The structure of the present invention will be explained according to the drawings. Fig. 1a is an exploded plan view of the lid, Fig. 2b is an exploded back view of the lid, Fig. 2 is an exploded explanatory view of the lid, inner case, and container. Figure 3 is a perspective view of the completed assembly.

In the drawing, A ₁ is a lid, and long walls 4 a and 4 b and short walls 5 a and 5 b are connected to each other on the four sides of a rectangular surface portion 1 through folds 3 .

Reference numeral 6a denotes a strip-shaped opening section in which a knob 7 is attached to one end in the longitudinal direction of the long wall section 4a, and a cutting line 8 is provided oppositely so that the opening can be cut to an arbitrary width. This band-shaped opening part 6a is narrow near the center, and the insertion piece 9
is formed.

P ₁ is an opening guide line provided on both the left and right sides of the front surface part 1, and in FIG. Continuous on both left and right ends.

In addition, in FIG. 1b, the areas marked with coarse and dense halftone dot patterns m and n respectively illustrate the setting positions of glue or other adhesive parts, or heat-sealed parts.

Adhesive parts m at the back side ends of the long wall parts 4a, 4b and the short wall parts 5a, 5b are attached to the outer peripheral wall of the container C, which will be described later, and a heat seal part n is provided around the back surface of the front part 1. There is. Interior case B ₁ (described later)
If the area is partitioned by a partition plate, a heat seal portion is formed corresponding to the upper surface of the partition plate.

In addition, the lid bodies A ₂ and A ₃ illustrated in FIGS. 4 and 8
Similarly, an adhesive or a heat sealant may be applied to the back surface of the container, which contributes to the mass production of the container as contemplated by the present invention. Preferable materials for the lid include plastic laminated boards, plastic aluminum boards, aluminum laminated boards, aluminum laminated boards, and laminate films.
As a result of the above-described structure of the lid according to the present invention, the interior case, which will be described later, can be fixed to the lid using a normal heat-sealing section or by applying hot melt to the adhesive section of the lid. It is also possible to coat the adhesive layer with a low-temperature sealing property and perform low-temperature heat sealing.

B ₁ is, for example, polyethylene, polypropylene,
An interior case made of materials such as polystyrene, polyvinyl chloride, thermoplastics, laminated aluminum foil, laminated film, paper, etc., and the opening edge is fixed to the back surface of the lid _A1 . The peripheral edge 10 is formed to be flexible.

C is a container, which is suitably fitted with a lid A 1 by known manufacturing means, such as a plug-in, glue-on or built-in assembly box, machine box or folding box, as illustrated in _FIG . A bottom part 2 having approximately the same shape as the surface 1, long walls 4a and 4b continuous to the periphery of the lid body _A1 , and a peripheral wall part 11 having approximately the same shape as the short walls 5a and 5b are formed.In short, it is an interior case. B ₁
It is sufficient that the height of the peripheral wall 11 of the container C is within a range where the bottom part of the container C does not come into contact with the bottom surface 2 of the container C and is crushed, and the height of the peripheral wall 11 of the container C is suitable for accommodating the inner case. In addition, the long wall portions 4a, 4b and the short wall portions 5a, 5 of the lid body _A1.
b is fixed to the outer surface of the peripheral wall of the container C.

The instructions for using and assembling the composite container according to the present invention will be described with reference to FIGS. 1 to 3.
First, desired contents are stored and filled into the inner case.

Next, the lid body made of the above-mentioned material has adhesive or heat sealing agent applied to its back surface,
What is necessary is to close the opening of the inner case made of the above-mentioned material using the above-mentioned fixing means.

The periphery of the back surface of the front surface of the lid is fixed to the periphery of the opening of the inner case, and the long walls 4a, 4b and short walls 5a, 5b are affixed to the outer surface of the peripheral wall 11 of the container C, completing the composite container. (See Figure 3).

The completed composite container is opened by tearing the band-shaped opening part 6a formed on the long wall part 4a from the knob 7, and then following the opening guide lines P ₁ and P ₁ formed on both sides of the surface part 1. .

This makes it possible to take out the contents from the interior case _B1 . After removing the contents, insert the insert piece 9.
It is possible to reseal the container by inserting it into a notch (not shown) made in the peripheral wall of the container.

