  Embodiments of the present invention will be described with reference to the drawings.

First, the structure of the packaging container 100 of embodiment of this invention is demonstrated. FIG. 1 is an exploded perspective view of a packaging container 100 according to an embodiment of the present invention. As shown in FIG. 1, the packaging container 100 includes a container main body 1 provided with an opening and a lid member 2 that covers the opening of the container main body 1. The container body 1 has a bottom part and a side part, and constitutes an outer edge part 11 at the upper end of the side part.
An example of the container body 1 is a truncated cone shape having a disk-shaped bottom and side portions.

  The lid member 2 has a lower sheet 22 bonded to the outer edge portion 11 of the opening of the container body 1 and an upper sheet 21 laminated on the lower sheet 22. The upper sheet 21 is a laminate of a resin film and a laminate of one or both of paper and resin (hereinafter referred to as “upper intermediate layer”). The lower sheet 22 is a laminate of a resin film, a laminate of one or both of a paper and a plastic film (hereinafter referred to as “lower intermediate layer”, and a sealant). The lower intermediate layer may include a light shielding layer.

  FIG. 2 is a plan view of the upper sheet 21, and FIG. 3 is a plan view of the lower sheet 22. As shown in FIGS. 2 and 3, the lid member 2 includes a first tab 2d, a second tab 2e, and a third tab 2f connected to the outer edge. The lid member 2 includes a strip-shaped first peeling region 2a that crosses the lid member 2, and a non-peeling region 2b and a second peeling region 2c that sandwich the first peeling region 2a.

  In the lid member 2, the first tab 2d is provided at a part of the outer edge in the non-peeling region 2b, and the second tab 2e is provided so as to be connected to one outer edge of the first peeling region 2a. The third tab 2f is connected to the outer edge of the second peeling region 2c and the second tab 2e. In the upper intermediate layer, perforations 2m are provided at the boundary between the first peeling region 2a and the non-peeling region 2b and at the boundary between the first peeling region 2a and the second peeling region 2c. Further, the cover member 2 is formed with two cuts 2h extending from the vicinity of each end of the perforation 2m on the side where the second tab 2e is provided so as to increase the distance from each other. At that time, it is preferable that one end of each cut 2h is formed in the vicinity of the center of each end of the perforation 2m. Thereby, when the 2nd tab 2e is picked and the strip-shaped 1st peeling area | region 2a is removed, it can peel easily and smoothly, without fracture | rupturing on the way. The outer periphery excluding the tip of the second tab 2e is formed by the cut 2h. Of the two cuts 2h, one extending from the perforation 2m formed at the boundary between the first peeling region 2a and the second peeling region 2c is also a part of the outer periphery including the vicinity of the tip of the third tab 2f. Forming part. A half cut 2j that crosses the second tab 3e and the third tab 2f is formed on the side of the lower sheet 22 at the connecting portion between the second tab 2e and the third tab 2f on the outer edge of the lid 2. Moreover, although the perforation 2m has shown the shape extended to the edge of the 2nd tab 2e in FIG. 2, it should just be connected to the edge part of the cut 2h. However, when the perforation 2m is formed to extend to the edge of the second tab 2e, there is an advantage that the perforation 2m can be formed easily and at low cost by rotary cutting or the like.

  In the non-peeling region 2b of the lid member 2, the upper sheet 21 is bonded to the lower sheet 22 in a state where it is difficult to peel off. Moreover, in the 1st peeling area | region 2a and the 2nd peeling area | region 2c of the cover material 2, it has adhere | attached in the state which can peel with the upper sheet | seat 21, the lower sheet | seat 22, and peeling varnish. In the second peeling region 2c of the lid member 2, a plurality of annular half cuts 2k are provided on the lower sheet 22 side.

  Next, an example of the usage method of the packaging container 100 of embodiment of this invention is demonstrated. Noodles for yakisoba are stored in the container body 1 of the packaging container 100.

  A user (consumer or the like) first picks up the second tab 2e, and bends and pulls it upward. As a result, the upper sheet 21 is peeled off from the lower sheet 22 with the half cut 2j as the peeling start position, and is peeled while breaking along the perforation 2m. FIG. 4 is a perspective view of the packaging container 100 in a state where the first peeling region 2 a of the upper sheet 21 is peeled from the lower sheet 22.

  Next, the user (consumer or the like) pinches the first tab 2d of the lid member 2 and bends and pulls it upward. As a result, the upper sheet 21 and the lower sheet 22 of the lid member 2 are integrally peeled from the opening of the container body 1. A user (consumer or the like) peels off the non-peeling region 2 b of the lid 2 and partially opens the packaging container 100.

  Since the upper sheet 21 is peeled from the first peeling region 2a of the lid member 2, the rigidity is reduced and the dead hold property is imparted. Therefore, the state where the non-peeling region 2b of the lid member 2 is opened can be maintained. FIG. 5 is a perspective view showing a state of the packaging container 100 in this state. A user (consumer or the like) pours hot water into the container body 1 and then covers the opening of the container body 1 again with the non-peeling region 2b.

  As described above, one of the two cuts 2h forming part of the outer periphery of the second tab 2e also forms part of the outer periphery including the vicinity of the tip of the third tab 2f. Only when 2e is removed from the packaging container 100 together with the first peeling region 2a of the upper sheet 21, the entire third tab 2f is exposed as shown in FIGS.

