Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention mainly relates to a confectionery such as a candy and a packing container thereof, or a packaging container suitable for packaging a toy or the like.

[Problems to be Solved by Conventional Techniques] Conventionally, there are various forms of packaging containers for confectionery such as candy and toys, and recently, containers made of synthetic resin, particularly for heat insulation effect and cushioning effect, have been developed. The use of containers made of synthetic resin foam such as certain polystyrene resin foam is also increasing.

In particular, since many confectioneries and toys are intended for children and the like, it is desirable that the packaging container for them be one that draws the attention of children and the like. As one of them, there is one in which a container and a lid are formed in a divided shape of a hollow body having an approximately oval shape or a spherical shape.

However, if the divided ends of the container and the lid are in the form of a straight line in the circumferential direction, the design effect and interest when the lid is opened and displayed is lacking, and it is not so noticeable. .

There is also an oval-shaped container in which the divided shape and the divided ends of the container and the lid are made into concave and convex shapes corresponding to each other, but the abutting surface of the divided end is at a right angle to the outer surface. Since it is only a surface, the lid body is relatively easy to come off, and other auxiliary stopping means such as an adhesive tape is required in the packaged state.

The invention of the present application is made in view of the above, and is composed of a container and a lid that form a substantially oval-shaped divided shape, and in particular, the divided end is made into a concavo-convex shape that is elaborate in relation to the shape of the container. It is intended to provide a packaging container which is easy to draw attention and has good stability in a butt-fitted state of a container and a lid.

[Means for Solving the Problems] A packaging container according to the present invention for solving the above problems comprises a container and a lid which are molded from a synthetic resin foam and are formed into a split shape of a hollow body having a substantially oval shape. , The dividing end of the container and the lid,
Each of the triangular peaks and the valleys between the triangular peaks is formed in a corresponding shape, and the divided ends of the concave and convex shapes are provided so that they can be butt-fitted to each other. It is characterized in that it is twisted so as to cut inward from the top to the valley side.

[Operation] According to the packaging container of the present invention having the above-mentioned configuration, when the container and the lid, which have a substantially oval-shaped divided shape, and the lid are separated from each other, the divided ends have an uneven shape, particularly a triangular shape. A concave and convex shape is formed by the part and the valley, which, in combination with the outer shape of the substantially oval shape, gives the appearance of an egg naturally cracking. In addition, the protrusion of the uneven mountain portion increases the inner volume of the container as compared with the case of being divided and formed in a straight line in the circumferential direction.

When the lid body is fitted to the container so that the divided ends of the concave and convex shapes are butted against each other, the concave and convex shapes of both divided ends correspond to each other. Butt fitting is carried out in the valley part between. In particular, the abutting surfaces on both sides of the mountain portion are twisted so as to cut inward from the top of the mountain portion toward the valley side, and the material may be elastically butted and fitted with a synthetic resin foam. As a result, friction is generated in the butt-fitting portion, the lifting of the mountain portion to the outer surface side is suppressed, and a good butt-fitting state is maintained.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.

In the figure, (A) shows a packaging container according to the present invention molded from a synthetic resin foam such as polystyrene resin foam,
As shown in the drawing, it comprises a container (10) and a lid (20) which are formed in a divided shape of a hollow body having a circular cross section and a vertically elongated, substantially oval shape.

As shown in the figure, the divided end portion (11) of the container (10) has a notch (12) that is a divided end portion of the outer half portion by cutting out the outer half portion so as to leave a substantially thick inner half portion. The edge of the triangle is a mountain (1
3) and V-shaped troughs (14) between them are alternately formed. Remaining part of the inner half of the split end (11) (1
Semicircular recesses (16) are formed on the edge of (5) at required intervals in the circumferential direction.

On the other hand, the divided end portion (21) of the lid body (20) has a protruding edge (22) formed in the thick outer half portion corresponding to the notch (12), and the divided end portion of the outer half portion. The end edge of the protruding edge (22) is the uneven shape corresponding to the uneven shape on the side of the container (10), that is, the triangular mountain portion (23) corresponding to the valley portion (14), and the mountain portion between them. It is formed in an uneven shape with the valley (24) corresponding to (13), and in the state where this protruding edge (22) is fitted in the notch (12), both peaks (13) and (23) The troughs (24) and (14) can be butted against each other.

The inner half of the opening end (21) is formed in the step (25) so as to abut the edge of the remaining part (15) of the inner half on the side of the container (10). Semicircular protrusions (26) that fit into the recesses (16) are provided at required intervals in the circumferential direction of the step (25).

