DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin container used for housing and packing foods such as ready-made side dishes and various pickles having juice.

[0002]

[Prior Art] Ready-made foods such as prepared dishes and lightly pickled foods are packaged in containers made of synthetic resin and sold for sale. Some prepared foods include stewed fish, cut radish, and Koya tofu. And cucumber fir are stored in a synthetic resin container together with a broth or sap, and kimchi,
In the case of pickles such as plums or pickled pickles, they are stored in a synthetic resin container together with the pickled juice.

In these synthetic resin containers for storing foods, a lid is formed by molding a synthetic resin sheet into a dish shape that fits into the upper opening of the container body, and this is fitted to the upper edge of the opening of the container body. By heat-sealing so that it can be removed again,
It is sealed so that juice does not spill during the sales process.

[0004]

However, when the juice of the stored food such as prepared foods and pickles is stored at the bottom of the container, the knob portion provided on a part of the outer periphery of the lid is pinched and the heat fusion surface with the container body is held. The juice may be inadvertently splattered when peeling off and opening the lid, especially when the juice is large such as stewed oden, so to prevent this, only the juice before opening the lid fully to prevent this May be discharged in an appropriate amount. You may also want to cut the broth or pickle before eating.
In order to cut the juice contained in the contained food in this way, a part of the lid is opened by tilting a knob provided on a part of the outer periphery of the lid and peeling off the heat fusion surface of the lid and the container body, and tilting the lid. It will be discharged from the place.

However, since a lid made of a synthetic resin sheet is strong and hard to bend arbitrarily, it is not easy to open only a part of the lid reliably. It was easy for food to leak out together.

[0006] An object of the present invention is to solve such a problem, and it is possible to easily open a juice cut or a cut groove, and to use only the juice without causing the contained food to flow out. It is an object of the present invention to provide a container made of synthetic resin for foods such as prepared foods, which can easily discharge the outside of the container.

[0007]

An object of the present invention is to provide an upwardly open synthetic resin container body having a bottom wall and a side wall rising from the entire periphery of the bottom wall, and an upper end opening of the side wall of the container body. A lid made of a synthetic resin for closing the portion, wherein the container body is provided with a flange projecting outward from the entire periphery of the upper edge of the opening in the side wall of the container, and the lid is re-peeled over the entire periphery of the upper surface of the flange. It is heat-fused as much as possible, and in the circumferential part of the flange, in the circumferential part of the opening upper edge of the side wall,
A juice-cut portion extending from an upper edge lower than an upper edge of the other portion in the circumferential direction to an inner peripheral portion of the flange is formed, and a part of the lid covering above the juice-cut portion is peeled off from the flange. Is provided at a peeling direction start end of a part of the outer peripheral edge of the heat-sealed portion of the lid, and a part of the lid covering above the juice-cutting part is formed from the flange. It is characterized in that it is configured to be peeled off and bent, and that a juice cutout is opened between the bent portion of the lid and the juice cutout portion.

[0008]

According to the above-mentioned synthetic resin container, the lid is heat-sealed and sealed so as to be removable over the entire circumference of the flange of the container body. Can be prevented from spilling out of the container body. When the juice is cut before eating the contained food, the user grips the knob of the lid and folds the part of the lid that covers the upper part of the juice after peeling off the heat-sealed surface with the flange of the container body. Thereby, a slight juice cut can be opened between the bent portion and the juice cut portion. Thereafter, only the juice can be discharged from the juice cut by tilting the whole container body so that the juice cut is downward.

FIG. 7 is a cross-sectional view showing a part of the container in a juice-cut state.

The synthetic resin container for foods such as prepared foods according to the present invention comprises a container body 1 and a lid 2 as shown in FIGS. 1, 4 and 5. As shown in FIG. 5, the container main body 1 is formed by forming a thermoplastic synthetic resin sheet such as polyethylene terephthalate into a square bottom wall 3 by hot plate molding or the like, and extends upward from the entire circumference of the bottom wall 3. The inclined side wall 4 is formed into a substantially square bowl shape having the raised inclined side wall 4, and the flange 6 is formed outwardly in a rectangular shape from the entire periphery of the upper edge 4 a of the opening of the inclined side wall 4. The outer peripheral edge 6a of the flange 6 is formed to be bent downward.

In one corner of the container body 1, adjacent inclined side walls 4, 4 are formed so as to be connected to each other by a chamfered side wall 7 as shown in FIG. The flange 6 to be formed is formed in a substantially triangular shape in plan view as shown in FIG. The juice cutting portion 9 is formed in the triangular portion 61 of the flange 6. That is, as shown in FIGS. 1, 3 and 6, the juice cutting portion 9 is formed on a part (triangular portion 61) of the flange 6 in the circumferential direction.
Upper edge 7 of chamfered side wall 7 lower than upper edge 4a of inclined side wall 4
a is formed so as to extend from a to a part of the inner circumference of the flange 6.

As shown in FIG. 3, in the juice removing section 9,
The upper surface (reference surface) 6b of the flange 6 has at least one (two in the illustrated example) cross section U communicating with the inside of the container body 1.
A U-shaped juice kerf 10 is recessed in the middle of the flange in and out. Therefore, an outer peripheral portion 6c flush with the upper surface 6b remains on the outer periphery of the upper surface 6b of the flange 6 on the outer extension of the outer end 10a of the juice groove 10. The ridges 11 on both sides of the juice groove 10 are flush with the upper surface 6b of the flange 6 or slightly higher than the upper surface 6b. A region 12 between the outer peripheral portion 6c of the upper surface 6b of the flange 6 and the outer end 11a of the peak portion 11 is formed lower than the upper surface 6b. Of course, it goes without saying that the cross-sectional area of the juice kerf 10 is set to a size that does not allow the accommodated food to pass through.

