Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealed container for storing and storing pickles and the like, and relates to a technique for easily opening and closing a lid.

[0002]

2. Description of the Related Art In a convenience store or the like, irregular-shaped foods such as pickles and boiled beans are often sold in a closed container made of a transparent synthetic resin and then displayed in a refrigerator case. Generally, as this kind of closed container,
A so-called round shape with a cylindrical shape or a truncated cone shape, and a square shape or a rectangular shape are used. The container body and the lid are heated by an electric heater (heat sealer) to prevent liquid leakage and intrusion of outside air. Has been fused.

[0003] When taking out food from a closed container, a purchaser pulls open the lid from the container body in the form of peeling off the heat-sealed portion. Therefore, the lip portion is provided on the container main body and the lid in the rectangular closed container, and the purchaser grasps each lip portion with both fingers and pulls the lid upward. At this time, the purchaser can easily and stably open and close the lid by holding the container body and holding the container body while holding the container body on a table or a sink. I can do it.

[0004]

By the way, in the round-shaped closed container, the lip portion is provided only on the lid side for the following reason. That is, when heat-welding the round container body and the lid, first, the container body is dropped into the hollow portion of the cylindrical die (bucket), and the container body is fixed to the container body having the flange fixed to the upper end of the bucket. Put the lid on. Thereafter, the annular heat sealer is lowered from the upper part of the bucket, and the high-temperature heat sealer heats and fuses the two together while pressing and closely contacting the flange of the container body and the outer peripheral edge of the lid. However, when the lip portion is formed on the container body, the container body or the lid already filled with food is rotated in the rotation direction in order to keep the lip portion on the lid side and the lip portion on the container body side in a predetermined positional relationship. A need arises for alignment. Since this operation becomes complicated, the lip portion on the container body side is omitted in the production line on the premise of mass production.

[0005] Therefore, when taking out food or the like from the container body, the outer peripheral portion and the like of the container body are held with one hand,
In order to peel off the heat fusion between the container body and the lid, it is necessary to grasp the lip of the lid with the finger of the other hand and pull it up strongly,
Pulling workability was extremely poor. In addition, when food such as pickles containing a large amount of liquid is filled in the closed container, the container body is inevitable to dance at the moment when the lid is pulled out from the closed container, and the liquid (drip) scatters from the container body. There is a possibility that the table, clothes, etc. may be stained. In addition, since the lip portion provided only on the lid is strongly pulled up, an excessive force acts on the lid, and the outer edge portion is deformed. There was a problem that worsened. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a closed container having a round container main body, in which a lid can be easily opened and the like.

[0006]

In order to solve the above-mentioned problems, according to the first aspect of the present invention, a substantially cylindrical shape or a substantially truncated cone shape having an open upper portion is formed, and a flange is formed on an outer peripheral portion of an upper end. A container body, an outer peripheral edge is detachably fixed to the flange of the container body, a closed container consisting of a lid that seals the container body, the flange of the container body and the outer peripheral edge of the lid, It is proposed that a lip portion provided for opening and closing the lid is formed, and a positioning means provided for positioning in the rotation direction is formed on the container body.

According to a second aspect of the present invention, there is provided the closed container of the first aspect, wherein the positioning means is a concave portion or a convex portion provided on a side surface of the container body.

According to a third aspect of the present invention, there is provided the closed container according to the first aspect, wherein the positioning means is a polygon formed on a side surface of the container body.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing a sealed container made of a transparent synthetic resin according to the first embodiment, and FIG.
It is AA sectional drawing in a middle. As shown in these drawings, the hermetically sealed container 1 has a truncated cone-shaped container body 5 having a flange portion 3 at the upper end, and an annular convex portion 7 fitted on the flange portion 3 of the container body 5 on the outer periphery. And a lid 9. The container main body 5 and the lid 9 are integrated by filling the container main body 5 with food or the like, and then heating and fusing the flange portion 3 and the lid 9 together. In FIG. 2, reference numeral 11 denotes a heat-sealing portion.

The container body 5 has a main body side lip 13 extending from the flange 3, and the lid 9 also has a lid side lip 15 extending from the annular projection 7. Both lip parts 13,
15 are located at substantially the same position, but have slightly different angular phases on the distal end side so that they can be easily gripped with the fingers of both hands. The container body 5 has a body-side lip portion 13.
A concave portion 17 is formed immediately below.

The operation of the first embodiment will be described below with reference to FIGS. In the case of the first embodiment, as shown in FIG.
A positioning protrusion 23 is formed at a position corresponding to the concave portion 17 of FIG. Therefore, when the manufacturing operator puts the container body 5 filled with the food 25 such as pickles into the bucket 21 at a predetermined angle phase, as shown in FIG.
Recess 17 is engaged with and positioned by the positioning projection 23. However, if the angular phase of the container body 5 at the time of insertion is out of alignment, as shown by the two-dot line in FIG. The angle phase of the container body 5 can be easily corrected.

When the container body 5 is held by the bucket 21, the lid 9 is put on the container body 5 by a hopper or the like as shown in FIG. At this time, since the lid 9 is always covered with the same angle with respect to the container main body 5, the positional relationship between the container-side lip portion 13 and the lid-side lip portion 15 is appropriately maintained. Next, as shown in FIG. 6, the annular heat sealer 27 descends toward the bucket 21, and heat-fuses while pressing the flange portion 3 of the container body 5 and the annular convex portion 7 of the lid 9.
Thereby, as shown in FIG.
The sealed container 1 is completed in a state in which 5 is at the substantially same position.

FIG. 7 is a perspective view showing a closed container according to the second embodiment. The overall configuration of the second embodiment is substantially the same as that of the first embodiment described above, but differs in the method of positioning the container body. That is, in the present embodiment, the container body 5
The lower side is formed in a hexagonal portion 31, while a hexagonal locking portion corresponding to the hexagonal portion 31 of the container body 5 is formed on a bucket side (not shown). In the present embodiment, such a configuration is adopted. Therefore, when the manufacturing worker does not throw the container body 5 into the bucket at a regular angle, the deviation angle is 6 degrees.
0 ° or more. Therefore, the manufacturing operator can immediately recognize an error in the input angle of the container main body 5, and can easily correct the angular phase of the container main body 5.

The description of the specific embodiment has been completed.
The aspects of the present invention are not limited to these embodiments. For example, in the first embodiment, one concave portion is formed on the lower side surface of the container body, but a convex portion may be formed, or a plurality of concave portions and convex portions may be formed. Good. In the second embodiment, the lower part of the side surface of the container body is hexagonal, but may be the upper side surface, may be pentagonal or less, or may be heptagonal or more. In addition, the shape of each part in the container main body and the lid, the method of fixing the two, and the like can be appropriately changed without departing from the gist of the present invention.

[0015]

According to the closed container of the present invention, it is possible to provide the lip portion on both the container body and the lid while having the round container body, so that the pulling-out workability is greatly improved. In addition to this, scattering of the drip and deformation of the lid at the time of the pulling-out operation do not occur, thereby preventing the table and the clothes from being soiled and the resealing property from being deteriorated.
