Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multiple container, and more particularly, to a plastic container provided with a plurality of recesses for filling contents.

[0002]

2. Description of the Related Art Conventionally, as a multiple container of this type, a plastic molded container for food packaging has been widely known. For example, it is used as a container for tofu or the like, and after filling the contents, a plastic film for closing is adhesively sealed and packaged on a flange around the concave portion.

[0003]

However, when the liquid is filled into the concave portion together with the contents, such as egg tofu, an extra portion is provided between the plastic film for closing and the flange portion which is a boundary portion between adjacent concave portions. The liquid stays there, causing rot, and the appearance is poor.

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate or reduce the accumulation of liquid or the like at the boundary between adjacent concave portions, and to separate the concave portions from each other at the boundary between adjacent concave portions. It is another object of the present invention to provide a multiple container having sufficient mechanical strength to facilitate the deformation and suppress deformation due to bending between adjacent concave portions.

[0005]

[Means for Solving the Problems]

(2) The multiple container according to the above (1), further comprising reinforcing means for suppressing bending between adjacent concave portions.

(3) The reinforcing means is characterized in that protruding pieces are formed on both sides of the through hole of the boundary portion in a direction substantially perpendicular to the boundary portion (vertical direction in FIG. 2). The multiple container according to the above (2).

(4) The reinforcing means is characterized in that, on both sides of the through-hole of the boundary portion, projecting pieces are formed substantially vertically downward with respect to the boundary portion. It is a multiple container described.

(5) A streak-shaped groove is formed on the inner surface and / or the outer surface of the boundary portion and the protruding piece so that adjacent concave portions can be separated from each other in the groove. A multiple container according to the item (3) or (4).

(6) The multiple container according to the above (5), wherein a cutout portion is formed at a position of a tip of the groove on the projecting piece.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a multiple container showing an example of an embodiment of the present invention, FIG. 2 is a side view of the multiple container shown in FIG. 1, and FIG.

The illustrated multiple container 1 is a plastic container in which a plurality of concave portions 2 and 2 for filling contents are continuously provided at a flange portion 3 thereof, and a flange serving as a boundary between the adjacent concave portions 2 and 2. A through hole 5 is formed in the portion 3.

That is, in the illustrated example, the multiple container 1 is
It has a plurality (two in this example) of recesses 2, 2 formed in a square cup shape and filled with contents, and a flange portion 3 is formed around the upper end of the recesses 2, 2. The plurality of recesses 2 and 2 are continuously provided in the flange portion 3 to form a boundary portion. The multiple container 1 is usually formed as an integral multiple container having a plurality of recesses 2 and 2 by a known molding means such as injection molding using polypropylene, polystyrene, polyethylene terephthalate, or other plastics.

A band-shaped through hole 5 is formed in the flange portion 3 which is a boundary between the adjacent concave portions 2, 2, and the adjacent concave portions 2, 2 are located at both ends of the through hole 5. It is in a mode of being connected at the flange portion 3 which is formed. By forming the through holes 5, the recesses 2 are easily separated from each other at the flange portion 3 which is a boundary between the adjacent recesses 2 and 2, so that the usability is improved. The one shown is through hole 5
Is one, but the number is not limited to this, and a plurality may be provided. The shape is not particularly limited, but is preferably rectangular or oval.

The reinforcing means for suppressing the bending between the adjacent recesses 2, 2 will be described. The reinforcing means is a mechanical means for forming a through hole 5 at the boundary between the adjacent recesses 2, 2. This has an effect of reducing a decrease in strength, and thereby suppresses bending between the adjacent concave portions 2 and 2. In the illustrated example, the outer edge of the flange portion 3 which is located on both sides of the through hole 5 and forms the connecting portion of the recesses 2 and 2 is substantially perpendicular to the outer edge portion (vertical direction in FIG. 2).
Is formed with a protruding piece 7.

In this type of container, after filling the contents,
In some cases, a plastic film for closing is adhesively sealed on the flange portion and shrink packaging is performed. However, by providing a reinforcing means such as forming a protruding piece 7, adjacent concave portions are formed by heat at the time of shrink packaging. Can be effectively prevented from bending (bending).

The position, shape and number of the protruding pieces 7 are not limited to those shown in the figure, but usually, the flange 3 is provided with a sealing plastic film for bonding and sealing. In order to avoid unnecessary protrusion toward the outside of the flange, a flange portion 3 serving as a boundary between adjacent recesses 2 and 2 is formed.
It is preferable to position the lower surface (downward in a direction substantially perpendicular to the boundary portion) out of the through hole 5 and on both sides of the through hole 5.

A groove 11 having a stripe shape is formed on the inner and outer surfaces at the center of the flange 3 and the projecting piece 7 which are boundaries between the adjacent recesses 2 and 2. The groove 11 is a so-called half-cut line for facilitating the separation of the adjacent recesses 2 and 2 at the flange portion 3 serving as a boundary during use or the like.
Functions as a dividing line. Further, the V-shaped or other appropriately shaped notch 8 is formed at the tip of the groove 11 of the protruding piece 7, so that the adjacent recesses 2 and 2 can be more easily separated.

As a reinforcing means for suppressing the bending between the adjacent concave portions 2 and 2, in addition to providing the above-mentioned projecting piece 7,
For example, a flange portion 3 serving as a boundary between adjacent concave portions 2 and 2
May be adopted so as to be thicker than other portions.

The flat portion 3a formed slightly higher on the upper surface of the flange portion 3 is a surface to which a plastic film for closing is adhered. The plastic film for closing is usually applied as an easy-open lid material using an appropriate material such as a high-density polyethylene film. As the contents to be filled in the container, foods such as egg tofu, pudding, and jelly are particularly suitable, but are not limited thereto. It can also be used effectively as a packaging container for retort foods.

The embodiment of the present invention has been described above.
The present invention is not limited to the above-described ones. For example, the present invention is not limited to the above-described two-container container, but also applies to three or more concavities, and also to a multi-container having a plurality of rows and columns. Needless to say, the present invention can be carried out by appropriately changing, adding, etc. within the scope of the present invention.

[0022]

As described above, according to the multiple container according to the present invention, it is possible to eliminate or reduce the accumulation of liquid or the like at the boundary between the adjacent concave portions.
The concave portions are easily separated from each other at the boundary between the adjacent concave portions, and the usability is good. Further, as a multiple container having sufficient mechanical strength capable of suppressing deformation or the like due to bending between adjacent concave portions, the effect is extremely large.
