Description

  The present invention relates to a packaging container particularly suitable for steamy foods such as takoyaki.

  As a container for protecting stored items from moisture, it is known to form a container with a hygroscopic material or to form a drain hole on the bottom surface or lid surface of the container.

However, in the container as described above, the cost is high, or the contact surface of the stored item is deteriorated by wetting due to water absorption, and there is a possibility that moisture is not necessarily discharged out of the container and collected in the container. There was a risk of falling water and soiling the surrounding area.
The present invention is intended to provide a packaging container having a unique configuration from a viewpoint different from that of conventional containers for the purpose of protecting stored items from steam, moisture or gas generated therefrom. It is.

In order to solve the above-mentioned problem, the present invention is a container formed with flanges that can face each other on both peripheral portions of the container main body and the lid, and the top surface of the lid has its center at the top, It is formed as a downward inclined surface from the top toward the opposite side edges, and a convex portion that is intermittent in the circumferential direction is formed on the collar portion of the container body, and the lid so as to face the convex portion of the container body in the closed state It is characterized by forming a convex part in the collar part of the container, and maintaining a gap between both collar parts outside the convex part in a state where the convex parts are joined to each other, thereby making a packaging container. To do.
It is preferable that the convex portion is formed at a portion closer to the inside of the collar surface. Moreover, it is preferable to form the recessed part which has the inclined surface which expands toward the inner side of a container in the collar surface between the said convex parts so that both the collar parts of a container main body and a lid may be opposed.
It is preferable to form an uneven rib on the top surface of the lid along the downward direction of the downward inclined surface from the top.

Hereinafter, an example of implementation according to the present invention will be described with reference to the drawings.
The container according to the present invention comprises a container main body 1 and a lid 11, and the material is not limited. Preferably, a transparent plastic sheet such as PET is formed by thermoforming such as compressed air vacuum forming and integrally formed on one side. It can be opened and closed through the hinge 10.

  The container body 1 is formed so as to have a container shape as appropriate by the bottom surface 2 and the peripheral side surface 3, and the upper peripheral edge of the peripheral side surface 3 is folded outward to form a substantially horizontal flange 4. Protruding part 5 having an appropriate length in the circumferential direction and slightly projecting upward is integrally formed so as to be intermittently arranged over the entire circumference while appropriately spacing in the circumferential direction of the part 4; Between each convex part, it is set as the flat surface.

  The convex portion 5 may be formed so as to make the ridge surface uneven over the entire width of the ridge, but it is preferable that the convex portion is formed on the inner side of the ridge surface as a width slightly more than half the ridge width from the inside of the container. , This gives strength to the buttock and allows the convex part to be stably molded. It can be formed around the edge surface to make a safe container. A concave portion 6 having an inclined surface 6a which is inclined downward toward the inner side of the container and expands is formed at an appropriate location between the convex portions.

  The lid 11 is formed by the top surface 12 and the peripheral side surface 13 so as to have an appropriate lid shape that can be closed on the container body, and the top surface 12 has a top (center) portion as a top portion 12a. , 3 as a slight downward inclined surface from the top to the opposite side edges, preferably toward the short side edges of the lid, as shown in FIG. A shaped collar 14 is formed.

  While facing the convex part 5 of the said container main body 1 in the circumferential direction of this collar part 14 suitably, it is below a collar surface so that it can join with this convex part 5 as shown in FIG. A protruding portion 15 is integrally formed so that a gap is maintained between the flange surfaces of both flange portions 4 and 14 in the closed state. The protrusions of both convex portions 5 and 15 are set to such a degree that a gap is not formed more than necessary so that a slight gap is formed between the both flange portions, and foreign matter does not easily enter the container from the outside. Is preferred. In the closed state, it is preferable to set the gap between the outer edges of the buttock to be, for example, about 1 to 5 mm.

Between the convex portions 15, a concave portion 16 having an inclined surface 16 a that is opposed to the concave portion 6 and has an inclined surface 16 a that is inclined upward toward the inner side of the container is formed at a portion facing the concave portion 6 of the container body. In the closed state, as shown in FIG. 3, a gap that expands from the outer edge of the bag toward the inside of the container can be formed between the concave portions 6 and 16.
In addition, although not shown in figure, the said convex parts 5 and 15 can form the uneven | corrugated or reverse taper-shaped engaging part so that a closed state can be maintained.

The container body 1 and the lid 11 can be appropriately formed with ribs at appropriate positions.
The top surface 12 of the lid 11 is attached, for example, by forming a plurality of concave and convex ribs 12b as shown in FIG. 4 along the descending inclined surfaces toward the both lateral edges of the short width of the lid through the top portion 12a. It is preferable because water droplets and the like are easily transmitted toward both edges.
The bottom surface 2 of the container body 1 is provided with, for example, concave and convex ribs 2a provided to be the bottom main body and concave groove ribs 2b provided at appropriate intervals so that the stored items do not stick to the bottom surface. It is preferable to form them in parallel. It is preferable that at least the rib 2a is continuously formed up to the upper part of the peripheral side surface.

Using the container with the above configuration is suitable for storing items such as takoyaki and other foods that are easily exposed to steam, moisture, gas, etc., and without damaging the items stored during take-away or other transportation or store displays. Can be kept in good condition.
The center of the top surface of the lid is the top, and the top surface is inclined downward toward both side edges, so that vapor generated in the container tends to flow from the top surface of the lid toward both side edges. If there is a rib or the like on the top surface along the inclined direction, it becomes easier to flow and the stored items are less likely to be damaged. Vapor flowing from both side edges, or steam generated from the stored items, is released to the outside of the container through the gap formed between the container body and the lid part, even in the closed state. Since the gap is formed by expanding the inside by the concave portion of the part, the release to the outside is promoted, so there is no closing of steam and the like, and there is no possibility of water droplets getting wet and preventing damage to the stored items be able to. Since the inclination of the top surface, the ribs in the inclination direction, the gap between the flanges, the gap between the recesses and the like can act in a correlated manner, a more preferable effect is achieved. Moreover, the gap is of a level that does not become unsanitary and can maintain practicality.
If the bottom surface of the container body is the bottom surface of the rib, the stored items can be protected from moisture that is likely to be generated on the bottom surface, so that the effect can be further enhanced.
