Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a food storage container, and more particularly to a storage container for pudding, jelly, chicken pox and other viscous foods.
[0002]
[Prior art]
In storage containers such as pudding, a small rod is erected on the top plate (the container bottom plate which is inverted when the contents are taken out), and the small rod is pushed down to form an air hole so that air is introduced into the container. A storage container that is formed so as to be separated from the peripheral wall portion by pressing downwardly and is configured to separate viscous pudding, jelly, and the like from the peripheral wall by pushing down the top plate is conventional as seen in, for example, Japanese Utility Model Publication No. Hei 6-61788. More known.
[0003]
[Problems to be solved by the invention]
However, in the above-described conventional container, the peripheral wall and the top plate are integrally formed so that the top plate is joined to an inward flange provided on the peripheral wall by insert formation.
Therefore, in forming the storage container, there has been a problem in that the top plate forming, the container forming, and the two forming steps are required.
[0004]
In order to make the top plate easily separated from the inward flange provided on the inner periphery of the peripheral wall, different types of synthetic resin are used. If the top plate is not separated during disposal, different materials will be mixed during the waste recycling process. There was a problem to do.
[0005]
The present invention has a technical problem to solve the above-mentioned problems, and when taking out the contents, the container is inverted and the concave wall surface formed on the bottom wall is inverted inward, so that pudding, jelly, etc. having viscosity can be obtained. An object of the present invention is to provide a food storage container that is pressed and separated from a peripheral wall to fall.
[0006]
[Means for Solving the Problems]
In order to achieve the above technical problem, the present invention provides a food storage container including a conical peripheral wall, a bottom wall, and a bottom end cylindrical wall extending downward from the bottom wall as a storage container for food such as pudding. An air hole forming pin is suspended from the bottom wall lower surface, and a concave wall surface that can be reversed with respect to the bottom wall surface is formed at a predetermined position of the bottom wall.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the storage container is formed of synthetic resin and includes a conical peripheral wall 1 and a bottom wall 2.
A flange 3 is continuously provided at the upper end of the peripheral wall 1, and a bottom end peripheral wall 4 extending downward from the bottom wall 2 is continuously provided below.
[0008]
An air hole forming pin 5 is provided on the lower surface of the bottom wall 2, and an annular notch groove 6 is engraved on the upper surface of the bottom wall 2 along the periphery of the root of the pin 5.
When the container is inverted and the pin 5 is folded down, the notch groove 6 is opened and the pin 5 is cut off from the bottom wall, and the air hole 7 can be opened as shown in FIG.
[0009]
A spherical concave wall surface 8 is formed on the opposite side of the pin 5 across the center of the bottom wall 2, and a thin portion 9 is formed on the periphery of the concave wall surface 8 of the bottom wall 2. By pressing from the outside, the concave wall surface 8 can be inverted so that the spherical surface faces inward.
[0010]
In the container, foods having viscosity such as pudding, jelly, and water sheep are stored as contents, and the upper surface of the flange 3 is sealed with a film, a sheet or the like.
As shown in FIG. 3, when eating and drinking, the seal is peeled off, the container is turned upside down and placed on a plate, and the pin 5 is folded down to form an air hole 7. The contents P fall by their own weight.
In the case where the adhesiveness is high and does not fall, when the concave wall surface 8 protruding upward is pressed, the concave wall surface 8 is inverted so that the spherical surface faces downward, and the contents P such as pudding are pushed down by the inverted spherical surface, Can be dropped away.
[0011]
In the above embodiment, the concave wall surface 8 is provided on the opposite side of the pin 5 across the center of the bottom wall 2, but the spherical concave wall surface 8 may be provided so that its center is located at the center of the bottom wall 2 ( The position of the concave wall surface 8 is not limited.
Also, the shape of the concave wall surface may be a trapezoidal concave wall surface having a square periphery with arcs at the corners, and the shape of the concave wall surface is not limited to a spherical surface.
[0012]
In the above-described embodiment, the peripheral wall 1 has a conical shape. However, if the contents have a predetermined taper surface and the contents are separated from the container peripheral wall and fall when inverted, the shape of the cross section of the peripheral wall is a corner portion. The shape may be a square, ellipse, star, or a flower shape with circular arcs arranged on the circumference (not shown).
In particular, in the case of a star shape or a flower shape, there is a problem that the contents are not easily separated from the peripheral wall, but the shape can be easily separated by the reversal action of the concave wall surface 8 together with the pin 5.
Therefore, the shape of the food container can be diversified, and the consumer's preference can be met.
[0013]
【The invention's effect】
Since this invention is comprised as mentioned above, there exists the following effect.
The bottom wall is provided with a concave wall surface with an air hole forming pin, the container is inverted when the contents are taken out, and the wall surface of the concave wall surface is inverted downward, so that even highly sticky contents can be easily separated from the peripheral wall and dropped. Can be made.

FIG. 1 is a longitudinal sectional view of a container.
FIG. 2 is a bottom view of the container.
FIGS. 3A and 3B are explanatory diagrams when the contents are taken out, in which FIG. 3A is when the container is turned upside down, and FIG.
