Description

[Detailed description of the invention] [Industrial application field] This invention relates to packaging containers, particularly packaging containers that can be manufactured simply and inexpensively, and that can create a luxury or expensive atmosphere for the product being packaged. It is something.

[Conventional technology and its problems]

For example, conventional packaging containers for packaging sweets such as Chiyocolate were usually formed from a box-shaped main body and a lid covering the main body.

On the other hand, packaging containers are an important element for increasing product value, but if they are too elaborate to give a luxurious or expensive feel, the manufacturing cost will be high. Therefore, packaging containers must be able to give off an expensive or luxurious feel in relation to the product, and must also be able to be manufactured at low cost.

Therefore, a packaging container disclosed in Japanese Utility Model Application Publication No. 50-53304 has been devised. That is, as shown in FIG. 6, a bottom plate 21 covering the opening is arranged in a bendable manner on one edge of the opening of a box-shaped lid 20 made of paper, and a storage body 22 made of synthetic resin is attached to this bottom plate 21. There is a container.

This container is made of synthetic resin and can be easily decorated with various colors and other decorations.
Its rising wall is wide, and when the lid is opened,
Since the outer surface of the rising wall is completely exposed, it can create an expensive or luxurious feel that cannot be achieved with paper alone.
It has the effect of increasing product value.

However, since the lid 20 and the bottom plate 21 are integrated, when attaching the storage body 22 to the bottom plate 21,
The lid gets in the way, and it is necessary to hold the lid 20 in an open state. In addition, the components of the lid 20 are heavier than the bottom plate, so the bottom plate 21 lifts up, making it difficult to quickly and accurately place the storage body 22 in the specified position. It is difficult to apply the container, and furthermore, the lid 20 must be kept open until the adhesive dries and the adhesive state is maintained regardless of external force, resulting in poor workability in assembling the container.

[Purpose of invention]

The purpose of this invention is to provide a packaging container with a plastic storage body that is easy to assemble and is easy to assemble.

[Means to achieve the purpose]

In order to achieve the above object, the packaging container of this invention has a structure in which the storage body is fixed to the bottom plate, and then the bottom plate with the storage body can be attached to the lid by fitting. It consists of a square box-shaped paper lid with a peripheral wall around the entire circumference, a paper bottom plate that covers the bottom surface of the lid, and a plastic storage body fixed to the top surface of the bottom plate. The opposing side walls have a double structure consisting of two plates, and each of the inner plates of the side walls has a cutout that is open at the edge thereof, and a notch is formed at the edge of the inner plate of the side wall. A connecting plate and an inner plate are successively bent inwardly at right angles through folds on the edge corresponding to one side wall, and the connecting plate fits exactly between the two side walls. A locking piece is set to the same size as the inner surface of the one side wall and is bent inward at right angles to fit into the notch through a fold at both ends thereof, and the inner plate is formed with a lid. Furthermore, the peripheral wall of the lid has a height that covers the rising wall of the storage body from the outside, and the inner plate is set within the peripheral wall. The connecting plates are fitted along the upper plate and along the one side wall, and the locking pieces are fitted into the notches.

In a packaging container constructed in this way, after the storage body is fixed to the bottom plate, the connecting plate and the inner plate are placed inside (the side of the storage body).
Bend it and fit it into the lid, and fit the locking piece into the notch to assemble.

〔Example〕

Embodiments of this invention will be described below with reference to the accompanying drawings, FIGS. 1 to 5.

As shown in FIG. 1, the packaging container consists of a combination of a rectangular box body A made of paper and a storage body B made of plastic. This box body A has a square box-shaped lid 2 having a peripheral wall 1, and a bottom plate 4 with a locking piece 3.
It is configured such that it is foldably locked.

The lid 2 is made of base paper as shown in FIG.
That is, a side plate 6, a pasting plate 6', a connecting plate 7, and an end plate 8 are successively provided on each edge of the square upper plate 5 via a fold a. A locking notch 9 is formed at both ends of both pasting plates 6', and a locking piece 10 that fits into the locking notch 9 is formed at both ends of the end plate 8.
Furthermore, a notch 11 into which a locking piece 3 for connecting the bottom plate 4 is fitted is formed inwardly from the edge at one end of both pasted plates 6'.

Next, as shown in FIG. 4, each plate 6, 6',
7 and 8 through the fold a, and attach the pasting plate 6' to the side plate 6.
A peripheral wall 1 consisting of four side walls 1a, 1a, 1b, 1b is formed by the pasting plate 6', side plate 6, side plate 6, and connecting plate 7, and the peripheral wall 1 is formed by two plates 6, 7.
To obtain a lid 2 having a double structure consisting of 6 and 6' and having a notch 11 opened at the same end of an inner plate 6' of a side wall 1a serving as a long side wall.

