[Problems to be solved by the invention]
When preparing food packaging containers with partitions, the above two food packaging containers have a cost problem.
[0010]
According to the food packaging container 60 having the former configuration, when the food packaging container 60 having the partitioning tool 68 is manufactured, the bonding process is 1 as compared with the case of manufacturing the food packaging container not having the partitioning tool 68. The process will increase. That is, the manufacture of the food packaging container without the partitioning tool 68 only needs to have a process of bonding the cup 62 and the lid 70, while the manufacture of the food packaging container 60 with the partitioning tool 68 requires the cup 62. And a step of bonding the partitioning tool 68 and a step of bonding the partitioning tool 68 and the lid 70. Adding one bonding step is a big deal, and a significant increase in manufacturing cost is expected.
[0011]
On the other hand, according to the food packaging container 80 having the latter configuration, when manufacturing the food packaging container 80 having the stepped portion 86 or the concave portion on the side wall 88 of the main body container 82, the stepped portion or the concave portion is formed on the side wall of the main body container. Compared with the case of manufacturing a food packaging container that does not have, a processing step for forming a stepped portion or a recessed portion is added to the mold of the main body container, thereby increasing the manufacturing cost. Furthermore, if a food packaging container that does not have a stepped portion or a concave portion on the side wall can be diverted and a partition can be added, the cost of manufacturing the main body container mold can be further reduced.
[0012]
As another viewpoint, it is convenient that the partition can be used as a tray or a cup for containing a taste agent as in the above-described conventional food packaging container (see Patent Document 1).
[0013]
Accordingly, a first object of the present invention is to provide a vertical food packaging container in which a partition can be added at a low cost.
[0014]
A second object of the present invention is to provide a vertical food packaging container in which a partition can be added at a low cost, and the partition can be used as a tray or a cup.
[0015]
[Means for Solving the Problems]
In order to achieve the above first object, a vertically placed food packaging container according to the present invention includes a vertically placed outer container having an annular side wall and an upward opening formed by the side wall, and for closing the opening. An outer lid, and a partition member for vertically dividing a container internal space constituted by the outer lid and the outer container, and the side wall is substantially circular in cross section, and the cross section is from above to below. The partition member has a substantially circular partition plate having an outer diameter equal to the inner diameter of the intermediate portion in the vertical direction of the inner surface and held by the intermediate portion in the vertical direction. It is characterized by.
[0016]
In the vertical food packaging container configured in this way, when the partition plate is inserted into the outer container through the opening of the outer container and further lowered, the vertical direction in which the outer diameter of the partition plate is equal to the inner diameter of the side wall In the middle part, the partition plate is caught on the inner surface of the side wall. Thereby, a partition plate is hold | maintained and positioned in the intermediate part of a side wall. As a result, the container internal space is partitioned in the vertical direction.
[0017]
In this vertical food packaging container, it is not necessary to add an adhesion process in order to add a partition member, and it is not necessary to add a processing process for providing a stepped portion or a recess in the mold of the outer container. As a result, a partition can be added at a reduced cost. In addition, when using a vertical type outer container having an inner surface whose cross section is continuously reduced from the upper side to the lower side, which is actually used by many manufacturers, without producing the outer container mold A partition can be added. Thereby, the manufacturing cost can be further reduced.
[0018]
In this vertically placed food packaging container, the position of the intermediate portion in the vertical direction of the side wall on which the partition member is held may be changed by changing the outer diameter of the partition plate. Further, the inner surface whose cross section continuously decreases from the upper side to the lower side does not have to exist over the entire side wall. Therefore, the side wall may have a stepped portion or the like above or below the inner surface. The outer lid may be hermetically bonded to the side wall or may be fitted to the side wall.
[0019]
In this invention, Preferably, a partition member has an annular extension part extended along the inner surface of a side wall from the periphery of a partition plate.
[0020]
In the vertical food packaging container configured as described above, since the extended portion extends along the side wall, the partition member is firmly held in the middle portion in the vertical direction. Thereby, for example, it is possible to prevent the partition member from rotating in the outer container during transportation of the food packaging container. In this case, the length of the extended portion in the vertical direction is preferably 2 mm to 10 mm.
