Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sealed container made of plastic that can be filled with food and that is sealed not only between the body and the lid but also in the partition.
[0002]
[Prior art]
Plastic sealed containers are frequently used for the sale of processed foods and are commonly used for the preservation of cooked foods at home. From such a use, it is made a sealed structure as much as possible for the leakage of food juice and quality maintenance, but conventionally, there has not been provided a container that partitions the inside and can be reliably sealed so that there is no liquid leakage even in the partition. It was.
[0003]
As for the sealed structure, basically, the body and the lid are coupled by elastic coupling between the ridge and the groove. Furthermore, the form used for sale may be provided with a lid-opening prevention device that keeps the locked state until it is opened by the consumer so that the lid cannot be illegally opened midway. Examples thereof include those proposed in Japanese Patent Application No. 7-113958 (Japanese Patent Laid-Open No. 7-113958) related to the applicant.
[0004]
[Problems to be solved by the invention]
As for the sealing structure of the body and the lid, when the protrusion and the groove are elastically coupled as described above, the body is generally made rigid and the lid is made soft or semi-rigid. In the case of a rectangular container, since it is easily deformed flexibly in the middle of its long side, the protrusion and the groove cannot be fitted properly. In particular, when the body is made soft or semi-rigid as means for providing a lid-opening prevention device, the peripheral wall is deformed flexibly, and inconvenience is likely to occur in the operation of closely fitting the lid.
[0005]
As for the sealed structure for partitioning the body, the juice overflows from between the lid and the other just by forming a partition wall inside. Since it is necessary to prevent this, it is considered that a groove should be provided on the lower surface of the lid so as to fit closely to the upper end of the partition wall. However, since a part to be tightly fitted is generated in the partition wall in addition to the surroundings, there is a problem that the opening / closing of the lid, particularly the operation of tightening the lid, is not easy.
[0006]
In view of the above situation, in the present invention, in the connection between the body and the lid, it is possible to easily perform the close fitting operation between the protrusion and the groove in any of the periphery and the partition. An object of the present invention is to provide a hermetic partition container in which juice leakage does not occur.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention comprises a body having a standing wall at the upper peripheral edge, a peripheral coating groove so as to closely fit to the entire upper edge of the standing wall, and an annular shape. This is a plastic container consisting of a concave lid with a wide recessed part formed on the slope wall of the wall, and a partition wall that divides the space is provided inside the body and joined to the lower surface of the concave lid In addition, a slope is formed at both ends and the partition wall is formed low between the two sides, a partitioning groove is provided on the lower surface of the lid to fit closely to the upper end of the partition wall, and an inner peripheral ridge is provided on the inner side of the hanging peripheral wall. The peripheral wall is formed as a peripheral groove that fits closely to the upper end of the standing wall of the body , and the partition wall of the body is formed to receive the inner peripheral ridge of the lid at a high place at both ends. The present invention provides a hermetic partition container characterized by having
[0008]
[Action]
Since the hermetic partition container is configured as described above, the peripheral edge covering groove and the partition attaching groove of the lid are tightly fitted to the standing mouth wall and the partition wall as protrusions on the body side, respectively. In the body, the standing wall and partition wall intersect and reinforce each other, and in the lid, the peripheral groove and partition groove similarly reinforce each other. The lid can be securely tightened, and each tight fit is stably held so as not to leak the juice. In addition, when the lid is put on, the sloped portion of the partitioning groove under the sloped wall first fits into the staged sloped part of the partitioning wall, which serves as a guide and the fit is spread over the whole. Therefore, the close fitting operation in the partition wall is also easy.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, the planar shape of the hermetic partition container P is not particularly limited, and other than polygons such as a regular square and a rectangle, a circle, an ellipse, and the like can be cited as suitable. When the partition wall 3 is provided in the width direction in the elliptical shape, the reinforcing effect is great. However, the partition wall 3 is not limited to a straight shape, but may be a cross shape, a T shape, or the like. The presence or absence of the lid opening prevention device R does not matter. Therefore, it can also be implemented in a container used for storing food in a refrigerator for home use only.
[0010]
Further, the body 1 and the lid 2 are not limited in terms of the hardness material of the plastic, but if the body 1 requiring strength stability is made soft or semi-rigid (in the case of claim 2), this case is particularly effective. Is big. In the case of the same paragraph, with the lid opening prevention device R, this structure is locked so that it cannot be opened by the hanging peripheral wall 21 of the lid 2 being coupled to the band piece 13 integral with the body 1. When the strip 13 is cut off, the locked state is released so that the lid 2 can be freely opened and closed. For this reason, the strip 13 can be easily cut off and the body 1 is soft or semi-rigid. Molded with plastic. In addition, although the knob | pick 17 was provided in order to cut off, and the knob | pick 17 was formed in the shape of the band wound piece 13 in the Example, it may be various so that a downward tongue piece shape may be sufficient.
