For this reason, the lid may not be appropriately deformed, and various inconveniences may be caused.

The present invention has been made by focusing on the problems existing in the prior art as described above. The first object is that when the jig presses the recess to deform the lid downward, even if the position of the packaging container is displaced, the inner surface of the recess and the jig are displaced. An object of the present invention is to provide a packaging container capable of slidingly contacting an outer surface of the packaging container and moving and correcting the packaging container to an appropriate position. A second object is to provide a packaging container capable of stacking and storing and transporting a plurality of packaging containers in a vertically stable state.

[0006]

In order to achieve the above-mentioned object, a packaging container according to the present invention has a tapered annular side wall whose side cross-sectional shape increases toward the upper side, and a lower end portion.

They can be stacked in a stable state.

On the other hand, when the viscous material 31 in the packaging container 11 is discharged, a discharge device 32 as schematically shown in FIG. 3 is used. In the discharge device 32, a receiving table 35, a mounting table 36, and a pressing table 37 are provided at predetermined intervals from one end of the supporting table 33 to the upper part of a supporting section 34 which is erected. In the discharge device 32, the receiving base 35 is configured to hold a receiving container 38 for receiving and storing the viscous material 31 such as a soft cream discharged from the extrusion hole 15 of the packaging container 11. ing.

The mounting table 36 is provided with a circular holding hole 39 for holding the packaging container 11 at the side wall 17 of the container body 12. This holding hole 39
As shown in FIG. 3, the inner surface is formed by an abutting surface 40 inclined so as to form a tapered shape that expands toward the upper portion, and can be fitted to the outer peripheral surface of the side wall 17 of the container body 12. ing.

On the other hand, on the pressing table 37, a support shaft 42 for supporting one end of the pressing lever 41 and a pair of spring members 43 for restricting the vertical movement of the pressing lever 41 are provided. A circular insertion hole 44 is provided between the spring members 43.
Are drilled. Further, the insertion hole 44 is located immediately above the holding hole 39 formed in the mounting table 36.
At the center of the pressing lever 41, an upper end of a pressing rod 45 is supported via a universal joint (not shown) and hangs down through an insertion hole 44 of the pressing table 37.

At the tip of the pressing rod 45, a pressing plate 46 formed of a metal or the like in a substantially disk shape is attached. The shape of the lower outer surface of the pressing plate 46 is
And a shape corresponding to the outer shape of the lower portion of the container body 12 and the inner shape of the recess 20 of the lid 13. Further, the pressing plate 46 is configured to be able to move up and down by operating the pressing lever 41.

When the viscous substance 31 in the packaging container 11 is discharged, first, the closing tape 16 is peeled off from the bottom surface of the packaging container 11 filled with the viscous substance 31.
As shown in FIG. 4A, the container body 1 of the packaging container 11
2 is inserted into the holding hole 39 of the mounting table 36. Next, FIG.
(B), as shown in FIG. 4 (c), FIG. 5 (a) and FIG. 5 (b), by lowering the pressing lever 41 and the pressing plate 46 at a predetermined speed, the inside of the packaging container 11 is reduced. The viscous material 31 can be discharged from the extrusion hole 15 and poured into the receiving container 38.

At this time, as shown in FIG.
When the packaging container 11 is inclined or deviated from a predetermined position and is engaged with the holding hole 39, as shown in FIG. 4B, the inner surface of the recess 20 in the lid 13 is pressed. As shown in FIG. 4 (c), the package container 11 moves while being in contact with the lower outer surface of the plate 46, and the packaging container 11 is placed at an appropriate position, that is, at a position where the extrusion hole 15 matches the center of the holding hole 39. Will be moved to be.

By further moving the pressing plate 46 downward, as shown in FIG. 5A, while the lower outer surface of the pressing plate 46 is in contact with the inner surface of the recess 20 of the lid 13, the lid 13 is lowered. Is pressed. At this time, the lid 13 is deformed, the polypropylene sheet constituting the protrusion 22 is stretched, and the viscous material 31 in the container body 12 is pushed out of the extrusion hole 15.
, And is discharged into the receiving container 38.

