Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a food container.

[0002]

2. Description of the Related Art In recent years, plastic containers have been frequently used as containers for storing foods, whether liquid or solid. Plastic containers are quite thin, even with water,
It has a barrier property against gas and the like, can shield the contents from microorganisms, and can be manufactured in a short time at low cost and in large quantities by injection molding, which is advantageous in terms of hygiene and production. In addition, plastics of various characteristics can be prepared according to needs, and there is no material that is superior to this at present. Here, the plastic container is generally collected after use, burned or disposed of in landfill. But,
Plastic containers are backed by their ability to retain their shape and tend to have a high volume of waste. For this reason, the disposal amount becomes large, which is a major problem. Therefore, reducing the volume of plastic container waste is a major issue.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a food container which can be easily crushed after use to reduce its volume.

[0004]

Means for Solving the Problems To achieve the above object, the invention described in claim 1 is a food container,
A plastic rib member, and a plastic wall member formed integrally with or separate from the rib member and thinner than the rib member, and a thin portion made of a member such as paper or a composite material of plastic and paper; When the thin portion is peeled or broken, a notch is provided in the rib member so that the rib member bends due to a pressing force from above with respect to the container bottom direction.

[0005]

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 4 show one embodiment of a food container according to the present invention. 1 to 3 show the configuration of a rib member 2 as a basic structural member of the food container 1. FIG. The rib member 2 is made of plastic. In this embodiment, the rib member 2 circulates in the horizontal direction.
It has a band 3 and one column 4 on each side. The rib member 2 further includes a concave bottom portion 5, and the upper portion is a peripheral portion 6 having an inverted L-shaped cross section. The band 3, the column 4, the bottom 5, and the periphery 6 are integrally formed of plastic to form the rib member 2. A plurality of windows 7 are formed by the rib members 2. The lid 8 of the food container 1 is indicated by a virtual line represented by a two-dot chain line.

Further, in this food container 1, FIG.
As shown in FIG. 5, all the windows 7 are covered with a thin portion 9 made of a thin plastic wall member. The thin portion 9 can be formed integrally with or separate from the rib member 2. In the case of integrally forming, a mold for integrally molding the rib member 2 and the thin portion 9 can be prepared, a plastic material can be introduced into the mold, and the mold can be formed by injection molding. When it is configured as a separate body, it can be configured by attaching the thin portion 9 to the rib member 2 by an appropriate bonding means such as an adhesive or heat welding. The rib member 2 includes a notch 10 which is a feature of the present invention. As shown in FIG. 5, the notch 10 is provided in a triangular cross section from the inner side of the food container 1. The notch portion 10 is for allowing the food container 1 to be easily crushed by pressure from above.

In the present embodiment having the above configuration, the food container 1
When the consumer peels or breaks the thin-walled portion 9 and applies a pressing force from above with respect to the bottom surface of the container, the rib member 2 is bent by the notch portion 10 so that the entire food container 1 can be easily formed. To crush. As a result, the volume of waste can be reduced. That is, the thin portion 9 maintains the strength of the container, and when the contents are filled, an operation such as conveyance can be performed. When this is peeled or broken, the container can be easily crushed because of the notch 10.

FIG. 6 and FIG. 7 show another embodiment of the food container 1. This food container 101 is, as shown in FIG.
A rib member 102 is provided as a basic structural member. The rib member 102 is made of plastic, and in this embodiment, two pillar portions 103 are provided vertically on the front and back sides.
, And each side is provided with one pillar 104. The rib member 102 further includes a concave bottom portion 105, and the upper portion is a peripheral portion 106 having an inverted L-shaped cross section. Then, the pillar portions 103 and 104, the bottom portion 105, and the peripheral portion 106
Are integrally formed of plastic to form the rib member 102. A plurality of windows 107 are formed by the rib members 102. The lid 108 of the food container 101 is indicated by a virtual line represented by a two-dot chain line. Here, in the food container 101, as shown in FIG. 7, all the windows 107 are covered with a thin portion 109 formed of a thin plastic wall member.

The thin portion 109 can be formed integrally with or separate from the rib member 102. In the case of integrally forming, a mold for integrally molding the rib member 102 and the thin portion 109 can be manufactured, a plastic material can be introduced into the mold, and the mold can be formed by injection molding. When it is configured as a separate body, it can be configured by attaching the thin portion 109 to the rib member 102 by an appropriate bonding means such as an adhesive or heat welding. The rib member 102 is
A notch 110, which is a feature of the present invention, is provided.
As shown in FIG. 5, the notch 110 is
01 is provided in a triangular cross section from the inner surface side. The notch 110 is provided with the food container 10 by pressure from above.
1 is to be easily crushed.

In the present embodiment having the above configuration, the food container 1
After using 01, when the consumer peels or breaks the thin portion 109 and applies a pressing force from above with respect to the bottom surface direction of the container, the rib member 102 is bent by the notch portion 110, so that the entire food container 101 can be easily formed. Crush easily. As a result, the volume of waste can be reduced. In other words, the thin portion 109 maintains the strength of the container, and enables the operation such as conveyance when the contents are filled. When this is peeled or broken, the container can be easily crushed because of the notch 110.

In addition to the above embodiment, various other embodiments are possible according to the present invention. The notch is
As shown in FIG. 8, it may be hollow. When the thin portion can be peeled off, it may be provided outside the food container as shown in FIG. Further, the position and number of the cutouts are not limited to the illustrated embodiment, but may be set as appropriate according to design requirements. When the plastic used is polystyrene or polypropylene, the thickness of the rib member is usually 0.5 mm to 0.8 mm, and the thickness of the thin portion is usually 0.1 to 0.5 mm. Further, as the material of the thin portion, plastic is preferable, but it is also possible to use paper or a composite material of paper and a plastic film.

[0012] The food container according to the present invention comprises yogurt,
It can be applied to many types of beverages such as fruit drinks.

[0013]

As is apparent from the above description, according to the present invention, there is provided a food container which can be easily crushed after use to reduce its volume.