[0021]
The extended portion may extend upward from the peripheral edge of the partition plate or may extend downward.
[0022]
In the present invention, preferably, the partition plate has a central opening, and the partition member further has a tray portion that is provided in the central opening and is opposite in the vertical direction, and the tray portion extends upward from the central opening. It has a tray side wall and a tray bottom wall connected to the upper end of the tray side wall.
[0023]
In the vertical food packaging container configured as described above, the second object described above is achieved. For this purpose, the outer lid is removed from the outer container, and the partition member is taken out of the outer container. Next, the partition member is placed upside down on a table or the like. As a result, the tray portion of the partition member can be used as a tray or a cup.
[0024]
In particular, when the food contained in the outer container has a material that easily adheres to the small container, such as oil and salt, this vertical food container is advantageous. During transportation of the food packaging container, the oil and salt of the food contact and adhere to the central opening side of the partition member. In contrast, food oil and salt do not adhere to the tray bottom wall side of the partition member. When the partition member is taken out from the outer container and placed upside down on a table or the like, the central opening side of the partition member to which oil and salt are attached is upward, and the partition to which oil and salt are not attached The tray bottom wall side of the member faces downward. As a result, the upper surface of the table is not soiled by food oil and salt.
[0025]
In the present invention, preferably, at least two recesses straddling the tray side wall and the tray bottom wall are provided.
[0026]
In the vertically placed food packaging container configured as described above, after removing the outer lid from the outer container, a finger can be put into the recess, the partition member can be grasped, and the partition member can be taken out of the outer container. In this case, the volume of the tray portion can be increased in the lateral direction by increasing the outer diameter of the tray bottom wall. Two recesses are preferably provided in the diameter direction.
[0027]

Furthermore, in the outer container 4, a partition member 20 for partitioning the container internal space 18 up and down is disposed above the snack confectionery S with a space therebetween. A source bag 22 is placed on the partition member 20. The sauce bag 22 contains a dip sauce to be attached to the snack confectionery S and has a flat shape. The snack confectionery S, the partition member 20 and the sauce bag 22 are arranged in a sealed container internal space 18.
[0031]
Next, the partition member 20 will be described in detail with reference to FIGS. 1 and 2. FIG. 2 is a plan view of the partition member.
[0032]
The partition member 20 includes a donut disk-shaped partition plate 26 including a central opening 24, and an annular extension 30 that extends upward from the peripheral edge 28 of the partition plate 26 along the inner surface 16 of the side wall 8. The partition plate 26 has an outer diameter equal to the inner diameter of the vertical intermediate portion 32 of the inner surface 16 of the side wall 8. Thus, the partition plate 26 is in contact with and held by the vertical intermediate portion 32. The length of the extended portion 30 in the vertical direction is preferably a length that prevents the partition member 20 from being inclined during transportation of the food packaging container 1. This length is preferably 2 mm to 10 mm, but may be larger.
[0033]
The partition member 20 further includes a tray portion 34 that is configured to include the central opening 24 and that is opposite in the vertical direction. The tray portion 34 has an annular tray side wall 36 extending upward from the central opening 24, and a tray bottom wall 40 connected to the upper end 38 of the tray side wall. The tray bottom wall 40 has an upward bottom surface 42 on which the source bag 22 is placed. When the partition member 20 is taken out of the outer container 4 and placed upside down, the bottom surface 42 faces downward and the central opening 24 faces upward, so that the partition member 20 can be used as a tray or a cup. The cross section of the tray side wall 36 is tapered so as to gradually decrease from the central opening 24 to the tray bottom wall 40. The volume of the tray portion 34 is determined by the outer diameter of the central opening 24, the vertical length of the tray side wall 36, and the diameter of the tray bottom wall 40. The vertical length of the tray side wall 36 is, for example, a dimension such that the source bag 22 disposed between the outer lid 6 and the tray bottom wall 40 does not move in the vertical direction during transportation of the food packaging container 1. . The diameter of the tray bottom wall 40 is, for example, 20 to 30 mm smaller than the inner diameter of the intermediate portion in the vertical direction of the side wall of the outer container 4.