As shown in FIGS. 1 and 4, the lid 2 is made of a thermoplastic synthetic resin sheet such as polyethylene terephthalate by hot plate molding or the like. A main surface wall portion 15 which is formed in a square shape and slightly fits into the upper end opening 8 and which is integrally connected to the outer periphery of the main surface wall portion 15 in a groove shape in cross section and is covered with the flange 6 of the container body 1. It is formed in a shape having a peripheral frame portion 16 to be fitted. The peripheral frame portion 16 having a substantially square shape in plan view and having a groove-shaped cross section is overlapped with the rising wall 16 a which is overlapped on the inner periphery of the upper end opening 8 of the container body 1 and the upper surface of the flange 6 and is thermally fused. The hanging wall portion 1 which is superimposed on the outer surface of the flat wall portion 16b and the downward facing outer peripheral edge 6a of the flange 6
6c.

The juice-cut groove covering portion 17 covering the upper portion of the juice-cut portion 9 of the container body 1 at one corner of the peripheral frame portion 16 having a substantially square shape in plan view is almost the same as the triangular portion 61 of the flange 6. It is formed in a substantially triangular shape in plan view. A knob 18 is formed on the tip end side of the juice groove cover 17 so as to extend outward from a position slightly lower than the upper surface of the juice groove cover 17. A foldable fold 19 is provided on the substantially triangular juice kerf cover 17 in a plan view.
Is formed in a direction substantially perpendicular to the peeling direction P of the lid 2 so as to correspond to a position above the outer side end 10a of the juice cutting groove 10 when the lid 2 is placed on the upper end opening 8 of the container body 1 in a predetermined direction. . The fold 19 of the juice kerf covering portion 17 of the lid 2 is
In the illustrated example, it is configured by press-forming a narrow groove 20 on the upper surface of the juice kerf cover portion 17, but in addition to this, the portion may be formed in a thin-walled shape. It can be so.

In order to package food 21 such as a side dish having juice in a synthetic resin container composed of the container body 1 and the lid 2 having the above structure, as shown in FIG. After the food 21 has been stored, the lid 2
Container body 1 in a predetermined direction so that
The main surface wall portion 15 is slightly fitted into the upper end opening portion 8 and fitted, and the peripheral frame portion 16 is fitted over the flange 6. Thereafter, the flat wall portion 16b of the peripheral frame portion 16 of the lid 2 is heated and pressurized over the entire circumference of the upper surface 6b of the flange 6 by a heating press, whereby the lid 2 is heat-fused to the container body 1 in a releasable manner. At the same time, the container body 1
Of the flange 6 is flush with the upper surface 6b of the flange 6 or slightly higher than the upper surface 6b. A region 1 between the upper surface 6b of the triangular portion 61 of the flange 6 and the outer end 11a of the crest 11, although being thermally fused so as to be peelable.
2, and the outer end 10a of the juice kerf 10 is formed lower than the upper surface 6b of the flange 6, so that the juice kerf cover portion 17 of the lid 2 is in a non-fused state at the corresponding location. Become.

In the synthetic resin container having the above-described structure, the lid 2 is heat-sealed so as to be removable over the entire periphery of the flange 6 of the container body 1 and hermetically sealed. No leakage to Food 21
When the juice is to be cut before eating or before the lid 2 is fully opened, the knob 18 of the lid 2 is pinched, and as shown in FIG. 9 is peeled off in the P direction to a position reaching the fold 19 or an extension of the fold 19. This peeling direction is indicated by a symbol P in FIG. At the time of peeling, the juice kerf covering portion 17 of the lid 2 is in a non-fused state with the outer end 10a of the juice kerf 10 and the region 12 of the container body 1 as described above. The juice kerf cover 17 can be easily peeled off with such a small peeling force.

When the juice kerf cover 17 of the lid 2 is peeled off to a position reaching the fold 19 or an extension of the fold 19, as shown in FIG.
Can be easily bent along the fold line 19 so that the knob 18 is in the upward posture. By this bending, a slightly opened state is obtained in which the upper part of the juice kerf 10 is kept covered with the lid 2 and only the outer side end 10a of the juice kerf 10 is exposed to the outside. .
Therefore, in this slightly opened state, as shown in FIG. 7, when the entire container body 1 is tilted so that the juice-cutting portion 9 faces down, the juice in the container body 1 is discharged from the juice-cut groove 10 to the outside. However, the stored food 21 can be prevented from flowing out of the juice kerf 10.

The present invention is not limited to the case where the container body 1 is formed in a square shape in plan view as in the above embodiment, but is formed in another polygonal shape or in a circular shape in plan view as shown in FIG. The same can be applied to the ones.
However, even when the container body 1 is formed in a circular shape in plan view, as shown in FIG. 9, on the upper surface 6 b of the flange 6 formed to project outward from the upper edge of the opening of the container body 1,
As in the case of the above embodiment, the juice cutting portion 9 and the juice cutting groove 10
And a ridge 11, while the lid 2 has a juice kerf covering 1
Needless to say, a fold 19 is provided and a fold 19 is provided at a predetermined position of the juice groove cover 17.

[0019]

According to the present invention, the juice cut opening can be easily opened by grasping the knob portion of the lid at the time of juice cutting and slightly peeling the lid from the upper surface of the flange and then bending a part of the cover covering the juice cutting portion. This has the effect that juice can be cut out without causing the contained food to flow out of the cutout.
