Description

Detailed Description of the Invention 3. Detailed Description of the Invention The present invention relates to a packaging box that can safely protect stored items.

Traditionally, fragile items such as hot water cups, plates, vases, vases, sake bottles, and other ceramics are packaged in wooden or paper boxes filled with appropriate cushioning material, but at department stores and other retailers, A large space was required to store packaging materials for various products. Further, depending on the direction in which the impact force is applied, it may not be possible to provide a sufficient cushioning effect, and the product may be destroyed.

In view of such circumstances, the present invention relates to a packaging box in which the side walls forming the container are extendably bent, and the bent portions protrude inward to come into contact with the stored items.
To obtain a packaging box that does not take up a lot of storage space, can store items of various sizes, and has high impact resistance.

This will be explained below along with examples.

In the figure, the container (1) has a bottom body (2) below,
It has a lid (3) on the upper side. Although the container is made in the shape of a regular square cylinder, it can also be formed in other suitable shapes such as a rectangular cylinder, a hexagonal cylinder, a cylinder, or any other suitable shape. The side wall of the container is bent to be expandable and contractible, and a portion of the bent portion protrudes inward so as to come into contact with the stored item (4). Although the container may be made of plastic material with bent side walls, it is shown made of paper material in the figure. When the bent portion is made of plastic material, it may be provided in an annular shape or in a spiral shape so that the bent portions at the same height of the side wall continuously protrude inward or outward. . When making a rectangular tube shape from paper material etc., the bent part (a) protrudes inward and the bent part (b) protrudes outward.
) are formed so that they appear alternately each time the side surface changes at the same height of the side wall. That is, among the folded parts of the side wall at the same height, the folded part (b) located on the other side adjacent to the inner folded part (a) that contacts the stored item is It is recessed and protrudes outward so as not to come into contact with the surface (see Figure 4). At the corner of the container, the inwardly protruding bent part (al) of the - side is connected to the outwardly protruding bent part (b) of the other side. A continuous fold line (5) appears.

Figure 6 shows a developed view of the container, and the base material (6) is made of paper materials such as paperboard and cardboard, but it can also be made of reinforced paper, non-woven fabric, synthetic resin sheet, thin metal plate material, etc. You can also
Continuous vertical folds bent in a V-shape (5), (5)
, (5), (side plate (7) which becomes the side wall of the container by 5-inches,
(3), (9) αq and a connecting plate αυ are defined, and the side edges of the outer side plate αq and the connecting plate η are bent along the fold. The width of the side plate and the degree of curvature of the bent folds are such that when the stored items are stored in the container, the bent portions that are bent along the folds and protrude inward, as will be described later. Just enough to make contact with the stored item. A plurality of folds (b) are provided that extend in parallel in the horizontal direction so as to communicate the respective bent portions of the longitudinal folds (5).

The fold (6) has a mountain fold (6) that becomes a fold that protrudes inward.
Al and valley folds (b) forming outwardly protruding folds are arranged alternately, and the valley folds and mountain folds are shifted in position in the vertical direction by the folds that come into contact with each other. It is arranged. Both ends of the longitudinal fold are linear, thereby defining an edge plate side at both ends of the side plate and the connecting plate, and a fold '241, (towards) the outer side of the edge plate. ), a folding plate (4) and an insert plate α force are provided, and a bent cut (G) is provided between the adjacent folding plate and the insert plate,
A tongue is formed on a part of the insertion plate.

Therefore, the vertical folds (5), (5), (5),
(5), fold the horizontal folds (b) at the mountain folds (a) and valley folds (b), respectively, and fold the side plate αQ into the connecting plate (b). If they are overlapped and adhered with an adhesive such as double-sided adhesive tape, an expandable cylindrical container with a bent portion protruding inward will be formed as shown in the figure. The above-mentioned folding plate (G) is folded back, and the insert plate αη is folded over the edge plate @, and is appropriately adhered with an adhesive such as double-sided adhesive tape to reinforce the opening of the container.

The opening of the container is openably and closably closed by a stopper piece (1), Ql) that abuts the upper end of the stored item. The stopper piece is attached to the inner edge of the opposite side plate of the opening of the container by adhering a connecting plate (a) provided at the base, and a retaining piece (c) extending from the connecting plate through the fold line. , and the opening is closed by engaging the insertion grooves (A) and (C) provided in the engaging piece (Figures 7 and g)Q. ) and the lid body (3) can be made in various ways, but in the figure they are made as shown below. In the center of the base plate, a square top board is defined by a fold (to), and around the top board, there are a fold (7), an outer board 02, an inner board, and an insert board through Gυ. C34) are installed in a row, and rising plates (7) and (1
), and a tongue piece 07), G is provided at the side end of one inner plate.
η is provided. Then, it is bent from each of the above folds, the adjacent upright plates are glued together, the tongue piece is inserted and glued to the back side of the other inner plate, and the insert plate is glued to the top plate. Glue the plate ■ to the top of the top plate as appropriate. The edge plate of the above container (
The part (to) can be fitted into the section surrounded by the inner plate divisions of the bottom body and the lid body obtained as described above,
Adhere the bottom body with adhesive as appropriate.

When the container (1) is not in use or stored, it can be retracted as shown in FIG. 3 to save space. In addition, in order to store ceramics such as hot water cups, prepare a container with a bent part protruding inward so that it comes into contact with the outer periphery of the hot water cup, etc., and put the hot water cup through the opening of the container. It is possible to extend the container to almost the same height as a teacup, engage the stopper pieces (2) and Q]) to close the opening, fit the lid (3), and store the container. At this time, if the container is made of paper material as shown in the figure, the container will return to its contracted state and the stopper piece will come into contact with the upper end of the teacup. After that, the whole thing may be tied with a string or stored in an appropriate outer box.◇ Since the present invention is configured as described above, even items of different heights can be stored according to the height. Even if impact forces are applied from various directions, the side walls move to soften the impact transmitted to the stored items, making it suitable for use as packaging boxes for expensive ceramics and other fragile items. ,
Moreover, the appearance is also excellent.