Mountains (13), (23) and valleys (1) of the container (10) and the lid (20).
Regarding 4) and (24), it is possible to form them all at the same height and depth at equal intervals, but in the case of the illustrated example, regarding the unevenness of the notch (12) of the container (10) , Open end
(11) is equally divided in the circumferential direction (for example, into 5 equal parts), and the depth of the valley portion (14) is gradually increased in three steps at each equal angle to obtain three kinds of mountain portions (13). Valleys (14) are formed respectively, while the lids (2
Regarding the unevenness of the protruding edge (22) of (0), the protruding height of the peak portion (23) is formed by sequentially increasing it in three steps so as to correspond to the valley portion (14) at the same equal angle as described above. ing.

Particularly, the mountain portions (13), (2) in the container (10) and the lid (20) are
The abutting surfaces (13a) (23a) on both sides of 3) are twisted so as to be slightly inwardly cut toward the valley side from the tops (13b) (23b) as shown in FIGS. 2 and 3. It has a corresponding shape in the state.

On the outer surface of the center of the bottom or the center of the top of the container (10) and the lid (20), there are recesses (17) and (27) that are slightly recessed, and these recesses (17) and (27) At this location, the container (10) and the lid (20), which are in the form of an oval-shaped division, can be stably placed. The same applies if a simple horizontal plane is provided instead of the recesses (17) and (27).

As the synthetic resin foam which is the constituent material of the container (A), a styrene resin foam such as a polystyrene resin and a copolymer mainly composed of styrene, a polyolefin resin foam, a polyvinyl chloride resin foam and others. The synthetic resin foam can be used, and among them, those made of a styrene resin bead foam molding are preferable. Further, a non-foamed or high-density reinforcing skin layer can be provided on the surface of these foams.

The packaging container (A) is used, for example, for confectionery such as candy and assortment thereof, or for packaging toys and the like. The outer shape of the body is roughly oval, and the body is divided.
When the (10) and the lid (20) are separated, the uneven shape of the divided end, especially the uneven shape due to the triangular peaks (13) (23) and valleys (14) (24) appears. Because of this, when combined with the roughly oval outer shape, it has a strange appearance as if the egg naturally cracked, and is easily noticeable. In particular, as shown in the figure, in the case of a combination of three-step peaks (13) (23) and troughs (14) (24), it will be more novel and noticeable. Also, the uneven mountain portion (1
Due to the protrusion of 7), the internal volume of the container (10) is also larger than that in the case where the container (10) is divided and formed in a straight line in the normal circumferential direction, so that a large number of objects to be packaged can be stored.

Then, the projecting edge (22) of the divided end (21) of the lid (20) is put into the container (10).
While fitting in the notch (12) on the outside of the split end (11) of (1) and making the concavo-convex shapes that correspond to each other abut, the crests (13) (23) between the other crests The valleys (24) (14) are elastically butt-fitted by the elasticity of the foam. Especially, at this time, the abutment surfaces (13a) (23) on both sides of the crests (13) (23) that are twisted so as to cut inward from the tops (13b) (23b) toward the valley side.
(a) As a result of elastically butting each other, friction occurs at this butt-fitting portion, and lifting of the peaks (13) (23) to the outer surface near the tops (13b) (23b) is suppressed. Therefore, a good fitting state is maintained.

In the above embodiment, the notch (12) is provided outside the divided end of the container (10), and the lid (20) is provided with the protruding edge (22) that fits into the notch (12). Although the case of carrying out the present invention has been shown, it is also possible to carry out the present invention by forming both the divided end portions into a concavo-convex shape with corresponding peaks and valleys without providing these notches and protruding edges. Further, the container and the lid of the illustrated embodiment may be reversed.

[Advantages of the Invention] As described above, according to the present invention, the container is composed of a container and a lid which are divided into a substantially oval shape, and in particular, the divided end is combined with a substantially oval container shape, It has a unique appearance as if the eggs were naturally broken, and stores sweets and toys.
When the cover is opened and displayed, it is particularly easy for the purchaser such as a child to pay attention, which can contribute to sales promotion. Further, the protrusion of the mountain portion of the divided end portion allows a large amount of the above-mentioned packaging object to be stored.

Moreover, in the butt-fitting state of the other ends of the concave and convex shapes formed by the triangular peaks and troughs, the fitted state, that is, the packaged state can be favorably maintained due to the twisting of the butt surfaces on both sides of the ridge.

Further, since the container is made of a synthetic resin foam, it is lightweight and easy to handle, and also has buffering properties and heat insulating properties, so that it is possible to satisfactorily protect objects to be packaged such as confectionery, and, as described above, the divided ends are Even an uneven shape can be easily produced and provided by molding.
