Description
- This invention relates to a tightly sealed paper container provided with a simplified opening device.
- As opening devices secured to tightly sealed paper containers, there have heretofore been known one in which a pull tab piece made of aluminium foil covering an opening is secured to the top surface of a container formed with the opening at a predetermined position thereof, another one in which a lining member made of synthetic resin and formed therein with a small through hole is bonded to the rear surface of the container formed with an opening at a predetermined position thereof such that the small through hole is positioned in the opening and a pull tab piece covering the opening is secured to the front surface of the container, and a further one consisting of a main body of pour-out member including a pour-out tube and a flange portion, and a cap inserted into the forward end of the pour-out tube, wherein the flange portion of the main body of pour-out member is bonded to the peripheral wall of the opening of the container.
- Out of the conventional opening devices described above, in the one in which the pull tab piece covering the opening is secured to the front surface of the container, the section of the opening is liable to be irregular in form due to torn laminated resin, whereby inconvenience is experienced with the pour-out operation and it is unable to reseal after the opening operation.
- Furthermore, in another one in which 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.
- In the last one in which the flange portion of the main body of pour-out member including the pour-out tube and the flange portion is bonded to the peripheral wall of the opening of the container, 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. Moreover, 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 top 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 top surface of the coupling projection of the top board is cut away, so that the through hole of the container material is opened.
- When the top board pulled up from the bottom board as described above is superposed on the bottom board with the coupling projection of the top board coupled into the through hole of the bottom board, the outer periphery of the coupling projection is brought into pressure contact with the inner wall of the through hole of the bottom board to be held in a coupling state, whereby the through hole which has been opened is sealed.
- 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. Further, 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.

- The present invention will hereunder be described in detail with reference to embodiments shown in the drawings.
- Referring to the drawings, designated at reference numeral 1 is 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 whichlayers 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 apaper 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 thecontainer material 2 positioned at atop 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 athrough hole 6. Thisbottom board 8 is formed therein with the throughhole 9 smaller in size than the throughhole 6 formed in thecontainer material 2. A raisedwall 10 having substantially the same height as the thickness of thecontainer material 2 is provided along the contour of the aforesaid throughhole 9 in a tubular shape on the side of the surface of thebottom board 8, to which thecontainer material 2 is bonded. Thebottom board 8 with this arrangement is bonded to the front surface of thecontainer material 2 with the tubular raisedwall 10 inserted into thethrough hole 6 of thecontainer material 2. Thus, the throughhole 9 of thebottom board 8 bonded to the front surface of thecontainer material 2 is positioned within the contour of thethrough hole 6 of thecontainer material 2. - Denoted at 11 is a top board made of synthetic resin superposed on the
bottom board 8. This top board 11 is formed with acoupling projection 12, the outer periphery of which is at least partially coupled in pressure contact into the inner wall of thethrough hole 9. In the embodiment illustrated,pressure contact projections 13 coming into pressure contact with the outer periphery ofcoupling projection 12 of the top board 11 are formed on the inner wall of thethrough hole 9 of thebottom board 8. However, the present invention should not necessarily be limited to this, and pressure contact projections may be formed on the outer periphery of thecoupling projection 12 of the top board 11, or the outer periphery of thecoupling projection 12 of the top board 11 may be brought into pressure contact with the entire circumference of the inner wall of thethrough hole 9 of thebottom board 8, for example. The pressure contact may be permitted to the extent where, at least, thecoupling projection 12 coupled into the throughhole 9 is not easily drawn out therefrom. The top board 11 with this arrangement is superposed on thebottom board 8 bonded to the front surface of thecontainer material 2 with thecoupling projection 12 coupled into the throughhole 9. Thus, the top surface of thecoupling projection 12 of the top board 11 is exposed to the interior of the main body of paper container 1 through the throughhole 9 and the throughhole 6 ofcontainer material 2. - Further, a
barrier film 14 made of aluminium foil or the like covering the throughhole 6 of thecontainer material 2 is laminated on the rear surface of thecontainer material 2 is bonded to the top surface of thecoupling projection 12 of the top board 11, which is exposed through the rear surface of thecontainer material 2 and the throughhole 6. - In this embodiment, 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 thebottom board 8 curves upwardly, whereby anapron 15 is formed to avoid saggs of liquid. Aringshaped tag 16 is provided at the lower portion of the top board 11. The shape of thistag 16 should not be limited to a specific one, and any shape easily be held may be adopted. - Incidentally, according to the present invention, the
barrier film 14 may be laminated on the rear surface of thepaper board 3 forming thecontainer 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. - As described hereinabove, according to 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 top surface of the coupling projection of the toy 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.
- Further, 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.
- Furthermore, 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.
- Moreover, 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.
