Description

[Detailed description of the invention] <Technical field> This invention relates to an assembly type container. More specifically, the present invention relates to an assembly type container that is a combination of a peripheral frame made of a synthetic resin sheet and an inner container.

<Background and Prior Art> Conventionally, in the case of folding box containers, many assembling type containers made of synthetic resin sheets have been provided instead of wooden ones made of warp wood or the like.

These synthetic resin sheet assembly types are
Mainly, it is assembled by joining the bottom plate to the peripheral frame with adhesive or by fitting the bottom plate into the inner circumferential groove of the peripheral frame, but when using adhesive bonding, the assembly work is troublesome and time-consuming. In addition, there is a problem that the liquid juice of the stored food leaks from the bottom of the container that fits into the inner circumferential groove. In addition, adhesive bonding is unfavorable from a sanitary point of view, and
Since they are not suitable for assembly at the site of use and are mostly provided pre-assembled in factories, they are bulky and difficult to handle during transportation and storage, and transportation costs are also high.

In addition, the inner container, which is integrally molded and has a hook-shaped flange protruding outward on the opening edge, is attached to the locking part of the upper edge of the peripheral frame formed by bending the peripheral side material in the form of a strip. There was a structure in which the inner container was stored inside the peripheral frame so that the liquid juice of the stored food would not leak outside (see Japanese Utility Model Publication No. 177925/1983), but Forming the hook-shaped flange, which is composed of an extending overhang and a bent portion that bends from the overhang and extends downward, is extremely troublesome and requires manufacturing time, which increases the cost of the container. During use, the hook-shaped flange may break off at the base, causing problems such as the risk of the stored food scattering outside the container.

<Purpose> This invention was made in view of the above problems, and is easy to assemble, suitable for assembly at the site of use, convenient for transportation and storage, and prevents liquid juices from leaking from stored foods, etc. The purpose is to provide an assembly type container.

<Configuration> The configuration of this invention to achieve the above object includes a peripheral frame formed by bending a peripheral plate made of a synthetic resin sheet, and an inner container that can be stored inside the peripheral frame. An inner circumferential groove is formed in the middle of the inner circumferential wall of the circumferential frame, and the inner container has a mouth edge projecting outward in a substantially horizontal manner along with the formation of the circumferential frame. It is characterized by being fitted and fixed into the inner circumferential groove and housed inside the circumferential frame.

<Example> Next, an example of this invention will be illustrated below with reference to the drawings.

Reference numeral 1 denotes a peripheral side frame, which is formed by bending a band-like sheet 11 made of a synthetic resin sheet such as foamed polystyrene at appropriately cut bending grooves 12, and forming a rectangular frame. A thin material 13 such as a synthetic resin film printed with a wood grain pattern etc. is laminated on the outer surface of the band-shaped sheet 11 constituting the peripheral frame 1 (see Fig. 3) to enhance the appearance. There is.

Next, reference numeral 2 denotes an inner container mounted within the peripheral frame 1, which is formed into a shallow container shape by press forming a synthetic resin sheet such as foamed polystyrene using a known method such as vacuum forming or pressure forming. In the case shown in the figure, a partition 21 is suitably formed integrally so as to be suitable as a lunch box container. The inner container 2 has a mouth edge 22 formed to protrude outward in a substantially horizontal manner and is fixed by being fitted into an inner circumferential groove 14 formed halfway on the inner circumferential wall of the circumferential frame 1. As for this stationary state, in addition to the case where the lower end of the peripheral side frame 1 and the bottom part 23 of the inner container 2 are flush with each other as shown in the figure, the bottom part 23 of the inner container 2
3 may be made into a suspended shape. The inner container 2 is formed so that the mouth edge 22 is wider than the bottom 23 and flares upward so that the inner container 2 can be stacked individually in multiple stages. Of course, the partition 21 is raised narrowly upward so that it can fit into the back side of the partition 21 of the inner container 2 in the stacked upper part. Note that this may be carried out by laminating a thin body made of synthetic resin film or the like with a pattern printed on the inside of the inner container 2.

To assemble and form the folded box-like container described above,
Insert the inner container 2 into the inner peripheral groove 14 of the peripheral side frame 1 in the expanded state.
Insert the mouth edge 22 of the
It is only necessary to join the parts 5' mainly by heat fusion bonding or adhesive bonding to form a frame, and it is very easy to assemble and use at the site of use.

The above-mentioned container can be used as a boxed lunch container by covering it with a lid, and can also be used alone as a container for various foods.

In addition to the above-mentioned foamed polystyrene, the materials for the peripheral frame 1 and the inner container 2 include polyethylene,
Foamed sheets made of various resins such as polypropylene can be used, and in some cases, non-foamed synthetic resin sheets can also be used.

<Effects> According to the assembled container of this invention constructed as described above, an inner container formed of a synthetic resin sheet is mounted inside a circumferential frame formed by bending a synthetic resin sheet. Because it is a container, there is no need to worry about the liquid juice of the food stored in the inner container leaking from the bottom, and it is suitable not only for use as a container for lunch boxes, but also as a container for storing food containing a large amount of liquid liquid. It can be used as a container with a wide range of uses.

In addition, the inner container has a mouth edge formed to protrude outward in a substantially horizontal manner and is fitted and fixed in the inner circumferential groove of the circumferential frame when the circumferential frame is formed, and is housed inside the circumferential frame. Therefore, the inner container can be attached simply by assembling the peripheral frame.
It is very easy to assemble and form, making it suitable for assembly at the site of use, and when transporting and storing, it is possible to unfold the peripheral frame and stack the inner containers on top of each other, making it easy to handle without being bulky. This has the advantage of requiring less storage space.

Furthermore, since the mouth edge formed to protrude outward of the inner container in a substantially horizontal manner is fitted into an inner circumferential groove formed in the middle of the inner circumferential wall of the circumferential side frame and fixed, the above-mentioned conventional content is Compared to a structure in which an outwardly protruding hook-shaped flange formed on the opening edge of the vessel is hooked to a locking part on the upper edge of the peripheral frame, it saves material, is easier to manufacture, and is less expensive. It can be manufactured at.
Furthermore, even if an adhesive is used for the frame of the peripheral frame, there is no direct contact between the stored food and the adhesive, which is also suitable from a hygienic standpoint. Furthermore, the combination of the circumferential frame and the inner container has the advantage that a pattern, etc. that is difficult to express in a molded inner container can be expressed on the circumferential frame, thereby improving the appearance of the container as a whole.

Therefore, it is possible to provide a product that is easy to assemble, is suitable for assembly at the site of use, is convenient for transportation and storage, and has various excellent practical effects.
