When using polymeric materials, thesleeve 33 may be coupled by heat welding the sleeve to the material of thecontainer body 12. Adhesive or other coupling means, such as stitching for fabric, etc., may also be used. In cases where the container body is a polymeric or thermoplastic material, a portion or portions of the container body along the walls may be pinched or drawn together and heat welded or otherwise coupled together to form the sleeve for receiving theclosure member 32. A sleeve configuration wherein the closure member may be slid within the sleeve may be beneficial for coupling the metal closure member or members to thecontainer body 12 so that the metal closure members may be removed, such as for recycling, or may be added at a stage that facilitates packaging. Although thesleeve 33 is shown with a closure member having an oval transverse cross section, thesleeve 33 may be used with closure members having other configurations as well. -
FIG. 5 shows different transverse cross sections ofclosure members flexible container 10. These may be circular, square, rectangular, oval, triangular, and a combination of these and other shapes. Hexagonal, octagonal and other polygon shapes may also be used. Theclosure members - It has been found that circular or oval cross-sectional shapes are more suitable for metal closure members, with circular being particular well suited for metal closure members. Metal closure members may have a generally uniform and continuous cross-sectional area along generally its entire length, although tapered closure members or closure members with variations in cross-sectional areas may also be used.
- The
non-metal closure member 42 ofFIG. 5 is shown provided with abody 46 having a generally circular cross-sectional shape. Theclosure member 42 is provided along one side with an outwardly projectinglip 48 that extends along the length or portions of the length of theclosure member 42. Thelip 48 may have a variety of different configurations, but is shown as being triangular or tapered in thickness towards its outermost end. A generally planar or flat lip or lips with other configurations may be used as well. The projecting lip may be used to facilitate coupling of theclosure member 42 to thecontainer body 12, as will be described later on. -
FIG. 6 shows a plan view of theclosure member 42. As can be seen, a series of notches orindentations 50 are provided in thebody 46 opposite thelip 48. Thenotches 50 may be longitudinally spaced apart at various intervals along the length of theclosure member 42. The spacing of the notches may vary, but a suitable distance may be from about ½ to about 1 inch or more apart. As can be seen, the notches orindentations 50 are formed in thebody 46 are arcuate, curved or otherwise rounded with no sharp corners. This helps minimize or prevent weakening or breakage of the closure members, which might occur if sharp angles or corners are used. If the material is sufficiently strong, however, the notches or indentations may be provided with such sharp angles or corners within the thickness of the material of thebody 46. Thenotches 50 may penetrate thebody 46 from about ⅓ to about ½ the width of thebody 46. The notches or indentations are typically provided on the non-metal or polymeric closure members to facilitate twisting and intertwining of the closure members, as is discussed later on. -
FIG. 7 shows another embodiment of aclosure member 52 havingnotches closure member 52 in a staggered configuration, wherein thenotches FIG. 8 shows aclosure member 58 withnotches FIGS. 7 and 8 are provided to facilitate twisting and intertwining of the closure members together. - Referring to
FIG. 9 , theclosure member 42 is shown coupled to thecontainer body 12. Aportion 64 of thecontainer body 12 is used to form an enclosure or sleeve for theclosure member 42 so that themember 42 is closely received and fully enclosed by the material of thecontainer body 12. In this embodiment, where are the materials are polymeric, heating welding may be used to weld theportion 64 of thecontainer body 12 to themember 42, as well as to the materials of the container body itself, such as at 66. -
FIG. 10 shows still anothernon-metal closure member 68 having a generallyrectangular body 70 with an outwardly projectinglip 72. Theclosure member 68 is coupled to thecontainer body 12 by adhesive tape layers 74 that are secured to portions of thecontainer body 12 and to opposite sides of the projectinglip 72, as is shown. - In use, the flexible container 10 (
FIG. 1 ) incorporating the closure members is opened or closed by merely twisting together or untwisting the closure members at a position adjacent to theopening 14. Portions of thecontainer body 12 are twisted along with the closure members to effectively close off theopening 14 of thecontainer 10, as shown by the arrows ofFIG. 1 . The configurations and/or materials used cause the closure members to retain their shape after twisting so that the opening of the container is effectively closed and is maintained in the closed position. Several twists of the closure members may be used to close the container. Because the closure members extend generally along the entire length of the container body, as material is removed or added to thecontainer 10 the position where the closure members are twisted together can vary generally continuously along the length of the container between theopening 14 and the material within thecontainer 10. Thus, as material is removed from thecontainer 10, the closure member may be twisted at a lower position closer to the material remaining in thecontainer 10. This minimizes the amount of space and trapped air within the flexible container. - In an alternate embodiment, the flexible container may have openings at opposite ends. Each end may be selectively closed or opened by twisting together or untwisting the closure members at a position adjacent to the openings. In this way, materials may be positioned within or removed from different ends of the flexible container.