  The user (consumer or the like) waits for the noodles for fried noodles to be heated and reheated, and then pinches the third tab 2f and bends and pulls it upward. The upper sheet 21 peels from the lower sheet 22 with the half-cut 2j as the peeling start position, and progresses while peeling along the perforation 2m. FIG. 6 is a perspective view of the packaging container 100 in a state where the second peeling region 2 c of the upper sheet 21 is peeled from the lower sheet 22.

  The area surrounded by the annular half-cut 2k formed on the lower sheet 22 side of the second peeling area 2c of the lid member 2 is detached as the upper sheet 21 is peeled off, and a hot water cutting hole appears. Put out. A user (consumer or the like) discharges the hot water inside the container main body 1 to the outside of the packaging container 100 from the hot water cutting hole.

  A user (consumer or the like) picks up the first tab 2 d of the lid member 2 and peels the entire lid member 2 from the container body 1. Thereby, fried noodles can be eaten by a user (consumer or the like).

In the lid member 2, the second tab 2 e and the third tab 2 f are adjacent to each other and defined by a single notch 2 h. Therefore, the outer periphery of the lid member 2 has a simple shape, and the possibility of manufacturing defects of the lid member 2 and the packaging container 100 can be reduced.

  In addition, by making the second tab 2e into a mushroom shape or the like whose tip greatly expands to the left and right, it is possible to prevent the second tab 2e from being unintentionally opened from the third tab 2f first. That is, while the tip of the second tab 2e is exposed from the beginning, the vicinity of the tip of the third tab 2f is used to peel the first tab 2e of the upper sheet 21 from the second tab 2e. Then, since the whole is exposed after the removal, it is possible to reduce the possibility of erroneous use procedures of the second tab 2e and the third tab 2f.

Moreover, in the 1st peeling area | region 2a of the lid | cover material 2, even if the aluminum foil is not contained in the lid | cover material 2 by the rigidity of the 1st peeling area | region 2a being reduced by peeling the upper sheet | seat 21. FIG. , Dead hold property can be imparted. Further, by not using the aluminum foil, the inside of the packaging container 100 can be inspected from above the lid material 2 using a metal detector, facilitating quality inspection, and disposal of the lid material 2 Cost can be reduced.

  An embodiment of the lid according to the present invention will be described. FIG. 7 is a diagram schematically illustrating a layer configuration in a cross section along the line AA ′ of the lid member 2 according to the embodiment.

The upper sheet 21 of the lid 2 is printed on one side of a piece of art paper (weighing 104.7 g / m ² ) with picture ink 71 (nitrified cotton + urethane system), and two perforations 2 m (“ha”). 3 rows of 5 mm-shaped cuts are formed at intervals of 2 mm, and a PET (polyethylene terephthalate) film (thickness 12 μm) having a linear cut property is laminated on the other side of one piece of art paper Has a layer structure in which a sealing varnish (urethane type) is applied. The lower sheet 22 of the lid 2 is made of LDPE (low-density polyethylene) which has been subjected to light-shielding printing 72 (urethane-based ink, three-color printing of Smith Smith) on one surface of a PET film (thickness 12 μm) whose corona treatment has been applied to both surfaces, and then extruded. , A thickness of 15 μm) is laminated, and an adhesive easy peel layer (thickness of 20 μm) made of polystyrene is laminated on the other surface of the PET film. Here, the PET film of the lower sheet 22 may be one that has been previously corona treated on both sides, or may be corona treated on both sides when the lower sheet 22 is laminated.

  The upper sheet 21 and the lower sheet 22 are bonded to each other by interposing a wax-based peeling varnish 73 in portions corresponding to the first peeling area 2a and the second peeling area 2c of the upper sheet 21, and the laminated sheet is bonded to the mold. The lid member 2 having a diameter of 180 mm is formed by punching. The lower sheet 22 is formed with a peeling start half cut 2j and an annular half cut 2k for exposing a hot water cut hole (diameter 6 mm, 15 pieces) together with punching. A cut 2h is formed from the upper sheet 21 to the lower sheet 22 at the end of the perforation 2m on the tab 2e side.

  The container body 1 is a polystyrene molding cup in which an HIPS (high impact polystyrene) film is adhered to the inner surface (the surface sealed with the lid member 2).

  When the opening operation of the second tab 2e was performed using the packaging container according to the present example, the upper sheet 21 and the lower sheet 22 were easily separated and the peelability was good, and the second tab 2e was easy to pinch, Also, the third tab 2f was not pinched first. In addition, the first peeled region and the second peeled region were not peeled off and fractured by the straight cut PET on the outermost layer that was not machined. Next, when the opening operation of the first tab 2d was performed, even when the cover material 2 was peeled up to the part of the peeling varnish 73, it was folded completely well up to a folding angle of 180 °, and the unsealed state was maintained. It was confirmed that even if it was conducted, it had a good dead hold property. Finally, when the opening operation of the third tab 2f was performed, it peeled off satisfactorily and a hot water cutting hole appeared, and the hot water cutting property was also good.

  Furthermore, since the lid member 2 according to the present example does not contain aluminum, the internal inspection of the packaging container using a metal detector could be performed without any problem.

  The present invention is useful for a packaging container in which food or the like is stored.
