[0004]

[Problems to be solved by the device]

  However, in both cases of FIG. 5 and FIG. 6, said flange edge (53) The part of (63) is projected outside the container, so the container falls down The flange edge (53) (63) when it comes into contact with other objects Easily hits the floor or other objects, and when this part collides with the floor, the impact force is It will be directly transmitted to the open end of the storage unit, and local external pressure will be applied to the packaged items inside. There was a risk that the force would act and damage the packaged article.

[0005]   Particularly, as a result of the drop test, the flange edges (53) and (63) collide with the floor surface. Not only in the case of carrying out, but of the storage parts (52) (62) of the upper and lower body parts (51) (61) Even if a corner collides with the floor, the impact is localized and damages the packaged items inside. There was a risk of injury.

[0006]   In addition, if there is a protruding portion due to the flange edge as described above, this container can be stepped. It is not stable when stored in an outer package such as a cardboard box and packed, and it cannot be inserted into a tubular case. Not suitable for simple packaging.

[0007]   The present invention has been made in view of the above, and is a mere flange-like partially protruding portion. To prevent local impact when dropping or contacting other objects, and A packaging container that can effectively absorb and mitigate the impact and that can protect the packaged goods satisfactorily. Is to provide.

[0008]

[Means for Solving the Problems]

  The packaging container of the present invention that solves the above problems is formed from a synthetic resin sheet, and Each of them is butt-joined to each other through the open ends of the accommodating portions provided so as to face each other. It consists of upper and lower body parts with extended flange edges, and the outside of the flange edges of the upper and lower body parts. Skirt-shaped so as to surround the storage portion with a space around each storage portion from the peripheral edge. It is characterized in that the outer plate of is bent and extended.

[0009]   Convex parts that bulge inward or outward on the top and bottom surfaces of the storage parts of the upper and lower parts And a skirt-shaped outer plate is provided with a height of the storage portion including the convex portion. Those formed to have substantially the same length or a slightly shorter length are particularly preferable.

[0010]

[Action]

  According to the present invention having the above structure, the flange edges of the upper and lower body parts are butt-joined to each other. In the packaged state, the skirt-shaped outer plate bent and extended from the flange edge is stored. It exists so as to surround the storage part and does not have a mere outward flange-like protrusion. Yes. Therefore, even if this container tilts and falls, or comes into contact with other objects, The outer surface of the outer plate will hit the floor, etc., and the butt jointed flange edge Minutes and corners of the storage part do not locally collide with the floor surface.

[0011]   In particular, since there is a gap between the outer plate and the inner storage body, Even if the outer plate collides, the impact due to the contact will not be directly transmitted to the storage part. The outer plate itself can also be elastically deformed within the above-mentioned interval range, which causes the above-mentioned collision. It is possible to effectively absorb and mitigate the impact caused by.

【Example】

  Next, an embodiment of the packaging container (A) of the present invention will be described with reference to FIGS.

[0013]   In the figure, (1a) and (1b) are made of synthetic resin foam sheets with a relatively high elasticity. And a container formed into a predetermined shape by a forming means such as a less forming, a vacuum forming, a pressure forming. Both the upper and lower parts which become a lid are shown. This upper and lower body (1a) (1b) is Outward from the open ends of the accommodating portions (2a) and (2b) that are recessed so as to face each other. It has extended flange edges (3a) and (3b). The edges (3a) (3b) are butted and joined to each other.

[0014]   Then, the flange edges (3a) and (3b) are respectively accommodated from their outer peripheral ends. Surrounding the storage parts (3a) and (3b) with a required space around the parts (2a) and (2b). The outer plates (4a) and (4b) extending in a skirt shape are bent and extended. This The outer plates (4a), (4b) of the are usually as shown in the figure because of die cutting during molding. It is formed in a taper shape that slightly expands outward as the drying tip. Therefore, both upper and lower body In the joined state of (1a) and (1b), the flange edges (3a) and (3b) are outer plates. It will be inward.

[0015]   The outer plates (4a), (4b) are the heights of the accommodating parts (2a), (2b) as shown in the figure. It is formed to have a length that is substantially the same as or slightly shorter than the (depth). Exterior of cardboard boxes, etc. When stored in the body, the outer plates (4a), (4b) have elastic action for absorbing shock. In order to make use of it, the length is slightly shorter than the height of the storage parts (2a), (2b). It is good to leave it.