[0011]
【The invention's effect】
As described above, according to the hermetic partition container of the present invention, food can be divided and packed by the partition wall, but in the connection between the body and the lid, both the surroundings and the partition are reinforced. Since it has a structure, it is possible to easily perform a close fitting operation between the protrusion and the groove, and there is no leakage of juice in both the surroundings and the partition, which is very convenient especially for separately packing the food with the leakage of juice. There is an excellent effect of being. In addition, since the body is softly or semi-rigidly plastic-molded with the lid opening prevention device, the effect becomes remarkable.
[0012]
【Example】
Next, an embodiment of the present invention will be described with reference to the drawings.
[0013]
The drawing shows an example implemented as a container used to pack and sell processed foods. The sealed partition container P has a body 1 made of soft or semi-rigid plastic and a lid 2 made of hard plastic. Molded. The body 1 and the lid 2 are provided with a lid opening prevention device R until the opening, in association with the close fitting structure of the periphery, and the body 1 is provided with a partition wall 3, and the lid 2 is attached thereto. It has a tightly fitting structure.
[0014]
As for the close-fitting structure with the lid opening preventing device R, the body 1 has an upright wall 7 formed at the upper end, a protrusion 9 is provided at the lower end, and a band is formed on the protrusion 9 via a cut line connecting portion 11. A belt-shaped strip 13 is formed, and the strip 13 is placed in parallel with the upright wall 7 at an interval. Further, in the corner portion, the strip 13 is provided with a thin portion 15 by a notch on the inner surface in order to cut it (FIG. 5), and the knob 17 is adjacent to the thin portion 15 counterclockwise in the clockwise direction. Protrusively, the knob 17 is hung by the point connection 19 on the band piece 13. Therefore, when removing the strip 13, first, the knob 17 is pulled apart to disconnect the point connection 19, and then the strip 13 is cut by the thin portion 15 and then cut along the line connection portion 11.
[0015]
As described above, the upper end portion of the body 1 is in the form of a deep groove due to the band strip 13 being juxtaposed to the upright wall 7 via the protrusion 9 and the wire connecting portion 11, so A hanging peripheral wall 21 that fits into the deep groove and an inner peripheral ridge 23 that is joined to the inside of the upright wall 7 are suspended, and the peripheral coating groove is between the hanging peripheral wall 21 and the inner peripheral ridge 23. 24. In addition, the lid opening prevention device R functions as the hanging peripheral wall 21 is coupled to the band piece 13 in a lock shape.
[0016]
As for the lock-like connection of the hanging peripheral wall 21, the belt-wound piece 13 is provided with latching grooves 25 and 26 in two upper and lower stages (FIG. 3), and the hanging peripheral wall 21 is closely fitted in the latching grooves 25 and 26. Engagement ridges 27 and 28 are formed. Therefore, if the band piece 13 is cut off by operating the knob 17 (see FIG. 6), the latch groove 25, 26 as the counterpart with which the engaging protrusions 27, 28 engage is eliminated in the lid 2. As a result of losing the function of the lid opening prevention device R, the lid 2 can be freely opened and closed thereafter. Note that the engaging ridges 27 and 28 are formed low at the corners of the container.
[0017]
Further, the body 1 is formed so as to be low in height by providing paragraph slopes 35, 35 at both ends of the partition wall 3 in accordance with the concave lid, and the inner peripheral ridge 23 of the lid 2 is formed at a high portion at both ends. To receive. Further, a thread bottom 36 that is received by the drop recess 33 of the lid 2 is formed at the lower end.
[0018]
Moreover, about the concave shape of the lid | cover 2, it forms the slope wall 31 in the annular | circular shape in the position close | similar to the circumference | surroundings edge, and has the recessed part 33 which falls widely in the inside. Therefore, a partition receiving groove 37 is formed on the lower surface so as to fit into the entire length of the partition wall 3 in accordance with the recessed portion 33. Therefore, when closing the lid 2, first, the inclined portions 38, 38 of the partitioning groove 37 are fitted into the paragraph slopes 35, 35 of the partition wall 3 (see the two-dot chain line in FIG. 3). It becomes a leading guide that fits.