The present invention has other embodiments as follows regarding its configuration.

That is, FIGS. 4 to 7 show other embodiments, FIG. 4a is a developed plan view of another lid, and FIG. 4b is a developed plan view of another lid.
5 is an exploded explanatory view of another lid, another inner case and container, FIG. 6 is a perspective view of the completed assembly based on FIGS. 4 and 5, and FIG. 7 is an exploded rear view of another lid. The figure is an explanatory diagram of the usage state of Fig. 6, Fig. 8 a and b are both partially developed plan views of other lid bodies, and Fig. 9 is an explanatory view of the use state of Fig. 8.
Explanatory diagram of usage state when using the lid shown in Figure b, No. 10
Figures a and b are both partially developed plan views of other lids.

In addition to the opening guide line _P1 , a pair of opening guide lines _P2 may be provided in correspondence with the opening guide line P1 at approximately the center of the surface portion ₁ (at a position corresponding to the upper surface of the partition plate of the inner case).

In this case, the surface portion 1 divided left and right by the guide lines P ₁ and P ₂ is an opening portion that is exposed when the user first cuts out the band-shaped opening portion 6a and then follows any guide line. You can freely choose whether to unveil the whole thing or just one side.

If this technical idea is followed, the interior case B ₁ without a partition may be replaced with a dual-type (two-part) interior case B ₂ having compartments.

Of course, this is not limited to the above, but it is also possible to further increase the opening guide lines of the lid A ₃ as P ₃ and P ₄ and provide them as shown in Figure 8a, and accordingly, a triple-type (three-division) inner case (not shown) may be provided in accordance with the setting means, and the band-shaped opening portion 6b
is constructed in a modified manner as shown in Figure 8a.

As another embodiment, as shown in FIG. 8b (the case of lid _A2 is illustrated), the band-shaped opening portion 6c is not limited to the long wall portion 4a, but may include the long wall portion 4b and the short wall portions 5a, 5b.
(In this case, the knob 7 can be omitted as shown in the figure.) As shown in FIG. 9, the lid body A ₂ can be separated from the container C with the inner case B ₂ attached. The bottom surface part 2 of can be exposed.

In this case, although not shown in the drawings, it is possible to appropriately print on the surface of the bottom portion 2 (for example, articles on how to prepare or eat food as contents, and other information).

In addition, as another embodiment, in addition to providing the opening guide line along the peripheral edge 10 of the inner case _B2 , if the opening guide line _P5 shown in FIG. In addition, if an opening guide line _P6 is provided, it will be cut out into a unique shape that looks good. Similarly, the modified opening guide line _P7 can also be used as a drawer opening.

In the shape of the composite container of the present invention described above, during the manufacturing process, the lid A and the container C are separate bodies, and by making them separate, a special effect as described below is brought about. Even when the two are connected in a so-called hinged box format (not shown), the main effects can be fully exerted.

In FIG. 2, a notch is provided in the peripheral wall portion 11 of the container C corresponding to the insertion piece 9 formed by the perforation line 8 in the long wall portion 4a of the lid body 1, and a notch is provided in the peripheral wall portion 11 of the container C as illustrated in FIG. In the case where a plurality of opening portions are formed by opening guide lines and a plurality of insertion pieces are formed together with the opening portions, corresponding notches may be provided in the peripheral wall portion 11.

The present invention having the above configuration brings about the following effects.

First, the most important feature of the present invention is that the lid is not only a lid for the inner case, but also a lid for closing the opening of the container.

Therefore, the act of opening the lid leads to the disclosure of the previously sealed contents, so to speak, it is simultaneous opening, and unlike conventional products, it is attached to the opening of the inner case regardless of the outer box. This eliminates the trouble of peeling off a separate cover material such as plastic film, which contributes to a reduction in material costs.

Second, in what was called a conventional sealed carton with a plastic tray, the lid and container were, in principle, of the same format, so the paper materials that made up the lid and container were also made of the same material. Therefore, the manufacturing cost tends to be high.

However, the present invention is to separate the lid A and the container C, and since most of the container C except for the bottom 2 is covered by the lid A, for example, if the container C is the lid A ₁ , A ₂ , and A ₃ can be used, which is thinner and cheaper, which contributes to reducing production costs.
