TECHNICAL FIELD OF THE INVENTION
The present invention relates to a fitting container, and more particularly to a fitting container that can be resealed after the liquid portion of the contents is discharged.
[0002]
[Prior art]
For example, a Chinese cabbage pickled or kabu pickled pickled in an appropriate amount in a fitting container is commercially available. This container has a so-called both-fitting structure, and its upper surface is usually heat-sealed with an easy-peeling adhesive, and in use, the fitting is released while removing the lid, and the lid is removed. At this time, since the liquid component of the contents may scatter and stain the surroundings, be careful not to open the lid at the corner of the lid, which is usually provided with a tab, and then remove the lid after draining the liquid. The writing is displayed.
[0003]
[Problems of the Invention]
However, in order to discharge the liquid inside the container, it is necessary to fold the lid and partially open it to form a discharge passage. Once it is bent, it will be bent and will be resealed for storage etc. However, there is a problem that the bent portion is not securely fitted and the sealing performance is deteriorated, for example, the odor of pickles leaks to fill the refrigerator or the taste is lowered.
[0004]
Further, in this type of both fitting containers, the lid and the container main body are engaged with each other by fitting the channel-shaped concave stripes with the convex stripes, so that there is a problem that it is not easy to bend the lid.
[0005]
Therefore, an object of the present invention is to enable easy partial opening of the lid, smooth discharge of the liquid, and resealing with high sealing performance.
[0006]
[Means for solving problems]
In order to solve the above-described problems, the present invention provides a polygonal both-fitting container provided with a drainage groove extending from the inner edge to a middle portion of the upper surface of the convex portion of the corner portion of the container body , corresponding to the corner portion. A drainage groove that communicates with the drainage groove of the ridge and communicates with the inside of the container body is provided on the flange of the lid, and the depth of the drainage groove of the flange is set to a depth that leaves the inner wall of the recess at a predetermined height. A configuration is adopted in which a notch is provided in the outer skirt portion of the concave line substantially corresponding to both sides of the drainage groove of the lid . In addition, the ridges of the corners with the drainage grooves are widened, the corresponding concaves of the lid are widened, and the ridges and ridges of other corners without drainage grooves are the same width. It can be.

Embodiment
Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 3 show a container body. As illustrated, the container body 10 has a peripheral wall 12 that rises from the periphery of the bottom wall 11, and a flat flange 14 is provided on the outer periphery of the upper end opening 13 of the peripheral wall 12. On the upper surface of the flange 14, a ridge 15 is formed over the entire circumference. The ridges 15 are tapered so as to expand upward. Further, the ridges 15 are wide corner ridges 15a and 15b that are partitioned by a line substantially perpendicular to the center direction of the container body 10 at the corner, and one corner ridge 15a includes A drainage groove 16 extending from the middle part in the width direction to the inner edge is provided. Further, tabs 17a and 17b are provided on the flanges 14 corresponding to the corner ridges 15a and 15b, respectively.
[0008]
The lid 20 that covers the container body 10 is shown in FIGS. As shown in the drawing, a flat flange 24 corresponding to the flange 14 on the inner side of the ridge 15 of the container body 10 is provided on the outer periphery of the top wall 21, and the ridge of the container body 10 is provided on the flange 24. A recess 25 corresponding to 15 is formed over the entire circumference. The concave stripes 15 are wide corner concave stripes 25a and 25b corresponding to the wide convex stripes 15a and 15b of the container body 10 at the corner portion. These concave strips 25, 25a, 25b are preferably tapered so as to expand upward.
[0009]
A drainage groove 26 that is recessed upward is formed in a portion of the flange 24 corresponding to the one corner recess 25a, and substantially corresponds to both sides of the drainage groove 26 (may be inside or outside from both sides of the groove 26). ), Notches 28a and 28b are formed in the outer skirt portion 25c of the recess 25. As shown in FIG. 7, the notches 28 a and 28 b have upper ends that extend to the upper surface of the recess 25. The shape of the notches 28a and 28b may be an inverted V shape as shown in FIG. 7, an inverted U shape, or a simple straight cut. The lid 20 can be easily bent by the notches 28a and 28b. Further, tabs 27a and 27b are provided on the outer sides of the corner recesses 25a and 25b. The top wall 21 of the lid 20 may be of the same type as that of the flange 24 or a drop lid type, in addition to the raised lid type as shown in the figure. Further, as shown in FIG. 5, the depth of the drainage groove 26 must be formed to a depth that always leaves the inner wall 25d of the recess 25 by a predetermined height.
