Description

  The present invention relates to a packaging container that is placed so as to place a container such as food.

  Conventionally, a container body of a packaging container for storing food such as lunch boxes and side dishes sold at supermarkets and convenience stores has been provided with a partition and a bank so that the food does not deviate from its position. However, the way the food is arranged varies depending on the type of food, and the more the food that looks good or bad, the more the food is affected. The production is not only misaligned, it is less likely to lose its shape, and quality such as freshness is transmitted to consumers. It was.

  For example, Patent Literature 1 discloses a rod-shaped rib that protrudes in the longitudinal direction and upward from the center of the food placing surface surrounded by the bank. The height of the rib is lower than the height of the bank (refer to the AA sectional view). On the other hand, the detailed shape and size of the rib are not disclosed. Further, Patent Document 2 discloses a spot-like convex portion that prevents unevenness of sushi or the like provided on a food placement surface and a rising rib that surrounds the placement surface and prevents outflow of juice or the like. Yes.

Design Registration No. 1479733 Japanese Patent No. 4951635

  However, in Patent Document 1, when the packaging container is tilted, the food on the upper side of the placement surface gets over the rib and pushes the food on the lower side, so that the food on the lower side may get over the bank. Moreover, in patent document 2, since the space | interval of adjacent convex parts is too wide, since it is hard to expect the position shift effect of foodstuffs, it is difficult for an operator to know the food mounting place, and therefore the work efficiency is reduced. There is a risk of inviting.

  In particular, in the case of high-grade food such as sushi, it is expected to prevent misalignment due to the inclination of the container itself and loss of shape due to collision between foods because the food is arranged or regularly arranged on the mounting surface. . For this reason, a rib-like stopper or bank is required on the mounting surface to prevent food from being displaced and food from colliding with each other even when the packaging container is tilted, so that the food can maintain its desired state of placement. In some ways, the creators have arrived.

  Accordingly, an object of the present invention is to provide a packaging container capable of maintaining a desired position and state without impairing the appearance and arrangement work efficiency of stored items such as food.

  That is, the packaging container according to the present invention prevents the misalignment of the contents by projecting upward from the center of the placing surface portion, the embedding portion surrounding the placing surface portion, and the embedding portion surrounding the placing surface portion. It is characterized by comprising a container retaining part, wherein the height of the container retaining part is higher than the height of the bank part.

  Further, the packaging container is positioned between the bottom portion having the placement surface portion and the bank portion, a flange portion extending outward from a peripheral edge of the bottom portion, and the bottom portion and the flange portion. And it is desirable to provide the leg part which protrudes below.

  In addition, it is desirable that the above-described storage object holding portion has a planar storage object contact portion, and the angle of the storage object contact portion with respect to the placement surface portion is 40 to 65 °.

  Moreover, it is desirable that the height in the vertical direction from the placement surface part to the apex of the above-mentioned storage object holding part is 1.5 to 2.5 mm.

  Moreover, it is desirable that the packaging container further includes a lid.

  According to the packaging container of the present invention, it can be expected to maintain a desired position and state without impairing the appearance and arrangement efficiency of the contents such as food. More specifically, since the container retaining portion is non-slip, it can be expected that the bias of the container is prevented even when the packaging container is tilted. Furthermore, since the bank portion is lower than the containment fastening portion, the containment can be easily seen to the bottom, and it is difficult to affect the placing work.

The container contact portion 13b may be a concave or convex curved surface. The height H may change discontinuously.

  The container main body C1 and the lid C2 in the present embodiment may be formed by thermoforming a synthetic resin sheet by sheet molding such as vacuum molding, hot plate pressure molding, vacuum pressure molding, double-side vacuum molding, or the like. Good. As the synthetic resin sheet, for example, a polyester-based resin such as polyethylene terephthalate or an olefin-based resin such as polypropylene, a single-layer or multilayer sheet may be used, and it may be colored or colorless and transparent, or opaque. As the resin, for example, if a foamed resin is used, it is preferable because it is lightweight and has heat insulating properties. Furthermore, the front surface or the back surface of the sheet may be covered with a synthetic resin film, and when the surface is covered, printing may be performed. The thickness of the synthetic resin sheet is not particularly limited, but may be 0.2 to 1.0 mm, preferably 0.3 to 0.8 mm, and more preferably 0.4 to 0.6 mm.
