TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plastic hermetic partition container which is a container capable of partitioning and packing food, and which is hermetically sealed not only between the body and the lid but also in the partition.
[0002]
[Prior art]
Plastic closed containers are frequently used for selling processed foods, and are also commonly used at home for storing cooked foods. From such a use, the structure is sealed as much as possible in order to maintain the juice leakage and the quality of the food. Was.
[0003]
In the closed structure, basically, the connection between the body and the lid is made by elastic connection between the ridge and the groove. Further, a form used for sale may be provided with a lid opening prevention device that keeps a locked state until the consumer opens the lid so as to prevent the lid from being illegally opened halfway. As an example thereof, the one proposed in Japanese Patent Application No. 7-113958 (Japanese Patent Application Laid-Open No. 7-113958) of the present applicant can be mentioned.
[0004]
[Problems to be solved by the invention]
Regarding the closed structure of the body and the lid, when the elastic connection between the ridge and the groove is performed as described above, the body is generally formed to be rigid and the lid is formed to be soft or semi-rigid. On the other hand, in the case of a rectangular container, it is difficult to fit the protrusion and the groove in a good manner because the container is easily deformed in the middle of the long side. In particular, when the body is made to be soft or semi-rigid as a means to be provided with a cover opening prevention device, the peripheral wall is flexibly deformed, so that the operation of fitting the lid tightly is likely to occur.
[0005]
With respect to the closed structure for partitioning the body, the juice overflows from the space between the lid and the other simply by forming the partition wall inside. In order to prevent this, it is considered that a groove should be provided on the lower surface of the lid so as to closely fit the upper end of the partition wall. However, there is a problem that a part to be tightly fitted is additionally formed on the partition wall in addition to the surrounding area, so that it is not easy to open and close the lid, and particularly to close the lid.
[0006]
In view of the above-described circumstances, the present invention can easily perform the tight fitting operation of the protrusion and the groove in any of the periphery and the partition in the connection between the body and the lid, and in any case, An object of the present invention is to provide a closed partition container that does not cause juice leakage.
[0007]
[Means for Solving the Problems]
Means for Solving the Problems In order to achieve the above object, the present invention provides a body having an upright opening wall at an upper peripheral edge, and a peripheral mounting groove provided on the upper end of the upright opening wall so as to be tightly fitted all around, and A plastic container comprising a concave lid having a wide recessed recess formed by a slope wall of the plastic container, wherein a partition wall for dividing the space is provided inside the body and joined to the lower surface of the concave lid. A closed partition container characterized in that a partition wall is formed at a lower portion between both ends with a paragraph inclination, and a partition attachment groove closely fitted to an upper end of the partition wall is provided on a lower surface of the lid. Things.
[0008]
[Action]
Since the hermetic partition container is configured as described above, the peripheral edge mounting groove and the partition mounting groove of the lid are closely fitted to the upright opening portion wall and the partition wall as the body side protrusions, respectively. In the body, the upright opening wall and the partition wall cross each other to reinforce each other, and in the lid, the peripheral mounting groove and the partition mounting groove have a relationship of reinforcing each other similarly, so that the shape stability is obtained. The lid can be securely tightened, and the respective close fits are stably held so as not to leak juice. Moreover, when the lid is put on, the inclined portion of the partition attaching groove below the sloped wall first fits into the section of the partition wall where the paragraph is inclined. Therefore, the close fitting operation on the partition wall is also easy.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
In the present invention, the planar shape of the closed partition container P is not particularly limited, and may be a polygon such as a square, a rectangle, a circle, an ellipse, or the like. In the case of the elliptical shape, the reinforcing effect is large when the partition wall 3 is provided in the width direction. 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 preventing device R does not matter. Therefore, it can also be implemented in containers used simply for storing food in a refrigerator for home use.
