Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a container for noodles or soup,
In particular, it relates to a container used as tableware that can be heated in a microwave oven as it is.

[Prior art]

BACKGROUND ART Conventionally, containers used as tableware for noodles and soups include those made of synthetic resin molded products, for example, containers formed by embossing a plastic sheet and containers formed by foam molding. It has come to be sold as a product that stores this in a container.

[Problems to be solved by the device]

However, due to the difficulty of discarding the synthetic resin molded product, environmental damage caused by the synthetic resin molded product has become a problem. A paper container can be considered as an alternative, but a container having a large top opening has a disadvantage that the rigidity of the upper peripheral edge portion is insufficient. From these points, recently there is a composite container that uses a synthetic resin molded product in a part of the container, but since it is an insert molding container in which the paper part (blanks) is placed in the mold and injection molded However, there is a problem that the mold becomes large and the molding cycle of this container is long, so that the container cannot be efficiently manufactured. In view of this, the present invention aims to reduce the amount of synthetic resin used and to make it easy to process paper products, and to efficiently manufacture a container that combines synthetic resin molded products and paper products. It is an object of the present invention to provide a container that can be manufactured easily and at low cost.

[Means for Solving the Problems]

The present invention has been made in consideration of the above-described problems, and a paper container body having a grip portion formed by folding a paper product having a synthetic resin layer on the surface thereof and an engagement protruding downward from a synthetic resin molded product. And a container upper peripheral member having a portion, and provides a composite container characterized in that the pinch portion of the paper container main body and the engaging portion of the container upper peripheral member are coupled to each other to solve the above problems. is there.

[Action]

In the present invention, the frame-shaped container upper peripheral member which is easy to manufacture and the folding paper container body are divided into units in advance, and by combining these members, the composite container can be efficiently obtained.

【Example】

Next, the present invention will be described in detail based on the embodiments shown in FIGS. Reference numeral 1 in the figure denotes a composite container, and as shown in FIG.
Is a frame-shaped container upper peripheral member 2 made of a synthetic resin molded product,
The folding paper container main body 3 is composed of one blank having a bottom plate and a side peripheral plate. An upper end edge 30 of the folding paper container body 3 is heat-sealed and joined to an inner peripheral lower end edge 20 of the container upper peripheral member 2 (FIG. 3). Further, in the folding paper container body 3, a predetermined portion of the side peripheral plate is folded, and a grip portion formed by folding the side peripheral plate together.
31 is provided, and the knob 31 is provided on the container upper peripheral member 2
It is fitted into the engaging portion 21 provided on the container to position and stiffen the container upper peripheral member 2 (FIG. 4). 5 to 8 show a second embodiment. In the second embodiment, a bag-shaped grip portion 32 is provided at a predetermined position on the side peripheral plate of the folding paper container body 3, and a corresponding insertion piece 22 is provided on the container upper peripheral member 2 in accordance with this. The insertion piece 22 is inserted into the picking portion 32 (FIG. 8), and as described above, the folding paper container main body 3 is fitted to the inner peripheral lower end edge 20 of the container upper peripheral member 2.
The upper edge 30 of each is heat-sealed and joined. Reference numeral 4 in the figure denotes a lid member. As a material of the synthetic resin molded product that becomes the container upper peripheral member 2, an olefin resin is preferable, and when the container needs to have rigidity, high density polyethylene can be adopted. Further, the paper product forming the folding paper container body 3 is a laminated material having a synthetic resin layer on the surface thereof so as to have a heat-sealing property, such as polyethylene / paper / polyethylene, polyethylene / paper / polyester / polyethylene, polyethylene. In addition to a sheet member having a layer structure such as / paper / aluminum / polyester / polyethylene, a material obtained by extruding a film having a heat-sealing resin into a film and laminating it on a paper material may be used. As described above, the container upper peripheral member 2 is made of a synthetic resin molded product. For example, a handle having a laterally protruding shape or a handle which can be raised by a self-hinge can be integrally molded. In addition, in the above-mentioned embodiment, the pan-shaped container is exemplified, but various shapes such as a container having a deep bottom can be adopted as the container.

[Effect of device]

As described above, according to the present invention, a composite container is a combination of a folded paper container body formed by folding a paper product having a synthetic resin layer on its surface, and a container upper peripheral member made of a synthetic resin molded product. Therefore, the proportion of the synthetic resin molded product in the entire container is small, and the process can be simplified without increasing the cost. In addition, the folding paper container body made of paper products can be printed, etc., and the container upper peripheral member having a complicated shape can be formed of synthetic resin that is easy to mold, so that the functionality and commercialability of the container are not impaired. . Furthermore, the upper peripheral member of the container and the folded paper container body each have a simple shape and can be efficiently molded. Therefore, by combining these, a large container can be efficiently manufactured and the cost can be reduced. And so on, the effect is excellent in practicality.
