion, with the hole portion connected to the remainder portion by attachment points provided between adjacent slits of the series. A membrane seal is located inside of the container and sealingly covers the straw hole. This membrane seal is liquid impervious and includes (a) an outer portion which is sealed to an inside surface of the front barrier wall about the straw hole, and (b) an inner portion integral with the outer portion which is not sealed to the inside surface of the barrier wall and which covers the straw hole.

  • Patent number: 5937617
    Abstract: 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.

  • Patent number: 5934809
    Abstract: Pouches of flexible packaging material exhibit a tearing zone in the form of a weakness such as perforations or a separation in the material, this in order to be able to remove the contents easily. The packaging material is covered over by at least one film-forming mass, at least in the region of weakness, in order that the package remains closed until the contents are to be used. The film-forming mass may be the decorative printing on the pouch. After packaging, the contents are protected by the pouch and, in order to remove the contents, the pouch may be opened readily by a pulling or snapping movement which causes the covering of film-forming mass to break.