[0010]
The body 1 and the lid 2 are not limited with respect to the hardness of the plastic, but if the body 1 requiring strength stability is made soft or semi-rigid (in the case of claim 2), it is particularly effective at this time. Is big. In the case of the above paragraph, the apparatus is provided with a lid preventing device R, and since the hanging peripheral wall 21 of the lid 2 is connected to the band-wrapping piece 13 integral with the body 1 in this structure, it is locked so as not to be opened. When the strip 13 is cut, the locked state is released, so that the lid 2 can be freely opened and closed thereafter. Therefore, the strip 1 can be easily cut and the body 1 can be soft or semi-hard. Molded with plastic. It should be noted that a knob 17 is provided in order to cut off the shredder, and the knob 17 is formed in a prone shape on the strip 13 in the embodiment. However, the knob 17 may have various shapes such as a downward tongue.
[0011]
【The invention's effect】
As described above, according to the closed partition container of the present invention, the food can be divided and packed by the partition wall, but in the connection between the body and the lid, both the periphery and the partition are reinforced. Because of the structure, it is possible to easily perform the close fitting operation of the protrusion and the groove, and there is no juice leakage in both the surroundings and the partition, which is very convenient especially for separating and packing food with juice leakage. Is an excellent effect. The effect is remarkable when the body is made of a soft or semi-rigid plastic molded body with a lid opening prevention device.
[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 for packing and selling processed foods. The closed partition container P has a body 1 made of a soft or semi-rigid plastic and a lid 2 made of a hard plastic. Molded. The body 1 and the lid 2 have a close-fitting structure around the perimeter, so that an opening prevention device R up to opening is configured, and a partition wall 3 is provided on the body 1, and the lid 2 is attached to the body 1. It has a close fitting structure.
[0014]
With respect to the close-fitting structure with the lid preventing device R, the body 1 has an upright opening wall 7 formed at the upper end thereof, a protruding ridge 9 protruding from the lower end thereof, and a band The band-shaped strip 13 is formed, and the band-shaped strip 13 is placed in parallel with the upright opening wall 7 at an interval. In addition, a thin portion 15 is provided in the corner portion by cutting out the inner surface of the band wound piece 13 to cut it (FIG. 5), and the knob 17 is rotated clockwise adjacent to the thin portion 15 in a counterclockwise direction. The tab 17 is protruded, and the knob 17 is turned down on the strip 13 by the point connection 19. Therefore, when removing the strip 13, first, the knob 17 is separated to disconnect the point connection 19, then the strip 13 is cut at the thin portion 15, and then cut along the wire connection 11.
[0015]
As described above, the upper end portion of the body 1 is in the form of a deep groove formed by arranging the band winding pieces 13 in parallel with the upright opening wall 7 via the ridges 9 and the wire connecting portions 11, and the lid 2 is formed. Is provided with a hanging peripheral wall 21 fitted into the deep groove and an inner peripheral ridge 23 joined to the inside of the upright opening wall 7, and a peripheral attachment groove is provided between the hanging peripheral wall 21 and the inner peripheral ridge 23. 24.

[0016]
Regarding the lock-like connection of the hanging peripheral wall 21, the hanging groove 25, 26 is provided in the upper and lower two steps on the band winding piece 13 (FIG. 3), and the hanging peripheral wall 21 is closely fitted to the hanging groove 25, 26. Engagement ridges 27 and 28 are formed. Then, if the band piece 13 is cut out by operating the knob 17 (see FIG. 6), the locking grooves 25 and 26 as mating members with which the engaging ridges 27 and 28 are engaged in the lid 2 disappear. As a result of losing the function of the lid preventing device R, the lid 2 can be freely opened and closed thereafter. At the corners of the container, the engaging ridges 27 and 28 are formed low.
[0017]
Further, the body 1 is formed low 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 position at both ends. I am going to receive it. In addition, a thread bottom 36 is formed at the lower end to be received in the recessed portion 33 of the lid 2.
[0018]
In addition, as for the concave shape of the lid 2, the inclined wall 31 is formed in an annular shape at a position close to the peripheral edge, so that the concave wall 33 has a wide concave portion 33 inside the inclined wall 31. Therefore, a partition attachment groove 37 is formed on the lower surface so as to closely fit the entire length of the partition wall 3 so as to match the recessed recess 33. Therefore, when closing the lid 2, first, the inclined portions 38, 38 of the partition attachment groove 37 are fitted into the paragraph inclinations 35, 35 of the partition wall 3 (see the two-dot chain line in FIG. 3). It becomes a leading guide that fits.
