Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a box whose lid can be easily opened and whose contents are used as a packaging material for tyokolate and the like.

(Prior Art) A conventional example of a box that is easy to take out will be explained with reference to FIGS. 8, 9, and 10. The box has one side wall of a cylindrical part missing, and a side wall facing the missing one side wall. an inner box which is a cylindrical body which is separated by a body 32 and a lid body 33 except for a hinge part 34 and has a top plate and a bottom plate;
It consists of an outer box 31 which is a cylindrical body without a top plate or a bottom plate. To take out the contents in this conventional example, push up the bottom of the box shown in FIG. 8, take out the lid 33 of the inner box from the outer box 31 as shown in FIG. The contents were taken out by bending the lid 33 from 34.

(Problems to be solved by the invention) In the above-mentioned conventional box (prior art), it is necessary to bend the lid after pushing up the bottom, and it is not possible to easily take out the contents with one hand. I couldn't do it.

(Means for solving the problem) The inner box has a top plate and a bottom plate, and the cylindrical part is separated except for one side wall where the hinge part 13 of the lid body 12 is located, and the body 11 and the lid body are separated. The upper connecting piece 14, the lower connecting piece 15, and the occlusal piece 16 are connected in this order from the upper end of one side wall which becomes the hinge part 13, and the length in the extending direction of the connecting upper piece 14 is the same as that of the lid. body 12
The height of the side wall is approximately the same as the height of the side wall, and the interlocking piece 16 is completely folded back to the outside from the connecting lower piece 15, and the outer case has a part of the cylindrical body without a top plate and a bottom plate as a push-up hole 23. It is a cylindrical body in which a folding piece 22 is folded back inward from the upper end of the side wall corresponding to one side wall which becomes the hinge part 13 of the inner case, and is connected to the inner case's engagement piece 16 and the outer case. folding piece 22
The inner box is attached to the outer box so that it can move up and down.

(Function) When the inner case is pushed up through the push-up hole, the lid body rotates about the hinge part at the same time as the inner case is pushed up and automatically enters the open state.

(Example) An example of the present invention is shown in Figures 1, 2, and 3.
This will be explained in detail using FIG. 4, FIG. 5, FIG. 6, and FIG. 7.

The box of this example is made up of an inner box and an outer box.
It consists of a box part 21 with a holder and a folded piece 22.

The inner box at this time is divided into a body 11 and a lid 12 with the body of the box apart except for the hinge part 13. Further, a tongue-shaped body is connected to the upper end of the lid body 12 on the side of the hinge portion 13, and this tongue-shaped body is freely divided into three parts that can be bent in parallel. These three parts are, in order from the part closest to the lid body 12, the connecting upper piece 14,
They are a connecting lower piece 15 and an occlusal piece 16.

On the other hand, in the outer case, the box part 21 and the folding piece 22 are connected freely by bending at the upper end of the side wall corresponding to the hinge part 13 of the inner case. Further, a notch is provided as a push-up hole 23 from the bottom plate to the side wall of the box portion 21.

Further, the length of the side wall of the lid body 12, the length of the connecting upper piece 14, the length of the lower connecting piece 15, and the length of the folded piece 22 are approximately the same, and the length of the occlusal piece 16 is approximately the same as the length of the folded piece 22.
shorter than the length of 2. Before the box of this embodiment is opened, the inner box is placed inside the outer box, as shown in FIG. . When the inner box is pushed up through this push-up hole 23, as shown in FIG. 2, the tip of the folded piece 22 comes into contact with the continuous portion of the connecting lower piece 15 and the interlocking piece 16. When pushed up further, the lid body 1 is removed by the connecting upper piece 14.
2 is pulled and rotates about the hinge part 13, and the lid 12 opens to the state shown in FIG. 3, and the contents can be taken out. Up to this point, all you have to do is push up the inner box using the push-up hole 23 and it will be automatic.

Naturally, the present invention is not limited to the above-mentioned embodiment, and the mutual relationship of the connectable piece 15, the interlocking piece 16, and the foldable piece 22 only changes the position at which the lid body 21 rotates. Consider other examples,
In addition, the push-up hole 23 is not limited to the above-mentioned location, but the position, shape, and size do not matter as long as it is provided so that the inner box can be pushed up.
Furthermore, it goes without saying that the position, shape, and size of the box, such as the position of the hinge, do not require modifications such as a double bottom that are not related to the gist of the present invention.

It goes without saying that the present invention can be modified in various ways without departing from the gist of the invention.

(Effect of the invention) With the invention, it has become possible to easily take out the contents.
