Utility Model Registration No. 3076195

An object of the present invention is to provide a packaging container that can suppress the sinking of food.

A packaging container according to the present invention comprises a container body in which a bottom plate having a first face and a second face vertically opposite to the first face is surrounded by an outer frame, and a transparent lid covering the container body. A packaging container comprising a It is possible to cover the container body of the first mode facing upward and the container body of the second mode with the second surface of the bottom plate facing upward from the upper side, and the lid body is closed when the lid is closed. It has a top portion located above the outer frame. Either the first surface or the second surface of the bottom plate may be the front surface. For example, if the first surface is the front surface, the second surface is the back surface.

According to this configuration, the bottom plate is positioned in the center of the outer frame in the vertical direction, and the container body is arranged in the first mode in which the first surface of the bottom plate faces upward, and in the second mode in which the second surface of the bottom plate faces upward. It can be used in both modes. That is, the container main body is a so-called reversible one that can be used upside down. In addition, since the bottom plate is positioned in the center of the outer frame in the vertical direction, when food such as sushi is placed on the bottom plate, the upper portion of the food will protrude above the upper end surface of the outer frame. The food can be placed on the bottom plate immediately, and the food does not sink easily, and a good appearance can be obtained. Since the top surface of the lid covering the container main body is positioned above the outer frame, the space for accommodating the entire container is secured, and the food served on the bottom plate is exposed to the outside through the lid. can be easily seen from

In particular, it is preferable that the first surface and the second surface of the bottom plate have patterns or colors different from each other. By inverting one container body upside down, two types of containers with different appearances and tastes can be obtained. For example, when putting in sushi, the first and second sides of the bottom plate can be used depending on the type and quality of the toppings. Since it is no longer necessary to store two types of container bodies with different appearances, it is possible to reduce the amount of container bodies to be stored in the backyard or the like of the store, thereby reducing the storage area.

As described above, according to the packaging container of the present invention, it is possible to suppress the sinking of food, and the container body can be turned upside down for use. If the first surface and the second surface of the bottom plate have different patterns or colors, by turning the container body upside down, two different types of containers can be obtained. Therefore, it is no longer necessary to store two types of container bodies with different tastes, and the amount of container bodies to be stored in the backyard or the like in the store can be reduced, and the storage area can be reduced.

The bottom plate 10 is a single thin flat plate, and both the first surface 10a and the second surface 10b may be flat surfaces without unevenness, or may have unevenness. For example, at least one of the first surface 10a and the second surface 10b may be provided with protrusions or ridges for suppressing positional displacement of the sushi. Either of the first surface 10a and the second surface 10b may be the surface. The bottom plate 10 is preferably made of thermoplastic resin, particularly foamed resin, but may be made of paper. The bottom plate 10 is preferably a synthetic resin sheet.

Let one surface be the 1st surface 10a among both surfaces of the baseplate 10, and let the other surface be the 2nd surface 10b. The first surface 10a may be the front surface and the second surface 10b may be the back surface, or conversely, the first surface 10a may be the back surface and the second surface 10b may be the front surface. The first surface 10a and the second surface 10b of the bottom plate 10 preferably have different appearances. Specifically, it is preferable that the first surface 10a and the second surface 10b have different colors or patterns. The first surface 10a and the second surface 10b may be made of different materials to have different appearances. In this embodiment, the colors of the first surface 10a and the second surface 10b are different from each other. For example, the first surface 10a may be black and the second surface 10b may be red, the first surface 10a may be gold and the second surface 10b may be red, or the first surface 10a may be gold and the second surface may be red. 10b can also have a grain pattern.

When the bottom plate 10 has different colors and patterns (patterns) on both sides in this manner, two different tastes of the container body 1 can be obtained by turning the container body 1 upside down. 1 and 2 show a state in which the first surface 10a of the bottom plate 10 faces upward, and this state is defined as a first mode. 3 and 4 show a state in which the second surface 10b of the bottom plate 10 faces upward, and this state is referred to as a second mode. When the container body 1 in the first mode (first posture) is turned upside down, it becomes the second mode (second posture). As shown in FIG. 2, the container body 1 of the first mode can be covered with the lid 2, and as shown in FIG. can be covered from

<Outer frame 11>
The outer frame 11 constitutes a side wall of the container body 1 . The outer frame 11 is formed by bending a thin sheet made of foamed resin into a square tube shape. The outer frame 11 has, for example, a rectangular shape in plan view. The outer frame 11 is preferably made of thermoplastic resin, particularly foamed resin, but may be made of paper. The outer frame 11 is preferably a synthetic resin sheet.

