Description

The present invention relates to a bowl-type food packaging container including a main body, a middle plate, and a lid.

In recent years, various types of noodles such as chilled Chinese noodles such as chilled Chinese noodles and ramen, simmered soba noodles, and various rice bowls such as Chinese rice bowls are sold at convenience stores and supermarkets, etc., which can be eaten as-is without the need for cooking after purchase. There is. These foods are housed in a bowl type food packaging container as described in Patent Document 1 below. In these bowl-shaped containers, a round container shape is particularly preferred.

In a bowl-type food packaging container, for example, an inner plate is used in addition to a main body and a lid to separately store noodles and ingredients. The main body, the inner plate, and the lid are each formed of a synthetic resin sheet. Ingredients such as noodles are stored in the main body, and ingredients to be placed on noodles are stored in the middle plate. When the inner plate is provided with a partition wall section for partitioning the storage space, different types of ingredients are stored in the plurality of storage chambers partitioned by the partition wall section. Then, in the packaged state containing the food, the band-shaped label on which various information such as the name of the food is printed is wound up and down from the top surface portion of the lid to the bottom surface portion of the main body.

For example, chilled noodles such as chilled Chinese noodles will be taken as an example to describe the work steps until product completion. First, the noodles are stored in the main body, and then the inner plate is placed on the main body. Place various ingredients such as eggs, cucumbers and tomatoes on the inner plate. Then, after covering with the lid, the band-shaped label is wrapped to complete the product.

The purchaser sees the information contained in the strip label and at the same time sees the ingredients contained in the inner plate, so that the orientation of each ingredient contained in the inner plate and the orientation of the strip label are neatly aligned. Required to be present. Since the bowl-shaped container has a round shape, when placing the inner plate on the main body, it is not possible to position the inner plate with respect to the main body in the circumferential direction and to further position the lid with respect to the inner plate in the circumferential direction. Although not easy, in the past, it was necessary to perform the positioning work manually one by one, which required a great amount of work.

On the other hand, in the container described in Patent Document 2 below, a configuration is proposed in which a notch is provided on the outer edge of the inner plate, and the notch is locked to the main body to position the inner plate. .. However, when the notch is provided in the inner plate, there is a problem that a crack is likely to occur in the sheet forming the inner plate starting from the notch.

The present invention provides a bowl-type food packaging container capable of easily positioning the position of the inner plate in the circumferential direction while maintaining the round container shape required for the bowl-type food packaging container. Is an issue.

The bowl-shaped food packaging container according to the present invention is made of a synthetic resin sheet, and includes a main body having a substantially circular outer edge in plan view, a middle plate, and a lid having a substantially circular outer edge in plan view, What is claimed is: 1.A bowl-type food packaging container, in which a belt-shaped label is vertically wound and used in a united state in which a main body, an inner plate, and a lid are united, and the main body includes a main body bottom portion, a main body side wall portion, and a main body. The main body flange portion includes a main body horizontal plane portion that extends substantially horizontally from the upper end of the main body side wall portion toward the outside, and is located outside the main body horizontal plane portion and protrudes upward over substantially the entire circumference. The protrusion includes a protrusion, a fitting portion outside the main body that is substantially circular in plan view and is located outside the protrusion, and a main body grip portion that is formed at a predetermined position on the outer edge of the main body flange portion. An inner side surface portion that rises upward from the outer edge of the outer side surface portion, an outer side surface portion located outside the inner side surface portion, and a top surface portion that connects the upper end of the inner side surface portion and the upper end of the outer side surface portion. The side surface on the inner side of the ridge has a substantially polygonal shape in a plan view, and the middle plate includes a middle plate bottom part, a middle plate side wall part, a partition wall part and a middle plate flange part, and the middle plate flange part is A base plate portion extending outward from the outer edge of the middle plate side wall portion, a rising wall portion rising upward from the outer edge of the base plate portion, and a middle plate horizontal plane portion extending substantially horizontally from the upper end of the rising wall portion toward the outside. The rising wall portion has a substantially polygonal shape in plan view corresponding to the inner side surface portion of the protrusion of the main body, and the lid includes a top surface portion, a lid side wall portion, and a lid flange portion, and a peripheral portion of the top surface portion A pair of guard protrusions are provided so as to face each other and project upward, a band-shaped label is wound between both guard protrusions in a united state, and the lid flange portion is outside the main body fitting unit in a united state. A lid outer fitting portion that is substantially circular in a plan view and that fits to the lid, and a lid grip portion that is formed at a predetermined location on the outer edge of the lid flange portion. The middle plate is positioned in the circumferential direction by the engagement of the rising wall portions of the plate.

In the bowl-shaped food packaging container having the above structure, the inner plate is placed in a state where the main ingredients such as noodles are contained in the main body. When the inner tray is placed on the main body, the base surface portion of the inner tray is placed on the horizontal surface portion of the main body. The horizontal surface of the middle plate may or may not contact the top surface of the ridge of the main body. When the inner plate is placed on the main body, the position of the inner plate in the circumferential direction can be aligned with the main body by using the main body picking portion of the main body and the partition wall portion of the main plate as a guide. Then, when the inner plate is placed on the main body, the rising wall portion of the inner plate engages with the inner side surface of the ridge of the main body to determine the position of the inner plate in the circumferential direction with respect to the main body. The inner surface of the inner side surface of the protrusion of the main body and the outer surface of the rising wall portion of the inner plate may or may not contact each other. The clearance may be such that the rising wall portion of the inner plate does not rotate in the circumferential direction with respect to the inner side surface portion. Further, since the side surface of the inner side of the protrusion of the main body and the rising wall portion of the inner plate are substantially polygonal in plan view, the position of the inner plate in the circumferential direction can be easily positioned with respect to the main body. For example, ingredients are stored in the middle plate. The inner plate is provided with a partition wall portion, and the partition wall portion divides the storage space of the inner plate into a plurality of storage chambers. Different ingredients can be stored in the plurality of storage chambers. When the lid is put on, the lid picking portion can be used as a guide to put the lid on the main body and the inner plate in a predetermined direction. After that, the band-shaped label is wound, but since the inner plate is positioned at a predetermined position in the circumferential direction with respect to the main body and the lid, the band-shaped label and the inner plate are in a neat state. That is, the food such as the ingredients contained in the inner plate and the strip-shaped label are neatly arranged, and the product looks good.

In particular, in a predetermined portion of the entire circumference of the upper part of the main body side wall part, a part of the main body horizontal surface part is cut out, and the concave part is provided outward from the upper part of the main body side wall part toward the ridge for food removal. It is preferable that the mouth part is formed. When the drinking spout is formed in this way, foods such as noodles can be easily eaten from the drinking spout. In addition, since the mouthpiece has a protruding shape that bulges outward, it is possible to easily align the circumferential position of the body with the protruding shape of the mouthpiece when the bodies are stacked and packed at the time of shipping. .. As a result, the positions of the main body knobs are aligned, and the main body knobs are prevented from being bent during packaging.

Further, the inner side surface of the ridge of the main body has a substantially polygonal shape in plan view in which at least one side is longer than the other sides, and the rising wall portion of the inner plate corresponds to the inner side surface of the ridge of the main body. Then, if at least one side is substantially polygonal in plan view longer than the other sides, the inner plate can be easily aligned with the main body in a predetermined direction, and the assembling workability is improved.

As described above, the position of the inner plate in the circumferential direction can be easily positioned, and the food such as ingredients contained in the inner plate and the band-shaped label are in a neat state, which is excellent in aesthetics. The product is obtained. In addition, the round container shape required for a bowl-type food packaging container can be maintained.
