TECHNICAL FIELD OF THE INVENTION
The present invention relates to a food packaging container, and more particularly, to a vertical food packaging container.
[0002]
[Prior art]
BACKGROUND ART Vertically placed food packaging containers containing foods such as confectionery, noodles, yogurt, pudding, soda-ten, natto, and instant miso soup are known and used by many manufacturers. These food packaging containers are hermetically sealed, and the food packaging containers often contain jams such as soups, sauces, butters, creams, ketchups, mayonnaise, fruit sauces, flavorings such as dressings, spices, seasonings, and solid ingredients. Materials are attached.
[0003]
There are also known food packaging containers having a partition member for separating food and a flavoring agent or solid ingredient, in addition to simply attaching the flavor or solid ingredient to the food packaging container. (See Patent Documents 1 to 3).
[0004]
FIG. 3 is a longitudinal sectional view of one exemplary food packaging container (see Patent Document 1). The food packaging container 60 includes a cup 62, a partition 68 having a storage dish 64 and an opening 66, and a lid 70. The cup 62 has a side wall 72 and a flange 74 provided on an upper edge of the side wall 72. The cross section of the cup 62 continuously decreases from the upper side to the lower side. A partition member 68 is bonded on the flange 74, and a lid 70 is further bonded on the upper surface of the partition member 68. The storage plate 64 is arranged so as to hang from the partitioning tool 68.
[0005]
In the food packaging container having such a configuration, the confectionery is stored in the cup 62 partitioned by the partitioning tool 68, and the chocolate liquid for painting and eating the confectionery is stored in the storage plate 64 of the partitioning tool 68. .
[0006]
FIG. 4 is a longitudinal sectional view of another example food packaging container (see Patent Document 3). The food packaging container 80 has a main body container 82 and a middle plate container 84. The main body container 82 has a side wall 88 provided with a stepped portion 86 or a concave portion (not shown). The flange portion 90 of the inner plate container 84 engages with the stepped portion 86 or the concave portion of the main container 82 so that the inner plate container 84 is held on the side wall 88.

[0009]
[Problems to be solved by the invention]
When preparing a food packaging container having a partition, 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, compared with the case where the food packaging container without the partitioning tool 68 is manufactured, the bonding step is one. The number of processes increases. That is, the production of a food packaging container without the partitioning tool 68 may include the step of bonding the cup 62 and the lid 70, whereas the production of the food packaging container 60 having the partitioning tool 68 is And a step of bonding the partitioning tool 68 and the lid 70 to each other. Adding one bonding step is a large-scale operation, and a large 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 container 82, the stepped portion or the concave portion is formed on the side wall of the main container. A processing step for forming a stepped portion or a concave portion in the mold of the main body container is added as compared with the case where a food packaging container having no food packaging container is manufactured, thereby increasing the manufacturing cost. Furthermore, if a partition can be added by diverting a food packaging container having no stepped portion or concave portion on the side wall, the cost of manufacturing the mold of the main body container can be further reduced.
[0012]
As another viewpoint, it is convenient if the partition can be used as a tray or a cup for holding a flavoring agent, as in the above-described conventional food packaging container (see Patent Document 1).
[0013]
Therefore, a first object of the present invention is to provide a vertically placed food packaging container to which a partition can be added at low cost.
[0014]
Further, a second object of the present invention is to provide a vertical food packaging container in which a partition can be added at 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 first object, a vertical-type food packaging container according to the present invention includes a vertical-type outer container having an annular side wall and an upward opening formed by the side wall; An outer lid, and a partition member for vertically partitioning the container internal space formed by the outer lid and the outer container, and the side wall has a substantially circular cross section and the cross section is formed from above to below. The partition member has an outer diameter equal to the inner diameter of the vertical middle part of the inner surface and has a substantially circular partition plate held by the vertical middle part. It is characterized by.
[0016]
In the vertical-type food packaging container configured as described above, the partition plate is put into the outer container through the opening of the outer container, and when the partition plate is further lowered, the outer diameter of the partition plate is equal to the inner diameter of the side wall in the vertical direction. At the middle part, the partition plate catches on the inner surface of the side wall. Thereby, the partition plate is held and positioned at the intermediate portion of the side wall. As a result, the container internal space is vertically partitioned.
[0017]
In this vertical food packaging container, it is not necessary to add an adhesive step to add a partition member, and it is not necessary to add a processing step for providing a stepped portion or a concave portion in the outer container mold. As a result, partitions can be added at low cost. In addition, when using a vertical type outer container having an inner surface whose cross section continuously decreases from top to bottom, which is actually used by many manufacturers, without manufacturing a mold for the outer container. , Partitions can be added. Thereby, the manufacturing cost can be further reduced.
[0018]
In this vertical-type food packaging container, by changing the outer diameter of the partition plate, the position of the vertical intermediate portion of the side wall on which the partition member is held may be changed. Also, the inner surface, whose cross section decreases continuously from above to below, does not need to be present 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 the present invention, preferably, the partition member has an annular extension extending from the peripheral edge of the partition plate along the inner surface of the side wall.
[0020]
In the vertical-type food packaging container configured as described above, since the extended portion extends along the side wall, the partition member is firmly held at the middle portion in the vertical direction. Thereby, for example, during transportation of the food packaging container, it is possible to prevent the partition member from rotating in the outer container. In this case, the length of the extension in the vertical direction is preferably 2 mm to 10 mm.
[0021]
The extension 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 provided in the central opening in a vertically opposite 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]
The above-described second object is achieved in the vertically placed food packaging container configured as described above. 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, for example, 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. On the other hand, food oil and salt do not adhere to the tray bottom wall side of the partition member. When the partition member is taken out of the outer container and placed upside down on a table or the like, the center opening side of the partition member to which oil and salt are attached faces upward, and the partition to which oil and salt are not attached. The member bottom wall side faces downward. As a result, the upper surface of the table is not stained with food oil and salt.
[0025]
In the present invention, preferably, at least two concave portions are provided to extend over the tray side wall and the tray bottom wall.
[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 concave portion, the partition member can be grasped, and the partition member can be taken out of the outer container. In this case, by increasing the outer diameter of the tray bottom wall, the volume of the tray portion can be increased in the lateral direction. It is preferable to provide two concave portions in the diameter direction.
[0027]
