Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple synthetic resin food container suitable for storing foods for take-out, which is wrapped and wrapped.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Utility Model Publication No. 59-118.
No. 88, a simple container for foods, in which a lid made of a synthetic resin thin plate is fitted to a container body in which a bottom plate of a synthetic resin thin plate is heat-sealed to a foamed resin frame body by heat fusion. After the food is stored in the main body and the lid is fitted, the entire container is wrapped with a wrapping film also as a retaining function to prevent the lid from coming off.

The wrapping film wrapping is convenient because the work itself is simple and no special locking mechanism is required for fixing the lid. On the other hand, on the other hand, in the case of a lid formed with knobs protruding outward at the corners of the lid in order to make it easy to remove the lid from the container body, when the entire container is wrapped with a film for wrapping, the protrusion is outward There is a problem that the edge of the pick pulls the film locally strongly, and the film is easily torn from this part. Also, it takes time for the user to remove the wrapped film,
It gives a troublesome feeling.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a means for preventing tearing of a film during wrapping in such a simple container for food and eliminating the inconvenience of removing the film during use. To do.

[0005]

According to the present invention, referring to the attached drawings, a bottom plate 4 made of synthetic resin is fused to a lower end surface of a frame member 3 made of foamed resin having a groove 31 formed on an outer surface thereof. Container body 1
And a concave portion 23 that fits into a groove 31 provided on the outer surface of the frame member 3 of the container body 1 is formed in the hanging portion 22 of the peripheral edge 21, and the lower portion of the hanging portion 22 is formed at least at one corner. In a simple container for food for wrapping, which comprises a lid 2 made of a thin synthetic resin and having a knob portion 5 projecting outward, a knob portion 5 provided at least at one corner of the hanging portion 22 of the lid 2. The protruding edge 5a of the
It is characterized in that it is made continuous with the lower end of the hanging part of the other part not provided, and that the hanging part is inclined outward toward the lower side.

The container may have a planar shape such as a quadrangle or other polygonal shape.

The knob portion formed on the lid is sufficient at one location on the peripheral edge, but may be formed at two or more locations. Is the inclined surface formed from the edge of the knob part to the hanging part continuous from the edge of the knob part to the upper edge of the lid peripheral edge, or is it formed from the edge of the knob part to the intermediate height position of the hanging part? , Either is acceptable.

[0008]

In the simple container for food of the present invention, since the inclined surface is formed from the edge of the knob portion of the lid to the hanging portion, when the entire container is wrapped with the film for wrapping, the film follows the inclined surface. Since the film is wrapped around the edge of the picked part, no strong local tensile force is applied to the film.

Further, the film after packaging has a gap between the edge of the knob and the frame material of the container body, or between the edge of the knob and the hanging part of the peripheral edge of the lid,
The film can be easily broken by pressing the tip of a nail, a toothpick, a pen point, etc. at the time of use, and the film can be easily peeled from the container.

Further, in the packaging, the same wrapping work as in the conventional case can be performed, and the simple wrapping work can be performed without changing the conventional working method.

1 is a perspective view showing a simple container according to a first embodiment of the present invention, and FIG. 2 is a partial sectional view showing a state in which the entire container is wrapped with a wrapping film.

The container body 1 is formed by bonding a synthetic resin bottom plate 4 to the lower surface of a foam synthetic resin frame member 3 by heat fusion.

The frame member 3 is formed by bending a strip-shaped member made of foamed synthetic resin having a thickness of 3 to 5 mm into a rectangular shape, and has a groove 31 parallel to the upper edge formed on the upper portion of the outer side surface. .

The bottom plate 4 is formed by molding a thin synthetic resin sheet. A partition may be provided on the bottom plate 4.

The lid 2 is formed by molding a thin synthetic resin sheet, and has a concave portion 23 formed in a hanging portion 22 of a peripheral edge 21 to be fitted in a groove 31 formed on an outer surface of the frame member 3. The concave portion 23 may be formed on the entire circumference of the peripheral edge 21, but it is sufficient to form only the central portion and the corner portion of each side.

In this lid 2, a knob 5 is integrally formed at one corner of the lid 2 by protruding the lower portion of the hanging portion 22 outward.

In the picking portion 5, the projecting edge 5a is continuous with the lower end of the hanging part of the other part, and the upper surface is continuous with the hanging part of the other part and is inclined obliquely to the upper edge of the corner part. is doing. As described above, in this embodiment, since the picking portion 5 is projected and the upper surface of the picking portion 5 is continuous with the upper edge as the inclined surface 5b, the whole container is wrapped with the film F as shown in FIG. When wrapped with, the film F wraps around the edge 5a of the knob 5 along the inclined surface 5b, and
A gap S is formed between the edge 5 a of the grip portion 5 and the frame member 3 of the container body 1.

Therefore, when the entire container is wrapped with the wrapping film F, a strong local pulling force is not applied to the film F and the film F is not broken. Also,
Although the film F will not be torn in a normal state after being packaged, the film F in the gap S part is torn, a toothpick,
The film F can be easily broken by pressing a pen tip or the like, so that the film F can be easily peeled from the container at the time of use.

FIG. 3 is a partial sectional view showing a state in which the entire container in the second embodiment of the present invention is wrapped with a wrapping film.

In this embodiment, an outwardly projecting knob portion 6 is formed at one location on the hanging portion 22 on the periphery of the lid 2, and an inclination is made from the edge 6a of the knob portion 6 to an intermediate height position of the hanging portion 22. The surface 6b is formed. This intermediate height position is not particularly limited, and in the case of the present embodiment, the inclined surface 6b is formed in the lower portion of the concave groove 23.

Also in the case of this embodiment, as in the case of the first embodiment, when the whole container is wrapped with the wrapping film F,
The film F has an edge 6a of the knob 6 along the inclined surface 6b.
Wrapped around the edge 6a of the knob 6 and the container body 1
Since there is a gap Sa between the frame material 3 and the edge 6a of the knob 6 and the hanging portion 22 of the lid 2, when the entire container is wrapped with the wrapping film F, the film Sa F does not tear, and the film F in the gap Sa portion or the gap Sb portion is easily broken by pressing a tip of a nail, a toothpick, a pen tip, or the like, and the film F can be easily peeled from the container at the time of use. You can .

[0022]

The simple container for wrapped food of the present invention has the following effects.

Since the inclined surface is formed from the edge of the knob portion of the lid to the hanging portion, when the entire container is wrapped with the wrapping film, the film is wound around the edge of the knob portion along the inclined surface. As a result, the film is not broken because no strong local tensile force is applied to the film.

After the container is wrapped with the film for wrapping, a gap is formed between the edge of the knob of the lid and the frame material of the container body, or between the edge of the knob and the hanging portion of the edge of the lid. Therefore, when the tip of a nail, a toothpick, a pen tip, or the like is pressed against the gap, the film is easily broken and the film can be easily peeled from the container.

Without changing the conventional work method,
The same wrapping work as in the past can be performed.