As shown in FIG. 5, a groove 12 is formed in the center of the inner surface of the outer frame 11 in the vertical direction. The groove 12 is preferably formed along the entire circumference of the inner surface of the outer frame 11 . The depth of groove 12 may be half or more of the thickness of outer frame 11 . A bottom plate 10 is fixed in this groove 12 . A peripheral portion of the bottom plate 10 is fitted in the groove 12 . It is preferable that the peripheral portion of the bottom plate 10 is fitted in the groove 12 over the entire circumference. The bottom plate 10 is preferably bonded to the outer frame 11 by thermal fusion or glue. It is also preferable to use heat fusion and glue adhesion together. For example, the corners may be heat-sealed, and the other sides may be glued together. The bottom plate 10 is positioned at the center of the inner surface of the outer frame 11 in the vertical direction, and the container body 1 has a vertically symmetrical shape. The housing space for the container body 1 is formed by the outer frame 11 and the bottom plate 10, and the housing space for the container body 1 remains substantially the same even when the container body 1 is turned upside down. That is, the container body 1 of the first mode and the container body 1 of the second mode have the same accommodation space. The accommodation space of the container body 1 of the first mode is the space between the first surface 10a of the bottom plate 10 and the first end face 11a of the outer frame 11, and the accommodation space of the container body 1 of the second mode is the space between the bottom plate 10 is a space from the second surface 10b of the outer frame 11 to the second end surface 11b of the outer frame 11. The container body 1 is a reversible container that can be turned upside down and used.

As shown in FIG. 6, the container bodies 1 can be vertically stacked. Since the container body 1 has a vertically symmetrical shape, it can be stacked without worrying about the vertical direction.

The synthetic resin sheet used for the outer frame 11 and the bottom plate 10 includes a foam layer that constitutes the main part of the sheet, and first and second non-foam layers that are thinner than the foam layer and cover both sides of the foam layer. and a layer. Materials for the foam layer include, for example, styrene resins such as polystyrene, polyester resins such as polyethylene terephthalate, and olefin resins such as polypropylene. The material of the non-foamed layer may be the same as that of the foamed layer, and examples thereof include styrene resins such as polystyrene, polyester resins such as polyethylene terephthalate, and olefin resins such as polypropylene. The sheet used for the outer frame 11 and the bottom plate 10 is, for example, a foam sheet laminated with synthetic resin films on both sides thereof. The foam sheet constitutes the foam layer and the film constitutes the non-foam layer. The film may be a styrene resin film, a polyester resin film, an olefin resin film, or the like, and may be a film obtained by stretching them. A specific example of the sheet is a polystyrene foam sheet laminated with polystyrene films on both sides thereof. By laminating films with different colors and patterns on both sides of the foam sheet, the first surface 10a and the second surface 10b of the bottom plate 10 can be easily given different colors and patterns.

The opening angle of the lid side surface portion 21 to the outside is preferably less than 45 degrees, and the lid side surface portion 21 preferably extends downward at a steep angle close to a right angle with respect to the top surface portion 20 . In other words, it is preferable that the lid side surface portion 21 rises upward with respect to the lid flange portion 22 at an angle close to a right angle. The lid side portion 21 is provided with an anti-blocking projection 23 in order to prevent a so-called blocking phenomenon in which the lids 2 are tightly fitted to each other and cannot be removed when a large number of the lids 2 are stacked. good. The anti-blocking projections 23 are arranged with their positions shifted for each cover 2 . Various reinforcing ribs may be provided on the lid side surface portion 21 . The vertical dimension H (height) of the lid side portion 21 is preferably equal to or greater than the vertical dimension D between the bottom plate 10 and the upper end surface of the outer frame 11 .

The lid flange portion 22 includes an extending portion 22a extending substantially horizontally outward from the lower end of the lid side portion 21, and a skirt portion 22b extending downward from the outer edge of the extending portion 22a. The inner surface of the skirt portion 22b is preferably provided with a fitting projection 22c projecting inward, but the fitting projection 22c may be omitted. The fitting protrusion 22c may be, for example, a long protrusion along the horizontal direction. The fitting protrusions 22c may be provided at a plurality of locations at intervals in the horizontal direction. A fringe portion 22d extending substantially horizontally toward the outside is preferably provided at the lower end of the skirt portion 22b. On the outer edge side of the edging portion 22d, a large number of very fine irregularities may be formed to reinforce the rim portion 22d and prevent a finger from being cut even if it hits the rim portion 22d. When viewed from the front, the unevenness has a wavy shape, with a large number of peaks and troughs formed short in the width direction on each side, and a direction connecting the corners and the center at the corners (radiating direction). direction). Further, the unevenness is formed by, for example, flat knurling or twilled knurling, and is preferably formed by twilled knurling in order to prevent slippage. The lid flange portion 22 may be provided with a knob (not shown) for facilitating the lid opening operation.

