Definitions

  • This invention relates to a tightly sealed paper container provided with a simplified opening device.
  • the lining member is bonded to the rear surface of the container formed with the opening and the pull tab piece covering the opening is secured to the top surface of the container, it is unable to reseal after the opening operation.
  • the opening device is protruded from the container, whereby the height thereof serves an obstacle, as that handling of a carton and assembling of the container on a fill-up and tight-seal device come to be complicated.
  • the opening device is of a complicated shape, so that the opening device cannot be fully exposed to a hydrogen peroxide gas at the time of sterilizing the inner surface of the container prior to fill-up of the content, or there is a possibility that the gas remains in the opening device.
  • US-A-4,770,325 describes a tightly sealed paper container having the features of the preamble of Claim 1.
  • the present invention has been developed to obviate the disadvantages of the above-described conventional opening device.
  • the invention provides a tightly sealed paper container in accordance with Claim 1.
  • the through hole formed in the container material is covered with the barrier film bonded to the rear surface of the container.
  • This barrier film is bonded to the inner surface of the coupling projection of the top board superposed on the bottom board bonded to the front surface of the container through the through hole of the container material and the through hole of the bottom board, whereby, when the top board is pulled up from the bottom board, a portion of the barrier film bonded to the inner surface of the coupling projection of the top board is cut away, so that the through hole of the container material is opened.
  • the protrusion from the container material is as very small as the combined thicknesses of the top board and the bottom board, so that there is no trouble for forming the container material secured thereto with the aforesaid opening device into a carton and handling of the carton, assembling of the container on the fill-up and tight-seal device and fill-up of the content can be performed without any trouble.
  • the container is so simple in construction that it has no pour-out tube portion, so that, at the time of sterilizing with the hydrogen peroxide gas, there are no possibilities that any portion is left unexposed to the hydrogen peroxide gas and the gas remains in the opening device.
  • a main body of paper container and 2 a container material forming the main body of paper container 1.
  • This container material 2 is formed of a laminated body in which layers 4, 5 made of thermoplastic synthetic resin such as polyethylene and polypropylene are laminated on the outermost layers of the front and rear surfaces of a paper board 3, and, as necessary, a reinforcing layer such as an aluminium foil layer and a synthetic resin layer of barrier property is laminated on a substrate thereof.
  • Denoted at 6 is a through hole formed in the container material 2 positioned at a top wall 7 of the main body of paper container 1.
  • Designated at 8 is a bottom board made of synthetic resin bonded to the front surface of the container material 2 formed therein with a through hole 6.
  • This bottom board 8 is formed therein with the through hole 9 smaller in size than the through hole 6 formed in the container material 2.
  • a raised wall 10 having substantially the same height as the thickness of the container material 2 is provided along the contour of the aforesaid through hole 9 in a tubular shape on the side of the surface of the bottom board 8, to which the container material 2 is bonded.
  • the bottom board 8 with this arrangement is bonded to the front surface of the container material 2 with the tubular raised wall 10 inserted into the through hole 6 of the container material 2.
  • the through hole 9 of the bottom board 8 bonded to the front surface of the container material 2 is positioned within the contour of the through hole 6 of the container material 2.
  • a top board made of synthetic resin superposed on the bottom board 8.
  • This top board 11 is formed with a coupling projection 12, the outer periphery of which is at least partially coupled in pressure contact into the inner wall of the through hole 9.
  • pressure contact projections 13 coming into pressure contact with the outer periphery of coupling projection 12 of the top board 11 are formed on the inner wall of the through hole 9 of the bottom board 8.
  • the present invention should not necessarily be limited to this, and pressure contact projections may be formed on the outer periphery of the coupling projection 12 of the top board 11, or the outer periphery of the coupling projection 12 of the top board 11 may be brought into pressure contact with the entire circumference of the inner wall of the through hole 9 of the bottom board 8, for example.
  • the pressure contact may be permitted to the extent where, at least, the coupling projection 12 coupled into the through hole 9 is not easily drawn out therefrom.
  • the top board 11 with this arrangement is superposed on the bottom board 8 bonded to the front surface of the container material 2 with the coupling projection 12 coupled into the through hole 9.
  • the inner surface of the coupling projection 12 of the top board 11 is exposed to the interior of the main body of paper container 1 through the through hole 9 and the through hole 6 of container material 2.
  • a barrier film 14 made of aluminum foil or the like covering the through hole 6 of the container material 2 is laminated on the rear surface of the container material 2 is bonded to the inner surface of the coupling projection 12 of the top board 11, which is exposed through the rear surface of the container material 2 and the through hole 6.
  • the upper end of the top board 11 is rockably connected to the upper end of the bottom board 8. Furthermore, the lower end of the bottom board 8 curves upwardly, whereby an apron 15 is formed to avoid saggs of liquid.
  • a ring-shaped tag 16 is provided at the lower portion of the top board 11. The shape of this tag 16 should not be limited to a specific one, and any shape easily held may be adopted.
  • the barrier film 14 may be laminated on the rear surface of the paper board 3 forming the container material 2, whereby the thermoplastic synthetic resin layer 5 having as its substrate the reinforcing layer such as the synthetic resin layer of the barrier properties is utilized as it is.
  • the present invention for opening the container, by a simple means of merely pulling up the top board from the bottom board, part of the barrier film bonded to the inner surface of the coupling projection of the top board is cut away to open the through hole of the container material, so that the container can be opened.
  • the top board which has been pulled up is superposed on the bottom board and the coupling projection of the top board is coupled into the through hole of the bottom board, so that the container can be easily resealed.
  • the protrusion from the container material is as very small as the combined thicknesses of the top board and bottom board, so that there is no trouble for forming the container material secured thereto with the aforesaid opening device into the carton, and handling of the carton, assembling of the container on the fill-up and tight-seal device and fill-up of the contact can be easily performed without requiring special reconstruction and installation of additional equipment.
  • the opening device is so simple as to have no pour-out tube portion, so that sterilizing with the hydrogen peroxide gas can be easily performed and the hydrogen peroxide gas can be easily removed after the sterilization.
  • the mechanical strength around the through hole of the container material can be reinforced with the bottom board and saggs of liquid can be prevented from occurring.
