Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention mainly relates to a food container formed by forming unevenness into an appropriate shape using a chlorine-free resin material.
[0002]
[Prior art]
More specifically, the food container mentioned here is a container for packaging chicken eggs and quail eggs, a container for packaging small fruits and vegetables such as strawberry and strawberry, mini tomatoes, loquat, and kumquat, and a container for packaging Japanese and Western confectionery. , PET bottles, liquid beverage containers, bean sprouts, Japanese radish, mushrooms, boiled vegetables and other deep vegetables, deep dish or deep cylinder type containers, tofu, natto, pudding and other food packaging There is a dish-shaped container for use.
[0003]
At present, these food packaging containers are mainly made of polyethylene terephthalate (PET) resin material, and are formed by a well-known compressed air / vacuum molding means, continuous blow molding means, and injection molding means. Various shapes are formed according to the shape and shape.
[0004]
Thus, on these resin molded containers, the names of the contained foods, the names of the producers, and other advertising items necessary for sales promotion were designed on the outer surface including the bottom surface of the containers, or the required display of only the typeface was made. Labels or stickers are affixed, or the heat-shrinkable film is heated and shrunk to make it adhere to the outer periphery of the container (these are collectively called a label, which is referred to as sticking). After being housed and sealed, these labels are applied and the goods are shipped to the market.
[0005]
Such various containers are discarded as unnecessary after use of the contained food. Discarded containers are collected and reused from the viewpoint of effective use of resources.However, not only is the cost of collection expensive but also most of the collected waste containers are different from the container material. At present, the label formed of the resin material described above is not suitable as a reusable resource because the label is attached to a container. Therefore, most of the discarded containers are currently incinerated and dumped underground.
[0006]
[Problems to be solved by the invention]
One of the main reasons why the collected containers mentioned here are not suitable as reusable resources is that the label made of a resin material different from the container material remains attached to the container as described above. Therefore, it is difficult to obtain a high-purity recycled PET resin material.
[0007]
It is considered that the main reason that the collected containers are often discarded with the label attached is that it is difficult to separate and remove the containers. In order to remove the label from the collection container, a lot of manpower is required. The reason why it takes time to remove the label seems to be that it is difficult to touch the fingertip to one end of the label when peeling the label, it is easily torn off even if it is peeled off with a toe, it can not be peeled off quickly and it takes time and effort It is.
[0008]
Therefore, the present invention aims to fundamentally solve the problem that the conventional food container has, and even the individual user of the container can remove the label from the collection container by hand. However, it is an object of the present invention to provide a food container that can easily and easily remove the label attached to the container and can sufficiently cope with the reuse of the container.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the food container of the first configuration of the present invention, which is provided on the label attaching surface 2 of the food container 1 formed of a non-chlorine-based resin material, has a label 3 It is configured to include a fingertip insertion concave portion 4 that is continuously recessed from outside the region to inside the region.
