JP3965248B2 - Simple container for food - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a simple container for storing processed foods and taking them home.
[0002]
[Prior art]
Conventionally, as such a simple container, a thin plastic bottom material attached to the lower end surface of a plastic frame by fusing or bonding is good-looking and easy to handle. It is widely used as a take-out container for various processed foods such as sushi.
[0003]
However, various problems at the time of disposal of plastics have been pointed out, and containers using paper with few problems at the time of disposal have come to the spotlight. The applicant of the present application disclosed in Japanese Patent Application No. 10-143528 previously filed a simple container that minimizes the use of this plastic. In this simple container, a paper sheet is bent into an edge frame, and the periphery of a thin plastic bottom material is locked to the edge frame.
[0004]
[Problems to be solved by the invention]
The problem to be solved by the present invention is to further simplify the assembly of a simple container made of a frame material made of this paper sheet and a thin plastic bottom material.
[0005]
[Means for Solving the Problems]
The simple container for food of the present invention comprises an expandable bottomed paper edge frame and a thin plastic inner container, and the inner container is placed from above the paper edge frame placed with the top face up. A simple container for food that is assembled with a single touch by lightly pushing, and the paper frame is provided with an edge that is formed on the inner upper peripheral surface thereof and that is open so that the end thereof is bent. The outer periphery of the inner container is provided with a protrusion that engages with an edge of the paper-made edge frame, and is formed outwardly at a tip that extends the outer edge of the inner container downward. .
[0006]
The outer circumference of the plastic inner container is made slightly smaller than the inside of the paper edge frame, and the protrusion formed on the outer peripheral surface of the plastic inner container and the inner upper circumference of the paper edge frame By adjusting the positional relationship of the edge formed on the surface, the protrusion formed on the outer peripheral surface of the inner container is pushed into the inner peripheral surface of the edge frame by pushing the inner container from above the edge frame. A simple container can be assembled by locking to the lower end.
[0007]
Therefore, if a large number of various types of inner containers are prepared at the use site, many simple containers for the purpose of use can be easily assembled at the site.
[0008]
At that time, the paper edge frame is in the form of a developed sheet, and the plastic inner container can be placed on top of each other, so that a large storage space is not required.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to examples shown in the accompanying drawings.
[0013]
Example 1
1 to 4 show a first embodiment of the present invention. FIG. 1 shows the appearance of the paper frame 1 and the plastic inner container 2 which are respective assembly members and the outline of assembly, and FIG .
[0014]
As shown in FIG. 2 , reference numeral 1 denotes an edge frame having a bottom portion 11 assembled with a thick paperboard used in a normal paper container and glued as necessary, and the top portion 12 is not necessarily provided. However, it can be formed in a planar shape for better appearance. Reference numeral 13 denotes an end edge extending downward from the top surface 12 of the edge frame, and the end thereof is opened so as to bend .
[0016]
Moreover, about the plastic inner container 2, the protrusion part 21 is formed outward in the front-end | tip which extended the outer edge 22 of the inner container below. Accordingly, as shown in FIGS. 1 and 2, when pushed container 2 from the top to the bottom face 11 below the paper edge frame 1 placed on the floor, as shown in FIG. 3, the container 2 The protruding portion 21 is locked to the edge 13 of the edge frame of the paper frame 1 to complete the simple container 20 of the present invention. FIG. 4 shows the appearance of the completed simple container 20. In the case of this simple container 20, the assembling work is very simple because the projecting portion 21 of the inner container 2 is simply pushed into the paper edge frame 1 and locked to the edge 13 of the edge frame.
[0017]
Example 2
In the case of the first embodiment, as shown in FIG. 4 , a gap is formed between the outer edge 22 of the plastic inner container 2 and the top portion 12 of the paper edge frame 1 after assembly. This embodiment shows an example of using this as a simple container with a lid member.
[0018]
FIG. 5 shows this embodiment, in which one side of the top 12 of the paper frame 1 is extended to form a lid member 14. Thereby, it can be set as the simple container 30 with a lid | cover. And it can be set as the simple container with a lid | cover which inserts the front-end | tip of the cover member 14 in the clearance gap 3 between the outer edge 22 of the inner container 2, and the top part 12 of the paper edge frame 1. FIG.
[0019]
【The invention's effect】
The present invention has the following effects.
[0020]
1. The shape retention as a food container is maintained by the paper edge frame, so the inner container can be made of extremely thin plastic, and the edge frame is also made of paper. The amount of plastics used can be made extremely small compared to that of the product, which is environmentally friendly and can be a food container having the same function and appearance as those of conventional plastic products.
2. Assembling can be done with a single touch, reducing assembly costs.
[0021]
3. Since it can be easily assembled at the site of use, it is possible to provide containers suitable for various kinds and small amounts of processed food at the site of use.
[Brief description of the drawings]
FIG. 1 shows the outer appearance of an edge frame and an inner container constituting a simple container according to a first embodiment of the present invention.
FIG. 2 shows a cross section of the member shown in FIG.
3 shows a state after assembly of the members shown in FIG.
FIG. 4 shows the appearance of the assembled simple container of the first embodiment.
