[Industrial applications]

 TECHNICAL FIELD The present invention relates to a packaging container that is convenient for transporting and storing fish, vegetables, meat, dairy products, and particularly thin perishables such as long onions and asparagus.

[0002]

[Problems to be solved by conventional techniques and devices]

 It is well known that a foam synthetic resin packaging container for transporting perishables, etc., in which a lid box body is configured to be freely fitted by providing a stepped portion at the upper edge of the body box body, In this known packaging container, the fitting edges of the body box and the lid box are fitted horizontally. For this reason, when selling products such as perishables that have been transported in stores as they are, it is difficult to see the stored products unless a table is placed under the box and supported forward. There was a problem that long onions and asparagus were inconvenient to put in and take out.

Therefore, the inventors of the present invention can fit the body box body and the lid box body at an angle so that it is convenient when the fresh food transported using the packaging container is directly placed on the store or the like and sold. I tried to make a prototype container, but when this prototype container is stacked, the lower container will be loaded too much, so the front part (bottom surface) of the mating edges that are not inclined From the above, it was found that the lower fitting edge) was damaged and the lid box body slipped down from the body box body, making it impossible to maintain the stacked state.

The present invention has been made in view of the above points, and its purpose is to enable diagonal fitting of the body box and the lid box, which is convenient for loading and unloading the contained items, and is useful for stacking the items. An object of the present invention is to provide a packaging container that solves the problem of the lid box body falling off.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the packaging container, which is a feature of the present invention, has a body box made of a thermoplastic resin foam and a lid box body which can be freely joined by an opening surface formed on a corresponding inclined surface. The sloping opposite edges of the body box and the lid box can be fitted with each other, and they are formed in a notched shape, and the engaging portions are made to correspond to each other on the opposite edges. It is provided by.

In order to facilitate the opening / closing operation of the lid, the edge part of the body part which is higher than the bottom surface of the body part among the opposite edge parts of the body part which are not inclined, and the edge part It is preferable that the corresponding edge portions on the side of the lid box body are integrally connected by a hinge portion provided with thin-walled strip portions along the both edge portions.

[0007]

【Example】

 Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 3, 1 is a body box, 2 is a lid box that can be fitted into the body box 1, and both are made of thermoplastic resin foam by in-mold bead foam molding. Then, the opening surface portions 11 and 21 of the body box body 1 and the lid box body 2 are formed in the inclined surfaces corresponding to each other, and the body box body 1 and the lid are formed at the edge portions of the opening face portions 11 and 21 which are formed in a discontinuous shape. The box body 2 can be fitted obliquely, and the body box body 1 and the lid box body 2 are connected by a hinge portion 3 as described later.

In the illustrated case, the slanted and opposed edges 12 a and 12 b of the body box 1 and the non-sloped and opposed edges 12 c and 12 d of the body box 1 and the slanted relative of the lid box 2 are shown. The facing edge portions 22a, 22b and the non-tilted opposite edge portions 22c, 22d are formed in the shape of a recess, but the recess does not need to be formed on the entire circumference, and at least the body box. It may be formed on the inclined and opposed edge portions 12a and 12b of the body 1 and on the inclined and opposed edge portions 22a and 22b of the lid box body 2. Further, when more stability is required when stacking layers, it is preferable to provide a notch on the entire circumference.

Of the edges 12c and 12d of the body box 1 that are not inclined and face each other, the edge 12d that is higher than the bottom surface 1a of the body 1 and the lid box that corresponds to this edge 12d The edge portion 22d on the body 2 side is integrally connected by the hinge portion 3. The hinge portion 3 is formed by the central thick-walled strip portion 31 provided along both the edge portions 12d and 22d and the thin-walled strip portions 32 provided on both sides of the thick-walled strip portion 31, while The edges 12d and 22d, which are adjacent to the thin strips 32 and 32, respectively, have surfaces for receiving one side of the thick strips 31 when the body box 1 and the lid box 2 are fitted to each other. The grip portions (escape) 12e and 22e are provided so that the hinge portion 3 can be easily opened and closed.

The inclined edge portions 12a, 12b of the body box body 1 facing each other and the inclined edge portions 22a, 22b of the lid box body 2 facing each other include the edge portions 12a, 12b, 22a, 22d. The locking parts 13 and 23 having different inclination directions are provided in a stepwise manner so as to correspond to each other, and the horizontal joint surface parts 13a and 23a of the locking parts 13 and 23 aim to stabilize the lid at the time of fitting. There is. By providing such locking portions 13 and 23, it is possible to prevent the slip-off during stacking. Therefore, the body box 1 and the lid box body 2 do not necessarily have to be connected by the hinge portion 3, but they are connected by the hinge portion 3 when more stability is required or when it is desired to easily open and close the lid. I like it.

Although the phase cutouts provided in the inclined edge portions 12a, 12b, 22a, 22d may be an inner low step portion or an inner high step portion, the locking portions 13, 23 are provided when the lid is fitted. It is recommended to install it on the inner step to improve the appearance. Further, when the locking portion is provided on the inner step portion, the locking portion is preferably provided on the inner lower step portion in order to prevent the locking portion from being damaged when the product is taken in and out.

Further, instead of the locking portions 13 and 23 having the horizontal joint surface portions 13a and 23a, as shown in FIGS. 4 and 5, modified examples of the locking portion on the side of the body box 1 are shown, respectively. The engaging portions 14 and 15 may be those in which the joint surface portions 14a and 15a are inclined in the direction opposite to the inclination direction of the edge portions 12a and 12b. On the lid box body 2 side, the engaging portions corresponding to the engaging portions 14 and 15 may be provided. A stop is provided.

The inner wall of one of the sets of the body box 1 facing each other (the inner walls on the non-inclined side edges 12c, 12d) is provided with a partition plate-supporting ridge 16 for partitioning the contents. In addition, it is provided. Further, expanded polystyrene, expanded polypropylene, expanded polyethylene or the like is used as the thermoplastic resin foam which is the material of the body box 1 and the lid box 2, and its density is 0.015 to 0.05 g / cm 3. ³ is preferable.

[0014]

[Effect of the device]

 The present invention is as described above, and since the opening surface of the body box is formed as an inclined surface, it is extremely convenient especially for taking in and out of slender contents. At the slanted edge of the box, there is a notch that can fit with each other as well as a locking part, so there is no risk of the lid box falling off when the body box and lid box are mated, and when stacking The inconvenience of excessive load on the lower edge of the body lower than the bottom of the body box is solved, and stability during stacking is further improved. Further, by connecting the body box body and the lid box body by the hinge portion, the opening and closing operation of the lid becomes easy, and the practical value thereof is extremely great in combination with the above points.