[0010]
A state in which the lid 20 is fitted to the container body 10 is shown in FIGS. As shown in FIG. 8, the portions of the normal ridges 15 and the ridges 25 are in close contact with each other because they are fitted together and the flanges 14 and 24 are also in close contact. In the portions of the corner ridges 15a and the ridges 25a to be shown, the drainage grooves 16 are provided in the ridges 15a, and the drainage grooves 26 are also provided in the flange 24 of the lid 20, so that the drainage grooves 16 and 26 communicate with each other. Although only the portion has no sealing property, the upper surface and the outer surface except the drainage groove 16 of the ridge 15a are in close contact with the inner surface of the recess 25a, so that the sealing property is sufficiently maintained. Further, the other corner ridges 15b and recesses 25b are in close contact with each other in the same manner as the projections 15 and 25 in FIG. 8, and the flanges 14 and 24 are also in close contact. If necessary, only the peripheral portion of the drainage groove 16 is heat-sealed on the upper surface of the ridges 15a and the inner surfaces of the ridges 25a, or the upper surface of the ridges 15 including the corner ridges 15a and 15b It can be heat sealed to the inner surface. Of course, in these cases, it is necessary to perform easy peel heat sealing.
[0011]
In order to drain the water while the contents are stored in the container, as shown in FIG. 10, the tab 27a of the corner portion where the drainage groove 16 is provided is lifted, and the projection 15a and the recess 25a are disengaged. At this time, as described with reference to FIGS. 7 and 4, since the skirt portion of the lid 20 is provided with the notches 28a and 28b, the corner portion of the lid 20 is bent along a line connecting the notches 28a and 28b. Partially opened. Therefore, when the container is tilted, the liquid in the contents is discharged from the drainage groove 26 through a passage formed by the drainage groove 16 communicating with the drainage groove 26. At this time, the drainage passage is partitioned by drainage grooves 26 and 16, and the lid 20 is opened only to the line connecting the notches 28a and 28b, that is, to both sides of the drainage groove 26 (see FIG. 4). The liquid to be sprayed will not be scattered.
[0012]
However, since the lid 20 is bent along the line connecting the notches 28a and 28b, the lid material (synthetic resin sheet) is deteriorated along the line, and a crease line is formed and it is easy to bend. Because of the communication, even if a part of the partially opened lid is fitted to the container body and resealed, a slight impact is applied to the container and the lid part easily rises when the internal pressure rises. The seal will be lost.
[0013]
Therefore, in order to retain the sealing property by resealing after discharging the liquid, as shown in FIGS. 11 and 12, the lid 20 is rotated by 180 ° so that the corner ridges 25 a are formed on the corner ridges of the container body 10. The lid 20 is fitted to the container body 10 so that the corner ridges 25b correspond to the corner ridges 15a. In this case, since the corner groove 25b does not have the drainage groove 26, the flange 24 and the flange 14 of the container body 10 are in close contact with each other, and the outer surface of the protrusion 15a other than the drainage groove 16 of the container body 10 is also formed. Since it is in close contact with the inner surface of the recess 25b, the sealing performance at the corner is maintained. On the other hand, there is a gap between the flange 14 and the drainage groove 26 in the corner recess 25a provided with the drainage groove 26, but there is no drainage groove 16 on the convex line 15b of the container body 10, The inner surface 25d inner surface of the recess 25a and the inner wall outer surface of the protrusion 15b are in close contact, and the inner surface (bottom surface) of the recess 25a and the inner surface of the skirt portion 25c are also in close contact with the upper surface of the protrusion 15b and the outer surface of the outer wall, Sealability is maintained. Therefore, the lid 20 can maintain the sealing performance over the entire circumference of the container body 10.
[0014]
The container is not limited to a quadrangle as shown in the figure, but may be a polygon such as a triangle or a pentagon. In the case of an odd-numbered square, the present invention cannot be applied unless it is a regular polygon. Moreover, in the case of a regular polygon, regardless of whether it is an even square or an odd square, a drainage structure and a structure for resealing it may be provided at any corner. For example, if drainage grooves 16 and 26 are provided in one corner portion, and corner protrusions 15b and recesses 25b for resealing are provided in all remaining corner portions, resealing is performed without rotating the lid 180 °. Is possible.
[0015]
【The invention's effect】
According to the present invention, as described above, the drainage passage is provided in one corner portion of the polygonal fitting container, and only the vicinity of the passage can be opened, so that the liquid component of the contents can be discharged. The liquid can be prevented from splashing around the container and its surroundings, and the corner with the drainage channel can be sealed with other corners, so just changing the lid angle and fitting Can be resealed.