The lid body 2 is formed from a synthetic resin sheet by various thermoforming (sheet forming) methods such as vacuum forming and pressure forming. For the cover 2, a synthetic resin sheet such as polyethylene terephthalate, polystyrene, or polyolefin such as polypropylene or polyethylene can be used. A sheet obtained by filling these synthetic resins with an inorganic substance may be used, or a stretched sheet obtained by stretching the above-described sheet may be used. Among them, stretched sheets obtained by uniaxially stretching or biaxially stretching transparent polyethylene terephthalate, polystyrene, polypropylene or the like are particularly preferable.

FIG. 7 shows the closed state. The bottom plate 10 may have the first surface 10a facing upward or the second surface 10b facing upward. As an example, the first aspect in which the first surface 10a faces upward is illustrated. . The food 100 is placed on the upward facing side of the bottom plate 10, that is, the first side 10a in this example. In the lid closed state, the extending portion 22a of the lid flange portion 22 abuts against the upper end surface of the outer frame 11 or confronts it with a slight gap therebetween. The upper end face of the outer frame 11 is the first end face 11a or the second end face 11b, but in this example it is the first end face 11a. It is preferable that the lower end of the lid side surface portion 21, that is, the inner edge of the extending portion 22a substantially coincides with the inner edge of the upper end surface of the outer frame 11 in plan view. The skirt portion 22b is fitted to the outside of the outer frame 11, that is, is fitted outside. The fitting protrusion 22c abuts on the outer surface of the outer frame 11 . The lid-closed state is maintained by abutment of the fitting convex portion 22c against the outer surface of the outer frame 11 . The top surface portion 20 is positioned above the upper end surface of the outer frame 11 .

The accommodated food 100 , that is, the food 100 placed on the bottom plate 10 protrudes upward from the upper end surface of the outer frame 11 . The upper portion of food 100 protrudes above the upper end surface of outer frame 11 . It is preferable that more than the upper half of the food product 100 protrude above the upper end surface of the outer frame 11 . Since the lid side portion 21 is provided, the storage space for the container can be increased. The food 100 can be visually recognized from the outside through the lid body 2 , and in particular, the food 100 can be visually recognized from the top surface portion 20 and also from the side surface portion 21 of the lid.

As shown in FIG. 8, the closed containers can be stacked one above the other. The lid 2 of the lower container is inserted into the lower portion of the outer frame 11 of the upper container. The upper container is placed on the top surface portion 20 of the lid 2 of the lower container. The bottom plate 10 of the upper container contacts the top surface 20 of the lower container. Since the lid body 2 of the lower container is inserted inside the lower part of the outer frame 11 of the upper container, the height of the stacked container can be compressed, and the lateral displacement of the containers is suppressed. .

In the container constructed as described above, the container main body 1 can be used upside down. Moreover, as shown in FIG. 7 , the upper portion of the food 100 placed on the bottom plate 10 protrudes above the upper end surface of the outer frame 11 . Therefore, the food 100 is less likely to sink, and a good appearance can be obtained. Since the top surface portion 20 of the lid body 2 is positioned above the upper end surface of the outer frame 11, a space for accommodating the entire container is secured, and the food 100 served on the bottom plate 10 is placed on the top surface portion of the lid body 2. It can be easily visually recognized from the outside through 20 and the lid side portion 21 .

Also, if the first surface 10a and the second surface 10b of the bottom plate 10 have different appearances, by turning one container body 1 upside down, two different types of containers can be obtained. For example, the first surface 10a and the second surface 10b of the bottom plate 10 can be selectively used depending on the type and quality of sushi toppings. Alternatively, the first surface 10a and the second surface 10b of the bottom plate 10 can be used separately for each type of food 100, such as sushi and roast beef. Various uses are possible, such as using the surface 10b for roast beef. Since one container body 1 can be used for two types of usage, it is not necessary to store two types of container bodies 1 having different colors and patterns on the bottom plate 10, and the container body 1 is stored in a backyard or the like in a store. Quantity and storage space can be reduced to 1/2.
