Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a container whose lid can be opened and closed by a one-touch operation, and more particularly to a lid piece attached so as to face a container opening. When the tip portion is closed, the tip portion is formed so as to overlap with each other to close the opening portion of the container, and the fold line formed between the lid piece and the side surface is curved downward so that the tip portion is rigid. In order to maintain the polymerization state, it is possible to easily handle when opening and closing the container.

[Prior Art and its Problems] Conventionally, there is known a structure in which a container is opened with one touch by pressing a part of the container (see, for example, Japanese Utility Model Publication No. 48-38042).

The above-mentioned conventional container is a container having a substantially quadrangular opening surface, and two triangular lid plates are attached to the opening surface, and the entire long sides of both lid plates overlap each other in the diagonal direction on the opening surface. The long sides of the lid plate are overhanging, the both long side portions have locking points, and the corresponding concave and convex portions are provided, and the two lid plates form a curved surface that bulges upward. As described above, the structure is engaged at the locking point.

In the case of the structure described above, a lid plate that engages in a diagonal direction is attached to the opening surface of a rectangular container, and when pressing force is applied to the corners of the lid plate in the long side direction, the lid opens and the pressing force is reduced. The lid automatically closes when released. Therefore, the above-mentioned one has a problem that when one sheet material is cut and assembled, the paper removal becomes complicated and the material cost is increased, and at the time of use, due to the restriction on the lid plate attachment, the lid of the container is closed. Since the plate cannot be opened greatly, and the lid plate automatically opens when the hand is released, there is inconvenience in handling when storing and taking out the contents.

The object of the present invention is to solve the above-mentioned drawbacks of the conventional type, and to obtain a container of good paper picking, which is obtained by punching a single rectangular sheet and engraving ruled lines on it. After assembly, the lid can be opened and closed with one-touch operation, and when the lid is closed, the rigidity of the lid itself can maintain the overlapped state of the lids, and when the lid is opened, the opening surface can be opened. The purpose of the present invention is to obtain a container with a large opening for easy storage and removal of contents.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention is a container having a square opening on the upper surface thereof, and a pair of left and right sides is formed on the upper side surface of the container via a fold line. Of the folding lid having a fold portion and an upper surface lid not having a fold portion, and the folding lid and the upper surface lid are integrally connected to each other in the circumferential direction of the opening via the fold portion, A fold line formed between the top lid and the side surface of the container is formed to have at least a downward convex arc shape, and a tongue piece is formed to project at an end edge of the top lid to close the container when the tongue piece is closed. One of the two is pushed into a bag portion formed between the fold portion and the top lid to fix the top lid.

[Embodiment] The present invention will be specifically described below with reference to the illustrated embodiment.

FIG. 1 is a development view of a rectangular cylindrical container according to an embodiment of the present invention, in which a sheet material such as paperboard is cut to obtain a development figure as shown. Reference numerals 1 to 4 are side plates continuously provided in one direction, and 5 is a joining piece provided at an edge of the side plate 4. Reference numerals 6 to 9 are lid pieces continuously provided on the upper sides of the side plates 1 to 4 via folding lines.
This lid piece is composed of triangular folding lids 6 and 8 that are continuously provided on the upper sides of the side plates 1 and 3, and chamfered top lids 7 and 9 that are continuously provided on the upper sides of the side plates 2 and 4. Reference numerals 6 and 8 are provided with a pair of triangular folds 11, 11 or 12, 12 on the left and right sides thereof, while the top lids 7, 9 are formed with semi-circular tongue pieces 13 or 14 at their edges. .

As mentioned above, a folding lid having a pair of folds on the left and right,
The upper surface lid having no fold portion is attached every other one, and the folding lid and the upper surface lid are integrally connected in the circumferential direction of the opening through the fold portion. The folding lines 15 to 18 between the four side plates 1 to 4 and the four lid pieces 6 to 9 are each formed in a downward convex arc shape. However, the fold line between the folding lids 6 and 8 and the side plates 1 and 3 does not necessarily have to be formed in a convex arc shape and may be a straight line, or may be a straight line, or between the top lids 7 and 9 and the side plates 2 and 4. Only the fold line may be formed so as to have a downward convex arc shape.