On the other hand, the bottom plate 4 has the same size as the bottom surface of the lid 2,
As shown in FIG. 5, a connecting plate 13 and an inner plate 14 are successively provided along the entire length of the short edge of the plate 12 which becomes the bottom plate 4 through a fold a, and at both ends of the connecting plate 13. , the locking piece 3 that is locked in the notch 11 is formed through the fold a. The connecting plate 13 is set to have the same size as the inner surface of the side wall 1b that fits exactly between the side walls 1a, and the inner plate 14
is set to have the same size as the inner surface of the upper plate 5 that fits exactly inside the lid 2.

The storage body B is provided with a wide rising wall 15 around its periphery, and is usually made by vacuum forming. This storage body B is, for example, given an appropriate coloring, or the surface thereof is subjected to a flocking treatment. Further, as shown in the figure, partition walls 16 are formed in the storage body B depending on the shape and size of the product.

Note that the peripheral wall 1 of the lid 2 is formed at a height that covers the outer surface of the rising wall 5 of the storage body B.

The storage body B is integrally fixed to the upper surface of the bottom plate 4 by adhesive or heat sealing.

The bottom plate 4 to which the storage body B is fixed is obtained by bending the connecting plate 13 and the inner plate 14 inward (toward the storage body B side), and then attaching both plates 13 and 14 to the lid 2 along the connecting plate 7 and the top plate 5. The locking piece 3 bent inward is fitted into the notch 11, and the inner plate 14 presses the locking piece 3 toward the peripheral wall 1 to ensure the fitting, and the bottom plate 4 is joined to the lid 2. do. At this time, as shown in FIG. 2, if a part of the locking piece 3 is sandwiched between the side plate 6 and the affixing plate 6', the connection becomes even more reliable.

In the container configured in this way, the locking piece 3 fits into the notch 11 and the locking piece 3 is fitted into the notch 11 by the inner plate 14.
is in pressure contact with the peripheral wall 1, so even if the locking piece 3 tries to come off, it will come into contact with the periphery of the notch 11 and will not come off.
Therefore, the bonded state between the bottom plate 4 and the lid 2 is maintained.

[Effect of idea]

This invention is constructed as described above, with the opposing side walls 1a, 1a of the lid 2 having a double structure consisting of two plates, and the inner plates 6', 6' of both side walls 1a, 1a having the same structure. Since the notch 11 was formed at the end,
A recess consisting of a notch 11 is formed on the inner surface of the end portion of the side walls 1a, 1a, and the connecting plate 13 just fits between the both side walls 1a, 1a, and the locking pieces 3 at both ends thereof
By bending the inner plate 14 inward and fitting it into the recess, the connecting plate 13 is attached to the lid 2 by this fitting, and by fitting the inner plate 14 into the lid 2, the connecting plate 13 is attached to the lid 2. Therefore, the locking piece 3 is pressed against the lid side walls 1a, 1a and does not come out of the notch 11, and the inner plate 14 is supported by the lid 2, and the inner plate 14 is supported and the locking piece 3 is fitted to the lid 2. By attaching the connecting plate 13 to the lid 2 by fitting both plates 1
A bottom plate 12 connected to parts 3 and 14 is supported by the lid 2. For this reason, after fixing the storage body B to the bottom plate 12, by bending the connecting plate 13 and the inner plate 14 inward (toward the storage body side) and fitting them into the lid 2, and fitting the locking piece 3 into the notch 11, The packaging container according to this invention can be easily assembled.

Therefore, according to this invention, the storage body B can be fixed to the bottom plate 4 with the inner plate and the connecting plate in a flat state by gluing, etc., and can be left as is until the adhesion is ensured. Unlike the conventional device shown in FIG. 6, there is no need to keep the lid open. Furthermore, the bottom plate 4 can be easily attached to the lid 2 by fitting. Therefore, although the packaging container according to this invention requires more man-hours to assemble compared to the one shown in FIG. 6, it can be said that the packaging container has good assembly workability overall because the lid does not have to be kept open.

Furthermore, even when changing the design of a container due to the diversification of consumer needs, if the container lid and storage body are integrated, it is necessary to change the lid along with the storage body, but with this idea, the lid and storage body are Because they are manufactured separately, the design can be changed simply by changing the lid, which makes up the majority of the container's appearance, making it possible to save resources and manufacture containers at low cost without wasting the materials of the storage body. It is what it is.