[0016]   In addition, the top surfaces (5a) of the storage parts (2a) and (2b) of the upper and lower body parts (1a) and (1b) are also Or, the bottom surface (5b) may be a simple flat surface, but as shown in the figure, Providing rib-shaped convex portions (6a) and (6b) that bulge on the inside to accommodate stored packaged articles In practice, it is particularly preferable to be able to reduce the impact. In this case, The outer plates (4a), (4b) of the storage unit (2a) including the protrusions (6a), (6b). The length is formed to be substantially the same as or slightly shorter than the total height of (2b).

[0017]   Butt joining of flange edges (3a) and (3b) of upper and lower body (1a) (1b) As a means of joining, as shown in FIG. 3, in addition to the case of joining by means such as adhesion or heat fusion. As shown, one of the flange edges (3a) (3b) is fitted with a recess or notch. A convex portion that forms a dowel hole (7b) and that is fitted into the fitting hole (7b) on the other side (7a) is formed, and both flange edges are joined by the fitting of both. Can also be combined with. The position of the fitting hole (7b) and the convex portion (7a) in this case, The number, interval, etc. can be set arbitrarily. Also, this is used in combination with the above-mentioned means of adhesion or heat fusion. You can also do it.

[0018]   For example, as a synthetic resin sheet that is a constituent material of the upper and lower body parts (1a) and (1b), For example, polystyrene-based resins such as polystyrene and copolymers mainly composed of styrene, Polyethylene such as polyethylene, polypropylene and copolymers mainly composed of olefins For example, foam sheets of olefin resin, polyvinyl chloride resin and other synthetic resins Wear. For lightweight packaging, flexible polyolefin resin foam sheets are preferred. In the case of slightly heavy packaged goods, a slightly hard police A ethylene resin foam sheet is preferred. Also, depending on the type of contents and other needs It is more flexible than the slightly hard and flexible styrene resin foam sheet described above. Use composite or laminated sheet with foamed sheet of olefin resin with You can also In this case, use a flexible polyolefin resin foam sheet inside the container. It is preferable to use it in terms of protection of the packaged article. Moreover, in some cases, Alternatively, a flexible non-foamed synthetic resin sheet may be used.

[0019]   The packaging container (A) having the above-mentioned configuration is placed in a state in which the articles to be packaged are stored in the upper container. By butt-joining the flange edges (3a) and (3b) of the lower both bodies (1a) and (1b) Hold it in a closed state and remove it from cardboard, cardboard, etc., as shown in FIG. 4, for example. It is inserted in the cylindrical case (10). Or normal cardboard with flaps It is packaged by being housed in an exterior body such as a box (not shown). In addition, the entire packaging container (A) It is also possible to wrap with shrink film or wrap film.

[0020]   Then, around the side of the packaging container (A), the upper and lower body parts (1a) and (1b) are opened. Skirt-shaped outer plate (4a) extending from the flange edges (3a) (3b) at the mouth end Since it has (4b) and does not have a simple flange-shaped protruding portion, as shown in FIG. It can be easily inserted into a tubular case or stored in a box and can be packaged with good stability. Again cylinder The appearance of the packaged state when inserted in the case is also improved.

[0021]   Also, in the above packaging state, if the container falls or comes into contact with other objects, Since the outer plates (4a) and (4b) will come into contact with the floor and other objects, The impact can be received on the wide surface of the outer plates (4a), (4b). I.e. The flanges (3a) (3b) and the corners of the storage sections (2a) (2b) are on the floor or other areas. Collision with an object can be prevented by the outer plates (4a), (4b).

[0022]   Moreover, between the outer plates (4a) (4b) and the inner storage parts (2a) (2b). The outer plates (4a) and (4b) collide with the floor and other objects because they have a space (S) in Even if it collides, the impact is not directly transmitted to the storage parts (2a) and (2b), and also outside The plates (4a) (4b) themselves can be elastically deformed within the above-mentioned interval (s), The impact of the above collision can be effectively absorbed and mitigated by the drop test. It can withstand tests well and can protect the inner packaging goods well.

[0023]   Especially, rib-shaped protrusions are formed on the top surface (5a) and the bottom surface (5b) of the storage portions (2a) and (2b). By providing the parts (6a) and (6b), there is a gap between the packaged article inside and the exterior body. In such a case, the impact absorbing effect on the inner packaged article is further excellent.

[0024]

[Effect of device]

  As described above, in the packaging container of the present invention, a mere flange-shaped partial protrusion is used. Since it does not have a protruding part, it can be easily packaged with an exterior body such as a corrugated box, and in the packaged state The stability and appearance of the outer plate is good, especially with a space around the side of the container. By providing the external pressure and shock caused by falling or contact with other objects, It can be received by a board, and its impact can be effectively absorbed and mitigated, which makes it locally Protects the stored packaged items without causing a strong impact on the packaged items inside. I can do it well.
