Definitions

  • the present invention relates to a paper container for holding a high-temperature liquid such as juices and wines which are to be circulated at ambient temperature, and to a method for filling the container with contents and sealing it.
  • the paper container of the present invention comprises a cylindrical body consisting mainly of a paper sheet, on at least an inner surface of which is formed a thermoplastic synthetic resin layer; and a lid plate and a bottom plate which are formed to seal openings at the upper and lower ends of the body.
  • Each plate may comprise a paper sheet, a thermoplastic synthetic resin sheet, a metal foil layer or a laminated body thereof.
  • this technique can prevent the deformation satisfactorily for a small container, it fails to do so for a large container.
  • the closing device (lid) cannot absorb all the deformation and the container is still deformed into an irregular shape.
  • a flexible backing member as a means for preventing deformation of the container due to the pressure difference is arranged along the inner surface of a tubular body.
  • the backing member is fixed at both ends of the tubular body and is left unfixed along its intermediate length. Therefore, the backing member can deform inward independently of the tubular body. However, since a gap is then defined between the tubular body and the backing member, the cooling characteristics of the contents after high-temperature filling are not good. Furthermore, the backing member may become separated from the tubular body upon inward deformation, but this may not be detected from the outside.
  • at least a plurality of linear creases extend toward the openings and are so distributed around the circumference as to provide for regular inward deformation of the body when the internal pressure reduces to a negative value.
  • arc-shaped or slanted linear creases extend continuously from the upper and lower ends of adjacent linear creases. From the commencement of filling the container with the high-temperature contents to the time of sealing it with a lid, body portions between the creases are uniformly pressed toward the central axis of the body, forming the body into a polygonal prism shape before being sealed and allowing the contents to cool.
  • the present invention provides a paper container for holding a high-temperature liquid and a method for filling the container with the high-temperature liquid wherein the upper and lower ends of the cylindrical container have circular sections while the body has a polygonal section.
  • the side surfaces of the container have a polygonal section.
  • the container may not deform into an irregular shape.
  • linear creases 1 extend in a cylindrical body to define dihedral angles.
  • Arc-shaped or slanted linear creases 3 extend continuously from both ends of the creases 1. These creases 1 and 3 together define the side surfaces 2 of the polygonal section.
  • the creases 1 which define the dihedral angles of a polygon extend linearly for a suitable length.
  • the arc-shaped or slanted linear creases 3 for regular deformation are formed continuously from both ends of the creases 1, that is, at the upper and lower parts of the polygon side surfaces 2.
  • the creases 3 may be discontinuous at the tops thereof.
  • Adhering parts 4 are formed at both ends of the developed body; the adhering parts 4 at both ends of the developed body have contiguous creases 3. The adhering parts 4 are adhered together to form a body of cylindrical shape, as seen in Fig. 4.
  • a bottom 6 as shown in Fig. 3 is adhesively joined to the body.
  • the container After filling the container with a heated soft drink or the like, the container is sealed with a lid 5 consisting mainly of an aluminium foil layer.
  • a negative pressure is established inside after the container is filled with the heated contents and is sealed and cooled.
  • the side surfaces 2 shown in Fig. 2 deform inwardly; the original shape of the container is substantially maintained by reason of the regular inward deformation of the side surfaces 2 between the creases 1 and 3.
  • the negative pressure of the container is moderated by this regular inward deformation of the side surfaces 2, so that, as a whole, the outer shape of the container is maintained i.e. does not deform irregularly.
  • Figs. 5 to 8 show an apparatus for filling the container of the present invention with a liquid.
  • the apparatus comprises a container holder 8 with a recess 7 of the same shape and dimensions as those of a cylindrical container C having the creases 1, and press rollers 9 which are arranged around the container C and which number the same as the side surfaces of the container defined by the creases 1.
  • Each press roller 9 is rotatably mounted on the upper end of a lever 11 which is, in turn, pivotal about a support 10 arranged midway down the outer wall of the container holder 8.
  • a roller 14 is arranged at the lower end of the lever 11 and is in contact with a vertically movable annular cam 13 which has an inclined surface 12 formed at the lower part of the outer surface of the container holder 8.
  • Openings 15 which are the same in number as the press rollers 9 are formed in the wall of the container holder 8 so that the press rollers 9 are able to move toward and away from the body of the container C.
  • the filling method will now be described in detail with reference to the apparatus as described above.
  • the container C with the creases 1 and 3 is placed within the recess 7 of the container holder 8. Since the cam 13 is located at the lower position, the press rollers 9 are withdrawn and the body is still in a cylindrical shape.
  • the cam 13 begins to be raised by an air cylinder (not shown). Then, the rollers 14 are brought into contact with the inclined surface 12 of the cam 13 to pivot the levers 11 inwardly (toward the body of the container) about the supports 10.
  • the press rollers 9 at the top ends of the levers 11 then press the side surfaces 2 of the container C defined by the creases 1 and 3.
  • This pressing procedure is continuously performed during the ascending movement of the cam 13 which is synchronous with the ascending movement of the container C from the time of filling the container with the liquid to the time of completing adhesion of the lid (not shown).
  • the side surfaces 2 of the body are pressed inward to the positions indicated by 2' by 2 to 3 mm.
  • a prism body (of a heptagonal section in this embodiment) having the creases 1 producing dihedral angle parts is formed (Figs. 9 and 10).
  • the container of the present invention Since the container of the present invention has the configuration as described above, the negative pressure inside the container after filling the container with the liquid, sealing and cooling does not result in an irregular deformation of the body, owing to the creases defining the dihedral angles. The body only deforms regularly at the side surfaces defined by the creases. Therefore, the container of the present invention has a good appearance, increasing the commercial value of the product. Furthermore, if the container is made of a laminated body including an AI or PE film, the container can withstand storage over a long period of time and allows vending by an automatic vending machine. The present invention thus provides a paper container for holding a liquid which is relatively inexpensive.
  • the container may not have a regular polygonal sectional shape.
  • the side surfaces 2 of the body are uniformly pressed inward by the press rollers to have a polygonal sectional shape from the commencement of filling the container with the contents to the time of adhering the lid.
  • the container of the present invention will have a regular polygonal sectional shape.
  • the body of the container deforms regularly as a result of the suction force resulting from the pressure difference between inside and outside the container upon cooling the high-temperature liquid contents. Therefore, a special lid need not be used; a general lid (a paper sheet, a metal layer, a thermoplastic synthetic resin film or a laminated body thereof) which is not required to have a structure to absorb deformation due to pressure difference may be used.