In FIG. 6, reference numerals 19 and 21 are bottom plates connected to the lower sides of the side plates 1 and 3, and 20 and 22 are bottom plates connected to the lower sides of the side plates 2 and 4. The bottom plate is a 45-degree fold line. Engraved 23, 24, both bottom plates
19 and 22 and 20 and 21 are pasted together at the glued portion G shown in the figure to form a so-called one-touch bottom. Needless to say, this one-touch bottom is not an essential requirement of the container of the present invention, and various changes can be made, for example, by adopting a lock bottom structure.

When assembling this container, glue is applied to the glued part G on the bottom plate so that the adjacent bottom plates 19 and 22 and 20 are joined together.
And 21 are fixed to form a one-touch bottom, and the joining piece 5 and the end edge of the side plate 1 are fixed to connect the side plate group in a rectangular tube shape. In this case, since the container bottom plate of the illustrated embodiment has a one-touch bottom (see FIG. 5), it can be folded after the box is made, and can be stored in a flat shape when not in use.

In the container of the present invention, as shown in FIG. 1, when the lid of the container is opened, the opening surface is large and the contents can be stored and taken out easily. On the other hand, when closing the above-mentioned opening surface, a pair of triangular folds 11 and 11 are provided on the left and right sides of the triangular folding lids 6 and 8 which are continuously provided on the upper sides of the side plates 1 and 3.
Or, it is turned inward through 12 and 12, and the folds are folded between the top lid and the folding lid (Fig. 2). After that, the tongue pieces 13 and 14 projectingly formed on the end edges of the upper lids 7 and 9 are overlapped with each other when the container is closed, and one of the tongue pieces (the tongue piece 14 in the illustrated example) is attached to the fold portion. And the upper cover is pushed into the bag portion 25 formed between the upper cover and the upper cover to hold and fix the upper cover (see FIGS. 3 and 4).

In this case, the convex arcuate fold lines 20 and 22 formed between the top lids 7 and 9 and the side plates 2 and 4 give the top lid a warp and rigidity, thereby providing the tongue of the top lid. Piece 13, 14
Keeps the superposed state, and the tongue piece 14 is locked in the bag portion 25 formed between the folds 11 and 12 and the top lids 7 and 9 to fix the top lid. It becomes a blocked state.

Therefore, confectionery, clothing, etc. can be stored and sealed in this container. On the other hand, when the product in the container is taken out, the upper surface lid 7 on the upper side is resisted against the rigidity given to it. When it is folded back upward, the mouth on the top surface of the container opens relatively easily, and the contents can be taken out by opening the lid largely as shown in FIG.

[Effects of the Invention] As described above, the container of the present invention is a container having a square opening on the upper surface, and is provided on the upper side surface of the container through a fold line,
The folding lid having a pair of folds on the left and right and the top lid not having folds are attached every other pair, and the folding lid and the top lid are integrally connected in the circumferential direction of the opening via the folds. At the same time, the fold line formed between the top lid and the side surface of the container is formed so as to form at least a downward convex arc, and a tongue piece is formed to project at the edge of the top lid to close the container. , One of the tongue pieces is pushed into a bag portion formed between the fold portion and the top lid, and the convex arc-shaped fold lines 20 and 22 engraved between the top lid and the side plate are thereby applied to the top lid. The tongue piece of the upper lid maintains the overlapped state by giving rigidity together with the warp, and the tongue piece 14 is provided in the bag portion 21 formed between the fold portion and the upper lid.
Is locked to fix the top lid. Therefore, the present invention can provide a container with good paper removal by simply punching out one rectangular sheet and engraving ruled lines on it. After assembling, the lid can be opened and closed by one-touch operation. When the lid is closed, it is possible to maintain the overlapping state of the overlapping lids due to the rigidity of the lid itself, and when the lid is opened, the opening surface is large so that the contents can be stored and taken out easily. There is also an effect that it can be formed.