Further, as shown in FIG.
By moving the pressing plate 46 downward until the lower surface of the container 3 is in close contact with the inner surface of the container body 12, almost all the viscous material 31 in the container body 12 is discharged.

The effects exerted by the above embodiment will be described below. The packaging container 11 of the embodiment is provided at the center of the lid 13,
Since the recess 20 having the inner surface shape corresponding to the lower outer surface shape of the container body 12 is formed, the lower portion of the container body 12 is inserted into the recess 20 to stabilize the plurality of packaging containers 11 up and down. Can be stacked in a state. Therefore, when the packaging containers 11 are stored and transported, the stacked packaging containers 11 are unlikely to collapse, so that subsequent operations and the like can be easily performed without delay.

Further, the packaging container 1 is
1, the inner surface of the recess 20 is pressed even when the packaging container 11 is disposed at an angle or a position slightly deviated from a predetermined position. The guide function can be exhibited by contacting the lower outer surface of the plate 46. Therefore, it is possible to discharge the viscous material 31 from the inside of the packaging container 11 at the appropriate position where the movement has been corrected. Further, at this time, since it is not necessary to strictly position the packaging container 11 and dispose it on the mounting table 36, the work efficiency when the viscous material 31 is poured out from the packaging container 11 is further improved. It is possible.

Since the lid 13 is made of a deformable polypropylene sheet, the lid 13 is easily deformed by the pressing plate 46, and the viscous material 31 in the container body 12 can be easily discharged. . Furthermore, since the thickness of the polypropylene sheet is 0.3 mm, it is possible to deform the lid 13 very smoothly. Further, at this time, the viscous material 31 in the container body 12 can be discharged at a constant discharge amount, and the remaining amount of the viscous material 31 in the container body 12 after the discharge can be reduced. Further, the thickness of this polypropylene sheet is very thin, and it is economical because the amount of polypropylene required for production can be reduced.

Since the lower surface of the lid 13 is configured to be in close contact with the inner surface of the container main body 12 by pressing the recess 20 of the lid 13, the viscous substance 31 in the container main body 12 is discharged. It is economical because the remaining amount of the viscous material 31 in the container body 12 after being made can be almost eliminated.

Since the center of the recess 20 of the cover 13 is formed by the flat surface 21 and the lower outer surface of the container body 12 is formed to correspond to the inner shape of the recess 20 of the cover 13, When the containers 11 are stacked up and down,
The upper and lower packaging containers 11 are stacked with their flat surfaces in contact with each other. For this reason, the packaging container 11
Can be stacked up and down in a very stable state. Further, at this time, the peripheral portion of the recess 20 located below, that is, the protrusion 22 is
, It is possible to further improve the stability when the packaging containers 11 are vertically stacked. Further, the flat surface constituting the bottom surface of the container body 12 can enhance the stability of the container body 12 when the packaging container 11 is placed on a desk or the like.

In the packaging container 11, the height of the flat surface 21 which is the lower end of the recess 20 of the lid 13 is formed to be substantially the same as the height of the upper opening of the container body 12. I have. For this reason, the viscous material 31 can be filled up to the height of the upper opening of the container body 12, and the packaging space in the container body 12 is large and effectively used while the packaging container 11 is formed compact. It is possible to

Since the projection 22 of the lid 13 is formed to be narrow, the space occupied by the recess 20 in the lid 13 can be made large. For this reason, since the flat surface of the bottom of the container main body 12 can be formed widely, when the container main body 12 is placed on a desk or the like and when the packaging containers 11 are stacked vertically, 1
2 can be in a stable state.

Since the projecting portion 22 of the lid 13 is configured so as not to be filled with the viscous material 31, the viscous material 31 is changed by a change in the temperature, the atmospheric pressure or the like during the storage or transportation of the packaging container 11. Even when the volume expands, the air in the protrusion 22 is expelled, so that the closed state of the packaging container 11 can be maintained. Conversely, the viscous material 31
When the volume of the container shrinks, the packaging container 11
It is possible to prevent a collapse with the contraction of the first.
